The objective of this investigation was to compare the clinical performance of a nano-hybrid resin composite and a low-shrinkage Giomer resin composite. Material and methods: In total, 35 pairs of restorations were performed using either low-shrinkage Giomer (Beautifil II LS, Shofu Inc.) or nano-hybrid (Clearfil Majesty Posterior) resin composite in 35 patients by two operators using the relevant adhesives, i.e., FL-Bond II (Shofu Inc.) and Clearfil SE Bond (Kuraray), with the self-etching technique according to each manufacturer's instructions. Two clinicians assessed the restorations 2 weeks (baseline); 6 months; and 1, 2, and 3 years after the restorative procedures using FDI (World Dental Federation) criteria (Scores 1-5). Data were analyzed using the marginal homogeneity and McNemar tests. The survival rate was calculated using Kaplan-Meier survival analysis and the survival of the two groups was compared with the log-rank test ( p = 0.05). Results: The mean observation period was 37.7 ± 6.8 months. All restorations completed their 3-year follow-up. The criteria were mainly rated with high (1 or 2) scores for quality in both groups. Only one restoration in the low-shrinkage Giomer resin composite group was accepted as a failure at the 2-year recall due to retention loss. Conclusion: At the 3-year follow-up, the performance of the restorations using the Giomer and the nano-hybrid resin composite were similar and clinically acceptable. Clinical relevance: The low-shrinkage Giomer resin composite exhibited a similar clinical performance to the nano-hybrid resin composite after 3 years in service with both materials displaying minor surface deteriorations at the 3-year recall.

Images In this work we present an automatic algorithm for detection of mycobacterium tuberculosis from stained sputum smear images applying a novel method of tubeness filtering in conjunction with Otsu thresholding and connected component analysis. This eliminates human effort and measurement error from the detection of the bacteria, which normally requires a lab technician or pathologist to load a glass slide with a patient’s stained sputum smear into a digital fluorescent microscope and visually search for mycobacterium tuberculosis in several different fields of view. On the other hand, the proposed automated detection of mycobacterium tuberculosis from stained sputum smear digital images renders fast analysis of patient’s sputum for quick and efficient diagnosis of tuberculosis.

Most studies on product package design elements have conceptualised the role of visual package elements such as colour, shape, size and picture in influencing consumer buying behaviour of fast moving consumer goods. Limited researches have focused on the impact of informational package elements on the purchase decisions of university students, therefore, this paper sought to examine the impact of informational package elements (brand elements, nutritional information, and food label information) on university students' purchase decisions of breakfast cereals. A descriptive research design was employed and the random sampling strategy was used to identify and select study participants constituting 100 respondents. The research findings revealed that the brand name, nutritional information on energy and sugar, and use instructions are critical determinants of university students' purchase decisions. Therefore, the implication for managers is that, the noted variables should be strategically managed as they are vital extrinsic cues that directly trigger consumer interest and shape their purchase decisions.

M ismatch of lesion visibility between diffusion-weighted image and fluid-attenuated inversion recovery image (DWI-FLAIR mismatch) is a useful surrogate marker for estimating the lesion age in ischemic stroke. Reperfusion therapy based on multimodal imaging, including the information on DWI-FLAIR mismatch, is considered feasible and safe in patients with unclear-onset stroke. However, FLAIR signal intensity within an acute DWI lesion is heterogeneous, and subtle changes limited to the partial region were often regarded as negative for FLAIR signal change. Because the lesion conspicuity is subjective, inter-rater agreement of FLAIR signal change was low, especially in subtle changes. Quantitative analysis of FLAIR signal intensity ratio failed to increase the specificity for predicting ischemic lesions within the therapeutic window 7 or the inter-rater agreement on FLAIR signal change. Color coding may increase the visual distinguishability, thus enabling clinicians to identify small changes in signal intensity. We hypothesized that color-coded FLAIR images would enhance the inter-rater agreement of DWI-FLAIR mismatch. The records of patients with ischemic stroke admitted to Asan Medical Center <24 hours of clear onset between January and July 2013 were reviewed. Patients were excluded if (1) DWI lesion was absent, (2) images were obtained from other centers, or (3) imaging data quality was insufficient. Clinical data were obtained from a prospectively collected registry. The Institutional Review Board of the Asan Medical Center approved this study. Informed consent was not obtained because of the retrospective design. Patients received a 1.5-T MRI scan (Magnetom Avanto; Siemens). The DWI slice with the largest lesion and the slice of corresponding FLAIR image were prepared. The FLAIR image slice was extracted Background and Purpose-Diffusion-weighted image fluid-attenuated inversion recovery (FLAIR) mismatch has been considered to represent ischemic lesion age. However, the inter-rater agreement of diffusion-weighted image FLAIR mismatch is low. We hypothesized that color-coded images would increase its inter-rater agreement. Methods-Patients with ischemic stroke <24 hours of a clear onset were retrospectively studied. FLAIR signal change was rated as negative, subtle, or obvious on conventional and color-coded FLAIR images based on visual inspection. Interrater agreement was evaluated using κ and percent agreement. The predictive value of diffusion-weighted image FLAIR mismatch for identification of patients <4.5 hours of symptom onset was evaluated. Results-One hundred and thirteen patients were enrolled. The inter-rater agreement of FLAIR signal change improved from 69.9% (k=0.538) with conventional images to 85.8% (k=0.754) with color-coded images (P=0.004). Discrepantly rated patients on conventional, but not on color-coded images, had a higher prevalence of cardioembolic stroke (P=0.02) and cortical infarction (P=0.04). The positive predictive value for patients <4.5 hours of onset was 85.3% and 71.9% with conventional and 95.7% and 82.1% with color-coded images, by each rater. Conclusions-Color-coded FLAIR images increased the inter-rater agreement of diffusion-weighted image FLAIR recovery mismatch and may ultimately help identify unknown-onset stroke patients appropriate for thrombolysis.

The monochrome ink medium, long celebrated for its visual economy, emerges in the Yuan period as an unexpected conduit of sound. The cicada, an insect of little pictorial appeal yet endowed with a piercing cry, became a recurring motif in Yuan painting, inviting a synesthetic engagement—one that commands the viewer to "listen through the eye." This paper explores how Yuan artists, particularly those working within the plant-and-insect genre, deployed the cicada as a vehicle of lament, its shrill wail resonating with the era’s political disquiet. By tracing the transformation of cicada imagery from polychrome renderings to stark monochrome forms, the study reveals a shift in pictorial sensibility: from naturalistic observation to an ink-driven aesthetic of expressive minimalism. Against the backdrop of dynastic upheaval and Song loyalist mourning, the cicada’s cry becomes an elegy, its form a visual echo of poetic lament. Through close readings of key scrolls—including A World of Vitality (1321) and Eight Objects: Plants and Insects (1330)—the paper argues that Yuan artists achieved a new mode of pictorial articulation, one where ink itself acquired a voice, not merely recording but enacting historical pathos.

We conducted a consumer acceptability analysis of dry-cured ham based on sensory evaluation. Consumer acceptability data are rendered heterogeneous by the diverse backgrounds and assessment abilities of the participants, requiring versatile analytical methods for their interpretation. Totally, 9 sensory attributes of 12 kinds of dry-cured ham samples collected from Japan (n=9), Italy (n=1), Spain (n=1), and Germany (n=1) were tasted by 117 Japanese consumers who showed acceptable evaluation abilities during blind sampling. Common techniques, such as hierarchical clustering, principal component analysis, and external preference mapping, were simultaneously utilized to analyze each characteristics scored in modified hedonic scale. These analyses revealed the relationships between the features and preferences of the assessors. For example, consumers aged 20-30 with smoking and drinking habits preferred sweetness and saltiness, and gave high ratings to Spanish Jómon serrano and Italian ...

نظرية ألبرت مونسيل (Albert Munsell):

    قام بتطوير نظام Munsell Color System في أوائل القرن العشرين، والذي يصنف الألوان بناءً على ثلاثة أبعاد رئيسية:
        Hue (الصبغة أو اللون الأساسي)
        Value (القيمة أو درجة السطوع)
        Chroma (التشبع أو الشدة اللونية)
    يُستخدم هذا النظام في الطباعة والتصميم الفني والعلوم.

نظرية فيلهلم أوستفالد (Wilhelm Ostwald):

    قدم نظامًا للألوان يعتمد على الانسجام اللوني وطور نموذجًا يعتمد على خلط الألوان بنسب محسوبة.
    ركز على العلاقة بين الألوان المكملة وكيفية تحقيق التوازن البصري في التصميمات.

نظرية شفرويل (Michel-Eugène Chevreul):

    وضع قانون التباين المتزامن للألوان (Simultaneous Contrast)، الذي يوضح كيف أن الألوان المجاورة تؤثر على إدراكنا لبعضها البعض.

Recent advances in pedestrian detection, a fundamental problem in computer vision, have been attained by transferring the learned features of convolutional neural networks (CNN) to pedestrians. However, existing methods often show a significant drop in performance when heavy occlusion and deformation happen because most methods rely on holistic modeling. Unlike most previous deep models that directly learn a holistic detector, we introduce the semantic part information for learning the pedestrian detector. Rather than defining semantic parts manually, we detect key points of each pedestrian proposal and then extract six semantic parts according to the predicted key points, e.g., head, upper-body, left/right arms and legs. Then, we crop and resize the semantic parts and pad them with the original proposal images. The padded images containing semantic part information are passed through CNN for further classification. Extensive experiments demonstrate the effectiveness of adding seman...

The influence of post fermentative addition of American barrel-shoot wastes on phenolic composition and chromatic quality of Syrah red wines has been evaluated as an environmentally sustainable alternative to the conventional winemaking for avoiding the common color loss of red wines elaborated in warm climates. American oak wood byproducts added were previously classified by hyperspectral image analysis according to the amount of phenolic compounds transferred to the extraction media. After that, wines were elaborated under different maceration conditions by applying only one proportion of wood (12 g L−1) and two different maceration procedures (simple and double addition) and were compared with a traditionally macerated Syrah red wine (CW, no wood addition). Results proved the effectiveness of the moderate postfermentative addition of oak wood byproducts to stabilize the color of wines and to provoke lower color modification along the time, producing color wines chromatically more...

Three independent methodologies were investigated to achieve the differentiation of red grapes from different grape varieties (Garnacha, Graciano, Mazuelo and Tempranillo) collected from five vineyards located in the D.O.Ca. Rioja. Anthocyanin chromatographic analysis, color image analysis and near infrared hyperspectral imaging were carried out for the grapes. Then, a Stepwise Linear Discriminant Analysis (SLDA) was developed for each data set in order to discriminate grapes according to their grape variety. As a result, using anthocyanin profile, color image analysis and near infrared hyperspectral imaging respectively, 88%, 54% and 100% of the samples were correctly classified in the internal validation process and 86%, 52% and 86% were correctly classified in the leave-one-out cross-validation process.

The attempt was made to find a correlation between the density of thermally modified pinewood treated at various temperatures and times and its compressive strength and modulus. The highest correlation coefficients were obtained for the temperature of 160°C and short modification times. Under these conditions, an increase of strength properties occurred. The highest size changes of the analysed samples were observed at higher temperatures, accompanied by a marked weight loss and decrease in both compressive strength and modulus of elasticity. The data obtained allow predicting modified wood strength on the base of its density. Changes in the density and strength of modified wood are caused by a fundamental change in the structural composition of the wood.

Six samples of virgin olive oil obtained from several varieties of olive fruits (Picual, Manzanilla, Lechín, and Arbequina) were submitted to an accelerated oxidation process during a 63‐h period under the conditions of the oil stability index (OSI), as measured by a Rancimat (100°C) apparatus. Spectra were measured every 3 h, and chlorophyll and carotenoid indexes and CIFLAB color ordinates were calculated. As oxidation time increased, remarkable changes in the spectral characteristics and color ordinates were observed. Oxidation provoked less vivid colors (lower values for chroma, C*ab) in all the samples; however, only some varieties became darker (lower values for lightness, L*). The pigment loss calculated for oxidized oils was 67% for the carotenoid index and 58% for the chlorophyll index. Mathematical models are offered to predict color changes with time of storage at 20°C.

The differences in color coordinates obtained from the use of different spectral features in the calculation are studied. Seven groups of food (olive oil, vanilla milkshake, brandy, honey, grape juice, vinegar, and orange juice) and an anthocyanin petunidin solution (natural pigment present in several vegetables) with different pH values were selected. Tristimulus values were calculated by considering the different sources of errors (truncation, abridgement, or different bandwidths). Results obtained were corrected by using the methods recommended (see References). These methods of abridgment work well in general, although in some circumstances (20 nm bandwidth or larger), specific spectral weighting functions have to be used to obtain a negligible error. Therefore, it is interesting to know how much difference can be expected from those factors in order to avoid confusion between color differences attributable to instruments and those attributable to actual color changes.

Non-centrifugal cane sugar (NCS), also called ''panela", is a high carbohydrate-content food obtained by boil evaporation of the sugar cane juice. This study was undertaken to assess physicochemical properties and sensory characteristics of panela beverage at two different concentrations. Evaluation of pH, °Brix, and colour (tristimulus colorimetry) was carried out in all panela drink samples. In order to characterise the odour-active volatiles of the beverage, a simultaneous steam distillation-solvent extraction method was applied using a mixture of diethyl ether-pentane (1:1, w/w) as solvent. The Aroma Extract Dilution Analysis revealed the presence of six odour-active compounds, being 2-methyl pyrazine the key aroma compound of this beverage. PCA (Principal Component Analysis) showed that there were no differences in the aroma and physicochemical properties (pH and °Brix) with respect to the geographical origin of analysed samples; however colour depends on heating during processing of NCS.

Three different varieties of Opuntia ficus-indica (R, red; Y, yellow; RY, red-yellow) have been considered in this study. Attention was focused on differential tristimulus colorimetry and on the analysis of individual betalains (HPLC-DAD-ESI-ToF-MS) and phenolic content, scarcely previously reported in these kinds of samples. The importance of this research stems from the elucidation of the parts and varieties of cactus pear more optimal for use as natural colorants and sources of phenolics and betalains. Thus, the RY pulp was appropriate to obtain colorants with high color intensity (C* ab = 66.5), whereas the whole Y fruit and R pulp reached powerful and stable yellow and red colors, respectively (C* ab /h ab , 57.1/84.7 and 61.1°/81.8°). This choice was also based on the visually appreciable differences (ΔE* ab > 5) among samples, mainly quantitative (%Δ 2 L, %Δ 2 C). In addition, seeds of all Opuntia varieties showed significantly (p < 0.05) similar phenolic content (around 23.3 mg/g) and color characteristics.

ZnO-based light emitting diodes (LEDs) have been considered as a potential candidate for the next generation of blue/ near-UV light sources, due to a direct wide bandgap energy of 3.37 eV, a large exciton binding energy of 60 meV at room temperature, and several other manufacturing advantages of ZnO. While the pursuit of stable and reproducible p-ZnO is still undergoing, heterojunctions of n-ZnO and p-GaN are employed as an alternative approach in this regard by considering the similar crystallographic and electronic properties of ZnO and GaN. Compared with the thin fi lm/thin fi lm LEDs, [ 5,6 , 8 ] which may suffer from the total internal refl ection, n-ZnO nanowire/p-GaN thin fi lm heterostructures are utilized in order to increase the extraction effi ciency of the LEDs by virtue of the waveguiding properties of the nanowires. But in all of these cases, the n-ZnO nanowires are randomly distributed on the substrate, which largely limits their applications in high performance optoelectronic devices. Here in this work, we demonstrate the capability of controlling the spatial distribution of the blue/near-UV LEDs composed of position controlled arrays of n-ZnO nanowires on a p-GaN thin fi lm substrate. The device was fabricated by a conjunction of low temperature wet chemical methods and electron beam lithography (EBL). The EBL could be replaced by other more convenient patterning techniques, such as photolithography and nanosphere lithography, rendering our technique low cost and capable of scaling up easily. Under forward bias, each single nanowire is a light emitter. By Gaussian deconvolution of the emission spectrum, the origins of the blue/near-UV emission are assigned particularly to three distinct electronhole recombination processes. By virtue of the nanowire/thin fi lm heterostructures, these LEDs give an external quantum effi ciency of 2.5%. This approach has great potential applications in high resolution electronic display, optical interconnect, and high density data storage. The design of the LED is shown in Figure . Ordered ZnO nanowire arrays were grown on p-GaN (Figure ),

The present study examined the effects on dentin ablation efficiency arising from various pulse durations of Er: YAG laser at a fixed energy fluence. Ten flat human dentin disks were prepared and exposed to an Er: YAG laser at 1 pps for three seconds at pulse durations of 100 -500 μsec with 150 mJ/pulse (40.0 J/cm 2 •pulse). The depth and diameter of the ablated dentin were measured and the ablation volume was estimated. Irradiated surfaces and cross-sections were observed using a SEM. Depth of the removed dentin increased and the diameter of the spot decreased without a change in the estimated volume at increased pulse durations. SEM observation of the irradiated surfaces revealed that there were no morphological differences when the pulse duration was changed. When the specimens were cross-sectioned, the ablated dentin had a dome shape and there was a dark layer under the irradiated surface.

La preferencia del consumidor por alimentos de alta calidad ha promovido la creación de nuevos sistemas de conservación, siendo esto especialmente inducido por factores como la demanda de alimentos mínimamente procesados y la aparición de nuevos patógenos. La tecnología de ozonización proporciona importantes beneficios sobre la calidad de los alimentos, destacando por el principal atributo del ozono como agente antimicrobiano, con un amplio espectro de acción, además de ser una tecnología novedosa en la descontaminación química, reciclamiento de aguas residuales y mejora de propiedades en los alimentos. Hoy en día, esta tecnología presenta una amplia adopción comercial a nivel mundial, contando con importantes aprobaciones de organismos reguladores por ser una alternativa no-térmica, verde y bioamigable; incluso, su certificación como aditivo alimentario se debe a su naturaleza ecológica de fácil degradación, en comparación con otros métodos. Existen relevantes investigaciones enfocadas a la aplicación del ozono que muestran sus beneficios en variados sectores de esta industria. En el presente artículo se analiza sistemáticamente el papel del ozono en eficientar tanto la inocuidad como la calidad de los alimentos, destacando las propiedades de este compuesto, sus mecanismos de acción y algunas aplicaciones con alto potencial de uso en esta industria.

This paper discusses convolution algorithms to reconstruct off-axis digital holograms. The problem of convolution is addressed by considering the spatial spectral properties of digital holograms, especially the unusual localization property of the Fourier spectrum of the hologram, in regard to the physical object space. After deriving the sampling requirements for the transfer functions, three approaches are considered with the concept of spatial bandwidth extension: zero padding, spectrum scanning, and adjustable magnification. The theoretical discussion is completed by experimental illustrations that enable the algorithms to be objectively compared.

Sherry-type pale white wines were subjected under different stirring times to color correction treatments based on the use of variable concentrations of free yeast and a single concentration of yeast immobilized on carrageenan gel. At all concentrations tested, the free yeasts decreased the A420 of the initial wine. The immobilized yeast showed slightly lower effectiveness to retain browning compounds of the wine and exhibited no significant differences among the treatment times assayed. Choosing the most unfavorable conditions (24 h), significant decreases in the concentrations of low-molecular-weight phenolic compounds were observed. The sensory properties of the wines treated with the immobilized yeast were shown to be similar to those of wines treated with activated charcoal for flavor, better for color, and slightly worse for aroma. Keywords: browning, immobilized yeast, white wines, fining agents Unclarified white wines, obtained by biological aging in the

ABSTRACTThe trichromatic theory was applied to wines at the end of the 1930s. Trichromatic co‐ordinates, dominant wavelength, purity and luminance were determined. The Munsell system and the Lovibond method, which had industrial applicability, were compared with the simplified methods proposed by the L&#39;office Internationale de la Vigne et du Vin (OIV). These methods are official in Spanish food regulations on wine analysis. The CIE recommendations, through the weighted ordinate method, set up the colorimetric parameters for wines, such as hue, lightness, purity or saturation, differences of color, perceptibility. Lately, attempts have been made to correlate the chromatic properties of wines with composition, origin, aging and sensory evaluation. Some authors have studied the reliability of the OIV methods versus the more rigid recent CIE methods. Improved formulae for the computation of dominant wavelength and outstanding correlations among sensorial scores, chromatic parameters...

Dominant wavelength is a representative variable of the hue useful for the characterization of the eolour of red wines. It is usually obtained through a conventional graphical method on the CIE 1931 (x,y) diagram. In this work, three alternative formulae for calculating dominant wavelength are checked on two sample groups of red and ros6 wines which consist of 109 Spanish wine samples and 66 samples taken from authors in the reference list respectively. A novel polynomie quotient expression obtained by applying the 'derivative-free nonlinear regression method' is proposed for an accurate calculation of dominant wavelength.

A prototype X-ray colour imaging system has been assembled using the principle of tomographic energydispersive diffraction imaging (TEDDI ). The new system has been tested using samples of nylon-6, aluminium powder and deer antler bone. Non-destructive three-dimensional images of the test objects have been reconstructed on a 300 mm scale with an associated diffraction pattern at each voxel. In addition, the lattice parameters of the polycrystalline material present in the sampled voxels have been determined using full pattern refinement methods. The use of multiple diffracted parallel colour X-ray beams has allowed simultaneous spatially resolved data collection across a plane of the sample. This has simplified the sample scan motion and has improved data collection times by a factor scaling with the number of detector pixels. The TEDDI method is currently limited to thin samples (approx. 1-2 mm) with light atoms owing to the very low detection efficiency of the silicon detector at X-ray energies above 25 keV. We describe how these difficulties can be removed by using semiconductor detectors made from heavier atomic material.

It is well known that there are different preferences in correlated color temperature of light sources for daily living activities or for viewing artistic paintings. There are also data relating the capacity of observers to make judgments on color differences with the spectral power distribution of the light source used. The present work describes a visual color discrimination experiment whose results confirm the existence of a relationship between the correlated color temperature of a light source and the color discrimination capacities of the observers.

Customers preferences are difficult to predict automatically because they are subjective and relative to human likeness patterns which are different from each people. This paper proposes the combination of Interactive Genetic Algorithm (IGA) with Artificial Neural Networks to model the fitness function and find the optimally colored image according to user's preference. As the search space for the IGA is very large, proposed system reduces it creating genotypes with colors restrictions developed with a new graph coloring technique. Two functions are proposed for coding color restrictions. The system presented in this study takes the case of the color design of a building for illustration purposes. Experimental results show that 80% reduction in the number of users evaluations is achieved with proposed combination and speedup in IGA evolution is achieved when color restrictions are coded by proposed mutation and crossover operators.

The color stability of composite resins is a fundamental factor in their clinical behavior. Objective: To evaluate the color stability of composite resins of different colors exposed to a colabased soft drink after different storage periods. Additionally, three methacrylate-based materials and one silorane-based material were evaluated. Material and methods: Specimens of three methacrylatebased materials (Opallis EA3, DA3 and T-Neutral; Filtek Supreme XT A3E, A3D and CT; 4 Seasons A3 Enamel, A3 Dentin and High Value) and one silorane-based material (Filtek P90 A3) were prepared, lightcured for 40 s, and manually polished with Sof-Lex discs. Samples were stored for 1 h, 24 h or 7 days. The color was evaluated by CIE-Lab system before and after immersion for 10 min in a cola-based soft drink. Color variation (∆E) was calculated from individual values of L*, a* and b*, being considered imperceptible when < 1, clinically

Industrial processes create a variety of wastewater pollutants; which are difficult and costly to treat. The present study is under taken to assess the level of physiochemical parameters of the distillery spent wash. These parameters will compare with Bureau of Indian Standards. Untreated effluent is found to have high contents of BOD, and low contents of DO. According to the permissible limit suggested the Bureau of Indian Standards the untreated effluents is toxic to plant so it is not permissible for irrigation. The results reflect that the treated effluents are not highly polluted and they satisfy the Bureau of Indian Standards values and therefore can be used for irrigation purposes.It is one of the most complex, and strongest organic industrial effluent, having extremely high BOD values. Because of the high concentration of organic load. The paper reviews the status of BOD, DO and pH values before and after treatment of the distillery wastewater.

DRAWING IN DRESDEN
Andreas Kempe and Patricia Westerholz from GALERIE URSULA WALTER in Dresden will be showing their selection of my drawings and bringing them together with works by Petra Trenkel and Klaus Walter in their own spatial composition. I won't be there for the opening FRIDAY, 28 FEBRUARY, 6PM, unfortunately. If you get close to the drawing, you'll see my hand and my eye.

Andreas Kempe und Patricia Westerholz der GALERIE URSULA WALTER in Dresden werden ihre Auswahl aus meinen Zeichnungen zeigen und mit Arbeiten von Petra Trenkel und Klaus Walter in einer eigenen Raumkomposition zusammenbringen. Ich bin zur Eröffnung FREITAG, 28. FEBRUAR, 18 UHR​ nicht da, leider, leider. Wenn du nah an die Zeichnung rangehst, siehst du meine Hand und mein Auge.

Sharmin, pre product of Kangdizh, (Persian Color R&D) are scarves measuring 128 by 128 centimeters. The idea for this product became increasingly prominent for me since 2008, when I observed Muslim Malay women in the global modeling scene. This product was manufactured in the summer of 2020 and was showcased in February 2021

شارمین پیش محصول کنگ دژ (نشان طراحی و توسعه رنگ ایرانی) روسری های به قطع ۱۲۸ در ۱۲۸ است، که ایده آن، از دهه ۹۰، زمانی که زنان مسلمان مالایی را درعرصه مدلینگ جهانی می دیدم بیش از پیش برایم پررنگ شد. این محصول در تابستان سال ۱۳۹۹ به تولید رسید و در بهمن ۱۳۹۹ به نمایش در آمد

“Solo il colore e non la forma o la dimensione è oggetto della percezione visiva”
(Galeno, Delle dottrine di Ippocrate e Platone, VII, 7).

Sebbene il colore sia il primo oggetto della vista secondo il pensiero antico, grazie al quale gli oggetti possono essere percepiti nella loro dimensione formale, la sua importanza negli studi archeologici e storico artistici è stata sottovalutata fino al XX secolo.
Le recenti innovazioni scientifiche nella diagnostica dei beni culturali hanno permesso  un incremento qualitativo e quantitativo degli studi sul colore per il periodo classico e tardo medievale. Meno esplorato rimane il periodo di transizione della Tarda Antichità e del primo Medioevo, cruciale per lo sviluppo della storia culturale del colore nelle epoche successive.
Il convegno si propone nella prima giornata di esplorare sotto il profilo cromatico vari supporti della cultura figurativa Tardo Antica per cercare di cogliere l’interazione tra i vari media e l’eventuale sviluppo di una cultura cromatica propria del periodo in esame, in cui le fonti letterarie sottolineano la nascita dell’associazione tra colore e concetto astratto.
Nella seconda giornata si affrontano le problematiche relative alle architetture dipinte, considerando l’evoluzione dello spazio cromatico e della sua percezione attraverso lo studio di una serie di cantieri di scavo, restauro e studio che lo rivelano e lo interpretano.
I due giorni di convegno sono seguiti da una sessione di aggiornamento e di lavoro dei membri del programma di ricerca Colour Concept (COLOUR CONCEPT: the cultural meaning of the Late Antique Polychromies in the West, P.I. Elisabetta Neri, Eu-Next Generation/MUR ) da cui il convegno è promosso.

Noodles are widely consumed around the world, coming in second only to bread in
terms of global consumption. The proper and rational composition of ingredients in
instant noodles allows for calorie reduction, resulting in a healthier product. Okara
being a protein source that is both economical and of excellent quality can be used
in noodles fortification. As a result, research was conducted to formulate and
manufacture okara instant noodles. To optimize the varying levels of components
for noodles, with 14 runs, an I-optimal mixture exploratory design was developed.
The impacts of various recipes, such as okara flour and wheat flour, on the protein,
moisture, ash, and sensory qualities of okara instant noodles were investigated.
Increasing okara flour incorporation greatly enhanced the protein concentration of
noodles. All sensory variables and the overall acceptability had a positive
correlation. The results of the Desirability function confirmed a noodle mixture of
80.178% okara flour and 19.822% wheat flour as optimum

Two surveys were conducted to determine characteristics important in containerized edible flowers that could be sold in retail outlets. Self-selected participants at Bloomfest at Cobo Hall, Detroit, were assigned to one group that rated the importance of attributes such as color of pansy (Viola × × × × ×wittrockiana Gams. 'Accord Banner Clear Mixture'), color combinations, container size, and price. Participants assigned to a second group rated color, color combinations, and container size. Flower color was allocated the most points in the purchasing decision (63% for the first group and 95% for the second), with a mixture of all three colors (blue, yellow, and orange) being the most desirable. Responses were subjected to Cluster Analysis (SPSS Inc., Chicago), which resulted in the formation of three distinct groups. The groups were labeled "Likely Buyer" (those who had eaten and purchased edible flowers before and rated characteristics of edible flowers favorably); "Unlikely Consumer" (those who had eaten edible flowers before and had rated characteristics of edible flowers unfavorably); and "Persuadable Garnishers" (those who had not eaten edible flowers before, but were very likely to purchase edible flowers for a meal's garnish).

WetEarth, a processed recycled newspaper product, was used in combination with pine bark, sand, and vermiculite as a growing medium for rose of Sharon and forsythia. Rose of Sharon was taller and had more leaves; more leaf area per plant; and greater leaf, stem, and root dry weights in all media containing recycled paper compared to plants grown in a medium consisting of 3 pine bark : 1 peat moss : 1 sand (by volume) (control). Forsythia grown in the control media were taller than those grown in any medium containing recycled newspaper. There was no difference in number of leaves per plant or leaf area of forsythia, regardless of growing medium. Physical and chemical properties of each medium also were investigated. All media containing recycled newspaper had a higher pH, porosity, and air space than the control medium.

The objective was to examine the effects of immunocastration on carcass traits and meat quality of Nellore and Nellore x Aberdeen Angus male animals finished in feedlot. Surgically castrated, immunocastrated, and intact animals were finished in feedlot for 90 days. The animals were harvested, and carcass traits were evaluated. Carcasses were chilled, and one 2.5-cm steak was fabricated from Longissimus thoracis muscle. The steaks were individually vacuum packaged and frozen at -18°C. Frozen steaks were thawed, and pH, instrumental color, cooking loss, and shear force were determined. Immunocastrated animals demonstrated greater (P < 0.05) hot dressing percentage and cold dressing percentage than their surgically castrated counterparts. Furthermore, steaks from immunocastrated and surgically castrated animals exhibited greater redness (P < 0.05) and lower darkness (P < 0.05) than steaks from intact animals, indicating possible advantage in retailing. The results suggested that immunocastration may be utilized to improve carcass traits and beef color in feedlot-finished Nellore and Nellore x Aberdeen Angus males.

Dans cette thèse nous examinons le Künstlerroman (le roman de l'artiste) de George Sand en tant que lieu d'un investissement intellectuel complexe qui permet à la romancière à la fois de résoudre une crise identitaire, causée par le statut problématique de femme auteur à son époque, et de mettre en place une axiologie provocatrice qui déstabilise les étalons esthétiques, romanesques et socioculturels contemporains. Nous démontrons, dans un premier temps, comment l'exploitation des structures et des topoï du Künstlerroman dans Lettres d'un voyageur rend possible une représentation (dans la culture) de la Bildung au féminin, phénomène réputé difficile, même impossible dans la littérature du XIX e siècle. Dans un deuxième temps, nous examinons les notions, importantes pour le discours esthétique romantique, de l'idéal, de l'interprétation artistique, telles que les réfracte le Künstlerroman de Sand en les juxtaposant avec la réflexion sur le statut social de l'artiste (de la femme artiste). Une analyse de l'effet-valeur qui se dégage de plusieurs récits représentatifs sandiens (Les maîtres mosaïstes, Pauline, Consuelo, Les maîtres sonneurs) démontre comment la figure de l'artiste, figure créatrice s'il en est une, est utilisée pour produire des récits où de nouvelles significations culturelles apparaissent, de nouvelles relations normatives se forment. Traversé par l'Histoire, mais aspirant à laisser sa propre marque sur elle, le roman de l'artiste sandien met en avant les figures inexistantes dans le roman de l'artiste de ses contemporains : les femmes génies, les paysans artistes, tout en célébrant le savoir-faire des artisans. Au fil de notre étude, nous constatons que son Künstlerroman apporte d'importantes innovations au genre et à celui du iii Bildungsroman, tandis que la romancière supplée à une idéologie romantique de la sacralisation de l'Art et de l'Artiste, tout en valorisant à l'extrême ces deux notions, à l'instar de son époque, ce qu'on pourrait appeler la sécularisation de l'art et de l'artiste.

The application of image processing in the medical field is widely used among medical experts since it can help them by providing an earlier detection and treatment stages. Image enhancement plays an important role in medical images especially in diagnosing a tumor or cancer cells in an image. It will improve the visibility and detail of the image, which can help the expert's diagnosis. The Ki67 is a nuclear protein that was widely used among the pathologists to measure the proliferation of tumour cells. This paper aimed to study the performance of different image enhancement techniques in segmenting Ki67 cells. In this study, the proposed system used three image enhancement techniques, which are contrast stretching, histogram equalization, and CLAHE technique. The enhancement techniques were applied to the colored images. The resultant images then were used as the input images to segment the Ki67 cells. The experimental results show that the contrast stretching technique produced higher results compared to other enhancement types.

В Милане завершилась Неделя дизайна, на которой были представлены 838 брендов. В этом году её посетило рекордное количество зрителей, на 23% больше по сравнению с предыдущим годом. Специально для DEL'ARTE Magazine искусствовед Алёна Григораш героически отстояла во всех итальянских очередях, чтобы рассказать о роли выставки в главных обновлениях дизайна и архитектуры. Как устроена Неделя дизайна Помимо Недели моды ничто так не наводняет Милан публикой, как Неделя дизайна. Гостей и жителей города ждут выставка Salone del Mobile на периферии города и программа Fuorisalone, для которой районы Милана преображаются благодаря различным временным выставочным пространствам. Всю неделю для посетителей мероприятия проводятся различные инсталляции, перформансы, эксклюзивные визиты в исторические палаццо, посольства и частные дома, а также промоакции, безудержные вечеринки и деловые выступления.

Through a narrow crack, like on an old blurry photo, an ancient forum is presented, which is about to crumble into ashes, like an archaeological discovery in contact with fresh air. The architect Davide Bossi and the art historian Alena Grigorash recall their impressions of the exhibition by Alexander and Sasha Brodsky, shown at the Fondazione Galleria Milano (18.03-07.09.2024), especially for the DEL'ARTE Magazine. Architecture "as idea as idea" The exhibition "Piazza senza nome" (Nameless Square) at the Fondazione Galleria Milano is a product of the synergic work of the architect Alexander Brodsky (senior) and his son Sasha Brodsky, who is an engraver. It is a collaboration between two artists (father and son) with different backgrounds, as well as a game of connections and references between a constructed space and paper architectures. Different artworks, but with a common vision, not clear at the first glance, but that invites investigation.

В районе элитного жилья Шелепиха на берегу Москвы-реки, откуда в скором счастливом будущем можно будет легко добраться на электротрамвайчике до выставок интерьерного пространства The Dom, находящихся среди дизайнерских и архитектурных шоурумов, прошла выставка «Археология любви» творческой пары художниц Sisters in Art. В слоях «белого на белом», оттенках чувств и смыслов специально для DEL'ARTE разобралась искусствовед Алёна Григораш. В основу экспозиции положена идеальная «классика» представлений о любви в греческих понятиях. Привычному к гуманитаристике зрителю не бросается в глаза троица «эрос-агапе-филия», но неофит в философии любви удивится, сколь разнообразно называли её греки. К ней добавится и любовь как игралюдус, и отрицательные мания и прагма. Сторге, то есть привязанности, сегодня психологи посвящают целые теории в своих работах о чувствах. Но обо всём по порядку.
