    The study aimed to draw attention to the camel's hair available in Afif province and to give information about their physical and chemical properties, and improve their properties. The researchers' collected 50 samples of camel's hair, analyze, and then add improvement material. The study concluded that the Afif Province camel's hair have properties that can converted into textile materials. The softness are from 24.5 to 29 μ, (B and C1) according to the classification of the German system GER, and between 58 S And 60 S according to the classification of (USA, AUS, GRB). The thickness between 5.3 - 12 cn/ tex. The length between (3.8 - 25.5 cm), and the colors of camels hair (Brown, light brown, light creamy, dark creamy). The chemical properties were similar to the global chemical properties of wool, Absorption of moisture from 0.10% to 0.26%, the protein content from 52% to 95%, and its capable temperature to 140 °C without occur softness or fusion, and after 140 degree centigrade the decomposition occurs. Characteristics of the camel's hair can improve by adding some chemicals, such as acetic acid to improve the softness without affecting the durability, or by mixed with other fiber.

Polyphenols are the secondary metabolites of plants and has an important role in human nutrition as the leading antioxidants. According to the carbon number-based classification of polyphenols, resveratrol is a natural polyphenol in the stilbene group with antioxidant and anticarcinogenic effects. Its beneficial effects on cardiovascular diseases have also been reported. It was first identified in 1940 and has recently gained importance especially in medicine and pharmacy. Researchers have carried out various studies on resveratrol and its time-honored use in traditional eastern medicine has been reported. Resveratrol is a food ingredient that has the potential to be used in the treatment of various diseases, but also has antiviral effects. The study focuses on resveratrol’s physical and chemical properties, effects on health, antiviral effects and use in foods as a functional component.

Chikuwa is one of Japanese traditional fishery food product that commonly made from potato starch, fish surimi, and some spices. To enhance Chikuwa physical and chemical properties especially in texture attribute and protein content, Gelatin can be added. Gelatin is a partial hydrolysis protein that usually added in food making process to improve the gumminess quality and the protein content. Gelatin can be derived from bone collagen, skin and fish scale. The purpose of this study is to analyze the effect of gelatin from various skin fish to the physical and chemical characteristics of Chikuwa. The research method used is experimental laboratories using a completely randomized design (CRD) with 3 replications. The data analysed with ANOVA and continued with BNJ analysis if there is a significant difference between the treatments. This research has divided into two stages. The first step aim is to make the gelatin from the skin of seabass, payus fish and tilapia with 3% concentrations. The second step is Chikuwa making added with gelatin. The parameters that observed are water content, protein content, white degree, gel strength, sensory attributes, folding, bite. The results showed that Chikuwa with the addition of gelatin from seabass, payus and tilapia skin are significantly different (p <0.05) due to the physical and chemical characteristics of Chikuwa. The best Chikuwa quality is Chikuwa with the addition of seabass gelatin, where the gelatin yield is 18.03 ± 0.68; the gelatin gel strength is 251.11 ± 1.08 bloom; the viscosity is 5.80 ± 0.15 cP; the gel Chikuwa sample strength is 954.54 ± 0.56 gcm and protein content is 22.01 ± 0.98%

A common toposequence on Bunya Phyllite in south-east Queensland was studied in detail at a representative site. Four sample profiles on the slope are described, and some physical and chemical properties are given. The clay minerals, derived from the weathering of the quartz-sericite-chlorite phyllite, comprise dioctahedral mica, dioctahedral vermiculite, an interstratification of these minerals, and kaolin. Properties are related to the slope; and the clay-rich horizon of the middle and lower slopes is considered to be formed mostly by in situ weathering. The classification of the genetic unit given by the slope and parent material is discussed.

The physical and chemical properties of nanofluorocarbon-based magnetic fluids are deeply affected by the introduction of fluorinated base liquid. In this paper, firstly we introduce the concept, composition and classification of nanofluorocarbon-based magnetic fluids, then we discuss the properties, preparation and structure of perfluoro polyethers (PFPE); afterwards we analyze the NMR spectrum to infer the structure contained in the polymer in detail and systematically, further verify the functional group of PFPE.

Crambe seeds have numerous industrial applications. Crambe seed oil contains mostly monounsaturated fatty acids. Seeds contain crude protein, amino acid, glucosinolates. They are used in human and animal nutrition. The aim of this study was to determine the physical and chemical properties of crambe seeds subjected to fertilization at 0, 15, 30 kg S ha−1. Thousand seed weight ranged from 6.93 g (0S) to 8.04 g (30S). All results were statistically significantly different. Length (L) of seeds ranged from 2.20 mm (0S, 15S) to 2.24 mm (30S), width (S) ranged from 1.90 mm (0S) to 1.95 mm (30S), surface area (F) ranged from 3.53 mm2 (0S) to 3.67 mm2 (30S). All samples (0S, 15S, 30S) formed one homogenous group for the values of L, S, F. Crude fat content was 349.8 g kg−1 DM (0S) to 377.9 g kg−1 DM (30S) and crude protein content was 241.0 g kg−1 DM (0S) to 250.3 g kg−1 DM (30S). The results for each sample were statistically significantly different. The results can be used in practice to determine the dose of sulfur fertilizer. Fertilization caused changes in 1000 seed weight of crambe. Additionally, selected linear dimensions and shape factors of crambe seeds were affected by fertilizer. Sulfur fertilization caused changes in the crude fat and crude protein content of crambe seeds.

Three representative soil pedonsof northern hills of Chhattisgarh, M.P were morphologically studied, characterized and classified. The soils are very deep, colour ranges from brown (10YR5/3) to dark brown (10YR3/3) and very dark greyish brown (10YR3/2) in different horizons. Fe and calcretes are observed in sub surface horizons. The texture in surface soils varied from clay loam to clay while in pedon 2, the texture was observed sandy clay loam throughout the profile. The soils are calcareous and pH ranged from 7.0 to 7.5. The organic carbon content in these soils were (4.4 g kg-1), low to medium (6.1 g kg-1) in surface and decreased with depth. Cation exchange capacity (CEC) were found high in horizons where clay content was more. Based on morphological, physical and chemical properties P1 and P3 were classified as VerticHaplustalfs and pedon (P2) was placed under Typic Haplustepts.

AbstractBiofluorescence has been detected in several nocturnal-crepuscular organisms from invertebrates to birds and mammals. Biofluorescence in mammals has been detected across the phylogeny, including the monotreme duck-billed platypus (Ornithorhyncus anatinus), marsupial opossums (Didelphidae), and New World placental flying squirrels (Gluacomys spp.). Here, we document vivid biofluorescence of springhare (Pedetidae) in both museum specimens and captive individuals—the first documented biofluorescence of an Old World placental mammal. We explore the variation in biofluorescence across our sample and characterize its physical and chemical properties. The striking visual patterning and intensity of color shift was unique relative to biofluorescence found in other mammals. We establish that biofluorescence in springhare likely originates within the cuticle of the hair fiber and emanates, at least partially, from several fluorescent porphyrins and potentially one unassigned molecule absent from our standard porphyrin mixture. This discovery further supports the hypothesis that biofluorescence may be ecologically important for nocturnal-crepuscular mammals and suggests that it may be more broadly distributed throughout Mammalia than previously thought.
