Proximate composition and mineral analysis of Brysocarpus coccineus grass

The proximate and some mineral compositions of Brysocarpus Coccineus in Nigeria were investigated. The grass was found contain 7.56 ± 0.06% moisture, 15.30 ± 0.22% Ash, 7.30 ± 0.26% crude lipid, 4.62 ± 0.11% crude fibre, 3.35 ± 0.22% crude protein, and 61.220 ± 0.90% was determined using standard methods. The mineral content showed 0.06 ± 0.02mg/100g calcium and 0.16 ± 0.08mg/100g magnesium using EDTA titration and 9.28 ± 0.26mg/100g sodium using flame photometer. The results indicated that Brysocarpus Cocccineus is not rich in crude protein, but found to be rich in carbohydrate and total ash content. The higher amount of total ash suggests a high value mineral composition comprising calcium, sodium and magnesium as the main elements. The present study inferred that Brysocarpus Coccineus would not serve as source of protein but a good source of energy. Keywords: Brysocarpus Coccineus , Grass, Mineral analysis, Proximate

> 0.05). Significant differences were received between groups I and II (p = 0.007 < 0.05), II and III groups (p = 0.028 < 0.05). Conclusions: 1) Best bonding properties are characterized on non – contaminated dentin surface by sealers and solvents. Sealer degrades the adhesion of the bonding system; 2) Removed sealer gives better adhesion than uncleaned sealer; 3) Sealer cleaner is able to restore the values of adhesion close to those of uncontaminated dentin surface values.
Fermented Juice of Epiphytic Lactic Acid Bacteria and Molasses Addition on the Fermentation Characteristics and Nutrient Compositions of Sorghum Silage

| This study was conducted to determine the effect of fermented juice of epiphytic lactic acid bacteria (FJLB) and molasses addition on the fermentation characteristics and nutrient compositions of sorghum silage. Sorghums were chopped into pieces of 1-2 cm length and molasses 5% (w/w) and FJLB 1% (v/w) of fresh material were added as silage additives. No significant effects on physical characteristics except pH, lowest in molasses silage, were noted. The higher organic matter and lower fibre contents were observed in molasses silage. Total carbohydrate, non fibre carbohydrate, total digestible nutrients, digestible dry matter and dry matter intake were highest in molasses silage. The higher acetic, propionic and lactic acid concentrations were observed in FJLB silage. The lactic acid bacteria (LAB) count was highest in FJLB silage, and lowest in control silage. The low volatile based nitrogen (VBN) and high V-score, indicators of good quality silages, were generally observed in molasses and FJLB rather than control silages. This experiment indicated that FJLB can be alternatively used as additive instead of using molasses in sorghum silage; however more inclusion level of molasses and FJLB should be used to ensure good quality silage.
Effect of Ginger Rhizomes Extracts on Keeping Quality and Oxidative Stability of UF-White Soft Cheese

The present study was carried out to estimate the effect of ginger rhizomes (Zingiber officinale) extracts on the oxidative stability, chemical composition, microbiological and sensory properties of UF-soft cheese being made with aqueous or ethanolic ginger extracts (1%) compared to control cheese and cheese contained 0.02% of butylated hydroxy anisole (BHA). Resultant cheeses were stored in brine solution 6% at 7±1°C up to 90 days. Results showed that, addition of ginger rhizomes extracts had increasing significant effect (P≤0.05) on fat/DM%, soluble nitrogen (SN/TN%) and non protein nitrogen (NPN/TN%). On the other hand, titratable acidity, total protein%, salt in moisture% and total volatile fatty acids (TVFAs) were decreased with addition of aqueous or ethanolic ginger extracts compared to control cheese and cheese treated with BHA as synthetic antioxidant. Cheese containing 1% ethanolic extract showed the highest oxidative stability. Also, ginger extracts reduced the total bacterial count than the control and BHA treatment. However, yeast and mould counts showed opposite trend and they were not detected in all treated samples up to 60 days of storage. Also, results showed that, cheese samples containing ginger ethanolic extract (1%) showed better organoleptic characteristics than other treatments. From the previous it is advanced to use ginger extract in manufacture of white soft cheese at the rate of (1%).
Identification of phenolic compounds and antioxidant activity of guava dehydrated by different drying methods

Abstract The influence of different drying techniques on guava was investigated, including phenolic components and antioxidant activities. Through drying processes, total phenolic content (TPC) increased and formation of small molecular phenolic acids (multi-methoxy benzoic acid and sinapic acid) was promoted. UPLC-ESI-QTOF-MS determination showed flavanol compounds, hydrolyzable tannins, ellagic acid conjugates and cinnamic acid derivatives were four predominant phenolics of guava. Drying treatments caused degradation of catechin and its derivatives. Contrarily, drying treatments contributed to higher contents of procyanidin trimers. Moreover, thermal drying treatments led to degradation of macromolecular tannins and formation of smaller molecular tannins and ellagic acid conjugates, while simultaneously reduced the stabilities of most intrinsic ellagic acid conjugates. Furthermore, drying processes increased the yield of cinnamic acid dihexose, probably generating from lignin or phenolics–carbohydrate complex. Freeze drying and hot air drying showed better performance on retention of TPC and enhancement of antioxidant activity (AA).
Electrically Tunable Perfect Terahertz Absorber Based on a Graphene Salisbury Screen Hybrid Metasurface

Graphene, as a popular 2D semiconductor, with a carrier concentration that can be extensively tailored by external stimulants, such as electric bias and photoexcitation, is a promising candidate for active optoelectronics. An electrically tunable perfect terahertz absorber is presented by integrating a metallic grating into classical graphene Salisbury screen. The measurement shows that perfect absorption can be achieved for even lightly‐doped graphene and a modulation depth up to 25% is realized. Numerical simulation and analytical model based on the transmission line theory are developed to validate the design, showing a good agreement with the measured results. In addition, dependence of the terahertz response on physical dimensions and polarization of the incident terahertz field is also experimentally explored. It indicates that the hybrid terahertz device is able to function as tunable perfect absorber or tunable polarizer with an extinction ratio up to 23 dB. These results demonstrate the feasibility of using low carrier mobility chemical vapor deposition (CVD) grown graphene for tunable perfect terahertz absorption, which is suitable for potential applications, such as terahertz switching, and time domain and spatial domain modulation.

A steel slag–derived Boudouard reaction catalyst for improved performance of direct carbon solid oxide fuel cells

Solid oxide fuel cells (SOFCs) can directly utilize solid carbon as fuel by integrating with the reverse Boudouard reaction in the anode chamber. Efficiency of the Boudouard gasification of solid carbon fuel is one of the crucial factors influencing the performance of direct carbon SOFCs (DC‐SOFCs). In this paper, a novel Boudouard reaction catalyst derived from steel slag was first introduced into DC‐SOFCs for improving the electrochemical performance. The catalytic activity of the steel slag was activated using the molten alkali method to decompose the inert mineral phases of the raw material. The steel slag–derived catalyst was loaded on the activated charcoal by a wet ball milling method. This kind of catalyst can match up to the readily available solid carbon fuels in cost. Promoted by this highly active Boudouard reaction catalyst, the initial Boudouard gasification temperature of the carbon fuel decreased by 99°C, and the producing rate of carbon monoxide doubled. Furthermore, the power outputs of the fuel cells increased from 91 to 159 mW cm−2, and the fuel utilization increased from 17.10% to 46.43% at 825°C. This study demonstrates that the steel slag–derived catalyst is a promising material for the performance improvement of DC‐SOFCs and may make a valuable contribution to their commercial application.
Scalable Synthesis of Multifunctional Epidermis‐Like Smart Coatings

Bioinspired self‐healing materials provide a sustainable solution for mitigating catastrophic failure and prolonging service time, but such potential may be largely offset by the tedious fabrication process that can hardly be scaled up. It is shown that a scalable doctor blade coating process may be used for the synthesis of multifunctional epidermis‐like smart coatings. The industry‐compatible technique not only preserves the biomimetic bilayer design with largely improved film production efficiency but also allows readily adjusted film compositions and structures for optimizing the synergetic healing performance and mechanical properties. Variable amounts of montmorillonite clay nanosheets can be incorporated in the top hard layer for achieving a high modulus (34.3 ± 1.4 GPa) and hardness (1.65 ± 0.09 GPa), which also affect the number of scratch‐healing cycles by controlling the decay rate of upward polymer diffusion from the soft bottom layer. These high‐performance smart coatings are transparent, bactericidal, and show good adhesions to various substrates including glass, plastics, and fiberboard. When used as a surface protection for fiberboard, excellent flame‐retardant properties are demonstrated thanks to the dominant presence of clay nanosheets. It is believed that this work may provide important guidance for transforming interesting biomimetic design into practical manufacturing.
Scaling learning algorithms using locality sensitive hashing

With increasing volumes of data, it is imperative that data analysis can appropriately scale. However, many common machine learning algorithms, e.g., metric learning, manifold landmark learning, and processing trajectories, suffer poor computational complexity in the size of training data. In this thesis, we propose generic methods for scaling up learning algorithms by utilizing locality sensitive hashing. First, finding representative samples utilizing locality sensitive hashing is proposed. The usefulness of these samples is demonstrated on large-scale supervised metric learning. Our methods achieve quadratic speed up with only minimal decrease in accuracy. Second, representative samples are leveraged for adaptive minibatch selection for fitting Gaussian processes for landmarking manifolds. Our methods exploit the compatibility of locality sensitive hashing and the manifold assumption in high-dimensional data, thereby limiting expensive optimization to relevant regions of the data. Training the state-of-the-art learner with our compressed dataset achieves superior accuracy compared to training with randomly selected samples. We also demonstrate that our methods can be used to find manifold landmarks without learning Gaussian processes at all, which leads to orders-of-magnitude speed up with only minimal decrease in accuracy. And finally, we propose locality sensitive hashing based feature hashing methods which map variable length trajectories to constant length trajectories for efficient similarity computation in Euclidean space. Our methods can accelerate trajectory clustering while achieving competitive accuracy in comparison to clustering using more complicated distance function, such as Dynamic Time Warping.

Improving reproductive efficiency through the supplementation of mustard oil, poly-herbal mixture and butyric acid during the periparturient period in sahiwal cows

Periparturient period is a challenging time for dairy cattle as the cows have to deal with physiological, metabolic and endocrine changes along with environment and management related stresses. Present study was conducted to know the effect of mustard oil, butyrate and polyherbal mixture supplementation on productive and reproductive performance of Sahiwal cows. For this 20 multiparous Sahiwal cows were selected and divided into two equal groups according to their EPA. The cows were fed with scheduled NDRI ration but in addition, cows of treatment group were fed mustard oil (200 ml/day) and polyherbal mixture (150g/day) 30 days before and after parturition whereas butyrate (200g/day) was fed 30 days post-partum and decoction for 7days postpartum. Blood sampling was done on 28th, 21st, 14th, 7th and 3rd day prepartum, on the day of calving and 3rd, 7th, 14th, 21st and 28th day postpartum. Ultrasonography of uterus to see the uterine involution was done up to 42 days postpartum in weekly interval. The mean NEFA values were significantly (P<0.05) lower in supplemented group as compare to control group. The average value of uterine diameter and cervical diameter during postpartum period was significantly (P<0.05) lower in supplemented group than control group. There were 20% cases of RFM in control group whereas in supplemented group there were no cases of RFM. The time taken for expulsion of fetal was significantly (P<0.05) lower in supplemented group. Days to 1st observed heat were significantly less in supplemented (P<0.05) group. Birth weight of calf was significantly higher in supplemented group. Conception rate was higher in supplemented group. The mean days to 1st service was significantly (P<0.05) lower in treatment cows as compare to control group. The results of the study help to conclude that the supplementation was helpful for maintaining overall reproductive efficiency by improving reproductive health.
Ligand Effect on Iron‐Catalyzed Cross‐Coupling Reactions: Evaluation of Amides as O‐Coordinating Ligands

The development of new highly efficient O‐coordinating ligands for iron‐catalyzed C(sp2)−C(sp3) cross‐coupling reactions is reported. A structure‐reactivity study on the effect of amides as ligands in the industrially‐important iron‐catalyzed cross‐coupling of aryl chlorides with challenging organometallics possessing β‐hydrogens was performed. Investigation of a series of new 21 ligands that rationally vary in O‐coordination aptitude as well as sterics around the amide bond pinpointed the features that are important for catalysis. The study led to the discovery of several highly efficient ligands for cross‐coupling, including TMU (TMU=tetramethylurea), N‐cyclic and coordinating benzamides. Crucially, the study demonstrates several avenues for replacing reprotoxic NMP, which is currently still the most common additive in industrial applications of sustainable iron‐catalyzed cross‐coupling chemistry.
Effect of Adsorption on Degradation of the Pesticide Aldicarb in the Soil

Chemical and microbial degradation of the pesticide aldicarb has been studied extensively in both laboratory and field. These studies exhibit that temperature and porosity are important factors affecting the degradation of aldicarb and its daughter product sulfoxide in the soil. Since microbial activity decreases with depth, chemical processes are important component of the degradation of the aldicarb. The rate of degradation is faster in the liquid state than the sorbed state. Sorption reduces the bioavailability of the chemical and is inversely related to porosity. Hence, rate of degradation of the aldicarb and the daughter product sulfoxide is inversely related to the porosity

THE PROBLEMS OF MEAT PRODUCTS THERMAL TREATMENT

The main problems of meat products thermal treatment have been considered and analysed in the paper. Analysis of the existing research papers suggests that the main attention is devoted to the influence of temperature value and time of processing on the physical, chemical, microbiological and organoleptic indicators of the product. The influence on the protein and fat components of raw meat has been described as well as the changes in the meat product structure under the influence of temperature have been pointed out. The important impact of thermal treatment on the changes in proteins at heating, including solubility and hydration of the proteins, has been examined. The paper analyses the microbiota screening before and after thermal treatment. Special attention was paid to the impact of temperature on microbiota as it is an important indicator of a meat product safety. Methods and purpose of thermal treatments as well as the advantages and drawbacks of each method were considered. Formation of tastiness properties of the product depending on the methods and thermal cycling was emphasized. Submitted is the analysis of the factors that influence the product mass losses under the impact of high temperature. The dependence conditions of a meat product quality on the thermal cycle were also analysed. Attention is paid to alternative methods of thermal heating as well as their influence on ready product quality and safety. Substantial contribution of Odesa National Academy of Food Technologies to solving problems of the conventional thermal treatment of meat products was shown, same as a possibility of bringing a product to cooking readiness without application of high temperature. The main content of the paper includes analysis of the methods and thermal treatment cycles existing in the world and proves importance of the temperature control and cooking time which influence safety, quality and yield of the product.

Temperature-dependent photoconductive properties of Ge-Sb-Te thin films

ABSTRACT The present paper reports the study of photoconductive properties viz. steady state photoconductivity, dark conductivity , dark activation energy , transient photoconductivity on vacuum evaporated thin films of Ge20Te80-xSbx (x = 0, 2, 4, 6, 10 at. %). At higher concentration of antimony, dark activation energy is found to decrease. A similar trend in the optical band gap is also observed. Optical band gap also decreases with the addition of antimony in the system. This drop in activation energy points towards an increase in the density of defect states in the system. Dark conductivity values are found to increase, and this rise is due to an increase in polarizability of antimony and partial ionic behaviour of the system. Photosensitivity decreases with an increase in the antimony content in the matrix. Photocurrent versus light intensity follows the power law and predominance of bimolecular recombination is found. During transient measurements, the decay rate is found to be non-exponential. A differential lifetime is found to increase with the addition of antimony as a dopant. The study of the decay of photocurrent reveals relaxation processes in the present chalcogenide glassy matrix. This behaviour indicates a slow decay process due to the increase in the density of defect state in the mobility gap. Similar results are also confirmed with an increase in the carrier concentration.
Dicaffeoylquinic Acids from the Aerial Parts of Artemisia ciniformis Krasch. & Popov ex Poljakov

Background: Artemisia ciniformis (A. ciniformis) belongs to the genus Artemisia and grows at northeast of Iran. The current phytochemical study was carried out on the most potent extract in cell-free antioxidant assays. Methods: Hydroethanolic extract of the aerial parts was fractionated using vacuum-liquid chromatography (VLC). The selected fraction from the previous cell-free antioxidant study was purified by semi-preparative HPLC. The structures of isolated compounds were identified using one- and two-dimensional NMR and ESIMS techniques. Results: Three identified compounds in this study were the known isomers of dicaffeoylquinic acid (DCQ), including 3,5- DCQ (isochlorogenic acid A), 3,4-DCQ (isochlorogenic acid B) and 4,5-DCQ (isochlorogenic acid C). Conclusion: The outstanding free radical scavenging potential in the hydroethanolic extract of A. ciniformis might be partly related to the presence of isochlorogenic acid derivatives.
