Abstract The present study was dealt with the estimation of the chemical composition (moisture, protein, fat, and ash) and physical properties (pH and water holding capacity) of camel, duck, and tuna meat purchased from local markets. Muscle proteins were separated, including myofibril and sarcoplasmic proteins from these meats, estimation of the yield and study of their content. have been studied. the results were as follows: 1. Statistical results disclosed that there was a significant difference at a probability level (P≤0.05) in the percentage of moisture, protein, fat, ash, pH, and values of water holding capability in each of camel, duck, and tuna's meat. 2. Statistical results made a clear reference that there were significant differences at a probability level (P≤0.05) in the percentage of yield, moisture, protein, fat, and ash of myofibril and sarcoplasmic proteins in each of camel, duck, and tuna's meat. Also, a dual interference between meat type and protein type was significant in its impact on percentages of yield and chemical composition. 3. It was observed the percentage of moisture and fat in tuna meat was higher than the percentage of moisture in duck meat. As to the lowest percentage of moisture, it was in the meat of tuna, while the tuna meat recorded the highest percentage in protein and ash, then followed by the percentage of protein and ash in duck meat, while camel's meat recorded the lowest percentage of protein and ash. Besides, results indicated that the values of pH and water holding capability of duck meat were higher than that in the meat of tuna meat and camel. 4. It was found that the percentage of the yield for proteins of a myofibril of duck meat was higher than that in the meat of tuna and camels, as the percentage of yield of sarcoplasmic proteins for tuna was higher than that in the meat of duck and camels. 5. It was found that the percentage of yield for myofibril of duck meat was higher than that in the meat of tuna and camels. As to the percentage of yield for sarcoplasmic proteins of tuna meat, it was higher than that in the meat of duck and camels. 6. The highest percentage of moisture for myofibril proteins was in the meat of camels, and the lowest percentage of it was registered in myofibril proteins in tuna meat, whilst the highest percentage of moisture for sarcoplasmic proteins was registered in the meat of duck, and the lowest of it registered in sarcoplasmic proteins in tuna meat. 7. It was observed that the highest percentage of protein and fat for myofibril and sarcoplasmic proteins was registered in tuna meat, as the lowest percentage of protein and fat for myofibril and sarcoplasmic proteins were observed in duck meat. 8. The study came up with a result revealing that the percentage of ash in proteins of myofibril proteins for duck meat was higher than that in myofibril proteins for camels and tuna meat, whilst, the percentage of ash in sarcoplasmic proteins for camel meat was higher than that in sarcoplasmic proteins for duck and tuna meat. 9. Results showed that the highest concentration of sarcoplasmic proteins was in tuna meat, followed by duck meat, and the lowest concentration for these proteins was in camel meat.

The effect of the addition of three types of tropical edible seaweeds, Kappaphycus alvarezii (KA), Sargassum polycystum (SP), and Caulerpa lentilifira (CL), on sausages were studied. Nine sausage formulations with three levels of inclusion (2%, 4%, and 6%) of each seaweed were prepared, analysed, and compared with the control sample (without seaweed) in terms of their physicochemical properties, total phenolic content, and lipid oxidation. The modified sausages had low moisture and fat content (p < 0.05) but high ash and dietary fiber content (p < 0.05) compared to the control sausage. The addition of seaweed powder changed the texture of the sausages, mainly its hardness and chewiness (p < 0.05), but no significant difference in cohesiveness and springiness was found (p < 0.05). The modified sausages were shown to have high water holding capacities and cooking yields. The different types of seaweed modified the colour of the chicken sausages differently. In general, the L* (brightness) and b* (yellowness) values was low for all sausage samples containing seaweed powder (p < 0.05), while the a* (redness) value increased with the addition of the KA and SP seaweed powder but decreased for the sausage sample with added CL seaweed powder (p < 0.05). Moreover, the modified sausages have higher total phenolic contents and high antioxidant capacities, which contributed to slowing the oxidation of lipid in sausages during storage (p < 0.05). Sensory evaluation showed that the panellists found up to 4% of KA and 2% of SP to be acceptable. Overall, the seaweeds, especially KA and SP, could potentially be developed as excellent additives for the manufacture of highly technological high-quality meat products.

The objective of this study was to determine differences in relevant parameters of the basic chemical composition of flesh (descriptors: dry matter &ndash; DM, crude proteins &ndash; CP, net proteins &ndash; NP and net muscle proteins &ndash; NMP, fat &ndash; F, ash &ndash; A) of communal stock of diploid (2n) and triploid (3n) tench (Tinca tinca L.) of the same origin, in relation to sex (F: female vs. M: male) and age (T<sub>3</sub>: 36 months, after overwintering vs. T<sub>3+</sub>: 42&nbsp;months, after one summer in the pond). Altogether 137 siblings of tench were studied. The basic chemical composition of flesh of 2n and 3n tench of T<sub>3</sub> age was found to be nearly the same. The only significant difference (P &lt; 0.05) was found in DM content in diploids (5.7% higher DM content in females). Marked changes in the basic chemical composition were related to the increasing age of tench: after one summer in the pond (from T<sub>3</sub> to T<sub>3+</sub>) the DM content increased significantly in all groups of tench (by 5.4% in 2n females, P &lt; 0.05; by 6.5% in 2n males, 9.9% in 3n females and by 7.4% in 3n males, all at P &lt; 0.01). The content of nitrogenous substances was found to increase significantly (P &lt; 0.01) in flesh of 2n males: CP by 3.2%, NP by 4.2% and NMP by 3.3% and in flesh of 3n males: CP by 7.0%, NP by 6.6% and NMP by 7.3%. Muscles of 3n females contained 107.3% higher fat content (P &lt; 0.05). The proportion of ash decreased in 2n and 3n by 2.5% and 1.7%, respectively (P &lt; 0.05). The flesh quality of T<sub>3+ </sub>tench after one summer in the pond was higher if compared with that of T<sub>3 </sub>tench after overwintering. Related to the ploidy level, more favourable chemical composition of flesh and more favourable flesh quality were found for triploids of T<sub>3+</sub> age. &nbsp;

Abstract. The aim of the present research was to study the chemical composition, technological traits and intensity of boar taint of meat in entire male (EM) and surgically castrated male (CM) pigs. The study included 46 male pigs, cross F1 (Landrace x Danube White), fattened to average live weight 90 kg. In terms of chemical composition, the higher water and lipid content of the meat of entire male pigs, compared to the meat of surgically castrated male pigs was not statistically significant. A significant difference in the meat’s technological traits – pH values, water-holding capacity, cooking losses and tenderness between the two groups of male animals ware not found. The influence of the factor “castration” was reported in trait marbling of meat (p<0.001). There were statistically significant differences in the values of L*, b* and Hue angle, defining the color characteristics of the meat.

This study uses Pakistan Social and Living Measurement Survey 2016 to study gender discrimination in school enrollment across the four provinces of Pakistan using bi-variate analysis. Results show that there is highly significant difference between male and female education in rural areas (x^2=4940.50 and p<0.05). Analysis indicate that gender disparity in enrollment is significantly higher in low income households (x^2=115.468 and P<0.05). The study also showed that as compared to male, fewer female are enrolled in both public and private sectors. Hence, socio-economic factors play important role in making decision about children enrollment in different types of school. The study recommends that government to take appropriate steps to reduce gender discrimination in school enrollment by offering subsidy on female education in the country.

This paper presents an intensive procedure used for the decontamination of the soils, which were radioactively contaminated by uranium, due to the occurrence of some antropic accidents, in order to limit the area�s pollution. The procedure used for the chemical decontamination of the polluted soils was the washing one and the decontamination degree is comparatively presented depending on the ultrasounds� presence and absence. The lab testes were performed on five types of soils , which were characterized from the granulometric, structural and chemical composition viewpoint, all these aspects represent the main factors, which determine the applied decontamination procedure�s limits and performances correlated with its utilization costs. The decontamination procedure�s kinetics for each type of soils was analyzed, using successively three different types of reagents (water, 0.1 M sulphuric acid solution and chloro-sodic solution � 100 g/L sodium chloride + 10 g/L sodium carbonate in water) for a solid to liquid ratio of 1:2, during 2 h, at a temperature of 20oC in a mechanic stirring system respectively in ultrasounds field. It was observed that the decontamination degree increases with up to 15-20% in case of the ultrasound field utilization comparing to the first case.

Total twenty different processed meat plant producing emulsion type sausage were histologically and chemically examined for detection of adulteration with unauthorized tissues. Results revealed that samples were adulterated with different types of animal tissues included; hyaline cartilage, tendon, spongy bone, peripheral nerve trunk, basophilic matrix, lymphatic tissue, fascia, fibrocartilage and vascular tissue. Moreover, these samples were adulterated Also, adulterated with plant tissue included; plant stem, leaves and root. Chemical analysis showed a significant difference in their chemical composition (moisture, fat, protein, ash and calcium) content. Moisture and fat content varied around the permissible limit of E.S.S. while low protein, high ash and calcium content was detected in the examined samples. Therefore, Histological and chemical examinations can be used as reliable methods to detect adultration using unauthorized addition of both animal and plant tissues in processed meat product samples which revealed a high level of falsification.

Abstract Objective Snails secrete different types of mucus that serve several functions, and are increasingly being exploited for medical and cosmetic applications. In this study, we explored the protein pattern and compared the biological properties of the mucus secreted from the mantle collar and foot of two snail species, Lissachatina fulica and Hemiplecta distincta. Result Protein profile showed a different pattern between the two species and between the two secretory parts. The mantle-specific protein bands were further characterized and among them was an antibacterial protein, achacin. Accordingly, the mucus from the mantle exhibited the higher antibacterial activity than that from the foot in both snail species. The mucus from H. distincta, first reported here, also showed antibacterial properties, but with a lower activity compared to that for L. fulica. Snail mucus also exhibited anti-tyrosinase activity and antioxidant activity but with no significant difference between the foot and mantle mucus. These results indicate some different protein compositions and biological activities of snail slime from the mantle and foot, which might be associated with their specific functions in the animal and are useful for medical applications.

The parents of children with dyslexia often experience more parenting stress and depressive symptoms compared to other parents. Studies have shown that supporting and encouraging such parents help in reducing their frustrations, fear, anger, and low self-esteem towards their children. The purpose of this study was to identify and examine the different types of support needed by the parents of children with dyslexia and to explore the relationships between the required support with the parents’ marital status. Fifty questionnaires were distributed to the parents of children with dyslexia and analyzed. The findings showed that the type of support needed for parents of children with dyslexia could be grouped into social, peer-to-peer, financial, and government support. Furthermore, the analysis indicated that there were no significant differences between the social (p = 0.4014), peer-to-peer (p = 0.5020), and government (p = 0.7121) support with parents’ marital status. However, based on one-way ANOVA analysis, there was a significant difference found between the parents’ marital status and financial support (p = 0.0241). Accordingly, it is anticipated that the implication of this research could be used as a guide and a reference for supporting and encouraging parents of children with dyslexia and other learning disabilities.

This work presents a comparison of two inocula used for the acclimation of two anaerobic-aerobic sequencing batch bioreactors used for toxic wastewater treatment. The bioreactors were acclimated with different types of sludge: one coming from an anaerobic wastewater treatment plant and the other one from a conventional aerobic activated sludge plant. The model toxic compound was p-nitrophenol, which is reduced to p-aminophenol during the initial anaerobic phase of the reaction, and later mineralized during a posterior aerated reaction phase. Biodegradation of the compounds was monitored using UV/Vis spectrophotometry. After acclimation stabilization of the sludge and of the process was also monitored. Results show that there is no significant difference in acclimation times and stability of the process between the two employed inocula, and thus an originally anaerobic inoculum presents no apparent advantage over a more easily accessible aerobic one.
