Salmonellas, Poultry House Environments and Feeds: A Review
A. Frederick,N. Huda
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2011.679.685
Abstract: The gram-negative bacteria and member of the family Enterobacteraceae is one of the most important causes of human food-borne illnesses in recent times. These pathogens may occur naturally in the gastrointestinal tract of poultry and sometimes in eggs through transovarian transmission. A number of factors have contributed to the spread of Salmonella in poultry. Among these are stocking densities of poultry farms, poultry feeds, farming activities, mice, wild animals, transportation of live birds to slaughter houses, slaughtering of live birds and processing of poultry carcasses into processed finished products. Lesser concerned area is the association between Salmonellas, poultry house environments and feeds and the significant role they may play to integrate other factors in contributing to the spread of Salmonella in poultry. Furthermore, techniques for isolating and identifying Salmonella species in poultry house environments and feeds are crucial for reliable reporting purposes to reduce the spread of Salmonella by poultry thus the objective of this study.
Effects of Post-Slaughter Carcass Handling on Meat Quality
F. Adzitey§ and N. Huda*
Pakistan Veterinary Journal , 2012,
Abstract: The quality of meat from the processing plant or as found on the market will have an influence on its processing properties and eating qualities. The processing properties and eating qualities will also influence consumers’ acceptability and profits to be realized by producers, processors and retailers. A number of factors including the genetics of the animal, production practices, age of the animal at slaughter and how live animals are handle prior to and during slaughter contribute significantly to meat quality. Apart from these, post-slaughter practices also influence meat quality to an appreciable extent. In recent times, various processing conditions and addition of ingredients/additives have been manipulated to improve upon the quality of processed meat products. This mini-review discusses the effects of post-slaughter practices on meat quality.
Assessment of Osteoporosis in Post Menopausal Women: A Clinical Study
R Najam,N Huda
Nepal Journal of Obstetrics and Gynaecology , 2011, DOI: 10.3126/njog.v6i2.6749
Abstract: Aims: Osteoporosis is a metabolic disorder of the bones that is characterized by decreased bone density which predisposes to increased fracture risk. The disease can exist undiagnosed for a long time as it produces no distinct symptoms and is detected when a fracture has already occurred. There is sufficient evidence to state that the risk of osteoporosis and fracture increases with age and after menopause, that bone density measurements accurately predict the risk for fractures in the short-term, and that treating asymptomatic women with osteoporosis reduces their risk for fracture. The present cross sectional study was undertaken to assess osteoporosis in postmenopausal women by measuring bone mineral density (BMD). Methods: This is a prospective study, conducted at the Department of Obstetrics and Gynecology, Teerthanker Mahaveer Medical College, Moradabad. India. Post menopausal women were included in the study. Women who had undergone hysterectomy or who were on hormone replacement therapy or calcium or vitamin D preparations were excluded from the study. The participants underwent BMD measurement by Achilles Ultrasound bone densitometer. The results of BMD were analysed on the basis of T-Scores and were represented in the form of a graph. Results: Of the 90 patients that were included in the study 42.2 %( n=38) were in the age group of 45-55years. In almost 50% of patients the duration of menopause was 6-10 years. Of the 90 patients 10%(n=9)were normal, 44.4%(n=40) were osteopenic, 33.3%(n=30) were osteoporotic and 12.2%(n=11) were severely osteoporotic. Backache was the commonest presenting symptom in the study population. Conclusions: Quantitative ultrasound (QUS) is a rapid and inexpensive method of measuring bone density. In our study 90% of the postmenopausal women had subnormal T scores. We recommend regular BMD measurements in postmenopausal subjects for early diagnosis and treatment of osteoporosis in this vulnerable group.

World Journal of Nuclear Science and Technology (WJNST) , 2017, DOI: 10.4236/wjnst.2017.73013
Abstract: A design for instantaneous neutron flux signal acquisition system is being carried out for reactivity measurement of the nuclear research reactor. It is a computer-based digital data acquisition system that can perform continuous monitor and measurement of reactivity inserted into or removed from the research reactor. The acquisition system accomplishes with two major parts. The first part is an interfacing PCI based data acquisition card and the corresponding driver software intending to on-line acquisition of neutron flux signals from plant instrumentation channel. The second part incorporates the high-level Visual Basic real time program, indigenously developed for computation of reactivity by the solution of neutron point kinetic equations and other relevant functional modules like input file logging, reactivity calculation, graphics demonstration etc.
Insulin-Like Growth Factor-1 and Osteocalcin Are Correlated with Markers of Osteoporosis in Postmenopausal Women with Type-2 Diabetes  [PDF]
Maher A. Kamel, Madiha H. Helmy, Anna N. Abou Rayah, Nevine Mohannad, Huda M. N. Hania
Open Journal of Endocrine and Metabolic Diseases (OJEMD) , 2013, DOI: 10.4236/ojemd.2013.35033
Abstract:

Objective: The study was conducted to evaluate the relation between insulin-like growth factor-1 and osteocalcin and markers of bone modulation (osteoprotegerin; OPG, receptor activator nuclear kappa B; RANK and RANK ligand; RANKL) in postmenopausal Type 2 diabetic women with and without osteoporosis. Methods: The study was conducted on 90 female divided into three groups (30 each). Group I included healthy postmenopausal women as a control, Group II included diabetic postmenopausal women without osteoporosis Group III included diabetic postmenopausal women with osteoporosis. Fasting blood samples were obtained for the determination of blood glucose, HbA1c, total and ionized calcium, OPG, RANK and RANKL. Also the levels of IGF-1 and osteocalcin were assessed. Results: In postmenopausal Type 2 diabetic women, the osteoporosis resulted in derangement in OPG/sRANKL system. The serum level of OPG was elevated while sRANKL declines in osteoporotic postmenopausal Type 2 diabetic women. IGF-1 level decreased in diabetic postmenopausal women but those women with osteoporosis showed a great decline by about 60%. IGF-1 level in osteoporotic diabetic postmenopausal women was correlated with BMD and most bone turnover markers (OPG, sRANKL, OPG/sRANKL). Osteocalcin declined significantly only in those women with osteoporosis not without osteoporosis. Conclusions: The circulating levels of OPG and sRANKL were not useful markers for bone status in postmenopausal women while the circulating levels of IGF-1 and osteocalcin might give useful information about bone status in postmenopausal diabetic women.

Microwave Separation of Water-In-Crude Oil Emulsions
Huda S. N.,Nour A. H.
International Journal of Chemical and Environmental Engineering , 2011,
Abstract: Formation of emulsions during oil production is a costly problem, both in terms of chemicals used and due to production losses. For economic purpose, pipeline consideration and for efficient refinery operations, the produced emulsions must dewatered and necessary to separate the water completely from the crude oils before transporting them. The objectives of this study was to study crude oil emulsions stability using different volume ratio of water-oil and different types of crude oils as well as to examine the performance of microwave application in demulsification of water-in-crude oil emulsions in comparison to the conventional methods. Two types of crude oils with three volume ratios of water-oil 50-50%, 30-70% and 20-80% (w/o) were used and a type of surfactant was SDDS. Two different microwave powers of 180 watt and 720 watt were used. This study revealed that the stability of the water-in-oil emulsion stabilized by ionic surfactant increases as the surfactant concentration increased. Increasing the oil content of the emulsion resulted in increased emulsion stability. In terms of demulsification, microwave heating technology can be an alternative method for breaking water-oil emulsion. Microwave heating technology does not required chemical addition.

B. Ikhlas,N. Huda,I. Noryati
International Journal of Poultry Science , 2011,
Abstract: Quail meatballs using different types of flour were analyzed for their proximate composition (moisture, protein, fat, ash and total carbohydrate) and physicochemical properties (cooking yield, moisture retention, fat retention, juiciness, folding test, color, texture profile analysis and sensory qualities). Meatballs were produced using 65% quail meat, 3% flour (cassava, corn, wheat, sago and potato flour), 3.2% soy protein isolate, 10% palm oil, 2.1% salt, 2% sugar, 0.9% mixed spices and 13.8% cool water. The proximate composition of the quail meatballs produced was comprised of 64.94-66.33% moisture, 13.43-14.47% protein, 10.32-13.77% fat, 2.30-2.95% ash and 4.80-7.67% carbohydrates. The cooking yield was highest for the quail meatball formulation using potato flour (98.97%), followed by the yields of formulations using, cassava (97.99%), sago (97.46%), corn (91.06%) and wheat flour (91.00%). Folding test scores were in the range of 3.50-4.67. Lightness (L*) was in the range of 66.06-69.10, redness (a*) was in the range of 1.79-2.25 and yellowness (b*) was in the range of 17.75-17.98. The analyzed texture profiles were significantly different (p<0.05). The hardness of the quail meatballs using potato flour was highest (10.08 kg), followed by the hardness of formulations using wheat (9.18 kg), corn (9.08 kg), sago (8.45) and cassava flour (7.90). The sensory evaluation of the quail meatballs generally produced a moderate score (5) on a 7-point hedonic scale. The sensory score showed that quail meat can be successfully used in the manufacture of meatballs as an alternative to other meats such as beef and chicken, using different types of flour. Cassava flour is one of the best formulations produced and is the most acceptable.
Carbon Dimer in Silicon Cage: A Class of Highly Stable Silicon Carbide Clusters
M. N. Huda,A. K. Ray
Physics , 2003, DOI: 10.1103/PhysRevA.69.011201
Abstract: A class of silicon carbide cage clusters with two carbon atoms inside the silicon cage and with high stabilities are presented. The theoretical formalism used is Hartree-Fock theory followed by second order many body perturbation theory to account for correlation effects and geometry optimizations at the second order perturbation theory level are performed without any symmetry constraints. The smallest "cage" is found to be a silicon cube with the carbon dimer inside the cube. Based on the simultaneous criteria of high binding energy, high vertical ionization potential, high homo-lumo gap, and low electron affinity, Si_14C_2 with a close fullerene like structure, is predicted to be a particularly stable cluster both al all-electron and at pseudopotential level of calculations. The C-C bond lengths and the HOMO-LUMO gaps of the clusters are both found to oscillate with the cluster size.
Novel Silicon-Carbon Fullerene-Like Cages: A Class of sp^3-sp^2 Covalent-Ionic Hybridized Nanosystems
M. N. Huda,A. K. Ray
Physics , 2003,
Abstract: A class of highly symmetric silicon carbide fullerene-like cage nanoclusters with carbon atoms inside the Si_20 cage and with high stability are presented. The Generalized Gradient Approximation of Density Functional Theory (GGA-DFT) is used to study the electronic and geometric structure properties of these structures and full geometry optimizations are performed with an all electron 6-311G** basis set. The stability of the clusters is found to depend on the geometrical arrangements of the carbon atoms inside the clusters and the partly ionic nature of the bonding. Possibilities of extending these structures into a larger class of nanostructures are discussed.
