International Journal of Animal and Veterinary Advances , 2013,
Abstract: Listeria species are widely distributed in environment and L. monocytogenes are the causal agent of Listeriosis, the disease that can be serious and fatal to human and animals. The objectives of this study were to detect, isolate and identify Listeria monocytogenes from retail broiler chicken ready to eat meat products in restaurants-Khartoum state, Sudan. A total of 250 retail broiler chicken ready to eat meat products were collected from restaurants in Khartoum State, 50 sample from frozen chicken burger, 50 sample from frozen chicken sausages, 50 sample from frozen chicken meat balls (kofta), 50 sample from chicken shawerma and 50 sample from chicken mortedella, Listeria spp. were isolated by the conventional International Organization for Standardization method and L. monocytogenes identified by biochemical test. The results showed that out of total 250 samples, 95 (38%) were found to be contaminated with Listeria spp. the isolation rate was as follows: L. monocytogenes (13.6%), L. ivanovi (20.8%), L. grayi (1.6%), L. seeligeri (0.8%) and L. welshimeri (1.2%). The results presented in this study indicate the contamination of retail broiler chicken ready to eat meat products with L. monocytogenes. This study reported the occurrence and distribution of L. monocytogenes and other Listeria species in retail meat products (frozen chicken burger, frozen chicken sausages, frozen chicken meat balls (kofta), chicken shawerma and chicken mortedella), purchased from restaurants in Khartoum state Sudan.

Journal of Fisheries International , 2012,
Abstract: Gillnet selectivity and abundance of the Parailia pellucida fishery in the freshwater reaches of the lower Nun River was investigated using gillnets of 8, 12 and 15 mm classified as Small (SMS), Medium (MMS) and Large (LMS) mesh sizes, respectively. The nets exhibited selectivity with SMS catches ranging from 4.0-5.1 cm and mean of 4.70 cm Standard Length (SL), MMS between 5.0 and 6.5 cm and a mean of 5.6 cm SL, while that of the LMS gill net ranged from 6.0-10.5 cm with a mean of 7.3 cm SL. Apart from size selectivity, there was a significant difference in abundance and biomass of P. pellucida with mesh size of gill net used (p<0.05, t = 1.969, df = 2, N = 144) such that the LMS consisted of the highest abundance of 6,762 (74.4%) and biomass of 29.485 g (84.0%), the MMS 2.381 specimen (25.2%) and biomass of 5.238 g (14.8%), while the SMS constituted the least abundance of 269 (2.8%) and biomass of 409 g (1.9%). The mean monthly abundance and biomass were: SMS -11.21 (17.09 g), MMS -85.58 (217.21 g) and LMS -281.75 (1.230 g).

Asian Journal of Agricultural Sciences , 2010,
Abstract: Macrobrachium macrobrachion morphology and abundance in Luubara creek, of Ogoni Land, in the Niger Delta region of N igeria was studied for a period of tw o years (January, 2006 to December, 2007). It was not different from other Macrobrachium species. The body is divided into three main divisions: the head, thorax and abdomen. The head and thorax are joined to form a cephalothorax, containing the mandibles, flagella, rostrum and the eyes containing a stalk containing five pairs of walking legs. The abdomen contains six body segments with last segment bearing a uropod (telson). The other five segments bear swimming apparatus (swimmerets). The second walking legs are modified to form the chelae and distinctively colored either blue or brownish colors. The legs contain hairs (furs). Mature males are considerably larger than females. The second walking leg of the male is thicker. Cephalothorax is also proportionally larger in the male than female while abdomen is narrower in the female. Genital pores of the male are between the bases of the fifth walking leg. The female genital pores are at the base of the third walking legs. Abdomen pleura are lower and the abdomen broader in female than male. Female pleura form a brood chamber that caries eggs between laying and hatching. A ripe ovigerous female can easily be identified with large orange-colored mass ovaries occupying a large portion of the cephalothorax. Station 1 had total 385 shrimps in 2006 and in 2007 the total number of shrimps was 246. The highest number of female shrimps was recorded in March 2006 while no shrimps were observed in September 2006. The least number of females was recorded in October 2006 and in September and October 2007. The least number of males was recorded in June 2006 and in September, 2007; while the highest number of males was in February, 2006 and January 2007. In terms of sex ratio, the females were more than males (1:1.6). The total number of shrimps obtained in station 2 was 1,006 out which 378 or 35.57% were males while 628 or 62.42% were females. In station 2, the highest number of shrimps was recorded in January 2006 while the lowest was in September 2006. Also in 2006, highest number of males was recorded in January while the least number of males was in September. In 2007, the highest number of males was recorded in January, 2007 and the least in October. The highest number of females was recorded in March, 2006 while the month of December, 2006 recorded the least number of females. In 2007, the highest number of females was in October, while the lowest number of fe

Abstract: Pulverised stem fibres of the natural sponge plant, SP, (Acanthus montanus) and stranded coconut fibre, CF, (Cocos nucifera) from the coir tree were used as reinforcements for thin cement sheets in this research work. The mixture of cement and pulverised waste paper, which formed the matrix, was maintained constant while the fibre mass concentration of both fibres were varied. The slurry formed by adding water to the mixture of the matrix materials and the reinforcement fibres, was poured into rectangular mould and consequently pressed to eject excess water. De-moulded samples were allowed to cure in the laboratory for twenty-eight days before flexural and compressive tests were carried out. The analysis of the experimental results established that sample coded as S4, with 30% CF and 70% SP, showed the most promising result. This implied that particulate reinforcement in cement matrix composite contributed to higher and improved flexural load bearing capacity and ductility when utilised in a higher proportion than long fibres.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.88051
Abstract: Natural sponge fibre (Acanthus montanus) was used as reinforcement for ceiling materials in this research work. This fibre, being fairly strong and stiff as well as cheap and plentiful with low energy demand during manufacture, are strong contenders for the reinforcement of cementbased materials. The fibre, whose mass fraction was the variable in this work, was cut down into smaller sizes and mixed with pulverised waste paper, cement and water. The resulting slurry was then poured into rectangular moulds which were compacted until the excess water was expelled and resulting composites became hard. Demoulded samples were left to cure in the open laboratory air for 28 days. Flexural and water absorptivity tests were carried out on the various samples which showed that reinforcement and best mechanical properties were obtained at optimum fibre mass fraction of 4% when compared with the brittle matrix in the absence of reinforcement. These tests confirmed the possible use of sponge fibres as reinforcement in cement matrices for ceiling purposes.

Abstract: Fifty ear swab samples were examined from pediatric patients attending Aminu Kano Teaching Hospital, Kano. The samples were collected from ENT department, pediatric out patients department (PODP) and General out Patients Department (GOPD). The swabs were tested by culturing for bacterial pathogens, where 47 (94.0%) of the samples yielded growth. The most predominant isolate was Staphylococcus aureus, with a total occurrence of 26 (55.32%) followed by Proteus mirabilis, Pseudomonas aeruginosa, Klebsiella pneumoniae and Streptococcus pneumoniae, with total occurrences of 12 (25.53%), 7 (14.89%), 1(2/13%) and 1 (2.13%) respectively. Based on age group, 0-2yrs age group were more infected (16 infected). Of the two sexes, males were 28 (56%) while females were 22 (44%) and all were within the age range of 0- 12 years. Antimicrobial sensitivity test showed that the bacterial isolates were susceptible to Augmentin, Gentamycin, Tetracycline, Amoxicillin and ofloxacin but resistant to Ampicillin, Streptomycin, Cotrimoxazole, cefixime and Cloxacillin.

Journal of Animal and Veterinary Advances , 2012,
Abstract: The objective of the present study was to investigate the effect of raw and differently processed (cooked, dehulled and toasted) kidney bean meal on the performance of broiler chicken. Histological examinations of internal organs were also conducted in a feeding trial that lasted for 56 days. Two hundred and twenty five day old broiler chicks (Anak strain) were used for the study. There were five treatment groups of three replicates of 15 birds per treatment. Raw and processed kidney bean meal was used to replace 50% protein supplied by soybean in the control diet. Data collected was used to evaluate feed intake, weight gain and efficiency of feed utilization. The weights of liver, pancreas, kidney, heart and lungs were also recorded and tissue samples of each collected for histological examination. Food intake was unaffected by the dietary treatments. Significant (p<0.05) differences were obtained in Average Daily Gain (ADG) and efficiency of feed utilization (FCE). ADG in birds fed cooked kidney bean was significantly (p<0.05) higher than those fed toasted. ADG was depressed in birds fed raw and dehulled meals. Feed Conversion Efficiency (FCE) followed the same trend as ADG. The relative weight of the pancreas was significantly (p<0.05) increased, as a result of acinar hypertrophy. The kidney had severe congestion of glomeruli and distention of the capillary vessels with numerous thrombi in birds fed soaked and decorticated kidney bean meals. The weight of the liver was significantly (p<0.05) reduced in birds fed soaked and decorticated beans and it was characterized by marked coagulative necrosis and degeneration of the hepatocytes. The structural alterations were attributed to high concentration of residual anti-nutritional factors in the processed seeds. In conclusion, cooked kidney bean meal can be used to replace 50% protein supplied by soybean meal in broiler starter and finisher diets without any adverse effect on the performance and the intestinal organs.

Abstract: In recent decades the number of gray ducks within range of the species has declined sharply, it has been includedin several national Red books, including the Ukrainian one. Restoration of this species is only possible by studying ofthe features of its biology and amendments to the game hunting. The lake forest-steppe part of Western Siberia is stillthe center of the reproduction of gray duck. Reproductive capacity of this species is extremely high. The brood had upto 6-13 eggs, with an average of 8. Early clutches contain on average 9-11, late - 6 eggs. In broods there are 6-11, withan average of 8 chicks. Mixed stack with other species of ducks make up to 2,7%. The breed mortality in different yearswas up to 66,7%, the eggs - up to 20,5%, mortality of nestlings - 30,9%. To restore the population of gray duck huntingreserves it is recommended to conduct the biotechnology activities, to create special conditions for transition to colonialtype of breeding.

Proceedings of the International Conference Nanomaterials : Applications and Properties , 2012,
Abstract: We have elaborated methods for synthesis of macromolecular metal complexes via homo- and copolymerization of metal-containing monomers (unsaturated metal carboxylates, metal nitrates acrylamide complexes. Thermal transformations of such compounds possess the unique way for preparation of nanocomposite materials when metal (or their oxides and carbides) nanoparticles and a stabilizing polymer matrix are formed simultaneously in situ. Molecular and supramolecular organization of nanocomposites obtained can be controlled during the thermal transformation of such monomers in inert or self-generated atmosphere. The process includes three macrostages: dehydration, solid-phase polymerization, and pyrolysis of the polymer products formed. The approach makes it possible to adjust the mean particle size in a given range by just choosing the appropriate reaction conditions. The composition of metal nanoparticles, their size and distribution on the size as well as the type and thickness of polymer shell can be controlled on the stage of nanocomposite formation. The nanocomposites obtained reveal ferromagnetic behaviour at room temperature with high coercive force and magnetic anisotropy. With aim to control the composition and structure (for example, core-shell type) of ferromagnetic nanomaterials obtained as well as their properties, the reaction conditions such as temperature, ratio of starting compounds, the type of polymer matrix can be varied. Keywords: Nanocomposites, Thermolysis, Solid-phase polymerization, Metal nanoparticles, Core-shell structure.
