Correlation Between Body Weight and Body Conformation of two Broiler Strains Under the Same Dietery Treatment
H.K. Yahaya,H. Ibrahim,S. Abdulsalam
International Journal of Animal and Veterinary Advances , 2012,
Abstract: The objective of this study is to estimate the correlation between body weight and body conformation of two broiler strains. A total of 200 broiler chickens comprising of 100 Hubbard and 100 Arboracre strains were used in the determination of their correlation between body weight and body conformation from day old to 8 weeks (0-8 weeks) of age. Weekly body weight and body conformations like shank length, keel length, breast width, back length and neck length were taken thrice in a week and the correlation between body weight and the body conformations were computed at the 8th week of the experiment for both strains. Hubbard broiler strain had the correlation of 0. 9416, 0.894, 0.861, 0.897 and 0.963 between body weight and other body conformation while for Arboracre strain, the correlation of 0.967, 0.974, 0.882, 2.935,0.981 and 0.969 were obtained between body weight and back length, shank length, thigh length, keel length, breast width and back length respectively. The correlation between other body conformations range between 0.977 and 0.795, all indicating strong positive correlations. Hence, there is a strong linear relationship between body weight, neck length, shank length, thigh length, keel length, breast width and back length for both Hubbard and Arboracre strains.

H.K. Yahaya,H. Brahim,S. Abdul Salam
International Journal of Animal and Veterinary Advances , 2012,
Abstract: This study is aimed at comparing the two important economic traits (body weight and conformations) of Hubbard and Arboracre commercial broiler chickens treated under the same dietary and environmental conditions. A total of two hundred broiler strains comprising of 100 Hubbard and 100 Arboracre strain were used in the comparative evaluation of their body weight and body conformation from day old to 8 weeks of age. Body weight were taken on weekly basis while linear body measurement like shank length, breast width, back length, neck, thigh length and keel length were taken three times a week. Hubbard broiler strain had the body weight of 0.298±0.0287, 1.0083±0.0123, 2.063±0.0219 and 3.079±0.02J kg while Arboracre strain attain the body weight of 0.2603±0.0587, 0.8125±0.0185, 1.7100±0.0287 and 2.604±0.0219 kg, respectively all at 2.46 and 8 weeks of age. The linear body measurements of Hubbard strain were significantly higher than that of Arborace strain (p<0.05) at 8 weeks of age for all parameters studied. Hubbard broiler strain showed superiority in growth assessment of body weight and linear body measurements in the 0-56 days stuffy period.

G.N. Akpa,H.K. Yahaya,U.C. Martin
International Journal of Animal and Veterinary Advances , 2012,
Abstract: The aim of this research is to analyse the semen of different breeds of rabbits and to determine the effects of age, breed, sire, generation and body weight on the ejaculate characteristics of rabbit bucks. Twenty rabbit bucks comprising of three breeds (New-Zealand White 8, Chinchilla 6 and Californian White 6) between the ages of 6-9 months were used to investigate the effect of age, breed, sire and generation on body weight and ejaculate characteristics of the bucks. The experiment was carried out at the Animal Science departmental farm, Ahmadu Bello University, Zaria. Parameters considered include semen colour, semen volume, semen ejaculate volume, semen concentration, semen pH, sperm motility, body weight and age. The mean for semen ejaculate volume, semen concentration, pH, sperm motility, body weight and age were 0.5 mL, 325.5x106 sperm cells/mL, 7.5, 86.6, 2.0 and 7.6% months, respectively. Age, breed and sire had (p≤0.05) effect on ejaculate characteristics but breed and sire had higher significant (p<0.01) effect on body weight. However, generation had no significant effect on the body weight and ejaculate characteristics except on semen pH (p<0.05). The ejaculate characteristics of the rabbit bucks were influenced by age, breed and sire. The values obtained were within the normal standards for rabbits-bucks. New Zealand White bucks proved superior in terms of ejaculate characteristics.

S.S. Mohammed,A.A. Orukotan,H.K. Yahaya
British Journal of Pharmacology and Toxicology , 2012,
Abstract: An estimation of Nickel bioavailability in guinea corn and soils from Kaduna metropolis was carried out. The objective of the study was to determine the bioavailable Nickel in guinea corn and soil samples by Flame Atomic Absorption Spectrometry (FAAS) using sequential extraction technique. The results indicated that the soil samples collected from various locations contain varying amounts of Nickel and were distributed between residual, oxide and carbonate/organically bound phases. The results also indicated that in all the sampling sites, Nickel concentration is below the tolerance limit value of 50 mg/kg and the ANOVA (p = 0.070>0.05) indicated no significant difference in the Nickel concentration across the various guinea corn crops. Similarly the ANOVA (p = 0.004<0.05) showed a significant difference in the Nickel concentration across the various guinea corn soils.
Theft and robbery in chrysostom’s time
H.K Stander
Acta Theologica , 2009,
Abstract: The aim of this article is to study what Chrysostom said about theft and robbery in his community. His homilies on the New Testament will be scrutinized for information on this negative feature of the ancient world, since homilies are always important sources for information on social issues. It becomes clear that house-breaking was quite common, and that robberies were often associated with violence. Even tombs were robbed and were plundered of valuables. Robbers were severely punished and for a single theft one could spend the rest of one’s life in prison. Prisoners were also dependent on their family or on the charity of Christians for food. But Chrysostom also looked at robbery from a theological point of view. He ascribed it to the working of demons. When we are robbed, we are confronted with various choices: we can curse the robber, or we can plot against him, or we can thank God. This study will make a contribution to our knowledge of the social history of the ancient world.

A preliminary study on estimating extra-cellular nitrate reductase activities in estuarine systems
H.K. Pant
Knowledge and Management of Aquatic Ecosystems , 2009,
Abstract: Enzymes catalyzing ammonium (NH4+)/nitrate (NO3–) into nitrous oxide (N2O)/molecular nitrogen (N2), play critical roles in water quality management. The objective of this paper was to investigate the role of extra-cellular enzymes in cycling of nitrogen (N) in aquatic systems. It appears that N in estuaries, salt marshes, etc., does not stay long enough to be available for uptake, thus, creating N limited conditions. This study showed that indigenous extra-cellular nitrate reductase along with others involved in N transformations in the waters/sediments of estuarine systems can cause complete removal of NH4+ and NO3– from the waters and available NH4+ and NO3– from the sediments. These results indicate that due to high extra-cellular nitrate reductase and other enzymes associated with N transformations in sediments/waters, substantial amounts of NH4+ and NO3– can be quickly lost from the systems as N2O and/or nitric oxide (NO), in turn, creating N limited conditions in estuarine systems. Such high activities of indigenous nitrate reductase and others are useful in removing readily bioavailable N from the systems, thereby avoidance of eutrophic conditions. However, they might contribute in increasing the N2O, a potent greenhouse gas with global warming potential (GWP) of 296, in the atmosphere.

H.K. Huang
Iranian Journal of Radiology , 2007,
Abstract: We give a historical review of PACS development during the past 25 years. The first 10 years was mainly in laboratory research and development. The second 10 years was in clinical usage and workflow analysis. During the past five years, research and development have been in developing the concept of imaging informatics, and CAD and PACS integration. The future trend will be in using images to bridge the gap between diagnosis and therapies including surgery, radiation treatment, and image-guided target drug delivery.
Invited Speech: HIS/RIS/PACS/ePR
H.K. Huang
Iranian Journal of Radiology , 2007,
Abstract: This presentation will discuss four topics: "n HIS/RIS/PACS integration"n Medical image and data Standards"n IHE (Integrating the Healthcare Enterprise) Pro-files"n ePR (electronic Patient Record)"nPACS is an imaging management system that requires pertinent data from other medical information systems for an effective operation. Among these systems are hospital information system (HIS), and radiology information system (RIS). A voice recognition (VR) system can also be used to generate a radiology report as a direct output of the RIS which can be considered as a component of RIS. Many functions, for examples, image routing, prefetching, automatic grouping, etc. in the PACS server and display workstations rely on data extracted from both HIS and RIS. This presentation first discusses the infrastructure and functions of HIS, RIS, VR and data which are important to PACS operation, and their interfaces. HIS and RIS follow HL-7 (Health Level 7) data format and TCP/IP communication standards, PACS uses DICOM (Digital Imaging and Communication in Medicine) image format and communication standard. The success of PCAS, HIS, and RIS interface rely on the conformance to these standards of each information system during system operation. "nTo interface HIS and RIS with PACS, certain guidelines are necessary including:"n(1) Each system (HIS, RIS, PACS) remains unchanged in its configuration, data, and functions performed."n(2) Each system's hardware and software are ex-tended to allow for communication among systems."n(3) Only data are shared; original system functions remain local. For example, RIS functions should not be performed at PACS or HIS workstation, or images should not be viewed at RIS workstation. Keeping each system specific and autonomous would simplify the interface process, since a complete database updates is difficult to perform at a global level."nBased on these guidelines, successfully interfacing HIS, RIS, and PACS should follow these steps:"n(1) Identify the subset data that would be shared by other systems. Set up access rights and authorization for each system."n(2) Convert non standard subset textual data to HL 7. This step, composing of designing a high level presentation, solving data inconsistencies, and naming conventions, can be accomplished by using a common data model and data language for all systems, and by defining rules of correspondence between various data definitions among systems."n(3) Define communication protocol of data transfer, i.e., TCP/IP or DICOM."nIn general, medical imaging industry conforms to the aforementioned
Invited Speech: PACS Planning and Implementation
H.K. Huang
Iranian Journal of Radiology , 2007,
Abstract: This presentation will be in two parts: PACS implementation strategy and clinical implementation. A PACS consists of many imaging modalities and ICT (information and communication technology) components to form an integrated system for clinical practice in radiology departments, medical centers, and healthcare enterprises. During the past 25 years, many hospitals and manufacturers in the United States and abroad have researched and developed PACS implementation strategy of varying complexity loosely categorized into five models according to methods of implementation in clinical environment. The advantages and disadvantages of these models will be discussed in details first, in-cluding."n1- The home-grown model "n2- Two-team effort model"n3- Turnkey Model"n4- Partnership Model"n5- Application Service Provider (ASP) Model."nThe second topic will be in PACS clinical implementation, acceptance, data migration and system evaluation. Panning to install a PCAS needs to consider:"n1- Cost analysis"n2- Current film-based operation"n3- From film-based to uture digital-based operation"n4- Template for PACS RFP (Request for Proposal)"n5- Preparing for PACS implementation"n6- Check list during implementation"n7- System acceptance"n8- PACS system evaluation
