Reproductive Activity of Mature Iraqi Bull Buffaloes: Testes Reproductive Activity of Mature Iraqi Bull Buffaloes: Testes
N.S. Ibrahim,M.M.H. Al-sahaf,A.F. Alwan
International Journal of Animal and Veterinary Advances , 2013,
Abstract: The present study was carried out to investigate the reproductive activity of mature Iraqi bull buffaloes and effect of month’s changes on the testes activity. Two hundred and fifty testes of mature buffaloes bull were taken from the slaughter house from December 2010 to September 2011. After slaughtering the length and width of the right testes were measured weight of the testes were also taken then carefully the epididymis were dissected. The diameters of testicular seminiferous tubules were also measured. The present study demonstrated a significant increased (p<0.05) in weight (g), length and width (cm) in the testes in March and April. The diameter of the seminiferous tubules demonstrated higher (p<0.05) significant in April, March and May, thickness of seminiferous tubules demonstrated higher significance in April, May and March. The increase in spermatogenesis process lead to increase the diameter and thickness of seminiferous. Conclusions reproductive activity of bull buffalo and semen physical characteristics decreased in hot months and increased in the moderate and cold months. The increase of ambient temperature in hot months lead to disturbance in reproductive activity but didn’t stop it.
Studies of The Mechanism of Polyvinyl Alcohol Adsorption on The Calcite/Water Interface in The Presence of Sodium Oleate  [PDF]
N.S. LABIDI, A. DJEBAILI
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2008, DOI: 10.4236/jmmce.2008.72012
Abstract: The adsorption behavior of polyvinyl alcohol (PVA) on the CaCO3/solution interface under the influence of sodium oleate (SOl) interaction was investigated by the adsorbed amount, FTIR spectra, X-Ray diffraction and zeta potential. Effects of solid to liquid ratio and temperature was also examined. Observed increase of the PVA adsorption in presence of the sodium oleate resulted from a polymer-surfactant complex formation. The surfactant also influences on the structure of the adsorbed polymer layers. This effect was proved by adsorption measurements that allow calculation of the thickness of the adsorbed layer of the polymer on the surface of CaCO3 in the presence and the absence of sodium oleate. The interaction between oleate anions and PVA is a physical type (via hydrogen bonding).
VEGETATION AND SOIL DIFFERENTIATION WITHIN THE LIMITS OF ECOTOPE ON THE MIDDLE URAL REGION
Ivanova N.S;
EUROPEAN JOURNAL OF NATURAL HISTORY (EJNH) , 2011,
Abstract: Transformation of vegetation and soil, which takes place in dark-coniferous forests under the action of clear fellings, fires and haymaking in dominating forest conditions of the mountains of the Middle Urals (at the bottom of draining gentle slopes), was studied. It was found that strong anthropogenic effects lead to appearance of a wide spectrum of vegetation communities within a single forest ecotope (one type of radical forests). For a long time these vegetation communities differ by the structure of all vegetation layers, conditions of soil formation, and, consequently, by the direction and intensity of restoration processes.
Effect of Planting Methods on Growth of Cassava
N.S. Oguzor
Research Journal of Biological Sciences , 2012,
Abstract: The experiment investigated the effect of planting methods on growth of cassava in Omoku climatic zone, Nigeria. Randomized complete block design was used in the experiment. The treatments were horizontal method (control), slanting method and vertical methods of planting. Comparison of treatments was done with use of percentages, mean and analysis of variance on parameters such as emergence (appearance of shoot), germinated nodes, height at 20, 40 and 60 days after planting. Analysis of the result showed that vertical method of planting cassava gave the best sprouting percentage of 88.8% while there was no significant difference on the number of germinated nodes. Based on the findings of the experiment, it is recommended that vertical method of planting cassava or slanting method should be employed because they sprouted more rapidly than horizontal method. During propagation the nodes should be placed upwards for proper and luxuriant growth of the plant.
Effect of Palm Bunch Ash on Growth of Groundnut (Arachis hypogaea)
N.S. Oguzor
Research Journal of Agronomy , 2012,
Abstract: The study investigates the effect of palm bunch ash on growth of groundnut (Arachis hypogaea). The emergence of the plant was observed to be poorly enhanced by the application of palm bunch ash. The application of 500 g and the control gave the highest emergence percentage of 25.33 and 24.7. The application of palm bunch ash affected emergence and yield significantly. It is therefore recommended that for economic purpose palm bunch ash should be applied to groundnut for optimal yield.
Agronomic Performance of Cucumber (Cucumis sativa) in a Humid Tropical Rainforest Zone of Nigeria
N.S. Oguzor
Online Journal of Earth Sciences , 2012,
Abstract: The study investigated the agronomic performance of cucumber (Cucumis sativa) in humid rainforest zone of Nigeria. The experimental design was randomized complete block design. Analysis of Variance (ANOVA) was used to analyze data collected for the study. Results revealed that the emergence of cucumber crop was relatively enhanced by the fertile status of the soil and the performance was a function of early appearance of flower which also determined the average yield. Based on the findings of the study, it is suggested that seed viability should be taken into account when cultivating cucumber. Combined application of organic and inorganic fertilizers will enhance yield.
Yield Characteristics and Growth of Cassava-Soybean Intercrop
N.S. Oguzor
Agricultural Journal , 2013,
Abstract: An experiment was conducted to investigate yield characteristics and growth of cassava-soybean intercrop. The experimental design used was randomized complete block comprising of 3 blocks and 3 replicates of sole soybean, sole cassava and cassava-soybean intercrop. Results of the experiment revealed that intercrop showed significant and positive effect on yield of soybean and cassava.
A MODULAR DESIGN OF A WALL-CLIMBING ROBOT AND ITS MECHATRONICS CONTROLLER
N.S. Tlale
South African Journal of Industrial Engineering , 2012,
Abstract: ENGLISH ABSTRACT: The modular design of a wall-climbing robot, implementing two articulated legs per module (biped robotic modules), is presented in this paper. Modular design improves a wall-climbing robot’s manoeuvrability and flexibility during surface changes or while walking on uneven surfaces. The design of the articulated legs uses four motors to control the posture of the vacuum cups, achieving the best possible contact with the surface. Each leg can contain more than five sensors for effective feedback control, and additional sensors such as gyros, CCD sensors, etc, can be fitted on a module, depending on the robot’s application. As the number of modules used in the design of the robot is increased, the number of actuators and sensors increases exponentially. A distributed mechatronics controller of such systems is presented. AFRIKAANSE OPSOMMING: Modulêre ontwerp van 'n muurklim-robot met twee geskarnierde bene per module (twee-benige robotmodules) word in hierdie artikel weergegee. Modulêre ontwerp verbeter die muurklim-robot se beweeglikheid en aanpasbaarheid tydens veranderings in die loopvlak of terwyl dit loop op ongelyke oppervlaktes. Ontwerp van geskarnierde bene implementeer vier motors wat die ori ntasie van vakuumsuigdoppe beheer om die bes moontlike kontak met die loopvlak te handhaaf. Elke been kan meer as vyf sensors hê vir doeltreffende terugvoerbeheer, en bykomende sensors soos giroskope, CCD sensors, ens. kan by 'n module gevoeg word soos die toepassing van die robot dit mag vereis. Soos die aantal modules wat in die ontwerp van die robot gebruik word, toeneem, neem die aantal aktiveerders en sensors eksponensi el toe. 'n Verdeelde megatroniese beheerder van sulke stelsels word aangebied.
