ABSTRACT:Field trials were conducted in 2016 at Ahmadu Bello University, Zaria in Northern Guinea Savanna and Kadawa, in Sudan Savanna of Nigeria, to study yield and yield components of rice varieties as influenced by NPK fertilizer and stand densities. The treatments consisted of two lowland rice varieties (FARO 44 and FARO 52), three NPK fertilizer (40:20:20, 80:40:40, 120:60:60) kgha-1 and three level of plants/stand (2, 4 and 6). The treatments were factorially combined and laid out in a randomized complete block design and replicated three times. The result showed that yield parameters were enhanced with increased rate of NPK fertilizer with optimum grain yield obtained from the application of NPK 120:60:60 kgha-1 . Also 2 plants/stand densities gave the highest grain yield components which translated into higher grain yield. Among the two varieties evaluated, FARO 52 gave higher value for most yield components, however, FARO 44 gave higher harvest index and grain yield. The interaction between 2 plants/stand densities with the application of NPK 120:60:60 kgha-1 resulted in maximum yield of 6479.3 kgha-1 at Kadawa and 5762.5 kgha-1 at Samaru. The interaction between FARO 44 with the application of NPK 120:60:60 kgha-1 gave maximum yield of 5882 kgha-1 . It can be concluded that, sowing FARO 44 at 2 plants/stand with the application of NPK fertilizer at 120:60:60 kgha-1 gave optimum grain yield per ha.

ABSTRACT:The determination of the potential evapotranspiration using the Penman-Monteith model for Owerri has been carried out. Potential evapotranspiration represents the environmental demand for evapotranspiration for a location which reflects the energy available to evaporate water from the ground into the lower atmosphere.The data for this work were collected from the Nigeria Meteorological Agency, Owerri which is at altitude 160 m, latitude 50º 00′ N and longitude 06º 05′ E. The result of this work shows that the maximum potential evapotranspirationoccurs from January to March, then drops considerably from April to September and then rises from October to December. This result is useful to farmers and horticulturalists in determining when to farm and to irrigate the farms and gardens.

ABSTRACT: This study was to determine the prevalence of WMSDs among commercial tricycle in Borno State. Across-sectional study of the commercial tricycle riders was carried out using the standardized Nordic Questionnaire. Descriptive Statistics of mean, standard deviation, frequency and percentage were used to summarize the data, while chi-square was used to test difference in prevalence of WMSDs of selected socio-demographic and work-related characteristics of the participants at 0.05alpha level. Work related musculoskeletal disorders (WMSDs) have become a major problem in many industrialized countries and a comparable trend has also been observed in developing countries. The results showed the overall 12 months prevalence of self –reported WMSDs to be 99.7%., with the two shoulders most commonly affected with a prevalence of 89.1%. There was statistically significant difference in 12 months prevalence of WMSDs among commercial tricycle riders of different educational level (x2 =11.449; P-value=0.010) with those in the age group of 18-35 years recorded the highest prevalence rate of 78.2%. There was a high 12 months prevalence of WMSDs among the commercial tricycle riders with the highest prevalence observed in the shoulder region. This study supports the need for vigilant ergonomic intervention at job sites and early ergonomic education as an integral part of apprenticeship and training of commercial tricycle riders in order to prevent the incidence and prevalence of WMSDs among this group of individuals.

ABSTRACT: Murraya Koenigii is a medicinal plant, which is claimed to have hypoglycemic potentials. The study was carried out to investigate the toxicity of long time usage of Murraya Koenigii in normal and alloxan-induced rats. In this study 30 rats were used which includes 5 normal rats, 5 diabetic untreated rats, 5 diabetic treated with aqueous extracts, 5 diabetic rats treated with ethanolic extract and 5 diabetic rats treated with standard drug. Aqueous and ethanolic extracts of this plant were prepared and blood glucose lowering effect and improvement of body weight gain in alloxan induced diabetic rats were measured and compared with that of standard drug. Rats were administered Murraya Koenigii extracts orally for 28 days, respectively. The animal were further sacrificed after the study and their serum collected to test for the effect of the extract on the liver and kidney. Although aqueous extract was more effective and no significant effect on the liver and kidney parameters when compared with non-induced untreated group. The data were compared statistically by using student’s unpaired t-test. The present study clearly indicated that the ethanolic and aqueous extract of Murraya Koenigii has some hypoglycemic properties and maybe safe to use.

ABSTRACT: Bacteria among other microorganisms viz fungi, viruses, protozoans and even some metazoans are ubiquitous and as well survive in different environments. Despite the fact that some microorganisms are beneficial while others are not, yet the diversity in habitat occupied by bacteria makes it easier for them to cause infections especially whenever the environments is conducive as in the case of opportunistic infections. The study was undertaken to identify the bacteria associated with hand palms and armpits of healthy subjects and also to evaluate the antibiotics sensitivity patterns of the bacteria. The study population consisted of seven males and four females healthy students of Adekunle Ajasin University Akungba-Akoko, Ondo State Nigeria between the age of eighteen (18) and thirty (30) years old. All the bacteria encountered were cultured on tryptone soya agar and eosin methylene blue agar, while only Gram-positive cocci were cultured on mannitol salt agar. The bacterial isolates were identified based on cultural, morphological and biochemical characteristics. Out of the sixteen bacteria obtained, 4(25%) were Staphylococcus aureus, while Streptococcus species and Staphylococcus species were 3(18.75%) each. Other bacteria identified were 2(12.5%) of each Corynebacterium species and Klebsiella species. In addition, Clostridium species and Bacillus species constituted 1(6.25%) each. Antibiotics susceptibility patterns of the bacteria were determined by disc diffusion method. All the bacterial isolates tested showed multiple antibiotics resistance.

ABSTRACT: The pictorial imagery on ceramic wares and other surfaces is an enhancement to the wares as well as the paintings on the walls or canvas and other surfaces. The two areas in focus are associated with colours for aesthetic function. Colours in ceramics are uniquely achieved from various glaze compositions and varying approaches in heating ceramic wares. The colour changing attitude of chameleon is occasionally noticed in ceramic colour (glaze) firing exploration. Oxidation firing is exposed to changes in colour from the intended colour when the firing technique changes to reduction firing, as well as influence from other factors. Painting technology engages in applying colours to various surfaces such as wood, metal, canvas, cement walls and other surfaces for aesthetic function or beautification. Ceramics is a three dimensional art while painting is a two dimensional art, but they interrelate in various ways such as the issue of colour expression on the surfaces to enhance beauty of the products. Pablo Picasso and Michelangelo were great and successful Painters who were renowned in colour application on surfaces to promote aesthetic function. Equally, inner and outer surfaces of some ceramic wares require colour by such form surfaces to boost aesthetic value, even though the wares have utilitarian function also. In this study the five visual images of ceramics and five painting works were perceived and described, interpreted and assessed. Each has the capacity to fulfill either utilitarian or aesthetic functions or both of them. The paper addressed the interrelationship of ceramics and painting technology and a simple survey research designs was adopted, where data were analyzed and summarized considering predetermined themes. Ceramics and painting technology are interrelation and also play immense role in the development of mankind and the society

ABSTRACT: A study was carried out to investigate the physico-chemical characteristics of oil obtained from two freshwater cichlids. The experimental fish species studied were Oreochromis niloticus and Sarotherodon galilaeus. Extracted fish oil was evaluated for saponification, acid, iodine and peroxide values following standard procedures of the Association of Analytical Chemists. Sarotherodon galilaeus had significantly (p<0.05) higher saponification value of 26.37 mg KOH/g compared to Oreochromis niloticus (9.82 mg KOH/g) implying smaller molecular weight of the fatty acids of glycerides in the former. Oreochromis niloticus and Sarotherodon galilaeus oil are characterised by low iodine and peroxide values which connotes great oxidative storage stability and non-susceptibility to rancidity. Thus the selected cichlids’ oil are of high quality and safe for human consumption (peroxide value <5.0 meq/Kg).

ABSTRACT: It can be affirmed that the salary is the income of the employee based on the quantity and quality of labor while performing the work of the employee according to the commitment between the employer and the employee. For businesses, salary is an extremely necessary and important expense. Therefore, the accounting of wages for enterprises must be done correctly and reasonably. This is because, the salary paid in accordance with the labor results will stimulate the employees to work, effectively work for the business, promote the spirit of work hard, creative in the process of labor. . In addition to the main salary, the employee is entitled to the bonuses, allowances, health insurance, social insurance, unemployment insurance, which are social funds that employees enjoy, it represents the concern of society, of business to each member of the enterprise. For manufacturing and trading enterprises, wages are a big part of production costs. Therefore, if enterprises know how to apply a reasonable salary regime, they will create motivation to increase labor productivity, stimulate production to develop and bring profits to businesses. The construction of a salary management information system aims to provide managers with general information on the implementation of salary payment for employees, seeing the main advantages and disadvantages in management as well as going into the policy of reasonable and most favorable salary and wage norms for employees at enterprises. Since then, help businesses do well the management, bring high efficiency for businesses.

ABSTRACT: The ambition of writing on Singer notion of animals’ rights is to possibly bring to our attention that we should change from the way we look at nonhuman animals. Singer understands nonhuman animals as having rights because they can experience pain. We may logically argue that, he understands rights, as that which protects animals from exploitation. Though he is out to defend nonhuman animals, he seems to end up not bridging the conviction that man is a central part in the universe hence deserves treatment of other animals as mechanism for his survival. When he argues that, man has the right to do away with nonhumans especially those which threaten him. The act of giving room for brining nonhuman animals to impulsive death is an act of domination over them and a violation of sentience which he basis animals rights on. The researcher shall employ analytic method as a means of addressing the Singer’s notion of animals’ rights which shall probably make it possible to show his ambivalent on this issue of nonhuman animals’ rights. Once we understand rights in holistic manner, we may have reached the culmination of human understanding of nonhuman as having rights

ABSTRACT: The discharge of waste engine oil (WEO) into gutters, water drains, open vacant plots and farms is a common practice in Nigeria especially by motor mechanics. Much of this oil is poured into the soil and its presence is usually harmful to soil living forms. This study examined the ecotoxicological effects of discharging waste engine oil (WEO) on soil biological sentinels. The soil samples were obtained from three (3) different sites (0-1 5cm2 depth) and merged together to form a composite soil. Nitrobacter spp. was isolated using heterotrophic nitrobacter medium. Acute and chronic, toxicity tests for Nitrobacter spp. and Apporectoda alonga (earthworms) were carried out. The physicochemical parameters of the composite soil contaminated with different concentrations of WEO were also determined. Analyses of the samples indicated that the various concentrations of WEO (50%, 100% and 200%) in liquid medium containing Nitrobacter spp. were increasingly acidic with a corresponding pH of 5.1 2, 4.80 and 4.56. Dissolved Oxygen (DO) was drastically reduced from 9.20 in the control sample to 4.85 at 200% concentration. With increasing concentrations of WEO, there was a gradual decline in total Nitrobacter count in the soil from 1.7 x 101 cfu/g in the control sample to 0.5x101 cfu/g at 200% concentration. The percentage inhibition on Nitrobacter increased hourly as WEO concentrations increased from 3% inhibition (1st hr) to 13% inhibition (3rd hr), signifying the lethality of WEO on soil microbial activities. Nitrite concentration in the soil decreased across the various times analyzed. Chromium, Cadmium. Nickel, Copper and Iron values decreased weekly across all concentrations (50%, 100% and 200%). In the 28 days span, growth rate of earthworms (A. longa) in the soil was drastically reduced as concentrations of WEO increased. At 50% concentration of WEO, 0% death rate was recorded in the first week. However, by the 3rd and 4th weeks, a maximum of 100% death rate respectively was recorded at the highest concentration of WEO; thus highlighting the contributions of WEO to the toxicity and death of free living organisms in the soil.

ABSTRACT: Intraosseous (io) access is an alternative way of administering fluid and drug and also taking biopsies needed for clinical and laboratory tests in cases when peripheral venous access couldn’t be established. The io route was successfully secured in all cases with a significant shorter time of vascular access insertion, shorter length of stay and reduction in mortality in io group vs. Iv group. Io access was first used in 1922. This technique was widely used during 1940’s when emergency medical care was routinely needed for seriously injured patients in world war ii. Since 1950’s after the introduction of peripheral venous access technique io access lost its actuality. In management of pediatric emergencies intravascular (venous) access is prior but sometimes establishing peripheral venous access is impossible or it may take too much time because of anatomical or physiological characteristics, such as an excessive subcutaneous fatty tissue and veins with a small diameter. Vasoconstriction, reduction of circulating blood volume and peripheral venous collapse takes place during cardiopulmonary arrest, septic or hypovolemic shock and prolonged status epilepticus. This features alone or in combination can make venous catheterization impossible. For pediatric resuscitation, vascular access must be established quickly, often in difficult circumstances. Alternative methods of peripheral access, such as umbilical catheter, central venous lines, venous cut-down, and ultrasound guided access, may be poor options because of the patient’s age or condition, the urgency of resuscitation, and/or the skill of available clinicians. Anatomically, the described site is suggested to offer a safe alternative access point for emergency infusion in severely hypovolemic newborns and infants, without the risk of damage to any anatomical structures. Io access complications are infection - cellulites, abscess, osteomyelitis and fracture. The most widespread complication is extravasation, which, if left unidentified, can cause compartment syndrome. The ez-io® device is easy to use and requires minimal training. These studies suggest that the ez-io® is an easy to use, easy to learn tool that can be used successfully in resuscitation scenarios with minimal training. It is evident that blood samples drawn immediately after intraosseous cannulation can provide accurate laboratory and blood bank data to aid in resuscitation. More recently, the pharmacokinetics of intraosseous drug delivery has been compared with central venous drug delivery.
