The Behavioural Pattern of Pregnant Mothers towards Antenatal Clinics and Its Implications on their Nutritional Knowledge in Obio-Akpor Local Government Area, Rivers State

Abstract: The study examined the behavioural pattern of pregnant mothers towards antenatal clinics and its implications on their nutritional knowledge. The study adopted descriptive cross sectional study with a target population of pregnant women in the some selected villages in Obio/Akpor Local Government Area. The sample size of the study comprised 200 pregnant women attending their normal antenatal cares clinics in the sixty-six (66) primary health care centres in Obio-Akpor Local Government Area. The instrument for data collection was questionnaire. To ensure the validity of the instrument, the questionnaire was being giving to the women during their antenatal visit in the hospitals and lectures in the department of Food Sciences and Technology for scrutiny and suggestions, correction and amendment. The data obtained from the sampled respondents through the use of structured questionnaire were analyzed using frequency, percentage, cumulative percentage, mean and standard deviation. The result of the findings indicated that majority of the respondents strongly agreed that the most observable negative implications of pregnant mothers’ behavioural pattern towards antenatal cares clinic on their nutritional knowledge is that it increases the potential health risks during and after pregnancy while lesser number of the respondents strongly believed that the negative implications could be a reduction in the intake of nutrient capable of preventing anemia in the mother and lacks knowledge on the relevance of balanced diets during pregnancy. Therefore, it was recommended that the relationship existing between pregnant mothers and personnel of antenatal clinics should be made more cordial through increased awareness especially to pregnant mothers on the roles of antenatal cares clinics in ensuring the development of fetus and ensuring good maternal health. This will reduce the nonchalant attitude existed by pregnant mothers in seeking available antenatal care.

Determination of Increase in Yield of Tropical Grasses Inoculated with Spirillum lipoferum

Abstract: Increase in yield of tropical grasses viz. digit grass (Digitaria decumbens), guinea grass (Panicum maximum) and pearl millet (Penisetum americanum) inoculated with tropical nitrogen-fixing bacterium, Spirillum lipoferum was investigated. The study was carried out for three consecutive years (2016-2018). Dry matter yields and protein content of the three tropical grasses were used for the assessment. In 2017, pearl millet (Penisetum americanum) and guinea grass (Panicum maximum) produced significantly higher protein content and dry matter yields. Projected yields using regression analysis of both pearl millet and guinea grass indicated that about 40kgN ha yr were replaced by inoculation. Although, protein production of guinea grass was lower during 2018, dry matter yield responses were similar to those of 2017. This research has shown that inoculation with Spirillum lipoferum, a tropical nitrogen-fixing bacterium reduced acetylene and increased yields or reduced nitrogen fertilizer requirement of the tropical grasses as well as replacement of up to 40KgN ha. This amount is agro-economically important and suggests the viability and potential for grassbacteria systems.

Review of Mathematical Modelling of the Time Dependent Schrodinger Wave Equation using Different methods

Abstract: This paper focuses on the principle of time dependent Schrodinger equation (TDSE) which simplified so many reviewed ideas, class room teaching, research ideologies and personal study meant for advanced knowledge. In this research work, the enlightenment of the basic concept of Schrodinger wave equation to improve knowledge about simple ways for mathematical understanding in deriving TDSE using different technique in more comprehensive approach. The research shows clearly that TDSE can be derived using time independent equation, wave mechanics, classical & Hamilton-Jacobi’s equations. Different methods and ways by different researchers/scholars have been used in the past. In this paper, we review the quantum field theoretic route to the Schrodinger wave equation which treats time and space as parameters, not operators. Furthermore, we recall that a classical (nonlinear) wave equation can be derived from the classical action via Hamiltonian-Jacobi theory. By requiring the wave equation to be linear we again arrive at the Schrodinger equation, without postulating operator relations. The underlying philosophy is operational. Surely, a particle is what a particle detector detects. This leads us to a useful physical picture combining the wave (field) and particle paradigms which points the way to the time-dependent Schrodinger equation. However, the result provides a comprehensive well derived derivation, derived using various approaches, which would make this research a unique one from different areas of specializations.

The Nigerian local chicken hormonal functional status as influenced by age and sex factors

Abstract: A study was conducted to investigate the effect of age and sex on the hormonal status of the Nigerian Local Chicken raised in the Teaching and Research Farm of the Rivers State University Nkpolu-Oroworukwo, Port Harcourt. A total of forty (40) heterogeneous population of the Nigerian Local Chickens were used in a Completely Randomized Block Design (CRBD). Blood samples were collected from 10 males and 10 females from two different age groups (21 and 72 weeks). Hormonal assay was conducted to ascertain the values of some growth and reproductive hormones. These includes; thyroxin (T4), Triiodothyroxine (T3), Thyroid stimulating hormone (TSH). Prolactin (PRL), testosterone (TET), estrogen (E), luteinizing hormone (LH), follicle stimulating hormone (FSH) and progesterone (PROG). PRL, FSH, PROG and TET were significantly (p<0.05) affected by age while others were not significant (p<0.05). Prolactin had higher value for birds under the ages of 21 weeks than 72 weeks of age with a corresponding value of 28.35ng/mL and 8.64ng/mL respectively. Sex effect on hormones showed that, all hormones studied were significant except Tri-iodothyronine (T3). Testosterone as observed in this study was also influenced by age. Male birds unlike their female counterparts at 72 weeks of age recorded higher means value of 4.14 ± 0.52 than those of 21 weeks of age (1.11 ± 0.07). Therefore, the study was able to demonstrate the influence of age and sex on the status of hormones in the Nigerian Local Chicken.
