Impact of the use of Inorganic Fertilizers to the Soils of the Ebonyi State Agro-Ecology, South-Eastern Nigeria.

There is the fear that long term application of inorganic fertilizers to the soils of the Ebonyi state Agro- ecology could have contributed to the soils productivity constraints.  A study was therefore conducted in the major crop production communities, representing the major soils of the state, to assess the impact of long term use of inorganic fertilizers on the soils.  Soil samples were collected from fifteen different farm locations that have the records of continuous application of inorganic fertilizers and analyzed for their physical characteristics, chemical properties, and microbial population. The Results of the analysis indicated that the soils were very strongly Acidic to strongly acidic (4.0-5.6), whereas exchangeable acidity (EA) was very high across the entire locations. Organic carbon (OC) ranged from low to high (0.51-1.84); Cation Exchange Capacity (CEC) was very low across the locations (1.65-4.5), whereas base saturation ranged from very low to low (42.06-50.10). Total Nitrogen and exchangeable phosphorus ranged from moderate to medium (0.09-0.19 and 5, 70-24.8); potassium, calcium, magnesium and sodium ranged from very low to low (0.05-0.32; 0.86-5.10; 0.30-2.0 and 0.09-0.25) respectively across the locations. The soil microbial populations were however stable and consistent with normal microbial population for natural agricultural soils. The application of lime and complementary use of organic manure and mineral fertilizers were recommended as a sound fertility management strategy for these soils.

Effective Study Habits in Educational Sector: Counselling Implications.

The problem most students have that contributes to their poor performance in tests and examination is lack of proper study habit. For an excellent performance, there is need for the student to form good study habit. A student, who wants to study well, needs to choose a suitable place for his studies. Where to study is as important as what to study and how to go about studying. Productive study habits require learners to prepare personal time-table for themselves allocating a certain length of time for a particular subject, depending on how difficult each subject is. Different methods of studying are well explained here. Key Words: Counselling, Study habits, Reading habits, Educatio

Optimized Industrial Automation Network for Efficient Productivity Using Quality of Service Policy Mechanism (QPM)

In this paper, the complexity of industrial automation network when compared to the traditional IT corporate organization network or campus network, was first described. The challenges and components of industrial automation network have been highlighted. Hence, in order to overcome the challenges in the industrial automation network, the network was optimized by incorporating Quality of Service (QoS) Policy Mechanism (QPM) model in the network design. Existing mechanisms such as transmission control protocol (TCP) to deal with these problems, and the limitations of relying only on TCP were then discussed. The potential to improve the industrial automation network in the perspective of industrial internet of things (IIoT) has been reported in this paper as a further investigation in the future works. Simulation results were presented which showed that the optimized industrial automation network using QoS Policy Mechanism model gives higher performance throughput than the congestion control algorithm of the conventional TCP and the traditional network

Occupational exposure to heavy metals impacts negatively on human health especially on the functionality of the kidneys. This is a cross sectional study designed to assess the kidney function status in individuals who are occupationally exposed to heavy metals in metal forging factory in Nnewi. A total of 39 apparently healthy individuals in cable manufacturing factory workers aged between 19 and 56 years and 79 control subjects (comprising of 39 control subjects from Nnewi (N) and 40 control subjects from Elele (E) respectively) aged between 18 and 44 years were recruited for the study. 5ml of venous blood sample was collected from each subject for the determination of biochemical parameters (potassium, sodium, chloride, bicarbonate, urea and creatinine levels) using standard laboratory methods. Results revealed that there were significant elevations in the mean concentrations of plasma urea, creatinine, sodium and potassium (p<0.05) with a corresponding significant decrease in the mean plasma chloride and bicarbonate levels in the individuals occupationally exposed to heavy metals in metal forging factory (p<0.05), which suggest an impaired renal function in these individuals

Analyzing the progress, pitfalls and prospects for attaining environmental-related sustainable development goals in Nigeria

The year 2020 was the resounding fifth anniversary of the 17 Sustainable Development Goals (SDGs) which have a vision for a safer,  healthier and more prosperous world by 2030. The overall objective of this present research is to analyze Nigeria’s strategies towards ascertaining their progress, pitfalls and prospects for achieving environmental sustainability. The novel Covid-19 pandemic is found out to be closely intertwined with tropical deforestation; hence, humans become exposed to disease pathogens originally found only in wild animals; thereby, depicting consequences for the environmentalrelated SDGs in Nigeria. In addition, Covid-19 measures such as mobility restrictions during lockdowns create major food supply system challenges thereby, affecting availability and accessibility requirements for the attainment of food security (SDG-2) in Nigeria. Hence, the novel Covid-19 is a colossal pitfall retarding progress onenvironmental-related SDGs in Nigeria amid the seven prospects as identified in this research article. Overall, the analysis shows that there is a gap between what can be achieved in the research domain regarding policy-making and implementation of environmental-related SDGs in Nigeria. As a way-forward, future researches are needed to investigate the effectiveness of implementing, monitoring and reporting system of the environmental-related SDGs towards attaining a safer, healthier and more prosperous Nigeria beyond 2030.

Effect Of Depth Of Tillage On Soil Physical Conditions, Growth And Yield Of Sweet Potato In An Ultisol At Abakaliki, Southeastern Nigeria

A study was conducted at Abakaliki, southeastern Nigerian during the raining seasons of 2000 – 2001. The experiment evaluated the changes in some soil physical properties owing to depth of tillage, and the effect on growth and yield of sweet potato. The tillage depth treatments included zero tillage, 10cm, 20cm, 30cm and 40cm tillage depths. The soil physical properties measured were bulk density, penetrometer resistance and soil moisture content. Tilling the soil to depths of 20, 30 and 40cm significantly (P = 0.05) reduced soil bulk density by 13, 15 and 22 % respectively when compared with zero tillage. Penetrometer values were 54, 66, 74 and 78 % significantly higher on 10, 20, 30 and 40cm tillage depth plots than the untilled plots. The gravimetric moisture content was 20, 33, and 43 % significantly higher in the zero than the 20, 30, and 40 cm tillage depths respectively. Tilling the soil significantly increased crop growth and yield compared to untilled soil. Plants on the 40cm tillage depth produced the highest fresh potato tuber yield of 14.5 t ha-1. The study shows that improving soil physical properties, such as reduced bulk density, increased penetration and good drainage, promotes high crop yield.

Difference in frequency obstetric fistula in nigerian and european women

An obstetric fistula is an abnormal opening between the vagina and organs of pelvis.Each year, more than a quarter million women in Nigeria die in pregnancy and childbirth, of those that do not perish, suffer from obstetric fistula (OF).OF caused by of obstructed labor, without timely medical intervention or Cesarean section. During this time, the soft tissues of the pelvis are compressed between the baby’s head and the mother’s pelvic bones. The lack of blood flow causes tissue to die, creating a hole between the mother’s vagina and organs of pelvis

An Overview of the Challenges Facing the International Court of Justice in the 21st Century

The effectiveness of the International Court of Justice (ICJ) is critical for global survival and progress in the 21st century. Unfortunately, after over six decades in existence, the Court’s influence is declining. This work argues that to revitalize the influence and effectiveness of the Court, some vital reforms must be undertaken in the ICJ system. These reforms must address: (1) the process of election and re-election of ICJ judges; (2) the conflict of interest arising from the presence of permanent members of the United Nations Security Council on the Court; (3) the issue of the Court’s compulsory jurisdiction; and (4) the appointment of ad hoc judges under Article 31 of the Statute of the Court. Under the United Nations system, the ICJ is the “principal judicial organ” charged with two main functions, to wit; to assist in the resolution of disputes between states, and to provide advisory opinions to specified international organizations. Although established under the UN Charter, the Court is nevertheless governed by the Charter, the Statute of the ICJ, the Rules of Procedure adopted by the judges and amended from time to time, as well as the Practice Directions adopted in October 2001. Though many rules governing the ICJ strive to create an unbiased and honorable entity, the Court’s legitimacy and impartiality have nevertheless been compromised by issues surrounding the election and re-election of its judges, the UN Security Council’s permanent members’ roles in the ICJ, the Court’s compulsory jurisdiction, and the nomination of ad hoc judges by parties before the Court. After six decades, the ICJ is at a crossroads as it braces to adjudicate the disputes arising in the 21st century. Modern issues concerning environmental protection, terrorism, and human trafficking—among many others—are global problems deserving of attention from a global court. This article argues that the ICJ is ill-equipped to tackle modern international disputes if the jurisdictional and compositional problems outlined above are not remedied, while also offering recommendations for reform. Part I introduces the reader to the inner-workings of the ICJ by discussing the composition of the Court, beginning with an explanation of its roots. Next, Part II critically dissects the challenging preliminary issues of jurisdiction and admissibility. Part III provides an in-depth analysis of the different bases for the exercise of the Court’s jurisdiction, with particular focus on contentious and advisory jurisdiction. Part IV highlights four main challenges facing the International Court of Justice, while Part V concludes by proffering recommendations for a more efficient ICJ in the 21st century. Cite as: 18 Annl.
