Knowledge-Gap among Doctors in the Niger Delta Region of Nigeria about Sexual and Reproductive Health

Emmanuel Columba Inyang-Etoh, Anyiekere Morgan Ekanem, Anietimfon Sunday Akpan
Objective: Sexual and reproductive health the way it is currently conceptualized is a new discipline in medicine, and many medical doctors whose responsibility is to provide information and service to promote this essential component of health do not fully understand the concept. This study was designed to determine the level of knowledge of Nigerian doctors about sexual and reproductive health. Methods: Partly pre-coded questionnaires were administered to a cross section study of doctors for se...

Open Channel Flow over a Permeable River Bed

Godwin Christopher Ezike Mbah, Cyril Ifeany Udogu
This paper presents results of a modeled open channel flow through a porous media (River). In the model, we considered water as an incompressible fluid; the flow as steady and uniform; the system is assumed to be isothermal and the flow pattern is laminar. We have solved the resulting Brinkman equation using analytical method. By some mathematical operation, the momentum partial differential equation (PDE) was reduced to ordinary differential equation (ODE) and the resulting equations are solved...

Cumulative Perturbations Affecting a Spacecraft on a Mars Equatorial Orbit from the Waxing and Waning of the Polar Caps of the Planet

Jean-Pierre Barriot
We demonstrate in this paper that periodic variations of the J2 gravity coefficient of a planet induce small cumulative perturbations on a given family of circular equatorial orbits, and that these perturbations could be measurable with current radiosciences technology. For this purpose, we first consider a Poincaré expansion of the Newtonian equations of motion. Then, by using Floquet’s theory, we demonstrate that, unlike the excitation mechanism, the perturbations are non- pe...

Pattern of Vaginal Discharge and Associated Demographic Characteristics among Female Patients Seen at a Gynaecology Clinic in Northern Nigeria

Mohammed-Durosinlorun Amina, Muhammad-Idris Zainab, Abubakar Amina, Ojabo Augustine, Adesiyun Adebiyi
Background: Vaginal discharge is a common gynecological symptom seen among women provoking anxiety and fear of sexually transmitted infections (STIs). Methods: This was a hospital based retrospective study done from November 2008 to March 2013. Records of 969 patients presenting to the gynaecology clinic with symptoms of “vaginal discharge” were retrieved and relevant data on demographics, discharge characteristics and frequency, associated risk factors and symptoms, as well as investigations we...

The Cause of the Gleissberg Cycle: A Working Hypothesis

Sebastián Martín Ruiz
Gleissberg cycle is a recurring climatic period of 80 years duration. It is usually attributed to the influence of the Sun. In this article, we present a new hypothesis for the possible cause related to the magnetic field of Jupiter.

On the Intrinsic Precession of the Perihelion of Mercury

Barbaro Quintero-Leyva
The longitude of the perihelion advance of Mercury was calculated for the two and ten-body problem by using a correction to the balance between the force given by the Newton 2nd law of motion and the Newton gravitational force. The corresponding system of differential equations was solved numerically. The correction, that expresses the apparent mass variation with the body speed, has a trend that is different from those that usually appear in the electron theory and in the special the...

Interrelations between Mathematics and Experiment in the Present Structure of Quantum Electrodynamics

Eliahu Comay
The electromagnetic interaction of the hydrogen atom is used as an experimental device and the data prove that bound fields and radiation fields are different physical objects. A further analysis proves that there is no direct interaction between radiation fields and there is no self-interaction of fields of an elementary pointlike charge. Therefore, bound fields and radiation fields should be treated differently and radiation fields emitted from two different sources should be treated separatel...

Linguistic Methods to Detect Lies

Daoshan Ma, Dong’ao Lin
The present manuscript mainly introduces three linguistic methods to detect lies, namely Hand- writing Analysis, Voice Stress Analysis, and Non-Verbal Analysis and the application of these linguistic deception detection approaches in various fields, such as law enforcement, intelligence agencies, and forensic context. These major deception detection techniques are illustrated by examples based on graphology, psycho-physiological stress response, and non-verbal communication studies.

Adult Infectious Disease Consultation over a 10-Year Period in a Community-Base Teaching Hospital

Eyassu Habte-Gabr
This is a descriptive review of a large number (5606) of both in and outpatient adult infectious disease consultation from a major teaching hospital over extended period (2001-2010). The purpose of the study is to get spectrum of ID and determine trends in occurrence by age and sex. The common inpatients ID consultations were SSTIs, septicemia, osteomyelitis and that for outpatient by far most common were HIV/AIDS in over a third, followed by SSTI, osteomyelitis. There was equal distribution by ...

The Correlation between Mothers with Low Birth Weight History and Body Mass Index Leptin Levels, and Preeclampsia

Aryani Aziz, Johanes C. Mose, Anita Deborah
Preeclampsia (PE) is one of the complications of pregnancythat significantly increases maternal and fetal mortality and morbidity. Mothers who were born as low birth weight (LBW) babies have risks for PE that are 2 - 3 times higher than maternal birth weight ≥ 2500 g. LBW history of the mother is also correlates with the incidence of metabolic syndrome later in life including incresed of body mass index (BMI), hyperlipidemia, hypertension, stroke type 2 diabetes and cardiovascular accident (CVA)...
