Characterization of Commercial Solid Waste Stream in Bayelsa State, Nigeria
Abstract:
The problem associated inappropriate management of municipal waste to the ecosystem cannot be overemphasized. This study involved the physical characterization of municipal solid waste streams in 4 commercial dumpsites in Yenagoa Metropolis, using the quartile estimate method. Results showed that out of a total mass of 79.82kg; the individual mass composition was reported for garbage (food) waste 33.32 (39%), paper waste 14.90 kg (40.82%), plastic waste 5.12 kg (6%), nylon 11.01kg (13%), metal 4.31 kg (5%), wood 2.29 kg (3%), electronic 5.69 kg (7%), glass/ceramic 3.48 kg (4%) and unclassified waste whose mass was 4.62kg (5%). Disposal of untreated and unsegregated/uncharacterized waste adverse effect to the environment. It is hereby recommended that the populace to desist from illicit disposal of waste stream. In addition all stakeholders and Government in particular should formulate policies the reduction, reuse and recycling of waste stream.

Marangoni Effect in Second Grade Forced Convective Flow of Water Based Nanofluid
Abstract:
Advances in nanotechnology especially in nanofluids comprising of a typical base fluid saturated with nano-size metallic particles with enhanced thermophysical properties is one of the hot topics in industrial as well as engineering applications of applied mathematics. This article explores the impact of Lorentz forces and Maragoni effect on second grade nanofluid forced convective flow. A two phase model is chosen to validate the nanofluid. Series solutions are achieved through HAM after transformation of PDEs into ODEs. The Brownian motion effect, Thermophoresis and the Marangoni effect are the main influencing factors for present flow model. In addition, the influence of pertinent fluid parameters such as Schmidt number, Magnetic number and Prandtl number on the velocity, temperature and concentration profiles is discussed with the help of graphs. With an enhanced Marangoni factor the hydraulic boundary layer thickness shows enhancement.
International Comparison of Children’s Knowledge, Barriers and Reported Fluid Intake Across the School Day.
Abstract:
To date, no research has explicitly examined children’s knowledge and consumption of fluids at school, particularly during times of exercise (physical education (PE)). Between May and July, 2018, 322 (213 females, 104 males; mean age = 8 years 5 months, SD ± 2 years 1 month) elementary school children from Ireland (n=237) and England (n=85) completed a questionnaire on their understanding of fluid intake and how much they perceived they drank on days when they did/did not participate in PE. Younger (<9 years) English children were most thirsty at the end of the school (68%), compared to younger and older (≥9 years) Irish children who were most thirsty after (38% <9 years; 39% ≥9 years) or ...
Biolarvicidal Potentials of the Methanolic-Leaf-Extracts of Selected Tropical Plant Species
Abstract:
The global impact of malaria and challenges encountered during its control have necessitated the application of multifaceted strategies, including the application of plant-derived agents. Amidst these challenges the proliferation of the vector is becoming hyperendemic in tropical region. This research is focused on the biolarvicidal activities of the methanolic leaf-extracts of
Exploring the Experiences of Partners of Veterans with Mental health Difficulties Attending a Group Psychoeducation Support Intervention: A Qualitative Study.
Abstract:
Research has demonstrated that partners living alongside veterans with mental health difficulties are at high risk of developing mental health difficulties themselves and secondary trauma. A variety of interventions have been developed to support partners. Research to date has relied on quantitative methodologies to evaluate the efficacy of such interventions with less emphasis on learning about the experiences of individuals on the courses. The aim of this qualitative paper was to understand the experiences of partners who engaged in a five-week structured support intervention, ‘The Together Programme’ (TTP) which had been piloted across UK cities. This programme involved tailored psycho educational materials adapted to the needs of veteran’s partners living alongside PTSD. Further the po...

Yeast Species Mediated Bioprocesses and Bio-Products for Biotechnological Application
Abstract:
Yeast as unicellular organism, has shown multiple application due to exhibition of noble ability in its cells. And engineered yeast has found more suitability in bioprocesses application as well as adverse conditions adaptation. Different types of yeast strains showed their best capability to adapt the salt and sugar rich environment with their optimal growth capability. These strains, used as suitable and novel cell factories for production of value added bio-products (via utilization of fermentation processes) and also for different types of bioprocesses. Application of yeast species in biotechnology field, enhanced in current periods, due to conversion of its wild to engineer strain, suitable for bioprocesses utilization and also for different types of biochemical synthesis. Different yeast species identified due to known their genetic, regulatory mechanism and also competitive metabolic pathways. In this regards, different type of engineering approaches (for g...
A Rare Cause of Fever of Unknown Origin: Reverse Shapiro’s Syndrome
Abstract:
Reverse Shapiro’s syndrome is described as unexplained hyperthermia coexisting with agenesis of the corpus callosum. Its pathophysiology dwells on the role of dopaminergic hypersensitivity caused by hypothalamic dysfunction. Until now, only 5 cases have been described in the literature as reverse Shapiro’s syndrome. We present a case of a 6-month-old girl who is now the sixth patient described in the literature. A 6-month-old female patient was admitted to the pediatrics unit for fever of unknown origin. Her fever occurred 2-3 times a day on average between 38°C and 39.5°C, and lasted for 1-2 hours. The fever was not diurnal, and antipyretics or staying in an air-conditioned room had no effect. She also had 2 convulsions during her hospital stay. Cranial magnetic resonance imaging (MRI) was requested owing to the patient’s convulsion history and retarded development. The cranial MRI showed diffuse hypoplasia of the corpus callosum in the midline sagittal ...
Lenalidomide-Induced High Grade Fever in a Patient with Multiple Myeloma: A Case Report
Abstract:
Lenalidomide is a second generation immunomodulatory agent and a potent analogue of thalidomide that is FDA approved mainly for the treatment of multiple myeloma (MM) and transfusion-dependent anemia due to low or intermediate-1- risk myelodysplastic syndromes (MDS) associated with 5q deletion among other indications. Through its action on the immune system, lenalidomide alters the production of different cytokines ultimately resulting in immune activation against tumors. This immune activation may lead to collateral immune toxicities like fever, angioedema, Stevens-Johnson syndrome, tumor flare and others. Here we report a case of lenalidomide-induced high grade fever in a patient with MM and we summarize the literature about the physiology of such reaction and how to mitigate this adverse event.
