Abstract: In this article the author draws attention to the importance of parents and community involvement in improving academic learning of the pupils. Pupils' academic accomplishment is not a unilateral process: the parents and educators must actively facilitate the education of pupils. This should function in four levels: instructions at school, instructions at home, school governance and community services. Getting parents involved in the educational progression is a Herculean task since parents and teachers live in different life worlds that are separated by psychological barriers. Here the author tries to address some of the issues and offer tangible proposals to overcome the prevailing barriers.
Foreign Exchange Derivative Pricing with Stochastic Correlation  [PDF]
Topilista Nabirye, Philip Ngare, Joseph Mungatu
Journal of Mathematical Finance (JMF) , 2016, DOI: 10.4236/jmf.2016.65059
Abstract: Financial markets are known to be far from deterministic but stochastic and hence time dependent correlation tends to suit the markets. We price for European Options by using three dimensional assets under stochastic correlation. The pricing equations under constant correlation and stochastic correlation are derived numerically by using finite difference method called the Crank Nicolson method. We compare the pricing equations when the correlation is stochastic and constant by using real data from emerging financial markets, that is, exchange rates data for Kenya as the domestic currency and South Africa as the foreign currency. Pricing equation for the European option with stochastic correlation performed better than that with constant correlation.
Synthesis of Poly(APP-co-EGDMA) Particles Using Monomers Derived from Cashew Nut Shell Liquid for the Removal of Cr(III) from Aqueous Solutions  [PDF]
Joseph Wilson, Joseph Yoeza Naimani Philip, James Epiphan Gabriel Mdoe
Open Journal of Organic Polymer Materials (OJOPM) , 2014, DOI: 10.4236/ojopm.2014.41005

This work was aimed at synthesizing Cashew Nut Shell Liquid (CNSL) based polymer particles for adsorption of Cr(III) ions from aqueous solutions. Natural CNSL was used as a starting material in synthesizing amino pentadecylphenols (APP). This was achieved through isolating anacardic acid from the CNSL via calcium anacardate procedure, followed by hydrogenation of the alkenyl side chains, and subsequently decarboxylating the product to form 3-pentadecylphenol, which was then nitrated and reduced to a mixture of APP. APP were co-polymerized with ethylene glycol dimethacrylate (EGDMA) to form poly(APP-co-EGDMA) particles. The chemical structures of the synthesized compounds were confirmed by Fourier Transform IR and 1H-NMR. The co-polymer particles were characterized by Scanning Electron Microscopy (SEM) to establish their morphological properties. The prepared co-polymer particles were found to have-NH loading of 46 mmol/g and a maximum adsorption capacity for Cr(III) ions of 16 mg per g of dry polymer particles. The spent polymer particles were recoverable and reusable.

Corrosion Inhibition of Amino Pentadecylphenols (APPs) Derived from Cashew Nut Shell Liquid on Mild Steel in Acidic Medium  [PDF]

Materials Sciences and Applications (MSA) , 2016, DOI: 10.4236/msa.2016.78036
Abstract: In this study, corrosion inhibiting properties of amino pentadecylphenols (APPs) derived from Cashew Nut Shell Liquid (CNSL) on mild steel in aerated 0.10 M HCl at 303 K were studied using Electrochemical Impedance Spectroscopy (EIS) and potentiodynamic polarization measurements. Both methods indicated the potential of a mixture of amino pentadecyphenols to serve as a corrosion inhibitor in mild steel in 0.10 M HCl. Corrosion inhibition efficiencies were observed to increase with increase in the inhibitor concentration, with maximum corrosion inhibition of about 98% at inhibitor concentration of 600 ppm. The adsorption of the inhibitor on mild steel surface was found to obey Temkin adsorption isotherm, signifying physical adsorption of the inhibitor molecules on mild steel surface.
Penile metastasis of prostatic adenocarcinoma: Report of two cases and review of literature
Joe Philip, Joseph Mathew
World Journal of Surgical Oncology , 2003, DOI: 10.1186/1477-7819-1-16
Abstract: Two such patients are discussed here having received differing therapeutic regimes, pointing out the necessity for standardised palliative treatment rather than radical therapy.Management of patients with penile metastases from carcinoma of the prostate should emphasise improving quality of life with palliative treatment rather than radical therapyMetastasis to the penis is rare, despite rich vascularisation and complex circulation. These most commonly arise from the prostate and the bladder [1,2]. It is a debilitating near terminal condition at presentation with a dismal prognosis. Conservative management is generally advocated with emphasis on improvement of quality of life. Therapeutic modalities used include radical penile amputation and radical radiotherapy. We discuss two patients who underwent differing treatment; the presenting features and symptomatology of all other cases reported in the literature have been reviewed.A 92-year-old man presented as an emergency with bleeding per urethra. Multiple painful 2 × 2 cm hard nodules were seen around the coronal sulcus (PSA = 299 ng/ml). He had had a primary well-differentiated adenocarcinoma of the prostate diagnosed 11 years previously. His treatment included bilateral orchidectomy and cyproterone acetate. A clinical diagnosis of penile metastases was made. In view of the multiple small nodules, urethral ulceration, local obstructive symptoms and severe penile pain; surgery was considered instead of external beam radiotherapy. A subtotal penectomy with perineal urethrostomy was performed. The surgery was straightforward with remarkably little blood loss, probably a result of genital atrophy secondary to long-term androgen withdrawal. Histology confirmed the presence of metastatic moderately well differentiated prostatic adenocarcinoma (Figure 1) extending through the length of the penis and into the glans and spreading to the surface of the skin at the corona with vascular and lymphatic permeation.

Journal of Mathematical Finance (JMF) , 2016, DOI: 10.4236/jmf.2016.62027
Abstract: Precise recognition of a time series path is important to policy makers, statisticians, economists, traders, hedgers and speculators alike. The correct time series path is also a key ingredient in pricing models. This study uses daily futures prices of crude oil and other distillate fuels. This paper considers the statistical properties of energy futures and spot prices and investigates the trends that underlie the price dynamics in order to gain further insights into possible nuances of price discovery and energy market dynamics. The family of ARMA-GARCH models was explored. The trends depict time varying variability and persistence of oil price shocks. The return series conform to a constant mean model with GARCH variance.
Oxidant Sensing by Protein Kinases A and G Enables Integration of Cell Redox State with Phosphoregulation

Sensors , 2010, DOI: 10.3390/s100402731
Abstract: The control of vascular smooth muscle contractility enables regulation of blood pressure, which is paramount in physiological adaptation to environmental challenges. Maintenance of stable blood pressure is crucial for health as deregulation (caused by high or low blood pressure) leads to disease progression. Vasotone is principally controlled by the cyclic nucleotide dependent protein kinases A and G, which regulate intracellular calcium and contractile protein calcium sensitivity. The classical pathways for activation of these two kinases are well established and involve the formation and activation by specific cyclic nucleotide second messengers. Recently we reported that both PKA and PKG can be regulated independently of their respective cyclic nucleotides via a mechanism whereby the kinases sense cellular oxidant production using redox active thiols. This novel redox regulation of these kinases is potentially of physiological importance, and may synergise with the classical regulatory mechanisms.

Abstract: Agrochemicals are generally recognized as a significant factor in enhancing the ability to meet Ghana’s need for sufficient, safe and affordable food and fiber, however, increased usage have led to environmental deterioration. In Ghana agriculture and public health sectors remain the major contributors of pollutants into the environment. This is a systematic review of studies done in Ghana to give an integrated picture of agrochemicals especially pesticides exposure to humans, animals, plants, water, soil/sediment and atmosphere in Ghana. Although the widespread usage of agrochemicals in Ghana has contributed immensely to increased food supply and improvement in public health, it has caused tremendous harm to the environment. Water bodies, fish, vegetables, food, soil and sediment have been found to be pesticide contaminated. There is considerable evidence that farmers have overused agrochemicals especially pesticides. It is evident from biological monitoring studies that farmers are at higher risk for acute and chronic health effects associated with pesticides due to occupational exposure. Furthermore the intensive use of pesticides involves a special risk of for field workers, consumers and unacceptable residue levels in exportable products may serve as barrier to international trade. This review will set the future course of action of different studies on agrochemical usage and pesticide exposure in Ghana.
In Situ Behavioral Response of Common Loons Associated with Elevated Mercury (Hg) Exposure
Joseph J. Nocera,Philip D. Taylor
Ecology and Society , 1998,
Abstract: Common Loons (Gavia immer) in Nova Scotia, Canada have the highest blood mercury (Hg) concentrations of any loon population in North America. Previous studies have shown that exposure to varying levels of Hg in prey is associated with changes in pre-nesting adult behavior. We report here the first association of sublethal blood Hg contamination with changes in behavior of Common Loon young. As Hg levels in their blood rise, the amount of time that chicks spend brooding (by back-riding) decreases (P = 0.004) and time spent preening increases (P = 0.003). The sum increase in energy expenditure is not being compensated for with expected increases in feeding rates or begging. We suggest that such altered time-activity budgets may disrupt the energetic balance of young. Our results show that variation in time spent back-riding is associated with changes in fledging rates. Adult behavior did not significantly vary with Hg, but results are suggestive that an association may exist. We also show that monitoring the time-activity budgets of very young chicks can serve to indicate the effects Hg concentrations in their blood. We confirm the hypothesis that loons and other upper trophic level predators could be at risk from elevated levels of bioavailable Hg. This may help to explain the chronically low productivity of such contaminated sites as Kejimkujik and allow for more focused management initiatives.

Abstract: This study investigated the impact of Fadama II Project on the standard of living of the people of Dadin-Kowa community of Yamaltu-Deba Lcal Government Area of Gombe State. Data were generated using the structured questionnaire using simple descriptive and cost/return analysis.The result revealed that most farmers were females (67%) and had informal education (48%).Furthermore, about (50%) of the sampled farmers are aware of modern technology transfer through extension agents and majority of the farmers used the benefit derived from Fadama Irrigation Project to acquire assets (35.8%), educate children (29%). The production and cost analysis revealed that irrigation farming is profitable. However, the 10% counterpart contributions by the beneficiaries and elites interference were the major mplementation problems among others. To fully actualize the potentials of agriculture and the rural community through Fadama II, there is need to review the 10% beneficiary contribution, ensure prompt release anddisbursement of funds/input through associations thereby reducing elites interference and a complete re-orientation package in form of public enlightenments, talks and seminars should be embarked upon in order to change the attitudinal disposition of youths in the study area towards agriculture.
