Comparative study of levels of mercury in surface soil samples in gold and non-gold mining towns were conducted from Sikakrom of Kenyasi No. 1 and Dadiesoba of Asutsifi District in the Brong-Ahafo Region of Ghana. The mercury concentrations of acid digested dried samples were measured by Cold Vapour Atomic Absorption Spectrometry. Higher levels of T-Hg concentrations were found in surface soil samples at the sites with extensive small-scale “galamsey” mining activities than at the non small-scale “galamsey” mining sites. Levels of Hg in surface soil samples were in the range of 38.56 µg kg-1 to 93.34 µg kg-1 for the extensive small-scale “galamsey” mining sites at Sikakrom of Kenyasi No.1. The concentration levels of T-Hg in surface soil from all the sampling sites are in excess of the WHO tolerable limit of 0.001 µg/kg for soil. The concentration levels of total mercury at Dadiesoba were lower than the WHO tolerable limit of 0.001µg/kg. The influence of the off-shore sea breeze might have affected this observation. Hg levels obtained in this research were higher than the natural background levels of Hg. Obviously; Hg is a major metal pollutant at Sikakrom of Kenyasi No.1. Recovery and Repeatability test were done to check for the accuracy and reproducibility of the analytical method. Regression analysis on surface soil mercury concentrations showed proportionately less deposits at higher distances in 10 cm soil zone. In general, these findings suggest evidence of severe mercury pollution in Sikakrom of Kenyasi No. 1 in the Asutsifi District of the Brong Ahafo Region of Ghana.

We have to make comparison among differential transformation method (DTM) and Variation of Parameter method (VOPM). We provide two examples in order to compare our results and find exact solutions also. The numerical examples show that the DTM is a good method compared to the VOPM since it is effective, uses less time in computation, easy to implement and achieve high accuracy. In addition, DTM has many advantages compared to VOPM since the calculation of Adomian polynomial is tedious. From the numerical results, DTM is suitable to apply for nonlinear problems.

In the pediatric population, the incidence of maxillofacial trauma accounts for 1-15%, out of which mandibular fractures ranges from 5% to 50%. Mandibular fractures occur rarely in newborns and infants, as the ramus and condyle are rudimentary in form at this stage and temporomandibular joint is poorly developed. These fractures (ramus and condyle) are common in adults, but not in children, as in young age the space between the developing condyle and the glenoid fossa cushions a blow to the mandible. The leading causes of these fractures are fall from height (64%), motor vehicle collisions (22%), and sports-related injuries (9%). The examination of facial fractures in pediatric patients is challenging both clinically and radiographically, due to extensive soft tissue injury and developing dentition which obscure the fracture lines. In recent years, the use of CT imaging for radiographic examination of pediatric maxillofacial fractures has been quite helpful as it provides detailed assessment and identification of suspected injuries. The management of maxillofacial fractures in children present with unique challenges and complications such as ankylosis, growth restrictions and associated malocclusion may occur. So, a proper treatment algorithm need to be proposed, stratified by dentition stage in order to optimize outcomes for children.

Fudge is a traditional type of confectionary which is usually very sweet and extremely rich, prepared using sugar, butter, milk and flavor. In the present study, the investigator developed cocoa fudge adopting conventional technology and processing techniques involved roasting, grinding and heating. The developed cocoa fudge samples were analyzed for their physicochemical properties and proximate composition and were compared to those of commercially available fudge samples. The results revealed that there was significant difference in the proximate composition between the developed cocoa fudge samples and the standard fudge samples at p?0.05. No significant difference was observed in most of the determined physicochemical properties of the developed sample. Hence the study ascertain that the sensory qualities may be similar as there was no change in the physicochemical characteristic and would be acceptable by everyone. For wider supply and optimum utilization of cocoa, this conventional technology technique can be adopted.Further it may bring great income to the cultivars and in turn add the economy of our country.

Corrosion on SS-304 in brackish environment. Any compound capable of donating free chlorine ions (Cl -) to an aqueous (water-based) solution has the potential for causing failure in stainless steels. The chlorine ion is extremely electronegative, therefore very reactive with certain compounds and elements. This reactivity is part of its usefulness in certain situations, but becomes a double-edged sword where stainless steel is concerned. Experimental corrosion studies on commercial SS - 304 have been carried out. The experiments were carried in brackish environment with a concentration variation, pH variation and contact time variation. The experiments were carried out by weight loss method, gasometry study and open circuit polarization studies. The post corrosion sample’s micro structures were analyzed with the aid of EDS (Energy dispersive spectroscopy) equipped SEM (Scanning Electron Microscope) EDS (Energy dispersive spectroscopy) instrument to detect the morphology of corrosion by-products. For further verification x-ray diffraction method was also used to detect any possible emerging corrosion by products on the sample’s surface. Experimental results confirmed that SS-304immersed in brackish environment with a variation of concentration , experience very little corrosion. EDS study and x-ray diffraction results indicate that the possible ensuing corrosion by products are Iron oxides, chrome oxides, iron chloride and nickel hydride oxide

The COVID-19 pandemic has shown an impact on sexually transmitted infections. The research aims to understand an overview of CDC's STI surveillance data for 2020 that can provide a general understanding and a comprehensive review of patternsofChlamydia and Gonorrhea infections among men and women.The study conducted an in-depth qualitative research analysis of the CDC's STI surveillance data for 2020. The studyanalyzes particular research questions.What is the difference between reported cases of Chlamydia and Gonorrhea among men and women? How does sexual orientation affect reported cases of Chlamydia and Gonorrhea? What demographics are associated with Chlamydia and Gonorrhea cases? The research analyzes the number of cases of Chlamydi and Gonorrheain fections among men and women, includingsexualorientation, age, ethnicity, and reported cases in healthcare centers.The results of the CDC's STI surveillance data of 2020 have determined that men have a higher number of cases in both infections, and MSM have a higher number of cases in the sexual orientation category. The result differed based on ethnicity, in which females had a significant increase in chlamydia cases compared to men while men had an increased number of gonorrhea cases. African American men and women have shown the greatest number of cases. Non-Hispanic/Pacific Islanders men have a higher number of chlamydia cases compared to women. Overall, the transmission of gonorrhea is higher in men, while chlamydia is seen most in women.Sexually transmitted infections such as gonorrhea and chlamydia may present with unseen consequences. Gender, age, and ethnicity play a vital role in our society in improving health conditions. Limitations may occur within the study. The results may show biases based on the lack of data submission due to restrictions. The inconsistency of recording data could occur based on social distancing guidelines, quarantining, and lack of resources available during the pandemic and guidelines that significantly affect the public. Public health officials utilize the data to determine high prevalence areas to improve policies and guidelines that significantly affect the public.

The clinical manifestations of cardiac myxoma are often non-specific and may delay diagnosis. We report the case of a 53-year-old man who has been presenting for the past four years a recurrent skin rash on his back associated with muscle pain. He was admitted to the emergency room for sudden right-sided hemiparesis and aphasia due to a subacute ischemic stroke at the frontal- parietal and temporal lobes.Echocardiogram revealed a mass in the left atrium suggestive of myxoma. After surgery, the patient remained free of cutaneous symptoms. Atypical manifestations of cardiac myxoma should be considered in order to not delay adequate management.

Air pollutants, including SO₂, H₂S , NO_X and TSP, were measured in Al-Hashimeya town in Zarqa Governorate, where there are three main sources contributing in different degrees to the pollution of air. These are Jordan Petroleum Refinery, Al-Hussein Thermal Power Station, and Al-samra Waste Water Treatment Plant. Data relating to pollution in Al-Hashimeya have been collected from all sources that had measured the level of pollution in this areaduring the period from 2005 to 2009 are presented. The effects of local meteorological conditions were studied by statistical analysis.
The concentration variations in air pollutants are closely related to those in local meteorological conditions. Both temperature and relative humidity have significant negative correlations, whereas wind speed has a significant positive correlation with these pollutants.

Availability, pollution and treatment of water are of major concern of present time. Many micro-organisms are capable for wastewater treatment. In the present study, feasibility of decolorization of dye contaminated effluents collected from different textile industries was examined using Aspergillus tamarii and Aspergillus flavus in batch and continuous reactor. Aspergillus flavus was found to be more efficient than Aspergillus tamarii to decolorize the effluents. Maximum decolorization of 85.3% was observed at optimized pH with 50% diluted effluent sample (ES1) using Aspergillus flavus (pH 4.5) as compared to 82.2% obtained using Aspergillus tamarii (pH 5). Chemical oxygen demand (COD) reduction has been observed to be 75% after decolorization of ES1 using Aspergillus flavus. Scanning Electron Microscopy (SEM) and Gas chromatography–mass spectrometry (GC-MS) analyses strongly supported biosorption as well as biodegradation of dye during decolorization.

A study of delineation of Iron (Fe) and Manganese (Mn) status in soils of Central Research station, Akola was conducted during the year 2006 and 2007. Detailed maps of micronutrient also prepared. Delineation of study area was completed with help of global positioning system and for predicting available cationic micronutrient status extraction with chelating agent such as di ethylene triamine penta acetic acid (DTPA) is used. The soils of Central Research Station were found 20 per cent deficient in iron and 7 per cent deficient in manganese. While the available micronutrient status of Central Research Station soils was found as iron 0.12 to 16.32 and manganese 0.32 to 16.78.
