Fluoride is known to contaminate groundwater in many countries notably India, Sri Lanka, China, rift valley countries in East Africa, Turkey and parts of South Africa. Sporadic incidence of high fluoride content in groundwater has been reported in 19 states and union territories across the country (CGWB 2010; Pol 2012). The fluoride occurrences in top aquifer system are endemic in many parts of Andhra Pradesh, Tamil Nadu, Karnataka, Gujarat, Rajasthan, Punjab, Haryana, Bihar and Kerala (Agarwal et al. 1997; Latha et al. (1999); Gopalakrishnan et al. (2012). The toxicity of fluoride is generally influenced by high ambient temperature, alkalinity, calcium and magnesium contents in drinking water (BIS 1991). High level of fluoride posses serious health hazards to humans and irreversible damage to plants. The present study was carried out to assess the fluoride concentration of groundwater in the selected villages around Khapa town of Nagpur district.

There can be no doubt that landuse profoundly affects the quality of water in streams, rivers, lakes and shallow aquifers. However, the task of finding specific cause - effect relationships between different landuses and Water Quality (WQ) is one of the most important ecological challenges of out times. At the present time, few tested procedures are available to study the landuse and Non-Point Source (NPS) pollution impacts on WQ. One methodology which offers considerable promise is the use of statistical analysis of landuse and WQ data from selected regions. Facilitating the systematic application of statistical procedures, in the present investigation, regression equations have been developed between landuse and WQ parameters. The results of the study indicated that landuse can account for up to 45% of the observed variation in mean nitrates, 39% of the observed variation in mean phosphates, 58% of the observed variation in mean fluoride concentration, 46% of the observed variation in mean COD concentrations and 72% of the observed variation in mean potassium concentrations.

The storage process, in some way, has a direct influence on the production and status of the derived final product. It was possible to verify in this case study that the storage system of the company is deficient, needing improvements, especially when entering the raw material for production. Such problems, such as impurities, broken and burned grains, are generated in the warehouse itself, due to lack of prudence and coordination. Findings that contradict the objective of storage that is the conservation of the particularities of the grains and that may detract from the attributes of the end product in terms of taste, physical and chemical characteristics and visual conditions. Among the possible causes of the disturbances are the lack of maintenance of the machines, inefficient aeration and thermometry gauging. As a suggestion, besides the improvements on the mentioned problems, the implantation of management and strategy of inventories, of programs and quality control, development of the producing agents, planning and methods of solution of problems. The decline in the quality of the raw material, corn, can result in chain effect, damaging the final product, thus damaging the financial results of the organization.

Purpose Misophonia is a sound tolerance disorder condition in certain sounds that trigger intense emotional or physiological responses. While some persons may experience misophonia, a few patients suffer from misophonia. However, there is a dearth of literature on audiological assessment and management of persons with misophonia. The purpose of this report is to discuss the assessment of misophonia and highlight the management option that helped a patient with misophonia. Method A case study of a 26-year-old woman with the complaint of decreased tolerance to specific sounds affecting quality of life is reported. Audiological assessment differentiated misophonia from hyperacusis. Management included retraining counseling as well as desensitization and habituation therapy based on the principles described by P. J. Jastreboff and Jastreboff (2014). A misophonia questionnaire was administered at regular intervals to monitor the effectiveness of therapy. Results A detailed case history and audiological evaluations including pure-tone audiogram and Johnson Hyperacusis Index revealed the presence of misophonia. The patient benefitted from intervention, and the scores of the misophonia questionnaire indicated a decrease in the severity of the problem. Conclusions It is important to differentially diagnose misophonia and hyperacusis in persons with sound tolerance disorders. Retraining counseling as well as desensitization and habituation therapy can help patients who suffer from misophonia.

School Learning

So far, in implementing school strategies, they tend not to utilize Information and Communication Technology (ICT), despite the availability of ICT resources available. Stages of strategic management are needed to generate the vision, mission, objectives, policy, program, budget, and procedures as well as control and evaluation process as an effort to utilize ICT to improve school quality. Based on the interpretation and the results of the study, it is concluded that schools have organized stages in strategic management that enable schools to have a quality profile. The impact of effective utilization of ICTs for schools is the achievement of effective school management, as per the National Education Standards, which is characterized by effective planning, implementation, control, and evaluation of school ICTs.The purpose of this study is to get a general description, describe, and reveal the Strategic Management of Information and Communication Technology Utilization to Improve the Quality of School Learning in Ciledug Al Musaddadiyah Vocational High School and Garut 1 Vocational High School, both on environmental analysis, strategic formulation, implementation and strategic evaluation. The research method used in this research is the case study method, because the problems studied occur in the place and situation of Ciledug Al Musaddadiyah Vocational School and Vocational High School 1 Garut. The use of case study models in this study is based on the consideration that to provide an overview of the strategic management activities of the use of ICTs carried out at vocational high schools with the ultimate goal of being able to improve the quality of school learning. Based on observations in the field of SMK 1 Garut and SMK Al Musaddadiyah Ciledug Garut is one of the public schools and private schools that have these advantages.

The image quality of Cone Beam Computed Tomography has enough diagnostic value in differentiating between haemorrhage, embolic materials and the arteriovenous malformation nidus to facilitate physicians to decide for further management of the patient.
