Abstract Thermal therapeutic pools in most countries are operated in a manner similar to swimming pools: with water circulation, filtration and disinfection. However, in some countries, including Hungary, therapeutic pools are traditionally not treated this way, in order to preserve the therapeutic qualities of the water. However, dilution and frequent water replacement applied in these pools are often insufficient to ensure adequate microbial water quality, posing a risk of infection to the bathers. In the present case study, the impact of water treatment (including chemical disinfection by hypochlorite or hydrogen peroxide) was investigated on the therapeutic components of the water in seven Hungarian spas of various water composition. Microbial quality was improved by both disinfectants, but hypochlorite reduced the concentration of the therapeutic components sulfide, bromide, and iodide ions by 40–99%, and high levels of disinfection by-products were observed. Hydrogen peroxide only affected sulfide ion (91% reduction). Other technological steps (e.g., transport or cooling by dilution) were found to have significant impact on composition, often outweighing the effect of disinfection. The current case study demonstrated that thermal waters may be treated and disinfected with minimal loss of the therapeutic compounds, if an adequate treatment procedure is selected based on the water composition.

Primary Canine

Relevance. The article studies the primary canine premature extraction as the cause of three-dimensional (sagittal, transversal, vertical) bone underdevelopment in the area of the extracted tooth. The research is relevant as there are insufficient data in the scientific literature on this topic and the prevalence of premature primary canine extraction for therapeutic and orthodontic indications is high.Materials and methods. The present case study developed a special technique for bone volume measurement in all planes by CBCT.Results. Several CBCTs of one patient over the period of three years were analyzed according to the suggested technique. The calculations demonstrated significant sagittal and vertical bone loss.Conclusions. The results of the research allowed us to conclude that premature extraction of the primary canines leads to the significant sagittal and vertical bone loss. Besides, no increase in the intercanine distance was detected despite the patient’s growth spurt.

The Impact

Aripiprazole is the first medication approved by the FDA as an add-on treatment for MDD. The impact of aripiprazole on the response to HIV is unknown. The patient we report on was diagnosed HIV-positive in 1997 and has been treated with antiretroviral therapy since then. In 2008, we diagnosed resistant major depression, hypochondria, and panic disorder. On that occasion, blood tests showed a significantly reduced CD4 count and a positive viral load. We treated this patient with aripiprazole and citalopram. Mood, somatic symptoms, and occupational functioning progressively improved. The last blood examination showed an increase in the CD4 count and a negative viral load. On the basis of the present case study and the review of the literature concerning the effects of psychotropic agents on viral replication, we suggest that the use of aripiprazole in HIV-infected subjects warrants further research.

The Village

Abandoned village land is used for community welfare, one of which is used to build people's markets. Where the people's market is useful for utilizing existing facilities, as well as providing opportunities for the surrounding community to increase income as well as creating jobs for people who are unemployed. And from there the Village Officials create a people's market to be rented out to local people who want to trade. The purpose of this study was to determine the application of the ijarah contract and the impact on the welfare of the community. This study uses a qualitative method with a case study approach that aims to obtain information directly from informants based on the current case. The results of this study indicate that the application of village land leases in Bulusari Village is in accordance with Islamic law even though at the time the agreement took place there was no third party to be a witness. As for the impact on Village Officials as land administrators and tenants, this system can improve the welfare of indicators of religion, life, mind, descent and property.

Quantitative Case Study

A recent shift in the conceptualization of both depressive and anxiety disorders supports the notion that these disorders may best fall under a single classification of “emotional disorders.” This understanding has resulted in the development of various transdiagnostic cognitive behavioral therapy (tCBT) protocols to address underlying core pathology shared by emotional disorders. While there is evidence to suggest tCBT is effective in reducing co-occurring depression, research into the efficacy of face-to-face tCBT has generally focused on the delivery of tCBT to individuals with predominantly anxiety diagnoses. The current case study aims to expand the research by examining the impact of group tCBT for individuals with a principal depressive diagnosis. A session-by-session explanation of a 12-week group tCBT protocol designed to treat a heterogeneous group of individuals diagnosed with an emotional disorder is provided in detail and accompanied by a quantitative case study of a recently delivered treatment group. The case study demonstrates the feasibility and pragmatic application of the group tCBT treatment approach. Data presented support the continued research of transdiagnostic interventions for the treatment of emotional disorders and justify future randomized controlled trials to further evaluate the presented intervention.

Transnational Company

The intent of the current case study of a Japanese multinational company is to document and understand the process of developing a transformational (quantum change producing) leadership style in its fast-track leaders in the South West Asia region. The researcher got an opportunity to observe the process of leadership development training that was delivered over a period both through virtual and face-to- ace mode. In the current case study, no instruments were used and therefore no objective data were available to gauge the impact of the training program. However, training partners had identified some of the training outcomes on participants such as 1) participants displayed initiatives to introduce change and persisted that change throughout the completion of the vision with positivity, 2) they examined self-strengths and weaknesses and demonstrated the ability to improve through feedback, and 3) they identified the business, financial, leadership, entrepreneurial, and other challenges at hand and designed the robust plans to overcome those. In short, the researcher can conclude with a reasonable confidence that the training program delivered online could be a success, particularly when it is blended with a FTF experience at some point.

There is nothing that cannot be related directly or indirectly to anything else, and it is this nightmare that is horrifying. There seems to be no precedent for this sort of chaos in the languages of the world… (Traill 1974:251)Regularity of phonological change is considered a basic principle of historico-linguistic reconstruction. In 1876 A. Leskien of the Leipzig school of neogrammarians formulated the postulate of sound change occurring without exception, meaning “that if one assembled all the facts, and analyzed them accurately and thoroughly, one could state exceptionless principles or laws for the development of language” (Lehmann 1973:87). However, it has since been argued on the basis of empirical research that languages are never in complete balance and that, therefore, change is not necessarily constant, nor parallel among groups speaking different languages. Various reasons have been found to account for irregularities in language: the impact of one language on another, the effect of children acquiring their language, etc. Yet before we enter into any etiological discussion of irregular or unstructured phonological change, the area of investigation for the present case study must be introduced, and the characteristic of the problematic nature of the case sketched.

Abstract Elevated tanks are an integral part of the water supply networks. This paper highlights the effect of elevated tanks' location and size on the transient pressures resulting from the sudden failure of pumps. A comparison between the impact of elevated tanks and air vessels on the water hammer was also performed. The Bentley HAMMER model was first validated then applied to analyze the unsteady flow within an actual distribution network. The results display that the elevated tanks have a considerable effect on the surge pressures, where they improve the extreme pressures effectively at and around them, but they cannot fully protect the system from the water hammer risks, as there are still relatively large negative pressures at some distant junctions. Besides, as the tank capacity increases, the surge pressures increase slightly. In our case study, the best location of the elevated tank is at the network extremity and then at the pumping stations, since the minimum pressures improve by 67 and 54%, respectively. Although the present case study may differ from other supply systems, the obtained results can provide an indication of the elevated tanks' role in alleviating undesirable water hammer effects.

Unique Potential

ABSTRACT The impact-generated hydrothermal system at Vargeão Dome, Brazil, is a unique potential analogue for impact-generated hydrothermal systems on Mars. Its evolution can be understood through thermodynamic modeling, for which one of the necessary parameters is the composition of the involved water. The exact water composition for Vargeão at the time of the impact is unknown, and, moreover, the effect of this uncertainty is often underestimated in thermodynamic modeling. Here, the effect of initial water composition was tested by using a randomized set of initial solutions for thermodynamic modeling of the evolution of the Vargeão Dome impact-generated hydrothermal system. It was found that even small changes in composition could affect the precipitation of common minerals like calcite and quartz. Therefore, it is necessary to perform a sensitivity analysis for any thermodynamic model in which the initial solution is poorly constrained. Subsequently, the found effects were used to constrain water compositions for the Vargeão Dome system at the time of the impact, by eliminating randomized solutions of models precipitating different minerals from those observed in reality. Using a simple set of rules, it was possible to constrain the total amount of dissolved solids between 6 and 2000 mg/L, as well as provide approximate boundaries for all individual elements present in the solution.

The Impact

ABSTRACT Fraud is a serious and growing international problem, and can greatly affect a company's performance. The current case highlights the impact that culture can have on corporate corruption through the culture of a specific organization, as well as through the broader culture of a society. In this case, Russian NorthOilService (NOS) acquired 98 percent of the shares of the near-bankrupt Kazakh drilling company, South MunaiGas (SMG) in 2007. NOS management realized that SMG's weak financial standing was caused by corporate fraud and corruption, among other factors. Unfortunately, NOS was unable to prevent the new management team of SMG from committing fraud, despite NOS's anti-fraud efforts after acquisition. This actual case study focuses on the accounting and other frauds perpetrated by the SMG management team and the anticorruption measures implemented by NOS. It addresses fraud, bribery, corruption, and misappropriation of assets through inappropriate procurement procedures, in a cultural environment differing substantially from U.S. corporate contexts. This case is suitable for use in auditing, corporate governance, and fraud examination courses.
