On the Self-Organization of Dielectric Barrier Discharges
The present paper contains experimental analysis of the spatiotemporal structure of atmospheric pressure dielectric barrier
discharge (DBD) in a packet-pulse excitation mode widely used as an effective tool for plasma modification of various media. The motivation is the need to optimize the conditions for DBD plasma obtaining with a homogeneous diffuse structure.
It is shown that for a discharge gap of the millimeter range (1–3 mm) in atmospheric air, under certain conditions, a number of new plasma phenomena are possible - the effects of an increase in the density (total number) of filamentary
discharges over time, both unchanged and with a decrease in the area of the filaments, as well as the formation of complex
space-time structures. An interpretation of this phenomenon is proposed. Homogeneous diffuse discharges are obtained in
a standard electrode configuration with a single dielectric

A total of 183 participants (males=89; females=94) were recruited for this study. Data were collected at baseline and at the one-month and three-month follow-ups using a pre-and post-test semi-structured questionnaire. Descriptive data are presented using measures of central tendency and their respective measures of dispersion. No comparative statistical analysis was performed.
Optical Depth Measurement of Self-Reversed Line Emitted from In-Homogenous Plasma in Laser Induced Breakdown Spectroscopy
In this work, an original method is proposed and used for measurement of the optical depth of a self-reversed spectral line. A theoretical approach is utilized in an in homogenous laser induced plasma at local thermodynamic to simulate self-reversed line and then to get the main line profile without self-absorption. In this research, the spatial and temporal evolution of optical depth of two spectral lines of Ca II at 393.4 nm and 396,9 nm is studied. Furthermore, the variation of optical depth versus the concentration of species emitter inside of plasma plume is investigated. In addition, the validity of this method is affirmed during comparison with results obtained by other techniques.

Health Care Workers and Self-Assessed Communication with Language Diverse Patients in the St. Louis Region at the Onset and One Year into COVID-19
Self-assessment (SA) of English speaking ability by patients has been an important reference for the health workforce, and in the past 10 years, research examining health literacy in the USA has continued to emphasize the patient. In the current study, 338 Health Care Workers (HCWs) (82% female and 63% nurses) reported on their current communications with patients (one year into the COVID-19 pandemic) and recalled what communication was like at the onset of the pandemic. Through SA as a way for HCWs to analyze communication, this study investigated information available from community and healthcare facilities, oral communication with patients, and the training of healthcare professionals.
The Combination of Shear Wave Elastography and ELF Test in a Single Score Improves the Diagnostic Specificity for Liver Fibrosis Prediction
Forty patients with CHDs who received liver biopsy to stage fibrosis and 12 normal subjects performed also shear wave elastography (SWE) and ELF-test. We chose two different outcomes for histological fibrosis (F0-F1 vs F2-F4) and (F0-F2 vs F3-F4). ELF-test and SWE were independent predictors, categorized using ROC analysis. Two scores called SCORE1 and SCORE2 were devised.
Factors Affecting Exercise Self-efficacy in Predialysis Chronic Kidney Disease Patients
There was significant evidence to suggest that exercise improves physical function, symptom burden, and quality of life in
predialysis chronic kidney disease (CKD) patients. However, most CKD patients cannot adherence to minimum recommended levels
of exercise.
Relationship between Blood Ethanol Concentration, Ethyl Glucuronide and Ethyl Sulfate and Clinical Signs of Alcohol Intoxication

Relationship between Self-Stigma and Quality of Life among Patients with Schizophrenia
Individuals who are diagnosed with severe mental illness (SMI) such as schizophrenia have always been viewed publicly as being hazardous, violent, aggressive and unpredictable. Their awareness of the fact that they are being discriminated against and stereotyped results in an intense feeling of being devalued by the society, which is referred to as Self-stigma [1,2].

Enteric Duplication Cyst in Infant: Case Report and Literature Review
Congenital malformations can go unnoticed and have an impact on morbidity and mortality in early stages of life being a cause of infant death in some countries [1]. Malformations of the gastrointestinal tract occupy the second place among congenital abnormalities [2]. Along with them, the enteric duplication cyst is an infrequent anomaly difficult to diagnose specially for a non-specialist physician that is not use to attend this kind of pathologies or in hospitals where patients with this entities are infrequent. We present the case of
a 5-month-old patient who underwent intestinal resection due to enteric duplication cyst.
Occurrences of Dairy Calf Mortality and Morbidity and the Associated Risk Factors in Sululta and its Environs, Central Ethiopia
Calf morbidity and mortality are important causes of economic losses on dairy farms worldwide. A cross-sectional study and clinical observation was conducted from November 2016 to April 2017 with the objective of determining calf morbidity and mortality and to investigate the potential risk factors for mortality and morbidity in Sululta and its environs. A total of 312 respondents engaged in market oriented small holder dairying were interviewed using a structured questionnaire survey about their farm and calf management practices and major calf health problems encountered and diseases that causes mortality. The overall magnitude of morbidity and mortality of calves were 31.0% and 58.37%, respectively. The major calf diseases found were diarrhea (69.34%), pneumonia (16.54%), liver fluke (2.4%), bloat (2.0%), joint ill (2.4%) and other cases (8.04%). Risk factors such as weaning age, breed and awareness of colostrums, feeding of calf and overall farm management were included. In this study 80.3% of calf mortality occurs under age 3 month and 19.42% is above 3 month. Based on laboratory examination, Salmonella and E.coli were detected from diarrheic calves. Salmonella found at rate of 2/29 (3.6%) and E.coli found at only genus level. In conclusion, the magnitude of calf morbidity and mortality found in this study were much higher than economically tolerable level and could greatly affect the productivity of the dairy farms through mainly decreasing the availability of replacement stock and production of milk. It is therefore, suggested that implementation of improved calf and farm management practices and proper environmental protection in the study areas would significantly reduce calf mortality and morbidity.

Anodizing for Design and Function
Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.
Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath
The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.
