Still Arctic? — The changing Barents Sea

The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. Physical conditions in this area are characterized by large seasonal contrasts between partial sea-ice cover in winter and spring versus predominantly open water in summer and autumn. Observations over recent decades show that surface air and ocean temperatures have increased, sea-ice extent has decreased, ocean stratification has weakened, and water chemistry and ecosystem components have changed, the latter in a direction often described as “Atlantification” or “borealisation,” with a less “Arctic” appearance. Temporal and spatial changes in the Barents Sea have a wider relevance, both in the context of large-scale climatic (air, water mass and sea-ice) transport processes and in comparison to other Arctic regions. These observed changes also have socioeconomic consequences, including for fisheries and other human activities. While several of the ongoing changes are monitored and quantified, observation and knowledge gaps remain, especially for winter months when field observations and sample collections are still sparse. Knowledge of the interplay of physical and biogeochemical drivers and ecosystem responses, including complex feedback processes, needs further development.Still Arctic? — The changing Barents SeapublishedVersio

Production of charged pions, kaons and protons at large transverse momenta in pp and Pb-Pb collisions at sNN\sqrt{s_{NN}} = 2.76 TeV

Transverse momentum spectra of $\pi^{\pm}, K^{\pm}$ and $p(\bar{p})$ up to $p_T$ = 20 GeV/c at mid-rapidity, |y| $\le$ 0.8, in pp and Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV have been measured using the ALICE detector at the LHC. At intermediate $p_T$ (2-8 GeV/c) an enhancement of the proton-to-proton ratio, (p + \bar{p})/(\pi^+ + \pi^-\(), with respect to pp collisions is observed and the ratio reaches 0.80 in central Pb-Pb collisions. The measurement of the nuclear modification factors for \(\pi^{\pm}, K^{\pm} and $p(\bar{p})$ indicates that within the systematic and statistical uncertainties they are the same at high $p_T$ (> 10 GeV/c), suggesting that the chemical composition of leading particles from jets in the medium is similar to that of vacuum jets.publishedVersio

THE APPLICATION OF SPEED READING AT INTERMEDIATE LEVEL (A Case Study of Qualitative Research in One of Senior High School at Majalengka)

Muhammad Salim Pajri. 14111330143. THE APPLICATION OF SPEED READING AT INTERMEDIATE LEVEL (A Case Study of Qualitative Research in One of Senior High School at Majalengka) Reading is the important things in education, because people can get knowledge and information from reading. Without reading people cannot absorb many sciences. Here, the researcher use speed reading technique as the tool of analyzing to know the learning and teaching process at intermediate level. Moreover, the aims of this research are (1). To know the teaching and learning process of speed reading. (2). To know students’ attitude towards teaching and learning speed reading. (3). To know overcome of the difficulties of speed reading. Theoretically, is regarding to the reading area, especially in the reading comprehension by using speed reading technique. Practically, the researcher will analyze of speed reading in one of Senior High School at Majalengka which has benefit for teacher to know students’ ability in school. The research finding and discussion told about the teaching and learning process of speed reading at intermediate level. There are three activities of speed reading techniques. (1) Preparation Activity: teacher begins with greetings, deliver material and prepare students by warming up to focuss in learning process. (2) Core Activity: teacher teaches all the materials of speed reading. (3) Follow-up Activity: teacher gives exercise as the activity to know students score of speed reading test. The result of the analysis shows there are 5 students’ attitude towards teaching and learning speed reading. then, the finding shows that (1). Students’ feeling towards teaching and learning using speed reading in general: students like speed reading then also comfortable. (2). Students’ feeling towards the process of teaching and learning speed reading: they get comprehension of this technique. (3). Students’ difficulties in learning using speed reading: there are unfamiliar word on athe text. (4). Students’ feeling towards their comprehension in learning using speed reading: they get purpose in speed reading learning. (5). Students’ motivation in learning using speed reading: they can read books in fast time. It was found the overcome of difficulties of speed reading technique they are the process of the teaching speed reading and response the students’ response towards it, difficulties, disadvantages and teaching using speed reading technique and the result, usefulness, critics, and suggestions of teaching using speed reading technique. From the research that has been done, it can be concluded that there is way to apply speed reading by using steps of speed reading. From this technique will increase students’ ability in reading process. It can help students to read fast and efficient time. Keywords: Reading Comprehension, Speed Reading, Intermediate Leve

Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions

Levels of IL-6 are Associated with Lifetime Attempted Suicide in Alcohol Use Disorder Patients

Background: Patients with alcohol use disorder (AUD) have an increased risk of suicide. Neuroimmunological measures, such as cytokines, are shown to deviate in people with attempted suicide. Few studies have investigated this among AUD patients. Patients and Methods: One-hundred and fourteen patients undergoing residential treatment for AUD were interviewed on lifetime suicide attempts (SA) along with several other background variables and clinical characteristics. Serum blood samples were drawn for analysis of cytokines. Results: Thirty-one patients (27%) reported at least one SA. These patients had more symptoms of current affective disorders and more severe dependence. In bivariate analysis only IL-6 and IL-10 appeared to be associated with lifetime SA but without reaching statistical significance. In multivariate linear regression, adjusting for sex, nicotine use, somatic illness, and the use of antiinflammatory drugs, IL-6 was associated to SA (p = 0.033). Conclusion: The cytokine IL-6 has repeatedly been found to be associated with suicidality. The present study concurs with this role of IL-6 in a naturalistic observational study of AUD patients

Sex-specific factors associated with lifetime suicide attempt among patients with alcohol use disorders

Background Patients with alcohol use disorder (AUD) are at high risk for suicide attempts. Mental health problems along with AUD-related factors may contribute to this increased risk. Studies have shown sex differences in rates and correlates of suicide attempts. Aims The purpose of the study was to examine mental-health-related and AUD-related factors associated with suicide attempt separately in female and male AUD patients. Method We collected information about lifetime suicide attempt and mental-health- and AUD-related factors for AUD in-patients (n = 114; 32 females) receiving rehabilitative treatment. Results The prevalence of lifetime suicide attempt was 27%, and the rate was similar in both sexes. Among females, current depressive symptoms and current post-traumatic stress disorder diagnosis were associated with suicide attempt. In male AUD patients, among the mental-health-related factors, lifetime major depression, panic disorder, social phobia, childhood sexual abuse and antisocial personality disorder were associated with suicide attempt. In addition, AUD-related factors including longer duration of drinking, history of delirium tremens, greater severity of AUD and lower levels of prolactin were associated with suicide attempt in males. Conclusions Our results indicate that suicide attempts in female AUD patients were more mental-health-related, whereas those in males were also related to the severity of AUD. This suggests that a suicide prevention programme for AUD patients would benefit from a sex-based understanding of the risk factors
