Phonon sidebands of color centers in hexagonal boron nitride

Low temperature photoluminescence spectra of a color center in hexagonal boron nitride are analyzed. The acoustic phonon sideband can be described by a deformation coupling proportional to strain to a phonon bath that is effectively two dimensional. The optical phonon band is described by Frohlich coupling to the LO-branches, and a deformation coupling proportional to lattice displacement for the TO-branch. The resonances expressed in the optical band vary from defect to defect, in some emitters, coupling to out-of-plane polarized phonons is reported.Comment: 7 pages, 4 fig

Spices and condiments: safer option for treatment of hyperlipidemia

Hyperlipidemia is a lipoprotein metabolic disorder characterized by high serum Low density Lipoprotein and blood cholesterol. It is a major risk factors in the development and progression of atherosclerosis that eventually lead to cardiovascular diseases. This poses a major problem to majority of society because of the close correlation between cardiovascular diseases and lipid abnormalities. There are various features which are associated directly or indirectly as etiological factors viz. heredity, age, obesity, sex, diet, physical inactivity, hypertension, lifestyle disorders and various stress factors. For alleviation and treatment there are many ways such as allopathic medications, alternative systems like Ayurvedic, Diet control, lifestyle discipline etc. Recently Spice therapies are seen useful and effective. In India, Ayurveda and other Indian literature mentions the use of various plants and spices. Spices in diet are useful as they play effective role in the functioning of various body systems such as gastrointestinal, cardiovascular and nervous system. Along with proper food habits, diet which contains variety of spices which have been proved as hypolipidemic, can be effective in controlling hyperlipidemia. Spices used in day-to-day life as food, can also be used in the treatment of various human ailments. Along with the taste, flavor, colour and preservative property, spices also possess hypolipidemic effects. This review is focused mainly on the beneficial hypolipidemic effect of five spices (Dill, Garlic, Fenugreek, Ginger, Coriander) in the management of hyperlipidemia. This article is based on the traditional knowledge, mechanism of action for hypolipidemic activity and some experimental scientific studies done to support the use of these spices in the management of hyperlipidemia

Study of three-nucleon dynamics in the dp breakup collisions using the Wasa detector

An experiment to investigate the ^{1}H(d,pp)n breakup reaction using a deuteron beam of 300, 340, 380 and 400 MeV and the WASA detector has been performed at the Cooler Synchrotron COSY-Jülich. As a first step, the data collected at the beam energy of 340 MeV are analysed, with a focus on the proton–proton coincidences registered in the Forward Detector. Elastically scattered deuterons are used for precise determination of the luminosity. The main steps of the analysis, including energy calibration, particle identification (PID) and efficiency studies, and their impact on the final accuracy of the result, are discussed

MS in Asian countries

This paper reviews all available English language literature on MS from Asian countries published between 1970 and 2005. Although limited data are available, the review reveals that western Asia--including the Middle East--has the highest prevalence of MS across the continent, and that MS in Asia largely resembles conventional MS in western countries. Opticospinal MS (a distinct clinical entity from conventional MS) is more common in eastern Asian regions. Larger epidemiological and genetic studies, with more complete ascertainment in various Asian populations, are needed so that we can understand the diversity of Asian MS

Knowledge of and Adherence to Health Advice among Adults with Diabetes in Libya

Background: Non-adherence to medical and health care advice is a common problem, though reasons for non-adherence can differ across different groups and societies as well as between individuals. Objective: to examine diabetes knowledge among people with both type1 and type2 diabetes in Libya and explore any other factors that enhance adherence to treatment and management of the condition. Methods: A cross-sectional survey design was used to collect data from adults with type1 or type2 diabetes who have been diagnosed for 12 months or more, in Benghazi Diabetes Centre, which is one of the oldest and largest diabetes registries in Libya. A total of 855 participants were asked to fill in two questionnaires; the Michigan Diabetes Knowledge Test to investigate the level of diabetes knowledge and the Confidence in diabetes Self-care Scale to assess self-efficacy. For the purpose of the study descriptive statistics and inferential statistical tests were conducted. Results: Diabetes knowledge is very poor especially among females and those classed as illiterate within the sample. The Mean HbA1c of 9.39 was higher than the recommended levels. Four variables namely knowledge about diabetes, duration of illness, family history and self-efficacy significantly predicted levels of HBA1c. Conclusion: Based on the above findings two different programmes of diabetes education would be recommended. The first programme of education would focus primarily on those with inadequate levels of knowledge about diabetes, particularly female and people with long duration diabetes. The second programme would be for both healthcare professionals and people with type 1 and type2 diabetes, which would consider the psychological factors that are involved in the process of diabetes management

Deuteron-deuteron collision at 160 MeV

The experiment was carried out using BINA detector at KVI in Groningen. For the first time an extensive data analysis of the data collected in back part of the detector is presented, where a clusterization method is utilized for angular and energy information. We also present differential cross-sections for the (dd$\rightarrow$dpn) breakup reaction within \textit{dp} quasi-free scattering limit and their comparison with first calculations based on Single Scattering Approximation (SSA) approach.Comment: 6 pages, 4 figures, presented at Jagiellonian Symposium 2015 in Krakow, PhD wor

Experimental study of three-nucleon dynamics in proton-deuteron breakup reaction

Proton–deuteron breakup reaction can serve as a tool to test stateof- the-art descriptions of nuclear interactions. At intermediate energies, below the threshold for pion production, comparison of the data with exact theoretical calculations is possible and subtle effects of the dynamics beyond the pairwise nucleon–nucleon interaction, namely the three-nucleon force (3NF), are significant. Beside 3NF, Coulomb interaction or relativistic effects are also important to precisely describe the differential cross section of the breakup reaction. The data analysis and preliminary results of the measurement of proton-induced deuteron breakup at the Cyclotron Center Bronowice, Institute of Nuclear Physics, Polish Academy of Sciences in Kraków are presented
