Water Quality, Availability and Potential of Geothermal Energy Utilization, Afra Water, Jordan

Reusing of 3.3 MCM (million cubic meter) of water every year from utilizing thermal water of the hot springs will boost the availability of water at the Dead Sea area. This water represent an additional sources of water for agribusiness in which all available springs and similar sources can follow the same way of successful. In this work the water quality of Afra hot springs was analysed at source

Recommendations for gonadotoxicity surveillance in male childhood, adolescent, and young adult cancer survivors : a report from the International Late Effects of Childhood Cancer Guideline Harmonization Group in collaboration with the PanCareSurFup Consortium

Treatment with chemotherapy, radiotherapy, or surgery that involves reproductive organs can cause impaired spermatogenesis, testosterone deficiency, and physical sexual dysfunction in male pubertal, adolescent, and young adult cancer survivors. Guidelines for surveillance and management of potential adverse effects could improve cancer survivors' health and quality of life. Surveillance recommenda

Soil networks become more connected and take up more carbon as nature restoration progresses

Soil organisms have an important role in aboveground community dynamics and ecosystem functioning in terrestrial ecosystems. However, most studies have considered soil biota as a black box or focussed on specific groups, whereas little is known about entire soil networks. Here we show that during the course of nature restoration on abandoned arable land a compositional shift in soil biota, precede

Abundances of disk and bulge giants from high-resolution optical spectra : II. O, Mg, Co, and Ti in the bulge sample

Context. Determining elemental abundances of bulge stars can, via chemical evolution modeling, help to understand the formation and evolution of the bulge. Recently there have been claims both for and against the bulge having a different [α/Fe] versus [Fe/H] trend as compared to the local thick disk. This could possibly indicate a faster, or at least different, formation timescale of the bulge as

Ignition Sensitivity Study of Partially Premixed Combustion by Using Shadowgraphy and OH∗ Chemiluminescence Methods

Partially Premixed Combustion (PPC) is a promising combustion concept for future IC engines. However, controllability of PPC is still a challenge and needs more investigation. The scope of the present study is to investigate the ignition sensitivity of PPC to the injection timing at different injection pressures. To better understand this, high-speed shadowgraphy is used to visualize fuel injectio

Monetization and the behavior of velocity in Sweden, 1871-1913

The income velocity of money declined sharply in Sweden between the 1870's and the outbreak of World War I. This decline is explained by a monetization process. An account of this process is given focusing on (a) the growth of commercial banking, (b) changes in wage contracts and in labor markets, and (c) changes in exchange arrangements in the markets for goods. A number of proxy measures of the

Urinary incontinence and its management in patients aged 65 and older in orthopaedic care - what nursing and rehabilitation staff know and do

Aims and objectives: To describe what nursing and rehabilitation staff know and do with regard to urinary incontinence and risk of urinary incontinence in patients 65 years or older undergoing hip surgery. Background: Urinary incontinence is a common but often neglected issue for older people. Despite the existence of evidence-based guidelines on how to assess, manage and prevent urinary incontine

A STUDY of multigrid smoothers used in compressible CFD based on the convection diffusion equation

We look at multigrid methods for unsteady viscous compressible flows. We specifically target smoothers that can be used in parallel and without computation of a Jacobian, which are particlarly attractive candidates in the context of Discontinuous Galerkin discretizations. In CFD, a plethora of nonlinear smoothers have been suggested which are hard to analyze. Our methodology is to use a linear mod

The use of the r* heuristic in covariance completion problems

We consider a class of structured covariance completion problems which aim to complete partially known sample statistics in a way that is consistent with the underlying linear dynamics. The statistics of stochastic inputs are unknown and sought to explain the given correlations. Such inverse problems admit many solutions for the forcing correlations, but can be interpreted as an optimal low-rank a

Functional investigations of HNF1A identify rare variants as risk factors for type 2 diabetes in the general population

Variants in HNF1A encoding hepatocyte nuclear factor 1a (HNF-1A) are associated with maturity-onset diabetes of the young form 3 (MODY 3) and type 2 diabetes. We investigated whether functional classification of HNF1A rare coding variants can inform models of diabetes risk prediction in the general population by analyzing the effect of 27 HNF1A variants identified in well-phenotyped populations (n

Predicting glycated hemoglobin levels in the non-diabetic general population : Development and validation of the DIRECTDETECT prediction model-a DIRECT study

Aims/hypothesis To develop a prediction model that can predict HbA1c levels after six years in the non-diabetic general population, including previously used readily available predictors. Methods Data from 5,762 initially non-diabetic subjects from three population-based cohorts (Hoorn Study, Inter99, KORA S4/F4) were combined to predict HbA1c levels at six year follow-up. Using backward selection

Did Monetary Policy Matter? Narrative Evidence from the Classical Gold Standard

This paper investigates the causal effect of monetary policy on economic activity in the United Kingdom between 1890 and 1913. Based on the Romer and Romer (2004) narrative identification approach, I find that following a one percentage point monetary tightening, unemployment rose by 0.8 percentage points, while inflation fell by 2.7 percentage points. In addition, monetary policy shocks accounted

Species-specific temporal variation in photosynthesis as a moderator of peatland carbon sequestration

In boreal bogs plant species are low in number, but they differ greatly in their growth forms and photosynthetic properties. We assessed how ecosystem carbon (C) sink dynamics were affected by seasonal variations in the photosynthetic rate and leaf area of different species. Photosynthetic properties (light response parameters), leaf area development and areal cover (abundance) of the species were

HAMLET – A protein-lipid complex with broad tumoricidal activity

HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells) is a tumoricidal protein-lipid complex with broad effects against cancer cells of different origin. The therapeutic potential is emphasized by a high degree of specificity for tumor tissue. Here we review early studies of HAMLET, in collaboration with the Orrenius laboratory, and some key features of the subsequent development of the HAML

Fracture study of ferritic/martensitic steels using Weibull stress analysis at quasi-static and higher loading rates

Effect of loading rate on cleavage failure probability for ferritic/martensitic steels using Weibull stress analysis is studied. Calibration of Weibull slope for two grades of fusion reactor blanket steels namely, Indian Reduced Activation Ferritic/Martensitic Steel referred as In-RAFMS, F 82H and a non fusion grade modified 9Cr-1Mo steel (P91) are performed for the first time. The calibrated valu

Dermcidin exerts its oncogenic effects in breast cancer via modulation of ERBB signaling

BACKGROUND: We previously identified dermicidin (DCD), which encodes a growth and survival factor, as a gene amplified and overexpressed in a subset of breast tumors. Patients with DCD-positive breast cancer have worse prognostic features. We therefore searched for specific molecular signatures in DCD-positive breast carcinomas from patients and representative cell lines.METHODS: DCD expression wa

Mitochondrial and sarcoplasmic reticulum abnormalities in cancer cachexia : altered energetic efficiency?

BACKGROUND: Cachexia is a wasting condition that manifests in several types of cancer, and the main characteristic is the profound loss of muscle mass.METHODS: The Yoshida AH-130 tumor model has been used and the samples have been analyzed using transmission electronic microscopy, real-time PCR and Western blot techniques.RESULTS: Using in vivo cancer cachectic model in rats, here we show that ske

InxGa1-xP Nanowire Growth Dynamics Strongly Affected by Doping Using Diethylzinc

Semiconductor nanowires are versatile building blocks for optoelectronic devices, in part because nanowires offer an increased freedom in material design due to relaxed constraints on lattice matching during the epitaxial growth. This enables the growth of ternary alloy nanowires in which the bandgap is tunable over a large energy range, desirable for optoelectronic devices. However, little is kno
