This paper deals with a new concept of logarithmic mean pressure difference (LMPD) to find an accurate mean or true friction coefficient for variable flow in parallel flow channels of the plate heat exchangers while considering the first and the last channel pressure drops. This is analogous to the log mean temperature difference (LMTD) used for the computation of heat transfer in heat exchangers.

In the upper airway, the production of antimicrobial peptides (AMPs) protects against bacteria, viruses and fungi. Previous investigations have revealed downregulated expression of AMPs in different manifestations of allergic disease. In this study, we examined the expression of LL-37, RNase7 and LEAP-2 in tonsillar tissue and studied a possible relation to seasonal allergic rhinitis (SAR).

Apicidin is a potent histone deacetylase inhibitor (HDACI) that selectively binds to histone deacetylases (HDACs) class I and interferes with the deacetylation process, which results in modification of acetylation level of cellular proteins. The aim of the study was to investigate the potential time and dose dependent cytotoxicity of the test compound, Apicidin, in pancreatic cancer cells Capan-1

A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb(-1) of data at a centre-of-mass energy of 7TeV. In units of the elementary electric charge, the top quark charge is determined to be 0.64 +/- 0.02 (stat.) +/- 0.08 (syst.) from the charges of the top quark decay products in single lepton t (t) over bar candidate events.

To examine the trend of urban-rural disparity in obesity prevalence among Chinese children from 1985 to 2010.

Sweden has been a pioneer in the treatment of haemophilia, with the first concentrate available in the 1950s. Treatment has improved over the years to its current state-of-the art. The aim of the current study was to evaluate the long-term outcome of haemophilia in terms of incidence, morbidity and mortality. Patients diagnosed with haemophilia A or B registered at the national haemophilia centres

In this article, we investigate the limitations of organization-centric models for crisis communication in handling place crises. Two distinct types of place crisis are identified as what we respectively term the ‘sudden’ and the ‘ongoing’ type. We point out that place branding traditionally has been used to handle the latter type. We then demonstrate how the inspiration from corporate communicati

Serine proteases of the S1 family have maintained a common structure over an evolutionary span of more than one billion years, and evolved a variety of substrate specificities and diverse biological roles, involving digestion and degradation, blood clotting, fibrinolysis and epithelial homeostasis. We here show that a wide range of C-terminal peptide sequences of serine proteases, particularly fro

During recent years, dipeptidyl peptidase-4 (DPP-4) inhibition has been included in the clinical management of type 2 diabetes, both as monotherapy and as add-on to several other therapies. DPP-4 inhibition prevents the inactivation of the incretin hormones, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1). This results in stimulation of insulin secretion and

A concept that lies at the heart of political rhetoric is that of ‘workfare’. The issue, however, is what types of arguments have been invoked to assert the value of the concept. During the 1960s and 1970s, extensive criticism emerged towards a working life that was said to hinder women’s emancipation; a working life that wasted resources and had a negative impact on the environment; a working lif

Patients with incidentally detected adrenal adenomas may have subclinical hypercortisolism. We hypothesized that impaired renal function could lead to increased cortisol levels in these patients.

In this study, vegetation optical depth from ESA's Soil Moisture and Ocean Salinity (SMOS) satellite mission is combined with other existing remote sensing, meteorological and literature data in order to obtain values of gravimetric vegetation water content (M-g). The methodology combines an effective medium model valid at passive microwave frequencies with a vegetation dielectric constant model.

Abstract in UndeterminedWe characterized the composition and mechanical properties of cortical bone during maturation and growth and in adult life in the rabbit. We hypothesized that the collagen network develops earlier than the mineralized matrix. Growth was monitored, and the rabbits were euthanized at birth (newborn), and at 1, 3, 6, 9, and 18 months of age. The collagen network was assessed b

The present response time study investigated how a hypothesized time-based working memory constraint of 2–3 s affects the resolution of grammatical and semantic dependencies. Congruent and incongruent object relative (OR) and subject relative sentences were read at different presentation rates so that the distance between dependent words was either shorter or longer than 2–3 s. Incongruent OR sent

Little is known about the nature of post mortem degradation of proteins and peptides on a global level, the so-called degradome. This is especially true for non-neural tissues. Degradome properties in relation to sampling procedures on different tissues are of great importance for the studies of for instance post translational modifications and/or the establishment of clinical biobanks. Here, snap

Objective The theory behind the Job Content Questionnaire (JCQ) presumes that the "objective" social environment is measurable via self-report inventories such as the JCQ. Hence, it is expected that workers in identical work will respond highly similar. However, since no studies have evaluated this basic assumption, we decided to investigate whether workers performing highly similar work also resp

Angle-resolved photoemission spectroscopy reveals pronounced kinks in the dispersion of the sigma band of graphene. Such kinks are usually caused by the combination of a strong electron-boson interaction and the cutoff in the Fermi-Dirac distribution. They are therefore not expected for the sigma band of graphene that has a binding energy of more than approximate to 3.5 eV. We argue that the obser

The title compound, Ca5Pd6Ge6, was obtained during a systematic investigation of the Ca-Pd-Ge ternary phase diagram. The crystal structure was determined and refined from single-crystal X-ray diffraction data. It crystallizes in a new structure variant of the Y4PdGa12-type structure (Im3̅m, a = 8.7764(4) Å) that features an arrangement of vertex-sharing body-centered cubes of calcium, Ca@Ca8, with
