This study addresses the research question of how renewable and non-renewable energy consumption (EC) affects economic growth (GDP) in Pakistan over a period 1972-2015. The extends basic production function having labor capital as mainstream variables by adding major sources Pakistan. results Toda-Yamamoto Granger causality test confirm that no exists between GDP force bidirectional gross forma...
OBJECTIVES To investigate the dynamic development of the antimicrobial resistance of Campylobacter jejuni isolated from human diarrhea in Beijing, China, between 1994 and 2010, and to further analyze the molecular mechanisms of erythromycin-resistant strains. METHODS Susceptibility tests were performed on 203 non-duplicate clinical C. jejuni strains against eight common antibiotics using the ...
The point process formed by the sequence of human heartbeats exhibits 1/f-type fluctuations arising from long-duration power-law correlation. We obtain the normalized coincidence rate g2('r) of the underlying point process and demonstrate that the correlation is stronger forpatients with normal hearts than those with heart failure. This is consistent with the greaterrate fluctuations observed i...
BACKGROUND AND AIMS A high serum level of saturated free fatty acids (FFAs) is associated with the development of nonalcoholic fatty liver disease (NAFLD). X-box binding protein-1 (XBP-1) is activated by FFA treatment upon splicing. XBP-1 is a transcription factor induced by the endoplasmic reticulum (ER) stress sensor endoribonuclease inositol-requiring enzyme 1 alpha (IRE1α). However, the rol...
This research deals with a flexible flowshop scheduling problem with arrival and delivery of jobs in groups and processing them individually. Due to the special characteristics of each job, only a subset of machines in each stage is eligible to process that job. The objective function deals with minimization of sum of the completion time of groups on one hand and minimization of sum of the diff...
کرم فلزی در حال حاضر به دو روش استخراج می شود: روش متالوترمیک موسوم به روش گلداسمیت و روش الکترولیز در محلول آبی. این روشها دارای محدودیت هایی مانند قیمت نسبتاً بالای فرآیند و کیفیت نه چندان مناسب محصول هستند. فرآیند جدید ffc کمبریج یک روش احیا مستقیم الکتروشیمیایی در نمک مذاب است که برای به دست آوردن فلز خالص از طریق احیا ترکیبات فلزی به فلزات متناظرشان است که بویژه برای فلزاتی با ترکیبات فل...
Background Forest soils are an important reservoir of organic carbon (OC) and a potential source or sink for atmospheric CO2. Prediction OC stock changes under ongoing climatic management requires spatial explicit base. Knowledge the vertical distribution stocks is very important, since varying soil layers may be affected differently by environmental change. Aim Three-dimensional regionalizatio...
