Human seminal plasma allergy in women is an uncommon phenomenon. A great variety of reactions ranging from local swelling to generalized systemic reactions have been described, and local symptoms have often been misdiagnosed as chronic vulvovaginitis. Sperm barriers, such as condoms, are the most widely advocated method for avoiding these reactions; however this is not acceptable to couples who...

The maximum power point tracking (MPPT) system controls the voltage and the current output of the photovoltaic (PV) system to deliver maximum power to the load. Parameters values were extracted using Newton Raphson method from characteristics of Shell SP75 module. This paper presents a comparative analysis of incremental conductance (IC), and neural network based MPPT techniques. The Artificial...

The complexity of authoring adaptive learning designs and the extra effort and technical knowledge required for course designers restrains the actual application of adaptive course delivery in real settings. Our research works focuses on alleviating the workload for the course designer by applying artificial intelligence techniques that automate part of the design process. We have designed an i...

A distributed model for simulating the land surface hydrological processes in the Heihe river basin was developed and validated on the basis of considering the physical mechanism of hydrological cycle and the artificial system of water utilization in the basin. Modeling approach of every component process was introduced from 2 aspects, i.e., water cycle and energy cycle. The hydrological proces...

objectives in this study the association of phenotypes and activity of butyrylcholinesterase (buche) with serum level of lipid-lipoprotein and apolipoproteins during various phases of menstrual-cycle was determined. methods the study population consisted of 22 healthy women aged 19–25 years with regular menstrual cycles, 26–30 days in length. the serum levels of lipids, apolipoproteins, and buc...

the purpose of this study was to investigate and compare whether the explant supernatants prepared from endometrial tissues during the proliferative phase, secretory phase and early pregnancy differ in immunosuppressive activity. specimens of nonpregnant endometrium from hysterectomies and normal first trimester decidua following elective aspiration termination of pregnancy were obtained. super...

the current regulated particle metric in vehicle emissions is the total mass, while during last decade interest in number size distribution has increased. various international studies on epidemiology and toxicology have reported the adverse effect of the particle matter on public health. the unece group of experts on pollution and energy (grpe) under particle measurement program (pmp) are unde...

STUDY QUESTION Does uterine peristalsis influence the chance of clinical pregnancy in an embryo transfer cycle? SUMMARY ANSWER The uterine peristaltic wave frequency before embryo transfer is inversely related to the clinical pregnancy rates in fresh and frozen-thawed embryo transfer cycles. WHAT IS KNOWN ALREADY Uterine peristalsis participates in regulating fluid migration after mock embr...

Researchers in the discipline of biogeochemistry face an enormous challenge as they perform carbon cycle studies related to global climate change. These include quantifying energy and element flows through the earth system and coupling these flows to the dynamic climate system with the goal of devising models that can be used to predict how these flows might change in the future. In facing this...

The availability of techniques to artificially excite paralyzed muscles opens enormous potential for restoring both upper and lower extremity movements with neuroprostheses. Neuroprostheses must stimulate muscle, and control and regulate the artificial movements produced. Control methods to accomplish these tasks include feedforward (open-loop), feedback, and adaptive control. Feedforward contr...
