The objective of this study is to evaluate the influence different periods abstinence on conventional sperm parameters, DNA integrity and oxidative stress. A prospective comparative that was performed between March 2018 2021. total 449 human semen samples were obtained from patients performing an advanced exploration at a private ART clinic. Exclusion criteria included azoospermia. Sperm parame...

Dynamic software updating provides many benefits, e.g. in runtime monitoring, runtime adaptation to fix bugs in long running applications, etc. Although it has several advantages, no quantitative analysis of its costs and revenue are available to show its benefits or limitations especially in comparison with other software updating schemes. To address this limitation in evaluating software upda...

In article number 2100463, Ranjan Singh, Weili Zhang, Xiaojun Wu, and co-workers successfully fabricate novel nonlinear THz metasurfaces with nanometer capacitive gaps large size experimentally realized precise frequency tuning. The gigantic resonant electric field enhancement in nanogaps induces carrier multiplication silicon substrates, resulting conductivity increase the gap regions of metas...

in today’s complex, dynamic and ever changing modern environment, all companies need to design and use strategies helping them to improve continuous performance, because in such a competitive environment, those companies which keep pace with changing and dynamic conditions of competitive market are able to survive. this study was conducted using descriptive – correlational methodology. the stud...

Seminolipid (sulphogalactosylalkylacylglycerol), the glycolipid that is specific for mammalian germ cells, is located exclusively in the outer leaflet of the sperm plasma membrane. In this study the lateral distribution of seminolipid on sperm heads has been investigated by indirect immunofluorescence labelling and detection with digital imaging fluorescence microscopy. In freshly ejaculated sp...

This paper examines comprehensive evaluation of aperiodic time-based checkpointing and rejuvenation schemes maximizing the steady-state system availability in an operational software system. We consider two kinds of maintenance policies: checkpointing prior to rejuvenating (CPTR) and rejuvenating prior to checkpointing (RPTC). These schemes are complementary from each other to schedule checkpoi...

The focus on alternative energy sources has increased significantly throughout the last few decades, leading to a considerable development in the wave energy sector. In spite of this, the sector cannot yet be considered commercialized, and many challenges still exist, in which mooring of floating wave energy converters is included. Different methods for assessment and design of mooring systems ...

This dissertation shows that existing functional tests of software features can be used by a developer unfamiliar with the software system to identify source code relevant to those features as well as understand why the source code is relevant. There have been prior techniques to locate features in source code which can be roughly broken down into techniques that use static analysis and those t...

The development of male infertility increased rapidly worldwide, which coinciding with the epidemic of obesity. However, the impact of weight abnormalities on sperm quality is still contestable. To assess the correlation between BMI and sperm parameters, we searched relevant articles in PubMed, Embase, Web of science, and Wanfang database published until June 2015 without language restriction. ...
