M-Pesa, a service operated by the mobile phone network Safaricom in Kenya, allows users to deposit money onto their telephone handsets, transfer e-money to another user with a simple text message, and withdraw cash at one of thousands of outlets throughout the country. The system is safer, cheaper, and far faster than the money transfer systems that it replaced. Although only five years old, M-...

Wind farm layout optimisation has become a very challenging and widespread problem in recent years. In many publications, the main goal is to achieve maximum power output minimum wind cost. This may be accomplished by applying single or multi-objective techniques. this paper, we apply objective hill-climbing algorithm (HCA) three evolutionary algorithms (NSGA-II, SPEA2 PESA-II) well-known bench...

BACKGROUND To evaluate the safety of ICSI with epididymal sperm, this study compared children born after ICSI treatment with epididymal sperm and children conceived after IVF and ICSI with ejaculated sperm. Additionally, the results of a multidisciplinary, multicentre follow-up of the children conceived with epididymal sperm at 2 years of age are described. METHODS This follow-up study includ...

This submission will examine how trust can emerge and be sustained in the context of mobile transactions. M-PESA, a mobile banking system in Kenya, will be the focus of this paper. Data will be used from an ethnographic study that was deployed in Kibera—one of Africa’s largest informal settlements. This paper presents research in progress and discusses two main findings. Firstly, interpersonal ...

This chapter examines how trust can emerge and be sustained in the context of mobile transactions. It focuses on M-PESA, a mobile banking system in Kenya, using data from an ethnographic study that was deployed in Kibera—one of Africa’s largest slums. We present research in progress and discuss two main findings. Firstly, interpersonal trust relations between the customers and agents are weak. ...

I n 2007, the leading cell phone company in Kenya, Safaricom Ltd., launched M-PESA, a short message service (SMS)-based money transfer system that allows individuals to deposit, send, and withdraw funds from a virtual account on their cell phones and that is separate from the banking system. M-PESA has grown rapidly, currently reaching more than seven million users, approximately 38 percent of ...

Introduction: We aimed to determine pregnancy and miscarriage rates following intracytoplasmic sperm injection (ICSI) cycles using retrieved epididymal and testicular sperm in azoospermic men and ejaculated sperm in oligospermic and normospermic men. Materials and Methods: This retrospective study was carried out on 517 couples who underwent ICSI. They included 96 couples with azoospermia and 4...

A multifaceted approach to atmospheric aerosol analysis is often desirable in field studies where an understanding of technical comparability among different measurement techniques is essential. Herein, we report quantitative intercomparisons of particle-induced X-ray emission (PIXE) and proton elastic scattering analysis (PESA), performed of fline under a vacuum, with analysis by aerosol mass ...

Objective: The study aimed to compare intracytoplasmic sperm injection (ICSI) outcome of patients with epididymal sperm and testicular sperm in different paternal age with obstructive azoospermia. Methods: We retrospectively studied the records of 177 men with obstructive azoospermia who underwent sperm retrieval for ICSI. 71 cases were performed with testicular sperm aspiration (TESA), 106 cas...

The anthelmintic activity of different extracts of nuts of Semecarpus anacardium were evaluated separately on adult Indian earthworm (Pheritima posthuma). It was found that petroleum ether, chloroform extract of S. anacardium (PESA and CESA, respectively) showed better anthelmintic activities than ethanol (EESA) and aqueous (AESA) extract of it. The anthelmintic effects of PESA and CESA at 10 m...
