Many mobility studies (IMS) of electrospray ions with charge states z reduced to unity have shown a singular ability to analyze large protein complexes and viruses, though with wide mobility peaks (fwhm ∼ 20%). Here we confirm that this limitation arises primarily when early charge reduction precedes drop evaporation (suppressing secondary atomization by the usual sequence of many Coulomb explo...

The objective of this paper is to present a framework developed for assisting railway operators into monitoring and controlling the quality of services provided to their passengers. This framework is based on the estimation of 22 indicators, grouped under six criteria, i.e. itinerary accuracy, system safety, cleanness, passenger comfort, servicing, and passenger information. The valuation of th...

Thus, this study aimed to assess patient satisfaction toward clinical laboratory services at Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia. METHODS A hospital-based cross-sectional study was conducte...

OBJECTIVE To introduce an original case-based machine learning (ML) and prediction system Constud and its application on tabular data for estimation of the risk of enterobiasis among nursery school children in Estonia. METHODS AND MATERIALS The system consists of a software application and a knowledge base of observation data, parameters, and results. The data were obtained from anal swabs fo...

BACKGROUND Parasitic infection is the most prevalent among rural communities in warm and humid regions and where water, hygiene and sanitation facilities are inadequate. Such infection occurs in rural areas where water supplies are not enough to drink and use, and in the absence of environmental sanitation, when the rubbish and other wastes increased, and sewage and waste water are not properly...

Purpose: Latrine is a symbol of cleanness. It most to have latrine even for getting basic government facilities. Though the country declared ODF, in reality, it difficult maintain status long. There are pieces evidence that ODF zones reverted open defecation over time. was this context, study carried out explore appropriate latrines be constructed case Mahottari District, Nepal. Design/Methodol...

Background Clean water is an essential part of human healthy life and wellbeing. More recently, rapid population growth, high illiteracy rate, lack sustainable development, climate change; faces a global challenge in developing countries. The discontinuity drinking supply forces households either to use unsafe storage materials or from sources. present study aimed identify the determinants sour...
