Esophageal cancer (EC) is the eighth most common cancer globally in 2012 and predominantly occurs in the man (Enzinger and Mayer, 2003; Conteduca et al., 2012). EC is classified mainly into two types, esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma, accounting for 60-70% and 20-30% of all EC cases, respectively. In a previous statistical study it was reported that the nu...

BACKGROUND AND OBJECTIVES To investigate the association between demographic characteristics and eating competence (EC), "the behaviour and attitudinal conceptualization of eating", among elderly Taiwanese. METHODS AND STUDY DESIGN Random questionnaire survey. Overall, 564 questionnaires were analyzed, and independent t-tests, analysis of variance, chi-square tests, were used to compare the d...

Elemental carbon (EC) in size-segregated aerosol samples were determined at five urban, one suburban, and one rural locations in the Pearl River Delta region in South China during 2006–2008 period. The size modal characteristics of EC were different at the urban and suburban/rural locations. The urban EC had a dominant condensation mode with a mass median aerodynamic diameter (MMAD) in the 0.36...

Abstract The present study investigates the characteristics of carbonaceous species like organic carbon (OC) and elemental (EC) in ambient total suspended particulates (TSP) at Bhimtal (high altitude urban, 1413 m asl) Pantnagar (lowland 224 sites Kumaon province Uttarakhand, Indian Himalayan region during winter summer 2017–2018. Ambient TSP samples were taken on quartz filters with high volum...

Nucleic acid-dependent polynucleotide adenylytransferase (EC 2.7.7.19) and ribonucleic acid polymerase (EC 2.7.7.6) have been partially purified from maize tissues (Zea mays L.) utilizing ammonium sulfate precipitation and batch diethylaminoethylcellulose chromatography. The technique is applicable to the simultaneous processing of up to eight samples of plant tissue and affords a rapid and rep...

this study was conducted to evaluate the responses of two greenhouse tomato cultivars to nutrient solutions' electrical conductivity (ec). two cluster type greenhouse tomato cultivars (razan and ergon) were grown in perlite in a glasshouse hydroponic system. the grown plants were daily fed with either constant ec nutrient solutions (ecs 2, 3 ds m-1) or nutrient solutions of alternatively c...
