abstract this study investigated the predictability of variables from a motivational framework as well as individuals qualities to predict three non-linguistic outcomes of language learning. gardners socio-educational model with its measures has been used in the current study. individual qualities presented in this study include (1) age, (2) gender, and (3) language learning experience. the...
An in situ investigation of thermal decomposition reactions of trimethylindium (TMIn) in a vertical, upflow chemical vapor deposition reactor has been carried out using Raman spectroscopy. Monomethylindium (MMIn) and atomic indium were detected along with the precursor TMIn using N2 as the carrier gas. Atomic indium was identified by the peak at 2215 cm, which is equal to the difference between...
The coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome 2 (SARS-CoV-2), dates back to December 29, 2019, in Wuhan, China. It quickly spreads like wildfire all continents the following months. In Guinea, first case of COVID-19 and death were reported respectively on March 12 April 16, 2020.

Context. Debris discs around main-sequence stars indicate the presence of larger rocky bodies. The components of the nearby, solar-type binary αCentauri have higher than solar metallicities, which is thought to promote giant planet formation. Aims. We aim to determine the level of emission from debris around the stars in the αCen system. This requires knowledge of their photospheres. Having alr...

Climate change and variability, has embarked societies in Zanzibar to rely on horticulture (i.e. watermelon production) as an adaptive measure due unpromising situation of commonly used agricultural yields. Currently, there is either no or scant information that describes the influence climate changes variability production Zanzibar. Thus, this study aimed determine quantity The both primary se...
This paper investigates the annual and seasonal variations in minimum maximum air temperature (Tmin Tmax) precipitation over Kashmir valley, Northwestern Himalayas from 1980–2019 by using innovative trend analysis (ITA), Mann-Kendall (MK), Sen’s slope estimator methods. The results indicated that Tmin Tmax are increasing for all six climatic stations, whereas four of them exhibit significant tr...
