Background and objectives: In recent decades, progress of telecommunication industry resulted in public availability to cost-effective cellular mobile hence, boom of base stations of cellular mobile in response to vast public demands. Base stations of cellular mobile are specific source of microwave production in a certain frequency in environment. Antennas are installed on high towers to creat...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
background the malonyl-coa decarboxylase (mcd, ec.4.1.1.9) enzyme regulates malonyl-coa levels. the effect of aerial parts extracts of urtica dioica (ud) on mcd is poorly understood. objectives the present experiment was undertaken to evaluate the effect of ud aerial parts extracts on mcd level. materials and methods in this experimental study, two groups of rats were used: normal and hyperglyc...

The aim of the study is to characterize long-term variability low-level cloud base heights (CBH) in Poland years 1971–2020. Data were used from six weather stations belonging Institute Meteorology and Water Management – National Research (IMWM-NRI), where CBH was first measured using IWO device and, since 1990s, a ceilometer. analysis allowed for data eight observation periods (0000, 0300, 0600...
in this paper, the concept of {sl local base with stratifiedstructure} in $i$-topological vector spaces is introduced. weprove that every $i$-topological vector space has a balanced localbase with stratified structure. furthermore, a newcharacterization of $i$-topological vector spaces by means of thelocal base with stratified structure is given.
