FACTORS ENABLING CHILDREN ACQUIRING INDONESIAN AS A SECOND LANGUAGE: AN EAST TIMOR PERSPECTIVE

This study is aimed at investigating factors enabling children acquiring Indonesian as second language (SLA). It was conductedin Suco Comoro, Aldeia 03, Dili, East Timor. The method used in this study was qualitative descriptive. Its research subjectswere children agedten to 15 years old whose first language is Tetun, but they are now acquiring Indonesian. The instruments used to get the data were observationsdan in-depth interviews. The results of the research show that there are two major factors that help the children acquire Indonesian, namely,intrinsic and extrinsic ones. The intrinsic factors are related to the children’s desires or willingness which stimulates them to use Indonesian.These factors encompass motivation, self-confidence, self-esteem and language attitude. In contrast, the extrinsic factors are related to outsidesupports that the children get, namely, from their environmentthat comprises their family relationship, peers, entertainment, and similarities ofsome vocabularies between their first language (Tetun) and Indonesian.It is worth noticing, however, that despite their relatively goodacquisition of Indonesia, they still havesome errors in their Indonesian utterences, a phenomenon known as interlanguage in SLA

Impact Fracture of Composite and Homogeneous Nanoagglomerates

It is not yet clear on whether the fracture characteristics of structured composite capsules and homogeneous nanoagglomerates differ significantly under impact loading conditions. Experimental measurement of impact fracture properties of such small agglomerates is difficult, due to the length and time scales associated with this problem. Using computer simulations, here we show that nanoagglomerates are subjected to normal impact loading fracture within a few nanoseconds in a brittle manner. The restitution coefficient of the nanoagglomerates varies nonlinearly with initial kinetic energy. The fracture of nanoagglomerates does not always happen at the moment when they experience the maximum wall force, but occurs after a time lag of a few nanoseconds as characterised by impact survival time (IST) and IST index. IST is dependant on the initial kinetic energy, mechanical and geometric properties of the nanoagglomerates. For identical geometries of the capsules, IST index is higher for capsules with a soft shell than for these with a hard shell, an indication of the enhanced ability of the soft nanocapsules to dissipate impact energy. The DEM simulations reported here based on theories of contact mechanics provide fundamental insights on the fracture behaviour of agglomerates—at nanoscale, the structure of the agglomerates significantly influences their breakage behaviour

A STUDY ON MASTERING ENGLISH PASSIVE VOICE IN SIMPLE PRESENT, SIMPLE PAST AND SIMPLE FUTURE TENSES BY THE GRADE 12TH STUDENTS OF ESCOLA SECUNDARIA PUBLICA NOBEL DA PAZ, DILI TIMOR-LESTE IN ACADEMIC YEAR 2020

This study is entitled “A study on Mastering English Passive Voice (simple present, simple past and simple future tense) by the Grade 12 Students of Escola Secundária Pública Nobel da Paz, Dili Timor-Leste in the School Year 2020”. The aim of this study is to find out whether or not the grade 12 students master English passive voice as well as to know their mastery level. The population of this study is all the grade 12 students that consisted of four classes and only 30 students who were selected randomly as the sample or respondents. The instrument used for the data collection is a questionnaire in which it comprisis 30 numbers of questions. The methods used in this research are qualitative and quantitative approaches

A survey on the occurrence of resistance to anthelmintics of gastrointestinal nematodes of goats in Mozambique

A survey to study the extent of anthelmintic resistance was conducted in Maputo and Gaza, two of the ten provinces of Mozambique, during February and March 1999. A total of 12 flocks, six in Maputo and six in Gaza, was surveyed. The faecal egg count reduction test was used to assess the efficacy of three anthelmintics most often used in Mozambique, namely albendazole fenbendazole and levamisole. The degree of resistance was calculated using two different methods, and varied according to the method used. Using the formula of Coles, Bauer, Borgsteede, Geerts, Klei, Taylor and Waller (1992), resistance to the benzimidazoles was detected in one flock in Maputo and one in Gaza, and to levamisole in three flocks in Maputo and one in Gaza. When the formula of Dash, Hall and Barger (1988) was used, however, resistance to the benzimidazoles was detected in only one flock in Maputo, and no resistance to levamisole was detected. The 12 farms surveyed were too few for conclusions to be made on the prevalence of anthelmintic resistance in goats in Mozambique as a whole. Therefore, an extensive survey at national level is needed. This study gives evidence, however, that anthelmintic resistance in nematode parasites of goats is an emerging problem, to which special attention should be paid.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Exploring Ligand Binding to Calcitonin Gene-Related Peptide Receptors

Class B1 G protein-coupled receptors (GPCRs) are important targets for many diseases, including cancer, diabetes, and heart disease. All the approved drugs for this receptor family are peptides that mimic the endogenous activating hormones. An understanding of how agonists bind and activate class B1 GPCRs is fundamental for the development of therapeutic small molecules. We combined supervised molecular dynamics (SuMD) and classic molecular dynamics (cMD) simulations to study the binding of the calcitonin gene-related peptide (CGRP) to the CGRP receptor (CGRPR). We also evaluated the association and dissociation of the antagonist telcagepant from the extracellular domain (ECD) of CGRPR and the water network perturbation upon binding. This study, which represents the first example of dynamic docking of a class B1 GPCR peptide, delivers insights on several aspects of ligand binding to CGRPR, expanding understanding of the role of the ECD and the receptor-activity modifying protein 1 (RAMP1) on agonist selectivity
