Non English speaking background migrant Muslim women and migrant English language provision
The purpose of this study is to define and delineate the factors which influence the decision by non-English speaking background migrant Muslim women to access or not access their eligibility for English language tuition, as set out by current policies governing the eligibility of migrants to participate in Adult Migrant Education programs. As such, the study is of particular interest to both key informants: teachers, community workers, coordinators, and to the target population themselves-Migrant Muslim women. It is also of benefit to those who are concerned with implementing language programs as it will provide them with an understanding of the issues facing Muslim women that may prevent them from accessing such classes. It is also of particular interest because it delves into and explores an• area where much speculation has taken place, but where little research of significance has been directed. The target population is defined as adult (over age 16) Muslim women from a non-English speaking background who are currently residing in the Perth metropolitan area. Two groups within this target population have been included in the study, the first being those women who have accessed migrant language tuition in a formal class setting (excluding those who have accessed the home tutor scheme). The second being those women who have not, with the objective of drawing a typology of the kind of Muslim women accessing classes-age, country of birth, family, socio-economic status, perceived need to learn English, level of education and aspirations and other relevant variables that were brought to light through the research process. Data was collected using both quantitative and qualitative research methods which involved the analysis of figures pertaining to the numbers of women from Muslim countries of birth who have accessed English language classes through the Adult Migrant Education Program in order to arrive at conclusions about the relative absence of Muslim women in these programs. Qualitative data was collected using a structured interview with twenty three women from the target population as well as interviews with three key informants. The purpose of the key informant interviews was to gain an understanding of the external factors accessibility, availability of information and practical considerations such as child care transport and provision of special arrangements that may affect the decision or the ability of Muslim women to attend classes
Investigation of factors affecting reverse-phase high performance liquid chromatography
This study focused on the application of reverse-phase high-performance liquid chromatography (RP-HPLC). RP-HPLC is used for the purification of organic molecules, including pharmaceuticals, natural products, and proteins. We developed a modified version of a United States Pharmacopeia (USP) procedure to separate and purify the chemical components found in Excedrin tablets. The goal was to investigate the relationship between retention time (Tr) and the capacity factor (k\u27) of solutes. By varying the composition of the mobile phase and stationary phase, we experimentally determined the capacity factor of acetaminophen (APAP), caffeine, and aspirin. Our results show that the capacity factor (k\u27) of all solutes increased as the percentage of water in the mobile phase increased. This trend was consistent across all three columns tested. We also observed co-elution of solutes in the C8 and phenyl columns at lower water compositions. For superior separation and baseline resolution of all peaks, we found that the C18 column, as specified in the USP monograph, provided excellent results at all mobile phase compositions tested. Additionally, we investigated the solute retention as a function of mobile phase acidity. When using an acidified mobile phase with the C18 column (3% acetic acid), all solutes exhibited excellent peak shape and symmetry. However, the removal of acid from the mobile phase resulted in poor peak symmetry (non-Gaussian) for solutes containing a carboxylic acid moiety, such as aspirin and benzoic acid. Conversely, more polar solutes like APAP and caffeine maintained their Gaussian peak shape.In conclusion, our study highlights the successful implementation of RP-HPLC for the purification of organic molecules and reveals the relationship between retention time and the capacity factor of solutes. The choice of column and mobile phase composition played a crucial role in achieving optimal separation and peak symmetry
Non-chiral fusion rules, structure constants of D_m minimal models
We present a technique to construct, for unitary minimal models, the
non-chiral fusion rules which determines the operator content of the operator
product algebra. Using these rules we solve the bootstrap equations and
therefore determine the structure constants of these models. Through this
approach we emphasize the role played by some discrete symmetries in the
classification of minimal models.Comment: 30 page
Difusi Gas Radon dari dalam Tanah di Daerah Bengkulu
The aim of this research is to achieve a rough estimation of the radon diffusion coefficient from soil in Bengkulu. The samples were taken from 28 points of different area in Bengkulu. We used a GM tube and LR-115-II detectors to detect the radon concentration. It is found that the average of radon concentration is 136 Bq/m3. While, on the other hand the average of radon diffusion coefficient of soil inÂcrease lenearly with increase of soil depth. We also found that radon exhalation rate from ground surface is 0.88 mBq/m2/s up to 1.51 mBq/m2/s
Stabilisasi Tanah Gambut Palangka Raya dengan Bahan Campuran Tanah Non Organik dan Kapur
Secara umum Kota Palangka Raya memiliki jumlah sebaran tanah Gambut yang cukup besar.Hal tersebut selain menjadi keuntungan tetapi menjadi kerugian dalam bidang Insprastruktur.Tanah gambut memiliki persoalan tersendiri terhadap kekuatan daya dukung tanah dalam menahan beban lalu lintas di atasnya.Usaha perbaikan tanah gambut sering dilakukan dengan metode stabilisasi secara kimiawi yaitu melakukan pencampuran tanah gambut dengan bahan material tanah non organik (tanah granit) dan penambahan kapur dengan variasi 5%, 10% dan 15%. Stabilisasi yang dilakukan bermaksud memperkuat satu atau beberapa parameter dari sifat fisik maupun mekanik dari tanah asli yang ada.Proporsi campuran tanah kapur dan tanah non organik yang digunakan adalah 40% tanah gambut dan 60% tanah non organik.Dari hasil pengujian yang dilakukan yaitu penambahan variasi kapur pada campuran stabilisasi tanah gambut dan non organikterbukti dapat meningkatkan nilai California Bearing Ratio/ CBR yang diperoleh walaupun pada penambahan variasi pertama mengalami penurunan. Nilai CBR campuran tanah gambut dan non organiktanpa kapur diperoleh sebesar 7,79%. Sedangkan pada penambahan kapur 5% nilai CBR turun menjadi 5,89%. Untuk selanjutnya pada penambahan kapur 10% dan 15% secara berturut-turut CBR campuran tanah mengalami peningkatan masing-masing sebesar 9,74% dan 11,59%.Secara umum nilai CBR tanah campuran tanah gambut dan non organik telah memenuhi persyaratan sebagai bahan timbunan pilihan/subbase.Berdasarkan Klasifikasi tanah untuk CBR tanah timbunan pilihan berkisar dari 7% - 20%, kecuali untuk nilai CBR dengan penambahan kapur 5%
