THE EFFECT OF STORAGE ON VITAMIN C STABILITY OF LOCALLY GROWN FRUITS IN BRUNEI DARUSSALAM

Objective: Since humans are incapable of producing vitamin C, we obtain our daily requirement of vitamin C from dietary sources such as fruits. It is a common household practice to refrigerate fruits or fruit juices (4°C - 5°C). The main aim is to understand the effect of storage and temperature on the vitamin C level of locally available fruits or fruit juices.  Method: Four locally grown fruits were selected: pomelo, papaya, tomato, watermelon and one imported fruit from United State of America, orange to test for vitamin C stability following refrigeration at 4°C. Vitamin C was measured at Day 0, 1, 2, 3 and 7. Determination of vitamin C was carried out by an accredited Association of Official Agricultural Chemists (AOAC) indophenol method.  Results: At Day 0, orange had the highest level of vitamin C (58.2±0.00 mg/100ml) while watermelon contained the least (6.7 ± 1.27 mg/100ml). The vitamin C in orange and pomelo was stable for at least 24 hours and all fruits experienced continuous loss until the end of storage period, day 7. Watermelon recorded the highest vitamin C loss of 82.1%. Conclusions: Therefore, it is best to consume fresh fruit juice within 24 hours, particularly for watermelon in order to obtain maximal vitamin C

DIAGNOSIS OF CUSHING’S SYNDROME; BIOCHEMICAL INVESTIGATIONS

Cushing’s syndrome remains an uncommon diagnosis with majority of non-specific and few specific clinical features suggestive of the condition. Results of biochemical investigations are often affected by confounding factors making diagnosis of Cushing’s syndrome difficult and localisation of the disease even more challenging. Careful assessment of the individual patient and use of the most suitable test in that patient may allow improved outcome in diagnosing and localising the condition to devise an appropriate management plan.Key words: Cushing’s syndrome, hypercortisolism, dexamethasone suppression test, Pseudo-Cushing’

Identifikasi Mikroba dari Lendir Estrus dan Deteksi Kebuntingan Sapi Kawin Berulang di Sleman, Yogyakarta

Repeat breeding is condition of cows that have normal or near normal estrous cycles but fail to become pregnant after several insemination. In this study, we investigated the microbes in the cervical and vaginal mucus of beef cattle and dairy cows that experience repeat breeding and detected the pregnancy after the third or more artificial insemination. A total of 14 beef cattle and 6 dairy cows that experience repeat breeding in the cattle herd in the Yogyakarta region of Indonesia were used as samples in this study. Cervical and vaginal mucus samples were collected using plastic sheet when the cow was re-estrus. The samples were put into the 5 ml Brain Heart Infusion Broth for bacterial isolation and identification. Pregnancy examination was carried out on day 45 after artificial insemination using ultrasound method. Bacteria that could be isolated and identified from cervical mucus and vaginal mucus of beef cattle and dairy cows included Bacillus sp., Staphylococcus epidermidis, Staphylococcus aureus, and Pseudomonas sp. Some cows detected positive in pregnancy examination even though the bacteria were presence in the cervical and/or vaginal mucus. There was various composition of bacteria found in the cervical mucus and vaginal mucus, of beef cattle and dairy cows with repeat breeding in livestock groups in Yogyakarta. The presence of bacterial in the cervical and vaginal mucus during estrus was not always become the causes of failed pregnancy

Talak dalam perspektif Sayyid Quthb dan Quraish Shihab

INDONESIA: Penafsiran terhadap ayat-ayat hukum tidak pernah berhenti bertransformasi dalam kajian ilmu tafsir. Begitupun penafsiran yang terjadi di kalangan para mufassir baik klasik hingga kontemporer sangat beragam dalam menginterpretasikan ayat-ayat al-Qur’an. Khususnya yang berkaitan dengan ayat- ayat hukum talak.Perbedaan penafsiran tersebut, diakibatkan beberapa faktor. Di antaranya perbedaan dalam penggunaan metode dan beragam karakteristik yang mereka miliki. Begitu halnya dengan penafsiran Sayyid Qutbh dan Quraish Shihab dalam menginterpretasikan ayat-ayat talak. Rumusan masalah dalam penelitian ini adalah bagaiamana penafiran ayat- ayat talak menurut Sayyid Qutbh dan Quraish Shihab, bagaimana metode penafsiran keduanya dalam menginterpretasikan ayat-ayat talak, dan persamaan serta perbedaan penafsiran keduanya dalam mengimplementasikan sebagai konstribusi pemikiran keilmuan di bidang hukum keluarga khususnya talak. Metode penelitian ini menggunakan pendekatan deskriptif-comparatif, jenis penelitian adalah normatif karena penelitian ini sifatnya literatur. Paradigma yang digunakanadalah scientific paradigm (Paradigma Ilmiah) dengan melakukan penelitian pada buku, yang lebih dikenal dengan libraryresearch. Berdasarkan hasil penelitian, dapat ditarik kesimpulan bahwa Sayyid Qutb dalam penafsirannya, memandang hukum talak sebagai manhaj Ilahi yang telah diatur sesuai dengan fitrah manusia. Talak sebagai solusi atau jalan terakhir yang diberikan dalam mengatasi persoalan suami-istri. Sedang menurut Quraish Shihab, bahwa baik rujuk maupun cerai, semua harus dilakukan dengan ma’ruf, yakni dengan keadaan yang baik serta terpuji. Di sini, menceraikan digarisbawahi dengan ma’ruf, sedang cerai dengan ihsan.Metode yang digunakan Sayyid Qutbh ialah dengan metode analitis atau lebih dikenal dengan Tahlili. Tafsir ini berupa tafsir sastra, dengan karakteristik tafsir Adabiijtima’i. Sedang Quraish Shihab meggunakan metode maudhu’i. dengan menafsirkan sesuai dengan urutan masa turunnya surat-surat al-Qur’an.

A customizable, multi-stage multi-criteria decision analysis approach for material-supplier selection problem in SMEs : a case study of insulated housing products

This research develops a multi-stage multiple criteria decision making (MCDM) approach for combined supplier-selection, material selection problems. The method has been exemplified through an industrial case study on the development of insulated skirting products. Namely, a Canadian distribution company has been long supplying the Canadian market with skirting products for manufactured homes, but recently has had issues with their overseas material supplier, particularly due to increased exchange rates. Hence, it has desired to shift their supply stream to a local manufacturer. There exist a large number of potential manufacturers that would be suitable for this new partnership. It has been crucial to scrutinize the decision alternatives systematically in order to rank and allow for the optimal selection of the supplier(s) and their skirting products. When manufacturing suppliers are changed for a business, a natural consequence is that the end product’s material properties would also change, hence the need for a rigorous material testing as part of a multiple criteria decision making process. A step-by-step procedure has been developed here that combines supplier and material selection sub-decisions in order to find the most suitable alternative, using a hybrid of multiple criteria optimization techniques. The procedure accounts for the required decision accuracy and time-sensitivity measures that a production manager would face under different decision scenarios. The case study shows that if the company’s business situation is time-critical and the decision accuracy may not be of primary concern, a simple non-compensatory MCDM method would suffice. Otherwise, more structured compensatory methods should be employed. The criteria proposed for the case study have been selected based on the company staff feedback. The presented methodology is customizable and may be applied to other similar supplier decision making problems. Correlation analysis has also performed to ensure the independence of the quantitative material criteria, as required per assumptions of the standard MCDM methods.Applied Science, Faculty ofEngineering, School of (Okanagan)Graduat
