Abstract: Background. Haemodialysis (HD) catheter-related bloodstream infections (CRBSIs) are a major complication of long-term catheter use in HD. This study identified the epidemiology of HD CRBSIs and to aid in the choice of empiric antibiotics therapy given to patients with HD CRBSIs. Methods. Patients with HD CRBSIs were identified. Their blood cultures were performed according to standard sterile technique. Specimens were sent to the microbiology lab for culture and sensitivity testing. Results were tabulated in antibiograms. Results. 18 patients with a median age of 61.0 years (IQR: 51.5–73.25) were confirmed to have HD CRBSIs based on our study criteria. Eight (44.4%) patients had gram-negative infections, 7 (38.9%) patients gram-positive infections, and 3 (16.7%) patients had polymicrobial infections. We noted that most of the gram-negative bacteria were sensitive to ceftazidime. Unfortunately, cloxacillin resistance was high among gram-positive organisms. Coagulase-negative Staphylococcus and Bacillus sp. were the most common gram-positive organisms and they were sensitive to vancomycin. Conclusion. Our study revealed the increased incidence of gram-negative organism in HD CRBSIs. Antibiogram is an important tool in deciding empirical antibiotics for HD CRBSIs. Tailoring your antibiotics accordingly to the antibiogram can increase the chance of successful treatment and prevent the emergence of bacterial resistance. 1. Introduction Chronic kidney disease (CKD) is a major public health burden [1]. The contribution of CKD to the global burden of disease may be underestimated due to the lack of significant importance in certain kidney disease classifications and failure to realize the relationship of CKD with cardiovascular disease [1]. The prevalence of end-stage renal disease (ESRD) is increasing exponentially worldwide. USA, Japan, and Taiwan had the highest rate of prevalence of ESRD [2]. In Malaysia, dialysis is the main modality of renal replacement therapy. There were about 26,000 patients on dialysis in 2011 with the prevalence of 900 per million populations [3]. Haemodialysis (HD) accounts for about 89% of dialysis patients and most of them were accepted to centre HD [4]. Unfortunately, not all patients enter HD program with a native vascular access. Many patients still presented late and HD access catheter, either cuffed or noncuffed catheters, is needed to perform HD. The use of HD catheter had increased from 3% in 2002 to 8.1% in 2011 of all vascular accesses [5]. We cannot argue that HD catheter plays a very important role in the treatment of
On the maximal temporal amplitude of down stream running nonlinear water waves

Abstract: This paper concerns with the down-stream propagation of waves over initially still water. Such a study is relevant to generate waves of large amplitude in wave tanks of a hydrodynamic laboratory. Input in the form of a time signal is provided at the wave-maker located at one side of the wave tank; the resulting wave then propagates over initially still water towards the beach at the other side of the tank. Experiments show that nonlinear effects will deform the wave and may lead to large waves with wave heights larger than twice the original input; the deformations may show itself as peaking and splitting. It is of direct scientific interest to understand and quantify the nonlinear distortion; it is also of much practical interest to know at which location in the wave tank, the extreme position, the waves will achieve their maximum amplitude and to know the amplitude amplification factor. To investigate this, a previously introduced concept called Maximal Temporal Amplitude (MTA) is used: at each location the maximum over time of the wave elevation. An explicit expression of the MTA cannot be found in general from the governing equations and generating signal. In this paper we will use a Korteweg - de Vries (KdV) model and third order approximation theory to calculate the approximate extreme positions for two classes of waves. The classes are the wave-groups that originate from initially bi-chromatics and Benjamin-Feir (BF) type of waves, described by superposition of two or three monochromatic waves. We show that for initially bi-chromatics signals, the extreme position does not depend on the phases of the mono-chromatic components. For BF signals, however, the phases of the mono-chromatic components influence the extreme position essentially. The theoretical results are verified for the case of bi-chromatics with numerical as well as experimental results; for BF signals we use an analytical solution called the Soliton on Finite Background (SFB) for comparison.

e-BANGI : Journal of Social Sciences and Humanities , 2010,
Abstract: Umum menyedari bahawa melabur dalam saham amanah merupakan suatu langkah bijak dalam usaha meningkatkan pendapatan. Persoalannya, apakah semua lapisan masyarakat di negara ini mempunyai ketersampaian kepada saham amanah tersebut, terutamanya mereka yang tergolong dalam kumpulan berpendapatan rendah. Kajian ini menilai sejauhmana masyarakat desa, iaitu pesawah padi mempunyai ketersampaian terhadap saham amanah yang terdapat di negara ini. Kajian turut mengenalpasti faktor-faktor penggalak dan penghalang yang mempengaruhi ketersampaian mereka. Dapatan kajian mengesahkan bahawa, meskipun kebanyakan golongan petani ini mempunyai pengetahuan umum mengenai saham amanah, tetapi ketersampaian dan penglibatan mereka secara langsung dalam pelaburan tersebut adalah agak terbatas. Tarikan kadar dividen yang tinggi dikenalpasti sebagai faktor penggalak utama mereka menyertai saham amanah. Manakala, dua faktor utama yang menghalang mereka daripada terlibat dalam saham amanah ialah kekurangan pendapatan dan kurangnya pendedahan terhadap pelaburan saham amanah itu sendiri. Secara keseluruhannya, penglibatan pesawah-pesawah padi terbabit dalam saham amanah adalah amat rendah dan terbatas. Fenomena ini cukup jelas apabila kebanyakan mereka kurang berkemampuan untuk mempertahan dan meningkatkan nilai pelaburan mereka.

Abstract: Daylight and solar radiation data are important parts of building design process. However, many of the fundamental daylight and solar research studies used by architects and engineers in Indonesia are based upon data taken in other parts of the world. In order to investigate daylight availability data in low latitude/tropic area which are extremely lacking at the present stage, a measurement of daylight and solar radiation was done in Makassar. Cloud ratio is known as a most practical and convenient parameter to specify the real sky conditions. This paper describes the analysis of sky luminance by cloud ratio method which are obtained from the data measured during the period January - December 1995. Abstract in Bahasa Indonesia : Data luminansi dan radiasi surya merupakan bagian yang sangat menentukan dalam proses perancangan bangunan.

Abstract:

Fabrication of PVDF films has been making using Hot Roll Press. Preparation of samples carried out for nine different temperatures. This condition is carried out to see the effect of temperature fabrication on electrical properties and crystallite size of PVDF films. The electrical properties like as surface resistivity are discussion focus in this paper. Surface resistivity properties of PVDF can be improved by mechanical treatment on the varying film thickness and the temperature. To obtain the diffraction pattern of sample characterization is performed using X-Ray Diffraction. Crystallite size of PVDF films calculate from broadening pattern of X-Ray Diffraction. Furthermore, from the diffraction pattern calculated β fraction and crystallite size, for calculation to determine the crystallite size of the sample by using the Scherrer equation. Has been obtained an increase piezoelectric properties of PVDF films that characterized by increasing β fraction. Have been obtained β fraction increased from 25.4% up to 44% for temperatures of 130°C up to 170°C, respectively. Resistivity value has been obtained at temperature 130°C up to 170°C, decreased from 1.23 × 104 Wm up to 0.21 × 104 Wm respectively. From the experimental results and the calculation of crystallite sizes obtained for the samples with temperature 130°C up to 170°C respectively are increased from 7.2 nm up to 20.54 nm. These results indicate that mechanical treatment caused increase β fraction and decrease surface resistivity. Increasing temperatures will also increase the size of the crystallite of the sample. This happens because with the increasing

Agama dalam Tentukur Antropologi Simbolik Clifford Geertz

International Journal of Islamic Thought , 2012,
Abstract: Clifford Geertz can be regarded as one of the most influential figures in religious studies, particularly in the field of anthropology. His unique symbolic anthropology approach had attracted researchers because of his emphasis on deductive reasoning in explaining the meaning of religion and in viewing cultural values that exist in religion. Research based on the content analysis of his works found that Clifford Geertz thought very strongly influenced by Ibn Khaldun as both of them emphasize on the practical reality of religious phenomena in the society. These symbols are then making a cultural system of what we call religion.
Fuzzy Jaccard with Degree of Optimism Ranking Index Based on Function Principle Approach
Nazirah Ramli,Daud Mohamad
Majlesi Journal of Electrical Engineering , 2010, DOI: 10.1234/mjee.v4i4.305
Abstract: Jaccard index similarity measure which applies the extension principle approach in obtaining the fuzzy maximum and fuzzy minimum has been proposed in ranking the fuzzy numbers. However, the extension principle used is only applicable to normal fuzzy numbers and, therefore, fails to rank the non-normal fuzzy numbers. Apart from that, the extension principle does not preserve the type of membership function of the fuzzy numbers and also involves laborious mathematical operations. In this paper, a simple vertex fuzzy arithmetic operation, namely function principle, is applied. This paper also proposes the degree of optimism concept in aggregating the fuzzy evidence. The method is capable to rank both normal and non-normal fuzzy numbers in a simpler manner with all types of decision makers’ perspective.
MANAGING CHRONIC DISEASES IN THE MALAYSIAN PRIMARY HEALTH CARE – A NEED FOR CHANGE
RAMLI AS,TAHER SW
Malaysian Family Physician , 2008,
Abstract: Chronic diseases are the major cause of death and disability in Malaysia, accounted for 71% of all deaths and 69% of the total burden of disease. The WHO in its report Preventing Chronic Disease: A Vital Investment has highlighted the inaction of most governments of the low and middle income countries in tackling the problem urgently, is clear and unacceptable. The acute care paradigm is no longer adequate for the changing pattern of diseases in today’s and tomorrow’s world. An evolution of primary health care system beyond the acute care model to embrace the concept of caring for long term health problems is imperative in the wake of the rising epidemic of chronic diseases and its crushing burden resulting in escalating healthcare costs. Compelling evidence from around the world showed that there are innovative and cost-effective community-based interventions to reduce the morbidity and mortality attributable to chronic diseases, but these are rarely translated into high quality population-wide chronic disease care. This paper describes the current situation of chronic disease management in the Malaysian primary care setting - to highlight the need for change, discuss the barriers to the implementation of effective chronic disease management programmes in the community, and consider fundamental solutions needed to instigate the change in our setting.

Media Peternakan , 2007,
Abstract: This research was conducted to study the effect of addition of Aceto-Sacch metabolite (m-AS) product into drinking water on performance, percentage of intestine and caeca of broilers. One hundred and fifty birds of day old chicks (DOC) of ‘Hubbard’ strain were divided into 5 groups of treatments. The treatments were R0 (control diet + drinking water without Aceto-Sacch metabolite / 0% m-AS), R1 (R0 + 12.5% m-AS), R2 (R0 + 25% m-AS), R3 (R0 + 50% m-AS), Rk (commercial diet + 0% m-AS). Chicken were given diet and drinking water ad libitum. Feed intake, body weight gain and feed conversion were measured weekly. Throughout four weeks feeding trial, two animals from each group were taken and decapitated for measuring percentage of intestine and caeca. Data from completely randomized design were analyzed statistically by analysis of variance (ANOVA) and contrast orthogonal. Results showed that drinking water containing more than 25% m-AS (R2 and R3) reduced body weight, feed intake and increased percentage of small intestine and caeca. However, m-AS addition at 12.5% improved feed conversion ratio and slightly increased body weight gain. Addition of 9.0 % m-AS in total drinking water was the optimum level increasing performance of broiler. It is concluded that addition of 12.5 % m-AS product into drinking water could slightly increased body weight gain and improve feed efficiency of broiler chicken.
Effect of Surfactant Concentration on the Physico-chemical Characteristics of Mesoporous Molecular Sieve
Sohail Ahmed,Anita Ramli
Journal of Applied Sciences , 2011,
Abstract: SEM), elemental analysis by using Energy Dispersive X-Ray (EDX), thermal stability by using Thermogravimetric Analysis (TGA), the functional groups within the samples before and after calcination was analyzed using Fourier Transform Infrared Spectroscopy (FTIR). Formation of the mesoporous material depends on the surfactant, which act as a structure directing agent. Micelles of the surfactant arrange themselves and interact with the silicate ions to form the mesoporous material. In this study, the effect of concentration was studied on the synthesis and found that due to increase in concentration of surfactant, more silica polymerized and formation of material increases.
