Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.3474.3480
Abstract: Seroepidemiological survey of Caseous Lymphadenitis (CLA), a bacterial infection in sheep and goats was conducted in East Coast Economic Regions (ECER) in peninsular Malaysia. A total of 422 animals (n = 422) from 15 small ruminant farms (sheep and goats) in the four states were screened during the period from January to April 2011. The management practices that could be associated with CLA occurrence was also analyzed. The objective of this survey was to determine the overall status of CLA infections in small ruminants. AGPT was conducted on serum samples collected from animals. About 47 samples out of 422 yielded a positive reaction for AGPT test. The frequency of CLA infections was estimated at 11.1%. Management practices were analyzed through questionnaire. All farmers (15/15) had semi-extensive rearing system; 27.6% (13/47) of farmers had periodical veterinary services; 10.6% (5/47) took note of animals with clinical signs of CLA; 14.8% (7/47) were aware of the zoonotic potential of this disease. Lack of sanitary measures and epidemiological studies led the dissemination of this disease in Malaysia. Moreover, the economic importance of this disease seems to be overlooked by both individual and state level allowing existence of endemic nature of the disease in this country. Therefore, further epidemiological studies using reliable diagnostic tools and application of appropriate management practices need to be implemented for aiding control and eradication programs for this disease.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.4660.4667
Abstract: Corynebacterium pseudotuberculosis is the etiological agent of caseous lymphadenitis, a chronic infectious disease of sheep and goats. Despite the growing interest of this organism, little is known about the causality and effect of this organism on haematological and biochemical values. The purpose of this research, therefore was to determine haematological and serum biochemical features in mice inoculated with whole bacterium and exotoxin (PLD) extracted from C. pseudotuberculosis. The study was performed on apparently healthy mice of 2-3 weeks old (n = 64). The mice were divided equally into 3 groups; namely whole bacterium, exotoxin (PLD) and control group. Mice of whole bacterium group were exposed intraperitoneally to 1 mL of the inoculums containing 109 Colony-Forming Unit (CFU)/mL of live C. pseudotuberculosis. Exotoxin group were exposed intraperitoneally with a single dose of exotoxin (PLD) extracted from C. pseudotuberculosis. Mice served as a control group were challenged intraperitoneally to 1 mL of Phosphate-Buffered Saline (PBS), pH 7. Following post-infection, the mice were subjected for blood sample collection using cardiac puncture method for haematological and biochemical analysis. The results of this study revealed that there were significant decrease (p<0.05) in Hb, thrombocytes count and significant increase in WBC, neutrophils, monocytes counts in the infected group. Biochemically, there were highly significant increase (p<0.05) in the mean levels of CK, AST, ALP and ALT. The mean level of albumin in exotoxin group was significantly lower (p<0.05) compared to C. pseudotuberculosis and control groups while globulin level was significantly higher in C. pseuodotuberculosis group after 48 h. In serum electrolytes, mean level of potassium and phosphate were significantly (p<0.05) higher in infected groups compared to control group while there was no significant (p<0.05) difference in the levels of sodium, calcium and chloride. In conclusions, the present study of experimental nature showed that C. pseudotuberculosis and its exotoxin (PLD) cause disturbances in blood factors and electrolytes and pointed out that t hese haematological and biochemical alterations should be taken into account in the context of diagnosis and treatment of valuable infected hosts in order to prevent further consequences.

Abstract: The existing flanges component which is produced by traditional sand casting shows low quality both of the material and dimension, since the product made from recycled material and supported by a very simple technology. The quality of casting is not depends on the microstructure, but also supported by a good appearance. This research is to analyze the effect of process parameters by producing specimens through squeeze casting process using the existing recycled material. Process parameter such as squeeze pressure and punch & die temperature. The process consists of melting the alloys and heating the die in two difference resistance furnaces, ladling the melt into pre-heated die cavity and finally applying pressure by hydraulic power until the melt is fully solidified. After investigating the specimen, the results show that the quantity of the porosity as compared to traditional sand casting is decreasing significantly.

Abstract: Sexual and reproductive health problems among adolescents are increasing in trend. Inadequate knowledge of sexual and reproductive health is the main cause of problems in sexual and reproductive health. Short messages service (SMS) intervention has been implemented widely in health education and the outcomes are positive. Hence, this study was conducted to evaluate the effects of mobile phone messaging in improving sexual and reproductive health among late adolescents (age 18 - 19 years old). A quasi-experimental study was conducted in two Professional Vocasional Colleges in Malaysia. A total of 116 respondents in the intervention group and 130 respondents in the control group had completed the study. There was a series of 24 messages (SMS) sent to the respondents biweekly for 12 weeks. The adolescent girls (mean knowledge score 15.90, sd ± 3.321) in the intervention group had a significantly (P = 0.007) higher mean score in knowledge of sexual and reproductive health than boys (mean knowledge score 13.87, sd ± 4.003) at post intervention. The adolescent boys (mean knowledge scores 15.35, sd ± 4.748) in the control group had a significantly (P = 0.009) higher mean score for knowledge on HIV/AIDS than girls (mean scores 13.08, sd ± 4.325) at post intervention. In the intervention group, the number of respondents with good knowledge and good attitude on HIV/AIDS increased at 3 months post intervention. SMS intervention on knowledge of sexual and reproductive health for adolescents was accepted and effectively improved the knowledge scores and sustained even after 3 months post intervention. Therefore, the SMS intervention should be implemented as an intervention package to improve knowledge and reduce risk in developing sexual and health related problems among adolescents.

Jurnal Teknik Mesin , 2000,
Abstract: Squeeze casting, also known as liquid metal forging, is a term commonly used to describe a process by which molten metal solidifies under pressure within closed dies position between the plates of a hydraulic press. The applied pressure and instant contact of the molten metal with the die surface produce a rapid heat transfer condition that yields a pore-free fine grain casting with mechanical properties. Which is similar to those of wrought products. This papers reviews aspect of recent progress in the development of current squeeze casting techniques, and address both the advantages and limitations of the various processes. Abstract in Bahasa Indonesia : Pengecoran squeeze, yang juga dikenal dengan istilah penempaan logam cair, merupakan suatu istilah yang dipakai untuk menggambarkan suatu proses dimana logam cair didinginkan di dalam cetakan tertutup sambil diberi tekanan luar yang biasanya berasal dari tenaga hidrolik. Tekanan yang diberikan serta kontak langsung antara logam cair dengan dinding cetakan akan menyebabkan terjadi perpindahan panas secara cepat yang memungkinkan untuk menghasilkan produk cor dengan porositas rendah serta memiliki ukuran butir yang halus dengan sifat mekanik yang mendekati produk tempa umumnya. Karya tulis ini mencoba mengkaji perkembangan terkini dari pengecoran squeeze serta keunggulan dan keterbatasan proses ini dibandingkan proses-proses lainnya. Kata kunci: pengecoran squeeze langsung, pengecoran squeeze tak langsung

Abstract: Transrectal ultrasonography (TRUS) of cases with pathologically proven chronic prostatitis will be presented. There is confusion about the cause of chronic prostatitis. There is also a dilemma about the diagnosis. Sonography (TRUS) is the best modality for it. I have carried out research on patients who had TRUS and biopsy. In these cases, the pathology proved that they had contracted chronic prostatitis. I studied the sonographies and the features which will be discussed and presented."nThe second lecture is "the incidence of cancer of prostate in abnormal PSA"."nI have performed approximately 5000 prostate biopsies on 500 patients and the results will be discussed. In addition, I will mention when biopsy is indicated, age related PSA and the value of free PSA.
