Simple Estimation Air Temperature From Modis Lst in Gifu City, Japan

In the developing country or poor country difficult to access meteorological data such as air temperature, it\u27s caused by the limitation of equipment or funding. Air temperature is one of the meteorological data commonly used to predict evaporation or to understanding climatic condition in a specific location. Nowadays from satellite data can estimate some meteorological data. But the detail of explanations about how to get and how to use satellite data is limited and difficult to adopt for beginners. This paper explains how to get MODIS LST data to estimate air temperature data study case in Gifu City, Japan. The results show data from MODIS LST is higher than data from the local meteorological station for day time and lower for night time, but still can use because the pattern is similar. Mean of maximum air temperature and minimum air temperature can be used as daily average air temperature. MOD11A2 product data was better than MYD11A2 data to predict air temperature. MODIS LST data can be used for untouched areas like desert or forest

Detection of aerolysin and hemolysin genes in Aeromonas spp. isolated from environmental and shellfish sources by polymerase chain reaction

Polymerase chain reaction (PCR) technique was used to assay for the detection of specific genes in the genomes of the Aeromonas spp. isolated from environmental and shellfish sources, particularly aero and hlyA genes, responsible for aerolysin and hemolysin toxins production in this genus. The results showed that: (i) the 1500 bp amplicon of the hlyA gene was detected in 20/38 of the Aeromonas hydrophila, 13/38 of the A. caviae and 6/9 of the A. veronii biovar sobria isolates; (ii) the 690 bp amplicon of the aero gene was detected in 20/38 of A. hydrophila, 17/38 of A. caviae and 6/9 of A. veronii biovar sobria isolates; (iii) the nucleotide blast results of aerolysin gene sequences of the representative strains of A. hydrophila, A. caviae and A. veronii biovar sobria revealed a high homology of 94%, 95% and 95% with published sequences, respectively and; (iv) the protein blast showed 97%, 94% and 96% homology when compared to the published sequences, respectively. The finding of A. hydrophila virulence genes in other members of the genus Aeromonas, may give a new perspective to the significance of these results. The method described here may be a useful detection tool to assist in further investigation of aero and hlyA genes in the genus Aeromonas, especially for food microbiologist

Development of the Malay digit triplet test via headphones and telephones as a national hearing screening tool in Malaysia

Introduction: This study aimed to develop a self-administered hearing screening test using digit triplets in Malay (MDTT) to be used as a national hearing screening tool via internet and telephone landlines in Malaysia. Methods: Recordings of disyllabic Malay digits by a female Malay native speaker were used together with a speech shaped stationary noise (TSN). The test stimuli were normalized using responses from twenty normal hearing native Malay speakers. The data were used to produce eight equivalent test lists. An additional twenty normal hearing native Malay speakers were recruited to test the lists equivalency. Forty six listeners with varying levels of hearing were recruited to validate the tests. ROC analysis was done to identify the pass and refer cut-off limits. Results: No statistical differences were found between lists for both test conditions. The evaluation in fixed SNRs resulted in a mean speech reception threshold (SRT) of -11.3 ± 0.34 dB SNR for headphone and -10.24 ± 0.1 dB SNR for telephone applications. A significant main effect of type of transducer was observed in both normal and hearing impaired groups. The cut off for refer, sensitivity and specificity for the tests using telephones are (-5.8dB, 80.8%, 95%) and headphones (-9.8dB, 80.8%, 100%). Conclusions: The MDTT was successfully developed and the normative values are comparable to other versions of the digit triplet tests. The MDTT showed high sensitivity and specificity and can be made available to any Malay speaking public via telephone and internet

Optimization of the force characteristic of rotary motion type of electromagnetic actuator based on finite element analysis

The needs for non-invasive technique in breast cancer detection could enhance and preserve the future of medical field in Malaysia as well as countries around the world. Breast cancer has become the main concern nowadays not only for women but for man as well. In overall, the risk of women getting breast cancer is higher than man due to the denser tissue of breast in women compare to man. Beside the unawareness for the disease, the reason which contributes to this increasing number of breast cancer reported is also due to the limitations arising from modalities such as MRI, Mammography, ultrasound and other modalities. An alternative to current technologies should be improved for early detection and treatment which causes no physical harm to patients if possible. Thus, non-invasive and better technology in detecting breast cancer is very much needed in the current market. This paper will be discussing the insights of Magnetic Induction Tomography techniques in breast cancer detection

Informasi mengenai persebaran dan struktur komunitas sumber daya ikan demersal penting sebagai bahan masukan untuk pengelolaan perikanan demersal. Penelitian ini bertujuan untuk menganalisis tingkat keanekaragaman dan persebaran sumber daya ikan demersal berdasarkan perbedaan kedalaman perairan, serta keterkaitannya dengan lingkungan. Penelitian dilaksanakan di Laut Cina Selatan pada bulan Mei sampai Juni 2015 dengan mengoperasikan alat tangkap pukat ikan di stasiun yang telah ditetapkan. Metode analisis keanekaragaman hayati ikan demersal menggunakan beberapa indeks ekologi yaitu indeks kekayaan jenis Margalef, indeks keanekaragaman Shannon-Wiener, indeks keseragaman Pielou, dan indeks dominansi Simpson. Nilai indeks ekologi tersebut kemudian dikaitkan dengan kondisi lingkungan, menggunakan analisis komponen utama. Hasil penelitian menunjukkan tingkat kestabilan komunitas sumber daya ikan demersal semakin baik seiring dengan meningkatnya kedalaman. Kedalaman, suhu, dan salinitas merupakan parameter yang paling memengaruhi tingkat kekayaan jenis serta persebaran sumber daya ikan demersal, sedangkan persebaran kelimpahan ikan sangat terkait dengan oksigen terlarut dan kecerahan perairan. Implikasinya, kondisi lingkungan perairan sangat memengaruhi persebaran dan kelimpahan ikan demersal

Note: characterization of Vibrio cholerae O139 Bengal isolated from water in Malaysia

Four Vibrio cholerae O139 Bengal strains isolated from surface water were characterized by antibiotic resistance, plasmid profile, presence of cholera toxin gene and random amplification of polymorphic DNA (RAPD) analysis. All four strains exhibit multiple resistance towards the antibiotics tested with a multiple antibiotic resistance index of 0·5–0·66, and harboured a 2·0 MDa non-conjugative plasmid. The Vibrio cholerae O139 Bengal were positive for the cholera toxin gene. Antibiotyping and random amplification of polymorphic DNA analysis with four primers proved to be useful in discriminating the isolates. RAPD proved to be more sensitive. These results reveal that there is significant genetic diversity among the Vibrio cholerae O139 Bengal strains studied
