Physical activity level among undergraduate students in Terengganu, Malaysia using pedometer

A cross-sectional study determine physical activity level among 95 undergraduate students at UniSZA using pedometer. Subjects consented and completed socio-demographic details, weight and height were measured. Each subject was supplied with a pedometer and wear it for a week and record steps per day from the pedometer each night before bed. Descriptive statistic and independent T-test coefficient analyze the data using IBM SPSS version 22.0. Results showed that 66.4% of the subjects were classified as sedentary according to pedometer determined physical activity. Males recorded significantly more steps than female per day. Subjects in the age group of 18-20 years old had the highest mean average steps count than the older age group of 21-24 years old and ≥ 25 years old per day. Only 5.2% were classified as active and highly active using pedometer determined physical activity level.Keywords: physical activity; pedometer; steps; body compositio

Review of Multilevel Inverter Topologies and Its Applications

Nowadays, multilevel inverter technologies have attracted attention as a convenient solution in many industrial applications. There are a few interesting features of using this configuration, where less component count, less switching losses, and improved output voltage/current waveform. The most significant criteria in multilevel inverter is the minimization of harmonic components in the inverter output voltage/current. The evolution of multilevel inverter technologies and the commercial products based on a multilevel inverter topology has shown tremendous developments due to the many advantages. In this paper, a review of the classical multilevel inverters and the recently introduced topologies are presented. They are trending as the most preferable power electronics device that have been widely used in the applications like motor-drive applications up to MegaWatt (MW) power levels, renewable energy (solar/wind power inverters) and reactive power compensation (i.e. STATCOM). This paper provides a general comparisons for various type of multilevel inverters and their suitable applications with useful references

Study on the Coral Reefs of Pulau Pinang, Terengganu and Pulau Satang, Sarawak

Assessments of the percentage coral cover caried out at Pulau Pinang and Pulau Satang using the line transect technique showed the reefs status are generally mediocre. A total of 5 stations were surveyed on both islands and 3 stations in Pulau Pinang are mediocre (41 - 45% cover) while one is in good condition (68%). Pulau Satang recorded a percentage coral cover of 41% which is also mediocre. Two main factors contributing to the deterioration of reefs in Pulau Pinang are Acanthaster plancii predation and uncontrolled diving and snorkeling activities. Sedimentation, temperature and salinity are factors contributing to the deterioration of ree£ in Pulau Satang. Eighteen species of corals were identified at both locales; the most dominant species for Pulau Pinang are Acropora halmahelO , A. nobilis and Montipora sp. while Astreopora sp., Favtafavus and Acropora palifera were dominant at Pulau Satang. There is a significant difference of percentage cover between Pulau Pinang and Pulau Satang. In Pulau Satang, TSS ranges from 0.01-0.05 g/L, nitrate ranges from 0-0.02 mg/L, nitrite ranges from 0.02-0 .04 mglL, phosphate ranges from 0.33-1.13 mg/L, pH ranges from 8.0- 10.3 and temperature ranges from 30.0-30.8°C

Artocarpus altilis compound based study for anti-cancer proliferation on Hela cell via electroporation method

Survivors of cancer often have multiple permanent side effects due to the usage of drugs during the therapy. This study combining the compound artocarpus altilis and the optimized electroporation method for maximum HeLa cancer cell anti-proliferation activity. Artocarpus altilis or also known as sukun, is a natural compound, which has the capability to treat cancer as it has anti-proliferation effect in cancerous cells. Hence, in this current work, voltage amplitude of 200V/cm, 400V/cm, 600V/cm, 800V/cm, 100V/cm with 30μs of pulse duration used in electroporating HeLa cancer cell to look at the effects on cell’s extension, cell size and growth rate. However, this study requires further investigation to identify the optimal electroporation conditions that can be applied to effectively deliver the artocarpus altilis extracts to the HeLa cancer cells in order to inhibit its proliferation.Keywords: electroporation; irreversible electroporation; artocarpus altilis
