Universiti Pertahanan Nasional Malaysia or the National Defence University of Malaysia is a military university located in Sungai Besi Camp, Kuala Lumpur. The university is Malaysia's first catering to the needs and development of the Malaysian Armed Forces. There are around 2,700 undergraduate students, with over 1,300 of them Officer Cadets that undergoe four to six years of training. Wikipedia.

Twitter is one of the free micro bloggings available today. Created in 2006, Twitter has about 500 million registered users worldwide. Many scholars have been debating over the use of Twitter in teaching and learning. This brief research paper aims to look at Twitter as a source of revision for a course offered at the Defence University in Kuala Lumpur. The assumption is that the students are able to score a higher grade when Twitter is used as a revision tool. 32 students participated in this study and tweets were used to support students during their revision period before the second test. Data were analysed based on the results of Test 1 (without Twitter as a revision tool) and Test 2, where comparisons were made to see whether there is a change in the students' results. Further, the tweets sent to/shared with students and the retweets shared by students were also examined. A survey was also conducted to explore the respondents' thoughts on using Twitter as a revision tool. Preliminary findings suggest that the students had greatly benefitted when Twitter is used as a revision tool. This is because the results of Test 2 show that all students scored higher. The results of the survey also indicate that students were positive about using Twitter as a revision tool. Although it cannot be conclusively determined whether Twitter is the only factor that contributes to the increase of students' results in Test 2, this paper will highlight how Twitter can be used as an effective revision tool.

Military section will communicate verbally or visually in the battlefield. Before engaging the enemy, section leader will give commands visually as not to alert the enemy. Once the enemy is engaged, all commands will be verbal. Shooting might cause for some of these commands to be lost due to the noise and confusion. In addition to that, upon engagement by the enemy, soldiers will try to go behind cover to avoid getting shot at. Hiding behind cover will cause the soldier to loose situational awareness. The section leaders might also not be able to give commands effectively to the soldiers. The Small Unit Tactical Silent Communication System (SUTACSICS), a module to be integrated into the Malaysian Army Small Unit Tactical Management System (SUTaMS), was developed using Network Centric Technologies to ensure that section leaders in the battlefield are able to communicate with their soldiers silently and effectively without using either the visual or verbal method of communication. Commands to be sent are selected from a preset list and vibration to alert the soldiers on arrival of the command. © 2011 Springer-Verlag.

The protective properties of the blood-brain barrier (BBB) are conferred by the intricate architecture of its endothelium coupled with multiple specific transport systems expressed on the surface of endothelial cells (ECs) in the brain's vasculature. When the stringent control of the BBB is disrupted, such as following EC damage, substances that are safe for peripheral tissues but toxic to neurons have easier access to the central nervous system (CNS). As a consequence, CNS disorders, including degenerative diseases, can occur independently of an individual's age. Although the BBB is crucial in regulating the biochemical environment that is essential for maintaining neuronal integrity, it limits drug delivery to the CNS. This makes it difficult to deliver beneficial drugs across the BBB while preventing the passage of potential neurotoxins. Available options include transport of drugs across the ECs through traversing occludins and claudins in the tight junctions or by attaching drugs to one of the existing transport systems. Either way, access must specifically allow only the passage of a particular drug. In general, the BBB allows small molecules to enter the CNS; however, most drugs with the potential to treat neurological disorders other than infections have large structures. Several mechanisms, such as modifications of the built-in pumping-out system of drugs and utilization of nanocarriers and liposomes, are among the drug-delivery systems that have been tested; however, each has its limitations and constraints. This review comprehensively discusses the functional morphology of the BBB and the challenges that must be overcome by drug-delivery systems and elaborates on the potential targets, mechanisms, and formulations to improve drug delivery to the CNS. © 2014 Alyautdin et al.

Introduction: Elevated intraocular pressure (IOP) in glaucomatous eyes is often due to increased resistance to aqueous outflow. Previous studies have shown that increased extracellular material deposition in outflow pathways leads to increased resistance to aqueous outflow, and transforming growth factor (TGF)-β seems to play a role in the deposition of extracellular material. TGF-β2 is the predominant isoform in ocular tissue. Hence, comparison of the aqueous humor TGF-β2 level between patients with open-angle glaucoma (OAG) and controls would provide direct evidence for the role of TGF-β2 in the etiology of OAG. Hence, we performed this meta-analysis to develop an accurate estimate of the changes in aqueous humor TGF-β2 levels among OAG patients. Methods: We undertook the meta-analysis of data from all available studies that had a case-control design and investigated the aqueous humor levels of TGF-β2 (total, active, or both) in OAG patients. OAG included primary OAG (POAG), secondary glaucoma, pseudoexfoliation syndrome, and exfoliation glaucoma (EXG). Results: We selected a total of eight studies that measured TGF-β2 levels in the aqueous humor of glaucomatous eyes. The studies included in this meta-analysis clearly demonstrated that in OAG eyes, total TGF-β2 levels are significantly elevated, whereas in POAG eyes, both the total and active TGF-β2 levels are significantly higher than in controls. Conclusions: The analysis of pooled data showed that aqueous humor TGF-β2 levels are elevated in patients with OAG and POAG. © 2015 Molecular Vision

The selection of flow passage's cross section shape is important in thermal system design such as compact heat exchanger. A variety of duct's shapes can be used to enhance the thermal performance. However, it must be noted that different thermal and friction characteristics can be initiated due to this approach. Therefore this paper investigates the entropy generation characteristics of three types of duct's cross section subjected to constant heat flux. The considered shapes are circular, square and triangle (equilateral). Al2O3 and MWCNT based nanofluids are used as working fluids in the analysis. The study found that the total entropy generation of Al2O3 based nanofluids decreases with the increase of particle volume fractions. However, this parameter increases when working fluid's mass flow rate and heat flux applied to the duct increase. On the aspect of cross section's shape, circular duct exhibits lowest total entropy generation compared to other considered shapes. Moreover, it was also found that MWCNT based water nanofluids exhibit lower total entropy generation compared to Al2O3 based nanofluids due to its high thermal conductivity value. © 2014 Elsevier Ltd.
