Wind energy has often been touted as one of the most reliable sources of renewable energy that should be used for people. Today, wind energy (mainly by propeller type wind turbines) produces less than one percent of the total energy used worldwide. Practically, a standard three-blade propellers efficiency of use of the wind energy is around twenty percents and this is due to its design and shape that use the wind lift force and a rotating turbine. In addition, these turbines are quite expensive due to the complex aerodynamic shape of the propellers which are made of composite materials. The new world boom for wind turbines obliges inventors to create new wind turbine designs that have high efficiency and are better than any known design. This paper proposes the new patented invention of the vane-type wind turbine which uses wind energy more efficiently and is only dependent on the acting area of the vanes. The vane wind turbine was designed to increase the output of a wind turbine that uses kinetic energy of the wind. Due to its high efficiency, simple construction and technology, the vane wind turbine can be used universally, apart from the fact that it is made from cheap materials. The new design of the vane-type wind turbine has quite small sizes than the propeller type one of same output power.

In this paper, an extensive work on the natural frequency of perforated plate has
been made by introducing micro-holes on the plate. The micro-holes, which is known
to have a remarkable performance in several applications, were arranged diagonally
among the perforated holes in order to make a new combination of micro-macro
perforated plate. A 3D geometrical model of the plate was made in the Autodesk
Inventor and the Finite Element (FE) simulation was employed to calculate the
natural frequency and visualize the mode shape. Four models were made with
various micro-holes diameter starting from 0,25, 0,5, 0,75 and 0,9 mm, respectively.
The macro holes diameter, however, was kept constant to be 1,5 mm purposely to
know the effect of micro holes in particular. The results from the models were then
compared to a single perforated plate (PP) for clarification. It is found that the micro
holes gives considerable effect to the perforated plate natural frequency. Similar to
the author previous findings, the diameter of the micro holes is proportional to the
natural frequency reduction.

Fulltext Assessing Prevalence and Unique Risk Factors of Suicidal Ideation among First-Year University Students in China Using a Unique Multidimensional University Personality Inventor

Wu O, Lu X, Yeo KJ, Xiao Y, Yip P

Int J Environ Res Public Health, 2022 Aug 30;19(17).
PMID: 36078501 DOI: 10.3390/ijerph191710786

BACKGROUND: University students with suicidal ideation are at high risk of suicide, which constitutes a significant social and public health problem in China. However, little is known about the prevalence and associated risk factors of suicidal ideation among first-year university students in China, especially during the COVID-19 pandemic.
OBJECTIVES: To investigate the prevalence of suicidal ideation and its factors in first-year Chinese university students from a vocational college in Zhejiang during the COVID-19 pandemic.
METHODS: Using a cluster sampling technique, a university-wide survey was conducted of 686 first-year university students from Hangzhou in March 2020 using University Personality Inventory (UPI). UPI includes an assessment for suicidal ideation and possible risk factors. Suicidal ideation prevalence was calculated for males and females. Univariate analysis and multivariable logistic regression models were conducted, adjusting for age and sex. Analyses were carried out using the SPSS version 22.0 software.
RESULTS: The prevalence of 12-month suicidal ideation among first-year university students during March 2020 was 5.2%, and there was no significant difference between males and females (4.8% vs. 6.0%, x2 = 0.28, p = 0.597). Multivariable logistic regression analysis identified social avoidance (B = 0.78, OR = 2.17, p < 0.001) and emotional vulnerability (B = 0.71, OR = 2.02, p < 0.001) as positively associated with suicidal ideation.
CONCLUSIONS: Social avoidance and emotional vulnerabilities are unique factors associated with greater suicidal ideation among first-year university students during the COVID-19 pandemic. UPI serves as a validated tool to screen suicide risks among Chinese university students. Encouraging social engagement and improving emotional regulation skills are promising targets to reduce suicidal ideation among first-year university students.

Blindness is an area of inadequate the visual conception because of physiological or even neurological aspects. The partial blindness corresponds to the insufficient integration in the expansion of the optic confidence or perhaps visual center of the eye, and also over-all total blindness is the complete inadequacy of the visual light perception. Within this research, a basic, inexpensive, friendly user, sensible blind assist technique is developed to be integrated with the portability of both blind and even visually impaired people in a particular region. The presented work consists of a wearable apparatus is made up of the head hat to facilitate the blind particular person to get around single-handedly safely and securely in order to keep away from any kind of obstructions that could be experienced, even if mounted and also mobile phone, to avoid virtually any probable accident. The primary function of this product is the Ultrasonic sensing unit which is able to inform the blind people if there exist any specific obstacles or otherwise not around them along with the vibrating motor probably would informs the blind people who which negative are the obstacles located. In addition, by pressing the home or work button this system will straight away link to MIT app inventor and the app will send a signal to Google maps to guide the blind people to its desired location. The implemented system is fast, and easy to use and an innovative affordable solution to blind and visually impaired people in third world countries.

In Malaysia, the number of Musculoskeletal Disorder (MSD) cases is increasing . Rapid Upper Limb Assessment
(RULA) is carried out in a physical paper form which is cumbersome and based on the complex nature and it should
consider human error. This project aims to create the RULA application for mobile devices featuring the android system
for this move will cut down the process time by more than half, create a more structured system and eliminate human
error wholly. The application will be designed on the App Inventor website which features a lot of handy tutorials
and takes the initiative to create a RULA mobile app for Android phones. The RULA mobile app for Android phones
is intended to make it easier and much more efficient to conduct a RULA analysis. Additionally, the analyses can be
conducted by minimally trained users, eliminating the need for highly trained technicians. RULA test is performed to
achieve accurate results and the mathematical processes will be programmed into the app so that the user will have a
friendly interface and will only be asked to tick boxes.

In Malaysia, all sectors are currently gearing themselves in supporting the initiatives of becoming a developed nation by the year 2020. The most important element in ensuring the success of this mission is to provide critical mass of knowledge workers to champion this cause. As such the Ministry of Higher Education Malaysia (MOHE) has established the National Higher Education Strategic Plan (NHESP), comprising seven thrusts which are very crucial in providing the much needed human capital and eco-system for this agenda. The essence of NHESP is also in line with other initiatives established by the government of Malaysia such as the National Key Results Area (NKRA) and the Government Transformation Plan (GTP). In fact MOHE has developed a systematic working model for the academia to play their role actively in driving the agenda of transforming Malaysia into a developed nation. The workforce required to spearhead the agenda for an innovation-led economy can be categorized into five different groups namely: Discoverers; Innovators; Inventors; Transformers; and Technopreneurs. It is very crucial for MOHE to develop and implement a comprehensive programme for producing a new breed of researchers that can contribute in translating government policies into a reality. This article presents the challenges and success stories in reforming the landscape of Research and Development in Malaysian universities and research institutions. The establishment of NHESP has made it possible for MOHE to systematically establish comprehensive guidelines for the management of research grants, standard for research conduct, instrument to measure research performance, and standardized reporting of research and innovation output. This new approach in the management of research at the ministry level has created positive ramifications for universities, research institutions, research management centres, and research leaders. During the first five-year cycle (2006-2010) of these research initiatives, and now into the second phase (2011-2015), positive results and outcomes have started to emerge. These results include increased in generation of articles on research findings published in reputable journals worldwide. Currently, Malaysia is recognized for achieving the world's fastest growth rate in number of journal publications. In addition, increased in number of postgraduate students, commercialization of R&D products and the establishment of Higher Institutions Centres of Excellence (HiCOE) contribute towards producing a new breed of great researchers in Malaysia. A continuing positive trend indicates that this phenomenal growth will be sustained for the next few years.
