Introduction: Hepatic radioembolization is a minimally invasive procedure involving intrarterial administration of radioembolic microspheres for the treatment of liver tumours. In this study, a biocompatible polystyrene (PS) microspheres formulation containing radioactive Samarium-153 (153Sm) was synthesized and tested. The 153Sm emits both diagnostic gamma energy and therapeutic beta radiation, renders the synthesized microspheres an ideal theranostic radioembolic agent for hepatic radioembolization. Methods: First, the 152Sm2O3 (20 – 50%, w/v) was encapsulated in PS microspheres using solid-in-oil-in-water solvent evaporation method. The 152Sm-labelled PS microspheres were then activated to 153Sm (Eβmax = 807.6 keV, half-life = 46.3 hours) via 152Sm (n,γ) 153Sm reaction in a nuclear reactor with a neutron flux of 2.0 x 1012 n.cm-2.s-1. Physicochemical characterization, gamma spectroscopy and in-vitro radiolabeling studies were carried out to study the properties and stability of the microspheres before and after neutron activation. Results: The 153Sm -labelled PS microspheres achieved a nominal activity of 4.0 GBq.g-1 after 6 hours of neutron activation. Scanning electron microscope (SEM) and particle size analysis show that the microspheres remained spherical with diameters within 15 – 60 μm after neutron activation. No long half-life radioimpurities were found in the samples as revealed by the gamma spectroscopy results. The 153Sm-labelled PS microspheres achieved radiolabeling efficiency of more than 95% in saline and blood plasma over 480 hours. Conclusion: A biocompatible 153Sm-radiolabelled PS microspheres formulation has been successfully developed. The formulation achieved desirable properties for theranostic treatment of liver tumours. The formulation is relatively cheaper, easier to be produced and more readily available.

BACKGROUND: Streptococcosis and Motile Aeromonad Septicemia (MAS) are important diseases of tilapia, Oreochromis spp. and causes huge economic losses in aquaculture globally. The feed-based vaccination may be an alternative to minimize major infectious diseases in tilapia. Thus, this study aims to evaluate the haemato-immunological responses and effectiveness of a newly developed feed-based killed bivalent vaccine against Streptococcus iniae and Aeromonas hydrophila in hybrid red tilapia. A total of 495 hybrid red tilapia of 61.23 ± 4.95 g were distributed into 5 groups (each with triplicate). The fish were immunized orally through bivalent (combined S. iniae and A. hydrophila) spray vaccine (BS group), bivalent formulate vaccine (BF group), monovalent S. iniae vaccine (MS group), monovalent A. hydrophila vaccine (MA group) and unvaccinated as a control group. The vaccine was orally administered on days 0, 14 and 42 applied feed-based bacterin at 5% body weight. The blood and spleen samples were collected from all groups on 7, 21 and 49 days post-vaccination, and also 96 h post-infection to assess their haemato-immune responses.
RESULTS: Compared with the unvaccinated group, leukocyte, lymphocytes, monocytes, granulocytes counts in vaccinated groups were significantly (P

Boron has been classified as a drinking water pollutant in many countries. It is harmful to many plants, exceptionally sensible plants, and human health. Therefore, boron level needs to be decreased to 0.3 mg/L for drinking water and within 0.5 mg/L to 1 mg/L for irrigation water. In this study, various operational parameters namely pH, contact time and liquid/solid ratio were investigated to determine the potential of using date seed (or date pit or date stone) to remove boron from seawater. This study's main objective was to determine boron adsorption capacities of date seeds prepared by various methods (i.e., powdered, activated, acid-treated and defatted seed) by batch adsorption process using boron contaminated synthetic seawater. The process parameters of the selected biosorbent among the four date seed preparations methods were optimized. The surface characteristics were analyzed by using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM). The results showed that acid-treated date seed was the best biosorbent in terms of removing 89.18% boron from aqueous solution at neutral pH, liquid to solid ratio of 5 within 2 hours of reaction time at room temperature (25°C±2°C).

Radio frequency (RF) magnetron sputtering was used to deposit tungsten disulfide (WS2) thin films on top of soda lime glass substrates. The deposition power of RF magnetron sputtering varied at 50, 100, 150, 200, and 250 W to investigate the impact on film characteristics and determine the optimized conditions for suitable application in thin-film solar cells. Morphological, structural, and opto-electronic properties of as-grown films were investigated and analyzed for different deposition powers. All the WS2 films exhibited granular morphology and consisted of a rhombohedral phase with a strong preferential orientation toward the (101) crystal plane. Polycrystalline ultra-thin WS2 films with bandgap of 2.2 eV, carrier concentration of 1.01 × 1019 cm-3, and resistivity of 0.135 Ω-cm were successfully achieved at RF deposition power of 200 W. The optimized WS2 thin film was successfully incorporated as a window layer for the first time in CdTe/WS2 solar cell. Initial investigations revealed that the newly incorporated WS2 window layer in CdTe solar cell demonstrated photovoltaic conversion efficiency of 1.2% with Voc of 379 mV, Jsc of 11.5 mA/cm2, and FF of 27.1%. This study paves the way for WS2 thin film as a potential window layer to be used in thin-film solar cells.

Mesoporous carbon is a promising material having multiple applications. It can act as a catalytic support and can be used in energy storage devices. Moreover, mesoporous carbon controls body's oral drug delivery system and adsorb poisonous metal from water and various other molecules from an aqueous solution. The accuracy and improved activity of the carbon materials depend on some parameters. The recent breakthrough in the synthesis of mesoporous carbon, with high surface area, large pore-volume, and good thermostability, improves its activity manifold in performing functions. Considering the promising application of mesoporous carbon, it should be broadly illustrated in the literature. This review summarizes the potential application of mesoporous carbon in many scientific disciplines. Moreover, the outlook for further improvement of mesoporous carbon has been demonstrated in detail. Hopefully, it would act as a reference guidebook for researchers about the putative application of mesoporous carbon in multidimensional fields.

Introduction: Recent Coronavirus outbreak has raised concern among student nurses who are doing their clinical posting tenure regarding the risk ofpatient acquired infection. This study examined perceived readiness to pro- vide coronavirus patient careduring clinical posting among student nurses in UMS. Method: This study deployed a cross-section survey design using a self-rated questionnaire to evaluate respondents’ level of readiness towards Coronavirus patient care. A total of 177 (N) respondents comprising of nursing students from UMS (year 1 n=55, year 2 n=56, year 3 n=66) participated in the study. The study questionnaire captured demographics and comprised of 15Likert -scale items that assessed the level of perceived readiness to provide Coronavirus patient care. The ques- tionnaire was adapted from a previous SARs pandemic studyand revalidated within the local context (α = 0.78). Data analysis used descriptive statistics by frequency counts and Fisher exact test for demographic correlates with the level of readiness. Results: Among 177 student nurses in this study68% (n= 121) were willing and ready to provide Coronavirus patient care and 32% (n = 56) were hesitant or not willing. Regarding confidence of safety using PPE to provide patient care, 34 % (n = 61) of respondents rated not confident and deemed it hazardous even with full PPE use. On the issue of if legally mandated to care for Coronavirus patients, 22% were hesitant to provide care and will considerleaving nursing training if compelled to do so. There was a significantly lower perceived level of readiness towards Coronavirus patient care among 1st-year student nurses and those who had not attended any Coronavirus educational session (p= 0.06). Conclusion: The findings indicate although the majority of student nurses are willing to provide care for Coronavirus infected patients during their clinical posting tenure, a small proportion of student’s nurses were hesitant.

The informal sector is a major part of the Malaysian economy, and there is still insufficient information about the informal economic activities in Malaysia. In the term, 'informal economy' became current as a label for economic activities which take place outside the framework of corporate public and private sector establishments. According to International Labor Organization (ILO), the common characteristics of the informal enterprise includes the ease of entry, reliance on an indigenous resource, family ownership, small scale operations, labour-intensive and adaptive technology, skills acquired outside of the formal sector, unregulated and competitive markets. The objective of this paper is to identify the participation of informal sector among women in Malaysia. How much females participate in the informal sector and why they participate. This paper also discusses the challenges and opportunities of women participating in the informal sector in Malaysia to explain why females participate in the informal sector and the policy implications of their participation. The study found that the major challenges of women involved in informal activities which are financial difficulties, social security protection, low income, and low productivity activities with no rules/regulation. Despite all these challenges, these women are very positive about their employment and business. While informality offers greater labour flexibility, it can also exacerbate economic inefficiency and labour vulnerability. There are separate policy options for formalising workers and firms. To maximise the positive and minimise the negative, indiscriminate formalisation is ill-advised. The importance of local context in policy design is also highlighted.

Solat or prayer, as one of the five pillars of Islam, and it is associated with bio-psycho-social benefits in Muslim patients. Â Many Muslim patients neglected solat while being hospitalized as they are unaware of the convenience (rukhsoh) available for them. Ibadah Friendly Hospital Courses have been conducted in different states of Malaysia to impart knowledge to the hospital staff who can in turn educate their patients. This study aims to construct a content-validated assessment tool and to assess the effectiveness of a state-level Hospital Mesra Ibadah course. Materials and methods: A self-administered questionnaire was constructed and content-validated by a panel of three experts (two religious teachers and one consultant spine surgeon). All 15 questions achieved item-level content validity index (I-CVI) of 1.00 after two rounds of validation. The questionnaires were distributed to participants of a state-level Hospital Mesra Ibadah course to compare the participants’ pre-course test score and post-course test score. Results: A total of 88 participants (48.9%) were included in this study. There was a significant difference in the pre-course test mean score and post-course test mean score among the participants. There was also a significant reduction of unsure answer after the course. There was no significant association found between the gender, place of working and occupations with the pre-post test score difference. Conclusion: This study demonstrates that the Hospital Mesra Ibadah course is effective in imparting as well as consolidating the knowledge among participants, hence it should be routinely organized to benefit more participants.

Venous malformations (VM) of vulva, perineum and pelvis are uncommon condition which may present with cutaneous varices or aesthetically disabling swelling of external genitalia. Herein, we report a young woman who presented with a large left vulva bluish tinged swelling, progressively increasing in size since birth. Computed tomography of the pelvis and lower limbs confirmed the diagnosis of extensive VM of pelvis and perineum. She underwent selective angiogram which revealed venous malformations of left vulva and gluteal region with no arterial supply to the lesion. Surgical excision was performed but complicated with bleeding which necessitate multimodal hemostatic procedures and blood transfusion. There is no recurrent swelling after 5 years follow up. Surgical excision of vulvar venous malformation offer good cosmetic outcome. However, appropriate planning with axial scan, angiogram and operative technique including multimodal hemostatic measure are important steps to achieve good result with no recurrence. We discussed on challenges on management of this case in relation to the currently available literature.

Repair and maintenance in power distribution is an important factor that
affects the continuous productivity services and power efficiency in electrical
supply systems. Thermographic inspection has been often used as a
maintenance tool, as it allows detection of early-stage failure from the system
in electrical distribution. Failure in the system can lead to catastrophic
failure like a high-voltage arc fault. The presence of fault is caused by the
higher temperature of the instrument that leads to the formation of hotspots.
The use of infrared inspection is useful in detecting the hotspot that is hardly
noticeable. It helps to overcome the problems that arise during operation
and maintenance in the distribution systems. In this research, a fault
detection system is proposed with the application of Artificial Neural
Network (ANN) in identifying faults on electrical equipment. This method
was trained by using the temperature parameter on the IR images taken from
TNB Distribution. As a result, it will lead to faults detection. Thus, the
purpose of this project is to ensure the correct recommendation of corrective
actions in the maintenance procedure of the electrical system. The actions to
the detection of faults taken are based on the results of the temperature
measured. The neural network training performance for the temperature of
hotspot detection was developed with a minimum error of 0.00084165 MSE
at epoch 39. The study shows the best-fitting allows detection of early-stage
failure. It can be concluded that the current method in conducting the
prediction process by using Thermographic inspection is suitable for
electrical equipment based on the training result.

Accidents caused by fire can result in serious injury and damage to personal
property. Fire hazards are not always obvious in and around the home, so
accidents involving fire are often unexpected and sudden. The main purpose
of fire detection monitoring systems using Raspberry Pi isto provide an early
warning for homeowners, to take immediate action to stop or eliminate fire
effects as soon as possible. The system called Ifire provides a real time
monitoring system, where they can receive push notification once the sensors
are triggered. This system is a combination of technology using Internet of
Things devices like temperature and humidity sensors (DHT11), infrared
(IR) flame sensor, and mobile application. This system is an application that
uses geo-fencing technology for homeowners, to find the nearest fire
department to give a fast emergency response. Besides, it could help fire
department staff to receive homeowner addresses and navigate directly to
the location. The project was tested with functionality testing and network
performance testing to make it work properly and successfully. The network
performance testing shows the distance between Raspberry Pi and the access
point will decrease when the distance increases. In addition, the response
time testing result also shows the time during peak hour will decrease the
performance. For future enhancements this Internet-based monitoring
system will need security protection to prevent false fire information.

Tabiat langkau waktu makan adalah kaedah lazim untuk mengawal diet. Namun, amalan kaedah permakanan ini oleh pesakit diabetes melllitus (T2DM) masih belum diketahui berikutan kekangan kajian. Matlamat utama kajian ini adalah untuk mengenal pasti selazim mana pesakit T2DM melangkau waktu makan. Kaitannya dengan faktor sosiodemografi dan klinikal, HbA1c, makan di luar rumah dan kecelaruan gaya pemakanan turut dikaji. Kajian keratan lintang ini telah dijalankan pada tahun 2015 dalam kalangan 203 pesakit di klinik kesihatan awam di Kuala Lumpur. Borang soal selidik yang diisi sendiri oleh subjek termasuk borang Skala Kecelaruan Gaya Pemakanan dalam Bahasa Melayu. Seramai 41.4% subjek kerap melangkau waktu makan dan 61.6% subjek sering makan di luar. Hanya 2% sahaja yang mempunyai masalah kecelaruan gaya pemakanan. Regresi logistik berbilang menunjukkan subjek berbangsa Cina mempunyai kaitan yang kuat dengan tabiat melangkau waktu makan berbanding dengan subjek berbangsa Melayu (nisbah ganjil selaras: 0.36; 95% sela keyakinan: 0.16-0.77; nilai p: 0.009) setelah mengambil kira faktor usia, status pekerjaan, tahap pendidikan, HbA1c, komplikasi, jenis rawatan, makan di luar dan kecelaruan gaya pemakanan. Kesimpulannya, tabiat melangkau waktu makan merupakan satu amalan lazim begitu juga dengan makan di luar rumah. Namun, kecelaruan gaya pemakanan jarang dijumpai. Tabiat melangkau waktu makan tiada kaitan dengan amalan pemakanan ini dan juga kawalan gula dalam darah. Faktor budaya dan keagamaan berkemungkinan mempengaruhi amalan pemakanan individu. Kajian lanjut perlu dijalankan bagi mengenal pasti tahap keselamatan dan penerimaan berkaitan dengan amalan ini. Walau bagaimanapun, kesannya daripada sudut klinikal perlu diperiksa dengan teliti untuk mengelakkan komplikasi kesihatan.

Grief is defined as ‘the internal experience of a person to the loss of something loved and valued’. It is a normal and expected reaction to loss. While anticipatory grief is defined as ‘an emotional response that is experienced before a true loss’, a concept focusing on that a person might experience grief when the loss of a close loved one was anticipated, but had not yet occurred. The history of Abu Bakr r.a. was reviewed especially from the period of a few months before and recently after the death of the prophet s.a.w. It was noted that he appeared strong while others were down grieving upon the news of the prophet s.a.w.’s death. It was also noted that Abu Bakr r.a. has been grieving when he anticipated that the prophet was going to die. Literatures on anticipatory grief were reviewed. Evidence are conflicting on the role of anticipatory grief. Factors that lead to these differences will be reviewed. The protective factors in Abu Bakr r.a. that helped maintain his composure after the death of prophet Muhammad s.a.w. and later led him to be pledged as the first caliph of the Muslim nation will be discussed.

Anaerobic wastewater treatment technology has become one of the most popular technologies due to its economic and environmental benefits. Therefore, a reliable method to study the specific methanogenic activity (SMA) of anaerobic sludge is presented using SMA test. This test helps to determine suitable organic loading rate (OLR) to the anaerobic process. Meanwhile, SMA act as a benchmark to the anaerobic system performance where a slight change in SMA stipulate the accumulation of inhibitory substances from influent wastewater. One of the possible substances that inhibit the anaerobic digestion process is the presence of excessive light metal ions such as sodium (Na+) from the wastewater. The objective of this research was to investigate the specific methanogenic activity of anaerobic sludge in anaerobic filter and anaerobic digester as well as to compare and analyze anaerobic methanogenic bacteria under the effect of potentially inhibitory compound in both anaerobic digester and anaerobic filter. Two sources of inoculums (one from the anaerobic digester and one from the anaerobic filter) were adapted with sodium with varied range of concentrations which was 0 to 5 g Na + /l, before conducting SMA test by means of pressure differences. For the anaerobic digester, the SMA varied from 0.25 to 0.31 g COD/g VS.day meanwhile for the anaerobic filter, the SMA varied from 0.40 to 0.51 g COD/g VS.day. The result obtained confirmed that sludge from POME have better tolerance towards sodium than influents from petrochemical wastewater.

Pressure relief system is a system to prevent overpressure inside protected equipment that exceeds its maximum allowable working pressure (MAWP) to disposal treatment. Relief system is designed on two different plant case studies, which are dimethyl-ether and ethylbenzene plants by using conventional design procedure. Nevertheless, the conventional design steps are not considering cost optimization of plant installed with relief system. Thus, the design pressure of protected equipment, piping diameter, and disposal treatment is set to be manipulated variables to determine the cost minimization. Pressure drops of inlet piping and backpressure are as constraint variables due to standard requirements. The standards state that inlet piping pressure drops should be below 3% of set pressure and outlet piping pressure drop to set pressure percentage based on range to determined types of the relief valve to be used. From that, optimum plant design with consideration of pressure relief system’s installation can be achieved by calculating the total cost of plant designed with relief system when set pressures are changed. As a result, dimethyl-ether plant shows a minimum point of the total cost at 170% of set pressure increment, which is lower than its original design. On the other hand, ethylbenzene plant gives optimum point at original design as the total cost is higher at set pressure increment.

This study analyses the sampling performance of three benthic sampling tools
commonly used to collect freshwater macroinvertebrates. Efficiency of qualitative D-frame
and square aquatic nets were compared to a quantitative Surber sampler in tropical
Malaysian streams. The abundance and diversity of macroinvertebrates collected using
each tool evaluated along with their relative variations (RVs). Each tool was used to
sample macroinvertebrates from three streams draining different areas: a vegetable farm,
a tea plantation and a forest reserve. High macroinvertebrate diversities were recorded using the square net and Surber sampler at the forested stream site; however, very low
species abundance was recorded by the Surber sampler. Relatively large variations in the
Surber sampler collections (RVs of 36% and 28%) were observed for the vegetable farm
and tea plantation streams, respectively. Of the three sampling methods, the square net
was the most efficient, collecting a greater diversity of macroinvertebrate taxa and a
greater number of specimens (i.e., abundance) overall, particularly from the vegetable
farm and the tea plantation streams (RV
