Study of Energy Performance in Malaysian Public Hospital using Power Query

In 2016, the Ministry of Health (MOH), Malaysia, initiated a sustainable program that includes activities for sustainable energy management at all 145 buildings under the MOH. The focus of the sustainable energy management program is to target these buildings to reduce their annual energy consumption by 10% by 2018. The target implementation of a sustainable energy management program includes achieving 3-star EMGS certification within 5 years. By December 2022, 135 have achieved two-star certification with the requirement to achieve at least 5% energy consumption savings. By 2019, the 118 buildings that embarked on EMGS certification had achieved 22.62% energy consumption savings. District and specialist hospitals achieved 23%–24% savings in 2019. The largest energy consumption in MOH buildings is for room cooling, which is contributed by air conditioning and mechanical ventilation (ACMV) equipment. The implementation of a sustainable energy management program has contributed to energy cost savings of RM21 million per year to MOH energy bills in 2019

Single-mode fiber coated with zinc oxide (ZnO) nanorods for H2 gas sensor applications

A Hydrogen (H2) gas sensor was successfully developed using optical fiber coated with Zinc Oxide (ZnO) nanorods. The single-mode fiber (SMF) used as a sensing device has been prepared by etching the SMF fiber and coated with ZnO nanorods. The etching of the fiber was performed using hydrofluoric acid (HF) to enhance the evanescent field around the fiber core. The ZnO nanorods were prepared by hydrothermal method through seeding and growth solution technique. The diameter of cladding and core are 125 μm and 8 μm, respectively, before etching and goes down to 11μm after etching. Around 2 cm of ZnO nanorods were coated in the middle of the etched fiber. The sensing layer was characterized through Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray (EDX) and X-Ray Diffraction (XRD) to verify the properties of ZnO. The developed sensor's response and recovery time were observed to be 7 min and 3 min, respectively, for a low concentration of 0.25% H2 gas. The aim of this study is to understand the gas sensing properties towards the spectral intensity variations in etched optical fiber coated with ZnO nanorods

Numerical Study of a Left Ventricular Assist Device (LVAD) With Different Blade Heights and Tip Clearances

One treatment modality for heart failure is to employ a mechanical heart assist device to increase blood flow to peripheral organs. There are various kinds of axial and centrifugal type mechanical pumps available for implantation depending on patient condition. Axial pumps are smaller in size comparatively, although centrifugal pumps have the advantages of lower rotational speed as well as better maintaining any native blood flow pulsatility. This work presents the results of the numerical study of the centrifugal blood pump configured as a Left Ventricular Assist Device (LVAD). The pump design utilized standard industrial centrifugal pump design principles but applied to smaller sized blood pumps. Flow characteristics are modelled using 3-dimensional steady state models operating at design speed of 2000 rpm using Newtonian blood properties for the fluid. Two design parameters of the pump are studied, the impeller blade height and tip clearance resulting in nine model variants. Analysis includes the hydrodynamic performance of the pump and the flow characteristics in the pump. A haemolysis prediction model quantifying red blood cell stress from exposure time and shear stress was used for quantitative predictions of haemolysis within the blood pump. Blood damage estimation was calculated along each path-line and averaged to a single value. By using a ranked selection method, the model with the 15 mm blade height and 800 µm tip clearance was selected as the preferred configuration with Haemolysis Index of 0.01 mmHg, efficiency of 58% at 104 mmHg outlet pressure

Electrochemical DNA biosensor for detection of porcine oligonucleotides using [Ru(bpy)2PIP]2+ complex

An electrochemical DNA biosensor for detection of porcine oligonucleotides based on ruthenium (II) complexruthenium(II) complex, [Ru(bpy)2(PIP)]2+, (bpy = 2,2’bipyridine, PIP = 2-phenylimidazo[4,5-f[[1,10-phenanthroline]) as label redox have been developed. The study was carried out by immobilization of porcine aminated DNA probes sequences on screen printed electrode (SPE) modified with succinimide-acrylic microspheres and [Ru(bpy)2(PIP)]2+ to detect DNA hybridization event. The electrochemical detection by redox active ruthenium (II) complex was measured by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The results indicate that the interaction of [Ru(bpy)2(PIP)]2+ with hybridization complementary DNA has higher response compared to single-stranded and mismatch complementary DNA. Under optimized condition, this porcine DNA biosensor shows linear response range towards target DNA within range of 1 x10 -5 uM to 1x10-13 uM

Skripsi ini adalah untuk mengungkap persoalan tentang bagaimana orang minang migrasi atau berpindah ke Tanah Melayu, kesan migrasi mereka terhadap budaya setempat di Negeri Sembilan, seterusnya apakah perbedaan yang muncul kesan dari penghijrahan Orang Minang terhadap tanah pusaka di Negeri Sembilan. Pendekatan penelitian yang digunakan dalam penelitian ini adalah pendekatan kualiltatif dengan menggunakan metode diskriptif. Instrumen pengumpulan data adalah melalui studi dokumentasi atau studi literatur. Jenis penelitian yang digunakan dalam kajian ini yaitu library research (kajian pustaka) supaya penulis dapat meneliti dan membahas kajian ini secara rinci dan membahas permasalahan ini dengan lebih mendalam. Dengan menggunakan data primer yaitu daripada kitab-kitab undang seperti Perlembagaan Persekutuan, Kanun Tanah Negara 1965, Undang-Undang Republik Indonesia Nomor 5 Tahun 1960, Undang-Undang Dasar Dasar Negara Republik, , manakala data sekunder yang merupakan data pelengkap atau pendukung yang diperoleh melalui buku-buku, jurnal dan juga artikel-artikel. Dalam penelitian yang dijalankan maka mendapati bahwa penghijrahan masyarakat Minangkabau ke Negeri Sembilan telah berlaku seawal abad ke-12 dimana perpindahan mereka ini telah menyebabkan budaya dan adat minangkabau mulai masuk dan dipraktekkan dalam oleh penduduk asal yang terdiri dari Melayu-proto. Hal ini turut menyebabkan tanah-tanah mulai menerima aturan adat sehingga tahap diiktiraf dalam perundang-undangan kerajaan Malaysia begitu juga di Republik Indonesia. Namun begitu bagi kedua Negara ini, dilihat terdapat perbedaan antara aturan perundang-undangan terkait tanah adat termasuklah pelaksanaannya sehingga perkara ini berdampak terhadap perkara yang berkemungkinan menghilangakan matlamat utama tanah adat

Influence of growth duration to the Zinc Oxide (ZnO) nanorods on single-mode silica fiber

Synthesizing Zinc Oxide (ZnO) nanorods by varying the growth duration will give effect to the morphology of ZnO nanorods which were grown by using microwave assisted hydrothermal method. The effect of different growth duration from 4 to 10 hours is investigated on the surface of bare silica optical fiber. The buffer coating of a silica fiber is stripped off for 5 cm to expose the area for the growth of ZnO nanorods. The ZnO nanorods were grown on the fiber by dipping the fiber into the prepared growth solution in a 90˚C microwave assisted hydrothermal synthesised. The physical characterization through field emission scanning electron microscopy (FESEM) results show the diameter of ZnO nanorods is about 75.0 - 93.8 nm and the length of ZnO nanorods ranges from 666.2 nm to 978.6 nm according to their growth duration. The uniform growth of 43.33 nanorods/(µm)2 reveals that the 10 hours of growth duration performs the highest density growth of ZnO nanorods. The amplified spontaneous emission (ASE) peaking at 1550 nm is used to investigate the effect on the light intensity in the optical fiber with coated and uncoated ZnO for optical characterization. The ASE spectrum shows that the light intensity decreases with the growth durations due to the light scattering effect
