Protein structure prediction using robust principal component analysis and support vector machine

Existence of bioinformatics is to increase the further understanding of biological process. Proteins structure is one of the major challenges in structural bioinformatics. With former knowledge of the structure, the quality of secondary structure, prediction of tertiary structure, and prediction function of amino acid from its sequence increase significantly. Recently, the gap between sequence known and structure known proteins had increase dramatically. So it is compulsory to understand on proteins structure to overcome this problem so further functional analysis could be easier. The research applying RPCA algorithm to extract the essential features from the original highdimensional input vectors. Then the process followed by experimenting SVM with RBF kernel. The proposed method obtains accuracy by 84.41% for training dataset and 89.09% for testing dataset. The result then compared with the same method but PCA was applied as the feature extraction. The prediction assessment is conducted by analyzing the accuracy and number of principal component selected. It shows that combination of RPCA and SVM produce a high quality classification of protein structur

Umbrella is a primarily a device to keep people dry in rain and shade a person from the sun. Mostly, it can be seen that umbrella is used by women. In the market, there is abundance of designs, colours and functions that can be choose. The improvement in our design may lead umbrella to a better user friendly and easy to carry to anywhere. Basically, the new invention that we apply to our umbrella is that it can expand from the small size to a larger size just by clicking the button provided in the umbrella's handle. One of the reasons that we come out with this idea is that we notice most of the students carry their own umbrella to the class which the size of the umbrella usually is small and fit for 1 person only. By the time of raining, they cannot share the umbrella with their friends and we found out, the umbrella's owner also may get wet because of the small umbrella. Therefore, our group come with the idea of a helping-hand solution by having an expand umbrella. As we gather the information that is heeded, we eventually come out with some of the fantastic ideas that never had been explored by the other designers out there. Our new invention idea is that by having just 1 umbrella, you can share it with your friends. The canopy for our umbrella can be enlarged at 2 times. Basically, the size will be small that fit for 1 person. Then it can enlarged to the medium size that fit for 2 or persons, and again, the canopy can enlarged to the large size that will be fit for 4 or 5 persons. Other than that, this umbrella can also be a table umbrella. The umbrella's weight is not heavy although it has added the canopy enlargement which it is easy to be carried to everywhere

Issues and challenges of joint management body in high-rise residential facilities management: the developers

High demand for housing and land scarcity in the town area has increased the provision of High-rise Residential Buildings (HrRB). HrRB has different owners but shares the same land and common facilities. Its common facilities are generally prone to damages either from “wear and tear” or vandalism. Therefore, Thus, maintenance works of HrRB and its common facilities should be done properly and periodically by experienced property management company. By the introduction of new laws and implementation thereof, Joint Management Body (JMB) was established to govern the rights and obligations of three parties’ i.e., purchasers, developer, and facilities manager. The residents constantly point fingers to property management if there is dissatisfaction on the damage restoration and maintenance work done. In fact, strata management issues were brought to court by owners for adjudication, such as ACN Infra Sdn Bhd v Perbadanan Pengurusan Kondominium Subang Indera [2020] 3 AMR 741, duties of management corporation in repairing defects were debated. In another case of Muhamad Nazri Muhamad v. JMB Menara Rajawali & Anor Civil Appeal No: W-02(NCVC)(A)-205710/2018, owners disputed whether the management body could charge a different rate of maintenance charges for different properties in HrRB. Hence, this paper intends to address the issues and challenges related to property management. This research is based on a questionnaire survey from the developer’s perspective. An Average Index analysis was used to rank the level of significance issues, challenges, and major roles of JMB. The key roles of developers in JMB under Strata Property Management were highlighted in order to ensure the common facilities for HrRB more manageable in its damage recovery

​​The utilisation of Antarctic microalgae isolated from Paradise Bay (Antarctic Peninsula) in the bioremediation of diesel

Research has confirmed that the utilisation of Antarctic microorganisms, such as bacteria, yeasts and fungi, in the bioremediation of diesel may provide practical alternative approaches. However, to date there has been very little attention towards Antarctic microalgae as potential hydrocarbon degraders. Therefore, this study focused on the utilisation of an Antarctic microalga in the bioremediation of diesel. The studied microalgal strain was originally obtained from a freshwater ecosystem in Paradise Bay, western Antarctic Peninsula. When analysed in systems with and without aeration, this microalgal strain achieved a higher growth rate under aeration. To maintain the growth of this microalga optimally, a conventional one-factor-at a-time (OFAT) analysis was also conducted. Based on the optimized parameters, algal growth and diesel degradation performance was highest at pH 7.5 with 0.5 mg/L NaCl concentration and 0.5 g/L of NaNO3 as a nitrogen source. This currently unidentified microalga flourished in the presence of diesel, with maximum algal cell numbers on day 7 of incubation in the presence of 1% v/v diesel. Chlorophyll a, b and carotenoid contents of the culture were greatest on day 9 of incubation. The diesel degradation achieved was 64.5% of the original concentration after 9 days. Gas chromatography analysis showed the complete mineralisation of C7–C13 hydrocarbon chains. Fourier transform infrared spectroscopy analysis confirmed that strain WCY_AQ5_3 fully degraded the hydrocarbon with bioabsorption of the products. Morphological and molecular analyses suggested that this spherical, single-celled green microalga was a member of the genus Micractinium. The data obtained confirm that this microalga is a suitable candidate for further research into the degradation of diesel in Antarctica

Alteration in the functional organization of the default mode network following closed non-severe traumatic brain injury

The debilitating effect of traumatic brain injury (TBI) extends years after the initial injury and hampers the recovery process and quality of life. In this study, we explore the functional reorganization of the default mode network (DMN) of those affected with non-severe TBI. Traumatic brain injury (TBI) is a wide-spectrum disease that has heterogeneous effects on its victims and impacts everyday functioning. The functional disruption of the default mode network (DMN) after TBI has been established, but its link to causal effective connectivity remains to be explored. This study investigated the differences in the DMN between healthy participants and mild and moderate TBI, in terms of functional and effective connectivity using resting-state functional magnetic resonance imaging (fMRI). Nineteen non-severe TBI (mean age 30.84 ± 14.56) and twenty-two healthy (HC; mean age 27.23 ± 6.32) participants were recruited for this study. Resting-state fMRI data were obtained at the subacute phase (mean days 40.63 ± 10.14) and analyzed for functional activation and connectivity, independent component analysis, and effective connectivity within and between the DMN. Neuropsychological tests were also performed to assess the cognitive and memory domains. Compared to the HC, the TBI group exhibited lower activation in the thalamus, as well as significant functional hypoconnectivity between DMN and LN. Within the DMN nodes, decreased activations were detected in the left inferior parietal lobule, precuneus, and right superior frontal gyrus. Altered effective connectivities were also observed in the TBI group and were linked to the diminished activation in the left parietal region and precuneus. With regard to intra-DMN connectivity within the TBI group, positive correlations were found in verbal and visual memory with the language network, while a negative correlation was found in the cognitive domain with the visual network. Our results suggested that aberrant activities and functional connectivities within the DMN and with other RSNs were accompanied by the altered effective connectivities in the TBI group. These alterations were associated with impaired cognitive and memory domains in the TBI group, in particular within the language domain. These findings may provide insight for future TBI observational and interventional research

Concentration of biopetrol synthesized from stearic acid through catalytic cracking using zeolites as catalyst

Biopetrol is an alternative fuel that have same characteristic with the petrol in term of its molecular formula, or to be specifically the octane number of molecules. In this research, the objective is to study the effect of catalyst which is Zeolite to enhance the production of Isooctane from Stearic Acid. The experiment starts with heating the Stearic Acid until it melts at 69.6oC, and then 20 grams of zeolite being added and the heating process proceed until the temperature reached 98oC as the isooctane produce will evaporates. The next experiment is repeated by with different mass of zeolite which is 10 grams, 5 grams and 1 gram. This reaction is called as Catalytic Cracking, where the zeolite will enhance the production of Isooctane. From the result obtained from the Gas Chromatogram result, the percentage of actual concentration of isooctane obtained for 20 g Zeolite is 3.95%, 10g zeolite is 2.769%, 5g zeolite is 3.387% and 1g Zeolite is 2.946%. The highest percentage of Isooctane produced is Stearic Acid distillate with 20g Zeolite, which is 3.95%. This experiment could be more effective by applying dynamic state concept to the process
