Abstract

Unreinforced Masonry (URM) wall is vulnerable in resisting horizontal load suchas wind and seismic loading. It is due to the low tensile strength of masonry, the mortar connection between the brick units. URM structures are still widely used in the world as an infill wall and commonly constructed with door and window openings. This research aimed to investigate the behaviour of URM wall with openings when horizontal load acting on it and developed load-drift relationship of the wall. The finite element (FE) method was chosen to numerically simulate the behaviour of URM with openings. In this research,ABAQUS, commercially available FE software with explicit solver was employed. In order to ensure the numerical model can accurately represent the behaviour of an URM wall, the model was validated for URM wall without openings using available experimental results. Load displacement relationship of numerical model is well agreed with experimental results. Evidence shows the same load displacement curve shape obtained from the FE model. After validating the model, parametric study conducted on URM wall with openings to investigatethe influence of area of openings and pre-compressive load on the horizontal load capacity of the wall. The result showed that the increasing of area of openings decrease the capacity of the wall in resisting horizontal loading. It is also well observed from the result that capacity of the wall increased with the increasing of pre-compressive load applied on the top of the walls.

Abstract

Pegagan (Centela asiatica [L] Urban) contains alkaloid, flavonoid, saponin, triterpenoid and tannin that have antibacterial activity. Staphylococcus aureus and Klebsiella pneumoniae are most common of bacteria that cause pneumonia. This study conducted t odetermine the effect of ethanol extracts of pegagan in inhibiting the growth of S. aureus and K. pneumoniae that caused pneumonia. The type of this study is a laboratory experiment using a completely randomized design (CRD). Testing of inhibitory growth effect was measured by Kirby Bauer disc diffusion method. The results showed that ethanol extracts of pegagan at 12.5%, 25%, 50% and 75% concentrations formed inhibition zones on the growth of S. aureus, on average respectively of 7.00 mm, 9.20 mm, 13.20 mm, and 14.50 mm, whereas on the growth of K. pneumoniae, it didn’t form any inhibition zone. The results of ANOVA and Duncan (α=1%) tests showed that ethanol extracts of pegagan at all concentrations made a significant difference in inhibiting the growth of S. aureus compared to negative and positive control. The ability of ethanol extracts of pegagan to inhibit the growth of S. aureus at 12.5% and 25% concentrations categorized as no inhibitory growth effect, whereas 50% and 75% concentrations categorized as weak inhibitory growth effect. While the ethanol extracts of pegagan at all concentrations of the tests categorized as no inhibitory growth effect for K. pneumoniae. It can be concluded that ethanol extracts of pegagan inhibit the growth of S. aureus, but do not inhibit the growth of K. pneumoniae.

Abstract

Polyethersulfone (PES) membranes were prepared via phase inversion method. The effect of polymer concentration on the morphology of the fabricated membranes were studied. Furthermore, the effect of transmembrane pressure (TMP)was also studied on the filtration performance of biodiesel purification. The morphology of fabricated PES membrane was analyzed by using Scanning Electron Microscopy (SEM) indicated that the PES membranes had skin layer on the membrane surface and pores layer on the bottom surface. The permeability coefficient (Lp) of PES membranes were about 21-40 L/m2.h. The Molecular Weight Cut Off (MWCO) test shows that the rejection of dextran solution with the molecular weight 18,8Kda was above 90%. The water contact angle of PES membranes was measured to know the hydrophilicity of PES membrane. The water contact angle was about 73oconfirmed that the PES membrane was hydrophobic. The increasing ofTrans-membrane Pressure (TMP) had a significant effect on the permeability of membrane which isthe permeability of biodiesel increases by increasing the TMP. The maximum of flux was obtained about 110 ml/sec

Abstract

This paper conceptually analyzed the concept of empowerment using the strategies of Walker Avant (2005) the objective is to clarify the meaning of the concept and to clearly identify empowerment characteristic that will provide consistent definition for practice and future research. Empowerment is defined and examined using relevant resources of literatures and selected empirical referents that described empowerment as a complex and multidimensional concept. Within nursing context empowerment can be conceptualized as a combinations of attributes that relate to the empowerer (the client), and attributes that belong to the empowered (that can be both client and nurse). In a broad sense, empowerment is the process that involves two parties or more that are dynamic and multidimensional, where the activity is sharing power, and create mutual relationship, making it possible for people to increase their sense of control and can help optimize their independence. To clearly distinguish between empowerment and other concepts, related concepts are presented and by using related case we compared the concept with empowerment. The analysis demonstrates that the defining attributes of the concept are (1) a helping process, (2) A partnership which values self and others, (3) mutual decision making, identified resources and set goals, (4) opportunity and authority, (5) open communication, (6) freedom to make a choice and accept responsibility and (7) should come with honesty, openness and genuineness.   Antecedents of the concept are (1) respect, (2) trust, (3) education or previous knowledge or experience, (4) interpersonal and communication skills, (5) acceptance of people as they are, and (6) shared visions.  Consequences of empowerment are (1) enhanced and improved self esteem, (2) ability to set goals and reach goals, (3) a sense of control over life and change process, (4) a sense of hope for the future, (5) increase problem solving ability, (6) better communication and leadership skills, and (7) have the autonomy and responsibility. To understand the concept better all the defining attributes are identified and applied in the model case, while borderline, related and contrary case are also used to explicate the concept. Empirical referents were also provided. There are limited tools available to measure empowerment, which create the availability to develop tools to measure empowerment based on the context. In conclusion, empowerment is useful and significant concept for nursing practice, administration, education and research. Empowerment emphasizes in engaging the resources within self to create well - being. Therefore, clients need to become aware of their resources and need to purposefully participate in working toward the attainment of heath goals

Abstract

Green peach aphid (MyzuspersicaeSulze) represents one of the major pest affecting decreased production which found in different potato fields in Karo highland. Decreasing incurredin two ways: the direct damages that are caused by the insectfeeding on the plants and the indirect damages caused to potato planting materials as a virus vector. There are different methods for controlling green peach aphids, all of them relying inthe use of chemicals and this method makes food production contaminated by pesticide residu. So, using non-chemical methods of cultivation contribute to “ecological” food production.Intercropping is one way of reducing pest insect populations in such vegetable crops.This study was conducted to determine the population dynamics of Myzuspersicae (Sulzer) on Intercropping system of potato plant with other vegetables plant on Karo Highland. The host plant was cultivar Granola of potato and the intercropping plant respectively were cabbage, mustard, celery, onions, carrot and bean. The results showed that M. persicae was consistently at different densities in different intercropping plant on potato. The aphid was first recorded at three week until planting. The kind of inter cropping culture plants significantly reduced the number of aphid. The lowest number of aphid found respectively inintercroppingpotatoesandmustard, potatoesandonions, andpotatoesandcelery. There was 0.80 aphids /leaf, 1,12aphids/leaf, 1,48 aphids/leaf. At the 2nd observation found the number of aphid was lowest atpolyculture potatoes and mustards were 1,68 aphid/leaf, at popatoes and onions were 3,28 aphid/leaf, at popatoes and celery 3,00 aphid/leaf. The number of aphids steadily increased with significant at differencesintercroppingplant till the 3rd observation (9 weeks until planting) respectively where 2,80aphid/leaf, 3,42 aphid / leaf and 4,20 aphid/leafwere recorded. Observation for natural enemies of M. persicaeshowed that fewnatural enemiesfound in theagro-ecosystem. There are Episyrphusbalteatus, Chrysoperlacarnea, phidiusmatricarieae and Coccinellaseptempunctata. The population density of all of the natural enemies was highest at polyculture than monoculture of potato. After that, as the population of M. persicae started decline, the same trend was followed by all of its natural enemies.

Abstract

Anaplasmosis, also known as yellow fever, is an infectious parasitic disease of cattle caused by the protozoan Anaplasma marginale. Anaplasma marginale infects the erythrocytes and causes severe anaemia, weakness, loss of appetite, fever, depression, abortion, decreased milk production, constipation, jaundice and sometimes death. In Malaysia, data on A. marginale infection is still behind compared to other parasites such as nematodes. Anaplasmosis in livestock has received little attention in Malaysia with only occasional reports in cattle. In addition, the determinants of tick- and fly-borne transmission are not well understood. Looking into this possibility, this study was carried out to investigate and to compare the prevalence rate of bovine anaplasmosis in Malaysia. A seroprevalence study on bovine anaplasmosis was conducted at the Veterinary Research Institute, Malaysia. Sera of various cattle breeds were collected from farms and abattoirs to be tested for the presence of A. marginale. Competitive enzyme-linked immunosorbent assay (c-ELISA) Anaplasma antibody test kits by VMRD, Inc. were used for this study, where antibodies to A. marginale from sample sera inhibit the binding of horseradish peroxidase (HRP)-labelled monoclonal antibody to the Anaplasma antigen coated on the plastic wells. A total number of 267 serum samples were tested and 79.4% were positive for bovine anaplasmosis. Results showed that the infection percentage is 100% in Pahang while the state with lowest infection percentage is Sabah with 59.2%. A comparison is done between Peninsular Malaysia with Sabah and Sarawak. The infection percentage in Peninsular Malaysia is higher at 87% while Sabah and Sarawak has an infection percentage of 60%. However, there is no significant difference in the rate of infections. The high number of cases in Peninsular Malaysia may be caused by the lack of strict control measures due to dependence on modern tools and drugs, while cases in Sabah and Sarawak may be due to traditional practices carried out frequently that may cause iatrogenic transmission. More samples should be obtained in order to validate the results. In addition, annual studies must be done to monitor the status of A. marginale prevalence in local cattle that is medically and economically significant to Malaysia.

Abstract

This research was aimed at determing the effect of fish bone gelatin supplementation on protein content and consumer acceptability of rice-based traditional foods. Three types of traditional foods, i.e. dange, surabeng andonde-onde were supplemented with fish bone gelatin at concentrations of 0, 5, 10, 15 and 20% (w/w) with three replicates for each treatment and for each type of foods. The protein contents were analyzed using micro-kjeldahlmethod whereas the consumer acceptability was determined organoleptically by employing 15 panelists. Data on the protein contents were subjected to ne-way Annova, while those of consumer acceptability were analyzed descriptively using percentage of frequency of occurrence. Results indicated that addition of fish bone gelatin significantly increased the protein contents of the foods and that the protein content of each type of foods was differ between the gelatin concentration treatments. The protein contents of foods were increased by 1.68-4.77 folds, and may be predicted using a simple regression formula: Y=0.578x + 6.037, R2=0.978 for dange; Y=0.660x + 4.068, R2=0.992 for surabeng; and Y=0.554x +5.39, R2=0.967 for onde-onde. The level of consumer acceptability showed that the addition of 10% of fish bone gelatin into each of the three traditional foods produced food products with good acceptability levels.

Abstract

This study aims to describe the condition of Tripa Peat Swamp Forest (TPSF) in the Province of Aceh Indonesia that has been converted from forest to oil palm plantation and mixed farms. The results showed that the degradation of the peat soil and the environment have occurred in the TPSF. Degradation of peat is characterized by the occurrence of changes in water holding capacity and changes in chemical and physical properties of soil. Environmental degradation is characterized by changes in groundwater levels and land subsidence. TPSF restoration efforts can be carried out in accordance with the directives of land use and land conservation and water management

Abstract

The adsorption of lead(II) ions from aqueous solution with breadfruit’s bark by unmodified and modified with citric acid was investigated. The results by using adsorbent dosage 20 g/L indicated the   adsorption efficiency was up to 99%, and the best result is obtained about 99,963% when adsorbate is  conducted with modified bark for 90 minutes. The adsorption behavior by modified bark followed the Langmuir isotherm model and the Freundlich isotherm model for modified bark. The maximum adsorption capacity of lead(II) ions are 34,98 mg adsorbate/g adsorbent for unmodified bark when contact time is 60             minutes. The influence of contact time showed that adsorption reached the equilibrium rapidly. A batch adsorption model followed the pseudo second order kinetic.

Abstract

Household poisoning is a public health issue in developing countries. This study was conducted to determine the perceptions of residents in Pasay City towards household poisoning, using a quantitative descriptive design, through a survey-interview data collection method. The study found that 58% of the respondents perceived improper food preparation as the most common source of poisoning, while 14% reported the absence of poisonous substances in their homes. Only 64% reported seeking medical consult as a priority intervention. Lastly, 83% identified proper labeling as a prevention method for poisoning. The researchers recommend increased public awareness regarding household poisoning, more visibility of therole of NPMCC in the community, and a second interventional phase of the study.
