Hyperspectral Imaging of Forest Resources: The Malaysian Experience

Science.gov (United States)

Mohd Hasmadi, I.; Kamaruzaman, J.

2008-08-01

Remote sensing using satellite and aircraft images are well established technology. Remote sensing application of hyperspectral imaging, however, is relatively new to Malaysian forestry. Through a wide range of wavelengths hyperspectral data are precisely capable to capture narrow bands of spectra. Airborne sensors typically offer greatly enhanced spatial and spectral resolution over their satellite counterparts, and able to control experimental design closely during image acquisition. The first study using hyperspectral imaging for forest inventory in Malaysia were conducted by Professor Hj. Kamaruzaman from the Faculty of Forestry, Universiti Putra Malaysia in 2002 using the AISA sensor manufactured by Specim Ltd, Finland. The main objective has been to develop methods that are directly suited for practical tropical forestry application at the high level of accuracy. Forest inventory and tree classification including development of single spectral signatures have been the most important interest at the current practices. Experiences from the studies showed that retrieval of timber volume and tree discrimination using this system is well and some or rather is better than other remote sensing methods. This article reviews the research and application of airborne hyperspectral remote sensing for forest survey and assessment in Malaysia.

CONTEMPORARY SLOVENIAN TIMBER ARCHITECTURE INTERNATIONAL RECOGNIZED

Directory of Open Access Journals (Sweden)

Manja Kitek Kuzman

2014-12-01

Full Text Available The book presents Slovenia' s contemporary timber architecture. Thanks to its abundant forests, Slovenia has preserved the tradition of wood construction. As much as 60% of its surface is covered by forests. Slovenia is also the third most forested country in Europe. The high share of forest-covered surface allows for a sustainable production of high-quality wood. In the past, wood was used primarily in the construction of farm buildings, but now timber architecture is used for everything from residences and office buildings to public buildings such as community centres and schools. Timber construction is becoming increasingly popular. Apart from larger companies taking this approach, a great number of wooden houses have sprung up, built either on personal initiative or with the support of carpenter workshops. Slovenian timber architecture has taken a new approach to environmental and energy-efficiency problems and received great international recognition. The book discusses over fifty projects built over a ten-year period, and includes descriptions, photographs, and plans. The projects include residential areas, administration, and office, as well as tourist, educational, and industrial buildings. Timber architecture is presented as an integral part of the Slovenian landscape. The monograph will be useful to designers and future experts in their planning of optimal timber buildings and will highlight the main benefits of using timber construction.

2017-04-01

Full Text Available International market requires producers to proof the legality of their wood products to address the issues of illegal logging and illegal trade. Timber Legality Verification System (TLVS has been prepared by the Government of Indonesia that covering the upstream and downstream wood industries. This paper aims to evaluate gaps in the implementation of TLVS policy and its impact on the sustainability of timber industry. This study was using gap, descriptive and costs-structure analyzes. The study was conducted in three provinces, namely: DKI Jakarta, West Java and D.I. Yogyakarta. Research found that the effectiveness of the TLVS implementation was low due to relatively rapid policy changes. This situation became disincetive for investments in timber business. Private sector perceived that TLVS policy should be applied in the upstream of timber business. Hence, the industry and market in the downstream have not been fully support to this system. Furthermore, TLVS policy implementation was considered ineffective by timber industry as well as private forest managers, especially by micro industry and smallholder private forests. This situation threatened the sustainability of timber industry and private forests. Therefore, Institutions should be strengthened in order to improve the quality of human resources and the competitiveness of products.

The Malaysian Intermodal Terminal System: The Implication on the Malaysian Maritime Cluster

Directory of Open Access Journals (Sweden)

Mohamad Rosni Othman

2016-06-01

Full Text Available The maritime sector in Malaysia is best known globally due to the Straits of Malacca and being a nation surrounded by sea. Malaysia also has a substantial maritime industry consisting of numerous shipyards, ports and terminal faculties, ship services and a plethora of other companies and institutions with maritime oriented activities and become essential components of the Malaysia's maritime clusters. Issues such as underutilised intermodal terminals, uneven proportions in the freight transport infrastructure and road and seaport congestions prevent Malaysian seaports from achieving their full potential in serving their respective hinterlands. The key factors to improve Malaysian dry port or intermodal terminals are transport network; container planning; competition; location and, externalities. The paper does not only present the critical challenges faced by Malaysian intermodal terminals especially dry ports and the implications for seaport competency but it also provides strategies to utilise the Malaysian freight multimodal system to amplify seaports
tm performance in serving their hinterlands. As such, this may warrant policy makers to devise a comprehensive national master plan for the maritime sector in order for Malaysia to further develop her maritime industry and economies.

Long term contracts signed in Slovak timber business

International Nuclear Information System (INIS)

Haluza, I.

2005-01-01

The Slovak timber business is changing. The state-owned company, SR Forests, which cuts more then 50% of Slovak timber has signed long term agreements with major domestic timber processing companies - Smrecina, the Rettenmeier Tatra Timber saw mill in Liptovsky Mikulas and two paper mills - Mondi SCP Ruzomberok and Kappa Sturovo. In the past, only quarterly contracts were signed. Now, for the first time, two-year contracts have been signed that should help the timber processing industry and the forestry sector. The General Director of Lesy SR (SR Forests), Karol Vins, hopes for better sale prices. Company headquarters wants to maintain better control of prices than under the old system of timber sales by its branches. In the opinion of the General Director of the Forestry Section at the Ministry of Agriculture, long term contracts will guarantee a stable delivery of timber to processing companies, giving investors in new production capacity a better position in negotiations with banks regarding financing. According to K. Vins, long term contracts have so far only been negotiated with major timber processing companies which are mostly controlled by foreign capital and therefore have good payment discipline. The Association of the Timber Processing Industry is unhappy regarding developments and Lesy SR has not invited domestic companies to these negotiations

Collaborative Monitoring of Production and Costs of Timber Harvest Operations in the Brazilian Amazon

Directory of Open Access Journals (Sweden)

Benno Pokorny

2005-06-01

Full Text Available Timber companies and policy makers in the Brazilian Amazon urgently need financial information on forest management. Results from a few experiments, case studies, and surveys have been groundbreaking, but are insufficient. A strategic partnership between timber companies and research organizations is needed to generate additional information. This paper presents a tool for monitoring production and costs of forest operations to facilitate such collaboration. The tool provides useful information for companies and, at the same time, generates reliable data for research. Selected results are presented on production, capacity, and costs to demonstrate the usefulness of the information that can be generated. These results are based on the first 2 years of implementation by a company in the State of Pará, Brazil. This pilot project confirmed that the tool is simple and relevant. Its successful implementation requires significant investment, and will be applicable only to companies interested in changing from conventional logging to reduced-impact logging, especially those seeking Forest Stewardship Council certification. Successful implementation of the tool will also depend on it generating readily understood and highly relevant results for the companies, and receiving extensive support during the first 2 years.

Nailed timber beams with I composed section

Directory of Open Access Journals (Sweden)

Jorge Luís Nunes de Góes

2003-01-01

Full Text Available The employment of built-up timber beams, made of commercial dimensions pieces, is becoming increasingly important in timber structures in Brazil, mainly due to the ever-growing scarcity of timber elements in larger sizes. The built-up system has vast application, from beams for residential buildings to girders for small bridges. The objective of this work is the theoretical and experimental study of nailed timber beams with composed cross section I. The design procedure of EUROCODE 5/93 and NBR 7190/97 are shown and evaluated, as well as the theory about the subject matter. The experimental evaluation of the theoretical models was made by means of bending tests in prototypes of built-up timber beams. The obtained results shows that the EUROCODE 5/93 procedure is the most indicated for evaluating effective bending stiffness, normal and shear stresses as well as the load on fasteners.

Rhythmic patterning in Malaysian and Singapore English.

Science.gov (United States)

Tan, Rachel Siew Kuang; Low, Ee-Ling

2014-06-01

Previous work on the rhythm of Malaysian English has been based on impressionistic observations. This paper utilizes acoustic analysis to measure the rhythmic patterns of Malaysian English. Recordings of the read speech and spontaneous speech of 10 Malaysian English speakers were analyzed and compared with recordings of an equivalent sample of Singaporean English speakers. Analysis was done using two rhythmic indexes, the PVI and VarcoV. It was found that although the rhythm of read speech of the Singaporean speakers was syllable-based as described by previous studies, the rhythm of the Malaysian speakers was even more syllable-based. Analysis of the syllables in specific utterances showed that Malaysian speakers did not reduce vowels as much as Singaporean speakers in cases of syllables in utterances. Results of the spontaneous speech confirmed the findings for the read speech; that is, the same rhythmic patterning was found which normally triggers vowel reductions.

Reinforcement and recovery of timber structures

Directory of Open Access Journals (Sweden)

Antonio Alves Dias

2006-02-01

Full Text Available Preservation of timber structures is a reason for constant concern because their deterioration often involves compromising the historical patrimony, besides endangering the safety of the structure, and consequently, of their users. Many are the examples of churches, residences or other constructions where this manifestation is a fact. The technique of reinforcing structurally endangered pieces with the addition of natural or synthetic fibers, is an alternative that has been researched. In the group of synthetic fibers, fiberglass, carbon and aramid ones are included. On the other hand, it has been frequent in the restoration of old buildings, especially in Europe, the employment of materials that were not available in the past, aiming to achieve structural, acoustic and aesthetic benefits. On an existing timber structure floor, a concrete slab has been carried out, with an appropriate connection system among the parts, constituting the composite timber-concrete structures. This alternative has been considered as extraordinarily viable, because it gathers a series of convenience related with the durability and it presents better mechanic performance than conventional timber structures. In this work, the state-of-the-art of the use of fibers as structural reinforcement and of the timber-concrete composite structures, is presented.

Value of timber continues to increase

The state owned company, Lesy SR (state forests) enjoys great power in the timber industry. It can influence which timber processing companies in Slovakia will be successful and which will not have easy access to the raw material. It manages half of the forests in Slovakia. It is the only seller of timber in this country. Four years ago, the former cabinet appointed banker, Karol Vins, as the director of the company. And he started making changes. He centralized the timber business and thousands of people left the company. The goal was clear -to increase quality and efficiency. The economic performance of the company improved. The company has finally managed to post a profit. Last year, the government changed and so has the director of the company The former banker was replaced by a new head from a forestry research background, Jozef Mindas. He approves of some of the changes introduced by his predecessor and plans to continue implementing them, although there also those he would like to change. The new manager is not concerned regarding the big change from research where he used to work in the past to director of a big company and rejects the allegation that he was nominated by HZDS. I was approached as an expert and I won a tender. I have never been a member of a political party, he stated. He appreciates that his predecessor managed to revitalize the company, which was assisted by the positive effect of out-sourcing. But on the other hand, during transformation forests were not divided up correctly. The division into units did not always take into account the specific requirements of forestry, i.e. some employees in forest units have too much work and some, working in another forest unit, less. We have to make sure that the workload is approximately at the same level everywhere. He is aware of the fact that Lesy SR, which controls two thirds of the timber market, effectively decides which factory will succeed and which one will not. But he adds that Lesy SR do

The Challenges of Malaysian Dry Ports Development

Directory of Open Access Journals (Sweden)

Jagan Jeevan

2015-03-01

Full Text Available This paper examines the functions and challenges of dry ports development in Malaysia through 11 face-to-face interviews with dry port stakeholders. The findings reveal that Malaysian dry ports are developed to accelerate national and international business, to activate intermodalism in the nation, to promote regional economic development and to enhance seaport competitiveness. Malaysian dry ports perform the function of transport and logistics, information processing, seaports and value-added services. Challenges facing Malaysian dry ports include insufficient railway tracks, unorganized container planning on the rail deck, highly dependent on single mode of transportation, poor recognition from the seaport community, and competition from localized seaports. This paper further indicates strategies for coping with these challenges and identifies future opportunities for Malaysian dry ports development.

Catastrophic shocks to existing stocks of a renewable resource can cause long-run price shifts. With timber, these long-run price shifts may be accompanied by a short-run price drop due to salvage. Hurricane Hugo damaged 20% of southern pine timber in the South Carolina Coastal Plain in 1989. To estimate the short- and long-run effects of the hurricane on the prices of timber stocks, we estimated an intervention model of the residuals of cointegration of South Carolina sawtimber and pulpwood ...

On several parameters of mechanized timbering for working faces

Energy Technology Data Exchange (ETDEWEB)

Klorik' yan, S Kh

1979-08-01

Opinion is expressed that the two basic parameters characterizing mechanical timbers, the specific force in ton-forces per square meter of the supported roof surface over the working area and the one-meter length of installed timbering, do not permit selection of the optimum type of timber for a roof of the corresponding class. Experience has demonstrated that the most precise parameter is specific strength of the timber in ton-forces per meter and the determined ratio of the strength of all posts in a section to spacing of the section along the longwall. Also an operating width not exceeding 0.4 meter should serve as a criterion for using timbers on unstable hanging walls. (In Russian)

Lee, Hana N; Mostovoy, Yulia; Hsu, Tiffany Y; Chang, Amanda H; Brem, Rachel B

2013-12-09

Comparative genomic studies have reported widespread variation in levels of gene expression within and between species. Using these data to infer organism-level trait divergence has proven to be a key challenge in the field. We have used a wild Malaysian population of S. cerevisiae as a test bed in the search to predict and validate trait differences based on observations of regulatory variation. Malaysian yeast, when cultured in standard medium, activated regulatory programs that protect cells from the toxic effects of high iron. Malaysian yeast also showed a hyperactive regulatory response during culture in the presence of excess iron and had a unique growth defect in conditions of high iron. Molecular validation experiments pinpointed the iron metabolism factors AFT1, CCC1, and YAP5 as contributors to these molecular and cellular phenotypes; in genome-scale sequence analyses, a suite of iron toxicity response genes showed evidence for rapid protein evolution in Malaysian yeast. Our findings support a model in which iron metabolism has diverged in Malaysian yeast as a consequence of a change in selective pressure, with Malaysian alleles shifting the dynamic range of iron response to low-iron concentrations and weakening resistance to extreme iron toxicity. By dissecting the iron scarcity specialist behavior of Malaysian yeast, our work highlights the power of expression divergence as a signpost for biologically and evolutionarily relevant variation at the organismal level. Interpreting the phenotypic relevance of gene expression variation is one of the primary challenges of modern genomics.

Section of mechanized timbering of an installation layer

Energy Technology Data Exchange (ETDEWEB)

Gur' yev, D K; Tomashevskiy, L P; Vorotnyak, M V

1980-07-28

A section of mechanized timbering of an installation layer is suggested which includes roof timber, base with cantilever, hydrostand, safety guard which consists of a lower and upper shield, where the lower shield in the lower part has a roll whose upper part is hinged to the cantilever base, and the upper shield is hinged to the roof timber. Its lower part is connected by a linkage to the cantilever of the base. There is also a correcting device, tie rod and holder with rolled material. In order to guarantee stability of the timbering section during work on thick beds and adaptability of the roof timber to the roofing of the bed, the connection between the cantilever and the lower part of the upper shield is made from a longitudinal slit on the cantilever and slide bar placed in it. It is attached by a pin to the lower part of the upper shield. In this case the tie bar is hinged to the linkage and by means of the slide bar to the roof timber, while the correcting device is made of an extension-type support with level which contacts with the wedge and the tightening element installed on the cantilever of the base.

The Level of Utilization of Secondary Timber Species among Furniture Producers

Directory of Open Access Journals (Sweden)

Charles Antwi-Boasiako

2016-06-01

Full Text Available Background and Purpose: Inadequate supply of wood raw material is one of the major obstacles for the global furniture industry’s growth. Several secondary timbers/Lesser-Utilized-Species (LUS that could substitute the scarce traditional timbers for furniture production exist in tropical forests. However, the industry continuously faces persistent timber shortages. The extent to which manufacturers utilize LUS as alternatives is unclear, which this study sought to ascertain. Materials and Methods: Data were collected from 300 Timber Firms from Ghana primarily through questionnaires using the stratified random sampling technique. Results: Continuous decline and non-availability of preferred traditional timbers and competition from imported furniture were the main challenges confronting the furniture industry. Data obtained indicated that most manufacturers (85% hardly use any LUS; 44% of these mentioned lack of information on their properties and prospective uses and 32% attributed it to non-availability on the domestic timber markets. However, 22% of these producers rely on traditionally ‘well-known’ timbers (e.g. mixed red wood, Guarea cedrata and Tectona grandis owing to their strength properties, 20% due to their strength and durability and 14% because of their strength and aesthetic properties. Many LUS (with prospects for furniture-making available in great quantities in many tropical forests could substitute the over-dependent timbers. However, information on their properties and uses are hardly available to local producers, which affects their popularity among timber suppliers and manufacturers. Conclusion: To improve on the level of utilization of secondary timbers, wood workers must be supplied with comprehensive information about their properties and economic values. This will contribute to reducing pressure on the primary timbers, ensuring consistent supply of timber and keeping the sector operational.

Khoo, L S; Hasmi, A H; Abdul Ghani Aziz, S A; Ibrahim, M A; Mahmood, M S

2016-04-01

A disaster is a natural or man-made (or technological) hazard resulting in an event of substantial extent causing significant physical damage or destruction, loss of life, or drastic change to the environment. It is a phenomenon that can cause damage to life and property and destroy the economic, social and cultural life of the people; and overwhelms the capacity of the community to cope with the event. The recent tragic aviation accidents in 2014 involving Malaysia Airlines flights MH370 and MH17 shocked the world in an unprecedented manner. This paper focuses on the Malaysian experience in the MH17 mission in Ukraine as well as the first ever international Disaster Victim Identification (DVI) operation for the Malaysian DVI team. The DVI operations in Hilversum, the Netherlands were well described in stages. The Netherlands' Landelijk Team Forensische Opsporing as the lead DVI team in Hilversum operated systematically, ensuring the success of the whole mission. This paper discusses the lessons learned by the Malaysian team on proper DVI structure, inter- and intra-agency cooperation, facilities planning and set up, logistics and health and safety aspects, as well as effective communication and collaboration with other international delegates. Several issues and challenges faced by the Malaysian team were also documented. In addition, the authors shared views, opinions and recommendations for a more comprehensive DVI operation in the future.

Case Studies on Timber Defects of Selected Traditional Houses in Malacca

Directory of Open Access Journals (Sweden)

Nor Haniza Ishak

2007-12-01

Full Text Available The effect of adverse environmental conditions on building materials and the extent of damage caused depends on both the materials used and the environmental conditions. Although timber is a diminishing resource, it is still widely used in today's construction. In Malaysia, timber is one of the main components of many historic buildings. Appropriate maintenance of such buildings requires an understanding of timber defects and its related problems. Timber defects are classified into two major groups: non-biological and biological deteriorations. Non-biological deterioration consists of physical decay, excessive moisture content, dimensional instability and chemical deterioration. These defects are mainly caused by the timber in service being subjected to environmental exposure. The most common and destructive timber biological deteriorations are those due to dry rot, we t rot as well as insect attacks . A study based on seven selected houses was conducted to identify the most common building defects, specifically on timber components amongst traditional Malay houses in Malacca, Malaysia, A building condition survey was carried out to determine the effect of the environment towards timber buildings and their main components. Data collected were based on the investigation and visual observation of the selected case studies. Findings of this research will serve as an indicator towards maintaining the buildings' timber components in good condition in order that the buildings' life span could be extended and primarily to conserve the valuable traditional timber houses in a historical city.

Durability of timber silencers at Wairakei geothermal steam field

Energy Technology Data Exchange (ETDEWEB)

Hedley, M E

1979-02-01

After early failures of reinforced concrete silencers and because of high costs of concrete-lined steel structures, preliminary tests were undertaken to assess the suitability of timber for silencer construction. Tests indicated that radiata pine treated with pentachlorophenol/oil or untreated red beech had most potential for timber silencer fabrication. One prototype silencer of each material was constructed and both were installed on operational bores in 1965. The red beech silencer had a service life of 4 years. The radiata pine silencer operated for 12/sup 1///sub 2/ years, although replacement had been recommended 1 year before this time expired. The performance of this silencer encouraged the general use of timber for silencer construction and further units were built. Procurement of satisfactory grades of timber has proved difficult and has limited silencer fabrication. Ways of improving timber supply, which require modification of silencer design, are discussed.

Procurement of timber for the Finnish forest industries

International Nuclear Information System (INIS)

Hakkila, P.

1995-01-01

The procurement of timber to the forest industries in the Nordic countries is based on the log-length or shortwood system, and employs load-carrying forwarders and chainsaw of single-grip harvesters. This technology is characterized by high productivity, safety, suitability for small-sized trees, high recovery of timber, and environmental friendliness. About one fourth of the industrial timber in the whole world is harvested using the log-length system. The challenge of ecological sustainability, multiple use of forests, adoption of thinnings as a tool of management, trend toward improved utilization of forest biomass, and shift from natural forests to plantations all increase the global interest in the log-length system. The paper presents a review of the Finnish forest sector, the technology of timber harvesting and transport, productivity of logging work, and costs of timber at the mill. The highly mechanized logging systems of the forest industries and the lighter technology of self-employed forest owners are discussed separately. Furthermore, the use of residual biomass as a source of clean and renewable energy, the Finnish logging machine industry, and forest operations research in Finland are also reviewed.

Historic day for Malaysian consumers.

Science.gov (United States)

Kaur, S R

1993-04-01

The Malaysian Medical Association, the Malaysian Dental Association, the Malaysian Pharmaceutical Society, and the Federation of Malaysian Consumer Associations have introduced and endorsed the Charter for Patient Rights. The Charter recognized that health care is a basic human right, regardless of race, religion, social status, and ability to pay. Further, consumers have the right to seek medical care in both the public and private sectors. The Charter also includes the right to a second opinion, one's own medical records, and explanation before receiving any medical treatment and concerning the risks of treatment, compensation for negligence, and adequate information. Malaysia is the second Asian country to have such a charter, South Korea being the first. The UK also has a Patients Charter. The rest of Europe is also moving to adopt such a charter. The private sector, which serves only those who can afford them, provides most health care services in developing countries. Thus, a large private sector threatens the elderly, unemployed, rural poor, and the mentally ill in these countries. The supply of these services is a marketable commodity which physicians and health care professionals own and sell. The medical community has planned, formulated, implemented, and monitored health services in most of these countries. Therefore, the private sector is a major obstacle to health for all. The Charter helps to break down the barrier by informing both physicians and their patients of their rights and responsibilities.

Repositioning Strategy for Malaysian Companies Internationalization

Directory of Open Access Journals (Sweden)

Ismi Rajiani

2013-04-01

Full Text Available The rise of the emerging-market countries offers both developing and developed countries a unique opportunity to gain the benefits of a truly international economy. Consequently, it is imper- ative to advance our knowledge of emerging-market countries MNC emergence and competitive- ness including Malaysian firms on how will they position their products strategically. Based on the framework of Porter’s Generic Strategy, this paper is composed of price/ volume segments and im- pacts on product strategy theory. The aim is to identify crucial triggering cues and focus areas for Malaysian companies and measure what role these play in different segments. This study argues that some Malaysian companies will reposition themselves strategically when internationalizing and that they will focus on other factors or triggering cues when doing so not merely adapting the prevalent price leadership strategy.

John Dalsgaard Sørensen, Staffan Svensson, Birgitte Dela Stang : Reliability-Based Calibration of Load Duration Factors for Timber Structures     Abstract :   The load bearing capacity of timber structures decrease with time depending on the type of load and timber. Based on representative limit...... states and stochastic models for timber structures, load duration factors are calibrated using probabilistic methods. Load duration e.ects are estimated on basis of simulation of realizations of wind, snow and imposed loads in accordance with the load models in the Danish structural codes. Three damage...... accumulation models are considered, namely Gerhards model, Barrett and Foschi _ s model and Foschi and Yao _ s model. The parameters in these models are .tted by the Maximum Likelihood Method using data relevant for Danish structural timber and the statistical uncertainty is quanti .ed. The reliability...

Finite element analysis of composite concrete-timber beams

Directory of Open Access Journals (Sweden)

N. C. S. FORTI

Full Text Available AbstractIn the search for sustainable construction, timber construction is gaining in popularity around the world. Sustainably harvested wood stores carbon dioxide, while reforestation absorbs yet more CO2. One technique involves the combination of a concrete slab and a timber beam, where the two materials are assembled by the use of flexible connectors. Composite structures provide reduced costs, environmental benefits, a better acoustic performance, when compared to timber structures, and maintain structural safety. Composite structures combine materials with different mechanical properties. Their mechanical performance depends on the efficiency of the connection, which is designed to transmit shear longitudinal forces between the two materials and to prevent vertical detachment. This study contributes with the implementation of a finite element formulation for stress and displacement determination of composite concrete-timber beams. The deduced stiffness matrix and load vector are presented along to numerical examples. Numerical examples are compared to the analytical equations available in Eurocode 5 and to experimental data found in the literature.

Facial measurements serve as a valuable tool in the treatment planning of maxillofacial rehabilitation, orthodontic treatment, and orthognathic surgeries. The esthetic guidelines of face are still based on neoclassical canons, which were used in the ancient art. These canons are considered to be highly subjective, and there is ample evidence in the literature, which raises such questions as whether or not these canons can be applied for the modern population. This study was carried out to analyze the facial features of Indian and Malaysian women by using three-dimensional (3D) scanner and thus determine the prevalence of neoclassical facial esthetic canons in both the groups. The study was carried out on 60 women in the age range of 18-25 years, out of whom 30 were Indian and 30 Malaysian. As many as 16 facial measurements were taken by using a noncontact 3D scanner. Unpaired t-test was used for comparison of facial measurements between Indian and Malaysian females. Two-tailed Fisher exact test was used to determine the prevalence of neoclassical canons. Orbital Canon was prevalent in 80% of Malaysian women; the same was found only in 16% of Indian women (P = 0.00013). About 43% of Malaysian women exhibited orbitonasal canon (P = 0.0470) whereas nasoaural canon was prevalent in 73% of Malaysian and 33% of Indian women (P = 0.0068). Orbital, orbitonasal, and nasoaural canon were more prevalent in Malaysian women. Facial profile canon, nasooral, and nasofacial canons were not seen in either group. Though some canons provide guidelines in esthetic analyses of face, complete reliance on these canons is not justifiable.

Ellegaard, Peter

2006-01-01

The focus of this paper is to describe the idea and the theory behind a finite-element model developed for analysis of timber trusses with punched metal plate fasteners (nail plates). The finite-element model includes the semirigid and nonlinear behavior of the joints (nonlinear nail and plate...... elements) and contact between timber beams, if any (bilinear contact elements). The timber beams have linear-elastic properties. The section forces needed for design of the joints are given directly by the finite-element model, since special elements are used to model the nail groups and the nail plate...... the behavior of the joints very well at lower load levels. At higher load levels the stiffness is overestimated due to development of cracks in the timber and the linear-elastic timber properties in the finite-element model....

Full Text Available This paper presents the results of an analysis of influence of the “light” steaming process on conventional drying and colour of beech timber. A stack consisting of steamed and unsteamed boards was dried. Moisture content and moisture content profiles were recorded, and at the end of drying final moisture content, moisture content difference across thickness, case-hardening and colour were determinated. No statistically significant difference between steamed and unsteamed timber was established in any of the examined parameters (MC, ΔMC, gap. The results indicate that equal (or even better drying quality can be expected with steamed beech timber than with unsteamed timber, given the same drying schedule. Dry steamed timber was darker and more reddish than the unsteamed one. An imprecision of measurement by probes in the kiln was noticed in measuring steamed and unsteamed beech timber having a moisture content of between 7% and 15%, and a solution for overcoming this problem was given.

2016-01-01

Design of joints in timber structures is crucial to reach both elegant and structural efficient designs. Design of joints should therefore be an integral part of the conceptual design phase. Traditionally this is not the case, and joints are often solely designed and analysed in the engineering...... but also increase timbers competitiveness in the building industry. The paper is part of an ongoing research project aiming at providing tools for an integrated design process for timber structures. The focus of the paper is to identify how structure and its joints contributes to architecture and vice...... design phase.

Fictionalized History: Signifying Changes to the Malaysian Nation and Identity

Directory of Open Access Journals (Sweden)

Sim Chee Cheang

2016-04-01

Full Text Available As one of the cornerstones of fiction, writers often use and confront history in their claim to “reality” and “identity” in their writing. Linda Hutcheon’s claim for “a postmodern concern for the multiplicity and dispersion of truth(s; truth(s relative to the specificity of place and culture” (1988, p. 108 is relevant to the use of history in recent Malaysian literature. The multiple and varied claims of truth(s as reflected through the fictionalizing of Malaysian history is the focus of the analysis in this article, which aims to expose the social, economic, and political implications of the Malaysian identity. The analysis of three current works of fictionalized Malaysian history from the different fictional genres of comic series, children’s history, and occidental history, represents a cross section of genres that challenge the supremacy of history’s ontological claim over identity. The deliberate contestation of received Malaysian history in fictional modes acknowledges the peripheral identity structures of race, religion, and economics that are sensitive in a multiracial country such as Malaysia.

Exploratory Assessment of a Company’s Due Diligence System against the EU Timber Regulation: A Case Study from Northwestern Russia

Directory of Open Access Journals (Sweden)

Maxim Trishkin

2015-04-01

Full Text Available This study uses a company’s due diligence system (DDS as an operational tool to ensure the origin of wood coming from northwestern Russia. The company exports a majority of its wood products to European Union (EU countries, and its DDS consists of a statement of origin, geographical information, and field verification audits. Its DDS is assessed against the European Union Timber Regulation (EUTR. Enforcement of the EUTR began in March 2013 and is compulsory for all companies importing wood-based material from outside the EU. The DDS must contain three key components: access to information on operator’s supply of timber or timber products placed on the market, a risk assessment, and a risk mitigation method. The workflow of the conformity assessment must include a literature review, statistical and field data collection, and further analysis of the requirements. Although enforcement of the EUTR began almost two years ago, there is little research on its implementation. This DDS system showed high functionality of its existing components corresponding with the general requirements of the standards developed by the Nature Ecology and People Consult (NepCon, a non-profit organization recognized as the monitoring organization by the European Commission. This wood origin system also meets the requirements of the Forest Stewardship Council (FSC certification system, while maintaining full harmonization with the EUTR legislation. However, major obstacles persist in implementation of legislation by EU member states, in terms of interpretation of requirements, prosecutions and fines, and the role of third-party evidence.

Historic timber skeleton structures and the local seismic culture

Science.gov (United States)

Bostenaru, M.

2009-04-01

This presentation deals with the employment of timber skeleton structure and the local seismic culture. After the 1755 earthquake in the reconstruction of Lisbon a type of building with timber skeleton and masonry infill called "gaiola pombalina" was promoted, since this was designed to better resists earthquakes. "Gaiola" means cage, and it was also named after the Marques de Pombal who introduced it in the reconstruction following the earthquake. The „gaiola pombalina" presents a timber skeleton with Saint Andrew crosses in the interior walls with masonry infill and thick masonry load bearing walls loosing in thickness to the upper floors in the exterior walls. The masonry can fall out during earthquakes but the building remains staying given the interior timber skeleton. The type of buildings with timber structure and (masonry) infill behaved well in earthquakes in various parts of the earth, like Nepal (the dhaji dewary type), Pakistan, Turkey (the himiş type after the 1999 earthquake) [both latter types were researched by Langenbach, www.conservationtech.com and www.traditional-is-modern.net] and also in Germany after the 1356 earthquake (the Southern German subtype of Fachwerk). Also in Italy a subtype called "casa baraccata" was promoted in a construction code to a similar time (following the 1783 earthquake in Southern Italy, see Tobriner 1983) as that of the "gaiola pombalina", the time of the Baroque, when town planning acquired another status. Unlike at the "gaiola pombalina" the "casa baraccata" the timber skeleton is at the exterior walls. For this reason this type of buildings is considered to be an expression of the local seismic culture. However, this type of buildings is common also for areas where seismic risk is not an issue, like half-timbered in England and the northern subtype of Fachwerk in Northern Germany, and in some high seismic risk regions with mountains and timber resources like Romania is not spread. Given these premises the author

Supply Chain Planning for a Timber Harvesting Plus Sale Tender

Directory of Open Access Journals (Sweden)

Josef Holoubek

2015-01-01

Full Text Available Since 2010, the Czech State Forest Enterprise has been inviting timber-harvesting tenders while insisting on the forestry company purchasing the timber from the felled trees as well. To win, a tender must offer the greatest difference between the price of the timber purchased and the cost of the operations. Thus, the forest companies are now facing new problem: apart from minimizing the logging costs they are searching for a cross-cutting and mill-distribution strategy that maximizes the selling price of the harvested timber. The optimization model devised by the present paper provides support for finding an optimal timber selling strategy and, as an important contribution, include a detailed plan for cross-cutting the logs and assign them to the particular customers. We keep the support accessible via common office software and the cross-cutting and customer-assigning problem is formulated as a linear programming model for EXCEL, a particular real-world problem is solved and, using expert comparison, the model appears to provide very good results.

On calculating the pressure on cylindrical timbers of vertical shafts in clayey soils

Energy Technology Data Exchange (ETDEWEB)

Mizyumskii, V A

1979-11-01

In order to calculate the pressure built up on timbers which have been constructed to hold back freely moving soil in a clay environment, a formula is recommended which characterizes the state of clayey soil. The formula incorporates the parameters for volume information, momentary and long displacement modulus, decay factor of deformations of the after effect, viscosity factor in the starting zone of reforming. Because the timber creates a reaction pressure on the contour of the working, the radial travel of the timber is calculated and then the pressure on the timber. Correlation of the calculated pressure with the results of measurements in workings showed that the pressure of clayey soil on the timber is the result of viscous flow deformations. Disregarding these deformations, the pressures on the shaft timbering in the Yuzhno-Belozerskii deposit were calculated at 0.004 and 0.006 tons/m/sup 2/ respectively at a depth of 90 and 142 meters. After reworking the soil and setting up timbering the pressure was calculated at 2/3 of that of the highest measurements. The formula suggested is suitable for determining pressure on timbers having a large creep. (12 refs.) (In Russian)

WELFARE IMPLICATIONS OF TIMBERLAND OWNERSHIP CHANGES IN THE U.S. TIMBER MARKETS

Directory of Open Access Journals (Sweden)

Mohammad Mahfuzur Rahman

2016-07-01

Full Text Available In the last two decades, many forest product firms in the U.S. either divested their timberlands to timber investment management organizations (TIMOs and conservation organizations or converted their corporate structures from C corporations to real estate investment trusts (REITs. All landowners sold smaller timberland tracts for nonforestry uses. Reduced timber supplies from conservation organizations and timberland loss to other nonforestry uses have consequences on producer and consumer surpluses in the U.S. timber markets. Equilibrium displacement model has been employed to evaluate the welfare changes in U.S. timber markets attributed to timberland ownership changes. Net reduction of timber supply contributed to the reduction of social surplus by $43 million in 2006. Compared to the $33 billion plus U.S. timber markets, this welfare reduction was small. Overall, this article explains the shifts of economic surpluses among producers and net surplus reduction for the society attributed to timberland ownership changes in the United States.

Juan M. Pulhin

2016-07-01

Full Text Available Forest tenure reform has no doubt attained significant gains in promoting social justice and equity in the forest sector, through legal recognition of the communities’ property rights over forest lands in many developing countries. This includes the right to harvest and market trees that the communities planted. Along these lines, the Philippines’ community-based forest management (CBFM and smallholder forestry have the potential to meet the country’s wood demand and contribute to its poverty alleviation goal. Realities on the ground, however, make this lofty aspiration seems too far-fetched. Formal and informal barriers along the timber value chain restrict the growth and obstruct opportunities for community-based timber enterprises (CBTEs and smallholder forestry. Using the case of CBFM and smallholder forestry in the Visayas and Mindanao Islands in the Philippines, respectively, this paper examines the hurdles posed by regulations and informal practices, such as restrictive policies and increased transaction costs, through a segment analysis of the timber value chain. It argues that failure to address these barriers would lead to the decline of CBTEs and smallholder enterprises, thus undermining the merits of the forest tenure reform.

Total Weight and Axle Loads of Truck Units in the Transport of Timber Depending on the Timber Cargo

Directory of Open Access Journals (Sweden)

Grzegorz Trzciński

2018-03-01

Full Text Available When transporting timber, the high variability of species, assortments and moisture content of the wood raw material does not allow the weight of the transported timber to be precisely determined. This often contributes to the excessive weight loading of the entire truck unit. The aim of the research is to present the variability of the total weight of truck units with wood cargoes (GVW—gross vehicle weight depending on the weight of the empty unit and the transported timber load, as well as to analyze the changes in GVW, unit loads of wood and load on individual truck unit axles depending on the season. This study analyzes the total weight of truck units for 376 transports of Scots pine timber at different times of the year. The total weight of the truck units depends on the weight of an empty unit and the weight of the load. GVW was determined by using a weighbridge to weigh the vehicles and then the empty unit after unloading. The weight of the load was obtained as the difference between GVW and the tare. It was found that GVW differed significantly depending on the truck unit used, ranging from 43.60–58.80 Mg, often exceeding permissible limits for public roads. The individual axle loads for various truck units were also analyzed. The obtained results indicate that these loads are more equally distributed in the case of five-axle trucks compared to six-axle ones.

This study adopts a deskwork approach by examining research papers published in leading real estate journals, both international and local and papers presented in main real estate conferences from 1997 to 2010. In addition, the number of research papers published and presented were also assessed from several main real estate research journals in the US, UK, Asia/Australia and Malaysia and conferences such as American Real Estate Society (ARES, European Real Estate Society (ERES, Pacific Rim Real Estate Society (PRRES, Asian Real Estate Society (AsRES and local conference; International Real Estate Research Symposium (IRERS. The study indicates that the Malaysian real estate researchers (MRERs have made a positive contribution to the global real estate research. Nevertheless, there is still more effort needed in order to compete in the global real estate research agenda. It is anticipated that this trend will change since the Malaysian government has emphasised on improving the quality of higher learning institutions' for which research and publication will be the main agenda. The contribution from MRERs will significantly improve Malaysian universities standing in global ranking.

Temporal Decay in Timber Species Composition and Value in Amazonian Logging Concessions.

Richardson, Vanessa A; Peres, Carlos A

Throughout human history, slow-renewal biological resource populations have been predictably overexploited, often to the point of economic extinction. We assess whether and how this has occurred with timber resources in the Brazilian Amazon. The asynchronous advance of industrial-scale logging frontiers has left regional-scale forest landscapes with varying histories of logging. Initial harvests in unlogged forests can be highly selective, targeting slow-growing, high-grade, shade-tolerant hardwood species, while later harvests tend to focus on fast-growing, light-wooded, long-lived pioneer trees. Brazil accounts for 85% of all native neotropical forest roundlog production, and the State of Pará for almost half of all timber production in Brazilian Amazonia, the largest old-growth tropical timber reserve controlled by any country. Yet the degree to which timber harvests beyond the first-cut can be financially profitable or demographically sustainable remains poorly understood. Here, we use data on legally planned logging of ~17.3 million cubic meters of timber across 314 species extracted from 824 authorized harvest areas in private and community-owned forests, 446 of which reported volumetric composition data by timber species. We document patterns of timber extraction by volume, species composition, and monetary value along aging eastern Amazonian logging frontiers, which are then explained on the basis of historical and environmental variables. Generalized linear models indicate that relatively recent logging operations farthest from heavy-traffic roads are the most selective, concentrating gross revenues on few high-value species. We find no evidence that the post-logging timber species composition and total value of forest stands recovers beyond the first-cut, suggesting that the commercially most valuable timber species become predictably rare or economically extinct in old logging frontiers. In avoiding even more destructive land-use patterns, managing

Full Text Available The aim of this paper is to review the property types diversification strategy of Malaysian REITs. Previous study has found that Malaysian REITs received poor response form investors both local and international. Furthermore, the underperformance of Malaysian REITs was linked to the characteristics of REITs’ property types and REITs’ portfolio influenced its financial performance. The lack of local study on both of these determinants of influence on performance of Malaysian REITs is a research gap, which needs to be explored that can provide more insight of it. This study showed that the property types such as office space, commercial lot, industrial, hotel and specialized property type are the important determinants, which can influence the performance of REITs. The study comprised of REITs data from 2010 until 2014, and through Multiple Regression Analysis (MRA reveals there is little influence of property types diversification strategy toward Malaysian REITs’ performance. Nevertheless, by employ correlation analysis between each of the five property types with expected return and dividend yield, this study shows Malaysian REITs’ performance of dividend yield(DY has a positive correlation value with commercial lot property type and Malaysian REITs’ performance of expected return(ER have a highest positive correlation value with industrial property types. Also, this study suggests that property type diversification play a significant role in Malaysia REITs. Other determinants such as location of property, market capitalization and REITs’ quality of advisory style that might influence the diversification strategy and financial performance of Malaysian REITs.

Francesca Rinaldi

2013-12-01

Full Text Available Efforts to increase wood mobilization have highlighted the need to appraise drivers of short-run timber supply. The current study aims to shed further light on harvesting decisions of private forest owners, by investigating optimal harvesting under uncertainty, when timber revenues are invested on financial markets and uncertainty is mitigated by news releases. By distinguishing between aggregate economic risk and sector specific risks, the model studies in great detail optimal harvesting-investment decisions, with particular emphasis on the non-trivial transmission of risk on optimal harvesting, and on the way private forest owners react to news and information. The analysis of the role played by information in harvesting decisions is a novelty in forest economic theory. The presented model is highly relevant from a policy—information is a commonly used forest policy instrument—as well as a practical perspective, since the mechanism of risk transmission is at the basis of timber pricing.

Innovative Use and Characterization of Polymers for Timber-Related Construction

Full Text Available Timber gridshells have become a very popular, efficient, sustainable and beautiful structural application of timber. However, given the slender laths involved in this form of construction, there is concern over the durability of timber for this purpose, and Glass FRP (GFRP laths have been proposed as a possible substitution. This paper considers this possibility. It goes on to look at the possible use of Basalt FRP (BFRP for the same purpose, from the perspective of its creep characteristics. It is shown that the use of GFRP gridshells is a viable form of construction, and that enhanced durability characteristics of BFRP could lead to their adoption for gridshells, given that the creep characteristics of basalt fibres presented here are comparable to those of glass fibres. An altogether different form of timber construction is that of joist-and-floorboard. In the UK, there are thousands of historic buildings which use this floor construction, and a sizeable proportion of this building stock now requires upgrade, strengthening and/or stiffening to allow these buildings to be fit for purpose into the future. This paper goes on to consider the possible use of Carbon FRP (CFRP to strengthen and stiffen such timber floors. It is shown that such strengthening and stiffening is entirely feasible, offering the potential for greatly enhanced stiffness, in particular. Further, it is shown that mechanical shear connection between CFRP and timber is best conducted using perpendicular-positioned screws, rather than raked screws.

The method, developed in research collaboration between ETH Zürich, Aarhus School of Architecture and Israel Institute of Technology, entails the coupling of truss...... processes solving timber joint intersections, robotically controlling member prefabrication, and spatial robotic assembly of the optimized timber structures. The implication of this concept is studied through pilot fabrication and load-testing of a full scale prototype structure.......-based topology optimization with digital procedures for rationalization and robotic assembly of bespoke timber members, through a procedural, cross-application workflow. Through this, a direct chaining of optimization and robotic fabrication is established, in which optimization data is driving subsequent...

Compression strength perpendicular to grain of structural timber and glulam

DEFF Research Database (Denmark)

Damkilde, Lars; Hoffmeyer, Preben; Pedersen, Torben N.

1998-01-01

The characteristic strength values for compression perpendicular to grain as they appear in EN 338 (structural timber) and EN 1194 (glulam) are currently up for discussion. The present paper provides experimental results based on EN 1193 that may assist in the correct assignment of such strength...... values. The dominant failure mode of glulam specimens is shown to be fundamentally different from that of structural timber specimens. Glulam specimens often show tension perpendicular to grain failure before the compression strength value is reached. Such failure mode is not seen for structural timber....... Nonetheless test results show that the levels of characteristic compression strength perpendicular to grain are of the same order for structural timber and glulam. The values are slightly lower than those appearing in EN 1194 and less than half of those appearing in EN 338. The paper presents a numerical...

Seismic retrofitting of timber framed walls

Gonçalves, A. M.

2014-12-01

Full Text Available After the 1755 earthquake that destroyed Lisbon, an innovative anti-seismic structural system was developed consisting of a timber skeleton, that included timber framed masonry walls. After more than 250 years these structures need rehabilitation to face the present demands. The research presented in this paper aimed at experimentally characterizing the cyclic behaviour of timber framed walls reinforced with three different methods, namely: (i elastic-plastic dampers on diagonal braces, (ii reinforcement of timber connections with steel plates, (iii application of a reinforced rendering. The elastic-plastic damper showed an unsymmetrical behaviour and some difficulties to implement in practice. The strengthening with reinforced render led to an initial stiffness increase but showed a limited deformation capacity. The walls with reinforcing steel plates at the timber connections showed the best behaviour in terms of strength, stiffness and energy dissipation.Después del terremoto de 1755 que destruyó Lisboa, un sistema estructural antisísmico muy innovador fue desarrollado. El sistema consistió en un esqueleto de madera, que incluyó la construcción de muros de mampostería con un entramado de madera.

State forest timber sales in 2006

Office National des Forets

2007-01-01

For the first time since the 1999 storms, forest owners have experienced a favourable market. The combination of buoyant demand for both industrial round-wood and timber and consolidation of supply led to a significant increase in prices. With a logging volume of 15 million m 3 (standing timber equivalent), state forest timber supply has remained at a high level, slightly above that of 1999. The improved business cycle situation has pushed prices up, including for beech for which rates had stagnated for some time. However, in spite of the 15% rise compared to 2005, the average per cubic metre price sold by the ONF (31.20 euros), all categories of timber and all state forests taken together, remains well below the average for the 1996-1999 period (37.80 euros). While unsold stocks have fallen considerably, the ONF has sought to facilitate access to products by industry by modernising its sales methods in line with the new 2005 legislative and regulatory provisions. Greater flexibility in the rules applicable to privately negotiated spot sales and supply contracts should over time contribute to stabilizing and reducing the accessory costs of supply. The changes implemented over the last decade in favour of private sales, which now account for nearly 40% of volumes sold, should continue in the future. Of those volumes, 20% were sold under supply contracts, a proportion that is rising sharply. These contracts covered more than one million m 3 in 2006, encouraging the ONF to adopt a new sales scheme and establish structures for consultations with both forest municipalities and the downstream component of the industry.

A large body of epidemiological data has demonstrated that diet quality follows a sociodemographic gradient. Little is known, however, about food group intake patterns among Malaysian children. This study aimed to assess consumption pattern of 7 food groups, including cereals/grains, legumes, fruits, vegetables, fish, meat/poultry, and milk/dairy products, among children 7 to 12 years of age. A total of 1773 children who participated in SEANUTS Malaysia and who completed the Food Frequency Questionnaire were included in this study. A greater proportion of children aged 10 to 12 years have an inadequate intake of cereals/grains, meat/poultry, legumes, and milk/dairy products compared with children 7 to 9 years old. With the exception of meat/poultry, food consumption of Malaysian children did not meet Malaysian Dietary Guidelines recommendations for the other 6 food groups, irrespective of sociodemographic backgrounds. Efforts are needed to promote healthy and balanced dietary habits, particularly for foods that fall short of recommended intake level. © 2016 APJPH.

Assessing the Sustainability of EU Timber Consumption Trends: Comparing Consumption Scenarios with a Safe Operating Space Scenario for Global and EU Timber Supply

Directory of Open Access Journals (Sweden)

Meghan O’Brien

2017-12-01

Full Text Available The growing demand for wood to meet EU renewable energy targets has increasingly come under scrutiny for potentially increasing EU import dependence and inducing land use change abroad, with associated impacts on the climate and biodiversity. This article builds on research accounting for levels of primary timber consumption—e.g., toward forest footprints—and developing reference values for benchmarking sustainability—e.g., toward land use targets—in order to improve systemic monitoring of timber and forest use. Specifically, it looks at future trends to assess how current EU policy may impact forests at an EU and global scale. Future demand scenarios are based on projections derived and adapted from the literature to depict developments under different scenario assumptions. Results reveal that by 2030, EU consumption levels on a per capita basis are estimated to be increasingly disproportionate compared to the rest of the world. EU consumption scenarios based on meeting around a 40% share of the EU renewable energy targets with timber would overshoot both the EU and global reference value range for sustainable supply capacities in 2030. Overall, findings support literature pointing to an increased risk of problem shifting relating to both how much and where timber needed for meeting renewable energy targets is sourced. It is argued that a sustainable level of timber consumption should be characterized by balance between supply (what the forest can provide on a sustainable basis and demand (how much is used on a per capita basis, considering the concept of fair shares. To this end, future research should close data gaps, increase methodological robustness and address the socio-political legitimacy of the safe operating space concept towards targets in the future. A re-use of timber within the economy should be supported to increase supply options.

Three recent studies showed that taste intensity signals nutrient content. However, current data reflects only the food patterns in Western societies. No study has yet been performed in Asian culture. The Malaysian cuisine represents a mixture of Malay, Chinese and Indian foods. This study aimed to investigate the associations between taste intensity and nutrient content in commonly consumed Dutch (NL) and Malaysian (MY) foods. Perceived intensities of sweetness, sourness, bitterness, umami, saltiness and fat sensation were assessed for 469 Dutch and 423 Malaysian commonly consumed foods representing about 83% and 88% of an individual's average daily energy intake in each respective country. We used a trained Dutch (n = 15) and Malaysian panel (n = 20) with quantitative sensory Spectrum™ 100-point rating scales and reference solutions, R1 (13-point), R2 (33-point) and R3 (67-point). Dutch and Malaysian foods had relatively low mean sourness and bitterness (Malaysian foods (15-point) was higher than that of Dutch foods (8-point). Positive associations were found between sweetness and mono- and disaccharides (R 2  = 0.67 (NL), 0.38 (MY)), between umami and protein (R 2  = 0.29 (NL), 0.26 (MY)), between saltiness and sodium (R 2  = 0.48 (NL), 0.27 (MY)), and between fat sensation and fat content (R 2  = 0.56 (NL), 0.17(MY)) in Dutch and Malaysian foods (all, p < 0.001). The associations between taste intensity and nutrient content are not different between different countries, except for fat sensation-fat content. The two dimensional basic taste-nutrient space, representing the variance and associations between tastes and nutrients, is similar between Dutch and Malaysian commonly consumed foods.

Implementing CITES regulations for timber.

Science.gov (United States)

Blundell, Arthur G

2007-03-01

Foresters are currently confronted with a new challenge. For the first time a commonly traded timber species has been listed on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). At the 12th Conference of the Parties in November 2002, countries voted 68 to 30 to place the premier timber species of Latin America, big-leaf mahogany (Swietenia macrophylla King [Meliaceae]), on CITES Appendix II. Under Appendix II regulations, trade in mahogany requires that exporting countries verify that each shipment was legally obtained and that its harvest was non-detrimental to the survival of the species. Unfortunately, implementation has been weak, in part because countries have yet to develop a common, pragmatic, cost-effective system to make the legal and non-detriment findings. This paper recommends what such a system might include.

In general these characteristics can have a positive influence on system reliability of a structure however, in Eurocodes ductility is only awarded for concrete and steel structures but not for timber structures. It is well......-know that structural systems can redistribute internal forces due to ductility of a connection, i.e. some additional loads can be carried by the structure. The same effect is also possible for reinforced concrete structures and structures of steel. However, for timber structures codes do not award that ductility......For reduction of the risk of collapse in the event of loss of structural element(s), a structural engineer may take necessary steps to design a collapse-resistant structure that is insensitive to accidental circumstances e.g. by incorporating characteristics like redundancy, ties, ductility, key...

Protection of mechanized timberings on beds dangerous for mine impacts

Energy Technology Data Exchange (ETDEWEB)

Budirsky, S

1982-01-01

In some stoping faces on beds which are dangerous for mine impacts, mechanized timbering is successfully used which is not equipped with protection from the effect of these dynamic phenomena. This generated the idea that in the indicated conditions, mechanized timbering may not be equipped with protective devices against dynamic loads. Theoretical studies have shown that the effects of mine impacts depends on the total energy of the impact, distance of this stoping face from the epicenter of the impact, as well as the capacity of the rock massif to transmit and absorb energy of the mine impact. This means that the effect of the mine impact under different conditions is not the same, the mine impacts of lower energy under definite conditions can result in greater damages to the mechanized timbering than mine impact with higher energy. It is believed that the effect of absorption of energy of the mine impact depends on the method of control of the roofing in the stoping face, the presence of hydraulic fill quarantees absorption of up to 80% of its energy. The experience of working beds which are dangerous for mine impacts in the upper Silesia coal basin indicated that the designs of the mechanized timbering, especially shield, in which the stands are not rigidly connected to the roof timber, during operation on beds with thickness 2.5-4 m withstand mine impacts with energy 10/sup 7/ J without significant disorders (mine impacts with this energy occur very frequently . For energy of mine impact of 108 J (impacts with this energy are observed comparatively rarely), the mechanized timberings are considerably damaged.

The Work-Related Quality of Life Scale-2 (WRQLS-2) has been used to measure quality of working life (QOWL) in the United Kingdom. In this study, the scale was translated and normalized into Malay. The scale was translated using the back-translation method, pretesting, and pilot testing. It was conducted among health care and office workers. It was tested in 3 stages; confirmatory factor analysis at stages 1 and 3 and exploratory factor analysis at stage 2. The Malaysian WRQLS-2 had 5 factors: "General Well-Being," "Job and Career Satisfaction," "Employee Engagement," "Home-Work Interface," and "Stress at Work." The scale showed good convergent and construct validity and also reliability. Perception of good QOWL may differ because of cultural influences and varying work environments. The validated Malaysian WRQLS-2 can be used to determine the QOWL of Malaysian office and health care workers. © 2015 APJPH.

Traditional Postpartum Practices Among Malaysian Mothers: A Review.

Science.gov (United States)

Fadzil, Fariza; Shamsuddin, Khadijah; Wan Puteh, Sharifa Ezat

2016-07-01

To briefly describe the postpartum practices among the three major ethnic groups in Malaysia and to identify commonalities in their traditional postpartum beliefs and practices. This narrative review collated information on traditional postpartum practices among Malaysian mothers through a literature search for published research papers on traditional postpartum practices in Malaysia. This review shows that Malaysian mothers have certain postpartum practices that they considered to be important for preventing future ill health. Despite the perceived differences in intra-ethnic postpartum practices, most Malaysian mothers, although from different ethnicities, share similarities in their postpartum regimens and practices in terms of beliefs and adherence to food taboos, use of traditional postpartum massage and traditional herbs, and acknowledgment of the role of older female family members in postpartum care. Health care providers should be aware of multiethnic traditional postpartum practices and use the commonalities in these practices as part of their postpartum care regimen.

Malaysian government’s aim to include nuclear energy for electricity generation has triggered various reactions from all especially the public. The objective of this study is to have a better understanding on the knowledge, sources of information of nuclear power and sources of energy chosen by Malaysian in 20 years’ time. Besides that, we want to examine the level of acceptance and perception of Malaysian towards nuclear energy and we want to identify the correlation between public perceptions with the acceptance towards nuclear power in Malaysia, and also to study the differences between perception and acceptance of nuclear power with gender and educational level. For this research methodology, the research questions are given orally or through paper-pencil and also social networking site such as Facebook or through electronic media application such as WhatsApp and Google docs. The data were analysed using a SPSS version 22.0 (Statistical Package for the Social Sciences). Results showed that more than 50% of the respondents have the knowledge of nuclear energy. A part of from that, only 39 % are confident government can afford to build NPP in Malaysia and 41 % disagree nuclear energy is the best option for future energy. From analysis using SPSS 22 we estimate negative perception will give a negative acceptance in term of support towards the use of nuclear energy in power generation in Malaysia. There are also slight correlation that the higher the level of education of Malaysian, the more negative the perception of Malaysian in accepting nuclear energy as source of power in Malaysia. Therefore in shaping a positive acceptance of NPP in Malaysia, the authorities need to educate the people with the knowledge of nuclear in order to overcome the negative perception towards nuclear power.

Żmijewki, Tomasz; Wojtowicz-Jankowska, Dorota

2017-10-01

The aim of this article is to present various types of wood-based products, classified as engineered timber, while specifying the implications of their structural properties for their forms. Timber is used as a construction material due to its fire resistance, good structural characteristics and insulating properties. The advent of new technologies of wood processing and wood-based materials production has converted timber into a high-tech material, thus encouraging the architects to consider it ever more often in their projects. As wooden technologies overcome constraints, timber begins to compete with steel and concrete. The design characteristics of new wood-based products allow wooden structures to be higher, have larger spans, and more diverse forms than ever. Wood-based materials include materials made of solid wood, veneers, strand, and wood which, due to its inferior quality, would otherwise be unfit for constructions. Elements and layers of these products are glued using different kinds of strong and water-resistant adhesives. The article presents the history of development of new wood technologies, discussing increasingly popular wood-based materials such as glued laminated timber, cross-laminated timber, or structural composite lumber. The paper analyses their technical and fire-resistance properties, and points to ecological aspect, as factors contributing to the growing popularity of these materials. Finally, the timber’s characteristics are contrasted with those of steel and concrete. The article lists examples of wooden objects representing the so-called small architecture structures from across Europe. They illustrate the potential, the uniqueness and the versatility that wood-based materials offer for constructors and architects. All these features form sufficient grounds for stating that timber truly is a construction material of the 21st century.

Funded and administered by NASA, the Affiliated Research Center (ARC) program transfers geospatial technologies from the Space Agency and participating universities to commercial companies, non-profit and trade organizations, and tribal governments. The origins of the ARC program date back to 1988, when NASA's Stennis Space Center initiated the Visiting Investigator Program to bring industry closer to spatial information technologies. The success of this trial program led to an expansion into the ARC program, whose goal is to enhance competitiveness of U.S. industries through more efficient use of remote sensing and related technologies. NASA's ARC program served as the foundation for the development of International Hardwood Resources, which then grew into Falcon Informatics with the acquisition of a technology from a European software company and a change of business models. Doylestown, Pennsylvania-based Falcon Informatics is now a world-leading information services company that combines in-depth timber industry experience with state-of-the-art software to serve the needs of national governments, international paper companies, and timber-investment management organizations.

The Interaction between FSC Certification and the Implementation of the EU Timber Regulation in Romania

Full Text Available This explorative study aims to shed light on the ways in which Forest Stewardship Council (FSC certification interacts with the implementation of the EU Timber Regulation (EUTR in Romania. To this end, the EUTR implementation process is examined, and the relationship between this implementation and FSC certification is explored. There is a particular focus on the extent to which certification has helped companies to comply with EUTR requirements. The study uses the analytical framework of Transnational Business Governance Interactions (TBGI and a mixed research approach. It is found that FSC certification has to a large extent helped companies to prepare for and align with the EUTR’s requirements, in particular concerning risk assessment and risk mitigation procedures needed for a due diligence system (DDS, and in the context of a “policy vacuum” period related to EUTR implementation. Moreover, recent changes in the FSC standard make it theoretically in line with EUTR requirements. However, difficulties remain in relation to the lack of information, costs and bureaucracy associated with both EUTR implementation and FSC certification. Notably, in the absence of a monitoring organization, the establishment of a viable DDS is still problematic as many companies remain unprepared for developing their own systems. Finally, the EUTR and its risk management requirements may have partly fueled the increase in uptake of chain of custody (CoC certification in Romania. However, due to the risk of CoC certificates including illegally sourced timber, this recent uptake in certification does not necessarily indicate improved sustainable forest management (SFM or full compliance with EUTR.

Malaysian nurses' evaluation of transnational higher education courses.

Science.gov (United States)

Arunasalam, Nirmala

The internationalisation of higher education has led some UK and Australian universities to deliver transnational higher education (TNHE) post-registration top-up nursing degree courses in Malaysia. These are bridging courses that allow registered nurses to upgrade their diploma qualifications to degree level. What is not sufficiently explored in the literature is nurses' evaluation of these courses and the impact of TNHE qualifications. A hermeneutic phenomenology approach was used to explore the views of 18 Malaysian nurses from one Australian and two UK TNHE universities. Semi-structured interviews were conducted to enable the Malaysian nurses to evaluate the courses. Data were analysed by thematic analysis. Findings showed a gap between Malaysian and Western teaching and learning outlook, professional values and clinical practices. The data give important insights at a time when the aim of Malaysia's investment in TNHE courses is to attain a graduate workforce with changed mindsets and enhanced patient care.

FACTORS INFLUENCING YIELD SPREADS OF THE MALAYSIAN BONDS

Norliza Ahmad

2009-01-01

Full Text Available Malaysian bond market is developing rapidly but not much is understood in terms of macroeconomic factors that could influence the yield spread of the Ringgit Malaysian denominated bonds. Based on a multifactor model, this paper examines the impact of four macroeconomic factors namely: Kuala Lumpur Composite Index (KLCI, Industry Production Index (IPI, Consumer Price Index (CPI and interest rates (IR on bond yield spread of the Malaysian Government Securities (MGS and Corporate Bonds (CBs for a period from January 2001 to December 2008. The findings support the expected hypotheses that CPI and IR are the major drivers that influence the changes in MGS yield spreads. However IPI and KLCI have weak and no influence on MGS yield spreads respectively Whilst IR, CPI and IPI have significant influence on the yield spreads of CB1, CB2 and CB3, KLCI has significant influence only on the CB1 yield spread but not on CB2 and CB3 yield spreads.

Full Text Available The success of Malaysian construction companies creates an opportunity to explore abroad. Past studies have shown that the difficulty of expatriates in adjusting to a new environment is the main aspect that leads to failure of assignments. The success in implementing an overseas assignment does not solely depend on an expatriate’s technical expertise. The adjustment issues such as the interaction with the host nationals, and adaptability to the host country’s culture also exert influence on the assignment. The research was conducted to identify the influence of executive expatriate general adjustment on assignment in host countries. The objective of the study was to identify adjustment influence factors relating to general adjustment abroad. Questionnaires were sent to Malaysian expatriate executives. Sixty four Malaysian expatriate executives from Malaysian construction companies overseas were involved in this study. The findings show interaction, social and living environment influences their adjustment during expatriation. Pre-departure training preparation aspects for expatriates is a good step before their departure to host countries.

A Feasibility Study on Timber Damage Detection Using Piezoceramic-Transducer-Enabled Active Sensing

Directory of Open Access Journals (Sweden)

Jicheng Zhang

2018-05-01

Full Text Available In recent years, piezoelectric-based transducers and technologies have made significant progress towards structural health monitoring and damage evaluation for various metal and concrete structures. Timber is still commonly used as a construction material in practical engineering; however, there is a lack of research on the health monitoring of timber-based structures using piezoelectric-based transducers and methods. This paper conducts a feasibility study on timber damage detection using surface-mounted piezoelectric patches, which enable the stress-wave-based active sensing approach. Typical damage modes in timber frame structures, such as surface cracks and holes, were investigated in this study. In the active sensing approach, one piezoceramic transducer is used as an actuator to generate stress waves, which propagate along the surface of the timber structure, and other piezoceramic transducers function as sensors to detect the propagating stress waves. Defects, such as a crack or a hole, induce additional attenuation to the propagating stress wave. Based on this attenuation, the proposed method can detect the defects using the wavelet-packet-based damage index, demonstrating its implementation potential for real-time timber damage detection.

Agroforestry systems of timber species and cacao: survival and growth during the early stages

Directory of Open Access Journals (Sweden)

Wilmer Espinoza

2013-08-01

Full Text Available In recent times, increased emphasis has been placed on diversifying the types of trees to shade cacao (Theobromacacao L. and to achieve additional services. Agroforestry systems that include profitable and native timber trees are a viable alternative but it is necessary to understand the growth characteristics of these species under different environmental conditions. Thus, timber tree species selection should be based on plant responses to biotic and abiotic factors. The aims of this study were (1 to evaluate growth rates and leaf area indices of the four commercial timber species: Cordia thaisiana, Cedrela odorata, Swietenia macrophylla and Tabebuia rosea in conjunction with incidence of insect attacks and (2 to compare growth rates of four Venezuelan Criollo cacao cultivars planted under the shade of these four timber species during the first 36 months after establishment. Parameters monitored in timber trees were: survival rates, growth rates expressed as height and diameter at breast height and leaf area index. In the four Cacao cultivars: height and basal diameter. C. thaisiana and C. odorata had the fastest growth and the highest survival rates. Growth rates of timber trees will depend on their susceptibility to insect attacks as well as to total leaf area. All cacao cultivars showed higher growth rates under the shade of C. odorata. Growth rates of timber trees and cacao cultivars suggest that combinations of cacao and timber trees are a feasible agroforestry strategy in Venezuela.

2011-07-01

The objective of this study was to investigate thermoregulatory responses to heat in tropical (Malaysian) and temperate (Japanese) natives, during 60 min of passive heating. Ten Japanese (mean ages: 20.8 ± 0.9 years) and ten Malaysian males (mean ages: 22.3 ± 1.6 years) with matched morphological characteristics and physical fitness participated in this study. Passive heating was induced through leg immersion in hot water (42°C) for 60 min under conditions of 28°C air temperature and 50% RH. Local sweat rate on the forehead and thigh were significantly lower in Malaysians during leg immersion, but no significant differences in total sweat rate were observed between Malaysians (86.3 ± 11.8 g m-2 h-1) and Japanese (83.2 ± 6.4 g m-2 h-1) after leg immersion. In addition, Malaysians displayed a smaller rise in rectal temperature (0.3 ± 0.1°C) than Japanese (0.7 ± 0.1°C) during leg immersion, with a greater increase in hand skin temperature. Skin blood flow was significantly lower on the forehead and forearm in Malaysians during leg immersion. No significant different in mean skin temperature during leg immersion was observed between the two groups. These findings indicated that regional differences in body sweating distribution might exist between Malaysians and Japanese during heat exposure, with more uniform distribution of local sweat rate over the whole body among tropical Malaysians. Altogether, Malaysians appear to display enhanced efficiency of thermal sweating and thermoregulatory responses in dissipating heat loss during heat loading. Thermoregulatory differences between tropical and temperate natives in this study can be interpreted as a result of heat adaptations to physiological function.

Global timber trade pattern: the cards have changed

OpenAIRE

Roda Jean-Marc; Rohana Abd Rahman; Ismariah Ahmad; Lim Hin Fui; Mohd Parid Mamat

2011-01-01

Since the 1960s, the global timber trade has gradually evolved from a South-North trade to a South-South trade, with an acceleration of the phenomenon in the mid 1990s. Nowadays, Asia consumes more than 70% (in round wood equivalent) of the forest products originating from the tropics. Africa becomes the new frontier for the supplies of wood material for Asian giants, which now source raw wood from all over the world. Since the mid 1990s, the dynamics of the tropical timber trade have been in...

Can Structural Timber Foster Short Procurement Chains within Mediterranean Forests? A Research Case in Sardinia

Directory of Open Access Journals (Sweden)

Massimo Fragiacomo

2015-06-01

Full Text Available Background and Purpose: The aim of this paper is to present the idea of a timber short procurement chain as a means to provide an increased value to Mediterranean forests. It is based on the evidence that timber buildings are increasingly used for a number of reasons including sustainability, the speed of erection, and excellent structural and seismic performance. However, most of the timber currently used around the Mediterranean is imported from outside this area. Materials and Methods: The idea is to use the best part of the tree to produce timber boards, while all the remaining part of the tree including the production waste is used for energy production. Important issues to address are the generally low mechanical properties of locally-grown timber such as maritime pine in Sardinia, which would make some wood-based products such as glue-laminated timber not technically viable. Cross-laminated timber panels are a possible solution to this problem because this wood-based product is manufactured in such a way that even with low-quality timber boards it is possible to obtain a medium quality panel. The panel is made of layers of timber boards with the adjacent layers glued under pressure at a right angle. Another issue is the need to grade the local timber, for which a number of specimens must be tested to destruction in order to identify a visual or a machine-stress grading procedure. Last but not least, the panels must be tested to destruction to correlate their mechanical properties to the properties of the boards. Results: The preliminary mechanical tests carried out on Sardinia maritime pine confirm that the material is low-grade because it is characterized by large knots and a significant grain deviation. Nevertheless, when used in the cross-laminated panels, the properties are significantly improved due to the layout of the panel which reduces the influence of defects in the boards on the mechanical properties of the panel.

Radiation technique in density and strength testing of coniferous structural timber

International Nuclear Information System (INIS)

Dzbenski, W.; Krzosek, S.

1998-01-01

The control process of intermediate and final wood products manufacturing is more and more frequently assisted by flow detectors. In radiation devices cesium isotope 137 Cs is replaced by less harmful americium 241 Am. Americium 241 Am was used in the measuring device made in The Academy of Mining and Metallurgy in Cracow. The device was applied in Warsaw Agricultural University (SGGW) in research on Polish structural timber. Negative influence of anatomical defects (knots, compression wood, resinasis, slope of grain, decay) was estimated by gammascopy method. Botanical species (pine, spruce), position in a stem (sapwood, heartwood), anatomical direction (radial, tangential) and moisture content were taken into account. The method of determination a critical place in timber were density is the lowest value (what is an obligatory criterion of stress graded structural timber according to EN standards) was developed. The practical implementation of the method can be reached when sawmills producing structural timber (especially for export) will be more interested in using miniaturized isotope densitometers.

The influence of socioeconomic status (ethnicity, income and parity) on electrolyte composition (sodium and potassium) in human milk is little known. We have thus quantitatively analyzed approximately 700 samples of milk (1-90 days postpartum) obtained from healthy Malaysian mothers' (Malay, Chinese and Indians) of full term infants. Results show that the mean concentration (mmol/l) of sodium is highest (48.2+or-1.7, Mean+or-SEM) in the Malaysian mothers' colostrum and this value decreased by 30% in their transitional milk and remained constant throughout subsequent days of lactation (mature milk). Ethnically, it is found that the level of sodium in colostrum of Malay and Chinese mothers were similar while the Indian mothers' colostrum showed apparently higher value (52.7+or-3.4 mmol/l) that is statistically insignificant. The transitional milk of all 3 ethnic groups studied exhibited similar levels of sodium. On subsequent days of lactation (mature milk) the Malay mothers exhibited lowest concentration (25.9+or-2.6 mmol/l) of sodium that is significantly (P0.05) different from that of Chinese and Indian mothers. Income and parity do not significantly affect the sodium level in Malaysian mothers' milk during all stages of lactation studied. The level of potassium, however did not change significantly with days of lactation. Like sodium, potassium too was not influenced by income and parity. (Author's).

Growth references are useful for the screening, assessment and monitoring of individual children as well as for evaluating various growth promoting interventions that could possibly affect a child in early life. To determine the growth centiles of Malaysian children and to establish contemporary cross-sectional growth reference charts for height and weight from birth to 6 years of age based on a representative sample of children from Malaysia. Gender- and age-specific centile curves for height and weight were derived using the Cole's LMS method. Data for this study were retrieved from Malaysian government health clinics using a two-stage stratified random sampling technique. Assessment of nutritional status was done with the SD scores (Z-scores) of WHO 2006 standards. Boys were found to be taller and heavier than girls in this study. The median length of Malaysian children was higher than the WHO 2006 standards and CDC 2000 reference. The overall prevalence of stunting and underweight were 8.3% and 9.3%, respectively. This study presents the first large-scale initiative for local reference charts. The growth reference would enable the growth assessment of a Malaysian child compared to the average growth of children in the country. It is suggested that the use of WHO 2006 Child Growth Standards should be complemented with local reference charts for a more wholesome growth assessment.

Mohammed Zin Nordin; Shanthi Balraj; Nor Azilah Ngah; Irfan Naufal Umar; Kamarulazizi Ibrahim

2006-01-01

Energy is a key component in Malaysian economy and contributes to the industrialization of the economy. Energy production in Malaysia, however, is mainly based on burning fossil fuels such as oil, gas and coal, all of which emit pollutants. Improving the energy performance of the nation and reducing overall energy consumption will lead to a meaningful environment and economic progress. The first part of the paper looks at the agenda on energy efficiency (EE) while the second part of the paper examines the Malaysian public knowledge on EE based on survey information obtained from 2,444 respondents by way of questionnaires. The study notes that in general most Malaysian have very little knowledge on energy efficiency, as it is a relatively new area to the people of Malaysia. This paper argues that education and training in raising awareness on energy efficiency (EE) is critical to the Malaysian society as we cannot be complacent with the existing sources of energy derived from crude oil and gas. The findings will chart some of the challenges confronting the country in promoting the agenda on energy efficiency

Balancing Conservation and Economic Sustainability: The Future of the Amazon Timber Industry

Science.gov (United States)

Merry, Frank; Soares-Filho, Britaldo; Nepstad, Daniel; Amacher, Gregory; Rodrigues, Hermann

2009-09-01

Logging has been a much maligned feature of frontier development in the Amazon. Most discussions ignore the fact that logging can be part of a renewable, environmentally benign, and broadly equitable economic activity in these remote places. We estimate there to be some 4.5 ± 1.35 billion m3 of commercial timber volume in the Brazilian Amazon today, of which 1.2 billion m3 is currently profitable to harvest, with a total potential stumpage value of 15.4 billion. A successful forest sector in the Brazilian Amazon will integrate timber harvesting on private lands and on unprotected and unsettled government lands with timber concessions on public lands. If a legal, productive, timber industry can be established outside of protected areas, it will deliver environmental benefits in synergy with those provided by the region’s network of protected areas, the latter of which we estimate to have an opportunity cost from lost timber revenues of 2.3 billion over 30 years. Indeed, on all land accessible to harvesting, the timber industry could produce an average of more than 16 million m3 per year over a 30-year harvest cycle—entirely outside of current protected areas—providing 4.8 billion in returns to landowners and generating 1.8 billion in sawnwood sales tax revenue. This level of harvest could be profitably complemented with an additional 10% from logging concessions on National Forests. This advance, however, should be realized only through widespread adoption of reduced impact logging techniques.

Eleventh-century shift in timber procurement areas for the great houses of Chaco Canyon.

Science.gov (United States)

Guiterman, Christopher H; Swetnam, Thomas W; Dean, Jeffrey S

2016-02-02

An enduring mystery from the great houses of Chaco Canyon is the origin of more than 240,000 construction timbers. We evaluate probable timber procurement areas for seven great houses by applying tree-ring width-based sourcing to a set of 170 timbers. To our knowledge, this is the first use of tree rings to assess timber origins in the southwestern United States. We found that the Chuska and Zuni Mountains (>75 km distant) were the most likely sources, accounting for 70% of timbers. Most notably, procurement areas changed through time. Before 1020 Common Era (CE) nearly all timbers originated from the Zunis (a previously unrecognized source), but by 1060 CE the Chuskas eclipsed the Zuni area in total wood imports. This shift occurred at the onset of Chaco florescence in the 11th century, a time with substantial expansion of existing great houses and the addition of seven new great houses in the Chaco Core area. It also coincides with the proliferation of Chuskan stone tools and pottery in the archaeological record of Chaco Canyon, further underscoring the link between land use and occupation in the Chuska area and the peak of great house construction. Our findings, based on the most temporally specific and replicated evidence of Chacoan resource procurement obtained to date, corroborate the long-standing but recently challenged interpretation that large numbers of timbers were harvested and transported from distant mountain ranges to build the great houses at Chaco Canyon.

Efficiency and Competition in the Malaysian Banking Market: Foreign versus Domestic Banks

Directory of Open Access Journals (Sweden)

Rossazana Ab-Rahim

2017-08-01

Full Text Available The aim of this paper is to investigate efficiency performance of Malaysian banking market using data envelopment analysis approach in the context of the increasing presence of foreign banks. Specifically, two measures of efficiency are constructed, cost and profit efficiency by utilizing bank-level data of Malaysian commercial banks, over the period 2003 to 2014. The results obtained show the domestic banks are more efficient than the foreign banks counterparts for both measures of efficiency. Next, the Lerner Index approach is employed to measure competition and finally, Granger causality tests are undertaken to answer the question, does competition foster efficiency? The results of causality tests support a positive effect of competition on cost and profit efficiency of Malaysian banks. With regard to the financial liberalization, the findings imply that higher competitive pressure may be offset the market power of individual banks; however, eventually it will results in efficiency gains of Malaysian banks.

Successful and unsuccessful attempts to resolve caribou management and timber harvesting issues in west central Alberta

Directory of Open Access Journals (Sweden)

David Hervieux

1996-01-01

Full Text Available Research studies of woodland caribou in west central Alberta began in 1979 in response to proposed timber harvesting on their winter ranges. Using results from initial studies, timber harvest guidelines were developed. A recent review of these guidelines, and the assumptions on which they were based, has resulted in a renegotiation by government and industry of timber harvesting on caribou range in west central Alberta. Caribou range in west central Alberta overlaps many jurisdictional boundaries: federal and provincial lands, four Forest Management Agreement Areas, three Alberta Land and Forest Service Regions and two Alberta Fish and Wildlife Service Regions. This jurisdictional complexity in combination with other factors such as total allocation of the timber resources, high levels of petroleum, natural gas and coal extraction activities, a high level of concern by public groups for caribou conservation and recent understanding of woodland caribou needs for abundant space has made resolution of caribou/timber harvest conflicts exceedingly slow and often relatively unproductive. This paper reviews 10 years of trying to resolve conflicts between timber harvesting and caribou conservation through meetings, committees, integrated resource planning, policy papers and public consultation. We describe what might be learned by other jurisdictions that are trying to resolve similar caribou/timber harvesting issues. We conclude with an overview of recent timber harvest planning initiatives on caribou range in west central Alberta.

The aim of this study is to examine innovative activities in small and medium enterprises (SMEs) in the Malaysian information technology (IT) industry. This study addresses three research questions: 1. What is the innovation pattern among SMEs in the Malaysian IT industry? 2. How significant is interactive learning between SMEs in the Malaysian IT industry and other agents in the innovation system? and 3. What is the role of the government in promoting innovation among SMEs in the Malaysian IT industry? Two approaches were taken to collect data for this study, that is, mail survey and face-to-face interviews. Based on findings from this study, the SMEs in the Malaysian IT industry were divided into four categories, namely, highly innovative, innovative, inventive, and non innovative. The patterns of knowledge acquisition and interactive learning vary among the different categories of firms, and on the whole, vertical linkages with suppliers were found to be the most significant. Finally, support through the provision of funding was considered to be among the most important roles of the government in promoting innovation in SMEs in the Malaysian IT industry. (author)

Good quality products or services are no longer adequate to guarantee the sustainability of a company in the present competitive business. Prior research has developed various innovation models with the hope to better understand the innovativeness of the company. Due to countless definitions, indicators, factors, parameter and approaches in the study of innovation, it is difficult to ensure which one will best suit the Malaysian-owned company innovativeness. This paper aims to provide a theoretical background to support the framework of the innovation value chain capability in Malaysian-owned Company. The theoretical framework was based on the literature reviews, expert interviews and focus group study. The framework will be used to predict and assess the innovation value chain capability in Malaysian-owned company.

A perspective of the Malaysian highway energy consumption and future power supply

International Nuclear Information System (INIS)

Saqr, Khalid M.; Musa, Md. Nor

2011-01-01

In this short communication, we discuss the energy consumption trends in the Malaysian road transport sector, with a special emphasis on the energy losses due to vehicle aerodynamic drag on highways. The recent trends of energy consumption in the Malaysian road transport sector are reviewed. It is evidently shown that the aerodynamic losses represented exceed 1.2 MTOE annually since 2002. A novel concept of vertical-axis wind turbine (VAWT) farms for harvesting aerodynamic energy losses on Malaysian highways is preliminarily proposed. The novel concept aims at providing a sustainable and green energy source for the lighting of the highway network in the country.

Speech Disfluencies and Mispronunciations in English Oral Communication among Malaysian Undergraduates

Directory of Open Access Journals (Sweden)

Sarah Yong Enxhi

2012-11-01

Full Text Available The common perception of Malaysians is that they are unable to speak fluently and communicate effectively in the English language as most Malaysians do not speak English as their first language. In a country that is full of diversity in terms of race and culture, it is only natural for Malaysians to be influenced by their first language when using English as their second language. This, however, creates a problem for undergraduates who are looking for job opportunities in both local and international companies because a potential employee’s ability to communicate smoothly in English is an important criteria used by employers. This study intends to shed light on the occurrence of speech disfluencies and mispronunciations among undergraduates of a Malaysian university as well as to provide an explanation for those mispronunciations by comparing the phonetic system of the English language with the Malay and Mandarin language. With the results of this study, it is hoped that actions and measures can be taken by the academic authorities and other relevant parties to gradually improve the oral proficiency skills of undergraduates and help them to be more marketable in the future.

Highlights: • Ag NPs were deposited onto the surface of bamboo timber by silver mirror reaction. • The Ag NPs made the intrinsic insulating bamboo timber have a high conductivity. • The modified surfaces displayed superhydrophobicity even for corrosive solutions. - Abstract: Silver nanoparticles (Ag NPs) were successfully in situ deposited onto the surface of the bamboo timber through a simple silver mirror reaction. Scanning electron microscopy (SEM) images showed that the surface of the bamboo timber was densely covered with the uniform Ag NPs, which made the intrinsic insulating bamboo timber conductive. With further modification by fluoroalkylsilane (FAS), the Ag NPs-covered bamboo timber showed superhydrophobicity with the water contact angle (WCA) of 155°. Simultaneously, the modified bamboo timber displayed a durable and robust superhydrophobic property even under corrosive solutions including acidic, alkali and NaCl solutions with different molar concentrations. Especially in harsh conditions of boiling water or intense water stirring, the modified bamboo timber remained superhydrophobicity and high conductivity.

Edward Wong Sek Khin

2015-06-01

Full Text Available This study examined the relationship between control management and family business performance in the Malaysian context. It has two objectives, the first being to determine the relationship of organizational credit control policy and procedures, employee development and motivation, and intelligence collection systems to subsequent collection reports in Malaysian family SMEs. The second objective is to investigate the moderating effect of participation in decision-making and work effort towards innovation and business performance. This is a descriptive study involving 90 senior executives employed in 90 Malaysian family SMEs/firms. A correlation analysis from this study confirmed previous researchers’ observations that high-level organizational commitment to credit control management is linked to improvements in business performance. The results suggest that three components – credit policy, employee development, and intelligence collection systems – are the most important predictors for the efficiency and effectiveness of credit control management.

Full Text Available Hypertension is a common chronic disease in the elderly. This study aimed to determine the effects of age, ethnicity, gender, education, marital status, nutritional parameters, and blood elements on the risk of high blood pressure in the Malaysian elderly. This research was conducted on a group of 2322 non-institutionalized Malaysian elderly. The hierarchy binary logistic regression analysis was applied to estimate the risk of hypertension in respondents. Approximately, 45.61% of subjects had hypertension. The findings indicated that the female gender (Odds ratio (OR = 1.54, an increase in body weight (OR = 1.61, and an increase in the blood levels of albumin (OR = 1.51, glucose (OR = 1.92, and triglycerides (OR = 1.27 significantly increased the risk of hypertension in subjects (p < 0.05. Conversely, an increase in both dietary carbohydrates (OR = 0.74, and blood cholesterol level (OR = 0.42 significantly reduced the risk of hypertension in samples (p < 0.05. Furthermore, the results showed that ethnicity was a non-relevant factor to increase the risk of hypertension in subjects. It was concluded that female gender, an increase in body weight, and an increase in the blood levels of glucose, triglycerides, and albumin enhanced the risk of high blood pressure in the Malaysian elderly. In addition, an increase in both dietary carbohydrates and blood cholesterol level decreased hypertension in subjects.

Anatomy learning styles and strategies among Jordanian and Malaysian medical students: the impact of culture on learning anatomy.

Science.gov (United States)

Mustafa, Ayman G; Allouh, Mohammed Z; Mustafa, Intisar G; Hoja, Ibrahim M

2013-07-01

The study aims to investigate anatomy learning styles and strategies of Jordanian and Malaysian medical students at the Jordan University of Science and Technology. The study is a cross-sectional questionnaire-based study. Students' responses for the questionnaire were numerically coded, and the results were analyzed to reveal statistically significant differences between Jordanian and Malaysian students. The results showed that Jordanian medical students were less interested in using cadavers in learning anatomy than Malaysian medical students. However, similar to their Malaysian counterparts, they prefer to employ other tools to learn anatomy like plastinated models and Internet-based resources. In addition to the aforementioned tools, Malaysian students were more interested in using cross-sectional images and making their own revision cards. Both Jordanian and Malaysian medical students were more interested in learning anatomy through clinical cases, and by system rather than by region. Moreover, it was revealed that Jordanian medical students learn anatomy more efficiently when they formulate a general view of a particular topic. Both Jordanian and Malaysian medical students also relied on reciting definitions and memorizing facts to learn anatomy. The study also reported significant differences between Jordanian and Malaysian students' perspectives on learning anatomy. The findings of the study suggest that Jordanian and Malaysian medical students posses different cultures of learning. Jordanian anatomy instructors need to consider these different learning cultures when they prepare their instructional methods and teaching materials to fulfill the educational needs of their culturally diverse students.

In any context, operation and management of transportation systems are key issues which may affect both life quality and economic development. In large urban agglomerations, an efficient public transportation system may help abate the negative externalities of private car use such as congestion, air and noise pollution, accident and fuel consumption, without excessively penalizing user travel times or zone accessibility. Thus, this study is conducted to appraise the Malaysian rural rail transit operation and management system, which are considered important as there are many issues and solution in integration of the services that need to be tackled more conscientiously. The purpose of this paper is to describe some of the most important issues on integration of services and rail transit system in Malaysian and how to solve or reduce these problems and conflicts. In this paper, it consists of the historical development of rail transit construction in Malaysia. This paper also attempts to identify the important issues related to rail transit services and integration in Malaysian rural rail operation and management system. Comparison is also conducted with other countries such as UK, France, and Japan. Finally, a critical analysis is presented in this paper by looking at the possible application for future Malaysian rail transit operation system and management, especially focusing on enhancing the quality of Malaysian rural rail transit. In conclusion, this paper is expected to successfully review and appraise the existing Malaysian rural rail transit operation and management system pertaining to issues & solution in integration. It is also hoped that reformation or transformation of present service delivery quality of the rail transit operation and management will enable Malaysia to succeed in transforming Malaysian transportation system to greater heights.

For that purpose, this paper examined the forms of inter-religious dialogues in Malaysia from the perspective of Malaysian contemporary Muslim thinkers. The methodology utilized in this study is textual analysis, particularly the writings of these thinkers on this issue. This article concludes that there are several forms of inter-religious dialogues that are easily implemented, as well as the difficult ones in the context of Malaysia due to certain obstacles.

Merican, M I

1989-09-01

Heat stroke is hardly seen in Malaysia. However, it occurs commonly in Saudi Arabia during the Haj season. Many Malaysian pilgrims are affected every year and some die. Having faced this environmental hazard for eight years, the Malaysian Medical Mission, sent each year to look after our pilgrims, modified its treatment strategy in 1988 and successfully decreased the overall morbidity and mortality of affected patients without the use of sophisticated equipment. A brief account of the management of 17 cases seen in 1988 is given. Only one died following treatment. The rest recovered fully without any residual neurological deficit or other complications.

Framework for Robustness Assessment of Timber Structures

DEFF Research Database (Denmark)

Sørensen, John Dalsgaard

2011-01-01

This paper presents a theoretical framework for the design and analysis of robustness of timber structures. This is actualized by a more4 frequent use of advanced types of timber structures with limited redundancy and serious consequences in the case of failure. Combined with increased requirements...... to efficiency in design and execution followed by increased risk of human errors has made the need of requirements to robustness of new structures essential. Further, the collapse of the Ballerup Super Arena, the bad Reichenhall Ice-Arena and a number of other structural systems during the last 10 years has...... increased the interest in robustness. Typically, modern structural design codes require that ‘the consequence of damages to structures should not be disproportional to the causes of the damages’. However, although the importance of robustness for structural design is widely recognized, the code requirements...

Muslim refugees in Southeast Asia, the Malaysian response.

Science.gov (United States)

Dorall, R F

1988-01-01

This article surveys the arrivals of Muslim refugees from countries in Southeast Asia who have not only come to Malaysia for political refuge, but who have also stayed on, in many instances integrating into the local Muslim community. The author concludes that Burmese, Thai, and Filipino Muslim refugee-cum-migrants, and the estimated 500,000 illegal Indonesian migrant workers in East and Peninsular Malaysia make the presence of economic migrants in Malaysia's towns and rural sectors a far more pressing concern to Malaysians than that posed by the arrival of genuine political refugees. Only the Indonesians present in Malaysia are consistently termed by all parties as illegal migrants and some of them have been subjected to well-publicized deportation by the Malaysian immigration authorities. Sympathy for fellow-Muslims in distress explains Malaysia's open-door policy to Muslim refugees. The Koran specifically enjoins Muslims to assist Muslim refugees who have been persecuted by others. However, the necessity to maintain regional political and military alliances, principally as a bulwark against Communism, and the Malay--Non-Malay, Muslim--Non-Muslim dichotomy in Malaysia which almost evenly divides Malaysia's 16 million population into mutually antagonistic halves, results in any overt public policy in favor of Malays and Muslims to be immediately denounced by the other half of the population as a move against the Non-Malays and Non-Muslims. Without political and media attention, the refugees live wherever they can find work, as do hundreds of thousands of mainly Indonesian illegal migrant workers. They surreptitiously get their children admitted to public schools, and through bribery, can even get Malaysian identification papers. Malaysia is a relatively tranquil haven for Malaysia's Muslim refugees compared to their homelands, but their continued stay remains dependent on the ever-present struggle for more equitable sharing of political and economic power between

Full Text Available This study examines the level of intellectual capital disclosure among the 32 Malaysian GLCs by comparing with the Non-GLCs for the period 2007-2009. In addition, this study also investigates the impact of board structure on the intellectual capital disclosure of Malaysian GLCs. The board structure mechanisms comprise; board composition, role duality, board size and cross directorship. The control variables consist of the company-specific characteristics –leverage, profitability and age of the company. The content analysis is used to extract the intellectual capital disclosure items from the annual report. The results show that the GLCs disclosed more intellectual capital information than Non-GLCs. Board size and leverage are significant and positively related to the intellectual capital disclosure of Malaysian GLCs.

Ismi Rajiani

2013-05-01

Full Text Available 1024x768 The rise of the emerging-market countries offers both developing and developed countries a unique opportunity to gain the benefits of a truly international economy. Consequently, it is imperative to advance our knowledge of emerging-market countries MNC emergence and competitiveness including Malaysian firms on how will they position their products strategically? Based on the framework of Porter’s Generic Strategy this paper is composed of price/ volume segments and impacts on product strategy theory. The aim is to identify crucial triggering cues and focus areas for Malaysian companies and measure what role these play in different segments. This study argues that some Malaysian companies will reposition themselves strategically when internationalizing and that they will focus on other factors or triggering cues when doing so not merely adapting the prevalent price leadership strategy.

LAUGHING AT OURSELVES: REFLECTING MALAYSIAN ETHNIC DISPARITIES

Directory of Open Access Journals (Sweden)

SWAGATA SINHA ROY

2014-05-01

Full Text Available Malaysia’s various ethnic groups make interesting study both sociologically and culturally. With such a heady mix of cultural elements to explore, it is often natural that the many groups stumble upon ‘rare gems’ that reflect their ‘Malaysianess’. Have Malaysians really ever appreciated the many and varied aspects of culture that they are seemingly suddenly thrown into? Do we embrace these happily or are we constantly rejecting them? Fortunately, through the medium of film, we are, from time to time, allowed to reflect on our obvious similarities and even more apparent disparities. In this paper, we explore the culture and perceptions of people from the major ethnic groups that are the human base of this very country. When was it we have last laughed at ourselves … heartily? Nasi Lemak 2.0 provides an interesting, if not disturbing insight into the workings of the Malaysian ‘mind’. Nasi Lemak 2.0 was released on 8th September 2011 and impacted a whole generation of Malaysians. The characters have been well chosen and have done a wonderful job of being representations of the various communities in this nation. Ethnocentrism is a reality and often rears its head, ‘ugly’ or otherwise in several situations. Are we able to grapple with the levels of ethnocentrism that we encounter? These are some of the issues that will trigger much debate and discussion among ourselves and perhaps also reflect our cores.

Velocity and uniformity of air circulation in conventional kilns for sawn timber

Directory of Open Access Journals (Sweden)

Kolin Branko

2012-01-01

Full Text Available This paper presents the results of a research of velocity of air circulation in the conventional kiln drying of sawn timber and its influence on the uniformity of final moisture content. The data showed that the air velocity (between 0.8 - 1.2 m•s -1 is significantly lower than the one that is optimal for timber drying of coniferous species (3 - 4 m•s-1. This results in a reduction in the capacity of installations for drying, increased energy (thermal and electrical consumption and thereby increase in the cost of drying. The correlation between the speed of air circulation and the final MC of timber due to prolonged drying was not established. Recommendations that should eliminate the identified deficiencies are also given.

High-frequency and microwave heating as a pretreatment to kiln drying of hollowed-out timber

International Nuclear Information System (INIS)

Yamada, N.; Okumura, S.; Taniguchi, Y.

2001-01-01

To dry hollowed-out timber without V-shaped drying checks, its inner part should be dried faster than the outer part. The feasibility of high frequency heating and microwave heating as a pretreatment of kiln drying of hollow timber was examined. During high frequency heating, the top and bottom parts of the timber were dried faster than the right and left parts because the central hollow acts as an air-gap. The outer part dried faster than the inner part during microwave heating, probably because of insufficient penetration of microwave energy into the inner part. The uneven heating of hollowed timber was improved by turning the specimen around its axis during high frequency heating and by setting the specimen upright in the microwave oven

Geology, Burnst Timber Creek, west of fifth meridian, Alberta

Energy Technology Data Exchange (ETDEWEB)

1966-01-01

The Burnt Timber Creek map-area lies in the southern Foothills of Alberta and includes a narrow strip of the Front Range of the Rocky Mts. along its western edge. The area may be divided into 3 principal structural units, underlain from west to east by the McConnell, Burnt Timber, and Fallentimber thrusts, respectively. McConnell thrust underlies the eastern edge of the mountains. Subsidiary folding and faulting are locally evident in the Paleozoic strata above the thrust. Beneath the McConnell thrust, Mesozoic and Paleozoic strata of the Burnt Timber thrust sheet are strongly overturned in the Panther anticline. The axis of this anticline trends northwest. A culmination along it, in the vicinity of Sheep Creek, deforms the McConnel thrust as well. A total of 16 wells have been drilled to date in 4 separate groups. Each group has revealed the presence of gas and 8 of the wells have been capped as potential gas producers. The reservoir rocks are of Mississippian and Devonian age. Shell Panther River No. 1 well (5-19-30-10W5) is remarkable in having tested at about 86% hydrogen sulfide.

Problem-Solving Skills and Suicidal Ideation Among Malaysian College Students: the Mediating Role of Hopelessness.

Science.gov (United States)

Abdollahi, Abbas; Talib, Mansor Abu; Yaacob, Siti Nor; Ismail, Zanariah

2016-04-01

Recent evidence suggests that suicidal ideation has increased among Malaysian college students over the past two decades; therefore, it is essential to increase our knowledge concerning the etiology of suicidal ideation among Malaysian college students. This study was conducted to examine the relationships between problem-solving skills, hopelessness, and suicidal ideation among Malaysian college students. The participants included 500 undergraduate students from two Malaysian public universities who completed the self-report questionnaires. Structural equation modeling estimated that college students with poor problem-solving confidence, external personal control of emotion, and avoiding style were more likely to report suicidal ideation. Hopelessness partially mediated the relationship between problem-solving skills and suicidal ideation. These findings reinforce the importance of poor problem-solving skills and hopelessness as risk factors for suicidal ideation among college students.

The phenolic acid and flavonoid contents of Malaysian Tualang, Gelam, and Borneo tropical honeys were compared to those of Manuka honey. Ferric reducing/antioxidant power assay (FRAP) and the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical-scavenging activities were also quantified. All honey extracts exhibited high phenolic contents (15.21 ± 0.51- 42.23 ± 0.64 mg/kg), flavonoid contents (11.52 ± 0.27- 25.31 ± 0.37 mg/kg), FRAP values (892.15 ± 4.97- 363.38 ± 10.57 μM Fe[II]/kg), and high IC₅₀ of DPPH radical-scavenging activities (5.24 ± 0.40- 17.51 ± 0.51 mg/mL). Total of 6 phenolic acids (gallic, syringic, benzoic, trans-cinnamic, p-coumaric, and caffeic acids) and 5 flavonoids (catechin, kaempferol, naringenin, luteolin, and apigenin) were identified. Among the Malaysian honey samples, Tualang honey had the highest contents of phenolics, and flavonoids, and DPPH radical-scavenging activities. We conclude that among Malaysian honey samples, Tualang honey is the richest in phenolic acids, and flavonoid compounds, which have strong free radical-scavenging activities. © 2011 Institute of Food Technologists®

This paper deals with an implementation of the material parameters of the connection to complex models for analysis of the timber-fiber concrete composite structures. The aim of this article is to present a possible way of idealization of the continuous contact model that approximates the actual behavior of timber-fiber reinforced concrete structures. The presented model of the connection was derived from push-out shear tests. It was approved by use of the nonlinear numerical analysis, that it can be achieved a very good compliance between results of numerical simulations and results of the experiments by a suitable choice of the material parameters of the continuous contact. Finally, an application for an analytical calculation of timber-fiber concrete composite structures is developed for the practical use in engineering praxis. The input material parameters for the analytical model was received using data from experiments.

CREDIT CONTROL MANAGEMENT AND BUSINESS PERFORMANCE : THE MALAYSIAN FAMILY SME PERSPECTIVE

Directory of Open Access Journals (Sweden)

Edward Wong Sek Khin

2015-04-01

Full Text Available This study examined the relationship between control management and family business performance in the Malaysian context. It has two objectives, the first being to determine the relationship of organizational credit control policy and procedures, employee development and motivation, and intelligence collection systems to subsequent collection reports in Malaysian family SMEs. The second objective is to investigate the moderating effect of participation in decision-making and work effort towards innovation and business performance. This is a descriptive study involving 90 senior executives employed in 90 Malaysian family SMEs/firms. A correlation analysis from this study confirmed previous researchers' observations that high-level organizational commitment to credit control management is linked to improvements in business performance. The results suggest that three components - credit policy, employee development, and intelligence collection systems - are the most important predictors for the efficiency and effectiveness of credit control management.

Full Text Available The paper aims to examine whether Malaysian Islamic banks carry out income smoothing with regards to their distribution of depositors’ return. The paper also examines the extent Malaysian Islamic banks engage earnings and capital management in their distribution of depositors’ return. This empirical study uses balanced panel data from 16 Malaysian Islamic banks, for the period 2008-2012. The regression model is estimated using random effects specifications. The findings indicate that the earnings before tax, zakat, and provision have a positive but insignificant effect on distribution of depositors’ return (DDR whilst the total capital before provision has a positive and significant effect on the DDR. These findings suggest that Islamic banks carry out income smoothing on the distribution of depositors’ return via capital management. Islamic banks also smooth their earnings through distribution of depositors’ return to avoid earnings troughs when earnings are poor. The findings shows prudence exercise among Malaysian Islamic banks with the objectives of mitigating displaced commercial risk (DCR, which involves massive withdrawal and bank runs risks.

Full Text Available The norms and standards for design of timber bridges, as well as other structures built from this material, were obsolete, design standards that were used dated from 1978 to 1980. The introduction of European Standards has created a new legislative framework in the field of designing and building timber bridges. Currently the design of such constructions use Norm NP 005-2003 and SR EN 1995-1-1: 2004 Eurocode 5: Design of timber structures. Part 1-1: General. Common rules and rules for buildings, SR EN 1995-2: 2005 Eurocode 5: Design of timber structures. Part 2: Bridges, along with their national annexes. The aim of this paper is to analyze the design of the beams for timber bridges in parallel, using on one hand Norm NP 005 - 2003, and on the other hand provisions of European standards. The design requirements for both norms as well as the results of a case study for a structural element of a timber bridge will be presented.

Full Text Available Male osteoporosis in Malaysia is a largely neglected problem. Therefore, a bone health study in men using quantitative ultrasonometry was launched as part of the Malaysian Aging Men Study in 2009–2012. This review aimed to summarize the findings of the aforementioned bone health study. The study examined the bone health of Chinese and Malaysian men aged 20 years and above living in Kuala Lumpur using a quantitative ultrasound device. Participants answered a questionnaire on their demographic details and physical activity status. Body anthropometry of the participants was measured and their blood collected for biochemical analysis. Results showed that a significant proportion of the Malaysian Chinese and Malay men had suboptimal bone health indicated by calcaneal speed of sound and vitamin D status. Age-related decline of the calcaneal speed of sound in these men was gradual and biphasic without ethnic difference. Body anthropometry such as height, weight, body mass index, and body fat percentage contributed to the variation of the calcaneal speed of sound in Malaysian men. Age-related changes in testosterone, insulin-like growth factor 1, and thyroid stimulating hormone also influenced the calcaneal speed of sound in these men. This study serves as a reminder that male osteoporosis in Malaysia should be an issue of concern. It is also a basis for a more comprehensive study on bone health in men in the future.

To determine the susceptibility status of Aedes albopictus with and without Wolbachia to the four dengue virus serotypes. Two newly colonised colonies of Ae. albopictus from the wild were used for the study. One colony was naturally infected with Wolbachia while in the other Wolbachia was removed by tetracycline treatment. Both colonies were orally infected with dengue virus-infected fresh blood meal. Dengue virus load was measured using quantitative RT-PCR at four-time intervals in the salivary glands, midguts and ovaries. Wolbachia did not significantly affect Malaysian Ae. albopictus dengue infection or the dissemination rate for all four dengue virus serotypes. Malaysian Ae. albopictus had the highest replication kinetics for DENV-1 and the highest salivary gland and midgut infection rate for DENV-4. Wolbachia, which naturally exists in Malaysian Ae. albopictus, does not significantly affect dengue virus replication. Malaysian Ae. albopictus is susceptible to dengue virus infections and capable of transmitting dengue virus, especially DENV-1 and DENV-4. Removal of Wolbachia from Malaysian Ae. albopictus would not reduce their susceptibility status. © 2017 John Wiley & Sons Ltd.

Demeshok Vitalii

2017-01-01

Full Text Available In the article, the results of the study of behavior of timber slab under influence of fire with the standard “time-temperature” curve are presented. The finite element method was used for it. For the calculation we constructed a grid models of timber slabs. As a result of solution of the thermal problem was obtained temperature distribution and the graphs of maximum deflection of timber slabs and its slew rate depending on the time of the test. The obtained graphs allow to obtain data on the occurrence of the limit state of loss of bearing capacity by comparing current values of displacements and velocities with the maximum allowable. Analysis of the graphs shows that the criteria limit state of loss of bearing capacity does not occur. Calculation method of evaluating the fire resistance of timber slabs was developed. For it use database about strain-stress state of this slabs in conditions of influence of the fire.

Recent findings have shown that the rs1042714 (Gln27Glu) single-nucleotide polymorphism (SNP) on the β2-adrenoceptor gene may predispose to obesity. The findings from other studies carried on different populations, however, have been inconsistent. The authors investigated the association between the rs1042714 SNP with obesity-related parameters. DNA of 672 Malaysian Malays was analyzed using real-time polymerase chain reaction. Univariate and multivariate linear regression analyses revealed significant associations between rs1042714 and diastolic blood pressure in the pooled Malaysian Malay subjects under additive and recessive models. After gender stratification, however, a significant association was found between the rs1042714 and triglyceride and the rs1042714 and log-transformed high-density lipoprotein cholesterol levels in Malaysian Malay men. No significant association was found between the SNP and log-transformed body mass index. This polymorphism may have an important role in the development of obesity-related traits in Malaysian Malays. Gender is an effect modifier for the effect of the rs1042714 polymorphism on obesity-related traits in Malaysian Malays. © 2011 APJPH.

Reinforcement of Bolted Timber Joints Using GFRP Sheets in Poplar and Pine Woods

Directory of Open Access Journals (Sweden)

Mehrab Madhoushi

2013-01-01

Full Text Available Failure in timber structures occurs mainly in crucial points such as joints areas. Therefore, the idea of using composite sheets in timber joints has been intro-duced as a method in order to increase the strength and ductility behaviour of timber joints. This research aims to study the behaviour of bolted joints in poplar and pine woods, which are reinforced by two types of GFRP sheets. A single shear bolted joint consisted of 3 timber members whose length and width were 30 cm in length and 5 cm in width. The thickness of each member was 4 cm for internal part and 2 cm for external part. The employed steel bolt was 10 cm in length and 1 cm in diameter. In this respect, one layer of GFRP sheet was used to be bonded to timber members by using epoxy resin and left between the clamps for 24 hours. They were then kept at room temperature for three weeks. Also the effect of adding a wood veneer on the reinforced joints was investigated. The tensile strength of the reinforced and control samples (un-reinforced joints was measured according to ASTM D5652-92 standard. The results show that the reinforced samples have higher tensile strength compared to that of reinforced joints, although it is not statistically signifcant. Also, two types of sheets infuence the joint behaviour as the reinforced joints display more ductility behaviour.

Mushrooms, trees, and money: value estimates of commercial mushrooms and timber in the pacific northwest.

Science.gov (United States)

Alexander, Susan J; Pilz, David; Weber, Nancy S; Brown, Ed; Rockwell, Victoria A

2002-07-01

Wild edible mushrooms are harvested in the forests of the Pacific Northwest, where both trees and mushrooms grow in the same landscape. Although there has been some discussion about the value of trees and mushrooms individually, little information exists about the joint production of, and value for, these two forest products. Through four case studies, the information needed to determine production and value for three wild mushroom species in different forests of the Pacific Northwest is described, and present values for several different forest management scenarios are presented. The values for timber and for mushrooms are site- and species-specific. On the Olympic Peninsula in Washington, timber is highly valued and chanterelles are a low-value product by weight; timber has a soil expectation value (SEV) 12 to 200 times higher than chanterelles. In south-central Oregon, timber and American matsutake mushrooms have the potential to have about the same SEV. In eastern Oregon, timber is worth 20 to 110 times as much as the morels that grow in the forest. Production economics is concerned with choices about how much and what to produce with what resources. The choices are influenced by changes in technical and economic circumstances. Through our description and analysis of the necessary definitions and assumptions to assess value in joint production of timber and wild mushrooms, we found that values are sensitive to assumptions about changes in forest management, yields for mushrooms and trees, and costs.

Malaysian University Students’ Attitudes towards Six Varieties of Accented Speech in English

2014-10-01

Full Text Available Previous language attitude studies indicated that in many countries all over the world, English language learners perceived native accents either American or British, more positively than the non-native accents such as the Japanese, Korean, and Austrian accents. However, in Malaysia it is still unclear which accent Malaysian learners of English tend to perceive more positively (Pillai 2009. The verbal-guise technique and accent recognition item were adopted as indirect and direct instruments in gathering data to obtain data to clarify the inquiry. The sample includes 120 Malaysian university students and they were immersed in several speech accent situations to elicit feedback on their perceptions. Essentially two research questions are addressed: 1 What are Malaysian university students’ attitudes toward native and non-native English accents? 2 How familiar are students with accents?  The results indicated that the students had a bias towards in-group accent, meaning that they evaluated non-native lecturers’ accents more positively. These results supported the ‘social identity theory’ consistent with many previous language attitude studies of this nature. The Malaysian students were seen to be able to distinguish between native and non-native accents although there was much confusion between British and American accents.

Emergence of chikungunya seropositivity in healthy Malaysian adults residing in outbreak-free locations: Chikungunya seroprevalence results from the Malaysian Cohort

Science.gov (United States)

2013-01-01

Background In 1998, Malaysia experienced its first chikungunya virus (CHIKV) outbreak in the suburban areas followed by another two in 2006 (rural areas) and 2008 (urban areas), respectively. Nevertheless, there is still a lack of documented data regarding the magnitude of CHIKV exposure in the Malaysian population. The aim of this study was to determine the extent of chikungunya virus infection in healthy Malaysian adults residing in outbreak-free locations. Methods A cross sectional study of chikungunya (CHIK) seroprevalence was carried out in 2009 amongst The Malaysian Cohort participants living in four states (Kuala Lumpur, Selangor, Pahang and Negeri Sembilan). A total of 945 participants were randomly identified for the study. Potential risk factors for CHIK infection were determined via questionnaires, and IgG antibodies against CHIK were detected by an enzyme-linked immunosorbent assay. Logistic regression identified risk factors associated with CHIK seropositivity, while geographical information system was used for visual and spatial analysis. Results From the 945 serum samples tested, 5.9% was positive for CHIK IgG. Being male, Malay, rural occupancy and Negeri Sembilan residency were identified as univariate predictors for CHIK seropositivity, while multivariate analysis identified being male and rural occupancy as risk factors. Conclusions This study provided evidence that CHIK is slowly emerging in Malaysia. Although the current baseline seroprevalence is low in this country, increasing number of CHIK cases reported to the Malaysia Ministry of Health imply the possibility of CHIK virus becoming endemic in Malaysia.

Leakage Implications for European Timber Markets from Reducing Deforestation in Developing Countries

Directory of Open Access Journals (Sweden)

Mattias Boman

2012-08-01

Full Text Available Forest management strategies and policies such as REDD (reduced emissions from deforestation and forest degradation may have unintentional implications for forest sectors in countries not targeted by such policies. The success of a policy effort like REDD would result in a significant reduction in deforestation and forest degradation and an ensuing reduction in the supply of natural forest timber production within participating countries. This could in turn result in price increases, inducing a supply response outside project boundaries with possible implications for forest management as well as global carbon emissions. This paper reviews the literature to discern potential timber market implications for countries sourcing wood products from developing countries affected by REDD related conservation efforts. The literature reviewed shows varying degrees of market effects leakage—policy actions in one place creating incentives for third parties to increase timber harvesting elsewhere through the price mechanism—ranging from negligible to substantial. However, wood products in the studies reviewed are dealt with on quite an aggregated scale and are assumed to be more or less perfect substitutes for wood products outside conservation effort boundaries. The review suggests that a thorough mapping of the end-uses of tropical timber is needed to comprehensively analyze impacts on wood-product markets in regions such as Europe from conservation efforts in tropical developing countries. The types of tropical timber expected to be affected, in which applications they are used, which are the most likely substitutes and where they would be sourced, are issues that, along with empirical analysis of supply and demand price elasticities and degree of substitutability, should be investigated when assessing the overall effectiveness of REDD.

Sustainability and Security: Timber Certification in Asia-Pacific Region

Directory of Open Access Journals (Sweden)

Antonina Ivanova

2008-10-01

Full Text Available The expansion of sustainable development initiatives since the 1990’s reflected an emphasis on integrated solutions to economic development, socio-political stability and environmental health in the global community. In the same context the traditional concept of security needed to be open in two directions. First, the notion of security should no longer be applied only to the military realm, but also to the economic, the societal, the environmental, and the political fields. Second, the referent object of the “security” should not be conceptualized solely in terms of the state, but should embrace the individual below the state, and the international system above it. The forests industry timber certification in Asia-Pacific region has been selected as a case study because it is an excellent example to illustrate the links between the sustainable development and the environmental security, including also certain elements of economic security. This article is presenting a critical overview of the forest industry and the status of timber certification globally, with an emphasis on Asia – Pacific countries applying the Systemic Thinking approach. In conclusion, an outlook is presented concerning the future of timber certification and possible impacts on security and sustainable development.

Timber Chips as the Insulation Material for Energy Saving in Prefabricated Offices

Directory of Open Access Journals (Sweden)

Yupeng Wang

2016-06-01

Full Text Available This research demonstrates the feasibility of a roof insulation method for prefabricated offices that uses vinyl packed timber chips to reduce air conditioning loads (hereinafter referred to as AC loads and which also improves indoor thermal comfort. The advantages of the new roof insulation method were revealed through comparing the impacts of four roof types on prefabricated offices. The AC load and indoor thermal comfort (surface temperature and air temperature were evaluated. The disposal of scrap timber discarded from building construction projects is costing money, and is also a waste of natural resources. The assessment of a new roof insulation method with timber chips demonstrates the advanced usage of timber chips, reducing the environmental load in the building construction process. On the other hand, since prefabricated offices have lower thermal storage capacities and are less airtight than RC (reinforced concrete or S (steel structured buildings, the AC load consumption and indoor thermal comfort exacerbation in prefabricated offices is more serious. Especially in summer, a large amount of solar energy absorption from the roof raises the indoor air temperature and significantly increases the cooling load. This research contributes to the environmental design for prefabricated offices, and develops a method for the reuse of wood chips.

Hinged roof timber

1980-08-07

A hinged roof timer is suggested which includes a beam with prong and loop on the end which have openings in the form of ring slits for the distance wedges and round for the pins. In this case the opening of the distance wedge in the ring is arranged in relation to the opening for the pin closer to the end of the beam, and in the prong, in the opposite order. In order to improve the operating quality by guaranteeing active support of the cantilever roof timber without increasing its overall dimensions for the height of the opening for the distance wedge in the prong and the ring, beams are arranged axisymmetrically to the longitudinal axis.

Extant contents of chromium, copper and arsenic in waste CCA-treated timber

Chiba, Keiko; Uchida, Shinpei; Honma, Yoshinori; Sera, Koichiro; Saitoh, Katsumi

2009-01-01

The segregation and disposal of chromated copper arsenate (CCA)-treated wood waste when recycling building waste materials is a serious issue. We examined the contents of CCA preserved cedar timber by PIXE analysis. CCA preserved timber contained large amounts of these metals both on the surface and core of the wood. The ratio of chromium, copper and arsenic contained on the surface was 1:2:1, and in contrast, the ratio in the core was 1:1:2. In other words, the arsenic content was highest in the core. Moreover, the chemical form of arsenic in both parts of the wood was only inorganic arsenic; the same form of arsenic in preservative components known as carcinogenic substances. These findings mean that the complete separation of waste CCA preserved timber from construction and demolition wood is needed. (author)

2015-10-01

To characterize the association with Type 2 diabetes of known Type 2 diabetes risk variants in people in Malaysia of Malay, Chinese and Indian ancestry who participated in the Malaysian Cohort project. We genotyped 1604 people of Malay ancestry (722 cases, 882 controls), 1654 of Chinese ancestry (819 cases, 835 controls) and 1728 of Indian ancestry (851 cases, 877 controls). First, 62 candidate single-nucleotide polymorphisms previously associated with Type 2 diabetes were assessed for association via logistic regression within ancestral groups and then across ancestral groups using a meta-analysis. Second, estimated odds ratios were assessed for excess directional concordance with previously studied populations. Third, a genetic risk score aggregating allele dosage across the candidate single-nucleotide polymorphisms was tested for association within and across ancestral groups. After Bonferroni correction, seven individual single-nucleotide polymorphisms were associated with Type 2 diabetes in the combined Malaysian sample. We observed a highly significant excess in concordance of effect directions between Malaysian and previously studied populations. The genetic risk score was strongly associated with Type 2 diabetes in all Malaysian groups, explaining from 1.0 to 1.7% of total Type 2 diabetes risk variance. This study suggests there is substantial overlap of the genetic risk alleles underlying Type 2 diabetes in Malaysian and other populations. © 2015 The Authors. Diabetic Medicine © 2015 Diabetes UK.

Essential Oil Compositions of Malaysian Lauraceae: A Mini Review

Directory of Open Access Journals (Sweden)

Wan Mohd Nuzul Hakimi Salleh, Farediah Ahmad * , Khong Heng Yen, Razauden Mohamed Zulkifli

2016-03-01

Full Text Available Essential oils have been largely employed for human need due to their antibacterial, antifungal and insecticidal activities. At present, approximately 3000 essential oils are known, 300 of which are commercially important. Essential oils or some of their components are used in perfumes and make-up products, sanitary products, dentistry, agriculture, as food preservers and additives, and as natural remedies. The essential oil compositions of Malaysian Lauraceae family have been investigated for many years. In the recent years, studies on the essential oils of the species have been progressing and many of them have reported interesting pharmacological activities. In this article, we summarized and updated the chemical compositions and biological activities of Malaysian Lauraceae. Throughout our literature review, only four genera which are Lindera, Beilschmiedia, Litsea, and Cinnamomum have been studied for their essential oil compositions in Malaysia. They were found to contain mainly safrole, eugenol, linalool, camphor, benzyl benzoate or cinnamaldehyde as major components. There were significant priorities to find out the details of the chemical compositions of the essential oils from Malaysian Lauraceae. Therefore, more clinical studies on the toxicity of the essential oil of the species are also crucial to ensure their safety and to assess their eligibility to be used as the sources of modern medicines.

Representation of Business Culture in Selected Malaysian Short Stories

Directory of Open Access Journals (Sweden)

Zanirah Wahab

2016-11-01

Full Text Available Globalisation has brought numerous changes in all aspects of life especially in the economic sector. For the past few decades, the importance of economic growth and achievement has become the “obsession” of people around the world. Malaysia is no exception to this economic globalisation whirlwind. As well-known business hub with cutting edge technologies and blooming business enterprises, economic globalisation has shifted the way Malaysian society view things or connect with one another. This paper explores how business culture is represented in Malaysian short stories as well as examines the stand of the writers regarding the impact of economic globalisation on their society. In doing so, this paper compares and critically analyses three - selected short stories in the light of globalisation theory. The five main characteristics of globalisation namely, internationalisation, liberalisation, universalisation, westernisation and deterritorialisation are taken into account while dissecting these literary works. From the analysis, each writer voices out similar concerns regarding the impact of economic globalisation on their society. Malaysian fictions are preoccupied with the erosion of good values and the nation’s physical changes due to economic globalisation. The parallel stand demonstrates that regardless of their ethnicity and gender, they react uniformly to the changes.

Trade-offs between carbon stocks and timber recovery in tropical forests are mediated by logging intensity.

Science.gov (United States)

Roopsind, Anand; Caughlin, T Trevor; van der Hout, Peter; Arets, Eric; Putz, Francis E

2018-03-30

Forest degradation accounts for ~ 70% of total carbon losses from tropical forests. Substantial emissions are from selective logging, a land-use activity that decreases forest carbon density. To maintain carbon values in selectively logged forests, climate change mitigation policies and government agencies promote the adoption of reduced-impact logging (RIL) practices. However, whether RIL will maintain both carbon and timber values in managed tropical forests over time remains uncertain. In this study, we quantify the recovery of timber stocks and aboveground carbon at an experimental site where forests were subjected to different intensities of RIL (4 trees ha -1 , 8 trees ha -1 , and 16 trees ha -1 ). Our census data spans 20 years post-logging and 17 years after the liberation of future crop trees from competition in a tropical forest on the Guiana Shield, a globally important forest carbon reservoir. We model recovery of timber and carbon with a breakpoint regression that allowed us to capture elevated tree mortality immediately after logging. Recovery rates of timber and carbon were governed by the presence of residual trees (i.e., trees that persisted through the first harvest). The liberation treatment stimulated faster recovery of timber albeit at a carbon cost. Model results suggest a threshold logging intensity beyond which forests managed for timber and carbon derive few benefits from RIL, with recruitment and residual growth not sufficient to offset losses. Inclusion of the breakpoint at which carbon and timber gains outpaced post-logging mortality led to high predictive accuracy, including out-of-sample R 2 values >90%, and enabled inference on demographic changes post-logging. Our modeling framework is broadly applicable to studies that aim to quantify impacts of logging on forest recovery. Overall, we demonstrate that initial mortality drives variation in recovery rates, that the second harvest depends on old growth wood, and that timber

Cinotti, B.

2007-01-01

After dropping to 32.8 million m 3 in 2003, sales of wood harvests continue the recovery that began in 2004 and have reached 37.2 million m 3 (+ 5%) i.e., slightly more than the level reached prior to the 1999 storms (36.9 million m 3 ). Workable timber sales have increased by 5.9% up to 22.1 million m 3 but are nonetheless 4.5% below their 1999 level (23.2 million m 3 ). Industrial round-wood harvests have remained stable at 12.2 million m 3 (of which 11.8 are pulpwood). Sales of firewood have increased 23% (2.9 million m 3 ). Pre-tax roadside value of the entire wood harvest is estimated to be 1.64 billion Euro. French production of sawing timber is 9.7 million cubic metres with sawn softwood timber stagnating (+ 0.5%) and a drop in sawn hardwood timber (- 4.6%). The effects of the storms at the end of 1999 on the business cycle are no longer perceptible. Their consequences on the structure of harvests and of businesses are beginning to be understood. Average wood prices increased considerably in 2005 and 2006. These rosier market conditions for unprocessed timber could be an opportunity to continue with restructuring of the sector, in particular so as to further streamline harvests and narrow the wide gap between loggable and actually logged volumes, as well as to review the distribution of added value between the various players in the forest-based industries.

Nutrition surveys based on a representative sample of the Malaysian adult population have hitherto not been reported. In 2003, the Ministry of Health, Malaysia, conducted the Malaysian Adult Nutrition Survey (MANS), the first and largest nutrition survey in the country which aimed to provide detailed quantitative information on nutritional status, food and nutrient intakes, and physical activity pattern on a nationwide representative sample of adult subjects between the ages of 18 and 59 years. The survey covered four zones in Peninsular Malaysia (Central, Southern, Northern and East Coast), Sabah and Sarawak. This paper presents the mean and selected percentiles of energy and nutrient intake of 6886 subjects by selected demographic and socioeconomic characteristics. Energy contributions by macronutrients and dietary adequacy in relation to the Recommended Nutrient Intake for Malaysians are also described. Information on dietary intake was collected by trained nutritionists using a one day 24-hour diet recall. Dietary data were analysed using Nutritionist Pro, a diet analysis software and statistical analysis was carried out using the SPSS ver. 13.0. In most of the demographic and socioeconomic groups, males had higher mean energy (1776 kcal) and nutrient intake and percent achievement of RNI than females (1447 kcal). The proportions of calories derived from macronutrients were within the recommendations for a healthy diet. Intake of micronutrients such as iron, calcium and vitamin A was about 50% of RNI particularly in women. Sodium intake of Malaysians, not reported in earlier studies, is also made available. Under-reporting using the EI/BMR ratio was found in half of the population studied. The present study provides the first national estimates of energy and nutrient intake of the Malaysian adult population. Regular nutrition surveys are needed at the national level to provide valuable information on trends in food and nutrient intake, particularly among age

Malim, M. R.; Halim, F. A.; Murad, A.; Maad, H. A.; Annuar, N. F. M.

2017-09-01

The essential of derivatives has been discovered by researchers over recent decade. However, the conclusions made regarding the impact of derivatives on stock market volatility remains debatable. The main objective of this study is to examine the impact of derivatives on Malaysian stock market volatility by exploring FTSE Bursa Malaysia Kuala Lumpur Composite Index Futures (BMD FKLI) using FBM KLCI as the underlying asset. Generalized Autoregressive Conditional Heteroskedasticity (GARCH) (1, 1) model was employed to realize the objective. The results have shown that the introduction of futures trading has decreased the volatility of Malaysian stock market. The volatility increased vigorously during the Asian financial crisis compared to the Global financial crisis. However, the role of futures as a risk transfer is agreed as it could improve the market by decreasing the volatility in the spot market.

Juliana Abdul Wahab

2017-12-01

Full Text Available Religion and media are converging and frequently becoming a subject matter for news content and popular entertainment programmes in television and film, publishing, music as well as the new media. Religion, arguably has become part and parcel of the media environment today. In Malaysian context, during the millennium era, many locally produced ‘Islamic programmes’ started to gain popularity among Malaysian audience especially within the entertainment genre such as television drama. With the establishment of Malaysian first Islamic free-to-air television, TV Al Hijrah in 2010, this paper aims to understand the nature of Islamic content available on the station. The preliminary findings of this paper suggest that there are varieties of television programmes created and aired on TV Al Hijrah cutting across different genres meant for disseminating Islam as a way of life. Programmes available are mainly about showcasing the values of Islamic teaching and beliefs with the ultimate goal to highlight Islam as a beautiful and peaceful religion.

Science.gov (United States)

Hamid, Norsiah Abdul; Zaman, Halimah Badioze

This paper outlines the findings of research where the central idea is to define the term Knowledge Society (KS) in Malaysian context. The research focuses on three important dimensions, namely knowledge, ICT and human capital. This study adopts a modified Delphi technique to seek the important dimensions that can contribute to the development of Malaysian's KS. The Delphi technique involved ten experts in a five-round iterative and controlled feedback procedure to obtain consensus on the important dimensions and to verify the proposed definition of KS. The finding shows that all three dimensions proposed initially scored high and moderate consensus. Round One (R1) proposed an initial definition of KS and required comments and inputs from the panel. These inputs were then used to develop items for a R2 questionnaire. In R2, 56 out of 73 items scored high consensus and in R3, 63 out of 90 items scored high. R4 was conducted to re-rate the new items, in which 8 out of 17 items scored high. Other items scored moderate consensus and no item scored low or no consensus in all rounds. The final round (R5) was employed to verify the final definition of KS. Findings and discovery of this study are significant to the definition of KS and the development of a framework in the Malaysian context.

Misnon, Fauzan Amin; Hu, Yeoh Siong; Rahman, Irman Abd.; Yasir, Muhamad Samudi

2017-01-01

Malaysia had considered nuclear energy as an option for future electricity generation during the 9th Malaysia Development Plan. Since 2009, Malaysia had implemented a number of important preparatory steps towards this goal, including the establishment of Nuclear Power Corporation of Malaysia (MNPC) as first Nuclear Energy Programme Implementing Organization (NEPIO) in Malaysia. In light of the establishment of MNPC, the National Nuclear Policy was formulated in 2010 and a new comprehensive nuclear law to replace the existing Atomic Energy Licensing Act (Act 304) is currently in the pipeline. Internationally, public acceptance is generally used to gauge the acceptance of nuclear energy by the public whenever a government decides to engage in nuclear energy. A public survey was conducted in between 14 March 2016 to 10 May 2016 focusing on the Malaysian public acceptance and perception towards the implementation of nuclear energy in Malaysia. The methodology of this research was aim on finding an overview of the general knowledge, public-relation recommendation, perception and acceptance of Malaysian towards the nuclear power development program. The combination of information gathered from this study can be interpreted as an indication of the complexity surrounding the development of nuclear energy and its relationship with the unique background of Malaysian demography. This paper will focus mainly on energy-related section in the survey in comparison with nuclear energy.

Performance of Sprayed Fiber Reinforced Polymer Strengthened Timber Beams

Directory of Open Access Journals (Sweden)

S. Talukdar

2010-01-01

Full Text Available A study was carried out to investigate the use of Sprayed Fiber Reinforced Polymer (SFRP for retrofit of timber beams. A total of 10-full scale specimens were tested. Two different timber preservatives and two different bonding agents were investigated. Strengthening was characterized using load deflection diagrams. Results indicate that it is possible to enhance load-carrying capacity and energy absorption characteristics using the technique of SFRP. Of the two types of preservatives investigated, the technique appears to be more effective for the case of creosote-treated specimens, where up to a 51% improvement in load-carrying capacity and a 460% increase in the energy absorption capacity were noted. Effectiveness of the bonding agent used was dependent on the type of preservative the specimen had been treated with.

Simulation-Based Multiobjective Optimization of Timber-Glass Residential Buildings in Severe Cold Regions

Directory of Open Access Journals (Sweden)

Yunsong Han

2017-12-01

Full Text Available In the current context of increasing energy demand, timber-glass buildings will become a necessary trend in sustainable architecture in the future. Especially in severe cold zones of China, energy consumption and the visual comfort of residential buildings have attracted wide attention, and there are always trade-offs between multiple objectives. This paper aims to propose a simulation-based multiobjective optimization method to improve the daylighting, energy efficiency, and economic performance of timber-glass buildings in severe cold regions. Timber-glass building form variables have been selected as the decision variables, including building width, roof height, south and north window-to-wall ratio (WWR, window height, and orientation. A simulation-based multiobjective optimization model has been developed to optimize these performance objectives simultaneously. The results show that Daylighting Autonomy (DA presents negative correlations with Energy Use Intensity (EUI and total cost. Additionally, with an increase in DA, Useful Daylighting Illuminance (UDI demonstrates a tendency of primary increase and then decrease. Using this optimization model, four building performances have been improved from the initial generation to the final generation, which proves that simulation-based multiobjective optimization is a promising approach to improve the daylighting, energy efficiency, and economic performances of timber-glass buildings in severe cold regions.

XAS studies of the effectiveness of iron chelating treatments of Mary Rose timbers

International Nuclear Information System (INIS)

Berko, A; Schofield, E J; Chadwick, A V; Smith, A D; Jones, A M; Mosselmans, J F W

2009-01-01

The oxidation of sulfur in marine archaeological timbers under museum storage conditions is a recently identified problem, particularly for major artefacts such as historic ships excavated from the seabed. Recent work on the Vasa has stressed the role of iron in catalysing the oxidative degradation of the wood cellulose and the polyethylene glycols used to restore mechanical integrity to the timbers. In developing new treatment protocols for the long term preservation of Henry VIII of England's flagship, the Mary Rose, we are investigating the potential of chelating agents to neutralise and remove the iron products from the ships timbers. We have explored the use of aqueous solutions of chelating agents of calcium phytate, ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA) and ammonium citrate to extract the iron compounds. All of these solutions exhibit some level of iron removal; however the key is to find the most effective concentration at pH of around 7 of the reagent solution, to minimise the treatment time and find the most cost-effective treatment for the whole of the Mary Rose hull. Fe K-edge XAFS data from samples of Mary Rose timbers, before and after treatment by the chelating agents mentioned has been collected. The data collected provide valuable insights into the effectiveness of the treatment solutions.

Effects of Inhalation of Emissions from Cedar Timber on Psychological and Physiological Factors in an Indoor Environment

Directory of Open Access Journals (Sweden)

Kenichi Azuma

2016-12-01

Full Text Available Components extracted from cedar timber have been reported to have stress-reducing effects in humans. If the positive effects of cedar timber in indoor environments are scientifically proven, an indoor environment that utilizes cedar timber may contribute to the improvement or promotion of well-being in humans. In this study, we evaluated the effects of inhaling emissions of volatile constituents from cedar timber (Cryptomeria japonica on the psychological and physiological factors in indoor environments. A case-control study with a crossover design was conducted with 10 subjects occupying two rooms that were controlled for interior materials, indoor climate, and room size. Cedrol and β-eudesmol were specifically detected in the case room. However, no significant differences were observed in psychological and physiological factors. There was a significant loss in vigor in the control group from the time before entering the room to the time after leaving the room; however, this loss in vigor was not seen in the case group. Temperature conditions were higher than the indoor environmental standard in Japan but similar in the two groups. Our results showed a minor positive change in vigor among participants exposed to cedar timber for a short term. Inhalation of emissions of volatile constituents from cedar timber may have positive effects in humans; however, further research on their efficacy is needed.

This article discusses the issue of composite timber-glass I-beams, which are an interesting alternative for load-bearing beams of ceilings and roofs. The reasoning behind the use of timber-glass I-beams is the combination of the best features of both materials - this enables the creation of particularly safe beams with regard to structural stability and post-breakage load capacity. Due to the significant differences between the bonding surfaces of timber and glass, a study on the adhesion of various adhesives to both surfaces is presented at the beginning of the paper. After examination, two adhesives were selected for offering the best performance when used with composite beams. The beams were investigated using a four-point bending test under quasi-static loading.

Radioactive materials are used in Malaysian Nuclear Agency for various purposes such as research and development, calibration, tracer and irradiation. Inventory of radioactive materials is crucial for ensuring the security and control of all radioactive materials owned and used so as not to be lost or fall into the hands of people who do not have permission to possess or use it. Experience in many countries around the world proves that the improper inventory of radioactive material would lead to loss of control of radioactive materials and will eventually cause an accident of radiation exposure. Radioactive material database has been developed for the need to ensure traceability of radioactive materials in Malaysian Nuclear Agency. Records of radioactive materials are regularly updated based on the classification of the type of radionuclide, the total distribution in each building and the initial activity of radioactive sources.

Quality audits and intercomparisons are important in ensuring control of processes in any system of endeavour. Present interest is in control of dosimetry in teletherapy, there being a need to assess the extent to which there is consistent radiation dose delivery to the patient. In this study we review significant factors that impact upon radiotherapy dosimetry, focusing upon the example situation of radiotherapy delivery in Malaysia, examining existing literature in support of such efforts. A number of recommendations are made to provide for increased quality assurance and control. In addition to this study, the first level of intercomparison audit i.e. measuring beam output under reference conditions at eight selected Malaysian radiotherapy centres is checked; use being made of 9 µm core diameter Ge-doped silica fibres (Ge-9 µm). The results of Malaysian Secondary Standard Dosimetry Laboratory (SSDL) participation in the IAEA/WHO TLD postal dose audit services during the period between 2011 and 2015 will also been discussed. In conclusion, following review of the development of dosimetry audits and the conduct of one such exercise in Malaysia, it is apparent that regular periodic radiotherapy audits and intercomparison programmes should be strongly supported and implemented worldwide. The programmes to-date demonstrate these to be a good indicator of errors and of consistency between centres. A total of ei+ght beams have been checked in eight Malaysian radiotherapy centres. One out of the eight beams checked produced an unacceptable deviation; this was found to be due to unfamiliarity with the irradiation procedures. Prior to a repeat measurement, the mean ratio of measured to quoted dose was found to be 0.99 with standard deviation of 3%. Subsequent to the repeat measurement, the mean distribution was 1.00, and the standard deviation was 1.3%. - Highlights: • We review significant factors that impact upon radiotherapy dosimetry, • We carried out the

Daňková, Jana; Mec, Pavel; Majstríková, Tereza

2016-01-01

This paper presents results of experimental and mathematical analysis of stiffness characteristics of a composite timber-concrete structure. The composite timberconcrete structure presented herein is non-typical compared to similar types of building structures. The interaction between the timber and concrete part of the composite cross-section is not based on metal connecting elements, but it is ensured by a glued-in perforated mesh made of plywood. The paper presents results of experimental and mathematical analysis for material alternatives of the solution of the glued joint. The slip modulus values were determined experimentally. Data obtained from the experiment evaluated by means of regression analysis. Test results were also used as input data for the compilation of a 3D model of a composite structure by means of the 3D finite element model. On the basis of result evaluation, it can be stated that the stress-deformation behaviour at shear loading of this specific timber-concrete composite structure can be affected by the type of glue used. Parameters of the 3D model of both alternative of the structure represent well the behaviour of the composite structure and the model can be used for predicting design parameters of a building structure.

Suicide is an important public health problem for adolescents, and it is essential to increase our knowledge concerning the etiology of suicide among adolescent students. Therefore, this study was designed to examine the associations between hopelessness, depression, spirituality, and suicidal behavior, and to examine spirituality as a moderator between hopelessness, depression, and suicidal behavior among 1376 Malaysian adolescent students. The participants completed measures of depression, hopelessness, daily spiritual experience, and suicidal behavior. Structural equation modeling indicated that adolescent students high in hopelessness and depression, but also high in spirituality, had less suicidal behavior than others. These findings reinforce the importance of spirituality as a protective factor against hopelessness, depression, and suicidal behavior among Malaysian adolescent students.

Full Text Available Foreign nationals in Malaysia come from all corners of the world. They are here as migrant labour, highly skilled and professional migrants (expatriates, illegal migrants, refugees, asylum-seekers (Burmese asylum seekers with UNHCR card, forced migrants (human trafficking victims, students, and tourists. The influx of foreign nationals residing in Malaysia coincides with greater number of crime news featuring foreign nationals. This study explores the social construction of foreign nationals as the ‘other’ in the local crime news published by Malaysian newspapers. 94 news headlines and lead sentences of local crime news involving foreign nationals were identified and analysed for this study. Findings suggest that Malaysian newspapers magnify foreign nationals’ migration status in each crime news.

The common variants in the fat mass- and obesity-associated (FTO) gene have been previously found to be associated with obesity in various adult populations. The objective of the present study was to investigate whether the single nucleotide polymorphisms (SNPs) and linkage disequilibrium (LD) blocks in various regions of the FTO gene are associated with predisposition to obesity in Malaysian Malays. Thirty-one FTO SNPs were genotyped in 587 (158 obese and 429 non-obese) Malaysian Malay subjects. Obesity traits and lipid profiles were measured and single-marker association testing, LD testing, and haplotype association analysis were performed. LD analysis of the FTO SNPs revealed the presence of 57 regions with complete LD (D' = 1.0). In addition, we detected the association of rs17817288 with low-density lipoprotein cholesterol. The FTO gene may therefore be involved in lipid metabolism in Malaysian Malays. Two haplotype blocks were present in this region of the FTO gene, but no particular haplotype was found to be significantly associated with an increased risk of obesity in Malaysian Malays

Report from Council

CERN Document Server

2015-01-01

This week’s Council meeting was dominated by discussions about the long-term, sustainable future of CERN. Key points are progress on the Medium-Term Plan, the successful LHC restart, and enlargement.   The budget proposed by management for 2016 was well received, as were the measures to mitigate against the recent change in exchange rates. These items will be put to the vote in September. Discussions on CERN staff employment conditions were conducted in a constructive atmosphere this week, and will continue in future Council meetings. The Council also clearly voiced its congratulations for the smooth and successful start of LHC run 2, coming on top of a clear run of spectacular scientific and technological successes over recent years. In the current climate of austerity, these developments are a strong endorsement from the Council. Nevertheless, it would be disingenuous of me to pretend that everything is rosy. There has been an air of unease at CERN over recent months, which was v...

2011-04-01

An innovative three-story timber building, using self-centering, post-tensioned timber shear walls as the main horizontal load resisting system and lightweight composite timber-concrete floors, has recently been completed in Nelson, New Zealand. It is expected to be the trailblazer for similar but taller structures to be more widely adopted. Performance based standards require an advanced understanding of building responses and in order to meet the need for in-situ performance data the building has been subjected to forced vibration testing and instrumented for continuous monitoring using a total of about 90 data channels to capture its dynamic and long-term responses. The first part of the paper presents a brief discussion of the existing research on the seismic performance of timber frame buildings and footfall induced floor vibrations. An outline of the building structural system, focusing on the novel design solutions, is then discussed. This is followed by the description of the monitoring system. The paper emphasizes the need for optimal placement of a limited number of sensors and demonstrates how this was achieved for monitoring floor vibrations with the help of the effective independence-driving point residue (EfI-DPR) technique. A novel approach to the EfI-DPR method proposed here uses a combinatorial search algorithm that increases the chances of obtaining the globally optimal solution. Finally, the results from the forced vibration tests conducted on the whole building at different construction stages are reviewed.

2012-06-01

To assess the oral health quality of life among Malaysian dental students using the Oral Impacts on Daily Performance (OIDP) scale. Malaysian dental students of Melaka Manipal Medical College, Manipal campus, Manipal University, Manipal answered a structured questionnaire recording the demographic characteristics, behavioral characteristics and eight items of OIDP. The mean OIDP ADD and OIDP SC scores were respectively, 4.10 (sd = 5.16, range 8 - 40) and 2. 3 (sd = 2.3, range 0-8). A total of 50%, 32.9% and 28.6% of the dental students confirmed difficulties with eating, cleaning teeth and sleeping and relaxing, respectively. Statistically significant relationships were observed between OIDP (ultimate oral impact) and a count of non-clinical oral health indicators representing the second (intermediate) levels of oral impact. Logistic regression analysis revealed that dental students who were dissatisfied with their oral health had greater oral impact than their counterparts. The odds ratios for satisfaction with oral health, dental visits and frequency of brushing teeth were respectively 1.74 (0.58-5.32), 0.59 (0.11-3.24) and 1.33 (0.41-4.30). The study reports the Oral Impact on Daily Performance among Malaysian dental students and provides evidence of importance of social and behavioral characteristics in shaping dental students response.

The study revealed that the total extraction of fuel wood from different sources in villages was 2978.40 tons annum(-1), at the rate of 0.68 tons per capita annum(-1), which was mostly consumed in cooking followed by cottage industries, heating, community functions and others. The average fodder requirement per household was around 47.77 kg day(-1) with a total requirement of 14227.34 tons annum(-1). The average timber requirement per household was computed to be 0.346 m3 annum(-1) accounting for a total timber demand of 282.49 m3 annum(-1), which is mostly utilized in housing, followed by agricultural implements, rural furniture, carts and carriages, fencing, cattle shed/ store house and others. Forest biomass is the major source of fuel wood, fodder and timber for the primitive societies of the area contributing 1533.28 tons annum(-1) (51.48%) of the total fuel wood requirement, 6971.55 tons annum(-1) (49.00%) of the total fodder requirement and 136.36 m3 annum(-1) (48.27%) of the total timber requirement. The forest biomass is exposed to enormous pressure for securing the needs by the aboriginal people, posing great threat to biodiversity and environment of the region. Therefore, forest biomass conservation through intervention of alternative avenues is imperative to keep pace with the current development and future challenges in the area.

Irina Anatolyevna Kislukhina

2018-03-01

Full Text Available The article investigates the timber enterprises’ integration in Khanty-Mansiysk Autonomous Okrug — Yugra as a way to improve the efficiency of the timber industry. Currently, in the region, only 10 of 130 timber enterprises are large and mediumsized enterprises. The other companies are small and chronically underfunded. These small enterprises use outdated equipment and production technology, are unable to organize wood processing and reforestation; to develop forest infrastructure. However, the integration of timber industry enterprises can become the way to address this situation. The article discusses various types of possible enterprises’ integration, such as vertical and horizontal integrations, the combined and unrelated diversification (financial integration. The combined diversification is a mixed type of the integration of enterprises from related and unrelated industries. This type of integration is most in keeping with the characteristics of the development of timber industry of Khanty- Mansiysk Autonomous Okrug — Yugra. The combined diversification will maximize the effect from the association of enterprises. The author has justified the rationale for establishing six integrated industrial and financial associations (IIFA according to improved forest and economical zoning of Okrug area. I defined the profile of each IIFA taking into account of special aspects of forest resources as well as social and economical development characteristics of the area and demand for the products. In Khanty-Mansiysk Autonomous Okrug — Yugra, the integrated industrial and financial associations will address four critical challenges of the socio-economic development of the region. Firstly, these associations will contribute to the diversification of the economy. Secondly, they will enable the production of new types of forest products. Thirdly, the creation of the integrated industrial and financial associations will increase the efficiency in

Modeling the complex impacts of timber harvests to find optimal management regimes for Amazon tidal floodplain forests

Science.gov (United States)

Fortini, Lucas B.; Cropper, Wendell P.; Zarin, Daniel J.

2015-01-01

At the Amazon estuary, the oldest logging frontier in the Amazon, no studies have comprehensively explored the potential long-term population and yield consequences of multiple timber harvests over time. Matrix population modeling is one way to simulate long-term impacts of tree harvests, but this approach has often ignored common impacts of tree harvests including incidental damage, changes in post-harvest demography, shifts in the distribution of merchantable trees, and shifts in stand composition. We designed a matrix-based forest management model that incorporates these harvest-related impacts so resulting simulations reflect forest stand dynamics under repeated timber harvests as well as the realities of local smallholder timber management systems. Using a wide range of values for management criteria (e.g., length of cutting cycle, minimum cut diameter), we projected the long-term population dynamics and yields of hundreds of timber management regimes in the Amazon estuary, where small-scale, unmechanized logging is an important economic activity. These results were then compared to find optimal stand-level and species-specific sustainable timber management (STM) regimes using a set of timber yield and population growth indicators. Prospects for STM in Amazonian tidal floodplain forests are better than for many other tropical forests. However, generally high stock recovery rates between harvests are due to the comparatively high projected mean annualized yields from fast-growing species that effectively counterbalance the projected yield declines from other species. For Amazonian tidal floodplain forests, national management guidelines provide neither the highest yields nor the highest sustained population growth for species under management. Our research shows that management guidelines specific to a region’s ecological settings can be further refined to consider differences in species demographic responses to repeated harvests. In principle, such fine

Parents are the main decision makers for their children vaccinations. This fact makes parents' immunization knowledge and practices as predictor factors for immunization uptake and timeliness. The aim of this pilot study was to develop a reliable and valid instrument in Malaysian language to measure immunization knowledge and practice (KP) of Malaysian parents. A cross-sectional prospective pilot survey was conducted among 88 Malaysian parents who attended public health facilities that provide vaccinations. Translated immunization KP questionnaires (Bahasa Melayu version) were used. Descriptive statistics were applied, face and content validity were assessed, and internal consistency, test-retest reliability, and construct validity were determined. The mean ± standard deviation (SD) of the knowledge scores was 7.36 ± 2.29 and for practice scores was 7.13 ± 2.20. Good internal consistency was found for knowledge and practice items (Cronbach's alpha = 0.757 and 0.743 respectively); the test-retest reliability value was 0.740 (p = 0.014). A panel of three specialist pharmacists who are experts in this field judged the face and content validity of the final questionnaire. Parents with up-to-date immunized children had significantly better knowledge and practice scores than parents who did not (p Malaysian parents and therefore this version can be used in future research.

Rare earth elements (REEs) are very valuable and have high demands for advanced technology nowadays. REEs can be classified to light rare earth elements (LREEs) and heavy rare earth elements (HREEs). Malaysian rare earth ore especially monazite, is rich with LREEs compared to HREEs. Therefore a study was carried out to extract the REE from Malaysian monazite. The objectives of this study are to determine the content of REEs in Malaysian monazite leach solution, as well as to produce high grade of REEs. Concentrated sulphuric acid was used in digestion process and the filtrate containing the REEs was determined using Inductively Coupled Plasma- Mass Spectrometry (ICP-MS). Ammonia solution was used for REEs precipitation from monazite leach solution. The result indicated that REEs was successfully separated from monazite leach solution through selective precipitation using ammonia at pH 2.34 and the percentage of REEs that successfully separated was 70.03 - 81.85 %. The percentage of REEs which successfully separated from final solution was 96.05 - 99.10 %. Therefore, to have high purification of individual REEs, solvent extraction process should be carried out.

Mohd Suhaimi, Nurul Aisyah Binti; de Mey, Yann; Oude Lansink, Alfons

2017-01-01

The purpose of this paper is to measure the technical inefficiency of dairy farms and subsequently investigate the factors affecting technical inefficiency in the Malaysian dairy industry. This study uses multi-directional efficiency analysis to measure the technical inefficiency scores on a sample of 200 farm observations and single-bootstrap truncated regression model to define factors affecting technical inefficiency. Managerial and program inefficiency scores are presented for intensive and semi-intensive production systems. The results reveal marked differences in the inefficiency scores across inputs and between production systems. Intensive systems generally have lowest managerial and program inefficiency scores in the Malaysian dairy farming sector. Policy makers could use this information to advise dairy farmers to convert their farming system to the intensive system. The results suggest that the Malaysian Government should redefine its policy for providing farm finance and should target young farmers when designing training and extension programs in order to improve the performance of the dairy sector. The existing literature on Southeast Asian dairy farming has neither focused on investigating input-specific efficiency nor on comparing managerial and program efficiency. This paper aims to fill this gap.

Malaysian Container Seaport-Hinterland Connectivity: Status, Challenges and Strategies

Directory of Open Access Journals (Sweden)

Shu-Ling Chen

2016-09-01

Full Text Available This paper adopts a qualitative methodology to assess the Malaysian container seaport-hinterland connectivity from the perspective of its physical properties. The findings reveal that although Malaysia's major container seaports are connected to the hinterlands through road and rail transport, they are highly dependent on road. These seaports are also connected to inland freight facilities such as dry ports and ICDs, which are positioned as transit points to help connect exporters and importers in the hinterlands to seaports as well as facilitating regional and cross-border trades. This paper suggests that the quality of hinterland connectivity of Malaysian container seaports could be improved by implementing strategies which tackle the existing challenges including overcoming an extremely imbalanced modal split, insufficient rail capacity and limited train services, increasing road congestion and the limitations of space restriction in some inland facilities.

Innovation is among the most frequently used word in the business world today. While many businessman and executives agree that innovation is needed to sustain their long term business success, many struggle to understand the concept of innovation. This study aims to measure the understanding level of innovation among the Malaysian executives using a survey questionnaire. Questions regarding innovation were posted to the respondents and they were requested to answer either it was True or False. Each respondent was given scores for their correct answers. The score of the right answers were then categorized into low, moderate and high understanding level. Results of the survey revealed that the understanding level of innovation among the Malaysian Executives is still at moderate level thus leading to the failure of many initiatives introduced by the organization or the government.

This study aimed to determine the prevalence and early outcome of neural tube defects (NTDs) in Malaysia. This prospective study included all neonates with NTDs (spina bifida, anencephaly, encephalocoele) born in 2009 in 32 Malaysian hospitals in the Malaysian National Neonatal Network. The prevalence of NTDs was 0.42 per 1000 live births, being highest among the indigenous people of Sarawak (1.09 per 1000 live births) and lowest among Malaysians of Chinese descent (0.09 per 1000 live births). The most common type of NTDs was anencephaly (0.19 per 1000 live births), followed by spina bifida (0.11 per 1000 live births) and encephalocoele (0.07 per 1000 live births). Majority of the infants with anencephaly (94.5%, n = 51), 45.8% (n = 11) with encephalocoele and 9.5% (n = 4) with spina bifida died. The median duration of hospital stay was 4 (range: 0-161) days. NTDs were common in Malaysia. Mortality was high. Long-term monitoring of NTD prevalence following folic fortification of food is recommended.
