Edible bird’s nest (EBN) originates from South East Asia and has become the most popular food delicacy among Chinese people. The price for raw and clean EBN are around RM 4,000 and RM 8,000 per kg, respectively. Due to the high market value of EBN and low maintenance cost, people ventures and invest in bird’s nest industry. The nesting house resembles the cave is built to attract swiftlets to roost and nest in it in order to meet the world’s growing demand. Out of the blue, in 2011, the EBN’s price falls half from its original price from RM 4,000 to RM 2,000. Nitrate found in raw or unclean EBN is one of the reason price plunges and the public also worried about counterfeit EBN that made from unclear substances. Thus, this review paper aims to highlight the nutritional properties in EBN that give medicinal benefits to consumers and the adulterant in EBN to increase the property contents with the dangerous mechanism by some irresponsible producers to obtain better profit which can threatening public’s health. In relation, these matters may influence consumer’s perception on EBN contents that could harm this industry. For that reason, scientific studies determined ways of handling EBN from scratch and distinguished the adulterant in EBN to reduce consumer anxiety was also discussed. Strict standard operation procedure enforces by the Malaysian Ministry of Health to farmers and producers are required, so that Malaysia EBN would appeal to the China market. Latter it can yield a good result and the price of EBN will slowly increase.

Torque Teno Virus (TTV) is a human-infected virus that is present ubiquitously in nature. Globally, it infects up to 95% of the healthy individuals without any clinical manifestations. The widely used laboratory diagnosis of TTV infection is Polymerase chain reaction (PCR). Nevertheless, several other methods have been developed. The rapid growth of TTV variants over time has posed a challenge in estimating the global TTV infection as none of the PCR protocol has the ability to detect the entire spectrum of TTV variants. Multiple TTV epidemiological studies have been conducted among Asian population, whereas other continents showed a limited number of studies. The horizontal and vertical transmission of TTV among humans population, as well as interspecies transmission are potentially related to the global widespread of TTV infection.
Stingless bee is a diverse group of highly eusocial bees (meliponines) comprising the Meliponini subfamily of the Apidae family. Throughout the tropics, various kinds of stingless bee have been reared by beekeepers for their products (honey, propolis and bee bread) and pollination services for fruits and vegetables. This meliponiculture in logs or hives is considered safe due to the bee’s inability to sting, with the latter being more preferable for monitoring and managing the colonies and harvesting the products. The source of stingless bee colonies is depending on efficient hunting of feral colonies, which might affect the ecosystem. Following to the growing trend of bee rearing in Malaysia, mainly due to the smart branding strategy of the government through research institutes and universities, e.g. Malaysian Agricultural Research and Development Institute (MARDI), Universiti Malaysia Terengganu and Universiti Sains Malaysia, it is crucial to increase the number of honey-producing hives by colony splitting. The basis of colony splitting includes provision oviposition (POP), swarming and antennation. Colony splitting is necessary due to deforestation, to expand income generation and for entomological study purposes. A more advanced approach in colony splitting is to prepare and rear the virgin queen bee in vitro, resulting in more queens per one single colony. With the advancement in stingless bee rearing techniques, people may apply the colony splitting strategy to maximise stingless bee products and enhance crop production.
Fruit rot is a common disease that affects the quality and quantity of the produced fruits. It may happened during pre-harvest stage and usually the condition of the fruits will become worse at postharvest stage if there are no any precautions taken during the picking, storing, packaging and transporting processes. The disease is mainly caused by the infection of fungi supported by a conducive condition like susceptible hosts, relative humidity and unsuitable temperature, besides other microorganisms such as bacteria, viruses and nematodes. The infection may arise from soilborne, waterborne, windborne and insects bite transmission. Fruit rot diseases have been reported to cause by many fungal species such as Fusarium species, Alternaria species, Lasiodiplodia species, Aspergillus species, Penicillium species, Colletotrichum species and Botrytis species. This review will provide sufficient information about rot diseases on fruit, fungal species that cause the diseases, effective control methods and managements as well as economic losses and health issues related to the diseases.
The aim of this paper is to review the principles of ground-borne vibration induced by road

equipment, and developed guidelines or standards in order to indicate the threshold limit of damage and
annoyance. Measurement of ground-borne vibration is a crucial aspect in ground-borne vibration
studies that needs to be understood well. The reliability of the measurement is dependent on the
accuracy of the data collected. Thus, discussion in this review paper proceeds on the types of groundborne vibration modelling that can predict and explain the phenomenon.
Semiconductor metal oxide (SMO) as a sensing layer for gas detection has been widely used. Many researches have been performed to enhance the sensing performance including its sensitivity, reliability and selectivity. Electrical sensors that use resistivity as an indicator of its sensing are popular and well established. However, the optical based sensor is still much to explore in detecting gas. By integrating it with SMO, the sensor offers good alternative to overcome some drawbacks from electrical sensors.
Cervical cancer is one of the leading causal cancer-related fatalities in the world. Cervical cancer patients can be treated by conventional treatment such as surgery, radiotherapy, chemotherapy, medications and combination treatments. Currently, more targeted treatments are being developed to cure cervical cancer. The treatments include immunotherapy, virotherapy and gene therapy which will be discussed in this paper. In immunotherapy, the synergy of CTLA-4 suppression and PD-1/PDL-1 immune checkpoint inhibition targeting their corresponding pathways enhanced the human immune system resulting a promising treatment effects. Oncolytic viruses such as Newcastle disease virus selectively infect and kill cancerous cells/tissues without harming normal cells/tissues. This character has made them a potential modality in combating cancer which popularly known as oncolytic virotherapy. Gene therapy delivers modified genetic materials to the target cancer cells via viral and non-viral vectors. It is used to target the abnormal gene, to increase cells’ susceptibility towards drugs or conventional therapy, to induce tumour cells apoptosis, to enhance tumour cell immunogenicity recognition and to inhibit the oncogene expression. The objective of this minireview is to add to the general knowledge on aforementioned therapeutic strategies against cervical cancer.
The aim of this paper is to review the potentialities and major methodological challenges
of integrating remote sensing (RS) and geographic information system (GIS) with socioeconomic data
from published articles or book chapters. RS and GIS combined with social science (SS)(termed as
geoinformation technology) serve many applications for sustainable management and monitoring of
the environment. This combined approach gives more accurate results than the single one. It makes
information available about the trend and pattern of land use and land cover change (LUCC) with
socioeconomic variables like population, demographic or income. This combined study which links
RS and GIS with socioeconomic data can also be used successfully for monitoring transmission rate
of disease and mapping or preparing vulnerability index. For impact assessment and modelling, this
combined technology provides better results than the single one. There are some methodological
problems for the researchers to link completely two different disciplines as the object of study and
observational unit is completely different. However, this interdisciplinary study is gaining popularity
day by day to researchers from different disciplines as well as decision makers.

Furthermore, studies of user cultural needs could enhance user’s understanding and acceptance of the interface design. Thus, the purpose of this article is to review the cultural factors influencing interface design elements. Indirectly, it exhibits the concept of culture centered design.
Hevea brasiliensis is one of the popular industrial crops in Malaysia better known as rubber tree belongs to the family Euphorbiaceace. From more than 12 species of Hevea, only Hevea brasiliensis is economically exploited because the milky latex extracted from the tree is the primary source of natural rubber. As in other crops, various plant physiological conditions and pathogenic diseases influence rubber production. Brown bast is one of the most serious threats to natural rubber production. In general, high-yielding clones of rubber tree are often considered to be more susceptible to this physiological disorder also commonly termed Tapping Panel Dryness (TPD). It is estimated that brown bast leads to approximately 15-20% decrease in yield. There is no known cure for brown bast yet. However, many plantation practices manage brown bast in rubber by giving tapping rest and changing tapping panel. Hence, this review condenses the causal of brown bast, symptoms of diseases and also control of brown bast affected Hevea tree.

This study assessed the feasibility of a syntactic analysis of newspaper editorials and to test out Morenberg’s (2010) syntactic theory. The purposes of this study hence, were to develop appropriate research questions and to determine whether Morenberg’s (2010) theory could be employed for the syntactic analysis of editorials. By adopting this theory, one editorial from The Star (2018), Malaysia and two editorials from The Sun (2018a, 2018b), UK were analysed, with the intention of investigating the concept of syntax to highlight the styles and constructions in professional writing. Sentences obtained from these three editorials were broken down via tree diagramming to answer the first research question - what are the syntactic patterns used in editorials in newspapers? The tree diagrams of all sentences were then examined to answer the second research question - are there syntactic differences in editorials? The study found the basic patterns of the sentences of all editorials used mostly transitive verbs, with the inclusion of many VBE verbs and very few intransitive and two-place transitive Vc verbs. Optional elements in the syntactic patterns, however, varied according to their different orders in sentence builds. Tree diagramming of the sentences revealed few noticeable differences in terms of sentence mood, structural parallelism, employment of wh-clause as well as subject ellipsis.
Ficus carica L. or fig is the oldest fruit tree that being cultivated by man. Grouped under genus Ficus, this species is grown widely in Mediterranean region and now being cultivated in an area with temperate or sub-temperate climate. Fig planting in Malaysia is still new, which was brought by a man as a hobby at first. Fig is a unique fruit tree as some variety can produce fruits without pollination. Contain lots of carbohydrates, essential amino acids, vitamins and minerals such potassium, fibre, calcium, iron compared to other fruits, fig have become an important source of diet to people especially in Mediterranean region since ancient time.
Commercialisation of glyphosate [N-(phosphonomethyl)glycine] in the early 1970s has left a big leap in the agriculture sector. This is due to its effectiveness in controlling a wide range of weeds. Glyphosate translocates well in plants. In addition, with added surfactant in its formulae, it can also be used in wet conditions. Its ability to kill weeds by targeting the 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSPS) makes no competing herbicide analogs in its class. Considering its cost effectiveness, only small amount is needed to cover a large sector in agricultural land. The most important aspect in the success of glyphosate is the introduction of transgenic, glyphosate-resistant crops in 1996. However, glyphosate is not an environmental friendly herbicide. This systematic herbicide has raised environmental concern due to its excessive use in agriculture. Studies have shown traces of glyphosate found in drinking water. Meanwhile, it's rapid binding on soil particles possesses adverse effect to soil organisms. Glyphosate degradation in soil usually carried out by microbial activity. Microbes’ capable utilising glyphosate mainly as phosphate source. However, the activity of C-P lyase in breaking down glyphosate have not clearly understood. This review presents a collective summary on the understanding on how glyphosate works and its environmental fate.
The use of remote sensing in detecting aerosol or air pollution is not widely applied in Malaysia. The large area of coverage provided by remote sensing satellite may well be the solution to the lack of spatial coverage by the local ground air quality monitoring stations. This article discusses the application of remote sensing instruments in air quality monitoring of Malaysia. The remote sensing data is validated using ground truths either from local ground air monitoring stations or the Aerosol Robotic Network (AERONET). The correlation between remote sensing is relatively good with R from 0.5 to 0.9 depending on the satellite used. The correlation is much improved using the mixed effects algorithm applied on MODIS Aerosol Optical Depth (AOD) data. Accuracy of predicted air quality data by remote sensing is generally tested using the Root Mean Squared Error (RMSE) against the ground truths data. Besides the Geographic Information System (GIS) tools are used in manipulating the data from both remote sensing and ground stations so as to produce meaningful results such as spatio-temporal pattern mapping of air pollution. Overall the results showed that the application of remote sensing instruments in air quality monitoring in Malaysia is very useful and can be improved further.
Changes in tick-vector densities and a resultant incidence of tick-borne diseases are
caused mainly by human activities affecting the environmental ecosystem, especially in tropical
countries. As one of the most important invertebrate arthropod vectors of disease transmission, ticks
are susceptible to changes in their environment due to their sole dependence of all their life stages on
prevailing environment. Upon completion of their lifecycle, ticks depend on the availability of hosts
and other several factors related to their surroundings to survive. This review discusses the major
factors that influence the prevalence and distribution of tick-borne diseases among domestic animals
in Malaysia. It is highly imperative to understand the factors that lead to increase in tick-vector
populations, infection intensity and hence the spatial distribution of ticks and tick-borne diseases in
order to prevent their emergence and resurgence as well as to serve as a basis for effectivecontrol.
Structural buildings in seismic prone area, the required energy dissipation of strong column-weak beam especially for reinforced concrete frame structures is achievably through adequate beam-column joint strengthening connection in order to have high seismic performance. Literature investigation shows several approaches and techniques for modelling the weak joint for a typical frame structure. This paper extensively reviews those techniques, methods, concepts and their performance in improving the shear capacity for a deficient reinforced concrete beam-column joints in withstanding seismic loads. The beam-column joints performance responses showed positive. However, the need for an improved connection that will offer high ductility capacity and energy dissipation ability for post-tensioned reinforced concrete beam-column joints with continuing bottom reinforcement is highly feasible with the use of the Direct Displacement Based design philosophy. This will be of great interest for the future development of highly efficient joint system for frame structure capable of resisting significant seismic load.
