    A new method to construct the distinct Hamiltonian circuits in complete
    graphs is called Half Butterfly Method. The Half Butterfly Method used the concept
    of isomorphism in developing the distinct Hamiltonian circuits. Thus some theoretical
    works are presented throughout developing this method.

  3. Hotspots of mite new species discovery: Trombidiformes (2013-2015)
    Liu JF, Zhang ZQ
    Zootaxa, 2016 Dec 14;4208(1):zootaxa.4208.1.1.
    PMID: 27988536 DOI: 10.11646/zootaxa.4208.1.1
    This paper reveals the hotspots of new mite discovery through of a survey of type localities of new Trombidiformes species described in two journals (Systematic & Applied Acarology and Zootaxa) during the last three years (2013-2015). Taxonomically, the 491 new species of the Trombidiformes are highly unevenly distributed among 55 families with top 10 families accounting for over 66% of the total. The Eriophyidae is the top-ranked family. Geographically, these 491 new species are from 55 countries around the world and their distribution among the countries is highly uneven. The majority of these new species (69%) are from the top 10 countries and six of the top ten countries are also megadiversity countries. The top three countries are all from Asia (Iran, China and Malaysia) and they together accounted for over one third of all new species of the Trombidiformes described in the two journals during 2013-2015.

    Medium penyampaian maklumat merupakan media pengajaran utama yang digunakan dalam menyampaikan
    maklumat kepada pekerja tempatan dan juga asing dalam Kursus Induksi Keselamatan dan Kesihatan (KIKK).
    Justeru, kertas kerja ini menumpukan kepada perbincangan mengenai permasalahan serta hasil kajian lepas berkaitan
    penggunaan media penyampaian maklumat sedia ada oleh pekerja asing dalam KIKK. Kesimpulan hasil kajian
    perpustakaan mendapati terdapat beberapa masalah penggunaan media penyampaian maklumat sedia ada ini daripada
    aspek penggunaan bahasa, cara penyampaian dan medium penyampaian. Bahasa Melayu lazimnya digunakan sebagai
    bahasa pengantar semasa penyampaian maklumat dalam KIKK sama ada dalam bentuk teks mahupun penyampaian
    lisan. Namun, penggunaan Bahasa Melayu ini didapati tidak difahami oleh kebanyakan pekerja asing terutamanya
    pekerja asing bukan warga Indonesia. Cara penyampaian maklumat juga dilihat bersifat satu hala dan kurang difahami
    serta medium penyampaian yang digunakan kurang interaktif dan berbentuk presentasi. Malah, medium penyampaian
    maklumat seperti PowerPoint yang digunakan masih belum cukup kemas untuk memenuhi keperluan kerja pekerja
    asing di tapak bina yang mana teks bahasa Melayu terlalu panjang digunakan, susunan teks dan grafik tidak kemas,
    saiz teks tidak konsisten serta penggunaan grafik yang kurang jelas.

  5. Essential Oils: Extraction Techniques, Pharmaceutical And Therapeutic Potential - A Review
    Aziz ZAA, Ahmad A, Setapar SHM, Karakucuk A, Azim MM, Lokhat D, et al.
    Curr Drug Metab, 2018;19(13):1100-1110.
    PMID: 30039757 DOI: 10.2174/1389200219666180723144850
    BACKGROUND: Essential oils are liquid extracts from aromatic plants, which have numerous applications in multiple industries. There are a variety of methods used for the extraction of essential oils, with each method exhibiting certain advantages and determining the biological and physicochemical properties of the extracted oils. Essential oils from different plant species contain more than 200 constituents which are comprised of volatile and non-volatile components. The application of essential oils as antimicrobial, anticancer, anti-inflammatory and anti-viral agents is due to their effective and efficient properties, inter alia.

    METHOD: Several advanced (supercritical fluid extraction, subcritical extraction liquid, solvent-free microwave extraction) and conventional (hydrodistillation, steam distillation, hydrodiffusion, solvent extraction) methods have been discussed for the extraction of essential oils. Advanced methods are considered as the most promising extraction techniques due to less extraction time, low energy consumption, low solvent used and less carbon dioxide emission.

    CONCLUSION: This manuscript reviewed the major research studies in the field and discussed several research findings on the chemical composition of essential oils, methods of oil extraction, and application of these oils in pharmaceutical and therapeutic fields. These essential oils can be used as anticancer, antimicrobial, antiviral, and as skin permeation enhancer agents.

    PMID: 30301238 DOI: 10.3390/s18103342
    Electroencephalography (EEG) signals have great impact on the development of assistive rehabilitation devices. These signals are used as a popular tool to investigate the functions and the behavior of the human motion in recent research. The study of EEG-based control of assistive devices is still in early stages. Although the EEG-based control of assistive devices has attracted a considerable level of attention over the last few years, few studies have been carried out to systematically review these studies, as a means of offering researchers and experts a comprehensive summary of the present, state-of-the-art EEG-based control techniques used for assistive technology. Therefore, this research has three main goals. The first aim is to systematically gather, summarize, evaluate and synthesize information regarding the accuracy and the value of previous research published in the literature between 2011 and 2018. The second goal is to extensively report on the holistic, experimental outcomes of this domain in relation to current research. It is systematically performed to provide a wealthy image and grounded evidence of the current state of research covering EEG-based control for assistive rehabilitation devices to all the experts and scientists. The third goal is to recognize the gap of knowledge that demands further investigation and to recommend directions for future research in this area.

  12. Fulltext Dynamical behaviours of prey-predator fishery model with harvesting affected by toxic substances
    Keong, Ang Tau
    MATEMATIKA, 2018;34(1):143-151.
    MyJurnal
    In this paper we consider a harvesting model of predator-prey fishery in which
    the prey is directly infected by some external toxic substances. The toxic infection is
    indirectly transmitted to the predator during the feeding process. The model is a modified
    version from the classic Lotka-Volterra predator-prey model. The stability and bifurcation
    analyses are addressed. Numerical simulations of the model are performed and bifurcation
    diagrams are studied to investigate the dynamical behaviours between the predator and
    the prey. The effects of toxicity and harvesting on the stability of steady states found in
    the model are discussed.

    The taxonomic position of the rare Selangor Mud Snake (Raclitia indica) Gray to other species of homalopsids has remained uncertain due to the scarcity of specimens in collections and the lack of genetic material for comparison. Here we report the first molecular phylogenetic examination of this species based on recently acquired material. The study recovered R. indica nested within the clade of advanced, fanged homalopsids and the sister species to Erpeton tentaculatus Lácèpede. We also present notes on variation observed in the new specimens as well as range extensions for the species.

  16. The aetiology of the Tsutsugamushi disease and tropical typhus in the Federated Malay States. Part I
    Fletcher W, Lesslar JE, Lewthwaite R
    Trans R Soc Trop Med Hyg, 1928;22:161-162.
    DOI: 10.1016/S0035-9203(28)90008-5
    A short description of the tsutsugamushi disease is given, followed by a note on the conditions under which it occurs in Sumatra and the Malay States. Abandoned agricultural land which has grown up in weeds is particularly dangerous. Small rodents are the reservoirs of the virus which is carried from them to man by larval mites. Trombicula akamushi is the carrier in Japan, and T. deliensis in Sumatra. The disease has been conveyed to monkeys by inoculation and also by the bites of infected mites. A description is given of four mites which are commonly found in the ears of rats in the Malay States, and a method for the examination of the mites is described. Black rats, to the number of 130, were examined. Sixteen were trapped in an abandoned portion of an oil-palm estate where three Europeans became infected with the tsutsugamushi disease, and T. deliensis, the Sumatran carrier, was found on ten of them. Thirty rats were caught in other parts of the estate, and T. deliensis was found on nine. Thirty rats were caught in other rural districts, where the disease was not known, and T. deliensis was found on only one. Fifty-four rats caught in the town of Kuala Lumpur were examined, with the result that T. deliensis was found in none. The conclusion is reached that T. deliensis is probably the carrier in the Malay States, as it is in Sumatra.

  17. The typhus group of diseases in Malaya. Part I: The study of the virus of rural typhus in laboratory animals. Part II: The study of the virus of tsutsugamushi disease in laboratory animals
    Lewthwaite R, Savoor SR
    Br J Exp Pathol, 1936;17:1-20.
    1. A strain of the rural form of tropical typhus has been established and maintained in guinea-pigs, and is now in its 97th generation. The history and characteristics of this strain are given. The clinical criterion of infection is a well-marked febrile reaction. Scrotal swelling does not occur. Ascites invariably follows intra-peritoneal inoculation of passage virus.
    2. In more than one hundred other such attempts made in this laboratory it has proved impossible to maintain a strain beyond a few generations. Similarly all attempts to maintain the virus of the tsutsugamushi disease in guinea-pigs have failed. The guinea-pig must, therefore, be regarded as very insusceptible to the viruses of the rural typhus and tsutsugamushi group of fevers of Malaya.
    3. Infection of rabbits by the intra-ocular inoculation of the virus of rural typhus and of the tsutsugamushi disease has been readily secured. The method, based on that of Nagayo et al., and the criteria of infection, are described in detail.
    4. The white rat is readily infected with the virus of rural typhus, the infection being of the "inapparente" form. That the virus could be maintained with unabated virulence for 21 generations indicates, by the criterion of Nicolle, that rural typhus is a murine strain.
    5. Monkeys have been successfully infected by the intradermal route with the virus of rural typhus and of the tsutsugamushi disease. At the sites of inoculation, in the case of both viruses, necrotic ulcers have developed that appear to be identical with one another, and with the initial lesion of the tsutsugamushi disease in man; in all other features the experimental infections in the monkey appear to be identical. Rabbits have been similarly infected.
    6. The results of the Weil-Felix reactions of sera from rabbits and monkeys convalescent from experimental infection with rural typhus and the tsutsugamushi disease are summarized.
    7. Methods of demonstration of Rickettsia from infected guinea-pigs and rabbits are described. In morphology, distribution and staining characteristics the Rickettsia demonstrable in material from animals infected with rural typhus and with the tsutsugamushi disease are identical, and do not appear to differ from the Rickettsia orientalis of Nagayo.
    8. The experimental data secured indicate that, provided that intra-ocular inoculation is practised, the rabbit is the laboratory animal of choice in the case of the rural typhus and tsutsugamushi group of fevers (it being assumed that
    expense and scarcity make extensive use of monkeys impracticable). Further, these data stress the remarkable similarity of the behaviour of these two viruses in experimental laboratory animals-a similarity that, as will be set forth in a later paper, is fully supported by cross-immunity experiments.

  18. The typhus group of diseases in Malaya. Part V: The Weil-Felix reaction in laboratory animals
    Lewthwaite R, Savoor SR
    Br J Exp Pathol, 1936;17:214-28.
    1. The results of the Weil-Felix reactions of sera from rabbits and monkeys inoculated with human virus or virus of laboratory strains of rural typhus, urban typhus or the tsutsugamushi disease are reported and discussed; as also are corresponding results in rabbits inoculated with the virus of two strains of tropical typhus recovered from wild rats.
    2. Instances are given of a change in type of antibody response; in particular, an experience is described in which the agglutinogenic properties of a virus of a tropical typhus strain underwent a temporary change, while the immunogenic properties remained unchanged.

  19. The typhus group of diseases in Malaya. Part IV: The isolation of two strains of tropical typhus from wild rats
    Lewthwaite R, Savoor SR
    Br J Exp Pathol, 1936;17:208.
    (1) Two strains of tropical typhus have been isolated from wild rats trapped in endemic areas.
    (2) Both were isolated and maintained in guinea-pigs.
    (3) One could be isolated in rabbits by the intra-ocular inoculation of virus, and maintained thus indefinitely. The features of this infection appeared to be identical with corresponding infections obtained with the viruses of rural typhus and the tsutsugamushi disease of human origin. Repeated attempts to isolate the other rat strain in rabbits in the same manner failed.
    (4) Rickettsia were found with ease and in abundance in infected material from guinea-pigs infected with either strain, and from rabbits infected with the one-strain.
    (5) The sera of rabbits infected with the two rat strains gave positive Weil-Felix reactions of significant titre.
    (6) Cross-immunity tests in rabbits between one rat strain and six strains of huinan origin of rural typhus and tsutsugamushi showed a cross-immunity to exist, complete in five strains and partial in the sixth strain.
    (7) A concomitant infection with sodoku was present in the guinea-pigs of botlh strains ; although this may have modified the clinical signs, the infection by a typhus virus could be determined by four decisive criteria.
    (8) The conclusion is drawn that the murine origin of the virus of the rural typhus-tsutsugamuslhi group of diseases is now firmly established.
