Molecular evidence of Rickettsia felis infection in dogs from northern territory, Australia
Sze-Fui Hii, Steven R Kopp, Mary F Thompson, Caroline A O'Leary, Robert L Rees, Rebecca J Traub

Abstract: Rickettsioses are important emerging vector-borne diseases in humans [1], and some have been reported to infect dogs [2,3]. Rickettsioses that are purported to be endemic in Australia include murine typhus (Rickettsia typhi), Queensland tick typhus (Rickettsia australis), Flinders Island spotted fever (Rickettsia honei), scrub typhus (Orientia tsutsugamushi) and Q fever (Coxiella burnetti). Cat flea typhus or flea-borne spotted fever, caused by Ricketsia felis, which was first described in humans in the USA [4], is an emerging zoonosis that has been reported from throughout the world and was recently reported in a cluster of family members in Victoria, Australia [5].The cat flea, Ctenocephalides felis, is a reservoir and biological vector of R. felis [6]. In Australia, R. felis DNA was first identified in fleas in 2006 [7]. Very recently, a molecular study in Australia detected R. felis in 9% of 100 tested Southeast Queensland (SE QLD) pound dogs, suggesting that dogs may act as mammalian reservoir hosts for R. felis [8]. Given the close bond that exists between humans and canines, it is possible that dogs may be a potential source of R. felis infection for humans. Dogs are also important in indigenous community life, and it is therefore prudent to better understand the public health risks that may be associated with the human-animal bond in these communities. To this end, we sought to investigate the prevalence of spotted-fever group organisms in dogs from the indigenous community of Maningrida in the Northern Territory (NT), using PCR assays.Blood samples were collected from 130 dogs undergoing sterilisation facilitated by the Animal Management in Rural and Remote Indigenous Communities (AMRRIC) organisation in the indigenous community of Maningrida, NT. Sixty of these dogs were tested in September 2009 and 70 in September 2010. The sampled cohort of dogs was represented by 56 entire males and 69 entire females. Data on gender were unavailable for 5 dogs. One mL o

Abstract:
Concern over health risk from consumption of bivalves originating from Marudu Bay is escalating due to the rapid agricultural development surrounding the bay. This has motivated us to estimate the health risk index (HRI) of heavy metals from four commercially important and highly exploited bivalve species which are abundant in the bay. Samples (n = 30) of green mussel (Perna viridis), Asiatic hard clam (Meretrix meretrix), Pacific oyster (Crassosstrea gigas) and marsh clam (Polymesoda expans) were acquired from fishermen in Kg. Teritipan, Marudu Bay. These bivalves were analyzed for heavy metals content using the Inductively Couples Plasma-Optical Emission Spectroscopy (ICP-OES). The study found that the mean contents of Arsenic (As) and Manganese (Mn) in all analyzed bivalves exceeded the permissible limits as well as copper (Cu), lead (Pb) and zinc (Zn) in Pacific oyster, and Zn in marsh clam. It was also noticed that consumption of different bivalve species may bring about health risk from different metals as indicated by varied Total Hazard Index (THI) values. Consumption of the four bivalves was noticed to promote high health risk from As intoxication. Although metal pollution index (MPI) analysis revealed that the bivalves from the bay are currently not seriously impacted by heavy metal pollution, vigorous efforts should be taken to preserve the natural condition of the bay for years to come. There are several ways to minimize health issues from bivalve consumption which include keeping the bivalve natural habitat away from heavy metals pollution by strictly enforcing environmental laws and policies, establishing zones for bivalve fisheries, monitoring heavy metals concentration in bivalve on a regular basis and making depuration process a compulsory requirement in every seafood restaurant throughout the country.

Bulletin of Health Research , 2012,
Abstract: Di Sabah, Malaysia telah diadakan survey nyamuk Aedes aegypti dan Aedes albopictus dari bulan Agustus s/d September 1974 dan Maret-April 1975. Survey dilakukan pada 5 daerah di Kudat. Pantai Barat, Pedalaman Sandahan danTawan dengan tujuan untuk melihat distribusi dan density dari kedua jenis nyamuk tsb. Hasil survey menunjukkan bahwa nyamuk A. aegypti telah menyebar pada hampir seluruh daerah pantai Sabah, dan ditemukan hampir pada sebagian besar kotal dan daerah pedesaan di banyak desa. Di bandingkan dengan hasil survey yang pernah dilakukan pada tahun 1970 oleh Ramalingam ternyata terdapat pertambahan 24 persen daerah A. aegypti, dari 58.7 persen daerah A. albopictus selama 4 tahun. A. aegypti sangat biasa terdapat di desa2 pantai sebelah timur, dan ditempat-tempat lainnya menunjukkan Breteau index yang tinggi. Diduga adanya perahu2 dan tempat2 penampungan air merupakan faktor yang penting dalam penyebaran nyamuk. Walaupun tidak terdapat epidemi dengue dan demam berdarah di Sabah, tetapi ada indikasi risiko trahsmissi yang besar di daerah2 dimana Breteau index lebih dari 50. Dari hasil survey ini strategi pemberantasan A. aegypti dapat dikembangkan untuk mencegah terjadinya epidemi dengue dan demam berdarah.

Journal of Educational, Health and Community Psychology , 2013,
Abstract: This study was aimed to investigate the effect of students’ streaming practice in Malaysian secondary on students’ self-esteem through teachers’ expectancy. 17 teachers and 20 students from art and science streams of secondary schools in Penang, Malaysia were participated in this study. Unstructured interviews were used on teachers to collect the qualitative data of teachers’ expectancy. The participating students were from the fourth year of secondary school in Malaysian school system (between 16-17 years old, 10 from science stream and 10 from arts stream) were interviewed in order to collect the qualitative data of teachers’ perceived behavior and self-esteem. Result of this study shown that teachers expected science stream students to have good academic performance but expected arts stream students to be involved in disciplinary problems. Furthermore, science stream students perceived that their teachers were academically supportive but arts stream students perceived that their teachers were focusing on controlling their behavior. On the other hand, findings of this study also revealed that science stream students possed higher level of self-esteem than arts stream students. Accordingly, it was indicated that teachers’ perceived behavior and teachers’ expectancy are correlated to one another, and teachers’ perceived behavior predicts students’ self-esteem. It was discovered that teachers expected science stream students to be eager to improve their academic performance, and students from arts stream class were likely to be involved in disciplinary problems. Students were found to be aware of their teachers’ expectancy, and their perception of teachers’ expectancy affected their self-esteem. While self-esteem was referred to a discrepancy between a student’s ideal-self and actual-self, it was discovered that both groups of students pictured their ideal-self differently to each other. Science stream students pictured their ideal-selves as a character with overall success, while arts stream students pictured their ideal-selves as a socially well-functioned character. Nevertheless, arts stream students found to have lower self-esteem. It was concluded that streaming affected the students’ self-esteem through teachers’ expectancy and perceived behavior.

Open Journal of Anesthesiology (OJAnes) , 2018, DOI: 10.4236/ojanes.2018.83007
Abstract: Swyer-James-MacLeod Syndrome is a rare acquired pulmonary disorder that develops secondary to infectious etiologies in early childhood. Patients who are affected have the potential of developing perioperative respiratory complications. While regional anaesthetic techniques are often performed as adjuncts to general anaesthesia, there is less data on breast operations being done solely under regional anaesthesia. We herein describe a patient with Swyer-James-MacLeod Syndrome who underwent breast lesion wide excision under combined paravertebral and pectoral nerves block, supplemented with propofol infusion for sedation. Choice of blocks was decided upon based on knowledge on the anatomy. Sole regional anaesthetic techniques have been the safest approach in some circumstances and should always be considered in patients who are of high risk under general anaesthesia.
The number of edges on generalizations of Paley graphs
Lawrence Sze
International Journal of Mathematics and Mathematical Sciences , 2001, DOI: 10.1155/s0161171201002071
Abstract: Evans, Pulham, and Sheenan computed the number of complete 4-subgraphs of Paley graphs by counting the number of edges of the subgraph containing only those nodes x for which x and x−1 are quadratic residues. Here we obtain formulae for the number of edges of generalizations of these subgraphs using Gaussian hypergeometric series and elliptic curves. Such formulae are simple in several infinite families, including those studied by Evans, Pulham, and Sheenan.

Abstract: As virus or equipment lost, secret data on mobile phone is facing the danger of leakage. To meet the security needs of mobile platforms,TCG's MPWG has proposed the Mobile Trusted Platform specification,which does not spc cify a particular technical approach to design a Mobile Trusted Module(MTM). Existing research does not provide an o- verall framework of the M`hM, which can actually be used in the smart phone environment, and nor a detailed deploy- ment process of the Trusted Software Stack(TSS) of the framework. A model design on mobile trusted platform for smart phone was proposed in this paper, which combines the pure software MhM based on TrustZone technology with smart card MTM based on Java Card to build two trusted engines. The deployment scheme of trusted computing bases and security analysis of this model were put forward as well.

Fui Fong HO,Hong Kwen BOO
Asia-Pacific Forum on Science Learning and Teaching , 2007,
Abstract: This paper reports on the results of an action research to explore the effectiveness of using cooperative learning strategies on students' academic achievement, their understanding of physics concepts and their motivation to learn in the physics classroom. The study involved a secondary four express physics class of 41 students in a neighbourhood school. Various cooperative learning structures were used to teach the topics on ‘Current Electricity' and ‘D.C. Circuits' over a period of about 8 weeks. During this period, teacher-crafted pre- and post-intervention tests were administered to the class. A questionnaire survey was used to examine students' motivation to learn and perceptions of their learning experiences before and after the treatment period. A class using traditional method of teaching was also involved in the study as a control. The effects of using cooperative learning on students' academic achievement and their motivation to learn were examined through the analysis of the results of the pre- and post-tests and students' perception surveys, while the extent of using cooperative learning on helping students achieve a better understanding of physics concepts was examined through the qualitative analysis of the students' journals. The results showed that the use of cooperative learning does increase students' academic achievement, helps students to achieve a better understanding of physics concepts and increases students' motivation to learn.

Asian Social Science , 2010, DOI: 10.5539/ass.v6n6p119
Abstract: The purpose of this study was to investigate the effects of redundant information in multimedia presentation in history learning. The two modes of multimedia presentation, namely multiple-channel presentation (text + graphics, pictures + redundancy audio, video and animation) and single-channel presentation (text + graphics + pictures) on history learning among deep and surface students were examined. The sample consisted of 240 Form One students from four Malaysian secondary schools. Findings of this study showed that students interacted with the MCP mode obtained significantly higher gain score compared to students interact with the SCP mode. Irrespective of the learning approaches, students using the MCP mode outperformed students using the SCP mode. Apparently, additional redundant information that are relevant to the contents within and across the visual and aural channels provide greater reinforcement in organizing and structuring information issuing in better learning. Results of this study suggest that cognitive load in multimedia-based learning can be minimized if adequate time is provided for comprehension and the pace of learning is under learner control.
