HAYATI Journal of Biosciences , 2007,
Abstract: Anastatus dasyni Ferr wasp (Hymenoptera: Eupelmidae) is one of the parasitoids attacking eggs of the pepper berry sucking bug, Dasynus piperis China (Hemiptera: Coreidae). Study was conducted in the laboratory to determine immature development, adult longevity, fecundity, sex ratio, oviposition preference, and number of host parasitized. The result showed that immature development time from egg up to adult was 15.57 + 0.09 days, mean fecundity was 99.45 + 5.60 eggs, and sex ratio (% of females) was 67.28 + 0.56%. If provided with honey 10% and host eggs, females lived for 37.7 + 2.78 days and males 6.30 + 0.56 days. Host eggs aged one and two days were more preferred by A. dasyni for oviposition. Mean number of hosts parasitized by this wasp aged less than one day was much lower as compared to the older one.

HAYATI Journal of Biosciences , 2012,
Abstract: Cycad aulacaspis scale (Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae)) is native to Thailand and Vietnam. Since the early 1990s it has been spreading around the world due to the trade in cycad plants for ornamental use. Infestation by this scale can kill cycads in only a few months. Its accidental introduction to Florida endangered the ornamental cycad-growing industry; and in Guam and Taiwan, endemic cycads (Cycas micronesica and C. taitungensis, respectively) are currently threatened with extinction by cycad aulacaspis scale. In November 2011, an introduced scale was discovered damaging cycads in the Bogor Botanic Garden. Samples from Bogor were taken for identification of the scale, and the material was kept for some time to rear out any insect parasitoids that were present. Both the scale insects and parasitoids were prepared on microscope slides and studied microscopically for authoritative identification. The scale was confirmed as A. yasumatsui. The parasitoid Arrhenophagus chionaspidis Aurivillius (Hymenoptera: Encyrtidae) and the hyperparasitoid Signiphora bifasciata Ashmead (Hymenoptera: Signiphoridae) were identified from the samples. Unless immediate remedial measures are taken, several endemic species of cycad in Indonesia may be endangered by infestation by cycad aulacaspis scale.

HAYATI Journal of Biosciences , 2006,
Abstract: Liriomyza sativae is a polyphagous agromyzid leafminer and it has invaded large part of world, i.e Hemiptarsenus varicornis, Gronotoma micromorpha, and Opius dissitus. This research were conducted to investigate progeny, immature development period, longevity of female parasitoids of L. sativae, and to study female parasitoid behaviour in host finding. Host finding behaviour was observed by examining their visit frequency to the leaves that mined by leafminer larvae and healthy leaves. Results showed that H. varicornis produced more progenies (10.70 + 2.58 progenies/female), but not significantly different (P < 0.05) from progenies produced by G. micromorpha (9.90 + 3.81 progenies/female) and O. dissitus (9.60 + 3.31 progenies/female). The immature development period of G. micromorpha (25.65 + 0.38 days) was found to be longer than H. varicornis (16.14 ± 1.20 days) and O. dissitus (14.03 + 0.22 days). Significant different (P = 0.1014) of adult longevity was not found among H. varicornis (9.22 + 2.48 days), G. micromorpha (7.25 + 1.34 days), and O. dissitus (8.74 + 2.18 days). Our analyses also indicated that G. micromorpha and O. dissitus found their hosts based on the larvae mining, however, H. varicornis performed it randomly. Based on the number of progeny and longevity of adult female, all parasitoids tested may have a potential as biological control agents of leafminer, L. sativae.

HAYATI Journal of Biosciences , 2009,
Abstract: During 2008 crop season, an outbreak of severe yellow mosaic disease on yard long bean (Vigna unguiculata subsp. Sesquipedalis) occurred in several farmers’ fields in West Java. Yard long bean var. Parade inoculated manually with extracts from symptomatic leaves showed the symptoms indicating the presence of virus. Symptomatic leaf samples tested positive in enzyme linked immunosorbent assay (ELISA) with antibodies to group specific Potyvirus and Cucumber mosaic virus (CMV). Total RNA derived from symptomatic leaves was subjected to reverse transcription-polymerase chain reaction (RT-PCR) using primers specific to the cylindrical inclusion (CI) protein of potyviruses and CMV coat protein (CP) specific primers. Pair wise comparison of sequences obtained from cloned RT-PCR products with corresponding nucleotide sequences in the GenBank confirmed the presence of Bean common mosaic virus strain Blackeye (BCMV-BlC) and CMV in the symptomatic beans. Sequences of BCMV and CMV isolates from the beans showed maximum nucleotide sequence identities (92-97%) and (90%), respectively with BCMV-BIC and CMV isolates from Taiwan. Each virus isolate also clustered closely with corresponding isolates from Taiwan in a phylogenetic analyses. These results provide first evidence of the occurrence of multiple infection of BCMV-BIC and CMV in the yard long been from Bogor, West Java.

Journal of Geoscience and Environment Protection (GEP) , 2017, DOI: 10.4236/gep.2017.54005
Abstract: This article describes complex geological structure of the region where Metsamor Nuclear Power Plant (MNPP) in Armenia is located. This region of the Lesser Caucasus is characterized by high volcanic activity, tectonic stresses, and movements along the edges of active, highly seismic tectonic blocks. Moreover, this station literally sits on the active tectonic fault of compression type. When construction of the plant commenced, seismic risks were significantly understated. This fact was confirmed by destructive Spitak earthquake with over 25 thousand death tolls. Analysis of intensitys of the earthquakes in the area of the MNPP, their focal mechanisms and risks of movements along active tectonic faults is given in the article. With reference to numerous papers of Armenian, Russian and European researchers regarding seismic hazards and risks in the area of the Nuclear Power Plant, the conclusion about the soonest shutdown and conservation of Metsamor Nuclear Power Plant has been made.
Do health care providers discuss HIV with older female patients?

Abstract: Background: The World Health Organization expressed concern that older people in Africa who are ignored and excluded from HIV-prevention programmes are increasingly being infected with HIV. Studies show an inadequate awareness of the risks of HIV in the older female population. Older women are more susceptible to HIV because menopausal changes, such as vaginal dryness and thinning, increase the risk of HIV infection through tears and abrasions during unprotected sex. Furthermore, progression from HIV to AIDS occurs faster in the older population. Older women need to understand how HIV is transmitted and how it can be prevented in order to protect themselves. It may be postulated that health care providers are reluctant to discuss HIV-related issues with older female patients. The aim of this study was to determine whether older women could recall receiving HIV-related information from health care providers. Methods: This was a prospective cross-sectional study among 100 women, aged 50 to 80, who attended the out-patient section at the Tshwane District Hospital during November and December 2006. Trained research assistants collected data in the patients’ mother tongue. A questionnaire was administered during face-to-face interviews. Results: Only 36% (95% confidence interval [CI]: 26.6% to 45.4%) of the respondents recalled receiving prior information regarding HIV from their health care providers. Of those, 19 (52.78%) said it was in the form of voluntary counselling and testing (VCT), and the remaining 17 (47.22%) received this information during general consultations. There was a statistically significant difference (p = 0.003; odds ratio [OR]: 0.26; 95% CI: 0.09–0.69) between their age stratification of 50 to 59 years and 60 to 80 years with respect to receiving information regarding HIV. In total, 23% of the respondents said they had been tested for HIV and most (n = 19; 82.61%) said they had received counselling. However, it is cause for concern that 17.39% (n = 4) of the respondents who had been tested could not recall receiving counselling. Conclusions: This study shows that older women are neglected regarding the provision of HIV-related information. HIV and its risks to older patients is not routinely part of patient care. VCT seems to be an effective solution. However, there are problems even within the VCT system, since some of the participants claim to have been tested for HIV, without receiving counselling. It is suggested that part of the challenge may lie in the mindset of health care providers. Family physicians need to become proactive in terms of their own practice as well as in terms of their engagement with other health care professionals and students.

Abstract: Asummary of sociological data collected during a socio-dental survey conducted in Quetta District(Balochistan) selected as having fewer than the national average number of persons. Oralconditions were considered under five headings Oral hygiene, periodontal health, dental decay andFluorides Prostheses. It was found that the number of persons having poor oral hygiene, the gumswere un-healthy decayed teeth were present. Dento-facial anomalies were recorded. The cause of missingteeth was assessed with reference to broken teeth or cracked teeth as stated by the subjects. The number ofpersons without dentures decrease with increasing age. The data collected during interviews from adultsindicated that no dental treatment health services were available in the community. An attempt has beenmade in this present Survey to study and report on the dental health the dental services and the attitudestowards dental health and dental services.

The Professional Medical Journal , 2000,
Abstract: This scientific Article throws adequate light on hepatitis and human immuno deficiency virus (HIV)infections in dental patients and is based on actual observations and the experiences of persons havingbiological and clinical knowledge about theses infections. Due to one reason or the other the epidemics ofthese diseases continues to grow. There is a probability that more and more dentists will be treating theinfected persons in future. Because early manifestations of above diseases are often oral, the dentist may bethe first health care provider to identify chances associated with the risk of viral hepatitis and the humanimmunodeficiency virus (HIV) infections. The study is a review on pathogenesis including theimmunological response, spread, prognosis etc and recommendations to control the spread of infections asthese apply to the dental professionals. This article provides an understanding of some concepts involvedin the infection so that future findings and trends can be applied by the endodontist in different clinicalsituations.
