    An investigation of behavioural patterns that form a basis for termite control in the Australasian region was undertaken using laboratory colonies of the subterranean termite Reticulitermes santonensis (Feytaud). The study attempted to build a picture of the behavioural elements of individuals in a colony and based on this, trophallaxis, aggression and cannibalism were investigated in detail. Preliminary study of food transmission showed that 'workers' played a major role in the distribution of food. It was found, that among factors responsible for release of trophallactic behaviour the presence of 'right odour' between participants was important. It also appeared that the role taken by individuals depended on whether they were hungry or fully fed. Antennal palpation was shown by donors and acceptors alike and this seemed to be excitatory in function. Introduction of aliens into nests elicited aggression and these aliens were often killed. Factors eliciting aggression were investigated and colony odour was found to be important. Further investigations revealed that development of colony odour was governed by genetical and environmental mechanisms. Termite response to injury and death was also governed by odour. In the case of injury either the fresh haemolymph from the wound or some component of the haemolymph evoked cannibalism. Necrophagic behaviour was found to be released by fatty acids found in the corpses. Finally, the response of colonies to nestmates carrying arsenic trioxide was investigated. It was found that living and freshly dead arsenic-carrying nestmates were treated like normal nestmates, resulting in high initial mortality. However, poisoned cadavers soon became repellant and were buried thus preventing further spread of the poison to the rest of the colony. This suggested that complete control of subterranean termites by arsenic trioxide is unlikely to be fully effective, especially in those species which are capable of developing secondary reproductives from survivors and thus rebuilding the community

    Levonorgestrel intrauterine system: A first line medical therapy for idiopathic heavy menstrual bleeding

    Heavy menstrual bleeding or menorrhagia is a common menstrual disorder. Currently, both medical and surgical treatment options are available for the management of heavy menstrual bleeding. Hysterectomy, one of the surgical treatment options is associated with risks and is a costly procedure. Medical treatment may be preferred for the management of heavy menstrual bleeding. Oral medical treatments have various limitations for their use. For instance, cost is a limiting factor for tranexamic acid. Limited data is available to support the effectiveness of oral contraceptives. Poor patient compliance and intolerable adverse events are some other limitations especially in long term use. Levonorgestrel intrauterine system (LNG-IUS) is one of the common medical modalities in the management of heavy menstrual bleeding. LNG-IUS has been compared with other medical options like tranexamic acid, mefenamic acid, combined estrogen-progestogen, or progesterone alone, cyclic oral medroxyprogesterone acetate (MPA) oral norethisterone and low-dose combined oral contraceptive. LNG-IUS is more effective than usual medical treatment and also reduces the effect of heavy menstrual bleeding on quality of life. Similarly, it has shown similar therapeutic effects compared to endometrial ablation. Based on its efficacy, convenience and cost of therapy, it can be considered as the first line medical therapy for the management of heavy menstrual bleeding

    Governance of Open Universities — A Few Observations on Trends in Asia

    No full text
    Like all organisations, good governance is a fundamental requirement for the responsible and accountable management of universities in general and open universities in particular. This is to ensure that these (open) universities remain relevant to their mission of facilitating unfettered access to higher education for citizens and at the same time continue being reliable contributors to personal and institutional developments, the vital ingredients to maintaining sustained national development. While several studies have, in the past, been conducted on governance of universities, almost all of them have centred around conventional, face-to-face institutions. Not much published literature is in evidence on the governance of Open Universities. This paper, drawing from a study on the governance of a few open universities in Asia, tries to discuss the nature of their challenges, and the lessons that can be drawn from their practices and experience. The study focused on aspects relating to institutional autonomies such as curriculum, budgeting and financial management, admission standards, conferment of qualifications, academic staff appointments, development and promotions and research policies. Our findings indicate that, similar to conventional systems, the state plays a crucial role in many aspects of governance both in publicly funded and privately supported institutions. Recent attempts at governance transformation towards greater institutional autonomies is beginning to show limited changes in some but not all jurisdictions studied

    Ocular manifestations in a case of progeroid syndrome

    No full text
    Progeria syndromes are very rare genetic diseases characterized by premature aging changes. There are several phenotypes and variables noted in literature in some cases difficult to specifically classify a specific syndrome. It occurs due to mutation in DNA repair genes. The most common ocular findings are loss of eyebrow and eyelashes, brow ptosis, lid margin changes, entropion, Meibomian gland dysfunction, severe dry eye, corneal opacity, cataract, poor mydriasis, and rod-cone dystrophy. We report this case with all the above ocular manifestations in 19year old teenager with additional finding being retinal detachment

    ROER4D Sub-project 1 - Indonesia OER review

    No full text
    The ROER4D project endeavours to cover at least three regions in the Global South, namely, South America, Sub-Saharan Africa, and South and South East Asia. However, background information on OER projects, policies and research and information on infrastructural, legal, socio-cultural and/or economic factors that might influence the adoption of OER in post-secondary education in these regions is incomplete despite the work of current projects. The project will provide background information on infrastructural, legal, socio-cultural and/or economic factors that might influence the adoption of OER in post-secondary education for the researchers involved in the ROER4D sub-projects and the final ROER4D meta-analysis. This desktop review aims to provide an overview of OER projects, policies and research in Indonesia as of the period 2013-2014
