This study was designed to develop monitoring techniques based on aerial survey and to evaluate the effectiveness of control methods for large feral herbivores (especially goats) in the mulga woodlands. It was conducted on a study site in south-western Queensland encompassing Currawinya National Park. Two control programs were undertaken on the park: a ground-based shooting program and a two-stage live-muster and aerial culling program. Population estimates of feral goats based on 100 m strip counts from a fixed-wing aircraft were 4.6/km2 for the survey block for the initial survey with a decline to less than 2/km2 by the end of the project. It was concluded that fixed-wing aerial surveys provide an accurate estimate of the density of large feral herbivores, such as goats. The first control program, based on ground-based shooting, was of only limited success. The second control program, based on contract mustering with the aid of fixed-wing aircraft followed by aerial culling using a helicopter, was very successful in reducing the number of feral goats and other feral animals. This approach represents best practice management of feral goats in the mulga woodlands. The effect of the reduction in goat numbers on goat impact within the park is yet to be evaluated.

Comparative Review

Two Nassella species, Nassella trichotoma and Nassella neesiana, have significantly reduced the carrying capacity of Australia’s south-east rangelands and agricultural systems. It is, therefore, of considerable concern that four other Nassella species have also become naturalised in Australia, and are noted to share many of the ecological features of the two currently widespread species. This paper reviews the distribution, ecology, and impacts of all six Nassella species, which are currently naturalised in Australia, and makes recommendations toward a blanket Nassella control program. The review highlights observed similarities between the species, including the time of flowering, seed type, germination requirements, and growth morphology. These common factors support the possibility that an integrated Nassella control program could be designed to integrate good grazing management with cultural control methods, such as soil cultivation, fire, and native plant competition, with treatments being implemented prior to the common annual seed maturation period. Notwithstanding the success of these integrated programs, it is recognised that seeds of all species may remain viable in the seedbank for up to 12 years, meaning ongoing monitoring and management will be required. To develop even finer control programs, further research into the ecology of these Nassella species is recommended to determine any additional weak spots in these species’ defences, and to subsequently develop and apply novel integrated control methods that target all six species.

Feral Pigs

Eight feral pigs (two boars, four sows and two piglets) were caught in traps using oestrous sows as lures during a control program on a remnant pig population in part of Namadgi National Park during spring, 1990. The program was mostly based on aerial baiting with warfarin. No pigs were caught in traps containing anoestrous sows or in traps containing bait only. Seven unmarked pigs (caught seven days after the cessation of baiting) did not appear to have eaten any warfarin bait. In an earlier pilot trial, two boars were caught at a trap containing an oestrous sow, one of these again in a trap baited only with fermented grain, but no pigs were caught at a trap containing an anoestrous sow. Although not cost-effective as a general technique, this method could be useful in specific circumstances, such as eradication campaigns on islands, if the last few pigs are, or have become bait shy, or are impossible to cull by other methods.

Management Interventions

South African National Parks (SANParks) manage landscapes rather than numbers of elephants (Loxodonta africana) to mitigate the effects that elephants may have on biodiversity, tourism and stakeholder conservation values associated with protected areas. This management philosophy imposes spatial variability of critical resources on elephants. Restoration of such ecological processes through less intensive management predicts a reduction in population growth rates from the eras of intensive management. We collated aerial survey data since 1995 and conducted an aerial total count using a helicopter observation platform during 2015. A minimum of 17 086 elephants were resident in the Kruger National Park (KNP) in 2015, growing at 4.2% per annum over the last generation of elephants (i.e. 12 years), compared to 6.5% annual population growth noted during the intensive management era ending in 1994. This may come from responses of elephants to density and environmental factors manifested through reduced birth rates and increased mortality rates. Authorities should continue to evaluate the demographic responses of elephants to landscape scale interventions directed at restoring the limitation of spatial variance in resource distribution on elephant spatiotemporal dynamics and the consequences that may have for other conservation values.Conservation implications: Conservation managers should continue with surveying elephants in a way that allows the extraction of key variables. Such variables should focus on measures that reflect on how theory predicts elephants should respond to management interventions.

ABSTRACTStrategy DOTS is the tuberculosis control programs. The program has implemented in Tanah Kalikedinding Health Center and has expected to reach CDR ≥ 70% and SR ≥ 85%, which closely related to the management of health centers. This study aimed to evaluate the implementation of the DOTS program in health center whose the results associated with indicators of tuberculosis. This was a descriptive design study with the population was all pulmonary specialist, tuberculosis officers and laboratory personnel and pulmonary tuberculosis patients. The number of Tuberculosis patient respondents was 32 respondents. Samples were chosen using purposive sampling. Data collected by interview questionnaire and checklist. The variables were the finding case, the TB treatment, the enabling factor and inhibiting factor, recording and reporting, and result of tuberculosis indicators. This study resulted that CDR in 2013 was 112% already reached the national target ≥ 70%. This success related to the finding case almost all patients > 2 weeks of cought and all (100%) patients were examinated sputum and diagnosed according to the steps of tuberculosis diagnosis in Indonesia Department of Health guidelines. While SR in 2013 was 65.5% did not reach the target ≥ 85%. It was caused of there are patients who did not have a taking drug observer (PMO). All (100%) patients ever forgot taking anti tuberculosis drugs. Change in schedule of visit to the continuation phase be 2×/month caused patients to forget taking anti tuberculosis drugs. The enabling factor was counseling routinely by health care workers in health center. Inhibiting factor was distance to health center by majority (65,5%) patients were > 1 km. So they needed vehicle to go to the health center. Recording and reporting using electronic systems and being reported by online. So it is expected all TB patients were expected have a taking drug observer and optimizing the role of the a taking drug observer to increase success rate.Keywords: DOTS strategy, Case Detection Rate, Success Rate, evaluation,                     Tuberculosis

AbstractBACKGROUNDUnderstanding pest incursion pathways is critical for preventing new invasions and for stopping the transfer of alleles that reduce the efficacy of local control methods. The mosquitoes Aedes albopictus (Skuse) and Ae. aegypti (Linnaeus) are both highly invasive disease vectors, and through a series of ongoing international incursions are continuing to colonise new regions and spread insecticide resistance alleles among established populations. This study uses high-resolution molecular markers and a set of 241 reference genotypes to trace incursion pathways of Ae. albopictus into mainland Australia, where no successful invasions have yet been observed. We contrast these results with incursion pathways of Ae. aegypti, investigated previously.RESULTSAssignments successful identified China, Japan, Singapore and Taiwan as source locations. Incursion pathways of Ae. albopictus were entirely different to those of Ae. aegypti, despite broad sympatry of these species throughout the Indo-Pacific region. Incursions of Ae. albopictus appeared to have come predominantly along marine routes from key trading locations, while Ae. aegypti was mostly linked to aerial routes from tourism hotspots.CONCLUSIONThese results demonstrate how genomics can help decipher otherwise cryptic incursion pathways. The inclusion of reference genotypes from the Americas may help resolve some unsuccessful assignments. While many congeneric taxa will share common incursion pathways, this study highlights that this is not always the case, and incursion pathways of important taxa should be specifically investigated. Species differences in aerial and marine incursion rates may reflect the efficacy of ongoing control programs such as aircraft disinsection.

Industrial Controller

It is possible to create a control program for a two-mass system based on an industrial micro- controller. The software implements various control methods to reduce the dynamic loads in the kinematic elements during the transients. The methods of simulating the behavior of the mechanism in different condi- tions and time intervals is described, as well as demonstration of the system operation and registration of relevant data. Numerous studies have shown that mechanical vibrations in most cases adversely affect the operation of the electric drive, causing an increase in dynamic loads, which reduces the accuracy of the mechanism, the occurrence of mechanical vibrations that create a dangerous situation. In the transients, when the suspension point of the load moves with acceleration, there is a swing of the load relative to its equilibrium position. The aim of the work is to control the mechanism of horizontal movement by an indus- trial controller, which implements the reduction of loads in the kinematic transmissions during the transi- ents, increases the speed and dampens the oscillations of the suspended load. The task is to develop a control algorithm and demonstrate the possibility of implementing the necessary control laws of the industrial con- troller. The possibility of realization of a microcontroller control of the asynchronous electric drive of the translational movement mechanism with the suspended load is shown, the control algorithm providing re- duction of the dynamic loadings in the kinematic elements is developed, and at small values of a backlash it provides speed and damping of the fluctuations suspended on a flexible thread. The management program is implemented on the basis of the industrial controller. It is possible to demonstrate the operation of the sys- tem in real time, as well as, changing the scale of time, to investigate the dynamic loads arising in the kine- matic elements of the mechanism under different conditions and control methods.

Abstract Analysis for lead and cadmium in biological liquids (blood and urine) is difficult. Results of such analyses from five laboratories are compared for samples with known additions of lead and cadmium. The data, evaluated in terms of inter- and intralaboratory reproducibility and accuracy, suggest that laboratories should voluntarily participate in quality control programs. Users of routine laboratories are advised to use their own quality control program.
