Agricultural practices, if not managed correctly, can have a negative impact on receiving environments via waste disposal and discharge. In this study, a chicken slaughter facility on the rural outskirts of Sydney, Australia, has been identified as a possible source of persistent effluent discharge into a peri-urban catchment. Questions surrounding the facility's environmental management practices go back more than four decades. Despite there having never been a definitive determination of the facility's impact on local stream water quality, the New South Wales Environment Protection Authority (NSW EPA) has implemented numerous pollution reduction requirements to manage noise and water pollution at the slaughter facility...

Uranium (U) is a chemo-toxic, radiotoxic and even a carcinogenic element. Due to its radioactivity, the effects of U on humans health have been extensively investigated. Prolonged U exposure may cause kidney disease and cancer. The geological distribution of U radionuclides is still a great concern for human health. Uranium in groundwater, frequently used as drinking water, and general environmental pollution with U raise concerns about the potential public health problem in several areas of Asia. The particular paleo-geological hallmark of India and other Southern Asiatic regions enhances the risk of U pollution in rural and urban communities...

Transient nasolacrimal duct obstruction secondary to a mass lesion compressing the sac or sac-duct junction is rare. We report a case of a young female who presented to us with complaints of watering and a mass lesion in the lacrimal sac region. An organized perilacrimal mass filled with thick pultaceous material was noted during surgery. Following the drainage of the mass lesion, irrigation of the lacrimal system was freely patent. Microbiological examination and DNA sequencing targeting interspacer region was suggestive of Pleurostomophora richardsiae species...

BACKGROUND: Transurethral intracorporeal lithotripsy is the modality of choice for the endoscopic disintegration of large, long-standing, radiolucent or high-density stones. Despite several advantages and proven benefits of contact ureterolithotripsy/ureterolithoextraction (CULT), the application of irrigation carries significant risks of untoward perioperative events including retrograde stone migration and postoperative pyelonephritis. METHODS: We describe a new technique - endoscopic intracorporeal lithotripsy in the gas (СО2) medium...

The phylloplane is the first contact surface between Theobroma cacao and the fungus Moniliophthora perniciosa, which causes witches' broom disease (WBD). We evaluated the index of short glandular trichomes (SGTs) in the cacao phylloplane and the effect of irrigation on the disease index of cacao genotypes with/without resistance to WBD, and identified proteins present in the phylloplane. The resistant and susceptible genotype CCN51 and Catongo presented a mean index of 1600 and 700 SGTs•cm-2, respectively...

BACKGROUND: Stagnant flooding, where water of 25-50 cm remains until harvest time, is a major problem in rainfed lowland areas. Most of the Sub1 varieties, which can withstand around 2 weeks of complete submergence, perform poorly in these conditions. Hence, varieties tolerant of stagnant flooding are essential. RESULTS: This paper presents the first study to map QTLs associated with tolerance to stagnant flooding, along with a parallel study under normal irrigation, using an F7 mapping population consisting of 148 RILs derived from a cross of Ciherang-Sub1 and the stagnant-flooding tolerant line IR10F365...

Waterlogging, one of the notorious abiotic stressors, retards the growth of apple plants and reduces their production. Thus, it is an urgent agenda for scientists to identify the suitable remedies for this problem. In the current study, we found that melatonin significantly improved the tolerance of apple seedlings against waterlogging stress. This was indicated by the reduced chlorosis and wilting of the seedlings after melatonin applications either by leaf spray or root irrigation. The mechanisms involve in that melatonin functions to maintain aerobic respiration, preserves photosynthesis and reduces oxidative damage of the plants which are under waterlogging stress...

INTRODUCTION: Left atrial pulmonary vein isolation (PVI) is an accepted treatment option for patients with symptomatic atrial fibrillation (AF). This procedure can be complicated by stroke or silent cerebral embolism. Online measurement of microembolic signals (MESs) by transcranial Doppler (TCD) may be useful for characterizing thromboembolic burden during PVI. In this prospective multicenter trial, we investigated the burden, characteristics, and composition of MES during left atrial catheter ablation using a variety of catheter technologies...

As a principle of resource-oriented sanitation practice, urine should be separated from the source and utilized for other purposes such as producing fertilizer. This is because urine is rich in nutrients; therefore, sending it directly to wastewater treatment plants causes problems in the regular treatment process. The addition of solid additives such as powdered rice straw can help with harvesting nutrients from urine. In this study, the procedure and efficiency of using powdered rice straw for nutrient harvesting were investigated by tracking the reductions in ammonia, phosphate, magnesium, and calcium ions, and the harvested nutrients were identified using crystallography methods...

Carp are a highly successful invasive fish species, now widespread, abundant and considered a pest in south-eastern Australia. To date, most management effort has been directed at reducing abundances of adult fish, with little consideration of population growth through reproduction. Environmental water allocations are now an important option for the rehabilitation of aquatic ecosystems, particularly in the Murray-Darling Basin. As carp respond to flows, there is concern that environmental watering may cause floodplain inundation and provide access to spawning habitats subsequently causing unwanted population increase...

Pot-based phenotyping of drought response sometimes maintains suboptimal soil water content by applying high-frequency deficit irrigation (HFDI). We examined the effect of this treatment on water and abscisic acid (ABA) relations of two species (Helianthus annuus and Populus nigra). Suboptimal soil water content was maintained by frequent irrigation, and compared with the effects of withholding water and with adequate irrigation. At the same average whole-pot soil moisture, frequent irrigation resulted in larger soil water content gradients, lower root and xylem ABA concentrations ([X-ABA]), along with higher transpiration rates or stomatal conductance, compared with plants from which water was withheld...

Geoengineering, the deliberate large-scale manipulation of earth's energy balance to counteract global warming, is an attractive proposition for sparsely populated deserts. We use the BNU and UVic Earth system models to simulate the effects of irrigating deserts under the RCP8.5 scenario. Previous studies focused on increasing desert albedo to reduce global warming; in contrast we examine how extending afforestation and ecological projects, that successfully improve regional environments, fair for geoengineering purposes...
