Sara Mechtensimer, Gurpal S Toor
Septic systems can be a potential source of phosphorus (P) in groundwater and contribute to eutrophication in aquatic systems. Our objective was to investigate P transport from two conventional septic systems (drip dispersal and gravel trench) to shallow groundwater. Two new in-situ drainfields (6.1 m long by 0.61 m wide) with a 3.72 m2 infiltrative surface were constructed. The drip dispersal drainfield was constructed by placing 30.5 cm commercial sand on top of natural soil and the gravel trench drainfield was constructed by placing 30...

Since the 1990s, a large body of literature has been published regarding minimally invasive coronary artery bypass grafting. Varying techniques, complexity of the procedures and the necessity of patient selection have led to its inconsistent application. We describe the standardized technique of left internal mammary artery grafting to the left anterior descending coronary artery, off-pump through a left inferior J-hemisternotomy (JOPCAB). This approach is straightforward, safe, effective, and replicable in virtually all patients...

INTRODUCTION: Inguinal hernia repairs are routinely performed as outpatient procedures in most patients, whereas a few require admission due to clinical or social peculiarities. Muscular dystrophies are inherited disorders characterized by progressive muscle wasting and weakness. In case of surgery there is no definite recommendation for either general or regional anesthesia. CASE REPORT: This contribution regards a 48 y. o. male patient diagnosed with Becker Muscular Dystrophy by muscle biopsy 10 years earlier...

BACKGROUND: Increasing demand for non-invasive skin tightening and body contouring procedures has led to several technological in- novations in energy-based devices such as ultrasound, radiofrequency and cryolipolysis. An emerging trend in the eld is to evaluate whether combination therapies for skin laxity/body contouring using energy-based devices can deliver superior clinical results and patient satisfaction. As such, the objective of this prospective, internal-controlled, blind clinical study was to assess the safety and efficacy of cryolipolysis followed by multipolar radiofrequency with pulsed electromagnetic elds (PEMF) and adjustable pulsed suction for the treatment of skin laxity in the flanks...

Sludge dewaterability was chemically and morphologically explored during sewage sludge treatment by vermifiltration. The results, with a conventional biofilter (BF, no earthworms) as a control, demonstrated that the capillary suction time(CST) and specific resistance of filtration(SRF) of vermifilter (VF, with earthworms) treated sludge were 64.9±1.7s and (23.1±1.3)×10(12)m/kg,16.8% and 36.0% lower than that of the BF, respectively. Additionally, the VF could efficiently decompose loosely bound extracellular polymeric substances (LB-EPS), releasing more water trapped inside biofilm...

Culicoides Latreille, 1809 midge species are the putative vectors of Bluetongue virus (BTV) and Schmallenberg virus (SBV) in Europe. To gain a better understanding of the epidemiology of the diseases, basic knowledge about the overwintering of the vectors is needed. Therefore, we investigated culicoid activity in relation to air temperature at livestock stables during late winter and spring season. Ceratopogonids were captured weekly indoors and outdoors on three cattle farms, three horse farms and one sheep farm in the federal state of Brandenburg, Germany between January and May, 2015 by BG-Sentinel UV-light suction traps...

Negative pressure wound therapy (NPWT) consists in applying subatmospheric pressure to a wound that is sealed off by a specially designed dressing and connected by a tube to a suction pump and drainage collection system. Skin defects are extremely common in orthopaedic and trauma surgery. NPWT is valuable across a range of indications. Proven effects include an increase in blood flow, stimulation of angiogenesis, and a decrease in wound surface area. NPWT can be used to treat post-traumatic and surgical wounds, burns, and chronic wounds such as pressure sores and ulcers...

Anaerobic treatment is the most widely used method of waste activated sludge (WAS) stabilization. Using a semi-continuous stirring tank with condensed WAS, we investigated effects of decreasing the solid retention time (SRT) from 32days to 6.4days on sludge reduction, soluble chemical oxygen demand (SCOD) release and dehydration capability, along with anaerobic digestion operated at medium temperature (MT-AD) or anaerobic digestion operated at room temperature (RT-AD). Results showed that effects of temperature on SCOD release were greater at SRT of 32d and 6...

BACKGROUND: Biting midges of the genus Culicoides act as vectors for important diseases affecting humans and both wild and domestic animals. Collection of adult Culicoides specimens in the near vicinity of vertebrate hosts is the major part of any bluetongue surveillance plan. There are old records of Culicoides species dated from 1963, 1968 and 1975. Therefore, it was decided to collect different ceratopogonids members using a light trap. METHODS: One night catching using light traps with a suction fan was performed at representative sites (25 places) located in North Western Provinces (Ardebil, Eastern Azerbaijan, Western Azerbaijan and Zanjan) of Iran (suspected farms for clinical records of Bluetongue virus or serodiagnosis of the Bluetongue virus)...

Laryngomalacia literally means weak larynx. It is the most common cause of noisy breathing in infants and children constituting around 70% of cases. Its aetiology is not clear and various theories are proposed. Treatment remains following the child with regular weight monitoring in view of expected spontaneous resolution. However we cannot predict which child will resolve spontaneously and which child may need surgical intervention. We propose a new theory based on relative imbalance of demand supply of air, suggesting the increase in demand causing turbulent airflow, increasing suction pressure and causing collapse of laryngeal structures...

Thomas Kadyk, David Bruce, Michael Eikerling
This article presents a structure-based modeling approach to optimize gas evolution at an electrolyte-flooded porous electrode. By providing hydrophobic islands as preferential nucleation sites on the surface of the electrode, it is possible to nucleate and grow bubbles outside of the pore space, facilitating their release into the electrolyte. Bubbles that grow at preferential nucleation sites act as a sink for dissolved gas produced in electrode reactions, effectively suctioning it from the electrolyte-filled pores...

BACKGROUND: Ventilator-associated pneumonia is the most prevalent infection in Intensive Care Units, with the highest mortality rate; crude mortality rates may be as high as 20-75%. Many practices such as prevention measures (e.g. hand washing, wearing gloves, suctioning, elevated head of bed between 30° and 45°) have demonstrated an effect of reducing the incidence of this infection. AIMS: To identify the level of nurses' knowledge of ventilator-associated pneumonia and prevention measures before an educational programme, identify the level of nurses' knowledge on ventilator-associated pneumonia and prevention post an educational programme and identify the reasons for not applying ventilator-associated pneumonia prevention measures among nurses in Jordan...
