Abstract:

The intake of natural water or waste water from a depth exceeding the suction height of centrifugal pumps is mainly carried out due to additional water supply at the suction of the pump. However, this process becomes more complicated if it is necessary to purify water from mechanical impurities. The purpose of the presented work is to consider this issue based on the development and study of the parameters of an ejector water intake treatment plant equipped with a pressure-vacuum hydrocyclone. The main contribution of the ongoing research is the establishment of the technological parameters of

Abstract:

This article presents a reconstruction plan for an underground water deferrization station in southern of Tyumen Oblast, including a feasibility study. The reconstruction is necessary due to unsatisfactory water quality delivered to consumers, primarily high manganese content. Analysis of the initial and treated water quality from the existing plant revealed key factors affecting the treatment processes. The proposed technological modifications consider the groundwater’s unique composition, in particular, the high dissolved carbon dioxide leading to low pH, along with the operational experienc

Abstract:

The article describes a new structural and technological scheme of a thermal vacuum extruder, where chambers for preliminary and final dehydration of the finished product interact with each other by means of an ejector. The steam pumped out of the final dehydration chamber by means of a vacuum pump moves to the high-pressure part of the ejector and is removed outside for regeneration of the thermal energy spent on machine technological process. Simultaneously, this air flow ensures the steam movement from preliminary dehydration chamber of the extruder to the low-pressure part of the ejector.

In order to achieve an efficient and economical advanced drinking water system, the relationship between operating conditions, membrane filtration flux and water qualities was examined by using a pilot plant consisting of ozonation facility, ozone resistant microfiltration (MF) module and granular activated carbon (GAC) tower.

(Uploaded by Plazi for the Bat Literature Project) The fruit-bat Rousettus aegyptiacus (Pteropodidae) in Israel consumes a variety of cultivated and wild fruits.

The feeding roosts of the fruit-bat are located an average of 30 m from its feeding trees and thus the bats disperse the seeds away from the shade of the parent canopy. The bat spits out large seeds but may pass some (2%) of the small seeds «4 mg) through its digestive tract. However, neither the deposited seeds nor the

Heart failure (HF) is a significant global healthcare burden with increasing prevalence and high morbidity and mortality rates. The diagnosis and management of HF are closely tied to ejection fraction (EF), a crucial parameter for evaluating disease severity and determining treatment plans.

ABSTRACT Planetary systems with sufficiently small orbital spacings can experience planetary mergers and ejections. The branching ratio of mergers versus ejections depends sensitively on the treatment of planetary close encounters.

We apply both smoothed particle hydrodynamics and N-body integrations to investigate the fluid effects in close encounters between gas giants and the long-term evolution of closely packed planetary systems.

Abstract:

The plant-infecting geminiviruses encapsidate their single-stranded DNA genome in characteristic twinned particles that are unique among viruses. These particles are formed by joining two incomplete T=1 icosahedra. African cassava mosaic virions were purified by density-gradient centrifugation from infected Nicotiana benthamiana plants and analysed for their stability with respect to pH changes and heat treatment by using electron microscopy. Negative staining and rotary shadowing revealed stable virions as well as isolated capsomeres between pH 4.0 and 8.5. At pH 9.0 and above, particles disi

Abstract:

Background and Clinical Significance: Heart failure and kidney diseases often coexist and are difficult to clinically manage. Dysfunction in either organ exacerbates dysfunction in the other, potentially leading to cardiorenal syndrome (CRS). CRS has five different subtypes, with CRS type 5 being the most problematic given that it consists of an acute insult superimposed upon chronic CRS. Additionally, type 5 CRS can be complicated by heart failure-related cardiogenic shock (HF-CS), which is associated with increased hospitalizations and has a high 1-year mortality rate.

Abstract:

Transthoracic and transesophageal echocardiography are important investigations in the intensive care unit (ICU) to diagnose acute cardiac pathologies and assess the haemodynamic status. Recommendations for critical care echocardiography (CCE) have been published recently, but these still lack an evidence-based foundation. It is not known if performing transthoracic echocardiography (TTE) on a routine basis instead of only when required in acute cases is feasible or clinically useful. In this single-centre prospective observational study, we routinely performed TTE on 111 consecutive non-cardi

Abstract:

Right ventricular (RV) function is an important determinant of prognosis in congenital heart diseases, pulmonary hypertension, and heart failure. Preventive sildenafil treatment has been shown to enhance systolic RV function and improve exercise capacity in a model of fixed RV pressure load. However, it is unknown whether sildenafil has beneficial effects when treatment is started in established RV dysfunction, which is clinically more relevant. Our aim was to assess the effects of sildenafil treatment on RV function and fibrosis in a model of established RV dysfunction due to fixed afterload.

Owing to strong stellar feedback, only ∼L⋆ haloes retain a baryon mass $\gtrsim\! 50\hbox{ per cent}$ of their cosmic budget.

This study aimed to establish an inoculation method based on ascospore ejection from naturally infected leaves and use it to assess the response to T. nubilosa of eucalypt species and interspecific hybrids.
