Glomerular filtration, the first step leading to the formation of primitive urine, is a passive phenomenon. The composition of this primitive urine is the consequence of the ultrafiltration of plasma depending on renal blood flow, on hydrostatic pressure of glomerular capillary, and on glomerular coefficient of ultrafiltration. Glomerular filtration rate (GFR) can be precisely measured by the calculation of the clearance of freely filtrated exogenous substances that are neither metabolized nor reabsorbed nor secreted by tubules: its mean value is 125 mL/min/1.73 m² in men and 110 mL/min/1.73 m

Abstract:
Nanofluids have recently been considered as one of the most popular working fluid in heat transfer and fluid mechanics. Accurate estimation of thermophysical properties of nanofluids is required for the investigation of their heat transfer performance. Thermal conductivity coefficient, convective heat transfer coefficient, and viscosity are some the most important thermophysical properties that directly influence on the application of nanofluids. The aim of the present chapter is to develop and validate artificial neural networks (ANNs) to estimate these thermophysical properties with acceptable accuracy. Some simple and easy measurable parameters including type of nanoparticle and base fluid, temperature and pressure, size and concentration of nanoparticles, etc. are used as independent variables of the ANN approaches. The predictive performance of the developed ANN approaches is validated with both experimental data and available empirical correlations. Various statistical indices including mean square errors (MSE), root mean square errors (RMSE), average absolute relative deviation percent (AARD%), and regression coefficient (R2) are used for numerical evaluation of accuracy of the developed ANN models. Results confirm that the developed ANN models can be regarded as a practical tool for studying the behavior of those industrial applications, which have nanofluids as operating fluid.

Abstract:
The IV and V group transition metals borides, carbides, and nitrides are widely known as ultra-high temperature ceramics (UHTCs), owing to their high melting point above 2500°C. These ceramics possess outstanding physical and engineering properties, such as high hardness and strength, low electrical resistivity and good chemical inertness which make them suitable structural materials for applications under high heat fluxes. Potential applications include aerospace manufacturing; for example sharp leading edge parts on hypersonic atmospheric re-entry vehicles, rocket nozzles, and scramjet components, where operating temperatures can exceed 3000°C. The extremely high melting point and the low self-diffusion coefficient make these ceramics very difficult to sinter to full density: temperatures above 2000°C and the application of pressure are necessary conditions. However these processing parameters lead to coarse microstructures, with mean grain size of the order of 20 µm and trapped porosity, all features which prevent the achievement of the full potential of the thermo-mechanical properties of UHTCs. Several activities have been performed in order to decrease the severity of the processing conditions of UHTCs introducing sintering additives, such as metals, nitrides, carbides or silicides. In general the addition of such secondary phases does decrease the sintering temperature, but some additives have some drawbacks, especially during use at high temperature, owing to their softening and the following loss of integrity of the material. In this chapter, composites based on borides and carbides of Zr, Hf and Ta were produced with addition of MoSi2 or TaSi2. These silicides were selected as sintering aids owing to their high melting point (>2100°C), their ductility above 1000°C and their capability to increase the oxidation resistance. The microstructure of fully dense hot pressed UHTCs containing 15 vol% of MoSi2 or TaSi2, was characterized by x-ray diffraction, scanning, and transmission electron microscopy. Based on microstructural features detected by TEM, thermodynamical calculations, and the available phase diagrams, a densification mechanism for these composites is proposed. The mechanical properties, namely hardness, fracture toughness, Young’s modulus and flexural strength at room and high temperature, were measured and compared to the properties of other ultra-high temperature ceramics produced with other sintering additives. Further, the microstructural findings were used to furnish possible explanations for the excellent high temperature performances of these composites.

Abstract:
The earth's atmosphere is divided into four layers: the troposphere, stratosphere, mesosphere, and thermosphere (figure 4.1). These layers are defined by alternating decreases and increases in air temperature with height. The boundaries between the layers are called the tropopause, stratopause, and mesopause. The troposphere, the lowest layer of the atmosphere, supports life on the planet and is the layer in which “weather” occurs. It extends about 7 mi (11 km) above sea level and is characterized by a mean temperature decrease with height (—ΔT/ Δz) of about 3.5°F per 1000 ft, or 6.5°C per km. This decrease explains the lower temperatures encountered at higher elevations in the mountains. Although the mean temperature decreases with height in the troposphere, the atmospheric structure, particularly at the base of the troposphere, varies significantly over time as the earth warms during the day and cools at night, as the seasons change, and as weather systems move through the atmosphere. The vertical structure of the atmosphere is characterized by an exponential decrease in air density and pressure with height. Air density is the mass per unit volume of the atmosphere as expressed, for example, in kilograms per cubic meter or pounds per cubic foot. Air pressure is the force exerted on a unit area by the weight of the air molecules above the measurement point as expressed, for example, in millibars or pounds per square inch. Air pressure at any given level is thus a measurement of the weight of a column of air above that level. Although there is no "edge" to the earth's atmosphere, approximately 99.9% of the air molecules (and therefore the weight of the atmosphere) are found below 31 mi (50 km). Temperature, density, and pressure are interrelated, so that a change in one will result in changes in the other two. The mathematical description of this relationship is called the gas law (appendix A). The gas law allows any one of these variables to be calculated if values for the other two variables are known.

Abstract:
The scientific work presents a detailed analysis of the 17-19 years young men morphofunctional status screening studies. The young men who took part in the research did not have any pathologies in their health and belonged to the main medical group. To effectively address the goal of the study, a wide range of methods typical of researches in the field of physical culture and sports was used. A total of 34 indicators were studied, including 23 direct measurements. The reliability of the obtained results is confirmed by adequate theoretical substantiation of scientific positions and research apparatus, highly informative and reliable research methods, optimal duration, correctness of processing, analysis and interpretation of the obtained data. The relevance of the chosen topic is confirmed by the results of the study, which were based on knowledge of age anatomy, age physiology, hygiene of physical culture and sports. Analysis of the young men morphological condition individual results in pre-conscription age indicates incomplete formation of the musculoskeletal system, and the circumferential size of the waist and hips, which exceeded physiological norms indicate the presence of excess body weight. There is a significant asymmetry between the results of wrist dynamometry, the difference between the strength of the right hand and the left hand is 6.2 kg. Studies of the body composition revealed that the average group performance of muscle and bone components of the young men aged 17-19 years is below the physiological norm. The range of muscle component values ranges from a minimum of 36.2% to a maximum of 78.7%, indicating sample heterogeneity. Studies of cardiovascular parameters revealed: heart rate at rest, which exceeded the physiological norm in 26.3% of test subjects, signs of bradycardia in 7.6% of test subjects, signs of hypotension were found in 4.7% of test subjects, signs of hypertension were found in 18.4% of test subjects. We found 7.6% of young men with the pulse pressure exceeded the permissible threshold. The vast majority, which is 70.7% of the studied young men of pre-conscription age, had individual results of endurance coefficient in the range of 17-29 s.u., which indicates a weakened activity of the cardiovascular system. Low individual indicators of lung vital capacity are observed at 8.3% of young men, and are in the range of 2.6-2.9 l. 10.1% of young men with individual respiratory rate results significantly higher than the age norm were also found. In the course of the study, we found that only 19.1% of pre-conscription youth had individual results of the hypoxia index which corresponded to the age norm. The individual results of the Rufier test in pre-conscription young men were distributed as follows: 7.9% have above average level of physical working capacity, 37.2% have average level of physical working capacity, 42.3% have satisfactory level, 12.6% have low level of physical working capacity. It should be noted that as a result of the study we did not find any young men who would have a high level of physical capacity.

Abstract:
Pulse on time, pulse frequency, peak current, and base current are the important parameters to be optimized in pulsed current tungsten inert gas (PCTIG) welding of Al–SiC metal matrix composite. Experiments were designed and conducted using the L9 orthogonal array technique. The regression equation was developed using Design Expert® statistical software package to predict the weld center’s micro hardness, yield strength, ultimate strength, elongation (%), bending load, weld depth, weld width, cooling rate, and peak temperature near the weld zone of Al-8% SiC composite, welded using PCTIG welding. Correlation coefficient shows 0.9 for all the mechanical properties. This showed that the regression equation and the mathematical model developed were adequate. Analysis of contour plot, interaction effect, signal-to-noise ratio, and mean response were developed, the influence of each pulsed current parameter was evaluated at each level, and the percentage of influence was calculated by using pulsed current parameters. Ultimate tensile strength and bending load values depend on the microstructure. When the cooling rate is higher, fine microstructures are observed due to grain refinement; higher tensile strength and bending load are also observed. Due to the decreased cooling rate, coarse microstructures are observed, which result in poor tensile strength and bending load. PCTIG welding parameters are responsible for the change in the cooling rate of the weld zone. The optimization of the PCTIG welding parameters shows that the peak current and base current should be 160 and 60 A, respectively. Pulse on time is recommended to be 50%–55% and pulse frequency to be 5 Hz.

Abstract:
Acute kidney injury is a serious condition, occurring in up to two-thirds of intensive care unit patients, and 8.8-55% of patients with acute cardiac conditions. Renal replacement therapy is used in about 1.5-15% of intensive care unit patients. The term cardiorenal syndrome refers to combined heart and kidney failure; three types of acute cardiorenal syndrome have been described: acute cardiorenal syndrome or cardiorenal syndrome type 1, acute renocardiac syndrome or cardiorenal syndrome type 3, and acute cardiorenal syndrome type 5 (cardiac and renal injury secondary to a third entity such as sepsis). Acute kidney injury replaced the previously used term 'acute renal failure' and comprises the entire spectrum of the disease, from small changes in function to the requirement of renal replacement therapy. Not only failure, but also minor and less severe decreases, in kidney function are of clinical significance both in the short and long-term. The most recent definition for acute kidney injury is proposed by the Kidney Disease: Improving Global Outcomes clinical practice guidelines workgroup. This definition is a modification of the RIFLE and AKIN definitions and staging criteria, and it stages patients according to changes in the urine output and serum creatinine (see Tables 68.1 and 68.2). Acute kidney injury is a heterogeneous syndrome with different and multiple aetiologies, often with several insults occurring in the same individual. The underlying processes include nephrotoxicity, and neurohormonal, haemodynamic, autoimmune, and inflammatory abnormalities. The most frequent cause for acute kidney injury in intensive cardiac care patients are low cardiac output with an impaired kidney perfusion (cardiogenic shock) and/or a marked increase in venous pressure (acute decompensated heart failure). Predictors for acute kidney injury in these patients include: baseline renal dysfunction, diabetes, anaemia, and hypertension, as well as the administration of high doses of diuretics. In the intensive cardiac care unit, attention must be paid to the prevention of acute kidney injury: monitoring of high-risk patients, prompt resuscitation, maintenance of an adequate mean arterial pressure, cardiac output, and intravascular volume (avoidance of both fluid overload and hypovolaemia), as well as the avoidance or protection against nephrotoxic agents. The treatment of acute kidney injury focuses on the treatment of the underlying aetiology, supportive care, and avoiding further injury from nephrotoxic agents. More specific therapies have not yet demonstrated efficacy. Renal replacement therapy is indicated in life-threatening changes in fluid, electrolyte, and acid-base balance, but there are also arguments for more early initiation.

Abstract:
Mental health social work is a broad, rather than a rigorous, church. Since the 1980s social workers have gained in professional status by the introduction of the roles of the approved social worker (or licensed to carry out civil commitment in the American context), care co-ordinators, managers of managed care facilities, or psychotherapists. These gains have come at a price outlined in the text above. Often the cost of closer collaboration within the multi-disciplinary framework has led to the risk of giving up the attempt to hold on to, and further develop, an alternative and complimentary perspective from that of psychiatrists, nurses, or psychologists, as well as raising doubts as to the uniqueness of MHSW. The increased narrowness of the role is not simply the byproduct of the legal framework. It is also due to increased specialization within mental health on the one hand, and the effects of neo- liberal policies globally on public sector funding on the other hand. The move to privately contracted work, either in managed care or in psychotherapy so apparent in the United States, is yet another outcome of neo-liberal policies which fragments MHSW. As a trend we are likely to see growing beyond the United States, the increased concentration of mental health social workers within the private sector does not bode well for a profession whose value base focuses on the need to protect the more vulnerable and stigmatized populations, and to provide the dual perspectives of psychosocial input. Mainly due to governmental pressure related to fear of risk and its potential political fallout, the focus on working exclusively with people experiencing long-term severe mental illness has contributed to the increasing narrowness of the role of social workers in most First World countries. The paralleled withdrawal of social work involvement with people who have milder forms of mental distress within public sector and not-for-profit services, and its increased availability only to those who can afford it, is a reflection of this situation. The core qualities of belief, optimism, and caring of MHSWs identified in a cross-national research coupled with the ability of MHSW to innovate as highlighted in this chapter, illustrate the optimistic scenario for positive change within this branch of social work. However, unless theory building and research aspects are given the importance they deserve within MHSW globally, including an inevitable critical dimension of the existing system, mental health social work is likely to be no more than a reflection of the developments in other professions. This will not only mean curtailing its autonomous potential, but also the impoverishment of the multi-disciplinary framework as a whole of a crucial dimension necessary for its comprehensive work, as exemplified in some recent work on the social aspects of MHSW. In addition, mental health social work will have to develop a much stronger policy making function, if it is to provide a more responsive, effective, and comprehensive service to users, relatives, and the communities in which these people live.

Abstract:
In order to minimize the number of iterations to a turbine design, reasonable choices of the key parameters must be made at the earliest possible opportunity. The choice of blade loading is of particular concern in the low pressure (LP) turbine of civil aero engines, where the use of high-lift blades is widespread. This paper presents an analytical mean-line design study for a repeating-stage, axial-flow Low Pressure (LP) turbine. The problem of how to measure blade loading is first addressed. The analysis demonstrates that the Zweifel coefficient [1] is not a reasonable gauge of blade loading

Abstract:
Impact pressure due to plunging breaking waves impinging on a simplified model structure was investigated in the laboratory based on two breaking wave conditions: the wall impingement wave condition and the deck impingement wave condition. Pressure, void fraction, and velocities were measured at various locations on the deck surface. Impact pressure was correlated with the mean kinetic energy calculated based on the measured mean velocities and void fraction to obtain the impact coefficient. For the wall impingement wave condition, the relationship between impact pressure and mean kinetic ener

Abstract:
Supercritical pressure water has been widely used in many industrial fields, such as fossil-fired power plants and nuclear reactors because mainly of its high thermal efficiencies. Although many empirical correlations for heat transfer coefficients of supercritical pressure water have been proposed by different authors based on different experimental data base, there exist remarkable discrepancies between the predicted heat transfer coefficients of different correlations under even the same condition. Heat transfer correlations with good prediction performance are of considerable significance

Abstract:
In this work a uniquely designed air-water bubbly flow heat transfer experiment is accomplished to investigate the characteristics of pressure drop of airflow and heat transfer between water and tubes for its potential application in evaporative cooling. The attempts to reduce the pressure drop at the condition of maintaining higher heat transfer coefficient have been done by decreasing the bubble layer thickness though the water pump circulation. Pressure drops of air passing through the sieve plate and the bubbling layer are measured for different heights of bubble layer, hole area ratio of

The specimens have been inserted in an open-circuit type wind channel with rectangular cross section. The effect of the foam core height on the heat transfer has been analysed by imposing three constant heat flow rates at the bottom plate of the samples: 250, 325 and 400 W and varying the air mass velocity between 0.005

Abstract:
Based on flat plate results, mean velocity and friction coefficient estimation methods are proposed for rough surface turbulent boundary layers on axial compressor and turbine blades. The ratio of the displacement thickness to boundary layer thickness (δ*/δ) was first suggested by Zagarola and Smits (1998) for smooth pipe flows. The same parameter is proposed in this paper to scale the normalized mean velocity defect of smooth and rough surface flat plate turbulent boundary layers with zero, favorable, and adverse pressure gradients.

Abstract Energy consumption prediction plays an important role in pipeline operation regulation and energy management. Accurate energy consumption prediction is helpful to make important decisions, including unit commitment, batch scheduling, load dispatching, energy consumption target setting, etc. The energy consumption of crude oil pipeline is mainly the electrical energy of pump unit. The average annual electrical energy consumption of China’s crude oil pipelines accounts for more than half of the annual operating cost of pipelines.

<p>Catenary domes are a less conventional, but structurally efficient, alternative to traditional circular-profile domes. Unlike the more common circular forms, there is a dearth of wind loading information for catenary structures. This paper aims to provide some insight in this regard. A series of wind tunnel tests were undertaken to investigate the effects of geometry and Reynolds number on the mean pressure coefficient distributions over catenary domes in a turbulent boundary layer flow. A hemispherical dome was also assessed, and the results compared with that for the catenary shapes
