Non-invasive ventilation (NIV) has been increasingly used over the past decades to avoid endotracheal intubation (ETI) in critical care settings. In selected patients with acute respiratory failure, NIV improves the overall clinical status more rapidly than standard oxygen therapy, avoids ETI and its complications, reduces length of hospital stay, and improves survival. NIV is primarily indicated in respiratory failure due to acute exacerbations of chronic obstructive pulmonary disease, cardiogenic pulmonary oedema and associated with immunocompromised states. Weaker evidence supports its use in other forms of acute hypercapnic and hypoxaemic respiratory failure. Candidates for NIV should be carefully selected taking into consideration the risk factors for NIV failure. Patients on NIV who are unstable or have risk factors for NIV failure should be monitored in an intensive or intermediate care units by experienced personnel to avoid delay when intubation is needed. Stable NIV patients can be monitored on regular wards.

In the modern anesthesia machine, there are various safety checks in place to help prevent the delivery of a hypoxic gas mixture to the patient. They include the pin index safety system (PISS), diameter index safety system (DISS), failsafe valve, oxygen-nitrous oxide proportioning system, oxygen supply failure alarm, flowmeter sequence, and, most distally, the oxygen analyzer. The PISS is a feature in the high-pressure system. The DISS, failsafe valve, and oxygen failure alarm are in the intermediate-pressure system. The flowmeters, proportioning system, and oxygen analyzer are in the low-pressure system. This chapter undertakes a discussion of the distinct role of each feature and their limitations.

This chapter introduces the basics of radiative transfer, which is a primary energy-transport mechanism inside stars, and also contributes to keeping stars ‘inflated’ and balanced against gravity. The roles of opacity and cross-sections in scattering photons are described. With the help of some drastic but still insightful approximations, the luminosity of a star can be related to its mass, and its surface temperature to its interior temperature. Not all types of stars are covered with analytical approximations, and only the simplest cases are studied here: the high-mass main sequence stars where radiation-pressure dominates, and the intermediate mass range that includes the Sun, where gas pressure dominates but convection is not yet important.

The formal organization of court systems and jurisdictional rules established by legislatures often determine which litigants will have their cases reviewed by an appellate court. While some procedural obstacles are straightforward in their application, others require judicial interpretation with research findings suggesting that judges’ policy goals are related to decision-making on threshold issues. Even if there are no jurisdictional constraints, some losing litigants weigh the costs and benefits of pursuing an appeal. Still, filing an appeal does not guarantee full consideration of the issues raised by an appellant. Caseload pressures have contributed to screening procedures that result in only a minority of cases being closely scrutinized by an appellate panel. This chapter examines research on this winnowing process that characterizes litigant access to intermediate appellate courts.

When a person must choose among actions that will affect both him and other people, he generally takes the others’ interests to have some rational weight, but not as much as his own. This familiar view is intermediate between two others: first, that only the individual’s own interests give him reason to act, and, second, that everyone else’s interests count just as much as his own. Of these two polar views, each has had forceful proponents and each can be traced to a compelling starting point. By contrast, the intermediate view that actually informs most practice seems much harder to defend. The question in this paper is whether that view is simply an unprincipled compromise between two powerful but irreconcilable intellectual pressures or whether, instead, there is some positive reason to accept it

Modern assessment of left ventricular (LV) diastolic function should be based on the estimation of degree of LV filling pressure (LVFP), which is the true determinant of symptoms/signs and prognosis in heart failure.In order to achieve this goal, standard Doppler assessment of mitral inflow pattern (E/A ratio, deceleration time, isovolumic relaxation time) should be combined with additional manoeuvres and/or ultrasound tools such as: ◆ Valsalva manoeuvre applied to mitral inflow pattern. ◆ Pulmonary venous flow pattern. ◆ Velocity flow propagation by colour M-mode. ◆ Pulsed wave tissue Doppler of mitral annuls (average of septal and lateral E′ velocity).In intermediate doubtful situations, the two-dimensional determination of left atrial (LA) volume can be diagnostic, since LA enlargement is associated with a chronic increase of LVFP in the absence of mitral valve disease and atrial fibrillation.Some new echocardiographic technologies, such as the speckle tracking-derived LV longitudinal strain and LV torsion, LA strain, and even the three-dimensional determination of LA volumes can be potentially useful to add further information. In particular, the reduction of LV longitudinal strain in patients with LV diastolic dysfunction and normal ejection fraction demonstrates that a subclinical impairment of LV systolic function already exists under these circumstances.

In the chapter, Haq traces the evolution of the World Bank through the decade of the seventies. Since the time the Bank was established, the global political economy structure underwent considerable changes. The World Bank in the 1970s, under the dynamic leadership of Robert Mcnamara, tried to adjust to these changes. The World Bank of the 1980s faced problems of a weak resource base, poor intermediary role and a greater pressure for the Bank to bend its development philosophy towards the private sector. Haq proposes a few structural changes in the Bank that would enable it to overcome these problems.

The chapter analyzes the impact of downstream consumer markets on environmental regime design by explaining why wealthy countries have successfully phased out industrial ozone-depleting substances (ODS) but not an agricultural pesticide known as methyl bromide under the Montreal Protocol, despite the 2005 phase-out deadline for that pesticide. Since the analysis focuses on the regulation of different sectors under the same treaty, it isolates the impact of markets without the threat of major confounding variables interfering with the conclusions. It emphasizes competitive pressures and the structure of intermediate producers in the industrial and agricultural markets employing ODS to explain why methyl bromide has been handled differently from industrial refrigerants. The findings illustrate the impacts of consumer preferences and market competition on the investments of fluoro-product companies and, in turn, on the policies of wealthy countries and rules in the ozone regime.

It is now recognized that cardiovascular disease (CVD) is partly a paediatric problem, i.e. the onset begins in childhood, although clinical symptoms may not become apparent until later in life. Therefore, from a primary prevention point of view, the extent to which physical activity or physical fitness in childhood may deter this process is of utmost importance. Although physical activity and CRF at a young age have not been directly linked to the incidence of CVD, evidence thus far supports cardiovascular health benefits of early higher physical activity and CRF levels on cardiometabolic risk factors like obesity, blood pressure, insulin resistance, and their maintenance throughout the course of life. By affecting these intermediary pathways, lifelong (high-intensity) physical activity may also deter the age-related decreases in CRF and related signs of premature arterial ageing.

This chapter focuses on the relations between the four main stages of de facto authority laid out in this book’s framework, and the respective legitimacy of the international courts (ICs) in question. It also shows that interesting questions about moral legitimacy are brought to light by the transitions from narrow to intermediary and to the extensive and perhaps popular authority of ICs. The chapter then acknowledges that the realities of the development of ICs, and the fascinating ways in which they gain—or sometimes fail to gain—practical authority, put some pressure on established ways of thinking about matters of legitimacy of practical authorities. As in much else in the domain of international law, both the realities on the ground and the theorizing about them are very much works in progress.

Agricultural trade and global food security have been dramatically affected by a series of events. While the global economy is recovering in 2022 from the COVID-19 pandemic, the Russian invasion of Ukraine has sparked new and challenging problems. In a context where agricultural prices were recovering from a generalized surge throughout the pandemic, the war reversed these trends and opened an new episode of rising food prices, general inflationary pressures, and increased volatility. The combination of these shocks affects agricultural trade and food security throughout Africa, especially in countries highly dependent on food imports. The role of trade in creating resilience in this volatile environment is crucial and has been much discussed. From this perspective, the 2022 Africa Agriculture Trade Monitor (AATM) contributes to our understanding of African agricultural trade and its relationship with food and nutrition security in several important ways. First, it provides a thorough analysis of regional and continental trade in agriculture and selected value chains using accurate statistics developed for this report. This year, it adds an analysis of the nutritional content of African trade and looks closely at the trade in processed products. Second, it examines the potentially transformative impact of the African Continental Free Trade Area (AfCFTA) on the region’s economies. Third, at the regional level, it analyzes the evolution of intra- as well as extra-regional trade flows, and trade policy of one of Africa’s Regional Economic Communities (RECs), namely the Economic Community of Central Africa States (ECCAS). As in prior editions, this fifth AATM provides improved trade statistics and uses consistent indicators to monitor trends in Africa’s participation in global trade as well as the status of intra-African trade. The report highlights three main findings. First, the insertion of African countries in global and regional value chains is low but has recently improved. Indeed, both forward participation in value chains (that is, provision of inputs to other countries’ processing sectors) and backward participation (incorporation of imported intermediates into African traded products) have increased, although forward links have grown faster than backward links. Second, intra-African trade increased significantly prior to the pandemic in most RECs, especially in processed products. Yet, this trend was halted by the COVID-19 shock, especially in ECCAS and the Arab Maghreb Union (AMU). Third, the nutritional content of extra-African trade is concentrated in products with a high value and a low caloric content. In comparison, intra-African flows are more intensive in calories, fat, and protein. The report also examines a number of special topics. One chapter is devoted to modeling the impacts on trade, growth, and welfare of several potential approaches to AfCFTA implementation. The results confirm that there is a high opportunity cost associated with weak AfCFTA implementation, which is why it is crucial to take a more ambitious approach that fully liberalizes tariffs and reduces nontariff measures. The 2022 AATM also conducts a detailed analysis of trends and policy issues in value chains for stimulants (cocoa, coffee, and tea), demonstrating that trade in these sectors is still concentrated in unprocessed products. Finally, the report examines in-depth the patterns of trade integration within ECCAS. One important finding is that intraregional trade is still impeded by many tariffs, nontariff measures, and poor transport infrastructure. AKADEMIYA2063 and the International Food Policy Research Institute (IFPRI) are pleased to present this collaborative report, which provides an insightful review of Africa’s progress in trade development, within and beyond the continent, and new analysis on critical topics for trade in Africa’s agrifood sector.
