Reservoirs are built to store water during abundance for possible reuse during scarcity; sediment incursion is the leading phenomenon that limit reservoirs to sustain this function. Therefore, modelling the rate at which reservoir accumulates sediments is critical in understanding the nature of the problem, the time frame within which it is expected to occur, and the best mitigation strategy that will maintain the reservoir service. This study investigated the sediment influx in three typical Sahelian reservoirs in Kano state using the bathymetric method. The reservoir capacities were found to be declining at different rates but with grave consequences on the future, and economy of the state. In prolific terms, the state is losing 490 million litres of water storage each year. Presently, Magaga lost 39% of its capacity; Thomas has lost 13%; while Kafin-chiri has lost 5%. For sustainability, this trend needs to be addressed. The short and long-term best management strategies to curtail this trend have been outlined in this study.

At Alamán’s initiative a law of 1830 established the Banco de Avío, a government-funded development bank for the spurring of industrialization, especially in the textile sector, with which his name has forever been associated. His views of industrialization as a development strategy as opposed to a renewed reliance upon silver mining are discussed, as well as the short- and long-term effects of loans made to textile entrepreneurs and the cronyism employed by Alamán both in organizing the Banco itself and in allotting its capital as loans to industrialists. The state of the textile industry in Mexico before and after the Banco is described.

AbstractNeonates are exposed to repetitive pain and stress during their stay in a NICU, which can lead to chronic complications related to their neurodevelopment and neurobehavior. Approximately 20 percent of all neonates in a NICU are intubated, mechanically ventilated, and require suctioning, which can cause both acute and chronic pain. Pain management in the neonate can be challenging. Nurses and other caregivers need to be well trained to assess pain in the neonate to effectively identify and provide appropriate pain management strategies. There is a lack of evidence to support routine administration of opiates in the neonate. As with any medication, the possibility of short- and long-term adverse reactions must be considered. Nonpharmacologic therapy should be used as much as possible.

Most of the Northeast Atlantic stocks are currently fished above the biological reference points (e.g., Fmax). In attempting to achieve such targets, advisers and managers have faced two main problems. First, it is impractical to (i) simultaneously maximize yields, stabilize fisheries, and safeguard stocks and (ii) optimize both short- and long-term outcomes for the industry. Second is the lack of predictability, several years ahead, in factors influencing decisions. This study addresses these twin issues by exploring the relative performances of various multiannual and compromise (or composite) management strategies. Multiannual fishing efforts are set in advance for a ``resolution'' period of several years, at the end of which they are updated. They are calculated to satisfy a prior weighted compromise amongst three criteria: (i) minimizing fishing effort variability, (ii) minimizing catch variability, and (iii) reaching a ``mobile target:'' the latter is defined with a second weighted compromise between the long-term target and the fishing effort at the beginning of the resolution period. A safe and optimal balance between all the short- and long-term fishery outcomes is found with a 5-year resolution period, during which the mobile target is split into 40-60% of the long-term target, and 60-40% of the fishing effort at the start of the resolution period, while criteria i, ii, and iii are weighted equally.

Objectives The purpose of this article is to describe and develop the predictive value of three models during the COVID-19 epidemic in Chile, providing knowledge for decision-making in health. Methods We developed three models during the epidemic: a discrete model to predict the maximum burden on the health system in a short time frame—a basic SEIR (susceptible-exposed-infected-removed) model with discrete equations; a stochastic SEIR model with the Monte Carlo method; and a Gompertz-type model for metropolitan city of Santiago. Results The maximum potential burden model has been useful throughout the monitoring of the epidemic, providing an upper bound for the number of cases, intensive care unit occupancy, and deaths. Deterministic and stochastic SEIR models were very useful in predicting the rise of cases and the peak and onset of case decline; however, they lost utility in the current situation due to the asynchronous recruitment of cases in the regions and the persistence of a strong endemic. The Gompertz model had a better fit in the decline since it best captures the epidemic curve’s asymmetry in Santiago. Conclusions The models have shown great utility in monitoring the epidemic in Chile, with different objectives in different epidemic stages. They have complemented empirical indicators such as reported cases, fatality, deaths, and others, making it possible to predict situations of interest and visualization of the short and long-term local behavior of this pandemic.

One of the eternal influencing factors on the development of people´s place of living is the problem of burying. These problems change in time but consequentially require long-term planning, the reservation of an area in a proper territorial community with all planned consequences thoroughly thought through. Cemeteries come close to the course of life in society and its relationship to the values of previous generations. According to the state of the cemetery and its tidiness it is possible to make a judgement on the cultural advancement of society. The loss of rituals and the encroaching secularization of society are connected to making the problems of burials and burying taboo. The objective of this work is an attempt to change this state by leading a discussion on the tradition of burying as part of life in the European context of selected cemeteries in Vienna, Brno and Prague. There are taken into consideration the historical influences and the reasons of introducing legal arrangements, historical connections, urban establishments, funereal arts, architecture and pictures of the cemeteries that were studied. There are observed the present trends in burying and the arrangement of existing cemeteries and comparing them with inter-European influences. The problems of cemeteries are presented with their projection into the future on the cultural and ethical level of the moral code.

The application of advanced endovascular techniques in very complex femoropopliteal atherosclerotic lesions has shown to expose patients to a higher risk of distal embolization (DE). This complication can affect both the short- and long-term outcomes, leading to worsening ischemia, early minor/major amputation, and longer hospital stay. Recently, there has been an increasing body of evidence on pathophysiology and clinical–radiological management of DE that however has not been systematically addressed by guidelines. The aim of this review was to analyze the current evidence outlining definition and classification, risk assessment, prevention, and management strategies of DE in femoropopliteal endovascular interventions.

Marketing in general can have greater influence if a new, yet old, perspective on marketing is adopted—something akin to the original orientation of marketing. Adopting George Fisk’s definition of marketing and marrying it with notions derived from the institutional economist Karl Polanyi is proposed. The histories of marketing thought and of institutional economics are reviewed to demonstrate their affinity and similar origins. Fisk’s conceptualization of marketing as societies’ provisioning systems is shown to correspond with Polanyi’s conceptualization of economies as instituted processes, admitting more than the market and the state as ways economies have historically and cross-culturally integrated with society. The obsolete marketing mentality is that marketers, including macromarketers, are overly fixated on the market and ignore or overlook alternatives. The Fisk/Polanyi orientation will attract macromarketers interested in marketing and development, critical marketing, sustainability, alternative economies, and those interested in the long-term prospects of macromarketing. Adopting this old, but new, framework will connect the past with the future, permit macromarketers make a mark on a larger intellectual landscape and serve to invite scholars in this larger landscape to engage with macromarketing.

Antiretroviral therapy (ART) and Caesarean section (CS) delivery significantly reduce the risk of vertically transmitted HIV infection. Attention must focus on determining the optimal management strategy for HIV-positive pregnancies. Guidelines must reflect not only the activity and tolerability of combination ART in pregnancy for mother and infant and the potential short and long-term infant toxicity, but also whether surgical delivery can confer an added benefit if combination ART had reduced plasma viraemia to undetectable levels. To aid the development of management strategies for the Republic of Ireland, a retrospective detailed review of all HIV-positive pregnancies since the introduction of combination ART was undertaken. Since 1997 there have been 25 deliveries to 24 women. Combination ART reduced plasma viraemia to undetectable levels in 76% mothers at delivery. The CS rate was 28% and no unanticipated infant toxicity was encountered. To date no infant has proven infected. Three infants have seroreverted and 24 of 26 infants have had at least 2 negative HIV ribonucleic acid (RNA) and polymerase chain reaction (PCR) tests. Two infants are less than one month old. In this study, the CS rate of 28% is below that reported from many centres yet no vertical transmission was found. Given the efficacy of ART in reducing plasma viraemia, the additional benefit of CS for these women is questionable.
