Saline Water Impact on Water Use Efficiency of Bitter Melon (Momordica charantia L) Using Drip Irrigation

Water shortage is a real problem in many parts of the world and finding alternative solutions such as the application of saline water in cropping systems is highly appreciated. Research on drip irrigation and soil salinity is still inadequate, and their effect on crop yield and water use efficiency (WUE) is a huge challenge for small farmers. The present study was conducted in Malir, a semiarid region in the Sindh province of Pakistan. The purpose was to estimate the effects of two different qualities of irrigation water including fresh quality water (IT1 0.56 dS m−1) and saline groundwater (IT2 2.89 dS m−1) on WUE using drip irrigation technology in 2018–19. The experimental design was complete randomized block design (RCBD) with two treatments of irrigation: (1) freshwater (IT1) with 0.56 dS m−1 electrical conductivity and (2) saline water (IT2) with 2.89 dS m−1 electrical conductivity. The average biomass and crop yield under IT1 were 10.2 t.ha−1 and 7.4 t.ha−1, respectively, and were found higher than those under IT2 (7.3 t−1 and 4.2 t.ha−1, respectively). Hence, both the treatments remained equally effective in season 1 as compared to season 2 ( p ≤ 0.05 ). The WUE of bitter melon under IT1 was 1.60 and 1.56 kg.m−3 in seasons 1 and 2, respectively, and was higher than those under IT2 which were observed 1.21 and 1.07 kg.m−3 in seasons 1 and 2, respectively.

Ten Good Reasons to Practice Neuroultrasound in Critical Care Setting

In the beginning, cerebral ultrasound (US) was not considered feasible because the intact skull was a seemingly impenetrable obstacle. For this reason, obtaining a clear image resolution had been a challenge since the first use of neuroultrasound (NUS) for the assessment of small deep brain structures. However, the improvements in transducer technologies and advances in signal processing have refined the image resolution, and the role of NUS has evolved as an imaging modality for the brain parenchyma within multiple pathologies. This article summarizes ten crucial applications of cerebral ultrasonography for the evaluation and management of neurocritical patients, whose transfer from and to intensive care units poses a real problem to medical care staff. This also encompasses ease of use, low cost, wide acceptance by patients, no radiation risk, and relative independence from movement artifacts. Bedsides, availability and reliability raised the interest of critical care intensivists in using it with increasing frequency. In this mini-review, the usefulness and the advantages of US in the neurocritical care setting are discussed regarding ten aspects to encourage the intensivist physician to practice this important tool.

Psychospiritual impact of COVID-19: Africentric Perspectives

This study sought to find out the psychospiritual impact of COVID-D as a result of the imposition of preventive measures. The study was carried out in the Mezam Division of the North West Region of Cameroon. A mixed research approach was used for the study with the aid of a questionnaire and an interview guide. A convenient sampling technique was chosen for the study based on the availability of the 50 respondents chosen for the study, using the snowball technique. The results of the study reveal that the most acceptable preventive measures that people complied to were personal hygiene (100%), taking of African traditional concoction treatments (100%) and prayers to God (100%). Psychologically, 60% of the respondents expressed symptoms of anxiety, while 30% expressed symptoms for stress and 20% expressed symptoms of depression. Spiritually, all 50 respondents (100%) indicated that their spiritual activities have been disrupted by the pandemic, which poses a real problem for an African oriented society where religion and spiritual activities are common. In conclusions, it was evident that psychospiritual dissonance including mixed and faulty beliefs on those claiming to provide solutions complicated peoples’ understanding of the realities of the situations.

Pasture weed biology and management in Brazil

The livestock production model historically practiced in Brazil has a strong extractive bias, wherein the premise is to produce livestock with absolutely no concern for the preservation or renewal of environmental resources. The absence of technical criteria for the use of pastures has generated low productivity rates, making the activity unsustainable from both economic and environmental points of view. This scenario led the several sectors linked to the production chain to develop a package of strategies to solve the problems faced by livestock farmers. This package of strategies is conventionally called postmodern or corporate farming, in which the extractive process gives way to the business logic of avoiding waste and recovering profit margins mainly through pasture perpetuation. However, there is still a technical gap in corporate cattle farming related to problems caused by pasture weeds because all the concepts applied are derived or copied from concepts generated in agriculture. Furthermore, few researchers have studied or scientific articles written on elucidating the real problem of weeds in livestock production. Thus, the goal of the present review was to present some aspects related to weed ecology, their interference, and management alternatives in pasture areas, thereby collaborating with corporate livestock farming in Brazil because solutions to weed problems are crucial to increase commitment in all sectors of the production chain.

Regeneron and Illumina: a case for (and against) ranges

Insufficiency in patents, especially in emerging and complex technologies, can be a real problem for patent applicants. They are keen to progress to filing for obvious reasons and yet are expected to disclose how the invention works to its fullest extent. Problems arise in cases where a patent claim seeks to reserve a range of some sort. Recent judgments of the English Patents Court and the UK Supreme Court have suggested that this is not a trivial problem in most cases of analysis. The upshot appears to be that a range patent is not to be struck down as insufficient simply because a range exists. Much depends upon the importance of the range to the claim or, in the Illumina case, whether mention or the existence of a range is in any way relevant. An analysis of two recent judgments in the UK concerning sufficiency of disclosure sheds considerable light on the current ambit of legal thinking in this area of patent law.

Applicability of Six Sigma in Human Resource Management

The role of HR has become like that of a firefighter, remembered only in emergencies. Their presence is felt only in their absence. HR is seen as a reactive staff function and a cost centre. The message is clear. Despite its best effort to keep organization together with uniform policy, norms, and values, HR is compelled to prove its financial worth to the organization. HR is under constant pressure for showing their results in quantifiable and financially measurable terms. Introducing Six Sigma in processes of HRM functions seems to be a solution to this problem. However, in some of “Total Six Sigma Organizations,” the human resources department has been practically untouched by Six Sigma. The main reason being the difficulty in quantifying and measuring the financial returns of HR processes. But, some others feel that this is as easy as identifying the gaps and using the right formula. The real problem therefore lies in the perception of an individual HR professional. It takes an HR manager to think statistically and analyze how a process can be quantified.

RAINWATER MANAGEMENT PROBLEMS IN CITIES IN DEVELOPING COUNTRIES: THE CASE OF THE MUNICIPALITY OF ZIGUINCHOR, SENEGAL

Senegalese cities are experiencing very rapid growth in terms of both spatial and demographic development, which has an impact on the management of runoff water, which is increasingly a major concern of authorities and urban populations. In these cities, public sanitation infrastructure is insufficient and unevenly distributed in urban space. The objective of this study is to characterize the problem of rainwater management in the city of Ziguinchor (southern Senegal). The methodology is based on an administration, a questionnaire submitted to 288 heads of households, and an interview guide with 13 actors who stand out in the environmental management component at the local level. The results obtained attest to a real problem of sanitation of rainwater managed in precarious conditions due to the lack of infrastructure and water management methods used by households. The infrastructural problem is a factor in the poor management of rainwater in Ziguinchor, while rainwater drainage practices do not protect the living environment of the populations. In the city of Ziguinchor, the main strategies adopted in the face of the sanitation network deficit are based on backfilling, the laying of sandbags and stones, evacuation through buckets.

Methodology to evaluate school buildings. Educational applications

In this work, an innovative methodology to assess the security, habitability and functionality requirements of school buildings have been designed. The objectives are two: to design an evaluative methodology to assess technically the satisfaction of the basic requirements: safety, habitability and functionality that exist in public school buildings, and apply the methodology developed in university teaching so that students of the disciplines related to construction are able to justify, based on the regulations, their project decisions and intervention. The methodology is developed in the subject Applied Construction of the Master in Architecture of the Rey Juan Carlos University. The main result is that, from the detection of a real problem, such as the state of conservation of school buildings, we can developed an educational practice that helps Master students to ensure that their projects comply with current regulations. One of the most relevant conclusions is that the teaching applications of a real research, offer a provided value at academic level and a realistic view of the current constructions. Furthermore, stress the importance of both planning in accordance with the regulations and ensuring the conservation of the buildings

Successful ASR Prevention in Germany: Influencing Factors and Adequate Measures

Alkali-Silica Reaction (ASR) in concrete pavements has become a real problem in Germany in the end of the 1990s / beginning of the 2000s. In an extensive research project, the background for such ASR-damaging has been examined intensively at the Ruhr University Bochum. ASR in concrete pavements is not only influenced by the reactivity of the aggregate, but rather by a superposition of different influencing factors. For concrete pavements for example, there are specific conditions that increase an ASR significantly. On the one hand, concrete pavements are microstructurally damaged by the superposition of cyclic stresses induced by traffic and climate changes, and on the other hand they are exposed to alkaline de-icing agents during the wintertime. Thereby, an ASR-promoting external alkali supply is given. Three absolute preconditions are necessary for an ASR to occur: potentially reactive aggregates, sufficient supply of alkalis and an adequate degree of moisture. In Germany, there have been numerous measures taken in the last 10 to 15 years in order to prevent ASR-damages in concrete pavements. Already in 2005 the alkali-content (Na₂O-Equivalent) allowed in cements for concrete pavements has been limited to 0.8% by mass. Additionally, in each case the aggregates intended to be used must be assessed beforehand in a special procedure. Since these requirements were established by the highway-authorities in 2005 (with modifications in 2013) there have been no new damages related to ASR observed on concrete pavements, which have been constructed in compliance with these guidelines.
