Atmosphere Storage

The development and production of vegetables are increasing in every corner of the globe. Besides fresh and quality vegetables, which are the central pillar of generating economies and business, there is also demand and requirement to differentiate and create post harvest storage, transport, publicity, and preparing the foundation to broaden the utilization of vegetables beyond rising seasons and localities. However, numerous Western nations have created vegetables appropriate for cold environments, including potatoes and tomatoes, to tackle the issue. The countries of tropical areas, like China, India, Brazil, Pan American nations, and nations of Africa, South-East Asia, and Central Asia, have an appropriate environment and assets to cultivate numerous kinds of vegetables. However, the present paper examines the significance of control the atmosphere storage of vegetables and how it affects various foodstuff quality and marketing. The study is based on secondary data. The study systematically reviews many articles, reports and books. The results reveal that the control atmosphere storage enhances the quality of the product that increases the product's suppy and demand. Furthermore, it shows that controlled atmosphere storage is the one most appropriate innovation that can guarantee long storage of vegetables that enhances the freshness and best marketing of the products. The vegetables are kept up through the utilization of explicit CA storage conditions to every product and control of the gas elements, temperature, and relative humidity of the climate. Notwithstanding these components, digestion changes of vegetables have been considered to set up the ideal storage conditions. This is enlarging the improvement of a quick storage system.

The Impact

For system-based auditing to work effectively the auditor will like to rely on internal controls to reduce the volume of substantive testing. It is therefore important for the auditor to examine the internal control practice and procedures that are in place in the client’s business. Where weaknesses are revealed, the auditor recommends ways of improving the systems. This research examines the relationship between some components (risk assessment, control environment and control activate) of internal control systems and the effectiveness of audit program in prudential bank Weija branch. The study exploited information by the help of both primary and secondary data from questionnaires and interview schedules. However, the purposive method of sampling was used in this research work. In all 10 respondents were sampled from the fifty (50) respondents under review. The data captured in this study, was analyzed and interpreted through descriptive method by the help of frequency tables, graphical presentation and tables. Based on the investigations carried, the internal control system was seen to be significant in detection of fraud in banks in Ghana; there is therefore the need for an effective and acceptable internal control structure in banking organizations. It was therefore recommended that Prudential Bank Limited set up internal audit units at their various branches all over the country, so that there shall always be internal audit personnel to ensure adherence to the internal controls that exist in the organization. In view of this, the internal audit personnel should also be revolved at regular intermissions to prevent any form of professional misconducts.

A theoretical model for temperature calculation is presented to understand the tendency of temperature rise during deep surge in a low-speed centrifugal compression system. The one-dimensional aerodynamic equations of unsteady incompressible flow are employed in all components of the system. The equations are suitable to the impeller as well as the stationary parts. The one-dimensional time varied coordinate and control volume approaches for numerical scheme are used in the model. If flow rates in every deep surge cycle are provided from transients calculation or experimental data, the temperature in any position of the system can be evaluated at any step of time. A small low-pressure centrifugal compressor facility for surge experiments is set up. The dynamic measurements for flow and temperature during deep surge are implemented, and the data from measurements can be applied to verify the reliability of present model. Some phenomena can also be discovered from experimental observations. Based on the present experimental and numerical investigations, the characteristics of temperature rise during deep surge are analyzed for different volumes of system and different boundary conditions. Some results are concluded, which are valuable in engineering.

Pittenweem Priory began life as the caput manor of a daughter-house established on May Island by Cluniac monks from Reading (c. 1140). After its sale to St Andrews (c. 1280), the priory transferred ashore. While retaining its traditional name, the ‘Priory of May (alias Pittenweem)’ was subsumed within the Augustinian priory of St Andrews. Its prior was elected from among the canons of the new mother house, but it was many decades before a resident community of canons was set up in Pittenweem. The traditional view, based principally on the ‘non-conventual’ status of the priory reiterated in fifteenth-century documents, is that there was ‘no resident community’ before the priorship of Andrew Forman (1495–1515). Archaeological evidence in Pittenweem, however, indicates that James Kennedy had embarked on significant development of the priory fifty years earlier. This suggests that, when the term ‘non-conventual’ is used in documents emanating from Kennedy's successors (Graham and Scheves), we should interpret it more as an assertion of superiority and control than as a description of realities in the priory.

Most of the discourse on development aid in Africa has been limited to assistance from Western countries and those provided by competing capitalist and socialist blocs during the Cold war era. Japan, a nation with great economic and military capabilities; its development assistance for Africa is encapsulated in the Tokyo International Conference on African Development (TICAD) initiative. The TICAD started in 1993 and Japan has so far held 5 TICAD meetings between 1993 and 2013 during which Africa’s development challenges and Japan’s development assistance to the continent were discussed. The emphasis on “ownership”, “self-help” and “partnership” are major peculiar characteristics of Japan’s development aid that puts the design, implementation and control of development projects under the control of recipient countries. This is a major departure from the usual practice in international development assistance where recipient countries are bound by clauses that somewhat puts the control of development aid in the hands of the granting countries. Such binding clauses have often been described as inimical to the successful administration of the aids and development in recipient countries. Though Japan’s development aid to Africa started only in 1993, by the 2000s, Japan was the topmost donor to Africa. This paper examines the context of Japan’s development aid to Africa by analyzing secondary data sourced from literature and secondary statistics.

In this paper, Linear Quadratic (LQ) optimal control concepts are applied for the active control of vibrations in helicopters. The study is based on an identified dynamic model of the rotor. The vibration effect is captured by suitably augmenting the state vector of the rotor model. Then, Kalman filtering concepts can be used to obtain a real-time estimate of the vibration, which is then fed back to form a suitable compensation signal. This design rationale is derived here starting from a rigorous problem position in an optimal control context. Among other things, this calls for a suitable definition of the performance index, of nonstandard type. The application of these ideas to a test helicopter, by means of computer simulations, shows good performances both in terms of disturbance rejection effectiveness and control effort limitation. The performance of the obtained controller is compared with the one achievable by the so called Higher Harmonic Control (HHC) approach, well known within the helicopter community.

AbstractPorcine reproductive and respiratory syndrome (PRRS) is a serious disease burdening global swine industry. Infection by its etiological agent, PRRS virus (PRRSV), shows a highly restricted tropism of host cells and has been demonstrated to be mediated by an essential scavenger receptor (SR) CD163. CD163 fifth SR cysteine-rich domain (SRCR5) is further proven to play a crucial role during viral infection. Despite intense research, the involvement of CD163 SRCR5 in PRRSV infection remains to be elucidated. In the current study, we prepared recombinant monkey CD163 (moCD163) SRCR5 and human CD163-like homolog (hCD163L1) SRCR8, and determined their crystal structures. After comparison with the previously reported crystal structure of porcine CD163 (pCD163) SRCR5, these structures showed almost identical structural folds but significantly different surface electrostatic potentials. Based on these differences, we carried out mutational research to identify that the charged residue at position 534 in association with the one at position 561 were important for PRRSV-2 infection in vitro. Altogether the current work sheds some light on CD163-mediated PRRSV-2 infection and deepens our understanding of the viral pathogenesis, which will provide clues for prevention and control of PRRS.

AbstractThis article presents a practical project to develop a language policy for an English-Medium-Instruction university in Uzbekistan. Although the university is de facto English-only, it presents a complex language ecology, which in turn has led to confusion and disagreement about language use on campus. The project team investigated the experience, views and attitudes of over a thousand people, including faculty, students, administrative and maintenance staff, in order to arrive at a proposed policy which would serve the whole community, based on the principle of tolerance and pragmatism. After outlining the relevant language and educational context and setting out the methods and approach of the underpinning research project, the article goes on to present the key findings. One of the striking findings was an appetite for control and regulation of language behaviours. Language policies in Higher Education invariably fall down at the implementation stage because of a lack of will to follow through on their principles and their specific guidelines. Language policy in international business on the other hand is characterised by a control stage invariably lacking in language planning in education. Uzbekistan is a polity used to control measures following from policy implementation. The article concludes by suggesting that Higher Education in Central Asia may stand a better chance of seeing through language policies around English-Medium Instruction than, for example, in northern Europe, based on the tension between tolerance on the one hand and control on the other.

Possible trajectories of sustainability are based on different concepts of nature. The article starts out from three trajectories of sustainability (modernization, transformation and control) and reconstructs one characteristic practice for each path with its specific conceptions of nature. The notion that nature provides human societies with relevant ecosystem services is typical of the path of modernization. Nature is reified and monetarized here, with regard to its utility for human societies. Practices of transformation, in contrast, emphasize the intrinsic ethical value of nature. This becomes particularly apparent in discourses on the rights of nature, whose starting point can be found in Latin American indigenous discourses, among others. Control practices such as geoengineering are based on earth-systemic conceptions of nature, in which no distinction is made between natural and social systems. The aim is to control the earth system as a whole in order for human societies to remain viable. Practices of sustainability thus show different ontological understandings of nature (dualistic or monistic) on the one hand and (implicit) ethics and sacralizations (anthropocentric or biocentric) on the other. The three reconstructed natures/cultures have different ontological and ethical affinities and conflict with each other. They are linked to very different knowledge cultures and life-worlds, which answer very differently to the question of what is of value in a society and in nature and how these values ought to be protected.

Background: Sociodemographic data indicate the progressive increase in life expectancy and the prevalence of Alzheimer’s disease (AD). AD is raised as one of the greatest public health problems. Its etiology is twofold: on the one hand, non-modifiable factors and on the other, modifiable. Objective: This study aims to develop a processing framework based on machine learning (ML) and optimization algorithms to study sociodemographic, clinical, and analytical variables, selecting the best combination among them for an accurate discrimination between controls and subjects with major neurocognitive disorder (MNCD). Methods: This research is based on an observational-analytical design. Two research groups were established: MNCD group (n = 46) and control group (n = 38). ML and optimization algorithms were employed to automatically diagnose MNCD. Results: Twelve out of 37 variables were identified in the validation set as the most relevant for MNCD diagnosis. Sensitivity of 100%and specificity of 71%were achieved using a Random Forest classifier. Conclusion: ML is a potential tool for automatic prediction of MNCD which can be applied to relatively small preclinical and clinical data sets. These results can be interpreted to support the influence of the environment on the development of AD.
