This study aimed evaluating the effects of cold plasma on the quality attributes of Pacific white shrimp (Litopenaeus vannamei). Shrimp were divided into 4 sample groups: one control and the remaining groups subjected to cold plasma at frequencies of 5, 10, and 15 kHz, respectively, during 10 minutes of application followed by evaluation of chemical, physical, microbiological, and sensorial characteristics. Cold plasma contributed significantly to the maintenance of shrimp quality during storage, delaying the melanization process, microbial growth, improving the physicochemical and sensorial qualities of the samples. Exposure of white shrimp to non-thermal plasma at 15 kHz promoted better physicochemical, microbiological, and sensorial results, and increased the shelf life of samples by 5 days, suggesting that the treatment is effective to preserve the quality of shrimp.

Authors: Lynch Stacy
Published: May 2021

Strategic planning is a process that involves informed dialog among the committee members over a period of time such that a consensus emerges as a natural outcome. In this paper, the multiple factors influencing success of strategic planning has been studied. Key success factors in strategic planning of project management contain such activities that must be performed if the organization intends to achieve its long-term targets. A large majority of enterprises only have a handful of key success factors. Nonetheless, even if one of these success factors is not executed accurately and precisely, the enterprises’ competitive strategy might be threatened. The key success factors in achieving project management excellence also apply to other types of organizations, including those which have not thoroughly implemented their project management systems. Though most organizations are sincere in their efforts to thoroughly implement their systems, stumbling stones are inevitable and have to be overcome. The statistical population of this research is composed of managers, consultants, and experts involved in the strategic planning in project management. According to the research results, the involvement of top management, involvement of team personnel, knowledge of the top management of strategic planning, and organizational culture are the most effective factors of strategic planning.

This study aimed at evaluating the fatty acid profile of meat from feedlot finished heifers and steers fed with high-grain diets. It was used 45 Charolais and Nellore crossbred cattle, 21 of them were heifers with an initial age of 32 ± 2 months and 359.9 ± 6.7 kg of body weight, and 24 were steers with an initial age of 20 ± 2 months and 337.6 ± 6.2 kg of body weight. The animals were distributed in the treatments according to the energy source used in the diet, being them: rice, white oats or corn, using seven heifers and eight steers for each diet. The experimental design was completely randomized, with factorial arrangement 3 x 2 (three treatments and two sexual conditions). The diet based on corn provided higher levels of pentadecylic and margaric fatty acids. Excepting elaidic fatty acid, beef from steers and heifers was similar for the different saturated and monounsaturated fatty acids evaluated. A rice-based diet is advantageous when meat production is recommended with greater participation of fatty acids from the omega-3 group. When finished in feedlot with high-grain diets, the heifers produce meat with higher conjugated linoleic acid (CLA) content and a better ratio between omega-6/omega-3 fatty acids compared to steers. These findings indicate that it is possible to modify undesirable characteristics in meat through the nutritional management of animals, searching for a product that meets the requirements of a modern population, which is redefining its principles regarding food.

The Colombian creole cattle breed Blanco Orejinegro (BON) is an important zoogenetic resource, but there is little knowledge about the genetic parameters and trends of its reproductive traits. Therefore, the aim of this study was to estimate parameters for the reproductive traits calving interval (CI), age at first calving (AFC), gestation duration (GD) and genetic trends for CI in the BON breed. Genealogy information from 7,799 animals was used, and employing the MTDFREML program, the components of the variance, heritability (h2), repeatability (rep), and estimated breeding values (EBV) for CI (n=3308), AFC (n=729), and GD (n=306) were estimated, in addition to the inbreeding coefficient (F) of the population. Genetic trends were established through linear regression using R software. Finally, the animals were classified as inbred (F > 0) and noninbred (F=0), and the effect of inbreeding on reproductive performance was established through a generalized linear model using the R program. An average F value of 4.41%±0.06 was observed. The h2 for CI was 0.11±0.03 with a rep of 0.15±0.04; for AFC, h2 was 0.00±0.05; and for GD, h2 was 0.00±0.08. The genetic trend for CI was -0.01 days/year. Finally, for CI, inbreeding depression was evident; this trait increased when inbreeding increased. These results indicate an important environmental influence on reproductive traits. The heritability estimate for CI suggests that little genetic progress could be achieved through selection. The evidence of inbreeding depression raises the need to control inbreeding to conserve this genetic resource.

This study was developed to examine the effect of combining nitrogen (N) fertilization strategies and pasture management heights on animal and grain production in an Integrated Crop-Livestock System. The experiment was carried out in the municipality of Abelardo Luz - SC, Brazil, between April 2017 and April 2018. A randomized-block design was adopted, with the treatments arranged in a 2×2 factorial arrangement with three replicates. The first factor was the height of the pasture managed under continuous grazing: high (HH, 20 cm) or low (LH, 12 cm). The second factor corresponded to the N application times: in the winter, in the pasture (NP), and in the summer, in the grain crop (NG), in a single N rate of 200 kg ha-1 as topdressing. The forage species used during the pasture phase was black oat (Avena strigosa Schreb), and the pasture was grazed by Nellore × Charolais crossbred steers with an initial body weight of 260 kg. The summer crop was maize (Zea mays). Average daily gain (ADG) and herbage allowance were higher in HH than in LH, whereas animal load was higher in HH. Between the N application times, the animal load was higher in NP. Pasture management height and N fertilization strategy did not affect the variables of number of rows per ear, number of grains per row, thousand-grain weight, or total grain yield, which overall averaged 14,090 kg ha-1. In conclusion, the inversion of nitrogen fertilization between the periods of winter pasture production and grain crop and the management height of the black oat pasture do not compromise the production of maize grains in the summer, or animal production per area. However, steer performance is greater (higher ADG) when the pasture is managed at 20 cm, whereas a high grazing intensity significantly reduces straw on the soil.

Melhoria da Qualidade da Estrutura Interna de Sistemas de Software por Redução do Nível de Acoplamento entre Pacotes
Authors: Pinto Francielli , Costa Heitor
Published: May 2021

Sistemas de software devem possuir alto grau de manutenibilidade para que eles sejam facilmente evoluídos de modo a atender novas necessidades do usuário, corrigir erros ou adaptá-los a novas tecnologias. Uma das características intrínsecas a ser melhorada é a independência modular, em que o software deve apresentar baixo acoplamento e alta coesão. Com as constantes alterações no software, essa característica tende a não ser mais adequada e a estrutura interna do software deteriora-se. O que se pode fazer é realizar refatorações no código para que a estrutura interna readquira essa independência modular. Neste artigo, o objetivo é apresentar uma abordagem para reestruturar os pacotes de sistemas de software, por meio da movimentação de classes entre pacotes, de forma a melhorar a qualidade da sua estrutura interna. A abordagem foi utilizada (i) considerando e (ii) não considerando uma ordem de análise das classes. Cinco sistemas de software foram utilizados para avaliar a abordagem proposta, cujas classes com alto acoplamento e baixa coesão nos pacotes tiveram suas medidas melhoradas e, consequentemente, tiveram melhora na qualidade dos sistemas.

An Empirical Investigation of Maintainability Metrics Adoption in Brazilian Software Companies
Authors: Soares Micael , Romeiro Samuel , Saraiva Juliana , Soares Sérgio
Published: May 2021

Software Maintainability (SM) has been studied since it became globally accepted as part of the software quality model. Many researchers have been proposing a lot of metrics to be used as SM indicators. Nevertheless, the descriptions of these metrics are scattered in a larger number of studies, where many do not explain what these metrics should measure. Therefore, this paper presents a research about SM metrics’ adoption in Brazilian software companies. We performed semi-structured interviews in a face-to-face fashion with 10 software companies resulting in 23 SM metrics listed, and 14 tools for supporting SM metrics collection. Our results showed evidence that most of the SM metrics proposed by researchers are not used by practitioners.

A contratação de serviços de Tecnologia da Informação (TI) pelos órgãos públicos federais brasileiros é uma realidade complexa e requer dos órgãos que esses executem a gestão. Nesse cenário é essencial a utilização de um apoio ferramental que possa auxiliar a gerência da execução do contrato. Recentes diretrizes do governo federal vedam a contratação de fábricas para o desenvolvimento de softwares para atividades meio. Este trabalho tem como objetivo a proposição de um checklist para analisar a adequação das ferramentas de gestão de contratos de acordo com as normas e modelos vigentes. O checklist foi aplicado às ferramentas disponíveis no Portal do Software Público Brasileiro (PSPB). Este estudo foi realizado em quatro fases: desenvolvimento do checklist, a seleção das ferramentas disponíveis no PSPB nas categorias que envolvem gestão, a avaliação das ferramentas selecionadas; e a análise e redação dos resultados. Como resultado, constatou-se que as ferramentas disponíveis no PSPB não atendem às normas e modelos vigentes para a contratação de serviços de TI.

Prozessverträge im Investmentrecht
Authors: Urhahn Alexander Matthias
Published: May 2021

This book answers the question how to implement procedural contracts into the contractual structure of German investment funds. In practice, procedural contracts are primarily concluded where there is already a contractual relationship. The thesis thus analyzes the contractual relations constituting an investment fund. Subsequently, it presents the special requirements the law of investment funds holds for procedural agreements. It thereby shows that the protection for investors under the law of investment funds impacts the validity of procedural contracts. In this manner, the book fills a gap in research and offers numerous insights especially for legal scholars, fund initiators, attorneys and professional investors.
Assistenzsysteme in der Industrie 4.0
Authors: Hofmann Kai
Published: May 2021

The work is dedicated to work in Industry 4.0, a development in which all real processes in the factory are to be digitally recorded and thus automated even more. This brings opportunities for employees, but also threatens de-skilling and comprehensive monitoring.

In labour law, the legal binding force of the humane design of work and human-machine collaboration are therefore being examined. In privacy law the central question is to what extent the efficient organisation of work justifies intensive data processing. To this end, a new approach is presented, which is derived from the interplay of German and European fundamental rights and which differentiates between the two areas of law.
Die Verknüpfung von Nötigungsmittel und Wegnahme in § 249 Abs. 1 StGB
Authors: Marxen Eva-Maria
Published: May 2021

This dissertation examines the link between means of coercion and removal of property as an element that is often decisive to the crime of robbery in the German Criminal Code. In recent case-law, different problematic constellations have centred around this link. The author reviews the legal solutions critically. By analysing the legal structure of the crime of robbery, the author succeeds in conceptualising objective and subjective criteria that can describe the link between the two elements characterising robbery, while providing practical solutions for each case group to legal practitioners and Courts.

Authors: Minamisawa Mayumi
Published: May 2021

This section is focused on the physiological functions of yuzu (Citrus junos) to improve health. The modern lifestyle involves number of modern lifestyles involve various factors that may increase the production of active oxygen species. Nutritional supplements and medicines are commonly utilized to maintain health. Yuzu seeds contain >100-fold the limonoid content of grapefruit seeds and are rich in polyamines (PAs), including putrescine, spermidine, and spermine. Limonoid components mediate the antioxidant properties of citrus. Limonoids and PAs convey various bioactivities. PAs are closely associated with maintaining the function of the intestinal mucosal barrier, which might be involved in the metabolic processes of indigenous intestinal bacteria and in the health of the host. After ingestion, food is digested and absorbed in the intestinal tract, which is also responsible for immune responses against food antigens and intestinal bacteria. Detailed investigations of the physiological functions of extracted yuzu seed extracts may help to develop new treatment strategies against diseases associated with inflammatory responses.

In recent years, Cyber Security threat modeling has been discovered to have the capacity of combatting and mitigating against online threats. In order to minimize the associated risk, these threats need to be modelled with appropriate Intelligent User Interface (IUI) design and consequently the development and evaluation of threat metrics. Artificial Intelligence (AI) has revolutionized every facet of our daily lives and building a responsive Cyber Security Threat Model requires an IUI. The current threat models lack IUI, hence they cannot deliver convenience and efficiency. However, as the User Interface (UI) functionalities and User Experience (UX) continue to increase and deliver more astonishing possibilities, the present threat models lack the predictability capacity thus Machine Learning paradigms must be incorporated. Meanwhile, this deficiency can only be handled through AI-enabled UI that utilizes baseline principles in the design of interfaces for effective Human-Machine Interaction (HMI) with lasting UX. IUI helps developers or designers enhance flexibility, usability, and the relevance of the interaction to improving communication between computer and human. Baseline principles must be applied for developing threat models that will ensure fascinating UI-UX. Application of AI in UI design for Cyber Security Threat Modeling brings about reduction in critical design time and ensures the development of better threat modeling applications and solutions.

Published: May 2021

In electrochemiluminescence (ECL) studies, Tris (bipyridine)ruthenium(II) chloride (Ru(bpy)32+) and its derivatives have been used as primary luminophores since 1972. The flexible solubility in both aqueous and non-aqueous medium and the remarkable intrinsic properties like chemical, optical and desirable electrochemical behavior drives the researcher to use Ru(bpy)32+ and its derivatives as highly active ECL probes in modern analytical science. Novel surface modification of Ru(bpy)32+ based ECL platforms are highly useful in the selective and sensitive detection of biomolecules, DNA analysis, immunoassays detection, and imaging of the biologically important molecules in cells and tissue of living organisms. This chapter discusses and highlights the most significant works in Ru(bpy)32+ based ECL properties of reaction mechanisms and their applications.

Authors: Mili Bhabesh , Chutia Tukheswar
Published: May 2021

Goat is popularly known as ‘poor man’s cow’, rears mostly by the rural people due to better adaptive capability to harsh environment. Heat stress either hot or cold; negatively influence the goat productive and reproductive performance. Both survivability and reproductive performance of goat most often depend on its ability to cope with heat stressor. Goats can rears in a wide range of environment and geography may it be hilly terrain or undulating topography due to cope with the heat stress via combination of behavioral, morphological, physiological, biochemical, metabolic, hormonal and molecular changes at the gene level. All these adaptive mechanisms and genes are important for the assessment of heat stress, adaptability and strategies for management, production of heat-tolerant transgenic goat using advance biotechnological tools for sustainable goat production in challenged environment due to climate change.
Malaria Elimination: The Role and Value of Sero-Surveillance
Authors: Badu Kingsley , Aboagyewa Larbi Amma , Boampong Kwadwo
Published: May 2021

As countries move from intense malaria transmission to low transmission there will be a demand for more sensitive tools and approaches in tracking malaria transmission dynamics. Surveillance tools that are sensitive in tracking real time infectious bites as well as infectious reservoir will be preferred to counting number of cases in the hospital or parasite prevalence. The acquisition and maintenance of anti-malarial antibodies is a direct function of parasite exposure, seroprevalence rates has been used as an efficient tool in assessing malaria endemicity and confirming malaria elimination. Plasmodium antibodies are explicit biomarkers that can be utilised to track parasite exposure over more extensive time spans than microscopy, rapid diagnostic testing or molecular testing and the conventional entomological inoculation rate. Seroprevalence studies can therefore help monitor the impact of malaria control interventions, especially when the parasite occurrence is low. As a result, antibody responses to Anopheles salivary proteins or Plasmodium species may potentially offer reliable information of recent or past exposure; recognise short-term or gradual changes in exposure to Plasmodium infection or to estimate individual-level exposure to infection. This book chapter will present about four studies we have conducted across eastern and western Africa on the efficiency of salivary gland proteins and antimalarial antibodies in tracking malaria transmission intensity. We hope that these could be used as surveillance tools in malaria elimination efforts.

Published: May 2021

Acute Kidney Injury (AKI) is a poor prognosis in hospitalized patients that is associated with high degree of mortality. AKI is also a major risk factor for development of chronic kidney disease. Despite these serious complications associated with AKI there has not been a great amount of progress made over the last half-century. Here we have outlined and provided details on variety of mouse models of AKI. Some of the mouse models of AKI are renal pedicle clamping (ischemia reperfusion injury), Cisplatin induced nephrotoxicity, sepsis (LPS, cecal slurry, and cecal ligation and puncture), folic acid, and rhabdomyolysis. In this chapter we describe in detail the protocols that are used in our laboratories.
Unusual Presentation and Rare Comorbidity of Graves-Basedow’s Disease in Children
Authors: Muzsnai Agota
Published: May 2021

Graves’-Basedow’s disease (GD) is a well-defined hyperthyroid disorder caused by circulating antibodies that results the overproduction of thyroid hormones. All but a few children present with some degree of thyroid gland enlargement and most have two or more signs of excessive thyroid activity, such as tremor, irritability/nervousness, tachycardia etc. Fully developed clinical picture is easy to recognize while often the onset is insidious. Thyroid hormones affect many body systems, so signs and symptoms of Graves’ disease can be wide ranging. A survey on PubMed literature was conducted to gather all published pediatric Graves-Basedow’s cases with unusual presentation at the time of diagnosis. We found all together 70 manuscripts with relevant information from 1978 to 2020 but mainly adult cases. One third of them were found to meet the criteria we focused on and were included in this paper, though in some situation the unusual findings do not consist part of hyperthyroidism, the rare manifestation is only a coexistence, or the serious disease even precedes the GD. Dermatopathy, hepatic dysfunction, impaired fluid balance, concomitant disorders in thyrotoxicosis, tricky laboratory findings, a phenomenon of metamorphic thyroid autoimmunity, peculiarities of thyroid dysfunction in children with Down syndrome, apparent associations, and reconstitution GD are highlighted in this chapter. Awareness about the relation of these remote findings to GD, or frequent coexistence with GD is important for early diagnosis. Finally, a reasonable suspicion for Graves’ disease may ultimately help to prevent unnecessary investigations and treatment.
