Published: March 2023

Heat exchangers and other heat transfer devices/systems play vital roles of heat transfer in thermal fluid flow systems for industrial application. Sodium cooled fast reactors are normally designed to have two loops of sodium coolants and one loop of water coolant which generates steam for power production. The two loops of sodium coolants consist of primary cooling system of sodium which cools the fuel rods of the reactor core and secondary cooling system of sodium transferring heat from the sodium primary cooling system. The water-cooling system transfers heat from the secondary cooling system of sodium for steam generation. Lead cooled fast reactors on the other hand are designed to have primary cooling system of lead cooling the fuel rods in the reactor core and secondary cooling system of water transferring heat from the lead cooling primary system for steam generation. Water cooled Nuclear Power Plants used water to cool the reactor core in the primary system and the heat removed from the core is used for steam generation directly as in BWRs and SCWRs or in the secondary system of heat exchanger as in PWRs. Other reactor systems such as Gas-cooled fast reactor (GFR), Molten-salt reactor (MSR), High-temperature gas-cooled reactor (HTGR), and Small Modular Reactors (SMRs) also have various types of heat exchangers in their designs to support power/electricity generation. Appropriate heat exchangers are therefore needed for various stages of heat transfer in power generation systems. Thus, Heat exchangers and other heat transfer devices/systems play vital roles of heat transfer in thermal fluid flow systems for industrial applications. This study presents brief review of PCHEs which have comparable advantages over other types of heat exchangers. Recent studies on PCHEs and other heat exchanger types have been reviewed. Design and optimization of PCHEs, optimization of Brayton and Rankine circles, and fluid flow and heat transfer devices/systems have been discussed briefly. The review findings show that the design and optimization of PCHEs depends on the intended industrial application of the heat exchanger. The various channel types and channel cross-section types available for design and optimisation as well as the design and optimised system being able to withstand high pressure and temperature conditions in addition to its compact size for the intended industrial application make PCHEs unique among other types of heat exchangers.

Published: March 2023

Bangladesh is a densely populated country and the main food of the country is rice. Although the High Yielding Variety (HYV) Bro rice is being cultivated in almost all areas of Bangladesh it is enormously cultivated in Dinajpur district of Bangladesh. Trend is very important to know the HYV Boro rice yields of the country. Hence the objective of this research is to fit and forecast of trend models of HYV Bro rice yields of Dinajpur district for the year from 1971 to 2007. The regression diagnostics revealed in this study indicate that the data is autocorrelated. Hence the Cochrane-Orcutt method was employed to fit such data set. Finally, we forecasted the yields of the three trend models for HYV Boro rice yields of Dinajpur up to 2021. On basis of the regression diagnostics, the quadratic trend model is an appropriate model for this data set and in this model would be useful for the decision makers for their agriculture and food policy formulation.

Authors: Abedin Md , Shammy Ummoy , Hossain Md
Published: March 2023

This study elucidates the present scenario of poultry litter management practices and development of a technique for safe management of litter at farmer’s level. Survey-based data were collected through pre-tested questionnaires from some purposively selected 42 poultry farms erected within the areas of Mymensingh, Gazipur, Netrokona, and Jamalpur districts. A large amount of poultry litters were generated from broiler and layer farms daily. Most of the farmers dumped this litters in open places (50%) which caused a serious environmental and health hazards. A self-aerated composting technique was designed and developed to effectively manage and mitigate the environmental and health hazards evolving from poultry litters. A compost heap was prepared with rice straw, water hyacinth, and poultry litters with the proportion 1:2:4 respectively by weight at the optimum C:N ratio of 30:1 incorporating the provision for air entraining into the bulk compost heap. Temperature and moisture contents at time interval of three days, and pH, C/N ratio, volume, and microbial properties at time interval of seven days were observed throughout the composting period of 60 days. Analysis was accomplished taking representative samples from the compost heap using the random sampling technique. The quality of compost in terms of nitrogen, phosphorus, potassium, and organic carbon was evaluated in accordance with the Indian and Australian Standards. This technique is found environmentally safe, functional and cost-effective. The developed self-aerated composting technique would be an alternative option for safe management of poultry litters for the farmers in the rural areas.
The Open-Ended Working Group on Reducing Space Threats Through Norms, Rules and Principles of Responsible Behaviours: The Journey so Far, and the Road Ahead
Authors: Azcárate Ortega Almudena , Lagos Koller Hellmut
Published: March 2023

Aware of the critical importance of outer space for humankind, the international community has ascertained the need for a secure and peaceful domain, and has proposed multiple mechanisms to achieve this goal, with varying degrees of success. The United Nations open-ended working group (OEWG) on reducing space threats through norms, rules and principles of responsible behaviours, convened under General Assembly resolution 76/231 is the latest effort to agree on space security mechanisms. With an open and inclusive approach to address the issue of space threats to space systems that brings together perspectives heretofore considered incompatible, this process presents a new chance for the international community to build the common understanding necessary to achieve space security. This article provides insight into the OEWG: how it came to be, its journey so far, and the road ahead.

Space Sustainability Rating in Support of the Development and Adoption of Regulatory Guidelines Related to Long-Term Sustainability
Authors: Rathnasabapathy Minoo , David Emmanuelle
Published: March 2023

In recent decades there has been an exponential increase of activities in space, such that concerns regarding the long-term sustainability (LTS) of the space environment have called to action the need for sustainable and mitigating efforts to ensure that the benefits of space continue to be accessible and beneficial to all. In June 2019, the United Nations (UN) Committee on the Peaceful Uses of Outer Space (COPUOS) adopted twenty-one LTS guidelines. While the guidelines are not legally binding under international law, they reflect the latest global consensus on what responsible and sustainable space activities look like in practice. In parallel, private space actors have led the charge in the development of best practices. Based on sustainability ratings successfully used in other industries, the Space Sustainability Rating (SSR) was first conceptualized in 2016 within the World Economic Forum’s (WEF’s) Global Future Council on Space Technologies as a tool to assess and quantify sustainable design and operational decisions taken by operators. This article provides an overview of the design and development methodology of the SSR, and details how regulatory norms of behaviour and best practices have been incorporated into the SSR, allowing actors the opportunity to demonstrate their adherence to sustainability guidelines.

Safety Zones for Sustainability on the Moon: The Example of the Breaking Ground Trust
Authors: Vertadier Héloïse , Kate Schingler Jessy
Published: March 2023

Although safety zones are not a new concept in international law, their introduction in the context of outer space is fairly recent. First presented as a concept for space activities by the Hague Working Group in 2016, lunar safety zones were formally introduced to the international community through section 11 of the Artemis Accords in 2020. Their compliance to existing international space law and the implications of such zones on the Moon have been heavily debated. Part of this uncertainty lies in the imprecise definition and the lack of clarity regarding their implementation. This article surveys legal precedents for safety zones in other domains, and explores the challenges of those precedents, and open questions surrounding implementation on the Moon. The authors offer a novel legal basis for safety zones with a basis in natural resource management, and discuss the application and implementation of this approach to safety zones focused in particular on instrumenting accountability for sustainable lunar activities. Finally, the Breaking Ground Lunar Resources Trust is presented as a real world case study.

Article: Green Shipping and Trade: Allocating Costs of the IMO Sulphur Regulation 2020
Authors: Singh Abhay , Shanthakumar Sanjeevi
Published: March 2023

In January 2020 the Internatoinal Maritime Organisation (IMO) imposed, down from 3.5% m/m, a new limit of 0.50% m/m Sulphur limit from exhaust gases originating from commercial vessels. This new standard forced the maritime industry to switch to compliant fuels (such as Very Low Sulphur Fuel Oil (VLSFO) and ultra-low sulphur fuel oil (ULSFO) blends) or use an exhaust gas cleaning system (EGCS). Although there may be a consensus that this is a good thing, achievement of benefits has created contractual challenges for the industry. Responsibilities are divided between shipowner and charterer through forming a voyage charter, a time charter, or a bareboat charter (BBC). Baltic and International Maritime Council (BIMCO) and Intertanko provide standard contracts allocating the responsibilities of compliance with IMO Sulphur regulations between shipowner and charterer under the time charter. The compliance obligations under the voyage charterparty and BBC are still unaddressed. Here, we address them and offer an allocation of the responsibility.

Article: A Study of Vietnam’s Double Tax Treaties: Patterns of Treaty Growth and Shifting Treaty Policy
Authors: Pham Loan
Published: March 2023

This article reviews the growth of Vietnam’s tax treaties and shifts in its treaty policies over the thirty-year period since the country created opportunities to attract foreign investment. It follows the incorporation of the Model Tax Treaties of the Organization for Economic Co-operation and Development (OECD) and the United Nations (UN) into its bilateral treaties and considers the limited apparent connection between treaties and foreign direct investment (FDI). A particularly interesting finding is the extent to which Vietnam’s treaties from the outset favoured the use of the UN Model provisions with respect to the definition of permanent establishments (PEs) and capital gains on the disposal of immovable property, particularly in its treaties with OECD members. This is ironic as measures from the OECD Model precedents are more likely to be found in treaties with non-OECD members. Nevertheless, it is clear that the treaties overall favour the allocation of taxing rights to Vietnam as a capital importing jurisdiction. These findings, when considered along with the country’s success at attracting FDI, suggest that developing economies can retain taxing rights and attract foreign investment at the same time.

Authors: Merencia Ana Paula , Lee Huei Diana , Takaki Weber , Spolaôr Newton , Maciel Matheus , Chung Wu Feng
Published: March 2023

Grande parte dos métodos de análise de movimentos do corpo humano não considera as peculiaridades da resposta mecânica corporal em cada plano anatômico. Nesse contexto, sensores inerciais triaxiais, como o acelerômetro, oferecem dados que permitem a análise pormenorizada dos movimentos de articulações e partes do corpo. O objetivo deste trabalho consiste em pesquisar, implementar e analisar três medidas para a comparação de curvas de movimentos do corpo: Dynamic Time Warping, Coeficiente de Determinação R² e Coeficiente de Correlação R de Pearson. Essas três medidas foram analisadas considerando como padrão uma curva de referência extraída de uma base de dados pública com atividades motoras de indivíduos coletadas por acelerômetro. Assim, todas as curvas de movimento da base foram comparadas com esse padrão sob diferentes cenários: (1) dados brutos, (2) dados com normalização, (3) dados com ajuste de curva e (4) dados com normalização seguida de ajuste. Os resultados experimentais indicam que Dynamic Time Warping apresentou melhor desempenho na recuperação de sinais apenas nas abordagens sem ajuste de curva, mas demandou maior custo computacional. Por sua vez, os dois coeficientes levaram a desempenhos competitivos em todos os cenários para a recuperação das três curvas mais similares à referência, exibindo ainda menor custo computacional. Conclui-se que este trabalho cumpriu seu objetivo, sendo as medidas avaliadas promissoras para uso em um sistema original de telemedicina.
TOURISM WEBSITE - TRAVEL BUDDY USING WEB DEVELOPMENT
Authors: Journal IJSREM
Published: March 2023

While the volume of tourist demands dramatically rose, tourism became a common issue. Traditional travel websites often offered broad information or price lists for hotels, transportation tickets, etc. These types of details are no longer sufficient to satiate tourists. Presenting users with unique and imaginative travel itineraries is a challenge for travel websites. This paper presents a new system that aims to produce original journey plans in orderto accomplish this goal. The system relies on software reuse and abstraction approaches. There are three sections to this system (Information Abstraction, Information Reuse, Information Formulation). First, the system needs to abstractly derive the characteristic inquiry into variousjourney components. Second, the system is designed to combine unique aspects from various trip components into a creative travel itinerary. The algorithm then develops a system of measures for creativity to rank the redivided plans according to their ingenuity. Keywords — Travel Website , Abstraction , Reuse , Approaches.

Authors: Somov Anatoly Vladimirovich , Andreev Konstantin Mikhailovich , Roslyakova Natalya Valeryevna
Published: March 2023

The paper deals with the materials of Luzhki II site, which is located in the stepping Volga region on the left side of the Sok River. This memorial was found in 2019. The excavation area of 96 meters was made in 2020. The common collection of artifacts includes 2394 things. The founded materials are from the Neolithic except small group of ceramics (21 fragments) of early middle centuries. The collection of stone inventory includes 568 things. 81 items are implements, they take up about 14,2% of all stone. 1359 things of ceramics were found. The thickness of fragments is from 0,5 to 1,2 sm. Almost all founded rims have a dimple-pearl belt under the cut, which was applied exclusively from the outside. There are four typological groups (without ornament, pinned, comb and ceramics with impression), which show stages of ornament tradition development in the region. A collection of animal bones has been collected, including 412 units. 12 bones have traces of processing or were used as tools. 5 small clay vessels were found in a cultural layer. Two sinkers and one shaft straightener for arrows were found too. According to the available radiocarbon definitions for similar complexes of the forest-steppe Volga region the discovered site could be second half VI middle V thousands BC. The assemblage of pottery from the site reveals the closest analogies in materials from the sites of the developed and late Neolithic of the forest-steppe Volga region, attributed to the Srednevolzhskaya culture.

Published: March 2023

Based on the conducted content analysis of the definition of gamification in educational and non-educational contexts the author defines gamification. The main components of gamification are highlighted and described; they are game mechanics; game dynamics; game aesthetics, social interaction, and game elements. The principles of the implementation of gamification into the educational, organizational and management processes of an educational institution are articulated: the principle of instant feedback; the principle of convergence with interactive technologies; the principle of the fun component importance; the principle of versatility of interactive information users environment; the principle of versatility of the form; the principle of interaction; the principle of the social component importance; the principle of visualization; the principle of the narrative component importance; the principle of content segmentation and gradual complexity of tasks. The features of gamification implementation into the educational sphere are also highlighted, which are important to take into account both in the educational and management aspects. Eventually, the common substantive characteristics of gamification and interactive technologies which are used within the educational sphere have been identified; they are: changing the perception of evaluation procedures used in the learning process; simultaneous consideration of the needs of different education subjects; assistance in developing the reflective and self-evaluative skills of students; boosting the level of motivation of education subjects within the conducting either educational or professional activity, etc.
Developing the motivation to enrich active vocabulary in the process of teaching English to students majoring in Economics
Authors: Kazakova Lyudmila Nikolaevna , Nikitina Svetlana Vyacheslavovna
Published: March 2023

This paper deals with teaching English for Specific Purposes (ESP), focused on the professional training of prospective economists of various fields of activity: managers, accountants, sociologists, specialists in the sphere of economic security. The authors indicate that the most difficult aspect of foreign language for students is the lexical aspect, the problem of enriching the active vocabulary precisely, since being under permanent growing flow of information; the students who already possess basic knowledge are not always motivated to memorize and actively use new lexical units. They prefer using the constructions, words, concepts and terms which they have learned before. It concerns mostly idiomatic expressions and phrasal verbs, which differ in specific semantic characteristics and structure, as well as the complexity of their practical application. However, the use of such structures in speech ensures a successful improvement of a foreign language communicative competence and an integrative approach is proposed for the development and strengthening of motivation in the preparation of methodological textbooks and tasks. It is underlined that when preparing individual stages of the educational course, orientation to the professional use of a foreign language should be taken into account with the analysis of target situations and subsequent consideration of the compliance of tasks and applied forms of work with the needs of prospective economists in specific situations of their professional activities.

Evidence of rehabilitation and the role of risk and protective factors in criminal record screening cases

To limit the collateral consequences of a criminal record, there is increasing attention for ‘evidence of rehabilitation’, which can counterbalance risk factors stemming from a criminal history, for example when assessing requests for a Certificate of Conduct (‘VOG’ in Dutch). Since screening procedures are often regarded as complex, opaque, ambiguous and inconsistent – also by professionals within the criminal justice system – the authors present a first quantitative analysis of the factors that contribute to the chance of successfully winning a Certificate of Conduct in appeal. Our analysis of all published case law since 2004 (N=383) shows that administrative judges in Certificate of Conduct cases mainly refer to risk factors based on the criminal history: the number and seriousness of the offences and the times lapsed. Protective factors and evidence of rehabilitation play only a marginal role. Moreover, in a significant proportion of cases it remains unclear how relevant factors, such as the applicant’s interest, are weighed, if they are referred to at all. This necessitates not only reconsideration of rehabilitation policy, but also more foreseeability, certainty and transparency in criminal record screening decisions.
Francoprovençal: a spatial analysis of ‘partitive articles’ and potential correlates in Swiss and Italian varieties
Authors: Ihsane Tabea , Winistörfer Oliver , Stark Elisabeth
Published: March 2023

In this paper, we focus on partitive articles (PAs), i.e., determiners which, generally, have an indefinite interpretation, and on one of their potential correlates, i.e., invariable de, in Francoprovençal, a non-standardized, highly endangered Gallo-Romance language (cf. Zulato, Kasstan & Nagy 2018), and show the fine-grained spatial distribution of these elements in the Swiss and Aosta Valley (Italy) varieties. Presenting several maps based on fieldwork data from Valais (Switzerland) and the Aosta Valley (Italy), we demonstrate that the spatial distribution of PAs and de is more complex than reported in the literature: we complement the basic subdivision of Francoprovençal into two types, Francoprovençal A and B (cf. Kristol 2014, 2016), with a more nuanced picture, in which the morphosyntactic features of PAs play a crucial role: in Francoprovençal A, the presence of PAs depends on the syntactic context whereas, in Francoprovençal B, their presence is limited mainly to two areas, in which singular and plural PAs do not occur together (one area only has singular PAs whereas the other one only has plural PAs). We also show that there is no correlation between phonologically overt plural marking on nouns and absence of PAs; however, we found a correlation between overt sigmatic number marking on nouns and absence of PAs.
Geographical variation in abdominal colour pattern in Criorhina pachymera (Egger, 1858) (Diptera: Syrphidae)
Authors: Bisschop Jan , de Groot Maarten , Pétremand Gaël
Published: March 2023

The bee-mimicking hoverfly species Criorhina pachymera shows pronounced geographical variation in abdominal colour pattern. Based on 218 records from 22 European countries, we describe six abdomen forms divided over two main groups. Group A in western, northern and central parts of Europe contains abdomen forms A1–A3 with slender pollinose bands on the third and fourth tergite. Group B in south-eastern Europe contains forms B1–B3 with broad pollinose bands. These groups are separated by the Alps and the Carpathians, such as the separation of the original distributions of the two main postglacial recolonization lineages of honey bees in Europe. As these honey bee groups differ by the width of the pollinose bands on the third to fifth tergite, Batesian mimicry can explain the group distribution of C. pachymera with slender or broad pollinose bands. The different forms of C. pachymera in both groups are categorised by the extent of orange colouration on the second and third tergite. The darkest form A1, has a widespread distribution in Europe. Intermediate bright forms A2 and A3 occur predominantly in a belt along the southern margin of the group A distribution and in Sweden. Dark form B1 and intermediate bright form B2 occur on the Balkan peninsula and in neighbouring regions. The brightest form B3, is found in Italy, Switzerland (Ticino) and Greece. There is an average increase in the extent of orange colouration on the second and third tergite with decreasing geographical latitude, making temperature a likely additional cause for the described abdominal colour variation.

Autosomal microsatellite markers allow estimation of expected heterozygosity and allele frequencies which may reveal the effects of genetic isolation, inbreeding, introgression and subdivision within livestock breeds. In the present study, 7 buffalo breeds (Bhadawari, Jaffrabadi, Murrah, Mehsana, Nagpuri, Pandharpuri and Surti) were studied using a panel of eight microsatellite markers selected based on polymorphic information content (PIC) for buffalo (Bubalus bubalis) species as per the guidelines of Food and Agricultural Organization. Frequency of breedspecific alleles was found lower in all the breeds studied; 4 out of 49 alleles showed a frequency of 8% while only one allele showed >10% frequency. In the present study, highest genetic distance was observed between Murrah and Surti (0.896) indicating their isolated breeding over several generations.

Published: March 2023

The study was conducted to evaluate the effect of feeding 5 herbal preparations on the milk yield and composition of crossbred cows. Thirty five lactating cows in their first-third lactation were taken for the experiment. The cows were divided into 7 groups with 5 cows in each group on the basis of average milk yield (8.70±0.08 kg/d). The experiment was conducted for 90 days, partitioned into pre-treatment period (15 days), treatment period (60 days) and post treatment observation period (15 days). The cows in group C0 were not given any supplement and acted as control. In addition to normal routine feeds and fodders, cows in groups T1 and T2 were given either Restobal @ 50ml twice daily for 5 days/month or Ruchamax @ 15 g/ day for 8 days/month, respectively for 60 days treatment period. The cows in groups T3, T4 and T6 were given either Payaboon @ 500 g/ton, Payaboon @ 1 kg/ton, Optrium @ 500 g/ton/ day, respectively for 60 days treatment period. In group T5, cows were given Payapro @ 4 bolus/day for 15 consecutive days commencing after 15 days pre-treatment period. T5 group showed comparatively higher total milk yield than the control and other groups. Average milk yield (kg/d) during the supplementation period was slightly higher in T5 followed by T2 and T6. T5 group showed lowest trend of reduction in milk yield during treatment period. Average milk yield (kg/d) during post supplementation period was also higher in T5. Milk protein and fat (%) were higher in T1 and T3 than the control and other treatment groups. Total solid and SNF (%) showed higher trend in T1. At 15 day of supplementation, milk yield increased in all the treatment groups compared to control (8.38) and it was highest in T5 (9.69). The milk yield decreased gradually thereafter but the rate of reduction was comparatively lower in T24, T5 and T6 than the control. Milk constituents showed significant variations among different weeks in different groups. Hence it can be concluded that herbal preparations can increase the productivity in lactating dairy cows with no deleterious effect on general health.

The aim of the study was to investigate the effect of parity, stage of lactation and udder type on milkability of crossbred dairy cows milked in automated Herringbone milking system. Crossbred cows (218; Karan Fries and Karan Swiss) of different parities, stages of lactation and udder types were milked in 8×2 low-line automated Herringbone milking parlour having automatic cluster removal (ACR) settings for a period of 3 months. The milkablity of cows in automated herringbone milking parlour was based on parameters such as total milk yield, milk yield/session, machineon time, yield first 2 min, and milk flow rates generated automatically in herd management Software during each session of milking. The results showed that milkability of cows was affected significantly based on parity and stage of lactation. The udder types had no effect on milkability except type D (pendulous) udders having least flow rate, which caused increased machine-on time. The overall mean milk flow rates over different intervals during the first two minutes of milking differed significantly in parity and udder types. Similarly, significant differences were observed in the flow rates over different intervals of milking.The milking efficiency benchmarks in terms of cow throughput and milk harvesting efficiency with 2 operators in the milking pit were 69.75±0.57 cows/ h and 305.21±2.75 kg/h, respectively. The operators had idle time during milking in batches of around 4.28 minutes/batch. It can be concluded from the present study that the milkability of crossbred dairy cows was significantly affected by parity, stage of lactation and type of udder in automated Herringbone milking parlour.

Different bio-enhancers commonly used in organic production of various crops were prepared for microbial characterization. Panchagavya had been utilized since long time by the farmers to provide nutrients to the plants and soil micro-organisms. Microbial analysis of bio-enhancers revealed that Panchagavya contained highest number of total bacteria (6.25 × 109 cfu/ml) as compared to Jeevamrita (3.24 × 109 cfu/ml), biodynamic liquid pesticide (2.27 × 109 cfu/ml) and Amritpani (5.49 × 109 cfu/ml). Panchagavya had also higher number of Pseudomonas (4.7 × 109 cfu/ml), Rhizobium (2.43 × 109 cfu/ml), Azotobacter (1.4 × 109 cfu/ml) and Azospirillum (1.03 × 105 cfu/ml). Fungi population was highest in Jeevamrita (1.20 × 107 cfu/ml) as compared to biodynamic liquid pesticide (2.64 × 106 cfu/ml), Amritpani (0.46 × 105 cfu/ml) and Panchagavya (0.20 × 105 cfu/ml). Actinomycetes, Pseudomonas, p-solubilizing microbes, Azotobacter and Azospirillum population were highest in biodynamic liquid pesticide (1.37 × 108, 3.28 × 108, 8.50 × 106, 2.00 × 106 and 1.40 × 105 cfu/ml). Similarly, gram positive bacteria, gram negative bacteria and Rhizobium were highest in Jeevamrita (1.60 × 108, 2.20 × 108, 7.51 × 107 cfu/ml). Amritpani had higher number of actinomycetes (1.31 × 107 cfu/ml), gram negative bacteria (1.35 × 108 cfu/ml) and p-solubilizing microbes (4.80 × 106 cfu/ml). Among all bio-enhancers, Panchagavya was rated most effective bio-enhancer followed by biodynamic liquid pesticide, Jeevamrita and Amritpani. Results reveal that these bio-enhancers could play a potent source of beneficial microbes which could improve soil fertility, crop productivity and produce quality.

The Indian Mackerel is a commercially important fish species and India contributes to world’s 90% of mackerel production. The present study deals with gut content analysis of the Indian Mackerel Rastrelliger kanagurta to determine the type of feed and the feeding habitat. The gonado-somatic index and gastro-somatic indices were determined to find out the spawning period and maturity of the fishes. The stomach emptiness was also calculated to estimate the fish appetite from the stomach content. The present study indicated that Diatoms formed the predominant planktonic feed followed by Dinoflagellates. A total of 25 different types of planktons were found to be preferred by Rastrelliger kanagurta. The gut content also revealed sand particles, fish scales and cnidarian spicules. Highest mean GSI and lowest GaSI were observed in the month of April. The stomach emptiness index revealed gluttonous feeding from November to March and comparatively gluttonous feeding in the month of April. From the present study it can be concluded that Rastrelliger kanagurta, though shows preference for diatoms (40.74%) and dinoflagellates (22.22%), the dietary preference is not limited to it, but they also exhibited preference for Crustaceans (except copepods) (14.81%), Cyanobacteria (7.40%), Copepods (7.40%), molluscs (3.70%) and Protists (3.70%). The present study analysed the food constituents and feeding habitat of the Indian mackerel through gut content analysis. The intensity of feeding was also compared to the size of the fishes, reproductive maturity and the spawning time.

ELECTRIC VEHICLES (EV) are a popular choice for many people looking to reduce their carbon footprint, reduce their reliance on oil, avoid fueling stations, or who just want to own the next step in technology. There are questions, however, about how prepared the United States is for an EV owning populace. Before everyone can own an EV, there needs to be enough infrastructure to support the growing numbers of EVs. This paper will examine the current growth of EVs in Louisiana and use that information to determine if Louisiana has enough infrastructure in place to meet the growing demand.

THERMAL ANALYSIS OF XLPE INSULATED SUBMARINE CABLES FOR DIFFERENT LOADING CONDITIONS
Authors: ARABUL Ahmet Yiğit , KUMRU Celal Fadıl
Published: March 2023

Submarine cables are critical assets that play an indispensable role in interconnected power systems, particularly in cross-sea energy transmission and offshore wind turbines. Their importance is further accentuated in exigent situations such as natural disasters and war, which emphasize the need for secure, reliable and uninterrupted energy supply. Furthermore, the investment and operating costs of submarine cables are relatively higher than other power system equipment, making it essential to operate them under the rated operating conditions to prevent possible faults and ensure power system stability. As thermal stress can lead to damage of cable insulation, it is an essential parameter to consider. Overloading increases thermal stress, resulting in rapid aging of the cable insulation and a shorter cable lifetime. Therefore, it is imperative to determine the maximum conductor temperatures and current carrying capacities of submarine cables under varying loading rates and ambient conditions using thermal analysis. In this study, thermal analyses are carried out for a three-phase, 220 kV HVAC, XLPE insulated submarine cable under different loading conditions. The findings demonstrate that the maximum temperature, current carrying capacity, and total losses of the cable are significantly impacted by loading rate, phase imbalance, and seawater temperature.
Tarifpolitischer Jahresbericht 2022 : Tarifpolitik unter den Bedingungen historisch hoher Inflationsraten
Authors: SCHULTEN THORSTEN ,   WSI-TARIFARCHIV
Published: March 2023

Der aktuelle jährliche Tarifbericht des WSI-Tarifarchivs analysiert die Tarifrunde 2022 und gibt einen detaillierten Überblick zu deren Forderungen und Abschlüssen und den damit erzielten jährlichen Tarifsteigerungen. Im Durchschnitt stiegen die Tariflöhne im Jahr 2022 nominal um 2,7 %. Doch vor dem Hintergrund einer historisch hohen Inflationsrate von 7,9 % mussten die Tarifbeschäftigten letztendlich Reallohnverluste von durchschnittlich 4,8 % hinnehmen. Angesichts der anhaltenden ökonomischen Unsicherheiten und vermutlich weiterhin bestehenden vergleichsweise hohen Inflationserwartungen steht für das Tarifjahr 2023 die Sicherung der Kaufkraft 2023 ganz oben auf der tarifpolitischen Agenda, um hierdurch die private Nachfrage zu erhalten und insgesamt einen Beitrag zur Stabilisierung der ökonomischen Entwicklung zu leisten.
