Published: June 2023

Organic soils are the largest source of GHG emissions in Latvia producing the amount of emissions comparable with the whole energy sector. Organic soils in cropland and grassland alone release about 4.5 mill. tonnes of CO2 eq. annually, which is nearly twice as big as the total emissions from the agriculture sector in Latvia. The reduction of the emissions from the organic soils is the primary target to implement the climate neutrality target in the post-2050 period in LULUCF sector. One of the issues in reporting of GHG emissions from organic soils is different definitions of organic soils, e.g. Latvia is using the Intergovernmental Panel on Climate Change (IPCC) definition (at least 10 cm deep peat layer and at least 12% of carbon content in upper 20 cm of the topsoil), while other countries use different criteria, e.g., at least 30 cm or 40 cm deep peat layer. The scope of this study is evaluating the effect of the peat layer thickness on GHG fluxes in grasslands. The study results proved that increase of the peat layer depth is associated with a trend of increase of CO2 and CH4 emissions. There is also strong correlation between CH4 emissions and the groundwater depth and soil temperature and CO2 emissions. N2O emissions are correlating with nitrogen content in soil. In the study sites soil turns into net source of CH4 emissions if the depth of peat layer exceeds 40 cm. The study results point that the peat depth should be considered as one of the parameters in accounting of GHG emissions.

Holland’s Theory to Guiding Individual Career Choices
Authors: Adlya Soeci Izzati , Zola Nilma 
Published: June 2023

John Holland's theory of vocational personality and work environment is one of the most used, researched, and respected career development theories. Holland believes that a person's choice of a job is a person's expression so that the higher the compatibility between a person's personality and the job one chooses, the higher the level of job satisfaction and stability. But the current reality is that there are individuals who are not given the opportunity to choose and consider experience in their careers, so it is important to introduce Holland's theory to individuals who will prepare to enter the world of work by providing guidance to individuals to understand their personality, the work environment they will be they face and how the two things are related, so that individual career choices are more focused. The method used in this article is a literature review by collecting various reference sources starting from 2018-2022 related to Holland's theory. Holland's theory allows individuals to direct themselves to careers that are in accordance with one's motivation, knowledge, personality, and abilities so that it is expected to reduce problems that have a tendency to arise due to individual incompatibility with work. Therefore, it is important for counselors to be able to understand Holland's theory in order to direct individuals to a career that suits them.

Utility of Machine Learning Technology in Microbial Identification: A Critical Review
Authors: Bharadwaj Alok , Gupta Mansi , Shakya Akanksha 
Published: June 2023

Abstract
Microorganisms are ubiquitous and have far-reaching effects on human life. Since their discovery in the 19th century, microorganisms have fascinated biologists. Microbes play a crucial role in the material and elemental cycles of the natural world. Growing own microbes for research purposes requires a significant time and financial investment. On the other hand, high-throughput sequencing technology cannot advance at the same clip as the culture method. The area of microbiology has made substantial use of machine learning (ML) methods to tackle this problem.
Classification and prediction have emerged as key avenues for advancing microbial community research in computational biology. This research compares the advantages and disadvantages of using different algorithmic approaches in four subfields of microbiology (pathogen and epidemiology; microbial ecology; drug development; microbiome and taxonomy).

Published: June 2023

Heat transfer measurements and high-speed schlieren flow visualization were performed over a cylinder with an aft-attached inflatable decelerator configuration at Mach 3.9. Back wall temperature measurements using thermocouples were used to derive the heat flux distribution over the decelerator surface. A strong nonlinear rise in peak heat flux with angle of attack is observed and windward–leeward effects are quantified. Using appropriate flow and geometric symmetries, heat maps are generated over the regions of the decelerator, which are critical for its thermal design. The effect of fore-end bluntness in terms of peak heat fluxes and integrated heat loads is investigated. The results indicate a possibility of flying at a small angle of attack to reduce the integrated heat loads while simultaneously generating some lift. Tests up to an angle of attack of 20 deg show that even though the peak heating rises strongly, the overall integrated heat loads on the surface of the decelerator remain manageable. A local minimum is seen in peak heat flux levels on the surface at angles of attack of 12–16 deg.
Repatriation as disguised Expulsion in Interwar Belgium
Authors: Zian Yasmina 
Published: June 2023

FR. Dans cet article, j’examine les corrélations entre crise économique, changements de pratiques d’éloignement des étrangers et création de catégories d’indésirables. Pour ce faire, je me penche sur les expériences individuelles des étrangers polonais pour voir comment le rapatriement des étrangers est devenu un moyen d’éloigner les étrangers pour des raisons politiques, alors qu’il était destiné à éloigner les étrangers qui se retrouvaient sans moyens de subsistance à la suite de la crise économique des années 1930. Cette étude se base sur les archives de la Police des étrangers : les dossiers généraux sur le rapatriement des chômeurs et les dossiers individuels des étrangers polonais expulsés. Cette recherche montre que la réponse du gouvernement belge à la crise économique a été, d’une part, une nouvelle utilisation du rapatriement et, d’autre part, la création d’une nouvelle catégorie d’indésirables. NL. In dit artikel bevraag ik de correlaties tussen de economische crisis, veranderingen in de verwijderingspraktijken van vreemdelingen en de creatie van categorieën van ongewenste personen. Daartoe bekijk ik de individuele ervaringen van immigranten om na te gaan hoe hun repatriëring een methode werd om vreemdelingen om politieke redenen te verwijderen, terwijl ze oorspronkelijk bedoeld was om vreemdelingen te verwijderen die als gevolg van de economische crisis van de jaren dertig geen middelen van bestaan meer hadden. Deze studie is gebaseerd op de archieven van de Vreemdelingenpolitie: de algemene dossiers over de repatriëring van werklozen en de individuele dossiers van uitgezette personen. Dit onderzoek toont aan dat het antwoord van de Belgische overheid op de economische crisis enerzijds een nieuw gebruik van repatriëring was en anderzijds de creatie van een nieuwe categorie “ongewenste personen”.
