Spurensuche am Strand. Forschendes Lernen an der Küste
Authors: Blaseio Beate
Published: August 2023

„Wer nach einem Spaziergang am Meer ohne die Taschen voller Steine und Muscheln zurückkommt, war gar nicht am Meer.“ Dieser Spruch unbekannter Herkunft verweist darauf, dass das Sammeln am Strand eine Tätigkeit ist, die von vielen Küstenbesucher*innen intuitiv vorgenommen wird. Die geographische Spurensuche an der Küste kann im Sachunterricht bildungswirksam eingesetzt werden, wenn das Finden, Bestimmen und Hinterfragen natürlicher und anthropogener Dinge in den Ansatz des Forschenden Lernens eingebettet wird.

Alimentación y nutrición de mujeres y niños en el mundo romano (siglos II a.n.e.-III n.e.)
Authors:   , Spicoli Marianela Ivana
Published: August 2023

Esta tesis aporta una interpretación alternativa a la del análisis histórico actual sobre la alimentación y la nutrición de mujeres y niños en el mundo romano (II a.n.e.-III n.e.). En lugar del enfoque tradicional centrado en los determinantes sociales y culturales, la nutrición se considera aquí como el resultado de la interacción entre los distintos elementos que operaban en la vida cotidiana de las mujeres y los niños: las actividades que realizaban, las necesidades y los desafíos de sus ciclos vitales específicos, y las ideas presentes en la sociedad, que subyacían a las interacciones humanas con la naturaleza en relación con el fin de asegurar la alimentación y la salud. Se argumenta que tanto las mujeres como los niños participaron activamente en todos los procesos relacionados con la alimentación y la nutrición y que su trabajo fue clave para asegurar la provisión de alimentos de su grupo. Partiendo de un marco teórico inspirado en una definición tridimensional de la nutrición, esta tesis ofrece una visión integral de los elementos biológicos, sociales y ambientales que influyeron en la alimentación y la nutrición en la Antigüedad. El análisis de las fuentes escritas y bioarqueológicas antiguas contribuye a poner de relieve las múltiples formas en que mujeres y niños participaron en los procesos relacionados con su propia alimentación y nutrición. El marco teórico propuesto se articula con el análisis de las fuentes antiguas con el objetivo de ofrecer un nuevo enfoque sobre el tema.

Aerothermodynamic Analysis of Inlet Air Temperature Effects on Aero-Gas Engine Performance and Optimization for High-Speed, High-Altitude Flight Conditions
Authors: Sabzehali Mohamadreza , Alibeigi Mahdi
Published: August 2023

In this study, the effects of variations in inlet air temperature, Mach number, and flight altitude on the performance of the Ramjet XRJ47-W-5 turbofan engines, the F135PW100 and EJ200 turbofan engines, and the J85 GE17 turbojet engine have been investigated. Thrust, specific fuel consumption (TSFC), fuel flow rate, thermal and propulsive efficiencies, nitrous oxide emissions (EI NOx), and actual inlet air mass flow rate to the engines have been considered as performance parameters. At a flight altitude of 10000 meters and a Mach number of 0.8, with a 20-degree reduction in inlet air temperature compared to the ISA Standard Atmosphere (International Standard Atmosphere), the F135PW100 and EJ200 turbofan engines, as well as the J85 GE17 turbojet engine, experienced thrust increases of 7.5%, 5.33%, and 11% respectively, and TSFC reductions of 1.21%, 0.96%, and 0.23% respectively. For the Ramjet XRJ47-W-5, at a flight altitude of 10000 meters and a Mach number of 3, with a 20-degree reduction in inlet air temperature compared to ISA, thrust increased by 9.11% and TSFC decreased by 1.62%. With an increase in the Mach number, the impact of inlet air temperature variations on engine performance parameters becomes more pronounced. Using a genetic algorithm, the optimization of the studied engines has been conducted within the flight altitude range of 20000 to 40000 meters and Mach number range of 2 to 4.5, based on maximizing TSF, minimizing TSFC, and maximizing thermal efficiency. Among the optimal cases, considering energy consumption and power approach, the TOPSIS decision-making method has been employed to select the best configuration.

CMOS Analog-to-Digital Converter for Perovskite PV Sensing Applications
Authors: Mokogwu Francis , Marzuki Arjuna , Ng Annie , Ukaegbu Ikechi
Published: August 2023

 An 8-bit asynchronous single-ended Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) for the realization of a perovskite photovoltaic (PV) sensing application is presented. Various techniques have been proposed to enhance speed and power efficiency. A bootstrap transmission gate-based sample and hold circuit is proposed to improve sampling linearity and reduce power consumption. The sample and hold circuit is configured to operate at a 90% duty cycle, hence, giving it enough time for the conversion. A two-stage latch dynamic comparator is implemented to ensure high-speed and low power consumption. The SAR ADC also implements an asynchronous SAR logic block, controlled by an internal clock, which eliminates the need for an external clock. The proposed SAR ADC was designed in a UMC 180nm CMOS technology. The SAR ADC is tested with a sinusoidal analog input of 500 mV at 10 kHz frequency and a 4 MHz input clock frequency. The SAR ADC consumes a power of 2.67 mW at a supply of 1.5 V. The proposed ADC is an important unit for application in the fast growing perovskite-based PV industry. 
Unsupervised Domain Adaptation with Debiased Contrastive Learning and Support-Set Guided Pseudo Labeling for Remote Sensing Images
Authors: Biswas Debojyoti , Tesic Jelena
Published: August 2023

Here, we address the challenge of generalizing object detection and labeling in remote sensing data from one dataset to another. It is the variability in different altitudes, geographical variances, weather conditions, and object size across datasets that state-of-the-art DNN largely fails to generalize. Contrastive-based unsupervised domain adaptation attempts to bridge the gap by producing discriminating features for frames and instances across different datasets, and we have shown some progress on the domain alignment on local, global, and instance-aware features for remote sensing data. In this research, we propose using support-guided pseudo-labeling on the target domain instances to enable instance domain adaptation on the source and target datasets. Next, we introduce the contrastive loss function with multiple positive examples to make the model more generalized of the variable appearance of a particular class over images and domains. Also, we proposed debiased contrastive learning based on class probabilities to address the challenge of false negatives in the unsupervised framework. We show the advantages of the proposed model on satellite (DIOR and DOTA2.0) and drone (Visdrone and UAVDT) image datasets.

Grid-forming control plays an essential role in the modernization of HV electrical transmission grids, particularly in mitigating challenges imposed by large voltage disturbances. In this context, the concept of virtual power has gained prominence as a potential approach that improves stability following such disturbances. This paper illustrates the use of virtual power method in enhancing the large disturbance stability given by the grid-forming control. An adaptive virtual impedance is also proposed to further improve system dynamics. The methods are evaluated through large disturbance stability analysis and time-domain simulations. 
Multi-modal Contrastive Learning for Crop Classification Using Sentinel2 and Planetscope
Authors: Patnala Ankit
Published: August 2023

Remote sensing has enabled large-scale crop classification to understand agricultural ecosystems and estimate production yields. Since a few years, machine learning is increasingly used for automated crop classification. However, in most approaches the novel algorithms are applied to custom datasets containing information of few crop fields covering a small region and this often leads to models that lack generalization capability.  In this work, we propose a multi-modal contrastive self-supervised learning approach to obtain a pre-trained model for crop-classification without the use of labeled data. Such multi-modal self-supervised learning exploits the synergies of different data sources to obtain a richer representation of the data. We build our analysis by adapting the DENETHOR dataset developed for a part of Eastern Germany to our usecase.  We use the publicly available Sentinel2 and commercial Planetscope data. While Sentinel2 has higher spectral resolution, Planetscope has finer spatial resolution. For an end-user application, only one source is required. In this work, we analyze and compare the performance of our multi-modal self-supervised model against the uni-modal contrastive self-supervised model using the SCARF algorithm. In addition, we also compare our multi-modal self-supervised model with a supervised model. We find that our multi-modal pre-trained model surpasses the uni-modal and supervised models in almost all test cases.
Generalized Inverse Binary Matrix Construction for Public Key Cryptography Applications
Authors: Haidary Makoui Farshid , Gulliver Aaron
Published: August 2023

The applications of generalized inverse systematic non-square binary matrices span many domains including mathematics, error-correction coding, machine learning, data storage, navigation signals, and cryptography. In particular, they are employed in the McEliece and Niederreiter public key cryptosystems. For a systematic non-square matrix H of size (n-k) x n, n > k, there exist 2k x (n-k) distinct inverse matrices. This paper presents an algorithm to generate these matrices as well as a method to construct a random inverse for systematic and non-systematic binary matrices. The proposed approach is shown to have lower computational complexity than the well-known Gauss-Jordan techniques. The application to public key cryptography (PKC) is also discussed.

Published: August 2023

Introduction: perinatal mortality is characterized by fetal deaths that occur after the 22nd week of management and neonatal deaths that precede six full days of life. This indicator has been a matter of concern and discussion on the part of entities and organizations involved in comprehensive health care for women and children.
Objective: to characterize perinatal deaths in the Metropolitan Region of Greater Vitória (RMGV) in Espírito Santo and identify associated maternal factors in the period between 2008 and 2017.
Methods: ecological and descriptive study with a quantitative approach, carried out in 2019 on perinatal mortality from 2008 to 2017 at RMGV. Data collection was performed by extracting data from the SIM, SINASC, IBGE databases of the Espírito Santo State Health Department, about perinatal deaths and associated maternal factors. The research respects the ethical precepts of resolution 466/12 of the National Health Council.
Results: the distribution of deaths did not occur homogeneously in the municipalities in the RMGV. The municipality of Vitória had the lowest perinatal mortality rates during the study period, on the other hand, in the comparative analysis between the different municipalities that make up the RMGV, the municipality of Fundão presents the worst scenario regarding perinatal mortality over the years. Regarding the underlying causes of death, it is noted that in this study, the three causes with the highest number of occurrences are complications of the placenta, umbilical cord and maternal affections, not necessarily related to the current pregnancy and intrauterine hypoxia.
Conclusion: there were no significant changes in mortality rates in the Metropolitan Region of Greater Vitória. However, the main deaths occurred in neighborhoods with greater socioeconomic inequalities. Maternal causes were highly representative of deaths, raising issues associated with the improvement of public health policies.

This study was conducted to describe the single nucleotide polymorphism (SNPs) within the exon 2 of HLA-DQA1, a gene that encodes a MHC class II antigenthat localized in the surface of many immune cells and they play a central role in the immune system by presenting peptides derived from extracellular proteins, as well asto analyze the consequences of non-synonymous SNPs in this gene using several in silicobioinformatics tools in the patients with Hyper thyrotoxicosis Blood samples were collected, DNA was extracted, and one pair of specific PCR primers was designed to amplify exon 2 of thisgene. PCR experiments were optimized and performed,and PCR products were purified and sequenced from both termini. Sequencing results were analyzed, and each observed nsSNP was further analyzed by several computational tools. Out of six observed SNPs, five of them were non-synonymous. It was found that the deleterious effect of these non-synonymous SNPs wasvaried, and the most damaging mutation was V68F followed by K92N. While the T49S and I99M have a mild parallel effect.However, no clear association was revealed between the observed SNPs of HLA-DQA1 gene and the progression of the Hyper thyrotoxicosis disease. Therefore, the associative pattern of this genetic variation with Hyper thyrotoxicosis disease should be interpreted with caution.

Published: August 2023

Ten copolymer gels were prepared from dimethylaminomethacrylate and 2-acrylamido-methylpropane-1-sulfonic acid with crosslinking agent methylene-bisacrylamide by redox polymerization. Hydrogels were characterized by studying their swelling ratios, the surface morphology by SEM, and studying the porosity and specific surface area by BET technique. The hydrogel copolymers were used to remove Congo red dye from aqueous solutions. It was found that there are two copolymers (C20 and E20) gave the best results for removing this dye from aqueous solutions at pH 7. The adsorption behavior was in agreement with Freundlich's model for C20, while E20 matched with Langmuir's model. It was also found that adsorption of Congo red dye on the two copolymeric hydrogels followed a pseudo-second-order kinetics. The results of the activation energy showed that the adsorption of the dye with the hydrogel C20 is chemisorption in nature, while it is physisorption with the hydrogel E20. Finally, desorption studies carried out in 0.1 M of NaOH and hydrochloric acid, distilled water, and 95% ethanol indicated that the best eluent for dye recovery was NaOH.

Myrtle Witbooi, a pioneering leader of the domestic worker movement, died on January 16 in Cape Town at age 75. Under South Africa’s apartheid rule, she began to organise women in the garage of her employer and went on to become president of the first global union led by women. For 52 years she advocated for the rights of domestic workers, upholding her presidency in both South Africa’s national union of domestic workers and the International Domestic Workers Federation, throughout her struggle with a rare form of bone cancer. Ms. Witbooi’s experience as a domestic worker under apartheid guided her life on the front lines of both a national and global movement to recognise and protect women once considered ‘servants’ without rights. She fought for domestic workers’ first legal protections in South Africa’s democracy, which set basic conditions of employment and allowed over 100,000 women to receive maternity and unemployment insurance over the past twenty years.

The development and implementation of an innovation-oriented strategy are essential for solving the problem of ensuring a consistently high competitive position of food industry enterprises. Taking this into account, they are faced with the need to choose the right strategy for increasing competitiveness, which should be based on using innovative and investment approaches to determine the development vector. The article aims to substantiate approaches to the choice of an innovation-oriented strategy for increasing the competitiveness of food industry enterprises. The research results obtained in the report are based on economic and systemic methods, methods of strategic analysis, and systematic and logical approaches. The article discusses approaches to developing and implementing an innovation-oriented strategy for increasing the competitiveness of food industry enterprises. The model of such a strategy, in general, should provide for the use of a systematic approach and hierarchical subordination of strategic goals, priorities, and objectives of the strategic plan. It has been substantiated that combining competitive and innovative aspects of development into a single concept provides for modifying basic strategies for a food company. The presence of a wide range of alternatives has been revealed, necessitating the development of systems that allow considering the formation of the strategy of food industry enterprises from two positions: the competitive position of the enterprise in the market and the level of development of its innovative potential. Based on the modification of the McKinsey / General Electric model, various combinations of the competitive position of food industry enterprises and their creative capabilities were obtained. The matrix method made it possible to identify alternative options for an innovation-oriented strategy for increasing competitiveness, depending on the positioning of individual subsectors for a different combination of these characteristics. The positions of individual subsectors of the food industry have been established to develop recommendations for choosing the optimal strategy option.

Using nematode traits to evaluate the effects of topography and grazing on the function of wet grassland soils
Authors:   , Elkins Kristina D.
Published: August 2023

Understanding belowground impacts of livestock in rangelands is critical to developing sustainable grazing practices. This is particularly the case in wet grasslands, which face increased pressures in the timing and intensity of grazing in a changing climate. To understand the coupled effects of topography and grazing on wet grassland soils, I examined the generic diversity, feeding composition, and traits of soil nematode communities. I collected nematodes from grazed and ungrazed upland prairies and wet meadows in southern and central Manitoba. Nematodes were extracted from fresh soil cores, counted, identified to the genus level, and assigned to feeding groups. I measured morphological, metabolic, and reproductive traits for a subset of dominant nematode genera and calculated community-weighted means and variances of five nematode traits (length, greatest body diameter, mass, b-ratio, average number of gonads). Topography and grazing did not affect the alpha and beta diversity of nematode genera. However, wet meadows and grazed treatments were characterized by a higher proportion of bacteria-feeding nematodes. On average, larger nematodes with lower b-ratios (i.e., longer esophagus relative to body length) dominated wet meadow soils compared to upland prairie soils. Grazing significantly interacted with topography to result in community-weighted means and variances of nematode traits that were similar across topography. The observed changes in nematode feeding composition and traits suggest that topography and grazing may alter rates of carbon and nutrient cycling in wet grassland soils. This study reinforces the ability of nematode communities, particularly their traits, to serve as valuable bioindicators of soil function in changing environments.

Nyimbo za muziki wa dansi wa Tanzania zilianza nchini Tanzania kipindi cha ukoloni. Nyimbo hizi zinasawiri ujumi mweusi kwa kiasi kikubwa, na zina unusura. Ujumi wa kijamii huwa na dhima muhimu katika kazi za kifasihi za jamii husika. Kila jamii ina ujumi wake. Ujumi wa Waafrika huitwa ujumi mweusi. Huu ni ujumi utokanao na utamaduni wa jamii ya Kiafrika pamoja na mazingira yake. Ujumi huu huweza kutumika kuhakikia kazi za kifasihi za Kiafrika. Makala hii imetumia data za maktabani. Jumla ya nyimbo 8 za kuanzia mwaka 1970-2000 zimetumika. Nyimbo hizo zimeteuliwa kimakusudi, kwa kutumia usampulishaji usonasibu. Uteuzi huo umefanywa kwa zingatia dhima kuu, na ya kipekee, inayojitokeza zaidi kwenye wimbo husika. Mbinu zilizotumika kukusanyia data ni; utazamaji makini, udurusu wa matini na mbinu ya kutalii na kukusanya. Data zimechambuliwa kwa kutumia mkabala wa kitaamuli, na nadharia ya Uhalisia imetumika katika uchambuzi wa data ya utafiti huu. Matokeo ya utafiti wa makala hii yanabainisha kwamba ujumi mweusi una mchango mkubwa katika unusura wa nyimbo teule. Unusura huo umebainika kusababishwa na usawiri, kwa mawanda mapana vipengele mbalimbali vya ujumi mweusi kwenye nyimbo teule. Vipengele hivyo ni; umoja na ushirika, adabu na utii, utu, na matumizi bora ya lugha ya Kiswahili. Hivyo, walengwa wake huvutika kuzisikiliza kwani hugusa mambo yanayojenga ustawi wa jamii yao, hivyo kuwa na unusura. Hivyo, wasanii wanashauriwa kuendelea kutunga nyimbo za muziki wa dansi wa Tanzania zenye usawiri wa ujumi mweusi kwa mawanda mapana. Hali hii itasaidia kuendeleza unusura wa nyimbo hizi, kwa ajii ya usatawi wa jamii ya Watanzania na jamii nyinginezo

W pracy przedstawiono empiryczne porównanie ośmiu metod oceny efektów obiektowych z doświadczeń prowadzonych na wczesnych etapach hodowli. Materiał do badań stanowiły wyniki doświadczeń z pszenicą jarą, pszenicą ozimą i jęczmieniem jarym przeprowadzonych w Choryni, Kobierzycach, Polanowicach, Modzurowie oraz Nagradowicach. Powyższe linie oceniano w doświadczeniach jednopowtórzeniowych z wzorcami (stosowano od 1 do 5 odmian wzorcowych, w zależności od doświadczenia). Wyniki otrzymane dla poszczególnych metod porównywano w oparciu o różne kryteria. Jednym z nich jest kryterium równomierności rozkładu na polu doświadczalnym linii wybranych do dalszych badań (wybierano od 20% do 30% ogólnej liczby badanych linii). Drugie kryterium polegało na porównaniu sum kwadratów różnic między estymatorami efektów badanych linii otrzymanymi przy zastosowaniu różnych metod i estymatorami efektów tych samych linii otrzymanymi przy pomocy klasycznej analizy wariancji doświadczenia wielopowtórzeniowego. Wskazanie najlepszej metody estymacji efektów obiektowych jest trudne, ponieważ wybór metody najlepszej zależał od lokalnych warunków środowiska doświadczalnego w poszczególnych miejscowościach. Na uwagę zasługuje jednakże fakt, iż we wszystkich analizowanych doświad¬czeniach najgorszą okazała się tzw. metoda „nieprzekształconych wyników pomiarów”, czyli ta, w której nie poprawia się otrzymanych pomiarów, a do dalszych badań przyjmuje się ustaloną frakcję (20%–30%) najlepszych linii. Stosunkowo najskuteczniejszymi (w sensie zastosowanych kryteriów) okazały się metody eliminujące przestrzenne zależności między jednostkami doświad¬czalnymi (poletkami).
