Hermenêutica filosófica: um ensaio crítico sobre a proposta gadameriana
Authors: Marques Victor Hugo de Oliveira
Published: April 2021

O presente ensaio pretende: [a] analisar se a proposta de uma Hermenêutica Filosófica, tal como pensou Gadamer, realmente dá conta do fundamento de toda e qualquer hermenêutica; e [b] avaliar a pertinência ou não do locus da filosofia para a hermenêutica. Para atingir esse objetivo, é cogente: [a] evidenciar que a História do Conceito (Begriffsgeschichte) não é capaz de traduzir um núcleo comum de significação para o termo Hermenêutica; [b] reconstruir os argumentos que tornam possível a expressão gadameriana Hermenêutica Filosófica; [c] levantar questões que apresentem a fraqueza central do argumento desde a propriedade especulativa hegeliana, lembrada pelo próprio Gadamer. Este artigo é, por um lado, pesquisa bibliográfica – já que se baseia em referências já consolidadas –, e, por outro, documental, na medida em que pretende revisitar alguns documentos importantes para o resultado. Essencialmente, a discussão é formalmente feita com Gadamer (2008) em seu tratado “Verdade e Método”, o que não impedirá o uso de clássicos da história da Hermenêutica, como: Aristóteles (2016), Schleiermacher (1999), Dilthey (1900), Heidegger (1997, 1999) e o tratado “Ciência da Lógica”, de Hegel (2016), como contraponto. Os resultados preliminares deste artigo problematizam a ideia de Hermenêutica Filosófica e lançam mão da teoria especulativa hegeliana como uma saída para o problema gadameriano.

Authors: Lévano Loayza Sandro Alexander , Calderón Ubaqui Víctor , Trevejo-Bocanegra Ana Paola
Published: April 2021

El quiste residual es el resultado de un tejido inflamatorio periapical remanente producto de una extracción dental sin un curetaje minucioso. Mayormente afecta a los varones y a la maxila. Su diagnóstico depende de los hallazgos del examen clínico, radiográfico e histopatológico. El presente caso tiene como objetivo reportar el caso de un quiste residual en la región anterior de la maxila de la cavidad oral de un paciente adulto del Centro Dental Docente Cayetano Heredia con antecedente de extracciones dentales en el área de la lesión hace 10 meses. Se realizó una enucleación y se tomó una muestra para el examen anatomopatológico, el cual posteriormente confirmó el diagnóstico de quiste residual.
Les polymères de mannose en production animale. 1. focus sur les structures chimiques rencontrées dans les aliments et les propriétés biologiques

Published: April 2021

Les polysaccharides à base de mannose sont très largement répandus dans le monde vivant. D’un organisme à un autre, la longueur du squelette de mannose, le type de liaison entre les sucres, la composition et la longueur des ramifications sont extrêmement variables et confèrent à ces polymères des propriétés fonctionnelles et biologiques différentes. Au-delà de leur rôle structural ou encore de capteur de molécules d’eau dans les plantes, ils participent en particulier à la glycosylation des protéines et sont clairement impliqués dans les phénomènes d’interaction ligand-récepteur. Certains polymères de mannose viraux ou bactériens hautement conservés sont ainsi, chez les animaux supérieurs, reconnus très rapidement par l’hôte qui se défend en initiant une réponse non spécifique, dite « réaction immunitaire innée ». Plutôt reliées par les liaisons α chez les virus, les bactéries et les levures, les unités de mannose sont reliées par des liaisons β chez les végétaux supérieurs. Les β-mannanes sont présents dans tous les produits d’origine végétale, et à des teneurs particulièrement élevées dans certaines familles (palme, guar, coprah) et certains tourteaux utilisés en alimentation animale. Leurs propriétés anti-nutritionnelles observées chez les porcs et les volailles s’expliqueraient principalement par l’apparition d’inflammation intestinale induisant des baisses de performances, des baisses d’efficacité alimentaire et une augmentation des dépenses énergétiques associées à la mise en œuvre du système immunitaire.
Les polymères de mannose en production animale. 2. Les enzymes de dégradation des mannanes dans l’alimentation des porcs et des volailles
Authors: BONNIN Estelle , LESSIRE Michel , WACRENIER Nathaële , ALLEMAN Fabien
Published: April 2021

Les enzymes capables de dégrader les mannanes appartiennent à plusieurs familles d’hydrolases qui se distinguent par les sites de coupure sur ces polysaccharides. La plus connue est de loin la « β-mannanase », seule autorisée en alimentation animale en Europe et qui est spécifique des liaisons β-(1,4) entre deux mannoses. Si on ne se limite pas aux seules enzymes aujourd’hui homologuées pour l’alimentation animale, les mannosidases, les β-glucosidases, les α-galactosidases, et les mannane acétyl-estérases peuvent participer, seules ou en association, à l’hydrolyse des polymères de mannose. L’ajout d’une β-mannanase dans les aliments des volailles et des porcs permet de réduire en grande partie les effets antinutritionnels, en particulier inflammatoires, des β-mannanes. L’épargne de nutriments qui en résulte peut alors être directement valorisée en formulation en déconcentrant l’énergie du régime. Au-delà de l’économie réalisée sur le coût de l’aliment, des améliorations de la performance (indice de consommation en particulier) et de la santé digestive sont très souvent observées.

Published: April 2021

Background: Extremely rare progressive diseases like Sedaghatian-type Spondylometaphyseal Dysplasia (SSMD) can be neonatally lethal and therefore go undiagnosed or are difficult to treat. Recent sequencing efforts have linked this disease to mutations in GPX4, with consequences in the resulting enzyme, glutathione peroxidase 4. This offers potential diagnostic and therapeutic avenues for those suffering from this disease, though the steps toward these treatments is often convoluted, expensive, and time-consuming. Main body: The CureGPX4 organization was developed to promote awareness of GPX4-related diseases like SSMD, as well as support research that could lead to essential therapeutics for patients. We provide an overview of the 21 published SSMD cases and have compiled additional sequencing data for four previously unpublished individuals to illustrate the genetic component of SSMD, and the role of sequencing data in diagnosis. We outline in detail the steps CureGPX4 has taken to reach milestones of team creation, disease understanding, drug repurposing, and design of future studies. Conclusion: The primary aim of this review is to provide a roadmap for therapy development for rare, ultra-rare, and difficult to diagnose diseases, as well as increase awareness of the genetic component of SSMD. This work will offer a better understanding of GPx4-related diseases, and help guide researchers, clinicians, and patients interested in other rare diseases find a path towards treatments.

Published: April 2021

Quantum computers are invaluable tools to explore the properties of complex quantum systems. We show that dynamical localization of the quantum sawtooth map, a highly sensitive quantum coherent phenomenon, can be simulated on actual, small-scale quantum processors. Our results demonstrate that quantum computing of dynamical localization may become a convenient tool for evaluating advances in quantum hardware performances.
Endangered Languages are not Low-Resourced
Authors: Hämäläinen Mika
Published: April 2021

The term low-resourced has been tossed around in the field of natural language processing to a degree that almost any language that is not English can be called "low-resourced"; sometimes even just for the sake of making a mundane or mediocre paper appear more interesting and insightful. In a field where English is a synonym for language and low-resourced is a synonym for anything not English, calling endangered languages low-resourced is a bit of an overstatement. In this paper, I inspect the relation of the endangered with the low-resourced from my own experiences.
Frail Males on the American Frontier: The Role of Environmental Harshness on Sex Ratios at Birth Across a Period of Rapid Industrialization

Published: April 2021

While sex ratios at birth (SRB) have been shown to vary within and across populations, after over a century of research, explanations have remained elusive. A variety of ecological, demographic, economic, and social variables have been evaluated, yet their association with SRB has been equivocal. Here, in an attempt to shed light on this unresolved topic within the literature, we approach the question of what drives variation in SRB using detailed longitudinal data spanning the frontier-era to the early 20th century in a US population. Using several measures of environmental harshness, we find that fewer boys are born during challenging times. However, these results hold only for the frontier-era and not into a period of rapid industrialization. We argue that the mixed state of the literature may result from the impact and frequency of exogenous stressors being dampened in post-industrial societies.

Published: April 2021

In this work, a highly efficient, molybdenum disulfide (MoS2) based near infrared (NIR) heterojunction photodetector is fabricated on a Si substrate using a cost-effective and simple drop casting method. A non-stoichiometric and inhomogeneous MoS2 layer with a S/Mo ratio of 2.02 is detected using energy dispersive X-ray spectroscopy and field emission scanning electron microscope analysis. Raman shifts are noticed at 382.42 cm-1 and 407.97 cm-1, validating MoS2 thin film growth with a direct bandgap of 2.01 eV. The fabricated n-MoS2/p-Si photodetector is illuminated with a 785 nm laser at different intensities, and demonstrate the ability of the photodetector to work in both regions, the forward biased and reverse biased from above 1.5 V and less than -1.0 V. The highest responsivity, R is calculated to be 0.52 A/W while the detectivity D* is 4.08 x 10^10 Jones for an incident light intensity of 9.57 mW/cm2. The minimum rise and fall times are calculated as 1.77 ms and 1.31 ms for an incident laser power of 9.57 mW/cm^2 and 6.99 mW/cm^2 respectively at a direct current bias voltage of 10 V. The demonstrated results are promising for the low-cost fabrication of a thin MoS2 film for photonics and optoelectronic device applications.

Published: April 2021

Our study examines the association of the presence of mildew, cockroaches, and pets in homes as well as household dust allergens with the prevalence and/or severity of allergic diseases. No study has concurrently assessed home environment exposures in relation to allergic conditions in the general US population. Data from 5,409 participants from the 2005-2006 National Health and Nutrition Examination Survey living in their current homes for ≥1 year were analyzed. Multivariate logistic regression analyses between home exposures and allergic diseases prevalence and severity were performed. In adjusted analyses, mildew was associated with higher current asthma, allergies, and allergic rhinitis prevalence; endotoxin, with higher current asthma prevalence), and dust Canis familiaris (Can f) 1, with higher allergic rhinitis prevalence. However, presence of cockroaches and dust Dermatogoides farinae (Der f) 1 were associated respectively with lower current asthma and allergies prevalence. Presence of mildew, dust Der f1, Dermatogoides pteronyssinus (Der p) 1, Feline domesticus (Fel d) 1, and endotoxin were all associated with asthma and/or wheeze severity. Non-atopic asthma was more frequent with mildew and/or musty smell dust and higher dust Fel d1 concentration, while atopic asthma was more prevalent with higher Can f1and endotoxin concentrations in dust. This study confirms previous relationships and reports novel associations, generating hypotheses for future research.

SARS-CoV-2 infects a range of host species. However, the susceptibility of companion animals to SARS-CoV-2 and their potential ability to transmit the virus to humans remains unclear. Here, we present a detailed clinical description of an immunosuppressed dog that was infected with SARS-CoV-2. The dog had severe gastrointestinal (GI) clinical signs, coagulopathy, elevated hepatic transaminases, and met canine systemic inflammatory response syndrome criteria, without respiratory clinical signs, mirroring a subset of humans with GI-restricted COVID-19. Viral sequencing demonstrated divergence from other reported sequences, based on phylogenetic analysis. The dog shed high levels of virus for a prolonged time period with positive virus isolation. The dog’s immunosuppressed state may have increased both susceptibility to infection and disease progression. Together, our findings suggest that certain individual companion animals may be at higher risk for severe SARS-CoV-2 infection, COVID-19-like disease, and high viral shedding, which may pose a transmission risk to humans.
From Cyberpunk to Cramped Dweller: The Peculiar History of Hong Kong ‘Heterotopias’
Authors: McCoy Daniel
Published: April 2021

75.6% of land comprising Hong Kong remains undeveloped according to the special administrative region’s planning department. In turn, Hong Kong’s constricted real estate, now estimated to be the world’s costliest, has created eye-popping living arrangements historically and contemporarily. Denizens’ colorful reputation and imagination for flouting city ordinances, zoning laws, and spatial management stand emblematic of tenacious self-sufficiency and a free-spirited brand of runaway capitalist initiative. Why is this conspicuous trademark of Hong Kong’s societal fabric very much alive in the 21st Century? Why does this matter in a rapidly urbanizing world witnessing the ascension of mega-urban centers alongside ever-widening socioeconomic chasms? This paper intends to illuminate the peculiar origins and longevity of the Kowloon Walled City, an urban monolith of notoriety and autonomy that blossomed in a semi-legal grey zone unencumbered under British protectorate rule for nearly a century. Parallels will connect the linear trajectory between Kowloon’s hardnosed living to today’s comparable Chungking Mansions and the hundreds of thousands of cage homes appearing in all corners of the city. This paper aims to answer why these residential paradoxes continue to function with efficiency and relevancy, posing solutions for indigent housing while exacerbating the stigma of social and economic ostracism.
Breaking the Cycle: Women’s Perceptions of the Causes of Violence and Crime in Informal Settlements in Nairobi, Kenya and their Strategies for Response and Prevention
Authors: Winter Samantha , Obara Lena Moraa , Aguilar Nathan Jason , Johnson Laura
Published: April 2021

The purpose of this study was to identify potential causes of violence and crime in informal settlements and residents’ strategies for response and prevention to these issues, as perceived by women living in Mathare informal settlement in Nairobi, Kenya. A total of 55 in-depth interviews were conducted with women living in the informal settlement in 2015-2016. A modified grounded theory approach was used to guide data collection and analysis. The most common contributor to violence and crime identified by women in Mathare informal settlement was idle youth, but leadership and government challenges, corruption and/or inadequacy of police, community barriers, tribalism, and lack of protective infrastructure also emerged as contributing factors. Despite facing many economic, environmental, and day-to-day challenges, women in Mathare identified violence and crime as predominant issues; thus, developing effective response and prevention strategies to these issues in informal settlements is paramount. Women suggest there are many strategies and initiatives to reduce and prevent violence and crime in informal settlements, but also identified barriers to implementing them. Findings suggest there is a need for trust-building between formal and informal organizations and institutions, systems of accountability, and long-term investment to foster sustainable and effective violence and crime response and interventions in these settlements.

In June 2020, a door-to-door household survey was conducted in Mvolo County, an onchocerciasis endemic area in South Sudan. A total of 2,357 households containing 15,699 individuals agreed to participate in the study. Of these, 5,046 (32.1%, 95%CI: 31.4-32.9%) had skin itching and 445 (2.8%, 95% CI: 2.6-3.1%) were blind. An epilepsy screening questionnaire identified 813 (5.1%) persons suspected to have epilepsy. Of them, 804 (98.9%) were seen by a medical doctor and in 798 (98.1%) the diagnosis of epilepsy was confirmed. The overall epilepsy prevalence was 50.8/1000 (95% CI: 47.6-54.4/1000) and prevalence of nodding syndrome was 22.4/1000 (95% CI: 20.1-24.9/1000). Younger age, being male, skin itching, blindness and living in a village close to the Naam river were risk factors for epilepsy. The annual incidence of epilepsy was 82.8/100,000 (95% CI: 44.1-141.6/100,000). In conclusion, a high prevalence and incidence of epilepsy was observed in Mvolo, South Sudan. Strengthening the onchocerciasis elimination programme is urgently needed to prevent epilepsy in this region.

Published: April 2021

Forests constitute a key component of the Earth system but the sustainability of the forest reserves in the semi-arid zone is a real concern since its vegetation is very sensitive to the climate fluctuation. The understanding of the mechanisms for the interaction vegetation-climate is poorly studied in the context of African Sahel. In this study, the characteristics of the vegetation response to the fluctuations of precipitation and temperature is determined for the forest reserve of Fina. Rainfall estimates, air temperature and NDVI are used to establish the lag correlations between fluctuations of vegetation and climate variables at both seasonal and interannual bases. Results shows increasing tendency of NDVI started from the 1990s coinciding the recovery of the rainfall from the 1980s drought and the obtained correlation(r=0.66) is statistically significant (pvalue<0.01). The strongest responses of vegetation to rainfall and temperature fluctuations were found after 30 and 15 days, respectively. Moreover, at shorter time lag (e.g. 15 days) more pronounced vegetation responses to both rainfall and temperature were found in agricultural dominated land while at longer time lag (e.g. 30 days) stronger response was observed in Bare dominated land. The vegetation response to the climate fluctuation is modulated by the land use/cover dynamics.
Keywords: NDVI, Rainfall, Air temperature, vegetation response, Fina Forest Reserve, Mali.

Published: April 2021

A challenging problem in the aquaculture industry is bacterial disease outbreaks which results in the global reduction of fish supply and foodborne outbreaks. Biofilms in marine pathogens protect against antimicrobial treatment and host immune defence. Zeolites are minerals of volcanic origin made from crystalline aluminosilicates which are useful in agriculture and in environmental management. In this study, silver ion-exchanged zeolite A of four concentrations; 0.25M (AgZ1), 0.50M (AgZ2), 1.00M (AgZ3)and 1.50M (AgZ4) were investigated for biofilm inhibition and antimicrobial properties against two predominant marine pathogens V. campbelli and V. parahemolyticus by employing the Minimum Inhibitory Concentration(MIC), Crystal Violet Biofilm Quantification assays as well as Scanning Electron Microscopy. In the first instance, all zeolite samples AgZ1-AgZ4 showed antimicrobial activity for both pathogens. For V. campbellii AgZ4 exhibited the highest MIC at 125.00 µg/ml while for V. parahaemolyticus the highest MIC was observed for AgZ3 at 62.50 µg/ml. At sublethal concentration, biofilm inhibition of V. campbelli and V. parahemolyticus by AgZ4 were observed at 60.2% and 77.3% inhibition respectively. Scanning electron microscopy exhibited profound structural alteration of the biofilm matrix by AgZ4. This is the first known study that highlights the potential application of ion-exchanged Zeolite A against marine pathogens and their biofilms.

Authors: Amal Ahmad Ikhlasul , Pandin Moses Glorino Rumambo
Published: April 2021

Background: A person living with HIV / AIDS bargains with stressors such as discrimination, stigma depression, and several psychological impacts. The stressors experienced by people with HIV/ AIDS will certainly have an impact on daily activities, welfare, and management of medications which in general will have an impact on the quality of life. To deal with these stressors, it is necessary to have good and proper coping from within the PLWHA. Coping strategies need to be owned and carried out by PLWHA in order to respond adaptively to the stressor conditions experienced. Purpose: The aim of this review is to describe the stress experienced and the coping strategies used among PLWHA. Methods: This literature review used keywords in the search for international references are coping strategy, stressor, HIV-AIDS. Inclusion criteria: selection of titles that are relevant to the formulation of the problem and objectives, full-text articles in English, articles published from 2019 to 2021. The exclusion criteria used were coping strategy articles that did not involve HIV patients. Search references from electronic database sources namely ProQuest, CINAHL, and ScienceDirect.Six articles that are deemed worthy of analysis are then discussed or analyzed. Results: Age, gender and sexual orientation have contributed to the emerging stressor among PLWHA. The internal and external coping strategies focusing on the problem are important for PLWHA in handling the stressor. Conclusion: People with HIV-AIDS have many stressors in their lives, but they also have proper coping strategies depending on their internal and external conditions.

The prevalence of overweight/obesity in the adult population in the Philippines has doubled in the past 20 years. Zumba exercise has recently been implemented throughout the Philippines. However, there is scarce information on the effects of Zumba on obesity and Zumba participants’ characteristics in the Philippines. This study described the current practice of Zumba in the Philippines, along with the practitioners’ characteristics, and identified factors associated with Zumba participation. In this observational, cross-sectional study, a structured questionnaire was used to survey 10 Zumba locations in September 2019. Anthropometric measurements of participants were assessed. Respondents included 171 women (88.6%) and 22 men (11.4%), with a mean (±SD) age of 44.1 (± 8.9) years. All respondents answered that Zumba was enjoyable, and some answered “very enjoyable.” Determinants of frequent participation were as follows: being older than the mean age of participants, starting Zumba to enjoy dancing, starting Zumba not to lose weight, shopping mall location, and participation fee required. “To enjoy dance” being a motivation for Zumba practice was identified as a determinant of frequent participation, rather than “to lose weight.” The element of “enjoyable” may strongly influence continuation and frequent participation of Zumba exercise in the Philippines.

The organic solar cells (OSCs) have drawn attention in the past decade due to its cynosure in industrial manufacturing because of its promising properties such as low weight, highly flexible and low cost production. However, low η restricts the utilization of OSCs for potential application such as low cost energy harvesting devices. In this paper, OSCs structure based on triple junction tandem scheme is reported with three different absorber materials with the objective to enhance the absorption of photons which in turn improves the η, as well as its correlating performance parameters. The investigated structure gives the higher value of η = 14.33% with Jsc=16.87 (mA/m2), Voc=1.0 (V), and FF=84.97% by utilizing a stack of three different absorber layers with different band energies. The proposed structure is tested under 1.5 (AM) with 1 sun (W/m2). The impact of top, middle and bottom sub cells thickness on η is analyzed with a terse to find the optimum thickness for three sub cells to extract high η. The optimized structure is then tested with different electrode combination and the highest η is recorded with FTO/Ag. Moreover, the influence of upsurge temperature is also demonstrated on the proposed structure and observed that the upsurge temperature has greatly affected the electrical parameters of the device and η decreases from 14.33% to 11.40% when the temperature of the device rises from 300-400 K.

Sphingolipids are lipids derived from an 18-carbons unsaturated amino alcohol, the sphingosine. Ceramide, sphingomyelins, sphingosine-1-phosphates, gangliosides and globosides, are part of this group of lipids that participate in important cellular roles such as structural part of plasmatic and organelle membranes maintaining their function and integrity, cell signaling response, cell growth, cell cycle, cell death, inflammation, cell migration and differentiation, autophagy, angiogenesis, immune system. The metabolism of these lipids involves a broad and complex network of reactions that convert one lipid into others through different specialized enzymes. Impairment of sphingolipids metabolism has been associated with several disorders, from several lysosomal storage diseases, known as sphingolipidoses, to polygenic diseases such as diabetes and Parkinson and Alzheimer diseases. Sphingolipids are mainly located in central nervous system, and their abundance and distribution depend on brain development state and cell type. Although several studies have expanded the knowledge about sphingolipids function both in health and disease, it is still necessary to continue their study to understand the cellular implications of novel sphingolipids. These studies will also contribute to the diagnosis and treatment of diseases in which these molecules are part of their pathophysiology. In this review, we summarize the main sphingolipid characteristics and current knowledge about the synthesis, catabolism, regulatory pathways, participation in action potential and ionic channels, among other relevant functions.

Selection of appropriate friction factors is paramount for accurate prediction of key flow characteristics in gas–liquid two-phase flows. In this work, experimental investigation of vertical air and oil (with viscosities up to 200 mPa s) flow in a 0.060-m ID pipe is reported. Superficial air and oil velocity ranges utilized are from 22.37 to 59.06 m/s and 0.05 to 0.16 m/s respectively. The influence of estimation of interfacial friction factor on accurate determination of film thickness, void fraction and pressure gradient was investigated using a two-fluid model. The results indicated that the two-fluid model is capable of accurately predicting flow characteristics. Further, it reveals that the best performing correlations are the Belt et al. and Ambrosini et al. correlations.

Treatment with calcitriol, the hormonal form of vitamin D, has shown beneficial effects in ex-perimental models of acute lung injury. In this study we aimed to analyze the associations be-tween calcitriol supplementation and the risk of SARS-CoV2 infection or COVID-19 mortality. Individuals ≥18 years old living in Catalonia and supplemented with calcitriol from April 2019 to February 2020 were compared with propensity score matched controls. Outcome variables were SARS-CoV2 infection, severe COVID-19 and COVID-19 mortality. Associations between calcitriol supplementation and outcome variables were analyzed using multivariable Cox proportional regression. A total of 8076 patients were identified as being on calcitriol treatment. Advanced chronic kidney disease and hypoparathyroidism were the most frequent reasons for calcitriol supplementation in our population. Calcitriol use was associated with reduced risk of SARS-CoV2 infection (HR 0.78 [CI 95% 0.64-0.94], p=0.010), reduced risk of severe COVID-19 and reduced COVID-19 mortality (HR 0.57 (CI 95% 0.41-0.80), p=0.001) in patients with advanced chronic kidney disease. In addition, an inverse association between mean daily calcitriol dose and COVID-19 severity or mortality was observed in treated patients, independently of renal function. Our findings point out that patients with advanced chronic kidney disease could benefit from calcitriol supplementation during the COVID-19 pandemic.

The major global pressures of rapid urbanization and urban growth are compounded by climate impacts resulting in increased vulnerability for urban dwellers, with these vulnerabilities exacerbated during COVID-19. Much of this is concentrated in urban and peri-urban areas where urban development spreads into hazard-prone areas. Often this development is dominated by poor quality homes in informal settlements or slums with poor tenure security. Lessons from a current resilience-building project shows that the fit-for-purpose (FFP) approach to land administration can provide a solution to increase the number of households with security of tenure and improve resilience outcomes as informal settlements grow. This paper discusses the influence of FFP land administration on vulnerabilities to multiple shocks related to climate change and COVID-19. This paper proposes ways the growth of human settlements can be better managed through responsible governance of land tenure rights, and effective land-use planning to improve resilience to different shocks and stresses and provide adequate access to safe land and shelter. Land administration systems can support improved resilience to the multiple stressors of climate and pandemics through improving tenure security and enhancing land use planning controls. Climate change adaptation and risk management need to be better mainstreamed into two major elements of land governance: (i) securing and safeguarding of land rights, and (ii) planning and control of land-use.

Species of the Vibrio genus are commonly reported as agents of food poisoning outbreaks associated with fish consumption. The objective of this study was to assess the antimicrobial activity of the essential oils of Origanum vulgare and Ocimum basilicum against Vibrio parahaemolyticus and Vibrio vulnificus, as well as to assess their addition to fillets of Mugil platanus and sensorial acceptance among consumers. The antimicrobial activity was analyzed by the disc diffusion test and minimal bactericidal concentration (MBC). M. platanus fillets, experimentally contaminated, were marinated for 24 hours in a solution containing 1.0% and 1.5% of essential oil of O. vulgare. For the sensory analysis, samples marinated in 1.5% of O. vulgare oil were prepared and offered to 100 testers. The oil of O. basilicum shows no antimicrobial activity, so its application would be ineffective; for such reason the subsequent tests were not performed. However, the essential oil of O. vulgare produced inhibition halo diameters ranging from 24.6 to 34.1 mm, on average, and the MBC ranging from 3.9% to 15.6%. When added to the product, the essential oil of O. vulgare eliminated the microorganisms that were experimentally inoculated. In the sensorial analysis, samples marinated in 1.5% of O. vulgare essential oil obtained an average of 6.82 of acceptance note among consumers.

In Poland, e-learning already has a tradition that goes back over a decade. The Covid-19 pandemic has placed new challenges before all fields of life – including all levels of education. They now encompass almost ten months of experience in teaching at faculties of architecture – including the teaching of engineering modules. The construction and materials science module is key here as it provides the basis for developing construction-phase designs. This module is typically a significant teaching problem and the current situation concerning teaching has exacerbated this. This is a serious challenge for students and teachers alike. Preparation and delivery of online design studio classes requires more time. Instructors should also intensify their self-education efforts. However, there is nothing that can replace interpersonal master–student relationships, contacts, inspiration by peers, practical training and laboratory research.

The 19th century brought key changes in the way cities and their green areas were shaped. One of the key decisions implicating the process of industrialisation, and thus the development of Lublin, was the determination of the location of the Vistula River Railroad Line and the railway station building in Przedmieście Piaski. This process was to be counterbalanced by the newly created public green areas. The aim of the article is a comparative analysis of Lublin's parks in the context of the trends in garden art and realisations of public parks in Europe.

Stunted juveniles of Catla catla (Hamilton, 1822) were produced through 150 days of stunting with five combinations of density and photoperiod. These stunted juveniles were subsequently polycultured in grow-out ponds for eight months along with rohu (Labeo rohita) and mrigal (Cirrhinus mrigala). In grow-out trial, the five treatments with different combinations of stocking density and photoperiod comprised, control (20 m-3, 12L/12D), T-1 (30 m-3, 12L/12D), T-2 (40 m-3, 12L/12D), T-3 (20 m-3, 6L/18D) and T-4 (20 m-3, 0L/24D). After eight months of culture, growth curves of stunted catla in all treatments were non-convergent and inferior to control, indicating no compensatory growth response. Although survival (70-73%), average body weight, (ABW; 667-755 g) and weight gain (648-729 g) in grow-out phase were statistically similar in the groups with different stocking density (Control, T-1 and T-2) (p>0.05), the grow-out survival was relatively higher in T-2 (73.3%), indicating its positive correlation with higher stunting density. In contrast, juveniles stunted with reduced photoperiod (T-3 and T-4) showed significantly lower ABW and weight gain (p<0.05). The poor survival in T-3 and T-4 (40-43%) indicated significant effect of stunting with reduced photoperiod on subsequent grow-out survival and yield performance. Based on the results, the study recommend the use of rearing density up to 40 m-3 for juvenile stunting in catla.

Breeding performance of stunted rohu Labeo rohita (Hamilton, 1822) was compared with normally reared rohu. Randomly selected stunted and normal fishes were tagged and reared together in a single earthen pond for broodstock development. Both groups exhibited growth enhancement during the broodstock development period, though normal fishes were found larger in size than the stunted fishes, after the rearing period. Gonadosomatic Index (GSI) of female fishes indicated a similar trend of ovary growth in both the groups. Breeding performances of the broodstocks were evaluated by induced breeding trials. Parameters such as absolute fecundity, relative fecundity, number of spawns produced and hatching percentage were significantly higher (p<0.05) (almost double) in normal fishes than the stunted fishes. The present results indicate that the stunting process (6 months) is having detrimental effect on the breeding performance of rohu and thus stunted fishes are not ideal for broodstock development.

Knowledge on the socio-economics and livelihood status of fishers is important in view of stagnating capture fisheries production in recent years and to plan suitable additional livelihood interventions. A study undertaken among the coastal fishers (n=145) of Puducherry and Karaikal Districts of Puducherry Union Territory along the south-east coast of India in 2018-19, indicated that while fishing was the full time occupation for Karaikal fishers, about 56% of the coastal inland fishers of Puducherry District realised their income from non-fisheries occupations due to insufficient emolyment and income in fisheries. The fishers’ mean livelihood score was found to be 70% which indicated that they need supplementary activities for employment and income generation. Therefore, Department of Fisheries (DoF) may plan a two-pronged strategy comprising natural resource restoration measures such as re-stocking and stock enhancement involving habitat protection. Similarly the DoF may inititate capacity enhancement programme on culture based fisheries like cage and pen farming in the open waters with the technical support of research institutions and homestead based additional income generating activities with the support of non-governmental organisations to enhance the livelihood security of fishers. It is right time that the DoF may propose plans for both resource conservation and culture fisheries based livelihood security programmes under the newly launched Prime Minister’s Fisheries Development Scheme (Pradhan Mantri Matsya Sampada Yojana-PMMSY) of Govt. of India to ensure the livelihood security of fishers.

The preferences of rural youth towards different fisheries vocations have been assessed using the Thurstone paired comparison technique. Six major fisheries vocations which trainings were imparted to the rural youth by the Krishi Vigyan Kendra, Doda during 2016-17, 2017-18 and 2018-19 were identified. A sample of 94 rural youth was randomly drawn from 940 rural youth who attended various awareness programmes, training programmes and exposure visits organised by KVK Doda independently or in collaboration with National Fisheries Development Board (NFDB), Hyderabad and Directorate of Coldwater Fisheries Research (DCFR), Bhimtal during these three years. Trout culture with the highest scale value of 0.563 was the most preferred fishery vocation by the rural youth and aquarium making was the least preferred with scale value of 0.00. Other vocations viz., carp culture, fish seed production, ornamental fish production and fish feed production were found in between this continuum with varying degrees of the scale distances. The average value of Absolute Discrepancy (AD) estimated was 0.009, which implies that the calculated scale values of the various fisheries vocations had very high level of consistency.
