‘For me, it was a liberation, like being free again.’ A qualitative approach to the care trajectories of divorced mothers in Spain
Authors: González Granados Paula , Valero Errazu Diana , Sierra Berdejo María José
Published: November 2022

This article deals with the causes and consequences of divorce in a group of women with minor children in Spain, a country in Southern Europe that presents a pre-eminently familistic character based on a marked division of gender roles. We detected an imbalance between qualitative and quantitative studies on this topic, of which the latter are more numerous in the recently published literature. For this reason, here we wish to show the people behind the data by conferring two questions making up the analysis axes of this research. First, we deal with the causes of couple breakups, which are related to inequality in the distribution of housework and care tasks in all cases. Second, we analyse their speeches about work and family conciliation after divorce, with particular importance given to the presence, or not, of a strong family network.
Names in adoption law and policy: representations of family, rights and identities
Authors: Pilcher Jane , Coffey Amanda
Published: November 2022

Names have heightened importance in adoption, affecting the identities of individuals who are adopted and adoptive family making. In this article, we use critical discourse analysis to gauge how names, and especially children’s forenames, are addressed in the specificities of legal and policy texts governing and guiding the milieu of people affected by adoption in England. We argue that the inclusions, omissions and opacity of content on names we uncover are outcomes of underlying representations of ‘family’ within the texts, whereby ‘family surnaming’ is constructed as the pre-eminent naming issue in adoption, above children’s forename-based identity rights. Our focus on names in adoption advances sociological understandings of the power of names in representing family relationships and individual identities, and of how official discourses of law and policy can privilege some types of relationships over others, and the rights of some family members over others.
Monitoring the monitors: a demystifying gaze at algorithmic prophecies in policing
Authors: Gatti Carlo
Published: November 2022

Predictive policing lies at the intersection of a diachronic paradox between the innovativeness of algorithmic prediction and its selective application to archetypes of conventional criminology. Centring on the Italian context, I outline a critique of predictive policing, proceeding from its embeddedness in the neoliberal restructuring of security provision and the increasingly blurred boundaries between private and public agencies. Rejecting the narrative of technical neutrality and operational smartness, I retrace the interdependence of a selective understanding of security that has paved the way for predictive policing and the impact of automated predictions on the governance of crime control. I argue that the production of social harm under predictive policing follows three main patterns: firstly, the continuation of a tolerable rate of street crime; secondly, a dramatic acceleration in the marginalising and stigmatising potential of criminal targeting; and thirdly, the impairment of democratic accountability through tautological schemes of self-legitimation.
Problems in protections for working data subjects: the social relations of data production
Authors: Moore Phoebe V.
Published: November 2022

‘Problems in protections for working data subjects: the social relations of data production’ argues that existing AI and data and privacy regulation do not sufficiently provide protections from harm in the context of data extraction and mining. This is because the approaches taken are individualist in relational positioning and do not take into account differences across data subject types. The argument updates legal philosophical arguments rooted in propertarian and identitarian assumptions for how data harms can be prevented, arguing that what is needed is a discussion of the social relations of data production and the portrayal of a constellation of power relations rather than identifying a data subject as suspended in midair.
Aplicação de uma ferramenta de Business Intelligence para o diagnóstico do uso de água subterrâneas no estado do Paraná e em seus municípios
Authors: Bolonhez Bruna Forestieri , Namba Jhonathan Yoshiaki
Published: November 2022

No Brasil, e no Paraná, o direito de utilização dos recursos hídricos é concedido por meio de outorgas de direito de uso. Considerando a crescente demanda pelo uso das águas subterrâneas, esse trabalho adotou como material de pesquisa os documentos de outorgas concedidas para captações em poços no estado do Paraná. Com o emprego dos bancos de dados do Instituto Água e Terra do Paraná, e realizando a modelagem de dados com a ferramenta de Business Intelligence, gerou-se um relatório interativo detalhado sobre a situação das outorgas vigentes de poços no Estado do Paraná e seus municípios até fevereiro de 2022. Com o sistema criado, tornou-se possível a rápida análise da situação de cada município e do estado como um todo, facilitando a tomada de decisão e adoção de novas medidas públicas para a melhor gestão do recurso. Demostrando a sua aplicabilidade, avaliou-se a situação geral do estado. Neste, os poços outorgados no estado captavam um total de 617,90 milhões de m³ano-1, sendo o Saneamento a principal finalidade dessas captações. Houve, em 2018, um crescimento no volume total outorgado no estado, tendo seu ápice em 2019. Em relação ao número de outorgas emitidas, o uso para fins agropecuários é o principal solicitante desde 2004. Comparando-se todos os municípios do estado, o município de Cascavel teve a maior demanda de água subterrânea (24,97 Mi m³ano-1), com os novos poços apresentando uma tendência de níveis estáticos cada vez mais profundos. Assim, a aplicação dos sistemas de Business Intelligence demonstrou a sua versatilidade para análises de dados qualitativos, quantitativos e espaciais, tornando-se um recurso de grande valia para a gestão das águas.
Ermittlung des Wohnbauflächenbedarfes unter Berücksichtigung kleinräumiger Wanderungsbewegungen. Ein Praxisansatz am Beispiel der Region Halle-Leipzig
Authors: Sell Thorben , Dunkl Anna , Henn Sebastian , Bergfeld Annedore
Published: November 2022

Small-scale, often polarizing changes in the population structure characterized by migration, have a crucial influence on the current development of settlements in Germany. Although state and regional planning tries to manage related demands for residential areas, competition for potential migration gains on the municipal level often leads to an unregulated development of residential areas within the region. This paper therefore seeks to develop an approach for an inter-municipally coordinated planning of residential areas, which takes into account demographic developments, in order to reduce the overall land consumption. In a first step, the residential land requirements that can be derived from expected small-scale population movements are presented in the form of different scenarios for specific municipalities. In a second step, a screening approach is used to identify those municipalities that appear to be suitable for accommodating additional residential development land requirements on the basis of their amenities and accessibility. In a third step, the identified residential land requirements are assigned to test areas with the help of various indicators. The approach is illustrated using the example of the Halle-Leipzig region.

The emission of nitrogen oxide (NOx), nitrogen monoxide (NO) and carbon monoxide (CO) from vehicle exhaust gas generates an adverse effect to the environment as well as the human health. Therefore, the need to reduce such emission is urgent. The decrease of the emission can be achieved through the use of catalytic converter. This study explains the application of catalytic converter prepared from activated carbon to enhance the activity through its adsorption ability. The activated carbon was derived from banana peels after heating them up at 400 ºC for 1.5 hours and activation using natrium hydroxide (NaOH). Several techniques including N2 adsorption-desorption, X-Ray Diffraction (XRD), Scanning Electron Microscopy-Electron Dispersive X-ray (SEM-EDX), and Fourier Transform Infrared (FTIR) were adopted to characterize the activated carbon properties. The activated carbon formed was then coated with copper. The activity of the catalytic converter using activated carbon coated with copper was then tested for its performance on diesel engine Yanmar TF 70 LY-DI with variations in the number of catalyst layers, namely 1 layer (C1), 2 layers (C2) and 3 layers (C3). Sample with three layers (C3) of catalyst exhibited the highest activity with the percentage efficiency in reducing emissions concentration of 48.76 %; 31.27 % and 29.35 % for NOx, NO and CO, respectively.
Sketching Spirit in Everything: Exploring Spirituality, Interconnectivity, and Creativity in Gloria Anzaldúa’s Archived Drawings
Authors: Ishii Sara
Published: November 2022

Gloria Anzaldúa drew important connections between spirituality, interconnectivity, and creativity when she stated, “the idea that everything is spiritual, that I’m a speck of this soul, this creative consciousness, this creative life force; and so is a dog, a rock, a bird, this bedspread, and this wall…Everything is relative, I’m related to everything” (Interviews 2000).  In asserting a universal relation between all beings based on spiritual affinity, Anzaldúa places spirituality at the core of social justice work.  Furthermore, she expands the scope and applications of spirituality to includes all forms of beings and unsettles the separation and hierarchy between humans and nonhumans. In the introduction, I establish Anzaldúa’s articulation of spirituality as social justice oriented, inclusive of all forms of being, and connected to creativity.  Next, I examine three of Anzaldúa’s archived sketches of animals and nature and place these images into conversation with her written theories. While the archive holds numerous sketches that incorporate an animal or nature, I select drawings that contain nature and at least one animal rendered in a complex patterning style.  In my analysis I explore the questions: How can we read Anzaldúa’s sketches through her writings on spirituality? And conversely, what can we learn about Anzaldúa’s theory of spirituality from her archived sketches? Through compositional analysis, I unpack Anzaldúa uses of imagination to articulate a spirituality that indicates interconnections between humans and our environment.  In conclusion, I reflect on the contributions Anzaldúa’s artwork makes in developing her theory of spirituality that creates personal and social change. I argue that academic disciplines invested in analyzing social issues can benefit from examining both Anzaldúa's written and visual theories because she presents a spirituality that is deeply enmeshed with, not removed from, the concerns of marginalized groups.
¿Qué hacen las mujeres en internet?: un análisis del uso de internet en los y las adolescentes en Galicia
Authors: Rodríguez Rivera Paula
Published: November 2022

La expansión de Internet en pleno siglo XXI, se ha convertido en un elemento que se utiliza de forma rutinaria siendo muchas veces asociado a algún tipo de problema relacionado con la frecuencia y forma de uso. En este sentido, los adolescentes son los usuarios de Internet más vulnerables, siendo las mujeres y niñas quienes más sufren los peligros de la red, como el grooming o el sexting, ya que son una población con menos mecanismos de control. En este sentido, el machismo institucional presente en la sociedad occidental se traslada también al mundo en red, dejando a las mujeres en un segundo plano. Es por eso por lo que el objetivo del presente trabajo es analizar las diferencias por sexo de los hábitos de uso, las prácticas de riesgo y el uso problemático de internet de estudiantes de educación secundaria obligatoria (ESO) de Galicia. Para eso, se aplicó un cuestionario a una muestra de 234 estudiantes (entre 12 y 18 años) de toda la comunidad autónoma. Los resultados ponen de manifiesto que las prácticas de riesgo, los juegos de azar online y la pornografía son prácticas más habituales para ellos y ellas se sienten más presionadas para enviar contenido propio sexual. Por último, en el uso problemático de internet se constatan diferencias por género, siendo ellas con un 15.6% quienes presentan más uso problemático. Estos datos revelan la necesidad adoptar iniciativas públicas de carácter formativo que realicen intervenciones dirigidas a dar respuesta a esta problemática desde el campo de la educación, haciendo hincapié en la perspectiva de género, ya que las mujeres y niñas son el segmento poblacional más vulnerable pudiendo así eliminar hábitos o conductas negativas hacia ellas.
La contribución de Manuel Sacristán a los enfoques críticos en la teoría internacional: conocimiento, ética y práctica contrahegemónica
Authors: Morales Hernández Javier
Published: November 2022

Este trabajo presenta algunas de las líneas principales del pensamiento de Manuel Sacristán Luzón (1925-1985), el filósofo marxista español más destacado del siglo XX, con el objetivo de visibilizar la utilidad de su aportación teórica y política para los enfoques críticos de las Relaciones Internacionales. El materialismo inspirado por Marx y Engels ha quedado relegado en cierta medida a un segundo plano del debate en nuestra disciplina, debido a la consolidación de las teorías reflectivistas como principal alternativa al racionalismo positivista. Sin embargo, Sacristán supo combinar el estudio riguroso de los clásicos con los nuevos conceptos elaborados por Gramsci, de quien fue el principal introductor en España. Asimismo, su formación en epistemología y Filosofía de la Ciencia le lleva a tratar de reconciliar las aspiraciones emancipadoras y éticas de la tradición marxista con el conocimiento obtenido de las ciencias positivas. Su práctica como intelectual y militante comunista durante la Guerra Fría mantuvo una actitud crítica y de denuncia, tanto del imperialismo estadounidense como del despotismo de los dirigentes soviéticos. En la etapa final de su vida, su pensamiento se aproxima a movimientos sociales como el pacifismo, el ecologismo y el feminismo, estableciendo un fructífero diálogo que supera las limitaciones del marxismo más tradicional. Así, el artículo se divide en cuatro apartados. El primero se centra en las reflexiones de este autor sobre epistemología y Filosofía de las ciencias sociales, buscando hacer compatible el valor ético y el potencial emancipador de la tradición marxista con el conocimiento científico empírico; una cuestión que enlaza plenamente con los debates entre positivismo y postpositivismo. El segundo apartado se detiene en la influencia de Gramsci en su pensamiento, que fue muy intensa, pese al encaje más o menos problemático del autor italiano con el materialismo y el positivismo de Sacristán. Los apartados tercero y cuarto pasan del plano teórico al de la praxis, analizando su crítica frente a la URSS y su evolución hacia posiciones pacifistas, aunque sin abandonar nunca el marxismo. Por último, en las conclusiones se ofrece una síntesis de sus contribuciones más relevantes hoy, en un contexto en el que algunos debates de la Guerra Fría han vuelto a cobrar plena actualidad.
Transferencia de la agenda internacional de género al estado de Chile: roles, facilitadores y obstáculos
Authors: Troncoso Zúñiga Camila
Published: November 2022

El siguiente trabajo analiza los procesos de transferencia de la agenda internacional de género al Estado de Chile durante los años 1990 a 2019. Los objetivos de la investigación consisten en identificar agendas relevantes, quienes intervienen, los factores que propician la transferencia y aquellos elementos que constituyen obstáculos. La investigación, desde un aspecto teórico, se basó en los estudios de difusión y transferencia de políticas públicas, utilizando como metodología el rastreo de procesos a través de revisión documental y entrevistas semiestructuradas a personajes claves de organismos internacionales, autoridades políticas del mecanismo para el adelanto de la mujer de Chile, funcionarias públicas e integrantes del movimiento feminista del país. En el artículo se examina en primer lugar, qué agendas internacionales han sido relevantes durante el período, tanto aquellas vinculantes como aquellas que generan compromisos políticos de los Estados, se reconocen principalmente la Declaración y Plataforma de Acción de Beijing, la Convención sobre la Eliminación de Todas las Formas de Discriminación hacia la Mujer, la Convención Interamericana para Prevenir, Sancionar y Erradicar la Violencia contra la Mujer y la Estrategia de Montevideo para la Implementación de la Agenda Regional de Género; se establece una diferencia entre el contenido de ciertas agendas y los hitos de información a los mecanismos de seguimiento, los cuales pueden tener mayor o menor influencia según sea el caso. En segundo lugar, se analizan los factores que contribuyeron a que dicha transferencia pudiera llevarse a cabo, tales como la influencia de funcionarias del mecanismo para el adelanto de la mujer, el conocimiento y compromiso individual que poseían, el aprovechamiento de ventanas de oportunidad y la decisión de la autoridad política. En tercer lugar, se analizan los obstáculos que han dificultado estos procesos, tales como la falta de conocimiento y barreras institucionales principalmente, relacionadas con el diseño institucional y la falta de formalización de procesos de difusión e incorporación de recomendaciones. Finalmente, se exponen ciertas discusiones finales que, más que cerrar el tema de investigación, dejan abierto el camino para seguir profundizando en la transferencia de políticas públicas y la implementación de recomendaciones internacionales.
A paradise went under– the unique hydrology of the atlas basin recorded in the pyramid texts
Authors: Quan Zhang Hong-
Published: November 2022

The Pyramid Texts portray a detailed, specific, and vivid scene of akhification (spiritual rebirth), including the positions, shapes, depths, colors, temperatures, inundation events, vegetation, and salinity of the bodies of water as well as the human activities of religion, irrigation, farming, and ferry around the Akhet. This paper reveals that this scene was an actual environment in the Atlas Basin right before the end of the green Sahara. All the above details exactly describe the characteristics of the two terminal megalakes of the basin, based on the water cycle of the green Sahara. The Akhet located at the outlet of the canal connecting these two lakes was a continuation of Atlantis. Most importantly, the Pyramid Texts tell us that, with advanced hydraulic and agricultural technologies, Atlanteans unknowingly triggered the water cycle collapse in the Atlas Basin and inflicted a breach to the green Sahara.
Loss of native forest changes the biophysical dynamics of the water cycle: a brief review
Authors: da Costa Jamerson Souza , Gonçalves de Melo Maria da Glória , Rocha Liberato Maria Astrid , Silveira Funch Ligia
Published: November 2022

This is a brief review of advances in understanding the forest-water relationship, particularly how the loss of native forests affects biophysical aspects of the water cycle. Initially, we address the participation of forests in the water cycle, especially in intracontinental systems, and how changes in land use and land cover can lead to water insecurity. Next, we present a synthesis of the advanced studies on the influence of evapotranspiration on the availability of water vapour to the atmosphere, and how diverse this process is in tropical ecosystems, which makes the possibility on inferences on an intercontinental and global scale complex. We also compiled information on the influence of the presence of native forests on atmospheric circulation and on the formation of condensation nuclei. Finally, we discuss some implications of forest fragmentation and what some studies point out, as well as considerations about the need to include biological aspects in the design and implementation of scientific models and institutional arrangements at local, regional, and transcontinental scales for understanding and maintenance of a resilient water cycle.

Published: November 2022

In the Mantaro river basin, located in Central Peru, an agricultural activity developed, even supplying the capital of Peru. An intense mining activity took place in the headwaters of this basin, and the La Oroya Metallurgical Complex was built a century ago. Mining activity has left mining environmental liabilities, which directly impact the quality of the water and the soil. In this sense, it is very important to investigate the presence of heavy metals and identify the geochemical associations present in surface waters to assess the real impact on the environment. For this purpose, 30 water samples were analyzed, collected from the Mantaro River and the channels that derive water for irrigation and animal consumption. The samples were analyzed by ICP-MS techniques, inductively coupled plasma-mass spectrometry, and ICP-AES, inductively coupled plasma-optical emission spectrometry. For the evaluation of the main physicochemical parameters, the ECA has been used, as the environmental quality standard of Peru, according to the Ministry of the Environment (2017); while for the chemical quality of surface water, the quality standards of the WHO, World Health Organization, were taken as a reference, according to the WHO guide (2017), being the elements considered: Al, As, Mn, Pb, and Zn. Investigations results show that the waters of some sectors have concentrations of As and Pb, which exceed the standards established by WHO, and there are also some specific cases (Muqui canal) in which Al and Mn exceed the WHO standard. In the case of Zn, its concentrations are much lower than the WHO standard.
Holy springs and wells of the leningrad region
Authors: Golubchikov Yu N , Stepanova EI
Published: November 2022

According to the results of the analysis of search queries an interest in information about holy springs has been revealed. An overview of 45 springs of the Leningrad region, attributed to the saints, is presented. Their map has been compiled (M: 1:200000). With the period of the population's self-isolation regime, Internet search queries for natural holy springs are also increasing. Statistical analysis of posts of thematic communities of the VKontakte social network by the tool "Khitalama" testifies to the social demand for information about holy springs references. These data serve as a promising source of information about behavioral geography. It is proposed to improve the network of specially guarding natural territories by including holy springs in it as objects of health, ecological, educational and pilgrimage tourism. On the example of the Leningrad Region, the foundations for the creation of a unified geoinformation system of holy springs are laid.

Authors: Leka Oscar Akue , Ikezam Weje , Brown Ibama
Published: November 2022

Although Wetlands naturally serve phenomenal roles as natural flood control basins, habitats and breeding grounds for species, ecotourism sites, and biodiversity they have, over time, been depleted to meet man’s increasing demand for land space. This study is a longitudinal survey that looked at the nexus between urban growth and wetland loss in Port Harcourt municipality. Primary and secondary data were used. Primary data were obtained from field observations and ground-trotting. Satellite imageries for four epochs: 1990, 2000, 2010 and 2020 were acquired using Google Earth imageries. Data were analysed using the Geographic Information System (GIS) ArcGis10.4.1 software. The shape file of the study area boundary was generated using ArcGIS 10.4.1 and was used to clip the geo-referenced Google earth images for each year (1990, 2000, 2010, and 2020). The reclassified images were converted to polygons and edited. The area of each classification (land uses) was calculated in square meters using the Spatial Query Module in ArcGIS 10.4.1. Data presentation was done using maps, tables, and charts. Results of analysis revealed that there exists spatio-temporal variation in wetland loss in the study area between the years under review with wetland decreasing form 34633511.38m2 in 1990 to 30945235.9m2 in 2000, and to 23297313.11m2 in 2010 to 18688909.45m2 in year 2020. A very high positive correlation coefficient (Rs) of 0.99 obtained expresses the strong relationship between urban growth and wetland loss in the study area. The study recommends that government and its relevant Ministries, Departments and Agencies (MDAs) should embark on wetland creation, development, and conservation to ensure the continuity in the services, functions, and value of wetland ecosystems in the study area.

Published: November 2022

Throughout history, some plants have been taken as a medicinal alternative, which has been little studied. Their phytochemical compounds have been used for many years by our ancestors, demonstrating that they have components capable of saving lives. Heliotropium indicum is quite common in tropical and subtropical countries, it has been reported as a common field weed, but its main components, the pyrrolizidine alkaloids, have a pharmacological potential for different pathologies or pathological processes. So much so that its main alkaloid, Indicine N-oxide has been evaluated in vivo in cancer patients, although it has also been shown to be a hepatotoxic compound. All parts of the plant have important compounds for pharmacological study and identification, individualizing each component and reviewing its potential is important for further study to better understand the plant. All parts of the plant have compounds important for pharmacological study and identification, individualizing each component and reviewing its potential is important for further study to better understand the plant. This review allows to have a potential vision for its use of the different compounds and their effect on humans for a massive use, in addition to analyze the phytochemical uses of Heliotropium indicum and its uses in traditional medicine and its possible arrival in modern medicine as an alternative to treatments currently used.

Published: November 2022

In this study, we present the technical characteristics and the methods applied for fashioning different types of cages used in the aquaculture of Nile tilapia. This study was based on experiments made in geothermal water and fresh water reservoirs in Tunisia. The structures showed high efficiency in small-scale freshwater fish farming. The results of the growth of tilapia fry, reared in the two areas, showed a wide variation. However, with regards to cages’ effect on its behavior and growth rate, a negligible influence was noted. In fact, after the pre-growth phase of the fry in cages in geothermal waters during 35 days, we obtained a daily growth rate (DGR) of 0.41g/day and a specific growth rate of 7.11%/day. These changes are superior to those found in freshwater cages whose DGR was around 0.18g/day and specific growth rate (5.98%/day). Besides, the grow-out trials carried out in the SidiSaad, Ghezala and Lahma Reservoirs have given encouraging results with respective densities of 75 P/m3, 77 P/m3 and 61 P/m3. The use of 2m3 and 3m3 cages, which are relatively of low cost, showed high efficiency during their handling, such as good shape retention in water and especially low mesh clogging. According to the results of the present study, it is recommend the use of cages with a volume of 50m3 above the water surface in order to prevent fish jumping out of the cage, also the assembly of the cages for pre-growth and the grow-out must be carried out within the same reservoir in order to minimize the production costs.

A review of Saprolegniosis
Authors: Forouhar Vajargah Mohammad , Majidiyan Nava
Published: November 2022

The most common infection in freshwater fish is a fungal infection, and they occur when the fish's immune system is weakened. Saprolegnia are fungi found in freshwater ecosystems around the world, and some species may be found in brackish to estuarine waters. These fungi need water to grow and hexose, which is why they are called water molds. Most transmission is by zoospores, which are produced by vegetative hyphae. Fish infections are usually caused by non-living sources, i.e. the fungus hexes on non-living organic matter and then attacks the fish.

Published: November 2022

The xenobiotic and heavy metals are major source of pollutants cause severe illness to the human body and harm ecosystem. Therefore, a study was designed to investigate role of microbes in removal to these contaminants. Two thermophilic bacterial strains (Brevibacillus borstelensis AK1.) and Anoxybacillus flavithermus AK1) were isolated from the Hot Springs of Saudi Arabia and categorised as S11 and S40 respectively. The strains were tested against eight heavy metals via Minimal inhibitory concentrations (MICs) to determine heavy metal resistance. Study revealed that B. borstelensis AK1 efficiently biodegrade Chromium and Nickle with MICs of 3 mm while A. flavithermus actively involved in removal of Chromium with MIC of 3.5 mm. In distilled water, the maximum removal (90%) of Aluminum was achieved by both bacterial strains. The S40 strain was effectively remove 21.6% manganese and 50.9% cadmium. The strain S11 was capable to remove 6.1% manganese. The highest rate of removal of Lead (97.4%) and aluminum (98.5%) was observed by S11 strains. The whole study was conducted on 24-hour incubation utilizing antibiotics cinoxacin, ciprofloxacin (70 µgmL-1) and ampicillin was (3 µgmL-1) for both strains (S11 and S40) as positive control. The current study provides baseline data regarding role of thermophiles in heavy metals removal from water and in future more studies are required to identify the genetic aspects and related pathways associated with the heavy metals removal.

Authors: Khan Fahad
Published: November 2022

As clinicians, we can relate to difficulties in managing and treating children with dental caries, although there are methods like behaviour management, sedation and general anesthetic in managing children. Besides the additional cost and time associated with these methods, most dentists might not have the know-how or facilities to carry out these techniques. The aim of this is article to highlight minimal and non-invasive methods of managing dental caries. During the Covid 19 pandemic, having treatment options that are none or reduced aerosol-generating along with shorter treatment times is an added benefit.

The hepatic abscess is a rare complication related to multiple causes, mostly of biliary origin. Its etiology can be classified on amoebic or pyogenic origin, being more frequent with the bacterial etiology. The development of a hepatic abscess is related in 4.8% to 15% of patients with acute cholecystitis and 21.9% of patients having a biliary disease. The clinical presentation is usually non-specific; it needs to be complemented with an imaging study to make the timely diagnosis. Its management varies according to its evolution and size; both percutaneous drainage and surgical drainage provide adequate management for medium and large abscess with a favorable prognosis. We presented the case of a patient with hepatic abscess formation after a laparoscopic cholecystectomy for acute Lithia sic cholecystitis.

The study aimed to assess the dynamics of land use changes in the urban environment of Yenagoa City, Nigeria as to understand the changes, consequences and ameliorate the changes. Objectives of the study are to determine land use changes that are evident in the study between 1996 to 2020; identify and assess the causes and dynamics of the land use changes that are evident in the study area; ddetermine the consequences of land use changes in the urban environment of the study area; and provide physical planning measures to monitor, control and manage land use changes in Yenagoa City to promote the sustainable urban environment. The study employed a Mixed Methods Research approach of concurrent triangulation and longitudinal research designs for the collection and analyses of data in the study. The study also employed remote sensing technique, Geographic Information Systems, and time series analysis techniques to collect and analyse data for the study. Stratified and simple random sampling techniques were employed for the collection of data. A total of 9 communities were chosen and sampled and 396 respondents (households) were determined and interviewed as sample size using the Taro Yamane formula. Key informants from government agencies and professionals were interviewed using their responses as themes and concepts for content analysis. The study revealed that there are significant land-use changes such as water bodies, vegetation, and built-up areas between 1996-2020. The study also identified population increases and the demand for land for urban development. The study also identified the dynamics that have caused these changes including an increase in the household size, nearness to the workplace, improve security, cheap rent, increase in migrants, employment opportunities and lack of implementation of the development plan. The consequences identified by the study include constant changes in water bodies, vegetation and built-up areas, the prevalence of flooding, encroachment to marginal lands, slum and squatter development, constant pollution, and modification of the social environment. The study recommends that; to achieve a sustainable urban development including the Yenagoa Master Plan of 2004 should be reviewed and implemented guide, control and manage urban land-use changes, the establishment of an urban land-use framework that will foster synergy of all physical planning agencies and institutions, planning and re-planning of new neighbourhoods and existing communities, continuous urban studies of land-use and environment management and encourage citizen education and participation in environmental management in the city.

A study was conducted to document the avian diversity of the Forest Research Centre (FRC) and Forest College and Research institute (FCRI) Mulugu, Telangana, India from January 2020 to December 2020. Birds were surveyed at two different timings of the day i.e. early morning from 7am to 10 am and at evening from 3pm to 6 pm using line transect and point count method. A total of 77 species belonging to 15 orders and 42 families were recorded in which the maximum abundance of the species was recorded in the order Passeriformes. The analysis of dietary preference showed the dominance of the insectivorous community (52 %) followed by Frugivores (13%). The data on residential status revealed that all the 77 species observed, are resident in India with local migratory nature. The recorded species, Black-headed Ibis (Threskiornis melanocephalus) is listed under the near threatened (NT) category in the IUCN red data list. The work highlighted the importance of green cover around urban ecosystems as a preferred habitat for avian populations. FRC supports good bird diversity and protection and management of areas in and around them will help with conservation of the species.

Soil parental materials and anthropogenic activities are the sources of increasing Cd in soils and enrichment in edible parts of plants and creating hazards to animals and human. Thus, it is an important issue to estimate the levels of Cd in soils; straw and grains of rice and wheat plants grown in the soils contaminate with Cd and evaluates human health risk. In surface soil, total Cd (899±497µg kg-1) and Diethylene Triamine Penta Acetate (DTPA) extractable Cd (16.41±13.83µg kg-1) slightly higher by 1.02±0.20 and 1.31±0.45 folds than the subsurface layers, respectively. The DTPA extractable Cd concentration is significantly increased linearly with increasing total soil Cd (r=0.90). Positive significant correlation was found between soils DTPA extractable Cd and soil organic matter (OM) content (r=0.95), while significant negative correlation for both CaCO3 content (r=-0.92) and pH (r=-0.94). In rice Cd concentrations of straw (374±156µg kg-1) and grains (35±16µg kg-1) are significantly correlated with total soil Cd (r=0.89, r=0.86) and DTPA extractable Cd (r=0.84, r=0.74), respectively. Whereas, rice grains Cd is increased with increasing straw Cd (r=0.98). Wheat Cd concentrations of straw (194±71µg kg-1) and grains (18±13µg kg-1) are significantly correlated with total soil Cd (r=0.90, r=0.96) and DTPA extractable Cd (r = 0.91, r=0.95), respectively. Wheat grains Cd is increased with increasing straw Cd (r=0.95). The Cd Transfer factors (TF) as an average is higher in rice grains (0.04±0.014) than wheat grains (0.021±0.016). However, Cd concentrations in the wheat and rice grains are lower than the both EU and WHO/FAO permissible limits (0.24mg kg-1 and 0.4mg kg-1 dry wt., respectively) and so far no potential human health risk is concluded yet.

This paper presents the results of a survey of undergraduate students of Konya Technical University. The results indicate that 97.20% of the participants use the internet daily. When the purposes of using the Internet were examined, it was determined that 19.39% watched online videos and 17.36% used it for homework. In addition, when asked about the process in that they spend the most time in front of the computer, 22.13% stated that they use it for homework, 15.57% watch online videos, and 11.48% play computer games. 33.80% of the participants stated that their families were worried about the use of the internet, and 44.60% stated that their families talked to their children about the correct use of the computer. When the subjects that families talk about with their children are examined, it is stated that 26.60% of them are about being safe online, 18.35% of them are the time they can use the media, and 16.51% are about complying with ethical rules on the internet. Correlation analysis "How many hours do you spend at the computer?" with “Has your family talked to you about the proper use of the computer?” It shows that there is a very high level (r=903) relationship between the questions. Also "How many hours do you spend at the computer?" and "Has your computer use affected your relationships with your friends?" It was determined that there was a high level (r=892) relationship between the questions. Despite the anxiety of the families, 95.90% of the young people stated that they want their parents to trust them in computer use. In the study, the perspectives of young people on computer and internet use and the determination of parents' views through their children are of great importance in terms of fulfilling the relevant duties and responsibilities of parents, and the idea that it will guide the future practices has formed the starting point of this study.

Published: November 2022

The sustainability of livestock production systems in the districts of Oxapampa, Chontabamba and Huancabamba, Oxapampa Province, Pasco Region, Peru was studied. The methodology used was the MESMIS. For the characterization of the livestock systems, the producers were grouped into three groups: traditional extensive livestock system, semi-extensive livestock system and extensive livestock system. In the first instance, the environmental sustainability, economic sustainability and social sustainability with their respective indicators were partially evaluated, to later evaluate it in a comprehensive way through IGS (general sustainability index) and finally to corroborate the grouping of producers, through the analysis agglomerative hierarchical cluster. Through the MESMIS analysis, the traditional extensive livestock system was the most sustainable in the environmental, economic and social dimension, obtaining the highest IGS. Subsequently, the same producers with their environmental, economic and social indicators were subjected to the agglomerative hierarchical conglomerate analysis, there is a cluster with the same selected producers, in the framework MESMIS, which are part of the traditional extensive system.
