El metaboloma humano es una vasta colección de moléculas de bajo peso molecular como lípidos, péptidos, ácidos orgánicos, carbohidratos, aminoácidos y nucleótidos que actúan como sustratos o productos del metabolismo y que están relacionadas con funciones celulares esenciales como, nutrición, crecimiento y reproducción, diferenciación, señalización y apoptosis. El análisis integral del metaboloma es el tema central del enfoque de la metabolómica, y desde una orientación aplicada a las ciencias biomédicas y la investigación clínica, constituye una herramienta muy valiosa para conocer de forma global los procesos patológicos y conducir al descubrimiento de biomarcadores de diagnóstico, progresión y pronóstico de evolución. La RMN es una herramienta analítica que destaca por su robustez y reproducibilidad, ya que permite la detección, identificación y cuantificación de múltiples matabolitos de forma simultánea. Esto hace que sea uno de los métodos más empleados en los estudios de metabolómica. Los datos obtenidos con RMN son posteriormente sometidos a análisis estadístico multivariable con la finalidad de extraer la información diferencial entre los grupos de estudio a partir de su metaboloma, y conducir a una descripción biológica de los procesos relacionados con patologías e identificar biomarcadores, evaluar cambios asociados a la nutrición o variaciones ambientales, entre otras posibilidades.

Internet of Things (IoT) devices has completely new challenges regarding security and privacy. Blockchain technology could be a great to mitigate challenges of data security and privacy relay in the IoT. Crypto currency networks like Bit coin, can prove to be required towards understanding concept of decentralized, security and Leveraging of blockchain for privacy preserving. Differential privacy is a mathematical technique of adding a controlled amount of randomized noise to a dataset to prevent anyone from getting information about individuals in the dataset. The added randomized noise is in controlled manner. Therefore, the resultant dataset is still accurate enough to generate aggregate output while maintaining the privacy of individual participants. As Block chain is a peer-to-peer distributed ledger, it is an optimal way for preventing identity, monitoring, non-repudiation and providing tracking in IoT, so due to these aspects we can explore future research challenges to preserve privacy in blockchain.

Efficient use of energy plays an important role in the development of smart grid in power systems. Therefore, proper monitoring and control of energy consumption is a key step. The main priority is with smart grid. The existing energy meter system has many problems. One major problem is the lack of full duplex communication. To solve this problem, we propose a smart energy meter based on Internet of Things (lot). The proposed smart energy meter monitors and calculates power consumption using ESP 8266 12E, a Wi-Fi module and uploads it to the cloud, from where the consumer or manufacturer can view the readings. Hence, the energy analysis of the consumers become much easier and more controlled. This system also helps to detect power theft. So, this smart meter helps with home automation using IoT and enabling wireless connectivity, which is a big step towards the digital transformation of India
Museums of Varanasi Safeguarding Intangible Cultural Heritage
Authors: Ms Jawa Madhur
Published: April 2022

Heritage embraces not only the collection of objects but also includes intangible manifestations of the living expression. At the 32nd session of the General Conference of UNESCO in Paris, from 29th September to 17th October 2003, “The Convention for Safeguarding of the Intangible Cultural Heritage” was adopted. Museums as guardians of tangible heritage were looked upon, to participate in this initiative. ICOM immediately responded to the call and declared “Museum and Intangible Heritage” as the theme of its 20th General Conference that occurred in Seoul in 2004. Museums were re-defined, from the traditional role of collection of objects to the dynamic role of documenting and exhibiting the intangible aspect of the object as well. This paper seeks to explain what intangible heritage is and how digital implication in museum exhibition can be an aid in preserving the intangible aspect of the object by citing the example of two unique museums of Varanasi i.e., Virtual Experiential Museum and Kashi Dham, which is established to showcase the culture of Varanasi. This paper will further discuss the changing role of museums and the importance of digital heritage preservation.

Authors: Belmahdi Amel , Li Jia , Muirhead Bill
Published: April 2022

A growing body of research has revealed that the use of digital technology, including digital media, for writing instruction positively impacts English language learners’(ELLs’) learning and engagement; however, little is known about how this instruction impacts the development of ELLs’ writing skills. This scoping literature review is comprised of empirical evidence from 32 studies published between 2010 and 2020 that reported on the impact of digital technology-supported writing instruction on youth ELL’s writing skills. Although the types of digital technology media that were used varied across the studies, the results revealed that all 32 studies found a positive or perceived positive impact of digital technology-supported writing instruction on ELLs’ writing skills in areas of grammar, language mechanics, metalinguistic awareness, organization, sentence/paragraph structure, and/or word choice/language use. Specifically, 29 articles reported positive outcomes or perceived positive outcomes, while three showed mixed results in which certain areas improved but not others. Pedagogical implications, and recommendations are provided to language educators and youth ELLs.
Cultural Barriers to Exclusive Breastfeeding Among Children Aged 0-6 Months in Tamale Metropolitan Area of Ghana
Authors: Issah Habibu
Published: April 2022

Background: The World Health Organization recommends exclusively breastfeeding (EBF) for 6-months commencing at birth, with early breastfeeding commencing within 30 minutes of delivery. Cultural factors have been discovered to influence women's choice to EBF. The research was to determine the cultural influences on EBF and its implications on the nutritional status of infants 0-6 months. Methods: A descriptive cross-sectional study was conducted. The study included 300 women of reproductive age (18-45 years old) who had infants of 0-6 months and were accessing services at child welfare clinics in Tamale, Ghana. Data was collected using interviewer-administered questionnaire between mid-July to mid-August 2021. Results: Most of the mothers (54%) had poor knowledge of exclusive breastfeeding. More than half (72%) did not practice exclusive breastfeeding. Most mothers (57%) did not offer colostrum to their newborns. Mothers-in-law influenced their daughters-in-laws breastfeeding behaviours. Over 50% of those who did not practice EBF said it was taboo to indulge in sex while EBF, to EBF when pregnant, to EBF when there was insufficient breast milk for infants signified by their frequent crying, and to EBF when mothers are likely to face challenges introducing complementary foods after 6 months. Most of the newborns had indications of underweight (69%), stunting (68%), and wasting (66%). Conclusion: There are greater needs to develop health teaching, health education, and counselling strategies to change knowledge, attitude, and practices. Again, negative attitudes and behaviours of mothers and the community as whole regarding EBF could also be addressed using community-based social marketing approach.

In modern conditions, among the many socio-economic problems of the progress of states, there is a particularly urgent problem of restoring and preserving the environment, as well as natural resources to meet the needs of all mankind and its next generation. Therefore, it is impossible to abandon the problems of environmental accounting at the present time, since the situation is very complex and every year it becomes more difficult to solve the problems that arise. To date, the entire range of information on environmental protection is far behind its demand, which hinders the improvement of the existing mechanism of environmental management in the future. There is no doubt that the effectiveness of environmental protection measures requires a clear and consistent accounting of environmental costs.

Ensuring the sustainable development of the state, its food security, which is the basis of the social well-being of society, is impossible without a highly efficient agricultural sector. A decisive factor in the well-being of the agricultural sector is the availability of effective state regulation mechanisms. The situation in the agro-industrial complex causes reasonable complaints, it was not possible to unlock the export potential and solve the issues of full-fledged food security of the country. It was pointed out the need for a new, verified approach in the agricultural sector, creating conditions for processing raw materials within the country, attracting investment and the latest agricultural technologies, ensuring the stability of state support measures, increasing their effectiveness. Agriculture of Kazakhstan, being one of the priority directions of economic development, has a huge potential and large reserves. The main products of the domestic food and agricultural industry are flour, pasta, rice, meat, dairy products, mineral waters and beverages, sugar and confectionery products, oils and fats. In general, the agricultural sector is characterized by high capital intensity, long payback period, low profitability, dependence on natural and climatic conditions, which makes it less competitive compared to other sectors of the economy.

Membranous nephropathy is an autoimmune disease and one of the most common causes of nephrotic syndrome in adults. The incidence of membranous nephropathy is 1.2 in 100,000 persons per year worldwide. Approximately 80% of patients with membranous nephropathy have a classification of primary (or idiopathic) membranous nephropathy. The treatment goal of patients with primary membranous nephropathy is to induce remission. Current treatment options include calcineurin inhibitors (cyclosporine and tacrolimus), cyclophosphamide, and rituximab.

Rituximab is not approved for the indication of primary membranous nephropathy in Canada. This review aimed to evaluate the evidence on the use of rituximab compared to cyclophosphamide, tacrolimus, and cyclosporine in adult patients with primary membranous nephropathy.

A systematic review of the efficacy and safety of rituximab versus cyclosporine, tacrolimus, or cyclophosphamide was conducted with 18 included randomized controlled trials. A network meta-analysis of 11 of the 18 included randomized controlled trials was uninformative due to the small number of studies, the heterogeneity in the studies, and unreliable point estimates and wide credible intervals obtained with the network meta-analysis.

Due to the uninformative nature of the network meta-analysis, a narrative analysis was conducted of the head-to-head trials of rituximab. Two randomized controlled trials showed no evidence of a difference between rituximab and cyclophosphamide, whereas rituximab resulted in a better response rate (complete remission and the composite outcome of partial or complete remission) at 24 months compared with cyclosporine. There were no head-to-head trials comparing rituximab with tacrolimus.

Given the small network of studies, the heterogeneity in the included studies, and the limited information provided by the network meta-analysis and the pairwise comparisons of the MENTOR and RI-CYCLO trials, CADTH was unable to conduct an informative economic evaluation. Further, in addition to the clinical evidence gaps, there were also issues identifying information to inform key parameters to address the policy question of interest to decision-makers. Given the limitations associated with the clinical evidence and absence of evidence to inform key model parameters, an economic evaluation would not be able to quantify all relevant incremental costs and effects of using rituximab over the currently used alternatives.

The DataHawk2 Uncrewed Aircraft System for Atmospheric Research
Authors: Hamilton Jonathan , de Boer Gijs , Doddi Abhiram , Lawrence Dale
Published: April 2022

Abstract. The DataHawk2 (DH2) is a small, fixed wing uncrewed aircraft system, or UAS, developed at the University of Colorado (CU) primarily for taking detailed thermodynamic measurements of the atmospheric boundary layer. The DH2 weighs 1.7 kg and has a wingspan of 1.3 m, with a flight endurance of approximately 60 minutes, depending on configuration. In the DH2’s most modern form, the aircraft carries a Vaisala RSS-421 sensor for pressure, temperature, and relative humidity measurements, two CU-developed infrared temperature sensors, and a CU-developed finewire array, in addition to sensors required to support autopilot function (pitot tube with pressure sensor, GPS receiver, inertial measurement unit), from which wind speed and direction can also be estimated. This paper presents a description of the DH2, including information on design and development work, and puts the DH2 into context with respect to other contemporary UAS. Data from recent field work (MOSAiC, the Multidisciplinary drifting Observatory for the Study of Arctic Climate) is presented and compared with radiosondes deployed during that campaign to provide an overview of sensor and system performance. These data show good agreement across pressure, temperature, and relative humidity, as well as wind speed and direction. Additional examples of measurements provided by the DH2 are given from a variety of previous campaigns in locations ranging from the continental United States to Japan and northern Alaska. Finally, a look toward future system improvements and upcoming research campaign participation is given.
The Lehtinen–Pirjola method modified for efficient modelling of geomagnetically induced currents in multiple voltage levels of a power network
Authors: Pirjola Risto J. , Boteler David H. , Tuck Loughlin , Marsal Santiago
Published: April 2022

Abstract. The need for accurate assessment of the geomagnetic hazard to power systems is driving a requirement to model geomagnetically induced currents (GIC) in multiple voltage levels of a power network. The Lehtinen–Pirjola method for modelling GIC is widely used but was developed when the main aim was
to model GIC in only the highest voltage level of a power network. Here we present a modification to the Lehtinen–Pirjola (LP) method designed to
provide an efficient method for modelling GIC in multiple voltage levels. The LP method calculates the GIC flow to ground from each node. However,
with a network involving multiple voltage levels, many of the nodes are ungrounded, i.e. have infinite resistance to ground, which is numerically inconvenient. The new modified Lehtinen–Pirjola (LPm) method replaces the earthing impedance matrix [Ze] with the corresponding earthing admittance matrix
[Ye] in which the ungrounded nodes have zero admittance to ground. This is combined with the network admittance matrix [Yn] to give a combined matrix ([Yn] + [Ye]), which is a sparse symmetric
positive definite matrix allowing efficient techniques, such as Cholesky decomposition, to be used to provide the nodal voltages. The nodal voltages
are then used to calculate the GIC in the transformer windings and the transmission lines of the power network. The LPm method with Cholesky
decomposition also provides an efficient method for calculating GIC at multiple time steps. Finally, the paper shows how software for the LP method
can be easily converted to the LPm method and provides examples of calculations using the LPm method.
Evaluating seasonal sea-ice cover over the Southern Ocean at the Last Glacial Maximum

Abstract. Southern hemispheric sea-ice impacts ocean circulation and the carbon exchange between the atmosphere and the ocean. Sea-ice is therefore one of the key processes in past and future climate change and variability. As climate models are the only tool available to project future climate change, it is important to assess their performance against observations for a range of different climate states. The Last Glacial Maximum (LGM, ∼21 000 years ago) represents an interesting target as it is a relatively well-documented period with climatic conditions very different from preindustrial conditions. Here, we analyze the LGM seasonal Southern Ocean sea-ice cover as simulated in numerical simulations as part of the Paleoclimate Modelling Intercomparison Project (PMIP) phases 3 and 4. We compare the model outputs to a recently updated compilation of LGM seasonal Southern Ocean sea-ice cover and summer sea surface temperature (SST) to assess the most likely LGM Southern Ocean state. Simulations and paleo-proxy records suggest a fairly well-constrained glacial winter sea-ice edge between 50.5 and 51∘ S. However, the spread in simulated glacial summer sea-ice is wide, ranging from almost ice-free conditions to a sea-ice edge reaching 53∘ S. Combining model outputs and proxy data, we estimate a likely LGM summer sea-ice edge between 61 and 62∘ S and a mean summer sea-ice extent of 14–15×106 km2, which is ∼20 %–30 % larger than previous estimates. These estimates point to a higher seasonality of southern hemispheric sea-ice during the LGM than today. We also analyze the main processes defining the summer sea-ice edge within each of the models. We find that summer sea-ice cover is mainly defined by thermodynamic effects in some models, while the sea-ice edge is defined by the position of Southern Ocean upwelling in others. For models included in both PMIP3 and PMIP4, this thermodynamic or dynamic control on sea-ice is consistent across both experiments. Finally, we find that the impact of changes in large-scale ocean circulation on summer sea-ice within a single model is smaller than the natural range of summer sea-ice cover across the models considered here. This indicates that care must be taken when using a single model to reconstruct past climate regimes.
Technical Note: Do different projections matter for the Budyko framework?
Authors: Nijzink Remko Christiaan , Schymanski Stanislaus Josef
Published: April 2022

Abstract. The widely used Budyko framework defines the water- and energy-limits of catchments. Generally, catchments plot close to these physical limits and Budyko (1974) developed a curve that predicted the positions of catchments in this framework. The original formulation of the curve had no parameters, but later a more general, parameterized form was adopted. Originally, Budyko defined the independent variable as an aridity index with the potential evaporation divided by the precipitation (Ep / P) and used this to predict the ratio of actual evaporation over precipitation (Ea / P). However, the framework can be formulated in different ways and others defined the framework with the potential evaporation as the common denominator for the dependent and independent variables, i.e. P / Ep and Ea / Ep. It is possible to mathematically convert between these formulations, but if the parameterized Budyko curves are fit to data, the different formulations could lead to differences in the resulting parameter values. Here, we tested this for 357 catchments across the contiguous United States. This was done by fitting a parameterized form of the curve for the two different formulations. In this way, we found that differences in n-values due to the used projection could be +/- 0.2. If robust fitting algorithms were used, instead of a linear least squares algorithm, the differences in n-values reduced, but were nonetheless still present. The distances to the curve, often used as a metric in Budyko-type analyses, systematically dependended on the projection, with larger differences for the side of the framework with Ep / P > 1 for a projection with a dryness index and P / Ep > 1 for a projection with a wetness index (i.e. the non-contracted sides od the framework). When using the two projections for predicting Ea, we found that uncertainties due to the used projections could exceed 1.5 %. An important reason for the differences in n-values, curves and resulting estimates of Ea could be found in datapoints that clearly appear as outliers in one projection, but less so in the other projection. We argue here that the non-contracted side of the framework in the two projections should always be assessed, especially for datapoints that appear as outliers. At least, one should consider the additional uncertainty of the projection and assess the robustness of the results in both projections.

Abstract. Land cover in sub-polar and alpine regions of northern and eastern
Europe have already begun changing due to natural and anthropogenic changes
such as afforestation. This will impact the regional climate and hydrology
upon which societies in these regions are highly reliant. This study aims to
identify the impacts of afforestation/reforestation (hereafter
afforestation) on snow and the snow-albedo effect and highlight potential
improvements for future model development. The study uses an ensemble of
nine regional climate models for two different idealised experiments
covering a 30-year period; one experiment replaces most land cover in Europe
with forest, while the other experiment replaces all forested areas with
grass. The ensemble consists of nine regional climate models composed of
different combinations of five regional atmospheric models and six land
surface models. Results show that afforestation reduces the snow-albedo
sensitivity index and enhances snowmelt. While the direction of change is
robustly modelled, there is still uncertainty in the magnitude of change.
The greatest differences between models emerge in the snowmelt season. One
regional climate model uses different land surface models which shows
consistent changes between the three simulations during the accumulation
period but differs in the snowmelt season. Together these results point to
the need for further model development in representing both grass–snow and
forest–snow interactions during the snowmelt season. Pathways to
accomplishing this include (1) a more sophisticated representation of forest
structure, (2) kilometre-scale simulations, and (3) more observational studies
on vegetation–snow interactions in northern Europe.
Quantifying climate model representation of the wintertime Euro-Atlantic circulation using geopotential-jet regimes
Authors: Dorrington Joshua , Strommen Kristian , Fabiano Federico
Published: April 2022

Abstract. Even the most advanced climate models struggle to reproduce the observed wintertime circulation of the atmosphere over the North Atlantic and western Europe. During winter, the large-scale motions of this particularly challenging region are dominated by eddy-driven and highly non-linear flows, whose low-frequency variability is often studied from the perspective of regimes – a small number of qualitatively distinct atmospheric states. Poor representation of regimes associated with persistent atmospheric blocking events, or variations in jet latitude, degrades the ability of models to correctly simulate extreme events. In this paper we leverage a recently developed hybrid approach – which combines both jet and geopotential height data – to assess the representation of regimes in 8400 years of historical climate simulations drawn from the Coupled Model Intercomparison Project (CMIP) experiments, CMIP5, CMIP6, and HighResMIP. We show that these geopotential-jet regimes are particularly suited to the analysis of climate data, with considerable reductions in sampling variability compared to classical regime approaches. We find that CMIP6 has a considerably improved spatial regime structure, and a more trimodal eddy-driven jet, relative to CMIP5, but it still struggles with under-persistent regimes and too little European blocking when compared to reanalysis. Reduced regime persistence can be understood, at least in part, as a result of jets that are too fast and eddy feedbacks on the jet stream that are too weak – structural errors that do not noticeably improve in higher-resolution models.
Barreras y factores facilitadores para la accesibilidad a la interrupción legal del embarazo (ILE) en el subsistema privado y de la seguridad social de Argentina: análisis de la situación institucional en el Hospital Italiano de Buenos Aires

Hasta diciembre de 2020, en Argentina el aborto era legal ante determinadas causales. Sin embargo, era común que la implementación de esta legislación se viera entorpecida. El objetivo de esta investigación fue identificar las barreras y los factores facilitadores para la accesibilidad a la interrupción legal de embarazo en una institución del subsistema privado y de la seguridad social. Se realizó una investigación con enfoque cualitativo con entrevistas a profesionales del equipo de salud involucrados en el circuito de atención de interrupción legal de embarazo del Hospital Italiano de Buenos Aires. Los resultados se organizan en cinco ejes temáticos que surgieron luego de un proceso de lectura, interpretación y discusión: 1) ausencia de una política institucional explícita, 2) los componentes de la práctica (falta de registro en la historia clínica electrónica, desarrollo de  circuitos paralelos para acceder a la medicación: misoprostol), 3) el marco jurídico legal y las causales (falta de leyes claras, diversas interpretaciones en lo que respecta al causal salud), 4) la objeción de conciencia y 5) los aspectos contextuales (movimiento feminista, el proyecto de ley desaprobado en el senado en 2018). A pesar de que el equipo de salud contaba con un marco legal claro, implementar una política institucional interna resulta sumamente necesario.
Siglo XXI, tiempo de inclusión: llega el momento de revisar la categoría género en la práctica clínica
Authors: Discacciati Vilda
Published: April 2022

Un reciente artículo publicado por Fuerza de Tareas de Servicios Preventivos de EE.UU. (en inglés, USPSTF), comunicó los resultados de una revisión enfocada a identificar cuestiones vinculadas a la perspectiva de género en la elaboración de las recomendaciones que esta institución emite regularmente. En esa publicación los autores reconocieron que el sexo biológico y la identidad de género no son habitualmente tenidos en cuenta en los estudios de investigación, lo que constituye una barrera para implementar recomendaciones que optimicen una práctica clínica inclusiva. A partir de esa comunicación, la autora de este artículo editorial considera aspectos vinculados con el género que se reflejan en nuestro pensamiento, lenguaje y abordaje clínico, situándolos en el contexto de los cambios culturales y normativos sucedidos en Argentina durante las últimas dos décadas.

En una serie de artículos, el equipo PROFAM comparte su punto de vista a través de una adaptación de su material educativo sobre la IVE. En esta primera entrega, las autoras abordan la aplicación de las cuestiones legales que determinan la práctica, la consejería general, y algunos lineamientos de cómo actuar ante la situación de un diagnóstico de embarazo inesperado.
Adjusted Landing Technique Reduces the Load on the Achilles Tendon in Badminton Players

Published: April 2022

Achilles tendon (AT) rupture is common among recreational male badminton players. We hypothesize that a landing technique following forehand jump strokes with the landing foot in a neutral position often performed by recreational players and occasionally by elite players may expose the AT to higher loads than a scissor kick jump (SKJ) technique with the leg/foot externally rotated. The study aimed to investigate if recreational players could reduce the load in the AT when adopting the SKJ technique compared to their habitual landing technique with the foot in a neutral position and secondarily to compare the AT force between recreational players and elite players. Ten recreational male players performed simulated jump strokes in a biomechanical laboratory using both their original technique and the SKJ technique traditionally used by elite players. For comparison reasons ten elite players performed SKJs. Landing kinematics and AT forces were captured and calculated using 3D movement analysis. The landing leg was more externally rotated in the recreational players' adjusted technique (78 ± 10 degrees, p < 0.001) compared to 22 ± 21 degrees in recreational players' original technique. The peak AT force of the recreational players was significantly higher for the original technique compared to the adjusted technique (68 ± 19 N/kg vs. 50 ± 14 N/kg, p = 0.005). Additionally, the peak AT forces observed during the recreational players’ original technique was higher, though not significantly, than those observed for elite players (55 ± 11 N/kg, p = 0.017). / = 0.016 due to a Bonferroni correction. These findings indicate that recreational badminton players that normally land with the foot in a neutral position, may reduce their AT load by 25% when adopting the SKJ technique of elite players and land with the leg/foot in an externally rotated position.
