Abstract. General circulation models' (GCMs) estimates of the liquid water path adjustment to anthropogenic aerosol emissions differ in sign from other lines of evidence. This reduces confidence in estimates of the effective radiative forcing of the climate by aerosol–cloud interactions (ERFaci). The discrepancy is thought to stem in part from GCMs' inability to represent the turbulence–microphysics interactions in cloud-top entrainment, a mechanism that leads to a reduction in liquid water in response to an anthropogenic increase in aerosols. In the real atmosphere, enhanced cloud-top entrainment is thought to be the dominant adjustment mechanism for liquid water path, weakening the overall ERFaci. We show that the latest generation of GCMs includes models that produce a negative correlation between present-day cloud droplet number and liquid water path, a key piece of observational evidence supporting liquid water path reduction by anthropogenic aerosols and one that earlier-generation GCMs could not reproduce. However, even in GCMs with this negative correlation, the increase in anthropogenic aerosols from preindustrial to present-day values still leads to an increase in simulated liquid water path due to the parameterized precipitation-suppression mechanism. This adds to the evidence that correlations in the present-day climate are not necessarily causal. We investigate sources of confounding to explain the noncausal correlation between liquid water path and droplet number. These results are a reminder that assessments of climate parameters based on multiple lines of evidence must carefully consider the complementary strengths of different lines when the lines disagree.
Extremely warm European summers preceded by sub-decadal North Atlantic ocean heat accumulation
Authors: Wallberg Lara , Suarez-Gutierrez Laura , Matei Daniela , Müller Wolfgang A.
Published: January 2024

Abstract. The internal variability of European summer temperatures has been linked to various mechanisms on seasonal to sub- and multi-decadal timescales. We find that sub-decadal timescales dominate summer temperature variability over large parts of the continent and determine mechanisms controlling extremely warm summers on sub-decadal timescales. We show that the sub-decadal warm phases of bandpass-filtered European summer temperatures, hereinafter referred to as extremely warm European summers, are related to a strengthening of the North Atlantic Ocean subtropical gyre, an increase in meridional heat transport, and an accumulation of ocean heat content in the North Atlantic several years prior to the extreme summer. This ocean warming affects the ocean–atmosphere heat fluxes, leading to a weakening and northward displacement of the jet stream and increased probability of occurrence of high-pressure systems over Scandinavia. Thus, our findings link the occurrence of extremely warm European summers to the accumulation of heat in the North Atlantic Ocean and provide the potential to improve the predictability of extremely warm summers several years ahead, which is of great societal interest.

Abstract. Total alkalinity (AT) and dissolved inorganic carbon (CT) in the oceans are important properties with respect to understanding the ocean carbon cycle and its link to global change (ocean carbon sinks and sources, ocean acidification) and ultimately finding carbon-based solutions or mitigation procedures (marine carbon removal). We present a database of more than 44 400 AT and CT observations along with basic ancillary data (spatiotemporal location, depth, temperature and salinity) from various ocean regions obtained, mainly in the framework of French projects, since 1993. This includes both surface and water column data acquired in the open ocean, coastal zones and in the Mediterranean Sea and either from time series or dedicated one-off cruises. Most AT and CT data in this synthesis were measured from discrete samples using the same closed-cell potentiometric titration calibrated with Certified Reference Material, with an overall accuracy of ±4 µmol kg−1 for both AT and CT. The data are provided in two separate datasets – for the Global Ocean and the Mediterranean Sea (https://doi.org/10.17882/95414, Metzl et al., 2023), respectively – that offer a direct use for regional or global purposes, e.g., AT–salinity relationships, long-term CT estimates, and constraint and validation of diagnostic CT and AT reconstructed fields or ocean carbon and coupled climate–carbon models simulations as well as data derived from Biogeochemical-Argo (BGC-Argo) floats. When associated with other properties, these data can also be used to calculate pH, the fugacity of CO2 (fCO2) and other carbon system properties to derive ocean acidification rates or air–sea CO2 fluxes.
Regional-scale landslide risk assessment in Central Asia
Authors: Caleca Francesco , Scaini Chiara , Frodella William , Tofani Veronica
Published: January 2024

Abstract. Landslides are widespread phenomena that occur in any terrestrial area with slopes, causing massive property damage and, in the worst-case scenario, loss of human life. This propensity to suffer losses is particularly high for developing countries due to their urban development, population growth and drastic land use changes. Social and economic consequences of landslides can be reduced through detailed planning and management strategies, which can be aided by risk analysis. In this study, we performed a detailed quantitative risk analysis for landslides in the whole of Central Asia (4 000 000 km2). Landslide-induced risk was computed, using a 200 m spatial resolution, in terms of exposed population and expected economic losses to buildings and linear infrastructures (roads and railways). The purpose of our study is to produce the first regional-scale landslide risk assessment for Central Asia in order to inform regional-scale risk mitigation strategies, and it represents an advanced step in the landslide risk analysis for extremely broad areas.
Seismic attenuation in Antarctic firn
Authors: Picotti Stefano , Carcione José M. , Pavan Mauro
Published: January 2024

Abstract. We estimate the seismic attenuation of P and S waves in the polar firn and underlying ice by spectral analysis of diving, refracted, and reflected waves from active-source three-component seismic signals obtained in 2010 on the Whillans Ice Stream (WIS), a fast-flowing ice stream in West Antarctica. The resulting quality factors are then successfully modeled using a rock-physics theory of wave propagation that combines White's mesoscopic attenuation theory of interlayer flow with that of Biot/squirt flow. The first theory describes an equivalent viscoelastic medium consisting of a stack of two alternating thin porous layers, both of which have thicknesses that are much greater than the pore size but smaller than the wavelength. On the other hand, in the so-called Biot/squirt-flow model, there are two loss mechanisms, namely the global Biot flow and the local flow from fluid-filled microcracks (or grain contacts) to the pore space and back, where the former is dominant over the latter. The fluid saturating the pores is assumed to be fluidized snow, defined as a mixture of snow particles and air, such as powder, with a rigidity modulus of zero.
Impact of shallow sills on circulation regimes and submarine melting in glacial fjords
Authors: Bao Weiyang , Moffat Carlos
Published: January 2024

Abstract. The increased melting and rapid retreat of marine-terminating glaciers is a key contributor to sea-level rise. In glacial fjords with shallow sills common in Patagonia, Alaska, and other systems, these bathymetric features can act as a first-order control on the dynamics. However, our understanding of how this shallow bathymetry interacts with the subglacial discharge from the glacier and impacts the fjord circulation, water properties, and rates of submarine melting is limited. To address this gap, we conduct idealized numerical simulations using a coupled plume–ocean fjord model spanning a wide range of initial ocean conditions, sill depths, and subglacial discharge. A previously documented circulation regime leads to strong mixing and vertical transport over the sill, where up to ∼ 70 % of the colder water from the upper-layer outflow is refluxed into the deeper layer, cooling the incoming warm oceanic water by as much as 1 ∘C and reducing the stratification near the glacier front. When the initial stratification is relatively strong or the subglacial discharge is relatively weak, an additional unsteady circulation regime arises where the freshwater flow can become trapped below the sill depth for weeks to months, creating an effective cooling mechanism for the deep water. We also find that submarine melting often increases when a shallow sill is added to a glacial fjord due to the reduction of stratification – which increases submarine melting – dominating over the cooling effect as the oceanic inflow is modified by the presence of the sill. These results underscore that shallow-silled fjords can have distinct dynamics that strongly modulate oceanic properties and the melting rates of marine-terminating glaciers.

Authors: Amrutha T.A , A.K Beena
Published: January 2024

The present study attempted to evaluate the effect of incorporating an exopolysaccharide (EPS) producing indigenous strain of lactic acid bacteria (LAB) with a non-EPS producing industrial strain of LAB on the physico-textural properties of product. For this, characteristics of the skim milk coagulum prepared using monocultures and mixed cultures were determined and compared. EPS producing Pediococcus pentosaceus DMG01as well as the non-EPS producer Lactococcus lactis were graded as weak acid producer based on Horrall Elliker test. Ability of the isolate DMG01 to ferment citrate endorsed its flavour production potential. Colony characteristics in Congo red agar indicated the indigenous isolate to be an EPS producer and industrial stain a non-EPS producer. The treatment products were prepared using EPS negative LAB (A), EPS producing P.pentosaceus (B) and a combination of these in the ratio 1:1 (C). The titratable acidity of curd B (0.96 percent LA) and curd A (0.86 per cent LA ) was significantly less than C (1.10 per cent LA). In line with the titratable acidity, pH differed significantly between the treatments. Syneresis value of A (1.72 per cent) was significantly higher than both B (1.55 per cent) and C (1.28 per cent). Penetrometer reading was also significantly higher for A (36.25mm), indicating that the curd tension of the A was significantly lower than both B and C. Scanning electron microscopy revealed extensive fusion of casein micelles in milk coagulum prepared with EPS producing starter culture. The results underscore the advantageous effect of EPS producing starters on textural characteristics of the fermented product.

Pyoderma, refers to any clinical picture that results in the accumulation of neutrophilic exudates of varying degrees in conjunction with a bacterial infection. A longitudinal study was conducted among 178 dogs brought to the small animal dermatology unit of Teaching Veterinary Clinical Complex, Mannuthy and University Veterinary Hospital, Kokkalai, Thrissur, Kerala to document the age, breed and sex predispositions and to identify any environmental influence or managemental practice that predisposes to pyoderma. The overall prevalence of pyoderma was 7.5 per cent. Statistical analyses using Chi square test revealed that there was significant difference in the proportion of animals affected with pyoderma among different categories of age, breed, housing system, bathing practices, kennel hygiene, access to oral coat conditioners and feed supplements. The distribution of animals affected with pyoderma was statistically significant between different seasons also. The condition was commonest in dogs between one to three years of age (46.07 per cent). The Labrador retrievers were more predisposed to developing pyoderma. More females (53.37 per cent) were infected when compared to males (46.63 per cent). Majority of the cases (52.25 per cent) were housed outdoors in a separate kennel and were bathed (68.54 per cent) regularly and groomed (36.52 per cent) at least once a month. The analyses of the epidemiological profile of dogs affected with pyoderma revealed that apart from the host factors, the environmental and managemental aspects also plays an important role in the occurrence of pyoderma.

Rabies is an acute fatal encephalitis known to mankind ever since the dawn of human civilization. Dogs act as the principal vector for transmission of rabies in India. Direct fluorescent antibody test on brain sample is the gold standard test recommended for diagnosis of rabies. The present study was designed to compare immunofluorescence for rabies in different anatomical sites of brain by employing direct fluorescent antibody test (DFAT). Impression smears from cerebrum, cerebellum, hippocampus and brainstem of 30 rabies positive dogs were subjected to grading and comparative evaluation of immunofluorescence upon DFAT. The impression smears from these sites were subsequently graded from 1+ to 4+ based on intensity and distribution of fluorescence. The results revealed that brainstem and cerebellum showed almost similar and higher grades of fluorescence followed by hippocampus and cerebrum. The study also unveiled unilateral distribution of viral antigen in the hippocampus in certain cases which questions the reliability of employing hippocampal smears for DFAT. The study concluded that brainstem and cerebellum are the preferred samples for DFAT for rabies in canines.

The present study was carried out to assess the influence of three seasons in Kerala on the yield and quality of oocytes from crossbred (CB) dairy cows (n=27), subjected to ultrasound-guided transvaginal oocyte recovery (TVOR). Meteorological data including, ambient temperature (AbT) and relative humidity (RH) was recorded and Temperature Humidity Index (THI) was calculated. In each season, selected animals (n=9) were subjected to TVOR; data regarding the number of follicles available for puncture (>2mm), number of aspirated follicles, number of oocytes retrieved and oocyte recovery rate were recorded. The retrieved oocytes were subjected to morphological evaluation. Significantly higher (P<0.05) AbT and THI was recorded during summer (28.92±0.64oC and 80.61±0.76) when compared to rainy (26.95±0.17oC and 78.68±0.21) and post-monsoon (27.29±0.22 oC and 77.75 ± 0.57) seasons. However, due to the availability of rainfall throughout the year, RH did not differ significantly between seasons. The mean number of follicles imaged (available for puncture) by ultrasonography per session was significantly higher (P<0.01) during the rainy season (11.19±0.74) compared to post-monsoon (8.08±0.47) and summer (5.28±0.38). Total mean number of follicles aspirated and oocytes retrieved per session was highest during rainy season (7.86±0.49 and 3.17±0.28) and least during summer (4.36±0.29 and 1.81±0.20). However, the oocyte recovery rate and the yield of culture-grade oocytes did not differ significantly between seasons. It was observed that the THI during all the seasons was above the thermo-comfortable level suggested for dairy cows. Ovarian activity of CB dairy cows was compromised during the summer season in Kerala, as evidenced by the lowest number of follicles aspirated and oocytes retrieved per session.

Published: January 2024

The search for alternative therapeutics is on the rise on account of widespread bacterial resistance to numerous conventional antibiotics. Bioactive peptides produced by lactic acid bacteria found in natural sources such as fermented dairy products have attracted attention as a possible source of biotherapeutic peptides. Bioactive peptides released in fermented milk, on the other hand, is dependent on the proteolytic activities of the cultures used. As a result, this study was carried out to evaluate the effect of fermentation on antibacterial activity of milk from Vechur and Kasargod Dwarf cattle against pathogenic bacteria during 21-days storage period at 5°C. High-speed centrifugation was used to create water-soluble crude peptide extracts. The water-soluble peptides from Kasargod Dwarf and Vechur cattle by fermentation showed maximum inhibition against Escherichia coli NCIM2685 and Salmonella enterica ATCC 6017. The zone of inhibition measured ranges from 5mm to 11mm throughout the storage period. However, both did not show zone of inhibition against Bacillus cereus ATCC 10876 and Staphylococcus aureus ATCC 25923 during 21 days of storage at pH 7.4.

Published: January 2024

Caprine respiratory mycoplasmosis is a major problem in India. Various mycoplasma species cause pneumonia and respiratory problems, thus inflicting huge economic losses in the small ruminant production sector. Though multiple species cause respiratory mycoplasmosis, data regarding species prevalence is deficient in India. The present study was conducted to study the prevalence of respiratory mycoplasmosis caused by Mycoplasma ovipneumoniae in goats using polymerase chain reaction (PCR). A total of 98 nasal swabs were collected, out of which 44 samples were positive for M. ovipneumoniae. A total of 26 animals with explicit clinical signs were selected for comparing the therapeutic efficacy of marbofloxacin and tylosin and were randomly divided into two groups consisting of 13 animals each. Group 1 was treated with marbofloxacin @ 2mg/kg body weight, intramuscularly for 5 days. Group 2 was treated with tylosin @ 10mg/kg body weight, intramuscularly for 5 days. Complete bacteriological recovery rate in group 1 and group 2 was observed as 69.2 per cent and 84.6 per cent respectively by day 11 of treatment. Statistical analysis revealed that marbofloxacin was as effective as tylosin against respiratory mycoplasmosis in goats.

Measurements of the distal femur are highly variable among different subjects. To obtain the best stability and longevity of the knee implants, anthropometric data of the distal femur is required. The aim of this study was to investigate the anatomical structure of the distal femur according to age and gender and to determine the changes in the groups, of the patients with meniscopathy and controls. A total of 488 patients were included in the study according to age groups (0-15, 16-30, 31-45, 46-60, 61 and above). Intercondylar width, intercondylar anteroposterior distance, medial condylar width, lateral condylar width, bicondylar width, medial condyle anteroposterior distance, and lateral condyle anteroposterior distance were measured on axial Magnetic Resonance Imaging (MRI). Intercondylar width, medial condylar width, lateral condylar width and bicondylar width were significantly higher in men in all age groups compared to women (p < 0.05). Intercondylar anteroposterior distance, medial condyle anteroposterior distance and lateral condyle anteroposterior distance were statistically significantly higher in males than in females except 0-15 age group (p < 0.05). There was no significant difference in medial and lateral anteroposterior distance values in men (p > 0.05), and found to be statistically significant (p < 0.05) on the right and left side in women. Although personalized implant production is expensive compared to today’s conditions, we think that age and gender changes should be considered in the selection of prosthesis, since the dimensions of the distal femur will affect the stability and duration of use of knee implants.

Published: January 2024

Los trabajos arqueológicos realizados en La Peña del Castro han sacado a la luz un poblado ocupado desde la Primera Edad del Hierro hasta el cambio de Era. La destrucción violenta del asentamiento durante la conquista romana ha permitido documentar de manera excepcional la última fase de ocupación, comprendida entre los siglos ii- i a. C. Gracias a los derrumbes y al incendio que arrasó el poblado, se han conservado elementos estructurales de madera carbonizada, así como restos de la arquitectura en barro y el alzado de algunas construcciones. En el presente trabajo se analizan las técnicas y materiales utilizados en las construcciones, así como las implicaciones socioeconómicas de las mismas. Para ello se ha realizado un análisis multidisciplinar integrando diferentes materiales, así como la descripción de las diferentes unidades arquitectónicas y de sus técnicas constructivas.

Published: January 2024

The article presents the results of studying the indicators of the crumbling of granules and the specific energy costs of experimental batches of granulated feed for broilers. The process of granulation of compound feed for broilers was studied using the statistical planning method of a multifactorial experiment using a granulation line, including a granulator press. The dependence of the crumbling of granules and the energy consumed on the selected factors has been established. The moisture content of the feed mixture W (%) and steam pressure P (MPa) were chosen to optimise the granulation process. A matrix plan of the experiment was compiled. With the optimal values of the factors obtained in the study using the experimental planning method, an experimental batch of granulated feed was developed. At the selected levels of factors, the calculated value of the crumbling of granules was 20.11%, which fits into the optimum according to the standard of the crumbling of granulated feed for poultry (no more than 22%). The specific electricity consumption was 9.23 kWh/ton. Experiments have shown that the discrepancies between the experimental and calculated data are insignificant and within these indicators' experimental error determination. Mathematical modelling of the granulation process of loose compound feed for broilers made it possible to solve an important practical problem – to optimize the granulation mode, which ensures the production of good quality granules with minimal energy consumption. The obtained optimal granulation parameters can serve as the basis for producing granulated feed for broilers.

Inside the Nucleon: Tomographic Interpretations and Universality of GPDs with DDVCS
Authors: Yuan Melinda , Robbins Jocelyn
Published: January 2024

The goal of Double Deeply Virtual Compton Scattering (DDVCS) experiments is to better understand the internal structure of the nucleon. Previous attempts to resolve the internal structure of nucleons have resulted in electromagnetic form factors and parton distribution functions for elastic scattering and deep inelastic scattering processes, respectively. Generalized Parton Distributions (GPDs) are the latest attempt to unify these models of nucleon structure. The GPDs of DDVCS give us ability to investigate off of the diagonal where x ̸= ±ξ. The main goal of our analysis is to determine the best experimental setup in order to deduce the kinematic variables on which GPDs depend from the lab observables. The effectiveness of our data collection in the laboratory is by determined the physical kinematics, Q2, Q′2,t, xi,ϕLM, ϕCMV , and θCMV . We can then run DDVCS experiments and collect data on observables to improve upon the current models for GPDs of the nucleon.

Background: Deaths caused by smoking are very worrying, in the world as many as 225,700 people die from tobacco every year according to WHO in 2020 (Abdulateef, 2016; Alinaggar, 2011). Tobacco use in Indonesia aged over 15 years. It has increased again from the previous year, namely 28.96% (Alamsyah, 2017; Binita, 2016), and is still dominated by men at 7.14% Alamsyah, (21017). Smoking habits in teenagers due to misunderstanding of information, influence of advertising and influence of friends. In society, smoking is a measure of maturity level so teenage boys follow this behavior. The beginning of smoking behavior is caused by a community environment where the majority smoke and the invitation of friends to smoke (Huriyati, 2016; Izzati, 2016).
Methods: participatory training and role-play are the methods used, starting from community formation, namely optimizing the role of cadres in the smoking cessation program. The next stage is education about smoking and training for administrators and cadres to stop smoking. The final stage is a follow-up to the smoking cessation program which will be carried out independently by cadres and evaluations carried out regularly by cadres.
Results: Participants' knowledge about smoking was very diverse. During the activity, the participants had a high motivational interest. The enthusiasm of the counseling participants is a very good start to increasing insight. The level of knowledge of participants increased by up to 40% after the outreach activities were carried out.
Conclusion: Providing counseling can increase students' knowledge about quitting smoking by 40% based on the results of the pre-test and post-test. The formation of a community smoking cessation program consisting of young students who volunteer to accompany their friends to quit smoking.

This study investigated adolescents’ (secondary school students, N = 145, M age 13.9 years) historical reasoning skills when analyzing and interpreting an image. Presumably, historical reasoning can be fostered when engaging in inquiry-based writing. However, in past research using inquiry-based writing tasks, textual sources rather than images prevailed. The present research investigated students’ writing skills when interpreting a historical image. Participants were presented with a historical photograph and were asked to write a structured text about their analysis and interpretation of this image. A scoring rubric was developed to assess the quality of students’ historical reasoning skills, specifically: (1) asking and answering historical questions, (2) reasoning about images, and (3) reasoning with images. Findings show that the factor structure of the scoring rubric largely overlaps with theoretically distinguished components of historical reasoning. Students were able to ask historical questions and write a well-structured text. However, most students did not describe and analyze the source of the image and did not refer to the main message of the image. Further, many students could not identify the image’s relevance for the present. Importantly, the findings imply that students’ methodological competencies to critically analyze and interpret the used image were not elaborated. Possibly, they do not receive sufficient training addressing these skills. This seems problematic, not only in history education but also when deriving meaning from images in everyday life.

Authors: Troche Avelina Victoria , Samudio Margarita
Published: January 2024

Introducción: La glomerulonefritis pos infecciosa (GNPI) en la infancia es un factor de riesgo para el desarrollo de enfermedad renal crónica a largo plazo. La adherencia al control médico permite realizar la nefroprevención secundaria. Objetivo: evaluar la relación entre los factores de riesgo relacionados a la falta de adherencia al control médico de pacientes con GNPI en una cohorte pediátrica. Metodología: estudio descriptivo de asociación cruzada de cohorte retrospectiva de pacientes internados entre enero de 2000 a diciembre de 2018 en un hospital de referencia. Se analizó la relación entre: hacinamiento, colecho, escolaridad materna y paterna, número de hermanos, de convivientes y procedencia, con la falta de adherencia al control médico. Se utilizaron la prueba de chi cuadrado y regresión logística a un nivel de significancia de 0,05. Resultados: Se incluyeron 148 pacientes (103 niños y 45 niñas) entre 2 a 16 años (edad promedio: 8,5± 3,4 años). La falta de adherencia fue encontrada en 73 pacientes (49,3%) que se asoció a procedencia rural (p= 0,012, RR: 1,50, IC95%: 1,10-2,06), baja escolaridad materna (p= 0,046, IC95%: 1,54:1,14-2,08), baja escolaridad paterna (p= 0,02; RR: 1,483, IC95%: 1,09-2,01), >3 convivientes (p=0,007, RR: 1,630, IC95%: 1,21-2,19), colecho (p=0,026; RR: 1,52, IC95%: 1,02-2,27) y hacinamiento (p<0,0001; RR: 1,92, IC95%: 1,39-2,65). Por regresión logística, el hacinamiento (p=0,005; OR= 4,8) y procedencia rural (p=0,022; OR: 2,4) se mantuvieron asociados a la falta de adherencia. Discusión: El hacinamiento y la procedencia rural se asociaron en forma independiente con la pérdida de seguimiento. Se recomienda mayor intervención de la atención primaria de salud.
Barreras de acceso a los servicios primarios de salud sexual y reproductiva en adolescentes, de una comunidad urbano marginal del Perú
Authors: Ypanaque Ancajima Jhon Edwin
Published: January 2024

Introducción: Las barreras de acceso a los servicios de salud primario conforman estructuras sociales que agravan la situación de salud de los adolescentes, impactando negativamente en el ejercicio pleno de la salud sexual reproductiva, situando a los adolescentes en una población de riesgo social. Objetivo: Determinar las barreras en el acceso a los servicios primarios de Salud Sexual y Reproductiva de atención diferenciada a los adolescentes del Centro de Salud I – 4 Pampa Grande Tumbes 2018. Metodología: Estudio analítico de caso control, se entrevistaron a 288 adolescentes del tercero, cuarto y quinto de secundaria de la institución educativa pública Túpac Amaru del centro poblado Pampa Grande de Tumbes en el año 2019, entre experimento y control con una razón de 1 a 1.  Se aplicaron cuestionarios anónimos para evaluar las barreras de accesibilidad a los servicios primarios de salud. Se recogieron variables:  características sociodemográficas y culturales que son consideradas, como barreras de acceso a los servicios de salud. Se realizó un análisis descriptivo e inferencial con el programa SPSS® v.23. Resultados: La edad, sexo e ingreso económico están directa y significativamente relacionadas con la accesibilidad a los servicios de salud sexual y reproductiva (p<0.01 IC 95 %); La disposición de recursos económicos para asumir los costos de traslado al centro de salud (OR = 4,23); la utilización del transporte público (OR = 1,58), el conocimiento de los servicios de salud sexual y reproductiva (OR = 1,15) incrementan la probabilidad de acceder a los servicios de salud sexual y reproductiva de los adolescentes. Discusión: Las barreras socioeconómicas a los servicios de salud sexual y reproductiva de los adolescentes son modificables y dependen de la gestión en salud pública.

Published: January 2024

Introducción: Paraguay asumió el reto de lograr cobertura universal mediante redes basadas en Atención Primaria de la Salud con Unidades de Salud de la Familia (USF) en el primer nivel de atención. Un desafío es la atención integral ante enfermedades no transmisibles, principal causa de mortalidad en el país.  Objetivo: analizar la capacidad de las USF para la atención de personas con hipertensión arterial y diabetes en el sistema nacional de salud. El diseño fue no experimental, cuantitativo, transversal, descriptivo con componente analítico. Metodología: Incluyó a 761 USF de 12 regiones sanitarias agrupados en 4 ejes territoriales. Se adaptó el método de evaluación SARA de la OMS con 75 variables, aplicando un cuestionario a profesionales de salud entre noviembre y diciembre de 2022. Se calculó índices de disponibilidad y preparación así como un índice que los integra. La medida continua de estos índices se categorizó en 3 grupos: suficiente >0,75 a 1; intermedio 0,5 a 0,75 y bajo <0,5. Resultados: Solo en el 38 % de las USF el índice de disponibilidad fue suficiente, en el 31,5 %  para el índice de preparación y en el 31,1 % para el índice integrador SARA DM/HTA. El desempeño se asoció de forma significativa con el eje territorial no así con el área ni con la cobertura a población indígena Discusión: las USF presentaron limitaciones para la atención de personas con diabetes e hipertensión en estas regiones del país.

Inertia I: The global MSp-SUSY induced uniform motion
Authors: Ter-Kazarian G.
Published: January 2024

In this communication our main emphasis is on the review of the foundations of standard Lorentz code (SLC) of a particle motion. To this aim, we develop the theory of global, so-called, `double space´- or master space (MSp)-supersymmetry, subject to certain rules, wherein the superspace is a 14D-extension of a direct sum of background spaces M4⊕ MSp by the inclusion of additional 8D fermionic coordinates. The latter is induced by the spinors θ and ¯θ referred to MSp. While all the particles are living on M4, their superpartners can be viewed as living on MSp. This is a main ground for introducing MSp, which is unmanifested individual companion to the particle of interest. Supersymmetry transformation is defined as a translation in superspace, specified by the group element with corresponding anticommuting parameters. The multiplication of two successive transformations induce the motion. As a corollary, we derive SLC in a new perspective of global double MSp-SUSY transformations in terms of Lorentz spinors (θ, ¯θ). This calls for a complete reconsideration of our ideas of Lorentz motion code, to be now referred to as the individual code of a particle, defined as its intrinsic property. In MSp-SUSY theory, obviously as in standard unbroken SUSY theory, the vacuum zero point energy problem, standing before any quantum field theory in M4, is solved. The particles in M4 themselves can be considered as excited states above the underlying quantum vacuum of background double spaces M4⊕ MSp, where the zero point cancellation occurs at ground-state energy, provided that the natural frequencies are set equal (q 2 0 ≡ νb = νf ), because the fermion field has a negative zero point energy while the boson field has a positive zero point energy. On these premises, we derive the two postulates on which the Special Relativity (SR) is based.
