HSF3 and Hsp70 Expression during Post-Hatch Cold Stress in Broiler Chickens Subjected to Embryonic Thermal Manipulation
Authors: Tarkhan Amneh , Saleh Khaled , Al-Zghoul Mohammad
Published: April 2020

Decades of selective breeding for commercial purposes have rendered the broiler chicken (Gallus gallus domesticus) highly susceptible to heat and cold stress. A multitude of studies have documented the effects of thermal manipulation (TM) on broiler thermotolerance during periods of post-hatch heat stress, but very few have focused on the effect of TM on a broiler’s ability to withstand cold stress. Therefore, the primary objective of the current study is to determine the effects of TM on the acquisition of thermotolerance in broilers via their expression of the stress-associated 70 kilodalton heat shock protein (Hsp70) gene and heat shock factor 3 (HSF3) gene. Briefly, Hubbard broiler embryos were subject to TM by increasing the incubation temperature to 39 °C and 65% relative humidity (RH) for 18 h daily, from embryonic days (ED) 10 to 18. Broilers were then exposed to cold stress by decreasing the room temperature to 16 °C during post-hatch days 32 to 37. After thermal challenge, broilers were euthanized and hepatic and splenic tissues were collected. Our results showed that TM decreased the hatchability rate and body temperature but improved the body weight gain. TM generally decreased the hepatic expression but did not change the splenic expression of HSF3 during cold stress. In contrast, both hepatic and splenic Hsp70 expression decreased during cold stress. The results of the present study may suggest that TM significantly affects a broiler’s genetic response to cold stress.

Published: April 2020

Rainfall-induced landslides are among the most devastating natural disasters in hilly terrains and the reduction of the related risk has become paramount for public authorities. Between the several possible approaches, one of the most used is the development of early warning systems, so as the population can be rapidly warned, and the loss related to landslide can be reduced. Early warning systems which can forecast such disasters must hence be developed for zones which are susceptible to landslides, and have to be based on reliable scientific bases such as the SIGMA (sistema integrato gestione monitoraggio allerta—integrated system for management, monitoring and alerting) model, which is used in the regional landslide warning system developed for Emilia Romagna in Italy. The model uses statistical distribution of cumulative rainfall values as input and rainfall thresholds are defined as multiples of standard deviation. In this paper, the SIGMA model has been applied to the Kalimpong town in the Darjeeling Himalayas, which is among the regions most affected by landslides. The objectives of the study is twofold: (i) the definition of local rainfall thresholds for landslide occurrences in the Kalimpong region; (ii) testing the applicability of the SIGMA model in a physical setting completely different from one of the areas where it was first conceived and developed. To achieve these purposes, a calibration dataset of daily rainfall and landslides from 2010 to 2015 has been used; the results have then been validated using 2016 and 2017 data, which represent an independent dataset from the calibration one. The validation showed that the model correctly predicted all the reported landslide events in the region. Statistically, the SIGMA model for Kalimpong town is found to have 92% efficiency with a likelihood ratio of 11.28. This performance was deemed satisfactory, thus SIGMA can be integrated with rainfall forecasting and can be used to develop a landslide early warning system.

Published: April 2020

With climate change and urban development, water systems are changing faster than ever. Currently, the ecological status of water systems is still judged based on single point measurements, without taking into account the spatial and temporal variability of water quality and ecology. There is a need for better and more dynamic monitoring methods and technologies. Aquatic drones are becoming accessible and intuitive tools that may have an important role in water management. This paper describes the outcomes, field experiences and feedback gathered from the use of underwater drones equipped with sensors and video cameras in various pilot applications in The Netherlands, in collaboration with local water managers. It was observed that, in many situations, the use of underwater drones allows one to obtain information that would be costly and even impossible to obtain with other methods and provides a unique combination of three-dimensional data and underwater footage/images. From data collected with drones, it was possible to map different areas with contrasting vegetation, to establish connections between fauna/flora species and local water quality conditions, or to observe variations of water quality parameters with water depth. This study identifies opportunities for the application of this technology, discusses their limitations and obstacles, and proposes recommendation guidelines for new technical designs.
A Field Pilot Study on Treating Groundwater Contaminated with Sulfolane Using UV/H2O2
Authors: Yu Linlong , Iranmanesh Sobhan , Keir Ian , Achari Gopal
Published: April 2020

Sulfolane is an emerging contaminant in the groundwater and soil nearby gas plants, which has attracted much attention from many researchers and regulatory agencies in the past ten years. In this paper, a field pilot-scale ultraviolet (UV)/hydrogen peroxide (H2O2) system was investigated for treating sulfolane contaminated groundwater. Different groundwater, as well as different operational parameters such as influent sulfolane concentration, H2O2 dosage, and water flow rates, were studied. The results showed that a pilot-scale UV/H2O2 system can successfully treat sulfolane contaminated groundwater in the field, although the presence of iron and other groundwater limited the process efficiency. The lowest electrical energy per order of reduction for treating sulfolane in groundwater by using the pilot-scale UV/H2O2 system was 1.4 kWh m−3 order−1. The investigated sulfolane initial concentrations and the water flow rates did not impact the sulfolane degradation. The enhancement of sulfolane degradation in an open reservoir by adding ozone was not observed in this study. Furthermore, an operational cost model was formulated to optimize the dosage of H2O2, and a stepwise procedure was developed to determine the power necessary of the UV unit.
An Experimental Assessment of Extreme Wave Evaluation by Integrating Model and Wave Buoy Data

Published: April 2020

Calculating the significant wave height (SWH) in a given location as a function of the return time is an essential tool of coastal and ocean engineering; such a calculation can be carried out by making use of the now widely available weather and wave model chains, which often lead to underestimating the results, or by means of in situ experimental data (mostly, wave buoys), which are only available in a limited number of sites. A procedure is hereby tested whereby the curves of extreme SWH as a function of the return time deriving from model data are integrated with the similar curves computed from buoy data. A considerable improvement in accuracy is gained by making use of this integrated procedure in all locations where buoy data series are not available or are not long enough for a correct estimation. A useful and general design tool has therefore been provided to derive the extreme value SWH for any point in a given area.
Investigation on the Role of Water for the Stability of Shallow Landslides—Insights from Experimental Tests

Published: April 2020

Shallow soil slips are a significant hydrogeological hazard which could affect extended areas of the high-gradient mountainous landscape. Their triggering is highly dependent on the rainfall water infiltration and its further redistribution, as well as the characteristic properties of the soil itself. The complex interaction between those factors generates a considerable degree of uncertainty in the understanding of the governing processes. In this work, we take a small step further towards the untangling of those intricate relationships through observation. The results of a set of 20 downscaled shallow land mass failures are analysed through a principal component analysis and a further detailed look at the resulting parametric trends. Moreover, electrical resistivity tomography measurements are added up to the interpretation of experimental data, by providing a glimpse on the rainfall water infiltration process at the subsurface level. The outcome of this work implies that the coupled interaction between rainfall intensity, hydraulic conductivity and soil moisture gradient is governing the stability of soil and while rainfall intensity and duration are essential instability predictors, they must be integrated with antecedent moisture and site-specific characteristics. A tentative comparison of the dataset with existing rainfall thresholds for shallow landslide occurrence suggests the potential application of experimental tests for thresholds’ definition or validation under the appropriate dimensional analysis. A dimensional analysis indicated the interconnection of parameters intrinsic to the problem, and the significance of scale effects in performing a downscaled simulation of land mass failure.

Published: April 2020

The purpose of this research is to estimate the rockfall and debris flow hazard assessment of the SW escarpment of the Montagna del Morrone (Abruzzo, Central Italy). The study investigated the geomorphology of the escarpment, focusing on the type and distribution of the present landforms. Particular attention was devoted to the slope gravity landforms widely developed in this area, where the effective activity of the gravitational processes is mainly related to the rockfall and debris flows and documented by numerous landslides over time. Working from orography, hydrography, lithology, and geomorphology, the landslide distribution and their potential invasion areas were evaluated through two specific numerical modeling software. RAMMS and Rockyfor3D calculation codes were used in order to analyze the debris flow and rockfall type of landslides, respectively. The obtained results are of great interest when evaluating the hazard assessment in relation to the potential landslides. Moreover, the geographic information systems (GIS) provide a new geomorphological zonation mapping, with the identification of the detachment and certain and/or possible invasion areas of the landslide blocks. This method provides an effective tool to support the correct territorial planning and the management of the infrastructural settlements present in the area and human safety.
Electric Factor—A Comparison of Car Usage Profiles of Electric and Conventional Vehicles by a Probabilistic Approach
Authors: Niklas Ulrich , von Behren Sascha , Chlond Bastian , Vortisch Peter
Published: April 2020

To counteract climate change, electric vehicles are replacing vehicles with internal combustion engine on the automotive market. Therefore, electric vehicles must be accepted and used like conventional vehicles. This study aims to investigate to which extent electric vehicles are already being used like conventional vehicles. To do this, we present a supervised method where we combine usage data from conventional vehicles (from car use model based on survey data) and electric vehicles (from sensor data) in Germany and California. Based on conventional vehicles, eight car usage profiles were defined by hierarchical clustering in a previous study. Using a softmax regression, we estimate for each electric vehicle a probability of assignment for every car usage profile. Comparison of conventional and electric vehicles with a high probability reveals that electric vehicles are used similar for long-distance travel (>100 km) and different for short-distance travel (<10 km) to conventional vehicles. This implies that electric vehicles are indeed used for long-distance travel but are still not entirely used for everyday mobility. This could be because electric vehicles are not yet suitable for all trip purposes (e.g., transport of larger items).

Konvelesan plazma (KP) tedavisi tarihteki salgın hastalık dönemlerinde kullanılmış, etkili olduğu gösterilmiş bir pasif antikor tedavisidir. Konvelesan plazmanın etki mekanizmaları arasında virüsü direkt bağlayarak nötrolize etmek, kompleman aktivasyonu, antikor bağımlı sellüler sitotoksisite ve/veya fagositoz yollarıyla virüs eliminasyonunu başlatmak sayılabilir. Nötralizan antikorlar bu etki mekanizmalarında çok önemlidir. Virüsü inaktive ederek viral replikasyonu engellemesi iyileşmedeki en önemli noktadır. Bu yüzden KP da nötrolizan antikor titresi ölçümü önemlidir. Nötralizan olmayan antikorların viral replikasyonu durdurmadığı in vitro olarak gösterilmiş ve bu antikorların proflakside kullanılabileceği, iyileşmede destekleyici etkileri olduğu öne sürülmüştür. COVİD-19 hastalığında yapılan çalışmalarda da KP nın etkili olduğu görülmüştür.

Uygun donorlerden, fayda görebilecek hastalara nakledilen konvelesan plazma tedavi sonuçları merakla beklenmektedir.
Borehole seismic studies of a volcanic succession from the Lopra-1/1A borehole in the Faroe Islands, northern North Atlantic
Authors: Christie Philip , Gollifer Ian , Cowper David
Published: April 2020

Extruded basalt flows overlying sedimentary sequences present a challenge to hydrocarbon exploration using reflection seismic techniques. The Lopra-1/1A re-entry well on the Faroese island of Suðuroy allowed us to study the seismic characteristics of a thick sequence of basalt flows from well logs and borehole seismic recordings. Data acquired during the deepening operation in 1996 are presented here. The re-entry well found that the seismic event at 2340 m, prognosed from the pre-drill Vertical Seismic Profile (VSP) as a decrease in impedance, was not base basalt and the deepened well remained within the lower series basalts. Nonetheless, compressional and shear sonic logs and a density log were recorded over the full open hole interval. These allowed a firm tie to be made with the reflected wavefield from a new VSP. The sonic logs show a compressional to shear wavespeed ratio of 1.84 which is almost constant with depth. Sonic compressional wavespeeds are 3% higher than seismic velocities, suggesting dispersion in the basalt flows. Azimuthal anisotropy was weakly indicated by the shear sonic log but its orientation is consistent with the directions of mapped master joints in the vicinity of the well. The VSP downgoing compressional wavelet shows good persistence, retaining a dominant period of 28 ms at 3510 m depth. Average vertical velocity is 5248 m/s, higher than previously reported. Attenuation can largely be modelled by geometrical spreading and scattering loss, consistent with other studies. Within the piled flows, the effective Q from scattering is about 35. Elastic layered medium modelling shows some hope that a mode-converted shear wave may be observed at moderate offsets. Like its predecessor, the 1996 VSP indicates a decrease in impedance below the final depth of the well. However, it is unlikely to be basement or sediment and is probably an event within the volcanic sequence.
Palaeomagnetic results from the Lopra-1/1A re-entry well, Faroe Islands
Authors: Abrahamsen Niels
Published: April 2020

The palaeomagnetic dating and evolution of the Faroe Islands are discussed in the context of new density and rock magnetic results from the deepened Lopra-1/1A well. The reversal chronology of the c. 6½ km thick basalt succession is also described. The polarity record of the Faroe Islands may now be correlated in detail with the Geomagnetic Polarity Time Scale. The lowermost (hidden) part of the lower basalt formation correlates with Chron C26r (Selandian age), the top (exposed) part of the lower basalt formation correlates with Chrons C26n, C25r and C25n (Selandian and Thanetian age) and the middle and upper basalt formations correlate with Chron C24n.3r (Ypresian). Inclinations indicate a far-sided position of the palaeomagnetic poles, which is characteristic of results from most Palaeogene volcanics from the northern North Atlantic region. The density, magnetic susceptibility and magnetic remanence of 20 specimens from one solid core (1½ m in length) and 26 sidewall cores from the well between –2219 and –3531 m below sea level (b.s.l.) suggest that the volcanic materials can be divided into two characteristic groups: solid unaltered basalts and altered basalts and tuffs. The magnetic properties are typically log-normally distributed and the carriers of remanence are Ti-poor Ti-magnetites with Curie temperatures close to 580°C. The inclination of the 1½ m core at 2380 m b.s.l. is dominantly negative (two plugs at the very top of the core do show normal polarity, but they are likely to be misoriented as all specimens appear to be from one flow). Magnetic logging (magnetic susceptibility and field intensity) down to 3515 m b.s.l. was made in Lopra-1/1A together with other geophysical logs but did not yield conclusive inclination data.
Thermal structure of the deep Lopra-1/1A borehole in the Faroe Islands

Published: April 2020

Information on temperature, temperature gradients, thermal conductivity and heat flow from the c. 3.5 km deep Lopra-1/1A borehole in the Faroe Islands is presented and analysed. The upper 2450 m of the drilled sequence consists of thick tholeiitic basalt flows and the deeper parts of hyaloclastites and thin beds of basalt. Temperature data originate from high precision temperature logging a long time after drilling to a depth of 2175 m (the original Lopra-1 borehole) and from commercial temperature logs measured a short time after drilling to a depth of 3430 m (Lopra-1/1A). The high-precision temperature log determines accurately levels of inflow of groundwater to the borehole and significant thermal disturbances to a depth of c. 1250 m. Below 1300 m, no significant disturbances are seen and interval temperature gradients for large depth intervals show only small variations between 28 and 33°C/km. The mean least-squares gradient for the depth interval of 1400–3430 m is 31.4°C/ km. In clear contrast to these overall very homogeneous, large-interval, mean temperature gradients, great local variability, between gradients of 20–25°C/km and 45°C/km, was observed between about 1300 and 2175 m (maximum depth of the high-resolution temperature log). These gradient variations are interpreted to be due to thermal conductivity variations and to reflect varying secondary mineralisation and mineral alterations. A preliminary analysis of the Lopra-1/1A temperature–depth function in terms of long-term palaeoclimatic signals indicates subsurface temperatures below about 1300 m to be in equilibrium with mean surface temperatures significantly below zero during the last glacial period. A subsequent temperature increase of 12–16°C occurred at around the termination of the last glaciation. The measured temperatures (some after correction) and the thermal regime below 1300 m seem to represent conductive equilibrium conditions without significant disturbances from the effect of drilling, groundwater flow or long-term palaeoclimatic surface temperature variations. Thermal conductivity measured on samples of basalt taken from drill cores and surface outcrops in the area of the borehole shows values within a rather narrow range and a well-defined mean value for low porosity basalts of about 1.8 W/m°C , while a few samples of lapilli-tuff/tuff from the borehole gave values around 1.9 W/m°C . Lapilli-tuff and tuff seem to have higher matrix (grain) conductivity than basalt. Heat flow is estimated at 60 ± 5 mW/m2. A heat flow of this magnitude is consistent with the Faroe Islands being underlain by continental crust.
Mineralogical and thermodynamic constraints on Palaeogene palaeotemperature conditions during low-grade metamorphism of basaltic lavas recovered from the Lopra-1/1A deep hole, Faroe Islands
Authors: Glassley William E.
Published: April 2020

The sequene of secondary minerals that are reported for the Lopra-1/1A well records progressive zeolite facies to prehnite–pumpellyite-facies mineral progressions consistent with those of other well-studied hydrothermally altered rock sequences. Detailed comparison of the calc–silicate (zeolites and prehnite) mineral distributions of the Lopra-1/1A sequence with those from other regions indicates that this sequence exhibits consistently longer down-hole intervals for secondary mineral species than reported elsewhere. When compared to measured down-hole temperatures reported in other hydrothermally altered regions, the results suggest that the Lopra-1/1A mineral progression formed under conditions typical of low temperature hydrothermal systems that form shortly after eruption of thick basaltic piles. Maximum temperatures achieved at the 3500 m level of the well were at or below 200°C. The implied geothermal gradient was less than 50°C/km. An analysis of prehnite – fluid composition relationships was also conducted in order to determine if results compatible with the paragenetic sequence study could be obtained from thermodynamic constraints. In this case, the limiting temperature for prehnite formation in equilibrium with albite–quartz–calcite–laumontite (the mineral assemblage at the bottom of the hole) was determined for a range of fluid compositions. The resulting calculations suggest temperatures of formation of prehnite in the range of 140°C to 205°C, a conclusion which is broadly consistent with those reached from study of the paragenetic relationships. Comparison of these results with other studies of palaeogeothermal gradients of the North Atlantic margins suggests a consistent pattern in which relatively low geothermal gradients persisted in the Palaeogene rift basin.
A reconnaissance study of fluid inclusions in fracture-filling quartz and calcite from the Lopra-1/1A well, Faroe Islands
Authors: Konnerup-Madsen Jens
Published: April 2020

Fracture-filling calcite and quartz from the Lopra-1/1A well (at 2380 m and 3543 m depth) contains both aqueous low-salinity fluid inclusions and hydrocarbon-dominated fluid inclusions. Microthermometry indicates that the aqueous fluids contain 0.2 to 1.4 equivalent weight% NaCl and occasionally contain traces of hydrocarbons. Homogenisation to liquid occurred between 90°C and 150°C. Modelling based on these fluid inclusion observations indicates that during burial the basaltic section was subjected to temperatures of 160°C and 170°C, occasional pressures of 600–700 bars and the simultaneous percolation of aqueous and hydrocarbon fluids. These fluid conditions may also be relevant to the formation of zeolite observed in the Lopra-1/1A well.

Authors: Chaychenko T. , Kharkova M. , Rybka O.
Published: April 2020

Obesity in adults and children is characterized by epidemiological prevalence with a tendency to increase. Purpose of the study- to analyze the lipid profile in overweight children, depending on the presence of insulin resistance. 247 overweight and obese children aged 2 to 18 were examined, including 160 boys and 87 girls. Obesity was diagnosed if the BMI exceeded 97 percentile, according to gender and age. Assessment of the lipid profile included measurements of total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein. To evaluate the parameters of the lipid profile, we used the National Cholesterol Education Program (NCEP) according to the latest edition (2006). We analyzed lipid values depending on the presence or absence of insulin resistance. BMI was also evaluated according to Z-BMI. Insulin resistance was detected in 69.9% of children. Hyperlipidemia was detected in 24.9% of children and dyslipidemia in 83% of the children examined. A change was found in all indicators of the lipid profile, depending on the presence of insulin resistance. A significant increase in Z-BMI was revealed depending on the presence of insulin resistance. Conclusions: Most overweight children have insulin resistance and dyslipidemia; the type of dyslipidemia in children with obesity directly depends on the presence of insulin resistance.

Waterway sand and pit sand are the most normally utilized fine aggregates for concrete creation in many parts of the world. Huge scale extraction of these materials presents genuine ecological risk in numerous parts of the nation. Aside from the ecological danger, there still exists the issue of intense lack in many regions. In this way, substitute material in place of river sand for concrete production should be considered. The paper means to examine the compressive and split tensile qualities of concrete produced using quarry residue, sand, and a blend of sand and quarry dust. The experimentation is absolutely research facility based. A total of 60 concrete cubes of size 150 mm x 150 mm x 150 mm, and 60 cylinders 150 mm in diameter and 300 mm deep, conforming to M50 grade were casted. All the samples were cured and tested with a steady water/concrete proportion of 0.31. Out of the 60 blocks cast, 20 each were made out of natural river sand, quarry dust and an equivalent blend of sand and quarry dust. It was discovered that the compressive strength and split tensile strength of concrete produced using the blend of quarry residue and sand was higher than the compressive qualities of concrete produced using 100% sand and 100% quarry dust.

Se è sindacale spetta al sindaco o al sindacato?
Authors: D'Achille Paolo
Published: April 2020

Ci sono pervenute varie domande che chiedono se è corretta l’espressione ordinanza sindacale, che si trova spesso negli atti delle amministrazioni comunali per indicare una disposizione emanata dal sindaco, o se non possa generare confusione, visto che l’aggettivo sindacale è normalmente riferito al sindacato (rappresentante sindacale, contributo sindacale, ecc.).
Il prezzo può essere ivato

Qualche dubbio sul cadavere...
Authors: di Valvasone Luisa
Published: April 2020

Diversi lettori ci scrivono in merito alla voce cadavere. Alcuni si domandano quale sia la corretta etimologia della parola e se debba considerarsi un nome comune di cosa o di persona; altri invece ci chiedono se sia opportuno l’uso, prevalentemente giornalistico, di cadavere in funzione aggettivale in espressioni del tipo è stato ritrovato cadavere. Numerosi lettori inoltre segnalano l’impiego del termine riferito al corpo di un animale ritenendolo un uso scorretto e suggerendone la sostituzione con voci più appropriate come carcassa e carogna. Infine, qualcuno ci domanda se salma e cadavere possano considerarsi sinonimi.
Graphene and related 2D materials for desalination : A review of recent patents
Authors: Ramanathan Amall , Aqra Maha
Published: April 2020

The growing population and energy demand, coupled with the depleting
fresh water resources has resulted in great progress in sea water desalination (SWD)
technologies. Nanopores of 2D materials like graphene and its structural
analogs are the latest innovations in membrane technology for SWD. The
performance of these novel atomically thin nanopores as seen from various
experimental and theoretical studies is highly encouraging with reports of
water permeability 2-3 orders of magnitude greater than the conventional reverse
osmosis (RO). The potential
for high efficiency and the low energy requirements of these nanopores for
desalination has led to tremendous efforts in fabrication and
commercialization. We present here a review of the very recent patents
associated with the preparation of these nanopores, the process and the
efficiency of SWD.
Clinico-genetic specifications of Bartter and Gitelman syndrome in children
Authors: Leviashvili J. G. , Savenkova N. D.
Published: April 2020

Molecular genetic research has led to the discovery of new genes encoding proteins – transporters, cotransporters and exchangers involved in the transport of sodium, potassium and chlorine in the thick ascending part of the Henle loop and in the distal convoluted tubule. The article presents modern literature data on the genetic types of tubulopathy with the leading syndrome of hypokalemia and alkalosis – Bartter and Gitelman syndromes in children. The clinical and genetic features of the six types of Bartter syndrome with autosomal recessive and X-linked inheritance, classification approaches, diagnosis, and modern treatment methods are described. Since the first description of Bartter syndrome, 6 clinical genetic options have been known, including antenatal I, II, IVa, IVb, V types, which are potentially life-threatening diseases. Bartter type III syndrome is characterized by the manifestation of hypokalemic alkalosis in children at an early and preschool age. Treatment of Bartter syndrome in children includes the correction of water – electrolyte disturbances, the use of non-steroidal anti-inflammatory drugs (NSAIDs) to inhibit the excessive formation of renal prostaglandin PgE 2. Gitelman syndrome with an autosomal recessive type of inheritance manifests itself in children at school age, later on in adolescents and adults there is an increase in clinical manifestations (with severe hypomagnesemic seizures of the upper and lower extremities, arterial hypertension) requiring correction. The review presents the clinical and genetic features of the rare, atypical form of the autosomal recessive Gitelman syndrome with a manifestation in school age, which is characterized by progressive bilateral calcifications of the subcortical parts of the cerebral hemispheres, calcifications in the basal ganglia and subcortical cerebellum. Unlike Bartter syndrome, with more severe clinical manifestations in newborns, infants and young children, Gitelman syndrome tends to increase clinical manifestations in adolescents and adults. Treatment of Gitelman syndrome in children and adolescents includes the correction of water – electrolyte disturbances, the use of magnesium preparations and salt subsidy.
Reclaiming physician identity: It’s time to integrate ‘Doctor as Person’ into the CanMEDS framework
Authors: Dagnone Jeffery Damon , Glover Takahashi Susan , Whitehead Cynthia , Spadafora Salvatore
Published: April 2020

In 1996, the Royal College of Physicians & Surgeons of Canada (RCPSC) adopted the CanMEDS framework with seven key roles: medical expert, communicator, collaborator, health advocate, manager, professional, and scholar. For many years, CanMEDS has been recognized around the world for defining what patients need from their physicians. From the start, the RCPSC acknowledged that these roles should  evolve over time to continue to meet patient and societal needs (updates in 2005 & 2015).  We propose that  an 8th role is now needed in the framework: “Doctor as Person”. Interestingly, this role was present in the foundational work through the Educating Future Physicians for Ontario (EFPO) project that the RCPSC drew upon in creating CanMEDS more than 20 years ago. Given today’s challenges of providing care in an increasingly stressed Canadian healthcare system, physicians are struggling more than ever with health and wellness, burnout, and the deterioration of the clinical environment. From the patient perspective, there is growing concern that physician-patient interactions are becoming increasingly impersonal and decreasingly patient-centered. The crack emerging in the foundation of physician identity needs to be remedied. We need to pay close attention to how we define ourselves as physicians, by better identifying the competencies required to navigate the personal and professional challenges we face. Only in so doing can we ward off the threat that exists in losing authentic human to human care interactions. Formalizing Doctor as Person as an 8th role in the CanMEDS framework will help patients and physicians create the space to have essential conversations about the humanity of medical care.

Sekolah merupakan tempat formal berlangsungnya proses belajar mengajar. Sekolah memiliki berbagai tingkatan, mulai dari Sekolah Dasar (SD) hingga Sekolah Menengah Kejuruan. Pada tiap tingkatannya, sekolah akan memberikan porsi pembelajaran yang berbeda dan permasalahan yang terjadi pada saat proses pembelajaran cukup beragam. Pada penelitian ini SMK Strada 2 Jakarta memiliki permasalahan dalam proses pembelajaran yang masih menggunakan metode tradisional dan masih sangat terbatasnya penyampaian materi dalam yang diberikan oleh guru, sehingga menurunkan minat siswa untuk belajar. Dalam menghadapi hal tersebut dikembangkanlah E-Learning dengan metode System Development Life Cycle (SDLC) Waterfall sebagai sebuah model pembelajaran yang baru, sehingga peningkatan performa dari guru maupun siswa dapat terjadi, serta informasi yang disampaikan menjadi lebih jelas dan tidak terbatas. Metodologi Waterfall dipilih karena merupakan motode klasik yang sederhana dan sistematik terdiri dari beberapa tahapan yang output tahapan sebelumnya dapat menjadi input tahapan setelahnya. Penelitian ini dimulai dari pengumpulan data melalui wawancara narasumber dan observasi ke lapangan, menganalisis hasil wawancara, desain aplikasi e-learning, coding aplikasi e-learning, testing melakukan uji coba terhadap aplikasi yang telah dibangun, dan maintaining terhadap error ataupun pengembagan kedepannya. Setelah melalui berbagai rangkaian tersebut dihasilkan sebuah aplikasi e-learning berbasis website yang dapat memfasilitasi kebutuhan proses pembelajaran antara guru dan siswa secara online.
