The Theological Importance of Prof. Uwe’s Christian Poems
Authors: Tseng Tseng Kuei-chi Paul
Published: December 2021

Prof. Heinz-Uwe Haus is an internationally renowned director and is considered one of the world’s leading authorities on Bertolt Brecht. Besides his theatrical achievements, he proves to have a profound knowledge of Christian doctrines, which is significantly well portrayed in his Christian poems. His poetic lines unveil the essential spirit of the New Testament. In this paper, a few poems are chosen to illustrate his theological thoughts, which are intricately connected with the core value of the New Testament, including Jesus’ crucifixion, salvation, man’s real nature, fundamental faith, and so on.

Iuliu Maniu and Aurel Constantin Popoviciu were members of the Romanian National Party from Transylvania and Hungary with a different vision on the national assertion of rights and freedom related to the Austro-Hungarian Empire and another ethnic group of Dualist State.
Unexplored implications of the diversity of early belief in Jesus
Authors: Bibliowicz Abel Mordechai
Published: December 2021

The Christian canonical and authoritative texts are the result of complex and layered trajectories and should be understood to reflect - for the most part, debates within the Jesus movement—not struggles with external religious communities. Unexplored implications of the diversity of early belief in Jesus emerge out of deconstructing these debates. Contrary to traditional views and despite a complexity and a variety of contexts, Judaism, Gnosticism, and Paganism were not participants in this struggle. They were the subjects of a debate, (mostly) among Gentile believers, about what belief in Jesus should be.
Theoretical analysis of R22 substitution with R417 on board of fishing vessels - thermodynamic, environmental and Islamic aspects
Authors: Memet Feiza
Published: December 2021

R22 is a refrigerant that has dominated marine refrigeration onboard fishing vessels till 1 January 2015. Because in its composition exist ozone-depleting chlorine atoms, this refrigerant needs acceptable substitution solutions, to achieve the ozone protection desiderate. For R22 was not found a unique replacement solution. This paper investigates the opportunity to substitute R22 with the refrigerant R 417A, due to its very close thermodynamic properties to R22 and, moreover to its friendly behavior to the ozone layer. Seafood consumption is permitted for Muslims, fishing activity being important for these communities. Fishing depends on vapor compression refrigeration technology, equipment known to be an important energy consumer. In this paper, it is shown that environmental preservation is important in the refrigeration industry and in Islam, as well. The theoretical analysis developed in this paper focuses on the seawater cooling system onboard fishing vessels while catching in tropical waters. The investigation has energetic, environmental, and Islamic components. The comparison between the plant working with R22 and with R417A reveals that the ecologic refrigerant represents a wise solution for retrofitting existing plants.

The Crisuri Basin, with its total length of 1093 km (among which 670 km in Romania), is subjected to an effective environmental monitoring system consisting of 18 water stations network. Their integrated information is used for the water assessment problem to understand the biogeochemical processes leading to significant pollution levels in some running water sectors. The goal of this research is to predict the most important factors causing the change of the geochemical measured parameters of some components of the Crisuri water resources. In the present paper, we developed a multivariate statistical model to estimate the spatiotemporal distribution of heavy metals in the field and to identify the contamination sources of Basin River waters. Two methods were deployed as an overall approach to fulfill the proposed objectives, namely the photoneutron activation analysis followed by high-resolution gamma-ray spectrometry and the multivariate statistical analysis. The elements analyzed by different analytical techniques and introduced in databases were As, Cd, Ca, Cu, Fe, Mg, Hg, Na, Ni, Pb, Zn, N-NH4, N-NO2, N-NO3, P-PO4, fixed residues, S-SO4, Cl, phenols and, additional oil compounds. By combining the spatially distributed geochemical data on trace heavy metals with the spatially distributed geophysical data, we obtained the most significant fingerprint factors and their associated uncertainty information concerning the water quality.

Abstract. Delhi is one of the world’s most polluted cities, with very high concentrations of airborne particulate matter. However, little is known on the factors controlling the characteristics of particle number size distributions. Here, new measurements are reported from three field campaigns conducted in winter, pre-monsoon and post-monsoon seasons on the Indian Insitute of Technology campus in the south of the city. Particle number size distributions were measured simultaneously using a Scanning Mobility Particle Sizer and a Grimm optical particle monitor, covering 15 nm to > 10 µm diameter. The merged, wide-range size distributions were categorised into five size ranges: nucleation (15–20 nm), Aitken (20–100 nm), accumulation (100 nm–1 µm), large fine (1–2.5 µm) and coarse (2.5–10 µm) particles. The ultrafine fraction (15–100 nm) accounts for about 52 % of all particles by number (PN10), but just 1 % by PM10 volume (PV10). The measured size distributions are markedly coarser than most from other parts of the world, but are consistent with earlier cascade impactor data from Delhi. Our results suggest substantial aerosol processing by coagulation, condensation and water uptake in the heavily polluted atmosphere, which takes place mostly at nighttime and in the morning hours. Total number concentrations are highest in winter, but the mode of the distribution is largest in the post-monsoon (autumn) season. The accumulation mode particles dominate the particle volume in autumn and winter, while the coarse mode dominates in summer. Polar plots show a huge variation between both size fractions in the same season and between seasons for the same size fraction. The diurnal pattern of particle numbers is strongly reflective of a road traffic influence upon concentrations, especially in autumn and winter. There is a clear influence of diesel traffic at nighttime when it is permitted to enter the city, and also indications in the size distribution data of a mode < 15 nm, probably attributable to CNG/LPG vehicles. New particle formation appears to be infrequent, and in this dataset is limited to one day in the summer campaign. Our results reveal that the very high emissions of airborne particles in Delhi, particularly from traffic, determine the variation of particle number size distributions.

Published: December 2021

Abstract. In ambient air, aqueous-phase oxidation may turn precursors into more light-absorbing and toxic products, leading to air quality deterioration and adverse health effects. In this study, we investigated eugenol degradation in aqueous phase under direct photolysis, and triplet excited organic (3C*) and hydroxyl radical (OH) as oxidants. Results showed degradation rates of eugenol followed the order of 3C* > OH > direct photolysis. Relative contributions of reactive oxygen species (ROS) and 3C* were evaluated via quenching and O2-free experiments. 3C* played a dominant role in eugenol degradation for 3C*-initiated oxidation, while both O2 and O2•-generated were important for eugenol degradation for OH-initiated oxidation. Rate constants under O2, air and N2 followed the order of ko2＞kAir＞kN2 under both direct photolysis and OH oxidation, and it changed to kAir＞kN2＞ko2 in 3C*-initiated oxidation. Light absorption spectra showed absorbance at 300–400 nm increased as photolysis progressed, and there were new broad fluorescent spectra at excitation/emission (Ex/Em) = 250/(400–500) nm, suggesting the formation of new chromophores and fluorophores, such as humic-like substances (HULIS). Additionally, distinct ﬂuorescence peaks appeared at Ex/Em=(300–350)/300 nm at different stages. Concentration of generated HULIS increased gradually over time, then leveled off. Dithiothreitol (DTT) assay was applied to assess the oxidation potential of products, which was greater than pure eugenol, suggesting more harmful species were produced during oxidation. Detailed reaction pathways were elucidated via analyses of chemical characteristics of the products.
Adaptive Thermal Image Velocimetry of spatial wind movement on landscapes using near target infrared cameras
Authors: Schumacher Benjamin , Katurji Marwan , Zhang Jiawei , Zawar-Reza Peyman , Adams Benjamin , Zeeman Matthias
Published: December 2021

Abstract. Thermal Image Velocimetry (TIV) is a near-target remote sensing technique for estimating two- dimensional near-surface wind velocity based on spatiotemporal displacement of fluctuations in surface brightness temperature captured by an infrared camera. The addition of an automated parameterization and the combination of ensemble TIV results into one output made the method more suitable to changing meteorological conditions and less sensitive to noise stemming from the airborne sensor platform. Three field campaigns were carried out to evaluate the algorithm over turf, dry grass and wheat stubble. The derived velocities were validated with independently acquired observations from fine wire thermocouples and sonic anemometers. It was found that the TIV technique correctly derives atmospheric flow patterns close to the ground. Moreover, the modified method resolves wind speed statistics close to the surface at a higher resolution than the traditional measurement methods. Adaptive Thermal Image Velocimetry (A-TIV) is capable of providing contact-less spatial information about near-surface atmospheric motion and can help to be a useful tool in researching turbulent transport processes close to the ground.
A new snow depth data set over northern China by developing a comprehensive framework using the complex GNSS station networks (GSnow-CHINA v1.0, 2013–2020)

Abstract. The currently available long-term snow depth data sets are either from point-scale ground measurements or from gridded satellite/modeled/reanalysis data with coarse spatial resolution, which limits the applications in climate model, hydrological model, and regional snow disaster monitoring. Benefit from its unique advantages of cost-effective and high spatial-temporal resolution (~ 1000 m2, hourly in theory), snow depth retrieval using the Global Navigation Satellite System Interferometric Reflectometry (GNSS-IR) technique has become a popular topic in recent years. However, due to complex environmental and observation conditions, developing robust and operational technology to produce long-term snow depth data sets using observations from various GNSS station networks is still challenging. The two objectives of this study are 1) to propose a comprehensive framework using raw data of the complex GNSS station networks to retrieve snow depth and to control its quality automatically; and 2) to produce a long-term snow depth data set over northern China (i.e., GSnow-CHINA v1.0, 12 h/24 h, 2013–2020) using the proposed framework and historical data from 80 stations. The data set has high internal consistency with regards to different GNSS systems (mean r = 0.97 & RMSD = 1.93 cm), different frequency bands (mean r = 0.96 & RMSD = 2.73 cm), and different GNSS receivers (mean r = 0.88). The data set also has high external consistency with the in-situ measurements and the passive microwave (PMW) product, with a consistent illustration of the interannual snow depth variability. The results also show the good potential of GNSS to derive hourly snow depth observations for better monitoring snow disasters. The proposed framework to develop the data set provides comprehensive and supportive information for users to process raw data of ground GNSS stations with complex environmental conditions and various observation conditions. The resulting GSnow-CHINA v1.0 data set is distinguished from the current point-scale in-situ data or coarse-gridded data, which can be used as an independent data source for validation purposes. The data set is also useful for regional climate research and other meteorological and hydrological applications. The algorithm and the data files will be maintained and updated as more years of data become available in the future. The GSnow-CHINA v1.0 data set is available at https://doi.org/10.11888/Cryos.tpdc.271839 (Wan et al. 2021).

Abstract. Most Land Surface Models (LSMs), the land components of Earth system models (ESMs), include representation of N limitation on ecosystem productivity. However only few of these models have incorporated phosphorus (P) cycling. In tropical ecosystems, this is likely to be particularly important as N tends to be abundant but the availability of rock-derived elements, such as P, can be very low. Thus, without a representation of P cycling, tropical forest response in areas such as Amazonia to rising atmospheric CO2 conditions remains highly uncertain. In this study, we introduced P dynamics and its interactions with the N and carbon (C) cycles into the Joint UK Land Environment Simulator (JULES). The new model (JULES-CNP) includes the representation of P stocks in vegetation and soil pools, as well as key processes controlling fluxes between these pools. We evaluate JULES-CNP at the Amazon nutrient fertilization experiment (AFEX), a low fertility site, representative of about 60 % of Amazon soils. We apply the model under ambient CO2 and elevated CO2. The model is able to reproduce the observed plant and soil P pools and fluxes under ambient CO2. We estimate P to limit net primary productivity (NPP) by 24 % under current CO2 and by 46 % under elevated CO2. Under elevated CO2, biomass in simulations accounting for CNP increase by 10 % relative to at contemporary CO2, although it is 5 % lower compared with CN and C-only simulations. Our results highlight the potential for high P limitation and therefore lower CO2 fertilization capacity in the Amazon forest with low fertility soils.
Spatio-temporal variations of water sources and mixing spots in a riparian zone
Authors: Nogueira Guilherme E. H. , Schmidt Christian , Partington Daniel , Brunner Philip , Fleckenstein Jan H.
Published: December 2021

Abstract. Riparian zones are known to modulate water quality in stream-corridors. They can act as buffers for groundwater borne solutes before they enter the stream at harmful, high concentrations, or facilitate solute turnover and attenuation in zones where stream water (SW) and groundwater (GW) mix. This natural attenuation capacity is strongly controlled by the dynamic exchange of water and solutes between the stream and the adjoining aquifer, creating potential for mixing-dependent reactions to take place. Here, we couple a previously calibrated transient and fully-integrated 3D surface-subsurface, numerical flow model with a Hydraulic Mixing Cell (HMC) method to map the source composition of water along a reach of the 4th-order Selke stream and track its spatio-temporal evolution. This allows us to define zones in the aquifer with similar fractions of surface- and groundwater per aquifer volume (called “mixing hot-spots”), which have a high potential to facilitate mixing-dependent reactions and in turn enhance solute turnover. We further evaluated the HMC results against hydrochemical monitoring data. Our results show that on average about 50 % of the water in the aquifer consists of infiltrating SW. Within about 200 m around the stream the aquifer is almost entirely made up of infiltrated SW with nearly no other water sources mixed in. On average, about 9 % of the aquifer volume could be characterized as “mixing hot-spots”, but this percentage could rise to values nearly 1.5 times higher following large discharge events. Moreover, event intensity (magnitude of peak flow) was found to be more important for the increase of mixing than event duration. Our modelling results further suggest that discharge events more significantly increase mixing potential at greater distances from the stream. In contrast near the stream, the rapid increase of SW influx shifts the ratio between the water fractions to SW, reducing the potential for mixing and the associated reactions. With this easy-to-transfer framework we seek to show the applicability of the HMC method as a complementary approach for the identification of mixing hot-spots in stream corridors, while showing the spatio-temporal controls of the SW-GW mixing process and the implications for riparian biogeochemistry and mixing-dependent turnover processes.
Synoptic processes of winter precipitation in the Upper Indus Basin
Authors: Baudouin Jean-Philippe , Herzog Michael , Petrie Cameron A.
Published: December 2021

Abstract. Precipitation in the Upper Indus Basin is triggered by orographic interaction and the forced uplift of a cross-barrier moisture flow. Winter precipitation events are particularly active in this region and are driven by an approaching upper-troposphere western disturbance. Here statistical tools are used to decompose the winter precipitation time series into a wind and a moisture contribution. The relationship between each contribution and the western disturbances are investigated. We find that the wind contribution is related not only to the intensity of the upper-troposphere disturbances but also to their thermal structure through baroclinic processes. Particularly, a short-lived baroclinic interaction between the western disturbance and the lower-altitude cross-barrier flow occurs due to the shape of the relief. This interaction explains both the high activity of western disturbances in the area and their quick decay as they move further east. We also revealed the existence of a moisture pathway from the Red Sea to the Persian Gulf and the north of the Arabian Sea. A western disturbance strengthens this flow and steers it towards the Upper Indus Plain, particularly if it originates from a more southern latitude. In cases where the disturbance originates from the north-west, its impact on the moisture flow is limited, since the advected continental dry air drastically limits the precipitation output. The study offers a conceptual framework to study the synoptic activity of western disturbances as well as key parameters that explain their precipitation output. This can be used to investigate meso-scale processes or intra-seasonal to inter-annual synoptic activity.

Tinjauan Model Pembelajaran Blended Learning pada Perguruan Tinggi di Era New Normal Covid-19: Kebijakan dan Implementasi
Authors: Zainuddin Zamzami
Published: December 2021

This article aims to review the potential of a Blended learning model implementation in Indonesian higher education institutions during the time of Covid-19. This conceptual paper attempts to explain the concept of Blended learning in terms of theory and practice, based on the literature discussed in several reputable international journals. Blended learning is defined as a learning model integrating face-to-face instruction with an online learning environment or e-learning. Initially, this model proposes to improve the deficiencies of a traditional learning model which is lack of technological resources, and at the same time to develop the gap of e-learning practice which is lack of a face-to-face learning experience. In the blended instruction, students will learn through face-to-face interaction in the classroom and supported by digital media such as a Website, Video, or Learning Management System (LMS). Meanwhile, the use of technologies is ordinarily applied for students' learning and peer-interaction outside of the class, especially for online discussion and homework submission. This method emphasizes that learning activity should not only occur in the classroom but also outside of the class through the digital device.

Possibilitar o aprendizado consciente e prazeroso de todos, é um dos principais anseios dos professores. Aprender matemática para utilizar na vida e fazer com que o aluno reflita, pense e trace estratégias para pensar com autonomia, não é apenas um desejo burocrático de leis e normas que cumprimos, mas sim um pedido de reencontro entre a cultura e o convívio diário. Desse modo, utilizar as raízes culturais para tornar este aprendizado mais próximo do indivíduo, bem como interligado pela Gestalt dos saberes vitais, torna-se importante e valioso para o ser humano. A pesquisa, a ser realizada em três fases, teve sua primeira fase concluída, a qual envolveu saberes etnomatemáticos do Grupo Mucubal de Angola em suas atividades lúdicas. Num segundo momento, ainda em fase de elaboração, tenciona-se verificar em quilombos brasileiros, como se dão tais atividades nas práticas do grupo. E, na última fase, pretende-se elaborar uma obra coletiva, mostrando as atividades lúdicas culturais e saberes matemáticos contemplados pelos grupos participantes da pesquisa nas fases anteriores.

Behavioural problems of children among working and non-working Mothers
Authors: Bisht Mamta
Published: December 2021

For years mothers had been doing a full time job of upbringing their children and addressing their basic needs. However, the present scenario is such that it is not feasible to make a living with just one person’s earnings. Hence, women set out to support their family and the children are taken care of by the secondary caregivers. A number of research studies have revealed that the majority of children suffer from mild to moderate behavioural problems during the early developmental stages. Keeping these changing patterns in mind, the researcher conducted a comparative study at Race Course, Dehradun to assess the behavioural problems of children among working and non-working mothers. The main objectives of the study were to assess the Behavioural problems of children among working and non-working mothers and compare the Behavioural problems of children between working and non-working mothers. Data was collected from 60 working and 60 non-working mothers with the help of non-probability purposive sampling techniques. A structured Child Behaviour Assessment Scale was developed to collect the data from the mothers of children aged 4-12 years. Reliability of the tool was found to be 0.7. The study results revealed that 60% of working mothers reported Borderline Behaviour in their children. Abnormal behaviour consisting of hyperactivity, bad habits and social problems etc. were reported by 15% of working mothers. Children among non-working mothers reported higher levels of anxiety, and conduct problems. Significant association was found between Behavioural problems of children among working mothers and type of family, number of children, age of the child, and gender of the child. Behavioural problems in childhood may lead to limited functional capabilities in children and more serious problems in adulthood. Nurses can play a major role in diminishing Behavioral problems by providing guidance and counselling for the children and their mothers. The focus should be on addressing the emotional needs of the children during the early stages of development.

Aim: The aim of this study was to investigate diurnal variations in admissions to acute psychiatry.

Method: The registration of 2,763 submissions were conducted from 1 April 2015 to 31 December 2017 at the University Hospital of North Norway by completing a form for every admission.

Results: The results revealed that the majority of the admissions took place at evening and night time. There were significantly (p = .001) more admissions at evening and night time. Results revealed that 21.5 % (539) of admissions occurred between 00:00 and 08:00, whereas 27.5 % (758) of admissions occurred between 08:00 and16:00 and 51 % (1,409) of admissions occurred between 16:00 and 00:00.

Conclusion: The causes behind this distribution of admissions should be investigated in future studies and should ask the patients about reasons for the late admissions.

Buenas prácticas y consideraciones genéticas para recuperación de bosques nativos degradados
Authors:   Instituto Forestal (Chile)
Published: December 2021

El presente libro se focaliza en mostrar la línea argumental sobre qué consideraciones genéticas y ecológicas se tuvieron en cuenta para implementar el proyecto 004/2015 “Evaluación de métodos de plantación suplementaria en bosque siempreverde estructuralmente alterado: promoviendo su variabilidad y sustentabilidad”, financiado por el Fondo de Investigación del Bosque Nativo de la Corporación Nacional Forestal. Lo que no es óbice, que dichas consideraciones de carácter universal no se deban aplicar a otras situaciones de restauración ecológica, lo que queda demostrado en los estudios de caso, que más adelante se indican.
Saudi EFL Instructors’ and Students’ Perspectives Towards Virtual Learning During COVID-19 Pandemic
Authors: Alghamdi Ahmed
Published: December 2021

The Covid-19 pandemic and the sudden transition from face-to-face to virtual learning have given rise to various challenges and obstacles in teaching contexts all over the world. This paper explores the impact of this unexpected transition in the teaching and learning process based on English as a foreign language (EFL) teachers’ and learners’ experiences at a Saudi university. This research employed a mixed methods approach. Four male and female EFL teachers were involved in addition to thirty-six students from a preparatory year program. The key findings of the study revealed that there were three major challenges encountered in the use of virtual classroom applications during the pandemic, including crucially a lack of technology and Internet connection, having large numbers of students in a virtual learning classroom, and lack of student and teacher interaction when using virtual learning classes. Although Saudi EFL students and teachers viewed the virtual learning classes in a positive light during the pandemic period, they reported that in the post-pandemic period and over the long term, they would prefer traditional face-to-face teaching.
Impact of COVID-19 on Pennsylvania farm revenue: Looking back at the 2020 season

Published: December 2021

Initial forecasts predicted severe financial losses for small and midsized farmers as the COVID-19 pandemic disrupted usual market channels nationwide. Early reports both confirmed and challenged these fears, as some farmers could not find new markets while others established or expanded their direct-to-consumer sales to replace their lost outlets. To understand the impact of the pandemic on Pennsylvania farmers across the entire 2020 growing season, Chatham University and Pasa Sustainable Agriculture[1] surveyed farmers and performed interviews with a subset of these farmers. The anonymous survey was distributed by Pennsylvania-based farm organizations to their constituents, predominantly through email. Just under half the farmers (42%) reported a loss of revenue, while over half (58%) reported either no change or an increase in revenue in 2020. The scale of these changes varied greatly. We also found that vegetable farmers fared slightly better than livestock/eggs/dairy farmers; those with a higher pre-COVID revenue did better than those with a lower pre-COVID revenue; and farms that were able to increase direct-to-consumer sales maintained or increased their total revenues. Participation in state and federal relief programs varied and appeared to have no significant effect on farmers’ final 2020 revenue. Farmers’ responses to the open-ended survey questions demonstrated that the weather, a lack of infrastructure to support small and midsized producers, and consumers’ lack of support for a regional food system were major challenges before COVID. Without meaningful policy changes, these challenges will persist beyond the pandemic’s resolution.

Published: December 2021

Introduction: Meningoencephalitis caused by the Epstein-Barr virus (EBV) is a rare neurological entity, most often related to the latent reactivation of thevirus associated with immunosuppression. The clinic varies between encephalitis, meningitis, cerebellitis, neuritis and transverse myelitis. The prognosis is good, with 85% of patients returning to baseline levels. Case report: We attend to a 11-month-old male patient, proper neuropsychomotor development, with reports of fever and odynophagia, without improvement with antibiotic therapy. He had a focal epileptic seizure. Upon admission, he presented a new similar event, with control after use of diazepam and intravenous phenobarbital. At the neurological examination carried out after improving the level of consciousness, the patient was alert. He presented axial hypotonia, dystonic posture in flexion of the right upper limb, with preserved strength. He showed no meningeal signs. The cerebrospinal fluid revealed 61 mg/dL of glucose, 57 mg/dL of proteins and 65/mm³ of leukocytes (90% of lymphocytes). Acyclovir, ceftriaxone, and dexamethasone were started, with improvement. Magnetic resonance imaging revealed: FLAIR hyper signal injury, with diffusion restriction, in the left caudate nucleus, left lentiform and ipsilateral anterior midbrain region. Electroencephalogram with diffuse attenuation of baseline electrical activity. The main diagnostic hypothesis was meningoencephalitis secondary to EBV infection, with confirmatory PCR-DNA. Conclusion: The report illustrates the need for attention to a rare infectious etiology in atypical presentation of meningoencephalitis.

Background: There is an increasing demand for neurological consultations. However, geographical and economic barriers and the long waiting lines limit the access. Teleregulation (TR), an asynchronous evaluation made by the neurologist, could optimize the need for presential evaluation. Objectives: The aim of this study was to analyze TR for neurological referral of patients, regarding the information provided, the main reasons for consultation, and the teleneurologist’s final decision. Design and setting: Observational cross-sectional study in Complexo Hospital de Clínicas in Curitiba-PR. Methods: The study selected neurological referrals for evaluation by TR between October 2018 and February 2020. The referrals who had incomplete information were excluded. The main variables analyzed were age, sex, reasons for TR, and final decision by the teleneurologist. Results: Of the 1035 included referrals, 56% were women and the mean age was 50±19.6 years old. The main reasons for TR were therapeutic conduct (32%), diagnosis (31%), and test request (13%) and the main specific clinical reasons were headache (30%), epilepsy (19%), dementia (16%), cerebrovascular diseases (11%), and neuromuscular disorders (10%). More information was requested in 427 (41%) of the consults and no need for in-person consultation occurred in 713 (68%) of cases. Conclusions: The main reasons for TR were management and diagnosis. The study showed that TR can reduce the need for presential assessment by a neurologist in more than two-thirds of cases. However, a great part of the consultations needed additional data. Thus, the optimization of the referrals could further improve this system, reducing its overhead.
