Review of geothermal conditions of Hungary
Authors: Lenkey Laszlo , Mihályka János , Paróczi Petra 
Published: April 2021

The heat flow map of Hungary was presented in the Atlas of Geothermal Resources in Europe in 2002 and was last updated in 2005. Since that time several geothermal projects, e.g. TransEnergy (2010-13), assessment of the geothermal potential of the Drava basin (2013) Paks-II, NPP (2016) and continuous drilling activity in the country have been in progress. Large amount of temperature data became available, which allowed the update of the Geothermal Database of Hungary and the compilation of an updated heat flow map and temperature maps.
The heat flow is determined based on the Fourier law using the thermal conductivities of rocks and temperature gradient calculated from temperature observations in boreholes and wells. The thermal conductivity is known from laboratory measurements made on core samples. The thermal conductivities and the temperature data are stored in the Geothermal Database of Hungary.
The heat flow is calculated in 2001 boreholes and wells using the Bullard-plot technique. The mean heat flow in Hungary is 90 mW/m2, varying between 30 mW/m2 and 120 mW/m2. The high values are found over buried basement highs in the eastern and southern part of the country, while the low values are located in the recharge areas of karstic flow systems. In the sedimentary basins, where the thickness of the Neogene and Quaternary sediments reaches 5-7 km, the heat flow is slightly below the mean value (80-90 mW/m2) due to the cooling effect of sedimentation. These basins contain the main thermal water aquifer in Hungary utilized for district heating and green house heating. The buried basement highs characterized by high heat flow (100-120 mW/m2) are potential sites to create artificial geothermal reservoirs by hydraulic fracturing (EGS).
Temperature maps at 500 m, 1 km, 2 km and 3 km depths were also compiled. Similarly to the heat flow, the temperature anomalies strongly reflect the local and regional groundwater flow systems.

AIM OF STUDY To compare the effectiveness of surgical treatment of patients with hypertensive intracerebral hematomas (ICHs) of subcortical location and methods of endoscopic aspiration and open removal.MATERIAl AND METHODS The results of surgical treatment of 97 patients with hypertensive subcortical hematomas were analyzed. In group 1 (n=52),endoscopic aspiration of the ICH was performed using a frameless navigation station, in group 2 (n=45), open removal of the ICH was performed using a microsurgical method.RESUlTS Mortality among patients in the age group over 71 years after endoscopic aspiration of ICH was significantly lower than after open removal (30.8% and 60%, respectively). With a decrease in the level of wakefulness to sopor, the mortality rate with endoscopic removal was 50%, and with open intervention — 66.7%, with a decrease to coma — 100% in both groups. Among patients of the 1st group with the volume of ICH less than 40 cm3, the lethality was 11.1%, while in the 2nd group this indicator was almost 2 times higher — 20%. With endoscopic removal of an intrauterine device with a volume of 40 to 60 cm3, the mortality rate reached 14.3%, and with an open removal of a hematoma of the same volume, this indicator reached 30%, while the mortality rate in both groups was similar with a volume of an intrauterine device from 61 to 100 cm3 and amounted to 23.1% and 21.4% in the 1st and 2nd groups, respectively. The radicality of hematoma removal in the 1st and 2nd groups was 86.4% and 86%, respectively.CONClUSION Endoscopic removal of hypertensive subcortical hematomas revealed a greater number of patients with good recovery, and postoperative mortality was 11.3% lower than with open removal, which, along with the simplicity of execution and minimally invasiveness, indicates the safety and efficiency of endoscopic aspiration for surgical treatment of patients with intracerebral hematomas of subcortical location.

Published: April 2021

The pathology of the appendix remains one of the topical areas of abdominal surgery. Its rare diseases can be difficult to diagnose and treat, and are accompanied by the development of serious complications. One of them is intussusception of the appendix to the cecum. Intussusception can be caused by previously undiagnosed primary lesions of the appendix. At the same time, it can simulate tumor and tumor-like formations of the cecum and lead to diagnostic errors. The literature review provides modern data on the history of the study of the problem, the epidemiology of classification, the causes and mechanisms of the development of appendiceal intussusception, the methods of its diagnosis and treatment.

The increase in the number of patients with complications of cardiovascular diseases and the need for early diagnosis of such complications and the early initiation of treatment already at the prehospital stage leads to an increasing need for more frequent use of helicopter medical equipment, as well as for equipping aviation medical teams with highly qualified specialists. The formation of a network of vascular invasive centers in the Moscow region, modern equipment and its use in air ambulance conditions require constant improvement of skills among medical workers. All this undoubtedly leads to positive results, the mortality rate from heart attacks and strokes decreases, the duration of treatment and the period of rehabilitation of patients are reduced. It should be noted that even 10 years ago, medical helicopters were used in the elimination of medical consequences in road accidents, fires and emergencies. Today, aviation medical teams are involved in more than 50% of cases with cardiovascular diseases, which undoubtedly speaks of the prospects for the development of medical aviation in large cities.

Today, the problem of spleen injury in children still appears relevant. The choice of diagnostics and treatment tactics at the present stage is far from being unified. The priority direction is the organ-preserving approach, which is possible and justified in children, which significantly reduces surgical aggression and prevents the likelihood of negative consequences of splenectomy. The choice of the optimal diagnostic method and determination of safe treatment tactics was the purpose of our study. Thirty-nine injured children were treated in 2007–2019. The predominant cause of spleen injury was fall from height (64.1%). Echography was the main diagnostic method, which was performed around the clock. Splenectomy was performed in 7 patients (17.9%), in 32 children (82.1%) the organ was preserved. One case (2.6%) was fatal. The analysis of our own results showed that the widespread use of echography, particularly by surgeons, is necessary in the emergency service and greatly simplifies the work. The developed local protocol for diagnosis and treatment is simple and accessible, since it is based on the interpretation of the main criteria, such as systemic hemodynamics and hemoperitoneum. Continued bleeding reasons diagnostic laparoscopy. With unstable hemodynamics, large hemoperitoneum, laparotomy is indicated.

BACKGROUND Fractures of the proximal humerus are more common in older adults. Two options for surgical treatment of the same fractures are routinely performed — primary arthroplasty and osteosynthesis with metal fixators. Both methods are most effective in elderly patients for augmentation of the proximal humerus. For this purpose, methyl methacrylate cement or bone allo-/autografts are used. However, the incidence of unsatisfactory functional results after surgery remains high.AIM OF STUDY To develop allogeneic graft to strengthen the proximal humerus in the osteosynthesis of a comminuted fracture with a lack of bone tissue which has osteoconductive properties and capable of being a carrier of biologically active substances.MATERIAl AND METHODS The head, neck and portion of diaphysis of a fibula of a cadaver were used for a graft. The graft 6–8 cm long was formed and saturated with a collagen solution. Ten patients with 4-fragment fractures of the proximal humerus underwent surgery. X-rays and computed tomography of the operated joint were performed the day after surgery, and then, 6 weeks, 6 months, and one year after the surgery. The follow-up period ranged from 6 to 18 months.RESUlTS When evaluating osteoconductive effect in cell culture during saturation with collagen, the content cells on the surface of bone was 5–8 thousand/cm2 and 16–18 thousand/cm2 on the sample, saturated with plasma and growth factors. The studied bone grafts were biocompatible and non-toxic for fibroblast culture. On the surface of the bone graft without collagen adhesion of minimum number of cells occurred. After saturation of the graft with collagen, the adhesive activity of cells on the bone matrix increased, which indicated the presence of an osteoconductive effect. The addition of plasma saturated with growth factors promoted an increase in the number of adhered cells; therefore, the graft can be used as a carrier of biologically active substances. Postoperative X-ray didn’t reveal secondary varus displacement of the head in any patient (except for ununiformed fracture case).CONClUSION The developed graft is non-toxic, does not possess immunogenicity, has more pronounced osteoconductive properties in comparison with native bone allografts, which contributes to its colonization with cells. The use of such a graft in clinical practice makes it possible to achieve healing of the fracture and prevent secondary displacement of fragments.

El lenguaje escrito es, posiblemente, la forma de comunicación que más hacontribuido al progreso humano, tanto en ciencia y técnica como en arte, sobre todo en literatura. Ciertamente, el lenguaje escrito constituye un signo de un signo, es decir, una representación del lenguaje oral. Pero, al mismo tiempo, es algo más. De hecho, cuando escribimos nos vemos impelidos a pensar mejor, a aclarar nuestras ideas, a cuidar la forma de expresión. Al hablar improvisamos, codificamos nuestros mensajes de manera automática y automáticamente descodificamos las palabras de nuestro interlocutor. No existe tal automatismo al enfrentarnos a la lengua escrita. Dominar una lengua es dominar tanto la lengua oral como la lengua escrita.Hoy por hoy, uno de las mayores deficiencias a las que se enfrenta la escuela, en todos sus niveles, desde la Educación Primaria hasta la Universidad, es la lectura. Salvando los diferentes niveles, raramente se alcanza un grado adecuado de lectura eficaz (rapidez lectora y comprensión de lo leído).En la preocupación por contribuir al logro de la Lectura y Escritura eficaces, surge el programa de ordenador llamado ProLecturas.
Mediación lingüística del texto literario en la enseñanza del español L2: un estudio sobre las variables de facilitación de la lectura y su legibilidad
Authors: Ocampo González Aldo 
Published: April 2021

Este estudio analiza los procesos de mediación lingüística del texto literario en la enseñanza del español como lengua extranjera. Específicamente, se profundiza en las variables de legibilidad incidentes en la facilitación del discurso escrito a colectivos de estudiantes provenientes de Haití, quiénes reciben clases de español en la ciudad de Santiago de Chile y, demuestran dificultades significativas de acceso a la lectura y a su comprensión. Se opta por un estudio cuantitativo de tipo descriptivo, con un diseño no-experimental de tipo trasversal. Se recurrió a la estadística descriptiva para el procesamiento de los datos recogidos mediante la aplicación de una escala likert dirigida a docentes y estudiantes de español. El primer instrumento describe las estrategias de mediación lingüística utilizadas por el profesorado, mientras que el segundo, efectúa una evaluación de las estrategias de lecturas, gustos y preferencias del estudiantado. Se concluye sobre la identificación de las dimensiones epistémicas que sustentan el discurso de la legibilidad y la lecturabilidad en el campo de la didáctica de segundas lenguas, desconociendo su potencial didáctico y su escaso nivel de implicación en actividades propias del trabajo pedagógico.

El artículo trata de mostrar de forma general los principales problemas de comprensión lectora con que nos encontramos en los centros escolares. Enconcreto en el centro de Educación Secundaria IES Américo Castro, son bastantes frecuentes este tipo de problemas, que el alumnado no comprende lo que lee le repercute de forma negativa en la realización de todo tipo de actividades (exámenes, tareas, etc.) y en todas las áreas o materias. Es por eso que el artículo resume las principales actuaciones que se llevan a cabo en el centro, sobre todo a través del Plan de Lectura, para intentar paliar este tipo de dificultades. La mayoría de estas propuestas están basadas en tres ejes: una metodología dinámica, lúdica y motivadora para el alumnado; la colaboración de todos los profesores/as y todos los departamentos y, sobre todo, partir de los intereses y las motivaciones de nuestro alumnado para fomentar el hábito lector como base de la competencia lectora.
Examination of sexual dimorphism in New-Zealand White × Californian rabbits by morphological traits
Authors: Rotimi Emmanuel Abayomi 
Published: April 2021

Abstract
Rabbits provide a cheap source of high quality animal protein and thus have the potential to bridge the shortage of animal protein in developing countries. Data were collected on 174 New Zealand × California cross-bred rabbits (87 males and 87 females) for this study, to quantify the morphological characteristics and to determine the morphological parameters that contribute to body conformation using Principal Component Analysis (PCA). Data were collected on live body weight (LBW), body length (BDL), ear length (EAL), tail length (TAL), rump length (RUL), heart girth (HAG) and abdominal circumference (ADC). Data collected were analysed using the procedures of the PAST® 3.21 statistical package. Mean live body weight (± SE) for the females (0.980 ± 0.02 kg) and males (0.790 ± 0.02 kg) was recorded. There were positive and highly significant (p < 0.01) correlation coefficients between live body weight and the linear body measurements. One principal component was extracted, accounting for 64.8% of the total variances in morphological indicators measured in the New Zealand × California rabbits. The extracted principal component in this study could be used as aid in selection programme. The results obtained revealed the occurrence of sexual dimorphism, where female rabbits recorded significantly (p < 0.05) higher values than males in all the traits measured. This information suggests that use of rabbit for meat production should skew towards raising female rabbits.
