Published: November 2021

Peripheral sensory neurons are the gateway to the environment across species. In Drosophila, olfactory and gustatory senses are required to initiate courtship, as well as for the escalation of courtship patterns that lead to copulation. To be successful, copulation must last long enough to ensure the transfer of sperm and seminal fluid that ultimately leads to fertilization. The fly genitalia contain sex-specific bristle hairs innervated by mechanosensory neurons. To date, the role of the sensory information collected by these peripheral neurons in male copulatory behavior is unknown. Here, we employed genetic manipulations that allow driving gene expression in the male genitalia as a tool to uncover the role of these genitalia specific neurons in copulation. We found that the sensory information received by the mechanosensory neurons (MSNs) at the male genitalia plays a key role in copulation duration. We confirmed that these MSNs are cholinergic and co-express both fru and dsx. Moreover, our results show that the function of these fru/dsx cholinergic MSNs is required for copulation persistence, which ensures copulation is undisrupted in the presence of environmental stress before sperm transfer is complete.
Gravitational cells and gravitational strings as a necessary part of the gravitational field. Obtaining new physical formulas and indicators: the formula for the gravitational constant, the formula for the mass of the hydrogen atom, the formula for the vibrational velocity of a gravitational string, the minimum distance of action of gravitational forces etc.
Authors: Chernov Andrey
Published: November 2021

This study introduces scientific concepts such as gravitational cells and gravitational strings. Gravitational cells and gravitational strings have been organically built into the concept of a gravitational field. This innovation has led to significant scientific results. These results include obtaining the formula for the gravitational constant, the formula for the electron mass, the formula for the mass of the hydrogen atom, the formula for the minimum distance of the action of the gravitational field, etc. All formulas were confirmed by experimental data. In this work, the Planck formula was successfully applied to the gravitational field. A distinctive feature of this study is the fact that most of the new formulas contain only fundamental physical constants (without introducing additional indicators and proportionality coefficients). In this work, the concept of a gravitational quantum is introduced and its value is determined. Also, a new physical constant was obtained - the mass of the gravitational cell of a black hole.
WITHDRAWN: Geogrid Reinforced Brick Buildings for Earthquake Disaster Mitigations
Authors: Behera Biplab , Nanda Radhikesh Prasad
Published: November 2021

In the event of a severe earthquake, the walls of brick buildings experience in-plane shear and out-of-plane bending, leading to diagonal crack and corner failure respectively. In this study, an experimental investigation was carried to observe the above damages on brick masonry buildings reinforced with geogrid embedded in bed joint mortar of the walls. It was observed that the geogrid reinforced brick panels showed better shear strength, lateral strength, ductility, etc. A qualitative comparison was made using a sinusoidal shake table test on a one-fourth single-room building model consisting of two sets of corner walls with and without geogrid reinforcement. It was observed that the corner wall without reinforcement showed crack initiation at 0.45g and complete collapse with over toppling of the transverse wall at 0.90g, while no sign of damages for the corner walls strengthened with geogrid reinforcement for any level of shaking.
Multiple and Complex Codimension-2 Bifurcations underlying Post-inhibitory Rebound Spike and Excitability Transition
Authors: Wang Xianjun , Gu Huaguang , Li Yuye , Lu Bo
Published: November 2021

Neuron exhibits nonlinear dynamics such as excitability transition and post-inhibitory rebound (PIR) spike related to bifurcations, which are associated with information processing, locomotor modulation, or brain disease. PIR spike is evoked by inhibitory stimulation instead of excitatory stimulation, which presents a challenge to the threshold concept. In the present paper, 7 codimension-2 or degenerate bifurcations related to 10 codimension-1 bifurcations are acquired in a neuronal model, which presents the bifurcations underlying the excitability transition and PIR spike. Type I excitability corresponds to saddle-node bifurcation on an invariant cycle (SNIC) bifurcation, and type II excitability to saddle-node (SN) bifurcation or sub-critical Hopf (SubH) bifurcation or sup-critical Hopf (SupH) bifurcation. The excitability transition from type I to II corresponds to the codimension-2 bifurcation, Saddle-Node Homoclinic orbit (SNHO) bifurcation, via which SNIC bifurcation terminates and meanwhile big homoclinic orbit (BHom) bifurcation and SN bifurcation emerge. A degenerate bifurcation via which BHom bifurcation terminates and fold limit cycle (LPC) bifurcation emerges is responsible for spiking transition from type I to II, and the roles of other codimension-2 bifurcations (Cusp, Bogdanov-Takens, and Bautin) are discussed. In addition, different from the widely accepted viewpoint that PIR spike is mainly evoked near Hopf bifurcation rather than SNIC bifurcation, PIR spike is identified to be induced near SNIC or BHom or LPC bifurcations, and threshold curves resemble that of Hopf bifurcation. The complex bifurcations present comprehensive and deep understandings of excitability transition and PIR spike, which are helpful for the modulation to neural firing activities and physiological functions.

Exceptional research activities have been endorsed by the Arabic Sign Language for recognizing gestures and hand signs utilizing the deep learning model. Sign languages refer to the gestures, which are utilized by hearing impaired people for communication. These gestures are complex for understanding by normal people. Due to variation of Arabic Sign Language (ArSL) from one territory to another territory or between countries, the recognition of Arabic Sign Language (ArSL) became an arduous research problem. The recognition of Arabic Sign Language has been learned and implemented utilizing multiple traditional and intelligent approaches and there were only less attempts made for enhancing the process with the help of deep learning networks. The proposed system here encapsulates a Convolutional Neural Network (CNN) based machine learning technique, which utilizes wearable sensors for recognition of the Arabic Sign Language (ArSL). The model suits to all local Arabic gestures, which are used by the hearing-impaired people of the local Arabic community. The proposed system has a reasonable and moderate accuracy. Initially a deep Convolutional network is built for feature extraction, which is extracted from the collected data by the wearable sensors. These sensors are used for recognizing accurately the 30 hand sign letters of the Arabic sign language. DG5-V hand gloves embedded with wearable sensors are used for capturing the hand movements in the dataset. The CNN approach is utilized for the classification purpose. The hand gestures of the Arabic sign language are the input and the vocalized speech is the output of the proposed system. The results achieved a recognition rate of 90%. The proposed system was found highly efficient for translating hand gestures of the Arabic Sign Language into speech and writing.

Background: Noninvasive diagnostic technologies that can dynamically monitor changes in liver inflammation are highly important for the management of chronic hepatitis B (CHB) patients and thus warrant further exploration. This study assessed the diagnostic efficacy of FibroScan for liver inflammation in CHB patients.Methods: A total of 1185 patients were selected, and ultrasound-guided liver biopsy was performed within one month after the FibroScan test. The liver stiffness measurement (LSM), the reliability criteria (IQR/M) of LSM, the quality of liver biopsy (complete portal area, PA), and the liver inflammation grades were the main observation items of this study. With liver biopsy as the control, the diagnostic efficacy of FibroScan for liver inflammation in CHB patients was evaluated by receiver operating characteristic (ROC) curve analysis.Results: Significant differences in the LSM of FibroScan were observed among different grades of liver inflammation (P<0.0001). Liver biopsy (PA>10) served as the control, and the cutoff point and the area under ROC curves (AUCs) of the LSMs for different inflammation grades were as follows: G2, 8.6 kPa, 0.775; G3 9.8 kPa, 0.818; and G4, 11.0 kPa; 0.832. With LSM cutoff values of 8.6 kPa, 9.8 kPa and 11.0 kPa, FibroScan showed certain diagnostic value for CHB patients with G2, G3 and G4 liver inflammation, especially those with G4 inflammation. Conclusions: The results of this study preliminarily showed that, in addition to liver fibrosis, FibroScan could evaluate liver inflammation in CHB patients in a noninvasive manner.

Developing prediction models for emerging infectious diseases from relatively small numbers of cases is a critical need for improving pandemic preparedness. Using COVID-19 as an exemplar, we propose a transfer learning methodology for developing predictive models from multi-modal electronic healthcare records by leveraging information from more prevalent diseases with shared clinical characteristics. Our novel hierarchical, multi-modal model (TransMED) integrates baseline risk factors from the natural language processing of clinical notes at admission, time-series measurements of biomarkers obtained from laboratory tests, and discrete diagnostic, procedure and drug codes. We demonstrate the alignment of TransMED's predictions with well-established clinical knowledge about COVID-19 through univariate and multivariate risk factor driven sub-cohort analysis. TransMED's superior performance over state-of-the-art methods shows that leveraging patient data across modalities and transferring prior knowledge from similar disorders is critical for accurate prediction of patient outcomes, and this approach may serve as an important tool in the early response to future pandemics.

PurposeThe present study aimed to determine the predictive roles of pain, fatigue, nausea, and vomiting in anxiety among the patients undergoing Hematopoietic Stem Cell Transplantation (HSCT).MethodsThe present cross-sectional study was conducted on 200 patients treated by HSCT referred to the centers affiliated to Shiraz University of Medical Sciences, Iran. The data were collected using Spielberger Anxiety Questionnaire, Numerical Pain Scale, Brief Fatigue Inventory, and Rhodes Nausea and Vomiting Index. Then, the data were analyzed using Spearman’s test and multiple regression analysis.ResultsThe means of state anxiety, trait anxiety, pain, fatigue, and nausea, vomiting and retching were 41.67 (SD = 9.71), 43.78 (SD = 9.00), 3.79 (SD = 2.79), 4.23 (SD = 2.48), 6.31 (SD = 7.53), respectively. The results showed that the participants with higher pain and fatigue scores had higher anxiety levels. The individuals who had more nausea and vomiting had higher anxiety levels, as well. It indicated that fatigue, pain, amount of vomiting, and severity of nausea, vomiting and retching were the predictors of trait anxiety. This study showed the predictor role of pain, fatigue, and severity of retching in state anxiety. ConclusionThe study findings revealed an association between anxiety and pain, fatigue, nausea, and vomiting among the HSCT patients. The results also showed that fatigue and pain were the predictors of anxiety among the patients. Yet, future studies are recommended to determine the other factors contributing to anxiety among the HSCT patients.

Published: November 2021

The SPI is the most widely used drought index to provide an acceptable estimation of drought characteristics. The objective of this study was to compare different threshold levels effect on derived drought characteristics, assessment of the spatial variation of meteorological drought properties as well as drought frequency, duration, and value in Kohgilooyeh and Boyer Ahmad Province, Iran, using SPI for 1, 3, 6, 12, 24 and 48 months lead-times, and finally SPI forecasting using Artificial Neural Networks (ANNs). For the first threshold level (scenario), drought properties are extracted based on the standard level of zero, and for the second one, -1 is considered. Results showed that the frequency of drought and wet periods decreased from SPI-1 to 48 for both scenarios in all stations. Max drought duration of stations had an increasing trend from SPI-1 to 48. The average duration of dry periods changed as a function of the time scales; it increased from SPI-1 to 48. Spatial variation of the drought average duration was considerable for long-term drought. Max SPI value did not follow any spatial variation, as it was constant for all lead times in all stations. Average SPI values had a decreasing trend from SPI-1 to 9 but increased from SPI-9 to 48 in all stations. Max average of SPI value observed in short-term drought and min value in medium-term. SPI value general trend was similar in both scenarios, therefore drought threshold level did not affect the results. The third objective was to develop neural network models for drought forecasting. Different architectures are applied to find the best models to forecast SPI over various lead times. The best forecasting results for SPI-3 and 6, obtained from the Quasi-Newton training algorithm, when for SPI-1, 9, 12, 24, and 48, Levenberg-Marquardt was the best. There was an increasing trend in performance measure R2 from SPI-1 to 48 and a decreasing trend in Root Mean Square Error (RMSE). The best input lead-time for SPI-1 to 48 decreased from 11 to 1, the number of hidden layers decreased, but there was no significant trend in hidden neurons. Drought properties could be considered in water resources management to supply water for various demands.

Published: November 2021

Background

Perinatal depression (PD) affects 10-20% of childbearing women. Telehealth is increasingly utilized for mental health services to increase access to care and overcome COVID-19 pandemic barriers. Women’s perspectives on telehealth services for PD is unknown, however. This study's primary objective was to obtain the perspectives of women who participated in an 8-week group videoconference intervention for PD symptoms, including how technology impacted their experience.
Methods

We utilized theoretical sampling and included perinatal women who had completed the 8-week mindfulness-based cognitive-behavioral intervention group. Semi-structured focus groups with four to six women were conducted on a videoconference platform. Primary analysis used grounded theory and a secondary analysis used qualitative description and was conducted by two coding teams. The teams collaborated on the final themes across the analyses.
Results

Three groups, with a total of 17 participants were conducted. Composition consisted of seven postpartum and ten pregnant women from the 47 total participants. Identified core themes regarding their experiences of the videoconference intervention were: positive experiences, negative experiences, suggestions and ideas, and screening and communication.
Conclusion

This study provides growing evidence informed by perinatal women of positive experiences with engagement in a videoconference intervention for PD. Telehealth may be a reasonable and acceptable platform to increase access and retention for mental health services in childbearing women. Further, this pilot work showcases videoconferencing delivery for a wide range of effective and affordable mental health services in low-resource communities.

Die türkisch-russische Geschichte ist eine Geschichte der Rivalitäten. Sie wird wegen 15 Kriege zwischen den beiden Staaten als konflikthaft bezeichnet. Ihren 1. Krieg führten die beiden Staaten wegen Zentralasien, um das Khanat Astrachan (1568–1570). Der Untersuchungszeitraum dieser Dissertation erstreckt sich von diesem Datum bis zum Ende 2019. In diesem Zeitraum rivalisierten die Türkei und Russland geopolitisch in Zentralasien. Diese Arbeit konzentriert sich auf die türkisch-russische Zentralasienpolitik, bzw. darauf, wie die Türkei und Russland auf ihre gegenseitige Zentralasienpolitik reagieren, warum sie in Zentralasien geopolitisch rivalisieren (1. Forschungsfrage) und ob in Zukunft eine türkisch-russische strategische Partnerschaft in Zentralasien möglich ist (2. Forschungsfrage). Politikwissenschaftlich sind diese Fragen von großer Relevanz, weil eine mögliche türkisch-russische strategische Partnerschaft die gesamten Machtverhältnisse der Welt verändern würde.

Published: November 2021

The Teramana goat is an at-risk breed, needing population protection and programs to increase their numbers. The first step for a population increase is the best management of reproduction, leading to an as high as possible number of healthy and viable kids born. To this purpose, beside the optimization of mating, the best possible management of pregnancy and parturition is mandatory. The goat is a prolific farm animal in which single, double, or triple ovulations can occur, leading to singleton, twin or triple pregnancies, and the birth of multiple kids. Twins and triplets are associated to increased risk for perinatal mortality and need a special surveillance and possible assistance at birth. Knowledge of the number of fetuses that have to be delivered from each goat could be a practical tool for a better management of parturition. Among the methods to define the number of fetuses in the goat, the measurement of blood progesterone (P4) concentrations have provided inconsistent results. Therefore, the present study was aimed to assess the possible association between the maternal concentrations of plasma P4 and cortisol (C), two hormones possibly associated to the number of fetuses, measured only once at about two to one week before parturition in Teramana goats, and the number of fetuses. The results, obtained from 23 does, showed that both plasma P4 and C are higher in does bearing multiple fetuses than does with singleton pregnancies. However, the single measurement of plasma C, but not P4, two to one week before the expected parturition in the Teramana goat is useful to distinguish between does bearing singleton and triplet pregnancies for a better surveillance and assistance at delivery. Therefore, it could represent a tool for the best management of reproduction in a breed population at risk for extinction.

Published: November 2021

Groundwater is the main source of water in arid cities where precipitations are low and not evenly distributed. The combined impact of climate variability and intensive human activities has caused a substantial decline in groundwater levels. Understanding the response of groundwater levels to meteorological and anthropogenic factors is a key step to propose water management alternatives. Meteorological and groundwater data were used to design a multi-step approach to assess the influential factors on the groundwater system in the City of Chihuahua, Mexico. The analysis of historical groundwater levels and climate showed a clear increase in meteorological drought, as well as a groundwater abstraction trend since 1986. Rainfall, groundwater recharge, and groundwater level displayed a significant decrease. Overall, the groundwater depth is continuously increasing with a strong correlation with groundwater abstraction. Despite having a significant trend, the changes in land-cover, groundwater recharge, and meteorological drought were not the main factors inducing the decreased level of water in the aquifer. The continuous abstraction of groundwater from 1986 to 2010 has led to a depletion of groundwater levels from 32 to 92 m. The findings of this study lay a foundation for future water resource management in the study area.
What roles do smart sensors play in citizens' water use? From the perspective of household water-saving
Authors: Tian Kang , Chen Zhuo
Published: November 2021

Rapid population growth has led to increasing demand for water resources. Studies have shown that the application of new technologies can effectively influence and promote citizens to save water. The application of smart water sensors can effectively monitor household water consumption and feedback the recorded data to citizens promptly, thereby influencing family members' water-saving attitudes and behaviours. For the widespread use of future water sensors in households, it can demonstrate its essential role in three aspects: water use information feedback to reduce water consumption, water information measurement helps to cultivate water conservation awareness, and water use information release as an effective means of behavioural intervention. This research provides some suggestions for the promotion and use of smart sensors in the home and points out the future research directions for the impact of water sensing on household water-saving behaviour.

Published: November 2021

For the hilly-plain-wetland complex ecosystem in the cold region of Northeast China, in order to solve the problems, which include the scarcity of surface rainfall stations and the inability to provide accurate surface precipitation for hydrological process simulation, based on the observed precipitation of rainfall stations, three remote sensing precipitation products are taken as objects of evaluation. They include TRMM (Tropical Rainfall Measuring Mission) 3B42V7,3B42RT and CHIRPS (Climate Hazards Group InfraRed Precipitation with Station data,CHIP). In this paper, the observation data of rainfall stations and IDWP precipitation data interpolated by IDW (Inverse Distance Weighted) are used as true value of precision comparison, and the detection accuracy of remote sensing precipitation products from 2001 to 2010 is evaluated on the time scale (day, month and quarter) and spatial scale in Naoli River Basin.The results of the study indicated that 3B42V7 and CHIP have a high detection accuracy for precipitation, and their CC (correlation coefficient) values are 0.47 and 0.49 respectively in daily time scale. The accuracy of their observation for monthly precipitation is better than that of daily precipitation, and the CC are 0.85 and 0.87 respectively. The multi-year average precipitation at different grid positions in the basin is overestimated by 3B42RT, and its evaluation results are poor at different time scales. For the precipitation intensity range of (0,20], the observed results of 3B42V7 and rainfall station are close to each other. For the precipitation intensity ranges of (0,1) and (50,+∞), 3B42RT and CHIP have overestimated or underestimated the precipitation in different degrees. Based on the above analysis results, 3B42RT can be considered as data that can detect whether precipitation occurs on different spatial positions in the basin. 3B42V7 and CHIP can be applied to flood forecasting and non-point source pollution control in cold regions.
Effects of three iron material treatments on hydrogen sulfide release from anoxic sediments
Authors: Inoue Tetsunori , Hagino Yuki
Published: November 2021

In eutrophic coastal regions, hydrogen sulfide (H2S) is a harmful material released from sediments under anoxic conditions. To suppress its release, we conducted laboratory experiments and assessed the impacts of treatment with three iron materials (Fe, Fe2O3, and FeOOH), focusing on the area-specific H2S release rate. These materials qualitatively exhibited a substantial suppression of H2S release; however, smaller treatment levels (<150 mmol m−2) were ineffective. FeOOH exhibited the best performance, followed by Fe2O3, and Fe. These differences were likely caused by variations in the oxidation or reduction potential of the materials and their reaction rates with H2S. A simplified model suggested that the required minimum Fe2+ concentration was determined using the H2S diffusivity, reaction rate constant, and treatment penetration depth. As the former two are physical constants, the latter must control the H2S release rate. Iron materials were experimentally confirmed to persist for over three weeks, and the effective treatment level was theoretically estimated as being capable of suppressing H2S release for more than a year. Our results will contribute to coastal environmental management and particularly benefit port authorities who manage enclosed and eutrophicated harbors and navigation channels where slag application should be avoided.

El objetivo de este trabajo es describir las condiciones ambientales y productivas de 20 unidades domésticas dedicadas a la cría de cabras en el semidesierto potosino. Partiendo de entrevistas y observación etnográfica, se analizan las relaciones entre familias, ejido, ganado, entorno natural y mercado. Se recalca la importancia de las cabras en las zonas áridas, dado que solo posibilitan la subsistencia precaria de los caprinocultores y sus familias. Paradójicamente, se demuestra que la caprinocultura no es redituable debido a las adversas condiciones históricas, socioeconómicas y ambientales. Se enfatiza la importancia del ambiente como elemento imprescindible para los procesos productivos y la reproducción social del campesinado. Se evidencia la estrecha interrelación entre las condiciones de pobreza y la degradación ambiental como resultado de la dominación del capitalismo.
Eosinophilic Gastrointestinal Diseases in Children: A Practical Review
Authors: Licari Amelia , Votto Martina , D’Auria Enza , Castagnoli Riccardo , Caimmi Silvia Maria Elena , Marseglia Gian Luigi
Published: November 2021

Primary eosinophilic gastrointestinal diseases (EGIDs) represent a heterogeneous group
of disorders characterized by eosinophilic inflammation in the absence of known causes for eosinophilia,
selectively affecting different segments of the gastrointestinal tract. While pediatric eosinophilic
esophagitis (EoE) is a well-defined disease with established guidelines, Eosinophilic Gastritis
(EoG), Eosinophilic Gastroenteritis (EoGE) and Eosinophilic Colitis (EoC) remain a clinical
enigma with evidence based on limited anecdotal case reports. Large cross-sectional studies in the
US defined a prevalence of EoG and EoGE ranging from 1,5 to 6,4/100.000 and from 2,7 to
8,3/100.000 subjects respectively, while the prevalence of EoC ranges from 1,7 to 3,5/100.000 subjects.
Regarding the pathogenesis, it is hypothesized that EGIDs result from the interplay between
genetic predisposition, intestinal dysbiosis and environmental triggers. Clinically, EGIDs might
present with different and nonspecific gastrointestinal symptoms depending on the involved intestinal
tract and the extension of eosinophilic inflammatory infiltrate. The diagnosis of EGIDs requires:
1. recurrent gastrointestinal symptoms, 2. increased eosinophils for high power field in biopsy
specimens, 3. absence of secondary causes of gastrointestinal eosinophilia. No validated
guidelines are available on the clinical management of patients with EGIDs. Evidence from case
reports and small uncontrolled case series suggests the use of dietary and corticosteroids as the
first-line treatments. Considering the clinical follow-up of EGIDs, three different patterns of disease
course are identified: single flare, recurring course-disease and chronic course-disease. This
review will focus on pediatric EGIDs distal to esophagus, including Eosinophilic Gastritis (EoG),
Eosinophilic Gastroenteritis (EoGE) and Eosinophilic Colitis (EoC).
Human Microbiome and Allergic Diseases in Children: Pathogenetic Role and Therapeutic Options
Authors: Musso Paola , Chiappini Elena , Bernardini Roberto
Published: November 2021

The recent and extensive study of the microbiome has provided an enormous amount of
data concerning the type and possible functions of microorganisms present in the gut, airways, genital
tract, and skin. These data showed interpersonal differences in the composition of the microbiome
and these differences suggest a link between the microbiome, the immune modulation, and the
pathogenesis of allergic diseases.

This research is particularly relevant in paediatrics, since allergic diseases are constantly increasing
and there is evidence in the paediatric age that shows that the composition of the microbiome in the
foetal and neonatal period plays a key role in the development of the immune system: vaginal delivery,
breastfeeding, childhood spent in rural environments and/or in contact with animals result in
a greater biodiversity of the microbiome with the presence of protective species that reduce the activation
of Th2 lymphocytes, involved in allergic reactions.

Further studies are necessary to better understand the microbiota role in the pathogenesis of atopy
in order to understand if specific probiotics and prebiotics, administered orally or topically, can affect
the microbiota composition and modulate immune system functions, producing a therapeutic
effect in the treatment of allergic diseases.

This narrative review analysed the available literature regarding the correlation between the microbiome
and the development of allergic diseases and with special focus on paediatric studies. The
skin, gut or lung dysbiosis can be a cofactor in the pathogenesis of allergies and the remodulation
of the microbiome becomes an important therapeutic challenge.

Peculiarities of teaching a foreign language to lawyers students
Authors: Starostina Oksana , Horytska Olena
Published: November 2021

The language of law is a technical language, different from other technical languages such as mathematics or physics, as it is bound to the national legal system and has its own highly specialised terminology. In a language of special communication, the text is expressed in a special language or sub-language that is subject to specific syntactic, semantic and pragmatic rules. Purpose of the study: To examine the specific features of teaching a foreign language to lawyers students. A systematic review can be explained as a research method and process for identifying and critically evaluating relevant studies and for collecting and analysing data from those studies. An excellent result of teaching legal English involves providing students with the ability to formulate speech with specific terminology and to develop their thinking about the law. Here's why teachers encourage discussion and role-playing to improve students' oral expression. An excellent method of developing listening skills in the absence of native speakers is video. We use this method with our class and it has proved very effective in attaining communication purposes. Teachers design all kinds of exercises for students and apply them while watching or post-viewing videos.

Abstract: This study is aimed to investigate the Strategic Map of the Incubator center. The business incubation process can vary from one incubator to another. This research extends the previous works to improve the solution business incubator problems in Indonesia heading their competitive advantages heading to the global market compared to the Taiwan cases. This study investigates the different types of business incubator strategies for Indonesia and Taiwan cases by using quantitative and qualitative with the primary that had been collected through surveys and observations. The Result shows that Chaoyang Business Incubation Center (CBIC) and Business Incubator LPPM UNY have quite different patterns of their strategies. The Business Support Model Represent CBIC is program demand: Entrepreneur-initiated, whereas LPPM one is program supply: Incubator-initiated. The Business Incubator LPPM UNY is likely to be more active than BCIC. However, CBIC seems to promote entrepreneurs more actively rather than Business Incubator LPPM UNY.Keywords: Strategic Map, Incubation Center, Indonesia, Taiwan Peta Strategis Pusat Inkubasi Universitas Abstrak: Penelitian ini bertujuan untuk menyelidiki peta strategis dari pusat inkubator.

Method to define the characteristic phases in the behavior of unidirectionally coupled systems being near the boundary of the generalized chaotic synchronization regime onset, based on calculation of the probability of the synchronous regime observation in ensemble of coupled systems is proposed. Using the example of unidirectionally coupled Rössler systems in the band chaos regime we show its efficiency in comparison with the other known methods for detection the characteristics of intermittent generalized synchronization.

Composites based on n-alkane and nanoscale additives were investigated to determine the efficiency of heat transfer during phase transitions in phase change materials. It was found that the thermal conductivity of composite materials is several times higher than the thermal conductivity of the initial n-alkane. The observed effect is due to the specificity of the supramolecular nanostructure of the composite, which differs from the supramolecular structure of the nonadecane.

Since to the stability of the functional properties of a transparent conducting three-layer structure ZnO:Ga/Ag/ZnO:Ga is important for practical application, we studied its long-term durability and thermal stability in air environment. It has been demonstrated that after prolonged interaction with the air environment at room temperature (~ 1000 h) and further heat treatment in air at temperatures up to 450 ° C (up to 10 h), the three-layer structure retains its integrity and is characterized by a low sheet resistance Rs = 2.8 Ω/sq at average transmittance in the visible range Tav of 82.1%.

La naranja agria (Citrus aurantium L.) presenta un alto valor nutricional y gastronómico en el distrito de Huacho, Lima, Perú, pero en la actualidad se considera una especie en peligro de desaparecer del distrito y alrededores por problemas fitosanitarios. Para la recuperación y repoblación de esta especie se planteó emplear técnicas biotecnológicas para la obtención de plantas libres de patógenos. Por lo tanto, el objetivo de la presente investigación fue micropropagar in vitro naranja agria a partir de segmentos nodales. Los segmentos nodales de naranja agria fueron desinfectados en diferentes concentraciones de NaClO, luego se introdijeron en medio de cultivo MS (Murashige y Skoog) adicionado con BAP, KIN y AG3 para la fase de multiplicación, posteriormente se transfirieron a medios MS adicionado con IBA y ANA para la fase de enraizamiento. La evaluación del porcentaje de contaminación se realizó a los diez días, la evaluación de formación de brotes en fase de multiplicación se realizó a los 30 días y la evaluación de enraizamiento a los 30 días. En la fase de desinfección y establecimiento in vitro se logró obtener 0% de contaminación y 0% de oxidación de los explantes. En la fase de multiplicación in vitro los mejores resultados se obtuvieron en el medio de cultivo M8 generando 4,7 brotes por explante. Y finalmente en la fase de enraizamiento el medio E4 permitió obtener 94,7% de explantes enraizados, 23,4 mm de longitud de raíz y 2,2 raíces por explante.
