Root distributions predict shrub-steppe responses to precipitation intensity
Authors: Kulmatiski Andrew , Holdrege Martin C. , Chirvasa Cristina , Beard Karen H.
Published: February 2023

Abstract. Precipitation events are becoming more intense around the world, changing the way water moves through soils and plants. Plants that have, or create, roots that absorb more water under these conditions are likely to become more abundant (e.g., shrub encroachment). Yet, it remains difficult to predict species responses to climate change because we typically do not know where active roots are located or how much water they absorb. Here, we used water tracer injections in a field experiment to describe forb, grass, and shrub root distributions under low and high precipitation intensity treatments. To estimate how much water different active rooting distributions can absorb over time, we used a soil water flow model, and we compared our estimates of water uptake to aboveground plant growth. In low precipitation intensity plots, deep shrub roots were estimated to absorb the most water (93 mm yr−1) and shrubs had the greatest aboveground cover (27 %). Grass root distributions were estimated to absorb an intermediate amount of water (80 mm yr−1) and grasses had intermediate aboveground cover (18 %). Forb root distributions were estimated to absorb the least water (79 mm yr−1) and had the least aboveground cover (12 % cover). In high precipitation intensity plots, shrub and forb roots moved in ways that increased their water uptake relative to grasses, predicting the increased aboveground growth of shrubs and forbs in these plots. In short, water uptake caused by different rooting distributions predicted plant aboveground cover. Our results suggest that detailed descriptions of active plant root distributions can predict plant growth responses to climate change in arid and semi-arid ecosystems.

Published: February 2023

Abstract. On timescales longer than the solar cycle, long-term changes in CO2 concentration and geomagnetic field have the potential to affect thermospheric dynamics. In this paper, we investigate the thermospheric dynamical response to these two factors during the Holocene, using two sets of ~12,000-yr control runs by the coupled thermosphere-ionosphere model, GCITEM-IGGCAS. The main results indicate that increased/decreased CO2 will enhance/weaken the thermospheric circulation throughout the Holocene, but this effect is nonlinear. The cooling effect of CO2 in the thermosphere further provides plausible conditions for atmospheric tidal propagation and increases the thermospheric tidal amplitude. Geomagnetic variations induce hemispheric asymmetrical responses in the thermospheric circulation. Large changes in the circulation occur at high latitudes in the hemisphere with distant magnetic poles drift, inferring a crucial role of geomagnetic non-dipole variations in circulation changes. A positive correlation between the diurnal migrating tide (DW1) and geomagnetic dipole moment is revealed for the first time. The amplitude of DW1 in temperature will increase by ~1–3 K for each 1×1022 Am2 increase in dipole moment.
A range of outcomes: the combined effects of internal variability and anthropogenic forcing on regional climate trends over Europe
Authors: Deser Clara , Phillips Adam S.
Published: February 2023

Abstract. Disentangling the effects of internal variability and anthropogenic forcing on regional climate trends remains a key challenge with far-reaching implications. Due to its largely unpredictable nature on timescales longer than a decade, internal climate variability limits the accuracy of climate model projections, introduces challenges in attributing past climate changes, and complicates climate model evaluation. Here, we highlight recent advances in climate modeling and physical understanding that have led to novel insights about these key issues. In particular, we synthesize new findings from large-ensemble simulations with Earth system models, observational large ensembles, and dynamical adjustment methodologies, with a focus on European climate.

Published: February 2023

Alongside active surveillance at ports and land transport sites, the UK Health Security Agency runs a passive mosquito surveillance scheme: The Mosquito Recording Scheme (MRS). The MRS is a citizen-science scheme, it receives and identifies mosquitoes submitted by members of the public, including in response to nuisance biting incidents. The aims of the scheme are to detect unusual or invasive species, provide a log of reportable incidents of nuisance mosquito biting, and gain insight into the seasonality of British mosquito biting. Between 2005 and 2021, 286 submissions of mosquitoes were submitted to the MRS, all of which were native UK species, 23 specifically reported nuisance biting, with 92.7% of submissions from England. In total 16 species were submitted with Culiseta annulata (39%) and Culex pipiens s.l. (26% of submissions) the most common, with records of these species throughout the years. Case studies giving examples of a range of submissions and a flow chart of the workflow when receiving a submission are described. Reasons for the low incidence of submissions compared to comparable schemes in Europe are discussed and recommendations on how to improve the scheme is given.

Characterization of spherical and plane curves using rotation minimizing frames
Authors: Da Silva Luiz C. B.
Published: February 2023

In this work, we study plane and spherical curves in Euclidean and Lorentz-Minkowski 3-spaces by employing rotation minimizing (RM) frames. By conveniently writing the curvature and torsion for a curve on a sphere, we show how to find the angle between the principal normal and an RM vector field for spherical curves. Later, we characterize plane and spherical curves as curves whose position vector lies, up to a translation, on a moving plane spanned by their unit tangent and an RM vector field. Finally, as an application, we characterize Bertrand curves as curves whose so-called natural mates are spherical.

未來戰場環境將是高度變動、不確定性、複雜及混沌不明的複合環境，領導幹部往往須採取分權式任務式指揮哲學與作法，才有可能在戰場上奪取主動權、掌握契機，俾利戰勝未來之敵。

單位文化中往往存在微觀管理與風險規避的文化，肇因在於上級對下級的不信任、要求零缺陷標準，以及不願承擔失敗後果；試想若風險承擔者都會遭受懲罰，那單位最後也只會剩下風險規避者與微觀管理者而已，這將是單位的大不幸。

任務式指揮成功之道在於指揮鏈上下具有共同理解與共同認知，理解指揮官意圖只提供大方向，基層指揮幹部應及時下達正確決策，不能坐等層層同意的程序，因為這種方式將無法在未來戰場存活；鑒此，國軍當前或未來重點工作應將任務式指揮納入課題並加以實踐。

Published: February 2023

Contaminated food and drinks are source of various food borne diseases in human.  The study aimed on the assessment of bacterial load of locally prepared fruit juice. A cross sectional study was conducted from January 2015 to May 2015in Hossana town. Out of Twenty four fruit juice samples, eight samples from each of avocado, papaya and mango were collected at two different time intervals accordingly. The pH of original samples was determined before dilution. Streak plate method was used for the growth of bacteria on appropriate media. Structured questionnaire was prepared to assess storage mechanism of fruit, source of fruit, processing and hygienic condition of working environment.  Concerning pH there was slight increase in juices that were collected at night. The probable reason may be inappropriate storage of fruit and over dilution of fruit juices. Regarding the bacterial load of fruit juice samples both avocado9 (38.38%) and papaya8 (33.67%) were found to be more contaminated with bacteria than mango 6(28.53%).This may be the water activity, antimicrobial constituents and/or nutrient content. The venders cause subsequent contamination during preparation, handling, by the side of waste disposal system, using water that is not boiled for dilution. Therefore, regular supervision and training about safe processing and handling of fruit juices and hygiene of venders can improve the quality of fresh fruit juices.

We report a case of a 14 year old male who presented with lower abdominal pain and passing grossly red urine intermittently for 20 days, having no history of sore throat, skin lesions,blurring of vision, hearing loss and similar family history.A full serology and urology workup was negative for any abnormality. Kidney biopsy revealed uniform thin and slender appearing GBM without any other structural abnormality.Though Immunohistochemistry (IHC) and genetic analysis were not done, a diagnosis of thin basement membrane nephropathy (TBMN), a genetically benign hematuria without kidney failure progression is made. Skin biopsy histopathological examination also revealed finding of thin basement membrane this needs to be differentiated from Alport’s syndrome (AS) which has worse prognosis. Probably this is the first case reported from India with descriptive investigations and findings. Due to rarity of this disease and non-availability of laboratory facility especially for kidney biopsy examination, diagnosis is often missed or delayed at primary health care centers especially when no associated proteinuria has yet developed.

Published: February 2023

According to Nugin et al. (2016) it is not always easy to determine the exact date of birth of every generation as the transitions have been found to be difficult to pinpoint. (9). According to Seemiller and Grace (2015), the representatives of generation Z were born between 1995 to 2010 and have already entered higher education. Reading online has become one of the most widely used sources of knowledge for learners, especially in the academic contexts (Zarrabi, 2015), thus it is not surprising that for generation Z visual media may as well have the most substantial impact whereas internet and smart devices are the main means of communication making it possible for every question to be answered immediately. Teachers nowadays are faced with a somewhat challenging task to meet the information obtaining needs and preferences of the new generation while belonging to the previous generation themselves. In order to cast light into the process of choosing the most suitable methods and materials as well as the devices for the learners of Generation Z, a research was started in Tallinn Health Care College, with an aim to investigate different generations´ text searching and reading strategies. Current article focuses on describing the preferred medium of text among the representatives of Generation Z. An online semi-structured questionnaire was conducted descriptive analysis conducted. The results direct authors toward further research to investigate the strategies of working with texts keeping in mind the characteristics of Generation Z in order to use the mediums and strategies to create effective learning possibilities in higher education.

Hybrid Composite Materials for Immobilization of Radionuclides in Liquid Radioactive Waste
Authors: GК Mamytbekov
Published: February 2023

The biphasic hybrid composite materials for immobilization and fixation of radionuclides of the Liquid Radioactive Waste (LRW) of the research water-water reactor KIR WWR-K have been studied. It was found that the hybrid compositions have a high synergistic effect regard to the sorption of radionuclides, especially 137Cs+ and 134Cs+ . The distribution coefficient of cesium radionuclides in the composite materials are 2 times higher in comparison with the those sorption activity in the mineral matrix. It has been established that the sorption of radionuclides by two-phase hybrid compositions is carried out by a combination of three mechanisms. Firstly, due to the electrostatic binding reaction between the functional groups of sorbents and metal ions stabilized by the system of coordination bonds with electron-donating nitrogen and oxygen atoms of the amino and carbonyl groups of the polymer matrix. Secondly, as a result of ion exchange between counterions of the mineral matrix and radionuclides ions in the environmental solution. Finally, due to the superequimolar absorption of radionuclides as a result of deformation of the crystal lattice of mineral fillers of the polymer matrix of bentonite and copper ferrocyanide, which increases their pore size. It has been shown that biphasic hybrid composite materials have an increased mechanical and radiation resistance while retaining elasticity even at high doses of electron irradiation, at which in despite on a noticeable decrease the value of deformation there is no significant decline in their compressive strength. The obtained information on the mechanism of binding of biphasic hybrid composite materials with various metal ions makes it possible to synthesize new classes of materials for selective sorption of certain types of radionuclides in the body of mineral and polymer matrices. This will allow us to use these materials as a highly effective sorption materials with a synergetic effect for the detection, identification, immobilization and fixation of LRW radionuclides.

Published: February 2023

In the article continuing education of social workers in the post-non-classical perspective is analyzed. It was found that continuing education is considered a component of continuing professional training of social workers and includes involvement in both formal, non-formal and informal education, and as well as continuous improvement of professional skills based on the integration of theory and practice. Social work professionals demonstrate that they are maintaining and enhancing their competence throughout their careers.Continuing education is a self-directed process, which requires social workers to assume responsibility for their own professional development.

Published: February 2023

The aim of this article is to investigate the personal and professional characteristics of future specialists in the process of their preparation in the post-classical paradigm in science. The contribution is in solving general problems related to the person in the complex self-organizing system: higher education-business-management, with a perspective of constructing adequate principles, methods, and realistic adequate measures of its new quality. Historical, interdisciplinary, and synergetic approaches of analysis reveal that personal-professional characteristics change, determine the type of presence (position) of the specialist that higher education prepares. Their change is related to new requirements imposed by each new era in the development of society in all its spheres. The analysis of different theories of management reveals the transition in the development of the personal-professional characteristics of the person, which goes from the "silent" (passive) subject in the classical era through the prepared, administrative-"orderly", creative non-classical subject to the self-organizing, self-learning, charged and giving energy to others post-classical subject-student and specialist. The future specialist with its characteristics is a necessary equal complement to the personal-professional characteristics of both the university teacher and the manager in the workplace.

Authors: Alotaibi Soultanh
Published: February 2023

The current study aimed to identify the attitudes of special education teachers towards evidence-based practices and discover the difference in their attitudes according to the following variables (type of specialization, educational stage, educational qualification, training), as well as discover the obstacles that prevent their application. To achieve these goals, the descriptive approach was used, which relied on the questionnaire as a tool for collecting data from the study sample of (314) female teachers. The results found that special education teachers have positive attitudes towards evidence-based practices, and the results also found that there is no difference between special education teachers’ attitudes towards evidence-based practices according to the variable of specialization, academic qualification, and educational stage, with the exception of training that resulted in a difference in attitudes in favor of the teachers who attended training courses. One of the main obstacles that prevent special education teachers from applying evidence-based practices was the lack of financial support allocated to provide the tools and devices needed to use evidence-based practices, limited communication between researchers and teachers to inform them of the most important evidence-based practices, and the lack of available sources for evidence-based practice.
