Hypersensitivity and Induced Radioresistance in Chinese Hamster Cells Exposed to Radiations with Different LET Values

We study the impact of radiation LET on manifestation of HRS/IRR response in Chinese hamster cells ovary cells exposed to radiations used in radiotherapy. Earlier we have investigated this response to carbon ions (455 MeV/amu) in the pristine Bragg curve plateau and behind the Bragg peak, 60Co γ-rays, and 14.5 MeV neutrons. Now we present results of cytogenetic metaphase analysis in plateau-phase CHO-K1 cells irradiated with scanning beam protons (83 MeV) at doses < 1 Gy and additional data for 14.5 MeV neutrons. Dose curves for frequency of total chromosome aberrations (CA, protons), paired fragments (protons, neutrons), aberrant cells (neutrons) had typical HRS/IRR structure: HRS region (up to 0.1 and 0.15 Gy), IRR region (0.1–0.6 Gy and 0.15–0.35 Gy) for protons and neutrons, respectively, and regular dose dependence. Taken together with previous results, the data show that LET increase shifts the HRS upper border (from 0.08–0.1 Gy for γ-rays, protons and plateau carbons to 0.12–0.15 Gy for “tail” carbons and neutrons). The IRR regions shortens (0.52–0.4 γ-rays and protons, 0.25 plateau carbons, 0.2 Gy “tail” carbons and neutrons). CA level of IRR increases by 1.5–2.5 times for carbons as compared to γ-rays and protons. Outside HRS/IRR the yield of CA also enhanced with LET increase. The results obtained for different LET radiations suggest that CHO-K1 cells with G1-like CA manifested the general feature of the HRS/IRR phenomena.
Accurate Adiabatic and Diabatic Potential Energy Surfaces for the Reaction of He + H2

The accurate adiabatic and diabatic potential energy surfaces, which are for the two lowest states of He + H2, are presented in this study. The Molpro 2012 software package is used, and the large basis sets (aug-cc-pV5Z) are selected. The high-level MCSCF/MRCI method is employed to calculate the adiabatic potential energy points of the title reaction system. The triatomic reaction system is described by Jacobi coordinates, and the adiabatic potential energy surfaces are fitted accurately using the B-spline method. The equilibrium structures and electronic energies for the H2 are provided, and the corresponding different levels of vibrational energies of the ground state are deduced. To better express the diabatic process of the whole reaction, avoid crossing points being calculated and conical intersection also being optimized. Meanwhile, the diabatic potential energy surfaces of the reaction process are constructed. This study will be helpful for the analysis of histopathology and for the study in biological and medical mechanisms.
Limitless Opportunities for Wealth? Witchcraft as a Strategy for (In)Equality and Economic (Dis) Empowerment

Abstract The persistence of witchcraft beliefs and practices in Africa contradicts earlier scholarly work that suggested it would disappear. In addition, theorising witchcraft as a local discourse that only exists between people in an intimate relationship in anthropology has also long been challenged. This strand of scholarship has sought to understand witchcraft within the local-global nexus pointing to a new direction in witchcraft studies. Unlike other themes in anthropology that began the discipline, witchcraft continues to be a ‘hot currency’ topic and has been termed by some scholars as the ‘long conversation’. This article presents a current ethnographic account of how witchcraft is utilised by individuals as a strategy for wealth gain and protection and serves as narrative for the challenges individuals are experiencing when having to navigate between often incompatible expectations placed on the individual vis-a-vis the community. This is further exemplified through the ethnographic account on how witchcraft strategies are employed against individuals who are pursuing success in neoliberal socio-economic model.
Social Media Addiction and Self-Esteem in relation to Gender of Students

Youth worldwide are increasingly exposed to social media and its consequences, and Bhutanese children are no exception. Owing to limited studies on the impacts of social media on students in Bhutan, this study investigates self-esteem and social media addiction, considering the gender of the students in the Zilukha Middle Secondary School, Thimphu, Bhutan. Out of 327 students, data were collected from 180 students (90 males and 90 females) using proportionate random sampling. The t-tests results revealed no significant difference in the social media addiction and self-esteem between male and female students. The study also found a significantly negative correlation between social media addiction and self-esteem of students. As social media addiction and self-esteem scores did not significantly differ between male and female students, parents and teachers need to monitor the use of social media by students irrespective of their gender. Similar studies in other parts of the country, particularly representing students in rural areas, are recommended for new social media addiction and self-esteem insights.
A Replication Study of Operations Management Experiments in Management Science

Over the last two decades, researchers in operations management have increasingly leveraged laboratory experiments to identify key behavioral insights. These experiments inform behavioral theories of operations management, impacting domains including inventory, supply chain management, queuing, forecasting, and sourcing. Yet, until now, the replicability of most behavioral insights from these laboratory experiments has been untested. We remedy this with the first large-scale replication study in operations management. With the input of the wider operations management community, we identify 10 prominent experimental operations management papers published in Management Science, which span a variety of domains, to be the focus of our replication effort. For each paper, we conduct a high-powered replication study of the main results across multiple locations using original materials (when available and suitable). In addition, our study tests replicability in multiple modalities (in-person and online) due to laboratory closures during the COVID-19 pandemic. Our replication study contributes new knowledge about the robustness of several key behavioral theories in operations management and contributes more broadly to efforts in the operations management field to improve research transparency and reliability. This paper was accepted by David Simchi-Levi, operations management.

The Hydration Status of Adult Patients with Oropharyngeal Dysphagia and the Effect of Thickened Fluid Therapy on Fluid Intake and Hydration: Results of Two Parallel Systematic and Scoping Reviews

Background: The effect of oropharyngeal dysphagia (OD) and thickened fluid (TF) therapy on hydration status has not been well defined in the literature. We aimed to assess the hydration status in patients with OD and the effect TF therapy has on it. Methods: Two literature reviews following PRISMA methodology (each one including a systematic and a scoping review) were performed: (R1) hydration status in adult patients with OD; (R2) effect of TF therapy on fluid intake and dehydration. Narrative and descriptive methods summarized both reviews. Quality assessment was assessed by Joanna Briggs Institute tools and GRADE. Results: (R1) Five out of twenty-two studies using analytical parameters or bioimpedance showed poorer hydration status among OD and 19–100% prevalence of dehydration; (R2) two high quality studies (total of 724 participants) showed positive effects of TF on hydration status. Among the articles included, nine out of ten studies that evaluated fluid intake reported a reduced TF intake below basal water requirements. Conclusions: Dehydration is a highly prevalent complication in OD. There is scientific evidence on the positive effect of TF therapy on the hydration status of patients with OD. However, strict monitoring of fluid volume intake is essential due to the low consumption of TF in these patients.

Introduction: The brain tumor is frequently related to severe motor impairment and impacts the quality of life. The corticospinal tract can sometimes be affected depending on the type and size of the neoplasm, so different tools can evaluate motor function and connections. It is essential to organize surgical procedures and plan the approach. Functional motor status is mapped before, during, and after surgery. Studying corticospinal tract status can help map the functional areas, predict postoperative outcomes, and help the decision, reducing neurological deficits, aiming to preserve functional networks, using the concepts of white matters localization and fibbers connections. Nowadays, there are new techniques that provide functional information regarding the motor cortex, such as transcranial magnetic stimulation (TMS), direct cortical stimulation (DCS), and navigated TMS (nTMS). These tools can be used to plan a customized surgical strategy and the role of motor evoked potentials (MEPs) is well described during intra-operative, using intraoperative neuromonitoring. MEPs can help to localize primary motor areas and delineate the cut-off point of resection in real-time, using direct stimulation. In the postoperative, the MEP has increased your function as a predictive marker of permanent or transitory neurological lesion marker. Methods: Systematic review performed in MEDLINE via PUBMED, EMBASE, and SCOPUS databases regarding the post-operative assessment of MEP in patients with brain tumors. The search strategy included the following terms: ((“Evoked Potentials, Motor”[Mesh]) AND “Neoplasms”[Mesh]) AND “Transcranial Magnetic Stimulation”[Mesh] AND “Brain Tumor”[Mesh]), the analysis followed the PRISMA guidelines for systematic reviews, the review spanned until 06/04/2021, inclusion criteria were studies presenting confirmed diagnosis of brain tumor (primary or metastatic), patients >18 y/o, using TMS, Navigated TMS, and/or Evoked Potentials as tools in preoperative planning or at the intra-operative helping the evaluation of the neurological status of the motor cortex, articles published in peer-reviewed journals, and written in English or Portuguese. Results: A total of 38 studies were selected for this review, of which 14 investigated the potential of nTMS to predict the occurrence of motor deficits, while 25 of the articles investigated the capabilities of the nTMS technique in performing pre/intraoperative neuro mapping of the motor cortex. Conclusion: Further studies regarding motor function assessment are needed and standardized protocols for MEPs also need to be defined.
Moderating effect of Perceived reMaining tiMe in the relationshiP between Job deMands and Job stress

This study aims to investigate the moderating effect of perceived remaining time on the relationship between job demands and job stress. Using the Conservation of Resources (COR) theory to explain the moderation effect, we argue that the relationship between job demands and job stress is weakened by perceived remaining time. Data were collected using online survey on public sector employees from 32 government institutions in Indonesia (N = 220). Data were analysed using Hayes’ PROCESS macro on SPSS software. Results showed that perceived remaining time moderated the relationship between job demands and job stress, such that the relationship was positive and higher when perceived remaining time was low than when perceived remaining time was high. Theoretical and practical implications are further discussed.
Monetary integration in South America: Elección of candidates through unsupervised machine learning

Applying Unsupervised Machine Learning techniques to a set of nominal variables (based on the optimum currency area [OCA] theory and the Maastricht Treaty criteria) and industrial indicators (based on similar production patterns), this paper aims to identify potential candidates for a monetary integration in South America (SA). The main conclusion is that, according to the clustering of the nominal and industrial indicators, the countries in best position for a hypothetical monetary integration in SA are Chile, Colombia, and Perú (and Ecuador to a lesser extent); countries that are generally members of the same cluster. This group of economies, which belong to the Pacific Alliance, are in a better position to meet various criteria for regional monetary integration, such as nominal convergence and similar production patterns.
The Effects Of Iron And Phosphorus Applications On The Yield and Yield Components In Chickpea

The research was conducted to determine effects of different levels of iron and phosphorus on the yield and some yield components in chickpea in 2017 in Van ecological conditions. The experiment was laid out in a factorial randomized block design with three replications. The doses were used phosphorus (0, 4 and 8 kg da) and iron (0, 1 and 2 kg da) in this study. In the study were investigated the plant height, first pod height, branch number per plant, pod, seed number and per plant, seed number per pod, biological yield, seed yield per unit, harvest index, 100-seed weight, protein ratio phosphorus content in seed, phosphorus content in seed and number of nodule. The results of the study indicated that iron and phosphorus applications increased significantly the seed yield and yield components. While the highest seed yield was obtained from 4 kg phosphorus /da + 1 kg iron /da application with 160.4 kg/da, the lowest seed yield was obtained from control parcels with 113.3 kg da. Yunus AKTAS
On braidings, syllepses, and symmetries

A constant voltage circuit has two rails 10 and 12, with one rail 12 at a variable potential V, possibly supplied by a voltaic cell. In one arm between the rails there is voltage reference means Z1, 14, with a circuit output line 16 connected thereto, and the line 16 is required to be maintained at a potential Vo, corresponding to a maximum value for V. In a second arm there is provided a first resistor R1, connected to the rail 12, and in series with a transistor T2. A second, equal, resistor R2 is connected between the output line 16 and the transistor T2. Means Z2, 30, T3, causes a potential, corresponding to the variable, decreasing, potential V, to be applied between the second resistor R2 and the transistor T2. The current to the transistor T2 is constant over a wide range dV for V, by a compensating current portion dI flowing through the second resistor R2, thereby maintaining V o constant. Usually, current gain means, such as a transistor T1, is provided, in the first arm, between the output line 16 and the rail 12.
simulation-based approach to a near optimal thinning strategy: allowing for individual harvesting times for individual trees

15 As various methods for precision inventories, such as LiDAR, are becoming increasingly common in 16 forestry, individual-tree level planning is becoming more viable. Here, we present a method for 17 finding the optimal thinning times for individual trees from an economic perspective. The method 18 utilizes an individual tree-based forest growth model that has been fitted to Norway spruce ( Picea 19 abies (L.) Karst. ) stands in northern Sweden. We find that the optimal management strategy is to thin 20 from above, i.e. harvesting trees that are larger than average. We compare our optimal strategy with 21 a conventional management strategy and find that it results in approximately 20% higher land 22 expectation value. Furthermore, we find that increasing the discount rate will, for the optimal 23 strategy, reduce the final harvest age and increase the basal area reduction. Decreasing the cost to 24 initiate a thinning (e.g., machinery-related transportation costs) increases the number of thinnings 25 and delays the first thinning.

: Despite growing interest in design science research in information systems, our understanding about what constitutes a design contribution and the range of research activities that can produce design contributions remains limited. We propose the design research activity (DRA) framework for classifying design contributions based on the type of statements researchers use to express knowledge contributions and the researcher role with respect to the artifact. These dimensions combine to produce a DRA framework that contains four quadrants: construction, manipulation, deployment, and elucidation. We use the framework in two ways. First, we classify design contributions that the Journal of the Association for Information Systems ( JAIS ) published from 2007 to 2019 and show that the journal published a broad range of design research across all four quadrants. Second, we show how one can use our framework to analyze the maturity of design-oriented knowledge in a specific field as reflected in the degree of activity across the different quadrants. The DRA framework contributes by showing that design research encompasses both design science research and design-oriented behavioral research. The framework can help authors and reviewers assess research with design implications and help researchers position and understand design research as a journey through the four quadrants.
Cigarette smoke or exhaust gas from waste incineration – where are more dioxins?

In Poland, incineration is a relatively new method of waste treatment. Modern installations for waste incineration have two functions: they reduce the quantity (volume) of the waste and are a source of electricity and/or heat. During all combustion processes including waste incineration, polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCD/Fs) (well known as dioxins) are formed. These compounds are considered to be extremely dangerous for living organisms including human beings. Dioxins are formed in any process of combustion of solid and liquid fuels in the presence of chlorine, oxygen and organic matter at appropriate temperatures. Combustion processes also occur during cigarette smoking, which is also a source of dioxin emissions. Although smoking has been classified as a less important source of dioxins in the environment, it directly affects our health. This work’s aim is to determine and compare the degree of harmfulness caused by the amount of inhaled dioxins: cigarette smoking or living near a waste incineration plant. Based on literature and experimental data, the concentration of dioxins in cigarette smoke and exhaust gases generated by municipal waste incineration plants as well as number of dioxins absorbed per day by the body will be presented.
Mediterranean aerosol radiative forcing and influence of the single scattering albedo

[1] Ground-based measurements of aerosol optical depth and surface shortwave irradiance carried out at the Mediterranean island of Lampedusa during 2004–2007 are used to estimate the surface aerosol direct radiative forcing for desert dust (DD), urban/industrial-biomass burning (UI-BB), and mixed aerosols (MA). The aerosol single scattering albedo, ω, at 415.6 and 868.7 nm is derived at 60° solar zenith angle, θ, from measurements of global and diffuse radiation using radiative transfer model calculations. The shortwave forcing efficiency (FES) is derived, for θ between 20° and 75°, for the three identified classes of aerosol and for all the observed data (AD). The absolute value of FES decreases for increasing θ for all the aerosol types. FES varies between −185 and −81.7 W m−2 for DD, −168 and −84 W m−2 for UI-BB, −251 and −120.2 W m−2 for MA, and −208 and −106.5 W m−2 for AD. The daily average forcing efficiency (FEd) at the equinox is −67.2 W m−2 for DD, −59.0 W m−2 for UI-BB, and −93.2 W m−2 for MA. The forcing efficiency of DD, UI-BB, and MA at θ = 60° was calculated for three intervals of single scattering albedo (0.7 ≤ ω < 0.8, 0.8 ≤ ω < 0.9, 0.9 ≤ ω ≤ 1) at 415.6 and 868.7 nm. The absolute value of FES decreases with increasing ω at 868.7 nm for all aerosol types, while it decreases with increasing ω at 415.6 nm for UI-BB and MA and increases for DD. A 0.1 increment in the single scattering albedo at 868.7 nm produces a reduction in FES by 25–30 W m−2, and a reduction by 10–15 W m−2 in FEd.
TORUS ACTIONS AND NON-NEGATIVE CURVATURE

A torus manifold M is a 2n-dimensional orientable manifold with an effective action of an n-dimensional torus such that M T 6 ∅. In this paper we discuss the classification of torus manifolds which admit an invariant metric of non-negative curvature. If M is a torus manifold which admits such a metric, then M is diffeomorphic to a quotient of a free linear torus action on a product of spheres. We also classify rationally elliptic torus manifolds up to rational homotopy equivalence and homeomorphism.

Uniform representation of recursively enumerable sets with simultaneous rigid E-unification

Recently it was proved that the problem of simultaneous rigid E-uniication (SREU) is undecidable. Here we perform an in-depth investigation of this matter and obtain that one can use SREU to uniformly represent any recursively enumerable set. From the exact form of this representation follows that SREU is undecidable already for 6 rigid equations with ground left hand sides and 2 variables. There is a close correspondence between solvability of SREU problems and provability of the corresponding formulas in intuitionistic rst order logic with equality. Due to this correspondence we obtain a new (uniform) representation of the recursively enumerable sets in intuitionistic rst order logic with equality with one binary function symbol and a countable set of constants. From this result follows the undecidability of the 99-fragment of intuitionistic logic with equality. This is an improvement of a recent result regarding the undecidability of the 9-fragment in general.
Evidence for magnetic reconnection in solar flares

From a study of the magnetic field topology in an active region, evidence is derived that solar flares are produced by magnetic reconnection. We study a complex group with two active regions (AR 2511 and AR 2512) for three consecutive days, June 13-15 1980. The observed longitudinal magnetic field is used to model the coronal magnetic field by the potential field created by a series of magnetic charges. This computed field matches satisfactorily the Hα fibrils and the observed transverse field direction. A set of flares occurs principally in the northern group (AR 2511). During these three days, two different magnetic configurations in succession are responsible for the occurrence of these flares: first the intrusion of a new opposite flux in the following polarity, secondly the emergence of new flux between the main polarities
