Abundance and Distribution Patterns of Megadrilli Earthworms at Different Altitude in Kabawetan Tea Plantation, Bengkulu

Earthworms are an important component of natural and agricultural land ecosystems. The existence of earthworms in agricultural land can increase soil fertility and also support a sustainable agricultural system. This study aims to determine the abundance and distribution patterns of megadrilli earthworms in the Bengkulu Kabawetan Tea Plantation. Determination of the research location used the stratified sampling method which consisted of altitude strata, namely an altitude of 800, 900, and 1000 meters above sea level. The samples of earthworms were taken using the quadratic method (30 x 30 x 20 cm) and the hand sorting method as many as 15 plots for each location. The data were analyzed for population densities and distribution patterns using the Morisita Index formula. The results showed that only one species of megadrilli earthworm was found Pontoscolex corethrurus in tea plantations. The highest earthworm population density was at a location of 1000 m above sea level (89.66 individuals m), followed by a location of 900 m (70.33 individuals m), and the lowest density was at a location of 800 m (24.44 individuals m). Statistically, it showed that the densities of the earthworm population at an altitude of 1000 m and 900 m were not significantly different, but it was significantly different from an altitude of 800 m. The distribution pattern of megadrilli earthworms based on the Morisita Index value showed that the three locations have a clustered pattern.
Different pollination approaches to compare the seed set of diploid and tetraploid red clover
 Trifolium pratense
 L.

production, low yield is limiting the commercial exploitation of tetraploid red clover. To explore if pollination is the limiting factor for the seed yield in tetraploid red clover, we investigated pollinator behaviour and plant reproductive success in diploid (2x) cultivar ‘Rajah’ and tetraploid (4x) cultivar ‘Amos’ using honey bee and hand pollination approaches. We measured the seed set at the flower head level with the increasing visitation rate of honey bees (one bee, two bees and open pollination) and pollen diversity (one and two pollen donors) of hand pollination. We found no difference in honey bee pollination behaviour (visitation rate) between the diploid and tetraploid red clover. Surprisingly, the seed set in two bees was significantly lower than that of one bee in ‘Rajah’. We suggest that honey bees prefer to visit already tripped florets or to visit fewer florets due to scent marks left by the previous honey bees. In open pollination, seed number per flower head in ‘Amos’ (on average 11) was half of ‘Rajah’ (on average 20). Seed set in ‘Amos’ was lower than 50% of ‘Rajah’ in honey bee (one bee treatment) and hand pollination (one and two pollen donors treatments). There were no differences in stigma receptivity whereas pollen viability in ‘Amos’ was lower than ‘Rajah’ after the peak pollen viability was reached (six days after the onset of flowering). We suggest that the fertility problems such as low pollen viability may be the reason for the low seed set in tetraploid red clover. This conclusion should be verified by investigating other fertility traits during the ovary, embryo and seed development with a broader range of diploid and tetraploid cultivars.
Distance Protection for Coexistence of 5G Base Station and Satellite Earth Station

In this paper, we investigate the coexistence of the 5G communication network with a fixed-satellite service (FSS) in the 3.5 GHz and 26 GHz frequency bands. We analyze a distance protection scheme for the FSS Earth station (ES) and 5G base stations (BS). Furthermore, we define the exclusion and restriction zones to develop a transmit power control scheme based on the Citizens Broadband Radio Service (CBRS). An interactive power control scheme is also devised for the restriction zone and extensively analyzed through simulations. The proposed scheme is examined for practical scenarios such as the rural macrocells (RMa), urban macrocells (UMa), and urban microcells (UMi) as defined by the 3GPP. The impact of the antenna type is also investigated, and BSs with omnidirectional, 4 × 4, 8 × 8, and 16 × 16 antenna arrays are examined, as defined by 3GPP, for the 5G networks. The results confirm that 5G systems can coexist with the FSS and provide quantitative insights into the selection of the system parameters, including interference margins, exclusion sizes, and reduction zones, for different scenarios and antenna types.
Modeling of Eucalyptus globulus Kraft Pulping

The optimization of kraft pulping covering both continuous and batch processes demands kinetic models suitable for advanced control and offline optimization of the cooking operation. This work contributes to an improved kinetic model for kraft cooking of Eucalyptus globulus suitable for advanced control of modern displacement cooking processes such as the continuous batch cooking process (CBC). After impregnation where the initial lignin has been removed, the bulk and residual delignification have been studied in a batch reactor as a function of the [OH], [HS], ionic strength, [Na], and temperature. The underlying kinetic expressions are similar to those used in the Andersson model also including a mechanism for determining the distribution of lignin and carbohydrate species 2 and 3 as a function of the cooking conditions. The kinetic equations were successfully validated against experimental data from a pilot plant digester applying conventional batch cooks.
Deterioration of the Corticobulbar Tract in Older Dysphagic Patients Without Neurologic Diseases

Objectives Less is known how dysphagia affects older patients without neurologic diseases and whether the symptoms of dysphagia have any association with impaired central control of swallowing. This study investigated the state of the corticobulbar tract, the surrogate marker for the central control of swallowing, in older dysphagic patients without any neurologic diseases, using diffusion tensor tractography. Design This retrospective observational study was conducted at a tertiary university hospital including 10 patients 60 yrs or older with oropharyngeal dysphagia without neurological disease and 11 age- and sex-matched control participants. The corticobulbar tract was reconstructed, and the fractional anisotropy and tract volume were measured using diffusion tensor tractography. Results The corticobulbar tracts of the dysphagia group were narrowed and not reconstructed by their configurations and had lower fractional anisotropy and tract volume values when compared with those of control group. Significant asymmetry between the left and the right corticobulbar tract hemispheres was found in the dysphagia group, whereas no asymmetry was found in the control group. Conclusions A deteriorated corticobulbar tract could be associated with the development of dysphagia in older adults without neurological diseases. Our findings might help establish more appropriate treatment strategies, such as targeted neuromodulation therapies in the future.
Response Options and the Measurement of Political Knowledge

Abstract By many measures, the public knows little about politics. But just how little people seem to know depends on the questions that are put to them. In particular, knowledge levels seem higher when people are asked closed- rather than open-ended questions. In turn, differences between estimated knowledge levels are sometimes attributed to fundamental differences between these types of questions. Building on this previous research, the present study uses a pre-registered experiment conducted with a representative national sample to shed new light on the relationship between question form and knowledge measurement. The authors find that inferences about political knowledge depend less on fundamental differences between open- and closed-ended questions than on two little-appreciated aspects of survey design: the number and difficulty of the response options that accompany closed-ended questions. These aspects of survey design have large effects. Scholars who use the same questions with different response options may reach substantively different conclusions about the public's levels of knowledge.
Synthesis, Characterization, and Properties of Rivaroxaban New Crystalline Forms

In this paper, two new Rivaroxaban crystalline forms are reported and characterized by the single‐crystal X‐ray diffraction (SXRD), powder X‐ray diffraction (PXRD), thermogravimetric analysis, and differential scanning calorimetry (TGA/DSC), which are synthesized with formic acid and acetic acid, named as forms F and G, respectively. The intermolecular forces for forms F and G are analyzed by Hirshfeld surface analysis method, showing that the force of O···H is significantly stronger than that of H···H. Furthermore, the stability, solubility, and bioavailability of the two crystal forms are also studied. The clinical experiments show that form F is more effective than other reported crystal forms in inhibiting the activity of thrombin and thrombosis, which is expected to replace the marketed crystalline forms in clinical application.
Emotional Distress, Neurobehavioral Symptoms, and Social Functioning among Treatment Seeking Service Members with TBI and PTSD Symptoms

Abstract This study examined the combined effects of traumatic brain injury (TBI) history and posttraumatic stress disorder (PTSD) symptoms on social functioning in treatment-seeking active duty service members. We sought to determine whether objective cognitive performance, self-reported neurobehavioral symptoms, and emotional distress would be associated with more social functioning difficulties. Additionally, we hypothesized self-reported neurobehavioral symptoms would mediate both the relationships between emotional distress and social functioning, and between cognitive performance and social functioning. The study was part of a larger clinical project conducted at two military hospitals. We analyzed smaller datasets of baseline data from two groups: service members with history of TBI and/or PTSD (n = 71) and those with responses considered “valid” (n = 39). A significant predictive relationship among cognitive performance, neurobehavioral symptoms, and emotional distress on social functioning was found in the full sample. Further, neurobehavioral symptoms completely mediated the relationship between emotional distress and social functioning, but not between cognitive performance and social functioning. In the subsample, the overall regression was significant, but individual independent predictors were not. Findings suggest emotional distress and self-reported neurobehavioral symptoms are key considerations in treatment as a means of improving functioning in social domains and prioritizing treatment goals.
Undergraduate Nursing Students’ Challenges when Writing Research Proposals at the University of Namibia

Research topic selection and problem formulation are prerequisites when preparing a proposal for conducting research. However, nursing students find this a daunting task when doing it for the first time, despite the research methodology module that introduces nursing students to research. Institutions of higher learning should, therefore, establish the challenges that undergraduate nursing students face when writing their research proposals to develop strategies in order to mitigate these challenges. In Namibia, students’ challenges when writing research proposals have not been extensively researched. This study aimed to explore and describe undergraduate nursing students’ challenges when writing research proposals at the University of Namibia (UNAM), with a view to describing the factors that affect this. Accordingly, a qualitative, explorative, descriptive and contextual design was applied and purposive sampling was used to select 20 undergraduate nursing students enrolled for the Bachelor of Nursing Science (Clinical) (Honours) at UNAM. Individual interviews were conducted, using semi-structured interviews in line with an interview guide. Data were analysed by means of qualitative thematic analysis, which identified the following themes: challenging experiences when writing the research proposal; influence of the supervisor; and recommendations for improvement. The findings of this study call for well-articulated plans and actions from the lecturers and supervisors involved to address the challenges highlighted in this study, as well as actions and plans that should inform the curriculum. A need was identified for a strong focus on library information literacy and English for academic writing to be taught simultaneously with the writing of research proposals from the third year.

Review on the ecophysiology of important Andean fruits: Solanaceae

The high Andean areas present ecophysiological conditions suitable for the cultivation of many fruit species, especially of the Solanaceae family. The objective of this review is to present important ecophysiological information on four fruit trees grown in cold climates: Cape gooseberry, tree tomato, lulo, and sweet cucumber o pear melon. The cape gooseberry is a species well adapted to cold tropical climate, it is grown between 1,800 and 2,700m a.s. l. , with temperatures of 13 to 16°C. It is highly adapted to high solar radiation and to the abrupt changes between the day and night temperatures. It requires a precipitation of 1,000 to 1,800mm year-1 uniformly distributed throughout the year, and is sensitive to water deficit but also to waterlogging and strong winds. The tree tomato, in Colombia, produces better from 1,800 to 2,600m a.s. l. , with temperatures between 13 and 20°C, annual rainfall between 1,500 and 2,000mm, relative humidity around 80%, and solar brightness of 1,800 to 2,300 hours/year; it does not resist strong winds, water deficit or waterlogging. The lulo requires environments with high precipitation (1,000 to 2,800mm) and penumbra because it loses a lot of water through transpiration but waterlogging also affects it; it grows well in areas between 1,600 to 2,400m a.s. l. and 16 to 24°C, with photosynthesis rates up to of 34. 03µmol CO2 m-2 s-1. The sweet cucumber is of growing interest in many exotic fruit markets, it grows at 900-2,800m a.s. l. with temperatures <25°C and responds well to air enrichment with CO2.
Cancer-associated Molecular Abnormalities in Human NK cells

Natural Killer (NK) cells play a key role in the immune responses against infection and cancer as powerful cytotoxic effector cells and regulators of both innate and adaptive immunity [1,2]. Therefore, defects in NK cell functions are important mechanisms for immune evasion of malignant cells [3]. For instance, the ability of tumor cells and tumor-associated stromal/infiltrating cells to inhibit NK cell activity, which results in preventing NK cells from recognizing and killing tumor cells, has been reported for melanoma, neuroblastoma, gastrointestinal sarcoma, hepatocellular cancer (HCC), pancreatic cancer, colorectal carcinoma and other types of cancer [4-9]. A potential loss of NK cell numbers and function at preneoplastic stages of tumorigenesis as a possible mechanism for cancer induction and progression has been also recently proposed [5,10]. However, molecular mechanisms regulating NK cell dysfunction and exhaustion in cancer are largely unclear.
Designing liquid-crystalline dendronised hexa-adducts of [60]fullerene via click chemistry

ABSTRACT Liquid-crystalline [60]fullerodendrimers were constructed via click chemistry based on the reaction between hexa-adducts of [60]fullerene (C60) bearing 12 azide groups and alkyne-terminated cyanobiphenyl dendrons of first- and second-generation. The structure of all the new compounds was confirmed by IR, UV, 1H and 13C NMR spectroscopies and mass spectrometry. The mesomorphic properties were studied by polarised optical microscopy, differential scanning calorimetry and small-angle X-ray scattering. The hexa-adduct of C60 functionalised with the first-generation dendrons gave rise to the formation of a smectic A phase and a rectangular columnar phase (c2mm symmetry) while the hexa-adduct of C60 decorated with the second-generation dendrons displayed only a rectangular columnar phase (c2mm symmetry). Our results show that the hexa-adduct of C60 is a unique synthetic platform for the design of fullerodendrimers and dendronised materials. GRAPHICAL ABSTRACT
Spatial and Temporal Planetary Boundary Layer Moisture‐Source Variability of Crimean Peninsula Precipitation

The atmospheric water cycle is a key component of the global energy and moisture exchange. In order to gain better understanding of the atmospheric processes and temporal variability and trends affecting precipitation in Crimea, we use a Lagrangian moisture source detection technique based on reanalysis data from the European Center for Medium‐Range Weather Forecasts. The study presents a quantitative picture of the major moisture sources that feed precipitation on the Crimean peninsula from February 1979 to January 2017. In total 51.3% of moisture stems from marine sources. Specifically, the main individual contributors are the Mediterranean Sea (15.3%), the Black Sea (14.4%), and the North Atlantic Ocean (13.9%). Continental moisture recycling contributes additional 46.9%. The amounts of moisture contribution from marine and continental sources and their respective moisture transport pathways are subject to strong seasonality. Winter precipitation in Crimea is predominantly sourced by the Mediterranean Sea. Long‐term temporal trends in contribution from any of the major moisture sources are absent during the study period. Statistically significant negative correlation between the North Atlantic Oscillation (NAO) index and contribution from moisture sources exists in winter for the Mediterranean (R = −0.22) and Black Seas (R = −0.23), and for the southern continental moisture source (R = −0.37). The North Atlantic Ocean moisture source exhibits a statistically significant positive correlation with NAO index during spring (R = 0.32).
Bridging the Gap from the Other Side: How Corpora Are Used by English Teachers in Norwegian Schools

Researchers have written of ‘bridging the gap’ between corpus linguistics and teaching practice. This study focuses on in-service English teacher informants from Norwegian schools, to try to address the ‘gap’ from the teaching practice ‘side’, rather than from the linguist ‘side’ engaged in spreading corpus linguistics. The study collects data on teachers’ familiarity with corpus linguistics, what corpora are used for and how, and teachers’ views on the obstacles to corpus use. The research question is How are corpora used by in-service English teachers in Norwegian schools? The research design consists of an online questionnaire and follow-up interviews. The questionnaire was answered by 210 teachers, 34 of whom answered they had done some work with corpora. The interviews were with three corpus-using teachers. The corpora they used were GloWbE, SkELL, Netspeak and COCA. Teacher-corpus interaction was for reference and for creating vocabulary and varieties of English exercises, and pupil-corpus interaction was encouraged by two of the teachers. The obstacles to the use of corpora were identified as differences between school levels, usability, and lack of teacher need. In concluding remarks, it is suggested that a starting point for corpus use among teachers may be to teach the tools and methods that seem to be already working for in-service teachers.
Acoustic and visual adaptations to predation risk: a predator affects communication in vocal female fish

Abstract Predation is an important ecological constraint that influences communication in animals. Fish respond to predators by adjusting their visual signaling behavior, but the responses in calling behavior in the presence of a visually detected predator are largely unknown. We hypothesize that fish will reduce visual and acoustic signaling including sound levels and avoid escalating fights in the presence of a predator. To test this we investigated dyadic contests in female croaking gouramis (Trichopsis vittata, Osphronemidae) in the presence and absence of a predator (Astronotus ocellatus, Cichlidae) in an adjoining tank. Agonistic behavior in T. vittata consists of lateral (visual) displays, antiparallel circling, and production of croaking sounds and may escalate to frontal displays. We analyzed the number and duration of lateral display bouts, the number, duration, sound pressure level, and dominant frequency of croaking sounds as well as contest outcomes. The number and duration of lateral displays decreased significantly in predator when compared with no-predator trials. Total number of sounds per contest dropped in parallel but no significant changes were observed in sound characteristics. In the presence of a predator, dyadic contests were decided or terminated during lateral displays and never escalated to frontal displays. The gouramis showed approaching behavior toward the predator between lateral displays. This is the first study supporting the hypothesis that predators reduce visual and acoustic signaling in a vocal fish. Sound properties, in contrast, did not change. Decreased signaling and the lack of escalating contests reduce the fish’s conspicuousness and thus predation threat.
Understanding the structure of cognitive noise

Human cognition is fundamentally noisy. While routinely regarded as a nuisance in experimental investigation, the few studies investigating properties of cognitive noise have found surprising structure. A first line of research has shown that inter-response-time distributions are heavy-tailed. That is, response times between subsequent trials usually change only a small amount, but with occasional large changes. A second, separate, line of research has found that participants’ estimates and response times both exhibit long-range autocorrelations (i.e., 1/f noise). Thus, each judgment and response time not only depends on its immediate predecessor but also on many previous responses. These two lines of research use different tasks and have distinct theoretical explanations: models that account for heavy-tailed response times do not predict 1/f autocorrelations and vice versa. Here, we find that 1/f noise and heavy-tailed response distributions co-occur in both types of tasks. We also show that a statistical sampling algorithm, developed to deal with patchy environments, generates both heavy-tailed distributions and 1/f noise, suggesting that cognitive noise may be a functional adaptation to dealing with a complex world.
