Students’ perception toward Interactive Game to Facilitate Student’s Achievement

Abstract . This research was conducted to find out the students’ perception toward game interactive to facilitate student’s achievement. The approach used in this research is a qualitative approach in a descriptive research. The design of this study is qualitative research. The participant in this research is eight undergraduate students’ at Ahmad Dahlan University. It was used purposive sampling technique. The data collections were open ended interview as the instrument. Qualitative approaches use more open-ended approaches that ask general-level questions, and the participants can shape the possibilities responses . Open-ended interview with these key aim: to know how student’s perception toward interactive game “Kahoot’ and how is the students’ perception toward their achievement in learning process. The result of this research showed that All participants agreed that using Kahoot! triggers positive attention and increases focus in class. That students easily focus and unconsciously concentrate fully on the material while using Kahoot, students find it easier to collaborate and interact with friends and also the teacher for problem solving development, on the other hand the intellectual intelligence of students on the content of Kahoot can be made to encourage students to explore every material taught and finally students are not bored and very enjoy learning through interactive games, this indirectly makes students more intense in receiving material. Therefore, it can be concluded that the interactive game Kahoot! has a good impact to student`s achievement.
Phase noise analysis of source injection coupled quadrature oscillator

This paper analyzes the thermally induced phase noise and the up‐conversion of flicker noise into phase noise of source injection coupled quadrature oscillator (SIC‐QOSC), for the first time. Furthermore, this paper provides a complete analysis for the injection current of the SIC‐QOSC and extracts the closed‐form expressions for it for the first time, too. These expressions lead to obtaining the harmonics of the injection current as well as the oscillation amplitude, which is necessary for the phase noise analysis. To evaluate the extracted equations, this paper compares the calculated results with appropriate simulations. Comparisons confirm the accuracy of the proposed injection current expressions and the phase noise formulas. Using the closed‐form equations of phase noise, designers can understand the SIC‐QOSC's design tradeoffs and design the oscillator for given phase noise.
Grain legume–cereal intercropping: The practical application of diversity, competition and facilitation in arable and organic cropping systems

Abstract Intercropping is the simultaneous cultivation of more than one crop species on the same piece of land and is regarded as the practical application of basic ecological principles such as diversity, competition and facilitation. Field experiments were carried out on a sandy loam soil and a sandy soil in Denmark over three consecutive cropping seasons including dual grain legume (pea, faba bean and lupin)–barley intercropping as compared to the respective sole crops (SC). Yield stability of intercrops (IC) was not greater than that of grain legume SC, with the exception of the IC containing faba bean. Faba bean and lupin had lower yield stability than pea and fertilized barley. However, the different IC used environmental resources for plant growth up to 50% (LER=0.91–1.51) more effectively as compared to the respective SC, but with considerable variation over location, years and crops. The SC performance supported the interspecific interactions within the IC stand. On the sandy loam 13% greater grain yield of pea cv. Agadir (520 g m−2) was observed as compared to cv. Bohatyr. Faba bean and lupin yielded similarly (340 g m−2) in the sandy loam soil, with decreasing yields on the sandy soil (320–270 g m−2). Nitrogen fixation was very constant in grain legume SC over species and location, varying from 13.2 to 15.8 g N m−2, being lowest in peas and highest in faba bean and lupin. The intercropped grain legumes increased the proportion of plant N derived from N2-fixation by on average 10–15% compared to the corresponding SC. However, especially lupin was suppressed when intercropping, with a reduced N2-fixation from 15 to 5–6 g N m−2. The IC were particularly effective at suppressing weeds, capturing a greater share of available resources than SC. Weed infestation in the different crops was comparable; however, it tended to be the highest in sole cropped faba bean, lupin and unfertilized barley, where the application of urea to barley reduced the weed infestation by around 50%. Reduction in disease was observed in all IC systems compared to the corresponding SC, with a general disease reduction in the range of 20–40%. For one disease in particular (brown spot on lupin) disease reduction was almost 80% in the IC. Intercropping practices offer many advantages but improved understanding of the ecological mechanisms associated with planned spatial diversity, including additional benefits with associated diversity, is needed to enhance the benefits achieved.
Tumor Necrosis Factor α-induced Vascular Leakage Involves PECAM1 Phosphorylation

Abstract Herein we show that exposure of human umbilical vein endothelial cells to tumor necrosis factor α (TNFα) led to platelet endothelial cell adhesion molecule-1 (PECAM1) surface redistribution, disruption of cytoskeleton connections, and increased PECAM1 phosphorylation, accompanied by increased permeability to macromolecules. The in vitro use of inhibitors of tyrosine or serine-threonine kinases could prevent both PECAM1 surface redistribution and the increase in permeability induced by the cytokine. In vivo administration of lavendustin A, a natural tyrosine kinase inhibitor, protected endothelial cells from TNFα-dependent vascular leakage in mouse liver. We propose that the involvement of PECAM1 in TNFα-mediated effects on vascular permeability may depend on a dynamically regulated cytoskeletal association, related to the degree of PECAM1 phosphorylation.
The Solidus and Melt Productivity of Nominally Anhydrous Martian Mantle Constrained by New High Pressure‐Temperature Experiments—Implications for Crustal Production and Mantle Source Evolution

We constrained the solidus of a model Martian composition with low bulk Mg# (molar MgO/(MgO + FeOT) × 100 ~75) and high total alkali (Na2O + K2O = 1.09 wt.%) concentration at 2 to 5 GPa by experiments. Based on the new solidus brackets, we provide a new parameterization of the solidus temperature as a function of pressure of Martian mantle: Ts(°C) = − 5P (GPa)2 + 107P(GPa) + 1,068. The newly constrained solidus of the Lodders and Fegley (1997; https://doi.org/10.1006/icar.1996.5653) model Martian composition (LF composition) is 20 to 90 °C lower than the previous solidus of model Martian mantle with lower total alkali (~0.54 wt.%). The supersolidus experiments yield an average isobaric melt productivity, dF/dT, of 20 ± 6 wt. %/100 °C. We also bracketed the solidi of model Martian mantle compositions with low Mg# (~75) and low alkali (~0.54 wt.%), and with high Mg# (~80) and low alkali (~0.54 wt.%) at a constant pressure of 3 GPa. We find that bulk Mg# enhances the solidus temperature and bulk total alkalis suppress it. A parameterization that estimates the effect of bulk Mg# and total alkalis on peridotite solidus, including Mars and Earth, at 3 GPa can be described as: Ts(°C) = 4.23Mg # − 85(Na2O(wt. %) + K2O(wt. %)) + 1,120. Based on the new solidus parameterizations, 10–40 km more Martian crust would be produced by columnar decompression melting for LF model composition compared to the low Mg#‐low alkali model composition. The quantitative constraints on the solidus shift with Mg# and total alkalis from this study can be used to assess the Martian mantle solidus change through melting and melt extraction over time and the role of mantle heterogeneity in crustal production.
Analysis of diversity and function of the human small intestinal microbiota

The gastrointestinal (GI) tract is the main site where the conversion and absorption of food components takes place in humans. As the small intestine is the first site of interaction between the microbiota and ingested food, knowledge about the microbial composition as well as functionality is essential for a complete understanding of the symbiotic interactions and to the potential modulation of metabolically important groups. Subjects carrying an ileostomy were chosen as model system and ileostomy effluent samples were collected over time. The diversity as well as activity of the inhabiting microbiota was analysed in ileostomy effluent samples of five healthy individuals, collected in the morning and afternoon over a period of 28 days. This revealed that the diversity of the ileostomy effluent microbiota was different from that in the faeces, mainly concerning the lower complexity and stability over time. In terms of composition the relative abundance of species belonging to the genera Streptococcus and Veillonella was higher, whereas a lower relative abundance of species related to the Ruminococcus obeum, R. gnavus and Bacteroides plebeius-like organisms was observed in ileostomy effluent samples. Marked differences in microbiota composition between the five subjects with an ileostomy were found, indicative for a highly personal ileal microbiota profile. Differences in microbiota composition profiles were observed over time, even visible within one day, although the overall fluctuations were around a relatively large stable core group, consisting of species belonging to three streptococci-related groups (S. bovis, S. intermedius and S. smitis), Clostridium cluster I, Enterococcus, Veillonella and Oxalobacter formigenes. Overall, the data presented in this thesis indicated that the genus Streptococcus is not only numerically abundant, but also predominates randomly generated metabolic activity profiles of the microbial ecosystem of the ileostomy effluent microbiota. Predominant functions exerted were related to metabolism, especially carbohydrate metabolism and transport. The fast transit of the ileal contents appears to generate an environment in which the capacity to rapidly metabolise the available carbohydrates is an important selective advantage.
Legitimacy & Accountability in Government-NGO Relationships.

This paper examines the dynamics in relationships between Non-governmental Organizations (NGOs) and government and how NGOs may seek to effectively influence society and the ways in which it operates within such a relationship and vice versa. NGO-government relationships occur across the globe, in many contexts, and for many reasons. These reasons may include the continued survival of the NGO and/or to consult on complex issues and policies. These alliances are often nuanced with power struggle and conflicts of interest and legitimacy. However, this paper will argue that government-NGO relationships can increase NGO legitimacy, affording them access to traditional structures of the political arena.
Analyses of CRN effectors (crinkler and necrosis) of the oomycete aphanomyces euteiches

L'oomycete Aphanomyces euteiches est un pathogene racinaire de legumineuses cultivees (pois, luzerne. . . ) et de la plante modele Medicago truncatula. Les oomycetes, comme d'autres microorganismes pathogenes eucaryotes, secretent et transloquent des molecules a l'interieur des cellules de l'hote (effecteurs intracellulaires/cytoplasmiques) dans le but de manipuler les fonctions de la plante et de faciliter l'infection. Les proteines CRN (Crinkling and Necrosis) constituent une famille d'effecteurs nucleaires largement repandue chez les oomycetes et recemment decrites chez des especes fongiques. Leurs cibles et role dans la virulence ainsi que leurs mecanismes de secretion et de translocation sont encore mal compris. Nous avons entrepris la caracterisation fonctionnelle des proteines AeCRN5 et AeCRN13 d'A. Euteiches ainsi que de l'homologue d'AeCRN13 du champignon pathogene d'amphibien Batrachochytrium dendrobatidis, BdCRN13. Les analyses d'expression genique et proteique ont permis de montrer que AeCRN5 et AeCRN13 sont exprimes durant l'infection des racines de M. Truncatula. Des resultats preliminaires d'immuno-localisation d'AeCRN13 ont revele, pour la premiere fois, la secretion et translocation d'un CRN durant l'infection. Leur expression heterologue, a la fois dans les cellules de plantes et d'amphibiens, a montre que ces proteines se localisent dans les noyaux ou leurs activites conduisent a la perturbation de la physiologie de l'hote. En developpant un systeme in vivo base sur la technique de FRET-FLIM, nous avons demontre que ces CRN ciblent les acides nucleiques: AeCRN5 cible l'ARN des plantes tandis qu'AeCRN13 et BdCRN13 lient l'ADN. Ces deux effecteurs CRN13 exhibent un motif de type HNH, lequel est typiquement retrouve dans des endonucleases. Nous avons demontre que les CRN13 presentent une activite nuclease in vivo conduisant a la generation de coupures double brin de l'ADN. Ce travail a permis de mettre en evidence un nouvel mecanisme d'action des effecteurs de microorganismes eucaryotes et apporte des nouveaux aspects pour la comprehension de l'activite des proteines CRN d'oomycete mais aussi, pour la premiere fois, de champignon.

Etude de la réplication du VHB et de la réponse à l'intracellulaire à l'infection virale

Le VHB est un probleme majeur puisque les 350 millions de porteurs chroniques existant ont un risque accru de developper une cirrhose ou un carcinome hepatocellulaire. Compte tenu du manque de systeme d'etude du VHB in vitro qui soit facile d'acces et pleinement satisfaisant, l'objectif etait d'ameliorer l'un de ceux qui utilisent des baculovirus VHB recombinants pour delivrer le genome VHB dans des cellules hepatocytaires. La pertinence de ce systeme pour realiser des tests phenotypiques et etudier le « fitness » des mutants resistants aux antiviraux a ensuite ete demontree. Enfin, l'utilisation de ces baculovirus VHB recombinants dans des cellules HepaRG a permis de mettre en evidence une reponse IFN efficace de l'hepatocyte suite a la synthese des proteines du VHB. Ceci constitue une donnee nouvelle dans l'etude des interactions virus/cellules puisque le VHB etait considere jusqu'a present comme un virus silencieux vis-a-vis de la reponse innee cellulaire. L'ensemble de ces resultats a des implications importantes dans la comprehension des mecanismes de persistance du VHB et le developpement de nouveaux modeles cellulaires d'infection.
Use of Gibberellic Acid to Increase the Salt Tolerance of Leaf Lettuce and Rocket Grown in a Floating System

Hydroponics need water of good quality to prepare a balanced nutrient solution that could allow plants to reach their maximum yield potential. The rising difficulties in finding water with good quality have led to the compelling necessity of identifying sustainable ways to use saline water, limiting its negative effect on crop yield and quality. The exogenous supplementation of plant growth regulators, such as gibberellic acid (GA3), can be effective in increasing plant growth and vigor, thus helping plants to better cope with salt stress. The aim of this study was to evaluate the feasibility to increase the salt tolerance of leaf lettuce and rocket grown in a floating system by adding GA3 (10−6 M) to mineral nutrient solutions (MNS) with increasing salinity (0, 10, and 20 mM NaCl). Leaf lettuce and rocket plants suffered a significant reduction of growth and yield, determined by the reduction of biomass, leaf number, and leaf area, even with moderate salt stress (10 mM NaCl). The supplementation of exogenous GA3 through the MNS allowed plants to substantially counterbalance salt stress by enhancing various morphological and physiological traits, such as biomass accumulation, leaf expansion, stomatal conductance and water and nitrogen use efficiency. The effects of salt stress and GA3 treatment varied according to the species, thus indicating that this interaction may improve salt tolerance by activating different adaptation systems.

Beyond ‘Liberals’ and ‘Conservatives’: Complexity in Ideology, Moral Intuitions, and Worldview among Swedish Voters

This research investigated the congruence between the ideologies of political parties and the ideological preferences (N = 1515), moral intuitions (N = 1048), and political values and worldviews (N = 1345) of diverse samples of Swedish adults who voted or intended to vote for the parties. Logistic regression analyses yielded support for a series of hypotheses about variations in ideology beyond the left–right division. With respect to social ideology, resistance to change and binding moral intuitions predicted stronger preference for a social democratic (vs. progressive) party on the left and weaker preference for a social liberal (vs. social conservative or liberal–conservative) party on the right. With respect to political values and broader worldviews, normativism and low acceptance of immigrants predicted the strongest preference for a nationalist party, while environmentalism predicted the strongest preference for a green party. The effects were generally strong and robust when we controlled for left–right self–placements, economic ideology, and demographic characteristics. These results show that personality variation in the ideological domain is not reducible to the simplistic contrast between ‘liberals’ and ‘conservatives’, which ignores differences between progressive and non–progressive leftists, economic and green progressives, social liberal and conservative rightists, and nationalist and non–nationalist conservatives.
Organizational Assets and Strategic Positioning in Telecommunication Industry in Kenya

The rapid development in the telecommunication industry has raised a question about the organizational assets and strategic positioning in a rapidly changing environment. The telecommunication industry is continuing to change and mounting a lot of pressure towards the fitness of organizational assets and strategic positioning. The demand for efficiency in the telecommunication industry has enabled exploration of organizational assets that guarantee desired strategic positioning. The fast changing environment has led the industry to focus on developing organizational assets which guarantee them future success in meeting the fast changing expectations and that which position them well in the dynamic market. The study was carried out in the four mobile and network operators licensed by Communication Authority of Kenya. These were Safaricom limited, Airtel Kenya, Orange Kenya and Equitel Kenya. Descriptive statistics such as mean scores, standard deviation, frequency distributions and percentages were used in this study. The study used Pearson Correlation to measure strength of linear relationship between variables. The research adopted multiple regression analysis in testing of variables. A Census method was used on strategic planning managers and C.E. O’s from 188 customer care centers from the four mobile and network operators. Primary data were collected using semi-structured questionnaires and secondary data were corrected using interview schedule. The questionnaires were administered to all Strategic planning Managers at customer care centers or C.E. O’s at headquarter offices for four companies in 47 counties. The findings on this objective revealed that organizational assets positively influence the strategic positioning of telecommunication industry in Kenya. The study concluded that assets components were all statistically significant to enhancing strategic positioning in the telecommunication industry. It is recommended that the strategic managers of the telecommunication industries should ensure the right use of assets. CAK and Ministry of ICT should make it a requirement that telecommunication industries should be submitting reports regularly of the assets they have.
IDENTIFIKASI PARASIT MALARIA PLASMODIUM FALCIPARUM PADA SEDIAAN DARAH DENGAN PENDEKATAN SUPPORT VECTOR MACHINE

Background: Identification of malaria is microscopic requiring special expertise and experience considerable health analyst. Factor errors that occur can be either an inability to recognize the parasite morphology and eyestrain factors in looking at morphology, this may impact the diagnosis of significant errors. Morphology of Plasmodium falciparum is divided into three major stages: trophozoites, Schizonts and Gametocyter. From the results of research in the field of health shows, Schizonts found in peripheral blood showed a state of severe infections so it is an indication for rapid treatment measures. This study aims to identify the three-stage form of Plasmodium falciparum malaria parasites in digital images of blood preparations which contain the parasite indicated. Method: Before conducting the identification process, the first step of the analysis procedure conducted in this study is to conduct the separation of the object by using the segmentation k-means clustering. The second step, to extract features of image data to be tested. Feature extraction is used as an insert in the system to be constructed in this study using color features. The final step is to identify three forms of identification test stage of the malaria parasite plasmodium falciparum using a Support Vector Machine (SVM) method multiclass ones against ones. Result: The results of this study using color as a characteristic feature of the input and identification using SVM can provide a success rate of 93.33% image data correctly. Keywords: malaria, Plasmodium falciparum Morphology, k-means clustering, SVM multiclass method ones against ones.
