Rice Husk Ash as a Potential Source Material for Geopolymer Concrete: A Review

Concrete is the most versatile, durable and reliable construction material on the planet. But sustainability becomes the major concern as the conventional concrete is not eco-friendly due the large carbon footprint of Ordinary Portland Cement (OPC) industries. Efforts are needed to develop an eco-friendly material with minimal environmental damage. A concrete with complete replacement of OPC by pozzolanic materials like fly-ash, Rice Husk Ash (RHA), Ground Granulated Blast-furnace Slag (GGBS) etc. having a polymeric binder is called Geopolymer concrete (GPC). In Geopolymer concrete, most of the research work has been focused on fly ash based binders. However, the RHA has the potential to be used as a source material in Geopolymer concrete as the RHA is a pozzolanic material containing about 85-90% of silicon dioxide (SiO2). This paper briefly reviews the work carried out by various researchers & scientists on RHA based Geopolymer concrete as well as focuses on sustainable utilization and potential benefits of using RHA in the field of Geopolymer concrete.
Unusual silicate mineralization in fumarolic sublimates of the Tolbachik volcano, Kamchatka, Russia – Part 2: Tectosilicates

Abstract. This second of two companion articles devoted to silicate mineralization in fumaroles of the Tolbachik volcano (Kamchatka, Russia) reports data on chemistry, crystal chemistry and occurrence of tectosilicates: sanidine, anorthoclase, ferrisanidine, albite, anorthite, barium feldspar, leucite, nepheline, kalsilite, sodalite and hauyne. Chemical and genetic features of fumarolic silicates are also summarized and discussed. These minerals are typically enriched with “ore” elements (As, Cu, Zn, Sn, Mo, W). Significant admixture of As5+ (up to 36 wt % As2O5 in sanidine) substituting Si is the most characteristic. Hauyne contains up to 4.2 wt % MoO3 and up to 1.7 wt % WO3 . All studied silicates are hydrogen-free, including mica and amphiboles which are F-rich. Iron-bearing minerals contain only Fe3+ due to strongly oxidizing formation conditions. In Tolbachik fumaroles, silicates were formed in the temperature range 500–800 ∘ C as a result of direct deposition from the gas phase (as volcanic sublimates) or gas–rock interactions. The zonation in distribution of major silicate minerals observed in a vertical section of the Arsenatnaya fumarole, from deep (the hottest) to upper parts is diopside + forsterite + enstatite + andradite → diopside → fluorophlogopite + diopside → sanidine + fluorophlogopite → sanidine. This is in agreement with volatilities of major species-defining metals in volcanic gases. From a crystal-chemical viewpoint, this series corresponds to the following sequence of crystallization of minerals with temperature decrease: nesosilicates → inosilicates → phyllosilicates → tectosilicates.
3D Printed Soft Robot Gripper with Closed-Loop Control

This project aims to build up a soft robotic gripper that mimics human hands and design a closedloop control system. A soft gripper model is established with Finite Element Method (FEM) to describe the relation between air pressure input and gripper deformation. The best soft gripper dimensions are selected according to the FEM model and the gripper is then fabricated with Fused Deposition Modeling (FDM) 3D printing method. Closed-loop angle control before the soft gripper touches the object is used to ensure a precise grasp. A camera sensor is used for the acquisition of the bending angle and a pressure regulator is applied to supply the air pressure. A closed-loop experiment platform is built based on a proportional-integral (PI) controller to realize the precise deformation control of the soft gripper. Finally, the grasp of some soft or brittle objects using the soft gripper is performed as a demonstration.
Comparison of Basic Internal and External Egg Quality Traits of Brown and White Egg-laying Hens in Relationship to their Age

This study was focused on the comparison of the brown and white eggs from two laying hybrids. The objective was to assess basic quality traits of eggs from both groups of hens and compare them. The impact of how age influences the technological value of eggs was also observed. The most important correlations were calculated. Products of Czech original genetic programmes, Dominant Brown D 102 and Dominant Leghorn D 229 hens were included. A total of 1500 eggs were analysed. The egg collection was made for three consecutive days when the hens were at the 28, 35 and 59 weeks of age. The results showed that eggshell weight, yolk weight and yolk share increased with the age, while egg shape index, yolk index and albumen share decreased in both hybrids. Eggshell weight and share fluctuated with the age in both hybrids. Other traits differed within the hybrids. Interactions between age and hybrid were non-significant (P > 0.05) only in eggshell and yolk weight. The heaviest eggs were from 59-week-old Dominant Brown D 102 hens (68.89 g) and the lightest eggs were from 28-week-old Dominant Leghorn D 229 hens (57.76 g). Highly significant (P ≤ 0.001) positive correlations were found between egg weight and all individual egg components weights and between eggshell weight and yolk and albumen weight and eggshell thickness in both laying hybrids.

Motivational factors on purchase intention of in-game hero skins in MOBA games

Multiplayer online battle arena (MOBA) games are increasing in popularity. These MOBA games are known to provide players with in-game purchasable add-ons. However, to date the impact of such in-game purchases, particularly hero skins, on player's motivation is unexplored. We use self-determination theory to develop a survey for measuring players' motivation when purchasing in-game hero skins of Defense of the Ancient 2 and League of Legends. 133 participants were surveyed on multiple factors related to intrinsic and extrinsic motivation, including, competence, autonomy, relatedness, money, rewards, praise, reputation and purchase intention. Results show that competence, praise, and rewards can independently predict the purchase intention and when combining competence, praise and rewards, only competence and praise can influence purchase intention. Thus, our study highlights that player’s competence and need for praise especially influences their intent to purchase in-game hero skins. While further validation is warranted, the survey presented in this thesis can assist to contribute to measuring the motivation on in-game hero skins purchases.
Cyclic Voltammetry and Oxidation Rate Studies of Ferrous Gluconate Complex Solutions for Preparation of Chitosan-Tripolyphosphate Microparticles

A proper understanding of the properties of iron could increase the effectiveness of programmes for alleviating iron deficiency. Recently, encapsulation has been considered an appropriate method for protecting iron from injurious reactions. However, several events may occur during encapsulation processes, including changes in the iron’s oxidation state. Oxidation of ferrous iron is not desirable since the intestines can only absorb iron in the ferrous form. In this study, a cyclic voltammetry method was applied to investigate the likelihood of ferrous gluconate oxidation for the preparation of chitosan-tripolyphosphate microparticles. Then, the electrochemical properties of ferrous gluconate were confirmed experimentally. The oxidation rate of ferrous gluconate is also discussed in this paper. All the experimental solutions were formulated in detail to produce conditions similar to those of microparticle production. Cyclic voltammetry analysis was conducted using a configuration of three electrodes connected to an electrochemical analyser. Graphite, platinum wire, and Ag/AgCl were employed as the auxiliary, working, and reference electrodes, respectively. The cyclic voltammetry results show that the observed potential for each anodic peak shifted negatively in the presence of chitosan and sodium tripolyphosphate. Moreover, the rate of ferrous oxidation tended to increase during 75 min of experiments due to the presence of chitosan and sodium tripolyphosphate. These behaviours indicate the transformation of ferrous iron to ferric iron during iron microparticle preparation. Furthermore, these findings suggest that spray drying is a preferable method to minimise the oxidation reaction.
Quantitative estimation of complex phosphate - solubilization by immobilized or free Azospirillum Lipoferum (H3) as vital vaccine in Pikovskaya broth (PVK) medium

Azospirillum species were collected from the rhizosphere and free soil of different plants in Al-Jabal El- Akhdar region. The isolates were identified according to biochemical activities. Isolate (H3) which showed the higher solubilization efficiency (SE) on Pikovskaya medium (PVK) containing insoluble phosphate (inorganic phosphate) Ca3(po4)2 Isolate (H3) was identified as Azospirillum lipoferum (H3), which used as an inoculum as free cell suspension or as alginate formulation. Phosphate solubilization was measured by A.lipoferum (H3) as free or alginate immobilized cells in (PVK) liquid medium and recording the pH of the medium at the same time. The results showed in the phosphorus content by immobilized bacteria in liquid (PVK) broth medium from 2nd day of incubation (2.48 µg/ ml) to 10th day (3.70 µg/ ml) and the free bacteria from 2nd day (8.81 µg/ ml) to 10th day (4.49 µg/ ml). pH of the liquid (PVK) broth medium was recorded from 2nd day to 10th day after incubation which decreased by immobilized A.lipoferum (H3) from 7.00 pH to 4.47 on the 10th day and by the free A.lipoferum (H3) to 6.00, which improved the production of organic acids from sugars which was response of decreasing the pH of the medium. This present study contribute to make agriculture more productive with less harm to the environment and for developing countries where the use of fertilizers is costly, and to encourage of using the biofertilizers ‘plant growth promoting rhizobacteria’ (PGPR) instead of the chemical fertilizers to enhance the plant growth which is the main goal to increase the food production in a healthy way.
Effect of Marketing Practices on Credit Card Usage: The Mediating Role of Consumer Attitudes

Credit card use has gained popularity throughout the world. Banks introduce the credit card service as a way of improving their revenue streams. However, in Kenya, the rate of growth in usage has rather been slow. This research surveyed credit card holders in Nairobi, Kenya with a view to investigate the effect of marketing practices on credit usage and whether consumer attitudes had a mediating effect between the two factors. A cross-sectional survey was conducted by administering a structured questionnaire to 380 respondents. The study established that marketing practices affect credit card usage and that consumer attitudes did not significantly mediate the relationship between marketing practices and credit card usage. This paper makes a valuable contribution to managerial practice by showing how the elements of the extended marketing mix affect credit card usage. Thus it serves to inform the implementation of marketing strategy in banks by guiding on which aspects of marketing should be emphasised so as to increase credit card usage.
EFFECT OF ARGININE AND SELENIUM WITH VITAMINE E ON PLACENTA OF IRAQI EWES

The objective of the study to demonstrated the effect of arginine and selenium with Vit E or both on histological picture of ovine placenta in Iraqi ewes. The Study was conducted on 24 pregnant Iraqi Ewes aged between 2-4 years and weight of 40-50 Kg, presented in Anbar during the period from 20 of April to 10 of October 2018. The animals were divided into four equal groups. Placentomes were taken within 6 hours post-partum from 4 ewes of each group. The Placentomes were taken manually per vagina fallowing parturition. It is collected from the center of the pregnant horn. Directly after collection the samples were fixed in 10 % buffered neutral formalin for 48 hours. The specimen of the tissue were dehydrated in a graded series of alcohol, then cleared with xylol and embedded in paraffin. Histological section were done with microtome using 4 μm thicknesses and then stained with hematoxylin and eosin. Each slide was examined under light microscope with low and high power magnification. Histological examantion of sheep treated with arginine (T1)showed vascular changes includes vasodilation of blood vessels and lymph vessels. There was Congestion blood vessels and a hypertrophy of endothelial Cells. There were a mononuclear Cell infiltrations and hypertrophy in the Connective tissue of the maternal side. while sheep that treated with selenium plus vitamin E(T2) showed a high vascular change with presence of hemosiderin pigment. There is an enlargement of trophoblast. It is also noted that is few binucleated cell infiltration were seen. Histological picture of the third group (T3) treated with a combination of arginine with Se plus vitamin E showed vasodilation in blood vessels. There is an endothelial cell hypertrophy and trophoblastic hyperplasia. There is also extracellularmatrix odema. These changes observed might be resulted from the treatment with the combination (arginine , Se + Vit E). Histologic section of Placentomes from ewes treated with normal saline (T4Control) (Figure-4) showed vascular changes, odema hyperemia and hemorrhage. There is a vasodilation and congestion in the blood vessels. There is a great hyperplasiaof the trophoblast. Few number of binucleated cell were seen in the trophoblast. It was concluded from this study that arginine , Selenium and vitamin E increase placenta blood flow and increase immunity for both maternal and fetal side

Multi-Dimensions Motivational Factors in Autonomous Driving

The autonomous cars are predicted to be an optimized driver and would only have one motivation that is purely based on mobility. On the other hand, the human drivers might have more than one motivational factor when they are driving the car. Unexpected motivational factors or driving goals could suddenly occur during the driving and would usually change the way one is driving. In autonomous driving, where human has no longer control over the driving decision, the consequence of sudden occurrence of motivational factors would be the temptation to take over the automation or else one will experience mental discomfort. In this position paper, we are trying to set up an experiment to investigate how the unexpected motivational factors could tempt the driver to take over the automation from the autonomous car.
The Impact of Artificial Intelligence on Security: a Dual Perspective

This paper analyses the impact of Artificial Intelligence (AI) on security processes. Through the analysis of risk maps (a risk analysis tool), we highlight two opposing views: Beneficial AI and Malicious AI. Beneficial AI focuses on improving security, covering capabilities such as security design and testing assistance, system security monitoring, and decision making upon cyber-attacks. Malicious AI focuses on lowering security, covering capabilities such assistance for attack undetectability, or for attack decision making. While we recall means of attacks ranging from enhanced cyber-attacks to social-engineering, we also describe ways of integrating AI in companies and products’ life cycle and reflections about ethics in AI. We then analyze how impacted IoT systems may be considering the relationships between connected objects and AI models and their use cases. Finally, we conclude with two recommendations: revisiting risk frameworks to integrate AI, and providing recommendations for an ethical approach to AI research.

In this article are presented palynological characteristics of five plants found in different areas in Albania. For each plant are describe the shape of pollen grains, number of furrows and their pores, characteristics of exine and intine. From the study resulted that pollen grains of Epilobium angustifolium were 3 porate, rare 4 porate; pollen grains of Echinops ritro and Tragopogon balcanicus were 3 colporate; pollen grains of Asyneuma limonifolium were 4-5 porate; pollen grains of Juniperus oxycedrus were inaperturate. The layer of exine in Epilobium angustifolium was smooth, rare accompained by small granules (granulate); exine surface in Echinops ritro was microechinate-reticulate; in Tragopogon balcanicus, exine surface was echinolophate or fenestrate; exine surface in Asyneuma limonifolium was perforate and plycate; in Juniperus oxycedrus was covered with small granules scattered without any order.
Structural proteins of plasmolemma of the jejunum absorbing enterocytes of cattle fetus in early fetal period

The data on the concentration of structural proteins of plasmolemma of the absorption enterocytes of the cattle fetus in the early fetal period are presented. Changes in the protein composition of the apical and basolateral membranes of enterocytes are manifested, characterized not only by changes in their ratio within different cell domains, but also by the dynamic redistribution of the number of different fractions of polypeptides between the poles of these cells. Analysis of the results of electrophoresis of apical membranes of the cattle fetus enterocytes in the early fetal period indicates a decrease in the content of low molecular weight protein fractions and an increase in high molecular weight. In the apical membranes of enterocytes of two-month-old cattle fetus, 25 protein fractions with a molecular weight of 9.6 to 205 kDa were detected. In the basolateral membranes revealed 23 protein fractions with a molecular weight of 9.6 to 120 kDa. High molecular weight fractions of polypeptides with molecular weights of 250 kDa and 300 kDa appear from the age of three months of embryos of calves. In the basolateral membranes of enterocytes, there is a slight decrease in the content of low molecular weight protein fractions, and from the four months of age of cattle fetus, high molecular weight fractions of polypeptides with molecular weights of 22.5 kDa and 155 kDa appear, which are absent in basolateral membranes of enterocytes. Two-month-old fetus lack proteins with a molecular weight of 19 kDa, 24 kDa, and 66 kDa in the apical part, whereas proteins with a mass of 22.5 kDa, 155 kDa, 170–185 kDa, and 205 kDa are absent on the basolateral membrane. In the apical membrane of enterocytes significantly more proteins with a low molecular weight of 9.6-14.2 kDa (1.56 times; P ≤ 0.001), whereas in the basolateral membrane a significantly higher concentration of proteins with a molecular weight of 15.5 kDa (2.06 times; P ≤ 0.001) and 17 kDa (3.62 times; P ≤ 0.001).
Adaptations métaboliques et hormonales au cours de l'exercice

poids corporel et consomment 30 à 35 % de l’oxygène au repos. Leur mise en jeu au cours de l’exercice s’accompagne de modifications physiologiques complexes devant répondre à un double objectif métabolique : satisfaire les besoins accrus générés par la contraction musculaire et assurer l’homéostasie énergétique, notamment glucidique, du reste de l’organisme et, tout particulièrement, du système nerveux central. Ainsi, aux adaptations cardiovasculaires et respiratoires, assurant essentiellement une fonction de transport et d’apport en oxygène, s’associent des adaptations métaboliques régulées par un système neurohormonal complexe. L’exploration de l’aptitude physique, largement répandue chez le sujet sain comme chez le malade, s’intéresse principalement aux adaptations cardiorespiratoires et méconnaît souvent les adaptations métaboliques et hormonales. Ces dernières sont pourtant primordiales et conditionnent en grande partie les performances musculaires et la récupération. Elles peuvent être altérées dans de nombreuses pathologies mais également chez le sujet sédentaire, et varient considérablement selon la nature de l’exercice (intensité, durée, type). Cette mise au point s’intéresse aux principales caractéristiques des adaptations métaboliques et neurohormonales au cours de l’activité physique. Après un rappel du métabolisme énergétique musculaire et des contraintes métaboliques générées par l’exercice, nous envisagerons les principaux mécanismes neurohormonaux mis en jeu en réponse à ces contraintes. Enfin, les effets de l’entraînement et du déconditionnement musculaire sur les adaptations métaboliques et hormonales à l’effort seront abordés. M I S E A U P O I N T
