Microwave- Assisted Synthesis of Nano/Micronized Zeolites from Natural Sources: Evaluation of Hydrogen Storage Capacities

This is a comparative study to investigate the hydrogen Storage ability of three zeolites; Zeolite-A, Faujasite-NaX and Analcime, prepared via microwave technique from refined kaolin. The paper addresses the effects of crystallite size, Si/Al, pore diameter and specific surface area on the hydrogen uptake capacity. X-Ray Fluorescence is used for rock chemical analysis, X-ray Diffraction for zeolite mineralogy, Scanning Electron Microscopy and Transmission Electron Microscopy for microstructure. Whereas, Electron Dispersion Analysis monitored the chemical microanalysis. Storing hydrogen is processed via Pressure, Composition and Temperature, using AMC PCI-HP 1200 equipment, meanwhile, BEL Sorb Max device (BEL JAPAN. INC) is used for specific surface area. Result indicates that, decreasing crystallite size has positive effects on both total pore volume and specific surface area, with a net result of higher hydrogen gravimetric capacities for all structures. At 77K and 22 bar, nanoFaujasite presents the highest hydrogen uptake of 2.25 wt%, whereas, nano Analcime hosts the least amounts of hydrogen of 0.74 wt%. Despite of the effect of zeolite particle size reduction on the surface area enlargement and high adsorption capacity, the limiting factor in hydrogen uptake into zeolite porous vicinities is the diameter of the pores and the blocking effects of their channels.
Studying international doctoral researchers: nexus analysis as a mode of inquiry

In this paper I argue how nexus analysis (Scollon & Scollon, 2004), as a holistic, qualitative mode of inquiry, can offer a fruitful activist research approach to study international doctoral researchers. To do this, I will introduce and explain the core concepts of nexus analysis and afterwards empirically demonstrate how nexus analysis can be done in practice by presenting a case study on international doctoral researchers in a particular nexus—at a Finnish university. The overall aim of this paper is to present nexus analysis as a viable alternative for those higher education researchers who want to study communication, interaction, and language-related challenges of international doctoral researchers from a bottom-up perspective and, in this way, potentially even challenge the existing decision-making practices.
Chemical structure of terrestrial humus materials formed from different vegetation characterized by solid-state 13C NMR with CP-MAS techniques.

SUMMARY Eleven samples of terrestrial humus from different vegetational backgrounds were examined with solid-state 13C NMR using cross-polarization and magic-angle spinning (CP-MAS). In addition, all the samples were run with a dipolar dephasing pulse sequence for non-quarternary carbon suppression (NQS). The humus samples all appeared to contain small amounts of aromatic substances and larger amounts of aliphatic compounds. Most of the samples contained considerable amounts of hydroxyl groups and acetals, which originate mainly from carbohydrates. No correlations were found between vegetational background and chemical structure.
Screening of Tuberous Sclerosis-Associated Neuropsychiatric Disorders in Korea Using the TAND Checklist

Purpose: The present study aimed to elucidate the clinical characteristics of children with tuberous sclerosis complex (TSC) in Korea using the Tuberous Sclerosis-Associated Neuropsychiatric Disorders (TAND) checklist to evaluate the comorbidities of neurocognitive and socioemotional problems in the Korean clinical setting. Methods: A survey based on the TAND checklist was administered to 58 children with TSC receiving treatment on an outpatient basis. Their medical records and test results were retrospectively examined. Results: At the time of TAND administration, 35 (64.8%) of the participants had focal epilepsy, three (5.6%) had generalized epilepsy, six (11.1%) had infantile spasms, and seven (13.0%) had Lennox–Gastaut syndrome. The most frequently reported behavioral problem was difficulty getting on with other people of similar age (38/58, 65.5%). Twenty patients had received previous diagnoses of psychiatric disorders, six of whom had received two or more concurrent diagnoses. A further evaluation after testing with the TAND checklist identified new psychiatric disorders in two patients. Among the 35 children who underwent a formal evaluation of intelligence, 27 (77.1%) exhibited intellectual disability. Of the school-aged patients, 65.6% (21/32) experienced difficulties with mathematics and 56.3% (18/32) with spelling. Difficulty dual-/multi-tasking (27/58, 46.6%) and low self-esteem (18, 31.0%) were the most frequent neuropsychological and psychosocial issues, respectively. Conclusion: Our findings indicate that patients with TSC tend to experience neurocognitive and socioemotional difficulties, and regular screening for TAND using the TAND checklist can be helpful for managing children with TSC in the clinical setting.
Predictors of outcomes following a brief Portuguese parental nutrition intervention

Early childhood is largely recognized as a critical period for shaping the child’s eating patterns.Although interventions studies that focus on first years of life are increasing, with positive impact,the moderators of treatment gains and the relative importance of each determinant of the changeprocess have been rarely explored. This study aimed to identify potential predictors of outcomesconcerning children’s healthy and unhealthy eating behaviors after a parental school-basedintervention. An intervention longitudinal study with repeated measures at baseline and afterparticipation in the Red Apple program was performed. Parents and children were recruited in publicand state-funded kindergartens near Lisbon, Portugal. A total of 44 parents of 3- to 6-year-old childrenagreed to participate in the study and 39 met the inclusion criteria. The Red Apple program includedfour parental group sessions about young children’s growth, nutritional guidelines, and positiveparental feeding strategies, and adult-child activities and newsletters delivered to caregivers. Dataregarding children’s dietary intake, food preferences, neophobia/neophilia, parental concerns aboutthe child’s weight, and self-efficacy in promoting healthy dietary patterns in children were collectedbefore (T1) and after (T2) the intervention. Higher parental concerns about weight and self-efficacyat T1 significantly predicted children’s healthy dietary intake at T2. The only significant contributionfor children’s unhealthy dietary intake at T2 was the previous consumption of those foods at T1.Interventions that focus on parental cognitive variables might effectively contribute to positive changes in children’s dietary intake. Findings also suggest that specific targets of children’s diet may pose unlike challenges that respond differently to the mechanisms of influence of the intervention.
Do SHRM Body of Competency and Knowledge behavioral competencies be beneficial for Hotel HR Managers? The Case of Cairo Five-Star Hotels

The Society of Human Resources Management (SHRM) Body of Competency and Knowledge is the basis for the SHRM credentials. The SHRM dictates the behavioral competencies and HR knowledge needed for effective job performance of managers. The current study tries to investigate the importance of the factors dictated by the model of competency (2017 edition) from the viewpoint of HR hotel managers working in five-star hotel chains in Cairo. The study uses a questionnaire design consisting of 33 HR manager. It investigates individual factors that potentially explain the new “competency model” that itemizes what a new HR manager really needs within the context of hotel sector. The study reveals significant benefits of behavioral competencies dictated by the SHRM model 2017 edition. A multiplicity of factors explains the role of these competencies in advancement. The findings indicate that HR managers advancement and success is explained by the model set of factors. The study findings suggest vital practical implications for the development of these competencies within the performance appraisal of HR managers.
Intuitive Judgments in Depression and the Role of Processing Fluency and Positive Valence: A Preregistered Replication Study

Background Recent preliminary evidence indicates that depression is associated with impaired intuitive information processing. The current study aimed at replicating these findings and to move one step further by exploring whether factors known as triggering intuition (positivity, processing fluency) also affect intuition in patients with depression. Method We pre-registered and tested five hypotheses using data from 35 patients with depression and 35 healthy controls who performed three versions of the Judgment of Semantic Coherence Task (JSCT, Bowers et al., 1990). This task operationalizes intuition as the inexplicable and sudden detection of semantic coherence. Results Results revealed that depressed patients and healthy controls did not differ in their general intuitive performance (Hypothesis 1). We further found that fluency did not significantly affect depressed patients’ coherence judgments (H2a) and that the assumed effect of fluency on coherence judgments was not moderated by depression (H2b). Finally, we found that triads positive in valence were more likely to be judged as coherent as compared to negative word triads in the depressed sample (H3a), but this influence of positive (vs. negative) valence on coherence judgments did not significantly differ between the two groups (H3b). Conclusion Overall the current study did not replicate findings from previous research regarding intuitive semantic coherence detection deficits in depression. However, our findings suggest that enhancing positivity in depressed patients may facilitate their ability to see meaning in their environment and to take intuitive decision.
Phytochemical screening and isolation of Eugenol from Syzygium aromaticum by gas chromatography

Tannins, phlobatannins, saponins, flavonoids, terpenoids, cardiac glycosides and alkaloids distribution and the isolation of euginol from Syzygium aromaticum, belongs to family Myrtaceae was examined. Qualitative analysis carried out on the plant shows that tannins, saponins, flavonoids, terpenoids and alkaloids are present in the plant. The gas chromatographic analysis of the compound was reported to have retention time of 7.93 minutes, whereas the mass spectroscopic analysis showed 164 as m/z value, which was in accordance with the molecular weight of euginol. The significance of the phytochemical constituents with the respect to the role of the plant in traditional medicine treatment is discussed.
Surface Tensions and Densities of Oxalic, Malonic, Succinic, Maleic, Malic, and cis-Pinonic Acids

The surface tensions and densities of aqueous solutions of oxalic, malonic, succinic, maleic, malic, and cis-pinonic acids were measured as a function of the acid mole fraction at 25 °C. These organic acids are typically found in atmospheric aerosols. The surface tensions were measured using the Wilhelmy plate method and were measured also as a function of temperature. The measurable mole fractions were limited by the solubilities of the acids at room temperature. All the acids lower the surface tension of pure water. cis-Pinonic acid lowers the surface tension most effectively. The measured surface tensions were fitted with equations covering the acid mole fraction range from zero to one and assuming a theoretical surface tension of pure, supercooled acids at room temperature. The measured densities were also fitted in a similar way. These equations can be used in model calculations of formation and growth of atmospheric particles.
Histological and Histometrical Features of the Mammary Gland in Immature and Lactating Local Breed Ewes (Ovis aries)

Twelve samples of mammary glands (6 immature and 6 lactating ewes) were used for this study. Specimens of glands were immediately dissected and fixed in 10% formalin sol. The specimens were processed according to paraffin technique, sectioned at 5-6µm and stained by hematoxylin and eosin, Masson's Trichrom stains. In both immature and lactating ewes the mammary glands were covered by skin. In immature ewes the mammary quarter was composed of few mammary lobes that separated by very thick inter lobar adipose tissue. The lactating quarter was composed of huge mammary lobes and lobules without adipose tissue. In immature the lobe was consisted of few small lobules that composed of few of mammary alveoli while the lactating lobes had large sizes lobules and each had large alveoli which lined by tall cuboidal cells and supported by fibrous tissue and myo epithelial cells. In both immature and lactating ewes, the gland and teat cisternae were showed many of mucosal folds which lined by pseudo stratified columnar epithelium and supported by fibrous connective tissue. The teat cisterna of both immature and lactating was composed three layers; mucosal cisterna, fibro muscular layer and skin. The teat canal was lined by pseudo stratified squamous epithelium and the sub epithelial connective tissue showed well developed venous sinus and fibro muscular. Statistical analysis was revealed significant differences between the values of all parameters of immature and lactating ewes. Apparent surface areas of the lobe in immature and lactating were 122143.063±23.21 µm2 & 992541.188±33.81 µm2 respectively. Surface areas of lobule in immature and lactating were 1042.938±21.02 µm2 & 91565.977±25.60 µm2 respectively. Surface areas of alveoli in immature and lactating were 994.238±11.39 µm2 & 4584.270±19.26 µm2 respectively. Epithelial heights of alveoli in immature and lactating were 10.290±1.01 µm & 23.012±2.81 µm respectively. Thickness of inter lobar tissue in immature and lactating ewes 677.393±23.67 µm and 361.401±10.86 µm respectively. Thickness of inter lobular connective tissue in immature and lactating were 112.969±±11.48 µm and 90.281±9.81 µm respectively.
Bulk crystal growth of hybrid perovskite material CH3NH3PbI3

Organic–inorganic hybrid perovskite materials have been receiving considerable attention due to their promising applications in many optoelectronic fields. However, some of the fundamental properties of perovskite materials are still disputed, because most of them are derived from a thin-film state. To comprehend the intrinsic characteristics in a single crystal, herein we report, for the first time, the bulk crystal growth of CH3NH3PbI3. Single crystals of tetragonal CH3NH3PbI3 with dimensions of 10 mm × 10 mm × 8 mm were grown by a temperature-lowering method in HI solution. Studies in to the refinement and orientations of the CH3NH3PbI3 single crystal structure were conducted based on a high quality crystal. The absorption edge of a CH3NH3PbI3 single crystal was located at about 836 nm, indicating that the band gap of CH3NH3PbI3 is approximately 1.48 eV, which is close to the theoretical results and smaller than those derived from polycrystalline and thin-films. CH3NH3PbI3 crystal exhibits a relatively wide absorption (from 250 nm to 800 nm) and a relatively good thermal stability.
AN ANALYSIS ON THE RELATIONSHIP BETWEEN DESTINATION IMAGE, SATISFACTION, AND ELECTRONIC WORD-OF-MOUTH OF DOMESTIC TRAVELERS TO SA DEC FLOWER VILLAGE

The study aims to analyze the relationship between destination image, satisfaction, and electronic word-of-mouth (EWOM) behavior of 215 domestic travelers. The author uses the method of analyzing and testing linear structural equation models (SEM). The study has conducted an evaluation of measurement and structural models. The results show that cognitive image directly affects affective image. Cognitive image and affective image directly impact tourist satisfaction and tourist satisfaction directly impacts electronic word-of-mouth behavior. In addition, this study also shows that cognitive image has an indirect effect on tourist satisfaction through affective image and affective image has indirect effects on electronic word-of-mouth behavior through tourist satisfaction.
RMP 2 : A Differentiable Policy Class for Robotic Systems with Control-Theoretic Guarantees

We consider the problem of achieving safe robot learning through learning on an inherently safe policy class. The safe policy class is inspired by RMPﬂow, a framework for robot policy design that provides control-theoretic guarantees. We re-examine the computational structure of RMPﬂow, and propose a more efﬁcient alternate algorithm, called RMP 2 (RMPﬂow Reactive Motion Policy), that uses modern automatic differentiation tools (such as TensorFlow and PyTorch) to compute the RMPﬂow policy. Our reduction retains the strengths of RMPﬂow while bringing in advantages from automatic differentiation, including 1) support of general directed acyclic graph (DAG) transformation structures; 2) easy programming interfaces to designing complex transformations; 3) improved computational efﬁciency; 4) end-to-end differentiability for policy learning. Because of these features, RMP 2 can be treated as a differentiable policy class for learning with control-theoretic guarantees, which is suitable for safe exploration and encoding domain knowledge. Our experiment gives a proof-of-concept demonstration on a reinforcement learning problem for goal reaching in a cluttered space.
FINANCIAL DEVELOPMENT IN NIGERIA: THE ROLE OF REMITTANCES

Given the increasing inflow of remittances to Nigeria, it is imperative to assess whether they have impact on financial development in Nigeria or not. So, the study examined the impact of remittances on financial development in Nigeria. The study used two indicators as proxies for financial development which include: money supply and market capitalization. The study used secondary data which were sourced from the Central Bank of Nigeria Statistical Bulletin and World Bank’s World Development Indicators. Owing to the fact that the data used are stationary at different orders and are co-integrated, the study employed AutoRegressive Distributed Lag Model (ARDL) to investigate the impact of remittances on financial development. The results from the regression indicate generally that remittances have impact on financial development. It was found in the result that remittances have positive impact on money supply in Nigeria. It however, exerts no-impact on market capitalization in Nigeria.
Long-term outcomes of therapeutic penetrating keratoplasty versus elective penetrating keratoplasty in a tertiary care center in Israel

Purpose: The purpose of the study was to compare the results of therapeutic keratoplasty (TK) with those of elective penetrating keratoplasty (PK). Materials and Methods: A retrospective case–control institutional study design was used. The medical records of patients that underwent full thickness or lamellar keratoplasty between 1/2008 and 12/2015 in Rabin Medical Center (Petach Tikva, Israel) were evaluated. The study group included eyes which had TK. The control group included eyes which had PK during the study period. Outcome measures included demographic details, indication for TK, follow-up time, intraoperative and postoperative complications, the need for additional surgeries, best-corrected visual acuity (BCVA), and the presence of a clear graft at last documented visit. Results: Out of 1094 keratoplasties performed in the study period, 17 (1.55%) were therapeutic penetrating keratoplasties. The control group consisted of 240 consecutive penetrating keratoplasties. Indications for TK were severe infections (14 eyes, 82.4%) and sterile perforations (3 eyes, 17.6%). In 9/17 (52.9%) TK eyes, there was a preexisting penetrating corneal graft. Twelve corneas were perforated at the time of surgery (12/17–70.6%). Eight infected corneas were perforated at the time of surgery (8/14–57.1%). No intraoperative complications were noted for any patient. There were no differences in age and follow-up period between the groups. Primary failure rates were higher in the study group (29.4% vs. 14.6%, P = 0.15) and fewer eyes in the study group had clear cornea at last documented visit (66.7% vs. 77.5%, P = 0.48). Persistent epithelial defects and glaucoma were more common in the study group (47.1% vs. 5.0%, P < 0.0001 and 47.1% vs. 17.1%, P = 0.006, respectively), as were the need for additional surgeries (64.7% vs. 18.7%, P = 0.0001). BCVA on last visit was worse in the study group with only 11.8% having 6/45 visual acuity or better versus 41.7% in the control group (P = 0.02). Conclusions: Results of TK are inferior to those of elective PK. However, the primary purposes of TK, namely, saving the globe and maintaining useful visual acuity can be achieved in most cases. The increased complication rate and the probable need for additional procedures should be discussed with the patient.
Effect of Product Package on Brand Involvement in Consumer Goods Markets of Lagos State Nigeria

The objective of this study is to investigate the relationship between package design and customer involvement in brand using the Food and Beverages Industry of Lagos State, Nigeria. The descriptive survey design was adopted for the study. 2374 consumers of packaged food products were proportionally sampled across the 20 local government areas of Lagos State. Questionnaire was the main instrument for data collection rated on a 6 – point Likert scale. Data were analysed using the descriptive statistical techniques of Pearson Product moment correlation (r) and Simple Regression Analysis. The results of the study revealed that package design significantly influence customer involvement in a brand (p < 0.05, R = 0.501; R 2 = 0.251) and this can be achieved through effective choice of label information, logo, brand size and shape which are all ingredients and attributes of good package design for a brand. It was recommended that aesthetic components of the product package should be soothing for the eyes of the consumers to enhance good point – of – purchase appearance.
