Diverse Synthesis and Characterization Techniques of Nanoparticles

Nanoparticles are small particles that range from 1 to 100 nm in size, exhibit several physical and chemical features. An understanding of nanoparticles would reveal great qualities and potential applications that would aid the diversification of thin film technologies. The synthesis methods employed like top-down, bottom-up, chemical, biological, and mechanical processes have great influence on the properties exhibited by such nanomaterials. This review covers an insight into the knowledge of nanoparticles, their classifications, parameters affecting their efficient performance, synthesis and characterization techniques of nanoparticles. Nanoparticles are also characterized to obtain their morphological, structural, optical, elemental, size, and physiochemical features. The potential applications of nanoparticles have not been left undiscussed.
Feeding Preference of Cutlassfish (Trichiurus lepturus Linnaeus) in Coastal Waters of Gunungkidul, Yogyakarta

Research on cutlassfish’s diet has been carried out in several areas, but similar research does not exist or still rarely found in Gunungkidul. The aim of this study is to determine the overall composition of the cutlassfish's food, the most dominant type of food and cutlassfish's growth pattern. Methods including random sampling in the field, measurement of length and weight and identification of food types using stomach analysis method and proximate analysis on both cutlassfish’s muscle and diet. The results of the study then analyzed using the formula by Walpole (1992), length-weight relationship formula according to Le Cren (1951) followed by determining the value of b with the t-test at confidence interval of 96% and condition factor. Food composition and preferences were calculated using numerical and volumetric methods to find the IP ( Index of Preponderance ) and IRI ( Index Relative Importance ) values. Composition based on types of food is dominated by fish at 89% with Engraulidae as the main group with total percentage of IP 45.58 and IRI 76.47, respectively. Proximate analysis values indicate low levels of protein (with highest value of 23.82%) and high-moisture content (with highest value of 71.98%) caused by cold temperatures during storage. The regression showed that cutlassfish have an allometric positive growth pattern. The results revealed that the food is sufficient for the growth of cutlassfish ( Trichiurus lepturus ).
Mechanistic Study of the Effects of Magnesia Reactivity on Setting and Hardening of Basic Magnesium Sulfate Cement

Basic magnesium sulfate (BMS) cement was prepared by magnesia with different reactivities derived from calcination of basic magnesium carbonate at 600 to 1000°C. The effects of reactivity of magnesia on the setting time and compressive strength of BMS cement was investigated. Furthermore, XRD, SEM, MIP, hydration heat evolution and the pore solution composition were used to analyze the action mechanism of magnesia reactivity. The results show that the main strength phase of 5Mg(OH)2·MgSO4·7H2O (5·1·7 phase) was formed in BMS cement prepared by magnesia with calcination temperature higher than 600°C. The magnesia with a high BET surface area and low crystallite dimension showed a high adsorption capacity for citrate ions in magnesium sulfate solution, decreasing their concentration in the pore solution. By acting as a soft template for 5·1·7 phase formation, the decrease in citrate ions resulted in a low amount of 5·1·7 phase, forming Mg(OH)2 instead, leading to a low-strength BMS cement.
State and self-regulation for better governance: an implication of collibration

Purpose The purpose of this study is to study the evolution of French corporate governance law in light of collibration approach and bring statistical evidence from French Companies Executive Compensation practices. Design/methodology/approach The study has used mixed methods. In the first part, the authors analyzed the French laws in the light of collibration. In the second part of the study, the authors used unbalanced panel data to test the hypotheses related to executive remuneration based on the theoretical underpinning of collibration. Data for 173 firms listed in the Euronext Paris Index is collected from the Bloomberg database. Seemingly unrelated regression (SUR) analysis is performed to investigate the impact of collibration on the governance disclosure of French-listed firms. Findings SUR results indicate that board size plays a significant role in the governance disclosure before collibration. However, the collibration model is found to be more effective in ensuring the desired level of governance disclosure. Under the collibration approach, executive remuneration, frequency of board meetings, executive directors in the compensation committee and independent directors play a significant role in governance disclosure. Board size, however, does not have a substantial impact on governance disclosure after the adoption of collibration mechanism. Research limitations/implications Results provided by this study can allow regulators to improve corporate disclosure regime in France, which could play a vital role in safeguarding the interest of stakeholder. Originality/value The authors study the impact of collibration on the extent of governance disclosure in the context of France. Empirical evidence on the implication of collibration as governance mechanisms to enhance stakeholder confidence is rare and allows this study to make a unique contribution to the governance literature.
Nexo: Una herramienta para la visualización y análisis de indicadores QoS y QoE móviles

With the growth in the usage of mobile technologies, it is increasingly important for both application developers and service providers to provide optimum quality to their users. Currently, there are several tools that allow to visualize the different quality indicators that impact the user experience; However, the concepts of Quality of Service (QoS) and Quality of Experience (QoE) are often studied separately, which makes the complete analysis of quality a difficult task. That is why, in this project, Nexo is presented: a tool that allows quality indicators (both QoS and QoE) to be collected in mobile applications, as well as to classify and visualize them graphically in order to establish links between them. To verify the correct operation of Nexo, a case study in which various QoS and QoE indicators were collected from a real application (AntennaPod) was carried out and, later, those indicators were analyzed by the generation of different graphics with the tool. Through this case study, the relationship between quality of service and quality of user experience could be validated.
Measuring crack-type damage features in thin-walled composite beams using de-noising and a 2D continuous wavelet transform of mode shapes

A new method is described, allowing to locate and also measure the length and orientation of crack-type damage features in thin-walled composite beams (TWCB), a capability not previously reported. The method is based on a modal-analysis technique and is shown to work on a hollow composite beam, going beyond previous work limited to simple beams and plates. The method is shown to be capable to function down to signal-to-noise ratios (SNR) of about 15, corresponding to far noisier conditions than in previous work. This capability is achieved by a combination of wavelet de-noising and the use of a 2D Continuous Wavelet Transform (CWT), applied to two modal analysis metrics, COMAC and Mode Shape Differences (MSD). The length and orientation of the crack can be determined accurately using a 2D curve fitting approach. Using either COMAC or MSD produces reliable results, but MSD is found to be somewhat more noise-tolerant. The new method is believed to be useful for the measurement of damage features in a variety of thin-walled composite beams such as aircraft wings and wind turbine blades, among others.
Studies on Microcapsules. II. Preparation of Polyphthalamide Microcapsules

Polyphthalamide microcapsules were prepared by the interfacial polycondensation reactions between each of 1, 6-hexamethylenediamine and diethylenediamine and each of o-, m-, and p-phthaloyl dichlorides under various conditions. The size and size distribution of the microcapsules formed were determined and the factors affecting them were of studied. Favorable conditions were suggested to obtain the microcapsules of uniform size in a high yield.
Technology-supported reflection : towards bridging the gap between theory and practice in teacher education

The ability to convert theoretical knowledge into practical behavior is a common obstacle facing newly graduated employees in most professions. To overcome this obstacle, educational institutes are offering some kind of field training courses that allow their students to practice and gain experience in a real professional situation. In some professional training institutes, such as teacher education and nursing institutes, these courses are usually mandatory requirements for completing the program. The goal of the field training is to give the students the opportunity to apply their theoretical knowledge, under experienced supervision, in a real professional context. In other words, field training supports the period of transition between the initial training of prospective teachers and their entry into professional life as fully qualified teachers (European Commission, 2002). In teacher education, many educators, for instance Buckingham (2005), Smith (2000), Stigler and Hiebert (1999) and Schon (1987) warn about a gap between the theoretical knowledge that is acquired from the educational program and the practical skills that are required at the schools in this transition period. This gap is also found in the teacher education programs in Kuwait (Al Deeb, 1997). The poor performance of the field training in developing prospective teachers’ competences is presented as an important factor that is causing this gap in teacher education in Kuwait (Hasan, 2001). Improving the performance of the field training in these programs could lead to reducing the gap between theory and practice. This study attempts to improve the field training in the teacher education programs in Kuwait through the facilitation of the reflective practice approach among prospective teachers in these programs.
New trickling filter applications in the U.S.A.

After falling in disfavor in the U.S. in the 1970s, trickling filters are now reappearing in new applications. The Trickling Filter/Solids Contact (TF/SC) process uses physical and biological flocculation features to transform the poor quality of the trickling filter effluent into an effluent equal to the best activated sludge system. Over 50 TF/SC plants have been built since the process was introduced in 1979. The recent development (1988) of the Biofilm-Controlled Nitrifying Trickling Filter (BCNTF) has permitted higher rate operation and rendered the process less costly than the activated sludge system for nitrification. Three BCNTF projects are now underway in the U.S.
Gemcitabine, oxaliplatin and dexamethasone (GemDOx) as salvage therapy for relapsed or refractory diffuse large B-cell lymphoma and peripheral T-cell lymphoma

Background Outcomes of relapsed or refractory diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma (PTCL) remain poor. The objective of this study was to evaluate the efficacy and safety of gemcitabine, oxaliplatin and dexamethasone (GemDOx) with or without rituximab as salvage therapy in patients with relapsed or refractory DLBCL and PTCL. Materials and Methods: We retrospectively reviewed patients with relapsed or refractory DLBCL and PTCL receiving GemDOx as salvage therapy between Jul 1, 2011, and Aug 31, 2017. Results: Thirty-three (57.9%) patients with relapsed or refractory DLBCL and 24 (42.1%) with PTCL were included in this study. The median age was 57 years (inter-quartile range 46-67). The overall response rate (ORR) in DLBCL was 48.5% with 27.3% of complete remission (CR), and the 2-year progression-free survival (PFS) and 2-year overall survival (OS) was 21% and 44%. In patients with PTCL, ORR was 50.0% with CR rate of 29.2%; the 2-year PFS and 2-year OS was 28% and 49%, respectively. Common grade 3-4 hematological adverse events were thrombocytopenia (26.3%), anemia (15.7%) and neutropenia (15.7%). Conclusion: With acceptable efficacy and good tolerability, GemDOx might be a new therapeutic option for relapsed or refractory DLBCL and PTCL.
Algorithmic Fairness: Choices, Assumptions, and Definitions

A recent wave of research has attempted to define fairness quantitatively. In particular, this work has explored what fairness might mean in the context of decisions based on the predictions of statistical and machine learning models. The rapid growth of this new field has led to wildly inconsistent motivations, terminology, and notation, presenting a serious challenge for cataloging and comparing definitions. This article attempts to bring much-needed order. First, we explicate the various choices and assumptions made—often implicitly—to justify the use of prediction-based decision-making. Next, we show how such choices and assumptions can raise fairness concerns and we present a notationally consistent catalog of fairness definitions from the literature. In doing so, we offer a concise reference for thinking through the choices, assumptions, and fairness considerations of prediction-based decision-making.
A Qualitative Method Proposal for the Study of Strategy as Practice

Purpose: recently, the strategy as practice approach has sought to overcome the micro/macro dichotomy existing in its literature, as well as to better integrate the dimensions of praxis, practice and practitioner. To fill this gap, the aim of the paper is to discuss potential methods to guide empirical studies of strategy as practice (SAP). Method: the paper proposes a method based on an extensive literature review. Phenomenology, grounded theory, ethnography, and narratives are discussed, and their components are presented in the context of strategy as practice studies. Results: the presented method articulates four approaches. Phenomenology is used to enhance the understanding of strategist experiences. Grounded theory is considered a method to develop theories about the studied phenomenon. Ethnography is used to contextualize the daily practices of strategists. Narratives are the path to access the stories of the strategists. Conclusion: the proposed method may be useful to overcome micro/macro dichotomy existing in strategy as practice literature and to integrate praxis, practice and practitioner dimensions.
Modélisation de l'adsorption dans les matériaux nanoporeux flexibles

Les materiaux hybrides organiques-inorganiques presentent des proprietes d'adsorption et de flexibilite inedites. Le couplage entre ces deux aspects joue un role important dans le comportement de ces materiaux soumis a l'adsorption d'un fluide. Cette these a pour but de developper des methodes adaptees a l'etude de ces systemes physico-chimiques.

Pregabalin is a γ-amino butyric acid analogue drug that is used in fibromyalgia, neuropathic pain associated with diabetic peripheral neuropathy, spinal cord injury, and postherpetic neuralgia. Symptoms reported in association with pregabalin withdrawal include insomnia, gastrointestinal distress, tachycardia, and headache. This case report describes a 68-year-old patient who developed delirium after experiencing pregabalin withdrawal. Clinicians should be aware of the possibility of pregabalin withdrawal delirium.
C&O charging: a hybrid wireless charging method for the mine internet of things

Most nodes of Mine Internet of Things (Mine IoT) are powered by batteries, and wireless charging using mobile chargers (MCs) is an effective way to make nodes work sustainably. A novel hybrid charging method combining the controlled and opportunistic MCs (C&O charging) is proposed in this study. Workers (such as the repairmen and gas inspectors) carrying portable chargers are proposed to be opportunistic MCs to provide an incidental charging service for the surrounding rechargeable Mine IoT nodes while doing its own work to reduce the payload of controlled MCs. The hybrid charging model based on the incidental charging ability of the opportunistic MC is constructed and the scheduling strategy of the controlled MC and the queueing management scheme of the charging request are also proposed. The simulation results indicate that the power demands of the majority of the nodes in the maintenance areas can be met or partially met by opportunistic MCs and the charging time of C&O charging is greatly decreased compared to that of only using controlled MCs.
The impact of an oil droplet on an oil layer on water

Abstract We present a study of droplet impingement on a two-layer liquid, specifically an oil droplet impinging on a layer of oil on water. In our experiments, the diameter and impact velocity of the droplet and the thickness of the oil layer were varied, and the maximum depth of the crater and the maximum height of the Worthington jet were measured. When the thickness of the oil layer was less than ${\sim }1.6$ times the droplet diameter, the depth of the crater depended on the thickness of the oil layer. Otherwise, the two-layer liquid behaved like a single layer. This observation is rationalized by considering the oil–water interface, whose deformation is negligible when the oil layer is thick but becomes significant when the oil layer is thinner. We define an effective Weber number for the two-layer liquid and show that the height of the Worthington jet is proportional to this effective Weber number.
Assessment of Calcium Phosphate Nanoparticles as Safe Mineral Supplement for Broiler Chicken

An experiment was carried out with the objective with assessment on the safety of calcium phosphate nanoparticles as mineral supplement to broiler chicken. With the help of an indigenous laboratory equipment calcium phosphate nanoparticles were prepared by wet chemical method. Calcium phosphate nanoparticles were analyzed for its size and shape using TEM. It was ranged from 20 to 90 nm with spherical shape. The calcium and phosphorous content was estimated. Results show that 30.81 per cent calcium and 15.48 per cent phosphorus. Using the Vero cell line in vitro cytotoxicity study carried out that indicated 10 mg/ml of calcium phosphate nanoparticles did not provoke observable cellular insult. The in vivo assessment was also done using hematological and serum biochemistry parameters in birds fed with calcium phosphate nanoparticles at graded concentration at 50, 60, 70, 80, 90 and 100% of the phosphorus content of coarse particles of dicalcium phosphate in the diet from day old to 28 days. The results indicated that Calcium phosphate nanoparticles did not exert any significant (P<0.05) influence on haemoglobin, Packed cell volume, total erythrocytes count, total leucocytes count, and differential count of WBC compared to control (fed with dicalcium phosphate). The inclusion of calcium phosphate nanoparticles from 50 to 100% did not have any significant negative influence on the serum glucose, total protein, albumin, triglyceride, cholesterol, serum urea, creatinine, serum Aspartate amino Transferase (AST), Alanine amino Transferase (ALT) and Alkaline Phosphatase (ALP). Hence, it was concluded that calcium phosphate nanoparticles are safe to use since an adult bird would consume at a concentration not more than 6.4 mg/ml which is well within the safe level of 10mg/mlas identified by in vitro cytotoxicity test on vero cell line.
The effects of calcite silicon-mediated particle film application on leaf temperature and grape composition of Merlot (Vitis vinifera L.) vines under different irrigation conditions

Aim: This study examined whether the application of calcite-silicon mediated particle film (CaPF) at veraison can mitigate a drought-induced increase in leaf temperature on grapevine, thus contributing to improved leaf functionality, yield and grape composition traits.Methods and results: A total of 48 five-year-old Merlot (Vitis vinifera L.) vines grafted onto SO4 were grown (in 20 L PVC pots) under Mediterranean conditions (Southern Italy). The vines were pruned to a single spur with 3 winter buds irrigated daily to 100 % field capacity, and fertilised weekly.At veraison and using a 2×2 factorial experimental design, the two main factors, thermoregulation and water, were imposed at two levels: spraying with a thermoregulation compound (CaPF) and no spraying (NS); irrigation (WW) and drought stress (D)). A group of 24 vines was subjected to a 15-day drought period by receiving, every day, 25 % (D) of the daily water consumption of WW vines. The other 24 vines continued to be fully irrigated on a daily basis (WW). Twelve vines per group were sprayed (WW+CaPF, D+CaPF) with calcite-silicon mediate (3 % V/V) at the beginning of drought imposition, the remaining 24 vines were not sprayed (WW-NS, D-NS). Soil water moisture and stem water potential values were monitored from 11.30 to 13:30 nearly every week, and other vegetative and reproductive parameters were also measured.During the experiment, air temperature peaked at ≈35°C at midday, VPD at about 3.7 kPa and PAR reached ≈2000 µmol m-2 s–1. Results show that in CaPF sprayed vines, leaf-air temperature differences were lower than in unsprayed vines in both irrigated and drought stressed groups. WW+CaPF vines retained significantly more leaf area and showed the highest value of accumulated vine transpiration.Conclusion: Calcite-silicon mediated particle film could enhance the resilience of grapevine to adverse environmental conditions and may contribute to preserve terroir elements in highly reputed wine grape growing areas.Significance of the study: The study showed that foliar application of calcite silicon-mediated processed particles films can be used in arid regions to mitigate leaf temperatures in grapevines.
