Physico-Chemical and Pharmaco-Technical Characterization of Inclusion Complexes Formed by Rutoside with β-Cyclodextrin and Hydroxypropyl-β-Cyclodextrin Used to Develop Solid Dosage Forms

The aim of our study was to obtain rutoside (RUT) inclusion complexes in β-cyclodextrin (β-CD) and in hydroxypropyl-β-cyclodextrin (HP-β-CD), in a 1:1 molar ratio, using the lyophilization method of complexation in solution. The complexes were confirmed and characterized, in comparison with the raw materials and their simple physical mixtures, by SEM, DSC, and FT-IR analyses. The antioxidant activity of the compounds was assessed by using the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and 2’-azino-bis(3-ethylbenzothiazolin-6-sulfonic) acid (ABTS) radicals, determining the radical scavenging activity, and by ferric reducing antioxidant power (FRAP) assay. The results revealed superior antioxidant ability for the inclusion complexes towards rutoside alone. The inclusion complexes were used as active ingredients in formulations of immediate-release tablets. The preformulation studies were performed on the powders for direct compression obtained after mixing the active ingredients with the excipients (Avicel PH 102, Polyplasdone XL-10, magnesium stearate, and talc). The materials were assessed for particle size, flowability, compressibility, and moisture content, establishing they are suitable for a direct compression process. The tablets were characterized regarding their pharmaco-technical properties and the results proved that the formulations lead to high-quality delivery systems, showing a good mechanical resistance with a low friability, excellent disintegration times, and satisfying dissolution rate. The performances were very similar for both formulations and the physico-mechanical properties of the tablets are not influenced by type of the used cyclodextrin, but the RUT- HP-β-CD tablets presented a higher dissolution rate.
Temperature-Dependent Mixing behaviours of Bi -Mg Liquid Alloys

ABSTRACT Bi – Mg is a strongly interacting system (the free energy of mixing > 3 RT at equiatomic composition), the compositional dependence of the thermodynamic properties (free energy of mixing, heat of mixing and entropy of mixing) exhibits asymmetric behaviour about equiatomic composition and are in well agreement with experimental data literature. Such an interesting feature is explained here through complex formation model on the basis that a complex of the form Bi2Mg3 exists in the bulk phase. Its energetics is used to investigate the structural properties (concentration fluctuation in long wavelength limit and chemical short-range order parameter) and the transport property (ratio of mutual diffusion coefficient to intrinsic diffusion coefficient). The mixing behaviour of Bi – Mg system is further explored through the study of coefficient of viscosity, surface composition and surface tension. Our study indicates that the surface is enormously rich with Bismuth concentrations throughout the composition of the alloys.
Determination of Proximate Composition and Anti-Nutritional Content of Cassava in Jimma Zone Ethiopia

Cassava is a dominant staple food for many developing countries, particularly, in humid and sub-humid tropics. In this study, the proximate composition and cyanide content of cassava tuber grown in Jimma Zone were investigated. Cassava samples were collected from five selected Woredas (Districts) of the Zone, where the plant usually grows. Nutritional compositions such as crude fat, protein, and fiber as well as cyanide contents were considered in this study. Accordingly, the crude fat, protein, and fiber content of the studied cassava root ranged from1.38-3.06%, 1.32-1.90%, and 1.58-2.96%, respectively. The results of the nutritional composition of analyzed cassava root samples were rich in crude fat, protein, fiber, and carbohydrate. The level of cyanide gives its value compared to the limits set by the World Health Organization was low and it may not cause harmful effect on human health.
COMPARATIVE EVALUATION OF PHYSICAL PROPERTIES OF SOME YEMENI CRUDE AND FUEL OIL

Due to the high significance of crude oil to modern society as a source of energy and as raw material for a wide chemical and petrochemical industries; in this study, we evaluate the characteristics of certain Yemeni crude, and fuel oils specifically Mareb crude oil blend, Masila crude oil blend plus two samples from Sounah and Hijah oil fields in Masila basin. The general specifications of these crudes and fuel oils are determined and compared with some other regional and international types including Brent and West Texas benchmark crudes using the published data in the specialized literature. It is revealed that Mareb crude oil blend is the lightest and sweetest crude oil followed by Sounah crude while Masila is considered Medium crude and Hijah field is the heaviest with medium sulfur content. Mareb, Masila blends, and Sounah field fuel oils are considered low sulfur fuel oils with sulfur content below the 1% standard marketable fuels; while the Hijah fuel oil slightly above, and this is absorbed within the marketable blend.
EFFECT OF ADDITION PROTECTED FATTY ACIDS IN RUMINANT RATIONS ON PRODUCTIVE PERFORMANCE OF SUFFOLK X OSSIMI CROSSBRED EWES DURING DIFFERENT PRODUCTION STAGES

This study was conducted to evaluate the effect of dietary supplementation of protected fatty acids (FA) on nutrient digestibility, rumen parameters, some blood components, milk yield and its composition and lambs growth performance during the pre-weaning period (2 months old) of Suffolk x Ossimi ewes. A total of 36 pregnant ewes, weighing on the average 64.89±1.57 kg in their 2nd – 4th parities and aged 2.5 – 4.5 years were divided into three similar groups according to their body weight (12 ewes each) using a complete randomized block design . The feeding trial started 60 days before lambing (late pregnancy period) and continued 60 days after lambing (suckling period). The experimental rations were offered into animals with the rate of 0, 4 and 6% calcium-soap as protected fatty acids (based on DM intake). Body weight, total gain and daily gain of the new born lambs were recorded during the preweaning period (suckling period). The basal rations composed of 60% concentrate feed mixture (CFM) and 40% roughage (berseem 30% + rice straw 10%, RS). Three digestibility trials were carried out using nine Suffolk x Ossimi crossbred rams with average 62 kg BW and aged 2-2.5 years to determine the digestibility and feeding values of the experimental rations. Data showed that significant higher digestibility at (P <0.05) of OM, CP, CF, EE and NFE for fat supplemented groups than those of control one. Rumen parameters (pH, total VFAs and ammonia-N concentration) were higher in supplemented groups than those of the control one. Values of concentrations of blood plasma total protein and its fractions, glucose, total cholesterol, triglycerides and total lipids of experimental ewes were higher in for supplemented groups than that of control one in the two stages of the whole production cycle. Supplemented fat treatments (group) led to significant increases in birth, weaning weights and total gain of lambs, and the highest values were occurred with FA6. Milk yield was higher significantly in supplemented groups than that of control one as well as its composition (fat, total solids and protein, %) were followed the same trend of milk yield among treatments. Generally, it could be concluded that the supplementation of calcium salt of fatty acids at different levels (FA4 or FA6) for rations of Suffolk x Ossimi crossbred ewes improved digestibility, feeding values, increased lambs birth weight and milk yield and its composition beside better feed efficiency, with superiority of 6% level (FA6).
Calibration of an empirical model for moisture content assessment and monitoring in compacted tropical soils used in the subgrade of road pavements

Subgrade moisture variation monitoring and control is important due to its influence on road pavement performance and service life. The precise application of non-invasive techniques such as time domain reflectometry (TDR) and ground penetration radar (GPR) in compacted tropical soils depend on calibration models, that consider their mineralogical composition and geotechnical properties. The present work aims to determine calibration models that relate dielectric permittivity with moisture variation in compacted tropical soils. TDR technique was used with low-cost probes and soil calibration columns developed at laboratory for reading dielectric permittivity and define its relationship with moisture. Results showed that through laboratory standardized procedures, it is possible to determine calibration models according to the required accuracy in moisture control in the subgrade. It was found that the high density and magnetic properties of tropical soils significantly influenced the determination of dielectric permittivity and consequently in moisture estimates, hence reaffirming the need of specific calibrations for these types of soils .
Zero Average Surface Controlled Boost-Flyback Converter

The boost-flyback converter is a DC-DC step-up power converter with a wide range of technological applications. In this paper, we analyze the boost-flyback dynamics when controlled via a modified Zero-Average-Dynamics control technique, hereby named Zero-Average-Surface (ZAS). While using the ZAS strategy, it is possible to calculate the duty cycle at each PWM cycle that guarantees a desired stable period-1 solution, by forcing the system to evolve in such way that a function that is constructed with strategical combination of the states over the PWM period has a zero average. We show, by means of bifurcation diagrams, that the period-1 orbit coexists with a stable period-2 orbit with a saturated duty cycle. While using linear stability analysis, we demonstrate that the period-1 orbit is stable over a wide range of parameters and it loses stability at high gains and low loads via a period doubling bifurcation. Finally, we show that, under the right choice of parameters, the period-1 orbit controller with ZAS strategy satisfactorily rejects a wide range of disturbances.
Determinant factors of Indonesian muslim behavior in choosing halal products

This research aims to examine the factors influencing the Indonesian Muslim community’s actions in choosing halal items. This objective is accomplished by evaluating the factors of variable creation that affect halal product selection. 183 Muslim respondents in Indonesia collected data for the study by filling out questionnaires. There are nine variables in the questionnaire survey segment: personal social perception, halal certification, halal awareness, trust, subjective norms, satisfaction, attitude, religiosity, and interest. Data were obtained based on participants’ availability and willingness to participate in selecting the questionnaire. The approach used is quantitative descriptive, namely, factor analysis, to determine the factors that form variables. One of the most important results is that the nine variables were selected to create an element that significantly influences people’s behavior in choosing halal items. Next are satisfaction, personal social perception, subjective norms, attitude, halal certification, interest, trust, and halal awareness. The religiosity variable results give the most significant contribution of importance in shaping the variables.

Covariational reasoning patterns of high school students in problems of correlation and linear regression / Patrones de razonamiento covariacional de estudiantes de bachillerato en problemas de correlacion y regresión lineal

The topics of correlation and linear regression constitute a complex and subtle system of statistical and mathematical ideas whose teaching-learning raises numerous practical and theoretical problems. In this research paper, the patterns of reasoning that students exhibit, under the approach of informal inferences when they face problems of correlation and regression line are identified. To achieve this, activities were implemented in two stages: in the first stage, two problems (one of estimation and other of best-fit line) were applied to be solved using pencil and paper; the second stage incorporates the use of the Fathom software.
Adaptation of Winter Barley Cultivars to Inversion and Non-Inversion Tillage for Yield and Rhynchosporium Symptoms

Modern cereal cultivars are highly adapted to, and normally bred and trialled under, high input, high soil disturbance conditions. On-farm conditions are often suboptimal for high yield and frequently use minimal soil tillage, sometimes no-tillage, and therefore, cultivars may be differentially adapted to such conditions. We report a series of trials across 10 years comparing multiple cultivars within years and smaller numbers across years to identify stable cultivars showing preferential adaptation to different levels of soil tillage. Cultivars responded differentially to inversion and non-inversion tillage but were not affected by the level of cultivation within each of these tillage types. Yield declined over time but much more so in the non-inversion tillage treatment. Rhynchosporium symptoms were also increasingly suppressed in the non-inversion tillage type. Several cultivars were identified that showed strong adaptation to tillage type, and some of these were consistent across several trial years. These cultivars can be used to identify traits and genotypes associated with tillage adaptation to target breeding for on-farm conditions.
The Effects of Behavioral Biases on Investment Performances of Individual Investors in the Indonesian Stock Market

This paper identifies the existences of behavioral biases in the Indonesian stock market and examines the effect of the behavioral biases on individual investment performance. We use quantitative analysis approach to explore our research purpose. To be specific, individual investors in Indonesia have behavioral biases of overconfidence bias, loss-aversion bias, anchoring and adjustment bias, mental accounting bias and confirmation bias. In addition, we find that confirmation bias and mental accounting bias are positive relationship with investment performance, whereas loss-aversion bias and anchoring and adjustment bias are negative significant relationship with investment performance.
Synchrotron Intensity and Polarization Gradients: Tools to Obtain the Magnetization Level in a Turbulent Medium

Synchrotron intensity and polarization gradients (SIG and SPG), proposed by Lazarian et al. and Lazarian & Yuen, present a new way to recover the mean magnetic field direction in the plane of the sky. To measure the magnetization level, Lazarian et al. suggested that the methods used in the context of the “Velocity Gradient Technique” could also be used on the SIG and SPG contexts. In this work we test the two proposed methods, named “top-base” and the circular standard deviation, “S,” to obtain the level of magnetization from synchrotron emission. In order to test the methods, we generate synthetic observations from magnetohydrodynamic computer simulations, with Alfvénic Mach numbers, MA ∈ [0.2,1.7]. Using a Bayesian analysis we find that the circular standard deviations for the SIG and SPG methods are able to recover the magnetization for cases with signal-to-noise ratio ≳5. We found that for weak Faraday depolarization and different angles between the magnetic field direction and the line of sight the magnetization level can still be estimated.
Rushing to the end: Participants’ perceptions of demotivating aspects of online surveys

More and more social science studies are now acquiring data through the internet, reaching participantsonline. Some participants start out engaged and motivated to participate, but progressively slide into“rushing behaviors”. We inquired experts in survey responding about when, in online studies, theywould feel a desire for rushing (defined as speeding with no concerns about the quality of responses). This qualitative approach uncovered Repetition, Survey length and No interest in topic as the threemain features that would motivate these participants to rush in surveys. Subsequent inquiry of thesame participants indicated that repetition concerns the type of questions made (more than stimuli ortask), the execution of the same task more than 5-6 times, or for more than 6 minutes. Survey lengthconcerns a preference for shorter surveys, as well as the subjective experience in which length exceedspreviously set expectations (i.e., longer than announced), contributing to rushing by effectivelylowering the hourly pay rate as the survey increases in length. Interest in topic was reported to beconsistently low, despite not being the main reason to quit the survey. However, a change in expectedlevel of interest in the middle of the survey is reported as a factor that will promote rushing behaviors.We discuss these data as informative regarding how pre-tests of surveys can benefit from theseparticipants’ expertise.
ALDREN: A Methodological Framework to Support Decision-Making and Investments in Deep Energy Renovation of Non-Residential Buildings

Since 2002, the Energy Performance of Buildings Directive (EPBD) has set up the path to improve the efficiency gains in the EU building sector, including measures that should accelerate the rate of building renovation towards more energy efficient systems. Under the 2010 EPBD, all EU countries have established independent energy performance certification systems supported by independent mechanisms of control and verification. The EU directive 2018/844 has introduced different novelties and one of these regards the possibility for the Member States, together with the Long-Term Renovation Strategies (LTRS), to introduce an optional Building Renovation Passport Article 2a.1(c), considered as an empowering document that gives more reliable and independent information on the potential for energy savings that is tied up in their buildings. On 14 October 2020, the European Commission launched its Communication and Strategy on the Renovation Wave initiative, intending to double the current Europe’s renovation rate to make the continent carbon neutral by 2050. However, current practices and tools of energy performance assessment and certification applied across Europe face several challenges. In this context, the ALDREN project is a methodological framework that aims to support decision-making and investment in deep energy renovation of nonresidential buildings, based on a set of procedures (modules) that consist in the step-by-step implementation of protocols to assess the energy performance, indoor environmental quality, and financial value of buildings, before and after the energy renovation. The paper presents the ALDREN overall procedure with a focus on the development of the Building Renovation Passport and its application to an Italian office building.
Educational Research Training in Teacher Training Programs: The Views of Future Teachers

The objectives of this study were to explore teacher student’s views on the research training they receive and know their suggestions for improving it. This was a qualitative study conducted on students in the teacher training programs of a Chilean public university who were distributed into nine focus groups. The findings showed that the students have a rather critical view about the training they receive, particularly due to the lack of continuity of research-related courses and their limited participation in research activities. Regarding how to improve their training, the students suggest providing one research-related course each year, having researchers as teachers, and giving greater visibility to the educational research produced within their university. The study concludes that it is important to promote participation in educational research and that university teacher educators and the entire university community must adopt a broad-ranging view on this subject.
Peer Feedback and Reflective Practice in Public Service Interpreter Training

The paper discusses the importance of student-generated feedback, that is, peer feedback and self-assessment in public service interpreter training. The importance of peer feedback and self-assessment is widely recognised in teaching and learning and benefits include: promoting analytical and critical thinking skills, students’ active participation in the learning process, promoting a collaborative model of teaching and learning, students’ responsibility and autonomy, to name but a few. However, their beneficial character can also be observed in public service interpreter training. The aim of the pilot study conducted among trainee interpreters (MA students) of public service interpreting course was to examine interpreting quality and compare positive (strengths) and negative aspects (weaknesses) of trainee interpreters’ performance identified by them by means of peer feedback and reflection (self-assessment). The trainees participated in simulated public service interpreting sessions and later were asked to reflect on their own as well as their peers’ performance. As seen from data analysis, there are discrepancies between peer feedback and reflection in the perception of students’ strengths and weaknesses and a negative trend can be observed in the case of reflection.
The Influence of Personality Tendency of African Students in China on Their Cross-cultural Adaptation—Empirical Analysis of 7 Universities in Changsha City

Based on the questionnaire survey and semi-structured interview conducted among African students from seven universities in Changsha, this study aims at describing African students' cross-cultural adaptation in China and analyzing the influence of their disposition on such adaptation from the perspective of personality tendency. The research finds that, from the macro perspective, the holistic cross-cultural adaptation of African students in China is affirmative, and their disposition has a positive impact on their cross-cultural adaptation. From the micro perspective, the social life and social acculturation of African students in China are also sanguine. Although there are some difficulties in African students' social interpersonal adaptation, disposition still has a positive impact on their social life adaptation, social and cultural adaptation and social interpersonal adaptation in China. This study can provide decision-making basis and practical reference for the work of international students in colleges and universities. On the basis of this research, it is proposed that different methods should be adopted for students with different personality tendencies in the management of international students, and attention should be paid to the social and interpersonal communication of international students.
