Synthesis, Structural and Magnetic Properties of Chromium Substituted Mn-Zn Ferrite

Substitution of chromium in Mn-Zn ferrite and its effect on structural and magnetic properties has been studied. Samples were synthesized by combustion method and sintered at various temperatures (Ts). XRD patterns indicate that the samples are of single phase cubic spinel structure. The lattice parameter decreases with increase with substitution of Cr 3+ content. Average grain size (D), bulk density (ρB), initial permeability (μi / ), Néel temperature (TN) decrease with the increase in chromium content. ρB was found to increase with increase in Cr 3+ content as the Ts is increased. The Ts affect the densification, grain growth and μi / of the samples. μi /

Challenges Experienced by Teachers in Implementing the Pre-Primary Education in Zanzibar

: This study examined challenges experienced by teachers while implementing PPE in Zanzibar. The study employed qualitative methodology and a case study design. A total number of 18 respondents participated in the study where by nine were pre-primary school teachers, six were pre-primary school head teachers and three were quality assurance officers from the Ministry of Education. Data was collected by using a focus group discussion, semi structured interviews and documents. The study concluded that inadequate teaching and learning materials, low parental involvement, in-adequate training, shortage of qualified teachers, low parental economic status, shortage of play grounds, learners’ disciplinary and behavioral issues and overcrowded classrooms were key challenges encountered by teachers in the implementation of the PPE curriculum. The study recommends that government authorities that oversee PPE in Zanzibar should provide in-service training opportunities for teachers to be well prepared to handle the PPE more effectively. Relevant authorities should ensure construction of more classrooms to match with the enrollment ratios. Furthermore, there is a need to sensitize parents to get involved in their children’s school affairs for better outcomes to be realized.
The Interpersonal Measure of Psychopathy Construct and Incremental Validity in Male Prisoners

The authors examined the construct and incremental validity of the Interpersonal Measure of Psychopathy (IM-P), a relatively new instrument designed to detect interpersonal behaviors associated with psychopathy. Observers of videotaped Psychopathy Checklist–Revised (PCL-R) interviews rated male prisoners ( N = 93) on the IM-P. The IM-P correlated significantly with the PCL-R total score. Moreover, the IM-P was preferentially related to the interpersonal rather than the affective and antisocial lifestyle features of psychopathy. IM-P scores were significantly correlated with age, antisocial behaviors, and self-reported fear, anxiety, and socialization (in reverse). Hierarchical multiple regression analyses demonstrated that although the IM-P exhibited incremental validity beyond the PCL-R total score in detecting self-reported fear, anxiety, and several personality traits, it did not exhibit much incremental validity beyond PCL-R Factor 1. These findings raise questions concerning the unique assessment contribution of the IM-P beyond PCL-R Factor 1. Potential reasons for these findings and alternative means of enhancing the interpersonal assessment of psychopathy are discussed.
The interaction region of a turbulent plane jet

All three velocity fluctuations and the temperature fluctuation have been measured in a slightly heated turbulent plane jet. Attention is focused on the interaction region of the flow, which is situated between the location where the two mixing layers nominally merge and that which corresponds to approximate self-preservation. For the jet considered here the mixing-layer structures are symmetrical with respect to the centreline, and when they meet in the interaction region the redistribution of turbulence quantities is dramatic. This redistribution is examined in detail. Also examined is the effect of the generation, in the interaction region, of new structures, asymmetric with respect to the centreline, which evolve into the self-preserving flow region downstream. Turbulence parameters, such as the turbulent Prandtl number, probability density functions, skewness and flatness factors, are also presented, primarily to guide computer simulations of this flow. The superposition procedure of Weir, Wood & Bradshaw (1981), which assumes that the turbulence structure of each mixing layer is not significantly altered by the interaction, is not appropriate to the present flow.
Quasi-homeomorphisms and lattice-equivalences of topological spaces

In his paper [1], Thron introduced a concept of lattice-equivalence of topological spaces. Let C(X) denote the lattice of all closed sets of a topological space X. Two topological spaces X and Y are said to be lattice-equivalent if there exists a lattice-isomorphism between C(X) and C(Y). It is clear that for any continuous function f: X → Y, the induced map ψf: C(Y) → C(X), defined by ψ(F)=f−1(F), is a lattice-homomorphism. Furthermore, if h: X→ Y is a homeomorphism then ψh: C(Y) → C(X) is a lattice-isomorphism. Thron proved among others that for TD-spaces X and Y, any lattice-isomorphism: C(Y) → C(X) can be induced by a homeomorphism f: X → Y in the above way.
TEACHER'S STRATEGY IN DISCIPLINE ON STUDENT LEARNING ONLINE IN THE COVID-19 PANDEMIC (CASE STUDY AT SDN 01 IWUL, SDN 02 IWUL, SDN 03 IWUL, PARUNG DISTRICT, BOGOR)

Discipline of students in the teaching and learning process is very important to support the suSDN 01 Iwul, SDN 02 Iwul, SDN 03 Iwuless of the teaching and learning process in the classroom during the COVID-19 pandemic. However, many students lack discipline when participating in the teaching and learning process during the COVID-19 pandemic, such as being late for a Zoom class, turning off the camera unilaterally for various reasons, and turning off the sound when asked to participate for technical reasons. This study aims to find out a clear picture of the teacher's strategy in disciplining student learning online during the Covid-19 pandemic at SDN 01 Iwul, SDN 02 Iwul, and SDN 03 Iwul. The approach in this study is a qualitative approach, the method used is a descriptive method. Sources of data used in this study is primary data. Primary data were obtained from the answers to interviews conducted with key informants who were designated as research samples. The result of this study is that student discipline in the implementation of online learning during the Covid-19 pandemic at SDN 01 Iwul, SDN 02 Iwul, and SDN 03 Iwul is quite good. Teachers teach based on lesson plans and syllabus and teach with mixed methods (blended learning) using whats up group applications, google class rooms, and google meet in learning. The teacher's strategy in disciplining student learning online is by making learning contracts, providing understanding material about discipline with the narrative method. And being an example by always being on time, besides that, the teacher always gives assignments to get students to be disciplined in learning. The obstacles that oSDN 01 Iwul, SDN 02 Iwul, SDN 03 Iwulur after the student discipline strategy is implemented are that there are still students who do not do assignments on time, student participation in conveying arguments or opinions is still low so that learning runs monotonously. In addition, students often commit plagiarism in completing their assignments. The efforts made are by always advising and providing an understanding of the importance of discipline and providing good examples and examples to students. Create groups, so that students are more active in learning because they have to present and discuss. The next step, if three times the student is reprimanded, the student is not also present in the online class and does not collect assignments, then the teacher asks the homeroom teacher and BK teacher for help to reprimand the student.
Tuning phonon transport spectrum for better thermoelectric materials

ABSTRACT The figure of merit of thermoelectric materials can be increased by suppressing the lattice thermal conductivity without degrading electrical properties. Phonons are the carriers for lattice thermal conduction, and their transport can be impeded by nanostructuring, owing to the recent progress in nanotechnology. The key question for further improvement of thermoelectric materials is how to realize ultimate structure with minimum lattice thermal conductivity. From spectral viewpoint, this means to impede transport of phonons in the entire spectral domain with noticeable contribution to lattice thermal conductivity that ranges in general from subterahertz to tens of terahertz in frequency. To this end, it is essential to know how the phonon transport varies with the length scale, morphology, and composition of nanostructures, and how effects of different nanostructures can be mutually adopted in view of the spectral domain. Here we review recent advances in analyzing such spectral impedance of phonon transport on the basis of various effects including alloy scattering, boundary scattering, and particle resonance.

Conclusion: PSARP and its modifications can improve the dismal outcome found in adult patients who have undergone conventional repairs.
Classiﬁcation with a domain shift in medical imaging

In medical imaging, the amount of unlabelled data often exceeds that of labelled data [28]. When labelled data is lacking, we may still be able to obtain training sets that are big enough for training large-scale deep models, but that are from a different data distribution from the actual data to be encountered at test time. In particular, retinal images are obtained through devices from different vendors, which have diverse characteristics. Moreover, shifts in data distribution may be found even among datasets of images collected with devices from the same vendor due to patient cooperation during the examination or interoperator variability [20, 14]. In this study, we propose a method that is able to exploit additional unlabelled datasets, possibly with a domain shift, to improve predictions on our labelled data. In order to do so, we exploit a Convolutional Neural Network (CNN) architecture with three classifiers that share a common feature backbone: (1) classifies labelled samples, (2) determines the dataset of origin of each sample, and (3) solve a self-supervised task, in particular predicting image rotations and solving Jigsaw puzzles, on unlabelled data. Classifier (2) is trained to not be able to distinguish between different datasets, so that data is projected into a common feature space, while the self supervised learner (3) learns features from unlabelled data, that are shared through the common feature backbone. Previously, in [6], Carlucci et al. tested how solving Jigsaw puzzles on unlabelled samples, while classifying labelled images, helps in learning more general representations. However, there are two key differences with respect to our work. First, their architecture does not include a domain classifier. Second, they focus on the classification performance on the unlabelled dataset, while we focus on the performance on the labelled one. The main contributions of our work are the following: 1) we proposed a new architecture that is able to exploit unlabelled data with a domain shift to improve predictions on labelled data. It works by learning features through self-supervised learning (SSL) while projecting all the data onto the same space to achieve better transfer; 2) we run a series of experiments on Office-31 dataset, to test that our method can be successfully applied to natural images; 3) we tested this method on retinal images, in particular for age-related macular degeneration (AMD) and diabetic retinopathy (DR) grading, consistently improving the results of the baselines (from 78.83% to 83.53% average test accuracy on AMD grading and from 60.00% to 67.79% average test accuracy on DR grading). We qualitatively and quantitatively verified, through saliency maps, how the proposed method is able to focus more

Systematic measurements of the dielectric properties of BaTiO3 have been done for two cases: embedded grains and fine-grained pressed powder. The influence of the size and shape of the grains, and of the method of preparation of the samples, has been studied.
THE IMPACTS OF COVID-19 PANDEMIC ON BEHAVIORAL CHANGES IN TRANSPORTATION ACTIVITY TO A FOREST RECREATION AREA AND CAUSALITY ANALYSIS IN TURKEY

With COVID-19, increased vehicle use for recreational purposes was observed. This study examines monthly changes in the number of transportation vehicles to a recreation area between 2018– 2019, compared to 2020 in Turkey. Also, based on 17 weeks of data between 1 June-27 September 2020, causality relationships were investigated between the number of COVID-19 cases and deaths and the number of vehicle entries to the recreation area using digital card payment. According to the results, in 2018-2019, a similar seasonal trend was observed in the total number of vehicles. However, the number doubled at the end of 2020. Also, results showed a causal relationship between the number of deaths caused by COVID-19 and the number of vehicles entering the forest recreation area. However, there was no relationship observed between the number of COVID-19 cases and the number of vehicles. Furthermore, a causal relationship was found between the number of times the digital card was used to pay fees and the number of cases, but not the number of deaths. Therefore, a general evaluation results of the study concluded that the COVID-19 pandemic affected activity in the forest recreation area, and thus, it should be considered a factor in transportation management.
Pressure‐Effect Measurements Using a Vibrating‐Coil Magnetometer

A vibrating‐coil magnetometer used in conjunction with a helium‐gas pressure‐generating system has proved to be a versatile new means of studying the effects of hydrostatic pressure on magnetic properties. The sensitivity of this system permits the measurement of paramagnetic susceptibilities on powder samples of the order of 0.1 g. Paramagnetic measurements on MnAs, which undergoes a hexagonal‐orthorhombic transition upon application of pressure, have directly established that the transition is accompanied by a change of the manganese ions from a high‐spin to a low‐spin state. Regions in the pressure‐temperature space in which the high‐pressure (orthorhombic) phase is metamagnetic and ferromagnetic have been delineated. In addition, the pressure dependence of the magnetic‐ordering transition temperature has been determined for a number of materials, and the results are consistent with the predictions of Good‐enough where applicable. Finally, it has been established that this instrument can be used to stu.
INFLUENCE OF ROOTSTOCK CULTIVAR COMBINATION ON THE CONTENT OF HEAVY METALS, MICRO AND MICROELEMENTS IN THE FRUITS OF PLUMS

The research was conducted to evaluate the effect of rootstock cultivar combinations on the content of heavy metals, micro, and macronutrients in the fruits of plums. The study was conducted in Brestnik village, situated at 3.5 km distance from the source of pollution - the Non-Ferrous Metal Works near Plovdiv, Bulgaria. Three plum cultivars of “Stanley”, “Jojo“ and “C. Lepotica“ were studied on the rootstocks of GxN15, GF 677, Wavit, Ishtara and Myrobalan for the content of heavy metals, macro, and microelements in the fruits of plums. The content of heavy metals, macro and microelements in the fruits are different for each rootstock combination, depending on the cultivar. Plum fruits tested negative for the presence of Cd, whereas Pb levels were within maximum permissible concentration. The effect of rootstocks on the accumulation of macro and microelements (K, Ca, Mg, Fe, Zn, Cu, Mn and B) was significant. The results showed that the rootstocks strongly affected the fruit element uptake of plums
Subjective Housing Price Expectations, Falling Natural Rates and the Optimal Inflation Target

U.S. households’ housing price expectations deviate systematically from rational expectations: (i) expectations are updated on average too sluggishly; (ii) following housing price changes, expectations initially underreact but subsequently overreact; (iii) households are overly optimistic (pessimistic) about capital gains when the price-to-rent ratio is high (low). We show that weak forms of capital gain extrapolation allow to simultaneously replicate the behavior of housing prices and these deviations from rational expectations as an equilibrium outcome. Embedding capital gain extrapolation into a sticky price model featuring a lower-bound constraint on nominal interest rates, we show that lower natural rates of interest increase the volatility of housing prices and thereby the volatility of the natural rate of interest. This exacerbates the relevance of the lower bound constraint and causes the optimal inflation target to increase strongly as the natural rate falls. JEL Codes: E31, E44, E52, E58
Ameliorative Effect of Dandelion Leaves Extract Against Liver Injury Induced by Schistosomiasis in Mice

The present study is planned to investigate the effect of dandelion leaves water extract (DWE) on Schistosomiasis. Thirty-five adult male albino mice weighing 20-25 g were used and divided into two main groups, the main first group served as a normal control group without infection (n=7); the second main group was infected with S. mansoni (n=28). After 45 days post-infection the second main group was divided into four subgroups; the first subgroup infected with S. mansoni without treatment (IC) and served as positive control group, the second subgroup infected with S. mansoni then treated by praziquantel (PZQ), the third subgroup infected with S. mansoni then treated by DWE, and the fourth subgroup infected with S. mansoni then treated by DWE in combination with PZQ. The results indicated that administration of combined DWE+PZQ is more effective in all parameters than PZQ or DWE and exhibited highly significantly reduced parasitological parameters, the number and diameter of hepatic granulomas, and histopathological changes in the liver as compared to the untreated infected group. The results also showed that the administration of DWE+PZQ remarkably reduced AST and ALT activities and increment of serum albumin. These amelioration effects were observed in DWE+PZQ treated group, then PZQ‑treated group, followed by the group treated with DWE only. This study concluded that dandelion leaves water extract can be added as a potential treatment against schistosomiasis when combined with the anti-schistosomal drug praziquantel.
INCORPORATION OF THE NATIVE CICHLIDS TENGUAYACA, PETENIA SPLENDIDA , AND CASTARRICA, CICHLASOMA UROPHTHALMUS INTO SUSTAINABLE AQUACULTURE IN CENTRAL AMERICA IMPROVEMENT OF SEEDSTOCK QUALITY AND SUBSTITUTION OF FISH MEAL USE IN DIETS

INTRODUCTION To achieve fish culture at a commercial scale, basic and applied research need to be carried out in order to allow the closure of the cycle of life of the species. However, in Mexico the focus for this activity has been for introduced species such as tilapia and trout, where its technology is already known (Rojas y Mendoza, 2000). For this reason the research for the culture of native species has reached only a minimum scale of production. In this sense, Southeast of Mexico has a lot of native species including cichlids which represent a potential resource for human consumption. The most important species are the castarrica (Cichlasoma urophthalmus) and tenguayaca (Petenia splendida) which have high potential for culture (Steeffens, 1987; Luna, 1997).
MORPHOMETRIC, REPRODUCTIVE AND ENVIRONMENTAL BIOMARKER ANALYSIS OF A CRUSTACEAN SPECIES ATYAEPHYRA DESMARESTI (MILLET, 1831) FROM NORTHEAST ALGERIA

Comparative study was carried out on classical morphometric reproductive and biochemical parameters concerning populations of Atyephyra desmaresti sampled in northeast Algeria: the mouth of the Mafragh River with El Battah (site 1) is located in Annaba’s Gulf, and Oubeira (site 2) and Tonga (site 3). Lakes are located in El Kala National Park. Principal component analysis revealed a very significant correlation between the morphometric characteristics of A. desmaresti in each site. Growth process seems relatively similar in the analyzed population except some abnormal values measured on the rostrum of individuals from site 2. The morphometric analysis also revealed a weak sexual dimorphism and higher abundance of A. desmaresti at site 2. The reproductive parameters analysis exhibited the following decreasing order in fecundity: site 3> site 1> site 2. As for egg diameter and vitelline (Vn) contents, the following decreasing order was observed: site 2> site 3> site 1. Biochemical analyses revealed significant differences in acetylcholinesterase (AChE) activity; moreover, a significant induction of glutathion S-transferase (GST) activity and a high significant level of metallothioneins (MTs) were recorded in A. desmaresti. These differences are discussed according to the characteristics of the studied sites. Data obtained could be useful in improving our knowledge of the Algerian shrimps.
