Self-consistent relativistic band structure of the CH3NH3PbI3 perovskite

The electronic structure and properties of the orthorhombic phase of the $\mathrm{CH}{}_{3}\mathrm{NH}{}_{3}\mathrm{PbI}{}_{3}$ perovskite are computed with density functional theory. The structure, optimized using a van der Waals functional, reproduces closely the unit cell volume. The experimental band gap is reproduced accurately by combining spin-orbit effects and a hybrid functional in which the fraction of exact exchange is tuned self-consistently to the optical dielectric constant. Including spin-orbit coupling strongly reduces the anisotropy of the effective mass tensor, predicting a low electron effective mass in all crystal directions. The computed binding energy of the unrelaxed exciton agrees with experimental data, and the values found imply a fast exciton dissociation at ambient temperature. Also polaron masses for the separated carriers are estimated. The values of all these parameters agree with recent indications that fast dynamics and large carrier diffusion lengths are key in the high photovoltaic efficiencies shown by these materials.
Assessment of juvenile delinquency: convergent and criterion validity of the Jesness Inventory - revised - Brazilian - short form

Abstract: The aim of this study was to analyze evidence of convergent and concurrent criterion validity of the scales of the short form of the Jesness Inventory - Revised - Brazilian version. A sample of 597 male adolescents, aged between 12 and 20 years, participated in the study. The evidence of convergent validity obtained indicates that most scales would have maintained their interpretive meaning in the short form. They also indicated the need for further investigations on the Immaturity scale. The concurrent criterion validity suggests that high scores on the scales can differentiate adolescents based on both criteria, Judicialization and Frequency of self-reported delinquency in the last 12 months. Investment in standardized and brief instruments can drive the development of evidence-based practices in the juvenile justice system and, for this, a research agenda is presented.
The essential uniqueness of bounded nonoscillatory solutions of certain even order differential equations.

on [a, °°) for some a ^ 0. For some recent results concerning the behavior of solutions of (1) satisfying either (2) or (3), the reader is referred to the work of D. L. Lovelady [6], and T. T. Read [7]. A solution of (1) which satisfies (2) is said to be strongly decreasing, and a solution satisfying (3) is said to be strongly increasing. If y is a nontrivial solution of (1), then y is oscillatory if it has infinitely many zeros on [0, oo). Equivalently, y is oscillatory if the set of zeros of y is not bounded above. The differential equation (1) is oscillatory if it has at least one nontrivial oscillatory solution. Hereafter, the term "solution of (1)" shall be interpreted to mean "nontrivial solution. " A solution of (1) which is not oscillatory is called nonoscillatory. Clearly, any solution satisfying either (2) or (3) is nonoscillatory. We shall say that equation (1) has property (H) if every nonoscillatory, eventually positive solution satisfies either (2) or (3). S. Ahmad [1] has studied (1) in the case n = 2, and he has shown that (1) is oscillatory if and only if it has property (H). While this result is
Donor–Acceptor Complexes of (5,10,15,20-Tetra(4-methylphenyl)porphyrinato)cobalt(II) with Fullerenes C60: Self-Assembly, Spectral, Electrochemical and Photophysical Properties

The noncovalent interactions of (5,10,15,20-tetra(4-methylphenyl)porphinato)cobalt(II) (CoTTP) with C60 and 1-N-methyl-2-(pyridin-4-yl)-3,4-fullero[60]pyrrolidine (PyC60) were studied in toluene using absorption and fluorescence titration methods. The self-assembly in the 2:1 complexes (the triads) (C60)2CoTTP and (PyC60)2CoTTP was established. The bonding constants for (C60)2CoTTP and (PyC60)2CoTTP are defined to be (3.47 ± 0.69) × 109 and (1.47 ± 0.28) × 1010 M−2, respectively. 1H NMR, IR spectroscopy, thermogravimetric analysis and cyclic voltammetry data have provided very good support in favor of efficient complex formation in the ground state between fullerenes and CoTTP. PyC60/C60 fluorescence quenching in the PyC60/C60–CoTTP systems was studied and the fluorescence lifetime with various CoTTP additions was determined. The singlet oxygen quantum yield was determined for PyC60 and the intensity decrease in the 1O2 phosphorescence for C60 and PyC60 with the CoTTP addition leading to the low efficiency of intercombination conversion for the formation of the 3C60* triplet excited state was found. Using femtosecond transient absorption measurements in toluene, the photoinduced electron transfer from the CoTTP in the excited singlet state to fullerene moiety was established. Quantum chemical calculations were used for the determination of molecular structure, stability and the HOMO/LUMO energy levels of the triads as well as to predict the localization of frontier orbitals in the triads.
Optimizing time and split application of nitrogen fertilizer to harness grain yield and quality of bread wheat (Triticum Aestivum L.) in northwestern Ethiopia

Improper nitrogen application time during the crop growing period is one of the most limiting factor for wheat production. A field experiment was conducted in Northwestern Ethiopia with the objective of determining the appropriate N fertilizer application time for improving bread wheat production. Twelve treatments (½ urea at 50% emergence + ½ urea at tillering, ½ urea at tillering + ½ urea at booting, 1/3rd urea at 50% emergence + 1/3rd urea at tillering + 1/3rd urea at booting, 2/3rd urea at tillering + 1/3rd urea at booting, all urea at tillering, all urea at booting, all N at tillering, all N at booting, ½ N at sowing+ ½ N at tillering, ½ N 50% emergence + ½ N at tillering, 1/3rd N at 50% emergence + 1/3rd N at tillering + 1/3rd N at booting, ½ N at tillering + ½ N at booting) were lied out in randomized complete block design (RCBD) with three replications. The study showed that wheat grain yield and protein content was highly influenced by the environment and indirectly correlated with each other as affected by N time of applications. The grain yield at Adet, Wonberema and Debre Elies was increased by 31%, 14% and 18%, respectively when N was applied with DAP at sowing over the blanket recommendation. At all locations, grain protein content decreased as the number of N split application increased 1 to 3 times. Thus, depending on the purpose of the producers, it can be concluded that application of ½ urea at 50% emergence + ½ urea at tillering with the application of DAP at sowing gave maximum wheat grain yield, while optimum grain protein content was obtained when N was applied after the crop is emerged and would be used in most dominant wheat producing areas of northwestern Ethiopia. Further study should be conducted on split application of blended fertilizers (NPS, NPSBZN etc.).
HEAT TRANSFER IN FEMTOSECOND LASER PROCESSING OF METAL

The short time scales and high intensities obtained during femtosecond laser irradiation of metals require that heat transfer calculations take into account the nonequilibrium that exists between electrons and the lattice during the initial laser heating period. Thus, two temperature fields are necessary to describe the process--the electron temperature and the lattice temperature. In this work, a simplified one-dimensional, parabolic, two-step model is solved numerically to predict heating, melting, and evaporation of metal under femtosecond laser irradiation. Kinetic relations at the phase-change interfaces are included in the model. The numerical results show close agreement with experimental melting threshold fluence data. Further, it is predicted that the solid phase has a large amount of superheating and that a distinct melt phase develops with duration of the order of nanoseconds.
Western Australian Aboriginal young women and community representatives identify barriers to school attendance and solutions to school non-attendance

The barriers to school attendance that affect young Aboriginal people in Australia are diverse, immense and well documented; however, except for a handful of studies, Aboriginal students’ voices receive no platform for policy makers to hear them. In this paper, we present results from yarning circles about barriers to school attendance conducted with young Aboriginal women that participate in an education engagement program called Shooting Stars at Narrogin Senior High School. Yarning circles were facilitated, analysed and discussed within a framework of relatedness, with the researchers embracing their own standpoint, and the standpoint of the Shooting Stars participants, as Indigenous women. The results from these participant yarning circles were discussed with the Shooting Stars Narrogin localised steering committee, and this discussion is presented here, alongside the outcomes, both achieved and projected, to which committee stakeholders have committed. For the most part, the participants and the steering committee discussed racism, teacher–student relationships, and peer connectedness, and how these were related to participant attendance and engagement at school. This paper showcases the power of the yarning circle as a tool for collaboration in that it provides a space to create cohesion through conversation, through contention and through sharing.
Fatou’s lemma in several dimensions

In this note the following generalization of Fatou's lemma is proved: Lemma. Let {fn)n_l be a sequence of integrable functions on a mea- sure space S with values in R+, the nonnegative orthant of a d-dimen- sional Euclidean space, for which ffn—*aGiR+. Then there exists an in- tegrable function f, from S to R+, such that a.e. f(s) is a limit point of VnisV^and ff^a. 1. Introduction. When d = l, the result is a form of Fatou's lemma. The assertion above is applied in mathematical economics (4). 2 It is also strongly connected with the theory of set valued functions (2) or correspondences (3). The nontrivial part of the arguments is lim- ited to the case where 5 is an atomless measure space. In the purely atomic case the lemma is reduced to a simple exercise in series. In any case, the lemma cannot be proved by a successive application of Fatou's lemma d times. A few corollaries of the lemma are proved in §3. 2. Preliminary results and the proof of the lemma. Let (A")"°=1 be a sequence of (nonempty) subsets of Rd. We denote by Lim Sup"^4" the set of all the limit points of the sequences (a"),T-i with anEAn, » = 1, 2, • • ■ . Denote by x-y the inner product, Yt=i xlyl, in Rd.
Synthesis of an inhomogeneous medium from its acoustic transmission response

In 1968 Claerbout showed that the reflection response of a horizontally layered medium can be synthesized from the autocorrelation of its transmission response. During a workshop on passive imaging methods at the 2002 SEG conference, Claerbout showed that this result can be obtained straightforwardly from the principle of conservation of acoustic power. In this paper I briefly review this derivation and show that the 3D generalization can be obtained along the same lines using a power reciprocity theorem. The resulting expression confirms Claerbout9s conjecture that “by crosscorrelating noise traces recorded at two locations on the surface, we can construct the wave field that would be recorded at one of the locations if there was a source at the other. ”
Finite amplitude electroconvection induced by strong unipolar injection between two coaxial cylinders

We perform a theoretical and numerical study of the Coulomb-driven electroconvection flow of a dielectric liquid between two coaxial cylinders. The specific case, where the inner to outer diameter ratio is 0.5, is analyzed. A strong unipolar injection of ions either from the inner or outer cylinder is considered to introduce free charge carriers into the system. A finite volume method is used to solve all governing equations including Navier-Stokes equations and a simplified set of Maxwell’s equations. The flow is characterized by a subcritical bifurcation in the finite amplitude regime. A linear stability criterion and a nonlinear one that correspond to the onset and stop of the flow motion, respectively, are linked with a hysteresis loop. In addition, we also explore the behavior of the system for higher values of the stability parameter. For inner injection, we observe a transition between the patterns made of 7 and 8 cells, before an oscillatory regime is attained. Such a transition leads to a second finite amplitude stability criterion. A simple modal analysis reveals that the competition of different modes is at the origin of this behavior. The charge density, as well as velocity field distributions is provided to help understand the bifurcation behavior.
Incidence of Aphid on Different Brinjal Germplasm Related to Abiotic and Biotic Factors

The study was conducted with BD-7320, BD-7328, BD-9952, BD-10154, BD- 10158, BARI Begun-1, BARIBegun-4, BARIBegun-5, BARIBegun-6, BARIBegun-7, BARIBegun-8 and BARIBegun-9 germplasms of brinjal with a view to understanding the effect of temperature, relative humidity, rainfall and predators on the incidence of aphid during September 2018 to March 2019. Aphid incidence and infestation started from the last week of November and the highest incidence was recorded during 2nd week of January on BD-10154.At that week, aphid showed lower number of incidence on BARI Begun-5, BARI Begun-6, BARI Begun-8 and BARI Begun-9. The highest infestation of aphid was observed on BARI Begun-5 during 2nd week of March, when the lowest infestation was found on BD-9952. Maximum and minimum temperatures showed significant positive correlation, relative humidity (RH) and rainfall revealed non-significant correlation with aphid incidence. Aphid abundance showed highly significant positive correlation with the abundance of predators on all the tested germplasms. Bangladesh J. Agril. Res. 45(4): 371-378, December 2020
Tuberculosis spondylodiscitis in a patient with psoriatic arthritis on targeted synthetic disease-modifying antirheumatic drugs – case report

Tuberculosis (Tb) has been recognised as an important opportunistic infection that occurs in patients with inflammatory rheumatic diseases. The results of global registries show that the risk of reactivation of latent Tb or the development of new Tb infection increases in patients treated with tumour necrosis factor inhibitors (Tnfis). However
Utilisation of Banana Peel as Functional Ingredient in Product Development

: The agro-food industry’s exponential growth of plant waste production is a critical global issue, taking into account its storage, disposal, environmental impact and potential health risks. However, by-product utilisation of agricultural waste for the retrieval of added-value compounds offers new avenues for industrial production and waste management. Bananas waste primarily the peels are potentially a useful source for the substitution of value added products such as dietary fibres, bioactive components, including carotenoids, polyphenols, pro-vitamins as well as essential minerals. This project describes the types and the composition of raw banana peel wastes and the bioactive components of the peel, the processing methods and the possible application of banana peel flour (BPF). Of particular interest, the proximate analysis and physicochemical properties of potential BPF and the properties of the by-product are discussed. This information was then used to identify types of food that is suitable for the production industry. Then, the utilisation of banana peel flour in waffle ice cream cones and yellow noodles were chosen. The formulations of BPF were prepared in three different formulations: 10%, 20% and 30% for banana peel noodles and 5%, 10% and 20% for waffle cones, respectively. Overall, BPF substitutions in these food products have affected and improved the cooking properties, nutritional values, colour, texture and sensory characteristics compared to control without any substitution.
The Impact of Convective Momentum Transport on Tropical Cyclone Track Forecasts Using the Emanuel Cumulus Parameterization

Abstract The influence of convective momentum transport (CMT) on tropical cyclone (TC) track forecasts is examined in the Navy Operational Global Atmospheric Prediction System (NOGAPS) with the Emanuel cumulus parameterization. Data assimilation and medium-range forecast experiments show that for 35 tropical cyclones during August and September 2004 the inclusion of CMT in the cumulus parameterization significantly improves the TC track forecasts. The tests show that the track forecasts are very sensitive to the magnitude of the Emanuel parameterization’s convective momentum transport parameter, which controls the CMT tendency returned by the parameterization. While the overall effect of this formulation of CMT in NOGAPS data assimilation/medium-range forecasts results in the surface pressure of tropical cyclones being less intense (and more consistent with the analysis), the parameterization is not equivalent to a simple diffusion of winds in the presence of convection. This is demonstrated by two data a.
Critical Phenomena for Sequence Matching with Scoring

Consider two independent sequences $X_1,\ldots, X_n$ and $Y_1,\ldots, Y_n$. Suppose that $X_1,\ldots, X_n$ are i.i. d. $\mu X$ and $Y_1,\ldots, Y_n$ are i.i. d. $\mu_Y$, where $\mu_X$ and $\mu_Y$ are distributions on finite alphabets $\sum_X$ and $\sum_Y$, respectively. A score $F: \sum_X \times \sum_Y \rightarrow \mathbb{R}$ is assigned to each pair $(X_i, Y_j)$ and the maximal nonaligned segment score is $M_n = \max_{0\leq i, j \leq n - \Delta, \Delta \geq 0}\{\sum^\Delta_{l=1}F(X_{i+l}, Y_{j+l})\}$. Our result is that $M_n/\log n \rightarrow \gamma^\ast(\mu_X, \mu_Y)$ a.s. with $\gamma^\ast$ determined by a tractable variational formula. Moreover, the pair empirical measure of $(X_{i+l}, Y_{j+l})$ during the segment where $M_n$ is achieved converges to a probability measure $\nu^\ast$, which is accessible by the same formula. These results generalize to $X_i, Y_j$ taking values in any Polish space, to intrasequence scores under shifts, to long quality segments and to more than two sequences.
Effect of Intravenous Fluid and Local Anaesthetic Warming on Core Temperature Following Subarachnoid Block for Caesarean Section

Background: Hypothermia and shivering often complicate spinal anaesthesia for Caesarean section, and has necessitated the search for an effective and affordable warming method for parturient. Aim: To compare the effects of intravenous fluid and local anaesthetic warming on core temperature during Caesarean section under spinal anaesthesia. Methods: One hundred and sixteen consenting parturients aged 18 to 40 years with ASA physical status class II scheduled for elective Caesarean section were recruited into the study. Patients were randomly allocated into groups I, II, III and IV. All the patients were preloaded with 15 ml/kg of normal saline over 15 minutes before institution of subarachnoid block in the sitting position. Warm intravenous fluid and warm intrathecal bupivacaine, warm intravenous fluid and intrathecal bupivacaine at room temperature, intravenous fluid at room temperature and warm intrathecal bupivacaine, and both intravenous fluid and intrathecal bupivacaine at room temperature were administered to patients in groups I, II, III, IV respectively. Data collected included core temperature (tympanic membrane) using a thermoscan, shivering using the 5-point scale of Wrench. Neonatal rectal temperature was measured and adverse effects observed on the parturients recorded. Monitoring of core temperature was continued in the post anaesthesia care unit until full recovery and discharge. Results: All the 116 patients completed the study. While core temperature change was highest (-0.43 ± 0.30) in group IV and lowest in group I (-0.07 ± 0.58), it was -0.16 ± 0.09 in group II and -0.24 ± 0.16 in group III, p=0.001. Hypothermia was observed in group IV, with an incidence of 10.3%. Group IV also had the highest incidence of shivering (31%), followed by group III (10.3%) and group II (6.9%) while group I had zero incidence of shivering. The neonatal temperature was similar across the study groups. Vomiting was recorded in one patient in groups III (3.4%) and IV (3.4%). Bradycardia occurred in two patients in groups III (6.9%) and one patient in group IV (3.4%). Hypotension was observed in two patients in group III (6.9%) and one patient in group IV (3.4%). Conclusion: Warming of intravenous fluid and intrathecal bupivacaine reduced maternal temperature change during Caesarean section under subarachnoid block, but there was no significant difference in the incidence of shivering between the combination of warm intravenous fluid and warm intrathecal bupivacaine, and warm intravenous fluid alone.
Changes in the recreational physical activity (RPA) behaviours caused by COVID-19 lockdown – a case study of Poland

ABSTRACT This article aims to describe, explain and compare the changes in Poles’ recreational physical activity (RPA) behaviours that emerged in response to the restrictions introduced by the Covid-19 pandemic. The literature review revealed gaps regarding this subject. Of particular interest is taking into account the comparison of both the national and international context and the comprehensive approach to explaining the mechanism of change. Based on the literature, the theoretical framework was developed, which was then used to design an online questionnaire. The questionnaire was conducted from 20 May to 31 October 2020 and included 533 respondents. To analyse the data, a combination of quantitative and qualitative analysis methods was used (descriptive statistics and grounded theory techniques). Research has shown that RPA behaviours changed temporally or permanently. The behaviours were partially differentiated by gender and age. In comparison to other countries, it seems to be a result of the range and strictness of the introduced restrictions and national culture. The novelty of the work consists of the combined data analysis methods, which allow for an explanation of the mechanism of changes and a comparison of results with other countries.
Vaccine-Acquired SARS-CoV-2 Immunity versus Infection-Acquired Immunity: A Comparison of Three COVID-19 Vaccines

Around the world, rollout of COVID-19 vaccines has been used as a strategy to end COVID-19-related restrictions and the pandemic. Several COVID-19 vaccine platforms have successfully protected against severe SARS-CoV-2 infection and subsequent deaths. Here, we compared humoral and cellular immunity in response to either infection or vaccination. We examined SARS-CoV-2 spike-specific immune responses from Pfizer/BioNTech BNT162b2, Moderna mRNA-1273, Janssen Ad26.COV2. S, and SARS-CoV-2 infection approximately 4 months post-exposure or vaccination. We found that these three vaccines all generate relatively similar immune responses and elicit a stronger response than natural infection. However, antibody responses to recent viral variants are diminished across all groups. The similarity of immune responses from the three vaccines studied here is an important finding in maximizing global protection as vaccination campaigns continue.
