description: Generalizing the algebraic formulation of the First Fundamental Theorem of Calculus (FFTC), a class of constraints involving a pair of operators was considered in \cite{ZGK2}. For a given constraint, the existences of extensions of differential and Rota-Baxter operators, of liftings of monads and comonads, and of mixed distributive laws are shown to be equivalent. In this paper, we give a classification of the constraints satisfying these equivalent conditions.

description: We analyze contributions to the electric dipole (EDM) and Schiff (SFM) moments of deuteron induced by the CP-violating three-pseudoscalar meson couplings using phenomenological Lagrangian approach involving nucleons and pseudoscalar mesons $P=π, K, η, η'$. Deuteron is considered as a proton-neutron bound state and its properties are defined by one- and two-body forces. One-body forces correspond to a picture there proton and neutron are quasi free constituents of deuteron and their contribution to the deuteron EDM (dEDM) is simply the sum of proton and neutron EDMs. Two-body forces in deuteron are induced by one-meson exchange between nucleons. They produce a contribution to the dEDM, which is estimated using corresponding potential approach. From numerical analysis of nucleon and deuteron EDMs we derive stringent limits on CP-violating hadronic couplings and $\barθ$ parameter. We showed that proposed measurements of proton and deuteron EDMs at level of $\sim 10^{-29}$ by the Store Ring EDM and JEDI Collaborations will provide more stringent upper limits on the CP violating parameters.

description: The study examined the adoption rate of New Rice for Africa (NERICA), technical efficiency differentials of production of these varieties between adopters and non-adopters and the determinants. It further analysed the impact of adoption of NERICA on area cultivated, output, yield, expenditure and total income of rice farmers in the NERICA baseline states in Nigeria. To achieve the objectives, it employed the descriptive statistics, stochastic production frontier and counterfactual outcomes framework of modern evaluation technique (the Local Average Treatment Effect) to analyse 621 rice farmers across the six NERICA baseline states in Nigeria in 2012. The findings show that NERICA adopters were more technically efficient than the non-adopters. In addition, adoption of NERICA was found to significantly increase the areas of land cultivated, output, yield, household expenditure, per capita household expenditure and total income among NERICA adopters by 1.2ha (p < 0.01), 1998.2kg (p< 0.01), 191.2kg/ha (p < 0.1), N13,222.63≈$66.4 (p < 0.05), N2,015.6≈$10.1 (p < 0.05) and N145,098.7 ≈$728.0 (p < 0.01) respectively despite their high level of inefficiency (39 percent) by the adopters. The positive impact of NERICA adoption on rice yields, poverty status measured by the per capita household expenditure and total farm income of farmers is a clear indication that NERICA has the potential to increase rice productivity, reduce poverty and food insecurity. NERICA adoption rate will rise if more farmers are aware of the varieties in the study. Farmers who had adopted, and government at all levels should therefore intensify their efforts to encourage others rice farmers possibly through the extension agents on the need to grow NERICA varieties so as to increase rice production level, reduce rice importation and ensure a sustainable rice production.

description: Dental caries is a multi-factorial disease and the most common human infection that annually are spent millions dollars to control and treat it. Several methods have been proposed so far to control it. The most important control methods it is now include: dental hygiene, proper nutrition, fluoride therapy, the use of non-cariogenic sweeteners. Also, the use of probiotics, nanomaterials, bacteriophages, antimicrobial peptides and anti-caries vaccines can be considered as new perspective of human in the dental caries control field. In addition, the use of complementary and alternative therapies, especially herbal drug therapy recently has been considered. Demonstrating the efficacy of complementary medicine against dental caries and its use in combination with conventional medicine or trial of new methods for decline of dental caries in the future would be hopeful.

description: We extend our previous stochastic cellular automata based model for areal aggregation of prion proteins on neuronal surfaces. The new anisotropic model allow us to simulate both strong beta-sheet and weaker attachment bonds between proteins. Constraining binding directions allows us to generate aggregate structures with the hexagonal lattice symmetry found in recently observed in vitro experiments. We argue that these constraints on rules may correspond to underlying steric constraints on the aggregation process. We find that monomer dominated growth of the areal aggregate is too slow to account for some observed doubling time-to-incubation time ratios inferred from data, and so consider aggregation dominated by relatively stable but non-infectious oligomeric intermediates. We compare a kinetic theory analysis of oligomeric aggregation to spatially explicit simulations of the process. We find that with suitable rules for misfolding of oligomers, possibly due to water exclusion by the surrounding aggregate, the resulting oligomeric aggregation model maps onto our previous monomer aggregation model. Therefore it can produce some of the same attractive features for the description of prion incubation time data. We propose experiments to test the oligomeric aggregation model.

description: The preference for cash-less transaction by Nigerians cannot be exaggerated, but despite its patronage, there exist limited access and utilization of the cash-less technologies among farmers in South-East Nigeria. The study analysed the determinants of rural farmers’ preference for cash-less transactions in Imo state, South-East Nigeria. Multi-stage sampling technique was employed in selection of 100 farmers for the study. The determinant of rural farmers’ preference for cash-less transactions in Imo State, was achieved using logit model. The result of the analysis showed that age (5%), gender (10%) education levels of the farmers (1%), user friendliness of technologies (5%), transaction charge (5%) and security of transactions (5%) were found to be the major determinants of farmers preference for cash-less transactions based on their levels of significance. Centred on the findings, the study recommended the strengthening of the use of cash-less transaction by farmers by providing a favourable financial environment through better orientation programs, so as to enable a smooth transition from a cash-based economy to cash-less economy.

Conditioned Taste Avoidance, Conditioned Place Preference and Hyperthermia Induced by the Second Generation 'Bath Salt' a-pyrrolidinopentiophenone (a-PVP)
Creators: name: Nelson, Katharine Hayley
Publisher: name: American University
Year: 2023

description: α-pyrrolidinopentiophenone (α-PVP) has been reported to be rewarding in a variety of pre-clinical models. Given that a number of drugs of abuse have both rewarding and aversive effects, the balance of which influences addiction potential, the present study examined the aversive properties of α-PVP by assessing its ability to induce taste avoidance. This assessment was made in a combined taste avoidance/place conditioning design that also allowed an evaluation of the relationship between α-PVP’s aversive and rewarding effects. Male Sprague-Dawley rats were exposed to a novel saccharin solution, injected with one of four doses of α-PVP (0, 0.3, 1.0 and 3.0 mg/kg) (IP) and placed on one side of a place conditioning apparatus. The next day, they were injected with vehicle, given access to water and placed on the other side. Following four conditioning cycles, saccharin avoidance and place preferences were then assessed. The effects of α-PVP on body temperature were also examined. α-PVP induced dose-dependent taste avoidance as well as significant increases in time spent on the drug-paired side (although this effect was not dependent on dose). α-PVP also induced dose- and time-dependent hyperthermia. α-PVP induced significant taste avoidance whose strength relative to the psychostimulants methylenedioxypyrovalerone (MDPV) and cocaine paralleled their relative binding to the dopamine transporter. Similar to other drugs of abuse, α-PVP has both aversive and rewarding effects. It will be important to assess how various experiential and subject variables impact these effects and their balance to predict abuse liability.

description: Objective(s): Silver nanostructures have gathered remarkable attention due to their applications in diverse fields. Researchers have recently demonstrated that bacterial spores are capable of reducing silver ions to elemental silver leading to formation of nanoparticles. Materials and Methods: In this study, spores of Bacillus subtilis and Geobacillus stearothermophilus were employed to produce silver nanoparticles (SNPs) from silver nitrate (AgNO3) through a green synthesis method. The production of SNPs by spores, heat inactivated spores (microcapsule) and spore extracts was monitored and compared at wavelengths between 300 to 700 nm. The biosynthesized SNPs by spore extracts were characterized and confirmed by XRD and TEM analyses. Results: UV Visible spectroscopy showed that the spore extracts were able to synthesize more SNPs than the other forms. The XRD pattern also revealed that the silver nanometals have crystalline structure with various topologies. The TEM micrographs showed polydispersed nanocrystal with dimensions ranging from 30 to 90 nm and 15 to 50 nm produced by spore extracts of B. subtilis and G. stearothermophilus, respectively. Moreover, these biologically synthesized nanoparticles exhibited antimicrobial activity against different opportunistic pathogens.Conclusion: This study suggests the bacterial spore extract as a safe, efficient, cost effective and eco-friendlymaterial for biosynthesis of SNPs.

description: This study aims to investigate the effect of main socioeconomic factors of technology adoption, with special reference to the role of assets specificity in farm management. The contribution of this study is largely empirical by testing some hypotheses in Algerian context. We investigate the determinants of technology asset control choices in the agricultural production in order to conclude on the constraints of farm extent and its implications for farm management and economic efficiency. Our main results assert that the technology asset control choice is determined by the farm size, organizational form, human capital, social status, and geographical location. These findings corroborate the existing theories and generate some empirical implications, leading to propose some directions for future research.

 Centris ehrhardti Schrottky, 1902b: 579. Junior synonym of C. dorsata (Friese 1904; Schrottky, 1904).
 Type data: Schrottky (1902b) described this species from a couple of males collected by Wilhelm Ehrhardt in Rincão, southeastern Brazil. Ehrhardt (1860‑1936) was a Guyana‑born German animal collector and an excellent taxidermist that operated in Brazil around the early 20 th century. He collected thousands of specimens of various animal groups, among them some amphibian, fish, mammal and insect species (Gutsche et al., 2007). Both syntypes are housed at MZSP being here designated the lectotype the one in best condition (Figs. 2A, B). The specimen has the following data label: 97250 [printed]\ 1360 [handwritten]\ ♂ [handwritten]. The paralectotype has the following data label: 97250 [printed]\ 1360 [handwritten]\ ♂ [handwritten].
 Comments: Schrottky (1902b) mentioned that the type specimens were collected on a Caesalpiniaceae, probably Cassia sp. According to the accession book at MZSP the number 1,360 refers to the following data: “ Brazil, São Paulo, Rincão, ii.1901, D. Ehrardt col” (Ramos et al., 2015). Centris dorsata has been recorded in Bolivia (Cochabamba department) and Brazil (Goiás, Mato Grosso do Sul, Minas Gerais, Paraná, Santa Catarina, and São Paulo states) (Moure et al., 2007).

description: Agriculture is characterized by a growing use of chemicals, such as fertilizers, pesticides and herbicides that are negatively affecting human health and the environment. Despite that, the Ethiopian government promotes the use of those chemicals in an attempt to increase yield and improve farmer’s livelihoods. On the other hand, environmental researchers argue that, equivalent yield can be obtained by using sustainable agricultural practices and produce safe food. Unfortunately, the “traditional” sustainable agricultural practices are being replaced by chemical intensive practices as the later is largely promoted. Therefore, it is important to trigger policy towards the promotion of “traditional” sustainable agricultural practices through research. This study, by using 299 randomly selected households from Eastern Ethiopia, unravels the factors that influence the use of crop rotation in Eastern Ethiopia. The results can serve policy makers by identifying the relevant variables and help them design successful intervention strategies. Based on the result, older age (older than 37 years), use of irrigation, distance to FTC, land size and farmers perception towards soil fertility are found to positively affect the decision to practice crop rotation. On the other hand, young age (younger than 37 years) and distance from market are found to hinder the decision of farmers to practice crop rotation. Sustainable agriculture can be brought back on track by creating a platform for older farmers to share their experiences with younger farmers and diverting some of the attention given to chemical fertilizers towards the “traditional” and sustainable practices.

Hc2(T) curves present a linear behavior towards low temperatures. Very high critical field values have been found, up to 24 T along the c-axis and 57 T in the basal plane not depending on the normal state resistivity values. In this paper, critical fields will be analyzed taking into account the multiband nature of MgB2; we will show that resistivity and upper critical fields can be ascribed to different scattering mechanisms.

description: Inspired by asynchronous cooperative Parrondo's games we introduce two new types of games in which all players simultaneously play game A or game B or a combination of these two games. These two types of games differ in the way a combination of games A and B is played. In the first type of synchronous games, all players simultaneously play the same game (either A or B), while in the second type players simultaneously play the game of their choice, i.e. A or B. We show that for these games, as in the case of asynchronous games, occurrence of the paradox depends on the number of players. An analytical result and an algorithm are derived for the probability distribution of these games.

title: 'Working at it': context, relationality and moral reasoning in narratives of fathering beyond couplehood
Creators: name: Philip, Georgia Clare
Publisher: name: The Open University
Year: 2010

description: This thesis supports earlier research suggesting that new contexts of fathering can bring 'transformative' experiences of care. At the same time, however, it also demonstrates the persistent 'pull' of a gendered model of parenting, which can normalise different and unequal levels of caring responsibility without disrupting a sense of the equal moral status of fathers and mothers. The research involved a qualitative study of previously resident, biological fathers' accounts of fathering after divorce or separation, focusing on 23 fathers who have maintained contact with their children over time and across households. The study entailed in depth interviews with fathers who were fathering in a range of contexts with a variety of caring arrangements in place. Taking a feminist perspective, the thesis presents post-couple fathering as a complex moral and relational process shaped deeply, though not straightforwardly, by gendered patterns of caring for children. It also makes particular use of the feminist ethics of care as an analytic framework and argues that this, together with the concept of relationality, can be used to think about autonomy, responsibility, gender and power in productive and insightful ways. The analysis showed that fathers perceive fathering beyond couplehood to occur in connection with others, and that it is particularly interconnected with mothers. It also revealed that the experience of post-couple fathering can produce an intensified focus on the quality of relationships and a heightened perception of the ongoing processes of moral and relational work involved. Further to this, three broader theoretical implications are raised: that a concept of fairness is in play during the relational and moral work of co-parenting; that a gendered moral space exists in which such work takes place, and that gendered patterns of care continue to act as a powerful framework in the process of renegotiating parental roles.

In this type of update, in each discrete timestep the particles are updated in a random sequence. Such an update is important for several applications, e.g. for certain models of pedestrian flow in two dimensions. For the ASEP with shuffled dynamics and a related truncated process exact results are obtained for deterministic motion (p=1). Since the shuffled dynamics is intrinsically stochastic, also this case is nontrivial. For the case of stochastic motion (0

We investigate properties of density field clusters and superclusters and compare the properties of these clusters and superclusters with those of Abell clusters, and superclusters found on the basis of Abell clusters. We found that clusters in a high-density environment have a luminosity a factor of 5 - 10 higher than in a low-density environment. Clusters and superclusters in the Northern slice of SDSS are much richer than those in the Southern slice.

description: Trade in agricultural commodity has significantly played a vital role in world’s economic growth and development. Drawing its strength from the agricultural industry, such important roles include contribution to quality food production, job creation, foreign exchange earnings, and industrial inputs. The objective of the article was to examine trade competitiveness and revealed comparative advantages of global tropical fruits and to measure the stability and duration of Balassa indices by applying Kaplan-Meier survival function and Markov transition probability matrices. Results reveal that Spain, Ecuador, and The United States were the main exporters of the examined tropical fruits in the periods evaluated, together giving 29% of all products exported. The top10 countries, therefore, consisted 60% of concentration, dominated by fresh or dried banana, including plantains, which constitutes more than 25% of trade, followed by fresh apples which represents more 18% of the total tropical fruits trade for all the periods. The Balassa indices, however, were the highest for Costa Rica and Ecuador. Typically, comparative advantages seem to diminish for most of the countries as manifested by the stability tests and mobility indices.

description: Previous studies on the role of FTAs in promoting members’ international trade have usually focused on FTA premium, ignoring the difference between selection effects – trade developments before the formation of FTAs – and “learning” effects – trade growth after the formation of FTAs. This paper considers this difference, using a large bilateral trade panel comprising data covering more than 50 years from 178 countries. South–South FTAs and North– South FTAs are most related to the selection effect while North–North FTAs have a significant “learning” effect.

By determining the parallax and proper motion of this object we find that the lens is an M dwarf star at a distance of 578(+65/-53)pc with a proper motion of 21.39 +/- 0.04 mas/yr. Based on the kinematics and location of this star it more likely to be part of the Galactic thick disk than thin disk population. We confirm that the microlensing event LMC-5 is a jerk-parallax event.

description: Insurance companies play a critical role in the financial markets by managing risk, offering financial protection, and contributing significantly to the overall economic system. In the capital market, they stand out due to their long-term investment strategies, risk management expertise, and their large-scale capital reserves. This article examines the key advantages of insurance companies in the capital market, focusing on their role in stabilizing markets, providing liquidity, and driving long-term investments.
title: Adult learners' experiences from learning age to Leitch: Implications of policy for local implementation and impact on learners
Creators: name: Pudney, Diana
Publisher: name: The Open University
Year: 2010

description: Centralised policy development seems 'dislocated' from policy implementation at a local level. The intent of nationally developed policy does not take sufficient account of local implementation needs and this, in turn, affects how a particular policy impacts on an individual or community. Since policy development is framed alongside a prevailing political environment (Hill, 2003), it is designed with broad national priorities in mind, often with identified target groups as its recipients. It is developed in a 'top down' way, based on what those with influence and power determine is the best way forward, to achieve the policy outcomes. The tendency is to regard all those within a particular target group as having similar needs, whereas in reality each individual has a unique set of circumstances relating to their life experience (Barton et al, 2006) as well as their physical situation, which can influence the impact a particular policy can have. The further away the detail of policy development is from its implementation sites, the less likely it is to be flexible enough to address a broad range of individual needs at a local level. In order to understand the relevance of local implementation for individuals' experience, with respect to the impact of Adult Skills policy, the study focuses on one particular aspect of Adult Skills policy i. e. Skills for Life. This was a priority area for New Labour policy development in the earliest days of their government The Skills for Life strategy, arising out of the recommendations of the Moser Report (DfEE, 1999) was conceived nationally through the Adult Basic Skills Strategy Unit but was implemented by local Learning and Skills Councils who developed individual Skills for Life strategies (L&R LSC, 2000) to meet the needs of their own areas. Over the past several years, as part of the process of implementing the government's Skills for Life strategy (DfEE, 2001), there have been major changes in the way that literacy, numeracy and language provision is delivered. The overall research question for the study is to establish if what individuals' tell us about their experiences of learning has implications for the way in which current Skills for Life policy is implemented at a local level and to what extent does increasing centralisation of policy development limit the ability of local implementation structures to meet the needs of individuals?

description: The sodium-cobalt oxide NaxCoO2+d is a promising candidate for thermoelectric applications since it may possess simultaneously large thermoelectric power and low resistivity. It is difficult to understand the simultaneous appearance of the two properties within the framework of conventional one-electron models. It has been suggested that the spin state of cobalt ions plays a crucially important role in enhancing the thermoelectric power. In order to study the relationship between the cobalt spin state and thermoelectric properties, NaxCoO2+d samples with precisely controlled sodium and oxygen contents are indispensable. Recently, we established an uncon-ventional sample-synthesis method that enables us to precisely control the Na content in NaxCoO2+d samples. In this article, we discuss the effects of sodium and oxygen nonstoichiometry on the thermoelectric properties of NaxCoO2+d.

description: Recent academic research suggests that teacher quality plays an important role in student achievement; however, empirical research on the efficacy of policies requiring teachers to obtain specific degrees is inconclusive, particularly in elementary education. This paper models a panel data production function with fixed effects using the Early Childhood Longitudinal Study (ECLS-K) to assess the relationship between different undergraduate and graduate majors and elementary student test scores. Specifically, we aim to discern if there is a difference in teacher efficacy within the different education related majors (e.g. early childhood education and elementary education) and between education and non-education related majors.
Clebsch-Gordan Coefficients for the Extended Quantum-Mechanical Poincaré Group and Angular Correlations of Decay Products
Creators: name: Harshman, Nathan
Publisher: name: American University
Year: 2023

description: This paper describes Clebsch-Gordan coefficients (CGCs) for unitary irreducible representations (UIRs) of the extended quantum mechanical Poincaré group $\pt$. `Extended' refers to the extension of the 10 parameter Lie group that is the Poincaré group by the discrete symmetries C, P, and T; `quantum mechanical' refers to the fact that we consider projective representations of the group. The particular set of CGCs presented here are applicable to the problem of the reduction of the direct product of two massive, unitary irreducible representations (UIRs) of $\pt$ with positive energy to irreducible components. Of the sixteen inequivalent representations of the discrete symmetries, the two standard representations with UCUP=±1 are considered. Also included in the analysis are additive internal quantum numbers specifying the superselection sector. As an example, these CGCs are applied to the decay process of the Υ(4S) meson.
ARE SHOCKS TO ALUMINIUM CONSUMPTION TRANSITORY OR PERMANENT?

description: This paper investigates whether shocks to aluminium consumption for 36 countries over the period 1967-2010 are transitory or permanent. A variety of time-series and panel data unit root tests are employed. The presence of structural breaks is taken into account when performing those tests. Following the Narayan-Popp univariate unit root test, aluminium consumption series for approximately 77.8% of countries is found to follow a non-stationary process. However unit root tests tend to have low power when the time span is relatively short and the results should be treated with some caution. Most of the panel unit root tests also point towards similar process. While these shocks can be transmitted to other economic sectors, past behaviours of aluminium consumption cannot be used for forecasting purposes. Mineral policies will have a permanent impact on the long-run trend of aluminium consumption.

Centris furcata friesei schrottky, 1902

description: Centris furcata friesei Schrottky, 1902
 Centris (Melanocentris) furcata var. friesei Schrottky, 1902a: 312. Junior synonym of C. obsoleta Lepeletier, 1841 (Friese, 1904).
 Type data: This variety was proposed based on an undetermined number of males collected in São Paulo state, southeastern Brazil. Moure et al. (2007) mentioned the existence of a holotype housed at MZSP but no primary types of this species were found in that collection (Ramos et al., 2015).The current condition and depository are unknown.
 Comments: According to the original description (Schrottky, 1902a) the type specimen was deposited in Schrottky’s own collection. Unfortunately, it is very probable that the type specimen is lost or destroyed, as well as a large number of his primary types (Rasmussen et al., 2009). Centris obsoleta is widely distributed in South America, being recorded in Argentina (Corrientes province), Brazil (Amazonas, Ceará, Mato Grosso, Pará, and São Paulo states), French Guiana, Paraguay and Venezuela (Mérida state) (Moure et al., 2007). Both sexes of this species have a strong variation in the coloration of the pubescence, which led different authors to describe subspecies, varieties or new species based on this character. Photographs of both sexes can be found in Vivallo & Zanella (2012).

description: Penile cancer (PC) is a rare neoplasm accounting for 2% of all cancers among men. With this highly lymphophilic tumor, inguinal node metastases are the most relevant prognostic factor and are associated with decreased survival. The PC evaluation presents a major challenge for therapeutic strategy. Here, we report the case of a 73-year-old man who was discovered with a process of the glans. The histopathological results concluded to be a penile squamous cell carcinoma (PSCC). An MRI scan showed a penile tumor process classified as T4Nx, with the presence of hypertrophic inguinal lymph nodes, which were not clearly suspicious. He was operated by total penectomy followed by perineostomy. The tumor was classified as pT3Nx. An 18F-fluorodeoxyglucose (118FDG) positron emission tomography / computed tomography (PET/CT) was requested to explore the metabolic pattern of these lymph nodes. 18FDG-PET/ CT demonstrated suspicious bilaterally hypermetabolic inguinal nodes, in favor of their metastatic nature and a non-specific hypermetabolism of the penile root. The decision of the urologist was to complete with an inguinal lymphadenectomy.

description: Spin transport at metallic interfaces is an essential ingredient of various spintronic device concepts, such as giant magnetoresistance, spin-transfer torque, and spin pumping. Spin-orbit coupling plays an important role in many such devices. In particular, spin current is partially absorbed at the interface due to spin-orbit coupling. We develop a general magnetoelectronic circuit theory and generalize the concept of the spin mixing conductance, accounting for various mechanisms responsible for spin-flip scattering. For the special case when exchange interactions dominate, we give a simple expression for the spin mixing conductance in terms of the contributions responsible for spin relaxation (i.e., spin memory loss), spin torque, and spin precession. The spin-memory loss parameter $δ$ is related to spin-flip transmission and reflection probabilities. There is no straightforward relation between spin torque and spin memory loss. We calculate the spin-flip scattering rates for N|N, F|N, F|F interfaces using the Landauer-Büttiker method within the linear muffin-tin orbital method and determine the values of $δ$ using circuit theory.
