description: ABSTRACT Edible oil imports to Africa grew over 10% per year from 2006 to 2015, and accounted for 34% of the continent’s total growth in food imports over this period—the highest share of any food group. In the same period, several African countries experienced a boom in the local production and processing of oil-seeds. The combination of import growth and domestic production booms reveals a gap in the literature on the characteristics of edible oil demand in Africa. We begin to fill this gap by estimating own-price, cross-price, and expenditure elasticities of demand for palm, sunflower, and other edible oils in Tanzania. We apply a QUAIDS model to detailed household level data-focusing on palm and sunflower oil, because for the most part, palm oil is imported and sunflower is domestically produced. Our main finding is a surprisingly low level of substitution between the domestic and imported edible oils. Simulated budget shares from our estimates suggest that a 10% tariff increase on palm oil leads to less than a 0.06% change in the budget share of domestically produced sunflower oil. We identify other potential policy implications from our findings and highlight steps for further research.

description: Previously, Conway and Gainer (1987) postulated inversion of the third exons of vasotocin (AVT) and mesotocin (MT) genes in a frog, Xenopus laevis. Thus, sequencing analysis of a putative Xenopus AVT cDNA was conducted (clone J1). This clone had been previously obtained by screening a cDNA library with a synthetic probe based on published sequence data from a toad, Bufo japonicus. Screening and sequencing of the target cDNA was also repeated at much higher stringency. Also, amplification of the target DNA by polymerase chain reaction (PCR) was conducted. Clone J1 and one of the additional clones obtained were highly homologous to Xenopus 28S rRNA and to a Xenopus alpha-tubulin gene, respectively. Four other clones obtained had no apparent sequence homology to Bufo AVT or MT. Moreover, no specifically amplified fragments were obtained by the PCR study. This suggests that there might be significant variability in the AVT genes between Xenopus and Bufo species.

description: Recent in-depth analysis of current trends in Rwanda’s coffee sector, together with research findings from the Africa Great Lakes Coffee Support Program (AGLC) have revealed that low and stagnating production has placed Rwanda’s coffee sector in a vulnerable state (AGLC, 2016). Perennially low coffee prices (24 percent below others in the region) have resulted in low, often negative profits to farmers, discouraging them from investing in their plantations. Simply put, farmers have been left out of Rwanda’s “coffee renaissance” over the past 15 years and the consequences are now more apparent than ever. Many farmers report that losses in coffee have driven them to abandon their coffee trees and increasingly to uproot them in favor of other, more profitable crops. AGLC research shows that these trends are particularly acute among largeholder coffee farmers (those with 1000+ trees). These are farmers who are more highly commercialized, are highly responsive to cherry prices, and have other farming and off-farm options. They also own the majority (57 percent) of coffee trees in Rwanda (AGLC, 2016). Equally disconcerting is the finding that young farmers are choosing not to enter into coffee at all, often for the same reasons. They see clearly how their parents struggle to make a living in coffee and opt to produce other crops instead.

description: We study the C*-closure A of the algebra of all operators of order and class zero in Boutet de Monvel's calculus on a compact connected manifold X with non-empty boundary. We find short exact sequences in K-theory 0->K_i(C(X))->K_i(A/K)->K_{1-i}(C_0(T*X'))->0, i= 0,1, which split, where K denotes the compact ideal and T*X' the cotangent bundle of the interior of X. Using only simple K-theoretic arguments and the Atiyah-Singer Index Theorem, we show that the Fredholm index of an elliptic element in A is given as the composition of the topological index with mapping K_1(A/K)->K_0(C_0(T*X')) defined above. This relation was first established by Boutet de Monvel by different methods.

description: ABSTRACT Ghana is one of a few African countries where agricultural mechanization has recently undergone rapid development. Except for places in the forest zone where stumps are still an issue in fields, tractors used for plowing and maize shelling have been widely adopted even among small farmers. Medium- and large-scale farmers who own tractors provide the majority of mechanization services. Recognizing this fundamental fact is important for designing any effective mechanization policy, which should aim at the entire service market instead of targeting a selected group of service providers as beneficiaries. Tractor owners and operators are often discouraged from traveling long distances to plow only a few acres for individual small farmers, which becomes a considerable barrier for smallholders to access tractor services on time. This requires the government consider mechanisms to improve coordination among small farmers and to encourage Farmer Based Organizations (FBOs) to facilitate such coordination. The use of harrowing or second-plowing has been shown as a productivity-enhancing farming practice but it is currently under-demanded by farmers. A pilot program to address the coordination failures and to nudge small farmers to adopt harrowing services together can be considered.

description: Graph processes exhibit a temporal structure determined by the sequence index and and a spatial structure determined by the graph support. To learn from graph processes, an information processing architecture must then be able to exploit both underlying structures. We introduce Graph Recurrent Neural Networks (GRNNs) as a general learning framework that achieves this goal by leveraging the notion of a recurrent hidden state together with graph signal processing (GSP). In the GRNN, the number of learnable parameters is independent of the length of the sequence and of the size of the graph, guaranteeing scalability. We prove that GRNNs are permutation equivariant and that they are stable to perturbations of the underlying graph support. To address the problem of vanishing gradients, we also put forward gated GRNNs with three different gating mechanisms: time, node and edge gates. In numerical experiments involving both synthetic and real datasets, time-gated GRNNs are shown to improve upon GRNNs in problems with long term dependencies, while node and edge gates help encode long range dependencies present in the graph. The numerical results also show that GRNNs outperform GNNs and RNNs, highlighting the importance of taking both the temporal and graph structures of a graph process into account.

A second glance at SN 2002ap and the M74 field with XMM-Newton

description: We have re-observed the field of M74 in January 2003 with XMM-Newton, 11 months after the X-ray detection of SN 2002ap. From a comparison of the two XMM-Newton observations we obtain more accurate values for the X-ray luminosity and colours of the source five days after the event, and a limit on its decline rate. We compare its X-ray behaviour (prompt soft X-ray emission, relatively low luminosity) with that of other Type Ic SNe, and speculate that SN 2002ap may share some physical properties (low mass-loss rate and high-velocity stellar wind from the progenitor star) with the candidate hypernova/GRB progenitor SN 1998bw, but with a lower (non-relativistic) speed of the ejecta. We suggest that the X-ray emission observed in 2002 is likely to come from the radiatively-cooling reverse shock, at a temperature kT ~ 0.8 keV, and that this soft component was already detected 5 d after the event because the absorbing column density of the cool shell between the forward and reverse shocks was only ~ 10^{20} cm^{-2}, ie, the shell was optically thin in the soft X-ray band. The new XMM-Newton data also allowed us to continue monitoring two bright variable sources in M74 that had reached peak luminosities > 10^{39} erg s^{-1} in previous XMM-Newton and Chandra observations. Finally, we used two Chandra observations from 2001 to investigate the luminosity and colour distribution of the X-ray source population of M74, typical of moderately-active late-type spirals.

description: An experiment was designed to study the efficacy of three indigenous medicinal plants in single as well as mixture of them on gastro-intestinal nematode infection and growth of calves under rural situation. Twenty-five growing calves were divided into five groups (A, B, C, D & E) and randomly assigned to five anthelmintic treatments- Neem leaves, Atis leaves, Pineapple leaves, mixture of the three leaves and patent drug Albendazole, respectively. Faecal samples were examined immediately before treatment and on 7th, 14th, 21st and 28th day post-treatment. Live weight was measured prior to treatment and thereafter fortnightly until 60th day post-treatment. There were no significant differences in the efficacy (FECR %) values of the herbal anthelmintics on 7th day post-treatment, however, FECR% on 14th and 21st day post-treatment of Pineapple leaves (71.67&75.33) were significantly (P<0.01) higher than that of the others. In these periods of study, Neem leaves gave the second highest value (57.36&58.79) that was slightly higher than those of the mixture of leaves. On 28th day, Pineapple leaves as well as the leaf mixture gave significantly (P<0.05) higher values (60.45&59.08%, respectively) than those of the other leaves. All the efficacy values of individual leaves decreased after 21st day post-treatment while that of the mixture of leaves continued to increase up to 28th day. Although there were no significant differences in the mean values for the parameters, the highest live weight gain was observed in the Albendazole group and the lowest value was in the Atis group.

description: We present observations with XMM-Newton of M33 X-8, the ultraluminous X-ray source (L_{0.5-10 keV} ~ 2x10^39 erg/s) closest to the centre of the galaxy. The best-fit model is similar to the typical model of Galactic black holes in very high state. Comparison with previous observations indicates that the source is still in a very high state after about 20 years of observations. No state transition has been observed even during the present set of XMM-Newton observations. We estimate the lower limit of the mass of the black hole >6 M_sun, but with proper parameters taking into account different effects, the best estimate becomes 12 M_sun. Our analysis favours the hypothesis that M33 X-8 is a stellar mass black hole candidate, in agreement with the findings of other authors. In addition, we propose a different model where the high luminosity of the source is likely to be due to orientation effects of the accretion disc and anisotropies in the Comptonized emission.

description: Affordable, reliable, sustainable and modern energy consumption is a crucial goal of the Agenda 2030. To raise each citizen’s awareness for more effective energy consumptions, proper education is necessary. The classroom project GAIA (Green Awareness in Action) was designed to change energy consumption patterns to pursue green behaviour. The class-wise aim was to improve schools’ CO2-balance and to promote environmentally sustainable behaviour without impacting school life quality. Our target group were sixth graders (N = 132, M = 11.03, SD ± 0.23, 53.4% = girls) of one Greek school. To monitor the project’s effect, a pre- and post-test design was applied to measure environmental literacy regarding environmental knowledge, attitudes/values and behaviour. A regression analysis revealed that students with poor previous knowledge reached higher learning effects compared to those with good previous knowledge. Related to the environmental knowledge types, an ANCOVA analysis revealed a knowledge gain in action-related and effectiveness knowledge. The overall learning effect correlates positively with pro-environmental preference (high scores in preservation, low scores in utilisation) and negatively with weak pro-environmental preferences. Anthropocentric (utilitarian) preferences primarily focussing on nature exploitation have considerably decreased. The project illustrates how far individual behaviour can be targeted in green educational initiatives
Quantifying Convective Aggregation using the Tropical Moist Margin's Length

description: On small scales, the tropical atmosphere tends to be either moist or very dry. This defines two states that, on large scales, are separated by a sharp margin, well-identified by the anti-mode of the bimodal tropical column water vapor distribution. Despite recent progress in understanding physical processes governing the spatio-temporal variability of tropical water vapor, the behavior of this margin remains elusive, and we lack a simple framework to understand the bimodality of tropical water vapor in observations. Motivated by the success of coarsening theory in explaining bimodal distributions, we leverage its methodology to relate the moisture field's spatial organization to its time-evolution. This results in a new diagnostic framework for the bimodality of tropical water vapor, from which we argue that the length of the margin separating moist from dry regions should evolve towards a minimum in equilibrium. As the spatial organization of moisture is closely related to the organization of tropical convection, we hereby introduce a new organization index (BLW) measuring the ratio of the margin's length to the circumference of a well-defined equilibrium shape. Using BLW, we assess the evolution of self-aggregation in idealized cloud-resolving simulations of radiative-convective equilibrium and contrast it to the time-evolution of the Atlantic Inter-Tropical Convergence Zone (ITCZ) in the ERA5 meteorological re-analysis product. We find that BLW successfully captures aspects of convective organization ignored by more traditional metrics, while offering a new perpective on the seasonal cycle of convective organization in the Atlantic ITCZ.

description: A total of about 387 data were collected from three regions of Bangladesh namely Chandanais, Chittagong; Dhamrai, Dhaka and Jhinaigati, Sherpur to observe the variability in production of indigenous village chicken of Bangladesh. Among the regions, the highest average body weight of birds was found in Chandanais (1357.81± 43.02g) and lowest in Dhamrai (906.64 ±12.25g). In case of egg production, the highest average egg production of hen was found in Chandanais (14.24±0.67 eggs per clutch) and lowest in Dhamrai (12.54 ±0.21 eggs per clutch). The regional difference in body weight and egg production performance was highly significant (p<0.001). On the other hand, plumage color (Black, blackish red, blackish white, blackish yellow, yellow, whitish yellow, reddish yellow, white, blackish brown, brown, grey, reddish white, brownish yellow and brownish red) wise body weight of birds varied significantly (p<0.001) and difference in egg production was also significant (p<0.05). Existing variation indicates that village community based pure breeding programme may help to improve indigenous chicken of Bangladesh.
The possible role of thrombin in the elimination of transient ipsilateral retinotectal projections in the chick
Creators: name: Robinson, Andrea Michelle
Publisher: name: American University
Year: 2023

description: During development, chick ipsilateral retinotectal synapses appear at ages E10/E11, peak at E12, and are nearly obliterated by E16. These ipsilateral connection changes are part of normal nervous system developmental refinement processes. Thrombin appears active during in vitro neuromuscular refinement. Using techniques to culture embryonic chickens, protease inhibitors were administered to inhibit thrombin action and potentially "maintain" ipsilateral connections. Leupeptin (1 $\mu$M), a serine and cysteine protease inhibitor, caused no statistically significant change in E16 ipsilateral counts. The problems encountered during experimentation were fungal chick infection, chick death, and dye-labelling artefacts on slides. Protocol changes increased data output and experimental productivity. Antithrombin experiment results were inconclusive; questions involving blood brain barrier permeability are unanswered. Further work on thrombin action in chick ipsilateral elimination may prove fruitful since it is uncertain as to whether or not the blood brain barrier has hindered protease inhibitor effects in these experiments.

description: The growth performance of Spirulina platensis was studied in various concentrations viz., 0.3, 0.4 and 0.5 g/L of papaya skin powder medium (PSPM) and Kosaric Medium (KM) in the laboratory for three months. Each trial was carried out for a period of 12 days with three replications. The growth rate of S. platensis was found to vary in different media. The initial cell weight of S. platensis was 4.0 mg/L which attained a maximum weight of 0.720 g/L in KM followed by 0.693, 0.578 and 0.430 g/L in 0.3, 0.4 and 0.5 g/L of PSPM, respectively on 8th day of culture. Similar trend was observed in the case of chlorophyll a content of S. platensis. The proximate composition of papaya skin powder was analyzed and found that the amount of protein was 20.25%, lipid 3.85%, ash 9.31%, NFE 50.49% and moisture 16.10%. The result indicated that the growth rate of S. platensis was significantly (p<0.01) higher in 0.3 g/L concentration of PSPM than other concentrations of PSPM. The physico-chemical parameters viz., temperature (30.06 °C), light intensity (2110 lux/m2/s), dissolved oxygen (4.8 mg/L), pH (12.08), nitratenitrogen (3.29 mg/L), phosphate-phosphorus (1.97 mg/L), and nitrite-nitrogen (0.063 mg/L) were observed in optimum levels.

description: The ultimate goal of transfer learning is to reduce labeled data requirements by exploiting a pre-existing embedding model trained for different datasets or tasks. The visual and language communities have established benchmarks to compare embeddings, but the speech community has yet to do so. This paper proposes a benchmark for comparing speech representations on non-semantic tasks, and proposes a representation based on an unsupervised triplet-loss objective. The proposed representation outperforms other representations on the benchmark, and even exceeds state-of-the-art performance on a number of transfer learning tasks. The embedding is trained on a publicly available dataset, and it is tested on a variety of low-resource downstream tasks, including personalization tasks and medical domain. The benchmark, models, and evaluation code are publicly released.

description: We calculate the temperature dependence of the fluorescence Stokes shift and the fluorescence decay time in linear Frenkel exciton systems resulting from the thermal redistribution of exciton population over the band states. The following factors, relevant to common experimental conditions, are accounted for in our kinetic model: (weak) localization of the exciton states by static disorder, coupling of the localized excitons to vibrations in the host medium, a possible non-equilibrium of the subsystem of localized Frenkel excitons on the time scale of the emission process, and different excitation conditions (resonant or non resonant). A Pauli master equation, with microscopically calculated transition rates, is used to describe the redistribution of the exciton population over the manifold of localized exciton states. We find a counterintuitive non-monotonic temperature dependence of the Stokes shift. In addition, we show that depending on experimental conditions, the observed fluorescence decay time may be determined by vibration-induced intra-band relaxation, rather than radiative relaxation to the ground state. The model considered has relevance to a wide variety of materials, such as linear molecular aggregates, conjugated polymers, and polysilanes.

The chemistry in the two aureoles also generally shows similar trends although original sedimentary variations across the Aberfoyle slates severely affected the behaviour of most elements. In the Cashel thermal aureole, it is shown that the elements which are commonly enriched in acidic rocks viz : Si, K, Na, P, U, Rb, Ba, Th and to some extent Zr were removed from the envelope hornfelses, those commonly enriched in mafic rocks viz: Mg, Fe, Cr, Ni, and Co were enriched whereas those elements which are intermediate in character viz: Al, Ti, Ca, and Sr were both enriched and removed. Eu was removed much less significantly compared to the other REE thus giving increasing positive Eu anomalies as the degree of hornfelsing and partial melting rise. In the Comrie thermal aureole, the sedimentary variations mention ed above strongly affected the variation of elements during hornfelsing and partial melting of the Aberfoyle Slates, although the available evidence suggests similar trends to the Cashel thermal aureole. Mineralogical, chemical and Sr isotope evidence show that the Cashel trondhjemite migmatite leucosomes were produced at degrees of partial melting of between 15 and 30% and their chemical compositions compare reasonably well with the melts derived from the metasediments as calculated using the strongly compatible elements Cr, Ni and Co. This conclusively indicates they were derived from the metasediments and so does the Cashel microgranite sill. The Comrie leucosomes are dominantly late stage magmatic injections although the melts, which were probably near eutectic in composition in part, derive from the partially melted metasediments. The elements as deduced from the Cashel, and probably also the Comrie and Cortlandt, New York aureoles, were fractionated into the melts in the following order :Si>K>Na>Ca>Mn>AI>Fe>Mg and Rb>Ba>Sr>Ga>Cr, Ni, Co. This calculated order of fractionation of elements, which is the opposite to magmatic crystallization, provides a unique picture on the mode of interaction of mantle derived magmas with the earth's crust and therefore gives clear explanation on how S-type granites and other crustally contaminated rock types are produced, especially as the melts derived from both the Cashel and Comrie hornfelses are S-type melts as defined by Chappell and White (1974).

description: Impact of carp stocking on the yield and biodiversity of non-stocked indigenous fish species in six selected oxbow lakes (baors) located in southwestern part of Bangladesh has been reported in this article. The stocking densities were 4636, 333, 3514, 1803, 5993 and 2404 fingerlings/ha in Benipur, Kayetpara, Saster, Bahadurpur, Nasti, and Bukbhara baor, respectively. The yield of non-stocked indigenous fish species (NIFS) in the studied baors varied from 0.52-134.56 kg/ha during the study period. The yield of stocked carps in the studied baors varied from 83-1027 kg/ha/yr during 2001-2002. Species abundance was different in the six selected baors. A maximum of 32 species were recorded in Bahadurpur baor while 25 in Bukhara, 16 in Kayetpara, 13 in Benipur, 9 in Nasti and 8 in Saster baor.
Comparison of heat shock cognate protein-72 mRNA expression in young and adult gerbil brains following transient global ischemia

description: Distributions of heat shock cognate-72 protein (HSC72) mRNA were investigated by in situ hybridization in the hippocampus of young and adult male Mongolian gerbils following 15 min of global cerebral ischemia. The vulnerable CA1 region showed maximal expression of mRNA after 48 h of reperfusion in both young and adult animals. Minimal changes in mRNA expression were observed in adult animals prior to 48 h of reperfusion with regard to control values. In contrast, young animals showed a gradual increase in mRNA hybridization following the same amount of reperfusion. Neuronal staining in the hippocampus of both experimental groups revealed few pathological changes prior to 48 h of reperfusion. At 48 h, cellular injury was apparent in the adult CA1 region, where as few pathological changes occurred in the same area of young animals. These results suggest a possible age-dependent correlation between HSC72 mRNA induction and neuronal survivability in young and adult gerbils.

description: An experiment was carried out to evaluate the profitability of rice production using a drum seeder developed in the department of Farm Power and Machinery, Bangladesh Agricultural University, during transplant aman seasons July-December, 2004 at Mymensingh. Three planting methods viz., direct seeding with drum seeder, broadcasting and transplanting were used in the experiment. The treatments were replicated three times in Randomized complete block design. The results revealed that all the treatments under the study had significant influence on the yield and yield attributes of rice. Drum seeded crop produced the highest plant height 101.49 cm, panicle length 22.84 cm, leaf len9th 52.39 cm, root length 11.11 cm, number of panicles 382.61 m-2, number of effective tillers 8.55 hill-I, number of total tillers 9.6 hill-1, wt. of straw 29.84gm hill-1, straw yield 6882kg ha-1, harvest index 44.42 %, and biological yield 12902kg ha-1. Crop in broadcasting method produced the highest number of noneffective tillers 2.3 hill-1. Crop established with a drum seeder resulted in higher grain yield 5634 kg ha-1, which was at par with transplanting 5213 kg ha-1 and superior over broadcasting 3505 kg ha-1. Not only the yield, but also the highest net revenue of Tk 27541 ha-1 with benefit cost ratio of 1.92 was also recorded by the drum seeding. The cost of crop establishment in transplanting method was 1.71 times higher than that from seeding by the drum seeder. It might be concluded that the drum seeder technique would be more profitable than transplanting method of rice production in Bangladesh.

description: We present the results of a wide-area mapping of the far-infrared continuum emission toward the Orion complex by using a Japanese balloon-borne telescope. The 155-um continuum emission was detected over a region of 1.5 deg^2 around the KL nebula with 3' resolution similar to that of the IRAS 100-um map. Assuming a single-temperature model of the thermal equilibrium dust, maps of the temperature and the optical depth were derived from the 155 um intensity and the IRAS 100 um intensity. The derived dust temperature is 5 - 15 K lower and the derived dust optical thickness were derived from the 155-um intensity and the IRAS 100-um intensity. The derived dust temperature is 5 - 15 K lower and the derived dust optical depth is 5 - 300 times larger than those derived from the IRAS 60 and 100-um intensities due to the significant contribution of the statistically heated very small grains to the IRAS 60-um intensity. The optical-thickness distribution shows a filamentary dust ridge that has a 1.5 degrees extent in the north - south direction and well resembles the Integral-Shaped Filament (ISF) molecular gas distribution. The gas-to-dust ratio derived from the CO molecular gas distribution along the ISF is in the range 30 - 200, which may be interpreted as being an effect of CO depletion due to the photodissociation and/or the freezing on dust grains.

description: We construct the $\mathcal{N} = 1$ supersymmetric extension of the generalized Kerr-Schild ansatz in the flux formulation of Double Field Theory. We show that this ansatz is compatible with $\mathcal{N} = 1$ supersymmetry as long as it is not written in terms of generalized null vectors. Supersymmetric consistency is obtained through a set of conditions that imply linearity of the generalized gravitino perturbation and unrestricted perturbations of the generalized background dilaton and dilatino. As a final step we parametrize the previous theory in terms of the field content of the low energy effective $10$-dimensional heterotic supergravity and we find that the perturbation of the $10$-dimensional vielbein, Kalb-Ramond field and gravitino can be written in terms of a pair of null vectors, as expected.

description: Neonatal (P2) rats received a unilateral olfactory bulbectomy and were later trained in an olfactometer to detect ethyl acetate and chocolate chip cookie odor. After removal of the remaining olfactory bulb, rats were tested for retention and trained to detect cineole, gardenia perfume and amyl acetate. Rats with an intact olfactory bulb served as controls. Anterograde transport of horseradish peroxidase applied to the olfactory epithelium was used to assess forebrain projections of sensory neurons. Four experimental rats with connections from the olfactory epithelium to the olfactory peduncle or olfactory cortex performed about as well as controls on odor detection tasks. Olfactory connections of the remaining seven rats appeared to be restricted to frontal cortex, and these rats were anosmic. Results indicate that, in the absence of the olfactory bulbs, projections from olfactory epithelium, to olfactory peduncle or to olfactory cortex can support detection of vapor stimuli.
