description: Water quality and other co-benefits arise from greenhouse gas reduction efforts in agriculture, but there are tradeoffs with energy sector emissions. Greenhouse gas reductions by power plants also improve human health. Policy based on balancing benefits and costs must account for the co-effects in both the agriculture and energy sectors.
Landslides in the Charlie Lake map sheet, Fort St. John
Creators: name: Severin, Jordan M.
Publisher: name: University of British Columbia
Year: 2009

description: Many large, deep-seated landslides have occurred along the Peace River Valley and its steep-sided tributary valleys. These failures mostly occur within the Lower Cretaceous Shaftesbury Formation, a horizontally-bedded marine shale and the interglacial silt and clay beds in the Quaternary sequence. A detailed inventory of landslides was compiled in the Fort St. John area, using air photo interpretation and engineering-geological field mapping. The study area is on NTS Map Sheet 94A, comprising 14,000 km² of terrain. Practically all slope activity in the study area occurs on slopes of stream valleys. The observed landslides were separated into a series of failure types, involving bedrock, Quaternary deposits or both. The estimated areas of individual slide units range up to approximately 10,000 m² and volumes to 10,000,000 m². The result of the inventory is a digital landslide map at a 1:20,000 scale and a corresponding database of landslide characteristics. The main focus of the typological classification is the failure mechanism. The classification was reinforced by more detailed field study of selected type cases. There is a prevalence of multi-level failures, approximately 48%, utilizing weak surfaces at multiple levels. This type of failure occurs extensively both in the Quaternary sequence and the Cretaceous bedrock. An activity classification was implemented based on field observations and dated air photographs. The classification comprises landslides that are very active, active, of low activity, ancient, and anthropogenically modified. Results indicate that approximately 90% of the total length of valley slopes in the study area are involved in mass movements. Approximately 15% are occupied by very active or active landslides and 61.0% are Inactive - Dormant. Four areas were chosen to be studied in detail due to their accessibility from Fort St. John, diverse failure mechanisms, and diverse local stratigraphies. A generalized stratigraphic column and landslide model was produced for each area. These were generated from the detailed landslide investigations done.

description: We study the short-time dynamics of a degenerate Fermi gas positioned near a Feshbach resonance following an abrupt jump in the atomic interaction resulting from a change of external magnetic field. We investigate the dynamics of the condensate order parameter and pair wavefunction for a range of field strengths. When the abrupt jump is sufficient to span the BCS to BEC crossover, we show that the rigidity of the momentum distribution precludes any atom-molecule oscillations in the entrance channel dominated resonances observed in the 40K and 6Li. Focusing on material parameters tailored to the 40K Feshbach resonance system at 202.1 gauss, we comment on the integrity of the fast sweet projection technique as a vehicle to explore the condensed phase in the crossover region

description: Azimuthal distributions of pi+, K+ and K- mesons have been measured in Au+Au reactions at 1.5 AGeV and Ni+Ni reactions at 1.93 AGeV. In semi-central collisions at midrapidity, pi+ and K+ mesons are emitted preferentially perpendicular to the reaction plane in both collision systems. In contrast for K- mesons in Ni+Ni reactions an in-plane elliptic flow was observed for the first time at these incident energies.

description: A new saponin, 3-O-[α-ʟ-rhamnosyl-(1→3)-β-D-glucopyranosyl]-28-O-β-D-glucopyranosyl serjanic acid (Traphanoside GO1, 11) along with eleven compounds (1-10 and 12) were isolated from the aerial parts of Glinus oppositifolius. The structures of all isolates were elucidated by analyzing extensive 1 D- and 2 D-NMR and HR-ESI-MS, comparing with reported literature data. Compounds 7-8, 10-11, and 90% ethanol extract (GOE90) were evaluated for the inhibitory effect on PGE2 production from activated HepG2 cells. Among these, new compound 11 showed the most potent inhibitory activity by suppressing LPS-induced PGE2 production on the HepG2 cells.

description: Noise mitigation and reduction will be crucial for obtaining useful answers from near-term quantum computers. In this work, we present a general framework based on machine learning for reducing the impact of quantum hardware noise on quantum circuits. Our method, called noise-aware circuit learning (NACL), applies to circuits designed to compute a unitary transformation, prepare a set of quantum states, or estimate an observable of a many-qubit state. Given a task and a device model that captures information about the noise and connectivity of qubits in a device, NACL outputs an optimized circuit to accomplish this task in the presence of noise. It does so by minimizing a task-specific cost function over circuit depths and circuit structures. To demonstrate NACL, we construct circuits resilient to a fine-grained noise model derived from gate set tomography on a superconducting-circuit quantum device, for applications including quantum state overlap, quantum Fourier transform, and W-state preparation.

description: Within a hadron-string dynamical transport approach (HSD) we investigate the attenuation of high transverse momentum ($\pT$) hadrons as well as the suppression of 'near-side' and 'far-side' jets in $Au+Au$ collisions at invariant energies $\sqrt{s}$ = 200 GeV and $\sqrt{s}$ = 62.4 GeV in comparison to the data available from the Relativistic Heavy-Ion Collider (RHIC). From our transport studies we find that a significant part of the high $\pT$ hadron attenuation seen experimentally can be attributed to inelastic interactions of 'leading' pre-hadrons with the dense hadronic environment. In addition, we also show results of 'near-side' and 'far-side' angular correlations of high $\pT$ particles from Au+Au collisions at $\sqrt{s}$ = 200 GeV and $\sqrt{s}$ = 62.4 GeV within this (pre-)hadronic attenuation scenario. It turns out that the 'near-side' correlations are unaltered -- in accordance with experiment -- whereas the 'far-side' correlations are suppressed by up to $\sim$ 60% in central collisions. Since a much larger suppression is observed experimentally for these reactions in central reactions we conclude that there should be strong additional (and earlier) partonic interactions in the dense and possibly colored medium created in Au+Au collisions at RHIC.

description: Bioassay guided fractionation of the stem barks of Isolona cooperi led to the isolation of a new lactone, apoprunellelactone (APL, 1), and two known compounds, 5-[1-hydroxyhexyl]-2H-furan-2-one (2) and oleic acid (3). Their structures were elucidated by spectral analysis including MS, UV, IR, 1D and 2D-NMR spectroscopy. Evaluated for its antiprotozoal activities, APL (1) was found to be the most active on Leishmania donovani and L. major promastigotes with EC50 values of 16.3 and 8.2 µM, respectively. Against Trypanosoma brucei brucei trypomastigote forms, the activity of APL was moderated (MEC = 38.0 µM). Its hemisynthetic ester acetic derivative (1c) was 2-42 times more active than that of the APL and reference drugs, justifying further in vivo evaluation of the two compounds (1 and 1c) on Leishmania sp and Trypanosoma brucei brucei/mice models.

description: A NNLO analysis of certain logarithmic expansions, developed for precision studies of the evolution of the QCD parton distributions (pdf) at the Large Hadron Collider, is presented. We elaborate on their relations to all the solutions of the DGLAP equations that have been hitherto obtained from Mellin space, to which are equivalent. Exact expansions, equivalent to exact solutions of the equations, are constructed in the non-singlet sector. The algorithmic features of our approach are also emphasized, since this method allows to obtain numerical solutions of the evolution equations with the same accuracy of other methods, based on Mellin space, and of brute force methods, which solve the equations by finite differences. The implementation of our analysis allows to compare with existing benchmarks for the evolution of the pdf's, useful for applications at the LHC, and to extend them significantly in a systematic fashion, especially when solutions that retain logarithmic corrections only of a certain accuracy are searched for.

description: For a non-Hermitian Hamiltonian H possessing a real spectrum, we introduce a canonical orthonormal basis in which a previously introduced unitary mapping of H to a Hermitian Hamiltonian h takes a simple form. We use this basis to construct the observables O of the quantum mechanics based on H. In particular, we introduce pseudo-Hermitian position and momentum operators and a pseudo-Hermitian quantization scheme that relates the latter to the ordinary classical position and momentum observables. These allow us to address the problem of determining the conserved probability density and the underlying classical system for pseudo-Hermitian and in particular PT-symmetric quantum systems. As a concrete example we construct the Hermitian Hamiltonian h, the physical observables O, the localized states, and the conserved probability density for the non-Hermitian PT-symmetric square well. We achieve this by employing an appropriate perturbation scheme. For this system, we conduct a comprehensive study of both the kinematical and dynamical effects of the non-Hermiticity of the Hamiltonian on various physical quantities. In particular, we show that these effects are quantum mechanical in nature and diminish in the classical limit. Our results provide an objective assessment of the physical aspects of PT-symmetric quantum mechanics and clarify its relationship with both the conventional quantum mechanics and the classical mechanics.

Sedimentology, geochemistry and gas shale potential of the early Jurassic Nordegg member, northeastern British Columbia
Creators: name: Ross, Daniel John Kerridge
Publisher: name: University of British Columbia
Year: 2009

description: The Early Jurassic Nordegg Member in north-eastern British Columbia (NEBC) is composed of 25-30 m of organic-rich marine strata. The unit was deposited in a restricted basinal environment, west of a high standing carbonate platform. The Nordegg Member consists of four lithological facies: (A) a basal conglomeratic lag deposit; (B) a lower phosphatic marlstone that was deposited during highly productive conditions; (C) an overlying marlstone which represents an anoxic phase of sedimentation; and (D) an upper phosphatic mudstone reflecting a productive water column. Geochemical analysis reveals depositional conditions where high productivity is associated with enrichments of P and Fe, K, Ti, V, Cr and Zn and total organic carbon values (TOC) between 0-8 wt%, likely due to upwelling currents introduced nutrient-rich water increasing algal productivity during relative sea-level rise. The marlstone contains higher TOC (6-20 wt'%) and reduced concentrations of P, Fe, K, Ti V, Cr and Zn. The elevated TOC's and lack of productivity-proxying elements (e.g. P) infers organic matter incorporation into the sediment was primarily controlled by redox conditions when basin conditions were persistently anoxic. The TOC concentrations are a reflection of the depositional environment and have a strong influence on potential gas capacity. The TOC-rich samples have improved adsorption capacities compared to their organic-lean counterparts due to the highly microporous nature of organic matter to which the gas molecules physically adsorb to. Nordegg adsorbed gas capacities range from 0.05 cc/g to over 2 cc/g in organic-rich zones. The relationship between TOC and adsorption is complicated by other geologic factors including moisture. Moisture competes for adsorption sites with methane and blocks pores and pore-throats, reducing the transmissibility of the methane to the microporosity of the organic matter. Twenty to eighty percent of total gas storage is free gas (gas occupying open pores), ranging from 0.1 - 1.3 cc/g. Nordegg total gas-in-place ranges from 1 - 24 BCF/section. The greatest potential for gas shale production is to the south-west of the study area (93-P-5). TOC concentrations (up to 20 wt%), thickness, maturity and fracture-potential improve the gas shale potential in this region making it a prime gas exploration target.

description: Bianchi type V perfect fluid cosmological models are investigated with cosmological term $Λ$ varying with time. Using a generation technique (Camci {\it et al.}, 2001), it is shown that the Einstein's field equations are solvable for any arbitrary cosmic scale function. Solutions for particular forms of cosmic scale functions are also obtained. The cosmological constant is found to be decreasing function of time, which is supported by results from recent type Ia supernovae observations. Some physical aspects of the models are also discussed.

Structural dynamics in thermal-treatment of amorphous indium-oxide films

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: Thermally-treating amorphous indium-oxide films is used in various basic studies as a means of tuning the system disorder. In this process the resistance of a given sample decreases while its amorphous structure and chemical composition is preserved. The main effect of the process is an increase in the system density which in turn leads to improved interatomic overlap which is easily detected as improved conductivity. A similar effect has been observed in studies of other amorphous systems that were subjected to pressure. In the current work we show that the Raman spectra of amorphous indium-oxide change in response to thermal-treatment in a similar way as in pressure experiments performed on other disordered and amorphous systems. We present a study of how thermal-treatment changes the system dynamics by monitoring the resistance versus time of indium-oxide films following various stages of thermal-treatment. The time dependence of the sample resistance fits the stretched exponential law with parameters that change systematically with further annealing. Implication of these results to slow dynamics phenomena that are governed by the Kohlrausch's law are discussed.

description: We present a model-independent method to estimate the effects of short-distance constraints (SDCs) on the hadronic light-by-light contribution to the muon anomalous magnetic moment $a_μ^\text{HLbL}$. The relevant loop integral is evaluated using multi-parameter families of interpolation functions, which satisfy by construction all constraints derived from general principles and smoothly connect the low-energy region with those where either two or all three independent photon virtualities become large. In agreement with other recent model-based analyses, we find that the SDCs and thus the infinite towers of heavy intermediate states that are responsible for saturating them have a rather small effect on $a_μ^\text{HLbL}$. Taking as input the known ground-state pseudoscalar pole contributions, we obtain that the longitudinal SDCs increase $a_μ^\text{HLbL}$ by $(9.1\pm 5.0) \times 10^{-11}$, where the isovector channel is responsible for $(2.6\pm 1.5) \times 10^{-11}$. More precise estimates can be obtained with our method as soon as further accurate, model-independent information about important low-energy contributions from hadronic states with masses up to 1-2 GeV become available.

description: Using basic statistics and a simple gross margin analysis procedure, it is apparent that commercial table egg production in Lagos State is profitable. Under the same assumption and based on available statistics, the gross margin for a commercial table egg producer with 1000 laying birds has increased from N975,000:00 in 1998 to N1,050,000:00 in 2005, representing an increase of 7.7 percent. The demand for poultry products is expected to grow in view of increase in per capita income, increased awareness of the health implications of inadequate intake of protein in the human diet and the outbreak of avian influenza in Asia. Thus, increased production of table egg under the Presidential Initiative is sustainable and should be maintained.

description: We have revisited the search for carbon monoxide absorption features in transmission during the transit of the extrasolar planet HD 209458b. We acquired 1077 high resolution spectra at 2 microns using NIRSPEC on Keck II during three transits. Our sensitivity is sufficient to test the degree of CO absorption in the first overtone bands during transit, based on plausible models of the planetary atmosphere. We compare to theoretical tangent geometry absorption spectra, computed by adding height-invariant ad hoc temperature pertubations to the model atmosphere of Sudarsky et al., and by treating cloud height as an adjustable parameter. We do not detect CO absorption. Our analysis indicates a weakening similar to the case of sodium, suggesting that a general masking mechanism is at work in the planetary atmosphere. If this masking is provided by high clouds, our analysis defines the maximum cloud top pressure (i.e., minimum height) as a function of the model atmospheric temperature. For the relatively hot model used by Charbonneau et al. to interpret their sodium detection, our CO limit requires cloud tops at or above 3.3 mbar, and these clouds must be opaque at a wavelength of 2 microns. High clouds comprised of submicron-sized particles are already present in some models, but may not provide sufficient opacity to account for our CO result. Cooler model atmospheres, having smaller atmospheric scale heights and lower CO mixing ratios, may alleviate this problem to some extent. However, even models 500K cooler that the Sudarsky et al. model require clouds above the 100 mbar level to be consistent with our observations. Our null result therefore requires that clouds exist at an observable level in the atmosphere of HD 209458b, unless this planet is dramatically colder than current belief.

description: The current drive towards higher levels of commercialisation of cassava processing under the Presidential Initiative on Cassava requires that the scale of cassava processing be increased in Nigeria. Primary data obtained from 112 respondents selected from the 4 extension zones of Ogun State was used to examine the perception of effectiveness of innovations by cassava processors and the factors responsible for adoption of these innovations. The processors’ perception of effectiveness of cassava processing innovations was measured on a 5-point Likert-type scale containing 20 items. Most of the respondents (75%) are indifferent in their perception of the effectiveness of innovations in cassava processing. All the cassava processing innovations considered in this study are known to some respondents, but their levels of use and acquisition differ from one innovation or the other. There are no significant relationships between the processors’ perception of effectiveness of cassava processing innovations and adoption of cassava peeling machine, fortification of cassava with protein rich cereal and use of rotary dryer. There are however significant relationships between the cassava processors perception of the effectiveness of cassava processing innovations and adoption of hand driven grater; power driven grater, hydraulic press and iron frying pot. Also, there are significant relationships between the cassava processors perception of cassava processing innovations and the major product processed and the main occupation. The study concluded that it is important that cassava processors have access to trying and using cassava processing technologies under convenient arrangements to stimulate a positive attitude towards such innovations.

description: In a conversion efficiency study, 10 sawmills were selected out of the existing 44 in Abeokuta metropolis. For 5 days per week in each of the 10 sampled sawmills, the volumes of all the round logs to be converted each day were determined using Newton’s formula. At the end of the days work, the volumes of all lumbers converted were determined and were subtracted from those obtained in the morning, whatever is obtained was the volumes of wood wastes generated in each of the sampled sawmills. This study revealed that the mean conversion efficiency of the 10 selected mills was 56.05%. As a result, the total volume of wood waste generated per day by the 10 mills was approximately 52.00m3. In the entire Abeokuta metropolis 2288m3 of wood wastes will be generated per day. When carbonized, 381 tonnes of charcoal will be produced. In conclusion, it is suggested that enormous volume of wood waste generated in virtually all the sawmills in Abeokuta and indeed Nigeria are collected together and be used in the carbonization of charcoal as substitute for kerosene.

description: We apply a two-zone MHD model to the jet of M87. The model consists of an inner relativistic outflow, which is surrounded by a non-relativistic outer disk-wind. The outer disk-wind collimates very well through magnetic self-collimation and confines the inner relativistic jet into a narrow region around the rotation axis. Further, we show by example, that such models reproduce very accurately the observed opening angle of the M87 jet over a large range from the kiloparsec scale down to the sub-parsec scale.

Where do IceCube neutrinos come from? Hints from the diffuse gamma-ray flux

description: Despite the spectacular discovery of an astrophysical neutrino flux by IceCube in 2013, its origin remains a mystery. Whatever its sources, we expect the neutrino flux to be accompanied by a comparable gamma-ray flux. These photons should be degraded in energy by electromagnetic cascades and contribute to the diffuse GeV-TeV flux precisely measured by the Fermi-LAT. Population studies have also permitted to identify the main classes of contributors to this flux, which at the same time have not been associated with major neutrino sources in cross-correlation studies. These considerations allow one to set constraints on the origin and spectrum of the IceCube flux, in particular its low-energy part. We find that, even accounting for known systematic errors, the Fermi-LAT data exclude to at least 95% C.L. any extragalactic transparent source class, irrespective of its redshift evolution, if the neutrino spectrum extends to the TeV scale or below. If the neutrino spectrum has an abrupt cutoff at $\sim10$ TeV, barely compatible with current observations, the tension can be reduced, but this way out requires a significant modification to the current understanding of the origin of the diffuse extragalactic gamma-ray flux at GeV energies. In contrast, these considerations do not apply if a sizable fraction of IceCube data originates within the Galactic halo (a scenario however typically in tension with other constraints) or from a yet unidentified class of "opaque" extragalactic emitters, which do not let the high-energy gamma rays get out.

Long-range influence of manipulating disordered-insulators locally

description: Localization of wavefunctions is arguably the most familiar effect of disorder in quantum systems. It has been recently argued [[V. Khemani, R. Nandkishore, and S. L. Sondhi, Nature Physics, 11, 560 (2015)] that, contrary to naive expectation, manipulation of a localized-site in the disordered medium may produce a disturbance over a length-scale much larger than the localization-length $ξ$. Here we report on the observation of this nonlocal phenomenon in electronic transport experiment. Being a wave property, visibility of this effect hinges upon quantum-coherence, and its spatial-scale may be ultimately limited by the phase-coherent length of the disordered insulator. Evidence for quantum coherence in the Anderson-insulating phase may be obtained from magneto-resistance measurements which however are useful mainly in thin-films. The technique used in this work offers an empirical method to measure this fundamental aspect of Anderson-insulators even in relatively thick samples.

description: The development of rural areas impacts positively on per capita income and food production. The tier of government entrusted with the responsibility in Nigeria of developing the rural areas has not lived up to expectation in spite of the huge capital investment. This paper identified the root causes behind the failings of the local governments, reviews the performance of the fadama programme and draw on the reasons behind the successes of the latter as a basis for suggestions on how the local government system can be improved. Capacity building at the local level, increased demand for accountability, involvement of private and research bodies in local government activities should be encouraged to enhance rural development.

description: Previous studies have shown that some vegetables have the ability to absorb metals from soil. Since they are early maturity species, they possess the potential to be used as phytoremediating agents. Also, synthetic chelates have been found to induce lead desorption from soil matrix, thereby enhancing uptake into plant tissues. Therefore, a study was carried out to determine the potential of Amaranthus cruentus as a soil lead remediating plant. The experiment was carried out using a randomized block design. Soil samples were subjected to five levels of lead contamination namely control, 600ppm, 600ppm + EDTA, 1800ppm and 1800ppm + EDTA, each treatment had five replicates. Three plants each were carefully transplanted from nursery to experimental pots and grown for 32 days. Ethylenediaminetetra acetic(EDTA) (3.0 mmole EDTA/kg soil) was applied to EDTA amended treatment 8 days before harvesting. The result showed that EDTA has some effect on lead solubility in soil as well as lead absorption by A.cruentus. However, there were variable increases in lead uptake from the contaminated soil to the plants. Lead contamination did not have significant effect on growth and yield parameters of A cruentus. Since the transfer factor (TF) of the plant is greater than one, it may be a promising species for phytoremediation.

description: Space-based gravitational-wave detectors consist of a triangle of three spacecraft, which makes it possible to detect polarization modes of gravitational waves due to the motion of the detectors in space. In this paper we explore the ability of Taiji to detect the polarization modes in the parametrized post-Einsteinian framework. Assuming massive black hole binaries with the total mass of $M=4\times10^5\,M_{\odot}$ at redshift of $z=1$, we find that Taiji can measure the dipole and quadruple emission ($Δα_D/α_D$ and $Δα_Q/α_Q$) with the accuracy of up to $\sim 0.04\%$, with the fiducial value of $α_D=0.001$, the scalar transverse and longitudinal modes ($Δα_B$ and $Δα_L$) up to $\sim 0.01$, and the vector modes ($Δα_V$) up to $\sim 0.0005$.

description: This study examines the pattern of farm and off-farm labour supply among members of farming households in Yewa Division of Ogun state, Nigeria. The study was based on primary data obtained in a cross-sectional survey of 80 randomly selected household drawn by a three-stage sampling technique from 10 randomly selected farming communities in the study area. The data was obtained by personally administered questionnaires, and was focused on the socio-economic characteristics of the farming households, its labour allocation among various economic activities, agricultural production and income from all sources. The study data was analysed by descriptive and regression (Tobit and logit) techniques. The study found that income from non-farm sources accounts for as much as about half the farm households’ income. Only very few individuals and households depended solely on only one source of income (farm or non-farm); but, married women, and individuals that had their professional training in non-farm activities tend to supply more labour off-farm than an average household member in the sample. Furthermore, the study suggests that a major cause of poverty among rural farm households has been a result of their inadequate access to livestock production capital and skills, and small landholdings in crop production. This is because those households that were able to combine livestock production with arable crops farming were richer, on the average, than an average farming household that divested its labour into non-farm activities.

description: We propose a formalism for describing two-strand systems of a DNA type by means of soliton von Neumann equations, and illustrate how it works on a simple example exactly solvably by a Darboux transformation. The main idea behind the construction is the link between solutions of von Neumann equations and entangled states of systems consisting of two subsystems evolving in time in opposite directions. Such a time evolution has analogies in realistic DNA where the polymerazes move on leading and lagging strands in opposite directions.

description: This study analyzed the technological, financial and environmental viability of biomass charring technologies being adopted in Padali Community Forest of Lalitpur, Nepal. Earth pit, improved charring retort (ICR) and portable charring kiln (PCK) were evaluated based on efficiency and charcoal quality. The analysis revealed the best yield and efficiency of PCK. Overall charcoal quality characterized by fixed carbon content, volatile matter content, ash content, and the calorific value was also better with PCK. Calorific value, fixed carbon, volatile matter, ash content and mass yield of charcoal were significantly correlated with the peak charring temperature. The economic analysis revealed that PCK or earth pit kiln technology accompanied by bio-briquette production and sale was the most viable option based on Net Present Value. Occupational safety and health monitoring revealed an acceptable level of heat stress but respirable suspended particulate matter exposure was found a major problem. PCK was found to be the safest technology in terms of exposure of workers to respirable suspended particulate matter. Vegetation analysis showed that diversity, richness and regeneration status were satisfactory in both forest strata where biomass cleaning was done for charcoal production and where cleaning was not done. However, the comparison of forest structural diversity revealed notable differences in forest structural features in two strata.

description: We investigate cosmic-ray antiprotons emitted from the galactic primordial black holes in the Randall-Sundrum type-2 braneworld. The recent results of the BESS antiproton observation implies the existence of exotic primary sub-GeV antiprotons, one of whose most probable origin is PBHs in Our Galaxy. We show that the magnitude of antiproton flux from PBHs in the RS braneworld is proportional to negative power of the AdS radius, and immediately find that a large extra-dimension can relax upper-limits on the abundance of the Galactic PBHs. If actually there are more PBHs than the known upper-limit obtained in the pure 4D case, they set a lower bound on the size of the extra dimension above at least 10^{20} times 4D Planck-length to avoid inconsistency. On completion of the numerical studies, we show that these constraints on the AdS radius is comparable to those obtained from the diffuse photon background by some of the authors in the previous paper. Moreover, in the low accretion-rate case, only antiprotons can constrain the braneworld. We show that we will detect signatures of the braneworld as a difference between the flux of the antiprotons predicted in 4D and 5D by future observations in sub-GeV region with a few percent precision.

description: This study examines the occupational characteristics and technology options of capture fisheries in Ogun Waterside Local Government Area of Ogun State. Data were collected from respondents selected randomly from four fishing communities in the local government using questionnaires. Descriptive statistics were used to analyse the data. Most of the respondents are male, aged above 30 and had minimal education. Lagoon fishing is the most common and there was an inverse relationship between fishing water distance and frequency of fisher folk plying the route. Non-motorized fishing technologies were used by most of the respondents. The significant variables in the regression analyses are fixed production costs and high sea fishing. Recommendations centered on the need to improve on husbandry practices in the fishing sector in the study area and policy assistance in equipment procurement.

description: The study examined agricultural produce marketing in relation to gender empowerment in cross border along Nigeria-Niger border with the aim of identifying the socio-economic characteristics of the respondents, identifying characteristics of respondents’ cross border trade and the constraints faced by the respondents. One hundred respondents were selected with the use of systematic random technique. Primary data were collected from the respondents with the aid of interview guide structured in form of questionnaire and focus group discussion with other stakeholders like custom officials, as well as agriculture quarantine officers was performed. Univariate analysis like percentages, tables and pie charts and 3 point Likert scale were used to achieve the stated objectives. The study revealed that the respondents averagely made between N10,000 to N40,000 on monthly basis which helped in meeting family needs. About 78% indicated that one of their constraints was absence of modern financial institutions, inadequate storage facilities and about 82% signified that their major constraint was poor transport system while all affirmed that they experienced inadequate security among others. The study recommended that adequate security, global mass media facilities and adequate storage facilities should be provided to promote cross border trade.
