 Diagnosis
 Omorgus badeni is similar in appearance to O. borrei. It can be distinguished from the latter by the presence of round shiny black tubercles on the odd-numbered elytral costae. Omorgus borrei have the odd-numbered costae marked by distinct flat lustrous areas. For a more detailed treatment of O. badeni, see Scholtz (1990).
 Geographic distribution
 In Brazil, Omorgus badeni occurs in the BA, CE, PE and RN states (Caatinga biome) (Figure 9).

description: The usefulness of the spectral function S in the process 3He(e,e'N) has been investigated in a kinematical regime constrained by the conditions that the three-nucleon center-of-mass energy is less than 150 MeV and the magnitude of the three-momentum transfer smaller than 600 MeV/c. Results based on a full treatment of the final state interaction are compared to the spectral function approximation. In the case of proton knockout in the direction of the photon kinematical conditions have been identified where both response functions, RL and RT, can be well approximated by S. These conditions occur for certain low missing momenta and missing energies but not in all cases. So care is required. In case of neutron knockout only RT is a candidate for an approximate treatment by S. In the case of RL the concept of using S is not valid in the studied kinematical regime. This does not exclude the possibility that beyond that regime it might be useful. Possible applications using S for the extraction of electromagnetic form factors of the nucleons are pointed out.

description: An objective interpersonal comparison of wellbeing requires that people’s capabilities are considered. This paper operationalizes Sen’s capability concept in maize-based farming systems and assess how it influences farmers’ participation in the Planting for Food and Jobs programme in the Bunkpurugu-Yunyoo District of the Northern region, Ghana. We used data from 314 households through multi-stage sampling procedure. Capability was quantified using factor analysis, while its determinants were identified through multiple linear regression analysis. Afterwards, an instrumental variable probit model was used to examine the effect of capability on programme participation. The factor analysis results reveal two attributes of capability, which were labeled as human capability and institutional capability. These capability attributes are significantly enhanced by availability of markets and good roads. The probit model results provide substantial evidence that both attributes of capability influence farmers’ participation in the Planting for Food and Jobs programme. Specifically, a one standardized unit increase in institutional capability increases the probability of participation by 10.45%. The findings indicate that, for effective participation in agricultural interventions, farmers’ capabilities need to be enhanced. This could be achieved through the provision of, and/or improvement in infrastructure, including roads and markets in remote production centers.

description: Empirical literature and policy documents always capture access to credit as one of the most important determinants of successful agricultural production in Ghana and elsewhere in the developing world, particularly Africa. It is often argued that access to credit allows farmers to invest confidently in their agricultural production activities leading to increased productivity, which consequently is able to urge them out of poverty. The extent to which these long held views and narratives are true in modern Ghana is yet to be ascertained. This paper therefore uses mixed methods to ascertain whether or not farmers accord the same level of importance to credit in their agricultural production as being perceived by policy makers, development practitioners and researchers. Thus, the paper analyzed the importance of credit relative to other factors of agricultural production of farm households in Ghana. Multistage sampling was employed in the selection of sub-study areas and research participants across the three main ecological zones (i.e. coastal, forest and savannah) of Ghana. The results indicated that the five most important factors of agricultural production, in the view of farmers are, in descending order, equity finance, technological change, farm implements, credit finance and labor. This result show that in relative terms, access to credit is the fourth most important, which means that its importance has over the years been exaggerated in the empirical literature and by policy makers, implementers and development practitioners. The implication of this is that policies that aim to improve agricultural production and promote transformation of Ghana’s agricultural sector must focus on helping farmers accumulate equity capital, provide them with the requisite technologies and mechanized farm equipment before thinking of credit financing.

description: Many consumers are familiar with herbs but are consumers familiar with products produced out of herbs? Even though WHO (2001) states that in Africa, approximately 80% of the population takes some form of herbal remedies; the type of herbal product used for the herbal remedy is unknown. Investors in the herbal industry are aware of the industry’s lucrativeness but the target market and product type to concentrate on become a problem. It is confusing how a lucrative business attracts less investors. It would be interesting to investigate into consumers’ familiarity and use of natural health products since it has the potential of creating jobs in the agribusiness sector. Kumasi and Accra metropolitan were the target area because they are representative of Ghana due to high migration of people from the various regions to these metropolitans. The two-stage sampling technique was used with a total sample size of three hundred and eighty-five (385). More than twice of consumers are familiar and have used herbal medicine than herbal food supplement. For herbal medicine, herbal mixture and herbal cream is widely used than herbal capsules. The researcher recommends that investors and entrepreneurs should focus more on herbal medicine than herbal food supplement since many consumers are familiar and have used herbal medicine. Lastly, the herbal industry should target the older generation rather than the younger generation.

description: Climate variability (CCV) presents an additional challenge to the agricultural sector and society’s livelihood due its persistent low rainfall and high temperatures. Particularly to face the brunt of climate variability are women smallholder farmers who depend on agricultural production and have limited natural resources to enable them respond to the changing climate. The aim of the study was to investigate smallholder women farmers’ off-farm adaptation strategies to climate variability in the Wa West district in the Upper West region. The study adopted a case study designed method with a population of 187 smallholder farmers. Purposive and multi-stage probability sampling were used to select the communities and women respondents for the study. Questionnaires and interviews were used and data collected was analyzed descriptively using Statistical Package for Social Science (SPSS).The results of the study indicated that, smallholder women farmers have adopted mixed off-farm adaptation strategies to climate variability. The study recommends a comprehensive and an integrated adaptation program for the agricultural sector with special focus on smallholder women farmers to include education and training of women on diseases and pest control and prevention, access to credit and value chain development for agro-processing business, and access to climate variability information.

description: Topological invariants characterising filled Bloch bands attract enormous interest, underpinning electronic topological insulators and analogous artificial lattices for Bose-Einstein condensates, photons, and acoustic waves. In the latter bosonic systems there is no Fermi exclusion principle to enforce uniform band filling, which makes measurement of their bulk topological invariants challenging. Here we show how to achieve controllable filling of bosonic bands using leaky photonic lattices. Leaky photonic lattices host transitions between bound and radiative modes at a critical energy, which plays a role analogous to the electronic Fermi level. Tuning this effective Fermi level into a band gap results in disorder-robust dynamical quantization of bulk topological invariants such as the Chern number. Our findings establish leaky lattices as a novel and highly flexible platform for exploring topological and non-Hermitian wave physics.

description: The Government of Ghana together with donor agencies has in many years paid attention to the agricultural sector with special emphasis on staple crops especially root and tuber crops. Sweetpotato has particularly received a lot of research funding over many years to develop many varieties which have been disseminated. However, many farmers still depend on traditional varieties. The aim of the study was to determine the role of awareness in adoption of improved sweetpotato varieties. By using a cross- sectional data collected from 526 farmers and employing binary logit model, an analysis of factors influencing adoption of improved sweetpotato varieties adoption was evaluated. The results revealed that sixty five percent of farmers had adopted improved sweetpotato varieties. Eighty five percent of farmers were aware of the improved sweetpotato varieties. Empirical results revealed that apart from the standard farm and farmer characteristics and institutional factors that influenced adoption, awareness positively and significantly influenced adoption of improved sweetpotato varieties. Awareness creation and education of the improved varieties will encourage adoption. Government and donor agencies should support the extension services in terms of resources to conduct more demonstrations to create awareness. Furthermore media could be engaged to support dissemination of improved varieties.

description: To achieve improved production levels, farmers need to master new skills and learn to manage and manipulate relevant agricultural information. Information is one of the basic human needs after air, water, food, and shelter and thus could be said to be one of the basic necessities of life. Therefore, how far farmers progress in their farm enterprises depends largely on the availability of and access to accurate and reliable information. This study is to assess dissemination path ways of improved technologies of cassava cultivation and the impact of adoption of these technologies on farm household’s yields, incomes, and food security. With the use of a concurrent mixed method approach, employed in the setting of Nsuta and Wenchi, selected districts in Ghana, the study found that farmers were more eager about accessing agricultural information from various dissemination pathways; predominantly extension agents, farmer fields, radio and demonstrations within their localities. However, access to agricultural information by the cassava farmers in this study setting were constrained by time, cost and cultural barriers. Therefore, the study recommends a sound communication strategy to effectively and quickly disseminate the latest agricultural technologies to farming communities and aid individual farmers in adopting them.

We find that the asymptotic expansion for the resolvent in the general case presents powers of $λ$ which depend on the singularity, and can take even irrational values. The consequences for the pole structure of the corresponding $ζ$ and $η$-functions are also discussed.

description: This report quantifies relationships between reserve activities and State grain prices for corn, sorghum, and wheat and discusses the farmer-owned reserve release mechanisms and some alternatives to the current release mechanism. Release of FOR stocks had little or no measurable effect on lowering State-U.S. monthly grain price differentials for most of the States studied. Tne 5-day average adjusted prices based on a production-weighted average and a reserve-weighted average were shown to differ from the price series based on a simple average (the current method) only by a few cents. Setting release Prices in eacn State by adjusting the national release price by the normal State-U.S. grain price differentials would narrow the differential for States where an abnormally wide differential has been the case during release status.

description: Most current clustering based anomaly detection methods use scoring schema and thresholds to classify anomalies. These methods are often tailored to target specific data sets with "known" number of clusters. The paper provides a streaming clustering and anomaly detection algorithm that does not require strict arbitrary thresholds on the anomaly scores or knowledge of the number of clusters while performing probabilistic anomaly detection and clustering simultaneously. This ensures that the cluster formation is not impacted by the presence of anomalous data, thereby leading to more reliable definition of "normal vs abnormal" behavior. The motivations behind developing the INCAD model and the path that leads to the streaming model is discussed.

description: Let X_n=(x_{ij}) be an n by p data matrix, where the n rows form a random sample of size n from a certain p-dimensional population distribution. Let R_n=(ρ_{ij}) be the p\times p sample correlation matrix of X_n; that is, the entry ρ_{ij} is the usual Pearson's correlation coefficient between the ith column of X_n and jth column of X_n. For contemporary data both n and p are large. When the population is a multivariate normal we study the test that H_0: the p variates of the population are uncorrelated. A test statistic is chosen as L_n=max_{i\ne j}|ρ_{ij}|. The asymptotic distribution of L_n is derived by using the Chen-Stein Poisson approximation method. Similar results for the non-Gaussian case are also derived.

description: In 1980 irrigation, drainage, and conservation assets serving U.S. agriculture amounted to $44.3 billion (1977 dollars). These assets, called natural resource capital (NRC), represented about 25 percent of all depreciable nonland business capital in agriculture. Producers' durable equipment other than specialized irrigation equipment accounted for 43 percent of NRC. Nonresidential farm service structures made up the remaining 32 percent of all depreciable business capital. Farm homes, not an element of farm business capital, were worth $38.5 billion, or 13 percent less than the value of NRC on and off farms. In 1980 the onfarm and off farm values of NRC facilities and associated equipment were almost equal, at $22.1 and $22.3 billion, respectively. The onfarm component represented about 14 percent of all depreciable (nonland) business capital on farms.

description: To evaluate the often stated proposition that agricultural protectionism has reduced market access for agricultural exports worldwide, this report examines market penetration of importing country markets by exporters of corn, soybeans, beef and veal, tobacco, wheat, rice, and cotton in 1970-82.' Results indicate that, with the exception of the European Community's variable import levy on corn, soybeans, corn, and cotton markets are relatively open and that protection for beef and veal has been limited primarily to the developed countries. Lower rates of market penetration growth by exporters of wheat and rice are indicative of higher levels of protection and producer support in importing country markets. Trade negotiations to increase market access for U.S. agricultural exports should therefore concentrate on the more restricted commodity and country markets.

description: Driven chaotic systems are of interest in mesoscopic physics, as well as in nuclear, atomic and molecular physics. Such systems [coordinates $(Q,P)$]$ tend to absorb energy. This irreversible effect is known as dissipation. "Driving" means that a parameter $x$ is changed in time. More generally, $x$ may be a dynamical variable. In such case the interaction of $(x,p)$ with the environmental degrees of freedom $(Q,P)$ leads to dephasing as well as to dissipation. We introduce a general framework for the analysis of dissipation and dephasing, and we clarify the tight connection to recent studies of quantum irreversibility (also referred to as "Loschmidt echo" or as the "fidelity" of quantum computation). Specific model systems that will be presented are: particle in a box driven by moving a wall, and particle in a box/ring driven by electro-motive-force. These two examples are related to studies of nuclear friction and mesoscopic conductance.

description: Twenty-five second-year students following the Certificate of Education course in a constituent college of the Liverpool University School of Education were tested with personality and creativity measures. The predictive capacity of the personal data was analysed in terms of the several categories of an interaction analysis schedule applied during observations of the students' teaching. The analysis revealed a quantitatively consistent style of interaction when students were seen on different occasions although inportant changes of a qualitative nature may have occurred. Measures of Ideational Fluency, Flexibility and Originality correlated with the criteria in the same directions and to similar extents, suggesting substantial communality of variance; and there was a tendency for these variables to relate to higher incidences of teacher initiation. Other correlates included Affectothymia (warm, outgoing temperament), artlessness and higher superego strength with the teachers' giving praise; and there were indications that anxiety was linked with teachers' questioning behaviour. Intelligence, as measured by a sub-scale of the personality questionnaire, was not a significant correlate of any behavioural category. The concepts 'personality' and 'creativity', together with their measures, are discussed and related to previous research into teacher competence and behaviour

description: Cold brown dwarfs are excellent analogs of widely separated, gas giant exoplanets, and provide insight into the potential atmospheric chemistry and physics we may encounter in objects discovered by future direct imaging surveys. We present a low resolution R $\sim$ 300 $M$-band spectroscopic sequence of seven brown dwarfs with effective temperatures between 750 K and 250 K along with Jupiter. These spectra reveal disequilibrium abundances of carbon monoxide (CO) produced by atmospheric quenching. We use the eddy diffusion coefficient (K$_{zz}$) to estimate the strength of vertical mixing in each object. The K$_{zz}$ values of cooler gaseous objects are close to their theoretical maximum and warmer objects show weaker mixing, likely due to less efficient convective mixing in primarily radiative layers. The CO-derived K$_{zz}$ values imply that disequilibrium phosphine (PH$_{3}$) should be easily observable in all of the brown dwarfs, but none as yet show any evidence for PH$_{3}$ absorption. We find that ammonia is relatively insensitive to atmospheric quenching at these effective temperatures. We are able to improve the fit to WISE 0855's $M$-band spectrum by including both CO and water clouds in the atmospheric model.

Do weak magnetic fields prevent hydrogen from accreting onto metal-line white dwarf stars?

description: The widely accepted assumption is that metals detected in the spectra of a few cool helium-rich white dwarfs cannot be of primordial origin and therefore must be accreted from the interstellar medium. However, the observed abundances of hydrogen are much too low to be compatible with the high accretion rates inferred from metal accretion. Hydrogen accretion is therefore suppressed compared to metal accretion. The hypothesis most widely discussed as cause for this ``hydrogen screening'' is the propeller mechanism: Metals are accreted in the form of grains onto a slowly rotating, weakly magnetized white dwarf, whereas ionized hydrogen is repelled at the Alfvén radius. We have obtained circular polarization spectra of the helium-rich white dwarfs GD 40 (WD0300-013) and L745-46A (WD0738-172) -- which both show strong metal lines as well as hydrogen -- in order to search for signatures of a weak magnetic field. The magnetic field strengths necessary for the propeller mechanism to work in these stars are at least 144000 G and 3000 G, respectively. Whereas L745-46A might have a magnetic field of about $-$6900 G no magnetic field could be found with an upper limit for the field strength of 4000 G (with 99% confidence) for GD 40.

description: In recent years efforts to develop good research practices have accelerated, and issues of Reproducibility and Replicability (R & R) in computer science experiments have gained attention. Due to the complexity of the approaches used, the reproducibility of deep learning (DL) experiments is a particular challenge. Without the use of DL technology, however, it would be impossible to solve problems which require the acquisition and analysis of enormous amounts of data across space and time. Future users could greatly benefit from the experience of creating and running such experiments, and the challenges to reproducibility of DL experiments should be overcome. To investigate the nature of DL reproducibility challenges in detail and to find solutions that might improve their reproducibility, we assessed three DL studies which analysed visual elements from satellite and street imagery to estimate poverty levels in human settlements. We systematically detailed difficulties with the datasets, methods, and workflows for each experiment and identified actions to militate common problems. Our target audience includes researchers who want to replicate an experiment, authors who want to report on an experiment, and reviewers who want to evaluate DL experiments. As a result of this assessment, we have developed two approaches to improve the reproducibility and replicability of DL experiments: (i) a quality checklist incorporating the relevant FAIR principles inter alia, and (ii) guidelines to reduce the likelihood of wasted effort when deciding whether an experiment is able to be reproduced in a feasible manner.

description: Let $K:=\mathbb{Q}(G)$ be the number field generated by the complex character values of a finite group $G$. Let $\mathbb{Z}_K$ be the ring of integers of $K$. In this paper we investigate the suborder $\mathbb{Z}[G]$ of $\mathbb{Z}_K$ generated by the character values of $G$. We prove that every prime divisor of the order of the finite abelian group $\mathbb{Z}_K/\mathbb{Z}[G]$ divides $|G|$. Moreover, if $G$ is nilpotent, we show that the exponent of $\mathbb{Z}_K/\mathbb{Z}[G]$ is a proper divisor of $|G|$ unless $G=1$. We conjecture that this holds for arbitrary finite groups $G$.

title: Palaeomagnetic studies in the British Caledonides
Creators: name: Morris, William Adrian
Publisher: name: The Open University
Year: 1974

description: In this study a large amount of new palaeomagnetic data is reported from the Paleozoic of the British Isles. The data are consistent with episodic polar shift from the vicinity of 10°N, 180°E in the Ordovician to 0°, 145°E in the Siluro-Devonian and to 25°N, 160°E in the late Devonian-early Carboniferous. The Cambrian pole is less well defined but may have lain near 30°N, 170°E. Each polar shift appears to predate a phase of deformation, i.e. crustal drift and oceanic plate consumption significantly precedes orogenesis and continental plate collision. Large collections were made from two regions within the British Caledonides; the English Lake District, and the South Mayo Trough. Palaeomagnetic data from the Carrock Fell Gabbro Complex indicate intrusion as a dyke at some time during the Upper Ordovician subject only to slight subsequent tilting. Folding in both the Eycott and Borrowdale Volcanic Groups is found to be essentially simple and complete by the end of the Ordovician. The end-Silurian deformation which many authors have considered 'climactic' produced tight folds only in the high-level Silurian sediments. The stratigraphically lower and more competent lavas were merely tilted and cleaved. A similar sequence of deformation has affected the rocks of the South Mayo Trough. In this case however, the end-Silurian deformation accompanied major azimuthal rotation and complicated southward thrusting. A Proto-Atlantic ocean on the site of the present Caledonian orogenic belt has been cited by many authors on a number of separate geological criteria. Palaeomagnetic evidence from the margins of this belt in the British Isles indicates that little (or no) closure has taken place across the Caledonides since early Ordovician time. The available data do however, indicate apparent discrepancies between the Baltic/Russian and North American plates, and a British sub-plate. A number of explanations is possible: (1) Euramerica was a rigid plate, hence some of the data are invalid, (2) the three units of Euramerica were tenuously attached: geological evidence for postulated plate margins outside Britain is discussed (3) the present data are inadequate to define a British sub-plate. In this thesis the third alternative is preferred.

description: We give a simple and direct construction of a massless quantum field with arbitrary discrete helicity that satisfies Wightman axioms and the corresponding relativistic wave equation in the distributional sense. We underline the mathematical differences to massive models. The construction is based on the notion of massless free net (cf. Section 3) and the detailed analysis of covariant and massless canonical (Wigner) representations of the Poincare' group. A characteristic feature of massless models with nontrivial helicity is the fact that the fibre degrees of freedom of the covariant and canonical representations do not coincide. We use massless relativistic wave equations as constraint equations reducing the fibre degrees of freedom of the covariant representation. They are characterized by invariant (and in contrast with the massive case non reducing) one-dimensional projections. The definition of one-particle Hilbert space structure that specifies the quantum field uses distinguished elements of the intertwiner space between E(2) (the two-fold cover of the 2-dimensional Euclidean group) and its conjugate. We conclude with a brief comparison between the free nets constructed in Section 3 and a recent alternative construction that uses the notion of modular localization.

description: Abstract Due to low awareness and low investment in data collection and processing in developing countries, industry has struggled to plan and collaborate with public policy on data-driven socioeconomic decisions. This paper presents a deep learning approach to estimate socioeconomic indicators using satellite imagery. For this purpose, a region in southeastern Brazil called Vale do Ribeira was selected as a study case due to its data availability and environmental relevance. We used publicly available data to analyze three socioeconomic indicators: Longevity, Income and Literacy, the main representatives of the Human Development Index. Our preliminary results show a relevant correlation between satellite imagery and the income indicator, although they are not yet conclusive for longevity and literacy

description: We present a detailed morphological, photometric, and kinematic analysis of two barred S0 galaxies with large, luminous inner disks inside their bars. We show that these structures, in addition to being geometrically disk-like, have exponential profiles (scale lengths $\sim$ 300--500 pc) distinct from the central, non-exponential bulges. We also find them to be kinematically disk-like. The inner disk in NGC 2787 has a luminosity roughly twice that of the bulge; but in NGC 3945, the inner disk is almost ten times more luminous than the bulge, which itself is extremely small (half-light radius $\approx$ 100 pc, in a galaxy with an outer ring of radius $\approx$ 14 kpc) and only $\sim$ 5% of the total luminosity -- a bulge/total ratio much more typical of an Sc galaxy. We estimate that at least 20% of (barred) S0 galaxies may have similar structures, which means that their bulge/disk ratios may be significantly overestimated. These inner disks dominate the central light of their galaxies; they are at least an order of magnitude larger than typical ``nuclear disks'' found in ellipticals and early-type spirals. Consequently, they must affect the dynamics of the bars in which they reside.

A aplicaçãao das novas tecnologias da informação no ensino superior, nomeadamente numa biblioteca universitária, a par da optimização do sistema de difusão dessa mesma informação, foi o que pretendemos estudar; era, alias, nossa intenção, conhecidos já alguns aspectos da experiência inglesa, tomar contacto com a realidade francesa. A Biblioteca da Faculdade de Letras da Universidade de Toulouse - Le Mirail foi, pois, a escolhida, uma vez que reunia condições de preferência excepcionais, entre elas a de possuir um fundo documental temáticamente idêntico o da Biblioteca da Faculdade de Letras da Universidade do Porto, a de não ter ainda uma experiência longa de inforrnatização, a de estar integrada numa estrutura análoga à da U .P. e a de pertencer a uma universidade importante, afastada dos grandes centros de decisão de Paris. Sendo assim, tentaremos, na medida do possível, através deste relatório, dar conta do que nos foi permitido observar, salientando, desde já, o excepcional acolhimento que nos foi prestado e as inumeras facilidades que nos foram concedidas na Biblioteca da F.L.U.T.M.
