description: Double-inoculation of faba bean (Vicia faba L.) seeds before sowing with rhizobium bacteria and mycorrhizal fungi is a known agronomic practice. It improves symbiotic nitrogen fixation and enhances legume supply with mineral elements and water. Effective symbiosis makes it possible to replace some of the required mineral fertilizer needed for plant growth with symbiotically fixed. This will ensure more environmentally friendly agricultural production. The formation of an effective symbiosis depends on a number of biotic and abiotic factors affecting the biochemical signals released by the partners. The biochemical mediator for symbiosis formation is flavonoids. The aim of this experiment was to test the effects of rhizobial and mycorrhizal inocula on symbiosis formation under different temperatures. Beans are an important source of protein for animal feed and human consumption. Four cultivars of faba beans were used - two V. faba var. minor Beck. -‘Fuego’ and ‘Lielplatone’, and two V. faba var. major Harz. - ‘Bartek’ and ‘Karmazyn’. The combination of microorganisms for seed inoculation influenced the frequency of root mycorrhization and abundance of arbuscules. The content of flavonoids in seed exudates correlated (r = 0.93) with germination temperatures. The use of mycorrhizal fungi alone or in combination with rhizobia reduced the amount of flavonoids in the bean seed exudate. In the pot experiment the amount and size of nodules significantly differed between cultivars. Use of mycorrhizal preparation mitigated the effect of inadequate germination temperature. Higher degree of mycorrhization and more intense formation of arbusculs formation was observed in the bean roots grown in vegetation pots in comparison with field ones. Local bred ‘Lielplatone’ had significantly better compatibility with microsymbionts in local agroclimatic conditions.

Palearctic.  Comments
 Dessart & Masner (1965) described Ecnomothorax grangeri from two male and two female specimens, all of which are deposited at the MNHN. The genus Ecnomothorax Dessart & Masner, 1965 was later synonymized with Conostigmus by Dessart & Cancemi (1987).
The female holotype is glued to cardstock (MNHN EY25339), with one slide preparation (prép. no.6501/104) of the right antenna in poor condition (MNHN EY22448). The male allotype is contained within a vial that is point mounted through the cork (MNHN EY25340). There are four associated slides (prép. no. 6501/103), including the left antenna (MNHN EY22446), the right anterior leg (MNHN EY22445), and the last few segments of the metasoma, the pedicel and F1–5 of the right antenna (MNHN EY22444). The fourth slide, containing the male genitalia (MNHN EY22447), is in such poor condition that it is not possible to actually view the genitalia. It is worth mentioning that the microscope preparation numbers given by Dessart & Cancemi (1987) do not match the actual preparation numbers given on the specimen.
There is also a female (MNHN EY 25341) and male (MNHN EY 25342) paratype, both of which are glued to cardstock. Whole-body images were taken of the male paratype in place of the allotype. The female paratype was not imaged.

description: We present a new approach to the covariant canonical formulation of Einstein-Cartan gravity that preserves the full Lorentz group as the local gauge group. The method exploits lessons learned from gravity in 2+1 dimensions regarding the relation between gravity and a general gauge theory. The dynamical variables are simply the frame field and the spin-connection pulled-back to the hypersurface, thereby eliminating the need for simplicity constraints on the momenta. A consequence of this is a degenerate (pre)symplectic form, which appears to be a necessary feature of the Einstein-Cartan formulation. A new feature unique to this approach arises when the constraint algebra is computed: the algebra is a deformation of the de Sitter, anti-de Sitter, or Poincaré algebra (depending on the value of the cosmological constant) with the deformation parameter being the conformal Weyl tensor.

description: Structures, stability, and chemical reactivity of Aun (n = 2-10) clusters are investigated using density functional theory (DFT). We have studied the reactivity parameters of the clusters in terms of relevant electronic structure principles. It is observed that stability and properties are strongly dependent on the cluster size. Clusters with an even number of atoms are found to be energetically and chemically more stable than odd-numbered clusters. Electronic structure of clusters has been investigated using partial density of states (PDOS). PDOS analysis clearly shows that energy states of highest occupied molecular orbital and lowest unoccupied molecular orbital are predominantly contributed by s orbital. From time-dependent DFT calculations, it is shown that absorption spectra of even-numbered clusters are more intense and are observed at lower wavelength region than the odd-sized gold clusters.
title: Dronological Power: Remote Control Occupation and the New Epistemo-Technologies of Sovereignty
Creators: name: Bloomberg, Ramon
Publisher: name: Goldsmiths, University of London
Year: 2022

description: This doctoral thesis takes up the contemporary military drone and seeks to uncover the historical, political, and technical formations veiled by its colloquial apprehension as a remotely controlled unmanned aerial vehicle (UAV). The project has been undertaken as practice-based research in fine art and as such is composed of two equally weighted elements that are mutually constitutive. The practical element takes the form of a literary novel. 

Contextualised within a global military-commercial (mil-com) projection of power, the drone is understood as a producer of knowledge (dronology) and near- sovereign within conditions of generally distributed sovereignty. The drone exerts an algorithmic governmentality differentiated from political governmentality. Agency within the drone ensemble is mutable and intensive across a distributed network topology. If the sovereign state has been in a relationship of recurrent causality with the indivisible sovereign subject, by contrast, the drone is the relation of a sovereign to dividuated forms of life. I argue that the drone is a near- sovereignty that problematises biopolitical theories of power. The mode of power in which the body presupposes the force of law is insufficient for the drone, which I argue is instead a form of sovereign power for which the subject body is no longer meaningful. For the drone, the body lingers on as the hypo-ject – a corollary to the signature. 

The drone is operational across multiple scales. The method of investigation therefore addresses the drone at a plurality of magnitudes. Furthermore, the thesis is framed by two structuring devices: the etymology of the term drone and the case of a 2015 signature strike in the Federally Administered Tribal Area (FATA) of Pakistan. The etymological account demonstrates a historical migration of ways in which the individual has been configured in relation to reason and a political framework. The 2015 signature strike serves to distinguish the current drone from its etymological precedent.

description: Dairy farming in a mixed farming system is a necessary supplementary activity to ensure a constant cash flow. Wheat and dairy1 farming were practised mostly independently, hut over the past 5 years economic conditions in agriculture have changed drastically (tovemment policies focussed on international trade and le ft the agricultural sector in a market where farmers were not competitive and ill prepared for the task. Economic pressure increased and several producers in the Western ('ape region left the industry Wheat farms in some areas in the Swart land without the support of a dairy providing a constant cash flow farmed at a loss. Nevertheless milk and wheat production have increased while many farmers are struggling financially for survival, and its was necessary to take corrective action or leave the industry’. A possible explanation for the increase in production per unit could he attributed to the introduction of advanced technology and improved professional management It is. however, an agricultural characteristic to recover profit by increasing production when profit margin above cost declines In this paper more effective planning in feed cost is investigated as a measure to increase the profit margin above specified costs. Ixibour. veterinary and maintenance, costs are the smaller categories o f the total costs involved although not less important. Research was done on the economy of six typical non-grazing or feedlot dairies in the Swart land by doing income-cost analyses. Viabilities were analysed to reduce production cost by producing all or some of the ingredients in the least-cost feedstuff mixes versus total purchasing of the feedstuffs ('oncentrated feedstuffs are presently purchased from elsewhere and transported over long distances thereby increasing the total cost.
According to Wilie (1995) the main concern of farmers is financial survival and not being able to afford practices which might improve sustainability Their general perception is that sustainability costs money. Too often sustainable farming is discussed with farmers without any reference to profitability

Chloride ion and water balance in the prosobranch gastropod Collisella persona
Creators: name: Clark, Geoffrey A.
Publisher: name: University of British Columbia
Year: 2010

description: The chloride ion concentration of blood, urine, and foot muscle, blood and muscle water content, and blood and urine osmotic pressure, were measured in summer and winter adapted populations of the prosobranch limpet Collisella persona, over a range of salinities from 25% to 125% SW (100% SW = 480 mEq Cl⁻/L). Blood, urine, and foot muscle Cl⁻ were not regulated in all salinities tested. Blood Cl⁻ was generally hypoionic and urine isoionic to the experimental sea water concentrations. Muscle Cl⁻ did not reach a level greater than one-half of equivalent blood or sea water values in all salinities tested. However, muscle and blood values were similar, if muscle Cl⁻ were expressed in terms of extracellular water. Extracellular volume remained relatively unchanged and showed only a 7% increase in salinities ranging from 50% to 125% SW. Seasonal differences were apparent in muscle Cl⁻, with winter values higher than summer values by 20-25 mEq/kg tissue, in salinities ranging from 75% to 125% SW. However, this could be accounted for by the slightly larger (4-8%) extracellular space recorded from winter animals. Summer and winter adapted limpets were osmoconformers in salinities ranging from 25% to 125% SW. Summer animals had blood hyperosmotic, and urine isosmotic to the experimental sea water concentrations. Winter limpets had blood hyperosmotic to 75% SW, and isosmotic in 25% and 125% SW. Urine was hyposmotic to 25% and 75% SW, and isosmotic in 125% SW. Summer blood was hyperosmotic to winter blood, although summer and winter urine remained isosmotic. In addition, for both summer and winter animals, blood was hyperosmotic to urine. The foot muscle water content of winter adapted limpets returned to the control value in 50% to 125% SW, between 48 hours and 1 week. Over the same time period, summer animals only regulated muscle water in 50% and 75% SW. Blood water content remained relatively unchanged for both summer and winter adapted limpets, and showed a 4% decrease over a salinity range from 25% to 125% SW. There were no significant seasonal differences in blood water content. Seasonal differences recorded during the present study, in particular the comparatively large variation in measurements from summer animals, were attributed to seasonal changes in salt and water permeability, or metabolic rate. In addition, an attempt was made to relate the physiological responses recorded from limpets in the laboratory, to the survival of limpets in the field.

description: Prognostics is a process of assessing the extent of deviation or degradation of a product from its expected normal operating condition, and then, based on continuous monitoring, predicting the future reliability of the product. By being able to determine when a product will fail, procedures can be developed to provide advanced warning of failures, optimize maintenance, reduce life cycle costs, and improve the design, qualification and logistical support of fielded and future systems. In the case of electronics, the reliability is often influenced by thermal loads, in the form of steady-state temperatures, power cycles, temperature gradients, ramp rates, and dwell times. If one can continuously monitor the thermal loads, in-situ, this data can be used in conjunction with precursor reasoning algorithms and stress-and-damage models to enable prognostics. This paper discusses approaches to enable electronic prognostics and provides a case study of prognostics using thermal data.

This long-baseline experiment measures neutrino interactions in Fermilab's NuMI neutrino beam with a near detector at Fermilab and again 735 km downstream with a far detector in the Soudan Underground Laboratory in northern Minnesota. The two detectors are magnetized steel-scintillator tracking calorimeters. They are designed to be as similar as possible in order to ensure that differences in detector response have minimal impact on the comparisons of event rates, energy spectra and topologies that are essential to MINOS measurements of oscillation parameters. The design, construction, calibration and performance of the far and near detectors are described in this paper.

description: The cosmic large-scale structures of the Universe are mainly the result of the gravitational instability of initially small density fluctuations in the dark-matter distribution. Dark matter appears to be initially cold and behaves as a continuous and collisionless medium on cosmological scales, with evolution governed by the gravitational Vlasov--Poisson equations. Cold dark matter can accumulate very efficiently at focused locations, leading to a highly non-linear filamentary network with extreme matter densities. Traditionally, investigating the non-linear Vlasov--Poisson equations was typically reserved for massively parallelised numerical simulations. Recently, theoretical progress has allowed us to analyse the mathematical structure of the first infinite densities in the dark-matter distribution by elementary means. We review related advances, as well as provide intriguing connections to classical plasma problems, such as the beam-plasma instability.

description: A trimer is an object composed of three centimetrical stainless steel beads equally distant and is predestined to show richer behaviours than the bouncing ball or the bouncing dimer. The rigid trimer has been placed on a plate of a electromagnetic shaker and has been vertically vibrated according to a sinusoidal signal. The horizontal translational and rotational motions of the trimer have been recorded for a range of frequencies between 25 and 100 Hz while the amplitude of the forcing vibration was tuned for obtaining maximal acceleration of the plate up to 10 times the gravity. Several modes have been detected like e.g. rotational and pure translational motions. These modes are found at determined accelerations of the plate and do not depend on the frequency. By recording the time delays between two successive contacts when the frequency and the amplitude are fixed, a mapping of the bouncing regime has been constructed and compared to that of the dimer and the bouncing ball. Period-2 and period-3 orbits have been experimentally observed. In these modes, according to observations, the contact between the trimer and the plate is persistent between two successive jumps. This persistence erases the memory of the jump preceding the contact. A model is proposed and allows to explain the values of the particular accelerations for which period-2 and period-3 modes are observed. Finally, numerical simulations allow to reproduce the experimental results. That allows to conclude that the friction between the beads and the plate is the major dissipative process.

 Kieffer (1907a) described the female of the species, but it is unknown how many specimens Kieffer observed or where the specimen(s) are. There is a double point-mounted female specimen at the MNHN (MNHN EY25346) with locality information matching that given in Kieffer (1907a). Dessart left a label on this specimen in 1973 designating it the female paralectotype of Conostigmus leviventris, while also leaving the comment “= rufescens f. ailee!”. However, Dessart never formally synonymized C. leviventris with C. rufescens. The identity and whereabouts of the implied lectotype are unknown. The female specimen is double point mounted and in poor condition. Unfortunately, the specimen is missing its head, and the pin it is double point-mounted on has begun to rust.

description: We present a numerical method for the evaluation of the mass gap, and the low-lying energy gaps, of a large family of free-fermionic and free-parafermionic quantum chains. The method is suitable for some generalizations of the quantum Ising and XY models with multispin interactions. We illustrate the method by considering the Ising quantum chains with uniform and random coupling constants. The mass gaps of these quantum chains are obtained from the largest root of a characteristic polynomial. We also show that the Laguerre bound, for the largest root of a polynomial, used as an initial guess for the largest root in the method, gives us estimates for the mass gaps sharing the same leading finite-size behavior as the exact results. This opens an interesting possibility of obtaining precise critical properties very efficiently which we explore by studying the critical point and the paramagnetic Griffiths phase of the quantum Ising chain with random couplings. In this last phase, we obtain the effective dynamical critical exponent as a function of the distance-to-criticality. Finally, we compare the mass gap estimates derived from the Laguerre bound and the strong-disorder renormalization-group method. Both estimates require comparable computational efforts, with the former having the advantage of being more accurate and also being applicable away from infinite-randomness fixed points. We believe this method is a relevant tool for tackling critical quantum chains with and without quenched disorder.

description: Three symmetrical and unsymmetrical nickel(II) complexes [cis-(C3H7)2NC(S)NC(O)C6H3(3,5-NO2)2]2Ni(II), [cis-(C4H9)2NC(S)NC(O)C6H3(3,5-NO2)2]2Ni(II), and [cis-(Hex)(Me)2NC(S)NC(O) C6H3(3,5-NO2)2]2Ni(II) were synthesized and characterized by FTIR spectroscopy, elemental analysis, and mass spectrometry. These metal complexes have been used as single-source precursors for the preparation of semiconducting nickel sulfide nanocrystals. Rapid injection of metal complexes into oleylamine at 230°C, followed by immediate cooling, led to the formation of irregular-shaped 20–170-nm nickel sulfide nanocrystals. The deposited nickel sulfide nanocrystals were characterized by X-ray powder diffraction and transmission electron microscopy.
Extension Services in Sub-Saharan Africa: Recent Developments in Nigeria and Implications for the Future

description: Some thirty-one countries in Sub-Saharan Africa, including Nigeria, adopted the d raining and Visits (T&V) system of extension services sponsored by the World Bank. The aim of the programme was to provide comprehensive agricultural extension (Crop, livestock, forestry and fishery) within a single line of command. The World Bank loan facilities provided, at times, as high as 65 percent of the total fund requirement while the host country contributed the balance. Available information shows that following the withdrawal of the World Bank financial commitment in some of the countries extension activities of these projects have stagnated and halted. The funding for the project is grossly inadequate now and there is no prospect for improvement in the future, considering the limited resources, other competing demands, and the sophistication in extension services. For a sustainable extension service, the paper is proposing a comprehensive review of the activities and functions of the agricultural development projects which supervise extension service delivery. Instead of the general and assembly-line model of technology diffusion in which blanket solutions were given to localised problems, customised packages and environmentally friendly solutions based on farmers involvement should be adopted. The possibility of private sector cofinancing of extension services should be fully explored to alleviate financial problems and complement public funds.

description: When we see a potential collision about to happen, we will do just about anything to avoid it, and sometimes, through skill, quick thinking or blind luck, we do. We’ve all experienced those near misses – the close calls. Maybe we’re a pedestrian in a crosswalk who skips out of the way of a vehicle, or the driver who swerves to miss that car making a Pittsburgh left. These stories are often told throughout the day, but they are rarely reported. However, these stories can have much deeper value if the underlying cause could be understood and remedied, so that future collisions can be avoided and lives can be saved.

CMU researchers are deploying a “City Scale Computing” AI-enabled pilot project in a real-world laboratory on the busy streets of Pittsburgh to help tell this story and reduce (and potentially eliminate) near misses. This project, supported in part by CMU’s Metro21: Smart Cities Institute, is capturing and processing high resolution video to facilitate computer vision algorithms research. In coordination with their partners, researchers are also using the test bed to address privacy, power management, data-management, and policy challenges associated with dense, high-resolution urban video capture. Their research will inform and enable future connected vehicle to infrastructure (V2X) deployments and address issues such as blind spots and other safety-related challenges.

This session, presented in a moderated session format, brought together a dynamic panel of CMU faculty, along with their municipal and industry partners to explore how scientific data can empower people and affect policy. Panelists will discuss how public-private partnerships can help solve real world problems, as well as inform the future states of artificial intelligence and connected vehicles.

description: Thermal measurement and modeling of multi-die packages became a hot topic recently in different fields like RAM chip packaging or LEDs / LED assemblies, resulting in vertical (stacked) and lateral arrangement. In our present study we show results for a mixed arrangement: an opto-coupler device has been investigated with 4 chips in lateral as well as vertical arrangement. In this paper we give an overview of measurement and modeling techniques and results for stacked and MCM structures, describe our present measurement results together with our structure function based methodology of validating the detailed model of the package being studied. Also, we show how to derive junction-to-pin thermal resistances with a technique using structure functions.

description: A framework is outlined to assess Cepheids as potential cluster members from readily available photometric observations. A relationship is derived to estimate colour excess and distance for individual Cepheids through a calibration involving recently published HST parallaxes and a cleaned sample of established cluster Cepheids. Photometric (V-J) colour is found to be a viable parameter for approximating a Cepheid's reddening. The non-universal nature of the slope of the Cepheid PL relation for BV photometry is confirmed. By comparison, the slopes of the VJ and VI relations seem relatively unaffected by metallicity. A new Galactic Cepheid confirmed here, GSC 03729-01127 (F6-G1 Ib), is sufficiently coincident with the coronal regions of Tombaugh 5 to warrant follow-up radial velocity measures to assess membership. CCD photometry and O--C diagrams are presented for GSC 03729-01127 and the suspected cluster Cepheids AB Cam and BD Cas. Fourier analysis of the photometry for BD Cas and recent estimates of its metallicity constrain it to be a Population I overtone pulsator rather than a Type II s-Cepheid. AB Cam and BD Cas are not physically associated with the spatially-adjacent open clusters Tombaugh 5 and King 13, respectively, the latter being much older (log t ~ 9) than believed previously. Rates of period change are determined for the three Cepheids from archival and published data. GSC 03729-01127 and AB Cam exhibit period increases, implying fifth and third crossings of the instability strip, respectively, while BD Cas exhibits a period decrease, indicating a second crossing, with possible superposed trends unrelated to binarity. More importantly, the observed rates of period change confirm theoretical predictions. The challenges and prospects for future work in this area of research are discussed.

Comments
Specimens from Guangxi Province of mainland China (Fig. 39D–F) have propodeal spines that are slightly broader and less developed than those of the specimens from Taiwan (Fig. 39G–I), and not armed at a distinct upward angle; the specimens from Guangxi (TL 2.0, ML 0.49–0.50) are also slightly smaller than those from Taiwan (TL 2.2–2.3, ML 0.55–0.60). No other major morphological difference is observed; hence, we consider specimens from Guangxi as S. takasago. This is the first record of the species within continental Asia, indicating it is not endemic to Taiwan.

description: An efficient condition for the microwave synthesis of nitroalkanes from α,β-unsaturated nitroalkenes using tri-n-butyltin hydride as a mild reducing reagent under aqueous conditions is described. A variety of conjugated nitroalkenes have undergone reduction chemoselectively to yield corresponding nitroalkanes up to 95% yield in 8–30 min. Also, a possible ionic mechanism involving a six-membered cyclic transition state has been proposed.
Seesaw lepton masses and muon $g-2$ from heavy vector-like leptons

description: We propose a model for the vector-like lepton to explain the small muon mass by a seesaw mechanism, based on lepton-specific two Higgs doublet models with a local $U(1)'$ symmetry. There is no bare muon mass for a nonzero $U(1)'$ charge of the leptophilic Higgs doublet, so the physical muon mass is generated due to the mixing between the vector-like lepton and the muon after the leptophilic Higgs doublet and the dark Higgs get VEVs. In this scenario, the non-decoupling effects of the vector-like lepton give rise to leading contributions to the muon $g-2$, thanks to the light $Z'$ and the light dark Higgs boson. We discuss various constraints on the model from lepton flavor violation, electroweak precision and Higgs data, as well as collider searches.

description: Bekenstein's alternative to general relativity, TeVeS, reduces to Modified Newtonian Dynamics (MOND) in the galactic limit. On cosmological scales, the (potential well overdensity) relationship is quite different than in standard general relativity. Here we investigate the possibility of cross-correlating galaxies with the cosmic microwave background (CMB) to probe this relationship. At redshifts of order 2, the sign of the CMB-galaxy correlation differs in TeVeS from that in general relativity. We show that this effect is detectable and hence can serve as a powerful discriminator of these two models of gravity.

The National Salvation Association : the case of the seven worthies
Creators: name: Francis, Lesley Jean
Publisher: name: University of British Columbia
Year: 2010

description: The National Salvation Association brought into prominence and temporary alliance social forces that would figure importantly in the tempestuous course of the following decades: the dissident intellectuals and professionals, the more or less modernized or Westernized elements of the urban population and part of the commercial sector of the population. They shared a sense of the need to save China from external aggression and civil war. Moreover, they desired change in China. The National Salvation Association acted as a vehicle for modernization, and a catalyst for change. From this study it is evident that the National Salvation Association was well organized with effective group leadership. During the fifteen months after its formal inauguration (May 1936), the National Salvation Association, in the face of ever-increasing KMT efforts to control the press, produced a large quantity of literature. Some of this literature, as well as a wide selection of biographical, reminiscent and commemorative materials, has greatly aided the present study. This has been supplemented by various periodicals and newspapers of the period. As a microcosm of the National Salvation Association as a whole, an examination of the Shanghai Women's National Salvation Association has shown first, that not only was the participation of women in the Shanghai Women's National Salvation Association a continuation of a politicization trend but that these women were at least as militant and politically sensitive as their male counterparts. Second, the Shanghai Women's National Salvation Association was characterized by a curious amalgamation of Shanghai's female labour force and women intellectuals and professionals. Both the leadership and the support base of the National Salvation Association were marked by a preponderance of intellectuals and professionals. They used the printed medium to espouse wider liberal-democratic socio-political concerns. The case of the seven worthies brought the seven Shanghai National Salvation leaders to national prominence; they became in effect a cause celebre for democratic rights. But, the enduring significance of the National Salvation Association was that the prominence afforded by the trial made possible the use of these people as symbols for the united front. Five of the seven retained prominent positions during the Sino-Japanese War through involvement with the Democratic League.
Regional Economic Integration and West Africa's Agricultural Export Trade: Challenges and Options
Creators: name: Odey, L.I.
Publisher: name: Unknown
Year: 1999
Subjects: International Relations/Trade

description: Since the establishment of the EEC in the late 1950s, the wave of Economic Integration has been intense. Alongside has been the emerging globalisation given impetus to by the Bretton Woods institutions and the World Trade Organisation (WTO). As integration entails some measure of protectionism, it limits market access and share in world trade with grave implications for the agricultural export trade of H 'est African sub- region. Thus, debate has ensued on how to reconcile the existence of various regional trading blocks with globalisation. This paper has two major objectives; (a) examining the compatibility of the concept of economic integration with the trade liberalisation goal of the WTO and (b) highlighting any challenge(s) this may pose to the outward commodity trade of the sub-region. The study shows that the use of common external tariffs and other concessions extended to members within a trading block are restrictive and, therefore, negate the principle of free trade. Within the regional context, however, economic integration plays a major role in promoting trade and capital flows across borders. Thus, it could be said to be a building block 'to achieving the global objective. The major challenge faced by the economies of W est African states is that of competitiveness both in produce pricing and quality, and even in their investment environment. To achieve this competitiveness, problems such as declining market share, export of raw commodities, weaknesses in marketing and financial sector support, the use of banned agro-chemicals and environmental problems must first be addressed. To this end, the current efforts at deregulation of their economies and return to democratic, open and transparent governance must be sustained. On agricultural sector-specific level, regional processing plants and commodity exchanges should be set up to add value to produce and enhance marketing channel efficiency. Other recommendations given in the paper include; proper use of only acceptable agro-chemicals and a well coordinated plan to tackle the menace of environmental problems.
The challenge is no doubt great but with the enormous agricultural potentials in the sub-region and the right macro-economic environment, commodity trade can be the engine of growth in the economies of West Africa.

description: Besides their electrical properties the optical parameters of LEDs also depend on junction temperature. For this reason thermal characterization and thermal management play important role in case of power LEDs, necessitating both physical measurements and simulation tools. The focus of this paper is a combined electrical, thermal and optical characterization of power LED assemblies. In terms of simulation a method for board-level electro-thermal simulation is presented, for measurements a combined thermal and radiometric characterization system of power LEDs and LED assemblies is discussed. Comparison of measurement and simulation results is presented in a case study.
