Asiakasarvon kehittäminen B2B-palveluyrityksessä

Yritysten välisen yhteistyön toimittajavalinta perustuu asiakasarvon määrittämiseen ja vertailuun. Tämä tutkimus tehtiin yritys A:lle asiakasarvon ymmärtämiseksi, kehittämiseksi ja asiakaspääoman kasvattamiseksi. Teoreettisesti keskeisiä käsiteltäviä teemoja ovat asiakasarvon luonti, toimittaminen ja kasvattaminen. Tutkimus on toteutettu pääasiassa kvalitatiivisesti teemahaastattelun kautta, jossa haastateltiin viittä yritys A:n asiakasyritystä. Tutkimus suunniteltiin yhdessä työn tilanneen yrityksen kanssa suhteessa aiempiin tutkimuksiin ja tavoitteisiin. Tutkimuksen tuloksissa havaittiin selviä vahvuuksia liittyen yritys A:n asiakasyritysten asiakasarvon teemoihin. Vahvuudet liittyivät muun muassa suoriin kustannuksiin, erillisiin lisäpalveluihin ja asiakaspalveluun. Kehitettävät teemat liittyivät pääasiassa työn suorittamiseen ja markkinointiin. Tulokset ovat käsitelty niin numeerisesti kuin tärkeimpinä teemoina. Asiakasarvoon ja –pääomaan liittyvistä teemoista esitetään lopuksi ratkaisuehdotus työn tilanneelle yritykselle, jota voidaan hyödyntää jatkossa ko. johtamisessa. Asiakasarvosta tulisi tehdä niin yrityskohtaisesti kuin tieteen kannalta lisää tutkimusta, sillä siinä on onnistuessaan merkittävä liiketoiminnallinen potentiaali.

Evaluation Of An Extended Duct Air Delivery System For Spaces Conditioned By Rooftop Units

Traditional air delivery to high-bay buildings involves ceiling level supply and return ducts that create an almost-uniform temperature in the space. Problems with this system include potential recirculation of supply air and higher-than-necessary return air temperatures. A new air delivery strategy was investigated that involves changing the height of conventional supply and return ducts to have control over thermal stratification in the space. A full-scale experiment using ten vertical temperature profiles was conducted in a manufacturing facility over one year. The experimental data was utilized to validated CFD and EnergyPlus models. CFD simulation results show that supplying air directly to the occupied zone increases stratification while holding thermal comfort constant during the cooling operation. The building energy simulation identified how return air temperature offset, set point offset, and stratification influence the building’s energy consumption. A utility bill analysis for cooling shows 28.8% HVAC energy savings while the building energy simulation shows 19.3 – 37.4% HVAC energy savings.

Protected cropping for specialty melons in North Queensland

Protective cropping could be an effective system for growing specialty melons in the dry tropics of North Queensland. The growing system could reduce outdoor risks for production loss, improve fruit quality, increase yield per m2, allow production offseason, and used for supplying niche markets in a segment of the larger melon market in Australia. First evaluations in Giru, Queensland, included seven cultivars of fruit types 'Galia', 'Hami', 'Charentais', small 'Canary', and 'Rockmelon', transplanted July 25, 2013 under a high polyethylene-covered tunnel. Plants were grown at a density of 2.8 plants m-2 in containers filled with volcanic rock and irrigated with a complete nutrient solution. Pruning and trellising was done to a single vertical stem, keeping lateral shoots on the main stem after the 7th leaf node. After bearing small fruit, lateral shoots were cut off after their second or third leaf node. To facilitate insect pollination, a screen window in the tunnel was left partially opened. On November 20 the cultivars had combined marketable yields that ranged from 2.8 to 8.2 fruits m-2 and 3.1 to 7.8 kg m-2. Total soluble solids levels in fruit ranged from 6 to 13 °Brix. Cultivars 'Tempo' ('Galia'), 'Tikal' ('Canary') and 'Sultan' ('Charentais') had fruit yields that were up to 2.6 times greater than yields commonly achieved with field-grown rockmelon crops. Sugar levels in fruits and marketable yields may be increased with changes in fertigation management. Promising results in this first evaluation justify examination of a greater number of genetic materials, in addition to the development of economic feasibility studies and further adaptive research to refine crop recommendations for growing melons in protective cropping systems.

Universidade Metodista Unida de Moçambique [UMUM]

Partindo dos princípios que norteiam a UMUM, não esquecendo os pontos de referência da evolução transdisciplinar da educação – partir da/para a realidade – e tendo em mente que a estrutura student oriented sustenta a organização dos cursos, problematizamos a opção pela oferta, no 1º ano da licenciatura, de um conjunto de quatro disciplinas curriculares transversais a todos os cursos. Cientes de que a educação implica a vivência da interculturalidade e a inclusão social, o alvo é identificar o papel que a língua desempenha na descoberta do ‘eu’, na sua aceitação e consolidação, para que seja viável comunicar, agir e (con)viver em sociedade; na vivência pacífica do ‘eu’ com o ‘outro’; na construção colaborativa dos saberes e dos saberes fazeres. Daí decorre que as disciplinas curriculares transversais escolhidas, para induzir e potenciar uma educação de qualidade, tenham sido o Português, enquanto língua oficial, o Inglês, enquanto língua franca, as Tecnologias da Informação e Comunicação, como mediadoras da comunicação, promotoras de redes e de comunidades de aprendizagem para a construção do conhecimento e, ainda, Diálogos, Paz e Desenvolvimento, propiciando uma emergência equilibrada do sujeito per se, na sua relação com o ‘outro’ e com o mundo – saber ser e saber conviver. Questionamos a metodologia a utilizar nestas disciplinas curriculares, respeitando as suas especificidades, sustentando as áreas científicas contempladas em cada curso, numa dinâmica inter/transdisciplinar, implicando os estudantes na realidade e na complexidade do conhecimento e, em complementaridade, desafiando os docentes para o trabalho colaborativo.

Harvesting and Collection of Animal Forest Species

The harvest and trade of corals and other benthic organisms from the world’s shallow tropical reefs is a lucrative industry that can have positive socioeconomic benefits for communities while supplying the increasing demand specimens for aquaria and curios. For most countries, this trade has historically been almost entirely unregulated. More recently, in response to concerns about the rapid decline of some reefs in the face of anthropogenic and natural pressures, as well as indications of depletions and even localized extinctions of some species caused by harvesting, there have been attempts to improve the sustainability of the industry. Both developing and developed countries face different impediments to this reform, the most pressing and common of which is the lack of reliable data on world trade through CITES. Thereafter, differences in the processes through which reform can be implemented are based principally on the length of the supply chain from collection to export, the degree of industry stewardship, and resourcing. The coral collection fishery in Queensland, Australia, provides an example where continual improvements in reporting and risk assessments and adopting a comanagement approach are delivering better adaptive management of the resource, although the on-ground sustainability benefits of this approach are still to be tested. A simpler approach to sustainable use of coral is to favor the replacement of wild harvested specimens with those bred or grown entirely in an aquaculture facility (as opposed to merely collected and then grown out in culture). Yet there are major impediments to this change, including the dependence of many public aquaria on the same sources as the hobbyist community, difficulties of culturing some species in captivity, and infrastructure costs. Nevertheless, this approach will likely play an important part in reef conservation efforts in the future.

Antioxidant potential of two Apiaceae plant extracts: a comparative study focused on the phenolic composition

The present study aimed to characterize the extracts prepared from Pimpinella anisum L. (anise) and Coriandrum sativum L. (coriander) (Apiaceae plants) seeds in terms of phenolic composition, and to correlate the obtained profiles with the antioxidant activity. Anise gave the highest abundance in phenolic compounds (42.09± 0.11 mg/g extract), mainly flavonoids (28.08±0.17 mg/g extract) and phenolic acids (14.01±0.06 mg/g extract), and also the highest antioxidant potential, measured by the ability to inhibit lipid peroxidation and β-carotene bleaching, the reducing power and the free radical scavenging activity. Apigenin and luteolin derivatives, as also caffeoylquinic acid derivatives seem to be directly related with the higher in vitro antioxidant potential of the anise extract. In contrast, the lower antioxidant potential of coriander seems to be due to its lower abundance in phenolic compounds (2.24±0.01 mg/g extract). Further studies are necessary to evaluate the in vivo antioxidant potential of the tested extracts, but the in vitro experiments already performed highlight them as potential health promoters.

Release of available nitrogen from river-discharged dissolved organic matter by heterotrophic bacteria associated with the cyanobacterium Microcystis aeruginosa

The use of riverine dissolved organic matter by the heterotrophic bacteria associated with a culture of the cyanobacterium Microcystis aeruginosa and release of simple nitrogen compounds were studied in an experimental series. Bacteria reduced the bulk of dissolved organic nitrogen (DON) by half, but when associated with M. aeruginosa, DON was excreted and its concentration rose by 13%. During the stationary growth phase bacteria released ammonium, doubling the concentration of ammonia as well as of nitrates. Bacteria associated with M. aeruginosa consumed riverine DON and joined the ammonification and nitrification process, supplying cyanobacteria with simple nitrogen compounds.

La interdependencia hispano-argelina en cuestiones energéticas

Desde los años 1980 España y Europa importan una parte creciente de sus hidrocarburos de Argelia. Esta situación ha llevado a una interdependencia que puede resultar peligrosa por ambas partes. España no consigue reducir su consumo de hidrocarburos, pero en su esfuerzo por diversificar e independizarse del petróleo ha incrementado significativamente el consumo de gas natural procedente de Argelia. Por su parte este país ha aumentado sus reservar en divisas lo que le ha permitido mejorar extraordinariamente su situación desde la guerra civil de los años 1990 y garantizar a corto plazo el estatus quo social y político. Sin embargo esa misma dependencia de los hidrocarburos le impide resolver los graves problemas estructurales de su juventud y de una economía rentista. Esta comunicación estudia estas dependencias analizando la creciente complejidad del mercado de los hidrocarburos, los esfuerzos españoles por diversificar sus fuentes de abastecimiento y las apuestas de Argelia por continuar suministrando energía primaria.

EXPERIMENTAL DEMONSTRATION OF LIGHT TRAPPING AND INTERNAL LIGHT SCATTERING IN SOLAR CELLS

Renewable energy technologies have long-term economic and environmental advantages over fossil fuels, and solar power is the most abundant renewable resource, supplying 120 PW over earth’s surface. In recent years the cost of photovoltaic modules has reached grid parity in many areas of the world, including much of the USA. A combination of economic and environmental factors has encouraged the adoption of solar technology and led to an annual growth rate in photovoltaic capacity of 76% in the US between 2010 and 2014. Despite the enormous growth of the solar energy industry, commercial unit efficiencies are still far below their theoretical limits. A push for thinner cells may reduce device cost and could potentially increase device performance. Fabricating thinner cells reduces bulk recombination, but at the cost of absorbing less light. This tradeoff generally benefits thinner devices due to reduced recombination. The effect continues up to a maximum efficiency where the benefit of reduced recombination is overwhelmed by the suppressed absorption. Light trapping allows the solar cell to circumvent this limitation and realize further performance gains (as well as continue cost reduction) from decreasing the device thickness. This thesis presents several advances in experimental characterization, theoretical modeling, and device applications for light trapping in thin-film solar cells. We begin by introducing light trapping strategies and discuss theoretical limits of light trapping in solar cells. This is followed by an overview of the equipment developed for light trapping characterization. Next we discuss our recent work measuring internal light scattering and a new model of scattering to predict the effects of dielectric nanoparticle back scatterers on thin-film device absorption. The new model is extended and generalized to arbitrary stacks of stratified media containing scattering structures. Finally, we investigate an application of these techniques using polymer dispersed liquid crystals to produce switchable solar windows. We show that these devices have the potential for self-powering.

Simultaneous estimation of the nutritional contribution of fish meal, soy protein isolate and corn gluten to the growth of Pacific white shrimp (Litopenaeus vannamei) using dual stable isotope analysis

The nutritional contribution of the dietary nitrogen, carbon and total dry matter supplied by fish meal (FM), soy protein isolate (SP) and corn gluten (CG) to the growth of Pacific white shrimp Litopenaeus vannamei was assessed by means of isotopic analyses. As SP and CG are ingredients derived from plants having different photosynthetic pathways which imprint specific carbon isotope values to plant tissues, their isotopic values were contrasting. FM is isotopically different to these plant meals with regards to both, carbon and nitrogen. Such natural isotopic differences were used to design experimental diets having contrasting isotopic signatures. Seven isoproteic (36% crude protein), isoenergetic (4.7 kcal g−1) diets were formulated; three diets consisted in isotopic controls manufactured with only one main ingredient supplying dietary nitrogen and carbon: 100% FM (diet 100F), 100% SP (diet 100S) and 100% CG (diet 100G). Four more diets were formulated with varying mixtures of these three ingredients, one included 33% of each ingredient on a dietary nitrogen basis (diet 33FSG) and the other three included a proportion 50:25:25 for each of the three ingredients (diets 50FSG, 50SGF and 50GFS). At the end of the bioassay there were no significant differences in growth rate in shrimps fed on the four mixed diets and diet 100F (k=0.215–0.224). Growth rates were significantly lower (k=0.163–0.201) in shrimps grown on diets containing only plant meals. Carbon and nitrogen stable isotope values (δ13C and δ15N) were measured in experimental diets and shrimp muscle tissue and results were incorporated into a three-source, two-isotope mixing model. The relative contributions of dietary nitrogen, carbon and total dry matter from FM, SP and CG to growth were statistically similar to the proportions established in most of the diets after correcting for the apparent digestibility coefficients of the ingredients. Dietary nitrogen available in diet 33FSG was incorporated in muscle tissue at proportions representing 24, 35 and 41% of the respective ingredients. Diet 50GSF contributed significantly higher amounts of dietary nitrogen from CG than from FM. When the level of dietary nitrogen derived from FM was increased in diet 50FSG, nutrient contributions were more comparable to the available dietary proportions as there was an incorporation of 44, 29 and 27% from FM, SP and CG, respectively. Nutritional contributions from SP were very consistent to the dietary proportions established in the experimental diets.

Drug development:the cell wall as a drug target

The complex and essential cell wall of Mycobacterium tuberculosis represents a plethora of new and old drug targets that collectively form an apparent mycobacterial “Achilles’ heel”. The mycolic acids are long-chain α-alkyl-β-hydroxy fatty acids (C70–90), which are unique to mycobacterial species, forming an integral component of the mycolyl–arabinogalactan–peptidoglycan complex. Their apparent uniqueness to the M. tuberculosis complex has rendered components of mycolic acid biosynthesis as powerful drug targets for specific tuberculosis (TB) chemotherapy. Here, I will discuss a contribution to TB drug discovery by deconvolution of the inhibitory mechanisms of a number of antitubercular compounds targeting mycolic acid biosynthesis. I will begin with the early days, elucidating the mode of action of ethionamide [1] and thiolactomycin [2], each targeting two separate components of the fatty acid synthase II (FAS-II) pathway. I will further discuss the recently discovered tetrahydropyrazo[1,5-a]pyrimidine-3-carboxamide compounds [3] which selectively target the essential, catalytically silent M. tuberculosis EchA6, providing a crucial lipid shunt between β-oxidation and FAS-II and supplying lipid precursors for essential mycolate biosynthesis. Finally, I will discuss the recent discovery of the mode of action of the indazole sulfonamides [4], inhibiting M. tuberculosis KasA by, a completely novel inhibitory mechanism.

Influencia del interés geopolítico de China en sus relaciones bilaterales con Camboya

La presente investigación tiene como objetivo analizar cómo las relaciones bilaterales entre China y Camboya son afectadas por el interés geopolítico chino, con el fin de demostrar que éste genera un fortalecimiento de sus relaciones puesto que además de suplir necesidades alimenticias, hídricas y en mano de obra barata, es el único país de la región del Sudeste Asiático que le permite a China tener acceso militar al Golfo de Tailandia y al Mar de China Meridional, donde se encuentra en desventaja con Estados Unidos. Así, se indica que la potencia asiática formula sus acuerdos bilaterales creando relaciones de dependencia por parte de países como Camboya para que este le entregue “obligatoriamente” lo que necesita. Esta investigación se llevará a cabo por medio de una monografía con un enfoque realista. Se utilizará el método de investigación cualitativo, que se servirá de fuentes primarias como los acuerdos bilaterales entre ambos Estados.
