Logistics integration processes in the food industry

This paper analyses the integration process that firms follow toimplement Supply Chain Management (SCM). This study has beeninspired in the integration model proposed by Stevens (1989). Hesuggests that companies internally integrate first and then extendintegration to other supply chain members, such as customers andsuppliers.To analyse the integration process a survey was conducted amongSpanish food manufacturers. The results show that there are companiesin three different integration stages. In stage I, companies are notintegrated. In stage II, companies have a medium-high level of internalintegration in the Logistics-Production interface, a low level ofinternal integration in the Logistics-Marketing interface, and a mediumlevel of external integration. And, in stage III, companies have highlevels of integration in both internal interfaces and in some of theirsupply chain relationships.

Endogeneous matching in university-industry collaboration: Theory and empirical evidence from the UK

We develop a two-sided matching model to analyze collaboration between heterogeneousacademics and firms. We predict a positive assortative matching in terms of both scientificability and affinity for type of research, but negative assortative in terms of ability on one sideand affinity in the other. In addition, the most able and most applied academics and the mostable and most basic firms shall collaborate rather than stay independent. Our predictionsreceive strong support from the analysis of the teams of academics and firms that proposeresearch projects to the UK's Engineering and Physical Sciences Research Council.

The yield of high-density electric source imaging in focal epilepsy

Background: EEG is the cornerstone of epilepsy diagnostics and mandatory to determine the underlying epilepsy syndrome (e.g. focal vs idiopathic generalized). However, its potential as imaging tool is still underrecognized. In the present study, we aim to determine the prerequisites of maximal benefit of electric source imaging (ESI) to localize the irritative zone in patients with focal epilepsy. Methods: 150 patients suffering from focal epilepsy and with minimum 1 year post-operative follow-up were studied prospectively by reviewers blinded to the underlying diagnosis and outcome. We evaluated the influence of two important factors on sensitivity and specificity of ESI: the number of electrodes (low resolution, LR-ESI: \30 vs. high resolution, HR-ESI: 128-256 electrodes), and the use of individual MRI (i-MRI) vs. template MRI (t-MRI) as head model.Results: ESI had a sensitivity of 85% and a specificity of 87% when HR-ESI with i-MRI was used. Using LR-ESI, sensitivity decreased to 68%, or even 57% when only t-MRI was available. The sensitivity of HR-ESI/i-MRI compared favorably with those of MRI (76%), PET (69%) and ictal/interictal SPECT (64%).Interpretation: This study on a large patient group shows excellent sensitivity and specificity of ESI if 128 EEG channels or more are used for ESI and if the results are co-registered to the patient's individual MRI. Localization precision is as high as or even higher than established brain imaging techniques, providing excellent costeffectiveness in epilepsy evaluation. HR-ESI appears to be a valuable additional imaging tool, given that larger electrode arrays are easily and rapidly applied with modern EEG equipment and that structural MRI is nearly always available for these patients.

Automatització d'una planta de processos químics

Resum L’any 1969 es van començar a comercialitzar els sistemes digitals programables coneguts com autòmats programables o PLC’s, utilitzats per controlar qualsevol tipus de procés industrial. Al llarg de tots aquests anys, aquests sistemes i tota la tecnologia en general han evolucionat molt, i només és qüestió de temps que la tecnologia que utilitzem avui en dia quedi obsoleta i substituïda per una de millors característiques i amb més avantatges. Aquest és el motiu de l’elaboració d’aquest treball, que com a objectiu pretén modernitzar un procés de fabricació d’una industria química que ha quedat molt limitat a causa de l’antiguitat de la instal•lació. Per dur a terme aquesta modernització, s’introdueixen sistemes de control amb majors prestacions, s’utilitzen xarxes de comunicacions per facilitar el muntatge elèctric de la instal•lació i un sistema de supervisió i adquisició de dades per poder obtenir un control més estricte del procés de fabricació i de tots els factors que intervenen. El funcionament del procés de fabricació és que a partir d’unes matèries primeres líquides emmagatzemades en dipòsits, es dosifiquin aquestes matèries en l’ordre i la quantitat desitjada dins un o diversos recipients per barrejar-les i aplicar els tractaments que siguin necessaris. Tot aquest procés està controlat per un autòmat programable, i disposa de diferents terminals operadors per poder interactuar amb el sistema. També té implementat un sistema SCADA en diversos ordinadors per aportar una visió general de la planta en temps real, un registre de dades dels paràmetres que es controlen i alhora serveix per enllaçar amb la xarxa d’ordinadors existent. Com annex d’aquest treball, es presenten els esquemes elèctrics i el programa de l’autòmat programable per veure totes les característiques elèctriques dels dispositius i el mètode de funcionament del procés. S’ha aconseguit donar un salt tecnològic i poder gaudir de tots els avantatges que ofereixen les noves tecnologies, que com a resultat s’ha optimitzat i millorat el procés de fabricació. De totes les conclusions, la més destacada és la d’haver dissenyat un sistema de control basat en una estructura descentralitzada molt flexible, que es pot expandir i adaptar fàcilment als possibles canvis.

Wind power is the fastest growing source of energy in the nation. New installations have expanded total U.S. generating capacity by 45 percent and injected over $9 billion in new investments into the economy in 2007. These new wind projects accounted for about 30 percent of the entire new power-producing capacity added nationally in 2007. According to our figures at the American Wind Energy Association, installed wind power capacity in the U.S. is now over 16,800 megawatts, and the future looks bright. With every wind turbine that goes up, America’s dependence on fossil fuels for power generation goes down. Wind energy represents a tremendous opportunity to use a non-polluting, inexhaustible source to meet our electric power needs.

Potential use of a chemical leaching reject from a kaolin industry as agricultural fertilizer

The industrial refining of kaolin involves the removal of iron oxides and hydroxides along with other impurities that cause discoloration of the final product and depreciate its commercial value, particularly undesirable if destined to the paper industry. The chemical leaching in the industrial processing requires treatments with sodium hyposulfite, metallic zinc, or sulfuric and phosphoric acids, in order to reduce, dissolve and remove ferruginous compounds. To mitigate the environmental impact, the acidic effluent from the leaching process must be neutralized, usually with calcium oxide. The resulting solid residue contains phosphorous, zinc, and calcium, among other essential nutrients for plant growth, suggesting its use as a macro and micronutrient source. Samples of such a solid industrial residue were used here to evaluate their potential as soil fertilizer in an incubation greenhouse experiment with two soil samples (clayey and medium-textured). The small pH shift generated by applying the residue to the soil was not a limiting factor for its use in agriculture. The evolution of the concentrations of exchangeable calcium, and phosphorous and zinc extractability by Mehlich-1 extractant during the incubation period confirms the potential use of this industrial residue as agricultural fertilizer.

The so-called "Spanish model" - Tobacco industry strategies and its impact in Europe and Latin America

Background To demonstrate the tobacco industry rationale behind the "Spanish model" on non-smokers' protection in hospitality venues and the impact it had on some European and Latin American countries between 2006 and 2011. Methods Tobacco industry documents research triangulated against news and media reports. Results As an alternative to the successful implementation of 100% smoke-free policies, several European and Latin American countries introduced partial smoking bans based on the so-called "Spanish model", a legal framework widely advocated by parts of the hospitality industry with striking similarities to "accommodation programmes" promoted by the tobacco industry in the late 1990s. These developments started with the implementation of the Spanish tobacco control law (Ley 28/2005) in 2006 and have increased since then. Conclusion The Spanish experience demonstrates that partial smoking bans often resemble tobacco industry strategies and are used to spread a failed approach on international level. Researchers, advocates and policy makers should be aware of this ineffective policy.
