Use of Biostimulants for Organic Apple Production: Effects on Tree Growth, Yield, and Fruit Quality at Harvest and During Storage
2018
The experiment was conducted during two consecutive seasons (years 2016 and 2017) in an organic apple orchard of the cultivar Jonathan. Several biostimulants were tested (10 in total), including humic acids, macro and micro seaweed extracts, alfalfa protein hydrolysate, amino acids alone or in combination with zinc, B-group vitamins, chitosan and a commercial product containing silicon. Treatments were performed at weekly intervals, starting from the end of May until mid-August. The macroseaweed extract was effective in stimulate tree growth potential in both years, as shown by a significantly larger leaf area (+20% as compared to control) and by an higher chlorophyll content and leaf photo…
Cloud product capability assessment method
2015
Tutkimuksen tavoitteena on lisätä osaamista tuotehallintaan, miten IT-palveluhallinta- ja kokonaisarkkitehtuurimenetelmiä voidaan integroida pilvipalveluiden tuotteistamiseen. Tutkimuksen toisena tavoitteena on rakentaa uusi pilvipalveluiden kyvykkyyksien hallintamenetelmä, jonka avulla pilvipalveluiden tuotteistusta voidaan hallita ideasta markkinoille saamiseen asti. Uusi menetelmä on tarkoitettu tuote- ja projektipäälliköille sekä arkkitehdeille, jotka työskentelevät pilvipalveluiden kanssa. Pilvipalvelulle luodaan liiketoiminnan näkökulmasta uusi määritelmä, annetaan lyhyt esittely pilvipalveluiden tuotehallinnasta sekä määritellään tarve liiketoiminnan ketteryydelle. IT-näkökulmassa tu…
Comparison of Post-Weld Treatment of High-Strength Steel Welded Joints in Medium Cycle Fatigue
2010
This paper presents a comparison of three post-weld treatments for fatigue life improvement of welded joints. The objective is to determine the most suitable post-weld treatment for implementation in mass production of certain crane components manufactured from very high-strength steel. The processes investigated are: burr grinding, TIG dressing and ultrasonic impact treatment. The focus of this investigation is on the so-called medium cycle area, i.e. 10 000-500 000 cycles and very high stress ranges. In this area of fatigue design, the use of very high strength steel becomes necessary, since the stress range can exceed the yield-strength of ordinary structural steel, especially when consi…
Wpływ sposobu dawkowania preparatu enzymatycznego na zmiany mikrobiologiczne i przemiany węglowodorów alifatycznych w glebie skażonej węglowodorami
2016
Usuwanie produktów ropopochodnych ze skażonej gleby jest trudnym procesem, wymagającym uwagi oraz stałej kontroli. W pracy podjęto próbę określenia wpływu techniki dawkowania preparatu enzymatycznego na zmiany mikrobiologiczne i przemiany węglowodorów alifatycznych w glebie naturalnie skażonej węglowodorami. Materiał do badań stanowiła gleba naturalnie skażona substancjami ropopochodnymi, w której całkowite stężenie węglowodorów alifatycznych o długości łańcuchów C8-C40 wynosiło 420,1 mg/kg suchej masy. Przeprowadzono doświadczenia wazonowe, dawkując preparat enzymatyczny w odstępach tygodniowych. Kontrolę stanowiła skażona gleba bez dodatku preparatu enzymatycznego. Doniczki inkubowano w t…
Adrb3 adrenergic receptor is a key regulator of human myometrial apoptosis and inflammation during chorioamnionitis1
2008
The pathophysiology underlying preterm labor triggered by inflammatory conditions such as chorioamnionitis remains largely unclear. It has already been suggested that beta-3 adrenergic (ADRB3) agonists might be of interest in the pharmacological management of preterm labor. Although there is evidence implicating ADRB receptors in the control of inflammation, there are minimal data relating specifically to ADRB3. To explore the cellular consequences of chorioamnionitis and detect apoptosis, we first performed immunostaining and Western blot experiments on human myometrial samples obtained from women with confirmed chorioamnionitis. We then developed an in vitro model of chorioamnionitis by i…
The economic causes of the failure of the "socialist" system
1994
Le but de ce travail est de démontrer pourquoi les pays qui se prétendaient socialistes n'ont pas atteint leurs deux principaux objectifs: justice sociale et démocratie. En ce qui concerne le premier, dans ces pays, l'organisation de la production et la détermination des prix, centralement planifiés, nepermettaient pas toujours de réaliser la production en fonction de l'utilité sociale. Cette façon de déterminer les prix engendre une demande sans offre qui se révèle être, d'une part, une cause de dysfonctionnement du système car le marché ne joue pas alors l'un de ses principaux rôles qui est detransmettre l'information aux responsables de la production, d'autre part, une cause d'insatisfac…
Aspetti della produzione dei piccoli ruminanti con impatto sulla salute umana
2011
Negli ultimi anni l’attenzione del consumatore si è sempre più orientata verso le caratteristiche nutrizionali degli alimenti. Queste proprietà sono di grande importanza anche per quanto riguarda le produzioni dei piccoli ruminanti. Il presente lavoro ha lo scopo di riassumere i principali risultati emersi dal progetto di ricerca “Aspetti della produzione dei piccoli ruminanti con particolare impatto sulla salute umana”. Sono stati analizzati mediante i metodi descritti in letteratura: 1) i polimorfismi genetici dei biopeptidi del latte dei piccoli ruminanti; 2) le attività di alcuni enzimi della membrana del globulo di grasso e la frazione lipidica del latte ovino; 3) la qualità nutriziona…
Mujeres productoras de queso de cuajo: contribución de la labor invisible en la reproducción laboral

Crowdfunding performance, market performance, and the moderating roles of product innovativeness and experts' judgment: Evidence from the movie indus…
2023
Reward-based crowdfunding (CF) has emerged as a method to solicit funds for innovative projects. Yet, little is still known about the ability of reward-based CF to act as a signal in the eyes of future consumers, and thus boost the future market performance of new products that innovators intend to commercialize using the campaign funds. In addition, scant research has clarified the boundary conditions that can magnify or weaken the efficacy of this CF signal. Given the relevance of reward-based CF for supporting innovation, understanding when the CF campaign performance works as an effective signal is of great interest, especially in business settings characterized by high product quality …
Evaluation of Clutch Plate Integrity with Non-Destructive Methods
2009
Abstract Nondestructive evaluation (NDE) represents an important phase in the life cycle of a product to detect defects both in service and in production. NDE techniques most commonly used to detect surface defects are visual inspection and methods based on eddy current and ultrasound. Laser and non-contact sensors have been recently used to inspect ultrasonically without contact. Components with complex geometry are usually inspected combining several NDE techniques, or simply visually where analysis and evaluation of results are performed by an operator based on specific parameters of acceptance. This last method is currently used to inspect the clutch plates since their complex geometry,…
