Svrha je ovoga rada bila proizvesti nove prehrambene proizvode obogaćene bioaktivnim sastojcima iz koncentriranog soka od crvenog grožđa, mikroinkapsuliranog pomoću sušenja zamrzavanjem u otopini ...izolata proteina sirutke i kitozana. Dobiven je prah s učinkovitošću enkapsulacije od (86,1±4,0) %, masenih udjela antocijana (izraženih kao ekvivalenti cijanidin-3-O-glukozida) od (1,4±0,2) mg/g, ukupnih polifenola (izraženih kao ekvivalenti galne kiseline) od (3,3±0,6) mg/g i flavonoida (izraženih kao ekvivalenti katehina) od (1,6±0,5) mg/g. Konfokalnom laserskom mikroskopijom otkriveno je da su flavonoidni pigmenti bili umotani u matriks, dok su antocijani tvorili velike i kompaktne nakupine. Mikroinkapsulirani prah je zatim upotrijebljen za proizvodnju želea. Novi prehrambeni proizvodi imali su zadovoljavajući maseni udjel antocijana, i to od (0,03±0,01) do (0,12±0,02) mg/g, dok se udjel flavonoida nije bitno promijenio. Svi želei su imali znatnu antioksidacijsku aktivnost. Rezultati ispitivanja probavljivosti in vitro potvrdili su je da tijekom simulirane probave došlo do polaganog otpuštanja antocijana iz hrane u želucu, a zatim znatnog otpuštanja bioaktivnih sastojaka u crijevima. Dodatak mikroinkapsuliranog praha znatno je smanjio tvrdoću, kohezivnost i elastičnost želea, što je dovelo do destabilizacije strukture gela i smanjenja privlačnih sila između komponenata matriksa. Sensorska analiza pokazala je da su panelisti preferirali uzorak želea pripremljen od grožđanog soka.
U osnovnoj školi kvadratna mreža uglavnom se koristi pri rješavanju geometrijskih zadatka. U članku autor ukazuje i na druge mogućnosti njenog korištenja u nastavi matematike.
Sadržaji izloženi u ...ovome radu, kao cjelina, namijenjeni su prvenstveno radu s onim učenicima osnovne škole koji u matematici žele i mogu više, tj. radu s mladim matematičarima (osnovne škole).
Little research has been done on psychological contract breach situations from the perspective of the breacher, including situations in which potential breach actions were enforced by a third‐party. ...This exploratory study aims to see how enforced breach affects the breacher, their reactions to the situation, and their relationships with community stakeholders. Semi‐structured long‐form interviews with Canadian teachers whose union decided to go on a work‐to‐rule strike, risking relational breaches with school community stakeholders, were undertaken. Teachers experienced negative emotions and engaged in breach mitigating actions. Implications include being aware of the negative effects on unwilling breachers and the relationships with the source of breaches, and the possibility of mitigating breaches while still removing obligations if breachers engage in mitigating actions.
Résumé
Peu de recherches ont été menées sur les situations de rupture de contrat psychologique du point de vue de l'auteur de la rupture et sur les situations dans lesquelles les mesures de rupture potentielle sont appliquées par un tiers. Cette étude exploratoire porte sur l'impact de la mise en œuvre d'une rupture de contrat sur la partie ayant rompu le contrat, les réactions de cette dernière à la situation et ses relations avec les autres parties prenantes. Des entretiens longs semi‐structurés ont été menés auprès d'enseignants canadiens dont le syndicat a décidé de se mettre en grève du zèle, risquant ainsi de provoquer des ruptures relationnelles avec les autres parties prenantes de la communauté scolaire. Les enseignant, ayant ressenti des émotions négatives, ont entrepris des actions d'atténuation de la rupture. Parmi les implications de l’étude, il y a la prise de conscience des effets négatifs de la rupture sur les parties qui ne veulent pas rompre le contrat et les relations avec la source de la rupture, ainsi que la possibilité d'atténuer la rupture tout en supprimant les obligations si les parties qui rompent les contrats entreprennent des actions d'atténuation.
Depuis le début des années 2000, l’Argentine est le théâtre d’un certain renouveau autogestionnaire. Plus de 20ans après la fin de « l’expérience yougoslave », ce pays connaît en effet une vague ...d’occupations et de « récupérations » d’usines par leurs salariés qui suscite l’intérêt des altermondialistes : ces mobilisations incarneraient l’une des alternatives majeures à la globalisation « néolibérale ». En revenant de façon exhaustive sur l’un des cas emblématiques de ces récupérations, cet article montre à l’inverse que ses acteurs agissent au nom d’une relation privilégiée aux dirigeants et d’un « ethos du zèle ». En ce sens, leur lutte et la mise en place de l’autogestion constituent un cas riche d’enseignements pour l’analyse des mobilisations.
Since the turn of the century, Argentina has been the scene of a renewal in “self-management”. More than twenty years after the end of the Yugoslavian experiment, a wave of factory occupations and “recuperations” by their wage-earners has unfurled in this South American land, and aroused the interest of those opposed to globalization. This activism represents a major alternative to “neoliberal” globalization. As this exhaustive examination of a symbolic instance of “recuperation” shows however, those involved undertake their actions in the name of a special relation with company directors and out of an “ethos of zeal”. In this sense, their struggle and the implementation of self-management is an example laden with lessons for analyzing activism.
Plants respond to grazing by herbivorous insects by emitting a range of volatile organic compounds, which attract parasitoids to their insect hosts. However, a positive outcome for the host plant is ...a necessary precondition for making the attraction beneficial or even adaptive. Parasitoids benefit plants by killing herbivorous insects, thus reducing future herbivore pressure, but also by curtailing the feeding intensity of the still living, parasitised host. In this study, the effect of parasitism on food consumption of the 5th instar larvae of the autumnal moth (Epirrita autumnata) was examined under laboratory conditions. Daily food consumption, as well as the duration of the 5th instar, was measured for both parasitised and non-parasitised larvae. The results showed that parasitism by the solitary endoparasitoid Zele deceptor not only reduced leaf consumption significantly but also hastened the onset of pupation in autumnal moth larvae. On the basis of the results, an empirical model was derived to assess the affects on the scale of the whole tree. The model suggests that parasitoids might protect the tree from total defoliation at least at intermediate larval densities. Consequently, a potential for plant-parasitoid chemical signalling appears to exist, which seems to benefit the mountain birch (Betula pubescens ssp. czerepanovii) by reducing the overall intensity of herbivore defoliation due to parasitism by this hymenopteran parasitoid.

Její popisovaná 90% účinnost je vysvětlitelná i rozborem ...účinků jednotlivých složek metodami klasické „západní“ farmakologie. Lze ji také zařadit do managementu chronických výtoků mezi eradikaci patogena a restituci poševního prostředí probiotiky.
A NaturGyn Scarlett vaginal ball contains 8 herbal drugs. It is designed for the treatment of chronic and recurrent conditions of vaginal discomfort. Its described 90% efficacy can also be explained, based on the analysis of effects of its individual components, using the methods of conventional Western pharmacology. It can also be included in the management of chronic discharge, between eradication of pathogens and restoration of vaginal environment with probiotics.
