O leite é um dos produtos que mais contribuíram para a economia brasileira e apresenta alto valor nutritivo, composto por 87% de água e 13% de sólidos como gordura, proteína, lactose, sais minerais e vitaminas. Por possuir tantos nutrientes ele se torna um ótimo meio de cultura para microrganismos, o que pode acarretar em prejuízos tanto para a indústria como para o consumidor, sendo assim é de suma importância garantir a sua qualidade. Uma das formas de avaliar a qualidade do (...) leite cru refrigerado é observando a contagem bacteriana total (CBT) ou contagem padrão em placa (CPP). A CBT pode ser influenciada por diversos fatores, dentre eles o tempo e a temperatura de armazenamento do leite. Nesse contexto, o presente trabalho objetivou verificar como a temperatura e o tempo de armazenamento podem influenciar na contagem bacteriana total e no teor de sólidos do leite cru refrigerado. O trabalho foi realizado a partir da coleta de 6 amostras de leite recém ordenhado em uma fazenda localizada em Granada, distrito de Abre Campo – MG, e analisadas num período de 48 horas no Laboratório do Hospital Veterinário Gardingo. As amostras apresentaram crescente aumento na contagem padrão em placa desde a primeira análise após a coleta do leite, mesmo com a temperatura de armazenamento dentro do limite estabelecido pela legislação e relativa homogeneidade nos teores de sólidos.

Based on the analysis of the accumulated experimental data and on the informational concepts of the Informational Model of Consciousness (IMC), in this article is presented an informational modeling of the operability of the posterior cingulate cortex (PCC). Examination of the experimental results obtained with the modern non-destructive, high spatial resolution investigation tools to study the functional characteristics of the PCC and associate metabolic processes, shows mainly that this is involved in the large scale default mode network (DMN), composed primarily (...) by PCC, medial prefrontal cortex (MPFC), and the inferior parietal lobe (IPL), displaying an increased activity under passive task conditions (i.e. negative mode). This operability mode is in an opposing balance with attention and task performances mode, acting thus as a disruption process. One of the main conclusions is that the PCC cognitive orientation is primarily focused on the self person or on the “self” (I) projected from others, in “daydreaming” or “mind-wandering" wakeful rest, involved in present or future virtual projects. In spite of these advances, the particular role and specific functions of PCC are not yet fully understood, PCC remaining an enigmatic/contradictory structure of the brain, not included up to date in any brain model, so the PCC informational modeling presented here in terms of IMC covers this lack. IMC assigns to the brain the fundamental role of informational processor, composed by various operating structures according to specific objectives synthetically expressed by seven main cognitive centers of “self" (I) as: Iknow (memory), Iwant (decision), Ilove (emotions), Iam (self-status), Icreate (genetic transmission), Icreated (genetic inheritance), Ibelive (info-selection), assuring the info-connectivity with the body and external/internal world, the adaptability (learning process) and survival. It is deduced in this way that the specific behavior of PCC according to its intermediary architectural position between the vital central region of the brain, connecting the mind with the external/internal reality, is that of a moderator/integrator hub/informational YES/NO switcher from the external/awake captured focusing information to the internal accumulated experience of life, used as a valid reference. Therefore, the specific operability of PCC in terms of cognitive centers is that of an informational switcher, mainly operating with Iknow/Iwant to explore the self-status reflected in Iam, within day-dreaming/imaginary virtual sceneries.

Introduction: the objective of this investigation is to analyses the advances of understanding in the epigenetic processes and to extract conclusions concerning the information-based evolution from the perspective of the Informational Model of Consciousness (IMC). Analysis of epigenetic mechanisms: it is shown that the study of the epigenetic mechanisms are of increasing interest not only to discover the responsible mechanisms of some diseases, but also to observe the acquisition and transmission mechanisms of some traits to the next generation/ transgenerations, without (...) affecting the DNA sequences. These advances were especially supported by the spectacular progresses in the high technological tools like digital microfluidic techniques and semiconductor-based detection systems, allowing to apply sequencing methods of DNA and to observe its structural modifications. The specific typical steps of the epigenetic mechanisms are analysed, showing that these mechanisms could be fully described in terms of information, as signal transmission agents embodying or disembodying information in three different stages and under specific conditions, including especially the signal persistence as a main conditional epigenetic factor. Results concerning the information-assisted evolution from the perspective of IMC: the epigenetic mechanisms are discussed as a function of each component of the informational system of the organism, consisting in memory, decisional operability, emotional reactivity, metabolic driving processes, genetic transmission, genetic info-generator and the info-connection explaining the special extra-power properties of the mind. It is shown that the epigenetic mechanisms could be related to the specific functions of each informational component, mainly exhibiting five levels of integration of information as matter-related information, culminating with the stable integration in the procreation cells and transmission to the next generation. The results were extended to explain the transgenerational adaptive processes of isolated population groups. Conclusion: the epigenetic mechanisms discussed within IMC allow to understand the transgenerational adaptation as an information-assisted proces. (shrink)

At the invitation of the Commission for World Mission and Evangelism (CWME) of the World Council of Churches (WCC) in collaboration with different associations involved in mission and ecumenical studies, the Regional Center for Central and Eastern Europe convened at the Faculty of Orthodox Theology of the Babes-Bolyai University, Cluj-Napoca, Romania, through its Center for Mission and Nomocanonical Studies (CMNS, in collaboration with the Central and Eastern European Association for Mission Studies (CEEAMS). Its aim was to reflect on how the (...) International Missionary Council (IMC) has influenced mission theology and practice in Central and Eastern Europe, taking into account different contextual realities. (shrink)
