Progress in the development of mesoporous solid acid and base catalysts for converting carbohydrates into platform chemicals

This chapter provides a general overview of recent studies on catalytic conversion of fructose, glucose, and cellulose to platform chemicals over porous solid acid and base catalysts, including zeolites, ion-exchange resins, heteropoly acids, as well as structured carbon, silica, and metal oxide materials. Attention is focused on the dehydration of glucose and fructose to HMF, isomerization of glucose to fructose, hydrolysis of cellulose to sugar, and glycosidation of cellulose to alkyl glucosides. The correlation of porous structure, surface properties, and the strength or types of acid or base with the catalyst activity in these reactions is discussed in detail in this chapter.

Az ipari parkok szerepe a kínai - magyar gazdasági kapcsolatok fejlesztésében (Industrial parks in the development of Hungarian – Chinese economic relations)

A kínai-magyar gazdasági kapcsolatoktól mindenki sokat várt eddig, de viszonylag kevés növekedési hatást sikerült elérnie Magyarországnak a dinamikusan felemelkedő kínai gazdaságból. A tanulmány azt vizsgálja, hogy az ipari parkok, logisztikai bázisok terén mi teheti vonzóvá Magyarországot az EU piacát megcélzó kínai vállalatok számára, illetve milyen gazdasági lehetőségek rejlenek az ipari parkok hálózatában ahhoz, hogy a kínai növekedési dinamika valamennyire érvényesüljön a magyar gazdaságban is. / === / Most of the economic and political actors in Hungary have expected high benefits from the Chinese – Hungarian economic relations, but only moderated growth impact has been imported from the dynamic emerging Chinese economy. The study surveys the potentials of industrial parks and logistic bases whether how much they can add to the attractiveness of Hungary toward the Chinese companies targeting the single market of the EU, and what range of economic opportunities is exploitable in the network of industrial parks for having the Chinese growth dynamics to prevail particularly in the Hungarian economy.

A karcsú (lean) elvek alkalmazásának tapasztalatai az egészségügyi folyamatok fejlesztésében (Experiences of the adaptation of lean management in the development of healthcare processes)

Az elmúlt néhány évben a külföldi sajtóban és szakmai publikációkban egyre többször jelenik meg a „lean egészségügy”, azaz a karcsú menedzsment alkalmazása az egészségügyben mint téma. Habár az ez irányú kutatások még nemzetközi szinten is csak legfeljebb a hajnalukon tartanak, Magyarországon még szinte teljes a sötétség. Ennek a cikknek az a célja, hogy egyrészről felhívja a kutatók, de még inkább a egészségügyi dolgozók, menedzserek figyelmét erre a menedzsmenteszközre és filozófiára, mely új lehetőségeket kínál, másrészről, hogy áttekintést adjon a területen végzett nemzetközi kutatások eredményeiről. A tanulmány ennek megfelelően alapvetően két részre bontható. Az első felében az egészségügyi szolgáltatások helyzetének rövid jellemzése után a karcsú menedzsment alapjait és az egészségügyi szolgáltatásokban való alkalmazásának eszményét mutatja be. A második fele ugyanakkor 16 esettanulmány elemzésén keresztül bemutatja, hogy meddig jutott a világ a „lean egészségügy” ideájának megvalósításában. _______ In the past few years “Lean Healthcare” – the adaptation of lean management into healthcare settings – turns up as a topic often and often in foreign press and the in the professional publications. Although researches at international level in this field are at best at their dawning, in Hungary the darkness is almost complete. This article aims at one side to draw researchers’ and even more healthcare employees’ and managers’ attention to this management tool and philosophy, which offers new possibilities. From the other side to provide an overview of the results of the researches conducted in this field. Reflecting this doubled aim the study is divided into two major sections. In the first part the situation of the health care providers is shortly described followed by the introduction of the basics of the lean management and the idea of applying it into healthcare services. While the second part of the study shows how far the World reached in realizing the idea of “Lean Healthcare” by analyzing 16 cases.

Anxiety sensitivity in children and the development of panic and anxiety in adolescents: A prospective study

Research with adult samples has identified a cognitive risk factor for the development of panic and other anxiety disorders in the concept of anxiety sensitivity. The research to date on anxiety sensitivity in children, using the Childhood Anxiety Sensitivity Index (CASI), suggests that the CASI may help to garner knowledge regarding the development of anxiety sensitivity and also help to understand the development of panic attacks, panic disorder and other anxiety disorders in youth. To examine the development of anxiety sensitivity and its relation to panic in youth, data were collected on 44 children in 1998 who were administered the CASI in 1991. Results indicated that children whose CASI scores increased from Time 1 to Time 2 were significantly more likely to report experiencing panic attacks than children whose CASI scores decreased from Time 1 to Time 2. Specifically, 64% (9/14) of children whose CASI scores increased from Time 1 to Time 2 reported having one or more panic attacks versus 36% (5/14) reported having none. Moreover, 72% (21/29) of children whose CASI scores decreased from Time 1 to Time 2 reported no panic attacks. These results suggest that childhood may be the time when anxiety sensitivity as a risk factor for panic and panic disorder is developing. Results are discussed in terms of their relevance for understanding the development of panic and the need for further research to determine the generalizability of these findings in larger samples of children followed over different time spans. ^

4-hydroxy estradiol-induced oxidant-mediated signaling is involved in the development of breast cancer

Breast cancer is a disease associated with excess exposures to estrogens. While the mode of cancer causation is unknown, others have shown that oxidative stress induced by prolonged exposure to estrogens mediates renal, liver, endometrial and mammary tumorigenesis though the mechanism(s) underling this process is unknown. In this study, we show that 4-hydroxyl 17β-estradiol (4-OHE2), a catechol metabolite of estrogen, induces mammary tumorigenesis in a redox dependent manner. We found that the mechanism of tumorigenesis involves redox activations of nuclear respiratory factor-1 (NRF1); a transcriptions factor associated with regulation of mitochondria biogenesis and oxidative phosphorylation (OXPHOS), as well as mediation of cell survival and growth of cells during periods of oxidative stress. Key findings from our study are as follows: (i) Prolonged treatments of normal mammary epithelial cells with 4-OHE2, increased the formation of intracellular reactive oxygen species (ROS). (ii) Estrogen-induced ROS activates redox sensitive transcription factors NRF1. (iii) 4-OHE2 through activation of serine-threonine kinase and histone acetyl transferase, phosphorylates and acetylate NRF1 respectively. (iv) Redox mediated epigenetic modifications of NRF1 facilitates mammary tumorigenesis and invasive phenotypes of breast cancer cells via modulations of genes involved in proliferation, growth and metastasis of exposed cells. (v) Animal engraftment of transformed clones formed invasive tumors. (vi) Treatment of cells or tumors with biological or chemical antioxidants, as well as silencing of NRF1 expressions, prevented 4-OHE2 induced mammary tumorigenesis and invasive phenotypes of MCF-10A cells. Based on these observations, we hypothesize that 4-OHE2 induced ROS epigenetically activate NRF1 through its phosphorylation and acylation. This, in turn, through NRF1-mediated transcriptional activation of the cell cycle genes, controls 4-OHE2 induced cell transformation and tumorigenesis.^

Calle Ocho revived : artists studios commemorate the role of Cuban exiles (1960-1973) in the development of Calle Ocho

The purpose of this study was to learn about the historical development of Eight Street in order to use this information in the revitalization of this area with the new migration of artists. This study demonstrated a cyclical pattern prompted by the economical success of the immigrant group. The 1960 Cuban migration brought an era of life to Eight Street. As the Cubans became successful they left the area causing a decline. Presently the area is witnessing a migration of artists that may bring it new life. The thesis retrofits buildings in this area to create a series of artist studios. These studios are designed using elements of 1960 Cuban urbanity, an era of robust urban life for this street.

The role of supraspinal excitability in the development of healthy-limb deficits following anterior cruciate ligament injury

In the current study, we examined how supraspinal and spinal excitability were altered bilaterally after unilateral anterior cruciate ligament reconstruction (ACLr). 7 participants with ACLr and 7 healthy controls underwent transcranial magnetic stimulation (TMS) and electrical stimulation. To evaluate supraspinal excitability, resting motor thresholds (RMT) and motor evoked potential (MEP) stimulus response curves (SRC) were used. To measure spinal excitability, H-reflex SRC gain was assessed. Mixed factorial ANOVAs were used to compare measures between limbs and between groups. Cohen’s d was used to assess effect sizes between groups. Data indicated no significant differences between subject groups or between limbs. However, large effect sizes were found between limbs for H-reflex gain and RMTs suggesting that ACLr can have an effect on some of the variables examined. This study identified decreases in strength in the injured limbs and that subjects with an ACL injury exhibited decreases in spinal and supraspinal excitability of the quadriceps compared to Healthy controls.

The Influence of Creative Tourism on Sustainable Development of Tourism and Reduction of Seasonality – Case Study of Óbidos

Tourism remains one of the most fast growing and important industries in the world. It is hard to underestimate the importance and the spectrum of the benefits that tourism provides. On the other hand, nowadays, the increasing growth of tourism poses a range of challenges and problems that need to be solved. These challenges resonate in the emergence of the so called 'alternative' or sustainable forms of tourism, which deem to be an antidote against the harms the traditional forms of tourism cause to the environment and local communities. These new forms of tourism, among which is creative tourism, are reinforced by the new breed of tourists, who are no longer satisfied with the static offer of tourism but rather prefer the dynamic one. The present research shows on the case of Óbidos the potential of creative tourism to meet these new needs of modern tourists while also solving number of problems that many destinations face, namely seasonality in tourism, as well as how creative tourism contributes to the sustainable development of tourism.

The Influence of the Family in the Development of Talent in Sport

The purpose of the present study was to describe patterns in the dynamics of families of talented athletes throughout their development in sport. Four families, including three families of elite rowers and one family of an elite tennis player were examined. The framework provided by Ericsson, Krampe, and Tesch- Römer (1993) to explain expert performance served as the theoretical basis for the study. Ericsson et al. suggested that the acquisition of expert performance involves operating within three types of constraints: motivational, effort, and resource. In-depth interviews were conducted with each athlete, parent, and sibling to explore how they have dealt with these three constraints. A total of 15 individual interviews were conducted. Results permitted the identification of three phases of participation from early childhood to late adolescence: the sampling years, the specializing years, and the investment years. The dynamics of the family in each of these phases of development is discussed

The Worsening of the employment and work conditions and its relationship to the self-perceived health in European working population. Relevance and effects of the latest socioeconomic crisis

The recent crisis of the capitalistic economic system has altered the working conditions and occupations in the European Union. The recession situation has accelerated trends and has brought transformations that have been observed before. Changes have not looked the same way in all the countries of the Union. The social occupation norms, labour relations models and the type of global welfare provision can help underline some of these inequalities. Poor working conditions can expose workers to situations of great risk. This is one of the basic assumptions of the theoretical models and analytical studies of the approach to the psychosocial work environment. Changes in working conditions of the population seems to be important to explain in the worst health states. To observe these features in the current period of economic recession it has made a comparative study of trend through the possibilities of the European Working Conditions Survey in the 2005 and 2010 editions. It has also set different multivariate logistic regression models to explore potential partnerships with the worst conditions of employment and work. It seems that the economic crisis has intensified changes in working conditions and highlighted the effects of those conditions on the poor health of the working population. This conclusion can’t be extended for all EU countries; some differences were observed in terms of global welfare models.
