At the Beginning of a Long Way

The publication of a new scientific journal cannot surprise anyone in a period when the innovative role of science is unanimously recognized. This editorial event belongs to the normal evolution of this eternal area of human preoccupations. Scientists’ research results are first to be made known to those directly involved in disclosing the mysteries of nature and society and then also to those who apply them in the economic, political, and social practice.

A NMDA receptor antagonist, MK-801 impairs consolidating extinction of auditory conditioned fear responses in a Pavlovian model.

A NMDA receptor antagonist, MK-801 impairs consolidating extinction of auditory conditioned fear responses in a Pavlovian model.

Two way ANOVA showed significant effects of protocol [F(2, 144) = 3.655, p,0.05], day [F(5, 144) = 79.778, p,0.01] and interaction between protocol and day [F(8, 144) = 2.562, p,0.05] (Fig. 2A) on the percentage of entries into OA (Fig. 3A). Two way ANOVA also showed no significant effects of protocol [F(2, 144) = 2.523, p.0.05], but significant effects of day [F(5, 144) = 72.166, p,0.01] and interaction between protocol and day [F(8, 144) = 6.166, p,0.01] (Fig. 2A) on the percentage of time spent in OA (Fig. 3B). Post hoc test indicated that there is no difference between groups (P.0.05). Thus, the significant effects of interaction between protocol and day originated mainly from the source of day. Taking together, our data indicated that the general anxiety behaviors were decreased along with the experiment and the daily general anxiety behavioral patterns in Imme EXT and EXT groups were similar to those of Fear group (Fig. 3). Figure 2. Experiment 2: Freezing score measured in rats receiving different treatments. The freezing score were measured before the experiment (baseline), on the fear conditioning day (Fear) or during the retention tests (R 1, 3 and 7 d). Fear, conditioned fear rats underwent forgetting; EXT, conditioned fear rats underwent delayed extinction (beginning at 24 h post-conditioning); MK-801 + EXT, rats subjected to the delayed extinction trials and MK-801 was i.p. injected at the dose of 0.3 mg/kg 40 min before the extinction; EXT + MK-801 (4 h), rats subjected to the delayed extinction and MK-801 was i.p. injected at the dose of 0.3 mg/kg 4 h after the extinction; EXT + MK-801 (12 h), rats subjected to the delayed extinction and MK-801 was i.p. injected at the dose of 0.3 mg/kg 12 h after the extinction; EXT + Veh, rats subjected to the delayed extinction and 0.1 M PB (the volume was calculated according to the body weight) were injected at 4 h after the last extinction trial; Veh + EXT, Optimal volume of 0.1 M PB were injected and 40 min later, these rats were subjected to the delayed extinction.

#firstworldproblems: When Long Films Last Even Longer

#firstworldproblems: When Long Films Last Even Longer

In some senses, then, the failure of the apparatus reminds us not of its subservience to us, but of our subservience to it; it involves a feeling of humiliation on our part for the very reason that our hubristic sense of domination over the apparatus has been exposed as sham. We do not dominate the apparatus. Rather, we are slaves to the capitalist quantification/evaluation of time as money (“busi- ness”), and we know it. This awareness of our subservience has been exposed rather than quietly ignored through the use of media, which we use precisely to avoid having to recognise our subservient condi- tion. It is because of the shame involved in this exposure of our subservience that we immediately try to confess the very first world nature of the problem of our annoyance at the Internet not functioning properly. In confessing that it is a “first world problem,” we clearly demonstrate that we are invested in – and are happy to perpetuate – a world that has been divided into at least three parts, such that the first and the third world are not conjoined, inter- dependent, or what I might, after Karen Barad (2007), term entangled. Instead, they are separate and hierarchical, so much so that we make up a ghostly “second world” that acts as a buffer be- tween the first and third worlds, rather than having them rub up against each other, reminding each other of their existence. This confession of the “first world problem” in turn bespeaks our shame that we know that our first world is dependent upon – and that we who inhabit this first world are therefore subservient to – that third world and not the other way around. This confession comes as we simultaneously deny (by saying that the third world is not our world, and that our world is split in three rather than one) and for- get (by ignoring the third world and preferring to look at our media machines) its truth.

PHENOLOGY AND YIELD OF THE ‘ROXO DE VALINHOS’ FIG CULTIVAR IN WESTERN POTIGUAR

PHENOLOGY AND YIELD OF THE ‘ROXO DE VALINHOS’ FIG CULTIVAR IN WESTERN POTIGUAR

ABSTRACT - The ‘Roxo de Valinhos’ fig is one of the most widely grown varieties in the world, however, there are still few studies on the phenology and yield of fig trees, especially in semi-arid regions. This study evaluated the phenology and yield aspects of the ‘Roxo de Valinhos’ fig cultivar in Western Potiguar. The experiment was carried out from July to December 2015 in the didactic orchard of the Federal Rural University of the Semi-Arid, UFERSA. The following phenological aspects were analyzed: pruning at the beginning of budding, emergence and maturity of the first fruit, beginning of harvest, length and diameter of branches, number of fruits per branch, length and diameter of fruits, absolute growth rate, yield per plant, number of fruits per plant, and fruit weight. We used descriptive statistics; for quantitative and qualitative characteristics, we used regression analysis and means test, through Tukey´s test at 5% probability. Fig trees showed good adaptability to semi-arid regions and precocity when compared to fig trees from temperate regions, in all phenological stages; the studied cultivar showed promising results for cultivation in this region.

Green Facade As A Prototype Way Of Extending Natural Sphere In A Hyper Dense Urban Context.

sustainable solution to protect the environment and the earth even ourselves, against pollution, squandering of natural resources and global warming just to mention the few all this are the result of negative human activities. According to this research is evadable that vertical greenery can be a sustainable tool remedy due to its capability not only on environmental benefits but widely spread to reducing indoor temperature, have many economic benefits. Green façades can be an alternative tool of sustainable architecture due to its capability of enriches the biodiversity of the flora and fauna. According to three case studies green façade proof to protect interior living space from acoustic pollution, dust particles harsh winds and direct sunlight and all this has direct or indirect benefits. On the other and green facades can be expanse in both short and long term if key issues are not properly considered in design and construction phases. They is need for wider research on how plants and species can survive on this high rise structure which are increasingly gaining more heights. Why more research because as it steady they is plenty of sci entific reasons why skyscrapers don‘t and won‘t have trees, at least not to the height which, many architects are currently proposing and other building. It is hot, cold, windy the rain lashes at high velocity same as snow. Life for city trees can be hard enough at the ground level what more miles above it, where nearly every climate variable more extreme than at street level. While another challenge is for trees to find enough space for their roots on balconies. Applying vertical greenery systems for different purpose particular attention has to be considered such as selection of plants, local climate maintenance consideration. The properties of the plant should be examined or well defined in deferent seasons so as to maximize the benefits after installation. Orientation is very import since it will affect the growth and plant behavior as well.

Road March Searching a Better Alternative Way of Hartal Culture in Bangladesh

Road March Searching a Better Alternative Way of Hartal Culture in Bangladesh

Hartal emerged in the political arena of Bangladesh to secure the demand of political party’s interest in the name of people’s demand. It was vastly used to overthrow autocratic regime during Ershad’s period. A series of hartals were carried out by the political parties to achieve the goal of parliamentary democracy. It also contributed to bring a unique form of Non- Party Caretaker Government in 1996. Although people supported hartals to overthrow dictator Ershad, it became more violent after the restoration of parliamentary democracy. The number of hartals was raised sharply over the periods of 1991 and 2006. .It became the tools of political parties only. They used hartal for their own interests. Political activists vandalize public properties during hartal. They also create chaotic situation which is really harmful for our economy. Businessmen and farmers suffer more as they fail to sell or buy their products. Thus, hartal has become as an agony to the people. On the backdrop, various organizations, civil society and people from all walks of life have raised their voice to ban the culture of hartal and to induce new culture such as long march, human wall and road march etc. According to the survey report of ORG-Quest Research Limited (2009), around 59% of respondents believed that the culture of hartal would not come back again in Bangladesh politics. The opinion slightly decreased in 2010. Almost 53% of respondents believed that the culture of hartal would not return in future (Prothom Alo, January 6, 2012).People’s tidal opinion against hartal made political parties to think about their destructive programs. After the bitter experience of political parties as well as masses on January 11 in 2007, offensive programs like hartal lost its popularity completely. During the present regime, the opposition called number of hartals which have been failed

SHORT AND LONG-TERM EFFECTS OF A CHILD- LABOR BAN

SHORT AND LONG-TERM EFFECTS OF A CHILD- LABOR BAN

discontinuity design to estimate the impact of the ban at different points of individuals’ life-cycles. Our estimates show that the ban reduced incidence of boys in paid work activities by 4 percentage points or 46 percent. We find that the fall in child labor is mostly explained by the change in the proportions of boys working for pay and studying and observe an increase in the proportion of boys only studying as a consequence. The results suggest that the ban re duced boys’ participation in the labor force. We follow the same cohort affected by the ban over the years and find that these short-term effects persisted until 2003 when they turned 18. We pooled data from 2007 to 2014 to check whether the ban affected i ndividuals’ stock of human capital and labor-market

Tur ning to what is really important, it should be noted that industrial production fell in the last quarter of 2008 but demand for consumer goods underwent a slight fluctuation and then grew at an accelerated rate, as a result of the government stimulus. The contraction of credit led to an abrupt halt in investment and production but the final consumer demand was hardly affected. In other words, on reaching Brazil, the financial panic, had an impact on the supply side through strong credit restrictions, but did not reach the point of affecting consumers. This fact explains why today we have an extremely dynamic domestic market and, more importantly, that this dynamism was caused in an endogenous way.

Educ. Real. vol.42 número4

The São Joaquim seminary is an establishment of public cha- rity, aimed to gather up orphan and disfavored boys, so that they can be there educated conveniently, and qualified to the exercise of honest and beneficial tasks (Brasil, 1878, p. 62). Throughout the 19th century, several other institutions were cre- ated with the same purpose to conciliate teaching and learning of a craft. We can highlight the regulation, from 1840 on, of the education of orphans and babies found in baby hatches in Arsenals of War and of the Navy as apprentice children, the creation of agricultural colonies soon after the Lei do Ventre Livre (Brasil, 1871) [providing that all children born from slaves who were pregnant at the time would be free since bir- th], of schools of arts and crafts, patronages and agricultural institutes and vocational schools in the 20th century (Marcílio, 1998). It is impor- tant to stress that, despite the long tradition of the presence of the State in the assistance to the disfavored childhood, this action was a part- nership with religious institutions, individual initiative, philanthropic institutions, founded by doctors and jurists among others, making to emerge a range of institutions: asylums, schools of orphans, houses for handicraftsmen learners, philanthropic associations etc.

CONTINUOUS CREATION IN THE PROBABILISTIC WORLD OF THE THEOLOGY OF CHANCE

CONTINUOUS CREATION IN THE PROBABILISTIC WORLD OF THE THEOLOGY OF CHANCE

The principle of divine control is very important in discussions con- cerning the relation between the Creator and His creatures. These seem to be based on two assumptions. The irst assumption is that God can achieve all His purposes in the created world (divine providence) if and only if He controls every existing being. Therefore, divine control must be perfect and unrestricted (divine volitions must be determined in every respect). Maximal possible control consists in the fact that God creates ex nihilo every being and subsequently conserves them. The second assumption is Anselmian: God is the greatest possible being one can conceive. A perfect being has everything under its control and a perfect being controls everything in the most perfect way possible. Furthermore, the best way to control everything is to create every being out of nothing and to create it as absolutely depen- dent in existence and nature upon God’s will. Omnipotence thus means to conserve continuously all created beings. Continuous creation is the best way to express divine perfection: perfect power and perfect will. Therefore, all contingent beings exist this or that way as long as divine power is acting and divine will wills itself to act upon a given being.

First continuous ground-based observations of long period oscillations in strato-/mesospheric wind profiles

First continuous ground-based observations of long period oscillations in strato-/mesospheric wind profiles

pected (e.g. compare the results from the Bern and the Provence campaign which were sampled at very close geographical locations) one might also conclude that zonal wind oscillations tend to be strongest at mid latitudes, and that meridional wind oscil- lations are weaker in the tropics than at mid-latitudes. This hypothesis is supported by model data from ECMWF for the time periods of WIRA’s measurement campaigns

THE STUDY OF CHEMICAL TRANSFORMATIONS: AN ANALYSIS OF CONCEPTUAL CHANGE AT THE BEGINNING OF HIGH SCHOOL

THE STUDY OF CHEMICAL TRANSFORMATIONS: AN ANALYSIS OF CONCEPTUAL CHANGE AT THE BEGINNING OF HIGH SCHOOL

In the second meeting (Table 3), the students were presented to the corpuscular model of the matter through a video that showed the observation of the operation of a balloon ride, focusing on the increase in the volume occupied by air after heating and also on the behavior of propane gas stored under pressure in a cylinder. These facts indicate matter as consisting of particles which are in continuous motion and separated by empty spaces. It was proposed that the students take up what was observed in the last activity of the previous meeting in order to re-elaborate their explanations, as well as they were asked to evaluate drawings, supposedly made by other students, to represent the particles that make up the air in a situation where there is variation in pressure in a closed system. Following the presentation of the corpuscular model of matter, students had to analyze a specific situation through the comparison between macro, symbolic and submicroscopic levels of representation. It was observed that they considered the discontinuity of matter and the empty spaces between particles, but disregarded the intrinsic motion of the particles, and presented some confusing ideas as a result of the mixture of individual theories and the new concepts in submicroscopic level.

Investigating The Use Of Mobile Computing In Zimbabwe Polytechnics Case Of A Polytechnic In Zimbabwe

outside staff and lecture rooms, send and receive emails and communicate on social networks. This Polytechnic in particular, was one of the first institutions to install the wireless access points that accessed internet through the main fibre backbone. In 2009 it went on to procure laptops for staff members, starting with senior management, the Heads of departments and finally lectures. Students were then allowed to bring their own devices which could be configured to be able to access institutional WIFI (The Polytechnic ICT policy document, 2010). This was the beginning of mobile computing at the Polytechnic. Since then further strides were made in such areas as installation of applications that run on mobile devices through wireless connections, increasing internet bandwidth to improve speed as demand for internet went up, upgrading wireless access points to improve strength of connectivity, upgrading of servers to handle the demand and volumes and expansion of campus area network to cover the whole Polytechnic, procurement of more mobile devices. And the institution now boasts of such things as e-learning, m- learning, m-education, among other technologies that are giving it a competitive advantage over sister Polytechnics.
