    Halbert, Hannah

    2016-01-01

    The number of people attempting and passing the GED has plummeted. The Ohio economy is tough on low-wage workers with limited formal education. Without a high school diploma, it is virtually impossible to get a family-supporting job. But the GED has become a barricade, blocking Ohio workers from career goals, instead of a launching pad.

  2. Airborne plutonium transported during southwesterly winds near the Hanford Prosser Barricade

    International Nuclear Information System (INIS)

    Sehmel, G.A.

    1980-01-01

    Airborne plutonium could result from resuspension of nuclear-weapons-testing stratospheric fallout deposition. To determine this possible resuspension at the Hanford site, two field experiments between April 12 to june 29, 1976 and August 12, 1976 to January 11, 1977 were conducted near the Prosser Barricade in the Hanford area about 19 to 22 km southeast (140 0 to 160 0 ) of the fuel-processing areas. The primary objective of these experimentss was to determine if stratospheric fallout resuspension was reflected by airborne plutonium concentrations increasing with increasing wind speed. A secondary objective was to confirm the source of the airborne plutonium by determining the plutonium-240 isotopic content or the plutonium-240/plutonium-239-mass ratio. Stratospheric fallout can be identified by the ratio of 240 Pu to other plutonium isotopes in surface soils. Plutonium was transported during southwesterly winds during the two study periods at the Prosser Barricade. Airborne 239 240 Pu concentrations varied as powers of wind speed (U):U -0 2 to U 7 8 . The airborne solids content ranged from 6 x 10 -8 to 1.7 x 10 -6 μCi/g. The 240 Pu isotopic content ranged from 5.6 to 8.1 atom percent and the 240 Pu/ 239 Pu mass ratio ranged from 0.065 to 0.089. The estimated fraction of stratospheric fallout plutonium in these samples was less than 0.24. The remaining airborne plutonium was probably of Hanford origin. Airborne plutonium probably represents resuspension of plutonium from undetermined sites by mechanisms and events not clear at present. An increasing airborne plutonium concentration with increasing wind speed might be expected for an upwind resuspension source(s). However, the geographical source(s) location was not investigated in this study

    During November and December 1983, soil samples were collected by Pacific Northwest Laboratory for hydrologic characterization of the partially saturated (vadose) zone sediments from five wells drilled near the Hanford Wye barricade, about 15 km northwest of Richland, Washington. The samples were taken from each of five boreholes in 1.5-m segments down to the water table or to a depth where further drilling became impossible, whichever was deeper. The samples were collected and handled in such a manner as to minimize water loss through evaporation. The field moisture content was determined for each sample, and for three of the five boreholes the water potential at the field moisture content was also measured. Other characterization included textural analysis, water retention characteristics, hydraulic conductivity, and soil chemistry. From the laboratory data, travel time (i.e., the time necessary for water to move a distance of 43 m, from the soil surface to the ground water) estimates were calculated: they range from 600 years for annual water influx rates that ranged from 0.5 to 5.0 cm/yr. The soil properties determined in this study will aid in modeling the transport of water and chemicals (e.g., radionuclides) to the ground water at the Hanford site

    On February 15, 2017, a DESHF-STO HPFC (health physics field coordinator) was asked by an NEN-1 employee if they could move an instrument, a radiation dosimetry system, from A166A to another lab at TA-35 Building 2. The HPFC walked the job down and discovered the instrument was connected to power. The instrument had not been connected to power previously. See photo 1. The instrument is located within an RCA (radiological control area). Entry to connect the instrument to power the instrument requires contacting RP. RP personnel had not been contacted as required as stated in the RCA posting.

  6. Moving the Barricades to Physical Activity: A Qualitative Analysis of Open Streets Initiatives Across the United States.

    Ciclovía, or Open Streets initiatives, are events where streets are opened for physical activity and closed to motorized traffic. Although the initiatives are gaining popularity in the United States, little is known about planning and implementing them. The goals of this paper are to explore the development and implementation of Open Streets initiatives and make recommendations for increasing the capacity of organizers to enhance initiative success. Phenomenology with qualitative analysis of structured interviews was used. Study setting was urban and suburban communities in the United States. Study participants were organizers of Open Streets initiatives in U.S. cities. Using a list of 47 events held in 2011, 27 lead organizers were interviewed by telephone about planning, implementation, and lessons learned. The interviews were digitally recorded and transcribed. A phenomenologic approach was used, an initial coding tool was developed after reviewing a sample of transcripts, and constant comparative coding methodology was applied. Themes and subthemes were generated from codes. The most common reasons for initiation were to highlight or improve health and transportation. Most initiatives aimed to reach the general population, but some targeted families, children, or specific neighborhoods. Getting people to understand the concept of Open Streets was an important challenge. Other challenges included lack of funding and personnel, and complex logistics. These initiatives democratize public space for citizens while promoting physical activity, social connectedness, and other broad agendas. There are opportunities for the research community to contribute to the expanse and sustainability of Open Streets, particularly in evaluation and dissemination.

  14. Innovation as Road Safety Felicitator

    Sahoo, S.; Mitra, A.; Kumar, J.; Sahoo, B.

    2018-03-01

    Transportation via Roads should only be used for safely commuting from one place to another. In 2015, when 1.5 Million people, across the Globe started out on a journey, it was meant to be their last. The Global Status Report on Road Safety, 2015, reflected this data from 180 countries as road traffic deaths, worldwide. In India, more than 1.37 Lakh[4] people were victims of road accidents in 2013 alone. That number is more than the number of Indians killed in all the wars put together. With these disturbing facts in mind, we found out some key ambiguities in the Indian Road Traffic Management systems like the non-adaptive nature to fluctuating traffic, pedestrians and motor vehicles not adhering to the traffic norms strictly, to name a few. Introduction of simple systems would greatly erase the effects of this silent epidemic and our Project aims to achieve the same. It would introduce a pair of Barricade systems to cautiously separate the pedestrians and motor vehicles to minimise road mishaps to the extent possible. Exceptional situations like that of an Ambulance or any emergency vehicles will be taken care off by the use of RFID tags to monitor the movement of the Barricades. The varied traffic scenario can be guided properly by using the ADS-B (Automatic Detection System-Broadcast) for monitoring traffic density according to the time and place.

  15. The application of an action system model to destructive behaviour: the examples of arson and terrorism.

    Science.gov (United States)

    Fritzon, K; Canter, D; Wilton, Z

    2001-01-01

    This article argues that criminal and deviant behaviour can be productively viewed through an action system framework. The idea is developed by considering two forms of destructive behaviour: arson and barricade-hostage terrorist incidents. Two studies are presented. The first study tests the hypothesis that different forms of arson will reflect the four dominant states that an action system can take; integrative, expressive, conservative, and adaptive. A smallest space analysis was performed on 46 variables describing 230 cases of arson and the results identified the four themes of action system functioning. An examination of the personal characteristics of the arsonists also produced four variable groupings and a combined analysis of the four action scales and four characteristics scales also supported the structural hypothesis of the action system model. The second study applied the action system model to the study acts of terrorist barricade-hostage incidents. A smallest space analysis of 44 variables coded from 41 incidents again revealed four distinct forms of activity, which were psychologically similar to the four modes of arson identified in study one. Overall, these two studies provide support for the appropriateness of the action system framework as a way of classifying different forms of deviant behaviour. Copyright 2001 John Wiley & Sons, Ltd.

  16. Sibling comparison of differential parental treatment in adolescence: gender, self-esteem, and emotionality as mediators of the parenting-adjustment association.

    Science.gov (United States)

    Feinberg, M E; Neiderhiser, J M; Simmens, S; Reiss, D; Hetherington, E M

    2000-01-01

    This study employs findings from social comparison research to investigate adolescents' comparisons with siblings with regard to parental treatment. The sibling comparison hypothesis was tested on a sample of 516 two-child families by examining whether gender, self-esteem, and emotionality-which have been found in previous research to moderate social comparison-also moderate sibling comparison as reflected by siblings' own evaluations of differential parental treatment. Results supported a moderating effect for self-esteem and emotionality but not gender. The sibling comparison process was further examined by using a structural equation model in which parenting toward each child was associated with the adjustment of that child and of the child's sibling. Evidence of the "sibling barricade" effect-that is, parenting toward one child being linked with opposite results on the child's sibling as on the target child-was found in a limited number of cases and interpreted as reflecting a sibling comparison process. For older siblings, emotionality and self-esteem moderated the sibling barricade effect but in the opposite direction as predicted. Results are discussed in terms of older siblings' increased sensitivity to parenting as well as the report of differential parenting reflecting the child's level of comfort and benign understanding of differential parenting, which buffers the child against environmental vicissitudes evoking sibling comparison processes.

    2006-01-01

    The expanding use of innovative botanical ingredients in dietary supplements and foods has resulted in a flurry of research aimed at the development and validation of analytical methods for accurate measurement of active ingredients. The pressing need for these methods is being met through an expansive collaborative initiative involving industry, government, and analytical organizations. This effort has resulted in the validation of several important assays as well as important advances in the method engineering procedures which have improved the efficiency of the process. The initiative has also allowed researchers to hurdle many of the barricades that have hindered accurate analysis such as the lack of reference standards and comparative data. As the availability for nutraceutical products continues to increase these methods will provide consumers and regulators with the scientific information needed to assure safety and dependable labeling

    Coles, A.; Hirschboeck, K. K.; Fryberg, S.

    2009-04-01

    Flood risk managers educate the public on the dangers of driving through flooded roadways, yet losses to life and property continue to occur. This study integrates cultural psychology and risk perception theory to explore how culture, psychological processes, and behavior influence one another. Flood risk managers in Tucson, Arizona collaborated in the development of a questionnaire mailed to local residents. Questions regarding levels of trust, self-efficacy, social autonomy, social incorporation, time perspective, and situational factors were analyzed with respect to whether respondents stated that they have or have not driven through a flooded roadway. Respondents' decisions are influenced by the presence of signs and barricades, passengers, risk of personal injury or damage to the vehicle, and the availability of flood-related information. The most influential factor is the prior successful crossing of other vehicles. The results illuminate complex interrelations among the cultural factors and provide considerations for future risk perception research.

  20. Use of the Location Inverse Solution to Reduce Ghost Images

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Through-the-wall imaging (TWI is a difficult but important task for both law enforcement and military missions. Acquiring information on both the internal features of a structure and the location of people inside plays an important role in many fields such as antiterrorism, hostage search and rescue, and barricade situations. Up to now, a number of promising experimental systems have been developed to validate and evaluate diverse imaging methods, most of which are based on a linear antenna array to obtain an image of the objects. However, these methods typically use the backward projection (BP algorithm based on ellipse curves, which usually generates additional ghost images. In this paper, the algorithm using the location inverse solution (LIS to reduce the ghost images is proposed and simulated. The results of simulation show that this approach is feasible.

    Full Text Available In this paper we will present the design and implementation of an ultrasonic non-contact rangefinder with FPGA. This rangefinder can be used in numerous applications, ranging from hardly accessible spaces to electromagnetically polluted environments. The experimental implementations proved to be accurate, portable, and easy to operate. Attributable to their programmable nature, FPGAs are an ideal fit for many dissimilar markets. Even though FPGAs used to be designated for lower speed and complexity designs in the past, today’s FPGAs effortlessly push the 500 MHz performance barricade. Since they bring features, such as embedded processors, DSP blocks, clocking, and high-speed serial at lower prices, FPGAs are a convincing alternative for almost any type of design.

    The Sample Transfer Canister will be used by the Waste Receiving and Processing Facility (WRAP) for the transport of small quantity liquid samples that meet the definition of a limited quantity radioactive material, and may also be corrosive and/or flammable. These samples will be packaged and shipped in accordance with the US Department of Transportation (DOT) regulation 49 CFR 173.4, ''Exceptions for small quantities.'' The Sample Transfer Canister is of a ''French Can'' design, intended to be mated with a glove box for loading/unloading. Transport will typically take place north of the Wye Barricade between WRAP and the 222-S Laboratory. The Sample Transfer Canister will be shipped in an insulated ice chest, but the ice chest will not be a part of the small quantity package during prototype testing

  4. Plutonium concentrations in airborne soil at Rocky Flats and Hanford determined during resuspension experiments

    1978-01-01

    Plutonium resuspension results are summarized for experiments conducted by the author at Rocky Flats, onsite on the Hanford reservation, and for winds blowing from offsite onto the Hanford reservation near the Prosser barricade boundary. In each case, plutonium resuspension was shown by increased airborne plutonium concentrations as a function of either wind speed or as compared to fallout levels. All measured airborne concentrations were far below maximum permissible concentrations (MPC). Both plutonium and cesium concentrations on airborne soil were normalized by the quantity of airborne soil sampled. Airborne radionuclide concentrations in μCi/g were related to published values for radionuclide concentrations on surface soils. For this ratio of radionuclide concentration per gram on airborne soil divided by that for ground surface soil, there are eight orders of magnitude uncertainty from 10 -4 to 10 4 . This uncertainty in the equality between plutonium concentrations per gram on airborne and surface soils is caused by only a fraction of the collected airborne soil being transported from offsite rather than all being resuspended from each study site and also by the great variabilities in surface contamination. Horizontal plutonium fluxes on airborne nonrespirable soils at all three sites were bracketed within the same four orders of magnitude from 10 -7 to 10 -3 μCi/(m 2 day) for 239 Pu and 10 -8 to 10 -5 μCi/(m 2 day) for 238 Pu. Airborne respirable 239 Pu concentrations increased with wind speed for a southwest wind direction coming from offsite near the Hanford reservation Prosser barricade. Airborne plutonium fluxes on nonrespirable particles had isotopic ratios, 240 Pu/ 239 240 Pu, similar to weapons grade plutonium rather than fallout plutonium

    2017-06-01

    Introduction While the concept of community resilience is gaining traction, the role of spontaneous volunteers during the initial response to disasters remains controversial. In an attempt to resolve some of the debate, investigators examined the activities of a spontaneous volunteer group called Nafeer after the Sudan floods around the city of Khartoum in August of 2013. Hypothesis Can spontaneous volunteers successfully initiate, coordinate, and deliver sustained assistance immediately after a disaster? This retrospective, descriptive case study involved: (1) interviews with Nafeer members that participated in the disaster response to the Khartoum floods; (2) examination of documents generated during the event; and (3) subsequent benchmarking of their efforts with the Sphere Handbook. Members who agreed to participate were requested to provide all documents in their possession relating to Nafeer. The response by Nafeer was then benchmarked to the Sphere Handbook's six core standards, as well as the 11 minimum standards in essential health services. A total of 11 individuals were interviewed (six from leadership and five from active members). Nafeer's activities included: food provision; delivery of basic health care; environmental sanitation campaigns; efforts to raise awareness; and construction and strengthening of flood barricades. Its use of electronic platforms and social media to collect data and coordinate the organization's response was effective. Nafeer adopted a flat-management structure, dividing itself into 14 committees. A Coordination Committee was in charge of liaising between all committees. The Health and Sanitation Committee supervised two health days which included mobile medical and dentistry clinics supported by a mobile laboratory and pharmacy. The Engineering Committee managed to construct and maintain flood barricades. Nafeer used crowd-sourcing to fund its activities, receiving donations locally and internationally using supporters

  9. Application of United States Department of Transportation regulations to hazardous material and waste shipments on the Hanford site

    All hazardous material and waste transported over roadways open to the public must be in compliance with the U.S. Department of Transportation (DOT) regulations. The DOT states that the hazardous material regulations (HMR) also apply to government-owned, contractor-operated (GOCO) transportation operations over any U.S. Department of Energy (DOE) site roadway where the public has free and unrestricted access. Hazardous material and waste in packages that do not meet DOT regulations must be transported on DOE site roadways in a manner that excludes the public and nonessential workers. At the DOE Richland Field Office (the Hanford Site), hazardous material and waste movements that do not meet DOT requirements are transported over public access roadways during off-peak hours with the roadways barricaded. These movements are accomplished using a transportation plan that involves the DOE, DOE contractors, and private utilities who operate on or near the Hanford Site. This method, which is used at the Hanford Site to comply with DOT regulations onsite, can be communicated to other DOE sites to provide a basis for achieving consistency in similar transportation operations.

As new forms of social coexistence and relationships are being configured, and new spaces for encounter and conflict are produced, architecture feels that essential questions regarding its activity are being addressed in each and every one of these situations. And yet we seem unable to relate to them and grasp their significance as we repeatedly turn to old metaphors and tools. If modern architecture pursues the modern liberal state techniques of management and administration of life, then recent forms of political action, which claim a new relation to the sensible, demand – and might help develop – a new understanding of architecture. We are moving from technical and disciplinary knowledge towards a critical practice that integrates with the action of the multitude. Starting from a definition of commons as the production of the multitude, we seek not only to understand the spatial dimension of this production, but also to acknowledge space as common.

    2009-04-01

    Ontario Power Generation (OPG) has developed a Waterways Public Safety Program that includes elements such as integrating public safety considerations into normal business practices and decisions; applying conservative decision making principles regarding operations where there are issues of public safety; and seeking partnership opportunities that enhance public safety awareness. The key steps to the public safety risk assessment process include identifying each type of known public interaction at a facility; identifying the hazards associated with those interactions; assigning a rating of likelihood and consequence for each separate public interaction at a facility; and assigning a risk rating, with a risk matrix for each public interaction. OPG now requires that a new public safety risk assessment be completed every 3 years. The risk assessment is a guide to implementing control measures to lower the risk of injury at dam facilities. OPG has adopted the model that every water conveyance structure will have an established hazardous area, typically adjacent to the structure. These areas are delineated with red danger signs and other control measures installed as needed. Yellow signs are used to delineate warning areas where there is a reasonable likelihood of minor injury or where the public may become stranded. As a minimum, OPG uses signage, sluicegate audible alarms, a stepped approach to sluicegate openings and public education. Safety booms and buoys as well as fencing and barricades may be used as additional control measures along with security patrols and video surveillance to target specific public interactions. 6 figs.

    Ontario Power Generation (OPG) has 64 hydroelectric generating stations, 241 dams, and 109 dams in Ontario's registry with the International Commission on Large Dams (ICOLD). In 1986, it launched a formal dam safety program. This presentation addressed the importance of public safety around dams. The safety measures are timely because of increasing public interaction around dams; the public's unawareness of hazards; public interest in extreme sports; easier access by recreational vehicles; the perceived right of public to access sites; and the remote operation of hydroelectric stations. The presentation outlined the OPG managed system approach, with particular reference to governance; principles; standards and procedures; and aspects of implementation. Specific guidelines and governing documents for public safety around dams were identified, including guidelines for public safety of waterways; booms and buoys; audible warning devices and lights; public safety signage; fencing and barricades; and risk assessment for public safety around waterways. The presentation concluded with a discussion of audits and management reviews to determine if safety objectives and targets have been met. figs.

    Full Text Available The scuttle flies (Diptera: Phoridae are important in forensic dipterology, because of their necrophagous habit. They are amongst the first wave of insects visiting human corpses in mechanically barricaded environments; hence their immature stages are generally used for estimation of PMI. The effect of different substrates commonly used for developmental studies was studied to analyze the variation of growth of the thermophilic variety of Megaselia (M. scalaris prevalent in India on GDM, EDM, and SMS (n=3. One approach of PMI estimation depends on larvae collected from the crime scene and comparing them with reference data derived from larval rearing to establish PMI. Results showed that there was a significant variation in avg. length (F(2,111=15.79873, p=0.000000917, width (F(2,111=14.60528, p=0.00000234, and biomass (F(2,111=37.01727, p=0.000000000000482 of the immature stages in the three media and the larvae grow maximally in the SMS medium. The results of the present study thus provide baseline data on the growth and developmental pattern of the Megaselia (M. scalaris, which can be utilized in conjunction with specific geoclimatic reference data, for forensic entomological studies and also for using the phorid as a biocontrol agent of pestiferous insects.

    Iron oxide nanoparticles (IONPs) have been a propitious topic for cancer treatment in recent years because of its multifunctional theranostic applications under magnetic field. Two such widely used applications in cancer biology are gradient magnetic field guided targeting and alternative magnetic field (AMF) induced local hyperthermia. Gradient magnetic field guided targeting is a mode of active targeting of therapeutics conjugated with iron oxide nanoparticles. These particles also dissipate heat in presence of AMF which causes thermal injury to the cells of interest, for example tumour cells and subsequent death. Clinical trials divulge the feasibility of such magnetic nano-carrier as a promising candidate in cancer biology. However, these techniques need further investigations to curtail certain limitations manifested. Recent progresses in response have shrunken the barricade to certain extent. In this context, principles, challenges associated with these applications and recent efforts made in response will be discussed. - Highlights: • Iron oxide nanoparticles offer various modalities in the field of cancer theranostics. • Magnetic field guided targeting and local hyperthermia are two well known modalities in cancer therapy. • These techniques need further investigations to curtail certain limitations manifested. • This review emphasizes the recent efforts carried out to counteract the drawbacks.

  15. Access road from State Route 240 to the 200 West Area, Hanford Site, Richland, Washington: Environmental assessment

    Energy Technology Data Exchange (ETDEWEB)

    1994-02-01

    The US Department of Energy (DOE) proposes to construct an access road on the Hanford Site, from State Route (SR) 240 to Beloit Avenue in the 200 West Area. Traffic volume during shift changes creates an extremely serious congestion and safety problem on Route 4S from the Wye barricade to the 200 Areas. A Risk Evaluation (Trost 1992) indicated that there is a probability of 1.53 fatal accidents on Route 4S within 2 years. To help alleviate this danger, a new 3.5-kilometer (2.2-mile)-long access road would be constructed from Beloit Avenue in the 200 West Area to SR 240. In addition, administrative controls such as redirecting traffic onto alternate routes would be used to further reduce traffic volume. The proposed access road would provide an alternative travel-to-work route for many outer area personnel, particularly those with destinations in the 200 West Area. This proposal is the most reasonable alternative to reduce the problem. While traffic safety would be greatly improved, a small portion of the shrub-steppe habitat would be disturbed. The DOE would offset any habitat damage by re-vegetation or other appropriate habitat enhancement activities elsewhere on the Hanford Site. This Environmental Assessment (EA) provides information about the environmental impacts of the proposed action, so a decision can be made to either prepare an Environmental Impact Statement or issue a Finding of No Significant Impact.

    Full Text Available “The Eighth Day of the Week” The Eighth Day of the Week is a short story by Marek Hłasko revolving around the topic of losing virginity. Literary scholars consider Hłasko as a representative of machismo; a masculine and male-centred narrator. This text analyses and deconstructs the short story defending it as a comprehensive record of misogynist culture written from the perspective of the main female protagonist and not the expression of misogyny of the author himself. The tools of discourse analysis and feminist philosophy applied to Hłasko’s text produce surprising results. Agnieszka – the main female protagonist of the short story – turns out to be a figure of non-conformity universalised by Hłasko, while the virginity and its loss become a part of female fate used by Hłasko as a motif to show the power of society over an individual. Meanwhile Agnieszka struggles for autonomy from domineering cultural patterns and gains it with the help of not so much barricades and spectacular gestures typical for male protagonists as wit, intelligence and trickery.

    Full Text Available South Africa has recently experienced a series of public protests. The common element is that violence is becoming evident in these protests. This article uses the June 2016 protests in the city of Tshwane as an example to address the root causes of such protests. On 20 June 2016, the African National Congress (ANC announced that the city of Tshwane mayoral candidate for the 3 August 2016 municipal elections in South Africa is the former public works minister and ANC National Executive Committee member, Thoko Didiza. Consequently, public protests in the city of Tshwane emerged immediately after this announcement. These public protests were very violent, such as protesters killed one another, burned buses, looted shops and barricaded roads. The root causes of these violent protests are identified as factionalism, tribalism, sexism, economic exclusion and patronage politics. The purpose of this article is a practical theological reflection on the root causes of June 2016 protests in the city of Tshwane. The main aim of this article is a practical theological solution to the general problem of violent protests.

    The U.S. Department of Energy Richland Operations Office is proposing to close the Nonradioactive Dangerous Waste Landfill (NRDWL) and Solid Waste Landfill (SWL) located in the 600 Area of the Hanford Site. The closure of the NRDWL/SWL entails the construction of an evapotranspiration cover over the landfill. This cover would consist of a 3-foot (1-meter) engineered layer of fine-grained soil, modified with 15 percent by weight pea gravel to form an erosion-resistant topsoil that will sustain native vegetation. The area targeted for silt-loam borrow soil sits in Area C, located in the northern central portion of the Fitzner/Eberhardt Arid Lands Ecology (ALE) Reserve Unit. The pea gravel used for the mixture will be obtained from both off-site commercial sources and an active gravel pit (Pit #6) located just west of the 300 Area of the Hanford Site. Materials for the cover will be transported along Army Loop Road, which runs from Beloit Avenue (near the Rattlesnake Barricade) east-northeast to the NRDWL/SWL, ending at State Route 4. Upgrades to Army Loop Road are necessary to facilitate safe bidirectional hauling traffic. This report documents a cultural resources review of the proposed activity, conducted according to Section 106 of the National Historic Preservation Act of 1966.

So it is essential to have a periodic radiological survey in this area in order to check the concentrations of various radionuclide. Apart from this 2004 Tsunami had many devastating effects along the coastal Tamil Nadu. GOM (Especially Rameswaram coast) didn't suffer a lot due to the barricade-like protection given by the island nation Sri Lanka. But reports suggest that northeastern part of the Krusadai Island had noticeable effects due to Tsunami, which interests to study this area. Current study is a preliminary radioactive report on the northern part of the Krusadai Island

    Full Text Available At the beginning of the XXI century Ukrainian art observed activization of the artist’s interest for the political life of the country. The starting point was 2004, marked by protests against unfair elections in the country, the birth of the first “Maidan” and “Orange revolution”. In a number of artistic actions organized by art groups we can see the reflection of the revolution events and, later, the frustrations of its ideals. The most striking manifestation of political issues in contemporary art in Ukraine was the great creativity following the second “Maidan” (2013. In this spontaneous Performance everyone plays a role: the participants are the protesters, official persons, fighters of “Berkut” and interior force troops, journalists and others. Protesters’ tents, barricades, a statue of Lenin and “Maidan” itself (or Independence Square as a place of free will and creativity became the Symbols of the “Maidan” and its own art objects.

    Since 1984, a recuperation program of soils of sedimentary origin has been developed in the farm of Armero of Tolima University, which up to this year (1996) has already shown many a good positive result. To attain such a remarkable effect in the highly deteriorated soils of this farm, it was decided to develop a project for their conservation consisting of the building of terraces, live and dead hedges and barricades, as well as the planting of fruit and forest trees so that, through a well planned methodology, the community members may learn to design, build, maintain and evaluate practical work oriented towards their own know-how and especially to the recuperation of unproductive areas, together with their integration, at due time, with the land and cattle activity. The soil conservation project began in November, 1983, and today, 12 years after having it been worked out, maintained and evaluated, we can see a land wholly recovered, with abundant native vegetation ready for production, mainly with the setting of perennial crops. Bearing in mind these successful results, our recommendation is to continue to implement this project in the different areas where the setting of soil conservation works is necessary, in order that the benefits obtained may be multiplied through the installment of easy and, especially, very economical set-ups

    This safety evaluation report (SER) documents the basis for the US Department of Energy (DOE), Richland Operations Office (RL) to approve the Hanford Sitewide Transportation Safety Document (TSD) for onsite Transportation and Packaging (T&P) at Hanford. Hanford contractors, on behalf of DOE-RL, prepared and submitted the Hanford Sitewide Transportation Safety Document, DOE/RL-2001-0036, Revision 0, (DOE/RL 2001), dated October 4, 2001, which is referred to throughout this report as the TSD. In the context of the TSD, Hanford onsite shipments are the activities of moving hazardous materials, substances, and wastes between DOE facilities and over roadways where public access is controlled or restricted and includes intra-area and inter-area movements. The TSD sets forth requirements and standards for onsite shipment of radioactive and hazardous materials and wastes within the confines of the Hanford Site on roadways where public access is restricted by signs, barricades, fences, or other means including road closures and moving convoys controlled by Hanford Site security forces.

    Full Text Available Althusser's work arrived just when the disintegrating liberal consensus was shaking the ivory towers of the university. Students protested the war in Vietnam as well as the policies of the university. Althusser offered an understanding of this corrupt world and its distorted self-image. These theories provided an exciting new totalization in which life had meaning and intellectuals, a vital role. In literary studies, students and lecturers assumed that works of literature were anti-scientific, preservers of the status quo, without genuine knowledge. Disillusioned, these students and lecturers condemned Literature as an institution and ignored the individual work. To stop teaching the dominant ideology, they found redemption through abstraction—general principles, abstract structures. Academics found it attractive to raise barricades in the mind, not the street. Althusserian ideas showed lecturers and students that what was thought to be a purely literary or factual matter of aesthetic appreciation was really ideological and political, but the arrogance of the Althusserians, who recognized no theory before Althusser and no value in empirical experience, offended potential allies.

  9. Effect of the chemical structure of anion exchange resin on the adsorption of humic acid: behavior and mechanism.

    2015-01-01

    Polystyrenic (PS) anion-exchange resin and polyacrylic (PA) anion-exchange resin were used to investigate the effect of resin chemical structure on the adsorption of humic acid (HA). Due to the rearrangement of HA to form layers that function as barricades to further HA diffusion, PS resin exhibited 12.4 times slower kinetics for the initial adsorption rate and 8.4 times for the diffusion constant in comparison to that of the PA resin. An HA layer and a spherical cluster of HA can be observed on the surface of the PS and PA resins after adsorption, respectively. The considerable difference in HA adsorption between the PS and PA resins was due to the difference in molecule shape for interaction with different resin structures, which can essentially be explained by the hydrophobicity and various interactions of the PS resin. A given amount of HA occupies more positively charged sites and hydrophobic sites on the PS resin than were occupied by the same amount of HA on the PA resin. Increased pH resulted in an increase of HA adsorption onto the PA resin but a decrease in adsorption onto PS resin, as the non-electrostatic adsorption led to electrostatic repulsion between the HA attached to the resin and the HA dissolved in solution. These results suggest higher rates of adsorption and higher regeneration efficiency for interaction of HA with more hydrophilic anion exchange materials. Copyright © 2014 Elsevier Inc.

    2016-01-01

    Human skin apart from functioning as a physical barricade to stop the entry of pathogens, also hosts innumerable commensal organisms. The skin cells and the immune system constantly interact with microbes, to maintain cutaneous homeostasis, despite the challenges offered by various environmental factors. A major environmental factor affecting the skin is ultraviolet radiation (UV-R) from sunlight. UV-R is well known to modulate the immune system, which can be both beneficial and deleterious. By targeting the cells and molecules within skin, UV-R can trigger the production and release of antimicrobial peptides, affect the innate immune system and ultimately suppress the adaptive cellular immune response. This can contribute to skin carcinogenesis and the promotion of infectious agents such as herpes simplex virus and possibly others. On the other hand, a UV-established immunosuppressive environment may protect against the induction of immunologically mediated skin diseases including some of photodermatoses such as polymorphic light eruption. In this article, we share our perspective about the possibility that UV-induced immune suppression may alter the landscape of the skin’s microbiome and its components. Alternatively, or in concert with this, direct UV-induced DNA and membrane damage to the microbiome may result in pathogen associated molecular patterns (PAMPs) that interfere with UV-induced immune suppression.

    Recent genetic evidence suggests that the most important environmental influences on normal and pathologic development are those that are not shared by siblings in the same family. We sought to determine the relationship between differences in parenting styles and depressive symptoms and antisocial behavior in adolescence, and to compare the influence of these nonshared experiences with genetic influences. We studied 708 families with at least two same-sexed adolescent siblings who were monozygotic twins (93 families), dizygotic twins (99 families), ordinary siblings (95 families), full siblings in step families (181 families), half siblings in step families (110 families), and genetically unrelated siblings in step families (130 families). Data on parenting style were collected by questionnaire and by video recording of interaction between parents and children. Almost 60% of variance in adolescent antisocial behavior and 37% of variance in depressive symptoms could be accounted for by conflictual and negative parental behavior directed specifically at the adolescent. In contrast, when a parent directed harsh, aggressive, explosive, and inconsistent parenting toward the sibling, we found less psychopathologic outcome in the adolescent. Parenting behavior directed specifically at each child in the family is a major correlate of symptoms in adolescents. Furthermore, harsh parental behavior directed at a sibling may have protective effects for adolescents, a phenomenon we call the "siblin barricade."

    Full Text Available De 1870 à 1882 en France, la foule se montre un acteur essentiel dans la construction de la Troisième République. Non plus la foule qui prend la Bastille ou celle des barricades, mais la foule qui ovationne les grands leaders républicains qui ne peuvent faire sans elle. Si l’on veut bien considérer les discours « fondateurs » de Léon Gambetta, non pas seulement dans leur dimension textuelle, mais également dans leur profonde théâtralité, il convient d’analyser les grands rassemblements comme la naissance d’une modernité politique. La mémoire des foules révolutionnaires hante les esprits. Tout à la fois source vive d’inspiration pour le tribun ou d’inquiétude pour les conservateurs, les foules républicaines sont l’objet de toutes les attentions. Dans ce moment clef de l’histoire de France, le projet républicain entend les instruire, transformer en quelque sorte l’énergie issue de la foule « aveugle » en celle d’un peuple éclairé. La philosophie politique permet à l’historien d’analyser autrement ce moment fondateur. Les éclairages de Jürgen Habermas, Claude Lefort et Paul Ricoeur amènent à dépasser l’analyse classique d’une idée républicaine, pour évoquer la construction d’une société démocratique.From 1870 to 1882 in France, the crowd becomes a central actor in the construction of the Third Republic. The image of the crowd assaulting the Bastille or controlling the barricades is replaced by a crowd cheering the great republican leaders who rely on its support. A sound assessment of Léon Gambetta’s “founding” speeches needs to consider not only their textual content but also their theatrical dimension in order to analyse these events as forerunners of modern politics. As the memory of the revolutionary crowds is persisting in the first years of the Third Republic, the republican crowds catch the attention of actors from all sides of the political spectrum.

    Core hole DC-4 was completed at a depth of 3998 feet in December, 1978 by Boyles Brothers Drilling Company, Spokane, Washington, under subcontract to Fenix and Scission, Inc. The hole was cored for the US Department of Energy and the Rockwell Hanford Operations' Basalt Waste Isolation Program. Fenix and Sicsson, Inc. furnished the engineering, daily supervision of the cable tool and core drilling activities, and geological core logging for DC-4. Core hole DC-4 is located on the Hanford Site about 3 miles east of the Yakima Barricade and approximately 103 feet southwest of rotary hole DC-5, which was completed to 3990 feet in February, 1978. Hanford Site coordinates reported for hole DC-4 are north 49,385.62 feet and west 85,207.63 feet, and Washington State coordinates are north 454,468.73 feet and east 2,209,990.87 feet. No elevation survey is available for hole DC-4, but it is approximately 745 feet above mean sea level based upon the survey of hole DC-5, which has a reported elevation of 745.16 feet on the top of the 3-inch flange. The purpose of core hole DC-4 was to core drill vertically through the basalt and interbed units for stratigraphic depth determination and core collection, and to provide a borehole for hydrologic testing, cross-hole seismic shear, and pressure wave velocity studies with rotary hole DC-5. Hole DC-4 was drilled through the overburden into basalt bedrock by cable tool methods (0-623 feet) and continuously cored through the final interval (623 to 3998 feet).Core recovery was 95.8 percent of the total footage cored

    The experiences gained from several Integrated Gasification Combined Cycle (IGCC) demonstration plants operating in the US and Europe facilitate commercial success of this advanced coal-based power generation technology. However, commercialization of coal-based IGCC technology in the West, particularly in the US, is restricted due to the low price of natural gas. On the contrary, in China--the largest coal producer and consumer in the world--a lack of natural gas supply, strong demand for air pollution control and relatively low costs of manufacturing and construction provide tremendous opportunities for IGCC applications. The first Chinese IGCC demonstration project was initiated in 1994, and other potential IGCC projects are in planning. IGCC applications in re-powering, fuel switching and multi-generation also show a great market potential in China. However, questions for IGCC development in China remain; where are realistic opportunities for IGCC projects and how can these opportunities be converted into commercial success? The answers to these questions should focus on the Chinese market needs and emphasize economic benefits, not just clean, or power. High price of imported equipment, high financing costs, and the technical risk of first-of-a-kind installation barricade IGCC development in China. This paper presents preliminary technical and economic assessments for four typical IGCC applications in the Chinese marketplace: central power station, fuel switching, re-powering, and multi-generation. The major factors affecting project economics--such as plant cost, financing, prices of fuel and electricity and operating capacity factor--are analyzed. The results indicate that well-proven technology for versatile applications, preferred financing, reduction of the plant cost, environmental superiority and appropriate project structure are the key for commercial success of IGCC in China

    Exploration and extraction of mineral and petroleum resources in the arctic tundra and subarctic taiga regions of the world has potential impacts on the environment, wildlife, and human health and safety. Transportation, especially over low wet-tundra in summer, causes long-term changes in vegetation by reducing insulation to the underlying permafrost. Gravel laid directly on the tundra mat, makes the most suitable permanent road-bed. However this causes problems such as spreading of dust, impoundment of water, behavioral barricading of animals, alteration of river channels, and siltation of streams. Anadromous fishes are a major food alteration of stream channels or siltation of rivers can affect their movement and reproduction. Oil-spills in aquatic systems are harder to control and clean up than terrestrial ones, and recovery of ponds takes several years. The oil-rich outer-continental shelves in the Beaufort, Chukchi, and Bering Seas, now under exploration for oil, are especially sensitive. They contain unique populations of marine mammals and birds. Human habitation of the Arctic requires transport of food, fuel, and construction materials, and disposal of refuse and wastes which, due to the permafrost-underlain vegetative mat, is difficult. Heating by fossil fuels results in ice-fogs in winter and accumulation of atmospheric pollutants at ground-level during thermal inversions at all seasons. Perhaps the greatest impact is the increased intervention of the human population. Where native people were previously only sparsely settled or nomadic in the tundra, and on coasts where they congregated, now the economic need for resources has resulted in increased pressure overall which will result in fewer habitats for wildlife, destruction of wilderness, and increased access to humans for further exploration and recreation.

    The aim of the current study is to outline the state of affairs related to pollutants and slaughtering techniques of syngas that result both from waste thermal treatment by gasification. The study starts by a review permitting to classify the gasification techniques applied to waste thermal treatment. This review leads to distinguish between auto-thermal and allo-thermal equipments. Furthermore, are described, in this first part, the general principles and parameters of functioning and adjustment of the factors characterizing the thermal treatment in reducing atmosphere. It is also about the composition of the syngas products according to the different driving behaviours of gasifiers. Finally, we state succinctly, on one hand, the possible promotion procedures in the frame of syngas development and, on the other hand, the thresholds that we ought to reach in order to make this promotion achievable. The second part of the study deals with the characteristics of the pollutants located in the syngas. This description took the shape of a detailed index card where pollutants are classified into minority components (including those of pollutants, those of gaseous and those of particulates) according to their concentrations, to their driving behaviours and to their thermochemical conditions of formation (temperature, pressure, response-type agents, atmosphere...). In the last part, we discuss the current and the considered types of slaughtering devices in reducing atmosphere in relation with their performance in slaughtering and regarding the departure point of syngas promotion ways. Finally, are exposed the key postures and the barricades within those technologies. Hereupon, research axes are proposed. (authors)

    Full Text Available The present article is part of a dense literature – result of a perennial debate – that has polarized societies for a long time and has evident reverberations in the present. It deals with “the right to death”, trying to offer some answers referring to its existence in fact and the way in which it is perceived by different states and diverse entities with juridical nature. In the first part of the paper, it is insisted upon the right to life, so that subsequently, to speak in detail about a “right to death” and the moral and juridical implications of using such phrases. There are analyzed different states of the world found on one part or the other of the barricade in what concerns the legality of euthanasia and assisted suicide – considered the two hypostasis of the right in question. It is offered, as well, an analysis of the Convention for the Protection of Human Rights and Fundamental Freedoms, mentioning that, paradoxically, while it cannot be modified so that it allows the appearance of some new rights, it can tacitly accept the creation by some states that have adhered to it of some rights antagonistic with those presented in its text. The conclusion, is that not any liberalization movement of a social action – quantified through the request of a right – has as a direct result a progress of the respective society, especially when the action creates something diametrically opposed to some fundamental functioning norms, such as, by excellence, the granting of the protection of life of all individuals.

    Full Text Available For decades, Lebanon was war-torn by civil strife, and occupation and invasion by neighboring countries. In time, these wars have escalated in intensity from sniping, barricading streets and random shelling of residential quarters to the use of rockets, aerial bombing, and heavy artillery. Adverse mental health effects are noted in times of war with post traumatic stress disorder (PTSD as a main outcome. The aim of this study was to carry out a systematic review of published studies documenting the prevalence of PTSD in the adolescent population of Lebanon, to investigate the increase in these rates with the escalation of war intensity, and to examine PTSD determinants. A search strategy was developed for online databases (PubMed and Google Scholar between inception to the first week of January 2013. Search terms used were PTSD, adolescents and Lebanon. Eleven studies reporting PTSD in adolescents met the inclusion criteria for a total number of 5965 adolescents. Prevalence rates of PTSD ranged from 8.5% to 14.7% for the civil war, 3.7% for adolescents with sensory disabilities, 21.6% for the Grapes of Wrath War, and 15.4% to 35.0% for the 2006 July War. Some increase in PTSD rates in time is noted. Type of trauma such as bereavement, injury, house destruction, and economic problems, low self efficacy and scholastic impairment were related to PTSD. These findings may help in the development of public health policies for PTSD prevention and treatment for the protection of adolescents from war atrocities and their consequences.

  20. Remembrances of Empires Past

    Full Text Available This paper argues that the colonial legacy is ever present in contemporary Europe. For a generation, most Europeans largely tried, publicly, to forget the colonial past, or remembered it only through the rose-coloured lenses of nostalgia; now the pendulum has swung to memory of that past – even perhaps, in the views of some, to a surfeit of memory, where each group agitates for its own version of history, its own recognition in laws and ceremonies, its own commemoration in museums and monuments, the valorization or repatriation of its own art and artefacts. Word such as ‘invasion,’ ‘racism’ and ‘genocide’ are emotional terms that provoke emotional reactions. Whether leaders should apologize for wrongs of the past – and which wrongs – remains a highly sensitive issue. The ‘return of the colonial’ thus has to do with ethics and politics as well as with history, and can link to statements of apology or recognition, legislation about certain views of history, monetary compensation, repatriation of objects, and—perhaps most importantly—redefinition of national identity and policy. The colonial flags may have been lowered, but many barricades seem to have been raised. Private memories—of loss of land, of unacknowledged service, of political, economic, social and cultural disenfranchisement, but also on the other side of defeat, national castigation and self-flagellation—have been increasingly public. Monuments and museums act not only as sites of history but as venues for political agitation and forums for academic debate – differences of opinion that have spread to the streets. Empire has a long after-life.

    Magnesium (Mg) alloys have been introduced as new generation of biodegradable orthopedic materials in recent years since it has been proved that Mg is one of the main minerals required for osseous tissue revival. The main goal of the present study was to establish a desired harmony between the necessities of orthopedic patient body to Mg{sup 2+} ions and degradation rate of the Mg based implants as a new class of biodegradable/bioresorbable materials. This prospect was followed by providing a sol–gel derived nanostructured hydroxyapatite (n-HAp) coating on AZ91 alloy using dip coating technique. Phase structural analysis, morphology study, microstructure characterization, and functional group identification were performed using X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. The prepared samples were immersed in simulated body fluid in order to study the formation of apatite-like precipitations, barricade properties of the n-HAp coating, and to estimate the dosage of released Mg{sup 2+} ions within a specified and limited time of implantation. Electrochemical polarization tests were carried out to evaluate and compare the corrosion behavior of the n-HAp coated and uncoated samples. The changes of the in vitro pH values were also evaluated. Results posed the noticeable capability of n-HAp coating on stabilizing alkalization behavior and improving the corrosion resistance of AZ91 alloy. It was concluded that n-HAp coated AZ91 alloy could be a good candidate as a type of biodegradable implant material for biomedical applications. - Highlights: • Nanostructured hydroxyapatite coatings were applied on Mg based alloy. • The whole corrosion process of Mg based alloy was controlled in body fluid. • This coating was able to act as a barrier against further release of Mg{sup 2+} ions. • The coating improved the stabilization of Mg alkalization behavior.

    Magnesium is one of the most critical elements in hard tissues regeneration and therefore causes speeding up the restoration of harmed bones, while high deterioration rate of magnesium in body fluid restricts it to be used as biodegradable implants. Alloying magnesium with some relatively nobler metals such as aluminium, zinc, rare earth elements, magnesium-bioceramics composites, and surface modification techniques are some of the routes to control magnesium corrosion rate. In this study AZ91 magnesium alloy had been coated by nanostructured hydroxyapatite via sol-gel dip coating and electrophoretical methods to survey the final barricade properties of the obtained coatings. In order to perform electrophoretic coating, powders were prepared by sol-gel method, and then the powders deposited on substrates utilizing direct current electricity. Zeta potentials of the electrophoresis suspensions were measured to determine a best mode for good quality coatings. Transmission Electron Microscopy (TEM), and Scanning Electron Microscopy (SEM) were used to confirm nanoscale dimension, and the uniformity of the nanostructured hydroxyapatite coating, respectively. Fourier Transform-Infrared and X-ray diffraction analysis were utilized for functional group and phase structure evaluation of the prepared coatings, correspondingly. Electrochemical corrosion tests were performed in SBF at 37±1 (°)C which revealed considerable increase in corrosion protection resistivity and corrosion current density for electrophoretic coated specimens versus sol-gel coated specimens. Results showed that both sol-gel and electrophoretical techniques seem to be suitable to coat magnesium alloys for biomedical applications but electrophoretic coating technique is a better choice due to the more homogeneity and more crystalline structure of the coating.

  4. Organising women for Panchayati Raj.

    The recently passed 73rd Constitution Amendment Act in India focused on political structures and processes of rural India and vulnerable populations. Participation of women in Panchayati Raj Institutions was questioned in terms of the substance and effectiveness of representation. Rural women were particularly vulnerable as a group because of strong traditional values maintained in rural areas, patriarchal families, lack of women's education and access to information, poor exposure to the "outside" world, and lack of power. Local committees insufficiently represented women. Women were rarely heads of Panchayats and needed the lower positions to advance within the system. State acts have been passed to assure women's representation in Andhra Pradesh. The National Perspective Plan of 1988 provided for over 33% of seats for women and minorities as members and chairpersons of Panches and Sarpanches, based on proportional representation in the total population. Greater participation of women in politics was viewed as dependent not just on fulfilling the law but on assuring principles, democratic, and meaningful administration of government. Effort were equally necessary to address attitudinal, social, and structural barricades. Women needed to know where and how to direct their concerns so that solutions were found to the problems women faced. Women members of Panchayats needed to be educated and informed about politics: their rights, the nature of Indian democracy, policies and programs for women and the underprivileged, and voting rights. Women needed financial support for running for office. Women must view themselves as representatives of all people. Women's centers and other organizations can serve as catalysts to mobilize women and help solve political dilemmas. A combination of Constitutional provisions, government policies, social action, and self awareness among rural women will eventually result in Indian women becoming part of the mainstream political power

    Since 2012 we have carried out extensive multibeam bathymetric and backscatter surveys in coastal waters of eastern Baffin Island, supplemented by sub-bottom imaging and coring. Shore-zone surveys have been undertaken in proximity to the communities of Iqaluit and Qikiqtarjuaq, following earlier work in Clyde River. These support benthic habitat mapping, geological exploration, analysis of past and present sea-level trends, and assessment of coastal hazards relating to climate change and seabed instability. Outputs include a seamless topographic-bathymetric digital elevation model (DEM) of extensive boulder-strewn tidal flats in the large tidal-range setting at Iqaluit, supporting analysis of coastal flooding, wave run-up, and sea-ice impacts on a rapidly developing urban waterfront in the context of climate change. Seabed mapping of inner Frobisher Bay seaward of Iqaluit reveals a potential local tsunami hazard in widespread submarine slope failures, the triggers, magnitudes, and ages of which are the subject of ongoing research. In fjords of the Cumberland Peninsula, this project has mapped numerous submerged delta terraces at 19 to 45 m present water depth. These attest to an early postglacial submerged shoreline, displaced by glacial-isostatic adjustment. It rises linearly over a distance of 100 km east to west, where a submerged boulder barricade on a -16 m shoreline was discovered at a proposed port site in Broughton Channel near Qikiqtarjuaq. Palaeotopographic mapping using the multibeam data revealed an enclosed estuarine environment quite different from the present-day open passage swept by tidal currents. At Clyde River, combined seabed and onshore DEMs with geohazard mapping provided foundation data for community assessment and planning under a local knowledge co-production initiative. The geohazard work identified portions of the town-site more vulnerable to both coastal flooding and potential thaw subsidence, while the shallow delta terrace suggested a

    Full Text Available BACKGROUND Rheumatoid Arthritis (RA is a chronic inflammatory disease of unknown aetiology marked by a symmetric and peripheral polyarthritis, which often results in joint damage and physical disability. Rheumatoid arthritis is not just only a disease affecting joints, but it goes well beyond the barricade of arthritis into systemic inflammatory manifestations. Various factors play an important role in the morbidity and mortality of the disease. The aim of this study was to investigate the clinical spectrum of rheumatoid arthritis with special reference to dyslipidaemia and cardiovascular manifestations. MATERIALS AND METHODS We conducted a hospital-based observational study comprising of 72 patients of rheumatoid arthritis who had been diagnosed, based on criteria laid down by 2010 ACR/EULAR classification criteria, admitted in Gauhati Medical College and Hospital, Guwahati, Assam (India and fulfilled the inclusion and exclusion criteria. Statistical analysis was performed using GraphPad InStat version 3.00 for Windows 7, GraphPad Software, San Diego, California, USA (www.graphpad.com. P value <0.05 was taken as statistically significant. RESULTS In this study, out of 72 patients, 16 patients were male and 56 patients were female, 31.94% cases were in the 5th decade of life followed by the 4th decade (30.56% with a mean age of 43.63 years. Our study found that the most common derangement of lipid parameter was being attributed to low HDL level (31% followed by a high triglyceride level (20.83%. The prevalence of dyslipidaemia was 41.67%. Atherogenic index was high in 23.6% of the cases with a mean of 4.52 of borderline range. In this study, ECG abnormalities were present in 12.5% of study subjects, abnormal echocardiography findings were present in 11.11% of patients and abnormal carotid Doppler findings were present in 18%. The most common ECG abnormality was nonspecific ST-T changes, most common echocardiographic abnormality was pericardial

    significant advances in developing methods and techniques with the ability of tuning the biomechanical properties of hydrogels, there are still challenges regarding the synthesis of hydrogels with complex mechanical profiles as well as limitations in vascularization and patterning of complex structures of natural tissues which barricade the production of sophisticated organs. Therefore, in addition to a review on advanced methods and techniques for measuring a variety of different biomechanical characteristics of hydrogels, the new techniques for enhancing the biomechanics of hydrogels are presented. It is expected that this review will profit future works for regulating the biomechanical properties of hydrogel biomaterials to satisfy the demands of a variety of different human tissues.

    Microdevices prepared in a silicon substrate have been widely used in versatile fields due to the matured silicon-based microfabrication technique and the excellent physical properties of silicon material. However, the high thermal conductivity of silicon restricts its application in most thermal microdevices, especially devices comprising different temperature zones. In this work, a parylene-filled-trench technique was optimized to realize high-quality thermal isolation in silicon-based microdevices. Parylene C, a heat transfer barricading material, was deposited on parallel high-aspect-ratio trenches, which surrounded the isolated target zones. After removing the remnant silicon beneath the trenches by deep reactive ion etching from the back side, a high-quality heat transfer barrier was obtained. By using narrow trenches, only 5 µm thick parylene was required for a complete filling, which facilitated multi-layer interconnection thereafter. The parylene filling performance inside the high-aspect-ratio trench was optimized by two approaches: multiple etch–deposition cycling and trench profile controlling. A 4 × 6 array, in which each unit was kept at a constant temperature and was well thermally isolated individually, was achieved on a silicon substrate by using the present parylene-filled-trench technique. The preliminary experimental results indicated that the present parylene-filled-trench structure exhibited excellent thermal isolation performance, with a very low power requirement of 0.134 mW (K mm 2 ) −1 for heating the isolated silicon unit and a high thermal isolation efficiency of 72.5% between two adjacent units. Accompanied with high-quality isolation performance, the microdevices embedded the present parylene-filled-trench structure to retain a strong mechanical connection larger than 400 kPa between two isolated zones, which is very important for a high-reliability-required micro-electro-mechanical-system (MEMS) device.

    Full Text Available “So what?” Bożena Keff, Magda Szcześniak, Tomasz Tomasik & Błażej Warkocki in a conversation with Anna Zawadzka In April 2013, the Polish Press Agency published an article in which Elżbieta Janicka proposed a new interpretations of Stones on the barricades. She claimed i.a.: ”Since we are deliberating, placed in a ho-mophobic culture, where questioning someone’s heterosexual orientation is not an observation but a de­lation, I would compare Zośka and Rudy to Achilles and Patroclus, a pair of legendary warriors. […] I think that this is one of the most beautiful texts about love knowing no limits, whereas all we know about the main characters’ relations testifies to the unheard power and depth of this feeling”. Those words caused an avalanche of reactions, starting from polemics with Janicka or libels on her to violence threats against the scholar. In this conversation, Bożena Keff, Magda Szcześniak, Tomasz Tomasik, Błażej Warkocki and Anna Zawadzka are discussing Janicka’s proposition (developed in her book Festung Warschau, published prior to the quoted text to interpret Stones on the barricades as a text also on a romantic relationship between two men. They analyse social and political causes of the “scandal”, induced by the Polish mainstream media together with a part of the Polish academic milieu. This conversation took place in May 2013.   „No i co z tego”.

    modo conciso y resumido, pero recogida luego en su versión definitiva en el capítulo 6 de su libro Topographie des Fremden, volumen primero de los cuatro de que se compone su magna obra Studien zur Phanomenologie des Fremden, publicada por la editorial Suhrkamp de Frankfurt del Meno en 1997. Queremos agradecer al autor y a la editorial su cortesía al permitir que publiquemos la traducción castellana de ese ensayo. "Thinking Europe at its limits", as proposed in 1992 by a group of philosophers from the University of Strasbourg -Denis Guénoun, Philippe Lacoue-Labarthe, Jean-Luc Nancy, Daniel Payot-, means considering what the "geo-philosophy of Europe" is as an essential question that encompasses all truthful reflection surrounding the idea of Europe. The debate, to which a diverse group of colleagues and friends from different nations were invited, advanced the very possibility of an identification of Europe, together with the profoundness, in other words the very violence that this possibility (or impossibility implies, as confirmed time and again since then by recent and highly topical events. The proposal was everything but futile. Indeed, as is well known and was confirmed by the group itself some months later in July 1993, what is certain is that a storm of  terrible furores broke out and atrocious upheavals were expressed,  both intra- and extra-European, that, if nothing else, urge us to consider whether the project of what deserves to be known as a "world"may or may not be confused with the exclusive exportation of what Europe has invented, produced and identified. The future appears to be in the grip of two morbid figures, two symmetrical nightmares: the myth of a homogeneous planet, like a gigantic Europe spreading everywhere; and a confined Europe, imprisoned in its imprecise and uncertain boundaries, a kind of isolating barricade or trenches enabling it to reclusively consume the illusion of its supposed welfare. This deplorable alternative incites
