Authors: Angelescu Dorin , Gheorghe Gheorghe Ion 
Published: November 2017

AbstractOutcome of the scientific concerns from the Doctoral School of Mechanical Engineering and Mechatronics at Valahia University of Târgovişte in the field of unconventional measurements using non-contact laser technique, the scientific work “Intelligent 3D video-laser system for measuring distance and avoidance of obstruct obstacles integrable into robotic platforms” is a work in progress being in the experimental phase of single-channel testing. The system is designed for robotic platforms for special interventions in high-risk work environments, with the main goal of an active, real-time 3D spatial stereo interface for the operator who manages the robotic platform remotely. 3D imaging and real-time measurements of distances provide the operator of the robotic intervention platform with the ability to perform extremely precise maneuvers. The scientific work ultimately results in an intelligent integral system that can predict the emergence of an obstacle to the robotic platform movement, thus determining the distance in real time to it. The measuring distance is between 0 m - 40 m, with an accuracy of +/−0.5 cm being synchronized with the video system with a clear visual area from 0.05 m to infinity. The 3D video laser system can simultaneously shoot movie or single images of the obstacle, storing data in 3D, photo or video digital formats, both locally in non-volatile memory or externally thru any GPSR network to the operator and / or to a control center. In later development, the measurement system will be coupled to a GPS network for auto location of position and architected with a self-defense and offensive module mounted on the mobile robotic platform. Thus, this complex project combines in a unified knowledge of Mechatronics, Integronics, Cyber-Mix Mechatronics, Artificial Intelligence and Information Technology.

Published: November 2017

Abstract
The manuscript deals with the assessment of Radio over Fiber (RoF) system including pure electrical baseband, pure radio frequency band centered around 60 GHz, and hybrid radio-optical system at the same RF band using a global simulation. In this work we focus on RoF solution to improve the low coverage of the 60 GHz channel caused by high free-space attenuation. A realistic co-simulation of the Wireless Personal Area Network (WPAN) IEEE802.15.3c-RoF was performed in a residential environment for Line-Of-Sight (LOS) and Non-Line- Of-Sight (NLOS). In this work, we demonstrated a 60 GHz radio on Multi-Mode Fiber (MMF) using Optical Carrier Suppression (OCS) modulation. The BER (Bit Error Ratio) performance of this system is measured by varying the following parameters: optical launched power, fiber length, modulation format, Channel coding and Signal to Noise Ratio. We show that the RoF at 60 GHz can reach a minimum of 300 m of MMF without optical amplifiers followed by a 5 m wireless transmission with BER less than 10-3 in the LOS and NLOS environments.

Abstract

Introduction: The aim of study was to estimate the prevalence and intensity of intestinal parasite infections in pigs in Poland and evaluate the influence of factors related to the production system on the infection intensity.

Material and Methods: A total of 70 pig farms of all Polish provinces, differing in the herd size and production system, were selected for the study. Fresh faecal samples were collected from all age groups: suckling piglets, weaners, fatteners, and lactating sows. Moreover, data were obtained regarding the size of the herd, the use of paddock and all-in/all-out system, the presence of diarrhoea, and the type of flooring.

Results: Parasite eggs or oocysts were detected in 57 of the 70 examined pig farms. Oesphagostomum spp. eggs were found in the largest number of farms (68.6%). Moreover, coccidia (42.9%), Ascaris suum (28.6%), Trichuris suis (21.4%), and Strongyloides spp. (11.4%) were detected. The highest prevalence of coccidia and Strongyloides spp. was found in suckling piglets, A. suum and T. suis in fatteners, and Oesphagostomum spp. in sows. Higher prevalence of parasites was detected in small farms than in medium and large farms, except the prevalence of coccidia, which was the highest in medium farms. Simultaneous infection with several parasites was more often detected than with one parasite. Odds ratio of parasites occurrence was higher in farms with paddock and litter floor and in farms which do not use all-in/all-out system.

Conclusion: Relatively high prevalence of intestinal parasites was found in pigs in Poland. Moreover, specific distribution of parasites in different age groups and farms of different size was observed. Influence of breeding factors on parasite prevalence was identified.

Abstract
Diamond-like carbon (DLC) thin films were prepared by hydrothermal electrochemical method in one-step process. The structural characterization of these films was carried out by scanning electron microscopy (SEM), Raman spectroscopy, and infrared reflectance spectroscopy (IR). It was found that there was an increased sp2 carbon content but decreased sp3 carbon and hydrogen contents with an increase in current density. The flexibility and internal stresses of the DLC films were affected by hydrogen, sp3 amorphous carbon and ordered crystalline sp2 carbon contents. The highly flexible DLC films with high sp3 carbon and hydrogen contents were prepared at a current density of 0.001 mA/cm2.
Photojournalism in Central Europe

Published: November 2017

Abstract
The adoption of digital technologies, along with current economic realities, has affected the entire process of visual news production. It has also influenced the traditional concept of photojournalism. As a result, news photographers face multiple new challenges. Although visual news material is becoming ever more important, news organizations have cut back on employment, leaving those few who remain employed with additional workload and responsibilities. Based on interviews with photojournalists and photo editors, this article examines the current state of photojournalism and editorial processes in three Central European countries – the Czech Republic, Poland and Slovakia. Findings indicate that photojournalists and photo editors face ongoing developments in the photographic medium that significantly affect their working practices and routines. At the same time, they must deal with increasing workload, new responsibilities, competition and the challenges of maintaining quality in the digital age.

Abstract
The objective of this study was to evaluate ultra high performance concrete (UHPC) as a precast product material containing portland type II cement, quartz powder, silica fume, silica sand, steel fiber, superplasticizer, water, and a specific amount of incinerator fly ash (IFA). The UHPC mixes containing different volumes of IFA were evaluated to find the optimum quality of precast production, while 2.5 % of steel fiber by volume was blended at every mix. The results indicate that the properties of UHPC exhibit high strength, ductility, and bonding stress. The compressive strength of UHPC decreases greatly as IFA for part replacement of cement or quartz powder increases. However, the flexural strength of UHPC decreases a little as IFA for part replacement of quartz powder increases. The results demonstrate that the UHPC products with 10 % or 15 % IFA were able to withstand a 98-kN proof load to the cover and frame without cracks or permanent deformation. It has to be noted that heavy metals that originated in the IFA are confined in the UHPC matrix and yield rather low leachability results.

Abstract
The fatigue failure of automobile structures has drawn much attention recently in reliability and endurance design. Therefore, in order to predict the fatigue life accurately, complex variable-amplitude loads must be compiled into the appropriate load spectrum. The rain-flow counting method is adopted to extract the load cycles from the random loads. A statistical method based on the mixture distribution model is proposed to analyze the multimodality of load cycles. Meanwhile, the collected random loads are extrapolated to the full life of vehicles based on the Peaks-Over-Threshold model. Finally, the one- and two-dimensional load spectrums are compiled according to the load cycles and joint probability density.

The impact of climate change on soil organic C (SOC) stocks in no‐till (NT) and conventionally tilled (CT) agricultural systems is poorly understood. The objective of this study was to simulate the impact of projected climate change on SOC to 50‐cm soil depth for grain cropping systems in the southern Mid‐Atlantic region of the United States. We used SOC and other data from the long‐term Farming Systems Project in Beltsville, MD, and CQESTR, a process‐based soil C model, to predict the impact of cropping systems and climate (air temperature and precipitation) on SOC for a 40‐yr period (2012–2052). Since future crop yields are uncertain, we simulated five scenarios with differing yield levels (crop yields from 1996–2014, and at 10 or 30% greater or lesser than these yields). Without change in climate or crop yields (baseline conditions) CQESTR predicted an increase in SOC of 0.014 and 0.021 Mg ha−1yr−1in CT and NT, respectively. Predicted climate change alone resulted in an SOC increase of only 0.002 Mg ha−1yr−1in NT and a decrease of 0.017 Mg ha−1yr−1in CT. Crop yield declines of 10 and 30% led to SOC decreases between 2 and 8% compared with 2012 levels. Increasing crop yield by 10 and 30% was sufficient to raise SOC 2 and 7%, respectively, above the climate‐only scenario under both CT and NT between 2012 and 2052. Results indicate that under these simulated conditions, the negative impact of climate change on SOC levels could be mitigated by crop yield increases.Core IdeasSoil organic C was greater in a no‐till than a conventional tillage system.CQESTR model‐simulated soil organic C increased under both systems.CQESTR‐simulated soil organic C decreased under climate change.Simulated soil organic C decreased under climate change when yields were reduced.Simulated soil organic C increased under climate change when yields were increased.
Agencification in Asia: Lessons from Thailand, Hong Kong, and Pakistan
Authors: Pratama Arif Budy 
Published: November 2017

This paper discusses the agencification phenomena as one of New Public Management (NPM)-based administrative reform initiatives. Thailand, Hong Kong, and Pakistan were chosen because of their similarity on administrative legacy and availability of data. The study uses a review of literature research method, while comparative approach was employed to analyze experiences of agencification in the three selected cases. Research result showed that the three countries implemented agencification in different ways; rational agency model is not the only driver for agencification initiatives; and contextual factor that include traditions, cultures, structures, and values influence the implementation of agencification process as a public sector reform initiative. Policy implications can be drawn by reading the three countries on agencification. Thus, Indonesia, as one of NPM adopters can learn from experience gleaned from the three polities in conducting its administrative reform agenda.

The Vise of Geometry: Distorting Intersectionality at the Scene of Argument
Authors: Tomlinson Barbara 
Published: November 2017

Abstract
Intersectional thinking emerged as a provocation in contemporary feminist studies as a political and analytic concept, a sensibility or disposition, a heuristic for thinking in supple and strategic ways about social categories and relations of power in terms of “both/and” rather than “either/or” (see Crenshaw 1989, 1991; Collins 1991). But in contemporary feminist critiques of intersectionality, it is frequently misrepresented, portrayed as fixed when it is fluid and flexible, and accused of creating the very categories and social relations it exposes and challenges. Few theories are as consistently misrepresented. The compelling conception of intersectionality proposed by Black feminists and other feminist scholars of color has a long—often ignored—history in scholarship and activism. In the 1970s and 1980s it represented a dramatic challenge to a white feminism that framed gender as the primary axis of oppression and white women as the primary representatives of feminism. Rather than welcoming this critique as a necessary tool for crafting a more capacious feminist practice, many white feminists perceived the emergence of intersectionality as a loss of power and prestige for themselves. This shock—seeming to lose control of a previously undifferentiated yet implicitly white feminism—continued to echo in the 1990s as white feminist scholars engaged in a series of interventions to counter and appropriate intersectionality. These interventions have become part of a chain of misrepresentations that continue to reverberate today through their citation, reiteration, and imitation (see Tomlinson 2013a, 2018).
In practice, intersectionality informs, guides, and shapes advanced research in substantive and generative ways. But the relentless citational attack on intersectionality has made the term itself seem like damaged goods, often disavowed. These practices attempt to both diminish the luster of intersectionality and co-opt its prestige in the service of a revanchist white feminism. Such efforts are not the product of individual choices and errors but rather a shared social discourse pervading feminist scholarship, a discourse that is caught in continual reinscriptions of these arguments rather than reflecting on, reformulating, and moving beyond them. As a result, the valuable feminist tool of intersectional inquiry experiences a kind of stasis that needs to be overcome by transforming feminist tools of reading and writing. Critical feminist studies cannot allow arguments about multidimensionality and race to congeal around strategies that reinforce white women's symbolic domination of the field. In this article I examine two attempts to distort intersectionality through the trope of the vise of geometry.
Despite Your Tiger Mother, or Your Other Racial Half Will Not Save You from What the World Thinks of Your Blackness
Authors: Taiwo Wendy Thompson 
Published: November 2017

Abstract
In this personal essay, the author analyzes what it means to be black and Asian American in a nation where racial capital determines social value and non-black immigrants are encouraged to uphold and abide by anti-black systems, policies, and practices. Narrating her experience as a black Chinese American woman, the author reflects on having received anti-black messages throughout her childhood and how her need for healing has paralleled her work which challenges existing racial logic that casts Asian Americans as a model minority in competition and conflict with black people who are cast as social failures. Recognizing this racial/racist logic as one that allows white America to absolve itself from its central role in maintaining structural oppression, the author argues for the continued calling out of anti-blackness in all spaces—public and intimate, white and non-white—while carving out a path to empowerment, creativity, and freedom for herself and her daughter.
Sex Wars and the Contemporary French Moral Panic: The Productivity and Pitfalls of Feminist Conflicts
Authors: Möser Cornelia 
Published: November 2017

Abstract
Over the past few years, right-wing political groups in France have made sexuality a focus of their concerns. Since the debate about political lesbianism in 1980, feminist research on sexuality in France has been markedly limited to research on abortion, contraception, and sexual violence. In this article, I look back at the US feminist “sex wars” as a crucial turning point in feminist thought on sexuality and examine different aspects feminists address when speaking about sexuality. I argue that the multiplicity of levels of thinking sex brought up by US feminists opposes a structural- and an individual-based perspective. These multiple levels crosscut on the topics of sexual practices, identities, and morals, the very themes of the sex wars. Together they compose the technology of power (Foucault 1976) that has been constructed under the name of sexuality in the nineteenth century. The contributions of the US feminist debate on sexuality help to broaden an understanding of sexuality in today's politics in France. But in taking a closer look at the US feminist sex wars, it appears that they actually coincide with the US construction of French feminism and French theory. The trajectories of Monique Wittig's and Michel Foucault's works provide examples of the productivity of translations. They also stand for different feminist strategies of thinking sex that after a closer examination do not seem so radically opposed any more. Through this analysis the deconstruction of sexuality as an entity is suggested in re-embracing the critical questions set by the authors of the sex wars.

<p class="Default"><span>Este artigo investiga a participação dos sujeitos em ativismo social como fator de enfrentamento e, ou, ressignificação da violência urbana. Os objetivos específicos foram conhecer a vivência da violência urbana expressa pelos entrevistados, estudar as principais formas de enfrentamento e refletir sobre possíveis relações entre as vivências de violência na saúde. Foram realizadas catorze entrevistas com membros de quatro instituições cariocas de enfrentamento da violência urbana. A violência se mistura e influencia a história de vida dos ativistas, na qual o cotidiano e as atividades diárias foram modificados pelas experiências de violência. A maior parte dos entrevistados afirmou ter tido a saúde física e mental alterada/prejudicada. Identificou-se o uso de estratégias individuais e coletivas de enfrentamento da violência. A lógica interna do grupo aponta que a atitude de lidar com a violência é considerada como uma forma de proteção, levando à construção de estratégias de enfrentamento e, ou, redução da violência urbana. </span></p>
