Authors: Lambey V. , Prasad A. D.
Published: November 2018

Abstract. Photogrammetric surveying with the use of Unmanned Aerial Vehicles (UAV) have gained vast popularity in short span. UAV have the potential to provide imagery at an extraordinary spatial and temporal resolution when coupled with remote sensing. Currently, UAV platforms are fastest and easiest source of data for mapping and 3D modelling. It is to be considered as a low-cost substitute to the traditional airborne photogrammetry. In the present study, UAV applications are explored in terms of 3D modelling, visualization and parameter calculations. National Institute of Technology Raipur, Raipur is chosen as study area and high resolution images are acquired from the UAV with 85% overlap. 3D model is processed through the point cloud generated for the UAV images. The results are compared with traditional methods for validation. The average accuracy obtained for elevation points and area is 97.99% and 97.75%. The study proves that UAV based surveying is an economical alternative in terms of money, time and resources, when compared to the classical aerial photogrammetry methods.

Published: November 2018

Abstract. Land Use/ Land Cover (LU/LC) is a major driving phenomenon of distributed ecosystems and its functioning. Interpretation of remote sensor data acquired from satellites requires enhancement through classification in order to attain better results. Classification of satellite products provides detailed information about the existing landscape that can also be analyzed on temporal basis. Image processing techniques acts as a platform for analysis of raw data using supervised and unsupervised classification algorithms. Classification comprises two broad ranges in which, the analyst specifies the classes by defining the training sites called supervised classification where as automatically clustering of pixels to the defined number of classes namely the unsupervised classification. This study attempts to perform the LU/LC classification for Paonta Sahib region of Himachal Pradesh which is a major industrial belt. The data obtained from Sentinel 2A, from which the stacked bands of 10 m resolution are only used. Various classification algorithms such as Minimum Distance, Maximum Likelihood, Parallelepiped and Support Vector Machine (SVM) of supervised classifiers and ISO Data, K-Means of unsupervised classifiers are applied. Using the applied classification results, accuracy assessment is estimated and compared. Of these applied methods, the classification method, maximum likelihood provides highest accuracy and is considered to be the best for LU/LC classification using Sentinel-2A data.
ON THE USE OF CITSCI AND VGI IN NATURAL HAZARD ASSESSMENT
Authors: Kocaman S. , Gokceoglu C.
Published: November 2018

Abstract. The developments in the geospatially-enabled mobile communication technologies have opened new horizons in many fields of geosciences research, especially in those where data collection, processing and interpretation are time consuming and costly. Being one of these research fields, natural hazards also require high spatiotemporal data density and distribution, which is extremely difficult to obtain and also equally essential to secure the main assumptions of these researches and thus yield to proper conclusions. These problems can be solved with the help of citizen science (CitSci) methods and the volunteer geographical information (VGI). These two terms are complementary, or intertwined, and mutually benefit from each other for achieving their goals. This paper investigates the developments in CitSci and VGI with a specific focus of natural hazard researches and gives a brief overview of the literature. The importance of their use in natural hazards, open research areas and future aspects are also analysed. Based on the previous experiences and analyses, the authors foresee that such investigations would help researchers to utilize CitSci and VGI in their studies, and thus benefit the advantages of both approaches and improve the quality of their data. On the other hand, the growing interest of citizen scientists for supporting scientific processes could be steered to the fields where most help is needed. Specifically, detection of ground deformations after earthquakes is explained here and a simple mobile app developed for landslide data collection is briefly depicted as use case.

Abstract. The accurate, detailed and up-to-date road information is highly essential geo-spatial databases for transportation, smart city and other related applications. Thus, the main objective of this research is to develop an efficient algorithm for road network extraction from airborne LiDAR data using supervised classification approach. The proposed algorithm first classifies the input data into the road and non-road features using modified maximum likelihood classification approach. Then Digital Terrain Model (DTM) mask is generated by removing non-ground features from Digital Surface Model using hierarchical morphology and road candidate image if obtained. The parking lots are removed and road network is extracted successfully.
CLASSIFICATION OF THE STRUCTURE OF CITIES THROUGH MID-RESOLUTION SATELLITE IMAGERY AND PATCH BASED NEURAL NETWORKS
Authors: Verma D. , Jana A. , Ramamritham K.
Published: November 2018

Abstract. The studies in the classification of the urban spatial structure have been essential in deriving insights into the land cover and the built typology which helped in the estimation of energy consumption patterns, urban density, compactness, and hierarchy of settlements. However, the analysis and comparison of the physical forms of the cities have been attempted in a piecemeal fashion where the requirement of datasets and the computation power for analysis has been a major hindrance. With the advancement in machine learning based techniques, large datasets such as satellite imagery can be studied with advanced computer vision methods. These solutions may help in studying the intricate nature of human habitats in large extents of geographical areas including various urban areas. This study utilizes smaller patches of medium resolution Sentinel-2B Imagery of ten different cities in India to explore the urban forms present in these cities. This study uses Stacked Convolutional Autoencoder (CAE) to reduce the dimensionality of satellite imagery patches and unsupervised clustering techniques such as t-SNE and K-means to study the characteristics of similar patches. On analyzing the clusters through visual exploration, similar patches are delineated and provided with corresponding labels representing urban forms. Individual clusters are then studied with respect to each city. The motive of the study is to gain insights into the different types of morphological patterns present within and among cities.

The whole project aims at reducing generational gaps between the students by bringing them the opportunity for knowledge co-creation through transdisciplinary projects on agricultural sector using GI technologies.
PARTICLE SWARM OPTIMIZATION BASED APPROACH TO ESTIMATE EPIPOLAR GEOMETRY FOR REMOTELY SENSED STEREO IMAGES
Authors: Mahato M. , Gedam S.
Published: November 2018

Abstract. A novel particle swarm optimization based approach for the estimation of epipolar geometry for remotely sensed images is proposed and implemented in this work. In stereo vision, epipolar geometry is described using 3 × 3 fundamental matrix and is used as a validation tool to assess the accuracy of the stereo correspondences. The validation is performed by enforcing the geometrical constraint of stereo images on the two perspective projections of a point in the scene for finding inliers. In the proposed method, the steps of particle swarm optimization such as the initialization of the position and velocity of the particles, the objective function to compute the best position found by the swarm as well as by each particle experienced so far, the updating rule of velocity for the improvement of the position of each particle, is designed and implemented to estimate the fundamental matrix. To demonstrate the effectiveness of the proposed approach, the results are obtained on a pair of remotely sensed stereo image. A comparison of the result obtained using the proposed algorithm with RANSAC algorithm is carried out. The comparison shows that, the proposed method is effective to estimate robust fundamental matrix by giving improved number of inliers than RANSAC.

Abstract. The Thomas Fire burned 114 078 ha in Santa Barbara and Ventura counties,
southern California, during December 2017–January 2018. On 9 January 2018,
high-intensity rainfall occurred over the Thomas Fire burn area in the
mountains above the communities of Montecito and Carpinteria, initiating
multiple devastating debris flows. The highest rainfall intensities occurred
with the passage of a narrow rainband along a cold front oriented north to south. Orographic enhancement associated with moist southerly flow
immediately ahead of the cold front also played a role. We provide an
explanation of the meteorological characteristics of the event and place it
in historic context.

What Was the Impact of Zionism on Displaced Jewish Refugees in Germany in the Aftermath of the Second World War?
Authors: Bruno Francesco
Published: November 2018

This paper explores the birth of the state of Israel with particular emphasis on the role of the Zionist ideology. Zionism as an ideology can be seen not only as a singular ideological view, but as a confluence of multiple ideas that trace back to the 19th century and even earlier to the diaspora of the Jewish people. The final product of the Zionist idea is the state of Israel. Great emphasis in this paper Is given to the role of Zionism after the end of World War II, which saw the mass murder of over 6 million Jewish. Zionism posed the dilemma to the Jewish people in the following terms: the creation of a state where Jewish people could have been represented as the majority with their own rules and legislation and the complete assimilation within other countries. In other words, Zionism aimed to give the Jewish people a nationalistic identity and remains a strong factor that influenced the Jewish people within the DP camps in the aftermath of the Second World conflict. The paper begins with the analysis of Zionism as an ideology from the 19th century onward and the conditions of the Jewish people in the aftermath of World War II. These two points are then analysed to demonstrate two main points. The first is the resiliency and adaptability of the Zionist ideology as the only way forward for the Jewish people and second, the status of the Jewish people as “victims” and this idea gave them the freedom to approach the creation of a new society with a general “benevolence” from the international community.
Accounting for windthrow risk in forest management planning: a Romanian tailor-made solution
Authors: Dragoi Marian , Barnoaiea Ionut
Published: November 2018

Aim of study: To better estimate the annual allowable cut reserve (AACR), taking into consideration the endemic windthrows (EW), we combined a series of existing algorithms into a coherent methodology to use the data available at district level, without any additional fieldworks.Area of study: The algorithm was tested on the EW occurred in the last 20 years in Brosteni FD (Eastern Carpathians, Romania) that covers 21,013 ha and we found that every year from an AAC of 37,000 m3 no more than 2,700 m3 shall be spared for EW that might occur next year.Material and methods: We considered three EW enabling factors (stand slenderness, location on pits and mounds, and the vicinity of canopy gap) and three contingency tables of the EW produced between 1999 and 2008, one for each 40-year age group. Then we calculated a Bayesian model for all six permutations of enabling factors, each of them being tested on the data referring to 2008-2017 periodResults: Plugging the posterior EW likelihoods into a Markov chains (MC) model, we produced a formula that enables a better estimation of the optimal AACR that could be replaced with salvage cuttings every next year. Other options of using the EW likelihoods are also presented at length, such as the type of age-class structure that requires no AACR, that is a “U” shape age structure, as well as a rough assessment of the additional demand for seedlings needed to re-plant the stands affected by EW. The relatively short period of time the input data refer to, which is ten years, equals the time window of the forest planning and this parity allows a ten-year forecast period, enough for modeling the stationary age-structure of even-aged forests.Research highlights: A new model for optimizing the annual allowable cut (AAC) in even-age forests in the context of endemic windthrows (EW) scenario has been developed and evaluated.Keywords: Bayes’ rule, forest management planning, endemic windthrows.
Optical, Photoelectrochemical and Impedance Studies on Poly 3,3’ Dibromo, 2,2’ Bithiophene: Effect of Bromine as a Substituent at C-3 Position in 2,2’ Bithiophene Molecules
Authors: Kasem Kasem K. , Sadou Houria , Jeffers Anthony W.
Published: November 2018

Thin films of poly 3, 3’ dibromo, 2,2’ biththiophene (PDBrBTh) and poly 2,2’ biththiophene (PBTh) on fluorine doped tin oxide electrode (FTO) were subjected to optical, electrochemical and impedance studies in various aqueous electrolytes. Both polymers showed electrochromic properties, where the neutral film at -1.0 V vs Ag/AgCl shows red color, and the oxidized (doped) film at positive potentials shows blue color. Optical studies indicated that PDBrBTh showed a greater optical band gap than that of PBTh. Our studies also showed that the presence of bromine as a substituent at the C-3 position of the thiophene ring causes a greater ionization potential (IP) than PBTh. PDBrBTh also shows closer values of refractive index(n), and real (εr,) and imaginary (εi) dielectric constants to that of PBTh at photon energies between 2.0eV and 3.0 eV. At lower photon energy PDBrBTh showed lower optical conductivity than Br-free PBTh. Study also indicated that PDBrBTh is much less photoactive that PBTh. Electrochemical impedance spectroscopic studies (EIS) revealed that PDBrBTh possesses less relaxation time, and less double layer capacitance (Cdl) in dark and under illumination.
Parametric Interval Estimation of the Geeta Distribution
Authors: Korir Betty C. , Kinyanjui Josphat K.
Published: November 2018

It is well known that the sample mean is the estimator of a population mean in mathematical statistics from a given population of interest as a point estimator which assume a single number that is obtained by taking a random sample of a specified size from the entire population, depending on whether the population mean and variance is known or unknown. In the interval estimation, the sample mean is accompanied with a plus or a minus margin of an error that is assumed that the estimator is contained within the range of values with certain degree of confidence. This paper investigated and obtained the interval estimators of the unknown constants of Geeta distribution model through the construction of confidence interval using; the pivotal quantity method, the shortest-length confidence interval, unbiased confidence interval estimators, Bayesian confidence interval estimators and statistical method. Geeta distribution is a new discrete random variable distribution defined over all the positive integers, with two unknown parameters. The properties and characteristics of the Geeta distribution model were discussed and reviewed that is, the existence of the mean, variance, moment generating function and that the sum of all probabilities is unity. These are common properties of any given probability density function.
An Exact Method for Power Calculation for a Three-arm Clinical Endpoint Bioequivalence Study
Authors: Yang Aotian , Sun Wanjie
Published: November 2018

A clinical endpoint bioequivalence (BE) study aims to establish BE between a generic drug (TEST) and an innovator drug (REF). A placebo (PLB) is usually included to demonstrate the sensitivity of the study. BE is established if TEST is shown to be superior to PLB, REF superior to PLB, and TEST equivalent to REF. Therefore, an overall BE test for a clinical endpoint BE study is composed of two superiority tests (TEST vs. PLB and REF vs. PLB) and one equivalence test (TEST vs. REF).

Previously, Chang et al (2014) calculated the sample size and power for an overall BE test based on one superiority test (TEST vs. PLB) and an equivalence test (TEST vs. REF) using the joint distribution of sample means and sample variances because ’it is not easy to derive the sample size based on the multivariate t-distribution’ (we call this a ZChiSquare method). In this paper, we propose an exact method to calculate the power and sample size for an overall BE test based on two superiority tests (TEST vs. PLB, REF vs. PLB) and one equivalence test (TEST vs. REF) using a multivariate non-central t distribution directly, which we call an Exact-t method. We also extended the Z-ChiSquare method to an overall BE test with two superiority tests and one equivalence test, rather than one superiority and one equivalence test as in Chang et al’s paper.

Simulation shows that our proposed Exact-t method is computationally more efficient than the Z-ChiSquare method without self-writing codes to numerically calculate the conditional expectation of a multivariate normal distribution conditional upon a truncated Chi-Square distribution. When sample size is small, the Exact-t method generates more accurate results than the Z-ChiSquare method.

The Exact-t method is recommended when calculating power and determining sample size for a three-arm clinical endpoint BE study.

Published: November 2018

In this work, a study of samples that contained cocaine camouflaged inside unidentified polymers was performed. Samples were seized at the Dorado International airport in Colombia. Cocaine was adsorbed or occluded within the matrix. The objective of this research was to extract cocaine from the matrices using soxhlet extraction method. Thereafter matrices were analyzed to determine the surface morphology before and after the extraction. Several morphological differences were exhibited between samples including both adsorbed and occluded cocaine. Moreover, changes in the surface morphology were also observed before and after cocaine extraction. The chemical elemental composition of matrices was also studied using energy dispersive spectroscopy, observing that the alkaloid was totally removed in almost all samples after the extraction process. On the other hand, Thermo gravimetric analysis also allows comparing the results obtained for the samples with patterns of pure cocaine and other polymers as CMC, PVA and HEC, finding several similarities of structural type.
EROZIJA TLA VODOM KAO SMJERNICA ODRŽIVOG GOSPODARENJA TLOM NA KRŠU JUŽNOJADRANSKE POLJOPRIVREDNE PODREGIJE HRVATSKE

Published: November 2018

Tlo krša (s vodom i zrakom) kao dio „ekološkog trojstva“ i sastavnica osjetljivih i ranjivih terestričkih ekosustava, među kojima agro- i silviekosutava u središtu su pažnje u Međunarodnom desetljeću tla 2015 ̶ 2014. Tla na vapnencu i dolomitu kao najrasprostranjenijim stijenama krša nastaju otapanjem kalcijeva i magnezijeva karbonata i nakupljanjem netopivog ostatka, koji je u te stijene uklopljen u vrijeme njihova nastanka. Sporost toga procesa oslikava podatak da tvorba sloja tla 1 cm debljine, uz uvjet da nema erozije traje 8 000-10 000 godina. Stoga je razumljivo da je zaštita toga blaga od erozije ključno pitanje opstanka tla i terestričkih ekosustava na sredozemnom kršu. U projektu izravnog mjerenja erozije feralitičnih tala Etiopijske visoravni (4 godine) i pseudogleja središnje Hrvatske (20 godina) provjerili smo pouzdanost i upotrebljivost najpoznatije prognostičke metode – Univerzalne jednadžbe erozije – USLE Wishmeiera i Smitha (1978). Rezultati su nas ohrabrili pa smo tu metodu koristili i u ovom radu, premda krš ima posebnosti koje otežavaju sve prognoze erozije. Općenito se u svijetu i EU koristi isključivo revidirana ili dopunjena (R)USLE, koja, uz sve nedostatke, kojih uostalom nije lišena niti jedna prognostička metoda, predstavlja solidnu osnovu za izradu smjernica održivog gospodarenja tlom, a revizija te metode je poželjna. Rezultati istraživanja nedvojbeno pokazuju da na području Južnojadranske poljoprivredne podregije uzgoj oraničnih usjeva – širokorednih (okopavina) i gustog sklopa dolazi u obzir samo na tlima na ravnom terenu, dakle u krškim poljima, riječnim dolinama, docima i ponikvama (vrtačama), odnosno na prirodnim ili izgrađenim terasama.

Authors: Miranda Benjamin H , Elliott Charlotte , Kearsey Christopher C , Haughton David N , Webb Mark R , Harvey Ian , Fahmy Fahmy S
Published: November 2018

Background Numerous Dupuytren’s fasciectomy techniques have been described, each associated with unique surgical challenges, complications and recurrence rates. We describe a common ground surgical approach to Dupuytren’s disease; 3-dimensional fasciectomy (3DF). 3DF aims to address the potential contributors to the high recurrence rate of Dupuytren’s disease and unite current limited fasciectomy practice that varies considerably between surgeons.

Methods We describe the 3DF principles; raising thin skin flaps (addressing dermal involvement), excising diseased palmar fascia with a 3−5 mm clearance margin (treating highly locally recurrent conditions) and excising the vertical septae of Legueu and Juvara (providing deep clearance, hence addressing all potentially involved pathological tissue). The surgical outcomes between traditional limited fasciectomy (LF) and 3DF are compared.

Results From the 786 operations included (n=585), postoperative recurrence rates were significantly lower for the 3DF group (2/145, 1.4%) than the LF group (72/641, 11.2%) (P=0.001), and the time to recurrence was significantly longer (5.0±0 years vs. 4.0±0.2 years; P<0.0001). With recurrence excluded, there were no differences between the postoperative complication rates for 3DF (5/145, 3.5%) and LF (41/641, 6.4%) (P=0.4).

Conclusions Our results suggest that 3DF leads to lower recurrence rates and a longer disease-free period for patients, without increasing complications. 3DF provides a safe, efficacious, common ground surgical approach in the treatment of Dupuytren’s flexion deformity.
Adult-onset kaposiform hemangioendothelioma with neurofibromatosis type 1: A case report and literature review
Authors: Kim Dong Hwi , Lee Ji Sung , Shin Jong Weon , Kim Jean A , Jun Young Joon
Published: November 2018

Kaposiform hemangioendothelioma (KHE) is a very rare, locally aggressive vascular neoplasm. It occurs mostly in children and is rarely observed in adults. It typically originates on the skin, later affecting the deep soft tissue of the extremities, head or neck, and retroperitoneum by infiltrative growth. It is locally aggressive, does not regress spontaneously, and tends to metastasize locally as well as to the regional lymph nodes. In this article, we report a case of adult-onset KHE with neurofibromatosis type 1. The patient presented to our department with a 2-month history of a painful ulceration in her left popliteal area. Since KHE had not previously been reported in patients with neurofibromatosis, the diagnosis was difficult due to the similarity of the skin manifestation to neurofibromatosis-associated lesions. We share our experience of diagnosing and treating this rare case of adult-onset KHE.

Published: November 2018

Background Infantile hemangioma (IH) is a common vascular tumor in pediatric patients, and is commonly treated with propranolol. We describe our experiences with dosage, response to treatment, and side effects in 23 IH patients treated with propranolol.

Methods For this nonrandomized comparative cohort study, the authors enrolled 23 patients treated with propranolol. Photographs were taken before propranolol administration and at 3, 6, 9, and 12 months after treatment. Treatment responses were objectively analyzed with a computer program.

Results There were three male and 20 female patients. Common tumor locations were the head and neck (13 cases, 56.5%), trunk (four cases, 17.4%), extremities (three cases, 13.0%), and combined locations (three cases, 13.0%). The response to propranolol was significantly lower in patients with two or more lesions than in patients with a single lesion in terms of both color fading (P<0.001) and size reduction (P<0.001). In male patients (42.2±3.9), the change in a-values, indicating coloration, was higher than in female patients (19.8 ±13.8)(P<0.001). In patients who started treatment before 6 months after birth, the size reduction was greater than in their counterparts (62.3%; range, 3.0%–93.0% vs. 15.8%; range, 1.0%–79.0%; P<0.001).

Conclusions Propranolol is an efficacious treatment with a good safety profile. In patients with a single lesion, the response to treatment was better in terms of color fading and size reduction. Furthermore, male patients responded better to propranolol treatment in terms of color fading than female patients, and starting treatment before 6 months after birth was more advantageous for size reduction.
Lower facial contouring surgery using a novel method: M-genioplasty
Authors: Lee June Bok , Han Jin Woo , Park Jun Hyung , Min Kyung Hee
Published: November 2018

Background Mandibular contouring surgery to produce a more slender and small face has become popular, especially in East Asia. Narrowing genioplasty should be simultaneously performed with mandibular angle resection to achieve satisfactory results. In Korea, T-genioplasty has been frequently performed for chin narrowing. The authors developed a new, safe, and reliable method, termed M-genioplasty, that can provide a more slender and attractive lower face.

Methods From June 2013 to December 2017, 36 patients underwent M-genioplasty with mandibular angle resection for lower facial contouring. Horizontal and vertical osteotomies were performed obliquely. The resected bone segments were wedge-shaped. The remaining two bone segments were rotated and approximated centrally. The lateral mandible bony stepoff was trimmed off for mandibular angle resection.

Results In all patients, the facial contour sufficiently improved, and most patients were satisfied with the outcome. No severe complications took place during postoperative follow-up.

Conclusions M-genioplasty can provide more mandibular angle resection and can create a more acute chin angle without bone resorption than other methods, including T-genioplasty. M-genioplasty with mandibular angle resection is a safer, more accurate, and more reliable method for lower facial contouring.
Wound healing effects of paste type acellular dermal matrix subcutaneous injection
Authors: Lee Jin Ho , Kim Jae-Won , Lee Jun-Ho , Chung Kyu Jin , Kim Tae Gon , Kim Yong-Ha , Kim Keuk-Jun
Published: November 2018

Background Acellular dermal matrix (ADM) helps wound healing by stimulating angiogenesis, acting as a chemoattractant for endothelial cells, providing growth factors, and permitting a substrate for fibroblasts to attach. The current standard for using paste-type ADM (CG Paste) in wound healing is direct application over the wounds. The major concerns regarding this method are unpredictable separation from the wounds and absorption into negative-pressure wound therapy devices. This study aimed to investigate the effects of subcutaneous injection of paste-type ADM on wound healing in rats.

Methods Full-thickness skin defects were created on the dorsal skin of rats. Eighteen rats were randomly divided into three groups and treated using different wound coverage methods: group A, with a saline dressing; group B, standard application of CG Paste; and group C, injection of CG Paste. On postoperative days 3, 5, 7, 10, and 14, the wound areas were analyzed morphologically. Histological and immunohistochemical tissue analyses were performed on postoperative days 3 and 7.

Results Groups B and C had significantly less raw surface than group A on postoperative days 10 and 14. Collagen fiber deposition and microvessel density were significantly higher in group C than in groups A and B on postoperative days 3 and 7.

Conclusions This study showed comparable effectiveness between subcutaneous injection and the conventional dressing method of paste-type ADM. Moreover, the injection of CG Paste led to improved wound healing quality through the accumulation of collagen fibers and an increase in microvessel density.
Acalyptris amazonensis sp. nov.: documentation of another leaf-mining species supplementing the unique but disputable A. latipennata group (Lepidoptera: Nepticulidae)
Authors: Stonis Jonas R. , Diškus Arūnas
Published: November 2018

We describe one new species (Acalyptris amazonensis sp. nov.) from the Amazonian rainforest of Ecuador and provide the first photographic documentation of two other related species also occurring in Ecuador (A. onorei Puplesis & Diškus and A. ecuadoriana Puplesis & Diškus). We briefly discuss diagnostic characters of the A. latipennata species group, which has an outstanding but disputable position within the genus Acalyptris Meyrick.

Published: November 2018

In the Baltic countries, the golden jackal (Canis aureus) was first recorded in Estonia on 28 February 2013 and three specimens of golden jackal were hunted in Latvia in 2014. The first golden jackal in Lithuania was hunted on 7 February 2015. The species of the golden jackal was identified using morphological and mitochondrial DNA control region (CR1) analysis. In Lithuania, hunting of these animals is permitted throughout the year. Few studies in the past revealed the potential role of the golden jackal as a carrier of intestinal helminths, parasites, and zoonotic diseases. In this study, the presence of tick-borne pathogens and other parasites in golden jackal specimen were investigated. No pathogens (Anaplasma phagocytophilum, Babesia sp., Bartonella sp.) were found in the spleen of the golden jackal. However, the flukes Apophallus donicus, nematodes Uncinaria stenocephala, and unidentified individuals of class Cestoda were detected. Helminths A. donicus and U. stenocephala are not new species for Lithuania and neighbouring territories.

Reliable testing of effects of various natural and synthetic substances on cells is critical in searching for effective inhibitory or stimulating agents. Such work is essential in the discovery of anticancer drugs and testing toxicity of newly synthesized compounds. We use the TSITOMIR (“World of Cells”) computer video complex developed in cooperation with the Planar Corporation (Minsk). This complex is intended for time-lapse video microscopy of living cells (mouse and human fibroblasts, cells from human hair follicle and urine, cancer cultures). We elaborated a method for counting cells in low-density cell cultures to calculate the number of cells in the same growth substrate areas during cultivation, and to build cell genealogy trees. We also developed a non-invasive technology for receiving and analysing cells from human hair follicle and urine. It was shown that the cells obtained aged after a two-week cultivation, and therefore were not prone to immortalization, i.e., suitable for use in research for regenerative medicine. The method allows to obtain cell numbers in dynamics and makes it possible to get statistically valid quantitative data by using a minimal number of culture flasks. This approach can be exploited for testing antiproliferative and apoptosis-inducing effects, as well as the action of various substances and their combinations.
Gain Calibration of Current-to-Voltage Converters
Authors: Larason Thomas , Miller C. Cameron
Published: November 2018

Current-to-voltage converters are used in many photometric and radiometric
applications. The calibration of current-to-voltage converters at a few input currents
is not always sufficient to understand the linearity and the bias of a device. Many
devices have structure deviating from a linear response over the operating range of a
gain setting. Measurement services that rely on these devices now have decreased
uncertainties to a level that requires quantifying the uncertainties and understanding
how they propagate. The National Institute of Standards and Technology has developed a
system to calibrate the current-to-voltage conversion factor or “gain” and offset of
these devices for direct current photocurrents. The equipment used for the calibration
is described here, and the results and uncertainties are discussed.
Trabalho, ócio, preguiça: cumpre imaginar Sísifo feliz!
Authors: Romera Valverde Antônio José
Published: November 2018

O ensaio explora aspectos do trabalho humano, fundando-se em contribuições teóricas e remissões à Literatura, de modo a levar águas aos moinhos da heresia firmada contra o trabalho, na linha do elogio crítico e do ataque às apologias mais renitentes. Analisa os nexos entre trabalho, ócio, preguiça e, no limite, ética e política. Sem perder de vista o horizonte histórico do problema.
Un nuevo mundo: ética del sacrificio y fenomenología asubjetiva. Jan Patočka
Authors: Pommier Eric
Published: November 2018

Se trata de presentar aquí la fundamentación ontológica de la ética de Patočka gracias a la cual se puede pensar la posibilidad de un cosmopolitismo. Por ello, planteamos el problema del cosmopolitismo, que nos remite al problema del aparecer de la ética en un mundo dominado por la técnica. Esta preocupación por la fenomenalización de la ética conduce a una tematización del sacrificio que nos hace enfrentar una aporía. Sin embargo, mostramos que la concepción asubjetiva de la fenomenología de Patočka permite solucionarla.
Notas sobre a voluntariedade das ações a partir de Wittgenstein
Authors: Donat Mirian
Published: November 2018

O artigo tece algumas considerações acerca da voluntariedade das ações a partir de observações da filosofia tardia de Wittgenstein. Estas considerações passarão por três momentos: primeiro apresentamos a crítica de Wittgenstein aos modelos causais de explicação da ação voluntária, contra os quais defende uma análise gramatical dos termos ligados à vontade, demonstrando os diferentes lugares que estes ocupam nos jogos de linguagem; depois mostramos que, a partir da compreensão da voluntariedade enquanto expressão de regras gramaticais, pode-se compreender que a voluntariedade “caracteriza” as ações, aproximando esta discussão com a discussão acerca da visão de aspetos e, por fim, mostramos o papel e o lugar do sujeito e da perspectiva de primeira pessoa para a correta compreensão da ação voluntária.
Relação público-privado na educação: produção acadêmica sobre o Instituto Ayrton Senna (2002-2015)
Authors: Silva Fernando Xavier , Jacomini Marcia Aparecida
Published: November 2018

Neste artigo são apresentadas conclusões de revisão bibliográfica sistemática de produções acadêmicas sobre a atuação do Instituto Ayrton Senna (IAS) na educação pública, com base na análise de teses, dissertações e artigos publicados no período de 2002 a 2015. O objetivo da pesquisa foi identificar características e contribuições desses trabalhos, com foco na análise de suas conclusões. O conjunto de trabalhos analisados foi coletado em repositórios e bancos de teses e dissertações de instituições de ensino superior, a partir dos descritores Instituto Ayrton Senna, Fundação Ayrton Senna e IAS. Foram selecionados 64 trabalhos (24 dissertações, seis teses e 34 artigos). Alguns autores das produções analisadas consideraram as parcerias entre o IAS e os municípios positivas, porém, a maior parte dos autores as considerou negativas, porque inseriram valores mercadológicos na escola pública e transformaram o diretor em gerente-gestor, responsável pelos resultados educacionais da escola em que atua.
Funcionamento adaptativo, problemas de comportamento e queixas escolares: percepção de professores
Authors: Sapienza Graziela , Bandeira Laís
Published: November 2018

A percepção do professor acerca do desempenho e do comportamento do aluno em sala de aula influencia em todo o processo de ensino e aprendizagem. O objetivo desta pesquisa foi conhecer as principais queixas para o encaminhamento de escolares à avaliação psicológica e sua relação com aspectos do funcionamento adaptativo e de comportamento em sala de aula, conforme a percepção dos professores. Foram analisados cinquenta prontuários de estudantes encaminhados para um serviço municipal de psicologia. Posteriormente os professores desses alunos responderam ao Teacher Report Form (TRF). Foram identificados três grupos de queixas (G1 — dificuldades de aprendizagem, G2 — problemas de comportamento e G3 — ambas as queixas) que, quando relacionadas aos dados do TRF, mostraram que escolares do G3 são percebidos com mais problemas de comportamento do que os alunos dos outros grupos, principalmente em relação à ansiedade, problemas sociais e isolamento. Esses dados auxiliam o professor na compreensão de aspectos relacionados a cada uma dessas queixas escolares e pode contribuir para a escolha de métodos mais ajustados no processo de ensino e aprendizagem, além de garantir o encaminhamento para um serviço adequado.
O uso do laptop em contexto escolar: um inventário das produções acadêmicas relacionadas ao PROUCA
Authors: Alves Filho Marcos Antonio , Peixoto Joana , Echalar Adda Daniela Lima Figueiredo
Published: November 2018

Na busca de compreender as produções acadêmicas sobre o uso do laptop do PROUCA no ambiente escolar, foi realizado um estado do conhecimento com teses publicadas na Biblioteca Brasileira Digital de Teses e Dissertações (BDTD), no período de 2005 a 2016. Foram encontradas 11 teses que discutem o uso do laptop em contexto escolar brasileiro, que após sistemática análise de seus elementos constituivos, evidenciou três eixos de análise: 1) naturalização da necessidade social da inclusão digital, 2) ênfase na atividade do aluno e 3) uso do laptop para a mudança da prática docente. Os dados nos revelam que estas teses são fundamentadas na lógica do uso dos aparatos digitais na escola como base para o consumo de TIC, na negação das contradições históricas de implementação do PROUCA, por fazerem alusão a uma suposta inclusão promovida pelo uso de laptops e na separação dos produtos da atividade humana (os aparatos tecnológicos) das suas condições materiais de produção e de consumo.
Da “janelinha” para o “janelão”: a relevância de conteúdos qualificados para a educação permanente pelos surdos e sua inclusão transformadora
Authors: Carvalho Jaciara de Sá , Brito Rita Cassia Martins Costa
Published: November 2018

Uma das dificuldades com as quais sujeitos surdos se deparam é o acesso à informação qualificada em audiovisuais, uma vez que recursos como legendas e o trabalho de intérpretes não seriam suficientes para ampla compreensão, pois a maioria não domina a Língua Portuguesa Escrita (LPE) e, ainda que os intérpretes utilizem a Língua Brasileira de Sinais (Libras), há sempre uma tradução. A partir desta problemática, este artigo apresenta uma discussão sobre a importância de conteúdos qualificados para a inclusão social com tecnologias e educação desses sujeitos, considerando dados de uma pesquisa sobre a TV INES, primeira WEB TV no País protagonizada por surdos com programação bilíngue (Libras e Português). Entrevistas com surdos de diferentes níveis de escolaridade apontam para a necessidade de ampliação de conteúdos produzidos por surdos e para surdos como insumo para o desenvolvimento de sua criticidade (FREIRE, 1979) e, assim, para seu processo permanente de educação com tecnologias digitais.
Differential Enriched Scan 2 (DEScan2): a fast pipeline for broad peak analysis
Authors: Righelli Dario , Koberstein John , Zhang Nancy , Angelini Claudia , Peixoto Lucia , Risso Davide
Published: November 2018

Nowadays, the analysis of RNA-seq and BS-Seq can be considered well established, whereas the analysis of broad peaks data as Sono-Seq/ATAC-Seq and histone modification (HM) ChIP-Seq is still challenging. To fill the gap in existing methods, we present DEScan2 a novel bioconductor package [2] for the analysis of broad peaks data. The method consists of three main steps: 1) a peak caller, 2) peak filtering and alignment across replicates and 3) a method to efficiently compute a count matrix of the filtered peaks. Using an already published ATAC-Seq dataset for chromatin accessibility our method shows interesting results, also by comparing it with other well-known tools for this kind of data analysis.
