The impact of Influencer marketing on consumer buying behavior in social networks
Authors: Černikovaitė Miglė
Published: May 2019

Purpose – the purpose of the article is to analyze the impact effect of Influencers marketing on consumer
buying behavior by determining which partnership opportunities are most relevant.
Research methodology – the theoretical analysis of scientific literature and quantitative statistical analysis of empirical
research results.
Findings – the research in Lithuania has shown that before making a decision to purchase a product or a service, most
respondents are actively seeking information in social networks by reading other costumers feedback. Moreover, the
survey reveals that recommendations, comments, shared information about certain brands by Influencers are the most
important factors in changing buying behavior.
Research limitations – the main limitations of research may be the geographical research area – Lithuania and social
networks (Facebook).
Practical implications – understanding of Influencers impact on consumer buying behavior.
Originality/Value – this scientific topic is rather new. Scientists, like Matsumura, Yamamoto, & Tomozawa (2008),
investigated Influencers and Consumer Insights impact in the Blogosphere; Thakur, Srivastava (2015) presented a Conceptual research model of Influencers impact of Customer Satisfaction and Loyalty and etc. However, there is a lack of
research investigating the impact of Influencer marketing on consumer buying behavior. This research aims to fill this
gap in the Lithuanian case

Published: May 2019

Purpose – improving the efficiency of international supply chains via optimizing the functioning of customs terminals.
Research methodology – analysis of the performance of customs terminals.
Findings – simplification of customs control and customs clearance through the application of electronic customs (e-customs) declarations; brings customs procedures in Ukraine closer to European and world standards and significantly facilitates the work of law-abiding foreign economic entities.
Research limitations – today, Ukraine’s customs legislation makes it possible to use electronic declarations (e-declarations) without any restrictions by all willing companies that are registered with the customs authorities and pro-vides for the possibility of filing an e-declaration in all customs regimes without exception. The declarant only needs an electronic digital (e-digital) signature. Upon request, an enterprise may obtain an electronic digital key in the territorial units of the Accredited Key Certification Center for free.
Practical implications – a reduction of customs clearance time.
Originality/Value – an analysis of the work of customs in the territory of Ukraine was conducted, and measures were proposed to optimize the functioning of customs terminals

Authors: Al Majzoub Khaled , Davidavičienė Vida
Published: May 2019

Purpose – to make comparative analysis of the most successful reverse e-logistics’ solution in Asia and Europe to identify models and methods for solving efficiency and sustainability issues in these areas.

Research methodology – the research methodology implemented is composed of literature review, synthesis, and comparative analysis.

Findings – certain solutions implemented such as omni-channels, and Multi-criteria decision making (MCDM) in Asia, and selecting the best third-party reverse logistics providers (3PRLPs), and green suppliers in Europe were able to increase the efficiency of reverse e-logistics’ performance.

Research limitations – the lack of enough researches done in the field of RL in the Middle East created obstacles in double checking the work presented in this paper because more resources are needed to confirm significantly the results. As for future recommendations, further researches should be conducted in the Middle East.

Practical implications – the results found can be implemented in those firms who are still suffering inefficiencies and high costs in their reverse e-logistics’ activities.

Originality/Value – this research made a comparison study between solutions implemented in Europe and Asia in head-to-head comparison in such a way it gave an originalitity of these values since no previous researches and studies were conducted in that comparative way before.

Published: May 2019

Using a global network of small telescopes, we have obtained light curves of Proxima Centauri at 329 observation epochs from 2006 to 2017. The planet Proxima b discovered by Anglada-Escudé et al. with an orbital period of 11.186 days has an a priori transit probability of ∼1.5%; if it transits, the predicted transit depth is about 5 mmag. In Blank et al., we analyzed 96 of our light curves that overlapped with predicted transit ephemerides from previously published tentative transit detections and found no evidence in our data that would corroborate claims of transits with a period of 11.186 days. Here we broaden our analysis, using 262 high-quality light curves from our data set to search for any periodic transit-like events over a range of periods from 1 to 30 days. We also inject a series of simulated planet transits and find that our data are sufficiently sensitive to have detected transits of 5 mmag depth, with recoverability ranging from ∼100% for an orbital period of 1 day to ∼20% for an orbital period of 20 days for the parameter spaces tested. Specifically, at the 11.186-day period and 5 mmag transit depth, we rule out transits in our data with high confidence. We are able to rule out virtually all transits of other planets at periods shorter than 5 days and depths greater than 3 mmag; however, we cannot confidently rule out transits at the period of Proxima b due to incomplete orbital phase coverage and a lack of sensitivity to transits shallower than 4 mmag.

Published: May 2019

Magnetic imprints, the rapid and irreversible evolution of photospheric magnetic fields as feedback from flares in the corona, have been confirmed by many previous studies. These studies showed that the horizontal field will permanently increase at the polarity inversion line (PIL) after eruptions, indicating that a more horizontal geometry of the photospheric magnetic field is produced. In this study, we analyze 20 X-class flares since the launch of the Solar Dynamics Observatory in 15 active regions with heliographic angles no greater than 45°. We observe clear magnetic imprints in 16 flares, whereas 4 flares are exceptional. The imprint regions of the horizontal field are located not only at the PIL but also at sunspot penumbra with strong vertical fields. Making use of the observed mass and speed of the corresponding coronal mass ejections (CMEs), we find that the CMEs with larger momenta are associated with stronger magnetic imprints. Furthermore, a linear relationship, with a Kendall’s Tau-b coefficient 0.54, between the CME momentum and the change of Lorentz force, is revealed. Based on that, we quantify the back reaction time to be ∼70 s, with a 90% confidence interval from about 50 to 90 s.

We report on the optical properties of infrared (IR)-bright dust-obscured galaxies (DOGs) that are defined as

. Because supermassive black holes (SMBHs) in IR-bright DOGs are expected to be rapidly growing in the major-merger scenario, they provide useful clues for understanding the coevolution of SMBHs and their host galaxies. However, the optical properties of IR-bright DOGs remain unclear because the optical emission of a DOG is very faint. By combining ∼105 deg2 images of the optical, near-IR, and mid-IR data obtained from the Subaru Hyper Suprime-Cam (HSC) survey, the VISTA VIKING survey, and the Wide-field Infrared Survey Explorer all-sky survey, respectively, 571 IR-bright DOGs were selected. We found that IR-bright DOGs show a redder (g − z)AB color than do other populations of dusty galaxies, such as ultraluminous IR galaxies (ULIRGs) at a similar redshift, with a significantly large dispersion. Among the selected DOGs, star formation (SF)-dominated DOGs show a relatively red color, while active galactic nucleus (AGN)-dominated DOGs show a rather blue color in optical. This result is consistent with the idea that the relative AGN contribution in the optical emission becomes more significant at a later stage in the major-merger scenario. We discovered eight IR-bright DOGs showing a significant blue excess in blue HSC bands. This blue excess can be interpreted as a leaked AGN emission that is either a directly leaking or a scattered AGN emission, as proposed for some blue-excess Hot DOGs in earlier studies.
The Heavy-element Content Trend of Planets: A Tracer of Their Formation Sites
Authors: Hasegawa Yasuhiro , Hansen Bradley M. S. , Vasisht Gautam
Published: May 2019

Identification of the main planet formation site is fundamental to understanding how planets form and migrate to their current locations. We consider the heavy-element content trend of observed exoplanets, derived from improved measurements of mass and radius, and explore how this trend can be used as a tracer of their formation sites. Using gas accretion recipes obtained from hydrodynamical simulations, we confirm that the disk-limited gas accretion regime is most important for reproducing the trend. Given that such a regime is specified by two characteristic masses of planets, we compute these masses as a function of the distance (r) from the central star, and then examine how the regime appears in the mass–semimajor axis diagram. Our results show that a plausible solid accretion region emerges at r ≃ 0.6 au and expands with increasing r, using the conventional disk model. Given that exoplanets that possess the heavy-element content trend distribute currently near their central stars, our results imply the importance of planetary migration that would occur after solid accretion onto planets might be nearly completed at r ≥ 0.6 au. Self-consistent simulations would be needed to verify the predictions herein.

Authors: Guarino Fabio M. , Crottini Angelica , Mezzasalma Marcello , Randrianirina Jasmin E. , Andreone Franco
Published: May 2019

We characterized the body size (as snout-vent length), age, sexual size dimorphism, and growth rate in a population of one of the larger riparian frog from Madagascar (Mantidactylusgrandidieri) from a rainforest patch close to Vevembe, SE Madagascar. We identified a significant female-biased sexual size dimorphism. Age was estimated using phalangeal skeletochronology and was significantly higher in females than in males. Modal age class turned out to be 4 years in both sexes but a large percentage of adult females (75%) fell in the 5–6 years-old classes, while no male exceeded 4 years. We here report M.grandidieri as a medium-long-lived anuran species. Von Bertalanffy’s model showed similar growth trajectories between the sexes although the growth coefficient in females (k = 0.335) was slightly but not significantly higher than in males (k = 0.329).
Broad seasonal changes in thermoregulation of Podarcis lilfordi (Squamata, Lacertidae) at Binicodrell islet (Menorca, Spain)
Authors: Ortega Zaida , Mencía Abraham , Giroux Aline , Pérez-Mellado Valentín
Published: May 2019

Most lizards maintain quite constant body temperatures by behavioural means. Seasonal variations of environmental factors, such as temperature, sunlight exposure and wind intensity, influence lizard thermoregulatory abilities. Understanding how seasonal environmental shifts influence lizards’ thermoregulation helps us to know how they deal behaviourally with environmental changes, in general. We examined seasonal shifts (spring vs. summer) in behavioural thermoregulation in Podarcislilfordi from Binicodrell islet (Menorca, Spain). Operative temperatures varied between microhabitats and seasons, being lower in spring than in summer, regardless of sunlight exposure. Lizard body temperatures were also lower in spring than in summer. Lizards used sunny microhabitats more frequently in spring and shaded areas in summer. Habitat thermal quality was similar during both seasons, but lizards thermoregulated less accurately in spring than in summer. Thermoregulatory effectiveness was low in spring (0.28) and moderate in summer (0.76). In comparison with previously published results, our findings showed the marked seasonal variation in the effectiveness of thermoregulation amongst island populations, which should be considered in future comparative studies.
Mélancolie des origines

L'auteure propose dans cet article une interprétation originale du mythe d'Electre et Oreste. Cet épisode de la tragédie grecque, pourrait‑il constituer, du point de vue de la psychanalyse, un cas  princeps  et structural ? Pourrait‑on l'élever, comme l'affirme Carl Gustav Jung, au même rang que le complexe d'Œdipe ? Freud l'avait écarté et il semble en effet difficile de penser le « matricide » sans s'être interrogé sur ce rejet du mythe d'Electre comme équivalent symbolique féminin de celui d'Œdipe.

Œuvre inaugurale du théâtre ibérique, elle interroge toujours notre modernité. Elle persiste dans son énigme : elle n'était pas nécessaire dans l'intrigue amoureuse de Calixto et Mélibée, mais elle est devenue le symbole incarné de la séduction et de ses excès. L'entremetteuse diabolique est une magicienne. Sa jouissance est la langue. Elle se perd et elle égare les amants dans la passion. Elle est une mère-furie vouée à la destruction, qui n'admet aucune loi. Elle cherche sans cesse la profanation du sacré. Elle est un signe de l'irrémédiable, d'une folie originaire, d'une passion sans remède.

Authors: Liu Suxia , Zhu Yingming , Wang Weiqiang , Pei Yu , Du Kuanqi
Published: May 2019

To analyze the environmental pollution effects elicited by industrial agglomeration, a spatial econometric model is constructed based on the Green Solow model. Using data derived from 285 Chinese cities between 2003and 2014, the global Moran'I and local bivariate LISA agglomeration map demonstrates that there is significant correlation between industrial agglomeration and industrial pollution discharge. Then, the spatial Durbin model (SDM) is built and the empirical results are as follows. First, inter-city industrial pollution discharge has a demonstration effect. Cites in the same region should take measures to cooperate to lower industrial pollution discharge. Second, the relationship between the local cities' industrial agglomeration and the local cities' industrial pollution discharge fits the inverted “U” curve. While the neighboring cities' industrial agglomeration will decrease the local cities' industrial pollution discharge. So, measures should be taken to increase the industrial agglomeration degree in the long run.

Published: May 2019

Motivated by the fact that human visionary intelligence plays a vital role in guiding many of the agriculture practices, this article represents an effective use of machine vision technology for estimating plant morphological features to ascertain its growth and health conditions. An alternative to traditional, manual and time-consuming testing methods of plant growth parameters, a novel online plant vision system is proposed and developed on the platform of virtual instrumentation. Deployed in real time, the system acquires plant images using digital camera and communicates the raw image to host PC on Wi-Fi network. The dedicated application software with plant user interface, effective image processing and analysis algorithms, loads the plant images, extracts and estimates certain morphological features of the plant such as plant height, leaf area, detection of flower onset and fall foliage. The system was tested and validated under real-time conditions using different plants and leaves. Further, the performance of the system was statistically analysed to show promising results.

Authors: Maya Gopal P S  , Bhargavi R
Published: May 2019

In agriculture, crop yield prediction is critical. Crop yield depends on various features including geographic, climate and biological. This research article discusses five Feature Selection (FS) algorithms namely Sequential Forward FS, Sequential Backward Elimination FS, Correlation based FS, Random Forest Variable Importance and the Variance Inflation Factor algorithm for feature selection. Data used for the analysis was drawn from secondary sources of the Tamil Nadu state Agriculture Department for a period of 30 years. 75% of data was used for training and 25% data was used for testing. The performance of the feature selection algorithms are evaluated by Multiple Linear Regression. RMSE, MAE, R and RRMSE metrics are calculated for the feature selection algorithms. The adjusted R2 was used to find the optimum feature subset. Also, the time complexity of the algorithms was considered for the computation. The selected features are applied to Multilinear regression, Artificial Neural Network and M5Prime. MLR gives 85% of accuracy by using the features which are selected by SFFS algorithm.
Design of Secure Image Fusion Technique Using Cloud for Privacy-Preserving and Copyright Protection
Authors: Kumar Ashwani
Published: May 2019

Nowadays, the use of digital content or digital media is increasing day by day. Therefore, there is a need to protect the digital document from both unauthorized users and authorized users. The digital document should be protected from authorized users who try to redistribute it illegally. Digital watermarking techniques along with cryptography are insufficient to ensure an adequate level of security of digital media. The security of the transferring digital data in the modern world is also a big challenge because there is a high risk of security breaches. In this article, a secure technique of image fusion using hybrid domains (spatial and frequency) for privacy preserving and copyright protection is proposed. The proposed method provides a secure technique for the digital content in cloud environment. Two cloud services are used to develop this work, which eliminates the role of a trusted third party (TTP). First is the design of an infrastructure as a service (IaaS) to store different images with encryption processes to speed up the image fusion process and save storage space. Second, a Platform as a Service (PaaS) is used to enable the digital content to improve computation power and to increase the bandwidth. The prime objective of the proposed scheme is to transfer the digital media between a service provider and customer in a secure way using a hybrid domain along with cloud storage. Imperceptibility and robustness measures are used to calculate the performance of the proposed approach.

Authors: Chansuvarn Woravith
Published: May 2019

The aim of this work was to validate the sample preparation using a microwave digestion for determination of total arsenic in a spiked soil. Graphite furnace atomic absorption spectrophotometer (GFAAS) technique was used to determine the total arsenic using palladium nitrate as a modifier agent. The instrumental detection was performed under the condition steps of drying, ashing, atomizing and cleaning to be 100, 1200, 2250 and 2600°C, respectively. The external calibration curve was constructed using the automatic program with the master standard of 20 ppb arsenic solution. It was found that linearity range was in the range of 1 to 20 ppb with R2>0.999. The LOD and LOQ were 0.10 and 1.0 ppb, respectively. Based on two microwave digestion programs, the total arsenic obtained from the preparation method with HF and without HF were also compared. The result showed that the arsenic content obtained from both methods did not significantly different at the 95% confidence limit. The percentage of recovery was 80.3 and 82.3% for the spiked samples of 2.5 and 10 ppb, respectively. The relative standard deviation was 2.15% (n=11). The results of this work confirm that the preparation method using microwave digestion provided the more advantages, such as rapid, a little volume of reagents, completely digestion.
Improvement of Mechanical Properties and Water Absorption in Wheat Gluten by Epoxidized Natural Rubber
Authors: Chaochanchaikul Kantima
Published: May 2019

TThe aims of this research work were to improve touhgness and water resistance of wheat gluten (WG) by epoxidized natural rubber (ENR) compared to glycerol. WG specimens were mixed and prepared by internal mixer and compression molding machine, respectively. ENR and glycerol were varied from 10 to 40 wt%. Effects of modifier types and contents on WG were evaluated by tensile, impact and water absorption testings and microstructure and thermal analyses. The increase of ENR or glycerol contents led to the increase of toughness by considering the increase of impact strength and elongation at break. Glass transition temperature of WG tended to decrease with the increase of ENR or glycerol contents, especially for glycerol. The presence of glycerol affected to the decomposition temperature values whereas ENR did not affect to decomposition. ENR improved water resistant of WG specimen but trend of glycerol showed the opposite behavior. Weight loss of modified WG with glycerol was found at immersion time of 1440 min.

Sulfonated graphene oxide (sGO) was used as a filler to enhance performance of sulfonated poly(ether ether ketone)(sPEEK) membrane. The sGO was firstly prepared by treating graphene oxides (GO) with sulfanilic acid at 70 °C for 20 h. The sGO was characterized by FTIR and XPS techniques. Composite membranes of various amount of sGO were fabricated via solution casting method. The properties of composite membranes were investigated by measuring ion exchange capacity (IEC), water uptake, ion conductivity and vanadium ion permeability. From the results, it was found that the IEC and water uptake of the membranes increased after adding the sGO. Ion conductivity of the sPEEK membrane also increased from 8.94*10-3 Scm-1 to 10.55*10-3 Scm-1. Moreover, permeability of vanadyl sulfate (VOSO4) through the composite membranes were decreased. These composite membranes exhibit great potential for vanadium redox flow batteries application.

Published: May 2019

According to their wonderful properties, carbon nanotubes (CNTs) have been well known for decades. The synthesis process and catalyst deposition method have also drawn attention to control the nanotube structure and properties. Sputtering method is then one promising option to grow the nanotubes in mass production. This method is, however, still costly. Here, we have presented a simple low-cost custom-made DC magnetron sputtering for catalyst thin film deposition. Three different metal thin films (Fe, Ni, Cu) deposited on Si substrates have been employed to investigate nanotube production. Prior to deposition of the catalysts, Al was used as supporting layer. (Al/Fe, Al/Ni, Al/Cu). CNTs were grown by chemical vapor deposition process at 800°C. Ethanol was preliminary used as a carbon source. It was found that CNTs could be successfully grown from only Al/Ni catalysts in our system with the diameter of approximately 200 nm, where the rest of samples were not observed. In addition, vertical-aligned CNTs with the thickness of about 10 μm could be obtained when acetylene was replaced instead of ethanol with reducing partial pressure of the feedstock. A large D-band at 1338 cm-1 with broader G-band at 1582 cm-1 from Raman spectra give a rise to multi layers growth of sp2 carbon walls. Such dimension suggests that it is the characteristic of multi-walled carbon nanotubes.

Published: May 2019

This study was conducted to analyze the correlation between traits of fruit mulberry from 71 hybrid accessions. The results revealed that the fruit yield (FY) had intermediately positive correlated to branch per trunk (BPT, r = 0.46). Fruit width (FWI) had very highly positive correlated to fruit length (FL, r = 0.77) and fruit weight (FWE, r = 0.86). Fruit length (FL) had highly positive correlated to fruit weight (FWE, r = 0.91) but had slightly negative correlated to bud per branch (BPB, r = -0.28). Fruit weight (FWE) had slightly positive correlated to branch length per trunk (BLPT, r = 0.27) but had slightly negative correlated to bud per branch (BPB, r = -0.29). Finally, branch length per trunk (BLPT) had intermediately negative correlated to bud per branch (BPB, r = -0.39). Additionally, the economic traits which had highly positive direct effect through fruit yield was branch length per trunk (BLPT, path coefficient = 0.428).

Chronic granulomatous disease (CGD) is a primary immunodeficiency disease caused by defects in the leukocyte NADP oxidase. We previously reported that sarcoplasmic/endoplasmic reticulum calcium pump (SERCA) inhibitors could be used to rescue mutant H338Y-gp91phox protein of a particular type of CGD with a CybbC1024T mutation, leading to endoplasmic reticulum (ER) retention of the mutant protein. In this study, we developed a novel mouse model with the CybbC1024T mutation on a Cybb knockout background and investigated the therapeutic effects of ER-targeted delivery of the SERCA inhibitor, curcumin, with poly(lactic-coglycolic acid) (PLGA) nanoparticles (NPs). We found that PLGA encapsulation improved the efficacy of curcumin as a SERCA inhibitor to induce ER calcium release. ER-targeting curcumin-loaded PLGA NPs reduced and delayed extracellular calcium entry and protected the cells from mitochondrial damage and apoptosis. In vivo studies showed that ER-targeting curcumin-loaded PLGA NPs treatment enhanced neutrophil gp91phox expression, ROS production and peritoneal bacterial clearance ability of the CybbC1024T transgenic Cybb−/− mice. Our findings indicate that ER-targeted delivery of curcumin not only rescues ER-retained H338Y-gp91phox protein, and hence leukocyte function, but also enhances the bioavailability and reduces cytotoxicity. Modulation of ER function by using organelle-targeted NPs may be a promising strategy to improve the therapeutic potential of curcumin as a treatment for CGD.

Induction of programmed DNA damage and its recognition and repair are fundamental for B cell development. The ssDNA-binding protein SSB1 has been described in human cells as essential for the recognition and repair of DNA damage. To study its relevance for B cells, we recently developed Ssb1−/− and conditional Ssb1−/− mice. Although SSB1 loss did not affect B cell development, Ssb1−/− cells exhibited compensatory expression of its homolog SSB2. We have now generated Ssb2−/− mice and show in this study that SSB2 is also dispensable for B cell development and DNA damage response activation. In contrast to the single loss of Ssb1 or Ssb2, however, combined SSB1/2 deficiency caused a defect in early B cell development. We relate this to the sensitivity of B cell precursors as mature B cells largely tolerated their loss. Toxicity of combined genetic SSB1/2 loss can be rescued by ectopic expression of either SSB1 or SSB2, mimicked by expression of SSB1 ssDNA-binding mutants, and attenuated by BCL2-mediated suppression of apoptosis. SSB1/2 loss in B cell precursors further caused increased exposure of ssDNA associated with disruption of genome fragile sites, inefficient cell cycle progression, and increased DNA damage if apoptosis is suppressed. As such, our results establish SSB1/2 as safeguards of B cell development and unveil their differential requirement in immature and mature B lymphocytes.

Published: May 2019

Bone metastases is one of the most common causes of pain in cancer patients and have a significant effect on their quality of life. The most common symptom of bone metastases is pain that gradually develops. Morphine is used to relieve pain in these patients, but poorly accepted due to its adverse events. Therefore, the current study was aimed to compare the effect of sublingual buprenorphine, with certainly lower complications with morphine. Fourth patients were divided into 2 groups. In group A, metastatic cancer patients received 2.5 mg of intravenous morphine. Furthermore, in group B, sublingual tablet of buprenorphine (one-fourth of a 500 μg tablet) was administered sublingually. Pain was measured 15, 30, and 45 minutes after the onset of pain using visual analog scale ruler. Based on the obtained data, two groups A and B were compared using SPSS 23 software. There was a significant difference between the patient's pain intensity after 15 and 30 minutes from the onset of pain in both groups. Due to the fact that the duration of the effect of morphine is 3-4 hours and the duration of the effect of sublingual buprenorphine is 6-8 hours, morphine showed fast acting forms of opioids (P= 0.001). The required dose level on the first day was similar in both groups and there was no statistically significant difference between the two groups. While on the second and third days, the median dose in group A (morphine) was greater than group B (buprenorphine), indicating prolonged duration of action for buprenorphine compared with morphine, thus requiring lower subsequent doses. The results of this study suggested that sublingual buprenorphine is a higher effective drug compared to intravenous morphine during and after operation. With regard to easy and painless administration, it seems that its use can be useful in controlling pain due to bone metastases in cancer patients.

Microsurgical treatment of paraclinoid aneurysms by extradural anterior clinoidectomy: The fujita experience
Authors: Yamada Yasuhiro , Ansari Ahmed , Sae-Ngow Treepob , Tanaka Riki , Kawase Tsukasa , Kalyan Sai , Kato Yoko
Published: May 2019

Introduction: Paraclinoid aneurysms pose technical difficulty in their approach, mainly because of their close proximity to neurovascular structures, deeper location, and a smaller corridor. Extradural anterior clinoidectomy is a highly beneficial technique in such cases, making more space to deal with these aneurysms. We describe our method of performing extradural anterior clinoidectomy in such patients. Materials and Methods: A total of 33 cases of paraclinoid internal carotid artery aneurysms presenting to Fujita Health University Banbuntane Hospital, Japan, were included. Females comprised the majority with 32 cases; the mean age was 54.8 years (range: 35–74 years). The mean size of the paraclinoid aneurysm was 5.3 mm (range: 3–12 mm). Results: Nine paraclinoid aneurysms were found projecting dorsally, 7 laterally, and 17 medially (Kazuhiko Kyoshim et al's. classification). An immediate complete occlusion rate of 100% was present. Visual disturbance was found in 6.2% of our patients. One of our patients developed permanent loss of vision. Conclusion: Extradural anterior clinoidectomy enables a better exposure to paraclinoid aneurysms. Precise anatomical knowledge along with microsurgical tactics is required to prevent and manage potential complications to achieve good outcomes.
Primary neuroendocrine tumor of the lumbar spine: Rare tumor mimicking nerve sheath tumor of the spine
Authors: Kumar Sanjay , Maheshwari Vikas , Mukherjee Aishik , Raman Deep
Published: May 2019

Neuroendocrine tumors (Carcinoid tumors) generally arise from enterochromaffin cells of gut and bronchi. Primary carcinoid tumors of spine are extremely rare and have been described in sacrum and coccyx. Primary carcinoid tumors involving the spinal cord are still rarer, and review of literature revealed only two cases reported. Our patient a 39-year-old male had diagnosed as a case of nerve sheath tumor (intradural extramedullary) at LV4 region on neuroimaging. However, postoperatively, the tumor turned out to be a rare primary spinal carcinoid tumor on histopathological examination and immunohistochemical staining. Work up to rule out any other site in the body was negative. To the best of our knowledge, this is the first case of primary carcinoid tumor of the lumbar spine.

A 75-year-old man presented with right-sided hemiplegia and was diagnosed with a left middle cerebral artery occlusion. He underwent endovascular thrombectomy, and a bulge was found. A modified pigtail-shaped microguidewire (MPMGW) proved useful for diagnosis because it allowed differentiation between the occluded artery and a saccular aneurysm as the etiology. When a clot was partially retrieved, a previously unidentified vessel dilatation appeared. The dilatation origin was unclear and could have resulted from either the occluded artery or an unruptured saccular aneurysm. We tried to navigate the MPMGW into the bulging area. The patient showed unusual body movement attributed to pain and the dilatation was diagnosed as an aneurysm. Subsequent 3-dimensional angiography revealed a recanalized artery and the aneurysm. With no subarachnoid hemorrhage or extravasation of the contrast medium. The hemiplegia dramatically improved. An MPMGW may be useful in acute thrombectomy where the target vessel cannot be visualized during the procedure.

A evolução tecnológica das máquinas de colheita de madeira tem permitido a ampliação da área de desbaste seletivo nos povoamentos florestais, com ganhos de produtividade, porém com riscos de afetar a qualidade do trabalho. Neste contexto, objetivou-se avaliar a qualidade da operação de colheita florestal com harvester em povoamentos de Pinus taeda submetidos a dois modelos de desbaste: (1) corte sistemático da quinta linha e seletivo nas linhas adjacentes e (2) corte sistemático da sétima linha e seletivo nas adjacentes. A qualidade foi avaliada pela mensuração da altura das cepas e comprimento das toras nos sortimentos serraria, laminação e celulose. Os valores obtidos foram analisados por meio de histogramas e as médias comparadas com as dimensões pré-estabelecidas por meio do teste Wilcoxon (α ≤ 0,05). As alturas de 90% das cepas superaram o valor pré-estabelecido, com médias de 12,5 e 12,9 cm, acarretando em volume de madeira desperdiçado de 0,50 e 0,62 m3 ha-1 nos modelos de desbaste 1 e 2, respectivamente. Os comprimentos das toras de serraria e laminação, nos dois modelos de desbaste, foram superiores ao esperado, enquanto os valores para toras para celulose mostraram-se inferiores estatisticamente em relação ao pré-estabelecido.
My film in your pocket: an analysis of user interactions with films and copyright law
Authors: Ekiz Oğulcan
Published: May 2019

This article questions the author-centred conceptualization of copyright's subject matter in defining the scope of protection. It focuses on films, the medium's communicative nature, and user interactions with films in the digital age. The analysis starts with Kant's definition of a book as a ‘public speech’ and adapts it to films. The article states that the publicness of the medium comes with user expectations. It states that, in many cases, the audience's interaction with films starts with the expectation of a further communication through the work. The article then explores the intercommunication of the audience, its transformation in the digital age, and its role in shaping our cultural landscape. The conclusion is that, in order to answer the demands of the new habits of communications, new ways of research, and any novelty that comes with future technologies, copyright law needs to acknowledge the participatory nature of user interactions with cultural works and how those interactions shape our culture.
