Authors: Alganci Ugur , Sertel Elif , Kaya Sinasi
Published: August 2018

Identification of fruit trees and determination of their spatial distribution is an important task for several agricultural activities including fruit yield estimation, irrigation planning, disease management and supporting agricultural policies. This research aims to determine spatial distribution of olive trees at parcel level by using geographic object based image analysis (GEOBIA) and very high resolution satellite images. A pilot area located in the Aegean region of Turkey was selected to conduct research considering the massive amount of olive production within the area. GEOBIA based decision-tree classification was applied to accurately map perennial crop parcel boundaries. After applying multi-resolution segmentation to create image objects, thresholds determined from spectral properties of image objects were integrated into the decision tree to ensure accurate mapping of olive trees. Accuracy assessment was conducted by comparing a highly accurate parcel database with classification results and efficiency of parcel identification and areal information derivation were evaluated. Our results indicated that, decision-tree oriented GEOBIA classification provided sufficient results for determination of olive trees with 90 percent classification accuracy and differentiating them from non- vegetated areas and annual crops. Area estimation and parcel detection performances of the method were also acceptable by providing 0.11 and 0.08 relative errors respectively.

Published: August 2018

Indonesia dan Tiongkok merupakan pelaku utama perdagangan batu bara dunia. Indonesia adalah eksportir batu bara terbesar dan pemasok utama kebutuhan batu bara Tiongkok, sedangkan Tiongkok adalah importir batu bara terbesar di dunia. Kebijakan tarif impor nol persen pada komoditas batu bara yang diterapkan Tiongkok pada Januari 2008, berdampak pada meningkatnya ekspor batu bara Indonesia ke Tiongkok. Namun, setelah Tiongkok mengeluarkan kebijakan Air Pollution Prevention and Control Action Plan, ekspor batu bara Indonesia ke Tiongkok mulai menurun pada tahun 2014. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh kebijakan tarif impor nol persen dan Air Pollution Prevention and Control Action Plan terhadap ekspor batu bara Indonesia ke Tiongkok. Metode yang digunakan dalam penelitian ini adalah analisis intervensi multi input. Data yang digunakan berasal dari Badan Pusat Statistik (BPS). Hasil dari penelitian menunjukkan bahwa kebijakan tarif impor nol persen yang diterapkan oleh Tiongkok memiliki pengaruh yang signifikan positif dan permanen terhadap ekspor batu bara Indonesia ke Tiongkok. Sementara itu, kebijakan Air Pollution Prevention and Control Action Plan memiliki pengaruh yang signifikan negatif dan permanen. Rekomendasi kebijakan adalah implementasi kebijakan tentang standar minimum kualitas batu bara yang dihasilkan. Dengan demikian, kualitas ekspor batu bara Indonesia dapat menyesuaikan spesifikasi permintaan pasar dari negara pengimpor yang menerapkan kebijakan pengendalian pencemaran udara. Indonesia and China are the main actors of world coal trading. Indonesia is the largest coal exporter and the main supplier of Chinese coal needs, while China is the world's largest coal importer. The zero import tariff policy on coal commodities applied by China in January 2008, has an impact on increasing Indonesian coal exports to China. However, after China issued its policy of Air Pollution Prevention and Control Action Plan, Indonesian coal exports to China began to decline in 2014. The objective of this research is to study the influence of zero import tariff policy and Air Pollution Prevention and Control Action Plan to the Indonesian coal exports to China. The method used in this research is the multi-input intervention analysis. Data used are developed from BPS. The results show that the zero import tariff policy applied by China has significantly positive and permanent effect on Indonesian coal exports to China. Meanwhile, the policy of Air Pollution Prevention and Control Action Plan has significantly negative and permanent effect. Policy recommendation is the implementation of policy about minimum standards of coal quality that may be produced. Thus, Indonesian coal exports quality will able to adjust market demand specification from importing countries that implement policies about pollution control.
Telemental and Telebehavioral Health Considerations: A 50-State Analysis on the Development of Telehealth Policy
Authors: Lerman Amy F. , Kim Daniel , Ozinal Francesca R. , Thompson Theresa E.
Published: August 2018

Contemporary healthcare delivery models have a patient-centered approach, a focus on integrating the various types of services patients need, an emphasis on interdisciplinary treatment teams, and a commitment to adopting innovative technologies. Increasing utilization of telehealth technologies has helped foster these contemporary service delivery models by improving access to healthcare services, leveraging the expertise of specialty providers to the point-of-service, and enhancing opportunities for healthcare professional and consumer education. As such, telehealth delivery models have become mainstream and viable solution for healthcare providers, physicians, and employers. According to an August 2016 report from the U.S. Department of Health and Human Services, an estimated 61% of healthcare institutions use some form of telehealth technology, and between 40% and 50% of all hospitals in the United States employ some form of telehealth technology. 1Following suit, the provision of telebehavioral or “telemental” health services continue to trend upward, as behavioral health providers become more interested in utilizing telehealth platforms to connect with their patients. Mental illness affects millions of individuals in the U.S., from all walks of life and across all age groups, contributing significantly to the burdens of disease.2 While mental illness can be recurrent and serious, often it is treatable, provided affected individuals have access to necessary resources. Patients surveyed regarding their use of telemental health services express consistent and affirmative beliefs that telemental health services provide positive benefits. Surveys report little or no difference in levels of patient satisfaction compared to face-to-face interactions between patients and their behavioral health providers.3,4 As states continue to support and expand the exciting benefits telehealth technologies and services offer, our legislators, healthcare systems, and regulatory bodies are being tasked with working together to navigate the numerous legal and regulatory issues that come with it. Epstein Becker Green (“EBG”) recently released an Appendix to its “50-State Survey of Telemental/Telebehavioral Health (2016),” with new and updated analysis on the laws, regulations, and regulatory policies affecting the practice of telemental/telebehavioral health in all 50 states and the District of Columbia.5 The 2017 Appendix reflects the incredibly active legislative efforts in most states with respect to the provision of telehealth services. In fact, only two states, Connecticut and Massachusetts, have not made changes to their legal and regulatory framework since the 2016 Survey. This suggests a lot of policy activity among states to regulate and provide meaningful guidance to telehealth providers.

Bedrock Fracture Influences on Geomorphic Process and Form Across Process Domains and Scales
Authors: Scott Daniel , Wohl Ellen
Published: August 2018

Fractures are discontinuities in rock that can be exploited by erosion. Fractures regulate cohesion, profoundly affecting the rate, style, and location of Earth surface processes. By modulating the spatial distribution of erodibility, fractures can focus erosion and set the shape of features from scales of fluvial bedforms to entire landscapes. Although early investigation focused on fractures as features that influence the orientation and location of landforms, recent work has started to discern the mechanisms by which fractures influence the erodibility of bedrock. As numerical modeling and field measurement techniques improve, it is rapidly becoming feasible to determine how fractures influence geomorphic processes, as opposed to when or where. However, progress is hampered by a lack of research coordination across scales and process domains. We review studies from hillslope, glacial, fluvial, and coastal domains from the scale of reaches and outcrops to entire landscapes. We then synthesize this work to highlight similarities across domains and scales and suggest knowledge gaps, opportunities, and methodological challenges that need to be solved. By integrating knowledge across domains and scales, we present a more holistic conceptualization of fracture influences on geomorphic processes. This conceptualization enables a more unified framework for future investigation into fracture influences on Earth surface dynamics.
Manger dans les transports urbains : un comportement à déconseiller pour la santé et l’hygiène ?
Authors: Moustafa Khaled
Published: August 2018

Regular commuters of public transportation are chronically exposed to sanitary issues and pollution particles that can get into the body through three main ways: breathing, eating and skin pores. While it is hardly conceivable to completely stop particulate matters to get into the body via respiration and skin pores– one cannot stop to breathe or to close his body pores in public transports – it is fully possible to reduce inhalable doses of pollutants by avoiding food consumption in urban mass transit systems that usually serve short and endurable distances in local municipalities. Recommending against eating food on public transports should produce positive outcomes for the sanitary conditions of the transportation means itself and for the health of passengers.
Assessment of Root Plate Structure in Wind-Thrown Trees of Melia dubia
Authors: Arunkumar A. N. , Chauhan Shakti
Published: August 2018

Root plays a significant role in tree growth and development and information pertaining to spread of the root and its depth will be useful for establishing plantations. Most of the root studies are generally carried out in trees growing in urban areas in avenues, but limited studies are carried out in plantations. Being an underground part of the tree, there are inherent difficulties in understanding root architecture. Uprooting of trees due to storm or wind damage provides an ideal opportunity to obtain critical understanding about tree roots. Such study has been carried out in an 11 year old storm ravaged Melia dubia plantation in Punjab, India. Field observations such as tree girth, root girth, root plate width and depth was recorded on uprooted trees. A large variability was recorded for all the traits. Root plate width and depth ranged from 1.42 to 5.17 m and 0.75 to 2.50 m, respectively. A strong positive relationship between tree girth and primary root girth, root plate width and depth identified in this study provides base line information which can be used while establishing M. dubia plantations.Keywords: Melia dubia, root plate, root width, root depth, wind-thrown
Transatlantic Intersections: The Role of Ralph Waldo Emerson in the Dissemination of Blakean Thought into the Poetry of Walt Whitman
Authors: Davidson Ryan J
Published: August 2018

Whitman quoted no one in his poetry, at least not directly, as Matt Miller convincingly mgues in Collage of Myself However, Whitman was not above making use of the work of other writers in his poetry. It is through Whitman's early reading in conjunction with his collage approach to composition that he came to create Leaves of Grass as something which appears wholly original, but which resonates with so many echoes. It is often argued that Ralph Waldo Emerson is one of the most important influences on Whitman 's Leaves of Grass. The extent and significance of Emerson 's influence has been a subject of inquiry' since the advent of Whitman scholarship. This text will focus on Emerson's essays and lectures as the main influences on Whitman which can be read as providing a mediating influence between Blake and Whitman.
“Watch the Blood-Soaked Old General in Action”: Blochian Atheism, Exodus, and Utopia in Doctor Who
Authors: Aldridge Casey
Published: August 2018

This article reads the eighth series of modern Doctor Who alongside Ernst Bloch's Atheism in Christianity. Applying Bloch's motifs of utopianism, God on High, and God of Exodus, it suggests that Doctor Who—and, to a lesser degree, Torchwood: Children of the Earth—presents a narrative that is at once deeply formed by atheist materialism and Christian messianism. Through the character analysis of the Doctor as well as secondary and tertiary characters, this article posits that both the atheist–Christian theology of Bloch and recent turns in Doctor Who fundamentally require the dissolution of all polity and ethical dimensions within religion. Whereas most analyses of the Doctor as a Christ figure examine Doctor Who's third series, this article does so with a focus on the tendencies toward exodus and liberation present in the eighth series. In doing so, it aims to challenge the assumptions of previous studies that have placed Doctor Who's atheism in tension with its Christian imagery and to suggest Bloch's model as a more helpful tool for thinking about the Doctor as a deified protagonist with both atheist and Christian characteristics. This work seeks to consider atheism and theism as forces that can and do exist concurrently in science fiction and Marxist theory, taking shape in a terrain that is neither exclusively Christian nor exclusively atheist and which is made possible through the theoretical vehicles of deification and theodicy.

Published: August 2018

OBJECTIVE

The endoscopic endonasal transcavernous approach with interdural pituitary transposition provides surgical access to the posterior clinoids and interpeduncular cistern. Prior to posterior clinoidectomy, selective coagulation and transection of the inferior hypophyseal artery (IHA) is recommended to prevent uncontrolled tearing of the artery and its avulsion from the wall of the cavernous carotid artery. The authors’ preliminary experience has shown that unilateral sacrifice of the IHA caused no permanent endocrine dysfunction. In this study, they investigated the pituitary function in the setting of bilateral sacrifice of IHAs and pituitary transposition.

METHODS

All patients with normal preoperative pituitary function who underwent endoscopic endonasal bilateral posterior clinoidectomy with bilateral IHA sacrifice between March 2010 and December 2016 were included and retrospectively evaluated. All data regarding pituitary function were collected. The degree of pituitary gland manipulation was estimated based on tumor size on preoperative MRI. An angle between a line from the point where the gland meets the floor of the sella to the highest point of the tumor and the horizontal plane of the sellar floor, or access angle, was also measured. Posterior pituitary bright spots on pre- and postoperative T1-weighted MRI were also reported.

RESULTS

Twenty patients had bilateral transcavernous posterior clinoidectomies with coagulation of both IHAs. There were 13 chordomas, 3 epidermoid cysts, 2 chondrosarcomas, 1 meningioma, and 1 hemangiopericytoma. The mean follow-up was 19 months (range 13–84 months). Two patients experienced transient diabetes insipidus (DI) requiring desmopressin, which resolved before hospital discharge. One patient (with chordoma) developed delayed permanent DI, and a second patient (with hemangiopericytoma) developed permanent DI and panhypopituitarism. The access angle was higher in the group with pituitary dysfunction (47.25° compared to 33.81°; p = 0.07). Posterior pituitary bright spots were preserved in 75% of cases with normal postoperative endocrine function.

CONCLUSIONS

The endoscopic endonasal transcavernous approach to the interpeduncular cistern with pituitary transposition and bilateral sacrifice of the IHAs does not cause pituitary dysfunction in a majority of patients. When endocrine deficit occurs, it appears to be more likely to have been caused by surgical manipulation than loss of blood supply. This finding confirms clinically the crucial concept of interarterial anastomosis of pituitary vasculature proposed by anatomists.
Biologically-Derived Nanomaterials for Targeted Therapeutic Delivery to the Brain
Authors: Curley Stephanie M. , Cady Nathaniel C.
Published: August 2018

Delivery of imaging agents and pharmaceutical payloads to the central nervous system (CNS) is essential for efficient diagnosis and treatment of brain diseases. However, therapeutic delivery is often restricted by the blood-brain barrier (BBB), which prevents transport of clinical compounds to their region of interest. This review discusses the methods that have been used to avoid or overcome this barrier, presenting the use of biologically-derived nanomaterial systems as an efficient strategy for the diagnosis and treatment of CNS diseases. Biological nanomaterials have many advantages over synthetic systems, including being biodegradable, biocompatible, easily surface functionalised for conjugation of targeting moieties, and are often able to self-assemble. These abilities are discussed in relation to various systems, including liposomes, dendrimers, and viral nanoparticles.

One of the areas that often become a source of traffic jam is road intersection. So it will be crucial to manage the intersection. Every intersection in main road is common to have traffic light and every cycle of the lamp, red, green and orange, will influence the traffic. The traffic cycle will have significant role to decrease or increase effects of the problem. Inappropriate regulation for the intersection can cause traffic jam or a heavy traffic jam in the road. Sometimes every intersection needs different rule based on the traffic condition. Therefore is truly needed to manage the traffic light in every intersection. With the simulation we can know whether the rule for the traffic light has appropriated to the intersection's traffic condition. If the rule is not optimal yet, we can change the rule with the optimal one. In the research, two methods are used, using coupling parameter and without coupling parameter. Average of vehicle Arrival in each intersection is used as coupling parameter. As its result, using coupling parameter is better than without using coupling parameter.

The depletion of fossil fuel reserves and natural gas makes people rethink to find alternative energy substitutes. Biomass is an alternative energy that is still abundant and has not been fully utilized. Gasification is one of alternative in gas making that change from solid fuel (wood powder) to thermochemical flammable gas. The research used downdraft gasification with experimental wood powder. The implementation of research was done in workshop of Indramayu State of Polytechnic, using batch system, it means once the import of biomass in the furnace from the beginning until the biomass out by 5 kg of wood powder biomass. Equivalence Ratio (ER) performed 4 variations namely: 1.01; 1.13; 1.34; 1.52. The recorded data are: temperature inside reactor, gasification operation time, air intake, syngas content, and flame visualization. The results obtained from the gasification process showed if the Equivalence Ratio (ER) is higher so the heating value of syngas decrease. LHV at ER 1.52 of 3980,306 Kj / m3 and the synthetis gas content decreased as much as 21,7806 %

Metal casting is a part of the manufacturing process to produce products that generally have intricate shapes or materials that can not be processed by ordinary machining. The complexity of the product can be achieved with the use of sand molds and the use of cores that are also made of sand. The process of recycling sand can be done by mechanical, thermal and chemical recycling methods. The sand system that has been used to produce waste in the form of waste sand, dust and other contaminants. This waste can be used for several purposes, among others: reused as metal casting sand, road construction, brick material etc. So far, recycling has been done on large scale metal casting. For medium and small scale this is not done. Used sand is treated as waste that is discarded and not utilized. The manufacture of a sand recycling system for metal casting allows the reuse of waste sand for print sand with the technical properties of sand that meet the desired quality. It will also be able to reduce waste disposed by metal casting. The study began with a literature study to find out the characteristics of used sand. Next is to plan the recycling process of the former sand, which then continued with manual sand recycling experiment. Against the recycled sand is then tested to determine its properties. The results of recycling experiments and test results are then analyzed to serve as a basis for designing and manufacturing sand recycling machines for small scale metal casting. The type of sand to be recycled is the CO2 process sand with a base of quartz sand. Based on the research that has been done, the following conclusions are obtained: CO2 process recycling sand technology produced is in the form of recycling system and analysis / study on the quality of recycling; design prototype sand recycling machine CO2 process produced is a design engine jaw crusher and hammer mill machine design.
