Here, we describe a new species of the genus Hynobius from Chugoku, Japan. In populations from central to eastern Shimane Prefecture, the Izumo Lineage of Hynobius utsunomiyaorum was clearly distinguished from the true Hynobius utsunomiyaorum based on morphological and molecular evidence. Thus, we describe the former lineage as a new species, Hynobius kunibiki sp. nov. Morphological comparisons revealed that H. utsunomiyaorum lacks a distinct yellow line on the ventral side of its tail, whereas the new species possesses this yellow line; most H. utsunomiyaorum individuals have distinct white spots on the lateral sides of their body and lack a fifth toe, whereas the new species largely lacks these spots, and all examined individuals had a fifth toe. The two species also differed significantly by several other morphological characteristics. The lentic species Hynobius setoi is morphologically similar to H. kunibiki sp. nov., but they differ significantly by various morphological characteristics. Despite their partial morphological similarity, these two species differed substantially in terms of their genetics. Finally, we show, in a phylogenetic tree including all Japanese Hynobius species, that the subgenus Hynobius can be divided into four genetic clades. Overall, this information will help develop conservation management strategies and policies for these species.

Abstract: Special Purpose Forest Region (SPFR) Sisimeni Sanam is one of the area that often forest fire every year. Fires that often occur are from July to November because this month is a dry month. By knowing the factors of forest fires, we can control them. Therefore, what can be done is by controlling the fuel which can be done by isolating the fuel, namely the fire break. This study aims to determine howto manage fuel  through the firebreak method at the SPFR Sisimeni Sanam. Methods of data collection using direct interview techniques, field documentation and library literature.  The results showed that the fuel management at SPFR Sisimeni Sanam used the yellow line manual firebreak method with a distance of 3 meters in each sample plots. This has not been effectively implemented in KHDTK Sisimeni Sanam because the fires in this area were mostly due to spot fire.

We describe a new species of polyclad flatworm, Pericelis flavomarginata sp. nov., from the intertidal and subtidal zones along localities on the Pacific coast of Japan. Pericelis flavomarginata sp. nov. is characterized by i) the dorsal surface of the body fringed by a lemon-yellow line except for the tip of tentacles, with a narrow brown midline running from the anterior edge of the body to the posterior end of the pharynx, ii) the pair of marginal tentacles with the tips extending and tapering, and iii) the presence of a common gonopore. Our molecular phylogenetic analysis revealed that selected Pericelis species were divided into two clades, each of which may be agreed with a characteristic dorsal color pattern. Additionally, we report an observation on the feeding behavior of P. flavomarginata sp. nov. on the polychaete Iphione muricata (Savigny in Lamarck, 1818).

Fuji apples (Malus Domestika) are fruits that contain a lot of antioxidants. Besides the fruit flesh, the apple also contains pectin. Fuji apples are red and have a yellow line. The size of apples can affect the selling price of apples, the determination of the size of apples can be seen from the size of the diameter, measuring the diameter of apples is usually done visually by comparing apples. Based on these problems, a research is needed to develop a system to determine the diameter of fuji apples by using image processing techniques to find the diameter. This measurement process uses the matlab application and tests with the sobel edge detection method and image processing to see the more visible edges of the lines. The results showed that the developed system was able to obtain images and identify the diameter of fuji apples

Under specular reflection, non-isotropic halftones such as line halftones printed on an ink-receiving plastic layer superposed with a metallic layer change their colors upon in-plane rotation of the print. This color change is due to the orientation-dependent optical dot gain of the halftone. A strong dot gain occurs when the incident light is perpendicular to the halftone line structure. A color prediction model is proposed which predicts under specular reflection the color of cyan, magenta and yellow line halftones as a function of the azimuthal rotation angle, the incident angle and the line frequency. The model is calibrated by measuring 17 reflectances at the (25° : 25°) measurement geometry, with the incident light parallel to the halftone lines. The model has been tested for several azimuthal rotation and incident viewing angles, each time for 125 different cyan, magenta and yellow ink surface coverages. The obtained prediction accuracies are between ΔE94 = 3.5 and ΔE94 = 7.

The limited ground marshall, yellow line and others at an airport will affect when parking aircraft. Aviation technology has provided solutions, among others, by attaching to aircraft equipment known as the Visual Docking Guidance System (VDGS), is a tool provided by the airport to help a pilot park his plane without the help of a marshaller to direct the movement of planes to the  correct parking. However, not all airports are equipped with sophisticated equipment. So this research aims to create a system that can make it easier for pilots to park aircraft while in Apron. To overcome this problem, a VDGS tool was designed which was designed using a TF Mini Lidar sensor and programmed for aircraft parking systems at pioneering airports. This tool is able to provide information on the distance of the plane as far as 12 meters given a condition that the aircraft will display identification of guidance or collision prevention that will STOP if the aircraft is at a distance of 1-3 meters, and GO identification if the aircraft is at a distance of 4-12 meters so that this tool can serves as a guide to the position of the aircraft when parking right in the designated parking area and prevent aircraft crashes when parking when entering the apron area at the pioneer airport.

<p>This paper aims to present the construction techniques and development of first and unique monorail system in Bangkok, Thailand. Bangkok is the capital and most populous city of Thailand. The city occupies 1,568.7 km<span>2</span> and has a population of over eight million, or 12.6 percent of the country's population. In the last decade, Bangkok has attracted millions of migrants seeking economic opportunity and city is expanding quickly. Recently, Mass Rapid Transit Authority (MRTA) Thailand has decided to adopt monorail system in Bangkok as a rapid transit system due to the limited space, narrow roads and sharp curves in the city. The design of monorail track lines permits flexible and various alignments that include curves of small radiuses and large slopes. The first two projects i.e., Pink Line and Yellow Line projects consist of elevated structure around 64.9 km long, 53 stations, 2 depots and 2 park-and-ride buildings. MRTA has awarded these projects (design, test run and construction of first two lines) to the BSR Joint Venture who invited Sino-Thai Engineering &amp;</p>

Purpose Travel time is considered as the wastage of time, but the ubiquitous nature of mobile devices with Internet has made it possible to use the time for productive activities. This paper aims to focus primarily on the use of mobile devices while travelling in Metrorail and how travel time is being used “productively” as study time and what resources are the students accessing from their mobile devices. In total, 820 students from different colleges in Delhi were randomly chosen for the survey. Using the survey method, the paper explores how students use travel time productively as activity time. The study revealed that browsing internet, communication, text messaging, accessing social media, etc., are the frequent activities by students while travelling. Majority of respondents stated that their travel time is never productive for value of time. Thinking on different issues that occupy their mind is the most frequent personal activity. “Poor Wi-Fi” connectivity is the highly rated impediment faced by students for uses of mobile devices. Design/methodology/approach A survey was administered to students of different colleges in Delhi who commute daily and consume information while commuting to colleges and back in the month of November and December 2017. The Yellow line that connects most of the colleges of Delhi University was boarded during early and evening hours; a questionnaire was handed out and collected back during the travel. Moreover, a visit was made to different colleges and universities of Delhi. Of the 1,000 questionnaires, only 820 were returned (a response rate of 82%); so a good number of student commuters’ population of Delhi was sampled. Findings The study found that majority of the students that responded to the survey use smartphones while travelling. The study indicated that many students face different impediments in consuming the information of their need. Originality/value The paper provides insight of how travel time is used by the students in Delhi Metro and what activities they do on their miniature devices to make their travel time productive. The study will serve as a template for policy makers and information service providers to realize the need of the hour.
