Preregistration in experimental linguistics: Applications, challenges, and limitations
Authors: Roettger Timo Benjamin
Published: August 2019

Our current publication system neither incentivizes publishing null results nor direct replication attempts, which biases the scientific record toward novel findings that appear to support presented hypotheses (referred to as “publication bias”). Moreover, flexibility in data collection, measurement, and analysis (referred to as “researcher degrees of freedom”) can lead to overconfident beliefs in the robustness of a statistical relationship. One way to systematically decrease publication bias and researcher degrees of freedom is preregistration. A preregistration is a time-stamped document that specifies how data is to be collected, measured, and analyzed prior to data collection. While preregistration is a powerful tool to reduce bias, it comes with certain challenges and limitations which have to be evaluated for each scientific discipline individually. This paper discusses applications, challenges and limitations of preregistration for experimental linguistic research.

Authors: Noori Hamzah Mohsin , Abdulhessen Gatta Abdurrahman
Published: August 2019

Dorsiflexion and plantarflexion are an important dynamic function by which the ankle-foot prosthesis must simulate the human foot. Dorsiflexion and plantarflexion are essential functions to the walking pattern. However, most ankle-feet prostheses have a notice lack in mimicking the normal gait dorsiflexion and plantarflexion functions. A new carbon fiber ankle-foot prosthesis has been designed and manufactured. Dorsiflexion and plantarflexion tests achieved using a 25 KN tensile test device. The tests have been simulated and analyzed using ANSYS l6 and the results compared with the experimental results. Both test approaches pointed that the new prosthesis satisfy the ISO 10328 requirements that can be classified as multiaxial as it flexed 10oand 8oin dorsiflexion and plantarflexion respectively, under testing loading less than 1230 N.

Authors: A.Essi Noura , M. Hunnun Rafid , I. Radhi Hazim
Published: August 2019

In this paper, two types of stresses acting on the single rotor blade of low pressure steam turbine for Nasiriya power plant were studied. The first type of stresses  was the stresses due to pressure force on the single rotor blade,  while the second type of stresses  are the centrifugal stresses. The stresses due the pressure force were studied in this paper at three loads (70, 140, 210 MW),  while the pressures acting on the first rotor blade of steam turbine  were 512, 3311.7, 6496.8 Pa respectively .  In addition , the blade was fixed at the root and free at the end, while the rotational speed of blade was 341 rad/sec was applied as rotational load.  The results showed that the rotational load has the greatest effect on the blade. Also the stresses due to rotational load are higher than stresses due to steam pressure at the three loads.

DLUWANG SEJARAHMU KINI
Authors: Lestari Ema Puji
Published: August 2019

Papyrus is known as a plant that was used for paper making materials in ancient Egypt. In Indonesia itself there is a traditional paper called paper dluang / daluwang which is used as a medium for writing manuscripts. In the past dluwang tree bark was not only used as paper making but also used as material for making clothes, ropes and crafts. To make this dluwang paper requires a long time and extraordinary patience. Unfortunately, the tradition of dluwang paper making in Indonesia has been extinct since 1960. So the people today do not know what dluwang is. The extinction of the dluwang paper-making tradition was eroded by the modern paper production we know today. That is because the manufacturing process is very traditional so it is felt to be less practical and economical. The dluwang paper making material is a type of plant called the glugu tree (Papermulberry ‘Broussonetia papyryfea Vent’), similar to the murbey / mulberry tree and the hibiscus or saeh (sunda) tree - the bark used for papermaking. In terms of quality, this dluwang paper has very good durability due to its very strong fiber. This is evident from several ancient manuscripts that are still durable today. One of the regions in Indonesia which is famous for dluwang paper production is Tegalsari village, Kec. Jetis, Kab. Ponorogo. Unfortunately dluwang tree cultivation has been threatened with extinction along with the extinction of this dluwang papermaking tradition. There are at least three locations in Indonesia that are currently trying to preserve dluwang paper making namely, Tegalsari Ponorogo, Toekang Saeh Studio, Bandung West Java, and Sekar Jagad Studio, Sukoharjo. The purpose of this study is to identify the use of dluwang as a written media and to reconstruct how the dluwang paper production process is in tegalsari, jetis ponorogo. While the research method used is to use literature studies, interviews and surveys.
The Black Sea in Ptolemy’s Geography: from measuring latitudes and distances to creating a map
Authors: Shcheglov D. A.
Published: August 2019

The configuration of the Black Sea in Ptolemy’s Geography is compared with the information of other ancient geographers. It is demonstrated that their data on the length of the coastlines between the key points match with high accuracy, implying that they drew on similar sources. A possible explanation of numerous disagreements between their data on distances between neighbouring coastal points is suggested. It is shown that the shortening of the west coast of the Black Sea in Ptolemy’s Geography relative to the reports of other geographers was due to his erroneous value of the circumference of the Earth. In general, Ptolemy’s configuration of the Black Sea is explained as a result of merging together contradictory information on the length of coastlines and the latitudes of the key points provided by his sources. These findings contribute to a better understanding of Ptolemy’s method of map-making.
On the efficiency of natural agro-potentsial use in the steppe regions of European Russia
Authors: Chibilev A. A. , Sokolov A. A. , Rudneva O. S.
Published: August 2019

Main aspects of optimizing the use of natural agro-potential of the steppe zone of European Russia are considered taking into account the available natural and socio-economic resources. The study was carried out by comparing the actual and biopotential yield of grain crops as key agricultural crops of the European Russia’s steppe zone. About half of the Russian grain harvest takes place in this area. Areas with different efficiency of agro-potentsial use were identified using the method of spatial expert assessments. The first group includes areas with optimal efficiency of agricultural land use, where the actual yield is close to biopotential. In the second group there are areas with average efficiency, the actual yield is more than 75% of the biopotential. The third group includes areas with low efficiency. The actual yield is less biopotential in this area. Most of the territory of the European Russia’s steppe zone is characterized by low efficiency of agricultural environmental management. There are significant areas of productive arable land, the biological potential of which is not used rationally due to organizational and economic difficulties. The current level of management does not reveal the potential of cultivated soils in each region. Methods and culture of agriculture may differ significantly within the same farm, which leads to variations in actual yields, while reserves increase the actual yield can be up to 50% of its current level. In turn, the identified features can serve as the basis for the development of geographically differentiated programs of rural areas’ integrated development in the steppe zone of European Russia.
Structure of large flat-bottom depressions on loess interfluves of eastern Azov region (on the example of “Chervonaya Pad'”)
Authors: Zakharov A. L. , Konstantinov E. A.
Published: August 2019

Geological and geomorphological structure of the “Chervonaya Pad’”, one of the largest orientated depressions of Eastern Azov region, was considered. The study is based on the results of the analysis of remote-sensing data and new geological data obtained during manual drilling and studying the coastal outcrops. Features of the morphological similarity between the neighboring large depressions and “Chervonaya Pad’” was revealed. It is evidence of the unity of their origin. This allows us to consider “Chervonaya Pad’” as a model object for research. The features of the geological structure and morphology of the “Chervonaya Pad’” show that the depression is a denudation form developed in the cover of loess deposits as a result of the impact of airflow on the surface. According to the paleosol stratigraphy, it was revealed that the main stage of the formation of the depression was in the end of the Middle Pleistocene.Based on the material obtained, the authors verify the existing hypotheses of the formation of the large flat-bottom depression relief of the Eastern Azov region. It is revealed that the previously proposed mechanisms for the formation of large depressions (thermokarst, erosion-suffusion, loess subsidence, estuary-lake) do not consistent with the actual data on the geological-geomorphological structure of the “Chervonaya Pad’”. The authors propose the hypothesis of the eolian-denudation (deflation) origin of large depressions of the Eastern Azov region.

The National Park “Valdayskiy” (the Park) was established to preserve the unique lake-forest complex of the Valday upland and to create conditions for the development of organized recreation on this territory. Incomparable beautiful views of different landscapes attracthere thousands of tourists from various Russian regions.The greater number of them prefers lakeshores for camping,so special attention in the research was paid tothe studyofriparian and shallow water vegetation of lakesin zones with different recreation pressureto establish the patterns of vegetation digression.The materials of our observations are supplemented with data on the attendance of tourist sites collected by the Park staff.The region recreation capacities were studied on the base of bioclimatic indices (Bodman’s indices and subjective temperature).It was revealed that only for the period of 1 month (mid-July to mid-August), there is a massive influx of tourists and intensive use of recreation sites on the lakeshores.This leads to degradation of riparian forest and meadow vegetation; destruction of the protective (buffer) zone of aquatic vegetation, erosion of the banks near camps, pollution of shallow water by sewage and garbage. Thus, irregular recreation pressure on water bodies leads to local degradation of natural complexes and eventually to lowering the aesthetic value of riparian landscapes. But such factors as humid (moderate) continental climate with a prolonged cold winter and high relative air humidity throughout the year reduce the period of a strong recreation pressure, and the complicated accessibility of many lakeshores reduce the negative impact of recreation and delay the destruction of natural vegetation. Evaluation of the bioclimatic indices allows Valday to be attributed to regions with a lack of thermal resources, it is preferable to develop here dynamic types of recreation activities practically all over the year. For soft recreation activity the Valday upland are available with limitation from 7 to 8 months in a year and without limitation nearly 1 month in a year. For nature conservation in the Park it is necessary to organize monitoring of lakeshore’s complexes, control of recreation use, determine pressure of tourist traffic, normalizing and differentiating this pressure by the types of possible use and conservation regime.

‘TAM 204’ (Reg. no. CV‐1155, PI 686859), a hard red winter wheat (Triticum aestivum L.) cultivar with the experimental designation of TX06V7266, was developed and released by Texas A&M AgriLife Research in 2014. TAM 204 is an F4–derived line from the cross ‘TAM 112’/TX01M5009 made at Vernon, TX, in 2001. TAM 204 is an apically awnletted, medium‐maturing, semidwarf wheat with red glumes. It was released primarily as a grain, dual‐purpose, and graze‐out wheat with high grain and forage yield potential. It has good acid soil tolerance, is resistant to Soil‐borne wheat mosaic virus, Wheat streak mosaic virus and its vector wheat curl mite, greenbug, stem rust and stripe rust, and it is moderately susceptible to leaf rust. TAM 204 has a high level of resistance to Hessian fly biotypes GP and vH9 and a moderate level of resistance to biotype vH13. Compared with ‘TAM 111’, which is currently the most widely grown cultivars in Texas, TAM 204 has significantly higher grain yield in the Texas High Plains under both irrigated and dryland environments. Compared with ‘TAM 401’ and ‘Weathermaster 135’, which are currently the two most popular apically awnletted cultivars in Texas, TAM 204 has similar forage yield but higher grain yield across a wide range of environments. TAM 204 could be a better option for wheat growers and cattle owners under grain‐only, dual‐purpose (grazing‐plus‐grain), and graze‐out production system in the southern US Great Plains.

Published: August 2019

In this
research a novel preform for the reinforcement of tubular composite structures
has been developed. The mentioned preform was woven from para aramid yarn in
the tubular form. A mandrel was passed through a certain amount of tubular
woven preform layer then impregnated with resin, cured in an oven and the
resulting composite pipe was removed from the mandrel. By using the same para
aramid yarn, filament wound composite pipes were also manufactured with the
same production parameters. Axial and transverse compression behaviors of
tubular woven preform reinforced composite pipes were compared with the ones
that are manufactured by conventional filament winding method. The test results
indicated that under transverse and axial compression, composite pipes
developed in this study showed superior strength values than filament wound

Silk cultivation in the upstream aspect produces products in the form of cocoons or silk fiber. The production of silkworm cocoon farmers is highly influenced by many factors, including weather, availability of silkworm feed, quality silkworm seedlings, labor and cultivation space that meet the ability to produce an optimal cocoon. The variety of supporting factors has an impact on income uncertainty in meeting household needs so that a strategy is needed to fulfill life needs. This paper aims to provide information on the strategies for the livelihoods of silk farmers in fulfilling life needs that are useful in policy making for natural female development. The research was conducted in Sering Village, Donri-Donri Sub-District, Soppeng District, South Sulawesi Province. Observations and interviews were conducted on silk farmers to gather information which was then analyzed descriptively qualitatively. Through interviews, information was obtained that the income of silk farmers came from the sale of cocoons or silk thread. Fulfilling food (staple and water) and non-food needs (energy, water, education, and health) are carried out through on-farm and non-farm strategies and optimizing government assistance. For this reason, community empowerment activities are needed so that the welfare of silk farmers can be improved.

A proposed road project inside a campus that will have to down trees from its mini forest have attracted different public opinion among the faculty and students. In this paper, we would like to justify our view objectively based on transportation engineering point of view. The Ideal Flow Network (IFN) method was used to do the analysis because its source code is publicly available for clarification. The network data is based on previous study of Ateneo Traffic Group report. Two scenarios were set: based scenario that represents the current road network, and two proposed scenario that represents the current road network with additional proposed road in two ways and one way respectively. Analysis of the results show that the total network travel time of the proposed scenario are increased by 4.69% and 2.32% respectively for two ways and one-way scenarios. The network speed will be slightly improved by 0.03% in when the proposed road project is added in two ways. Thus, we failed to justify that the proposed network has better network performance.
