Authors: Simatupang Defri Elias
Published: January 2020

AbstractThis article initiated from a review made by the Archaeological Office on the discovery of Pangulubalang statue in Simalungun Regency, North Sumatra Province. It was such an urgent review due to the salvation of the statue from the destructive intent by the inheriting society. In the face of imminent vertical conflict, the research team head for home to consult the head of the archaeological office for strategic measures. The incident drove a conduct of a review on the urgency of an effective communication when the government apparatus attempts to save the suspected cultural heritage object while avoiding potential vertical conflict. Inductive reasoning used in this article commenced from the discussions of every data from which a general conclusion will be drawn. The collected data will be analyzed and interpreted as an offered solution model for a salvation policy of the cultural heritage suspected object such as the Pangulubalang statue in Simalungun Regency.AbstrakTulisan ini berawal dari peninjauan Balai Arkeologi Medan terhadap temuan berupa patung pangulubalang di Kabupaten Simalungun, Provinsi Sumatera Utara.

The paper presents the results of high-precision magnetic surveys by a quantum magnetometer using an unmanned aerial vehicle (UAV). The object of research was an area of 10 hectares (500 × 200 m) at the archaeological site of New Kurya in Western Siberia. The accuracy of the registration of the induction module of the geomagnetic field was not lower than 0.3 nT. The spatial accuracy of GPS coordinates lies in the submeter range. Magnetic anomalies caused by ancient mounds with an amplitude of up to 5–10 nT were revealed. The technique for isolating such low-amplitude anomalies included taking into account the geomagnetic variations of the external field, the regional anomalous field, and the use of a number of algorithms for the statistical processing of primary data. Identified magnetic anomalies can reliably determine the features of the device and the size of the mounds, including those not expressed in relief. The information received makes it possible to plan a strategy for archaeological study of this monument at a qualitatively different level. The prospects of further development and use of the technology in question for solving archaeological problems are noted.

Tuning the Redox Activity of Metal−Organic Frameworks for Enhanced, Selective O2 Binding: Design Rules and Ambient Temperature O2 Chemisorption in a Cobalt−Triazolate Framework

Published: January 2020

Metal−organic frameworks (MOFs) with coordinatively unsaturated metal sites are appealing as adsorbent materials due to their tunable functionality and ability to selectively bind small molecules. Through the use of computational screening methods based on periodic density functional theory, we investigate O2 and N2 adsorption at the coordinatively unsaturated metal sites of several MOF families. A variety of design handles are identified that can be used to modify the redox activity of the metal centers, including changing the functionalization of the linkers (replacing oxido donors with sulfido donors), anion exchange of bridging ligands (considering μ-Br-, μ-Cl-, μ-F-, μ-SH-, or μ-OH- groups), and altering the formal oxidation state of the metal. As a result, we show that it is possible to tune the O2 affinity at the open metal sites of MOFs for applications involving the strong and/or selective binding of O2. In contrast with O2 adsorption, N2 adsorption at open metal sites is predicted to be relatively weak across the MOF dataset, with the exception of MOFs containing synthetically elusive V2+ open metal sites. As one example from the screening study, we predicted that exchanging the μ-Cl- ligands of M2Cl2(BBTA) (H2BBTA = 1H,5H-benzo(1,2-d:4,5-d′)bistriazole) with μ-OH- groups would significantly enhance the strength of O2 adsorption at the open metal sites without a corresponding increase in the N2 affinity. Experimental investigation of Co2Cl2(BBTA) and Co2(OH)2(BBTA) confirms that the former exhibits weak physisorption of both N2 and O2, whereas the latter is capable of chemisorbing O2 at room temperature in a highly selective manner. The O2 chemisorption behavior is attributed to the greater electron-donating character of the μ-OH- ligands and the presence of H-bonding interactions between the μ-OH- bridging ligands and the reduced O2 adsorbate.

Published: January 2020

Flexible, small and strong alkyl ligations created upon external light stimuli can open new avenues for medicinal and biological research. Herein, we have found that NADH and analogues can drive photo-couplings without auxiliary photocatalysts. The time- resolved alkyl photo-ligation between redox-active carboxylate derivatives and electron-poor olefins displays a surprising moisture and air-tolerance, and unusually high coupling rates in dilute conditions. This work sets the conceptual basis for further biocompatible C-C coupling reactions promoted by visible-light in combination with NADH, the ubiquitous reductant of biological systems.
Catalytic Hydroetherification of Unactivated Alkenes Enabled by Proton-Coupled Electron Transfer
Authors: Tsui Elaine , Metrano Anthony J. , Tsuchiya Yuto , Knowles Robert
Published: January 2020

We report a light-driven, catalytic protocol for the intramolecular hydroetherification of unactivated alkenols to furnish cyclic ether products. These reactions occur under visible light irradiation in the presence of an Ir(III)-based photosensitizer, a Brønsted base catalyst, and a hydrogen atom transfer co-catalyst. Reactive alkoxy radicals are proposed as key intermediates that are generated by direct homolytic activation of alcohol O–H bonds through a proton-coupled electron transfer mechanism. This method exhibits a broad substrate scope and high functional group tolerance, and it accommodates a diverse range of alkene substitution patterns. Results demonstrating the extension of this catalytic system to carboetherification reactions are also presented.

This is a study of a medical injection factory-Babylon carried out in order to achieve proper mechanical and morphological properties, PP has been injection molded by using cold runner injection molding machine with temperature variation (198, 200, 203……220°C) for ten samples. The physical and mechanical properties of PP product were examined. It has been found that the Shore hardness decreases linearly with injection molding temperature increasing. The tensile strength has a similar behavior to the hardness. However, it has been found that the MIF (Melt Index Flow) rates increases with the increase of injection molding temperature. The density of PP has been found for both virgin PP and the samples, it has been found that the density decreases with increasing operation temperature. FTIR (Fourier Transmission Infrared) spectra were taken for both samples with high and low operation temperature. Besides the SEM (Scanning Electronic Microscopy) test shows the difference in the morphology of the product surface and the PP product at high and low operation temperature. Moreover, for all these properties, the PP product exhibits good mechanical properties (hardness, tensile strength, density) for the samples produced at temperature lower than 207°C. While the physical properties such as MIF improved with injection temperature increasing, additionally, the SEM images show that the sample produced in low temperature have surface damage.

Authors: Knop Krzysztof
Published: January 2020

The article presents the results regarding the elimination of constraints in the production process of a power equipment subassembly, a boiler chamber, together with an analysis of the benefits resulting from this, both financial and non-financial. The significance of bottlenecks in the production process, ways of its identification and limitations - in general - are presented. The article is a case-study of an attempt to eliminate the bottleneck in the production process of the boiler chamber, which turned out to be the process of drilling and marking-off, and work stations representing these processes. In order to eliminate the limitation, it was decided to replace the existing tracing and drilling work with a numerically controlled device - a boring machine moved from the liquidated department.. As a result, labor-intensive, manual chambers marking-off and the process of drilling holes with a smaller diameter drill have been eliminated. A number of benefits has been demonstrated resulting from the elimination of the bottleneck in the process, first of all, it was possible to reduce the duration of the marking-off and drilling operations and reduce the costs of the boiler chamber production process.

Published: January 2020

The lack of a common methodology on compaction theory stimulates developers of road construction equipment to create various approximate methods for their calculation, the number of which, at the present time, is comparable with the nomenclature of the proposed designs of rollers. The article presents the analysis of the deformable shell behavior of a road roller, and the compacted material under its compacting roller, in a situation when a rigid circular shell of the roller is replaced by a forcefully deformable elliptical shape, which, unlike the circular design, allows variation, adjustment and optimization of the road roller impact on the material to be compacted.

Authors: Popescu Gheorghe Cristian
Published: January 2020

Common Agricultural Policy represents the main instrument of the European Union for the development of agriculture and rural areas. European funds are vital for the productivity and competitiveness of agricultural holdings, as well as for the transfer of agricultural knowledge and innovation. Supporting small and young farms is essential for the vitality of rural areas and for the renewal of generations of farmers. The aim of this work is to transfer agricultural knowledge in order to improve the productivity of agricultural holdings, especially among young farmers and small farms. We implemented training program through European funds related to Measure 1. “Actions for knowledge transfer and information actions” from Rural Development Programme of Romania. The characteristic of 100 participants and their responses were analyzed. Most of the participants were young people up to 40 years old (59%). The vast majority of the participants were from the rural area and only 17% were from the urban area. 53% from participants were strongly agree with the fact that level of knowlegde influence farm productivity. Actions for knowledge transfer improve the adaptation of farmers to the new challenges of agriculture, as well as productivity.
Customer Journey Clue-based Service Failure Prevention
Authors: Labajan Ruth April A. , Koomsap Pisut
Published: January 2020

Customers and their perception towards service are considered as a determinant of service failure, and so, service failure and its prevention must be looked into from the perspective of the customers. This paper presents a customer-centric service failure prevention framework, which aims to provide a holistic way of service failure prevention by integrating service delivery assessment and failure analysis from a customer perspective, encompassing failure identification, assessment and prioritization of failures as a basis for corrective actions. Customer journey, service clues, and customer oriented-FMEA are employed to develop the proposed framework. The approach was applied to an enrolment process showing that using customer journey assists in determining customer processes, needs, wants and touch points in the service, and when used together with service clues further facilitates systematic and effective unveiling of potential failures that are important to customers. Assessment of failures and its prioritization with customer perspective leads to better prioritization that is reflective of the voice of customers. The case study shows that higher risk is imposed by actions emanating from the employees, reinforcing further that service failures not only concern functionality of the service but equally important also are the encounter of customers with service employees and the environment.

A constant increase in the production of plastic products is a major cause of general environmental pollution. The past decade recognized how significant recycling plastic waste and the development of biodegradable materials is. This paper takes a new look at reducing the amount of plastic waste in the environment. Plastic bottles are “dressed” in a special PE (polyethylene) foil before filling. After the content is consumed, the foil is removed of the bottle. Such foil can be used for transporting other products more than once. The work focuses on the investigation of the changes in properties of the light density polyethylene (LDPE) foils caused by forming during their application to the bottle. It was decided that the optimal method for this investigation was to compare the mechanical and rheological properties PE foils before and after their application to the bottle.
The impact of the resolution of the measured object on the assessment of its perimeter

Published: January 2020

Automatic detection of objects is a part of visual systems supporting a quality control system of a manufacturing process. The paper concerns the influence of the resolution of images and the size of detected objects in pixels on measurements results. Test images of the objects of a known size were generated. The values of the perimeter of the objects were compared to the obtained values of measurements on the images with degraded resolution. The process of the degradation of the references images by successive downsizing the resolution, detection and measurements were performed applying automatic algorithm. The analysis of obtained results showed that the size of the analysed objects on the digital images plays an important role in reliability and accuracy of the measurement. The author concludes that, in order to avoid a bias in measurement caused by insufficient object resolution, the minimal acceptable size of objects on digital images in pixels should be recommended.

Published: January 2020

The article deals with a reduction of friction coefficient of bearing steel 100Cr6. Reduction of friction was achieved by means of a CarbonX DLC coating. The coating exhibited excellent friction and mechanical properties. This coating was applied to samples made of 100Cr6 bearing steel. The friction results of the CarbonX coating were compared to the friction results of the 100Cr6 bearing steel. Reducing the friction of 100Cr6 bearing steel resulted in reduced wear and increase lifetime. The friction process of the samples will take place in an environment without lubrication. The aim of the article is to verify the behaviour of the DLC coating without the presence of lubricant in the friction node. The achieved results are to be interpreted in the conclusion of article.

Natural rubber is a strategic natural raw material, which is used in the production of tires and military equipment, in medicine and other industries. An alternative to Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg. and the most promising rubber plant is the Russian dandelion (Taraxacum kok-saghyz Rodin). The rubber that accumulates in the roots of this dandelion is not inferior in quality to the natural rubber from H. brasiliensis, and its content reaches 27% of the dry weight of roots. The purpose of this paper is to describe the economically important components of T. kok-saghyz roots, the main methods for extracting natural rubber from the roots, as well as the approaches to micropropagation and genetic transformation of kok-saghyz and related species. In the middle of the 20th century, the industrial method of isolating rubber from Russian dandelion in the USSR was based on preliminary treatment of the roots with a 2% solution of alkali, which could negatively affect rubber quality. Therefore, it is important to develop new, rapid, but at the same time, inexpensive methods of rubber extraction from T. koksaghyz. Some of them are considered in this paper. The breeding of Russian dandelion should be aimed at both increasing the root size and the content of rubber. In this regard, the development of laboratory express methods for rubber extraction is also important. The authors have developed and optimized a method for extracting rubber from dry plant tissue using polar solvents (water and acetone), with the final extraction with a non‑polar solvent (hexane). The developed rubber extraction protocol showed results comparable to the literature data. In order to create more productive plant forms, experiments are also being conducted on T. kok-saghyz micropropagation and genetic transformation. However, the number of such works is still very small, probably due to the low regenerative abilities of this dandelion species.
