Authors: Omran A , Yahya SHS 
Published: May 2020

AbstractAn Environmental Management System (EMS) was introduced to meet the environmental needs and an organization should have an understanding of what those environmental needs are. In a construction industry, the awareness about the environment performance is improving and the need to protect the environment quality is growing good in order to maintain the sustainability of the development in a country.Spirit of sustainable development embodied and endorsed in the medium- and long-term development strategies such as Third Malaysian Plan (1976-1980) and thereafter, e.g. Seventh Malaysian Plan (1996-2000). Thus, the construction players that involved in the construction projects have to take the responsibility to accept all the regulation related to the environment protection during construction processes. This study concluded that the awareness of EMS among the construction players in Kelantan State is very low. Most of the construction players understand an EMS. However, although they understood what EMS is, yet they did not implement and apply the system within the construction sites. They understand an EMS and its obligation, but some of them, indicated that it is not important to be implemented, as they are doing projects just to get the profit. Although, the construction players understand an EMS, but they do not have any skills and experiences in implementing EMS within construction site.

Abstract
Nowadays, learning about automation technology in higher education is important to produce graduates who are ready to work. However, in developing countries, this learning is often constrained by the problem of limited costs and places to procure practice tools. To overcome this problem, this research focuses on developing automation technology learning tools that are inexpensive and less space. The object is Automated Storage and Retrieval System (AS / RS) which is commonly used in various industries for material handling but is too expensive and large for learning. The AS / RS developed is an Arduino based AS / RS with multi-input modes that are pendant, coordinate, and RFID. The AS / RS is designed to facilitate students to learn the work system, electrical circuit, and programming algorithm. The research was held in several stages: problem identification, electrical hardware design, mechanical design, algorithm and programming design, prototyping and testing. The AS / RS prototype only costs $ 230 and requires 600 x 400 x 550 mm space. The testing was carried out on functionality, usability, and educational ability using task completion and essay post-test method. Based on the test, the three aspects of the designed AS / RS were very satisfying.

Abstract
Indonesia which consists of many islands has difficulty in establishing national distribution logistics. Because of the sea traffic expansion in Eastern part of Indonesia, the existing port is limited and cannot handle such a problem. To accommodate this problem, new port is built in Surabaya, East Java, Indonesia. However, the new port usually faces to handle an unlimited demand with limited resources. This paper evaluates the port productivity of container loading and unloading activities. Equipments used in container loading and unloading at this port include cranes and other equipments. Because of many complexities in the observed system, discrete event simulation is used to evaluate the terminal operation performance. The simulation results show that STS crane quantities and formations for loading and unloading activities are affecting the new port productivity.

Published: May 2020

Abstract
Workload experienced during certain work periods may cause fatigue. In Air Traffic Control work, a high air traffic rate may increase the workload and fatigue, especially during rush hour and may lead to risky situations. This study intended to estimate the value of the mental workload and fatigue of an Air Traffic Controller (ATCo) in airport X during their work period. The NASA-TLX and Samn Perelli Scale were used to quantify mental workload and fatigue. The questionnaires were distributed to ATCo and 257 questionnaires were obtained. Results showed the value of the mental load at airport X tended to be higher than other airports (average 66.53), especially for mental demand, time pressure, and effort. The value of fatigue before and after work also increased (average 1, 749 to 3, 506) included in the safe category. However, there was no convincing evidence that differences in mental load values affect the value of fatigue. These results indicated that although the workload of ATCO was relatively high, the ATCo in Airport X still can handle it and did not cause excessive fatigue.

Abstract
Nanoparticles from chitosan and hyaluronic acid were obtained using ionotropic gelation technology. The size of the nanoparticles was investigated using electron microscopy and dynamic light scattering. Nanoparticles were obtained of an optimal size of ∼ 100 nm. A physical association method has been developed of encapsulating nanoparticles with doxorubicin, a well-known antitumor drug, and dinitrosyl iron complex (donor of nitric oxide). The surface potential of nanoparticles was determined by dynamic light scattering. It was shown that HA-DOX: CS {6: 1} nanoparticles were stable and had a potential of -45.6 meV. The localization of nanoparticles in the cancer cells has been studied by confocal and FLIM microscopy. It was found that nanoparticles with doxorubicin are located in the cell near and inside the nucleus. It was shown that the encapsulation of DNIC in the composition of nanoparticles significantly increases the stability of DNIC, prolongs the formation and increases the yield of nitric oxide. A unique nano-system has been created for the delivery of anticancer drugs into the cell.

Annotation
In this work, novel nanostructured organosilicon luminophore (NOL) containing four 2, 2’-bithienyl donor units connected via silicon atoms to 4, 7-diphenyl-2, 1, 3-benzothiadiazole acceptor unit was synthesized. Photophysical measurements of the NOL revealed the effect of solvents polarity on its photoluminescence quantum yield (PLQY). In THF solution the efficiency of photoluminescence was only 4%, whereas in toluene solution PLQY increased up to 76% without any changing the spectral characteristics. Under the normal conditions, the NOL synthesized is a viscous fluid, which contributes to its good solubility in various solvents. The NOL is thermostable up to 415 °C in argon atmosphere.
New method of obtaining heat-resistant biomorphic composites with carbide reinforcement
Authors: Ershov A E , Prokhorov D V , Stroganova T S , Shmytko I M 
Published: May 2020

Abstract
In this work, an original method of obtaining biomorphic composites of the Me – MeCx type, consisting of several stages, has been proposed. One of the steps is the Infiltration through Nonreactive Solvent (INS) method, which consists in converting biomorphic carbon preforms into porous microchannel MeCx ceramics by transferring a carbide-forming element to carbon through a solvent that does not react with carbon. The interaction of biomorphic alder-based carbon templates with melts of Cu – Ti and Sn – Ti systems has been investigated. It has been shown that as a result of the interaction of biocarbon templates with Cu-10Ti and Cu-20Ti alloys, carbon walls turn into TiC grains of micron and nanometer sizes, which partially repeat the template microstructure. The mechanism of formation of such a structure has been proposed. It has been demonstrated that, upon the interaction with Sn – Ti system, TiC and Ti2SnC layers are formed on the surface of the microchannels with good preservation of the initial template structure.

Abstract
The conditions for obtaining stable aqueous solutions of prospective pharmaceutical: a lipophilic aminonitroxyl platinum complex, namely, e-amine-d-(4-amino-2, 2, 6, 6-tetramethylpiperidine 1-oxyl)-a, fbis(octanoato)-b, c-dichloroplatinum(IV) (PNC), and a dye zinc tetraphenylporphyrinate (ZnTPP) by means of their solubilization with polymer particles of N-vinylpyrrolidone with dimethacrylate. Aqueous solutions of PNC and ZnTPP encapsulated into polymer particles were investigated by dynamic light scattering, and the temperature dependence of nanostructure sizes was studied. According to transmission electron microscopy, the hybrid nanostructures are core—shell particles, in which the PtIV complex forms small clusters (∼4 nm). It was established by ESR and voltammetric measurements that the free radical fragment of the aminonitroxyl PtIV complex kept its mobility and the same ESR and redox characteristics as the 4-acetylamino-2, 2, 6, 6-tetramethylpiperidine 1-oxyl radical. The obtained results indicate that biocompatible copolymers of N-vinylpyrrolidone are of interests as carriers and delivery tools for ZnTPP and organic PtIV complexes. Hybrid structures of given dimensions and properties can be created on their basis necessary for biomedical applications.
