Introduction: Air pollution from industrial sources is a growing problem increasing the amount of air pollution by emitting various gaseous pollutants such as Nitrogen Oxides (NOx). This study analyzed Nitrogen dioxide (NO2) emissions using American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) from the stacks and flares of a gas refinery in the Middle East.
Materials and methods: The NO2 emissions were measured from the stacks and flare of the refinery (231 samples). The distribution of emissions was investigated over a statistical period of 1 year for an average time of 1 h using the AERMOD dispersion model in an area of 25×25 km2. The predicted concentrations were compared with national and international standards and are plotted for the desired zones.
Results: Comparison of simulation results with national and international clean air standards showed that NO2 emission modeled in all periods of 4 seasons is higher than the standard. Examination of NO2 emission and distribution maps also showed that the maximum concentration of NO2 pollutants occurred in the central parts and the area close to the refinery. The highest maximum concentration of 1-h NO2 was 3744.3716 μg/m3 in summer in the west and south of the refinery. Validation results also showed a high correlation between the predicted and actual results.
Conclusion: The power of resources in emission and distribution, topographic conditions, and meteorological characteristics of the region are three important and influential factors in the distribution of NO2 pollutants. So pollution reduction strategies are needed due to the different types of use, surrounding residential areas, personnel, and people involved in the gas refining company.

Zeleni prehod energetike temelji na masovni integraciji obnovljivih in razpršenih virov energije. Zahteve investitorjev po vključevanju novih virov povzročajo težave, ker posamezni elementi omrežja zaradi termičnih omejitev ne dopuščajo dodatnih obremenitev. Zato je pomembno, da obstoječo infrastrukturo čim bolje izkoristimo. To nam omogoča tehnologija dinamičnega ocenjevanja prenosne zmogljivosti, ki temelji na izračunu termične obremenitve gradnikov omrežja. Ta tehnologija se lahko uporabi za daljnovode in za transformatorje. Še posebej zanimiva je indirektna metoda, pri kateri dobimo rezultate brez namestitve senzorjev, le z upoštevanjem vremenskih dejavnikov, ki vplivajo na segrevanje in hlajenje posameznih gradnikov. Slovenski operater prenosnega omrežja Eles je eden prvih operaterjev v Evropi, ki je indirektno metodo za dinamično ocenjevanje prenosnih zmogljivosti začel uporabljati v okviru obratovanja elektroenergetskega sistema. Skupaj s partnerji je razvil SUMO, modularen sistem IT z vsemi potrebnimi funkcionalnostmi. Dosedanje izkušnje kažejo, da sistem omogoča v povprečju od 15 do 20% večjo izkoriščenost daljnovodov od nominalne vrednosti. V članku je SUMO predstavljen z vidika funkcionalnosti in izvedbe. Opisana sta izvedba SUMO na Elesu in projekt uporabe SUMO za transformatorje v distribucijskih omrežjih. Podani so tudi trendi nadaljnjega razvoja, ki so povezani z varnostnimi izzivi ter načrtom, da SUMO postane odprtokodna platforma za povezovanje sistemov IT in OT.

Kaj je Blazor in kako se primerja z JavaScript ogrodji?
Authors: Prtenjak Matjaž
Published: September 2022

Nekako smo se že navadili, da se spletne aplikacije razvijajo v programskem jeziku JavaScript. Tukaj govorim o programski kodi, ki teče v brskalniku, kajti sodobna spletna aplikacija potrebuje tudi zaledje, podatkovne baze in podobno. Vsa ta zaledna koda je pisana v različnih programskih jezikih. Koda, ki teče v brskalniku in torej uporabnik z njo neposredno kontaktira, pa je v večini primerov klasična JavaScript koda. Kaj pa, če bi želeli izdelati spletno aplikacijo v kakšnem drugem programskem jeziku? Kaj pa, če sicer uporabljate Microsoftova razvojna okolja in bi želeli spletno aplikacijo, ki teče v poljubnem brskalniku, napisati v programskem jeziku C#? Leta 2018 je bil sprejet standard poimenovan WebAssembly [1], ki ga podpirajo vsi novejši brskalniki. Kot že ime implicira gre za neke vrste strojni jezik (assembly) brskalnika. In če naredimo prevajalnik za ta strojni jezik, se potem lahko ta koda izvaja v brskalniku. To je Blazor [2] in to je tematika tega prispevka.

Published: September 2022

Bulbar urethral ischemic necrosis (BUIN) is an iatrogenic entity resulting from repeated attempts at performing anastomotic urethroplasty for pelvic fracture urethral injuries. Etiologically speaking, BUIN is related to a compromised blood supply of the bulbar urethra, which normally relies on anterograde supply from bulbar arteries and retrograde supply from recurrent branches of dorsal penile arteries, through the glans. At each transection of the bulbar urethra, both the anterograde and retrograde supplies are compromised, increasing the risk of BUIN. Even though this term is widely used among reconstructive urologists, BUIN is orphan of an accepted scientific definition. We aim to report our personal perspective on BUIN, to identify factors associated with its occurrence, and to describe the management options in these patients.
Performance assessment of pantograph and overhead system based on a vertical coupling dynamics model of the railway system
Authors: Song Yang , Duan Fuchuan
Published: September 2022

The increase of train speed leads to a violent vibration of the pantograph and overhead system. To evaluate the interaction performance of the pantograph and overhead system, a whole railway dynamics model including the track, vehicle, pantograph, and overhead system is established. The overhead system is represented by the finite element approach using the analytical formulas of nonlinear cable and truss elements. The vehicle is modeled by a multi-rigid-body system with a pantograph installed on its roof. A beam element with elastic foundations is used to model the track, which possesses harmonic and random irregularities. An iterative algorithm is implemented to solve the nonlinear behavior of the coupling model. The nonlinearities in the deformation of overhead system, the contact of the pantograph and contact line, and the contact of the vehicle-track are properly considered. Several numerical simulations are implemented to systematically investigate the influence of the vehicle-track vibration on the dynamic behavior of pantograph and overhead system. The results indicate that the vehicle-track vibration induced by the rail irregularities with large amplitude or certain wavelength can significantly aggravate the interaction performance of pantograph and overhead system.
Additive manufacturing as a tool for high-throughput experimentation
Authors: Xiong Wei
Published: September 2022

Additive manufacturing (AM) is a disruptive technology with a unique capability in fabricating parts with complex geometry and fixing broken supply chains. However, many AM techniques are complicated with their processing features due to complex heating and cooling cycles with the melting of feedstock materials. Therefore, it is quite challenging to directly apply the materials design and processing optimization method used for conventional manufacturing to AM techniques. In this viewpoint paper, we discuss some of the ongoing efforts of high-throughput (HT) experimentation, which can be used for materials development and processing design. Particularly, we focus on the beam- and powder-based AM techniques since these methods have demonstrated success in HT experimentation. In addition, we propose new opportunities to apply AM techniques as the materials informatic tools contributing to materials genome.

Payment of the premium which paid with one payment at the beginning of the contract time called as net single premium. One factor that influenced the calculation of life insurance premiums is a life probability. In general, a life probability constructed by the assumption that death only involves two conditions, life and death. Yet, there are another condition for the insured that also affect a person’s death condition which is sick. The objecktive of this research is to determine net single premium of term life insurance formula using transition probability as a life probability. The first will constructed transition from three condition which are health, sick, and death as stochastic process.

The logistic growth model with proportional harvesting is a population growth model that takes into account harvesting factors. In real life, not all conditions can be known with certainty, such as different growth rates in each population and harvest rates depending on the needs of the harvester. To overcome these conditions, there is a concept that accommodates the problem of uncertainty, namely the fuzzy concept. This concept can be induced into a logistic model with proportional harvesting which assumes the intrinsic growth rate and the harvest rate is expressed by fuzzy numbers. The purpose of this research is to form a logistic model with fuzzy proportional harvesting, analyze the stability of the model, and form a numerical simulation. This study uses the alpha-cut method to generalize the intrinsic growth rate and harvest rate from crisp numbers to fuzzy numbers, then the Graded Mean Integration Representation (GMIR) method to defuzzify the model, and the linearization method to analyze the stability of the model. The results of this study obtained a logistic model with proportional harvesting. Then the model was developed into a logistic model with fuzzy proportional harvesting by assuming the intrinsic growth rate and the harvest rate expressed by fuzzy numbers. From the model obtained 2 equilibrium points, namely the first equilibrium point is unstable and the second equilibrium point is asymptotically stable under certain conditions. Model simulation is given to show illustration of stability analysis. From the simulation, it can also be shown that the higher the graded mean value, the lower the population.

Sustainability in managing natural resources depends on the availability of current and future resources within management schemes. Tapping Pine trees for resin production have long been practiced in Bukit Daun Protection Forest, Kepahiang, Bengkulu, despite Bengkulu has not been known as a main province producing pine’s resin. Therefore, it was worthily to examine the sustainability of managing pine stand for production of pine’s resin at Bayung, Seberang Musi, Kepahiang, Bengkulu. The research was carried out with Multi Dimensional Scaling (MDS) approach and using Rapid Appraisal for Tapping Pine Trees (RP-TPT) software. It was constructed by ecologiy, economy, Social and culture, law dan institution, and technology and infrastructure dimensions. Ten attributes were assigned to each dimension. The result indicated that the managing pine stand was moderately sustainable (57.66). All dimensions were categorized into moderately sustainable, except to technology and infrastructure dimension (48.15), which was classified as poorly sustainable. Among 50 attributes, sixteen attributes were grouped as sensitive, meaning they are strongly influential to the sustainability to pine’s resin production. Sustainability could be increased by management intervention, especially to the improvement of tapping’s kill attribute of the technology and infrasrtucture dimension. This management intervention should also be followed by the improvement of the other attributes.

Indonesia with a country that has a tropical climate and a very large intensity of solar radiation so that it can be developed into an alternative energy source by utilizing sea air. The purpose of this research is whether there is an effect of solar radiation on sea air on the power it produces as an alternative energy. Seawater as much as 300ml is put into a square glass container and paired with a series of Cu - Zn, Cu - Al, and Al - CuZn electrode plates with a cross-sectional area of 15cm2 of each electrode and connected to a red LED light to see how much power is generated by sea water after being exposed to solar radiation at different temperatures and times. Data obtained at the highest temperature of 33°C and the duration of exposure to solar radiation for 60 minutes in the 6th experiment with a variation of Cu - Zn electrodes with an electric power of 1,44 J/s, the lights are brightly lit, Cu - Al with electric power of 1,22 J/s of dim light, and Al - CuZn obtained electric power of 0,65 J/s. So it is concluded that the longer the sea water is exposed to solar radiation, the higher the temperature is due to the more heat stored in sea water. The conclusion was drawn that the higher the sea water temperature, the electric power produced, the higher the electric power generated and the lights can light up brightly at certain electrodes.

The development of industry and human living system recently bring effect toward the air quality. Carbon monoxide (CO) which is one of the air pollutant produced by the imperfect ignation which contain carbon of industry, vehicles, and other activities. The existance of carbon monoxide (CO) which is difficult to recognize because of it’s characters which are colourless, cannot be felt or tasteless, cannot be smelt or have no smell, cannot be seen by bare eyes, it means that it needs a tool to help human detect the existance of carbon monoxide. This importance of detector tool of carbon monoxide is because carbon monoxide is quite dangerous for human health if it’s degree is over the limit. There are quite cases of poisoned people who finally died. In this research, the effectiveness test of the use of MQ-7 censor which is integrated with the Blynk application compared with the CO-meter is done. The result shows that MQ-7 is effective to be used in detection and measurement the degree of CO in the air. The integration with Blynk application on the smartphone helps researcher to do the monitoring from everywhere, as long as it is connected to the internet. The price which is more economical also becomes one of the considerations, so CO detector by using MQ-7 censor inegrated with the Blynk application can be done by many groups of society, either industries or individuals.

Mining is a series of activities of exploring, mining (excavation), processing, utilization and marketing of minerals (minerals, coal, geothermal, oil and gas). Gunung Mas Regency, especially Tanjung Riu Village, Kurun Subdistrict, is one of the places in Central Kalimantan Province which has mineral resources including primary and secondary gold, zircon, iron ore and coal. People’s mining activities, especially gold mining in Tanjung Riu Village, are increasingly being carried out by the people and are further away from road access. This causes the people's mining area become increasingly depleted, so that in mining closure, it leaves the formation of critical land that is not organized and is not in accordance with the function of the surrounding environment and cannot be utilized. Most of the critical lands are in the form of void pits have the potential to cause various contimination, such as decreasing the quality of water stored in the voids due to metal contamination and decreasing the pH value of the water so that the water becomes acidic. The description above becomes the basis for research on the design mining closure of people‘s mining area in Tanjung Riu Village, Kurun District, Gunung Mas Regency. This design will be able to make the land useful again both for the People around the research location and for the general public whose use of the ex people’s mining area.

Revegetation can trigger a succession process in post-mining land. The success of revegetation can be assessed by increasing the natural species in the revegetation area. The research objective was to analyze the natural regeneration of mines from several revegetated areas with different planting ages (2 years, 4 years, 6 years, and 8 years). The research was conducted in the post-coal mining revegetation area of PD. Baramarta, Sungai Pinang District, Banjar Regency, South Kalimantan. Data collection was carried out using the nested plot method by making 6 plots measuring 20m x 20m. The data collected were the number of species, the number of individuals and the diameter of poles and trees. Data analysis used tabulated matrices and Importance Value Index. The results showed there were 11 plant species in the revegetation area, 7 natural plant species, 3 main plant species and 1 secondary plant species. Natural vegetation regeneration is only found at the seedling and sapling level. L.indica and C. longifoliium, based on Importance Value Index, are natural vegetation types that dominate the vegetation structure of revegetation areas. Main plant types A.mangium and P. falcataria are able to regenerate naturally. Limited habitat in post-coal mining areas has limited natural regeneration in revegetation areas. Increasing the diversity of revegetation plant vegetation can be done through enrichment planting

Currently, forest and land fires have become a regular disaster in Indonesia. The cause of the fires was mostly due to human factors. Ogan Ilir is an area with forest and land fires every year because its dominated by wetlands. The study aim was to analyze human factors as the cause of land fires in knowledge factors, cultural factors, social factors, economic factors, and policy roles. This study is a descriptive analytic study with a qualitative approach. Data was obtained through interviews with key informants who had been sentenced to be fire perpetrators and regular informants from Regional Disaster Management Agency of Regency and Police in Ogan Ilir. The cause of the community burning the land was due to the low level of community understanding regarding the impact of burning the land with the intention of clearing the land and the presence of sonor culture which the community practiced almost every year on the residual harvest. In addition, there are social conflicts between the community and the surrounding land owners, cost savings in land clearing, and the community continues to burn land even though regulations related to land burning already exist. The main factors that cause people to burn are social and economic factors. It is necessary to enforce laws regarding idle land whose ownership is unclear and the local government can provide borrowing heavy equipment at rental prices that are affordable to the community.
