Influence of a maintenance station on atmosphere state

Problem. Automobile transport has a huge negative influence on the environment, not only during using, but also during its service. Goal: to analyze the influence on the atmosphere of the work of car service stations. Methodology: The calculation of atmospheric emissions during the operation of the main production units was carried out according to the standard method. Gas analysis was carried out using an OKCI-5M-5H gas analyzer. Originality: Calculated amounts of emissions of major pollutants, which are formed during the operation of internal combustion engines and during the operation of the main units of the station, determined the amount of pollution from decentralized space heating. Recommendations for reducing the amount of pollutants and the negative influence of stations on the environment within the city are proposed. Practical value. When liquefied gas is used as a combustible gas, emissions of pollutants into the atmosphere are noticeably reduced both in quantitative terms and in qualitative composition. At the same time, the emissions of methane and sulfur oxides decrease by half. There is a significant decrease in carbon monoxide and nitrogen oxide (II) emissions. Analysis of the data obtained shows that when wood is used as a fuel, there are no emissions of sulfur oxides, but the amount of nitrogen and carbon oxides is higher. Particulate matter emissions are not significantly dependent on the type of fuel. During the operation of the service station, the largest amount of gaseous emissions into the atmosphere occurs in the service box of the internal combustion engine. In general, during the operation of a car service station, a significant amount of harmful substances is not added to the atmosphere.

Pre-design of a commuter transport utilising Voltaic-Joule/Brayton motive power systems

ABSTRACTThis investigation surveyed the potential and established outcomes for future 19-passenger fixed-wing commuter transport aircraft concepts employing battery-based Voltaic-Joule/Brayton motive power systems with no additional electrical energy drawn from generators mechanically coupled to thermal engines. The morphological approach was that of a tri-prop (two on-wing podded turbo-props and one aft-fuselage mounted electric motor configured as a pusher-on-pylon installation). A Battery System-level Gravimetric Specific Energy (referred to as “battery energy density”) of at least 500 Wh/kg yielded 39%, 25% and 10% block fuel reductions for 150-nm (Design Service Goal), 430-nm (85th percentile) and 700-nm (maximum range) stage lengths, respectively. All quoted comparisons are against a suitably projected turbo-prop only year-2030 aircraft. In contrast to the reference Beech 1900D, block fuel reductions of up to 44-49% were predicted, which could facilitate a significantly lower deficit in relation to the Advisory Council for Aviation Research and Innovation in Europe (ACARE) Strategic Research and Innovation Agenda (STRIA) 55% target for year 2030. This investigation also indicated that, in the future, suitably flexible hybrid-electric architectures could be fashioned allowing possibility for the aircraft to complete any required city-pair operations (within the legitimate payload-range working capacity) irrespective of exchangeable batteries being available at a given station. Finally, it was also established, assuming such a tri-prop morphology, Normal conducting machines delivering maximum shaft power output of 1.1 MW would be required.

OTOMATISASI MESIN TETAS TELUR PUYUH UNTUK OPTIMASI PEMBIBITAN, PENINGKATAN PRODUKSI DAN PEMASARAN BAGI PETERNAK PUYUH

AUTOMATION TECHNIQUE MACHINE OF QUAIL EGGS FOR OPTIMIZATION OF BREAKING, IMPROVING PRODUCTION AND MARKETING FOR QUAIL FARMABSTRACT Bogor District has a very large area, so the market share for livestock products is also wide open. In 2015 suppliers of quail farmers there are only 20 breeders with quail population ranges from 10 thousand head (Department of Animal Husbandry & Fishery Bogor District). This is a very good opportunity for quail farmers, but the problems faced by quail farmers turned out to be very complex. Two quail farmers who became the object of Community Service goal have complex issues related to production, marketing, and management. The condition of the cage is not feasible, dirty, sanitation and hygiene is very bad, consequently diseased quail cattle reach an average of 35%. Productivity is very low, and having difficulty marketing eggs. Farmers also do not have a systematic bookkeeping related to finance and production process. Community service activities are carried out through Optimization of Cage Build Design, Optimization of Livestock Enviromental Environments, Quyry Health Control, Selection of Superior Seeds and Optimal Hatching of Eggs, Microcontroller Based Automatic Hatching Grants, and Marketing Strategy (Manual or Digital through Social Media) and Simple Operations and Financial Management.Keywords: automation, community service, microcontroler, quail farmers. ABSTRAK Kabupaten Bogor memiliki wilayah yang sangat luas, sehingga pangsa pasar untuk produk ternak juga terbuka luas. Pada tahun 2015 pemasok hasil ternak puyuh hanya ada 20 peternak dengan jumlah populasi puyuh berkisar 10 ribu ekor (Dinas Peternakan & Perikanan Kab Bogor). Hal ini menjadi peluang yang sangat baik bagi peternak puyuh, tetapi permasalahan yang dihadapi peternak puyuh ternyata sangat komplek. Dua peternak puyuh yang menjadi objek sasaran pengabdian masyarakat ini memiliki permasalahan yang kompleks baik terkait, produksi, pemasaran maupun manajemen. Kondisi kandang tidak layak, kotor, sanitasi dan higienitas sangat buruk, akibatnya ternak puyuh berpenyakit mencapai rata-rata 35%. Produktivitas sangat rendah, dan mengalami kesulitan memasarkan telur. Peternak pun tidak memiliki pembukuan yang sistematis terkait keuangan maupun proses produksi. Oleh karena itu kegiatan pengabdian masyarakat ini difokuskan untuk melatih, membina, memantau dan mendampingi kedua peternak tersebut dalam usaha meningkatkan produktivitasnya. Kegiatan pengabdian masyarakat dilakukan melalui Rancang Bangun Kandang Puyuh Optimal, Penciptaan Lingkungan Internal/Eksternal Peternakan yang Optimal, Pengendalian Kesehatan Puyuh, Pemilihan Bibit Unggul dan Penetasan Telur Optimal, Hibah Alat Penetas Telur Otomatis Berbasis Mikrokontroler, serta Strategi Pemasaran (Manual maupun Digital melalui Media Sosial) dan Manajemen Operasi dan Kuangan Sederhana.

Base on Honeywell Business FLEX® PKS™ Planning and Scheduling Optimization Engineering Study

Honeywell Business FLEX® PKS™ is a manufacturing executive system(MES) which is applicable to the process manufacturing firm to unify the supply chain plan, the service and the production automation, transferring the company's service goal to the definite operation goal and realizing the multi-varieties, multi-batch, high quality and low cost of the production demand. This paper has investigated on the enterprise productive plan and scheduler module to realise the system optimizations and product quality improvement as well as some key technical strategies. The paper also made an analysis for the numerous resources entity and functional module of the overall system and formed a research subject on the theory relative to the reliability growth of the MES. The research on the case has a certain instruction function for the enterprises which are going to put the MES into accurate, real-time data improves the decision-making process, and the resulting decisions improve customer service for all related information.

Domestic Violence and Sexual Assault Service Goal Priorities

We investigated agency directors’ perspectives about how service goals should be prioritized for domestic violence and sexual assault service subtypes, including crisis, legal advocacy, medical advocacy, counseling, support group, and shelter services. A sample of 97 (94% response rate) North Carolina domestic violence and/or sexual assault agency directors completed a survey asking participants to rank the importance of service goals. Overall, participants considered emotional support provision to be a critical service goal priority across all service types. Social support and self-care service strategies were deemed less important. However, prioritization of other service goals varied depending on the service type. Statistically significant differences on service goal prioritization based on key agency characteristics were also examined, and agency characteristics were found to relate to differences in service goal prioritization.
