Zemun Magistracy
fond maker history: Zemun Magistracy Local authority in Zemun, organized as Magistracy is set and established in 1751, right after Zemun became Free Military Community in 1749. Before Magistracy establishment, Zemun was under Ottomans rule from 1521 until 1717, and more as Christian than Muslim settlement; short time belonged under Vienna’s Court Chamber, from 1717 until 1728. It was also in private possession of Šenborn family including: Batajnica, Surčin, Dobanovci, Jakovo, Boljevci, Kupinovo, Obrež, Ogar, Karlovčić, Prahovo, Pećinci, Golubinci, Popinci and Vojka, until it was bought and associated with the Military Border 1749, as many assets in Srem, in fear of Ottomans invasion after they have already conquered Belgrade 1739. In development of the City Government in Zemun we can differentiate two periods: from establishment in 1751until 1871, when this institution performs as Zemun Magistracy, and period from 1871 until 1934 when it performed under different name as City Government in Zemun with some changes made in its organization. The Military Border, border area of Croatia and Slavonic, populated with Serbs, Croat, Romanians, Hungarians and number of Germans, organized as administration on military principle since XV century in purpose of defense from Ottoman Turks, during the rule of Maria Teresa (1746 – 1747) was divided on 5 border areas: Karlovac, Varaždin, Banat, Slavonia, Erdelj. Borders were divided on regiments, battalions, captaincy and municipalities. Zemun belonged to the Regiment of Petrovaradin, which represented Croat – Slavonic Border, together with Gradiška and Brod. In 1755, Zemun, as free Military Border, was extracted from the Regiment and directly subordinated to the command. From 1851 until 1869 it was in constitution of Serb – Banat Military Border. -

Productivity and Cost-Efficiency of Bundling Logging Residues at Roadside Landing
Original scientific paper – Izvorni znanstveni rad Productivity and Cost-Efficiency of Bundling Logging Residues at Roadside Landing Juha Laitila, Marica Kilponen, Yrjö Nuutinen Abstract – Nacrtak The aim of this case study was to clarify the productivity and cost of a system based on bun- dling logging residues at the roadside landing with the forwarder-mounted logging residue bundler. In order to find the bundling productivity, a set of time studies was carried out, in which several working techniques were tested and evaluated. The cost-efficiency of the roadside bundling system was compared with the conventional bundling system, wherein the logging of residue logs is made directly in the terrain and, after bundling, the logging residue logs are forwarded to the roadside landing with a forwarder. The harvesting cost (bundling and for- warding) of the extracted wood biomass to the roadside landing was calculated for bundling systems using time study data obtained from this study and productivity models and cost parameters acquired from the literature. The productivity of roadside bundling ranged from 48 to 53 logging residue logs per effective working hour (E0h), depending on the working technique used, and the mean time required to produce one logging residue log ranged from 83.6 to 92.3 seconds (E0h). The harvesting costs of the logging residue logs (€/m3) at the roadside landing were 11.5–13.7 €/m3 for the system based on bundling in terrain and 10.8–17.7 €/m3 for the system based on bundling at the roadside landing, when the forwarding distance was in the range 100–600 m and the removal of logging residues was in the range 30–90 m³/ha (m3 = solid cubic metre). -
Productivty and Cost of a Cut-To-Length Commercial Thinning
PRODUCTIVTY AND COST OF A CUT-TO-LENGTH COMMERCIAL THINNING OPERATION IN A NORTHERN CALIFORNIA REDWOOD FOREST By Kigwang Baek A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Resources: Forestry, Watershed, & Wildland Sciences Committee Membership Dr. Han-Sup Han, Committee Chair Dr. Daniel Opalach, Committee Member Dr. John-Pascal Berrill, Committee Member Dr. Alison O’Dowd, Program Graduate Coordinator May 2018 ABSTRACT PRODUCTIVTY AND COST OF A CUT-TO-LENGTH COMMERCIAL THINNING OPERATION IN A NORTHERN CALIFORNIA REDWOOD FOREST Kigwang Baek Cut-to-length (CTL) harvesting systems have recently been introduced to the redwood forests of California’s north coast. These machines are being used to commercially thin dense redwood (Sequoia sempervirens) stands which tend to form clumps of stems that vigorously sprout from stumps after a harvest. One of the challenges is to avoid damaging residual trees which can decrease productivity, increase costs, and lower the market value of trees. The goal of this study was to evaluate the productivity and costs associated with CTL systems used in a redwood forests and use that data to develop equations for predictions. Time and motion study methods were used to calculate the productivity of a harvester and forwarder used during the winter and summer seasons. Regression equations for each machine were developed to predict delay-free cycle (DFC) times. Key factors that influenced productivity for the harvesters was tree diameter and distance between harvested trees. Productivity for the harvesting ranged from 28.8 to 35.6 m3 per productive machine hour (PMH). -
Mechanized Tree Planting in Sweden and Finland: Current State and Key Factors for Future Growth

However, because of low cost-efficiency, the mechanization of Fennoscandian tree planting has been struggling. To determine key factors for its future growth, we compared the operational, planning, logistical, and organizational characteristics of mechanized planting in Sweden and Finland. Through interviews with planting machine contractors and client company foresters, we establish that mechanized tree planting in Sweden and Finland presently shares more similarities than differences. Some notable differences include typically longer planting seasons in Sweden, and a tendency towards two-shift operation and less frequent worksite pre-inspection by contractors in Finland. Because of similar challenges, mechanized planting in both countries can improve cost-efficiency through education of involved foresters, flexible information systems, efficient seedling logistics, and continued technical development of planting machines. By striving to have multiple client companies, contractors can reduce their operating radii and increase their machine utilization rates. Above all, our results provide international readers with unprecedented detailed and comprehensive figures and characteristics of Swedish and Finnish mechanized tree-planting activities. -

The Influence of German Settlers on the Formation and Development of an Industrial Town in Habsburg Bosnia: Teslić (1878-1918)
ISSN 0354-8724 (hard copy) | ISSN 1820-7138 (online) The Influence of German Settlers on the Formation and Development of an Industrial Town in Habsburg Bosnia: Teslić (1878-1918) Darko GavrilovićA, Goran VasinB, Dejan MikavicaB, Smiljana Đukičin VučkovićA, Ljubica Ivanović BibićA, Rastislav StojsavljevićAB* Received: September 06, 2017 | Revised: January 07, 2018 | Accepted: January 18, 2018 DOI: 10.5937/22-16623 Abstract This paper studies the formation and development of the Bosnian town of Teslić from the Austro-Hun- garian occupation of Bosnia and Herzegovina in 1878 to the end of the First World War in 1918. The goal is to emphasize the significant characteristics of the town’s development: the spread of capitalism; economic modernization; the arrival of a non-Slavic, predominantly German population; and the town as the leader of industrialization in Bosnia and Herzegovina. The industrial origin of Teslić and its struc- ture demonstrate Austria-Hungary’s need to economically integrate Bosnia and Herzegovina into its state area. The aim of this paper is to show to what extent the dynamics of industrial development in- fluenced the town’s formation and to see how the colonist population, which was mostly of German origin, influenced the industrial development and social life of the town. Keywords: German settlers, industrial town, development, Bosnia, Teslić Introduction In order to form a historical picture of the town of al development, which dictated the formation of this Teslić, we need to reconstruct a period of several dec- Bosnian town and the surrounding region. The sec- ades covering its formation and development as an ond part of the paper deals with the cultural devel- industrial settlement, and then its position as a small opment of the town, as well as with the labour un- town within Austria-Hungary (from the end of the ion battles that accompanied industrialization. -
Forest Fuel Harvest in Stands of Lodgepole Pine Have Also Been Studied
FOREST ENERGY FOR A SUSTAINABLE FUTURE Composite Report from the R&D Programme Efficient Forest Fuel Supply Systems 2011-2015 Today, primary forest fuel is extracted in the form of whole or partly delimbed trees in thinnings, as FOREST FUEL harvest energy wood (usually defective roundwood), as logging residue after final felling, or as stumps. The – TECHNOLOGY AND fuel various assortments differ in terms of harvesting METHODS FOR HARVEST method, but subsequent handling – forwarding, AND ASH RECYCLING Forest comminution and onward transport – is very similar. Örjan Grönlund & Henrik von Hofsten, Skogforsk In the period 2009 to 2013, the cost of harvest and terrain transport increased somewhat for all forest fuel assortments. In 2013 average costs per m3 of chips were SEK 52 for energy wood, SEK 43 for logging residue, i.e. branches and tops from final fellings, SEK 80 for small trees, and SEK 81 for stumps. The greatest potential for an increased harvest of primary forest fuels lies in stumps and small trees. Biomass prices have fallen in recent years, and costs must be reduced in all parts of the supply chain to retain profitability in the forest fuel business and to generate income for the forest owner. Logging residue Today, logging residue is harvested in most final fellings in southern and central Sweden. The work methods and technology used for residue-adapted harvesting and for- warding of residues can be regarded as mature and well proven, so fine-tuning of techniques and methods is becoming an increasingly important part of the work to improve efficiency. Planning tools like STIG and Grotsporre improve the planning and simplify the forwarding work, while considerably reducing the risk of ground damage.
