Opis:
The preliminary design of a multipurpose engineering machine on the wheeled chassis was presented in the paper. The machine meets a series of specific requirements such as: off-road prowess, ability of movement with high speed on hard-surface roads, limited weight and dimensions at the maintaining of great hoisting capacity. These requirements were adjusted to the present character of warfare and that is why the machine construction deviates from classic working machines being used in the civil sector. The meeting of defined requirements required the development of innovative methods. The solution aiming at the increasing the stability of the machine by the application of using a sliding drive unit was described. As a result of that, the increased capacity and efficiency of mined materials were obtained. Additionally, the system of two telescopic arms was applied, so that the efficiency was improved by the shortening of machine working cycles and it is possible to change the length of arms as well as both telescopic arms were placed on the rotating body achieving in such a manner the big workspace for arms. The 3D model of a multipurpose engineering machine and model with rear mounted drive unit and raised and extended arms are presented in the paper.

Opis:
The efficiency of wood transport depends not only on the maximum load capacity, but also on the duration of individual transport operations. The purpose of the presented research is to analyze the duration of transport stages of Scots pine large−size wood (saw logs) and indicate the factors that affect the structure of the duration of the entire operation. The operation was divided in to truck driving for a load on a public and forest road, driving between loading points in the forest including timber loading, driving with saw logs on a forest and public road, waiting for entry to the sawmill as well as verification and unloading of wood in the sawmill. Data on the duration of each operation was determined on the basis of information obtained from the course information cards. The waiting time for entering the sawmill as well as wood checking and unloading was based on data from wood reception in sawmill. 1514 randomly selected transports in a period of twelve months from 40 forest districts were analyzed. The average time of empty drive for a load by public road was 1:03 [hh:mm], with the range from 0:01 to 7:30. Driving time with a load to the sawmill was an average of 1:23, with the span from 0:05 to the 5:30. Driving on forest roads for load and with load is at a similar level of 11−12 minutes. The average time of loading wood in the forest was 39 minutes, with a minimum of 10 minutes, and maximum of 3 hours. Most trucks entered the plant immediately, nevertheless the average waiting time was 38 minutes, and the majority (75%) of transports need to wait up to one hour. Volume and quality checking, as well as unloading in the plant, took 42 minutes on average. The shortest delivery lasted 1:00 and the longest 17:37. The average transport duration of wood to the sawmill was 4:51. The number of places for loading wood in the forest has significant impact on the duration of collecting the load, and thus also on the time of the entire delivery. The largest fraction in the total duration of transport is associated with traveling on public roads. 27.1 and 28.8% is the time of loaded truck, and 20.5% and 21.7% is the time of the empty ride. A big difference (5%) occurs the time of collecting wood in the forest depending on the number of places from which wood was loaded. This time has a significant share (17.45%) in the structure of the delivery duration. Duration of the individual stages of wood transport in particular months shows little variability.

Opis:
The aim of the presented research was to characterize the driving related to the deliveries of large−size Scots pine wood and to determine the factors affecting its structure and distance. Operation was divided in to: driving for load on a public and forest road, forest ride between loading points, as well as driving with saw logs on a forest and public road. Data on the distance traveled on forest and public roads (empty and with load), as well as, the number of loading places was determined on the data from drivers. In total, 1509 randomly selected deliveries carried out over a period of twelve months from 40 forest districts were analyzed. Investigated transports delivered 44,336 m3 of large−size pine round wood to the sawmill. Most deliveries were made within 100 km from the plant. Within this radius, 83.87% of drives for load and 75.35% drives with load were completed. The average distance for driving for load on a public road was 60.6 km, with the range from 0.5 to 205 km. The average driving distance with load to the sawmill was 70 km, the shortest distance 2 km and the longest – 238 km. Driving distances on forest roads, for and with load, was on the similar level of 3.5 and 3.4 km, respectively. The average distance in the forest, between loading points was 3.1 km, with SD=2.9 km, maximum 16 km. The largest share, 51.4% of total delivery distance, was related to driving with saw logs on a public road and depends on how many places in the forest the wood was picked up. In 36% of all deliveries, saw logs were loaded from two or more places, which involved additional drive on forest roads at the distance of 1,652 km. The analysis did not show statistically significant differences between driving depending on the season of the year. The stable wood supply during 12 months period, shows that large stocks of round wood to secure productions during sensitive periods (winter), is not needed.

Opis:
The State Forests National Forest Holding that manages 77.1% of the forests in Poland intend to harvest over 40 million m³ of timber, which is supposed to supply the demand from some thousand timber processing companies. Introduction of a new normative for determination of the timber load weight as a result of multiplication its volume and wood density significantly changed timber transport regulations in 2012. The study analyzes the timber supply to a large (over 300 thousand m³ of wood per year) sawmill in the first half of 2012 and 2016. On the first date standard mass conversion indices were not implemented yet. We analysed whether there are significant differences in the timber deliveries between 2012 and 2016 with regard to monthly and weekly scale as well as in relation to the days of the week. In the first half of 2012 there was 4946 deliveries, which provided more than 126 thousand m³ of timber. In the same period of 2016 there was 6109 deliveries with total volume of 178 thousand m³. Increase in timber demand by 41% resulted in an increase in the number of transports only by 23.5%. Considering the distribution of the deliveries in each of 27 weeks, the average number of courses equal to 183 per week in 2012 and 226 in 2016. In first half of 2012, no courses were recorded in week 18, 26 and 27, while the highest number – in the week 16 (305 shipments). In 2016 only in first week there was no courses, and the maximum (312 deliveries) was reached in the sixth week. Average volume of weekly deliveries in 2012 amounted to 5234 m³, while in 2016 it reached 6595 m³. Maximum values equaled 7706 and 9026 m³ respectively. We noticed significant difference in the number of shipments and the volume of the delivered timber between the study periods, which results mainly from the increased production and demand.

Opis:
Timber hauling from the forest, either directly to the consumer or to the place of transshipment for a rail transport, is carried out by vehicles adapted to the transport of long or short logs and medium−sized wood. In Poland, regulations restrict the total weight of a vehicle traveling on roads, which consists of the weight of the empty vehicle and the weight of the load. When transporting the wood, the variability of the species, assortments, and wood moisture content does not allow for the unambiguous determination of the weight of transported timber, which often contributes to the excessive gross vehicle weight (GVW). In the conducted study, we analyzed Scots pine wood shipments (mainly short logs of length of 3.7−5.0 m) in different seasons of the year: in January (652 shipments), in March/April (1586), in July/August (1324), and in October/November (1914). GVW was calculated, based on the weight of an empty set and a weight of the load. The weight of the load was determined in two ways. In the first one it was calculated as a difference between loaded and unloaded truck. Measurements were carried out on the stationary scales. In the other method the volume of transported wood was taken from a delivery note and multiplied by the conversion rate for Scots pine, which equals 0.74 Mg/m³. The difference between both calculation methods reached 17%. It was found that in 2016 timber loads varied greatly, ranging from 41.3 to 66.9 Mg. The average GVW for the year 2016 was 50.64 Mg and it was on the similar level as in 2009 – 51.12 Mg on average, ranging from 40.06 to 64.20 Mg.

Opis:
Monolithic nitrocellulose and cellulose composites (NC-C) were obtained by cross-linking a mixture of nitrocellulose with cellulose using hexamethylene diisocyanate (HDI). They were incorporated into a model reactive armour. An X-ray technique was used to examine the infuence of the cellulose content on the accelerating ability of the gaseous reaction products of the composites. The modifed Gurney model was used to simulate the process of driving steel plates in the reactive armour after jet impact. Formulae for the determination of the time-space characteristics of the plates’ movement were derived. The results of the X-ray recording of the plates driven by the explosion products of monolithic nitrocellulose and cellulose composites (NC-C) were used for the verifcation of the model.

Opis:
The aim of this study was to assess the growth and development of plants of three strawberry cultivars fertilized with selected biofertilizers under greenhouse conditions. The experiments were conducted in a greenhouse complex of the Research Institute of Horticulture in Skierniewice from February to July in 2013 and 2014. Plants of three strawberry cultivars, ‘Elsanta’, ‘Honeoye’ and ‘Elkat’, were planted in rhizoboxes and grown under the following fertilization regimes: 0-control (no fertilization), NPK control, Micosat F (bacterial-mycorrhizal substrate), manure, Humus UP, and Vinassa. Applications of Humus UP resulted in beneficial effects on plant height, leaf surface area, leaf fresh and dry weight, the degree of mycorrhizal colonization in the roots, and on the num-ber of spores of arbuscular mycorrhizal fungi in the rhizosphere of strawberry plants. Biopreparations Humus UP and Vinassa also had a positive influence on the size of the root system, the total number of bacteria, including spore-forming bacteria, and the total number of filamentous fungi in the rhizosphere soil, compared with mineral NPK fertilization under greenhouse conditions.
Celem przeprowadzonych badań była ocena wzrostu i rozwoju trzech od-mian roślin truskawki nawożonych bionawozami w warunkach szklarniowych. Doświadczenie przeprowadzono w kompleksie szklarniowym Instytutu Ogrodnictwa w Skierniewicach w latach 2013 i 2014 (w okresie od lutego do lipca). Rośliny trzech odmian truskawki Elsanta, Honeoye i Elkat posadzono w rizoboksach i zastosowano następujące nawożenie: kontrola 0 (bez nawożenia), kontrola NPK, substrat bakteryjno-mikoryzowy Micosat, obornik, Humus UP i Vinassa. Aplikacja Humusu UP miała korzystny wpływ na wzrost roślin, pole powierzchni liści, ich świeżą i suchą masę, stopień kolonizacji miko-ryzowej w korzeniach oraz liczbę spor arbuskularnych grzybów mikoryzowych (AMF) w rizosferze roślin. Biopreparaty Humus UP oraz Vinassa miały również pozytywny wpływ na wielkość systemu korzeniowego, ogólną liczbę bakterii, liczbę bakterii wytwarzających formy przetrwalnikowe i ogólną liczbę grzybów strzępkowych w glebie rizosferowej roślin truskawki, w porównaniu z nawożeniem mineralnym NPK w warunkach szklarniowych.

Opis:
In the present work, the confined explosions of cylindrical homogeneous and layered charges composed of two different types of macroscopic granular multi-component RDX-based composites were investigated. These composites were obtained by the so-called “wet slurry method”. For comparison, charges consisting of simple mixtures instead of the composites, TNT and phlegmatized RDX (RDXph) were also studied. The effect of the following parameters: the structure of the macroscopic granular composite, the type of charge (cylindrical pressed material or layered with an RDXph core), oxygen availability (air or argon atmosphere) and the aluminium particle size, on the quasi-static pressure (QSP) measured inside a 150 dm3 explosion chamber was determined. Solid post-detonation residues from inside the explosion chamber were also collected and analyzed. A combination of all of these results enabled very important conclusions about aluminium combustion and behaviour during the explosion of composite and layered charges, to be drawn.

The aim of the study was to determine the effect of various biopreparations on the growth of the apple root system, the number of spores of AMF, the total number of bacteria and microscopic fungi in the rhizosphere soil, and the degree of mycorrhizal association in the roots of two apple tree cultivars. The experiment was established in the spring of 2009 in the Experimental Orchard of the Institute of Horticulture in Dąbrowice. The research objects were one-year-old maidens of the apple cultivars ‘Topaz’ and ‘Ariva’ grafted on M26 rootstock. The trees were treated with the following biopreparations: control, control NPK (standard NPK fertilization), manure, Micosat F + manure, Humus UP, Humus Active + Aktywit PM, BioFeed Amin + manure, BioFeed Quality + manure, Tytanit + manure, Vinassa + manure, Florovit Eko, and Florovit Pro Natura. Treatment of ‘Topaz’ and ‘Ariva’ apple trees with the biopreparations Micosat F, Humus UP, Humus Active + Aktywit PM, BioFeed Amin, Vinassa, Florovit Eko and Florovit Pro Natura produced positive effects on the growth of apple roots and their mycorrhizal frequency, and the size of the populations of microorganisms in the rhizosphere soil.

Opis:
The aim of the study was to evaluate selected bioproducts in terms of their effects on tree growth and the presence of mycorrhizal fungi in the roots of trees of two apple cultivars, ‘Topaz’ and ‘Ariwa’, grown under greenhouse conditions. The trees were planted in rhizoboxes and grown under the following fertilization regimes: 0 – control, NPK control, manure, Micosat F, Humus UP, Humus Active + Aktywit PM, BF Amin, BF Quality, Tytanit and Vinassa. The results showed that the biostimulants: Humus UP, Humus Active and Aktywit PM produce beneficial effects on the morphological characteristics of the root system, and Micosat F on the extent of mycorrhiza formation in the roots. The bioproducts used are a safe, effective and economically viable method of fertilizing plants, limiting the use of chemical means of production and thus helping to protect the environment.
