Chainsaw is the main tool for work, considering the terrain and soil in our country, in the process of the harvesting, and there is a big chance it will be the main tool in the future too. The goal of the research is to determine fuel and lubricant consumption of the chainsaw Husqvarna 372 XP, during the harvesting and making forest wood assortments, on the area of the Public enterprise forest, Vareš, section 37.
During the research, 50 trees of the fir and spruce have been felled. Range of the diameter was from 8 to 76 cm, and the volume of the assortments was 86.16 m3. Volumetric method is applied in the measurement of fuel and lubricants, with precise determination of how much fuel it was in the thanks.
Analysis showed that there is a strong correlation between consumption of the fuel and lubricant (L/m3) in relation to the size of the breast height diameter.
Average fuel consumption in the process of logging and preparation was 0.104 L/m3, while the average consumption of lubricant was 0.023 L/m3.
It is necessary to continue to pay great attention to the rationalization of consumption on fuel and lubricants, as well as reducing their harmful effects on humans and environment (introduction and usage of biodegradable fuels and lubricants).

Numerous studies have found that essential oils have significant inhibitory activity against human viruses, but there is scarce information on the effects of essential oils on plant viruses. In this study, effects of cajuput (Melaleuca leucadendron (L.) L.), common myrtus (Myrtus communis L.) and winter savory (Satureja montana L.) essential oils were assayed against Tobacco mosaic virus (TMV) by inoculation in different plant host systems. Antiphytoviral activity of the essential oils was determined by the half-leaf method using test plants: Chenopodium quinoa Willd., Cucumis sativus L. 'Cornishon' and Phaseolus vulgaris L. 'Top Crop'. Results showed that investigated oils posess strong antiviral activities. Among tested oils, the highest and broadest acitivity was shown by winter savory essential oil. Evidence suggests that investigated essential oils are possible antiphytoviral agents.

Total of 125,479 ha of different stated owned forest cultures were registered in the territory of Bosnia and Herzegovina (1990). Stability of forest even – aged stands and forest communities in genera has been endangered by damaging biotic and abiotic factors of local and global nature. The biggest damages on forest cultures have been caused by insects and fungi, biotic factors, and snow and wind, abiotic. The negative influence of global factors, that is, global climate changes has recently stood out.
The aim of this research was to determine of health status of forest even – aged stands. Research for the purpose of this work has been carried out in the territory of Forest management Jahorina, Pale with three forest even – aged stands: Norway spruce, Scots pine and forest even – aged stands of other coniferous (European larch and Douglas fir).
Research included 796 trees of Norway spruce, Scots pine, European larch and Douglas fir.
Presence of insects was identified on 15,58%; fungi on 2,14%, and mechanical damages on trunk and/or crown 11,06% of the total number of examined trees. Of the total number of examined trees, the share of mechanical damages on trunk and/or crown of trees is as follows: first crown, and then trunk. Share of trees with mechanical damages on both crown and trunk is rather small. Identified damaging biotic and abiotic factors do not cause significant damages on the analyzed forest even – aged stands.

This paper analyses the dynamics of diameter structure and height curves as the main indicators of a simple stand structure, uneven-aged multi-storied fir and spruce stands in the management unit „Igman“ where selective felling is applied based on the principle of positive selection. The data for analysis was collected by periodical measurement during fifty years on two permanent sample plots, forest sections 43 and 58. It has been determined that during the observation period there had been a change in diameter structure in the sense of increase in the proportion of trees in the lower, and decrease in higher diameter classes as well as the increase of tree height in the complete interval of empirical data. It has been concluded that due to selective felling, with higher diameter classes trees included, conditions have been created for the occurrence of new and the development of the existing young crop; diameter structures of a shape characteristic for even-aged stands have gradually assumed the shape characteristic for selective stands. Thus, due to the increase of competition among the trees of lower diameter classes and the felling of lower height and lower quality trees of higher diameter classes, there has been an increase in the height of trees of the same diameter.

The paper presents the distribution and diversity of macrozoobenthos composition of Bosna river up to Zenica, from 1999 to 2010. Macrozoobenthos has been chosen as an element of bioevaluation of the ecological state of running water, and according to the provisions of the Water Framework Directive. Sampling has been done by using the kick-sampling amd multihabitat method, a standard for hydrobiological research. The highest diversity of macrozoobenthos has been found in samples from the sites Rimski most (36 taxa), and the lowest was at site of the Bosna River upstream from the mouth of Ljubina river and downstream of the mouth of the Zgošća river (4 taxa). According to abiotic conditions which directly affect the composition of macrozoobenthos, and using Bray-Curtis similarity, the highest degree of similarity has been found in sites which are spatially nearby. Taxa number and EPT taxa number were highly correlated (R2 = 0,871). Saprobic index and BMWP index were calculated in assessing the ecological status of the river Bosna at the study sites. The values obtained comparing EPT taxa number and BMWP index show a high correlation (R2 = 0,706). The composition and the distribution of the macrozoobenthos in the Bosna river are conditioned by abiotic parameters. Sites upstream of the mouth of the Ljubina river and downstream from the mouth of the Zgošća river represent the places with the highest pollution which is the result of point and diffuse sources of pollution.

Springs are recognized as hotspots for freshwater biodiversity conservation. The study objective was to analyze and compare the biodiversity of epilithic diatom communities of spring and stream habitats in the Konjuh Mountain (B&H). The measuring of basic water physical and chemical parameters and diatom sampling were carried out during summer and autumn period in 2013.
Diatom assemblages were collected from 10 locations: (i) five locations were placed in small mountain springs that flow into headwater streams, where another 5 localities were placed. Diatoms were collected by scrubbing the rocks using standard methodology. Relative diatom cell abundances were established by counting up to 400 frustules on permanent slides prepared in Naphrax.
Spring habitats were more diverse in diatoms (H' loge =1.67 average) in comparison with headwater stream habitats (H' loge=1.15 average), which was confirmed by t-test (t=2.79; p=0.013). The similarities of community structure from different habitats were investigated by non-metric multidimensional scaling, on the Bray-Curtis similarity matrix in software package Primer 6.
Using Permutational Manova test, a different diatom composition was proved between spring and stream communities (Pseudo F=2.66, p=0.012), while the seasonal difference in the community structure was not confirmed (F=0.586, p=0.876). The most abundant and frequent species in spring habitats were: Achnanthidium minutissimum (Kützing) Czarnecki, Cocconeis pseudolineata (Geitler) Lange-Bertalot, Gomphonema pumilum var. elegans E.Reichardt & Lange-Bertalot, Meridion circulare (Greville) C.Agardh and Planothidium lanceolatum (Brébisson ex Kützing) Lange-Bertalot. The most frequent and abundant species in headwater stream habitats were: Achnanthidium minutissimum (Kützing) Czarnecki, Cocconeis placentula var. euglypta (Ehrenberg) Grunow, Cocconeis placentula var. lineata (Ehrenberg) van Heurck and Cymbella tridentina Lange-Bertalot, M.Cantonati & A.Scalfi.
In comparison with streams habitats, the springs are heterogeneous with specific diatom composition due to more stable water flow. Although the springs cover very small areas, the diversity of species that inhabit them must not be neglected in planning the use of these natural resources.

This paper presents the research results of the skidding productivity for the Ecotrac 120V skidder in mountainous areas of MU „Igmanˮ in Bosnia and Herzegovina. Time and work study were performed. Multiple regression analysis was used for determination of work operations time consumption depending on influencing factors. The following influencing factors were recorded: the condition of the tractor road (surface), the skidding distance, the winching distance, number of pieces in the load, the volume of the load and the slope of the tractor road. The share of productive time in the total work time is 58.47%. The average value of the influencing factors was established: unloaded travel distance 585.26 m, loaded travel distance 490.49 m, winching distance 16.83 m, number of pieces in the load 5.95, the volume of the load 5.17 m3 and the volume of the piece in the load 1.02 m3. The half-tree length method was used. Standard time for skidding and daily skidding productivity were expressed depending on the skidding distance, while average values were used for other influencing factors. The standard time for skidding was 6.57 min/m3 at a skidding distance of 100 m, i.e. 17.60 min/m3 at a skidding distance of 1,500 m. The daily skidding productivity ranges from 73.07 m3/day at a skidding distance of 100 m to 27.28 m3/day at a skidding distance of 1,500 m. Comparison of the daily skidding productivity with the results of other researches showed that the Ecotrac 120V skidder in this particular case realizes approximately the same skidding productivity under similar working conditions.

This paper presents the research results of benthos community (phytobenthos and macroinvertebrates) on three locations of the Neretva River: Glavatičevo, Žitomislići and Višići. According to typology of rivers, the site Glavatičevo belongs undertype 10a, while sites Žitomislići and Višići are undertype JIVT (heavily modified water bodies). Research of the benthos community has been done in December 2016 with the simultaneous monitoring chemical parameters of water. All research states showed a great number and a high diversity of benthic taxa, although sampling was spent in December. The saprobic values of benthos community at the site Glavatičevo indicates to oligosaprobic level, the water unloaded with organic substances. The site Žitomislići points to oligo/betamesosaprobic level, the water a bit loaded with organic substances. The site Višići according to phytobenthos demonstrates to oligo/betamesosaprobic level, while according to benthic macroinvertebrates point to betamesosaprobic level (the water loaded with organic substances). Based on saprobic values and chemical parameters of water in keeping with The decision on the characterization of the surface and underground water, reference conditions and parameters for the detection of water state and water monitoring (Official newspapers FBiH, No. 1/14), a maximum ecological potential has been registered on sites Žitomislići and Višići, while a high ecological status has been registered on the site Glavatičevo.

Published: January 2022

ABSTRACTObjectiveChiropractic lecturers sit at the interface between theoretical education and the transition to clinical practice. They are central to a positive and high-quality learning environment. This study aimed to explore how chiropractic students in the United Kingdom rate the importance of lecturer qualities and their influence on overall preregistration course experience.MethodsAn online mixed-method questionnaire was used. Data were converted into proportions with lower and upper limits of the 95% confidence interval (CI). Likert-scale questions were treated as numeric variables with the mean, mode, median, and percentage calculated for combined responses. Thematic analysis reported patterns of data extracted from open-ended questions.ResultsOf the population of current UK chiropractic students, 195 completed the questionnaire. Five out of 12 teaching roles were rated as very important, including the ability to deliver high-quality information and evaluate the curriculum (mean = 4.71). Communication ranked as the number 1 personal quality followed by command of the subject. Lecturers were perceived as very important to overall course enjoyment (mean = 4.88) and students' ability to succeed (mean = 4.54). Students felt it was more important that lecturers were clinically active (84%; 95% CI, 78%–89%) than research active (25%; 95% CI, 19%–31%).ConclusionChiropractic students in the United Kingdom recognize the significance of lecturers in the educational experience. A range of qualities were considered important relating to overall course enjoyment and student outcomes. Clinically active lecturers facilitate student development. Of importance, students felt course evaluation and curricula development were valuable qualities in the modern-day lecturer.

AbstractHigh‐frequency responsive capacitors with lightweight, flexibility, and miniaturization are among the most vital circuit components because they can be readily incorporated into various portable devices to smooth out the ripples for circuits. Electrode materials no doubt are at the heart of such devices. Despite tremendous efforts and recent advances, the development of flexible and scalable high‐frequency responsive capacitor electrodes with superior performance remains a great challenge. Herein, a straightforward and technologically relevant method is reported to manufacture a carbon fabric membrane “glued” by nitrogen‐doped nanoporous carbons produced through a polyelectrolyte complexation‐induced phase separation strategy. The as‐obtained flexible carbon fabric bearing a unique hierarchical porous structure, and high conductivity as well as robust mechanical properties, serves as the free‐standing electrode materials of electrochemical capacitors. It delivers an ultrahigh specific areal capacitance of 2632 µF cm−2 at 120 Hz with an excellent alternating current line filtering performance, fairly higher than the state‐of‐the‐art commercial ones. Together, this system offers the potential electrode material to be scaled up for AC line‐filtering capacitors at industrial levels.

Published: January 2022

AbstractWe performed a bromination reaction of dinaphtho[2,1‐b:1′,2′‐d]furan (DNF). Although similar reactions have been reported, the regioselectivity of this reaction has not been clarified. Single‐crystal diffraction study confirmed that two bromine atoms were introduced on 5‐ and 9‐positions of DNF. Detailed studies revealed that the steric effect of the bulky bromine atoms propagated through the peripheral hydrogens and/or the skeleton of DNF to result in the large helicity. This structural characteristic became apparent from the shift of the signals of Fjord hydrogens in the 1H NMR spectra. Theoretical studies also supported our proposed remote steric effect.

Published: January 2022

AbstractIn this article, we study the impulsive consensus problem of linear multi‐agent systems composed of α‐order conformable differential equations (α ∈ (0, 1]). Two cases of fixed and switching interaction networks are considered, respectively. Impulsive protocol of each agent is introduced based on the local information of the interaction networks. Firstly, we derive the analytic solution of the general linear conformable systems with impulses. Secondly, two sufficient criterions are presented to guarantee the convergence of the consistent state for all the agents by using matrix theory, graph theory, and impulsive control theory. Finally, three numerical simulations are provided to demonstrate the obtained theoretical results and to compare the convergence rates of the systems with distinct orders.
Wheat cover crop and seed treatment for improving native warm‐season grass establishment
Authors: Keyser Patrick D. , Ashworth Amanda J. 
Published: January 2022

AbstractSwitchgrass (Panicum virgatum L.) and other perennial native warm‐season grasses (NWSG), such as big bluestem (BB) (Andropogon gerardii Vitman) and eastern gamagrass (EG)[Tripsacum dactyloides (L.) L.] are excellent biofeedstocks, forages, and dual‐purpose biomass–forage crop candidates. However, reliable establishment is a challenge. Therefore, we conducted an experiment at two locations in Tennessee, repeated over 2 yr (2012 and 2013) to evaluate establishment strategies for BB, EG, and switchgrass. Treatments included a wheat (Triticum aestivum L.) cover crop with and without inorganic nitrogen (60 and 0 lb acre–1) and an insecticide–fungicide seed treatment (Gaucho XT and an untreated control). Although establishment success varied by site and year, switchgrass generally produced stands with greater seedling densities than BB, with EG producing the weakest stands. The N treatment did not affect NWSG seedling density or yields in subsequent years at either location for either planting year. Seed treatment improved seedling density in 2013 at one location for switchgrass but not the other species (P = .029). At the second location, seed treatment improved seedling density (0.43 vs. 0.29 seedlings ft–2) across all species (P = .006), apparently driven by the response of BB (0.69 vs. 0.44 seedlings ft–2; P = .094). Neither treatment influenced yield, which increased (P < .001) each year (1.91, 2.69, and 3.60 ton acre–1) across all species. According to these results, dormant‐season NWSG planting in wheat appears to be equally successful regardless of N fertilization. Seed treatments offer some potential for improved establishment success.
