Opis:: Scentless chamomile Matricaria maritima (L.) ssp. inodora (L.) Dostal and common poppy Papaver rhoeas (L.) are species which very often infest winter cereal and winter rape crops. Inhibitors of acetolactate synthase (ALS) are commonly used for control of these weeds. The herbicides are characterised by a single site of action in the plant, which has an influence on selection of the weed population and may result in a rapid development of resistance. In 2012, five seed samples of scentless chamomile and five samples of common poppy were collected from five winter wheat crop fields in Żuławy Gdańskie where the weed species were very poorly controlled. Results of greenhouse experiments showed that two biotypes of scentless chamomile and common poppy were resistant to tribenuron methyl. It was not possible to control resistant biotypes even after use of tribenuron methyl at a dose four times higher than recommended in Poland, it is the first reported case of scentless chamomile and common poppy biotypes’ resistance to herbicides. It is not of economic importance but it does prove the growing problem of weed resistance in the country.

Opis:: Alopecurus myosuroides seeds were sampled from 32 winter wheat fields from 2010 to 2014. Resistance to herbicides was detected in 17 A. myosuroides populations. In addition to single resistance to herbicides, cross-resistance and multiple resistance to acetolactate synthase (ALS)- and acetyl-coenzyme A carboxylase (ACCase)-inhibiting herbicides were found. Application of sulfometuron and imazapyr was unable to control some of the resistant biotypes in this study. This result implies that resistance in these populations is due to a target site mechanism. The A. myosuroides biotypes resistant to ACCase-inhibiting herbicides varied in their responses to derivatives of aryloxy-phenoxy-propionic acid (FOPs), cyclohexanediones (DIMs) and phenylpyrazolines (DENs). Resistant biotypes of A. myosuroides that could not be controlled with fenoxaprop-P-ethyl (FOP) and pinoxaden (DEN) were controlled with clethodim (DIM).

Opis:: Between 2004 and 2017, multiple studies on the herbicide resistance of weeds were conducted by the Institute of Plant Protection – National Research Institute in Poland. Weed seeds, collected from fields located in various regions of Poland where herbicide use was ineffective, were used in studies conducted under greenhouse conditions. A total of 261 loose silky bent (Apera spica-venti L.) samples were found to be herbicide resistant, which translates to 52.4% of the fields under study. Nearly 50% of the analyzed samples exhibited resistance to sulfonylurea herbicides. Resistance to acetyl CoA carboxylase (ACCase) inhibitors was found in 18 fields, whereas resistance to photosystem II (PSII) inhibitors (isoproturon) was found in 12 fields. Herbicide resistance of blackgrass (Alopecurus myosuroides Huds.) occurred in 26 of the fields under study. In addition, resistance of wild oat (Avena fatua L.) to acetyl CoA carboxylase inhibitors occurred in 10 spring cereal crops. In the case of winter wheat, resistance of cornflower (Centaurea cyanus L.) to tribenuron-methyl occurred in 23 fields. Scentless chamomile (Matricaria inodora L.) and field poppy (Papaver rhoeas L.) were resistant to tribenuron-methyl in four and three fields, respectively, of winter wheat. In the case of sugar beet, three biotypes of fat hen (Chenopodium album L.) and two biotypes of redroot amaranth (Amaranthus retroflexus L.) were resistant to metamitron. Horseweed (Conyza canadensis L.), which grows on railway tracks, exhibited resistance to glyphosate. This paper reviews all studies conducted in Poland on weed resistance. Based on the results, maps of weed resistance in Poland were created.

Opis:: The authors have made an attempt to enrich the knowledge about the influence of wax pattern washing process and its influence on the quality of the shell prime coat. Two types of wax were investigated: A7Fr/60 and KC2690. A7Fr60 is used for pattern fabrication, while KC2690 is typical sprue wax. The goal of work was to establish wax solubility accuracy in Trisol 60 Plus and Houghto Clean 530 versus time and influence of dipping time to wax samples surface quality. Additionally, after exposition of wax samples, their surface morphology was characterized with the use of laser profilometry and surface roughness measurement. The quality of formed prime coat was established by X-ray tomography. The measurement of wetting angle of the wax by binder was conducted. The results have shown that the main factor which influences the quality of the prime coat is surface wettability rather than wax surface roughness.

Opis:: The study investigated the properties of selected certified mixtures used to make wax patterns for the production of precision castings for the aerospace industry. In addition, an assessment of the recycled mixtures consisting of certified wax materials recovered during autoclaving was carried out. Hardness was tested via a proposed method based on penetration, creep related deformation, bending strength and linear contraction. The hardness was studied on laboratory specimens and patterns made with the use of injection molding equipment. For these patterns, linear contraction was estimated at variable pressure and for different temperature injection parameters. Deformations connected with creep and resistance were evaluated on cylindrical specimens. Differences in creep resistance in relation to the hardness were observed depending on the type of pattern mixtures. Recycled mixture has a greater resistance and smaller linear contraction than certified mixtures used for making sprue, raisers and other parts of filler system.
W pracy zbadano właściwości wybranych mieszanek modelowych atestowanych stosowanych do wykonywania modeli wytapianych przy produkcji odlewów precyzyjnych dla przemysłu lotniczego. Dodatkowo badaniom poddano masę z recyklingu składająca się z odzyskanych w procesie autoklawizacji mieszanek woskowych atestowanych. Zaproponowano badania twardości metodą penetracji, odkształceń związanych z pełzaniem, wytrzymałości na zginanie oraz skurczu liniowego. Twardość badano na próbkach laboratoryjnych oraz na modelach wykonanych na wtryskarce przemysłowej. Dla tych modeli oszacowano skurcz liniowy przy zmiennych parametrach ciśnienia i temperatury wytrysku. Odkształcenia związane z pełzaniem i wytrzymałość badano na modelach walcowych. Obserwuje się różnice odporności na pełzanie w odniesieniu do twardości w zależności od rodzaju mieszanki modelowej. Masa z recyklingu ma większą odporność i mniejszy skurcz liniowy niż masa atestowana stosowana na układy wlewowe.

Opis:: The paper presents the possibility of using CAD/RP for the design and manufacture of the core models used for precise casting of core aircraft engine turbine blades, with directional crystallization process and single crystallization. The process of modelling 3D CAD geometry of research blade in relation to the model of the core was presented. The sample design, blade base model, was made by one of the incremental method of rapid prototyping - Jetting System. The geometry of the blade model has been designed in a way, which allows making a silicon form on the basis of a base prototype in the process of rapid prototyping tools (Rapid Tooling). The form allows the attachment of the blade core in a place designed specifically for this purpose. The silicon form has enabled the production of wax models with the inner core. This task was achieved by proper shaping of forms with the plane of its division. The resulting models were used to make ceramic moulds and carry further work on the development of casting technology in the process of directional crystallization and single crystallization of core blades of aircraft engines.

Opis:: Manufacturing of aircraft engine turbine blades requires control of blade geometric parameters at different stages of technological process. Acceleration and automation of measurement process can affect the duration of the finished item production. Modern technologies for measurement of aircraft engine turbine blades are based on numerical machines - measurement process is based on processing of numerical data obtained by measurement using coordinate measuring machines. The paper presents the opportunity of automation of aircraft engine turbine blades measurements using scanner ATOS II Triple Scan with blue light source technology. Coordinate measuring technique allows to specify full methodology for designation of complex dimensions of physical objects and transform them into a computer program space of coordinate measuring devices. Presented paper includes capabilities of device used in the study to improve the measurement process in the technological and economical aspects. Another issue described in the paper is impact of measurement performance in automatic mode on the quality of performance – the numerical model of surface, from the standpoint of accuracy and number of collected data points in time. The paper includes an analysis of conditions related to the measurement works, such as the process of preparing the model, measurement equipment and data processing capacity. As the result methodology for automated scanning measurements of aircraft engine turbine blades will be presented.

Opis:: Tortoises are a novelty in the world of pets. Although a great deal of information has been acquired on the internal medicine and surgery on these animals, little is known of their parasitological fauna. Fecal samples of 11 species of tortoises housed in the City Zoological Garden in Wroclaw were examined. Eggs of parasitic helminths were isolated using flotation and sedimentation techniques. The overall prevalence was 81.2%. Two groups (Nematoda and Trematoda) of endoparasites were found. Oxyurid eggs were found almost in every animal examined. Co-infection with oxyurids and ascarids was recorded for T. horsfieldii and T. marginata. Three species of tortoises were infected by digenic trematodes.

Opis:: 4BrABT (2-(4-Bromophenylamino)-5-(2,4-dihydroxyphenyl)-1,3,4-thiadiazole) is a compound known for its interesting in vitro anticancer profile. 4BrABT inhibited proliferation and motility of several cancer cell lines in concentrations which were not toxic to normal cells. A major problem associated with cancer chemotherapy, but also caused by environmental factors such as pesticides, is neurotoxicity. Therefore, the aim of the presented study was an in vitro evaluation of the neuroprotective activity of this compound. 4BrABT activity (1–100 μM) was tested in cultures of mouse neurons, rat astrocytes and rat oligodendrocytes. A possible protective action of the compound in different neurodegenerative models, as serum deprivation (SD), excitotoxicity (presence of 500 μM glutamate in culture medium), as well as cisplatin toxicity (astroglia – 50 μM and oligodendroglia – 100 μM) was investigated. Cell viability in the tested cultures was assessed with the use of LDH and MTT methods. Moreover, 4BrABT ability to prevent the cisplatin-induced apoptosis in astrocyte and oligodendrocyte cultures was analysed after Hoechst 33342 fluorostaining. The obtained results indicate that 4BrABT was not toxic to neurons, astrocytes and oligodendrocytes. Moreover, a decrease in the neuronal LDH level was observed, which may suggest the ability of 4BrABT to act as a trophic agent. Furthermore, the protective action of the studied compound was shown in neuronal cultures exposed to neurotoxic conditions (presence of glutamate and trophic stress) and in cisplatin-treated astrocytes and oligodendrocytes. The expression of anticancer and neuroprotective activity raises hopes for the potential use of 4BrABT as a safe anticancer drug, or neuroprotective agent in chemotherapy-associated neurotoxicity.

Opis:: The aim of the field experiments carried out in the years 2009–2011 was to assess the application of reduced doses of chlorsulfuron on yield and quality parameters of winter triticale semi-dwarf and full-height cultivars. The herbicide effect was evaluated in two cultivars, Grenado and Pizarro. The cultivars were of different plant heights. Chlorsulfuron was applied at the recommended dose (15 g a.i. ∙ ha–1), at areduced dose (10.5 g a.i. ∙ ha–1) and at areduced dose with an adjuvant. Treatments with the herbicide were conducted directly after the triticale had been sown. Visual assessment of weed infestation was carried out in spring, after the start of the vegetation of the cultivated plant. The study assessed triticale grain yield, grain number per ear, thousand grain weight, and selected qualitative parameters of grain (protein and starch content). The obtained data proved the usefulness of reduced doses of chlorsulfuron in weed control both separately and in a combination with the adjuvant. The average percent of the weed control was very high for both cultivars and for the assessed doses of herbicide. Both experimental factors (herbicide dose and triticale cultivar) influenced the level of the obtained grain yield of triticale, and the thousand kernel weight. While grain number per ear and protein and starch content depended only on the examined cultivar.

Opis:: Ścisłe jednoczynnikowe doświadczenia polowe w układzie losowanych bloków w czterech powtórzeniach wykonano w latach 2006-2008 w trzech lokalizacjach: w Kurowie w powiecie kościańskim (52o07’ N; 16o39’ E), w Czerniejewie w powiecie gnieźnieńskim (52o26’ N; 17o29’ E) oraz w Winnej Górze w powiecie średzkim (52o12’ N; 17o27’ E). Przedmiotem badań była ocena możliwości zastosowania wybranych herbicydów w uprawie sorga zwyczajnego odmiany Sucrosorgo 506. Oceniano następujące środki chemiczne: Dual Gold 960 EC 1,5 dm3·ha-1 (s-metolachlor), Trophy 768 EC 2,5 dm3·ha-1 (acetochlor), Banvel 480 SL 0,5 dm3·ha-1 (dikamba), Mustang 306 SE 0,6 dm3·ha-1 (florasulam + 2,4D), Aminopielik Gold 530 EW 1,25 dm3·ha-1 (fluroksypyr + 2,4D), Callisto 100 SC 1,5 dm3·ha-1 (mezotrion), Chwastox Extra 300 SL 3,0 dm3·ha-1 (MCPA), Chwastox Turbo 340 SL 2,0 dm3·ha-1 (MCPA + dikamba) oraz MaisTer 310 WG (foramsulfuron + jodosulfuron metylosodowy) z adiuwantem 0,15 kg·ha-1 + 1,5 dm3·ha-1. Przeprowadzono ocenę skuteczności chwastobójczej, analizę świeżej masy roślin sorga oraz określono obsadę roślin na jednostce powierzchni. Efekt stosowania wybranych herbicydów był zróżnicowany w latach. Po zastosowaniu herbicydów Trophy 786 EC (rok 2006) i Chwastox Turbo 340 SL (2008 r.) świeża masa roślin sorga była istotnie wyższa od masy roślin z obiektu kontrolnego, natomiast istotnie większą obsadę roślin odnotowano w roku 2006 po użyciu środka Chwastox Turbo 340 SL oraz w roku 2007 – po wykorzystaniu preparatów Banvel 480 SL i Chwastox Turbo 340 SL. Maister 310 WG stosowany łącznie z adiutantem spowodował całkowite zniszczenie rośliny uprawnej.
In 2006-2008 strict, one-factorial field experiments were established in randomized block design with the control in four replications at three fields situated in Kurowo (52o07’ N; 16o39’ E), Czerniejewo (52o26’ N; 17o29’ E) and Winna Góra (52o12’ N; 17o27’ E). The main goal of the presented paper was to evaluate the selected herbicide selectivity and effectiveness in cultivation of the sorghum cultivar Sucrosorgo 506. Sorghum is considered a minor crop in Poland. There are no registered herbicides, so it is necessary to provide management options for weed control in sorghum. The following active ingredients were tested: s-metolachlor (Dual Gold 960 EC 1.5 dm3·ha-1), acetochlor (Trophy 786 EC 2.5 dm3·ha-1), dicamba (Banvel 480 SL 0.5 dm3·ha-1), florasulam + 2,4D (Mustang 306 SE 0.6 dm3·ha-1), fluoroksypyr + 2,4D (Aminopielik Gold 530 EW 1.25 dm3·ha-1), mesotrione (Callisto 100 SC 1.5 dm3·ha-1), MCPA (Chwastox Extra 300 SL 3.0 dm3·ha-1), MCPA + dicamba (Chwastox Turbo 340 SL 2.0 dm3·ha-1), foramsulfuron + iodosulfuron methyl sodium (MaisTer 310 WG 0.15 kg·ha-1). Dual Gold 960 EC and Trophy 768 EC were applied directly after crop sowing and the other herbicides at the 3-4 leaf stage of sorghum. Weed control effectiveness was assessed 3-4 weeks after herbicide application. Before harvesting, the fresh weight of five sorghum plants and plant density were determined. The research indicated that years of experiments significantly influenced the herbicides selectivity. Fresh weight of 5 sorghum plants was significantly higher in comparison with the control plants after Trophy 786 EC (in 2006) and Chwastox Turbo 340 SL (in 2008) application, while sorghum density was influenced by Chwastox Turbo 340 SL (in 2006 and 2007) and Banvel 480 SL (in 2007). Maister 310 WG applied with adjuvant Actirob 842 EC caused the total destruction of sorghum.
