Relevance. In the conditions of the Central Black Earth region in the farm “Yaroslav the Wise” of the Starooskolsky district of the Belgorod region, five soybean varieties (Belgorodskaya 48, Bara, Victoria, Opus and Kassidi) were studied on nutritional backgrounds — without seed inoculation and without biological treatment (control), using only inoculation and with the use of a biological product against the background of seed inoculation.Methods. The experimental conditions differed in rainfall patterns and the amount of heat, their distribution was especially uneven in 2020, that had a significant negative effect on the yield of all studied soybean varieties. The soil of the experimental plot is typical medium-thick chernozem, medium-humus, heavy loamy texture. The advantages of the soybean variety Opus, the plants of which formed a large height, air-dry mass, leaf area, a greater number and mass of nitrogen-fixing nodules on the roots, were revealed. Plants of this variety provided a higher yield level in all studied agro-backgrounds.Results. The yield varied from 32,5 centners per hectare (control) to 36,2 centners per hectare (when using the biological product Biogor, Zh). The content and collection of protein were also higher in the Opus cultivar in all the studied agrophones. In comparison with the control, the protein content was higher by 4% (background — control), by 4,9% — with inoculation of seeds and by 6,1% — when using a biological product. The same pattern is observed when assessing the oil content in seeds and collecting protein and oil per hectare of soybean sowing. Inoculation of seeds with soybean inoculant Nitragin, KM improved plant development and increased productivity, as well as the profitability of cultivation of the studied soybean varieties, which was higher when using a biological product against the background of seed inoculation by an average of 27%, while with only inoculation — by only 15,1%.

Pintomyia evansi is recognized by its vectorial competence in the transmission of parasites that cause fatal visceral leishmaniasis in rural and urban environments of the Caribbean coast of Colombia. The effect on and the variation of the gut microbiota in female P. evansi infected with Leishmania infantum were evaluated under experimental conditions using 16S rRNA Illumina MiSeq sequencing. In the coinfection assay with L. infantum, 96.8% of the midgut microbial population was composed mainly of Proteobacteria (71.0%), followed by Cyanobacteria (20.4%), Actinobacteria (2.7%), and Firmicutes (2.7%). In insect controls (uninfected with L. infantum) that were treated or not with antibiotics, Ralstonia was reported to have high relative abundance (55.1–64.8%), in contrast to guts with a high load of infection from L. infantum (23.4–35.9%). ASVs that moderately increased in guts infected with Leishmania were Bacillus and Aeromonas. Kruskal–Wallis nonparametric variance statistical inference showed statistically significant intergroup differences in the guts of P. evansi infected and uninfected with L. infantum (p < 0.05), suggesting that some individuals of the microbiota could induce or restrict Leishmania infection. This assay also showed a negative effect of the antibiotic treatment and L. infantum infection on the gut microbiota diversity. Endosymbionts, such as Microsporidia infections (<2%), were more often associated with guts without Leishmania infection, whereas Arsenophonus was only found in guts with a high load of Leishmania infection and treated with antibiotics. Finally, this is the first report that showed the potential role of intestinal microbiota in natural populations of P. evansi in susceptibility to L. infantum infection.

In order to determine the effect of cultivars and planting date on flax fatty acid profile, seed yield, and oil content, an assay with seven cultivars (Baikal, Prointa Lucero, Prointa Ceibal, Panambí INTA, Curundú INTA, Carapé INTA, and Tape INTA) was carried out at Parana Agricultural Experimental Station, Argentina. Significant differences among cultivars were found for content of palmitic (5–7 g/100 g), stearic (5–8 g/100 g), linoleic (13–19 g/100 g), saturated (11–15 g/100 g), and unsaturated acids (92–96 g/100 g) within the seven cultivars. The best seed yields were observed in Prointa Lucero and Carapé INTA varieties (2091.50 kg·ha−1and 2183.34 kg·ha−1, respectively) in the first planting date and in Carapé INTA and Prointa Lucero (1667 kg·ha−1and 1886 kg·ha−1, respectively) in the second planting date. A delayed planting date had a negative effect on seed yield (1950 kg·ha−1and 1516 kg·ha−1) and oil content (845 kg·ha−1and 644 kg·ha−1) but did not affect oil composition.

The cultivation of small fruits has been increasing with good economic returns, and among these, the genus Physalis has been an important alternative source of income due to the high value and possibility of cultivation in small areas. However, there is not established fertilization for this crop and considering that nitrogen is one of the most limiting nutrients for the growth and development of plants, this study aimed to evaluate the agronomic aspects of two species of Physalis submitted to different N doses. The experiment was conducted in a greenhouse in a completely randomized design, using two species (Physalis pubescens and P. peruviana) and five N doses (0, 200, 250, 300 and 350 kg ha-1), and seven replications. The plant height, dry mass of aerial part and roots, the number of branches, root length, yield and average fruit mass were evaluated. In these experimental conditions, it was observed that for P. peruviana the dose of 250 kg ha-1 N resulted in a greater yield of fruit per plant, as for P. pubescens the dose of 350 kg ha-1 N showed a more efficient performance.

Chia (Salvia hispanica L.) is an herbaceous annual plant considered a natural source of Omega 3 and 6 fatty acids, fiber, protein and antioxidants. However, the cultivation in Brazil is still recent and existing technical information and recommendations are limited, especially regarding to fertilization and sowing season. The present work had as objective to evaluate the effect doses application of phosphorus and sowing times over productive and reproductive parameters. The experiment was conducted in greenhouse conditions at Fazenda da Universidade Estadual de Maringa, Campus Umuarama. The soil used for the experiment is a typical Distrofic Red Latosoil, with sandy texture. The experimental design was entirely in factorial scheme 4 &times; 4 with three replications. Treatments were composed of four seeding seasons, at intervals of 15 days between one and another with four doses of P2O5 applied at seeding (0, 40, 80 and 120 kg ha-1, totalizing 48 plots units. It was evaluated the following parameters dry mass of root and shoot, grain yield, mass of 1,000 grains and oil content. There were no significant results both for phosphorus doses as for interaction in any of the variables evaluated. The treatment seeding times (E) differed statistically only for grain yield.

The research was made for quantification the interaction between cultivating variety –fertilized-planting distance between rows at the oilseed rape in the favorable pedoclimatic conditions for rape on the Vest Plain where can be obtained the highest productions. In this way, was studied to the influence of the fertilization upon the productions, at an assortment of seven rape varieties. The researched biological material was formed of seven rape varieties new for the reference area, as follows: Valesca, Orkane, Ader, Potomac, LG, Belini, Milena. To point the negative effect of the nitrogen fertilization, to optimize the doses upon the productions, was accounted the agrofond dose, in domain N0-N225. The research was made on a fund of P80 K80, so that varieties can expose their productive potential and the specific oil content. The results obtained accentuated the fact that the seven rape varieties studied, in the fertilization domain N0-N225, In average on the 4 agrofonds and the two distances between the rows, it resulted that in the researched area the most appropriate is Valesca variety, on which the harvest exceeded 2800 kg/ha. Varieties Milena, Potomac and Orkane registered harvests of over 2200 kg/ha. Yield increases obtained for the varieties fertilized with nitrogen at all doses level, are very significant. Distance between rows, represents a technological element studied in all the countries that cultivates autumn rapeseed. The results obtained in the experimental cycle, regarding this aspect, leads to the conclusion that for the studied varieties, a distance between 12,5 and 25 cm, ensures an harvest increase the exceeds 300 kg/ha. The researches results are important for the growers, because they increase the possibility to obtain productions higher than 3700 kg/ha.

48 college freshmen volunteered for this investigation and were assigned to one of four experimental conditions: sensory reduction plus message, sensory reduction only, message only, or no treatment control. All subjects rated their own personalities using a modified form of the Brownfain Self-rating Inventory one day prior to and immediately following the experimental treatment. The duration of the stimulus reduction experience was 40 min. and the taped message was designed to enhance self-concept. Results indicated that the sensory reduction inhibited the enhancement of self-concept, whereas subjects who were presented the taped message in a normal sensory environment showed a significant enhancement of self-concept. It was hypothesized that the sensory reduction created a high level of anxiety which served to interfere with the effectiveness of the stimulus tape.

Temperature Storage

This paper investigates the change in performance of DMFC membrane electrode assemblies (MEAs) after storage at −10°C and 60°C under different experimental conditions. It highlights the importance of methanol concentration, an MEA’s material properties such as membrane material and catalyst loading, as well as the reactivation procedure. Storage at 60°C and concentrations below 1M methanol had no negative effect on MEA performance while storage at 60°C in a 4 M methanol solution could cause a severe performance decrease. Application of a reverse current for 10 s to a MEA which was affected by such storage was found to reinstall original performance. The effect of storage at −10°C on MEA performance strongly depends on MEA properties. MEAs are grouped into three different categories with regard to suitability for low temperature storage: not affected, reversibly affected, and irreversibly affected. The reversibly affected MEAs could be instantly and completely reactivated by reverse current. MEA materials such as various hydrocarbon membranes and high catalyst loadings as well as the manufacturing methods CCM (catalyst coated on the membrane) and CCS (catalyst coated on the substrate) were found to be principally suitable to build MEAs tolerant to storage at −10° C.

Advanced oxidation processes (AOPs) composed of O3, H2O2 and ultraviolet (UV) were applied to degrade tetracycline (TC). Degradation efficiency was evaluated in terms of changes in absorbance (ABS) and total organic carbon (TOC). The change in biotoxicity was monitored with Escherichia coli and Vibrio fischeri. The improvement in biodegradability during oxidation was demonstrated through 5-day biochemical oxygen demand/chemical oxygen demand ratio and aerobic biological treatment. The combination of O3/H2O2/UV and O3/UV showed the best performance for the reductions in ABS and TOC. However, mineralization and detoxification were not perfect under the experimental conditions that were used in this study. Therefore, for the ultimate treatment of TC compounds, it is suggested that AOP treatment is followed by biological treatment, utilizing enhanced biodegradability. In this study, aerobic biological treatment by Pseudomonas putida was performed for O3/UV-treated TC. It was confirmed that O3/UV treatment improved TOC reduction and facilitated complete mineralization in biological treatment.

Objectives The hypoalgesic effect of electroacupuncture (EA) was directly compared with the analgesic effect of pharmacological interventions using the submaximum effort tourniquet technique (SETT). Methods 125 healthy subjects (mean age 24.44±4.46 years; 62.4% female, 37.6% male) performed SETT at baseline and under one of five experimental conditions (n=25 per group): EA (2 Hz with burst pulses in alternating one-phase-square wave pulses; burst length 180 μs, burst frequency 80 Hz, stimulation time/pulse width 3 s), tramadol (50 mg), ibuprofen (400 mg), placebo pill or non-treatment control. EA was performed at LI4 and LI10 contralaterally with stimulation beginning 20 min before SETT and lasting throughout SETT. The pharmacological interventions were given in a double-blind design 1 h before the SETT assessment. Results Subjects showed a hypoalgesic effect of the opiate and of the EA for subjective pain rating (EA p=0.0051; tramadol p=0.0299), and pain tolerance index (time/rating) (EA p=0.043; tramadol p=0.047) analysed using analysis of covariance. More subjects reached the strict time limit of 30 min (analysed by logistic regression and adjusted OR as a post-hoc analysis) under EA compared with most other experimental conditions. Only EA and tramadol were not significantly different (95% Wald confidence limits: non-treatment control vs EA 0.011 to 0.542; placebo pill vs EA 0.009 to 0.438; ibuprofen vs EA 0.021 to 0.766; tramadol vs EA 0.065 to 1.436). Conclusion In a laboratory setting, an EA procedure was as effective as a single dose of an orally administered opiate in reducing experimentally induced ischaemic pain.

The effect of four different irrigation intervals, 7, 14, 21 and 28 days, on the avocado tree was tested during the years 1968–1974 in the northern coastal plain of Israel. The respective average annual water applications were 8890, 7450, 6680 and 5940 m3/ha. The cultivars Ettinger, Fuerte and Hass were tested in five replications in randomized blocks. After 6 years no significant reduction in yield was observed with Ettinger or Fuerte trees irrigated once in 21 or 28 days. With the Hass cultivar the 28-day interval gave lower yields than with the three other intervals tested. Shortening of irrigation intervals increased the growth rate and size of individual fruits, which may be of economic importance for cv. Hass, where overproduction leads to small fruits unsuitable for export. Shortening of irrigation intervals tended to increase the oil percentage of the fruit, which may advance the harvest date. In view of the equal yields obtained and the predominance of cv. Hass in avocado plantations, it was concluded that the 21-day interval was the optimum irrigation frequency under the experimental conditions. __________________ *Part I, Aust. J. Agric.
