Effect of Kebar Grass (Biophytum petersianum) Extract on the Seminiferous Tubules in Male Mice (Mus musculus) Treated With 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)

| The aim of this research was to analyze the effect of kebar grass on the seminiferous tubules diameter and epithelium thickness of mice exposed to 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD). Twenty five BALB/C mice were used with five treatments (4 mice each group): Negative Control (C-), Positive Control (C+) with TCDD 7μg/kgBW IP, and treatment groups that treated with TCDD 7μg/kgBW IP and Kebar Grass orally for 53 days were presented T1 0,045mg/gBW/day, T2 0,080mg/gBW/day, and T3 0,135mg/gBW/day. Results showed that TCDD decreased the diameter and epithelium thickness of seminiferous tubules, while kebar grass extract was proven to maintain diameters but could not maintain epithelium thickness of of the seminiferous tubules.
Laboratory rearing, biology and chemical control of the mushroom sciarid Lycoriella auripila (Diptera: Lycoriidae)

SUMMARY The mushroom sciarid was found to develop on a plant-derived diet of oat or soya meal. Details of simple rearing techniques and insecticidal assays of treated casing are given. In laboratory tests using ten chemicals, chlorfenvinphos and pirimiphosethyl showed persistent activity against larvae when used at 15 ppm and are suggested as suitable for incorporation in peat-chalk casing mixtures to give protection throughout cropping. The low figures obtained for phytotoxicity and residues in the crop suggest this technique would be acceptable in commerce. Diazinon remained active in casing for only a short time.
Mitochondrial discordance in closely related Theridion spiders (Araneae, Theridiidae), with description of a new species of the T. melanurum group

The incorporation of molecular data into current taxonomic practise has unravelled instances of incongruence among different data sets. Here we report a case of mitochondrial discordance in cobweb spiders of the genus Theridion Walckenaer, 1805 from the Iberian Peninsula. Morphological examination of samples from a country-wide bioinventory initiative revealed the existence of a putative new species and two nominal species belonging to the Theridion melanurum species group. The morphological delineation was supported by the molecular analysis of a nuclear marker but was at odds with the groups circumscribed by a mitochondrial marker. The causes of this discordance remained uncertain, once sample and sequencing errors and the existence of pseudogenes were discarded. The full sorting observed in the alleles of the more slowly evolving nuclear marker ruled out incomplete lineage sorting, while the geographic patterns recovered were difficult to reconciliate with ongoing hybridization. We propose that the apparent incongruence observed is most likely the result of old introgression events in a group with high dispersal abilities. We further speculate that endosymbiont-driven cytoplasmatic incompatibility could be involved in the fixation of mitochondrial haplotypes across species barriers. Additionally, we describe the new species T. promiscuum sp. nov., based on the presence of diagnostic morphological traits, backed up by the nuclear data delimitation. Our study contributes yet another example of the perils of relying on single methods or data sources to summarise the variation generated by multiple processes acting through thousands of years of evolution and supports the key role of biological inventories in improving our knowledge of invertebrate biodiversity.
LIFE HISTORY VARIATIONS IN A PREDOMINANTLY GAMETOPHYTIC POPULATION OV IRIDAEA CORDATA (GIGARTINACEAE, RHODOPHYTA)1

An Iridaea cordata (Turner) Bory population made up of 83% gametophytes and 17% tetrasporophytes demonstrated little variation in these proportions over three years. These data contrast with an expectation that alternations of generations, as demonstrated by culture studies, should result in equal numbers of isomorphic generations. Analyses of reproductive and demographic attributes of the population were made to better understand the role of alternation of generations in this population.
Phytoavailability of Heavy Metals and Metalloids in Soils Irrigated with Wastewater, Akaki, Ethiopia: A Greenhouse Study

Irrigation with untreated wastewater from several industrial, commercial, and domestic discharges for decades caused accumulation of various heavy metals and metalloids in soils along the Akaki River in Ethiopia. Assessment of environmental threats and the potential phytoremediation of the soils require understanding of the toxic elements’ uptake and distribution in plant parts. Hence, a greenhouse study was performed to examine the phytoavailability and distribution of Cr, Ni, Co, Cu, Zn, Cd, Pb, Hg, Se, V, and As in forage grasses: Oat (Avena sativa), Rhodes grass (Chloris gayana), Setaria (Setaria sphacelata), and the legumes Alfalfa (Medicago sativa) and Desmodium (Desmodium unicinatum). The average contents of Cr, Ni, Co, Cu, Zn, Pb, Hg, Se, and V in the plants were generally higher than the background levels for forage grasses/legumes, and some of these elements were in the phytotoxic range. Root bioconcentration factor (BCF = root to soil concentration ratio) > 1 was observed for Cu (Oat, Rhodes, Desmodium, and Setaria: Fluvisol), Zn (Setaria: Fluvisol), Cd (Rhodes: Fluvisol; Setaria from both soils) and Hg (Oat and Alfalfa: Fluvisol). Alfalfa and Desmodium displayed translocation factor > 1 (TF = shoot to root concentration ratio) for most heavy metals. Most heavy metals/metalloids may pose a health threat to humans and stock via introduction to the food chain. The plant factors (species and plant part), soil factors (soil type, soil fractions, pH, and CEC), and their interactions significantly (p < 0.05) influenced plant heavy metal and metalloid levels. However, the role of plant part and species emerged as the most important on heavy metal uptake, translocation, sequestration, and ultimately transfer to the food chain. Accordingly, the uptake and distribution of heavy metals/metalloids in the plants reflect the potential environmental and health hazards attributable to the use of fodder grasses, legumes, and cultivation of vegetables in soils with polymetallic and metalloid contamination.
Patterns of seedling and overstory composition along a gradient of hurricane disturbance in an old-growth bottomland hardwood community

Disturbance patterns and species composition in the seedling and canopy layers were examined across the range of post-hurricane damage in an old-growth bottomland hardwood forest. Canopy coverage, tip-up number and area, snags, and coarse woody debris were quantified in plots along randomly oriented transects established in bottomland hardwood stands and mixed Pinus taeda L. - bottomland hardwood stands. Wilcoxon rank sum tests of these individual disturbance features indicated greater disturbance in plots containing the early successional species, Pinus taeda, than in mixed bottomland plots without it. Principal components analysis (PCA) using these features illustrated much overlap between the two assemblages and suggested a continuum of canopy and soil disturbance conditions from windthrows along axis I and a continuum of canopy disturbance due to snag formation along axis II. Woody seedlings and trees were inventoried in 30 plots spanning the range of disturbance. Seedling species richness exhibited a.
Relationship of soil properties and soil amendments to response of Glomus intraradices and soybeans

Knowledge of the role of soil properties on mycorrhizal relationships with host plants may contribute to the ecological understanding of the fungus and its effectiveness in indigenous or introduced soil conditions. This study examined the response of Glomus intraradices, an arbuscular mycorrhizal (AM) fungus, and soybean host in five benchmark soils. Glomus intraradices increased, with a few exceptions, shoot dry weight, root length, shoot phosphorus, and shoot zinc in all soils. Soil amendments (nitrogen, phosphorus, and pH adjustments) affected mycorrhizal hyphal length per plant and hyphal to root length ratio, as well as shoot Zn. Interactions among soil properties, soybean plant, and this mycorrhizal isolate suggested that soil properties, such as pH, pore diameter, and silt and organic matter, may have difficulties predicting arbuscular mycorrhizal fungal response. However, before soil amendment, regression models were accurate in predicting shoot dry weight, mycorrhizal colonization, and hyphal dev.
Generation V: Millennial Vegans in Israel

This study asks how and why veganism becomes a way of constructing generational identities and worldviews. Focusing on Israeli millennial vegans, I argue that veganism enables millennials to constitute a generational mode of thought that differentiates them from preceding generations through three interrelated practices: replacing evidence-based knowledge with other types of information, based on personal experience and consensual agreement among peers; constructing an Israeli identity that shifts commitment from national issues to global ones; and establishing spaces of consumption that operate according to marketing strategies meant to socialize practitioners into becoming critical consumers while participating in a young urban lifestyle. All of these position veganism as a means by which millennials exert control where they can, in an increasingly complex world, while refraining from challenging the political and economic systems.
Wild Oat (Avena Fatua) vs. Redstem Filaree (Erodium Cicutarium) Interference in Dry Pea

Dry peas (pea) usually require early and effective weed management for optimum yields. However, it is not always possible to control all weeds with a single herbicide application. In experiments at Lacombe and Lethbridge, Alberta, Canada, we determined the relative importance of controlling redstem filaree or wild oat, or both species. Bentazon, sethoxydim, or a imazethapyr/imazamox mixture was applied to control redstem filaree, wild oat, or both weeds, respectively. None of the herbicides caused visually detectable crop injury. Time of weed removal effects on pea yield were inconsistent. In addition, applying half or full herbicide rates did not usually influence weed biomass, pea yield, or pea seed weight. Averaged across all variables except herbicide, pea yield losses due to competition from redstem filaree, wild oat, or both species averaged 31, 47, or 53%, respectively. When redstem filaree and wild oat were controlled with imazethapyr/imazamox, pea yields were the same as weed-free check plots in three of four location-years (89% of weed-free yields for all four location-years). Optimal pea yields in weed communities with redstem filaree and wild oat as dominant species were more dependent upon selecting an herbicide that controlled both species than a specific time of weed removal or herbicide rate.

HABITAT AND AREA EFFECTS ON FOREST BIRD ASSEMBLAGES: IS NEST PREDATION AN INFLUENCE?

The ability of nest predation to explain patterns of covariation in species numbers with area and habitat was examined for forest birds. Numbers of individuals and species of birds were counted in 23 drainages in high elevation (2300 m) forest in central Arizona for 3 yr. Variation in bird species numbers was compared to variation in area and habitat structure among drainages. Birds were grouped into foraging (bark, understory foliage, canopy foliage, aerial) and nesting (cavity, understory foliage, canopy foliage) guilds based on heights and substrates used. Numbers of species increased with area for all guilds, but species-area slopes differed among nesting guilds. Differences in slopes cannot be explained by passive sampling because source pool size was the same or similar between guilds compared. Differences in slopes are consistent with a prediction that slopes should be greater for guilds that are more susceptible to nest predation. Variation in numbers of species among drainages was positively correlated with variation in the density of foraging and nesting substrates. However, correlations were greater when based on nesting than foraging heights and substrates. The results are consistent with a prediction that birds are selecting habitat sites based in part on the availability of nest sites that minimize risk of nest predation, and that these nest sites increase with density of foliage at nest height. These results are also consistent with a hypothesis that availability of suitable nest sites is one of the bases for the relationship between species numbers and foliage density for foliage-nesting species. This conclusion is supported by a re-analysis of the data of Willson (1974), where foliage-nesting birds were grouped into nest-height guilds using data from the Cornell Nest Record Program; more of the birds that were added with vegetation layers tended to nest in those layers than forage in them. In short, multiple activities (foraging and nesting) can allow multiple processes to act simultaneously.
The Relationship Between Campus Recreation Facility Use and Retention for First-Time Undergraduate Students

This study examines the relationship between campus recreation facility access and first-year retention of full-time, first-time undergraduate students at a public university for 2014–2015 through 2016–2017. Authors examine differences between facility users and nonusers by pairing facility swipe card data with student records. Statistical analysis includes logistic regression and matching approaches, controlling for student demographics, academic preparedness, academic goals, family characteristics, and various environmental factors. Results show a positive and significant relationship between recreation facility use and retention, including 7.1 to 8.4 percentage points higher retention for users versus nonusers, holding other variables constant. Subsample analysis suggests the relationship between recreation facility use and retention differs across student subgroups. Key study contributions include linking card swipe data on facility usage with extensive student records, clearly defining facility users and nonusers, and introducing a new robustness check based on assignment of students to residence halls different distances from recreation facilities.
Observations on Microalgae in Supralittoral Rockpools in New England (USA)

Microalgae may reach very high concentrations in rockpools above the high tide level at the Isles of Shoals (New Hampshire/Maine). Observations on green algae in several representative pools in 1975 and 1978 indicated factors important in controlling algal abundance in pools. Algae tolerated relatively wide fluctuations in salinity and did not appear to be limited or inhibited by nutrients. Population declines were associated with major changes in salinity and grazing by ciliates and invertebrates. Since populations in a pool did not appear to interact strongly, it is probable that each population was largely self-regulating and could maintain a relatively constant size for extended periods of time.
EFFECT OF SEASON ON BOAR SPERM MORPHOLOGY

The objective of this study was to analyze the influence of the year–season effect on semen production parameters in the fertile AI boars. The evaluation was especially focused on the morphologically abnormal spermatozoa (MAS) incidence. It was microscopically evaluated after making fresh semen smears and staining on microscopic slides. MAS incidence 19.46 % was lower at first half-year than at second half-year 25.00 % (P<0.01). Spermatozoa with distal protoplasmic droplet were furthest participated in total MAS incidence. Its rate was the highest at fourth quarter in comparison with annual period (P<0.001). We found that season has the negative effect on sperm morphology and significantly affects boar sperm quality and subsequently AI dose quality.
Computing Professionals for Social Responsibility: The Past, Present and Future Values of Participatory Design

Values play a central role in technology design. But beyond acknowledging the politics of technology, questions remain around where those values are coming from, which values we need, and how they play out and shape the socio-technical systems we create. New challenges such as the climate crisis and societal polarization call for technologists to become part of the public and political arena. This results in a new sense of responsibility, but the closing of CPSR, the Computing Professionals for Social Responsibility, has left a gap. Today, across tech workers, academics and computing professionals, there is a renewed sense of urgency for engaging the public and politics to change course in how computing shapes society. What should a CPSR for the 21st century look like? This interactive workshop aims to re-invigorate the debate around values and social responsibility in Participatory Design with special attention to the Latin American context.

Mediating Role of Prosocial Motivation in Predicting Social Entrepreneurial Intentions

Abstract The aim of this research study to identify the role of empathy, moral judgement and social entrepreneurial education in predicting social entrepreneurial intention. And also test the mediating effect of prosocial motivation in this relationship. Through the survey, primary sample data of 755 nascent social entrepreneurs were used to test the hypotheses. The hypothesised moderated mediation condition was supported as results suggest that prosocial motivation mediated the relationship between antecedents and social entrepreneurial intentions. Besides this social entrepreneurial education showed a strong direct relationship with social entrepreneurial intentions. These findings strengthen the argument which states that there is a great need from policy, educators and universities to start courses that can imbibe the feeling of empathy. And also support system to motivates students to go for social entrepreneurship as a career choice.
Hypoxia tolerance of European sturgeon (Acipenser sturio L., 1758) young stages at two temperatures

Summary European sturgeon sensitivity to oxygen depletion at two different temperatures was evaluated with embryos from fertilization to hatching time that were exposed to 90% O2 saturation (% O2 sat), 50% O2 sat and 30% O2 sat at 20 and 26°C; and three-month-old juveniles (12 cm length, 7.3 g width) exposed to oxygen challenge from 70% O2 sat to 10% O2 sat at 20 and 25°C. Parameters measured included embryonic survival rate (ESR) and hatch rate (HR); in juveniles the opercular beat frequency (OBF), altered swimming behavior, loss of equilibrium (LOE), and death were recorded. ESR did not differ between oxygen saturation levels for a single temperature but decreased between 20 and 26°C from 60.7 to 21.4% mean survival, respectively. No hatching was observed in embryos exposed to oxygen depletion at 50 and 30% O2 sat, regardless of temperature. The HR was lower at 26°C (15.4% mean) than at 20°C (75.8%) at 90% O2 sat. In embryos, all three oxygen concentrations allowed embryonic survival at the tested temperatures but were insufficient for increased activity such as hatching except at 20°C and 90% O2 sat. In juveniles, OBF peaked at 40% O2 sat at 212 beats per minute at 25°C and at 40–30% O2 sat at 182–183 beats per minute at 20°C. For LOE and death no significant differences were observed with regard to oxygen saturation at 20 and 25°C. Altered swimming behavior appeared at a significantly higher oxygen saturation at 25°C (43.5%) compared to 20°C (34.5%). Anaerobic metabolism was initiated after the OBF peak, which would represent a PO2crit for European sturgeon juveniles under 30 and 40% at 20°C and 25°C, respectively. Temperature increase also adversely affected the threshold of altered swimming behavior, which could be considered as a behavioral indicator of metabolic stress. The probability that the sturgeon embryos are being exposed to harmful temperatures and hypoxic conditions remains a true threat in the Gironde catchment basin.
Missed Opportunities for Human Immunodeficiency Virus (HIV) Testing During Injection Drug Use-Related Healthcare Encounters Among a Cohort of Persons Who Inject Drugs With HIV Diagnosed During an Outbreak-Cincinnati/Northern Kentucky, 2017-2018.

BACKGROUND Persons who inject drugs (PWID) have frequent healthcare encounters related to their injection drug use (IDU) but are often not tested for human immunodeficiency virus (HIV). We sought to quantify missed opportunities for HIV testing during an HIV outbreak among PWID. METHODS PWID with HIV diagnosed in 5 Cincinnati/Northern Kentucky counties during January 2017-September 2018 who had ≥1 encounter 12 months prior to HIV diagnosis in 1 of 2 Cincinnati/Northern Kentucky area healthcare systems were included in the analysis. HIV testing and encounter data were abstracted from electronic health records. A missed opportunity for HIV testing was defined as an encounter for an IDU-related condition where an HIV test was not performed and had not been performed in the prior 12 months. RESULTS Among 109 PWID with HIV diagnosed who had ≥1 healthcare encounter, 75 (68.8%) had ≥1 IDU-related encounters in the 12 months before HIV diagnosis. These 75 PWID had 169 IDU-related encounters of which 86 (50.9%) were missed opportunities for HIV testing and occurred among 46 (42.2%) PWID. Most IDU-related encounters occurred in the emergency department (118/169; 69.8%). Using multivariable generalized estimating equations, HIV testing was more likely in inpatient compared with emergency department encounters (adjusted relative risk [RR], 2.72; 95% confidence interval [CI], 1.70-4.33) and at the healthcare system receiving funding for emergency department HIV testing (adjusted RR, 1.76; 95% CI, 1.10-2.82). CONCLUSIONS PWID have frequent IDU-related encounters in emergency departments. Enhanced HIV screening of PWID in these settings can facilitate earlier diagnosis and improve outbreak response.
