Menstrual equity in Canada - Current knowledge and future research directions: Literature review
No full textThe following report, prepared for Women and Gender Equality Canada (WAGE), provides a review of literature reflecting current knowledge about menstrual equity, the extent of period poverty in Canada and future research directions. The report also includes a summary overview of key terms and concepts, frameworks and context factors relevant to the present study. Analysis was guided by the PROGRESS-Plus approach (1), which serves to ensure an equity lens in research. The current report is one of three submitted to WAGE: Literature review, Qualitative research, and High-level environmental scan. Research examining menstruation, the menstrual cycle and the lived experiences of menstruators has been historically marginalized (2). Recent years have seen a proliferation of research and literature; however, primarily within global public health or countries outside Canada (3). Here in Canada, we are just beginning to understand the differential impacts of period poverty on vulnerable and marginalized groups, as well as the range of systemic factors that shape menstrual inequities. Existing Canadian scholarly and grey publications reflect the nascent character of menstrual equity knowledge in Canada, while acknowledging the importance of key frameworks for directing future research.Menstrual Research Grou
The Investigation of residential architecture in the Bronze Age. Tape Yal, Sistan and Baluchestan province, Iran
No full textThe first villages were formed during the Neolithic period, when people began building residential architecture. Villages continued to exist in Iran until the 2nd half of the 4th millennium BC, when the first cities appeared. Settlement in Shahr-i Sokhta had begun during this period, and in the 3rd millennium BC, the city’s size expanded and many related-settlement sites were formed in the Sistan plain. A prominent related-settlement site of Shahr-i Sokhta is Tape Yal or Taleb Khan 2, located 11 kilometres from the city. An excavation was conducted at this site by one of the author. This article analyses the architectural features of this site, a Bronze Age village of the Hirmand civilization, based on the findings of this excavation. It has been determined that this site contains residential buildings, workshops, and storage rooms with mudbrick construction. The above residential buildings probably belonged to the craftsmen of this village who lived next to their workshops.The first villages were formed during the Neolithic period, when people began building residential architecture.

Visible Light-Driven Synthesis of a Bioinspired Porphyrin-Based Polymer-Coated MOF for Efficient and Selective Photocatalytic Oxidation of Vanillyl Alcohol to Vanillin
No full text[EN] The development of metal-organic framework (MOF)-polymer composites presents a promising avenue for designing advanced functional materials, yet preserving MOF porosity and stability after modification remains challenging. Here, the study synthesizes a MOF from cost-effective precursors under mild conditions and functionalizes it in situ covalent porphyrinic polymer layer via visible-light irradiation, eliminating the need for additional reagents. The resulting composite, CPhP@UiO-66(Ce)-NH2, is extensively characterized using FT-IR, XRD, SEM/EDX, HRTEM, BET, XPS, UV-vis DRS, EPR, transient absorption spectroscopy, and solid-state 13C NMR spectroscopy. Under low-energy LED light, the composite efficiently generates reactive oxygen species (ROS), enabling the additive-free aerobic oxidation of vanillyl alcohol (a lignin model monomer) to vanillin with high selectivity and conversion, outperforming both the parent MOF and reported systems. This work introduces a novel, biomimetic strategy for constructing macrocycle-inspired MOF-polymer hybrids, demonstrated for the first time in selective photocatalytic aerobic oxidation. The findings advance the design of MOF-based materials for sustainable catalysis and green chemistry applications.Financial support was provided by UEFISCD, Ministry of Innovation and Science (Severo Ochoa CEX2021-001230-S and PDI2021-0126071-OB-CO2, both funded by MCIN/AEI/10.13039/501100011033), Generalitat Valenciana (Prometeo 2021-38 and Advanced Materials Programme Graphica MFA/2022/023 with funding from the European Union NextGenerationEU PRTR-C17.I1) are gratefully acknowledged.

COMPETITIVE HIERARCHY OF TWO RAGWEED SPECIES AND ITS EFFECT ON OTHER WEEDS IN THE PLANT COMMUNITY
No full textAmbrosia artemisiifolia (AMBEL) and Ambrosia trifida (AMBTR) are recognized as troublesome invasive plant species in several regions of the world, including Europe. Under their impact, crop production is reduced in the invaded areas, and a large amount of pollen produced is harmful to human health. The height and density of these species can produce strong shading effects and inhibit the growth of other species, which is a precondition significantly changing the biodiversity and structure of the invaded ecosystems. Unlike AMBEL, which is widespread in many parts of Serbia, AMBTR is currently naturalized only in the area of central Bačka. Their harmful impact has also been noted in this area. Given all the above, the aim of this research was focused on examining the interaction of two ragweed species and their impact on other species in the plant community. During 2016 and 2017, field experiments were carried out at a farm near Dobrić, Republic of Serbia (44°41′N, 19°34′E). Unlike AMBEL, which forms dense populations in this area and greatly impacts crop production, AMBTR has not yet been recorded in this part of Serbia. Seeds of AMBTR were collected in autumn 2015 from infested crop fields in Central Bačka (45°30′N, 19°31′E). The experiment was set up as a replacement series design (four replicates) in different AMBEL/AMBTR ratios per m2: 10/0; 8/2; 6/4; 4/6; 2/8; 0/10. In addition to maintaining the total number of ragweed/m2, other weed species were not removed. They were more or less homogeneously distributed, with the most abundant species being Setaria viridis, Echinochloa crus-galli, Sorghum halepense, Polygonum aviculare, Cirsium arvense, Chenopodium album, Plantago major, and Erigeron annuus. The dry mass of plants was measured to assess interactions, and data analysis was performed in R-studio. During both seasons, ANOVA showed the same trend. With the increase in the number of AMBTR/m2 and the decrease in the number of AMBEL/m2, the dry mass of AMBTR decreased. Opposite, with the increase in the number of AMBEL and the decrease in AMBTR, the dry mass of AMBEL was increasing. According to the results, it can be concluded that interspecific competition is larger for AMBEL, in contrast, intraspecific is greater for AMBTR. During both seasons, in the treatments with the increase in the number of AMBTR and the decrease in the number of AMBEL/m2, the dry mass of other weeds decreased. Additionally, we conclude that AMBTR had a greater impact on other weeds in the plant community
Crop rotation influence on vertical weed seed bank
No full textSoil weed seed bank represents a latent plant community, so, the knowledge of vertical distribution and number of seeds in soil profile is one of the reliable ways to prepare the adequate weed control strategy. It is believed that the crop rotation is one of the most important agrotechnical measures which, in interaction with weed control, impact both size and composition of the weed seed bank. In a long-term stationary experiment “Plodoredi” at the Institute of Field and Vegetable Crops, Novi Sad, Serbia (N 45° 19', E 19° 50') a weed seed bank in wheat monoculture, two year crop rotation (winter wheat – maize) and three year crop rotation (winter wheat – soybean – maize) has been estimated. Based on a three-year successive soil sampling in depth of 0–15, 15–30 and 30–40 cm and by applying the method of physical extraction of seed it has been established that in all three crop systems the seeds are distributed in the way that the layer of 0-15 cm had most seeds. The abundance decreased gradually with the increase in depth
Effect Long-Term Management System on Soil Weed Seed Bank
No full textLong-term monoculture has a de-stroying impact on plant production, while crop rotation is known as a more eco-friendly approach as provides diversification in crop management systems, modifies intensive pressure on the agricultural ecosystem, utilizes various soil horizons, and prevents the establishment of specific pests and weeds. The aim of his research was to answer: How management system over 50 years of specific continuous crop management programs (crop rotation and fertilization) effect on weed populations? This study was conducted in the experimental site of the Institute of Field and Vegetable Crops of “Plodoredi”, Rimski Šančevi,
Novi Sad, Serbia
Weed seed bank model
No full textWeed seed banks are an inexhaustible and permanent source of weeds, but they also have a stabilizing effect on the ecosystem and biodiversity in plant production systems. Scarce rese-arch on this topic has shown great variability in results, in part, due to different methodology of the seedbank estimation. The aim of this research was to compare two methods of estimating weed seed bank: 1) physical extraction of seeds, and 2) seedling emergence method. The plo¬ts of the stationary experiment "Plodoredi", Institute of Field and Vegetable Crops, Novi Sad, Serbia (N 45° 19', E 19° 50') were used for these research. Soil samples were taken from two experiments, a 50-year winter wheat monoculture, and from a three-year crop rotation (winter wheat-maize-soybean), over the course of three years (2014-2017). The method of physical extraction, although longer and physically more exhaustive, showed better results. In winter wheat monoculture 12 weed species were recorded, with a total of 21575 seeds m-2, while in the three-year crop rotation 25 weed species were detected, with a total of 16300 seeds m-2. Using the seedling emergence method only five weed species and 8500 seeds m-2 were estimated in monoculture, while in crop rotation five weed species and 4500 seed m-2 were estimated. This indicates that the entire weed seed bank is not active: some seeds are not able to germinate, while others are dormant, but present a potential danger. The estimated number of seeds per m-2 by the more efficient method of physical extraction was used to create the “Artificial Neural Network’’ model which had been previously tested using the Random-Holback method. The model answered the key question: how monoculture and crop rotations can change the soil weed-seed bank and diversity in a long-term cropping system
