Peat flows, bog flows, or bog bursts consist of a rapid downhill movement of masses of saturated peat. Although this process has been documented from peatlands in other parts of the world, the slope movement described here is the first to be reported from Canadian peatlands. The peat flow took place on the east coast of Kaien Island, near Prince Rupert, British Columbia, and was initiated by a slump in a peat spoil pile. It involved the sudden mobilization of a strip of in situ peat 210 m long and approximately 20 m wide. The peat was fibrous, rich in roots, and had a moisture content of approximately 240%. The flow demonstrates the high potential mobility of natural peat covers and the role of undrained loading in effecting movement of slopes as low as 5°. Key words: peat, flow slide, peat flow, northeast British Columbia.

Fulvia fulva, the agent of leaf mould, is known to be a major parasite of tomato leaves in greenhouses. Its development is characterized by a biotrophic phase followed by a necrotrophic phase. Hansfordia pulvinata is a hyperparasite of this pathogen, but its destructive action is restricted by its inability to colonize F. fulva during the biotrophic phase, before lesion formation. An integrated system to optimize the mycoparasitic activity of H. pulvinata was studied. The hyperparasite was tolerant to fosetyl-Al in situ. At a minimal concentration of 500 mg/L, the fungicide inhibited F. fulva spore germination after spraying on tomato leaves but did not have any effect during the necrotrophic phase. Thus, fosetyl-Al, which prevented reinfection, and the destructive hyperparasite H. pulvinata had complementary effects. Key words: Hansfordia pulvinata, fosetyl-Al, Fulvia fulva, integrated control, leaf mould, tomato.

Emission Changes

The COVID-19 pandemic resulted in changed emission regimes all over the world. India also imposed complete lockdown on all modes of travel and industrial activities for about 2 months from 25-March-2020 and later unlocked these activities in a phased manner. Here, we study signatures of emissions changes on levels of atmospheric trace gases and aerosols contributing to air pollution over multiple sites in India’s capital Delhi covering various lockdown and unlock phases using satellite data and in-situ observations. The resulting changes in the levels of these species were compared with respect to their average of 2015–2019 to attribute for year to year and seasonal changes. A clear impact of lockdown was observed for AOD, PM, NO2, CO, and SO2 as a result of emission changes, while changed precursor levels led to a change in O3 chemical regimes impacting its concentrations. A detailed analysis of FLEXPART trajectories revealed increased PM levels over Delhi in north-westerly air masses sourced to Punjab region all the way up to Pakistan. Changes in aerosols and NO2 were not only restricted to the surface but transcended the total tropospheric column. The maximum decrease in PM, NO2, CO, and SO2 was observed during the month of total lockdown in April. The lockdown impact varied with species e.g., PM10 and PM2.5 as well as locations even within the periphery of Delhi. While surface level aerosols and NO2 showed significant and almost similar changes, AOD showed much lower decrease than tropospheric column NO2.

Since the evolution of mankind, the need for food and drink has been a major concern for humans. It has been reported from the ancient records that human had to cultivate and the store food for consumption but as time passed humans started to travel from one place to another in search of food and drink which further in the modern era gave rise to the tourism sector where people travel for one place to another to explore new culture and experience the local cuisine which depicts about the place and its community living around the region. Due to this, there was a tremendous increase in the percentage of tourists every year in different continents where they only travel for leisure and availing the local cuisine that included both food and the local beverage of the location. Therefore, the essence of food is also a vital part of the lifestyle for every individual and tourists who travel to the destination and try to experience the local cuisine. If you see the world, most of the tourists are eagerly mad at traveling to India, wherein every 100 meters you will get a varied cuisine influence which fascinates the international tourists towards the country's culinary inheritance. Therefore, the role of promotion and marketing of the regional cuisine of a country as it showcases the cultural identity of the nation's heritage. Henceforth, the paper explores the framework of the tasting tourism as to create a new phase of tourism after the Covid-19 in order to increase the tourism sector by introducing a new segment where the cuisine will showcase the opportunity for providing an extensive knowledge for the regional cuisine and beverages available, where they can experience during their travel to the region. But due to the pandemic situation, it has been seen that the Indian tourism sector had a drastic change as the inflow of foreign tourists decreased, and also the food business sector is facing downfall due to the rapid spread of the virus.  Key words: Gastronomy; Tasting Tourism; Indian cuisine; Marketing; Promotion; Tourists.

Ruminal Degradability

High-moisture barley (HMB) was ensiled in polyethylene silage bags. Treatments applied to 30% moisture HMB as a percentage of dry matter (DM) were: none, 1% ammonia, 2% ammonia, and 1.5% sulphur dioxide. A fifth treatment was the addition of 1.5% sulphur dioxide to 20% moisture HMB. Barley samples were ruminally incubated to estimate degradability of DM and nitrogen (N). Ruminally incubated bags were also introduced to the duodenal cannulae and collected in feces to estimate true whole-tract digestion. Sulphur dioxide treatment, or moisture content, had no influence on ruminal degradability, with the exception of increased degradation rate of potentially degradable N for 20 vs 30% HMB, or whole-tract true digestion. Ammoniation resulted in net reduction in rate of ruminal DM release due to shift of soluble DM to the potentially degradable fraction, and decrease in the potentially degradable fraction degradation rate. Ammoniation increased barley N content up to 44% with no change in rate of ruminal N release. Whole-tract true DM digestion was higher for ammoniated barley but N digestion was not influenced. Sulphur dioxide appears to offer no advantages beyond grain preservation, whereas ammoniation offers potential by reducting rate of ruminal DM release, and providing a source of slow release nonprotein N, without affecting post-ruminal digestibility. Key words: High-moisture barley, ammonia, sulphur dioxide

Key Concepts

The defining feature of memoirs as a genre is the understanding of the events and the author’s own role in them. The world of the language personality of the author-narrator becomes the dominant component, which forms the meaning of the text. One of the possibilities of its linguistic study is to rely on key concepts, which are implemented by some lexical units, reflecting the worldview of the narrator and showing the conceptual and idiostylistic nature of the text. Studying military memoirs of Marshal Rokossovsky allowed to reveal a special role of the word preparation, which has a high frequency of use and is of a high importance as an evaluation tool. It may be considered one of the key words of the text because it refl ects one of the major areas of focus of Rokossovsky during the war. Thus, the meaning of the text in the genre of memoirs and personality of its creator can be interpreted by considering the important components in the activities of the author-narrator. One concept predominates the meaning of their work and becomes one of the key-concepts. From the perspective of this key concept the author evaluates events and their participants as positive or negative.

Seventeen small, staminate flowers, 3.0–4.5 mm long × 1.0–1.5 mm wide, representing two developmental stages of the same type of flower have been recovered from the Middle Eocene Princeton chert locality of British Columbia. Some specimens are immature buds with overlapping perianth parts enclosing the stamens; others represent mature flowers with an open perianth. Flowers are pedicellate with a small flat receptacle bearing a perianth of at least three sepals and up to four petals. Five specimens show a three- to four-lobed rudimentary pistil surrounded by an intrastaminal nectary disk. The 10 stamens are included or barely exserted with nonconnate filaments, 1.2–2.0 mm long, attached by a slender connective to large dithecal anthers up to about 0.9 mm long that open by longitudinal slits. The anther wall is represented by a palisadelike endothecium composed of cells that are thick-walled and radially elongated relative to the long axis of the anther. Abundant in situ pollen is semitectate–columellate, tricolporate, subprolate to prolate, and prominently striated with equatorially bridged colpi. This fossil combines flower and pollen characteristics similar to those of the Sapindaceae, resembling most closely the tribe Dodonaeeae.

Community Energy Planning (CEP) is a process that allows municipalities to develop and implement local climate action, meet carbon reduction goals, and ensure a steady supply of clean energy. This MRP compares CEP in four municipalities in Ontario and British Columbia, to examine the reasons that led municipalities to undertake CEP and the roles that the municipalities undertook in the process. By using a policy comparison and interviews with Subject Matter Experts, the role that the municipality played to develop and implement CEP, and the role of the CEP within the community were evaluated. The municipalities studied were seen to have undertaken the expected roles to varying degrees and with various methods. Key Words: An article on energy and emissions planning in Canadian municipalities, used the key words: community energy planning, climate action, energy policy, local environmental planning
