Features of the impact of high-amplitude short pulses of hydrodynamic pressure on perforation channels
Authors:   Oil and Gas Research Institute RAS (OGRI RAS), Moscow, Russia, Svalov A. M.
Published: January 2023

The features of the impact of high-amplitude short pressure pulses on perforation channels in the bottomhole zone of the well are analyzed. It is shown that in the channels formed in the rock with the use of cumulative perforation and having a conical shape, there is an increase in pressure pulses when a certain condition is fulfilled, which limits the duration of this pulse. It has been established that in the negative phase of the pressure pulse, destruction of the cured rock layers adjacent to the walls of the perforation channel can occur, which improves the filtration-capacitive properties of the bottomhole zone of the well. It is shown that when using explosive charges of low mass, pressure pulses are formed with parameters similar to those of pulses generated by electric discharges in the wellbore. To apply the technology of explosive action with low-mass charges on the bottomhole zone, the standard equipment used for cumulative perforation of wells can be used. A method for screening pressure pulses is proposed, which increases the effectiveness of their impact on the bottomhole zone of the well and simultaneously reduces the excessive load on the casing pipes above the productive formation. Keywords: bottomhole zone of a well; perforation channels; electric discharge impact; low-mass charges; reflecting screen.

Portland cement is traditionally used in cementing of oil and gas wells. However, Portland cement has a number of shortcomings. The most important of these are the formation of microannuli between the cement plug and the rock or casing, as well as the formation of cracks and permeable channels in the cement matrix. Recent research shows that geopolymer can be a perspective alternate to portlandcement by overcoming beforementioned issues. The article comparatively analyzes the changes in the parameters of plugging materials containing geopolymer and Portland cement while contamination with water-based drilling mud. The results show that geopolymerbased solutions are more resistant to contamination with water-based drilling mud than Portland cement-based solutions. Thus, mixing Portland cement slurry with water-based drilling mud increases its viscosity and fluid loss, and sharply reduces its compressive strength. However, when a geopolymer solution is mixed with a water-based drilling fluid, its viscosity is almost unchanged, its fluid loss is reduced, and reduction in its compressive strength is less than in Portlandcement based material. Keywords: portland cement; geopolymer; fly ash; cementing; water based mud; mud contamination.

The operation modes of an extensional subsea pipeline of multiphase fluid at the initial stage of the offshore gas condensate field development under the conditions of liquid accumulation are studied. By means of the dynamic simulation of the slug flow mode, the frequency and volume of liquid plugs removed from the pipeline are analyzed as a function of the gas flow rate. It is demonstrated that with a decrease of the gas flow rate, the steadystate hydraulic calculations predict significantly lower values of the liquid volume flow rate at the pipeline outlet compared to the results of the dynamic simulation. The dynamics of the liquid removal from the pipeline with an increase of the gas flow rate is studied. It is shown that the surge liquid volume increases sharply at a rapid growth of the gas flow rate, which leads to restrictions on the increase in the well flow rate. Keywords: subsea pipeline; natural gas; multiphase fluid; liquid accumulation; slug flow.

Results of additional laboratory studies are presented for carbon dioxide utilization method with green generation of hydrogen and hydrocarbons. The method consists in interaction of water with dissolved CO2 on the surface of iron-containing fillers. The process proceeds at temperatures starting from ambient conditions and does not require creation of high pressures or electric current in the system. The interaction is accompanied by intense evolution of gas phase with high content of hydrogen. Carbon is transformed into carbonates and small quantities of generated hydrocarbons. Influence of temperature and process parameters is studied for steel turnings used as a prototype of cheap fillers produced from metalworking wastes. The possibility to optimize the degree of CO2 utilization is shown by controlling the carbonized water saturation pressure. According to the results of considered and previous series of experiments, the achieved degree of CO2 utilization is up to 76-83%, with hydrogen content in the output gas of 63-82%.

The article deals with the problems of distinction, types, recognition by composition in Kazakh linguistics of verbal combinations of two or three words. The paper reviewed the issues of the linguistic nature, word formation and grammatical nature of compound verb expressions. There are many opinions on the problem of the compound verb and the principles of their classification. The semantic features of complex verbal expressions are revealed. In this paper, we approach the concept of a complex verb by the criterion of composition and semantic integrity. For lexicography of complex verbal expressions, examples from a 15-volume explanatory dictionary of the Kazakh language, a phraseological dictionary and a text corpus of the Kazakh language were considered.In complex verb and analytical forms, verbs and compound verbs, as well as verb stable phrases, have semantic integrity, i.e. several syllables are connected and denote only one action, designating them as complex compound verb phrases. As with the lexicography of complex verbs, the principles of lexicography of analytical verbs and verb stable expressions are determined. Below are examples that explain the meaning of complex verb phrases (complex verb and verb of analytical form) and reveal semantic features.
A Review on Strategic Analysis of Australian
Supermarkets
Authors: Banerjee Swapan
Published: January 2023

In Australia, Coles and Woolworths are the two primary participants in the grocery
sector. They split about 80% of the whole retail market for groceries. In Sydney, one of
Australia's major cities, Woolworths launched new food kiosks in 1924, while Coles opened
the country's first supermarket in 1960. Coles and Woolworths consistently share most of
the market in the Australian supermarket industry, which is known as a "duopoly." Between
Coles and Woolworths and its retailers, there has been an imbalance of market power for
the last few decades (suppliers). Numerous studies indicate that Woolworths and Coles
conduct business in 840 and 741 supermarkets, respectively, in Australia. However,
regardless of the three variables, these essential players can only locate a suitable company
in the competitive and non-competitive market. The factors are buying power, selling power,
and retail chain. This duopoly, dominated by the two big business groups, can potentially
serve each retail product, including ready-to-eat foods, fresh food, and other essential retail
products. This short article is concerned with the strategic analysis of the two big players in
the Australian market, irrespective of environment, socioeconomic, politics, various usable
tools, techniques, rules, and regulations. Swot analysis, the Five force model, value, rarity,
imitability, and organization (VRIO) have been reviewed and discussed for both the market
leaders. The past, present, and future potentialities also have drawn in the article with the
snaky diagram and analytical tables. In conclusion, profit margins are obtained due to
successful differentiation, which enables the company to demand even higher prices.
Additionally, it promotes customer loyalty, which contributes to the financial stability and
growth of the business.

SETTING: In 2020, the National TB Programme (NTP) of Vietnam conducted an implementation pilot of the Simple One-Step (SOS) stool processing method using Xpert® MTB/RIF Ultra (Ultra) among children and people living with HIV (PLHIV) with signs and symptoms of TB.DESIGN
and OBJECTIVES: Using data from this pilot and collecting information on healthcare workers´ (HCWs) perceptions, we assessed the feasibility, acceptability and potential impact of routine stool testing for TB.RESULTS: HCWs perceived collection of stools from children as
least stressful of all sample types, stool processing as acceptable and the SOS stool method as easy to perform. After a 3-month induction period, the proportion of initial non-determinate Ultra stool tests was less than 5%. Combined Ultra testing of a respiratory sample and stool resulted
in an increase in the proportion of bacteriologically confirmed TB among PLHIV and children by respectively 4.1% (95% CI 1.6–6.6) and 3.9% (95% CI 1.6–6.2). Among children, Mycobacterium tuberculosis was more often detected in stool (26.1%) than in respiratory samples (23.4%)
(P = 0.06), including one child with rifampicin resistance.CONCLUSION: Stool testing can be feasibly implemented both in adult PLHIV and in children in routine settings, providing a non-invasive alternative sample type for the diagnosis of TB for patients who cannot produce
sputum.

I was recently challenged by an inter-professional clinical academic colleague that I might not be a ‘proper’ post-doctorate (post-doc) clinical academic (midwife). This caused me inner turmoil, which compounded the uncertainty I already had around my holding this title anyway. However, after a night of considering that perhaps it is futile and I should just give up trying to develop this new post-doc role, I accepted the unspoken challenge to articulate my realisation and justify my continuing effort to develop this role, thus enhancing practice.
Student Survival Guide No 5 - Courage and Compassion
Authors: Kay Carmel , Rojas Sabrina
Published: January 2023

This article aims to explore some of the limitations that student midwives experience within the clinical setting. Courage and compassion form part of the six basic competencies, commonly known as the six Cs. Compassion is an innate trait, whereas courage is a value that can be fostered. It has been established that students need to protect themselves from compassion fatigue and burnout. Students can achieve this by practising regular self-compassion. Students can be courageous practitioners, but there are concerns that they lack the relevant support. Advocacy is both a legal and ethical requirement of midwifery. These skills require time to develop and are linked to the self-esteem and confidence of the practitioner.

Published: January 2023

This paper takes all listed companies from 2016 to 2021 as research samples to study the impact of supply chain finance and accounting conservatism on corporate financing efficiency, and explore whether they have a substitution effect on financing efficiency or complement each other. The results show that supply chain finance and accounting conservatism can significantly improve financing efficiency. Accounting conservatism can be divided into conditional robustness and conditional robustness, among which conditional robustness and non-conditional robustness have positive effects on financing efficiency. The influence of accounting conservatism and supply chain finance on financing efficiency can be replaced by each other, that is, the existence of one variable will weaken the promoting effect of the other variable on financing efficiency.

Published: January 2023

In order to investigate the effect of different levels of niacin supplementation on physiological and blood biochemical parameters during heat stress period (April to August; 120 days), eighteen crossbred early lactating cows (2nd to 4th lactation; 11.56±1.74 days in milk) were divided into three groups of six animals each. The basal ration was fed same to all cows (Green fodder, straw and concentrate was fed as per NRC, 2001), except the addition of niacin @ 600 and 800 mg/kg dry matter intake (DMI) in T1 and T2 groups, respectively. The temperature humidity index (THI) was calculated at 07:30 am and 02:30 pm daily. Fortnightly physiological parameters were recorded and blood was collected from the jugular vein at day 0 and subsequently at 15–day interval from all the experimental animals to study blood biochemical parameters. The results revealed that animals were in either moderate or severe stress at morning, whereas during afternoon the animals were in very severe stress during the entire trial. Supplementation of niacin @ 800 ppm niacin decreased significantly skin temperature, respiration rate, cortisol, super oxide dismutase (SOD) and catalase (P<0.05). Plasma NEFA was significantly low in both niacin supplemented groups (P<0.05). Plasma urea was found significantly (P<0.05) high in T2 (26.59) in comparison to control (24.90) and T1 (25.37). It is concluded that 800 ppm niacin supplementation to lactating crossbred cows resulted in better stress alleviation as indicated by the improved biomarker values viz., SOD, catalase, cortisol and skin temperature.

Climate change is the leading ecologic, economic and geopolitical issue of the 21st century and has even the potential to rewrite the global equation for prosperity, development and peace. Adoption of agroforestry land use offers viable option for reducing some of the vagaries arising due to climate change especially the elevated level of CO2 and global warming. The realistic estimates of area and C-sequestration potential of agroforestry are essential for assessing its contribution of agroforestry in climate change mitigation. This has more relevance in current scenario when Maharashtra is facing drought condition especially in Marathawada region. The modern technologies like satellite remote sensing can provide spatially explicit information on land covers and natural resources like water. In the present study, estimation of area under tree cover and agroforestry has been done in Latur, Wardha, Nashik, and Thane districts of Maharashtra. The combination of remote sensing technique and CO2FIX model were applied to estimate agroforestry area and carbon sequestration in selected districts. Dynamic CO2FIX model v3.1 was used to assess the baseline carbon, i.e. year of survey (2013) and to estimate the carbon sequestration potential(CSP) of agroforestry systems for a simulation period of 30 years. Estimated area under agroforestry was in the range of 2.84% in Thane to 5.17% in Latur district and C-sequestration potential ranged from 0.06 to 0.41 Mg C/ha/yr. Study concluded that agroforestry has potential for carbon sequestration vis-Ã -vis climate change mitigation and a viable solution for coping the climate vagaries like drought.

A study on Dendrocalamus strictus + Sesamum indicum based agroforestry was conducted at ICAR-Central Agroforestry Research Institute, Jhansi (Uttar Pradesh), India during 2007 to 2012 to find out the suitability of bamboo based agroforestry system (AFS) in the semi-arid region. Bamboo recorded survival of 62 to 77% (1st year), 86 to 96 (2nd year) and 100% thereafter. D. strictus culm (No.) varied in the range of 178-388 (1st year); 936 to 1439 (2nd year); 1507 to 2134 (3rd year); 2182 to 2901 (4th year) and 2422 to 3215 (5th year, i.e. at harvest stage). Bamboo did not influence the sesame yields during initial two years, however, yield level got reduced during subsequent years. During 5th year intercropped sesame yield got reduced 15.69 (10m Ã— 10m bamboo) and 10.09% (10m Ã— 12m bamboo) as compared to pure crop. Bamboo clump affected the sesame yield substantially and 16.3, 14.3, 7.5 and 0.3% sesame yield reduction was observed at a distance of 1.0, 2.0, 3.0 and 4.0m, respectively, during 5th year. Organic C increased from 3.92 to 6.24 g/kg soil over a period of five years in bamboo based AFS. At harvest stage of bamboo (5th year), highest B:C ratio of 2.83 was observed in 10mÃ—10m bamboo + sesame followed by 2.59 (10mÃ—12m bamboo + sesame) and 1.43 (pure sesame). Therefore, bamboo based AFS has economic and environmental advantages over the sole crop and due to this, the system could be one of best alternative livelihood options for farmers of semi-arid tropics.

Tuberose (Polianthes tuberosa) occupies a very selective and special position for loose flower, cut flower and essential oils trade. Generally, in cut flower trade, Double petalled genotypes are more popular than single petalled. A particular genotype may or may not perform satisfactorily in a given location. Hence, seven double petalled tuberose genotypes, viz. Pearl Double, Arka Suvasini, Hyderabad Double, Arka Vaibhav, STR 505, Calcutta Double and Swarn Rekha were evaluated during 2012-2013 for various vegetative growth, floral and bulb traits under open field condition at ICAR- Directorate of Floricultural Research, New Delhi. Significant variations for all studied parameters were recorded in evaluated genotypes. Cultivar Swarn Rekha produced significantly higher plant height (47.03 cm) followed by cv. Arka Vaibhav (44.43 cm). The lowest plant height was recorded in cv. STR 505 (38.26cm). Maximum width of leaves (2.29 cm), fresh weight of leaves (130.28 g) and dry weight of leaves (19.18 g) per clump and number of spikes per plot (143.00) were recorded in cv. Arka Vaibhav. Cultivar Hyderabad Double took maximum number of days to first flowering (120.00) and cv. Arka Suvasini took least days to first flowering (100.00). Higher number of leaves per clump (33.55), flowering duration (24.55 day), spike length (91.91 cm), rachis length(47.84 cm), spike diameter (12.41 mm), number of florets/spike (69.90), fresh weight of florets/spike (253.83 g), fresh weight (191.90 g) and dry weight (19.14 g) of cut spike, number of tepals/floret (24.19), diameter (5.46 cm) and length (6.40 cm) of open floret, diameter (12.24 mm) and length (5.31 cm) of mature floret and weight of 10 open(46.80 g) and mature (23.20 g) florets, number of bulbs (17.00) and bulblets (9.38) per clump, total weight of bulbs (302.53 g) and bulblets (29.96 g) per clump, average diameter of bulb (28.09 mm) and bulblet (11.23 mm), average weight of bulb (27.03 g) and bulblet (3.78 g) and average length of bulb (7.46 cm) were obtained in cv. Arka Suvasini. In all genotypes, no seed setting was reported. Cultivar Arka Vaibhav developed greenish floret at bud stage, while remaining six genotypes developed pinkish flower bud. Higher internodal length was measured in cv. STR 505 (6.40cm) and shorter in Arka Vaibhav (4.71 cm). The lowest values for majority of the vegetative growth, floral and bulb parameters were recorded in cv. Swarn Rekha. However, the lowest values for bulblet development parameters were obtained in cv. Arka Vaibhav. Conclusively, based on overall yield and quality parameters, cv. Arka Suvasini and Arka Vaibhav were found to be most promising and can be recommended for future commercialization.

Published: January 2023

The effect of vernalization on reproductive potential of garlic (Allium sativum L.) especially on flowering and its true seed production behaviour which includes bolting behaviour, scape colour, flower colour, bulbil colour, number of bulbils per umbel, scape length and number of seeds per umbel were studied under North Indian Plain conditions. The thirteen â€˜seed producingâ€™ garlic genotypes which produce true seed under USA (long day) conditions were used in the present study and were given vernalization treatment at 4oC for two months before sowing. In control treatment, garlic bulbs were kept at room temperature before sowing. The vernalization of garlic bulbs at 4oC (for two months) resulted in bolting, umbel formation and true seed production in nine genotypes, whereas non-vernalized did not result into bolting, i.e. no true seed production was observed. Out of nine true seed producing garlic genotypes, the maximum seed setting was observed in genotypes 5366, 5351 and 5477 having values of 20.0, 18.0 and 13.0 seeds per umbel. The seed received from these genotypes were further sown but they did not germinated. These genotypes can be used in breeding programme, if these are sown under long day conditions. The highly significant and positive correlation was observed between number of seeds per umbel and scape length (r= 0.99); significant and positive correlation for number of seeds per umbel and number of bulbils per umbel (r=0.58); significant and positive correlation for number of bulbils per umbel and scape length (r=0.61). It was and also observed that when vernalization treatment was given to the 13 different genotypes of the garlic; out of them, nine complete genotypes produce flowers and after bulbil removal process resulted in true seed production. True seed production in garlic has the practical significance as it generates genetic variation which can be exploited in garlic breeding.

The specialist generalist engineer
Authors: McGilveray Hugh , Pierce Simon
Published: January 2023

The organic and reactive professionalisation of the construction industry has resulted in a complex picture which has brought with it a series of problems and threats to the engineering sector. Technical aspects of building projects are becoming increasingly important design drivers, with stringent performance requirements, modern materials and complex systems taking the place of traditional construction methods. Yet the engineering sector appears to be becoming more and more disparate; with holism becoming harder to obtain due to commoditisation and inappropriate procurement. This paper proposes, in principal, a potential solution to this through the upskilling of engineering professionals to become ‘specialist generalist technical lead’ designers within a renewed and simplified core design team. Consulting structural engineers or facade engineers, being tuned to be as technically competent as they are practical, and as design sensitive as they are aware of technical feasibility and cost, are perfectly suited to fulfil an increased need for this specialist generalist figure who can complement the architect from a technical perspective and harness the best of specialist designers, while maintaining a holistic outlook on the technical and sustainability aspects of a project.

Data collection and aggregation by online services happens to an extent that is often beyond awareness and comprehension of its users. Transparency tools become crucial to inform people, though it is unclear how well they work. To investigate this matter, we conducted a user study focusing on Facebook, which has recently released the 'Off-Facebook Activity' transparency dashboard that informs about personal data collection from third parties. We exposed a group of n = 100 participants to the dashboard and surveyed their level of awareness and reactions to understand how transparency impacts users' privacy attitudes and intended behavior. Our participants were surprised about the massive amount of collected data, became significantly less comfortable with data collection, and more likely to take protective measures. Collaterally, we observed that current consent schemes are inadequate. Based on the survey findings, we make recommendations for more usable transparency and highlight the need to raise awareness about transparency tools and to provide easily actionable privacy controls.
