Authors: KUŞ Emrah , YILDIRIM Yıldıran
Published: May 2020

This study was conducted to determine the effects of seed drop height and tractor forward speed in different tillage systems on the mean emergence time, emergence rate index, and percentage emergence in single seed planters. The experiments were carried out in the conventional and reduced tillage systems, at seed drop heights of 120, 180, and 240 mm and tractor forward speeds of 1.1, 1.5, and 2.2 m s-1. Sunflower and maize seeds were used in the study. The results of the study showed that seed drop height significantly affected the mean emergence time, emergence rate index, and percent emergence in both experiments (P<0.05). Also, the tillage system significantly affected the mean emergence time and emergence rate index. The lowest mean emergence time and the highest emergence rate index were 10 d and 0.19 seedlings d-1 m-1 in the reduced tillage system for sunflower, respectively. The same parameters were 12 d and 0.37 seedlings d-1 m-1 in the reduced tillage system for maize, respectively. As a result, the seeds of sunflower and maize should be sowed in reduced tillage system, 180 mm seed drop height, and 1.1 - 1.5 m s-1 tractor forward speeds for rapid germination and high percentage emergence.

Over the last five years, we have seen the rise of a new generation of ‘soft AI’ digital assistants like Apple’s Siri, Microsoft’s Cortana, and Amazon’s Alexa, all designed with feminized personas. In this paper, we connect these AI assistants to the long history of the secretary, beginning with secretary as a desk and then as a profession, emblematized by the executive assistant.  How have the gendered practices of organization, anticipation and surveillance been reinvoked in AI agents? How do AI secretaries present new relationships to work, computation and the increasing entanglements of bodies and data?
‘Keeping Them Down’
Authors: Sánchez Barba Mayra G.
Published: May 2020

Chlorpyrifos, the most widely used insecticide in the US, has gained great notoriety as a contested chemical substance after the U.S. Environmental Protection Agency refused to ban it in 2017. Arguing that scientific studies support their observations and suspicions that agricultural pesticides subtly produce neurological and cognitive harm, concerned groups continue to demand US regulatory agencies to ban this chemical. Their narratives demonstrate how the maintenance of unequal racial and capitalist orders across generational time is tied to small chemical exposures permitted by state regulatory agencies during critical temporalities in the life course. This essay shows the importance of including local perspectives in research that seeks to understand how concerns for the mass neurological and cognitive disabling emerge from lived experiences entangled in histories of racism, exploitation, and neglect. Interweaving feminist science and technology studies, queer theory, and critical disability studies, this analysis contributes to the limited scholarship on cognitive disabling in contexts of environmental injustice through exposure to industrially produced chemicals.
Carpet Bombings
Authors: Grandia Liza
Published: May 2020

Outdoor images predominate in our cultural conceptions of “air pollution” even though indoor air quality (IAQ) is typically tenfold more contaminated.   New modeling of LA smog in Science suggests that source emissions from indoor and personal care products contribute more to that city’s infamous poor air quality than vehicular combustion.  In similar paradox, even as outdoor smoke from California wildfires in 2017 pushed PM2.5 levels past red into unprecedented magenta alerts, children were sickened inside school classrooms after new carpets were laid.  This auto-ethnographic paper chronicles our ongoing struggle to remove those carpets from “Beacon” Elementary, a bilingual Mexican-American school in California's Central Valley that has suffered decades of racialized neglect of its facilities. Forging through the uncertain epidemiology of environmental illness, “Beacon” mothers began documenting their children’s ailments after the new carpet installation, but the school district dismissed the mothers' citizen science.  The Superintendent continued to vouch for the carpet’s safety based on the industry’s voluntary “Green Label.”  A historical section of this article therefore recounts how and why the carpet industry invented this label in the aftermath of a scandal in which new carpets sickened a fifth of the EPA workforce at their headquarters in Washington, DC between 1987 and 1988.  Thirty years later, once again, three California environmental regulatory agencies are scrutinizing the carpet industry for hazardous ingredients.
On Language, Scientific Metaphor, and Endocrine Disruption: An Interview with Feminist Scientist Ana Soto
Authors: Soto Ana , Brilmyer Gracen
Published: May 2020

In the late 1980s, Professor of Immunology Ana Soto accidentally discovered the presence of synthetic estrogens in her lab equipment. Her lab had designed an experiment to test the effect of estrogen on the proliferation of human breast cancer cells (MCF7). Based on previous findings, Soto and her research partner Carlos Sonnenschein believed that, contrary to popular wisdom, the introduction of estrogen would not directly induce the proliferation of the cells, but would instead interfere with a naturally occurring inhibitor in the blood. But the control setup containing positive and negative controls (used in the past without problem) was now producing odd readings: although no estrogenic compound had been introduced, the cancer cells were still proliferating. Soto and Sonnenschein methodically removed each item in the control setup that might be producing the estrogen-like result. When they discovered that the estrogenic activity leached from the plastic centrifuge tubes used to store components of the cell culture medium, they called the manufacturer to find out what could have changed. The manufacturer let them know that the constituent materials of the tubes had recently been modified in order to reduce the possibility of breakage during centrifugation but declined to reveal what specific changes had been made. So Soto’s lab turned to studying the tubes themselves. After a year of further research, they concluded that the estrogenic activity was due to the additive that had been introduced by the manufacturer—nonylphenol, an antioxidant used in numerous other applications, some of which are meant for human use (e.g., spermicide) and the synthesis of detergents. Soto and Sonnenschein’s  assay is called E-SCREEN and  has been enormously influential; in fact, most of the environmental estrogens discovered in the 1990s rely on it.

Conducted by Gracen Brilmyer at UCLA during the Chemical Entanglements Symposium, this 2017 interview with Soto highlights her experiences of sexism in the sciences and how those experiences have shaped her thinking on language, science, and scholarship

The results of a comparative study of the main characteristics of the biochemical composition of fruits of the same age of generative plants of 5 introduced varieties of V. corymbosum of different ripening dates – early ripening Weymouth, mid-ripening Bluecrop and Concord, late ripening Elizabeth and Atlantic obtained by traditional (stem-cuttings) and microclonal vegetative methods are presented. A significant effect of the propagation method on the biochemical composition of the fruits, the degree of which was determined by the chemical nature of its components and the plant genotype, was established. In the fruits of cloned plants, depending on the genotype, ambiguous changes in the range of 5–40 %, relative to traditional plants, in the content of solids, free organic, ascorbic and hydroxycinnamic acids, soluble sugars and pectin substances, as well as the index of sugar acid index, were revealed. For most varieties, a common trend in the nature of differences between cloned and traditional plants in the accumulation of bioflavonoids was shown, consisting in the increase in the first case of their total number by 5–27 %, including 6–34 % of anthocyanin pigments. The greatest positive effect of the microclonal propagation method on the content of P-vitamins in fruits of late ripening varieties, especially Atlantik, was found, with a 3–6 times lesser degree of similar influence in Weymouth and Concord varieties, against the background of the prevailing negative effect in mid-ripening Bluecrop. With the relative stability of the ratio of the components of the P-vitamin complex of blueberry fruits to the tested propagation methods, significant shifts were revealed in the composition of their anthocyanin complex in cloned plants of early ripening and especially mid-ripening varieties towards a decrease in the proportion of anthocyanins proper and an increase in that of leukoanthocyanins, compared to traditional plants, reaching 1.5–1.6-fold value in Concord variety with the opposite direction of less pronounced shifts in late-ripening varieties.

In cloned plants (with the exception of the Bluecrop variety), the integral level of the nutritional and vitamin value of the fruits was found to be 2.6–4.4 times higher than their traditional counterparts by a total of 14 indicators of the biochemical composition when the varieties were arranged in accordance with a decrease in the degree of data differences in the series: Atlantik > Elizabeth > Weymouth > Concord > Bluecrop, in which late ripe varieties of blueberries were characterized by the greatest advantages.
Creation of strain – producer of bacterial purine nucleoside phosphorylase fused with human annexin A5
Authors: Bulatovski A. B. , Zinchenko A. I.
Published: May 2020

It is known that bacterial purine nucleoside phosphorylase (PNPase), unlike mammalian PNPase, is capable of phosphorolytic cleavage of adenosine and its derivatives to form free nitrogen bases. This makes it possible to use bacterial PNPase (provided the problem of delivering this enzyme or its gene to target cells is solved) as a prodrug therapy for cancer. In addition, PNPase in a tumor bed can destroy extracellular adenosine, which is known to protect cancer cells from antitumor immunity.

As a result of the study, a new strain of Escherichia coli was constructed, producing a chimeric protein whose molecule consists of a homologous PNPase fused to human annexin A5, a protein showing affinity for cancer cells.

The production capacity of the producer strain of the chimeric protein “Annexin-PNPase” with respect to PNPase calculated from the results of the inosine phosphorolysis reaction, was 10,200 units/ml of culture liquid. The obtained strain is intended for creation of a technology for obtaining new antitumor preparations.
Structural characteristics of the cenopopulations of Atraphaxis frutescens (L.) C. Koch (Polygonaceae) in the territory of botanically valuable natural complexes of the Samara region
Authors: Il’ina V. N.
Published: May 2020

The reduction in the area occupied by the petrophytic steppes of the European part of Russia, including in the Samara region, due to alienation under agricultural land and high anthropogenic pressure, led to a decrease in the total number of plant species in the steppe and mountain-steppe flora. The current state of the species of these phytocenotic groups in the regions also depends on the ecological and biological characteristics of the representatives.

The object of study is Atraphaxis frutescens (L.) C. Koch (Polygonaceae). On the territory of the Samara Pre-Volga and Trans-Volga regions, the structure and current state of 21 coenopopulations were studied. In the course of the work, traditional population-ontogenetic techniques and recommendations were used. The heterogeneity of the ontogenetic spectra was revealed, the regional basic ontogenetic spectrum of Atraphaxis frutescens cenopopulations, the main demographic parameters (including the age-effectiveness criterion L. A. Zhivotovsky was used to determine the type of cenopopulations) were determined. Based on data on the population structure, the protection efficiency of Atraphaxis frutescens as part of nature monuments of regional significance is analyzed in comparison with other valuable natural complexes that do not have conservation status. It has been established that with low and medium load on the vegetation cover, natural monuments are able to ensure the preservation of the species in the region. Significant differences in the ontogenetic spectra of coenopopulations in and beyond protected areas were not noted. In the coenopopulations of A. frutescens in protected areas, there is a slight increase in the number of old generative plants (31.4 %) and a decrease in the proportion of subsenile individuals (7.1 %). The average area of the geographical population on the territory of protected natural complexes is 850 m2, the average number is 2011.7 generative individuals; outside the protected areas, the population area is 275 m2 and the number of individuals is 642.4.

Thus, natural monuments contribute to better conservation of the area of the geographical population, ensure the stability of the number of individuals and spatial distribution, including the formation of large aggregations of individuals and a more even distribution of recorded aggregations.
Molecular mechanisms of high-affinity interaction of the protein tBid with the mitochondrial complex МТСН2-МОАР-1
Authors: Dudko H. V. , Urban V. A. , Veresov V. G.
Published: May 2020

Mitochondrial carrier homolog 2 (MTCH2) is a protein that plays an important role in the execution of apoptosis being a receptor for tBid in the outer membrane of mitochondria. Previously, it has been shown that the binding of the modulator of apoptosis-1 (MOAP-1) protein to MTCH2 is required for the efficient MTCH2-mediated recruitment of tBid to mitochondria and, in contrast, tBid is required for the MOAP-1 recruitment to mitochondria, but the structure understanding of these phenomena is absent. In this study, we have provided structural insights into the mechanisms of regulation of the MTCH2 receptor function for tBid by MOAP-1.

We evaluated the rate of polymorphism of doubled haploid lines of hexaploid triticale obtained by the method of anther culture based on hybrids of spring and winter types. Using 7 SSR markers for the loci on the chromosomes A- (Xgwm186, Xgwm291, Xgwm595) and B- (Xgwm371, Xgwm540, Xgwm554, Xgwm234), polymorphism of 38 doubled haploid lines of hexaploid triticale was studied. Interlinear polymorphism along six microsatellite loci except the Xgwm554 locus, which is not polymorphic in the studied doubled haploid lines, was revealed. The highest polymorphism was observed for the Xgwm186, Xgwm291 and Xgwm595 loci. The cluster analysis showed that all studied lines were divided into three main groups. The origin of the lines did not affect the distribution in groups. This confirms the influence of in vitro culture somaclonal variation. Eight lines of doubled haploids, which are heterozygous for one of the studied microsatellite loci, were identified. We showed the possibility of using SSR markers to assess interlinear polymorphism and the homozygosity rate in the triticale doubled haploid lines obtained by the method of induced androgenesis in vitro.

The genealogical breed structure is represented by 5 main factory lines: Zubr, Zenit, Zaslon, Zont, Zefir. The genealogical structure of the Belarusian meat breed is formed using the generally accepted selection methods, including the assessment by pedigree, strict selection, targeted selection, the assessment of replacement young by productivity on elevers, the assessment of boars and queens by the offspring quality using the control feeding method. The targeted breeding work with herds of Belarusian meat breed pigs during a long period of time according to the long-term target program allows us to obtain large boars and queens that are characterized by the meat-type body. When assessing boar-producers of the Belarusian meat breed aged 36 months and older in all farms the values of the body live weight and length were on the average 305.3 kg and 179 cm respectively. As a result of studying the reproductive qualities of animals, it is established that, on the average, in the queens selected into the leading group in all farms, the indicators of prolificacy, the weight of one young pig at birth, the number of young pigs aged 21 days and milking ability were 11.74 animals and 1.11 kg, 10.06 animals and 54.34 respectively. The highest growth rate from birth to a live weight of 100 kg was seen in the Zefir line animals – 550 g. The indicator of the growth in reaching a live weight of 100 kg was 181 days. The superiority over the mean indicators of animals of all lines according to these traits was 10.7 days, or 5.6 % and 31 g, or 6.0 % respectively. The Zalon and Zenit line offsprings were inferior to the boars of the rest lines in terms of the growth in reaching a live weight of 100 kg by 2.8–19 days. Their indicators of the daily average growth from birth to a live weight of 100 kg also appeared to be, on the average, lower by 6–49 g. The differences in the Zaslon line boars were confident (р ≤ 0.05).

Published: May 2020

In conditions of global climate change, it is important to develop reliable models allowing to reliably predict plant development based on combination of the Earth remote sensing data and statistical modeling. Modeling by means of Markov chains is an efficient and at the same time simple way to predict random events, which include prediction of performance of phytomass of agricultural crops. The Earth remote sensing data obtained from the Sentinel-2 satellite with spatial resolution of 10 m were used to calculate the value of vegetation index NDVI and obtain different time rasters (2017-2019) with different degrees of vegetation cover development. To construct the matrix of probability of transition from one state to another for different levels of vegetation cover development, functionality of geoinformation systems (GIS) were used allowing to classify raster images, transform them into vector layers, and establish intersection areas. The probability matrix was later used to predict vegetation cover development using the Markov model as a predictor. The developed prediction model was tested for feasibility of the χ2 test. The results obtained showed that both the modeled values and the actual area of vegetation distribution with different degrees of development, determined from the available raster image of 2019, correlated well with each other. The research results can be useful both in developing forecasting methods and in directly predicting the crop yield of primarily dense-cover agricultural crops, as well as for estimating performance of pastures and creating efficient pasture rotations.

Authors: Mulyaqin Tian
Published: May 2020

Rice production in Indonesia is facing serious problem, in which the production is fluctuated causing the unstability in the food supply. One factor influencing the rice productions is climate extreme. Here, we analysed rice production in Banten Province for 2002-2015. The objective of this reasearh was to analyse the effect of climate variability on the fluctuation of rice production in Banten. We relied on data from BPS Banten, which provided timeseries of rice production for 2002-2015. We used four statistical approaches namely linear, quadratic, exponential, and moving average models to detect trend in rice production. Our results showed that Rice Production fluctuated every year indicating an increased trend for the observartion period. Based on the trend analysis, the growth rate for rice production was 1,66% per year. Climate extreme has affected on rice production, with El Niño resulted in the decreasing on rice production, whereas La Nina caused an increased of rice production. Further, to adapt climate extreme events, the government needs to encourage farmers to join the Rice Farming Insurance (AUTP) program to protect rice farming from economic losses due to the climate extreme impacts.

Published: May 2020

Background: Female Genital Mutilation (FGM) remains a common cultural practice in Benin City, Edo State and by extension, Nigeria. The knowledge and attitude towards FGM may play significant roles in influencing this harmful socio-cultural practice.

Objective: To identify factors associated with knowledge and attitude towards female genital mutilation (FGM) among Antenatal Clinic (ANC) attendees in selected health facilities in Benin City, Edo State.

Methods: A facility-based, descriptive, cross-sectional study was conducted involving 400 pregnant women recruited by systematic sampling technique from selected health facilities in Benin City, Edo State. A pre-tested, interviewer-administered questionnaire was utilized for data collection from consenting pregnant women attending antenatal care clinics in selected public tertiary and secondary health facilities in the study area. Information related to socio-demographic characteristics, knowledge, and attitude towards FGM were collected.

Results: The mean age of the respondents was 30.3±4.8 years. All the respondents were aware of the term Female Genital Mutilation. Two hundred and forty-eight (62%) and 302 (75.5%) had good knowledge and negative attitude towards FGM respectively. Age group (p = 0.005), religion (p = 0.007) and educational status (p <0.001) were identified as significant factors influencing knowledge of FGM while in relation to attitude towards FGM, knowledge of FGM (p<0.001) had significant influence.

Conclusion: This study identified a gap between knowledge and attitude towards FGM among the respondents. Good knowledge of FGM significantly influenced attitude towards FGM. There is a need to scale up health sensitization during ANC sessions to bridge the gap identified.

Authors: Smith OS , Adegoke SA , Akinlosotu MA , Ajose OA
Published: May 2020

Background: Sickle cell anaemia has been associated with oxidative stress. Total Antioxidant Capacity (TAC), Total Oxidant Status (TOS) and Oxidative Stress Index (OSI) are cumulative markers of oxidative stress.

Objective: To evaluate the serum levels of oxidative stress markers in children with sickle cell anaemia (SCA) and determine the relationship between these markers and disease severity.

Method: One hundred and fifty-six children, comprising 78 with SCA, aged 1 - 15 years and 78 age- and sex-matched Haemoglobin AA controls were studied. Serum TOS, OSI, and TAC were determined using ELISA kits. The severity of the SCA was determined using clinical and laboratory parameters.

Result: Children with SCA had lower mean serum TAC (0.83±0.31UAE) than controls (1.19±0.24UAE) with p<0.001. However, the mean serum TOS and OSI of children with SCA was higher than among the controls (13.33±4.64U/ml vs. 9.70±2.72U/ml and 20.95±16.75 vs. 8.68±3.76 respectively) with p<0.001. SCA subjects with mild disease had higher mean serum TAC (0.91 ± 0.27UAE) than those with moderate disease (0.54±0.27UAE) (p<0.001). On the other hand, the mean TOS and OSI were lower in children with mild disease compared to those with moderate disease (12.64±4.32U/ml vs. 15.63±5.07U/ml, p = 0.016 and 16.26±10.25 vs. 36.61±23.89 p<0.001 respectively). Sickle cell disease severity score had negative correlation with TAC (r = -0.60, p < 0.001) but positive correlation with TOS (r = 0.3, p = 0.008) and OSI (r = 0.6, p < 0.001).

Conclusion: Children with SCA had lower TAC but higher TOS and OSI than matched controls. Oxidative stress markers had a significant relationship with SCD severity.

Published: May 2020

Background: Pregnancy and childbirth are normal physiological processes. The best outcomes of most pregnancies are possible if adequate care is provided during pregnancy. Parity is one of the major determinants of pregnancy outcome.

Objectives: To compare the pregnancy, labour and foetal outcomes of booked nulliparous and primiparous women.

Methods: This is a retrospective, cross-sectional study conducted in the Department of Obstetrics and Gynaecology, Olabisi Onabanjo Teaching Hospital, Sagamu, Ogun State Nigeria from January 2014 to December 2016.

Results: There was a significant difference between the mean age at booking of the nulliparous (Para 0) (26.7±4.4 years) and primiparous (Para 1) women (29.1±4.1 years) (p <0.001). The estimated gestational age (in weeks) at delivery was 38.1±4.8 in the Para 0 group and 38.2±3.9 in the Para 1 group. The mean duration of the first stage of labour was 11.3 ±5.7 hours in the Para 0 but 9.5 ± 5.3 hours in the Para 1 group and the difference was statistically significant (P<0.001). The maternal outcome was favourable in both groups of women even though two unavoidable deaths were recorded in the Para 1 group. The foetal outcomes in the two groups were comparable and both the Crude Odd Ratio and the Adjusted Odd Ratio differences in the two groups did not reach a significant level.

Conclusion: Delivery outcomes in both groups were favourable and comparable. This can be attributed to the standard antenatal care received by both groups and well-supervised deliveries.

Background: An important aspect of the surgical management of breast cancer is loco-regional control which can be accomplished by either breast conservation surgery or mastectomy.

Objective: To examine the outcome of the operation of mastectomy with respect to the complications of the procedure.

Methods: This is a retrospective study of all the patients who had a mastectomy for breast cancer in a Nigerian tertiary care centre from 1st January 2012 to March 2019. The hospital records of the patients were retrieved. Demographic and relevant clinical characteristics of the patients were extracted.

Results: A total of 77 cases were eligible, 76 women and one man. The age range was 28-76 years. Right mastectomy was performed in 54.5% cases. Preoperative comorbiditiesincludedobesity(34%), hypertension (31.2%), anaemia (6.5%) and Diabetes mellitus (7.8%). Modified radical mastectomy was done in 51.9% cases, simple mastectomy in 36.4%, “Toilet Mastectomy”in 9.1%, and mastectomy after breast conservation treatment in 2%. Twenty-eight percent of the cases required a blood transfusion, 31.2% received neoadjuvant chemotherapy while 58.2% had adjuvant therapy. The complications observed included: haemorrhage (7.8%), seroma (9.1%), flap necrosis (9.1%) andtumourrecurrence (7.8%). As at the time of the report, 41.6 % were alive, 19.4% were dead and 39.0% were lost to follow-up.

Conclusion:The complications of mastectomy were mostly haemorrhage, seroma,and flap necrosis, similar to previous reports from other parts of the world.

Vertical land motion (VLM) is an important indicator in obtaining information about relative sea-level rise (SLR) in the coastal environment, but this remains an area of study poorly investigated in Indonesia. The purpose of this study is to investigate the significance of the influence of VLM and SLR on inundation. We address this issue for Semarang, Central Java, by estimating VLM using the small baseline subset time series interferometry SAR method for 24 Sentinel-1 satellite data for the period March 2017 to May 2019. The interferometric synthetic aperture radar (InSAR) method was used to reveal the phase difference between two SAR images with two repetitions of satellite track at different times. The results of this study indicate that the average land subsidence that occurred in Semarang between March 2017 and May 2019 was from (-121) mm/year to + 24 mm/year. Through a combination of VLM and SLR scenario data obtained from the Intergovernmental Panel on Climate Change (IPCC), it was found that the Semarang coastal zone will continue to shrink due to inundation (forecast at 7% in 2065 and 10% in 2100).

Authors: Kien Nguyen Chi , Kashaev R. S.
Published: May 2020

The article describes a bench for studying a system of a flow analyzer based on nuclear (proton) magnetic resonance (PMRA), used for the operational control of proton-containing multicomponent liquids (oils, fuels, oil and chemical products) and mixtures for viscosity and composition (concentration of asphaltenes and resins ) during oil production, oil preparation and use at energy facilities in the analysis of liquid fuel. This article also looks at the equipment that is used to control oil parameters with PMR-Relaxometry. Particular attention should be paid to the analysis of physical and chemical properties of oil components with the use of PMR. The use of sampling equipment for the purpose of controlling the rapid flow of oil parameters by the PMR method will eliminate phase separation in the sampling device and eliminate clogging with waste sediments, ensure efficient homogenization of the fluid flow in the sampler, as well as automate the measurement process.
Estimation of energy efficiency of kraft pulp production with the exergy increment method
Authors: Lukanin Р. V.
Published: May 2020

This article contains results of exergic analysis of kraft pulping flow chart. The results of exergic balances of main kraft pulping processes such as alkali recovery at recovery boilers, black liquor evaporation, chips cooking, lime decarbonation are considered in details in the article. The analysis of the process flow chart makes it possible to determine the bottlenecks in the use of heat energy and to substantiate principal lines for increasing energy efficiency of the processes under study. A main share of the exergy expended in the existing pulping process is due to alkali recovery in the recovery boiler and comprises 70% of the total exergy available in the system. A procedure of hydrothermal production of chemicals in the process of kraft pulping is studied. A schematic diagram and analysis of heat technique of the kraft pulping process which in fact consists of organic component removal from black liquor through its autoclave carbonation with flue gases releasing from lime kiln at the temperature 80-90 oC are given in the article. The removal of organic components under these conditions can reach 70 %. In the studied version the exergic efficiency ηe = 80 % is considerably higher than that of the flow chart existing for chemicals recovery which is equal to ηe = 48 %. This is the evidence of high energy efficiency of the method developed.

One of the key aspects in the development of power engineering all over the world is the use of distributed small-scale generation. This is both based on fuel carbon resources with a synchronized connection between sources when they are connected to the electric power grids and renewable energy sources operated in the electrical grid via frequency converters (electronic generation). The latter brings an inevitable broad use of inverters in available AC power systems. The objectives of this paper are numerous. First is the desire to study the effect of electronic generation on modes and stability of current electrical grids and electrical power systems. Another objective is to establish requirements for electronic generation control that lets us minimize actions on relay protection coordination and automation upon the integration of electronic generation in power grids. A final objective is to increase the reliability of general electrical modes. This article shows the outcomes of the study on the statical aperiodic stability of the electrical power system upon the integration of electronic generation, requirements for its statical characteristics, and the control when operated within the electrical power system.

An Examination of the #NGSSchat Storify Database
Authors: Borchers Conrad , Rosenberg Joshua , Fischer Christian
Published: May 2020

Teachers frequently use Twitter to engage in professional learning activities. A prominent example of teachers’ use of Twitter for such purposes is evident within the #NGSSchat community, which encouraged synchronous (at the same time) conversations between teachers and other educational stakeholders regarding the Next Generation Science Standards (NGSS) curriculum reform in the United States. Notably, #NGSSchat moderators archived the chats via the Storify platform, which has subsequently been used by researchers to understand science teachers’ professional learning activities on Twitter. However, what has not been established is the representativeness of this archive of #NGSSchat tweets. In other words, whether those who archived #NGSSchat content selected only a (potentially biased) selection of tweets is as yet unknown. Thus, in this study, we examined the Storify #NGSSchat database and compared it with raw data requests using the Twitter API. We found that the synchronous chats most data was adequately achieved. Contrarily (but as anticipated given what distinguishes the #NGSSchat community-synchronous conversations), the Storify #NGSSchat database did not capture most data outside these synchronous chat sessions. Importantly, we did not find an indication of systematic content- or user-driven tweet exclusion within the synchronous NGSS chat sessions on Storify, suggesting that the #NGSSchat archive via Storify (and potentially others like it) may be used by researchers for most research-related purposes.
