Physiological Response of an Oil-Producing Microalgal Strain to Salinity and Light Stress

By separating and extracting algae from the collected water samples, an oil-producing diatom strain was obtained. Microscopic observation of the strain revealed that its morphological characteristics were highly similar to those of the genus Cyclotella. The cloning of 18S rDNA and phylogenetic analysis showed that the algae were clustered with Cyclotella menegheniana with a high support rate, indicating that the alga was C. menegheniana. The fatty acid content of the alga was determined and found to be mainly C14, C16, and C18 fatty acids, which were in accordance with the relevant standards for edible oil. In this study, different gradient levels of salinity and light were set to investigate the culture and bioactive substance production of C. menegheniana. The results showed that the best growth condition was achieved when the salinity was 15 g·L−1, and its biomass and oil content were the highest at 0.27 g·L−1 and 21%, respectively. The final biomass was the highest when the light intensity was 2000 Lux and the oil content was 18.7%. The results of the study provided a basis for the large-scale production of edible oils and biodiesel.

Genetic Diversity of Natural Morchella spp. from the Southern Gansu Province Based on rDNA-ITS, China

Background: China is a mainland country rich in natural Morchella spp. resources. At present, about half of the natural Morchella spp. in the world has been recorded in China. The current study was aimed at the classification and cultivation of Morchella spp. This study provided a more accurate molecular trait for the systematic classification of Morchella spp. in southern Gansu Province, China.Methods: From April to May 2019. Based on the molecular biological analysis of 16 natural Morchella spp. strains collected from the southern Gansu province, China. the ITS fragments between transcripts of the rDNA gene were amplified by PCR and sequenced.Result: The results of BLAST comparison according to GenBank showed that the 16 tested strains of Morchella spp. were classified into 5 species, which were M.angusticeps, M.esculenta, M.elata, M.crapssipes and M.conica. According to the molecular evolutionary trees constructed by the Maximum-Parsimony method (MP) and the Neighbour-Joining method (NJ), the topological structures of the two molecular evolutionary trees were similar and the Bootstrap verification had a high support rate, indicating that the phylogenetic relationship had high credibility.

Perception of masculinity in rural family structure

Research Problem/aim: The objective of this study is to determine the perception of masculinity in rural family structure Methods: This research is a descriptive and analytical study. The universe of the research, which was conducted between the dates of 14.11.2016 - 31.05.2017, is the people of Akşehir district of Konya Province. Individuals aged 18 and over (n=500), who participated voluntarily, were included in the research, particular attention was paid to acquire the written and verbal consents of the participants prior to the application. Findings: Participants are between the ages of 18 to 65 and the median age is 27.57±10.22. Almost all of the women, at 92.9%, disagree with the "the man should decide how to use the household income" statement, while 38,7% of men support this statement, it can be seen that the provided responses change according to genders (p=.000). Both genders accept the "the man is the head of the household" statement, while 39.5% of women agree with this statement, at high rates, at 74.9%, men support this statement. While both genders think it is the man's duty to provide for the family, the support rate for this statement among male participants is significantly higher, at 71.2%, and statistical differences can be detected (p=.000). While the "male politicians are more successful" statement is accepted at higher rates, at 49.7%, among male participants, statistically, there are huge differences between genders (p=.000). Conclusions: According to the research conducted, it is seen that traditional understanding weighs heavily, and the roles attributed to men and the perception of masculinity draw more attention. The fact that the research was conducted in a rural society where traditional understanding was dominant, substantially affected the results. The perspective of rural societies needs to change. Raising and increasing awareness on topics, such as gender roles, gender perception, and human rights with the health education method will be effective in changing the perceptions of men and women about one another.

How Did Donald Trump Turn the Republican Party into the People's Party?

The accepted working assumption on the eve of the 2020 Presidential Election in the US was that his image, as well as the perception that he holds negative opinions regarding immigrants and immigration while supported by white supremacists, would result in voters casting their ballot based on racial or ethnic considerations to vote against him. This paper was aimed at examining that linkage, to see if it took place in reality, or rather if voting needs to be looked at as a choice made based on class and stature, not racial background. To examine the issue at hand, 2016 voting patterns were compared to 2020 exit polls based on racial background. The findings showed that support for President Trump rose across all races, sometimes more than doubling. At the same time, votes were analyzed based on a breakdown by class. For the study, three batches of districts were chosen: the poor of America, the average of America, and the rich of America. One district was chosen from each state, and a total of 147 districts from across the US were looked at. The research shows that as one climbs the social ladder, support for President Trump declines. Or, in the context of this paper: the lower one is on the social class ladder, especially among the ‘forgotten’ periphery, the higher the approval and support rate of President Trump is.

Public Support for the Death Penalty in China: Less from the Populace but More from Elites

This article is the first to report the nationwide public support rate for the death penalty in China. Using a national representative sample with 31,664 respondents, it shows that 68 per cent of China's citizens are for the death penalty, while 31 per cent are opposed to it. These numbers suggest that support for capital punishment in China, although strong, is much weaker than in some other East Asian jurisdictions and less than first assumed by commentators. However, contrary to previous notions that public support for the death penalty derives from uninformed popular prejudice, it is the elites in China – i.e. those who receive higher education – who are more in favour of the death penalty. Further empirical analyses suggest that this is not because of political ideology or fear of crime. Rather, the reason is likely that the elites know fewer, and sympathize less with, criminal offenders, who generally come from underprivileged groups. These findings challenge a range of prevailing perceptions of public attitudes to the death penalty in China, especially the culture explanation for the Chinese public's punitiveness, and have important policy implications.

Analysis of motivational factors, possible deterrents and actualities about blood donation in Zimbabwe

Background: Blood is a body fluid responsible for transportation of nutrients, oxygen and metabolic waste. It is a non-pharmaceutical product obtained through voluntary donations. Blood transfusion is very important in the health system of any nation. Patients who are in need of blood donation expect the availability of adequate blood to satisfy their demands. Nevertheless, this is not so, mainly in third world countries like Zimbabwe where less than 6 people donate blood per 1000 populace. We need to deeply understand motivators, possible deterrents and available blood donor knowledge in order to have adequate regular voluntary non-remunerated blood donors. Methods: A cross sectional study of donors incorporating purposive sampling technique was used and a sample size of 465 was used. A self-administered questionnaire was used where donors were rating importance of: factors that motivate or deter their interest to donate blood and rate their blood donation knowledge. Statistical methods were used for reliability and correlation tests. Results: Most of the 465 participants were 1st time donors262(56.3%) and 203(43.7%) had some donation history. All donors endorsed that there exist factors that motivate them to donate blood which included the desire to help someone in need 386 (83%), good attitude of staff 419 (90%), reminders to donate381 (82%) and donor incentives 409 (88%) with their corresponding response rate. Six out of the nine suggested deterrents were endorsed as significant deterrents to blood donation. The corresponding support rate for each deterrent are absence of incentives 529(82%), poor attitude of staff 363(78%), myths and beliefs, 330(71%), feeling bad after donation, 251(54%) and the belief that blood will be sold 330(71%). Most people did not know the minimum age to donate blood as only 54 (11.61%) and only 168(36.13%) knew the correct interval between donations which should be 4 months. Only 171(36.77%) knew that blood expire. Conclusion: Our findings suggest that more donor drives needs to be taken educating people on blood donation, motivating donors to donate whenever there is blood shortage. Young donors are more attracted to concrete items as incentives and females donate more than males. Attitude of staff can motivate or demotivate donors to continue with this altruism gesture.

MWPoW: Multiple Winners Proof of Work Protocol, a Decentralisation Strengthened Fast-Confirm Blockchain Protocol

Blockchain mining should not be a game among power oligarchs. In this paper, we present the Multiple Winners Proof of Work Protocol (MWPoW), a mining-pool-like decentralised blockchain consensus protocol. MWPoW enables disadvantaged nodes which post only a small amount of calculation resource in the mining game to create blocks together and compete with power oligarchs without centralised representatives. A precise Support Rate of blocks can be determined through the mining process; the mechanism of the mainchain determination is therefore changed and has become faster and more straightforward. A method that periodically adjusts the block size and the block interval is introduced into MWPoW, which increases the system flexibility in the changes of network conditions and data flow. Experiments suggest, without lifting calculation and bandwidth requirements, MWPoW is more attractive to disadvantaged nodes due to its mostly increased reward expectation for disadvantaged nodes. The transaction pending time is shortened chiefly, and either the block interval or the block size can be adapted amid the changes of overall network conditions.

The study aimed to identify the impact of the supervisors' reluctance to participate in the Education Excellence Award and also to identify the reasons that led the supervisors to refrain from participating in the Education Excellence Award, in addition to discovering ways to motivate supervisors to participate in the Education Excellence Award, The study used the descriptive survey methodology, The research sample consisted of (17) supervisors from the Tbbala Education Office of the Bisha Education Department, The study concluded: 1- There is a significant impact of the reluctance of supervisors to participate in the award of the Ministry of Education for excellence on the quality of institutional performance with a support rate of 79.06%. 2- The reasons for the supervisors' reluctance to participate in the education award for excellence were largely with 70.59% support. 3- Ways to motivate the supervisors to participate in the education award for excellence was highly and with the support of 82.35%. In light of the results, the study recommended that the supervisors should be motivated to participate actively in the Excellence Award with a committee evaluating the work and providing feedback.

Homology bioinformatics analysis of IPA1 gene in higher plants

IPA1 gene controlled paddy has increased in height, sturdy stem, number of tillers decreased, grains per panicle and dry grains weight increased significantly. In this study, the homology of IPA1 gene in 26 types of plant from 15 families was analyzed, and thus constructed its phylogenetic tree. The results of phylogenetic tree construction based on its amino acid sequence showed that the species from the same family, such as Gramineae, Rosaceae and Palmaceae, were well clustered for different branches and had high support rates. Furthermore, we constructed the phylogenetic tree based on its CDS sequence, and the species of Gramineae was well clustered, and the support rate was 100%. Our results indicate that IPA1 has high homology in higher class of plants, especially in the Gramineae, which is of great significance for us to further study the yield of rice and other gramineous species.s with time and concentration effect (3) Achilla glauca extract could make the chromosome bridge, chromosome fragment, chromosome lag in the root tip cells of Vicia faba and increase in micronucleus rate. The results showed that the water extract of Solidago canadensis had different degree of inhibition and damage to silkworm root tip cells; it also had some genetic toxicity and rapid diffusion ability.
