Power boiler’s fly ash fineness as an parameter determining the usability in concrete industry

In relation to the new emission restrictions for power units a combined firing of coal and biomass is widely used in power boilers. The new fuel entails new boiler operation conditions suggesting that there should be performed a new research including the detailed analysis of the combustion by-products. One of the combustion by-products is fly ash, which can be successfully applied in building materials like concrete. The classification of fly ash according to the parameters like fineness allows to use the fly ash as a partial substitution of cement in different types of concrete. This paper presents an analysis of the fly ash fineness determined by the wet sieving method. The obtained results demonstrate the changes of fly ash fineness in a separate sections of an Electrostatic Precipitator (ESP), what lead to a conclusion that not all of the collected fly ash fulfil the requirements of the standard BS EN 450-1 + A1: 2007. Addition of fly ash in cement influences composition, chemical and physical parameters of concrete, what makes this combustion by-product valuable. Furthermore, its usage is beneficial from the point of view of CO2 emission and utilisation of combustion residues.
Post Surgical Non-tuberculous Mycobacterium: A Case Series

Background There has been an increase in non-tuberculous mycobacteria (NTM) infection reports in humans. Surgeons are concerned about the link between them and surgical site infections. As a result, it has been challenging to determine just how common this illness is. A two-year study by the authors examines the occurrence of NTM infections after different surgical procedures. Design and methods Researchers at a tertiary care hospital in central India performed this prospective study over two years. NTM was found in six of the 25 instances of post-surgical wound infections. Ziehl-Neelsen staining, Auramine O-Rhodamine fluorescence staining, Multiplex Real-Time PCR, and Genotyping were used to identify the species. Results M. fortuitum, M. chelonae and M.kansasii were isolated from discharge in 2 cases each respectively. NTM isolates evaluated for antibiotic susceptibility pattern were all sensitive to Clarithromycin (100%). One case with prolonged healing had to be intervened with amikacin along with clarithromycin. Conclusion NTM is an infection of uncommon nature which can occur following surgical procedures. Identification of these organisms through sensitive techniques and appropriate therapeutic regimen formulation must be done to tackle this growing menace in health care setups.
Investigating the relationship between food and alcohol disturbance and coping styles among young adults

ABSTRACT Background Food and alcohol disturbance (FAD) represents a phenomenon characterized by a range of dysfunctional eating behaviors individuals engage in when they plan to drink alcohol in order to compensate for alcohol-related calories. The aim of the present study was to investigate the relationship between FAD and coping styles among young adults. Methods The sample was composed of 379 young adults (274 females and 105 males) with ages ranging from 18 to 30 years who completed a survey online of self-report measures assessing FAD,alcohol misuse, compensatory behaviors and coping styles. Results FAD was positively correlated with alcohol misuse, fasting, use of laxatives and avoidance strategies and negatively correlated with turning to religion. Results from the hierarchical regression analysis indicated that alcohol misuse and avoidance strategies positively predicted FAD, while turning to religion was a negative predictor. Conclusion Our study highlighted that the use of strategies focused on avoiding distress arising from stressful situations may be a risk factor for engaging in FAD; conversely, turning to religion in times of difficult life circumstances seem to protect against FAD.
The Suitability of Global Rating Scales to Monitor Arthroscopic Training Progress

Purpose: As developing arthroscopic skills is challenging and training time for residents is limited, arthroscopic skill competency of residents should be measured. Assessment tools, such as Global Rating Scales (GRS), have been developed for structured, objective feedback and to assess learning curves. The goal of this study is to assess known-groups and convergent validity of these scales, to evaluate the suitability of these scales to monitor training progress of residents. Methods: Knee arthroscopies and ACL reconstructions performed by residents were supervised and assessed, using both GRS questionnaires. The estimates of the parameters were used to study the relationship between year of residency and each GRS score, and between the number of previously performed arthroscopies and each GRS score. Pearson correlation coefficient between GRS scores were calculated to measure convergent validity. A BlandAltman plot with a paired t-test was constructed to evaluate the agreement between GRS I and II. Results: Mixed model analysis revealed a significant increase (p < 0.001) per year of residency on both GRSs (8.1 points (95% CI: 6.3-9.9) and 9.2 points (95% CI: 7.4-11.2) respectively). Significant increases per performed arthroscopy were also observed for both GRSs (p < 0.001) (0.14 (95% CI: 0.09-0.18) and 0.13 points (95% CI: 0.08-0.2) respectively). Scores for ACL reconstructions were significantly lower (p < 0.001) than for standard knee arthroscopies (12.5 and 13.0 points respectively, p < 0.001). The Pearson correlation coefficient between GRS I and GRS II scores was high (0.94). The Limit of Agreement was 11 points. Conclusion: GRS I and GRS II demonstrate sufficient construct validity. However, they seem not sufficiently sensitive and consistent to establish individual learning curves. Both scales are suitable to objectively evaluate global progress of residents in the operating room when acquiring arthroscopic skills, in particular on group level.
The effect of terrorism on continuing education: evidence from Pakistan

ABSTRACT Education has wide-ranging benefits to both the individual and wider society. This article investigates the consequences of terrorist incidents on whether households can further their children’s schooling. Using both the Global Terrorism Database and Pakistan’s Social and Living Standards Measurement, we find that persistent exposure to terrorism significantly reduces the likelihood that parents will continue their children’s education. The result suggests, that for every million people, an increase in terrorist incidents causes 26,501 fewer children to continue their education at the primary school education level. We also examine the results by various demographic segments and types of terrorism attacks.
Associations between Ozone and Emphysema: A Systematic Review and Meta-analysis

Air pollution is widely viewed as a serious threat to human health and a contributor to deaths. Air pollution appears to be linked to the progression of emphysema, according to epidemiological data. The objective of this study was to examine associations between air pollution and the progression of emphysema using a meta-analysis. A meta-analysis was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) protocol. A systematic literature search was conducted using the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Embase, PubMed, and Web of Science bibliographic databases. A random-effects model for the meta-analysis was implemented to summarize effect estimates of sufficiently comparable outcomes and pollutants (e.g.: particulate matter, nitrogen oxides and ozone), and the results were visualized in forest plots. We observed that a 1-ppb rise in O 3 was associated with a 0.30 increase in the percent emphysema progression (95% CI: 0.02, 0.57, p < 0.05). In contrast, no significant association was found between PM 2.5 or NO 2 exposure and the percent change in emphysema. Increasing O 3 concentrations may have an impact on and exacerbate human health conditions such as emphysema and respiratory diseases. Air quality and climate change should be concerns for future environmental policies and protection measures.
Comparative Study Between The Efficacy of Ozone Gel and Hyaluronic Acid on Bone Healing After Enucleation of Mandibular Odontogenic Cysts

Aim: The aim of this study was to evaluate the clinical and radiographic effect of both Ozone gel and Hyaluronic acid after enucleation of mandibular odontogenic cysts. Subjects and methods: 24 patients complained of an odontogenic cystic lesion in mandible classified into three groups, Group I (Ozone group): Included 8 patients with odontogenic cysts treated by Enucleation followed by Ozone gel application in the surgical cavity. Group II (HA group): Included 8 patients with odontogenic cysts treated by Enucleation followed by Hyaluronic acid application in the surgical cavity. Group III ( Control group): Included 8 patients with odontogenic cysts treated by Enucleation only. Postoperative one-month panoramic view, 3, 6 cone-beam C.T as the radiographic follow-up. Facial edema, pain, and trismus were the clinical parameters at 1,3 and 7 days. Results: The study showed a significant increase in the bone density of both group I (ozone), II (Hyaluronic acid) than the control group comparing the percentage of bone density to the contralateral bone, it was for group I (Ozone group) 45.8%, 69% at follow up of 3,6, months. In group II ( HA ) it was for 51.9%, 72% at follow up of 3, 6, months. It was for group III (control group) 32.6%, 56.1% at follow up of 3, 6, 9 months as there was high statistical significance between-group I, II in comparing with the group I with P-value = 0.04,0.05. Conclusion: Both ozone gel and Hyaluronic acid can be considered to enhance bone regeneration after cystic enucleation due to their specific antimicrobial, anti-inflammatory properties, and increasing angiogenesis in the post-surgical cavities. Over 90% of maxillofacial cysts are odontogenic in origin that is considered to be the most common group lesion that affects the maxilla and mandible. Many odontogenic cysts are asymptomatic and may be found accidentally during radiographic examination. Kramer (1) defined the cyst as a pathological cavity containing fluid, semifluid or gaseous material. In the maxillofacial area, odontogenic cysts are lined by epithelium except for solitary bone cysts and aneurysmal bone cysts (2)
How Do Digital Market Platform Hosts Exercise Control Over Sellers?: Digital Market Platform Sellers Control

High speed connectivity, smart mobile devices, social media and rapidly-proliferating end-user applications have given rise to digital markets. This paper investigates how digital market hosts exercise control over sellers. We propose that findings from prior empirical studies informed by control theory in other contexts might not fully apply to digital markets, since these platforms are loosely-connected to participants. Our three-case study revealed that, similar to controllers in other contexts, digital market hosts do utilize a mix of formal and informal control mechanisms, yet their seller control portfolios also differ importantly from control portfolios in other contexts. This paper presents our study findings, considers questions arising from the findings, and provides a useful foundation for further research which can consider why digital markets entail challenges that give rise to novel control portfolios.
Breed-specific expression mode of the Wnt signalling pathway is involved in feather follicle morphogenesis between Anser cygnoide and Anser anser

ABSTRACT Feathers are important economic products. Anser cygnoide (AC) is superior in reproduction, growth and feather quality, while Anser anser (AA) has an advantage in feather yield. Understanding the development of feather follicles facilitates deliberate crossbreeding. Here, we compared feather follicles morphogenesis between AC and AA. Feathers and dorsal skin were sampled at multiple embryonic days to investigate feather phenotypes, feather follicle morphology and the expression of hub molecules (FZD4, β-catenin, LEF1, TCF4 and c-Myc) in the Wnt signalling pathway. We found a marked difference in plumage colour between the two breeds. Feather colour in AA has undergone a ‘black dorsum’ stage and cavity formation in AC was earlier. Furthermore, different trends in molecular hub expression helped explain the phenotypical and morphological differences: the upregulated Wnt signals in AC at E12 and/or E15, as well as in AA at E18, were associated with early epidermal placode formation and cavity formation in AC, also, related to the development of the secondary feather follicles and ‘black dorsum’ in AA. Summarily, breed-specific expression patterns of Wnt signalling pathway between AC and AA might participate in the shaping of breed-specific feather follicles morphogenesis and feather phenotypes. This work provides references for feather follicles development in geese.
Re-producing public space: the changing everyday production of outdoor retail markets

ABSTRACT In 2020, nation states across Europe restricted access to, and use of, public space to prevent the spread of COVID-19. As almost all public spaces in Europe were consequently affected by restrictive measures, so too did outdoor retail markets drastically change. Some had to close down completely, whereas others operated under the sway of severe limitations for traders and customers. By re-engaging with the work of the late Michael Sorkin, it could be argued that the effects of COVID-19 add another dimension to the “end” or “death” of public space. In this paper, we shift attention to the tactics and strategies of one category of public figures behind the everyday production of markets, the traders, to show that markets in Spain, the United Kingdom, Switzerland and the Netherlands did not simply stop functioning as public spaces. Rather, they took on different forms that extended spatially beyond their physical boundaries. These transformations allowed for the continuation of the social and political dimensions of public space.
Fatty acid profile and productivity variation during the growth of Dunaliella sp. under different photon flux densities and glycerol concentrations

Microalgae can accumulate lipids during the stationary growth phase, but little information is available about fatty acid profile changes during this phase to determine the best harvesting time in respect to lipid content. In this study, Dunaliella sp. was cultured in F/2 medium at three different photon flux densities (380, 226 and 8.2 μmol photon m-2 s-1) and three different glycerol concentrations (0, 10 and 20 g L-1). Samples were taken during the stationary phase to assess lipid content and fatty acid profile variations. Microalgal biomass production was higher at 380 and 226 μmol photon m-2 s-1 than at 8.2 μmol photon m-2 s-1 in accord to light limitation. The maximum lipid content (345.78 mg g-1) was achieved at 8.2 μmol photon m-2 s-1 and 20 g L-1 glycerol at day 12, similar to that achieved at day 9 (334.16 mg g-1). The maximum polyunsaturated fatty acid amount (65.30 μg mg-1) was achieved at day 7 of culture without glycerol addition, decreasing in proportion over time. So, the best conditions and harvesting time in respect to fatty acid quality would be at 380 μmol photon m-2 s-1 without glycerol addition and after 7 days of culture.
Is Online Peer Support Helpful in Widowhood? The Lived Experiences of Young Parents

With the technological development in general, grief support has now gained a foothold on the internet with a huge variety of offers for bereaved individuals. However, researchers disagree whether this is mainly helpful or unhelpful in grief. The aim of this article was to examine how spousally bereaved individuals with dependent children had experienced the use of an online peer support group following bereavement. To the majority of respondents (83%, n = 70) the group had been immensely helpful. Thematic analysis of participant responses to open-ended questions resulted in three different themes: Identification, Good advice, and Changes in group use over time. The study underlines a need for a renewed focus on how we organize the support for parentally bereaved families in Denmark, and in particular, how the access to information and sources of support following a loss are made available across the board. Finally, the results testify to the fact that online peer support in grief is a means of seeking support in its own right.
Oral Bacteria and Their Antibiotic Susceptibilities in Taiwanese Venomous Snakes

Wound infections after venomous snakebites are clinically important. Information regarding the nature and antibiotic susceptibilities of snake oral bacterial flora could support empiric antibiotic therapy. Wild venomous snakes were collected from southern Taiwan: a total of 30 each of Bungarus multicinctus, Naja atra, Protobothrops mucrosquamatus, and Trimeresurus stejnegeri; 3 Deinagkistrodon acutus; and 4 Daboia siamensis. The species and antibiotic susceptibilities of their oral bacteria were determined. Aerobic gram-negative bacteria, especially Pseudomonas aeruginosa and Proteus vulgaris, were the most abundant. Proteus vulgaris were more abundant in B. multicinctus, N. atra, and P. mucrosquamatus than in T. stejnegeri (40%, 43.3%, and 40% vs. 13.3%, respectively). The gram-negative species were less susceptible to first- and second-generation cephalosporins and ampicillin-sulbactam than to third-generation cephalosporins, fluoroquinolones, carbapenems, or piperacillin-tazobactam. The most abundant aerobic gram-positive species cultured was Enterococcus faecalis, which was more abundant in N. atra than in other snakes (p < 0.001) and was highly susceptible to ampicillin, high-level gentamicin, penicillin, teicoplanin, and vancomycin. Bacteroides fragilis and Clostridium species were the most common anaerobic bacteria. The anaerobic organisms were highly susceptible to metronidazole and piperacillin. As a reference for empiric antimicrobial therapy, third-generation cephalosporins, fluoroquinolones, carbapenems, or piperacillin-tazobactam can be initiated in venomous snakebites wound infections.
Ocular lesion due to congenital infections (Cytomegalovirus, Toxoplasmosis), diagnosis, treatment and followup: A prospective study in Tehran, Iran

Background: Intrauterine infections lead to involvement of various organs in fetus, including the eye. The aim of this study was to determine the frequency and clinical response of ocular lesions to specific drugs in infants with congenital Toxoplasma and cytomegalovirus infections. Methods: This historical cohort study was performed in the pediatric and ophthalmology department of Hazrat Rasool Akram Hospital in Tehran from October 2011 to November 2017. Patients included 78 infants with intrauterine infection (proven) and ocular involvement (cataracts, glaucoma, and retinitis). Infants who did not undergo additional and diagnostic tests, eye examinations, follow-up and did not receive effective treatment were excluded from the study. Three patients expired during the study. Finally, 37 patients (including 25 patients with cytomegalovirus and 12 patients with toxoplasma) were included to assess and the clinical response to ocular lesions was evaluated for one year Results: Of 12 cases with toxoplasmosis, 5 patients received complete treatment and 4 patients had appropriate clinical responses. Of 25 patients with CMV, 18 patients received complete treatment and 9 patients had appropriate clinical responses. Conclusion: Successful treatment will be obtained in near 80% of ocular toxoplasmosis, so anti toxoplasma treatment is recommended in all confirmed cases. About 50% of CMV infected cases (with hearing loss, ocular involvement) might respond well to antiviral therapy, We recommend anti CMV treatment in any age ( <2 years old) but it is not indicated in CMV infected cases with severe brain involvement.
Numerical simulation of unsteady cavitation in liquid hydrogen flows

An unsteady cavitation model in liquid hydrogen flow is studied in the context of compressible, two-phase, one-fluid inviscid solver. This is accomplished by applying three conservation laws for mixture mass, mixture momentum and total energy along with gas volume fraction transport equation, with thermodynamic effects. Various mass transfers between phases are utilised to study the process under consideration. A numerical procedure is presented for the simulation of cavitation due to rarefaction and shock waves. Attention is focused on cavitation in which the simulated fluid is liquid hydrogen in cryogenic conditions. Numerical results are in close agreement with theoretical solutions for several test cases. The current numerical results show that liquid hydrogen flow can be accurately modelled using an accurate inviscid approach to describe the features of thermodynamic effects on cavitation.
The use of a flocculant additive and its effect on biofloc formation, nitrification, and zootechnical performance during the culture of Pacific white shrimp Penaeus vannamei (Boone, 1931) in a BFT system

Biofloc technology is a culture system that intensively uses microbial communities. Most bacteria can form aggregates around organic or inorganic surfaces. The high adsorption capacity, surface area, and flocculant properties of clay minerals make these compounds good candidates to stimulate biofloc formation, increase bacterial biomass, and improve nitrification. The objective of this study was to evaluate the addition of clay minerals to biofloc formation and its influence on the microbial community, nitrification, and zootechnical performance of Penaeus vannamei cultivated in a biofloc technology system. Experiment 1 involved the following treatments: control (without adding clay minerals), 10, 50, and 100 mg L-1, applied daily in the water. The treatments in experiment 2 were: control without product and inoculum, control without product and with inoculum, 50 mg L-1 clay mineral without inoculum and 50 mg L-1 clay mineral with inoculum. Both experiments with a density of 400 ind m-3. NO2 levels, total suspended solids, turbidity, differed significantly (P < 0.05) between treatments in experiment 1 and zootechnical performance parameters, where higher flocculant concentrations negatively affected these indices. In experiment 2, statistical differences were verified for NH3 and NO2 concentrations and the proximate composition of the bioflocs (P < 0.05), the addition of the inoculum of bioflocs influenced these results. In summary, the addition of clay minerals influenced biofloc formation, proximal composition, and the zootechnical performance of the cultivated shrimp but did not affect the abundance of microorganisms and nitrification.
