Bulls and Bears and Bankruptcy- An Early Warning of Distress.
Authors: Bertuah Eka , K. Ghani Erlane
Published: June 2019

This study examines possible indicators of financial distress: financial ratio; financial decision; the preferences of investors; and economic macro conditions. Based on these indicators, the model of financial distress was constructed using capital structure theory. The population in this study is manufacturing companies listed on The Indonesian Stock Exchange from 2003 to 2016. This study relies on the composite market index to detect whether the market is bullish or bearish using regression analysis time series. Then, the factor analysis and logistic regression are used. Models which predict financial distress in bearish markets are more accurate than in a bullish market. Investors, therefore, are more vulnerable ina bullish market. Equity financing will reduce the probability of financial distress in both bullish and bearish markets. This supports the pecking order theory in capital structure - when the companies need funding, an early funding alternative is to retain earnings.

Published: June 2019

The deployment of Enterprise Resource Planning (ERP) systems worldwide has become an evidence of the unprecedented movement towards integration of information technologies. The importance of continuance usage during the post implementation stage should not be neglected as to secure an optimal advantages offered by ERP system, that is achieved through minimizing ERP system usage barriers. As such, successful implementation of an ERP system does not necessarily guarantee that the system will be comprehensively used or accepted by users of the system. ERP benefits can only be realised and sustained if users continue to have favourable experiences in using the system. While many previous studies have examined ERP system during the implementation phase, only a few have revealed barriers to ERP usage as well its antecedent factors during the post-implementation phase. The purpose of this paper is to determine ERP system usage barriers and unearth the root causes to the barriers. To achieve the aim, this research was guided by the ‘soft-positivism’ paradigm, a paradigm that combines elements of positivism and interpretivism. By using this paradigm, the investigator brought certain prior expectations to the data analysis which are consistent with positivist research and which also build rich explanations from the data, consistent with the interpretive assumption. Based upon the lens of Task Technology Fit theory, this study adopts a qualitative method using multiple case studies. Three Malaysian organisations that had implemented ERP were investigated by conducting 30 semi–structured interviews and reviewing archival records and documents. The interviews were guided by the research objectives. Data were analysed by using open and thematic coding.The finding indicated four major areas of ERP usage problems: system, data, and technical infrastructure and interface problems. Besides that, several antecedent factors to the problems were identified. These factors fall into four major categories: organisation, user, task and technology, and include lack of support from either external or internal expertise, lack of individual strength and limited technology affordance. The outcome of this study was encapsulated in the form of the ERP Sand Clock Barriers and Antecedents Model.The paper contributes to post-implementation ERP system literature by stressing the complex relationships between usage barriers and antecedent factors. By identifying the underlying causes of SAP usage barriers, it could become the motivating factor for individual users to undertake reflective feedback and to achieve extended use of the implemented ERP system.
Understanding the Nexus of Climate Change and Migration: A Case of Dhye Peoples from Upper Mustang, Nepal
Authors: Sherchan Pragya
Published: June 2019

People of Dhye village are recognized as the Nepal’s first climate refugees. Historical records show that mass migration of people from Dhye village has occurred for three times, with latest one attributed to the climate change. This article aims to explore and understand the underlying causes of the Dhye people’s migration, and to analyze the land suitability for their relocation. The article discusses that people of Dhye have migrated mainly to look for livelihood options, water availability and land for cultivation. As of now, more than two dozen water ponds have dried completely, and the only community reservoir serves as main source of irrigation water. This led to a decrease in cultivated area by one-fourth within last 40 years. The livestock farming has also been decreasing year by year with only one yak herder left in the entire Dhye village. The temperature trend is positive, whereas precipitation trend is negative. The land suitability analysis done by using Multi-Criteria Decision Analysis (MCDA) shows that Thangchung Chawale village is more suitable location than Dhye village in terms of cultivation area, water availability, and distance to health-post and transportation facilities.

Construction Practices in Karachi Featuring Town Wise Study: Non-Compliance of Safety Measures and Consequences
Authors: Jafri Syed Faraz , Sheeraz Khawaja , Rao Zubair Iqbal , Pirzada G. B.
Published: June 2019

Based on the statistical evaluation of accidents, the construction industry on an overall basis is full of dangers and risk oriented. The natures of the activities involved become hazardous when compliance with the safety rules and regulations are not properly followed, as a result high rates of accidents occur on the construction sites. In the metropolitan city of Karachi, Pakistan, a poor safety record has been observed in the construction industry. The primary reason existing for this situation is a non-preventive construction safety practice during execution of the projects. The secondary causes are dependent on the lack of resources, skills and interest of the concerned public sector agencies in enforcing the safety protocol regulations for the construction sites. In-addition, this situation also arises due to the lack of training in construction practices, child labor and a minimum awareness about the safety rules and regulations concerned with working on the construction sites.

This necessitated a need to embark on a program of collecting data in connection with the accidents occurring on construction sites in Karachi; a six months program involving Construction Site Accidents (CSA) was accomplished. This involved different districts of Karachi region to be included in this study. In particular, CSA contributory factors relating to skilled, semi-skilled, and non-skilled labors were evaluated and marginalized. Through this study, it will be shown how by properly implementing the safety and operational measures, based on statistical conclusions, the rate of accidents can be significantly reduced.

Authors: Степанова Галина , Stepanova Galina
Published: June 2019

The influence of weather conditions in the autumn-winter period and in the growing season on the content of crude protein, crude fiber and crude fat in the dry matter of alfalfa (Medicago varia Mart.) in the flowering phase has been studied. It was found that if during the formation of alfalfa herbage weather conditions were such to the average annual, the content of crude protein was 17.1–20.6%, crude fiber 24.5–28.6% and crude fat 2.4–3.3 percent. In conditions of sufficient moisture supply, increased heat supply and the predominance of Sunny days, the protein content reached to 18.9–24.8%, fiber was 19.0–23.0%, fat was 1.7–2.4 percent. With high heat and moisture with a predominance of cloudy weather, the protein content decreased to 15.0–17.7%, fiber increased to 35.4–39.3%, fat – to 2.6–3.5 percent. It was found that excessively wet weather in the autumn-winter period of the previous year significantly weakens alfalfa plants. Therefore, the beginning of spring regrowth, even in warm weather in April, was delayed for

1–2 weeks. The intensity of growth and development of alfalfa in May–June, even with optimal heat and moisture, was slow. The entry of alfalfa into the flowering phase was late by an average of 2 weeks compared to normal dates. At the same time, the content of crude protein decreases to 12.4–15.0%, the content of crude fiber increases to 32.1–34.4%, and the content of crude fat (2.4–2.9%) was not affected by unfavorable wintering conditions. It was found that the relatively high quality of dry matter in the flowering phase (average for 4 years of use) have varieties Vega 87 and Taisia (protein content of 18.3 and 19.5%, fiber 29.3 and 29.2%, fat 2.7 and 3.0%). Performance of alfalfa varieties to Pastbishchnaya 88 and Selena was a 15.9%, 30.9%, 2.3% and 17.3%, 28.8 %, 2.7%, respectively.
Influence of abiotic factors on seed productivity of red clover (Trifolium pratense L.) in subarctic conditions of the Russian Federation
Authors: Корелина Валентина , Korelina Valentina
Published: June 2019

Field experiments on sod-podzolic medium-loamy soil typical for the Northern region of the Russian Federation were carried out to identify the dependence of seed productivity of red clover varieties on

abiotic conditions. Meteorological conditions during the years of research (2012–2018) were different and had a significant effect on seed productivity of clover. It is established that the seed productivity of red clover has a positive correlation with the temperature regime and a negative relationship with rainfall, which indicates the possibility of seed growing of this culture in the study zone. However, seed yield varied considerably from year to year and ranged from 96 to 403 kg/ha. The reasons for the reduction of seed production in some years were varied and complex. As a result of researches it is revealed that for formation of productivity of seeds of a clover more than 150 kg/ha conditions are necessary: sum of effective temperatures above 1400 °С, the hydrothermal coefficient less than 1.6. From 7 years of research conditions close to those in the Northern zone of clover sowing were 57%. The most plastic samples by seed productivity were selected: Taezhnik, K-44933, K-48009, K-1809, K-1040.

Ischemic bowel disease results from an acute or chronic decline of the blood supply to the bowel and may have various clinical presentations, such as intestinal angina, ischemic colitis (IC) or intestinal infarction. Elderly patients with systemic atherosclerosis who are symptomatic for the disease, congestive heart failure and recent aortic or cardiopulmonary bypass surgery are particularly at risk. The clinical evolution and outcome of this disease are difficult to predict because of its polymorphic aspects and the general lack of statistical data. In this paper, we present two cases of patients who were monitored in our clinic. For these patients, we encountered with pivotal changes in the clinical pattern. These evolutions is particularly rare in common clinical practice, and cases are exemplary because it raises discussions about the nature of the condition and therapeutic decisions that should be made at every stage of the disease.

The aim of the study is evaluation of effectiveness of this procedure. METHOD. From Jan 2013 to Dec 2015 40 patients with anal fistulae, exciting more than 30% of anal sphincter was included in the study. Male: 28 (70%), Female: 12 (30%). 29 (72,5%) cases were middle transsphincteric, 16 (22,5%) - deep transsphincteric and 2 (5%) was suprasphincteric. RESULTS. The median follow up was 16 months ((3-36) months). The healing rate was (72,5%). Recurrents developed in 5 (17,3%) patients with middle transsphincteric fistulae, 5 (55,6%) - with deep transsphincteric fistulae, and 1 (50%) with suprasphincteric fistulae. 4 patients developed an intersphincteric abscess. After excision of this fistulae healing occurred in all four cases. A second operation did not affect the function of anal continence. At follow-up there was no change in continence evaluated by Wexner score and anorectal manometry. CONCLUSION. LIFT has a high success rate in middle transsphinteric anal fistulae. Recurrence is related to deep portion fistulae or suprasphinteric fistula tract.

Published: June 2019

AIM of this study was to improve treatment outcomes for early rectal cancer; to assess the accuracy of endorectal ultrasound (ERUS) in preoperative staging of early rectal cancer. MATERIAL AND METHODS. A total of 42 patients of the main prospective group with early rectal cancer underwent transanal local excision (LE). In control retrospective group 39 patients underwent radical resection with total mesorectal excision (TME). Operation time, perioperative, hospital stay duration long-term oncological results (overall and local recurrence-free survival, cancer-free survival, distant metastasis rate) were analyzed.. Comparison of ERUS preoperative staging for prospective group and pathological staging was performed to identify the accuracy of ERUS. RESULTS. Median follow-up for prospective group was 41 (from 10 to 60) months. In comparison with TME, LE was associated with fewer morbid (4,8 % vs 17,9 %, p=0,04). There was no hospital mortality in both groups. The accuracy of ERUS was 88,1 % for Tis and 78,6% for T1. There was no significant statistical difference in 1-year and 3-year in oncological outcomes between groups (p=1,0). There was one local recurrence (2,6%) in 6 months after LE in a patient with pT1sm3 who had previously refused surgery. This patient underwent TME. There was no detected distant metastasis in both groups. The 3-year overall survival was 100 % for LE and 97,4 % for TME. The 3-year cancer-specific survival was 100 % in both groups. CONCLUSIONS. LE has advantages over TME in short-term results; long-term oncological results after LE are comparable with TME. ERUS has a good diagnostic effectiveness in preoperative staging of early rectal cancer.

Published: June 2019

INTRODUCTION. About 75% of patients with Crohn's disease (CD) required surgery due to the complications of CD. Surgical treatment does not cure this disease. The question of appropriate therapy for the prevention of postoperative reccurence of CD remains open until now. The purpose of this study was to compare immunosuppressive and biological therapy as a postoperative preventive therapy. MATERIALS AND METHODS. 91 patients with CD who underwent surgery in the A.N. Ryzhykh State Scientific Center for Coloproctology of the Ministry of Health of Russian Federation from 2010 to 2017 were included in the study. Patients who had inflammation in the remaining areas of the intestine in the outcome of surgical treatment were excludedfrom the study. After surgery, patients were randomized into 3 groups. In the first group preventive therapy was carried out with azathioprine, in the second group with adalimumab, in the third group, patients received combination therapy with azathioprine and adalimumab. Clinical, endoscopical and laboratory assessment of disease activity was conducted at 3, 6 and 12 month after the surgery. RESULTS. During one year of preventive therapy with azathioprine, adalimumab, or a combination of this medications, relapse occurred in 17 patients (17/83, 20%). There were no statistically significant differences between the groups in any of the stages of evaluation. CONCLUSION: The data obtained in the study allow to conclude that the frequency of relapses of CD on postoperative preventive therapy does not depend on the specific drug, as well as on demographic and anamnestic parameters.

OBJECTIVE. To study the effect of active extracellular substances of lactobacilli and antimicrobial agents on the inhibition and destruction of the biofilms formed clinically relevant microorganism strains. MATERIALS AND METHODS. The study of the impact of different agents on the biofilmformation and growth was carried out on resistant clinical strains of microorganisms obtainedfrom patients with post-surgical infectious inflammatory complications. We used wound dressing solution, cutaneous antiseptic, filtrates of 19 clinical strains of lactobacilli and a strain of Lactobacillus plantarum from the probiotic «Lactobacterin dry» (Microgen Nizhny Novgorod, series 46 / 06-1209) as a reference strain-producer of bacteriocins for biofilm inhibition. Biofilms were incubated for 48 hours on glass carriers at 37°C and visualized with a light microscope at 960x magnifying. RESULTS. All substances possess a good inhibitory potential and have approximately same level of effect. The skin antiseptic and wound washing fluid have only an inhibiting effect on the biofilmformation process, while the having a bactericidal effect on plantonicform of the cells. The lactobacilli filtrate inhibited the biofilmformation and was also able to destroy preformed 24-hour bacterial films. CONCLUSION. The use of lactobacilli bacteriocins can reveal additional opportunities for combating the infection associated with biofilm forming microorganisms.

AIM: to evaluate changes of anorectal manometry parameters and clinical symptoms of fecal incontinence 3 months after fistulectomy with primary sphincteroplasty. MATERIALS AND METHODS: fifty-two patients (37 males) with complex anal fistulae of cryptoglandular origin underwent fistulectomy and primary sphincteroplasty. The fistulas were recurrent in 13 (25 %) cases, 8 (15,4 %) patients had preoperative fecal incontinence. Fecal incontinence Wexner score was 0,46 (0-8) before surgery. Anorectal manometry was performed before and 3 months after surgery. RESULTS: three months days after surgery mean and maximum resting anal pressure were not significantly low compared with the baseline. In patients with initially normal data before the surgery (n=22), resting anal pressure was significantly lower (before surgery M=56,1 ± 7,6 [46,1-69,0], after surgery 45,5 ± 8,8 [38,0-63,0], p=0,006, Wilcoxon test). There were no significant changes in squeezing anal pressure. Resting anal pressure has become below the normal after surgery in 13 (59.1 %) patients. Clinical symptoms of fecal incontinence was detected in 10 patients postoperatively (gas incontinence and soiling). Fecal incontinence Wexner score was 1,64 (0-11) after surgery (p=0,007). CONCLUSION: fistulectomy with primary sphincteroplasty leads to change of resting anal pressure basically in patients with initially normal pressure and mainly - in patients with anterior fistulas. Fecal incontinence symptoms after with surgery produced 26,3 % patients. These data confirm the need of individual approach when choosing the method of surgical treatment of analfistulae.

AIM: to evaluate the efficacy of new «invaginative» method for rectovaginal fistulas. MATERIALS AND METHODS: thirty-seven females aged 37.3 (20-73) years with high rectovaginalfistulas (RVF) were included in the study. All patients underwent fistula surgery using novel «invaginative» method, which includes invagination of the fistula tract into the rectum, RVF origin included inflammatory bowel diseases in 7 (18.9%) patients, delivery injury - in 21 (56.7%), pelvic surgery - in 5 (13.5%), other causes - in 4 (10.8 %). Twenty (54.1 %) patients had two previous unsuccessful repairs on average. Diverting stoma formation as a first stage for RVF repair was performed in 4 (10.8%) patients. Meanfollow-up was 14,7± 6,6 months. RESULTS: «invaginative» method has been performed in all patients. Eight (21.6 %) of them produced recurrence after 2-6 weeks after surgery. No postoperative complications occurred. CONCLUSION: «invaginative» method is a safe and effective in treatment of high rectovaginal fistulas. It can be performed without diverting colostomy in most cases.

AIM: to evaluate the effecacy of laser submucosal destruction using a radial light guide in patients with chronic hemorrhoids (stages II and III).

PATIENTS AND METHODS: the study included 65 patients with chronic hemorrhoids, 20% had stage II and 80% – stage III by Goligher classification. Laser submucosal destruction of hemorrhoidal piles has been performed in all patients. The following criteria of assessment were used: pain intensity by visual analogue pain (VAS) scale, the morbidity rate and the time complete wounds healing. Criteria for late results assessment was the severity of the main symptoms of hemorrhoidal disease like piles prolapse, bleeding, thrombosis and anal itching.

RESULTS: in 54 (83.1%) patients the postoperative period was uneventful. Postoperative pain syndrome was 3±2 points on VAS scale. Minor postoperative complications were detected in 11 (16.9%) patients. No recurrent hemorrhoids occurred in follow-up.

CONCLUSION: laser submucosal destruction is a good alternative for HAL-RAR and STARR procedure for hemorrhoidal disease, when the rubber band ligation and sclerotherapy were ineffective but the time for classical hemorrhoidectomy has not yet come.

Published: June 2019

In this study, the issues of complicated interactions between process variables were solved by decoupling techniques; in particular, simplified decoupling was used due to its simplicity and robustness. A new approach to solving decoupling realizability was developed by using the modified particle swarm optimization (PSO) algorithm. However, time delays still existed in the diagonal elements of the decoupled matrix, and they resulted in a more sophisticated controller design and sluggish responses in the outputs. To overcome the adverse effects of time delays, a Smith predictor, also known as a dead time compensator, is normally used. In this work, a Smith predictor structure in combination with simplified decoupling for multivariable processes was proposed in order to enhance system performances in terms of the servomechanism problem. The proportional integral or proportional integral derivative (PI/PID) controller tuning rules for several common industrial processes, such as first-order, second-order, and second-order with negative zero systems, were obtained. Many multivariable industrial processes were adopted to simulate the effectiveness of the proposed method in terms of the servomechanism problem and robust response.

Alpha lipoic acid (ALA) is a well-known anti-aging compound. The activity of this molecule is limited by two important factors: (i) The low stability to oxidation and thermal processes and (ii) the low solubility. Particularly the latter limits ALA formulation in hydrophilic bases. The purpose of this paper is to present a new technological approach to stabilize lipoic acid in topical hydrogels for cosmetic use. With this aim, ALA was intercalated in two different lamellar anionic clays (hydrotalcites), MgAl and ZnAl, obtaining the hybrids MgAl-ALA and ZnAl-ALA. The intercalation allows to obtain a more manageable product in comparison to raw ALA. After the preliminary characterization, hydrogels containing the hybrids were prepared and characterized, also in comparison to the commercial product Tiobec® in terms of rheological properties, stability to temperature and centrifugation, release, and cytotoxicity. The obtained results highlighted that the hydrogel containing MgAl-ALA is a suitable alternative to the products currently available on the market.
The Counternarrative of Teacher Evaluation: The Kangaroo Court, the Salem Witch Trials, and the Scarlett Letter
Authors: Smith Allison
Published: June 2019

The purpose of this sequential transformative study was to elucidate the negative experiences of teachers with performance evaluations and to juxtapose the intended use of current popular teacher evaluation reform movements to the evident implementation. One may quickly assume that negative experiences with evaluation are a result of unsatisfactory teaching practices. However, this may not accurately explain the negative experiences. This study focused on the negative experience of teacher evaluation to provide a broader understanding of the impact of new evaluation policy reform on student achievement and teacher quality. With a paucity of previous research focused on the negative impacts of teacher evaluation, this study addressed the following questions: (1) How does the Peer Assistance and Review (PAR) teacher evaluation process negatively impact teachers? (2) What, if any, parallel traits exist among those teachers who had negative experiences with the PAR evaluation system? and, (3) How does the intended use of the PAR teacher evaluation process compare to the evident use of PAR? Data revealed dissonance among intent and evident use of the evaluation policy. A disproportionate number of African Americans, women over the age of 55, and teachers higher on the pay scale were referred to PAR. Vague policy language was suggested as the impetus for misuse, abuse, and biased implementation at the local level. This study suggests that policymakers and school district officials take heed of multiple perspectives and consider the negative impacts of teacher evaluation reform. Evaluation systems that prioritize teacher learning over accountability are integral to successfully improving student achievement.

This investigation was carried out to highlight the influence of the variation of permeability of the porous media with respect to the injection orientations during enhanced gas recovery (EGR) by CO2 injection using different core samples of different petrophysical properties. The laboratory investigation was performed using core flooding technique at 1300 psig and 50 °C. The injection rates were expressed in terms of the interstitial velocities to give an indication of its magnitude and variation based on the petrophysical properties of each core sample tested. Bandera Grey, Grey Berea, and Buff Berea sandstone core samples were used with measured permeabilities of 16.08, 217.04, and 560.63 md, respectively. The dispersion coefficient was observed to increase with a decrease in permeability, with Bandera Grey having the highest dispersion coefficient and invariably higher mixing between the injected CO2 and the nascent CH4. Furthermore, this dispersion was more pronounced in the horizontal injection orientation compared to the vertical orientation with, again, the lowest permeability having a higher dispersion coefficient in the horizontal orientation by about 50%. This study highlights the importance of the permeability variation in the design of the injection strategy of EGR and provides a revision of the CO2 plume propagation at reservoir conditions during injection.

This paper reports the effects of alternate axis twisted baffle geometric parameters on the heat transfer and flow characteristics within rectangular channels. In our experiments we used modified shapes of alternate axis twisted baffles according to relative pitch ratios (s/w) equal to 2–12 and twist ratios (y/w) equal to 1–5, under conditions where the angle of attack (α) was 90° and the relative blockage height (e/Dh) was at a constant value of 0.095. The results for the Reynolds numbers based on the duct hydraulic diameter ranged from 9000 to 24,000 at a constant Prandtl number, Pr = 0.707, using air as a working fluid. A 0.05 mm thick stainless-steel foil was used as a heater, and a thermochromic liquid crystal technique was used to obtain the local temperature distribution on the heated surfaces. Images were captured in areas with periodic, fully developed regions in the channel. The results show that rectangular channels equipped with alternate axis twisted baffles demonstrated 80%–185% greater heat transfer than rectangular channels with no baffles. Channels with alternate axis twisted baffles at higher twist ratios (y/w) and smaller relative pitch ratios (s/w) showed increased heat transfer, as well as pressure loss within the system, compared with other types of twisted baffles. The thermal enhancement factor of the rectangular channels equipped with alternate axis twisted baffles was higher than that for transverse baffles and smooth channels under similar operating conditions.

In recent years, municipal solid waste (MSW) management has become a complex problem worldwide. Similarly, Mexico City is facing such a situation for the management and treatment of organic fraction of municipal solid waste (OFMSW). Therefore, in this work, we investigated whether leachate from the composting plant, Bordo Poniente, located in Mexico City can be used as an inoculum for the treatment of OFMSW using thermophilic anaerobic digestion (AD) with a hydraulic retention time of 30 days. We analyzed the physicochemical properties of the leachate and performed a biochemical methane potential test. Archaeal and bacterial diversity was also identified using high throughput DNA sequencing of 16S rDNA libraries. Methane yield was 0.29 m3 CH4/kg VSadded in the positive control and 0.16 m3 CH4/kg VSadded in the treatment group. The phylum, Bacteroidetes, and genus, Methanosarcina, prevailed in the leachate. However, in thermophilic conditions, the microbial communities changed, and the phylum, Firmicutes, genera, Methanoculleus, and candidate genus, vadinCA11, were dominant in the treatment group. We concluded that the leachate contains a suitable initial charge of many active bacteria and methanogenic archaea which contribute to the AD process, hence it can be used as an inoculum for the treatment of OFMSW.

Experience shows that under unidirectional wind or certain terrain, the surface of post insulators is non-uniformly polluted between windward and leeward sides, which affects the flashover characteristics. In this paper, a formulation of residual pollution layer resistance was proposed under this non-uniformity and a typical post insulator was taken as an example to analyze and calculate its residual resistance. The theoretical resistance was verified by numerical simulations using COMSOL Multiphysics. The proposed resistance formulation was then implemented in a DC flashover dynamic model to determine the flashover voltage (Ucal), which was validated by artificial flashover tests. Then the factors affecting DC flashover voltage were analyzed. Research results indicate that: the residual resistance formulation agrees well with simulation results, especially when the arc length exceeds 70% of the leakage distance. The good concordance between theoretical and experimental flashover voltages with most relative error within ±10%, validates the flashover model and its residual resistance formulation. Ucal gets impaired under this non-uniformity. The degree of reduction is related to salt deposit density ratio (m) of windward to leeward side and leeward side area proportion (k).

Published: June 2019

For a single-stage variable-pitch axial fan, the aerodynamic performance and through flow with and without blade skewing are examined numerically. Simulated results show that the total pressure rise and efficiency increase by 2.99% and 0.16%, respectively, with the best forward-skewed angle of θ = 3° at the design conditions. At the blade pitch angles of β = 29° and 35°, the total pressure rises and efficiency of the fan with θ = 3.0° under the highest efficiency point change by −0.55%, −0.53% and 1.39%, 2.11%, respectively. At design and off-design conditions, the forward-skewed blades mitigate tip leakage and delay the emergence of separation flow at the blade root, these benefits are higher at the higher blade pitch angle. The θ = 3.0° forward skew effectively raises the stage performance of the impeller and guide vanes.
