Analysis of the time efficiency of skidding technology based on the skidders

Abstract The time efficiency and principles of ergonomics related to timber skidding are based on the time consumption per work cycle as well as on the time consumption per individual work operations. Regarding the demands on the environmental requirements and ever increasing cost of work, it is necessary to objectively evaluate the inevitable time consumption required for timber skidding using all technologies. The paper summarised the results of time studies for skidder technologies. The time study compares the time consumption and productivity of cable skidders and cable-grapple skidders, with the main focus on developing time prediction models. The main aim of the study was to objectify the skidder time consumption and establish the impact of production factors on the time consumption of partial work operations of skidders. Within the time study 231 work cycles were measured, and 53 snapshots of work day with using methods continual time study. The overall time consumption of the work cycle and gross production rate of the monitored cable and cable-grapple skidders is affected by the following production factors: the skidding distance, volume of skidded logs and number of skidded logs. The impact of individual production factors on the overall time consumption of the work cycle is different for each group of skidders. Non-operation times of the skidder operators’ shifts represent 24.6% with the highest part taken by the technical operation of the work place. The mean gross production rate of the monitored skidders varied from 33.3 to 6.91 m3 h−1.
Detection of Genital Mycoplasmas Infections among Infertile Females

Method: Duplicate genital Swabs for genital mycoplasmas were taken from two hundred and sixty-three infertile female patients between March 2011 and August 2012; the age range was 21 to 45 years. Agar plates were examined every 24-72 hours for the characteristic Ureaplasma and Mycoplasma hominis (M. hominis) colonies. Isolates were identified serologically as M. hominis or Ureaplasma urealyticum (U. urealyticum) by growth inhibition test (disc method).
Effect of split applications of oil cake on leaf nutrient contents, tree growth, and fruit quality in non-astringent persimmon trees

ABSTRACT Oil cake, widely used as an organic source of nutrients in horticultural production in South Korea, is a by-product when oil is extracted from various oilseeds. Split applications of oil cake were supplied to evaluate their effects on tree growth and fruit production in organic, non-astringent persimmon (Diospyros × kaki Thunb.) trees in 2009 and in 2010. Treatments included a single annual application of oil cake at 150 kg N ha−1 in April (single application), two applications in April and July (105 and 45 kg N ha−1, respectively; two-split application), or three applications in April, June, and August (60, 45, and 45 kg N ha−1, respectively; three-split application), as well as zero application of oil cake (control). All applications of oil cake significantly increased the amount of ground-cover vegetation compared to the control. The single and two-split applications increased soil organic matter (OM), K2O, CaO, and MgO concentrations, and cation exchange capacity to a soil depth of 0–30 cm in 2010. Oil cake applications increased soil porosity in 2010, as well as overall chlorophyll (SPAD values) and macronutrient concentrations in leaves in 2009 and 2010. Single and two-split applications stimulated water-sprout development, reduced the light intensity inside the tree canopy, and increased fruit drop. Fruit yield was higher in the two-split [24.7 metric tonnes (MT) ha−1] and three-split application trees (25.0 MT ha−1) compared to zero application control trees (19.8 MT ha−1) and single application trees (21.0 MT ha−1) in 2010. A single application resulted in soft fruit and slow skin colouration during maturation. Total soluble solids contents were higher in the control and three-split application trees in both years. The three-split application in 2010 increased the estimated production income by approx. 21% compared to the zero application, and by approx. 33% compared to a single application of oil cake.
Comparison of pain response to vein puncture versus heel lance among preterm infants undergoing blood sampling

Background Pain in neonates is largely underestimated and neglected. Accurate pain assessment is the first step toward effective pain management. Skin-breaking procedures such as heel lances, vein punctures, and arterial punctures are the most frequently performed painful procedures in neonatal ICUs. Few studies have been done to compare preterm infants’ pain response to heel lance vs venipuncture. Aim The aim was to compare pain response to venipuncture vs heel lance among preterm infants undergoing blood sampling. Materials and methods A comparative descriptive research design was used on a convenient sample of 60 preterm infants less than 37 weeks of gestation who were undergoing blood sampling for complete blood count, blood chemistry, or glucose estimation. Neonatal assessment sheet, blood sampling assessment sheet, and premature infant pain profile scale were used to collect data from two neonatal ICUs of both Cairo University Children Hospital (El Monira) and El Manial University Hospital (Kaser El Aini). After a written consent from parents, the same preterm infant pain response was continuously monitored 30 s before procedure and up to 6 min during the procedure over 2 days (one for venipuncture and one for heel lance). Results The total mean premature infant pain profile score significantly increased during venipuncture than heel lance. Behavioral state was significantly more unstable during vein puncture than heel lance. Venipuncture procedure significantly increased heart rate and decreased oxygen saturation more than heel lance. Conclusion Preterm infants perceive pain as demonstrated by premature infant pain profile scale and vein puncture is the more painful procedure than heel lancing for blood sampling in preterm infants. Recommendations Premature infant pain profile scale should be included in the routine assessment for preterm infants.
Dermoscopic differentiation of pustular psoriasis and tinea incognito

Introduction: Dermoscopy is a rapid diagnostic method in many inflammatory dermatoses which are diagnosed accurately by dermoscopy. Clinically, pustular psoriasis (PP) and tinea incognito (TI) look similar, and sometimes, TI is an invader into PP. Hence, it is important to differentiate each to manage them properly. Thus, a tool to distinguish both TI and PP is necessary for the correct diagnosis and management. Dermoscopy of PP is well-documented but not in TI. Here, we describe the dermoscopic differentiation of TI from PP with histopathological correlation. Materials and Methods: This was a cross-sectional study. Cases of PP and TI were included. DermLite 3 was employed. Potassium hydroxide (10%) mount and histopathological examination were done to confirm the diagnosis. Statistical analysis was done using “z” test. Results: A total of 20 TI and ten PP patients were in the study. Micropustules and scales were seen in all (100%) patients of PP and TI. Brown and black globules and hair changes were seen only in TI (100%), not in PP (0.0%). Red dots were observed in all PP patients (100%), not in TI (0.0%). Erythematous background in PP (100%) and in TI (70%) was statistically significant with P < 0.001. Conclusion: Dermoscopy is an in vivo tool to visualize the deeper structures of the skin. It demonstrates characteristic and different patterns in PP and TI as well, thus aiding in the differentiation of both the conditions. It would help treating physician to manage correctly and avoid unnecessary delay in the accurate diagnosis and treatment.
Impacts of Occupational Cognitive Failure and Subjective Workload on Patient Safety Incidents among Intensive Care Units Nurses

Background: Life-saving treatments and high-quality care techniques increase the opportunity for patient safety incidents in Intensive care unit. Aims: This descriptive correlation study aimed to determine the impacts of occupational cognitive failure and subjective workload on patient safety incidents among intensive care units nurses. Methods and Material: One hundred seventy-six nurses working in intensive care units were included using census sampling. The data collection tools consisted of demographic and occupational data, standard questionnaires of subjective workload (NASA-TLX) and occupational cognitive failure (OCFQ), and a question about frequency of patient safety incidents. Data analysis was performed using Mann–Whitney and Kruskal–Wallis, Spearman rank correlation coefficient, and logistic regression tests. Results: Occupational cognitive failure (OR = 1.043), subjective workload in dimension of “performance” (OR = 0.982), age (OR = 0.947), and gender (OR = 3.726) were important predictive variables of patient safety incidents. Conclusions: Nursing mangers and policymakers can consider the factors identified for staffing nurses and development of patient safety programs.
Identification, Classification, and Prioritization of Effective Factors in Producing Thermal Strain in Men at Workplaces using Fuzzy AHP Technique

Background: Various factors can affect thermal strain at workplaces. To prevent heat illnesses due to the heat strain, one must identify and prioritize these factors. Therefore, the present study was aimed to determine the relative importance of the effective factors in producing thermal strain in men at workplaces using fuzzy AHP technique. Materials and Methods: This qualitative practical study was performed in 2019. Effective factors in producing heat strain were identified by a literature review. Then, an expert panel reviewed the identified factors and omitted some of them. Further, the balance theory of job design was applied to classify the heat strain factors. Later, these factors were categorized into six groups, including environmental, personal, job, clothing, administrative, and lifestyle elements. In the end, the fuzzy analytical hierarchy technique was used for prioritizing the elements and factors involved in each of them. Results: Based on the results, the environmental element had the highest relative weight and priority (0.178). Other priorities were assigned to the job element (0.171), clothing element (0.171), personal element (0.169), administrative element (0.169), and lifestyle element (0.142), respectively. Conclusion: In general, the results showed that environmental factors are the most effective ones in producing heat strain. The results of the present study can be helpful in controlling the thermal strain.

The percentage viability of the cell line was carried out by using Trypan blue dye exclusion method. The cytotoxicity of Solanum Nigrum on HeLa cell was evaluated by the SRB assay and MTT assay. Solanum Nigrum methanolic extract has significant cytotoxicity effect on HeLa Cell Line in concentration range between 10 mg/ml to 0.0196 mg/ml by using SRB assay and study also showed that inhibitory action on HeLa cell line in concentration range between 10 mg/ml to 0.0196 mg/ml by using MTT assay. IC50 value and R 2 value of Solanum Nigrum on HeLa cell and Vero cell were 847.8 and 0.8724, 9088 and 0.1017 respectively by SRB assay. IC50 value and R 2 value of Solanum Nigrum on HeLa cell was 265.0 and 0.9496 respectively by MTT assay. IC50 value of Solanum Nigrum on Vero cell was 6.862 by MTT assay. R 2 value of Solanum Nigrum was not found by MTT assay. From the performed assay, methanolic extract of these drug shows greater activity on HeLa cell line and little activity on Vero cell line and that mean Solanum Nigrum can be used as anticancer
Pathology of Uddanam Endemic Nephropathy

In the last decade, pockets of endemic nephropathy have been recognized worldwide, in regions of Central America, Sri Lanka, and India. In India, the nephropathy has been recognized in the Uddanam area of north Andhra Pradesh and has been termed the Uddanam endemic nephropathy (UEN). The disease is distinctive in that besides the geographic distribution, it affects rural populations engaged in farm labor and agriculture, often silent in the initial phase with most patients presenting with advanced renal failure. The renal biopsy findings in all geographic areas including UEN have been one of a chronic tubulointerstitial nephritis with varying degrees of tubular injury, interstitial inflammation, tubular atrophy, and interstitial fibrosis with nonspecific glomerular obsolescence and lack of immune deposits. More recently, the demonstration of dysmorphic lysosomes in renal biopsies has favored a toxic etiology. There are thus many gaps in the understanding of this serious disease prevalent among poorer populations.
Musculoskeletal Disorders of Garo Women Workers Engaged in Tea-Plucking Activity: An Ergonomic Analysis

Background: The tea-plucking activity in Garo Hills, Meghalaya, India is performed in a traditional way making the majority of women workers, especially those who have spent more years in tea-plucking activity prone to musculoskeletal disorders. Materials and Methods: The present study was conducted on a sample of 40 women workers who had the highest field experience in tea leaf plucking. Pain as a musculoskeletal disorder was recorded using a 5-point scale ranging from very mild pain (1) to very severe discomfort (5) to quantify the stress on muscles used in work. The coefficient of correlation was used to explore the relationship between age, years of involvement, BMI of women, and their musculoskeletal problem. The analysis of discomfort in upper extremity was done by using a rapid upper limb assessment (RULA) technique. Analysis of discomfort in entire body parts was carried out using a rapid entire body assessment (REBA) technique. Results and Discussion: During tea plucking, women workers reported severe discomfort in the head (4.5), neck (4.3), both fingers (4.2), upper and lower back (4.3 and 4.4), and feet (4.3). The RULA grand score was observed seven indicating the need for immediate investigation and changes. REBA result was 11 for entire body parts leading to conclude that workers were working under high physical strain. Conclusion: Workers with severe musculoskeletal disorders can face permanent disability that prevents them from returning to their jobs or handling simple everyday tasks. Therefore, some rest periods, ergonomic intervention, and personal protective equipment are needed to minimize the discomfort of women workers in the tea-plucking activity.

A comparative evaluation of cyclic fatigue resistance of FlexiCON (Edge Endo) files in rotary versus reciprocating motion at various curvatures – An in vitro study

Aim: The aim of the study to compare the cyclic fatigue resistance of FlexiCON (Edge Endo) files in rotary versus reciprocating motion in coronal, middle, and apical curvature of the simulated artificial canal. Materials and Methods: A total number of 36 new files, 25 mm length of ISO size 25 at the tip and a taper of 0.06, were used for the study and divided into two groups of 18 files each. Group I: FlexiCON X3, was used in a rotary motion and Group II: FlexiCON X1was used in a reciprocating motion. Cyclic fatigue testing was conducted in a custom-made device that allowed for a reproducible simulation of a curved canal. The canal system, which comprised two adjustable stainless steel blocks, had a 60° angle of curvature and 3 mm width. The groups were further divided into three subgroups with six files in each, representing apical curvature (Group Ia/IIa), middle curvature (Group Ib/IIb), and Coronal curvature (Group Ic/IIc). Using X-Smart plus motor, files were used in rotary and reciprocating mode and the number of cycles to failure was recorded. Statistical Analysis: Data were analyzed using ANOVA and Post hoc followed by Dunnett's test and unpaired t-test using Statistical Package for the Social Sciences 16 version. Results: FlexiCON X1 reciprocating files showed the maximum cyclic fatigue resistance at coronal curvature (1936.50 ± 1.09) followed by middle (1514.50 ± 1.07) and apical curvature (1487.50 ± 6.75), while FlexiCON X3 rotary files showed the maximum cyclic fatigue at the middle curvature (1106.00 ± 4.21), followed by coronal (920.00 ± 1.16) and apical curvature (757.00 ± 5.34). The statistical analysis revealed a statistically significant difference (P = 0.001) between the two groups. Conclusion: FlexiCON X1 reciprocating files showed better cyclic fatigue resistance at coronal, middle, and apical curvature compared to FlexiCON X3 rotary files.
Scanning electron microscopy evaluation of chitosan and carboxymethyl chitosan as retrograde smear layer removing agents

Background: The smear layer acts as a physical barrier against penetration of root canal medicaments and sealers, thus compromising the seal leading to microleakage. Objectives: This study was conducted to evaluate the efficacy of 17% ethylenediaminetetraacetic acid (EDTA), 0.2% chitosan solution, and 0.2% carboxymethyl chitosan (CMC) used as smear layer removing agents in retrograde root canal preparation using scanning electron microscopy (SEM). Materials and Methodology: Eighty single-rooted teeth extracted for periodontal reasons were collected for the study. Root canals were prepared and obturated with gutta-percha coated with AH plus resin sealer. Apical 3 mm of each root resected and Class I retrograde preparation carried out using ultrasonic handpiece and ultrasonic retro tips to a depth of 3 mm along the root long axis. In Group 1 (control), normal saline solution alone was used for smear layer removal. In Group II, 17% EDTA, Group III and IV were treated with 5 ml of 0.2% chitosan and 0.2% carboxyl methyl chitosan, respectively, for 3 min. Blinded evaluation of specimens using SEM was performed independently by two operators who registered the amount of the smear layer present on the surface of the canal walls based on the score described by Hülsmann et al. Results: Group I (saline) was least efficient in the removal of the smear layer. Group II (17% EDTA), Group III (0.2% Chitosan), and Group IV (0.2% CMC) efficiently removed the smear layer from the retrograde cavity with mean scores 1.35, 1.60, and 1.35, respectively. Statistically, no significant difference found in Group II (17% EDTA), Group III (0.2% Chitosan), and Group IV (0.2% CMC). Conclusions: About 0.2% CMC and 0.2% chitosan can be better alternatives to 17% EDTA for smear layer removal due to their biological advantages.
Total column water vapor retrieval for Global Ozone Monitoring Experience-2 (GOME-2) visible blue observations

Abstract. We present a new total column water vapor (TCWV) retrieval algorithm in the visible blue spectral band for the Global Ozone Monitoring Experience 2 (GOME-2) instruments on board the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) Metop satellites. The blue band algorithm allows the retrieval of water vapor from sensors which do not cover longer wavelengths, such as the Ozone Monitoring Instrument (OMI) and the Copernicus atmospheric composition missions Sentinel-5 Precursor (S5P), Sentinel-4 (S4) and Sentinel-5 (S5). The blue band algorithm uses the differential optical absorption spectroscopic (DOAS) technique to retrieve water vapor slant columns. The measured water vapor slant columns are converted to vertical columns using air mass factors (AMFs). The new algorithm has an iterative optimization module to dynamically find the optimal a priori water vapor profile. This makes it better suited for climate studies than usual satellite retrievals with static a priori or vertical profile information from the chemistry transport model (CTM). The dynamic a priori algorithm makes use of the fact that the vertical distribution of water vapor is strongly correlated to the total column. The new algorithm is applied to GOME-2A and GOME-2B observations to retrieve TCWV. The data set is validated by comparing it to the operational product retrieved in the red spectral band, sun photometer and radiosonde measurements. Water vapor columns retrieved in the blue band are in good agreement with the other data sets, indicating that the new algorithm derives precise results and can be used for the current and forthcoming Copernicus Sentinel missions S4 and S5.
