Comparison of clinical efficacy of bupivacaine-fentanyl with ropivacaine-fentanyl in patients undergoing abdominal and pelvic procedures

Background: The pain after major abdominal surgeries, if treated inadequately, may lead to increased postoperative morbidity and delayed recovery. Epidural analgesia is one of the most effective regimens for postoperative analgesia. The present study was undertaken to evaluate and compare the clinical efficacy of bupivacaine-fentanyl with ropivacaine-fentanyl in patients undergoing abdominal and pelvic procedures. Method: Total 80 adult patients of age between 18 to 55 years were enrolled and divided into two groups of 40 patients in each. Group BF received 0.5% bupivacaine for epidural block with Fentanyl 25 micro gm and Group RF received 0.75% ropivacaine for epidural block with Fentanyl 25 micro gm. Results: Two groups were statistically similar for demographic profile and duration of surgery, (p>0.05). In both the groups, majority of patients were undergoing abdominal surgery (BF-55% vs. RF60%) compared to pelvic surgery (BF-45% vs. RF-40%), (p = 0.821). There was no significant difference between two groups with respect to haemodynamic parameters (HR, SBP, DBP, MAP and SpO2) and respiratory rate at different perioperative intervals. Higher time to request first rescue analgesic in patients received ropivacaine-fentanyl (RF group), which was statistically significant. Also the duration of analgesia was longer in RF group (176.73 ± 11.13) than BF group (170.98 ± 8.60), (p = 0.012). Incidence of nausea, vomiting, hypotension and bradycardia were comparable between two groups. Conclusion: The epidural infusion of 20 ml of 0.75% ropivacaine with fentanyl 25μg provides adequate anesthesia for lower abdominal and pelvic surgeries, also it provides longer intraoperative and postoperative analgesia with hemodynamic stability compared with bupivacaine 0.5% with fentanyl.

Towards Analysis and Optimization during Machining Hardened Steel AISI 4140 with Self-Propelled Rotary Tools

It is necessary to improve the machinability of difficult-to-cut materials such as hardened steel, nickel-based alloys, and titanium alloys as these materials offer superior properties such as chemical stability, corrosion resistance, and high strength to weight ratio, making them indispensable for many applications. Machining with self-propelled rotary tools (SPRT) is considered as one of the promising techniques used to provide proper tool life even under dry conditions. In this work, an attempt has been performed to analyze, model, and optimize the machining process of AISI 4140 hardened steel using self-propelled rotary tools. Experimental analysis has been offered to (a) compare the fixed and rotary tools performance, and (b) study the effect of the inclination angle on the surface quality and tool wear. Moreover, the current study implemented some artificial intelligence-based approaches (i.e., genetic programming and NSGA-II) to model and optimize the machining process of AISI 4140 hardened steel with self-propelled rotary tools. The feed rate, cutting velocity, and inclination angle are selected to be the design variables, while the tool wear, surface roughness, and material removal rate (MRR) are the studied outputs. Moreover, different weights have been assigned for the three studied outputs to offer different optimized solutions based on the designer interest (equal-weighted, finishing, and productivity scenarios). It should be stated that the findings of the current work offer valuable recommendations to select the optimized cutting conditions when machining hardened steel AISI 4140.
Chemical Compositions and Antioxidant Potentials of the Aqueous-Methanol Extract and Essential Oil of Gongronema latifolium Leaves

Protection of cells against damage by reactive oxygen species is a way of preventing disease conditions and food-derived anti-oxidants, which can prevent such damages, are of great interest. Polyphenols and essential oil of medicinal plants are antioxidants and this turns our attention to Gongronema latifolium extracted and their mechanisms of antioxidant action were investigated. Aldehydes, octanal and decanal as well as monoterpene class of compounds were detected from the essential oil of G. latifolium . The essential oil and aqueous-methanol extracts showed strong antioxidant activities by inhibition of lipid peroxidation, chelation of Iron (II) ions, scavenging of both Hydroxyl and α, α-diphenyl-β-picryl-hydrazyl radicals. The study demonstrates the strong antioxidant potentials of the essential oil and aqueous-methanol extracts which explains the potency assigned to it in traditional medicine and highlights its potential usefulness in preventing lipid peroxidation in food systems.
A Comprehensive Analysis of Crowdsourcing for Subjective Evaluation of Tone Mapping Operators

Tone mapping operators (TMO) are pivotal in rendering High Dynamic Range (HDR) content on limited dynamic range media. Analysing the quality of tone mapped images depends on several objective factors and a combination of several subjective factors like aesthetics, fidelity etc. Objective Image quality assessment (IQA) metrics are often used to evaluate TMO quality but they do not always reflect the ground truth. A robust alternative to objective IQA metrics is subjective quality assessment. Although, subjective experiments provide accurate results, they can be time-consuming and expensive to conduct. Over the last decade, crowdsourcing experiments have become more popular for collecting large amount of data within a shorter period of time for a lesser cost. Although they provide more data requiring less resources, lack of controlled environment for the experiment results in noisy data. In this work1, we propose a comprehensive analysis of crowdsourcing experiments with two different groups of participants. Our contributions include a comparative study and a collection of methods to detect unreliable participants in crowdsourcing experiments in a TMO quality evaluation scenario. These methods can be utilized by the scientific community to increase the reliability of the gathered data.

Molecular origin of the anisotropic dye orientation in emissive layers of organic light emitting diodes

Molecular orientation anisotropy of the emitter molecules used in organic light emitting diodes (OLEDs) can give rise to an enhanced light-outcoupling efficiency, when their transition dipole moments are oriented preferentially parallel to the substrate, and to a modified internal quantum efficiency, when their static dipole moments give rise to a locally modified internal electric field. Here, the orientation anisotropy of state-of-the-art phosphorescent dye molecules is investigated using a simulation approach which mimics the physical vapor deposition process of amorphous thin films. The simulations reveal for all studied systems significant orientation anisotropy. Various types are found, including a preference of the static dipole moments to a certain direction or axis. However, only few systems show an improved outcoupling efficiency. The outcoupling efficiency predicted by the simulations agrees with experimentally reported values. The simulations reveal in some cases a significant effect of the ho.
Synthesis and crystal chemistry of Fe 3+ -bearing (Mg,Fe 3+ )(Si,Fe 3+ )O3 perovskite

We have synthesized magnesium-iron silicate perovskites with the general formula Mg1–xFe 3+ x+ySi1–y O3, in which the iron cation is exclusively trivalent. To investigate the crystal chemistry of Fe 3+ -bearing perovskite, six samples (both with and without Al) were analyzed using scanning electron microscopy, electron microprobe, X-ray diffraction, and Mossbauer spectroscopy. Results indicate that Fe 3+ substitutes significantly into both the octahedral and dodecahedral sites in the orthorhombic perovskite structure, but prefers the octahedral site at Fe 3+ concentrations between 0.04 and 0.05 Fe per formula unit, and the dodecahedral site at higher Fe 3+ concentrations. We propose a model in which Fe 3+ in the A/B site (in excess of that produced by charge coupled substitution) is accommodated by Mg/O vacancies. Hyperfine parameters refined from the Mossbauer spectra also indicate that a portion of dodecahedral sites undergo significant structural distortion. The presence of Fe 3+ in the perovskite
Comparison of the apoptotic effects of bortezomib using 2D and 3D co-culture models of THP-1 derived macrophage and A549 lung cancer

: We investigated the fundamental function of the lung cancer tumour microenvironment. Proteasome inhibition has emerged as a clinically successful anti-cancer therapeutic strategy, with the antineoplastic medication bortezomib showing high efficacy against multiple cancers. Tumour-associated macrophages (TAMs), which migrate to tumour stroma, are known to promote cell proliferation, apoptosis, and metastasis within the lung cancer microenvironment. However, the specific interaction of macrophages, lung cancer cells, and bortezomib are still unclear. Most in vitro cell cultures are traditionally grown in a two-dimensional (2D) culture system, although 3D cultures have demonstrated greater success in terms of drug response, gene expression and viability. Therefore, to elucidate the role of macrophages, we aimed to establish a co-culture model in both 2D and 3D cultures using A549 human lung cancer cells and THP-1 derived macrophages. Apoptotic effects were analysed using the Annexin V-PI method. Since NF-kB and TNF-α play important roles in the anti-proliferation and apoptosis pathways, the levels of NF-kB and TNF-α mRNA expression were measured. As a result, bortezomib significantly increased cell apoptosis in cells co-cultured with M0 macrophages. IL-1β cytokine levels also increased, and NF-kB mRNA expression levels decreased. Understanding the mechanisms that modulate the tumour microenvironment may facilitate the development of novel anticancer therapies. The utilisation of TAMs may improve the successful treatment of lung cancer and warrants further study.
Effectiveness of Cerebroplacental Ratio Estimation Early in Labor as A predictor of Adverse Perinatal Outcomes in Full-term Low-risk Pregnancy

Objective of the Study: To test the efficacy of the cerebroplacental ratio [CPR] in the prediction of early labor fetal distress and adverse neonatal outcomes in full-term [FT] low risk pregnancy. Patients and Methods:One hundred fifty pregnant women met the inclusion and exclusion criteria were subjected for the estimation of umbilical artery [UA] and middle cerebral artery [MCA] pulsatility indices [PI]]. CPR is calculated by dividing MCAPI by UAPI. All of these measures have been converted to multiple medians [MOMs]. The findings of CPR MOM were Correlated with the following; traces of cardiotocography; cesarean section [CS] for fetal distress; 5 min APGAR scoring; cord PH; and NICU admission. The ROC curve was used to test CPRMOM's predictive performance of adverse perinatal outcomes. Results:Out of 150 patients, 18 [12%] showed abnormal CPR MOM There was negative significant correlation between CPRMOM and both of emergency CS, [r=-0.293, p <0.001] and NICU admission [r=-0.302, p <0.001. ROC curve showed that CPRMoM is good negative predictor, in both CS due to fetal distress, and NICU admission at cut off values,≤0.97 and ≤0.84 with sensitivity, 72.7 % and 75.0 %, specificity, 91.4 % and 92.3 % with AUCs, 0.778 and 0.827, P = 0.005, and < 0.001 respectively. Conclusion: Reduced CPRMOM < 1 considers a good predictor for both of CS due to fetal distress and NICU admission; however normal CPR doesn’t rule them out. Reduced CPR MOM is a poor predictor for each of initial non reassuring CTG, APGAR score at 5 min and lower umbilical PH. Nevertheless, normal CPRMOM considers as good predictor for normal fetuses.
The Technical Efficiency of Small-scale Tea Plantation in Sri Lanka

The tea smallholding sector is the leader in national tea production in Sri Lanka. However, it is believed that increasing profit is very difficult without increasing costly inputs, considering the high cost of production. This paper investigates the technical efficiency of smallholder tea farmers (STFs) in Sri Lanka by employing stochastic production frontier using a sample of 120 STFs. The results showed that the average technical efficiency of selected STFs is 78.44 per cent. This indicates that output can be further increased by 21.56 per cent without increasing the level of input. Gender and access to quality extension services were identified as the variables that have the greatest impact on technical efficiency. The results further showed the labour is the most important factor for tea production.
Identification of Oxidation Intermediates in Humic Acid Oxidation

ABSTRACT The effects of using ultraviolet irradiation (UV), ozone (O3) and the combined O3-UV advanced oxidation process (AOP) on humic acid (HA), which is regarded as the main disinfection by-products (DBPs) precursor, have been evaluated and compared. In particular, aromatic acids, short-chain aldehydes and carboxylic acids were measured. The purpose of this study was to determine the different classes and yields of oxidation intermediates, compare O3, UV and O3-UV for HA removal, as well as investigate the effects of O3, irradiation time, UV intensity on the mineralization of HA. Based on that, the knowledge gap of DBPs generation was made up. The results showed that by UV irradiation and O3 oxidation, HA broke down into smaller molecules that were more hydrophilic, namely formaldehyde, acetaldehyde, propaldehyde, butyraldehyde, glyoxal, methyl-glyoxal, formic, acetic, fumaric, benzoic, phthalic, protocatechuic and 3-hydroxybenzoic acids. Meanwhile, unsaturated conjugated double bonds in the structure of HA were destroyed, which lead to UV254 a slight decrease. Due to the synergistic effect of O3-UV, DOC and UV254 significantly decreased and remained stable after the reaction of 10 min, indicating that O3-UV system had stronger potential of mineralization and lower nonselectivity. Besides, the kinds and concentration levels of the intermediates were obviously reduced with light intensity increasing. Hydroxyl radical (.OH) could mineralize some organics that could not be mineralized by O3.
Assessment of Gypsum And Limestone Rocks from Fat’ha Formation (m. Miocene) for Making Wallboard in The Makhmur Area – Northern Iraq

Five samples of gypsum and one sample of limestone were collected from an outcrop in Qara Chugh Anticline. The samples of gypsum were analyzed chemically before and after calcination. The purity of the samples of gypsum and limestone was calculated and the (H2O + ) content of the calcined samples of gypsum was determined. The physical and mechanical properties of plaster of Paris produced from calcining the samples of gypsum were tested according to the Iraqi and American Standards. A wallboard sample was made using basic materials according to the American Standard. The chemical analyses of the samples of gypsum and plaster of Paris conform to the Iraqi and American Standards. The Fat'ha Formation rocks in the Makhmur area are suitable for making wallboard. The optimum conditions for calcining the studied gypsum rocks to produce plaster of Paris conforming to the standard specifications and suitable for the manufacture of wallboard are 130 °C for 1 hour.
Congenital Malformation among Children with Cerebral Palsy, And Gender Differences in El- ALBYDA Hospital in LIBYA

Cerebral palsy (CP) is a major neurodevelopmental disorder, presently estimated to affect approximately 1 in 500 children. As a clinical diagnosis, the etiology of the syndrome varies and is often unknown. The objective of this study is to determine the pattern and the contributing factors of CP among Libyans children. This was a descriptive hospital-based study conducted over a period of six years in ALBYDA Central Hospital – LIBYA. One hundred and eight patients of CP were enrolled, of whom 70 (65%) were males and 38 (35%) were females. Spastic quadriplegic CP was the most common type and epilepsy was the most problem associated with CP. Birth asphyxia, prematurity neonatal meningitis, kernicterus and brain malformation were the main contributing factors.
Rupture analysis of the 2020 Petrinja earthquake based on seismological observations

<p>Here, I use seismological observations (~70 broadband stations at distances between 100 and 400 km from the source) to characterize the rupture properties of the Petrinja mainshock (Mw 6.4). First, I perform a spectral analysis of the P-waves to compute the corner frequency. In order to remove the wave propagation effects and isolate the source properties, I use the largest foreshocks and aftershocks (Mw>4) as empirical Green&#8217;s functions (EGFs). Assuming a Brune&#8217;s source model, the obtained stress drop is ~20 MPa. This rather large value is in agreement with the short rupture length of ~8 km inferred by InSAR data (Ganas et al. 2021). In addition, the weak azimuthal variations of the corner frequencies indicates a bilateral rupture, that is a rupture nucleating close to the fault center. Second, I compute the apparent source time functions (i.e. the source time functions &#8220;seen&#8221; from any station) using an EGF deconvolution approach. The results indicate an average rupture duration of 5-6 s with weak azimuthal variation of the apparent rupture duration, in agreement with the spectral analysis. Finally, I perform a Bayesian inversion of the apparent source function, in order to obtain a kinematic model of the rupture propagation (slip distribution, rupture velocity). The preliminary results reveal a slow velocity of the rupture propagation. Such a slow rupture velocity associated with a large stress drop has been observed on other faults with slow slip rates (e.g. Causse et al. 2017). This work provides insight on the rupture process of this major event on a poorly documented fault. I am fully open for collaborations to further develop and enrich this study. </p><p><br><strong>References</strong><br>Causse, M. , G. Cultrera, L. Moreau, A. Herrero, E. Schiapappietra and F.

The Effect of Perceived Organizational Support on Employee Engagement During the COVID-19 Pandemic: An Empirical Study in Vietnam

Employee engagement at workplace is very important for organizations, however, the motivators to keep the employees engaged vary. It has been normally observed that personality and job satisfaction has been the main causes which can motivate employees. However, the COVID-19 pandemic has brought a lot of changes, and the main aim of this study is to analyze the determinants of employee engagement during Covid-19 pandemic with the mediating role of Perceived organizational support and Perceived family support. Through a survey instrument, data was collected from 216 employees working at corporate offices in Hanoi, Vietnam. Partial least squares structural equation modeling (PLS-SEM) was applied to test the study hypotheses using Smart-PLS. The study underlined the significant positive effect of Perceived Organizational support and Perceived Family Support on Employee Engagement. Moreover, Employee engagement also measures the indirect effects from factors such as colleague support, supervisor support, organizational support, spousal support and family members supports on Employee Engagement. Some discussions are given based on the findings of this research in comparison with findings of prior studies in different contexts. This research is evidenced in the emerging countries and Vietnam as the case study.
