Evaluation of Erythrocyte Sedimentation Rate, C Reactive Protein and Ante-Streptolysin O Titer Regarding Tonsillectomy Indication and their Postoperative Changes

Objective: To evaluate the serum erythrocyte sedimentation rate, C reactive protein and ante-streptolysin O titer as indicators for tonsillectomy with assessment of their postoperative changes.Methods: Our prospective comparative study was carried out on 150 patients divided into two groups. Group I included 75 patients clinically diagnosed as chronic tonsillitis by symptoms and signs and group II included 75 patients with previous tonsillectomy as a control group. Both groups were compared regarding the levels of the three laboratory markers. Also, the preoperative values of these markers were compared with postoperative values at 1, 3 and 6 months.Results: The values of the three markers in group I were higher than values in group II but statistically insignificant (p = 0.13, 0.11 and 0.78 respectively). There was a highly significant decrease in postoperative results of erythrocyte sedimentation rate, C reactive protein in group I at 1, 3 and 6 months after tonsillectomy (p value < 0.0001for all). There was a significant decrease in postoperative results of ante-streptolysin O titer in group I at 1, 3 and 6 months after tonsillectomy (p= 0.008, 0.019, 0.001 respectively). Conclusion: Erythrocyte Sedimentation Rate, C Reactive Protein and Ante-Streptolysin O Titer should not be considered as indicators for tonsillectomy in chronic tonsillitis patients by having a non-significant difference when compared with post tonsillectomy patients. Being inflammatory markers, the values of these markers showed a significant decrease after tonsillectomy due to removal of the septic focus of chronic tonsillitis.
Measurements of Hydrodynamic Parameters for Nematic 5CB

Abstract A nematic liquid crystal, pentyl-cyano-biphenyl (5CB) is studied in two different flow situations: Poiseuille flow and torsional shear flow, in both cases with and without the simultaneous application of an electric field. The Poiseuille flow set-up gives an accurate determination of the Miesowicz viscosity ηc and a less precise estimation of ηb. With ηc known it is possible to separately determine the elastic constants K 11 and K 33 and the viscous coefficients α2, α3, and thereby γ1, γ2 from the torsional shear flow experiment. Using the data we have also been able to calculate the actual director profile in the liquid crystal as a function of applied shear and electric field. Curves are given of K 11, K 33, K 11/K 33, α2, α3, γ1, γ2, γ1/γ2, ηb and ηc for 5CB as a function of temperature through the whole nematic range from 22.0 °C to 35.1 °C. After the completion of our manuscript we have noticed the recent article by J. Wahl, Z. Natur-forsch. 34a, 818 (1979). Wahl discusses shear flow in the .
Improved polytope volume calculations based on Hamiltonian Monte Carlo with boundary reflections and sweet arithmetics

Computing the volume of a high dimensional polytope is a fundamental problem in geometry, also connected to the calculation of densities of states in statistical physics, and a central building block of such algorithms is the method used to sample a target probability distribution. This paper studies Hamiltonian Monte Carlo (HMC) with reflections on the boundary of a domain, providing an enhanced alternative to Hit-and-run (HAR) to sample a target distribution restricted to the polytope. We make three contributions. First, we provide a convergence bound, paving the way to more precise mixing time analysis. Second, we present a robust implementation based on multi-precision arithmetic-a mandatory ingredient to guarantee exact predicates and robust constructions. We however allow controlled failures to happen, introducing the Sweeten Exact Geometric Computing (SEGC) paradigm. Third, we use our HMC random walk to perform H-polytope volume calculations, using it as an alternative to HAR within the volume algorithm by Cousins and Vempala. The tests, conducted up to dimension 50, show that the HMC random walk outperforms HAR.
Chemical and Leaching Behavior of Construction and Demolition Wastes and Recycled Aggregates

Construction and demolition wastes are widely recognized as the main waste stream in the EU, and their recycling and recovery is an important issue in sustainable building industry development. The composition of construction and demolition wastes is highly heterogeneous and is influenced by several factors, including the raw materials and construction products used. The environmental performance of these materials are therefore considerably variable and, in some cases, do not comply with the regulatory limits established to ensure the protection of the natural environment. In this context, this paper presents a data analysis on the environmental behavior of construction and demolition wastes and recycled aggregates in terms of both chemical composition and the release of contaminants according to a leaching test. Subsequently, the most critical parameters for recovery were identified and statistically evaluated. The leaching results showed that SO4, Cu, and COD are critical compounds for both CDWs and RAs.
Profiling the unemployed from selected communities in South Africa based on their experiences, commitment to employment, and job search behaviour

Unemployment has negative consequences for individuals’ psychological well-being. Consequently, interventions should be designed and implemented to alleviate the psychological burden of unemployment. The design of these interventions should, however, be approached with care, as ‘the unemployed’ may not be a homogeneous group. The aim of the study was to determine whether the four already identified (the optimists, the desperate, the discouraged, and the adapted) South African unemployment profiles could be replicated in other unemployed communities in South Africa. The study also aimed to examine the associations between these profiles and negative emotions and basic psychological need frustration. To establish the replicability of the types, a multiphased sampling design was followed to recruit 867 unemployed people residing in Boipatong and Orange Farm in the Gauteng Province in South Africa. Through latent profile analysis, the study replicated the four profiles: the optimists, the desperate, the discouraged, and the adapted. The profiles were differentially associated with negative emotions and psychological need frustration, further attesting to the validity of the profiles. The results of the study can be applied towards creating tailored interventions for the different types of unemployed people from South African communities to enhance the efficacy of these interventions.
A co-constructed picture of learning in play by teachers and parents

In discussions about how to implement learning through/in/at play, there is still not a commonly agreed view. This qualitative study investigated Chinese teachers’ and parents’ perspectives on learning in play to attain a co-constructed picture of learning in play through real classroom practices and perceptions using the Mosaic approach. Fourteen teachers and six parents took part in this study. Among the participants, six kindergarten teachers were interviewed to obtain their perspectives on learning in play. They assisted the researchers in the selection of exemplary play episodes, which were filmed in their own classrooms. Four three-minute videos containing the largest amount of learning elements based on the teachers’ views were selected for further in-depth focus group discussions. The selected multivocal video-cued interview clips were shown to eight other teachers and six parents in focus groups to elicit their perspectives on learning in play. The co-constructed picture of learning in play that emerged included discipline in the classroom, more difficult and complicated learning matters, more freedom to play, and teachers’ intervention to facilitate children’s learning in play. The findings revealed different social representations of learning in play in the Hong Kong context, the contributions of which are important and useful for professional education practices and curricular policy currently undergoing reform.
A two-dimensional numerical study of film boiling over an elliptical cylinder in the mixed regime under aiding and orthogonal saturated liquid flow configurations

Abstract Saturated film boiling over an elliptical heater is investigated in the mixed regime considering both aiding and orthogonal liquid flow configurations relative to gravity. A computational framework developed for phase change problems on unstructured grids based on a coupled level set and volume of fluid interface capturing method is used to characterize interface evolution and vapour wake dynamics alongside quantifying heat transfer at low values of the Froude number (Fr). The influence of hydrodynamic and thermal conditions along with cross-flow direction for a fixed heater geometry manifests in the form of varied wake profiles with the quasi-steady nature of film boiling lost as Fr increases. Additionally, while the heater aspect ratio affects the rate of vapour infusion into the wake, the heater orientation significantly affects the film boiling behaviour. With horizontal cross-flow, higher angles of incidence entail a lower influence of flow inertia while augmenting buoyancy-driven vapour removal leading to enhanced heat transfer compared to aiding flow under certain cases, and adding a further dimension to the interplay between buoyancy and inertia. Similarly an anomalous impairment of heat transfer with an increase in cross-flow velocity arises from a competing influence of buoyancy and drag as an artefact of heater and cross-flow configurations. The mutual coupling of liquid and vapour wakes is also discussed in detail under such conditions. Finally, a shape factor $(\psi )$ is proposed to comprehensively predict the heat transfer in conjunction with correlations for a circular heater, and determined based on the effect of the elliptical geometry in the mixed regime.
Multi-conductor coaxial cavity resonators for miniaturization of UHF bandpass filters

In this paper, we present the compact bandpass cavity filters for UHF range. We investigate the properties of coaxial resonators with various numbers of tubular posts from one to four. We show that the resonant frequency can be four times smaller for the four-post resonator in comparison with the single post resonator with the same cavity dimensions. We synthesized and manufactured fifth-order bandpass cavity filter on four-post coaxial resonators for the 690–806 MHz frequency range with 20-dB return loss. The filter dimensions were 30 mm × 44 mm × 127 mm. We also synthesized and manufactured the fifth-order bandpass cavity filter on four-post coaxial resonators with inductive and capacitive cross-coupling between first and fifth resonators to provide transmission zeros in amplitude–frequency characteristic in lower- and upper-frequency band, respectively. Comparison with the standard double-post coaxial cavity filters demonstrates more than 30% volume reduction with similar transmission characteristics.
Urinary Tract infection, Drug Resistance Profile and Fetal Outcomes among Pregnant women in Selected Health Facilites of Addis Ababa, Ethiopia: A cross-sectional study design

Background: Urinary tract infection (UTI) is a commonly encountered health problem among pregnant women. Untreated UTI may result in fetal complications like preterm birth, low birth weight, intra uterine growth retardation and intrauterine fetal death.One of the major problems with bacterial pathogens is their ability to develop drug resistance. Determining drug susceptibility pattern of bacteria from urinary tract helps to identify effective drugs and minimize further adverse perinatal outcomes. The purpose of this study was to describe the magnitude and drug resistance profile of pregnant women and related fetal outcomes.Methods: A cross-sectional study was conducted from March to June 2019. Socio-demographic data of the study participants was collected by administering structured questionnaire after obtaining full consent of the participants. Clean catch mid-stream urine was collected from the study participants and the samples were transported to the laboratory with screw-capped container. Blood and MacConkey agar were used to cultivate bacteria from urine sample. Bacterial colonies were isolated and identified using standard biochemical properties. Antibacterial susceptibility test was done on Muller-Hinton agar using antibiotic discs. At the time of delivery, infant’s birth weight and gestational age was recorded on the log book as part of the daily work. Fetal outcome data were recorded from the log book and entered to EPI data management software then transferred to SPSS for analysis.Results: Out of 424 urine samples processed, 63 (14.9%) yielded significant bacteriuria. Fifty-nine out of 63 (93.7%) cases of UTIs were recorded among age group of 15-34 years. Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus were the three dominant bacterial isolates.Most of the gram negative bacterial isolates were resistant to ampicillin and ceftazidime (43.2% each) while gram positive was resistant for tetracycline (36.8%). The result of this study showed that UTI had statistical association with the occurrence of Intrauterine Fetal Death (IUFD) and Prerupture of Membrane (PROM) (P<.05). Conclusion: Adverse fetal outcomes are significantly linked with the presence of UTI during pregnancy. The condition can be managed if early diagnosis and treatments are made for the mother.
Coculture of white rot fungi enhance laccase activity and its dye decolorization capacity

Fungal cocultures can promote complex interactions that result in physiological and biochemical alterations that favor the synergic and more efficient action of extracellular enzymes such as laccase. Thus, coculture can be used as a strategy to increase enzymatic activity, dye degradation, and bioremediation of textile effluents. This study aimed to evaluate the coculture effect of Lentinus crinitus, Pleurotus ostreatus, Pycnoporus sanguineus, and Trametes polyzona on laccase activity, mycelial biomass production, and in vitro decolorization of azo, anthraquinone, and triphenylmethane dyes. The species were cultivated in liquid medium in monoculture and coculture in paired combinations for 15 days to determine the laccase activity and produced mycelial biomass. The enzymatic extracts of fungal cultivations were used in decolorization tests of reactive blue 220 (RB220), malachite green (MG), and remazol brilliant blue R (RBBR). Pleurotus-Trametes, Lentinus-Pleurotus, and Lentinus-Trametes cocultures increase laccase activity compared to respective monocultures. Lentinus-Pycnoporus, Lentinus-Trametes, Lentinus-Pleurotus, and PleurotusTrametes cocultures stimulate mycelial biomass production in relation to their respective monocultures. The enzymatic extracts of monocultures and cocultures promoted the decolorization of all dyes. RB220 dye presented fast decolorization. In 24 h, all extracts reached maximum decolorization and the greatest color reduction percentage was 90% for Pleurotus-Trametes coculture extract. Pleurotus-Trametes extract also increased the decolorization of MG and RBBR dyes when compared to their respective monocultures in 48 Research, Society and Development, v. 9, n. 11, e88191110643, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi. org/10.33448/rsd-v9i11.10643 3 h and 72 h, respectively. However, RBBR dye presented the greatest resistance to decolorization.
Empowering perovskite PbTiO3 nanoparticles with enhanced up-conversion luminescence and thermal sensitivity by introducing Er3+ dopant

Up-convertion (UC) perovskite Er3+-doped PbTiO3 (Er-PTO) nanoparticles with green and red emissions were synthesized via the hydrothermal method. The UC properties were manipulated by adjusting the concentration of Er3+ ions dopant. The green emission intensity was decreased as the doping concentration increased from 1% to 4% (mole fraction), whereas the red emission intensity was increased. The influences of Er3+ ions on the temperature-sensing performance were further investigated. The results demonstrated that Er-PTO nanoparticles with doping 1% Er3+ ions possessed a sensitivity of 3.1 × 10-3 K−1 at 475 K, presenting a high potential in optical heating devices.
Exploring deposition pattern characteristics of aerosols and bioaerosols by inertial impaction for the development of real-time silicon MEMS mass detection systems

Abstract The objective of this study was to analyze the deposition patterns of aerosolized bacteria, fungi, and fluorescent particles with a lab-made, multiple round nozzle, single-stage inertial impactor. The cutoff diameter (d50 ), experimental d50 , and Reynolds number of the impactor were 0.39 µm, 0.80 µm, and 2825, respectively. The impactor was elaborated based on a classical impactor design criterion. The deposition characteristics, namely the size, shape, and collection efficiency of aerosols, differed significantly for impaction surfaces like smooth silicon and nanostructured silicon (i.e., black silicon) and various sizes of particles. Our experiment results, based on the image analysis method, suggest that the impaction characteristics of aerosols are subject to a rebound and re-entrainment (i.e., bounce effect) phenomenon that is tuned by the size of the particles, regardless of their origin. This finding leads us to distinguish the collection of global (classical) and local efficiencies, based on where the particles are deposited on the impaction plate. The particles in the primary impaction zone, located underneath the nozzle to which a Micro-Electro-Mechanical System (MEMS) is aligned, are considered to evaluate the local collection efficiency. We estimated the local collection efficiency from the collection on a smooth silicon surface as 17.9 ± 1.8% for fluorescent particles with an aerodynamic diameter (dae ) of 0.92 µm and <1% for particles with dae of 2.07, 2.53, and 3.83 µm in size. The reduced number of particles in the primary impaction zone as their size increases is evidence of the bounce effect. This observation is also confirmed for the first time with the capturing of bioaerosols. For the elimination of the bounce effect and localization of the deposit in the primary zone, this empirical study proposes the solution of tailoring the smooth silicon surface with sharp pillar nanostructures (e.g., black silicon, BSi). Therefore, we show that a BSi-functionalized MEMS mass sensor–integrated impactor is suitable for the detection of micron-sized solid particles, such as Aspergillus niger spores (dae of 3.04 µm).

Collapse of the Last Eurasian Ice Sheet in the North Sea Modulated by Combined Processes of Ice Flow, Surface Melt, and Marine Ice Sheet Instabilities

The record of the confluence and collapse of the British‐Irish Ice Sheet and the Fennoscandian Ice Sheet is obscured by the North Sea, hindering reconstructions of the glacial dynamics of this sector of the Eurasian Ice Sheet complex during the last glacial cycle. Previous numerical simulations of the deglaciation of the North Sea have also struggled to capture the confluence and separation of the British‐Irish and Fennoscandian Ice Sheets. We ran an ensemble of 70 experiments simulating the deglaciation of the North Sea between 23 and 18 ka BP using the BISICLES ice sheet model. A novel suite of quantitative model‐data comparison tools was used to identify plausible simulations of deglaciation that match empirical data for ice flow, margin position, and retreat ages, allowing comparisons to large amounts of empirical data. In ensemble members that best match the empirical data, the North Sea deglaciates through the collapse of the marine‐based Norwegian Channel Ice Stream, unzipping the confluence between the British‐Irish Ice Sheet and the Fennoscandian Ice Sheet. Thinning of the Norwegian Channel Ice Stream causes surface temperature feedbacks, rapid grounding line retreat, and ice stream acceleration, further driving separation of the British‐Irish and the Fennoscandian Ice Sheets. These simulations of the North Sea deglaciation conform with the majority of empirical evidence, and therefore provide physically plausible insights that are consistent with reconstructions based on the empirical evidence, and permit a quantitative comparison between model and data.
Tracking lake surface elevations with proportional hypsometric relationships, Landsat imagery, and multiple DEMs

Multidecadal inland surface water dynamics are of increasing interest due to their importance to climate, ecology, and society, yet several key challenges impede long‐term monitoring of inland surface waters globally. This research investigates two novel methods, one addressing subhydroflattened surface estimate uncertainty issues, and a second addressing temporal resolution issues, using 46 water bodies across the western United States. First, low water level estimate uncertainty was reduced using multiple digital elevation models (ALOS, SRTM, and NED) to derive the hypsometric relationship for each lake from the digital elevation model with the lowest hydroflattened water surface. This technique reduced the number of images with subhydroflattened water surfaces by at least 549 over the best individual DEM resulting in higher water surface elevation estimate accuracy. Second, this paper introduces proportional hypsometry which dynamically generates surface area/elevation relationships for every image using clear pixels only by removing contamination from both the image and DEM. Proportional hypsometry was found to be ill‐suited for subhydroflattened water surface levels but produced comparable accuracy to clear images for above hydroflattened water levels. Overall, using the lowest hydroflattened surface along with proportional hypsometry improved temporal resolution enabling analysis of nearly 10,000 additional images while maintaining similar accuracy levels as images with <1% contamination (2.35 m RMSE vs. 2.17 m RMSE). This research increases lower water elevation estimate accuracy and temporal resolution and is scalable enabling regional and global water dynamic analysis.
