ASSESSMENT OF MEAN DISTANCE BETWEEN CENTRAL INCISOR AND INCISIVE PAPILLA WITH RESPECT TO STANDARDIZED ARCH FORM IN DENTATE SUBJECTS

BACKGROUND & OBJECTIVE: Edentulous patients require accurate positioning of artificial maxillary anterior teeth in complete dentures to recover the esthetic and phonetic characteristics. This positioning is guided by measuring distance between central incisor (CI) and incisive papilla (IP) in dentate subjects which varies according to the ovoid, square and tapered maxillary arch forms. Objectives: 1- To determine the frequency of three different arch forms in dentate patients; 2- To assess the mean distance between central incisor and incisive papilla in each of the three maxillary arch forms. METHODOLOGY: 130 cases were selected by non-probability consecutive sampling, which included both genders and age range of 20-40 years. Impressions of maxillary arches were recorded and their casts photocopied. Arch form template was used to standardize the assessment of arch forms by best-fit method on the photocopies. The distance between mesio-incisal edge of CI and posterior border of IP was measured with digital verniercalipers (SparkFun,Colorado). RESULTS: Out of 130 subjects, 54 males and 76 females were present. The ovoid arch form was the most frequent form recorded at 67% (n=87) while the tapered arch was the least at 14% (n=18). The overall mean distance between central incisor (CI) and incisive papilla (IP) was 11.34mm (7.58mm - 16.45mm). The mean distance was the highest for ovoid arch form (11.58mm) and lowest for square (10.49) with a statistically significant difference (p=0.016) between the two arch forms. CONCLUSION: The ovoid arch was the most frequent arch form found in dentate subjects. The mean distance recorded was highest for ovoid arch followed by tapering arch and least for square arches.
The mediating role of achievement emotions in the relationship between instructional clarity, English proficiency, and reading strategies

Abstract Reading ability has had a prominent role in English language education in Taiwan. The comprehension of materials and teacher instruction in English depends on students’ English proficiency, and their achievement emotions regarding competence-related activities may influence how they read and complete tasks in English. This study aims to investigate the mediating role of positive and negative achievement emotions in the relationship between instructional clarity, English proficiency, and reading strategies. A questionnaire survey was conducted with 640 university students in Taiwan. The findings corroborated control-value theory. The structural model revealed that the participants’ use of reading strategies was strongly influenced by teachers’ instructional clarity and students’ English reading proficiency. Only positive emotions mediated the relation between instructional clarity, English proficiency, and reading strategies. Negative emotions, though correlated with the two predictors and the reading strategies, did not mediate the relationship between them.
Excellence in Sustainable Management in a Changing Environment

In the current changing environment, organizations need to evolve from a profitable perspective to a more sustainable focus. To deal with this change, the implementation of specific quality models and principles might help. Thus, the present article aims to study whether sustainable management can be achieved in specific organizations (enterprises, associations, and government institutions) by identifying the EFQM principles. Moreover, it analyses which of these quality principles positively and directly impacts the performances studied (environmental, social, and economic). To achieve these objectives, Ordinal Logistic Regression (ORL) was performed using data corresponding to the sample compiled by the Càtedra Universitària de Responsabilitat Social (RSU) from University of Girona. The research results indicate that implementing specific quality principles all the dimensions improved; thus, the organization becomes more sustainable. The value of this research lies in its contribution to the sustainable management literature; adds knowledge to the ongoing debate about the possible influence of TQM principles on the specific dimensions of sustainable management and highlight the importance of having a clear strategy to obtain the highest sustainable performance.
Analytical approaches for discriminating native lard from other animal fats

Establishing the distinguishable characteristics of lard from other common animal fats might be helpful for authentication initiatives in foods and feeds. In this study, fatty acid and triacylglycerol compositions, thermal and spectroscopic characteristics of native lard (NL), respectively, were compared with those of beef tallow (BT), mutton tallow (MT), and chicken fat (CF) by using gas liquid chromatography (GLC), high-performance liquid chromatography (HPLC), and differential scanning calorimetry (DSC). GLC analysis showed that the comparison of the overall fatty acid data might not be suitable for the discrimination of different animal fats, but the use of the principal component analysis and the percent palmitic acid enrichment factor [PAEF (%)] calculations were useful. HPLC analysis showed that NL displayed a TAG profile, which was quite different from those of either BT or MT, but appeared to be closely similar to that of CF. Results of DSC thermal analysis showed that both melting and crystallization curves of NL were remarkably different from those of other animal fats.
Effect of Rainfall and pH on Musty Odor Produced in the Sanbe Reservoir

Harmful cyanobacterial blooms (HCBs) are continuously formed in water systems such as reservoirs and lakes around the world. In particular, geosmin and 2-methylisoborneol (2-MIB), which are made by cyanobacteria, have caused serious musty-odor problems in the drinking water of the Sanbe reservoir in Japan. To investigate the cause of this musty odor, we conducted field observations for five years (2015–2019). As a result, it was determined that the geosmin was caused by the cyanobacteria as Dolichospermum crassum and Dolichospermum planctonicum, and 2-MIB was caused by the cyanobacteria as Pseudanabaena sp and Aphanizomenon cf. flos-aquae. It was also determined that the occurrence of geosmin and 2-MIB are influenced by changes in water temperature and pH due to the inflow of rainfall. Especially, the geosmin and 2-MIB tended to occur in low rainfall conditions. When there is low rainfall, the reservoir changes to an alkaline state due to the consumption of CO2 by the photosynthesis of phytoplankton. In an alkaline reservoir, CO2 exists in the form of bicarbonate (HCO3-); thus, under these condition cyanobacteria will increase because it uses both CO2 and bicarbonate (HCO3-) for photosynthesis. Our study suggests that for solving the musty-odor problem in the reservoir, it is important to control the reservoir’s pH. Moreover, more focus should be place in managing the water quality problem of the Sanbe Reservoir, especially, during low rainfall years. The results of this study will help in addressing odor related water quality problem in other reservoirs.
Does the Croatian Stock Market Have Seasonal Affective Disorder?

This paper explores mood anomalies, specifically the seasonal affective disorder (SAD) effect on the Zagreb Stock Exchange (ZSE). SAD is defined as a syndrome of depressive episodes in human behavior due to the changing of the season. Thus, the motive of this research is to gain better insights into the investors’ sentiment regarding SAD effects. The purpose of the research is to observe how investors’ sentiment affects the return and risk series on ZSE and if this could be exploitable. Using daily data on stock market return CROBEX for the period January 2010—February 2021, SAD effects are tested to explore if seasonal changes affect the stock returns and risk. Besides the SAD variable in the model, some control variables are included as well: Monday, tax, and COVID-19 effect. The results indicate that SAD effects exist on ZSE, even with controlling for mentioned effects; and asymmetries around winter solstice exist. Implications of such findings can be found in simulating trading strategies, which could incorporate such information to gain profits. Limitations of the research focus on one market, observing static parameters of the estimated models, and observing simple trading strategies. Thus, future research should focus on international diversification possibilities, time-varying models, and fully exploring the exploitation possibilities of such findings.
Evidence for centennial‐scale Lateglacial and early Holocene climatic complexity from Quoyloo Meadow, Orkney, Scotland

The influence of the North Atlantic on the margins of Europe means the region is particularly sensitive to changes in the ocean–atmospheric system. During the Last Glacial–Interglacial Transition (16–8 cal ka bp) this system was repeatedly disrupted, leading to a series of abrupt and short‐lived shifts in climate. Despite much research, the number and magnitude of these ‘centennial‐scale’ events is not well understood. To address this, we expand upon investigations at Quoyloo Meadow, Orkney, Scotland, one of the best chronologically constrained palaeoclimate records in northern Britain. By coupling stable isotope and chironomid fossil analyses with existing data, this study identifies multiple phases of centennial‐scale disturbance at: c. 14.0, 11.1, 10.8, 10.5, 10.45 and 10.3 cal ka bp, with the events at 14.0 and 10.3 exhibiting a particularly pronounced cold‐climate signature. During the Holocene, the strongest response to climate forcing was at c. 10.3–10.0 cal ka bp, expressed as a two‐stage drop in mean July temperatures, a shift in pollen spectra indicative of ‘less‐stable’ climatic regimes, and a depletion in δ18O values. We interpret this as the first reliably dated incidence of the ‘10.3‐ka event’ in the British Isles and consider the wider impact of this climatic reversal in other Holocene records.
Sensitive Dependence of Ultrarelativistic Electron Precipitation on EMIC Wave Frequency

Electromagnetic ion cyclotron (EMIC) waves have long been considered to cause atmospheric precipitation loss of relativistic electrons, the quantitative evaluation of which is critical for understanding the radiation belt electron flux dropouts. In this study, we report test particle calculation results on precipitation loss rates of 5 MeV electrons with initial pitch angles of 4–10° at the equator by He+ band EMIC waves. We find a sensitive dependence of the precipitation loss rates on the wave frequency in that a preferred wave frequency (maximum loss frequency) exists at which the loss rate peaks predominantly and away from which it declines substantially. According to a cold plasma dispersion relation, a small difference in wave frequency just below the He+ gyrofrequency corresponds to a significant difference in wavenumber. Different frequencies lead to phase trapping of different extents, which determines the significance of loss cone scattering at the exit latitude from the wave zone. At frequencies below the maximum loss frequency, phase trapping causes large advective pitch angle changes, prohibiting loss cone scattering. At the maximum loss frequency, the phase‐trapping effect is optimized such that diffusion is dominant over advection and large enough to allow effective loss cone scattering. At frequencies above the maximum loss frequency, the phase‐trapping effect disappears, and the resulting (both diffusive and advective) scattering is too weak to drive loss cone scattering unless the initial pitch angle is close enough to the loss cone angle.
Using situation awareness measures to characterize mental models in an inductive reasoning task

Abstract The objective of this study was to develop and validate an empirical method of situation awareness (SA) assessment for characterizing mental models in an inductive reasoning task. We conducted an experiment in which participants watched videos of two detective stories while simultaneously playing a simple shooting game. Participant SA was measured during the trial and post-trial measures included concept mapping and knowledge tests on the stories. A fuzzy inference model was developed to classify SA measurement outcomes according to patterns that matched with hypothesized types of mental models. The model type identification, based on fuzzy inference, revealed utility for predicting knowledge test performance. The fuzzy model outputs and SA measures were found to be independent from (or complementary to) concept map measures. The results provided empirical evidence of the utility of SA measures for inferring forms of mental models and predicting knowledge of an inductive reasoning task, independent of an existing assessment approach (concept mapping).
Impact of Inverter Based Resources on System Protection

Inverter-based resources (IBRs) exhibit different short-circuit characteristics compared to traditional synchronous generators (SGs). Hence, increased uptake of IBRs in the power system is expected to impact the performance of traditional protective relay schemes—set under the assumption of a SG-dominated power system. Protection engineers need to study these challenges and develop remedial solutions ensuring the effectiveness of system protection under higher levels of IBRs. To address this need, this paper studies the impact of IBRs on a variety of protective relay schemes including line distance protection, memory-polarized zero sequence directional protective relay element, negative sequence quantities-based protection, line current differential protection, phase comparison protection, rate-of-change-of-frequency, and power swing detection. For each protection function, potential misoperation scenarios are identified, and recommendations are provided to address the misoperation issue. The objective is to provide an improved understanding of the way IBRs may negatively impact the performance of traditional protection schemes as a first step towards developing future remedial solutions ensuring effective protection under high share of IBRs.
Non-parametric estimation of the extropy and the entropy measures based on progressive type-II censored data with testing uniformity

ABSTRACT The extropy measure is a complementary dual function of Shannon entropy which was proposed by Lad et al. Extropy: complementary dual of entropy. Stat Sci. 2015;30:40–58. This measure of uncertainty have received a considerable attention in the last five years. In this paper, several methods of estimation for the extropy and entropy measures based a progressively Type-II censored data are derived. Simulation studies have been performed to see the effectiveness of the proposed methods, and two real data sets have been analysed for illustrative purposes. Extropy and entropy-based tests of uniformity are also proposed along with their simulated critical values. The power values of the proposed tests are simulated and studied under various alternatives.
Lithium-ion capacitors based on in-situ pre-lithiation of the graphite electrode from a composite positive electrode

Adaptation of pre-lithation protocol with the use of the lithium ions originating from the composite postive electrode and determination of maximum operating voltage for an lithium-ion capacitor operating in organic electrolyte (LiPF6 ) have been done. Possible factors contributing to improvement in the electrochemical performance of the lithium-ion capacitor (LIC) in organic solution with use of compocite postive electrode as the internal source of lithium ions have been recognized. Alterations in compositon of the positive and negative electrode as intorduction of carbon nanotubes, use of different sacrifical lithium sourcesa or change of electrochemical condtions during formation of solid electrolyte interphase (S.E.I.), were revealed. Strategies to improve the cycle-life of LIC in oragnic electrolyte lithium heksafluorophosphate, essentially the proper equlibration of the electrode masses, adjusting the operational voltage, or pre-lithation condtions have been presented. Furthermore, a concept of lithium-ion capacitor pouch cell by implementing one of the configurations has been presented together with possible improvments.
Abdominal tuberculosis requiring surgical intervention: A 10-year single-center experience

Background: Although uncommon in children, abdominal tuberculosis (ATB) can be a life-threatening condition with a subset requiring emergency surgical intervention. This study aims to determine the presentation, surgical procedures performed, and outcomes in children affected by abdominal tuberculosis. Methods: A retrospective chart review of all children undergoing surgical intervention for ATB from July 2007 to December 2018 was conducted. Data were analyzed using SPSS version 22. Results: Of 340 children with a diagnosis of ATB seen at the Indus Hospital’s TB clinic, 14 (4%) underwent laparotomy. Females were affected more commonly (57%), with a mean age at presentation of 11 years (range 8-14). Nine children required laparotomy for documented perforation, while 5 had an intestinal obstruction. Most children (n=10) had an established diagnosis of ATB before the surgical intervention; 2 children had completed 6–9 months anti-tuberculous treatment (ATT) courses, while 8 children had been on ATT for a mean period of 2.5 months at the time of developing acute surgical symptoms. Diversion ileostomy was made in 64%. Postoperative complications included sepsis (n=4), wound infection (n=3), abdominal collection (n=2), enterocutaneous fistula (n=2), and abdominal wound dehiscence requiring formal closure (n=2). There were 4 mortalities (29%); 10 patients were discharged after a median in-hospital stay of 12 days (range 6-35) of which 6 with ileostomies underwent reversal after completion of the ATT course. Conclusion: ATB has high morbidity and mortality. Perforation and obstruction can occur during or after the completion of ATT. Management requires early recognition and surgical intervention as indicated.
Fermentable carbohydrate metabolism in maguey mezcalero potosino (Agave salmiana): HPLC characterization and evaluation

The maguey mezcalero potosino (Agave salmiana) is a natural resource of great regional importance, used for the manufacture of mezcal and other alcoholic beverages by fermentation of simple sugars and sugars released by fructans hydrolysis. For this, only the stem and base of leaves is used, which results on wasting the other sections that represent up to 40% of weight of the complete plant. The objective of this study was to identify and quantify the fermentable carbohydrates present in raw and hydrolysed juices of the stem and four sections of the whole leaves (base, neck, wings and apex) of maguey plants with representative specimens of three stages of maturity with industrial importance. For carbohydrate characterization, high resolution liquid chromatography (HLPC) was used. The sugars found as fructose, glucose, sucrose, xylose and maltose coincide with those identified in other Agave species, significant differences are observed depending on the section and the state of maturity of the plant, the sugar concentration in the discarded sections of the plant (fructose: 5.79 – 4.80 mg mL) are considerable and statistically similar to those found in the stem (fructose: 2.49 mg mL) and the base of the leaf (fructose: 3.16 mg mL) (structure used in the mezcal production process). The results obtained can promote the integral use of the plant and diversification towards other industries such as pharmaceuticals, biofuels or foods.
Impact of sulfur and boron fertilization on yield, quality of crop and nutrient use efficiencies in rapeseed in subtropical acidic soil of Assam, India

Abstract Field experiments were conducted with rapeseed (cv.TS-38) for three consecutive rabi seasons of the year 2014–2017 at the Instructional-cum-Research farm of Assam Agriculture University, Jorhat. Results revealed that different levels of sulfur and boron and their combinations had significant influence on seed and stover yields of rapeseed. The highest seed and stover yields were registered in interaction effect of B and S at 20 kg S/ha + 1.5 kg B/ha which was closely followed by interaction effect of B and S at 30 kg S/ha + 1.5 kg B/ha. The highest total uptake of N and B was noted under 30 kg S/ha + @ 1.5 kg B/ha. The highest total S uptake was noted under application of 20 kg S/ha + @ 1.5 kg B/ha. Partial factor productivity of N, P and K increased with subsequent increase in levels of S and B up to 20 kg S/ha and 1.5 kg B/ha, respectively. The highest values of agronomic use efficiency and apparent recovery of S and B were registered under 10 kg S/ha and 0.5 kg B/ha, respectively. The highest values of physiological use efficiency of S and B were registered under 20 kg S/ha and 0.5 kg B/ha, respectively. Interaction effect of S and B at 30 kg S/ha + 1.0 kg B/ha (S30B1.0) improved the oil content to the tune of 35.6%, registering an improvement of 13.4% over the control. The same interaction resulted in enhancement of protein content up to 22.9% over the 19.8% (control) wherein 15.6% increase over the control was noticed. Multiple stepwise regressions exercised on the different nutrient uptakes showed that nitrogen content in seed contributed the most in augmenting the biological yield of rapeseed followed by phosphorus and sulfur.
Crustal Structure of the Eastern Anatolia Region (Turkey) Based on Seismic Tomography

Here, we investigated the crustal structure beneath eastern Anatolia, an area of high seismicity and critical significance for earthquake hazards in Turkey. The study was based on the local tomography method using data from earthquakes that occurred in the study area provided by the Turkiye Cumhuriyeti Ministry of Interior Disaster and Emergency Management Directorate Earthquake Department Directorate of Turkey. The dataset used for tomography included the travel times of 54,713 P-waves and 38,863 S-waves from 6355 seismic events. The distributions of the resulting seismic velocities (Vp, Vs) down to a depth of 60 km demonstrate significant anomalies associated with the major geologic and tectonic features of the region. The Arabian plate was revealed as a high-velocity anomaly, and the low-velocity patterns north of the Bitlis suture are mostly associated with eastern Anatolia. The upper crust of eastern Anatolia was associated with a ~10 km thick high-velocity anomaly; the lower crust is revealed as a wedge-shaped low-velocity anomaly. This kind of seismic structure under eastern Anatolia corresponded to the hypothesized existence of a lithospheric window beneath this collision zone, through which hot material of the asthenosphere rises. Thus, the presented results help to clarify the deep structure under eastern Anatolia.
