Variant septation of the sphenoid sinus in adult Nigerians: CT study

Preoperative evaluation of the sphenoid sinus septa is mandatory for safe endoscopic endonasal transsphenoidal surgery. This study aimed at elucidating the variant septation of the sphenoid sinus using computed tomographic images of adult patients. This observational study retrospectively evaluated 336 brain Computed Tomographic images of adult patients seen in a Nigerian Teaching Hospital. The study was approved by the Research Committee of the Hospital. The presence, number, location and attachment of the sphenoid sinus septum were studied and recorded. Statistical Package for Social Sciences version 23 was used to analyze the prevalence of the variants and compare them based on gender and side using the Chi-square test. The level of significance was considered at p<0.05. The prevalence of a single complete septum was 179 (53.3%), while double and multiple septa had a frequency of 88 (26.2%) and 69 (20.5%) respectively. The complete septum was predominantly located in the paramedian position (185, 69.3%). The septa attached onto the carotid canal and optic canal in 91 (27.1%) and 46 (13.7%) patients respectively. The multiple and double septa had a high predilection for the carotid (52, 75.4%) and optic (32, 36.4%) canal insertions respectively. These patterns of septation did not show any significant relationship with gender or side (P>0.05). The single septum was the most prevalent and frequent in the paramedian location, while multiple and double septa commonly insert onto the carotid and optic channels respectively.
Hydrocarbon degradation and metal remediation by hydrocarbon-utilising and metal-tolerant Klebsiella pneumoniae YSA-9 isolated from soil contaminated with petroleum

ABSTRACT Petroleum contamination of our biosphere particularly soil and water is due to the release of petroleum products from petrochemical industries. The aim of the present study was to isolate hydrocarbon-utilising and metal-tolerant bacteria capable of hydrocarbon degradation and metal remediation. Petroleum contaminated soil from which the bacteria were isolated had a total hydrocarbon concentration of 3538 mg/kg and several metals. The soil was also observed for the total bacterial population which was observed as 2.23 × 106 CFU/g of soil. Among different strains, strain YSA-9 showed the highest potential for hydrocarbon-utilisation with an absorbance of 0.920. Strain YSA-9 also displayed high tolerance to Cr (VI) and Cu up to 900 μg/ml to each metal. Strain YSA-9 was identified by 16S rRNA as Klebsiella pneumoniae. Strain YSA-9 showed a wide range of hydrocarbon degradation, degrading many hydrocarbons with the formation of new compounds and remedying higher amounts of metals. Klebsiella pneumoniae YSA-9 significantly removed Cr (VI) and Cu by biosorption at different pH, metal concentrations, temperature and the time of incubation. A wide range of hydrocarbon degradation and higher metal remediation by strain YSA-9 makes strain YSA-9 a super bio-inoculant for the remediation of polluted soils.
Mazur manifolds and corks with small shadow complexities

In this paper we find infinitely many Mazur type manifolds and corks with shadow complexity one among the 4-manifolds constructed from contractible special polyhedra having one true vertex by using the notion of Turaev's shadow. We also find such manifolds among 4-manifolds constructed from Bing's house. Our manifolds with shadow complexity one contain the Mazur manifolds $W^{\pm }(l,k)$ which were studied by Akbulut and Kirby.
Related Party Transactions and Corporate Governance in Business Group: Evidence from Indonesia

This paper aims to offer new evidence as to how sub-related party transactions (RPTs) can be related to corporate governance for Indonesia's business group. We address an ongoing theoretical tension and some recent research in the RPTs literature by focusing on revenue, expenses, loans, and receivables. Business groups are classified by size or market capitalization. This paper examines whether RPTs in the business group relate with domestic/foreign shareholders, independent board/commissioner, and firm size as controlling factors. The business groups wereselected through purposive sampling that met the analysis criteria with their typology in the population of business groups listed on IDX. We used panel data analysis for four models. This relationship is more pronounced than some recent research for business group firms and firms with more highly concentrated foreign ownership regarding the effect RPTs on revenue, expenses, loans, and receivables. Related to the controlling variable, firm size shows a significant effect on every sub RPTs. The results may imply that foreign ownership exploits Indonesia with expenses such as cross-border transactions of capital goods, intangible property (royalty), intra-firm services, and the cost of debt. Therefore, there is a need for a balanced interest for government and business in Indonesia via foreign directinvestment with corporate governance implementation and adaptive regulation.
Scaling limits for conditional diffusion exit problems, Doob's h-transform, and asymptotics for nonlinear elliptic equations

The goal of this paper is to supplement the large deviation principle of the Freidlin--Wentzell theory on exit problems for diffusion processes with results of classical central limit theorem kind. We describe a class of situations where conditioning on exit through unlikely locations leads to a Gaussian scaling limit for the exit distribution. Our results are based on Doob's h-transform and new asymptotic convergence gradient estimates for elliptic nonlinear equations that allow to reduce the problem to the Levinson case. We devote a separate section to a rigorous and general discussion of h-transform.

Two Reports on Harmonic Maps

Harmonic maps between Riemannian manifolds are solutions of systems of nonlinear partial differential equations which appear in different contexts of differential geometry. They include holomorphic maps, minimal surfaces, -models in physics. Recently, they have become powerful tools in the study of global properties of Riemannian and Kahlerian manifolds.A standard reference for this subject is a pair of Reports, published in 1978 and 1988 by James Eells and Luc Lemaire.This book presents these two reports in a single volume with a brief supplement reporting on some recent developments in the theory. It is both an introduction to the subject and a unique source of references, providing an organized exposition of results spread throughout more than 800 papers.
Perioperative Factors Impact on Mortality and Survival Rate of Geriatric Patients Undergoing Surgery in the COVID-19 Pandemic: A Prospective Cohort Study in Indonesia

Abstract Background: The COVID-19 pandemic continues to have an impact on geriatric patients worldwide since geriatrics itself is an age group with a high risk due to declined physiological function and many comorbidities, especially for those who undergo surgery. In this study, we determine the association between perioperative factors with 30-day mortality and a survival rate of geriatric patients undergoing surgery during COVID-19 pandemic. Methods: A prospective cohort study was conducted at 14 central hospitals in Indonesia. The recorded variables were perioperative factors, 30-day mortality, and survival rate. Analyses of associations between variables and 30-day mortality were performed using univariate/multivariable logistic regression, and survival rates were determined with Kaplan–Meier survival analysis. Results: We analyzed 1621 elderly patients. The total number of patients who survived within 30 days of observation was 4.3%. Several perioperative factors were associated with 30-day mortality (p < 0.05) is COVID-19 (OR, 4.34; 95% CI, 1.04–18.07; p = 0.04), CCI > 3 ( odds ratio [OR], 2.33; 95% confidence interval [CI], 1.03–5.26; p = 0.04), emergency surgery (OR, 3.70; 95% CI, 1.96–7.00; p ≤ 0.01), postoperative ICU care (OR, 2.70; 95% CI, 1.32–5.53; p = 0.01), and adverse events (AEs) in the ICU (OR, 3.43; 95% CI, 1.32–8.96; p = 0.01). Aligned with these findings, COVID-19, CCI > 3, and comorbidities have a log-rank p < 0.05. The six comorbidities that have log-rank p < 0.05 are moderate-to-severe renal disease (log-rank p ≤ 0.01), cerebrovascular disease (log-rank p ≤ 0.01), diabetes with chronic complications (log-rank p = 0.03), metastatic solid tumor (log-rank p = 0.02), dementia (log-rank p ≤ 0.01), and rheumatology disease (log-rank p = 0.03). Conclusions: Having at least one of these conditions, such as COVID-19, comorbidities, emergency surgery, postoperative ICU care, or an AE in the ICU were associated with increased mortality in geriatric patients undergoing surgery during the COVID-19 pandemic.
Coexistent Detrusor Overactivity-Underactivity in Patients with Pelvic Floor Disorders

Introduction and Hypothesis: Pelvic floor disorders represent a series of conditions that share, in part, the same etiological mechanisms, so they tend to be concomitant. Recently, awareness of a new lower urinary tract clinical syndrome has risen, namely the coexisting overactive–underactive bladder (COUB). The etiopathogenetic process, prevalence, and related instrumental findings of COUB are not well-established. We aimed to evaluate the prevalence, clinical features, and urodynamic findings of patients with COUB in a large cohort of patients with pelvic floor disorders. Methods: A cohort of 2092 women was retrospectively analyzed. A clinical interview, urogenital examination, and urodynamic assessment were performed by a trained urogynecologist. Based on baseline symptoms, patients were divided into COUB and non-COUB groups, and the degree of concordance between COUB and urodynamic findings, and other parameters related to the clinical aspects of these patients were measured and analyzed. Results: 18.8% of patients were classified as COUB. The association between COUB and patients with coexisting detrusor overactivity–underactivity (DOU) was statistically significant and there were substantial similarities in terms of population characteristics, symptoms, and urodynamic findings. Conclusions: Our study showed a high prevalence of COUB, and a link between this clinical syndrome and DOU was demonstrated. They showed substantial similarities in terms of clinical and urodynamics correlates. Based on these findings, we do think that urodynamic tests can be useful to improve knowledge on COUB and may be of help in the management of this condition.
How Does a Face Mask Impact Speech Perception?

Face masks are mandatory during the COVID-19 pandemic, leading to attenuation of sound energy and loss of visual cues which are important for communication. This study explores how a face mask affects speech performance for individuals with and without hearing loss. Four video recordings (a female speaker with and without a face mask and a male speaker with and without a face mask) were used to examine individuals’ speech performance. The participants completed a listen-and-repeat task while watching four types of video recordings. Acoustic characteristics of speech signals based on mask type (no mask, surgical, and N95) were also examined. The availability of visual cues was beneficial for speech understanding—both groups showed significant improvements in speech perception when they were able to see the speaker without the mask. However, when the speakers were wearing the mask, no statistical significance was observed between no visual cues and visual cues conditions. Findings of the study demonstrate that provision of visual cues is beneficial for speech perception for individuals with normal hearing and hearing impairment. This study adds value to the importance of the use of communication strategies during the pandemic where visual information is lost due to the face mask.
Galactic disk abundance ratios: constraining SNIa stellar yields

Stellar abundance ratios of very good quality are now available for a large number of stars in the solar vicinity. Moreover, for an increasing number of stars informations on kinematics is also available. The combined information on abundance and kinematics enables one to select objects belonging to the different components of our Galaxy (thin disk, thick disk and halo). In this work we show that a careful comparison of our chemical evolution model for the Milky Way with the available abundance ratio measurements for stars in the solar neighborhood can be used to constrain the stellar yields. In particular, yields of Type Ia SNe are constrained by the abundance pattern of thin disk stars. Our results suggest that the 3‐D models for SNIa explosion studied here lead to discrepancies once their predicted stellar yields are used as input in our chemical evolution model. These models produce flat Si/O and Mg/O ratios in disagreement with what is observed in thin disk stars. Moreover, our results indicate that larger quantities of Mg (at least a factor of 10 more than current theoretical predictions of either 1‐D or multi‐D models) need to be produced in SNIa.
In Vitro Polyploid Induction of Highbush Blueberry through De Novo Shoot Organogenesis

Polyploid induction is of utmost importance in horticultural plants for the development of new varieties with desirable morphological and physiological traits. Polyploidy may occur naturally due to the formation of unreduced gametes or can be artificially induced by doubling the number of chromosomes in somatic cells. In this experiment, a protocol for in vitro polyploid induction of highbush blueberry (Vaccinium corymbosum L.) leaf tissues was studied by using different concentrations of colchicine and oryzalin. Oryzalin was found to be highly toxic to this species, while the adventitious shoot organogenesis media enriched with 25 and 250 µM colchicine was able to induce polyploidization, with significant differences among the treatments used. Higher concentrations of both antimitotic agents led to the browning and death of the leaf tissues. The polyploids obtained showed several morphological differences when compared with the diploid shoots. Flow cytometry analysis was used to confirm the ploidy level of the regenerated shoots, demonstrating that a total of 15 tetraploids and 34 mixoploids were obtained. The stomatal sizes (length and width) of the tetraploids were larger than those of the diploids, but a reduced stomatal density was observed as compared to the controls. These shoots will be acclimatized and grown until they reach the reproductive phase in order to test their potential appeal as new varieties or their use for breeding and genetic improvement.
Molecular biomarkers in Batagay megaslump permafrost deposits reveal clear differences in organic matter preservation between glacial and interglacial periods

Abstract. The Batagay megaslump, a permafrost thaw feature in north-eastern Siberia, provides access to ancient permafrost up to ∼650 kyr old. We aimed to assess the permafrost-locked organic matter (OM) quality and to deduce palaeo-environmental information on glacial–interglacial timescales. We sampled five stratigraphic units exposed on the 55 m high slump headwall and analysed lipid biomarkers (alkanes, fatty acids and alcohols). Our findings revealed similar biogeochemical signatures for the glacial periods: the lower ice complex (Marine Isotope Stage (MIS) 16 or earlier), the lower sand unit (sometime between MIS 16–6) and the upper ice complex (MIS 4–2). The OM in these units has a terrestrial character, and microbial activity was likely limited. Contrarily, the n-alkane and fatty acid distributions differed for the units from interglacial periods: the woody layer (MIS 5), separating the lower sand unit and the upper ice complex, and the Holocene cover (MIS 1), on top of the upper ice complex. The woody layer, marking a permafrost degradation disconformity, contained markers of terrestrial origin (sterols) and high microbial decomposition (iso- and anteiso-fatty acids). In the Holocene cover, biomarkers pointed to wet depositional conditions and we identified branched and cyclic alkanes, which are likely of microbial origin. Higher OM decomposition characterised the interglacial periods. As climate warming will continue permafrost degradation in the Batagay megaslump and in other areas, large amounts of deeply buried ancient OM with variable composition and degradability are mobilised, likely significantly enhancing greenhouse gas emissions from permafrost regions.
Evidence of partial gap opening and Ce-site dilution effects in a heavy fermion compound CeNiGe2

ABSTRACT We report the results of magnetisation, non-linear dc susceptibility, electrical transport, and heat capacity measurements on Y-substituted heavy fermion CeNiGe2. Investigations are carried out on the compounds CeNiGe2, Ce0.9Y0. 1NiGe2, Ce0.8Y0. 2NiGe2 and Ce0.6Y0. 4NiGe2. It is observed that with the increase in Y-concentration, the magnetic ordering temperature decreases. For CeNiGe2, below ordering temperature Arrott plots suggest the presence of spin density wave (SDW). Third- and fifth-order dc susceptibility indicates magnetic instability which possibly leads to partial gap opening resulting in the observation of SDW. These observations are further investigated through resistivity and heat capacity measurements which also point toward partial gap opening in CeNiGe2. Interestingly, with the increase in Y-substitution, it is noted that the gap opening is suppressed and also shifted towards lower temperature. Moreover, our investigations reveal absence of non-Fermi liquid behaviour or zero field quantum critical point even after 40% dilution of Ce-site.
Strategi Komunikasi Penerapan Protokol Kesehatan Covid-19 di Masjid Agung Asy-Syuhada’ Pamekasan

This study aims to describe the communication strategy of the management of the Great Mosque of Asy-Syuhada' Pamekasan in implementing the Covid-19 health protocol and to describe maintaining distance when praying together in Islam during a pandemic. This research uses descriptive qualitative method. The result shows that the communication strategy used by the management of the Great Mosque of Asy-Syuhada' Pamekasan is in accordance with the components in the communication formulation in the Laswell concept, Who Says What in Which Channel to Whom With What Effect, which included communicator, message, media, communicant, and effect. The implementation of the health protocol is conveyed to the community or congregation by the mosque management in oral, written and electronic form and had an effect in which the congregation finally complied with the health protocol. Meanwhile, the legal case for keeping a distance in prayer is based on the letter Al-Baqarah verse 195, the hadith of the Prophet Muhammad SAW, and the rule of ushul fiqh. In this case, the case of keeping a distance in congregational prayers during the Covid-19 pandemic is allowed as an effort to prevent the transmission and spread of the virus.
The Value of Sustainable Tourism Destinations in the Eyes of Visitors

The first objective of this study is to analyze visitors’ perceived value of four Italian small areas, that have been granted the European Regional Development Fund’s financing for developing sustainable tourism. The second objective of this work is to investigate the influences of socio-demographic and trip-related characteristics on the tourists’ assessments of the main aspects of such destinations, for detecting variables useful for market segmentation and for designing better-targeted marketing actions. These areas host protected natural reserves, historical heritage, rural or mountain traditions, and ways of life, the conservation of which is combined with local economic growth through the development of green, cultural, and slow tourism. Thus, insights on how visitors’ perceived value is configured there might provide hints useful for upgrading the local tourism supply consistently with the United Nations’ Agenda 2030 for sustainable development and the European Green Deal Strategy. Results confirm that the perceived value is a fundamental construct, as it strongly and positively influences satisfaction, intention to recommend, and destination image. The value of sustainable destinations, as perceived by visitors, is mainly based on the affective benefits that sustainable experiences provide, starting from positive social interactions making tourists feel welcomed. The tourist segment valorizing sustainable destinations is mostly composed of old people and low-income travelers, who seek basic services and facilities, as their satisfaction depends mainly on relaxing immersed in pristine nature.
Inequalities in the prevalence of cardiovascular disease risk factors in Brazilian slum populations: A cross-sectional study

Background Social and environmental risk factors in informal settlements and slums may contribute to increased risk of cardiovascular disease (CVD). This study assesses the socioeconomic inequalities in CVD risk factors in Brazil comparing slum and non-slum populations. Methods Responses from 94,114 individuals from the 2019 Brazilian National Health Survey were analysed. The United Nations Human Settlements Programme definition of a slum was used to identify slum inhabitants. Six behavioural risk factors, four metabolic risk factors and doctor-diagnosed CVD were analysed using Poisson regression models adjusting for socioeconomic characteristics. Results Compared to urban non-slum inhabitants, slum inhabitants were more likely to: have low (less than five days per week) consumption of fruits (APR: 1.04, 95%CI 1.01–1.07) or vegetables (APR: 1.08, 95%CI 1.05–1.12); drink four or more alcoholic drinks per day (APR: 1.05, 95%CI 1.03–1.06); and be physically active less than 150 minutes per week (APR: 1.03, 95%CI 1.01–1.04). There were no differences in the likelihoods of doctor-diagnosed metabolic risk factors or CVD between the two groups in adjusted models. There was a higher likelihood of behavioural and metabolic risk factors among those with lower education, with lower incomes, and the non-White population. Conclusions Brazilians living in slums are at higher risk of behavioural risk factors for CVD, suggesting local environments might impact access to and uptake of healthy behaviours.
