On the importance of moisture conveyor belts from the tropical eastern Pacific for wetter conditions in the Atacama Desert during the mid-Pliocene
Authors: Reyers Mark , Fiedler Stephanie , Ludwig Patrick , Böhm Christoph , Wennrich Volker , Shao Yaping
Published: February 2023

Abstract. Geomorphic and sedimentologic data indicate that the climate of today's hyper-arid Atacama Desert (northern Chile) was more humid during the mid-Pliocene to Late Pliocene. The processes, however, leading to increased rainfall in this period are largely unknown. To uncover these processes we use both global and regional kilometre-scale model experiments for the mid-Pliocene (3.2 Ma). We found that the PMIP4–CMIP6 (Paleoclimate Modelling Intercomparison Project–Coupled Model Intercomparison Project) model CESM2 (Community Earth System Model 2) and the regional model WRF (Weather Research and Forecasting) used in our study simulate more rainfall in the Atacama Desert for the mid-Pliocene in accordance with proxy data, mainly due to stronger extreme rainfall events in winter. Case studies reveal that these extreme winter rainfall events during the mid-Pliocene are associated with strong moisture conveyor belts (MCBs) originating in the tropical eastern Pacific. For present-day conditions, in contrast, our simulations suggest that the moisture fluxes rather arise from the subtropical Pacific region and are much weaker. A clustering approach reveals systematic differences between the moisture fluxes in the
present-day and mid-Pliocene climates, both in strength and origins. The two mid-Pliocene clusters representing tropical MCBs and occurring less than 1 d annually on average produce more rainfall in the hyper-arid core of the Atacama Desert south of 20∘ S than what is simulated for the entire present-day period. We thus conclude that MCBs are mainly responsible for enhanced rainfall during the mid-Pliocene. There is also a strong sea-surface temperature (SST) increase in the tropical eastern Pacific and along the Atacama coast for the mid-Pliocene. It suggests that a warmer ocean in combination with stronger mid-tropospheric troughs is beneficial for the development of MCBs leading to more extreme rainfall in a +3 ∘C warmer world like in the mid-Pliocene.
Proposal of an instrument design to observe annual changes in Spectral Outgoing Radiation
Authors: Schmidtke Gerhard Georg Bruno , Brunner Raimund , Jacobi Christoph
Published: February 2023

Abstract. From the wide range of possibilities, we propose an instrument capable of measuring annual changes in global Spectral Outgoing Radiation (SORa) from the entire Earth's surface between 200 nm and 1100 nm with a stability of 0.1 Wm-2 over a period of one solar cycle or beyond. Photomultiplier tubes (PMTs) as detectors provide data with a cadence of one second and high dynamic range. Based on Total Solar Radiation TSI(t) data with a stability of 0.01 Wm-2 per year, Spectral Solar Irradiance SSI(t) can be derived and normalized to ΣSSI(t)=TSI(t) for using the Sun as a referenced radiation source supported by solar modeling. Calibrated by SSI(t), a set of 12 spectrometers with 60 PMTs in total and 16 photometers simultaneously detect SOR(t). This database can also be provided to calibrate other space instruments to allow improved comparison of results. In previous missions in space, it has already been shown that the spectrometer design can detect both solar and terrestrial radiation with high dynamic range. The established measurement technique compensates for degradation through repeated calibration. The instrument also enables the determination of the global green Earth coverage and its annual changes by measuring chlorophyll absorption from 350 nm to 490 nm and 620 nm to 690 nm and green backscatter from 500 nm to 600 nm. Mapping the Earth will also make it possible to track annual local changes in green coverage and to assess the impact of different climate policies and climate engineering actions. Another aspect is the derivation of a correction parameter for the Earth Energy Imbalance derived from changes in green areas. Data evaluation can also include determining further parameters such as the Normalized Difference Vegetation Index, the Enhanced Vegetation Index, and the Global Leaf Area Index.
CO2 diffusion in dry and hydrous leucititic melt
Authors: Koch Lennart , Schmidt Burkhard C.
Published: February 2023

Abstract. Using the diffusion couple technique, diffusion of
CO2 in a leucititic melt from the Colli Albani Volcanic District in
Italy was investigated at temperatures between 1200 and 1350 ∘C
in an internally heated pressure vessel at 300 MPa. To examine the effect of
dissolved H2O in the melt, experiments were performed for a nominally
dry melt (0.18 ± 0.03 wt % H2O) and for a hydrous melt
containing 3.36 ± 0.28 wt % H2O. Diffusion experiments were run
for 40 to 120 min and terminated by rapid quench. CO2 concentration
profiles were subsequently measured via attenuated total reflection
Fourier transform infrared spectroscopy (ATR-FTIR) and fitted with error
functions to obtain individual diffusion coefficients. For the anhydrous and hydrous sample series, seven diffusion coefficients
were determined each. Diffusivity was found to increase exponentially with
temperature for both melts following an Arrhenius behaviour. The Arrhenius
equation for the nominally dry leucititic melt is described by log⁡DCO2=-1.44(±0.24)⋅10000T-1.95(±1.59), where DCO2 is the diffusion coefficient in m2 s−1 and T is the
temperature in K. In the experimental temperature range, H2O has an
accelerating effect on CO2 diffusion. At 1200 ∘C,
diffusivity increases from 1.94 × 10−12 m2 s−1 in
the dry melt to 1.54 × 10−11 m2 s−1 in the hydrous
melt. The Arrhenius equation for the leucititic melt containing 3.36±0.28 wt % H2O is given by log⁡DCO2=-1.09(±0.30)⋅10000T-3.41(±1.99). The activation energies for CO2 were determined to be 275 ± 47 kJ mol−1 for the anhydrous melt and 209 ± 58 kJ mol−1 for the
hydrous melt. The high CO2 activation energy in the leucititic melt indicates that
the diffusion might be partly attributed to the carbonate species. At high
magmatic temperatures above 1200 ∘C, CO2 diffusivity in the
leucititic melt is only slightly lower than CO2 diffusion in rhyolitic
and basaltic melts, suggesting that CO2 diffusion in natural melts is
relatively independent from the bulk melt composition at such temperatures.
CO2 diffuses slower than other volatile components such as halogens and
H2O in depolymerized silicate melts. Thus, a fractionation of volatiles
can occur during magma ascent and degassing. The experimental data on
CO2 diffusion can be used for modelling the degassing mechanisms of
ultrapotassic mafic melts.
Improving the predictability of the Qendresa Medicane by the assimilation of conventional and atmospheric motion vector observations. Storm-scale analysis and short-range forecast
Authors: Carrió Diego S.
Published: February 2023

Abstract. The coastal population in the western Mediterranean Basin is frequently affected by high-impact weather events that produce huge economic and human losses. Among the wide spectrum of maritime severe weather events, tropical-like Mediterranean cyclones (a.k.a. medicanes) draw particular attention, specially due to their poor predictability. The accurate prediction of this kind of event still remains a key challenge to the weather forecast community, mainly because of (i) errors in the initial conditions, (ii) lack of accuracy of modeling micro-scale physics processes and (iii) chaotic behavior inherent to numerical weather prediction models. The 7 November 2014 Qendresa Medicane, that took place over the Sicilian channel affecting the islands of Lampedusa, Pantelleria and Malta, was selected for this study because of its extremely low predictability behavior in terms of its track and intensity. To enhance the prediction of Qendresa, a high-resolution (4 km) ensemble-based data assimilation technique, known as ensemble Kalman filter (EnKF), is used. In this study, both in situ conventional and satellite-derived observations are assimilated with the main objective of improving Qendresa's model initial conditions and thus its subsequent forecast. The performance of the EnKF system and its impact on the Qendresa forecast are quantitatively assessed using different deterministic and probabilistic verification methods. A discussion in terms of the relevant physical mechanisms adjusted by the EnKF is also provided. Results reveal that the assimilation of both conventional and satellite-derived observations improves the short-range forecasts of the trajectory and intensity of Qendresa. In this context, the relevance of assimilating satellite-derived observations to improve the pre-convective estimation of Qendresa's upper-level dynamics is shown, which is key to obtain a realistic track and intensity forecast of this event.
Seasonal and interannual variability of the landfast ice mass balance between 2009 and 2018 in Prydz Bay, East Antarctica

Published: February 2023

Abstract. Landfast ice (LFI) plays a crucial role for both the climate and the ecosystem of the Antarctic coastal regions. We investigate the snow and LFI mass balance in Prydz Bay using observations from 11 sea ice mass balance buoys (IMBs). The buoys were deployed offshore from the Chinese Zhongshan Station (ZS) and Australian Davis Station (DS), with the measurements covering the ice seasons of 2009–2010, 2013–2016, and 2018. The observed annual maximum ice thickness and snow depth were 1.59 ± 0.17 and 0.11–0.76 m off ZS and 1.64 ± 0.08 and 0.11–0.38 m off DS, respectively. Early in the ice growth season (May–September), the LFI basal growth rate near DS (0.6 ± 0.2 cm d−1) was larger than that around ZS (0.5 ± 0.2 cm d−1). This is attributed to cooler air temperature (AT) and lower oceanic heat flux at that time in the DS region. Air temperature anomalies were more important in regulating the LFI growth rate at that time because of thinner sea ice having a weaker thermal inertia
relative to thick ice in later seasons. Interannual and local spatial variabilities for the seasonality of LFI mass balance identified at ZS are larger than at DS due to local differences in topography and katabatic wind regime. Snow ice contributed up to 27 % of the LFI total ice thickness at the
offshore site close to ground icebergs off ZS because of the substantial
snow accumulation. Offshore from ZS, the supercooled water was observed at
the sites close to the Dålk Glacier from July to October, which reduced
the oceanic heat flux and promoted the LFI growth. During late austral
spring and summer, the increased oceanic heat flux led to a reduction of LFI growth at all investigated sites. The variability of LFI properties across the study domain prevailed at interannual timescales, over any trend during the recent decades. Based on the results derived from this study, we argue that an increased understanding of snow (on LFI) processes, local
atmospheric and oceanic conditions, as well as coastal morphology and
bathymetry, are required to improve the Antarctic LFI modeling.

Authors: McDonald Matthew Tiger , Hayibo Koami Soulemane , Hafting Finn , Pearce Joshua
Published: February 2023

Solar photovoltaic (PV) technology offers a promising means to alleviate environmental and electricity costs challenges for cryptocurrency miners. To analyze this promise, this study investigated the feasibility of using electricity from individually optimized PV systems to power: 1) an individual Bitcoin miner, 2) a DIY intermodal shipping container holding 50 miners, and 3) a commercial mining farm container holding 408 miners. In a controlled lab environment, miners were monitored for electricity use. Then using these values, numerical simulations of both the PV system yield and sensitivity ranges based on the Bitcoin price, Bitcoin halving events, and miner hardware were investigated for informed financial planning. In addition, sensitivity for geographic locations in North America, utility electric rates and PV capital costs were analyzed. The profitability and return on investment (ROI) varied by location primarily because of the geographic distribution of solar flux and utility rates. The ROI for using PV with Bitcoin mining was found to be negative for Toronto and Montreal because of low-cost electricity, while it was 8% for Calgary. In the U.S. cities evaluated, the ROIs were substantial and ranged from 34% in New York, to 64% in Boulder, and up to 104% in Los Angeles. Although the study is based in North America regarding energy rates, climate, and energy laws, the analysis methodology is generalizable globally and grants the average cryptocurrency business the knowledge to make an informed decision on whether to pursue this venture from a financial and environmental perspective. This study contributes to the body of knowledge in cryptocurrency mining by providing an economic means of environmental preservation by powering cryptocurrency miners with renewable solar energy.

Authors: Bonan Giacomo
Published: February 2023

Il Piave è stato cruciale nella storia d’Italia. A lungo via di comunicazione tra le Alpi, Venezia e l’Adriatico, dopo la prima guerra mondiale è stato celebrato come «fiume sacro alla patria» ed è stato l’emblema della modernizzazione del paese attraverso l’industria idroelettrica, le irrigazioni intensive e le bonifiche meccaniche. Oggi è considerato uno dei fiumi più sfruttati e artificializzati d’Europa, ed è conosciuto nel mondo soprattutto per il disastro del Vajont, che l’Unesco ha definito un caso esemplare di ciò che accade quando ingegneri e geologi si rivelano incapaci di cogliere la natura del problema che stanno cercando di affrontare. Attraverso la biografia del fiume, questo libro mette in luce le interdipendenze tra trasformazioni ambientali, culturali e sociali e la loro ridefinizione reciproca nel corso del processo di modernizzazione.

The distinct growth of cardiovascular diseases (CVD) and aortic diseases in the world requires accurate diagnostic methods for their early prediction. In modern research, more and more attention is paid to biomechanics and numerical models of accurate quantitative calculations. The assessment of aortic pathology using magnetic resonance imaging (MRI) acquires great clinical significance, since it makes it possible to simultaneously assess the anatomical topography and physical properties of the aorta. A broad study of changing biomechanical processes will complement the existing ideas about the basics of aneurysm formation and aortic dissection. MRI is a modern non-invasive method that provides the necessary data to as-sess the physical properties of the wall and directional flows in the aorta.

By drawing a nexus between Gloria Anzaldua’s notion of mestiza consciousness and Gayatri Spivak’s conceptualization of speaking subaltern, this article discusses that how the protagonist, Rehana Haque in Tahmima Anam’s A Golden Age raises her voice, struggles for survival and achieves mestiza consciousness in the backdrop of 1971 war and therefore can be named as speaking subaltern in new historicist perspective. Haque is resilient, brave and courageous who not only challenges the societal norms but also sets a precedent for oppressed and marginalized women. She relishes a hope despite hardships to get a country of their own; irrespective of their religion, language and multiple culture. Anam in A Golden Age has brought into limelight the struggle of resilient female figure and the hurdles she faces while achieving mestiza consciousness. The study is qualitative and hence implies concept of Mestiza Consciousness and Subaltern stance. Key Words: Mestiza Consciousness, Speaking Subaltern, 1971 War, New Historicism

Determinants of firm’s decision to produce green products in Dong Nai province
Authors: Hà Nguyễn Minh , Nguyen Nguyen Huu , Quan Le Thai Thuong
Published: February 2023

This study analyzes the determinants of firm’s decisions to produce green products in Dong Nai province. We survey 300 firms which are currently doing business in Dong Nai in 2019. A combination of the propensity score matching (PSM) method and the logit regression addresses the problem of heterogeneity between observations in the empirical model. The result implies that a firm that (i) has assigned a leader to take responsibility for green growth; (ii) has an investment in emission treatment equipment; (iii) has procedure guidance for energy saving; and (iv) has an improvement in energy efficiency will have a higher probability to produce at least a green product. Moreover, a penalty for breaching environmental legislation does not encourage firms to produce green products. Several policy implications have emerged on the ground of our empirical findings. First, we propose cooperation and connection between domestic firms and foreign enterprises to inspire the production of green goods and services. Second, some preferential treatments for firms that assign a manager for green development can encourage green production in Dong Nai province. Finally, Dong Nai province shall consider policies supporting firms to mobilize capital to develop technology for green production.

Intrigue and Feud in Colonial Cyprus: Professor Talbot Rice’s Tendentious Report (1936) on the New Antiquities Department
Authors: Stanley-Price Nicholas
Published: February 2023

In response to criticism about the state of the monuments there, the British government in 1935 set up a Department of Antiquities in its colony of Cyprus. The instability of its first two years owed much to local intrigues and feuds that the colonial governor, Sir Richmond Palmer, failed to resolve. His equivocal stance was tested when, immediately following a visit to the island in 1936, David Talbot Rice, the Watson Gordon Professor of Fine Art at Edinburgh University, submitted to the Colonial Office in London a report criticizing the Department’s work. Dismissed at once by the governor as wildly inaccurate and unhelpful, the report raises questions about Talbot Rice’s possible motives in writing it. The episode reveals the strained nature of metropolis-colony relationships, the fallibility of reports made by visiting experts, and—specifically for the Cyprus case—the governor’s questionable commitment to the new Antiquities Department.
PHYSICOCHEMICAL CHARACTERISTICS AND PROPERTIES OF NANO-MODIFIED COUPLED SMECTITE CATALYSTS WITH AG+/ZN2+
Authors: Kuo Shu-Lung , Ming-Yang Wu Edward
Published: February 2023

This study used smectite clay as a carrier and exchanged Ag+ and Zn2+ onto the smectite via ion exchange. The coupled smectite-Ag/Zn catalysts at the nanolevel were formed after surface modification and high-temperature sintering. Various physicochemical experiments, such as Fourier-transform infrared spectroscopy (FT-IR) analysis, x-ray diffraction (XRD) analysis, transmission electron microscopy (TEM) analysis, and thermal analysis, were conducted to further discuss the physicochemical properties of the smectite-Ag/Zn.

A function group analysis on the modified coupled smectite-Ag/Zn catalysts conducted via an FT-IR spectrum shows that the mineral structures of the catalysts remain intact after high-temperature sintering. In terms of the x-ray analysis, water tends to exist in the layer structure of the smectite, which is affected by humidity in the environment. After being modified by Ag and Zn, shrinkage occurs in layers of the smectite due to water loss. The spacing of layers is thereby narrowed. Moreover, a TEM observation of the coupled smectite-Ag/Zn catalysts after it was sintered at 350oC shows that the sizes of Ag+ and Zn+2 on the smectite-Ag/Zn are between 25-50 nm, respectively. This proves that Ag+ and Zn2+ do exist in the coupled smectite-Ag/Zn catalysts after they were exchanged, and that they are at the nanolevel. As for the thermal analysis, the findings show that significant melting occurs when the coupled smectite-Ag/Zn catalysts are sintered at 459oC, due to the oxidative pyrolysis of micromolecules or solvents.

Published: February 2023

ABSTRACT: The current article analyzes the inextricable and instrumental link between intangible religious heritage and tangible religious heritage. More specifically, UNESCO’s nomination processes are examined in order to investigate the evolution and the approach of national and global institutions to intangible religious heritage. Rituals, architectural techniques of constructions and several UNESCO’s nomination dossiers of religious towns are used to shed a light on problematic aspects. Among them, we should wonder if intangible religious heritage underwent a process of political “instrumentalization”, “scientificization” and “objectivization”: which are the consequences of this institutional activity?

Edge computing is a distributed computing paradigm that involves processing data at or near the edge of the internet of things (IoT) network, instead of centralized server. This makes the cyber-attacks increasingly sophisticated, and traditional security measures become no longer sufficient to protect against them. Concurrently, privacy concerns arise when sensitive data is involved in Edge computing applications containing confidential information. In this paper, we propose a privacy-preserved federated learning (FL) approach for cyber-attack detection in edge based IoT ecosystem. A novel lightweight convolutional Transformer network (LCT) network is designed to precisely identify cyber-attacks though learning attack patterns from IoT traffics in local edge devices, where model is personalized though fine-tuning. The privacy of model and data is preserved in our system via incorporating differential privacy and secure aggregation during the cooperative training process on edge devices. We evaluate our proposed approach on a real-world dataset of network traffic (NSL-KDD) containing various types of attacks, and the experimental results show that our personalized FL approach outperforms traditional FL in terms of detection accuracy. We also show that our approach is effective in handling non-stationary data and adapting to changes in the network environment.

This study aimed to evaluate the ovarian structure, estrus intensity, ultrasound carcass measurements, and pregnancy rate of Nelore breed heifers and cows in accordance with antral follicle counts (AFCs). We evaluated 503 heifers and 565 Nelore cows, with a mean age of 15.5±2.2 and 69.8±36.1 months, respectively, submitted to a fixed-time artificial insemination (FTAI) protocol. On day zero, all bovine females were examined using ultrasound to determine the AFC. The mean AFC of the heifers and cows were 20±8.6 and 22.5±8.4, respectively. The rib-eye area (REA) and fat thickness (FT) of the heifers (n = 119 for REA and n = 219 for FT) were measured using ultrasound imaging. The average conception rates at the first FTAI and at the end of the breeding season were 35.8% and 57.5%, respectively, for heifers and 45.1% and 78.9%, respectively, for cows. We demonstrated that the probability of pregnancy at the first FTAI and at the end of the breeding season for both young heifers and cows increased as the AFC decreased (P>0.001 and P=0.0123, respectively). FT and REA showed no correlation with AFC in heifers. The intensity of estrus expression was negatively correlated with AFC (−0.46; P<0.0001). In conclusion, Nelore heifers and cows with low AFC had a high probability of pregnancy during the entire breeding season. Thus, AFC can be used as a tool to select heifers with increased fertility without affecting carcass traits (REA and FT).

Published: February 2023

The Internet of Things (IoT) is a collection of interconnected intelligent devices that exists within the larger network known as the Internet. With the increasing popularity of IoT devices, massive data is generated day by day. The collected data need to be continuously uploaded to the cloud server. Besides, the transmission of data in the cloud environment is performed via the internet, which faces numerous threats. However, the security issue always lacks an effective big data communication. Therefore, a novel technique called Orthogonal Regressed Steepest Descent Deep Structured Perceptive Neural Learning based Secured Data Communication (ORSDDSPNL-SDC) is introduced with higher accuracy and lesser time consumption. The ORSDDSPNL-SDC technique comprises three phases, namely registration, user authentication, and secure data communication. In the ORSDDSPNL-SDC technique, the registration phase is carried out for creating the new ID, and password for each user in the cloud. The IoT device's data is then sent to a cloud server by the cloud user for storage. After that, the orthogonal regressed steepest descent multilayer deep perceptive neural learning is applied to examine the user_ ID with already registered ID based on Szymkiewicz–Simpson coefficient. Then the Maxout activation function is to classify the user as authorized or unauthorized. Finally, the steepest descent function is applied for minimizing the classification error and increasing the classification accuracy. In this way, the authorized or unauthorized user is identified. Then the secured communication is performed with the authorized cloud users. Experimental evaluation is carried out on the factors such as classification accuracy, classification time and error rate, and space complexity with respect to a number of users. The qualitative results and discussion indicate that the proposed ORSDDSPNL-SDC offers elevated performance with regard to achieving higher classification accuracy and minimum error as well as computation time when compared to the existing methods.
Preoperative biochemical values are correlated with adenoma volume, but not predictive factors for hungry bone syndrome in patients with primary hyperparathyroidism
Authors: Sivgin Hakan , Bostan Mustafa
Published: February 2023

We aimed to investigate correlation between perioperative biochemical values and adenoma volume, the effects of perioperative biochemical values and clinicopathological variables on postoperative hypocalcemia after parathyroidectomy. A retrospective study planned in tertiary university hospital on patients undergone surgery for primer hyperparathyroidism. Preoperative calcium (first, close to surgery, maximum), PTH (first, close to surgery, maximum), alkaline phosphatase (ALP) and phosphorus (P) values, postoperative calcium (early, late), postoperative PTH (early, late), 24-hour urinary calcium calculation, time from the first diagnosis of elevated calcium until surgery, preoperative hypercalcemia treatments, excised parathyroid gland, histopathologic diagnosis, maximum diameter and volume of the excised parathyroid on histopathologic examination, postoperative intravenous calcium supplement were analyzed. 73 patients were included in the study. The median age of the patients was 54 years (range, 18-82), and 83.6% were female. In univariate analysis, patients who were administrated intravenous (IV) calcium supplement had higher preoperative PTH (p=0.024). adenoma volume correlated moderate with preoperative PTH first (r=0.396, p=0.001), preoperative maximum parathormone (r=0.380, p=0.001), preoperative PTH CS (r=0.432, p<0.001) and preoperative first elevated calcium (r=0.240, p=0.041) levels. We conclude that biochemical parameters and adenoma size are not predictive factors in determining the requirement of IV calcium supplement. Preoperative PTH and calcium levels were moderately associated with adenoma volume.

Published: February 2023

This study aimed to investigate the effects of psychodrama on stress and coping with stress in people working as medical doctors and nurses academicians. This study confirmed whether psychodrama could be effective on stress and coping mechanisms for nurses and medical doctors academicians. Individuals were evaluated by the state and continuity anxiety scale, the stress coping style scale, the Hamilton anxiety scale, and the Hamilton depression scale. The Statistical Program for Social Sciences-SPSS for Windows, version 22.0, was used for statistical analysis (SPSS Inc., Chicago, IL, USA).Data are given as mean (standard deviation) and number (percentage). To test the normal distribution compliance of the data, the Kolmogorov Smirnov test, T test for independent groups in normally distributed data with two groups, ANOVA test for data with more than two groups with normal distribution, and Mann Whitney U test for data with normal distribution was used. A statistically significant difference was found in the pre-test and post-test average scores of the applied scales. Practice Implications It is recommended that this study be performed with a more homogeneous patient group. It was found that psychodrama significantly affected stress and stress coping styles in individuals who work as academicians. It was found that psychodrama significantly affected stress and stress-coping styles in individuals. The most important limitation of our study was that the participants were in the same academic community.
A comparison of on-admission blood cell count-derived parameters on the development of contrast-induced nephropathy in acute coronary syndromes
Authors: Celik Casit
Published: February 2023

Contrast-induced nephropathy (CIN) is a clinical entity closely associated with cardiac mortality and morbidity. We aimed to investigate the relationship between CIN after acute coronary syndrome and other bio-inflammatory parameters (Neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, monocyte/lymphocyte ratio) as well as biomarkers such as AST/ALT, SIRI (Systemic Immnun Response Index), AISI (Aggregate Index of Systemic Inflammation), APRI (AST to platelet ratio index), SII (Systemic Immun Inflammation Index) NLR (Neutrophil to lymphocyte ratio), N/LPR (Neutrophil/ (lymphocyte x platelet), PLR (Platelet to lymphocyte ratio), MLR (Monocyte to lymphocyte ratio) and MPVLR (Mean platelet volume to lymphocyte ratio). In this retrospective cross-sectional study, we included 228 patients older than 18 years of age and underwent coronary angiography for acute coronary syndrome between January 2021 and May 2022. We applied the logistic regression analyzes to evaluate the relationship between patients' demographic, clinical characteristics, laboratory parameters, and contrast-induced nephropathy, and to evaluate the predictive power of the AST/ALT, AISI, SIRI, SII, NLR, PLR, MLR, N/LP ratio, MPVLR and other inflammatory based parameters on this primary endpoint. In the univariate analyses, prior history of coronary artery bypass, acute coronary syndrome type, prior ACEi/ARB usage, white blood cell count, hospitalization stay length, contrast amount, MLR, PLR, white blood cell to platelet ratio (WBCPR) were significantly associated with CIN. [p:0.039, p:0.017, p:0.025, p:0.044, p<0.001, p:0.003, p: 0.045, p: 0.044, p:0.044, respectively]. However, multivariable logistic regression analysis showed that WBCPR [OR 0.00 (95% CI 0.00- 0.01) p:0.005] and MLR [OR 13.522 (95% CI 2.15-84.72) p:0.005] might be statistically a significant independent predictor of CIN beside contrast amount [OR 1.92 (95% CI 01.23-3.02) p:0.004]. The WBCPR can be a new valuable independent predictor of CIN. Also, MLR and contrast amount may be a good independent predictor of CIN in acute coronary syndrome.

تأثير اختلاف طريقة التحليل الاحصائي تبعا لنوع البيانات الفترية والرتبية على الخصائص السيكومترية لمقياس ليكرت "دراسة محاكاة"
Authors: زارع د/ نسرين محمد سعيد
Published: February 2023

هدفت الدراسة الحالية إلى الكشف عن تأثير اختلاف طريقة التحليل الإحصائي على الخصائص السيكومترية للمقاييس من نوع ليكرت، حيث تم توليد البيانات عن طريق محاكاة مونت كارلو التي تسمح بالتحكم في خصائص البيانات المولدة لدراسة تأثيرها المباشر على النتائج. ونظرا للطبيعة الرتبية ذات المسافات البينية غير المتساوية لبدائل الاستجابة المتدرجة من نوع ليكرت، يجب معالجتها رياضياً باستخدام الأساليب الإحصائية اللابارامترية. مع ذلك، اعتاد الباحثون على التعامل مع المقاييس من نوع ليكرت كمقاييس فترية ذات مسافات متساوية بين بدائل الاستجابة الخاصة بها. وفي محاولة لفض هذا الاشتباك بين الباحثين، جاءت فكرة هذه الدراسة التي خلصت إلى تأثر الخصائص السيكومترية للمقاييس من نوع ليكرت عند التعامل معها إحصائياً بطريقة تعارض نوعية بياناتها الرتبية، وأوضحت النتائج التحيز النسبي لمعامل ثبات ألفا كرونباخ عند تطبيقه على البيانات الرتبية وذلك لاعتماده الأساسي في حسابه على مصفوفة الارتباط لبيرسون الخاصة بالبيانات المتصلة، بينما كان آداء معامل ألفا الرتبي أفضل بكثير وأعطى صورة أفضل لثبات المقياس بدون تحيز.

    وكذلك تم حساب الصدق البنائي لنموذج البيانات عن طريق استخدام أسلوب التحليل العاملي التوكيدي. ولمعرفة أفضل النماذج أداء ومطابقة للبنية العاملية للبيانات، تمت المقارنة بين النماذج وأعطى النموذج البنائي للبيانات ذات البدائل 11 بديلا للاستجابات أفضل النتائج، وذلك عند استخدام أسلوب التحليل العاملي التوكيدي باستخدام مصفوفة الارتباط متعدد الأقسام Poly-Choric التي تناسب البيانات الرتبية كبديل عن المصفوفة الأساسية للأسلوب والتي تعتمد على معاملات الارتباط لبيرسون، وأوصت الدراسة بتجنب التعامل مع المقاييس من نوع ليكرت على أساس أنها بيانات فترية نظرا لتأثر الخصائص السيكومترية من صدق عاملي وثبات للمقياس جراء هذا التعامل.
