Authors: Qasim Abo AL Hassan , Hasan Ibrahim Naeem , Aljboory Nassif Jassim
Published: August 2022

The problem of recognizing credit losses is one of the most important contemporary problems in accounting thought, as the process of creating a provision for credit losses is one of the most important bases of measurement in hedging against these losses and mitigating their impact. Studies and research in the field of accounting show that the accounting treatment used in accordance with the international standard (IFRS 39) is one of the fundamental reasons for the exacerbation of the global financial crisis in 2008, which is the delay in the recognition of credit losses until they are achieved, which is the so-called model of actual credit losses, as the treatment is based onÂ  recognizing the loss on the actual basis, i.e. after its occurrence, and not on the expected basis, i.e. before it occurs. In light of the criticisms leveled at the international standard (IAS 39) entitled Financial Instruments, the International Accounting Standards Board issued a standard for financial instruments, which is the International Financial Reporting Standard (IFRS 9). The new standard includes a proposed accounting framework for recognizing expected losses. According to the requirements of this standard, banks create provisions to face risks on an expected or estimated basis with the aim of early recognition of credit risks. As a result of the effects that this application will have on credit risks. It was necessary to shed light on the impact of the application of this standard on reducing credit risk, and thus the financial reporting of Iraqi commercial banks will be affected.

Published: August 2022

Cities are in a continuous process with the change and re-adaptation of different parts. Cities are deliberately planned under different socio-economic, natural, religious, and political conditions in different historical periods. While cities are growing, new urban projects are planned that will affect urban morphology. Thus, the research problem is that new urban design projects require planning and integrated policy in interaction with the city. One of the aspects of ensuring this is examining the city from the historical point of view and comprehending urban morphology analysis. Within this framework, the Galata Region is chosen as the study area. The main reason for choosing the study area is; that it is thought the planning of the Galataport Project, the characteristics of the district and its impact should be questioned. Therefore, the study aims to first determine the change and development of the Galata Region over time with the Conzenian approach. In this section, historical maps of the area will be examined through the spatial development of the city, and the determination of the areas affected by the planning decisions will be revealed. Morphological region analysis will be done to identify the focus area boundary. Secondly, the aim is to reveal the impact of the Galataport Project on the region and on the use of the coastline by space syntax method. In this part, the effect of the Galataport Project will be explained comparatively by axiality, convexity, integration and intelligibility, and synergy concept through the 1980 and 2020 maps. As a result, it is seen that the study area has its spatial characteristics, cultural values, and historical process. In the general analysis of the area, it is seen that the old city center is seen as a high potential area for transformation due to its central location. The old city center plays a central role in the marketing of the city because of its economic potential. New design projects are done in the study area because of the transformation potential. It is observed that the Galataport project together with the morphological structure led to functional changes in the field and caused differences in the characteristics of the use of space. It has affected the area and old trading functions began to transform the leisure and tourism sector. Lastly, recommendations are given according to the results.

Authors: Aybar Nesil , Dokmeci Vedia
Published: August 2022

From the 1980s onwards, restructuring of economy and globalization has increased the size and number of companies in Istanbul and demand for modern office space which cannot be provided in the old CBD due to construction restrictions. Thus, multi-center development has started in the city in order to answer to the growing demand for modern office markets. The present study investigated the growth and decline of office rents in office markets which have highest demand and office rents. According to the results of the study, while office rents in the office markets with growth potential have increased, that of the markets with supply increased dramatically between 2011 and 2016. On the other hand, while office rents in all of the office markets were sharply declined in 2021 due to devaluation of Turkish Lira against USD. Although the pandemic has made Work from Home (WFH) and Hybrid working models a global trend, A class office demand stayed strong due to well-being requirements on office area. Thus, it is expected to have a positive impact on the economy of the city.
An experimental study on production opportunities of biocomposite by using fungal mycelium
Authors: Sağlam Sebahat Sevde , Acun Özgünler Seden
Published: August 2022

Due to the adaptability, durability, and affordability of synthetic polymers, their usage has been increasing in the global industry. These petroleum-based polymers remain intact in nature for many years after they expire and cannot be included in the natural recycling network in any way. Producing polymers using fossil resources increasingly day by day threatens existing resources and affects the circular economy negatively. Considering the various negative effects of polymers on the environment, biopolymers could be seen as a strong alternative; which is a polymer group formed by living organisms such as plants, animals, and microorganisms. Ecological, low-emission, and recyclable biopolymers open up new and a broad range of topics in the field. Composite materials created with these biopolymer materials that act as natural adhesives; have different developing areas of applications such as packaging industry, textile, furniture, and industrial design sectors, architectural designs, and structural insulation materials. Fungal mycelium, a biopolymer, consists of fibrous filaments called hyphae, which can be defined as elongated cells, mainly composed of chitin, glucan, and proteins. The ability of fungal mycelium to digest and grow through organic matter makes it possible to produce biocomposites from mycelium. Mycelium-based composites are mixed with fungal mycelium, forming an interpenetrating three-dimensional filamentous network that binds the raw material to the material, and after completing the growth period, the mycelium growth is stopped by heat, thus offering an alternating fabrication paradigm based on the growth of materials.  In this study, firstly, it was tried to find the most efficient ratio among different mixing ratios by using the mycelium of the genus Pleurotus Ostreatus and the same raw materials. Afterward, it was aimed to investigate the mechanical and physical properties through experimental studies, especially the production process, of mycelium-based composites formed by mixing different raw materials in determining proportions.

Published: August 2022

Objectives. This study aimed to estimate the national prevalence of violence against Filipino children and youth as experienced in various forms and settings.

Methods. About 3,866 young people aged 13-24 years from 172 randomly selected barangays (villages) nationwide participated in the survey. The questionnaire was self-administered, interviewer-administered, or interviewer-assisted, depending on the capability and preference of the respondent. Female respondents were interviewed or assisted by a female field assistant, while male field assistants guided the male respondents. The questionnaire was translated into seven local dialects and administered in the most comprehensible language to the respondent.

Results. Overall, 80 percent of the 3,866 respondents experienced any one form of violence in the home, school, workplace, and community. More than 3 in five suffered from physical, psychological, and peer violence, while 22.4 percent were victims of sexual abuse. Ten percent were physically neglected, while a fourth felt psychologically neglected by their caregivers. More boys claimed to have been sexually abused and physically neglected, while more girls were bullied and witnessed psychological violence in the home. VAC prevalence was, however, found to be highest among LGBTQ+s compared to heterosexual males and females. Despite the high prevalence, less than 10 percent of respondents disclosed their experiences of abuse, primarily to friends and parents. About one in 10 ever sought help from a professional.

Conclusion. There is a need to improve the implementation of child protection programs at the local level, where violence issues of heterosexual boys and girls and LGBTs are addressed.

Polyhydroxybutyrate As A Biopolymer
Authors: Priyanka Kumari  , Dr. Madhuri Girdhar
Published: August 2022

This project is about the use of biopolymer (PHB) as an alternative form in place of non-biodegradable plastic, many types of research have been done on this polymer which shows it sharesa similar application as that of conventional plastic and also are biodegradable and biocompatible. As synthetic polymers are cheap and inexpensive but are non-biodegradable and release toxicity that is hazardous for biomass so there is a need to switch on another alternative to reduce the dependence on conventional polymers.
In recent years, the increasing population that resulted in urbanization and industrialization has led to a surge in petroleum-based plastics consumption. Due to its cheap availability and durability, there has been a great demand in every field. The continuous increase in the use of petrochemical plastic is the cause of various environmental pollution as it is non-biodegradable and take thousandof years to break down so produce toxins if it is disposed of in soil and water, even if they burnt that will increase the CO2 concentration in the atmosphere.
There has been neededfor a biopolymer that can compete and reduce the dependency on hazardous plastics. Researchers have been looking for an alternative that would be eco-friendly and sustainable in nature as well as meet the current demand. Polyhydroxybutyrate (PHB) being biocompatible as well as biodegradable can be a better option to switch petroleum-based plastic as it possesses similar physical properties to that of propylene.
PHB is a biopolymer that is a member of the PHA family.PHA are of three types based on the number of monomers present(Madison and Huisman 1999); the short-chain length consists of 3-5 units of carbon, medium chain length consists of 6-14 units of carbon, and the long-chain length consists of more than 15 units of carbon atoms(Anderson and Dawes 1990). The nature of PHB is brittle and crystalline as well as high melting and degradation point due to the presence of double bond that leads to the chemical variation and contrast structure(Colin et al, 2012).To improve its properties we have to blend it with other natural plasticizers such as (glycerol, soybean oil, triethyl citrate, salicylic ester) to reduce its brittleness and improve lowering temperature

The coronavirus disease 2019 (COVID-19) pandemic affected everyone’s life and especially those with chronic conditions, such as diabetes. Therefore, the need for medical care in such populations resulted in identification of new models of health care avoiding physical consultation and reducing the risk of COVID-19 transmission, giving emphasis to telemedicine. There is an increasing amount of studies showing the beneficial impact of the use of telemedicine in patients with type 1 diabetes, while for patients with type 2 diabetes the existing data are limited and conflicting. Therefore, the aim of the present review is to summarize the existing literature data on the impact of telemedicine on the follow-up of patients with diabetes during the pandemic as well as its place in the management of patients with diabetes in the future.
Magnetic resonance imaging of endometriosis: a common but often hidden, missed, and misdiagnosed entity
Authors: Zuber Mohammad , Shoaib Mohammad , Kumari Surbhi
Published: August 2022

Endometriosis is a common benign and chronic inflammatory gynaecological disease due to functional endometrial glands and stroma in an ectopic location outside the uterine cavity. It affects 5-10% of reproductive age group women in the peak age of 24-29 years. However, women with infertility and chronic pelvic pain have an even greater prevalence, accounting for 30-50% and 90% of cases, respectively. Although it is a common entity, patients often get a delayed diagnosis because it is often subtle (hidden), missed, or confused with mimics, leading to misdiagnosis, which significantly affects patients’ quality of life because they live in constant pain from undiagnosed endometriosis. Laparoscopy followed by histopathological confirmation is the gold standard for diagnosis, but it is an invasive procedure. MRI is an excellent non-invasive modality that helps in non-invasive diagnosis, with excellent delineation of the disease extent, and thus provides a presurgical mapping of the disease, which is helpful for the operating surgeon. Radiologists should be aware of all possible spectrum and diagnose this early and provide a detailed structured report mapping the entire extent of the disease process, which helps in effective treatment planning and successful outcomes in improving patients’ quality of life.
An investigation of the efficacy of shear wave elastography
in the characterization of benign and malignant liver lesions
Authors: Keskin Suat , Babaoglu Ozan , Keskin Zeynep
Published: August 2022

Introduction

To investigate whether shear wave elastography (SWE) examination, which has recently been proposed as an accessory radiological examination technique, is effective in characterizing focal liver lesions (FLLs).

Material and methods

A total of 105 patients, comprising 48 males and 57 females, underwent SWE examination. The mean age of the patients was 53.31 ± 1.59 (age range 5-87) years. The SWE measurements were obtained from FLLs that were approximately 2 to 8 cm in depth in a box that was approximately 0.5 × 1 cm wide on an ultrasonography (USG) screen from approximately 2 different locations. Receiver operating characteristic (ROC) curve analysis was performed to determine the diagnostic SWE values in the differentiation of benign and malignant lesions. Sensitivity, specificity, and positive predictive and negative predictive values were calculated in the presence of significant limit values.

Results

The SWE values, in kPa and m/s, in the malignant lesions were significantly higher than those in the benign lesions (p = 0.006, p = 0.011). In the ROC curve analysis, the cut-off value was calculated as 9.005 kPa in the differentiation of malignant lesions from benign lesions. The area under the ROC curve was calculated as 0.656 in the range of 0.551-0.761 with 95% reliability. Sensitivity was calculated as 64.2%, specificity as 61.5%, positive predictive value as 63%, and negative predictive value as 62.7%.

Conclusions

In addition to providing little contribution to the differentiation of benign and malignant lesions, the SWE technique is thought to contribute to a certain extent, especially in suspected cases, during the diagnosis with cross-sectional methods.

Authors: Srirambhatla Annapurna , Hosamani Roopa Devi , Nandury Eshwar Chandra
Published: August 2022

Introduction

Magnetic resonance imaging (MRI) has been used as a problem-solving tool in the diagnosis of adnexal lesions. Both benign and malignant ovarian masses can present as complex adnexal lesions. Preoperative diagnosis of malignancy is essential for planning the surgical approach and appropriate treatment regimen. The aim of our study was to determine the role of diffusion-weighted MRI (DWI) in differentiating benign from malignant adnexal lesions.

Material and methods

Fifty-five patients (constituting 67 lesions) referred to MRI for evaluation of adnexal lesions were studied using 1.5 T MRI. The signal on DWI (qualitative) and ADC values (quantitative DWI) of the solid and cystic components of the lesions were analysed separately. Chi-square test, cross tabulation, and ROC curves were used to determine features on DWI that could distinguish benign from malignant lesions.

Results

Of the 67 lesions, 50 were benign and 17 were malignant. There was a significant association of hyperintense signal of solid components on T2W and DWI with malignancy, with a p-value of 0.003 and 0.001, respectively. Benign lesions showed hypointense signal on T2W and DWI. ADC values of the solid components could not distinguish benign from malignant lesions; p = 0.290. The signal intensity and ADC values of the cystic fluid in benign and malignant lesions showed a significant overlap.

Conclusions

Qualitative DWI acts as an adjunct to conventional MRI in differentiating benign from malignant adnexal lesions showing solid/mixed morphology. It plays no role in distinguishing lesions based on their cystic components. ADC values play no role in differentiating benign from malignant adnexal lesions irrespective of lesion morphology.

Abstract. The methane chemical sink estimated by atmospheric chemistry models (bottom-up method) is significantly larger than estimates based on methyl-chloroform (MCF) inversions (top-down method). The difference is partly attributable to large uncertainties in hydroxyl radical (OH) concentrations simulated by the atmospheric chemistry models used to derive the bottom-up estimates. In this study, we propose a new approach based on OH precursor observations and a chemical box model. This approach improves the 3-dimensional distributions of tropospheric OH radicals obtained from atmospheric chemistry models and reconciles the bottom-up and top-down estimates of the methane sink due to chemical loss. By constraining the model simulated OH precursors with observations, the global tropospheric mean OH concentration ([OH]trop-M) is ~10×105 molec cm−3 (which is 2×105 molec cm−3 lower than the original model-simulated global [OH]trop-M) and agrees with that obtained by the top-down method based on MCF inversions. With the OH constrained by precursor observations, the methane chemical loss is 471–508 Tg yr−1 averaged from 2000 to 2009. The new adjusted estimate is more consistent with the top-down estimates in the recent global methane budget by the Global Carbon Project (GCP) (459–516 Tg yr−1) than the bottom-up estimates using the original model-simulated OH fields (577–612 Tg yr−1). The overestimation of global [OH]trop-M and methane chemical loss simulated by the atmospheric chemistry models is caused primarily by the models’ underestimation of carbon monoxide and total ozone column, and overestimation of nitrogen dioxide. Our results highlight that constraining the model simulated OH fields with available OH precursor observations can help improve the bottom-up estimated methane sink.

Abstract. Ash fall from volcanic eruptions endangers crop production and food security and jeopardises agricultural livelihoods. As population in the vicinity of volcanoes continues to grow, strategies to reduce volcanic risks to and impacts on crops are increasingly needed. This effort involves the use of quantitative relationships for anticipating crop damage from ash exposure. However, current limited models of crop vulnerability to ash rely solely on ash thickness (or loading) and fail to reproduce the complex interplay of other volcanic and non-volcanic factors that drive impact. Amongst these, ash retention on crop leaves affects photosynthesis and is ultimately responsible for widespread damage to crops. In this context, we carried out greenhouse experiments to assess how ash grain size, leaf pubescence and humidity conditions at leaf surfaces influence the retention of ash (defined as the percentage of foliar cover coated with ash) in tomato and chilli pepper plants, two crop types commonly grown in volcanic regions. For a fixed ash mass load (~570 g m-2), we found that ash retention decreases exponentially with increasing grain size and is enhanced when leaves are pubescent (such as in tomato) or their surfaces are wet. Assuming that leaf area index (LAI) diminishes with ash retention in tomato and chilli pepper, we derived a new expression for predicting potential crop yield loss after an ash fall event. A corollary result is that the measurement of crop LAI in ash-affected areas may serve as a useful impact metric. Our study demonstrates that quantitative insights into crop vulnerability can be gained rapidly from controlled experiments, thereby providing a mean to improve models that can predict ash risks to crops accurately. We advocate this approach to broaden our understanding of ash-plant interaction and to validate the use of remote sensing methods for assessing crop damage and recovery at various spatial and time scales after an eruption.
Scenario and Model Dependence of Strategic Solar Climate Intervention in CESM

Abstract. Model dependence in simulated responses to stratospheric aerosol injection (SAI) is a major uncertainty surrounding the potential implementation of this solar climate intervention strategy. We identify large differences in the aerosol mass latitudinal distributions between two recently produced climate model SAI large ensembles, despite using similar climate targets and controller algorithms, with the goal of understanding the drivers of such differences. Using a hierarchy of recently produced simulations, we identify three main contributors including: 1) the rapid adjustment of clouds and rainfall to elevated levels of carbon dioxide, 2) the associated low-frequency dynamical responses in the Atlantic Meridional Overturning Circulation, and 3) the contrasts in future climate forcing scenarios. Each uncertainty is unlikely to be significantly narrowed over the likely timeframe of a potential SAI deployment if a 1.5 C target is to be met. The results thus suggest the need for significant flexibility in climate intervention deployment to account for these large uncertainties in the climate system response.

Abstract. We have examined the most intense external (magnetospheric and ionospheric) and internal (induced) |dH/dt| (amplitude of the 10 s time derivative of the horizontal geomagnetic field) events observed by the high-latitude International Monitor for Auroral Geomagnetic Effects (IMAGE) magnetometers between 1994 and 2018. While the most intense external |dH/dt| events at adjacent stations typically occurred simultaneously, the most intense internal (and total) |dH/dt| events were more scattered in time, most likely due to the complexity of induction in the conducting ground. The most intense external |dH/dt| events occurred during geomagnetic storms, among which the Halloween storm in Oct 2003 featured prominently, and drove intense geomagnetically induced currents (GIC). Events in the prenoon local time sector were associated with sudden commencements (SC) and pulsations, and the most intense |dH/dt| values were driven by abrupt changes in the eastward electrojet due to solar wind dynamic pressure increase or decrease. Events in the premidnight and dawn local time sectors were associated with substorm activity, and the most intense |dH/dt| values were driven by abrupt changes in the westward electrojet, such as weakening and poleward retreat (premidnight) or undulation (dawn). Despite being associated with various event types and occurring at different local time sectors, there were common features among the drivers of most intense external |dH/dt| values: pre-existing intense ionospheric currents (SC events were an exception) that were abruptly modified by sudden changes in the magnetospheric magnetic field configuration. While proper description of the fast changes during SC events appears to require 1 s data, pulsations and substorms may be sufficiently described by 10 s |dH/dt|. 1 min data, however, significantly underestimates the |dH/dt| peaks. Our results contribute towards the ultimate goal of reliable forecasts of dH/dt and GIC.
Canopy structure, topography and weather are equally important drivers of small-scale snow cover dynamics in sub-alpine forests

Abstract. In mountain regions, forests that overlap with seasonal snow mostly reside in complex terrain. Due to persisting major observational challenges in these environments, the combined impact of forest structure and topography on seasonal snow cover dynamics is still poorly understood. Recent advances in forest snow process representation and increasing availability of detailed canopy structure datasets, however, now allow for hyper-resolution (<5 m) snow model simulations capable of resolving tree-scale processes, which can shed light on the complex process interactions that govern forest snow dynamics. We present multi-year simulations at 2 m resolution obtained with FSM2, a mass- and energy-balance based forest snow model specifically developed and validated for meter-scale applications. We simulate a ~3 km2 model domain encompassing forested slopes of a sub-alpine valley in the Eastern Swiss Alps and six snow seasons. Simulations thus span a wide range of canopy structures, terrain characteristics, and meteorological conditions. We analyse spatial and temporal variations in forest snow energy balance partitioning, aiming to quantify and understand the contribution of individual energy exchange processes at different locations and times. Our results suggest that snow cover evolution is equally affected by canopy structure, terrain characteristics and meteorological conditions. We show that the interaction of these three factors can lead to snow distribution and melt patterns that vary between years. We further identify higher snow distribution variability and complexity in slopes that receive solar radiation early in winter. Our process-level insights corroborate and complement existing empirical findings that are largely based on snow distribution datasets only. Hyper-resolution simulations as presented here thus help to better understand how snowpacks and ecohydrological regimes in sub-alpine regions may evolve as a result of forest disturbances and a warming climate. They could further support the development of process-based sub-grid forest snow cover parametrizations or tiling approaches for coarse-resolution modelling applications.

Purpose: The aim of this study was to investigate the effect of different aging methods on repair bond strength of different types of composite resins.
Materials and Methods: Thirty resin composite blocks (5mm×5mm×4mm) were built up with a nanohybrid universal resin composite and a bulk-fill resin composite according to the manufacturer’s instructions, using a silicone matrix. Indirect resin composite blocks were obtained with similar dimensions from prefabricated blocks by microtome. All the samples were air abraded with 50µm aluminum oxide particles. Specimens were then repaired with a nanohybrid resin composite using two step adhesive system. All these specimens were then randomly divided into three groups for aging process (pH cycle, thermal cycle and control group) and tested for shear bond strength. Results were recorded in MPa. Additionally fractured specimens were examined under stereomicroscope to determine the mode of failure. The data was statistically analyzed using two-way ANOVA and Bonferroni correction test (p<0,05).
Results: Statistically significant effect was found on the bond strength values of the aging method and the restorative material (p<0,05). Thermal cycle applied samples showed statistically significantly lower bond strength values than both pH cycle and control group samples (p<0,05). Regardless of the aging method, the overall bond strength of Tetric N-Ceram Bulk Fill is statistically significantly higher than bond strength of Tetric CAD (p<0,05).
Conclusions: Thermal cycle application is an effective aging method and air abrasion has different effects on repair bond strength of the restorative materials according to the content of the materials.
