Authors: Marjanović Boris , Stanimirović Bojan
Published: July 2022

Za postizanje konkurentske prednosti izuzetno je važno prepoznati potrebe potrošača bolje od konkurencije i definirati kriterije vrijednosti koje potrošači primjenjuju pri vrednovanju alternativa. Iz analize u ovome radu pokušalo se identificirati potrebe koje Coca-Cola ispunjava na temelju kriterija obilježja proizvoda i ostalih aktivnosti koje su sistematizirane prema Maslowljevoj hijerarhiji. Utvrđeno je postojanje cijelog niza mogućih potreba. Naime, potrebe se u najmanjoj mjeri klasificiraju u kategoriju fizioloških potreba, što iznenađuje jer napitak ipak služi za zadovoljenje temeljne potrebe gašenja žeđi, a u najvećoj se mjeri odnose na potrebe za samoaktualizacijom. Moguće je zaključiti da kola napitci zadovoljavaju cijeli jedan skup potreba potrošača, a ne samo jednu potrebu.

Published: July 2022

Ljudi se svakodnevno susreću s donošenjem raznih financijskih odluka kao što su krediti, štednja, i osiguranja. Ako su takve financijske odluke pogrešno donesene, one mogu imati utjecaj na samu kvalitetu života pojedinca i ostatka obitelji. Stoga, da bi se uspješno upravljalo vlastitim financijama potrebno je financijski opismenjavati sve skupine građana u Republici Hrvatskoj kako bi stekli financijske kompetencije koje su danas postale nužne za život. Provjera financijske pismenosti sastoji se od provjere stupnja informiranosti, financijskog ponašanja, stavova i uvjerenja te konkretnog financijskog znanja. S obzirom da je vlada Republike Hrvatske 2015.godine ustanovila nisku razinu financijske pismenosti građana u usporedbi sa ostalim članicama EU, ukazala se potreba za provođenjem projekta financijskog opismenjavanja koji je trajao od 2015. do 2020. godine te se očekuje i daljnja provedba u periodu od 2021. do 2026.godine. Ako financijsko opismenjavanje promatramo kao projekt, važno je utvrditi pojedine grupe procesa koje su se provodile, kako bi se mogla ustanoviti njegova učinkovitost. Na tom tragu, ovaj rad sadrži teorijsku osnovu upravljanja projektima i grupama procesa projekta koja služi za bolje razumijevanje i analiziranje provedenog projekta financijskog opismenjavanja u Republici Hrvatskoj, a sve s ciljem dobivanja uvida o mogućim preporukama za unaprjeđenje budućih projekata financijskog opismenjavanja.
Lea Koenig and Miriam Zohar: Theater Actresses as Memory Agents
Authors: Horovitz Roy
Published: July 2022

The art of theater takes place, as a rule, in the ‘here and now’ of the present, yet all participants in a theatrical production (first and foremost the actors) contribute their personal and professional ‘past’ to this ‘present.’ Both ‘first ladies’ of Israeli theater, Lea Koenig and Miriam Zohar, are Holocaust survivors and ninety years old. Throughout rich careers which span over seven decades, Lea Koenig and Miriam Zohar have been cast in ‘Holocaust Plays.’ This essay examines the way they incorporated personal biography in their theatrical performances and their interpretations of dramatic texts. An examination of the different projects in which they were involved reveals that each of them made use of a different strategy to address the memory of the Holocaust in Israel. Their personal cases can both teach us about the role of the artist as an agent of memory within the society in which he or she lives and performs and exemplify more general patterns in Israel’s memory of the Holocaust.

Abstract. The Arctic Ocean is continuously warming, resulting in sea ice retreat, which significantly impacts the marine biogenic sulfur cycle. The formation of aerosols from DMS oxidation and their climatic effects in the polar regions are of great concern. However, the impact of DMS chemistry on atmospheric aerosols in the high Arctic Ocean (AO) is still unclear due to the limitation of field observations and datasets. Gaseous methanesulfonic acid (MSA) and aerosol chemical species (MSA, SO42- and DMA, etc.) were determined simultaneously with a high time resolution (1 hour) in the AO and Pacific Ocean (PO) to reveal the DMS chemistry in these regions. Extremely low MSA concentrations were observed in the high AO (75°–85° N), with an average of only 7.42 ± 6.60 ng•m-3. However, high MSA concentrations, with an average of 168.60 ± 167.60 ng•m-3 were observed in the mid-latitude regions (45°–60° N). Sea salt aerosols were the most dominant source in the high Arctic Ocean, accounting for 88.78 % of the total aerosols, which was much larger than the values in the other regions. The MSA fraction was much lower in the high latitude regions than in the other regions, accounting for only 1.61 % of the total aerosol particles. The latitudinal distribution of MSA was consistent with that of DMS over the AO. Low DMS chemistry was determined based on the low DMS emissions in the HL region. These results highlight the contribution of DMS chemistry to atmospheric aerosols and extend the knowledge of how biogenic aerosols impact the regional atmosphere in the high AO.

Abstract. The light-absorbing organic aerosol (OA), known as brown carbon (BrC), has important radiative impacts, however its sources and evolution after emission remain to be elucidated. In this study, the light absorption at multiple wavelengths, mass spectra of OA and microphysical properties of black carbon (BC) were characterized at a typical sub-urban environment in Beijing. The absorption of BC is constrained by its size distribution and mixing state, being subtracted from total absorption to obtain the absorption of BrC, then by applying the least-correlation of BC absorption with secondary BrC, the absorption contributed by BC, primary BrC and secondary BrC was apportioned. The multi-linear regression analysis on the factorized OA mass spectra indicated the OA from traffic and biomass burning emission contributed to primary BrC. Importantly, the moderately oxygenated OA (O/C=0.62) was revealed to highly correlate with secondary BrC. These OA had higher nitrogen content, in line with the nitrogen-containing functional groups detected by the Fourier transform infrared spectrometer. The photooxidation was found to result in reduced contribution of primary BrC about 20 % but enhanced contribution of secondary BrC by 30 %, implying the concurrent whitening and darkening of BrC. This provides field evidence that the photochemically produced secondary nitrogen-containing OA can considerably compensate some bleaching effect on the primary BrC, hereby causing radiative impacts.

Abstract. After the decrease of ozone-depleting substances (ODSs) as a consequence of the Montreal Protocol, it is still challenging to detect a recovery in the total column amount of ozone (total ozone) at northern high-latitudes. To assess regional total ozone changes in the "ozone-recovery"-period (2000–2020) at northern high-latitudes, this study investigates trends from ground-based total ozone measurements at three stations in Norway (Oslo, Andøya, and Ny-Ålesund). For this purpose, we combine measurements from Brewer spectrophotometers, ground-based UV filter radiometers (GUVs), and a SAOZ instrument. The Brewer measurements have been extended to work under cloudy conditions using the global irradiance (GI) technique, which is also presented in this study. We derive trends from the combined ground-based time series with the multiple linear regression model from the Long-term Ozone Trends and Uncertainties in the Stratosphere (LOTUS) project. We evaluate various predictors in the regression model and found that tropopause pressure and lower-stratospheric temperature contribute most to ozone variability at the three stations. We report significant positive trends at Andøya (0.9 % per decade) and Ny-Ålesund (1.5 % per decade) and no annual trends at Oslo, but significant positive trends in autumn at all stations. Finally we found positive but insignificant trends of around 3 % per decade in March at all three stations, which may be an indication for Arctic spring-time ozone recovery. Our results contribute to a better understanding of regional total ozone trends at northern high-latitudes, which is essential to assess how Arctic ozone responds to changes in ODSs and to climate change.

Abstract. Biomass burning emissions often contain brown carbon (BrC), which
represents a large family of light-absorbing organics that are chemically
complex, thus making it difficult to estimate their absorption of incoming
solar radiation, resulting in large uncertainties in the estimation of the
global direct radiative effect of aerosols. Here we investigate the
contribution of BrC to the total light absorption of biomass burning
aerosols over the South-East Atlantic Ocean with different optical models,
utilizing a suite of airborne measurements from the ORACLES 2018 campaign.
An effective refractive index of black carbon (BC),
meBC=1.95+ikeBC, that characterizes the absorptivity of all
absorbing components at 660 nm wavelength was introduced to facilitate the
attribution of absorption at shorter wavelengths, i.e. 470 nm. Most values
of the imaginary part of the effective refractive index, keBC, were
larger than those commonly used for BC from biomass burning emissions,
suggesting contributions from absorbers besides BC at 660 nm. The TEM-EDX
single-particle analysis further suggests that these long-wavelength
absorbers might include iron oxides, as iron is found to be present only
when large values of keBC are derived. Using this effective BC
refractive index, we find that the contribution of BrC to the total
absorption at 470 nm (RBrC,470) ranges from ∼8 %–22 %,
with the organic aerosol mass absorption coefficient (MACOA,470) at
this wavelength ranging from 0.30±0.27 to 0.68±0.08 m2 g−1. The core–shell model yielded much higher estimates
of MACOA,470 and RBrC,470 than homogeneous mixing models,
underscoring the importance of model treatment. Absorption attribution using
the Bruggeman mixing Mie model suggests a minor BrC contribution of 4 %
at 530 nm, while its removal would triple the BrC contribution to the total
absorption at 470 nm obtained using the AAE (absorption Ångström
exponent) attribution method. Thus, it is recommended that the application
of any optical properties-based attribution method use absorption
coefficients at the longest possible wavelength to minimize the influence of
BrC and to account for potential contributions from other absorbing
materials.
Numerical Modeling Investigation of Flushing Characteristics and Water Age in a Highly Stratified estuary: Mobile Bay, Alabama, U.S.A.
Authors: Savant Gaurav , McAlpin Tate O.
Published: July 2022

Abstract. The knowledge of timescales of flushing processes within an estuary is essential for the health, and productivity of the estuary, as well as for optimum estuarine management. The hydrodynamics, flushing times, and freshwater age within Mobile Bay were investigated using a three-dimensional (3D) numerical model, Adaptive Hydraulics. Bay flushing and freshwater times were analyzed for various freshwater flow conditions, wind conditions and investigated the influence of the Coriolis force. The flushing times were directly related to the magnitude of freshwater inputs to the system, with the bay exhibiting an average flushing time of 16.5 days for average river inflows. Freshwater age in the bay was closely associated with the freshwater inflows as well as with location in the Bay and varied from 2 days in the Upper Bay to 21 days in the Lower Bay for average river inflows. Northerly, Easterly, and Westerly winds play an enabling role in the flushing process, with lower depth-averaged flushing times compared to those without winds, with Northerly and Easterly winds being the most efficient. Southerly winds increase flushing times by changing the circulation patterns in the Bay.

Published: July 2022

Abstract. Climate projections from global circulation models (GCMs) part of the Coupled Model Intercomparison Project 6 (CMIP6) are often employed to study the impact of future climate on ecosystems. However, especially at regional scales, climate projections display large biases in key forcing variables such as temperature and precipitation, which hamper predictive capacity. In this study we examine different methods to constrain regional projections of the carbon cycle in Australia. We employ a dynamic global vegetation model (LPJ-GUESS) and force it with raw output from CMIP6 to assess the uncertainty associated with the choice of climate forcing. We then test different methods to either bias correct or calculate ensemble averages over the original forcing data to constrain the uncertainty in the regional projection of the Australian carbon cycle. We find that all bias correction methods reduce the bias of continental averages of steady-state carbon variables. Carbon pools are insensitive to the type of bias correction method applied for both individual GCMs and the arithmetic ensemble average across all corrected models. None of the bias correction methods consistently improve the change in carbon over time, highlighting the need to account for temporal properties in correction or ensemble averaging methods. Some bias correction methods reduce the ensemble uncertainty more than others. The vegetation distribution can depend on the bias correction method used. We further find that both the weighted ensemble averaging and random forest approach reduce the bias in total ecosystem carbon to almost zero, clearly outperforming the arithmetic ensemble averaging method. The random forest approach also produces the results closest to the target dataset for the change in the total carbon pool, seasonal carbon fluxes, emphasizing that machine learning approaches are promising tools for future studies.
Water isotopic imprints of Pacific Walker Circulation responses to CO2 decline during the late Pliocene and early Pleistocene
Authors: Mayer Theodor , Feng Ran , Bhattacharya Tripti , McClymont Erin , Ford Heather , Ling Ho Sze
Published: July 2022

Ocean-atmosphere coupled models predict pronounced weakening of the Pacific Walker Circulation (PWC) with increasing CO2 concentration associated with the enhanced tropospheric stability and reduced convective mass overturning. However, instrumental observations from the past few decades are inconsistent and do not support a clear weakening of the Walker circulation. The detection of the role of increasing CO2 is in part impeded by substantial internal variability and anthropogenic aerosol forcings. Here we explore the possibility of using a paleoclimatic analogue to understand the contemporary PWC sensitivity to CO2 changes. We focus on the interval from mid-Piacenzian (MP, 3.3 – 3.0 Ma) to early Pleistocene (~2.4 Ma). The MP had elevated CO2 concentrations (~400ppm) and geography, topology, and vegetation similar to today. Following the MP, global CO2 and temperature decreased, leading to the intensification of the Northern hemisphere glaciation. We seek to identify potential proxy constraints on model simulated PWC sensitivity to CO2 forcing by focusing on changes in the hydroclimatology during this time interval. We developed several sets of isotope-tracking enabled CESM version 1.2 simulations, which utilize pre-Industrial and mid-Piacenzian boundary conditions, different CO2 levels, and water tagging of several key oceanographic regions to track the life cycles of various water species (H216O, H218O and HD16O). Preliminary results show that Pliocene boundary conditions have little impact on the relationship between the CO2 forcing and the intensity of PWC. The precipitation δD contrast between the eastern and western tropical Pacific is linked to varying rates of moisture convergence change, and scales well with the PWC strength, suggesting high potential for developing PWC strengths proxy with precipitation isotopic records from both sides of the tropical Pacific. Our ongoing work will further identify physical processes responsible for the simulated precipitation isotopic signals: i.e., whether they reflect changes in the moisture source, moisture transport, or moist convection at the destination. Furthermore, coupled simulations are being carried out to understand seawater isotopic signatures of PWC related precipitation changes, and contributions from changing ocean dynamics to PWC changes during this interval.

Abstract. Ice core records from Law Dome in East Antarctica collected over the last four decades provide high-resolution data for studies of the climate of Antarctica, Australia, and the Southern and Indo-Pacific oceans. Here, we present a set of annually dated records of trace chemistry, stable water isotopes and snow accumulation from Law Dome covering the period from −11 to 2017 CE (1961 to −66 BP 1950) and the level-1 chemistry data from which the annual chemistry records are derived.
Law Dome ice core records have been used extensively in studies of the past climate of the Southern Hemisphere and in large-scale data syntheses and reconstructions in a region where few records exist, especially at high temporal resolution. This dataset provides an update and extensions both forward and back in time of previously published subsets of the data, bringing them together into a coherent set with improved dating to enable continued use of this record.

Increased vertical resolution in the stratosphere reveals role of gravity waves after sudden stratospheric warmings
Authors: Wicker Wolfgang , Polichtchouk Inna , Domeisen Daniela I. V.
Published: July 2022

Abstract. Sudden stratospheric warmings (SSW) have a long-lasting effect within the stratosphere as well as impacts on the underlying troposphere. However, sub-seasonal forecasts of the winter polar stratosphere fail to use their full potential for predictability as they tend to underestimate the magnitude and persistence of these events already within the stratosphere. The origin of this underestimation is unknown. Here, we demonstrate that the state-dependent stratospheric cold bias following SSW events in sub-seasonal hindcasts can be halved by increasing vertical model resolution, suggesting a potential sensitivity to gravity wave forcing. While the predictability of the planetary Rossby wave flux into the stratosphere at lead times longer than a week is limited, the existence of a critical layer for gravity waves with a small zonal phase speed caused by the disturbed polar vortex provides predictability to the upper stratosphere. Gravity wave breaking near that critical layer can, therefore, decelerate the zonal flow consistently with anomalous subsidence over the polar cap leading to warmer temperatures in the middle polar stratosphere. Since the spectrum of gravity waves involves vertical wavelengths of less than 4000 m, as estimated by wavelet analysis, a high vertical model resolution is needed to resolve the positive feedback between gravity wave forcing and the state of the polar vortex. Specifically, we find that at a spectral resolution of TCo639 (approximate horizontal grid-spacing of 18 km) at least 198 levels are needed to correctly resolve the spectrum of gravity waves in the ECMWF Integrated Forecasting System. Increasing vertical resolution in operational forecasts will help to mitigate stratospheric temperature biases and improve sub-seasonal predictions of the stratospheric polar vortex.

Published: July 2022

Abstract. This work presents
a high-fidelity shape optimization framework based on computational fluid dynamics (CFD).
The presented work is the first comprehensive
curved tip shape
study of a wind turbine rotor to date using a direct CFD-based approach.
Preceding the study is a thorough literature survey particularly focused on wind turbine blade tips in order to place the present work in its context.
Then follows a comprehensive analysis to quantify mesh dependency and to present needed mesh modifications ensuring a deep convergence of the flow field at each design iteration. The presented modifications allow the framework to produce up to six-digit-accurate finite difference gradients
which are verified using
the
machine-accurate Complex-Step method.
The accurate gradients result in a
tightly
converged design optimization problem
in which the studied
problem
is to maximize power using 12
design variables while satisfying constraints on geometry, as well as on the bending moment at 90 % blade length. The optimized shape has about 1 % r/R blade extension, 2 % r/R flapwise displacement, and slightly below 2 % r/R edgewise displacement
resulting in a 1.12 % increase in power.
Importantly, the inboard part of the tip is de-loaded using twist and chord design variables as the blade is extended, ensuring that the baseline steady-state loads are not exceeded.
For both analysis and optimization an industrial-scale mesh resolution of above 14×106 cells is used, which underlines the maturity of the framework.

Published: July 2022

Cancer therapeutics have evolved more significantly during the last two decades with increasing focus on precision medicine. In principle this involves targeted therapies tailored to patients’ cancer-specific molecular attributes. It includes a repertoire of immunomodulating, and apoptotic agents added to cytotoxic chemotherapy, to increase effectiveness. Tumor Associated Macrophages (TAMs) are an interesting potential targets for expanding these therapies. These represent a spectrum of subtypes with anti-inflammatory M1 and pro-tumor M2 being the predominant among all. A large number of studies have established their central role in modulating the tumor microenvironment (TME) and contributing to tumor initiation, and progression. Potential therapeutic strategies that modulate TAMs reduce or block monocyte recruitment, induce apoptosis of TAMs, re-educate TAMs from pro-tumor M2 to anti-tumor M1, among others. This review takes a detailed look at this evolving landscape

Published: July 2022

Objectives: There is rising world-wide burden of chronic kidney disease (CKD) with high Cardio-vascular mortality. This research aims to study echocardiography based cardiac function with respect to CKD stages. Study Design and Setting: This cross-sectional study was conducted at RIHS Islamabad (Jan 2021–Jan 2022) after ethical approval. Methodology: Total 130 adult CKD cases were included by consecutive sampling. Acute kidney injury and diagnosed/treated cases of cardiac disease were excluded. BMI and GFR was calculated. CKD staging done by KDOQI-classification. Cardiac impairment categorized by ECG and Echocardiography. Data analyzed by SPSS V-22 with Chi-square test. Results: Amongst 130 CKD cases, there were 66(51%) males and 64(49%) females. Mean age was 60+13.27 years, mean BMI was 24+4.2. Diabetes mellitus was observed in 100(76.9%), hypertension in 122(93.8%). Mean creatinine was 4.83mg/dl and mean GFR was 17.84 mL/min/1.73m2. Twenty-five(19.2%) patients were on hemodialysis. Mean cardiac EF was 49.18%. EF was normal in 39(30%), mildly reduced in 40(30.8%), moderately reduced in 29(22.3%) and severely reduced in 22(16.9%), diastolic dysfunction seen in 08(6.2%). Twenty-five(18.5%) cases had congestive cardiac failure; 14(56%) compensated and 11(44%) decompensated CCF. There was significant association between GFR and EF (p<0.0001). Conclusions: Decline in cardiac function is associated with advanced CKD stages. Cardiac evaluation suggested at initial presentation of CKD, hence diagnosing asymptomatic compensated heart failure. Study finds high burden of diabetes, hypertension, anemia and IHD in CKD cases. GFR should be used rather than isolated creatinine in CKD. High clinical suspicion and early intervention may lead to better outcome.

Published: July 2022

Pressure vessel is a container for a fluid, both liquid fluid and pressurized gas. In designing a pressure vessel, there are several things that must be considered, namely the stress that appears on the vessel wall due to the pressure caused by the fluid in the vessel, the weight of the vessel itself, or due to pressure arising from external factors. The process of making pressure vessels is carried out using the rolling process and the assembly welding process. The welding process must be considered based on the level of density, leakage and at the same strength. Planning the welding procedure to be carried out on the pressure vessel, the first welding process carried out is Head, Shell 1 body, Shell 2 Body, Shell 3 cone, Shell 4 cone, and Bottom Plate. The material to be used is SA 516 GR 70 according to ASME (American Society of Mechanical Engineers) section II D. Welding process using GMAW (Gas Metal Arc Welding), welding connection planning, welding parameters and everything related to the welding process is determined and summarized on WPS (Welding Procedure Specification) based on ASME (American Society of Mechanical Engineers) section IX. Testing on the welding results is carried out in several stages starting from the penetrant test, radiography test, peneumatic test, and hydrostatic test. The test is carried out to determine the quality of the welding results. Then an analysis of the results of the welding that has been tested is carried out to really know the quality of the standardization used. Based on the results of several stages of testing on the GMAW (Gas Metal Arc Welding) welding process with the standardization used, there are still defects in the welding results.

It is imperative to explore the stability of the money demand function (MDF) due to its effectiveness in the strength of monetary policy. This paper employs the ARDL approach to examine whether the M3 MDF is stable for the Gulf Cooperation Council (GCC) consisting of six Arabian Gulf countries. The paper also uses CUSUMSQ and CUSUM tests for this purpose. Unit root test results indicate that variables have unit roots with varying degrees. The results reveal that M3 has a cointegration relation with inflation and real output, however, the interest rate is statistically insignificant for most countries across the period under study. However, the CUSUM and CUSUMSQ tests indicate that M3 MDF is unstable across all the GCC countries. It implies that the governments in GCC countries have to be very careful in implementing monetary policy to achieve stability and growth targets.

Published: July 2022

Anatomy is a secular science that had contributions from great anatomists, mainly doctors. In the 16th century, modern anatomy emerged, and the studies of the physician and anatomist Andreas Vesalius, "father of modern anatomy", corrected the errors of his predecessors through human dissection and revolutionized the writing of anatomy with his work. Almost 200 years later, Marie François Xavier Bichat is "father of histology", contributed significantly to the description of tissues, expanding the studies of macroscopic anatomy to microscopic. In this article, the authors revisit the findings of anatomists notorious and their significant preliminary contributions to the current planning of surgical interventions.
