ObjectiveTo investigate the histological and biochemical alterations in the pancreas associated with statin-induced toxicity using a rat model.
MethodologyA one-year laboratory-based experimental control trial conducted at department of anatomy of a public sector medical college in Rawalpindi, in collaboration with the National Institute of Health (NIH) Islamabad and Armed Forces Institute of Pathology (AFIP) Rawalpindi. Twenty male Sprague-Dawley rats were assigned to the control group and another twenty to the experimental group. For a duration of 12 weeks, the experimental group was given 60 mg/kg/day of simvastatin orally, whereas the control group was given water and a conventional diet. The following characteristics were measured: body weight, pancreatic weight, biochemical parameters (cytokines, enzymes), and histological alterations (congestion, necrosis, fibrosis). Version 23 of the Statistical Package for the Social Sciences (SPSS) program was used to analyze the data. Qualitative variables were expressed as percentages and frequencies. The statistical significance was defined as P < 0.05. Chi-square analyses contrasted the qualitative factors among the groups.
ResultsCompared to controls, the simvastatin group showed significantly increased mean pancreatic weight (p=0.043), congestion (55% vs 0%, p<0.001), higher levels of CRP (p<0.030), IL-6 (p<0.040), and TNF-α (p<0.040). Trends of mild necrosis (25% vs 5%, p=0.182) and interstitial fibrosis (15% vs 0%, p=0.231) were observed but not statistically significant.
DiscussionThis work shows that simvastatin significantly affects the pancreatic histomorphology and biochemical parameters in rats. It causes a noticeable amount of necrosis, interstitial fibrosis, and changes the pancreatic biochemical profile. These changes raise the possibility of long-term statin-associated pancreatitis and endocrine/exocrine dysfunction. Using a stable animal model, these new findings offer distinctive insights into the impact of simvastatin on pancreatic morphology.
Conclusion
Simvastatin profoundly impacts pancreatic histomorphology, warranting further investigation into mechanisms of toxicity and close monitoring of patients for pancreatic adverse effects during statin therapy.
ENGLISH MEDIUM INSTRUCTION IN THE CONTEXT OF INTERNATIONALISATION OF UNIVERSITIES IN KAZAKHSTAN: A SYSTEMATIC REVIEW OF LITERATURE
Authors: Gaipov D. , Kozhakhmet S. , Kassymova G. , Tulepova S.
Published: August 2024

This paper undertakes a comprehensive review of the existing literature concerning English-medium instruction (EMI) within Higher Education Institutions in Kazakhstan. EMI is a fast growing global phenomenon pushed by the internationalisation of higher education in pursuit of building a competitive, highly qualified human capital. An upward trend is observed in the number of universities incorporating English-medium programs, with 44 universities currently facilitating special EMI groups. In order to explore the research on EMI, scientific literature from featured electronic databases was searched by inserting the relevant key words. Our research discloses that a preponderance of studies examining EMI in Kazakhstan focuses on graduate programs, leaving undergraduate-level EMI relatively unexplored. Moreover, the provision of quality assurance for EMI, an essential element that incorporates the needs of all stakeholders, is a considerably under-studied area. The scarcity of knowledge in this area lends urgency and relevance to our research.

Published: August 2024

Abstract. Using spaceborne lidar and radar observations, this study identifies deep convection systems (DCSs), including deep convection cores (DCCs) and anvils, over the Tibetan Plateau (TP) and tropical Indian Ocean (TO) and finds that DCSs over the TP are less frequent, exhibiting narrower and thinner DCCs and anvils compared to those over the TO. The thinner DCCs over the TP exert weaker radiative cooling effects at the top of atmosphere (TOA) compared to the TO. But, the shortwave TOA cloud radiative effect (CRE) of TP anvils is stronger than that of the TO possibly due to more densely packed cloud tops over the TP. It results in a stronger TOA CRE of DCSs over the TP than that of TO. In particular, the longwave CRE of DCSs over the TP is notably greater at surface and low-level atmosphere due to the distinct lower temperature and less water vapour. The width of DCSs shows a positive correlation with wind shear and atmospheric instability, and the underlying mechanisms are discussed. We also find that the impact of aerosols on cloud top heights and precipitation displays significant discrepancies between the two regions. It is because that the aerosol invigoration effect is less efficient on the TP DCSs, mainly attributed to the significantly colder cloud base. Due to competition between invigoration and direct/semi-direct radiative effects of aerosols, the correlation between precipitation and aerosols over the TP is not obvious. However, precipitation in the TO experiences invigoration followed by suppression with increasing aerosols, due to the dominance of aerosol radiative effects and enhancement entrainment under polluted conditions.
The role of petrophysics in interpreting geophysical images: the effect of rock chemistry and texture on seismic velocities
Authors: Sonnet Manon , Labrousse Loïc , Bascou Jérôme , Fortin Jérôme , Motra Hem
Published: August 2024

The diversity and resolution of current geophysical models in the Alps make it possible to interpret changes in rock properties in terms of deformation or metamorphic reactions.However, there are only a small number of rocks for which the seismic properties at different PT are known, and eclogitisation is the only metamorphic reaction whose effect on the seismic velocities of rocks is known. Yet there are other metamorphic reactions that can modify seismic velocities, particularly those involving micas and amphiboles. For example, by studying the effect of rock chemistry on seismic velocities using field analogues from the European lower crust, we show that amphibole-to-granulite transformation is a strong alternative to eclogitisation in the European lower crust. On the other hand, by modifying velocity contrasts according to wave propagation directions, rock anisotropy is likely to produce or erase some conversions in receiver function models, depending on the seismic events considered. In order to constrain interpretations, a better understanding of the evolution of rock anisotropy as a function of P and T is therefore required, as well as the way this property is transferred to the higher scale, i.e. seismic. Within a sample, the bedding, the shape of the anisotropic minerals and the presence of cracks (shape, orientation and filling) are factors that greatly influence the anisotropy of rocks. By comparing the results of direct measurements on a macroscopic scale with those calculated from crystallographic measurements on a thin-section scale, we show that bedding increases anisotropy on a larger scale and discuss the effects of the shape of crystals or cracks.
Mantle rheology inferred from seismic tomography and foreland basin uplift around the Alps-Carpathian arc
Authors: Handy Mark R.
Published: August 2024

Positive P-wave velocity Vp anomalies beneath the Alps resolved with teleseismic tomography (TEL, Paffrath et al. 2021) and local earthqake tomography (LET, Jozi Najafabadi et al. 2022) from AlpArray have geometries that are reminiscent of drips rather than slabs. These slab drips are still attached to the European orogenic lithosphere in the Central Alps, but appear to be partly detached in the Eastern Alps (Handy et al. 2021). The amount of Neogene crustal shortening during north-directed Adriatic indentation of the latter corresponds to the length of the slab drip within the limits of vertical resolution (20-50 km) down to a depth of 300 km (McPhee & Handy, in press). This allows us to establish the ages of the drip (14-21 Ma) and of a horizontal negative Vp-anomaly (≤ 14 Ma) separating this drip from its orogenic lithosphere.Using these ages, we estimate the sink rate of the hanging part of the European slab drip to be 6-11 mm/yr. A higher sink rate (32 mm/yr) is obtained by using the clockwise migration of depocenter uplift and thrusting in the foreland basin around the Carpathian arc as proxies for the timing of slab detachment from the European orogenic lithosphere (Meulenkamp et al. 1996). Accordingly, the slab drip detached between 19 and 11.5 Ma and is currently entrained in the Mantle Transition Zone, MTZ (Wortel & Spakman 2000). Taken together, these relations indicate that the sink rate of slab drips increased with depth and time. However, we are unable to ascertain whether these drips reached a terminal sink velocity.The lack of Neogene magmatism in the Alpine orogen suggests that detachment and sinking of the slab drips occurred in the absence of melting of the mantle. Taking the sink rates above at face value, we apply a modified form of the Stoke’s Law equation to obtain a dynamic viscosity of some 108 MPa-s for asthenosphere undergoing solid-state flow around the slab dripping beneath the Eastern Alps. This is several orders of magnitude greater than the generally cited range of asthenospheric viscosities in subduction settings (1012 – 1013 MPa-s) as well as viscosities obtained for polycrystalline dunite undergoing grainsize-insensitive creep (1011-1013 MPa-s, grainsize = 1cm), but similar to viscosities for grainsize-sensitive creep (109 MPa-s, grainsize = 50 microns, Handy et al. 1989) in the temperature range (1270-1345 °C) of the aforementioned negative Vp-anomaly (≤ 14 Ma) under the Eastern Alps. While we can only speculate on the temperatures and syntectonic grainsize in the asthenospheric mantle beneath the Alps, our findings indicate that suborogenic asthenophere is anomolously weak, even in the absence of melting, and facilitates the rapid detachment and sinking of slabs at the end of convergence and indentation.
The long-lasting exhumation history of the Ötztal-Stubai Complex (Eastern European Alps): New constraints from zircon (U-Th)/He age-elevation profiles and thermo-kinematic modeling
Authors: Wolff Reinhard , Hölzer Kyra , Hetzel Ralf , Dunkl István
Published: August 2024

The Eastern European Alps formed during two orogenic cycles, which took place in the Cretaceous and Cenozoic, respectively. In the Ötztal-Stubai Complex – a thrust sheet of Variscan basement and Permo-Mesozoic cover rocks – the record of the first (Eoalpine) orogeny is well preserved, because during the second (Alpine) orogeny the complex remained largely undeformed. We use new zircon (U-Th)/He (ZHe) ages and thermo-kinematic modeling to constrain the cooling and exhumation history of the central part of the Ötztal-Stubai Complex since the Late Cretaceous. The ZHe ages from two elevation profiles increase over a vertical distance of 1500 m from 56±3 to 69±3 Ma (Stubaital) and from 50±2 to 71±4 Ma (Kaunertal), respectively (Hölzer et al., accepted by Lithosphere). These ZHe ages and few published zircon and apatite fission track ages were used for inverse thermo-kinematic modeling. The modeling results show that the age data are well reproduced with a three-phase exhumation history. A first phase with relatively fast exhumation (~250 m/Myr) during the Late Cretaceous ended at ~70 Ma and is interpreted to reflect the erosion of the Eoalpine mountain belt. As Late Cretaceous normal faults occur at the margins of the Ötztal-Stubai Complex, normal faulting may have also contributed to the exhumation of the study area. Subsequently, a long period with slow exhumation (
Estimating lateral nitrogen transfer through the global river network using a land surface model

Published: August 2024

Abstract. Lateral nitrogen (N) transport from land to oceans through rivers is an important component of the global N cycle. We developed a new model of this system, called ORCHIDEE-NLAT, which simulates the routing of water in rivers, and the pertaining transport of dissolved inorganic N (DIN), dissolved organic N (DON) and particulate organic N (PON) as well as the accompanying biogeochemical processes of decomposition for DON and PON, and denitrification for DIN during the transit from land to oceans through the river network. Evaluation against global observation-based datasets reveal that the model captures both the magnitude and seasonal variations of riverine water discharges and total nitrogen (TN) flows well. The ORCHIDEE-NLAT model was then applied to reconstruct the historical evolution of global TN flows from land to rivers, as well as the denitrification of DIN within the river network. Due to anthropogenic activities (e.g. mineral fertilisers and manure application, sewage water injection in rivers and land use change) and indirect climate and CO2 effects, the TN exports are modelled to increase from 27.1 Tg N yr-1 over 1901–1910 to 40.8 Tg N yr-1 over 2001–2014, with DIN (80 %) contributing most of this increase. The annual mean TN flow and DIN denitrification rates show substantial spatial heterogeneities. The seasonal amplitude of TN flow is of similar magnitude as the large-scale spatial variability. Compared to previously published global aquatic N transfer models (IMAGE-GNM, FrAMES-N, MBM, DLEM and Global NEWS2), our model produces similar global and continental-scale TN exports to the ocean, but shows distinct patterns at finer scale spatial scales (e.g. basin scale). ORCHIDEE-NLAT could also be coupled with other land surface models such as those used in the Nitrogen Model Intercomparison Project (NMIP). Our model provides a full simulation of N transport and reactivity from soils to oceans at an unprecedented spatio-temporal resolution (daily fluxes at 0.5° globally).

Published: August 2024

Abstract. Timely and accurate high-resolution annual mapping of rice distribution is essential for food security, greenhouse gas emissions assessment and supporting for sustainable development goals. East Asia (EA), a major global rice-producing region, accounts for approximately 29.3 % of the world's rice production. Therefore, to acquire the latest rice distribution of the EA, this study proposed a novel rice distribution mapping method based on the Google Earth Engine (GEE) platform, producing a 10-meter-resolution annual rice distribution map (EARice10) of EA for 2023. A new Synthetic Aperture Radar (SAR)-based Rice distribution Mapping Index (SRMI) was firstly proposed and combined with optical indices to generate representative rice samples. In addition, a stacking-based optical-SAR adaptive fusion model was designed to fully integrate the features of Sentinel-1 and Sentinel-2 data for high-precision rice mapping in EA. The accuracy of EARice10 was evaluated using more than 90,000 validation samples and achieved an overall accuracy of 90.48 %, with both user’s and producer’s accuracies exceeding 90 %. The reliability of the product was verified by an R2 values ranging between 0.94 and 0.98 with respect to official statistics, and between 0.79 and 0.98 with respect to previous rice mapping products. EARice10 is accessible at https://doi.org/10.5281/zenodo.13118409 (Song et al., 2024).
Development of an under-ice river discharge forecasting system in Delft-Flood Early Warning System (Delft-FEWS) for the Chaudière River based on a coupled hydrological-hydrodynamic modelling approach

Published: August 2024

Abstract. Year-round river discharge estimation and forecasting is a critical component of sustainable water resource management. However, in cold climate regions such as Canada, this basic task gets intricated due to the challenge of river ice conditions. River ice conditions are dynamic and can change quickly in a short period of time. This dynamic nature makes river ice conditions difficult to forecast. Moreover, the observation of under-ice river discharge also remains a challenge since no reliable method for its estimation has been developed till date. It is therefore an active field of research and development. The integration of river ice hydraulic models in forecasting systems has remained relatively uncommon. The current study has two main objectives: first is to demonstrate the development and capabilities of a river ice forecasting system based on coupled hydrological and hydraulic modelling approach for the Chaudière River in Québec; and second is to assess its functionality over selected winter events. The forecasting system is developed within a well-known operational forecasting platform: the Delft Flood Early Warning System (Delft-FEWS). The current configuration of the systems integrates (i) meteorological products such as the Regional Ensemble Prediction System (REPS); (ii) a hydrological module implemented through the HydrOlOgical Prediction LAboratory (HOOPLA), a multi-model based hydrological modelling framework; and (iii) hydraulic module implemented through a 1D steady and unsteady HEC-RAS river ice models. The system produces ensemble forecasts for discharge and water level and provides flexibility to modify various dynamic parameters within the modelling chain such as discharge timeseries, ice thickness, ice roughness as well as carryout hindcasting experiments in a batch production way. Performance of the coupled modelling approach was assessed using “Perfect forecast” over winter events between 2020 and 2023 winter seasons. The root mean square error (RMSE) and percent bias (Pbias) metrics were calculated. The hydrologic module of the system showed significant deviations from the observations. These deviations could be explained by the inherent uncertainty in the under-ice discharge estimates as well as uncertainty in the modelling chain. The hydraulic module of the system performed better and the Pbias was within ±10 %.
Thermal regime of High Arctic tundra ponds, Nanuit Itillinga (Polar Bear Pass), Nunavut, Canada
Authors: Young Kathy L. , Brown Laura C.
Published: August 2024

Abstract. This study evaluates the seasonal and inter-seasonal temperature regime of small tundra ponds ubiquitous to an extensive, low-gradient wetland in the Canadian High Arctic. Pond temperatures can modify evaporation and ground thaw rates, impact losses of greenhouse gases, and control the timing and emergence of insects and larvae critical for migratory-bird feeding habits. We focus our study on thaw ponds with a range of hydrologic linkages and sizes across Nanuit Itillinga, formerly known as Polar Bear Pass (PBP), Bathurst Island, and compare their thermal signals to other Arctic ponds. Pond temperatures and water levels were evaluated using temperature and water level loggers and verified by regular manual measurements. Other environmental data collected included microclimate, frost table depths, and water conductivity. Our results show that there is much variability in pond thermal regimes over seasons, years, and space. Cumulative relative pond temperatures were similar across years, with ponds normally reaching 10–15 °C for short to longer periods, except in 2013, which experienced a cold summer season during which pond temperatures never exceeded 5 °C. Pond frost tables and water conductivities respond to variable substrate conditions and pond thermal patterns. This study contributes to the ongoing discussion on climate warming and its impact on Arctic landscapes.
Solicitude, Emotions, and Narrative in Technology Design Ethics
Authors: Hayes Paul , Fitzpatrick Noel
Published: August 2024

The first objective of this paper is to recognize the role of emotion and feeling in Ricœur’s “little ethics” and what they can further add to it, then to explore in more detail how solicitude as a virtue, and affective disposition more broadly, can contribute to a modern ethics of technology. Ultimately, emotions help us to understand technologies and technological ways of being today; Ricœur’s “little ethics”, along with his narrative theory, provide a framework for understanding the ethically salient aspects of technical practice, especially through the openness to the other demanded by solicitude, and essentially by emphasising emotion or feeling as a way of being in the world, and a mode of existence: one which is done with, if not sometimes because of, technology and technical practice.

Mothers who work and have preschool-aged children tend to have less interaction time and attachment with their children. As a result, children tend to imitate or engage in actions or words that do not meet their parents' expectations. Poor interaction between the parent and child environment can cause parents to experience stress, commonly referred to as parenting stress.
 
Abstract
 
Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis tingkat stres pengasuhan yang dialami oleh ibu petani menggunakan pendekatan kualitatif dengan studi kasus. Data dikumpulkan melalui wawancara mendalam, observasi, dan analisis dokumen terkait. Hasil penelitian diharapkan dapat memberikan wawasan mendalam tentang faktor-faktor yang menyebabkan stres pengasuhan pada ibu petani, serta memberikan dasar untuk pengembangan intervensi yang sesuai. Ibu yang bekerja dengan mempunyai anak usia prasekolah cenderung memiliki waktu interaksi serta kelekatan yang kurang dengan anak-anak mereka. Oleh karena itu, anak cenderung meniru atau melakukan tindakan atau kata-kata yang tidak sesuai dengan harapan orang tua. Interaksi antara lingkungan orang tua dan anak yang kurang baik dapat menyebabkan orang tua mengalami masa stres, atau biasa disebut stres pengasuhan.

Employees with high potential are needed to carry out activities in the company so that company goals can be achieved properly. Loss of qualified employees will cost the organization more time and money in recruiting and training replacements. For this reason, HR management is needed to retain existing individuals. Good HR management helps maintain existing talent in the organization by providing good compensation that can be a deterrent for employees to leave the company. Then, an unbalanced division of labor can result in an excessive workload for employees and potentially increase an employee's intention to turnover. This research uses a quantitative approach. This study aims to measure the significant influence of compensation and workload on turnover intention at PT Citramas Majutama. The results of hypothesis testing and multiple linear analysis show that compensation and workload have a significant influence on turnover intention at PT Citramas Majutama. The coefficient of determination (Adj R2) is 0.532, which indicates that the contribution of the independent variables compensation and workload to the dependent variable turnover intention is 53.2%. In comparison, the remaining 46.8% is influenced by other variables that have not been studied or are not included in the regression in this study.

Authors: Yazıcı Hikmet , Özer Aslıhan
Published: August 2024

Sigara içme, çeşitli psikolojik, sosyal, biyolojik ve farmakolojik değişkenlerle ilişkilidir. D tipi kişilik, olumsuz duygular yaşama ve bu duyguların ifade edilmesini engelleme eğilimi olarak tanımlanan psikolojik bir değişkendir. Keza depresyon da negatif duygulanımın gözlendiği yaygın bir duygu durum bozukluğudur. Sigara içme hem depresyonlu hem de D tipi kişilik özelliğine sahip bireyler arasında yaygın olarak gözlenmektedir. Bu çalışmanın temel amacı üniversite öğrencilerinin depresif eğilimleri ve D tipi kişilik özellikleriyle sigara içme arasındaki ilişkiyi incelemektir. Kesitsel nitelikteki bu çalışma 427 üniversite öğrencisi üzerinde gerçekleştirilmiştir (Sigara içen=151, Sigara içmeyen=276). Depresif belirtileri ve D tipi kişilik özelliklerini incelemek için Hisli (1989) tarafından Türkçeye uyarlanan Beck Depresyon Envanteri ile Öncü ve Köksoy-Vayısoğlu (2018) tarafından uyarlanan D tipi Kişilik Ölçeği kullanılmıştır. Sigara içme ile ilgili bilgiler ayrıca toplanmıştır. D tipi kişilik, depresif belirtiler ve sigara içme arasındaki ilişkiyi incelemek için lojistik regresyon analizi kullanılmıştır. Çalışmadan elde edilen bulgular, depresif belirtiler ile D tipi kişilik özelliklerinin sigara içme alışkanlığını anlamlı düzeyde yordadığını göstermektedir. Bu açıklama biçiminden depresif belirtiler ile D tipi kişilik özelliklerinin sigara içme alışkanlığının sürdürülmesinde önemli birer risk faktörü olduğu sonucuna varılmıştır. Buna göre üniversite öğrencileri arasında düzenlenecek sigarayı önleme ve bıraktırmaya dönük çalışmalarda D tipi kişilik ile depresif belirtilerin önemli birer değişken olarak dikkate alınması gerekmektedir.

The increase in the number of antimicrobial-resistant food-borne pathogens has become a cause for concern. There is a need to find novel strategies to combat these pathogens, in order to reduce food poisoning and even promote food security. Probiotic bacteria, including lactic acid bacteria, were isolated from palm wine (Elaeis guineensis) to evaluate antimicrobial effects on some selected spoilage and pathogenic microorganisms (Escherichia sp, Pseudomonas sp and Staphylococcus sp). They were identified by gram staining, catalase test, spore staining tests, sugar fermentation test and molecular analysis. These isolates were tested against pathogens to determine if they were capable of inhibiting their growth, and the isolates that exhibited antimicrobial properties were Bacillus cereus, Lactobacillus sp 1 and Lactobacillus sp 2. Bacillus cereus showed 18 mm against both Staphylococcus aureus and Pseudomonas aeruginosa, Lactobacillus sp 1 showed 20 mm against Pseudomonas aeruginosa, while Lactobacillus sp 2 showed 21 mm against Staphylococcus aureus. The quantitative analysis of the molecular results shows the absorbance ratio (A260/A280) for Lactobacillus sp 1 as 1.49, Bacillus cereus as 1.69 and Lactobacillus sp 2 as 1.29. The results indicated that Bacillus cereus, Lactobacillus sp 1 and Lactobacillus sp 2 exhibited probiotic potential.

This paper presents a new experimental method for the thermal analysis of solar pyrolysis of walnut shells. The method consists of two types of thermal experiments: (A) the pyrolysis of walnut shells, and (B) the heating-cooling of the biochar obtained during experiment A. Nutshells are a waste product from the pecan nut industry. The state of Sonora, Mexico, produces large volumes of walnuts and their residue. Likewise, this region has a considerable solar resource. The motivation of this study is to obtain biochar - a bi-product of high commercial value used for soil enhancement - using solar energy and agro-industrial waste. In this experiment, biomass pyrolysis of 50g of nutshells was carried out inside a stainless-steel reactor heated with concentrated radiation from a solar simulator. Three different heat fluxes were used: 234, 482, and 725 W. The maximum reaction temperatures were: 382, 498, and 674 °C respectively. The composition of the pyrolysis gases (H2, CO, CO2, and CH4) was measured and the biochar obtained was characterized. Finally, the performance of the solar reactor allowed us to identify and differentiate between evaporation, pyrolysis of cellulosic material, and lignin degradation

The Weibull distribution is commonly accepted as the most suitable model for describing the annual distribution of Direct Normal Irradiance (DNI). However, when the annual DNI is assumed to follow a Normal distribution instead of a Weibull distribution, there is a notable increase in the cumulative annual values for unfavourable and worst-case scenarios. In this research, we assess the suitability of different statistical indexes for goodness-of-fit by applying them to the annual cumulative DNI and Global Horizontal Irradiance (GHI) data recorded at six locations with varying climates. Our observations reveal that, across all locations, the Representative Solar Year (RSY) aligns with the 50% Probability of Exceedance (PoE50) of a Normal distribution fitted to the observed data. We quantify that assuming the annual DNI conforms to a Weibull distribution, as opposed to a Normal distribution, results in a substantial decrease of approximately 7% in the annual cumulative value for the worst-case scenario. Based on our analysis, we find no compelling evidence to reject the hypothesis that the annual DNI follows a Normal distribution.

Published: August 2024

This paper presents a control system with a panel-wise applied feedforward temperature controller for a molten salt receiver in star design utilizing temperature measurements in the connecting pipes between the panels and a real-time flux density measurement as inputs. It is tested in realistic cloud passage scenarios and the results are compared to the results from an earlier developed control system for the same receiver, in which the temperature controller is based on a simple feedback controller (PID) supported by a simple feedforward controller. The results show that the performance of the new feedforward controller is outstanding and could be applied to common cylindrical receiver designs as well. Nevertheless, the highly increased actuator movement of the control valves is to be further investigated.
