Published: May 2019

The article is devoted to the actual problem of studying the digestibility and metabolism of nitrogen in the body of cows when they feed haylage from the Galega orientalis. The experiment was conducted on winter rations of feeding, on black-motley cows with a productivity of 4500–5000 kg of milk. In the experiments, the methodological principle of ‘unity of intergroup differences’ and the presence of control animals was provided, which allowed to obtain objective data and reliable conclusions based on mathematical processing. An experimental assessment of haylage from Galega orientalis and Trifolium pratense is given, the influence of crops on the digestibility and use of nitrogen is studied. It was noted that the inclusion in the ration of experienced cows of haylage from Galega orientalis dairy had a beneficial effect on the digestibility of nutrients, the use of nitrogen from feed and its exchange in animals. The results showed that the animals of the experimental group consumed more nitrogen by 35.44 g than the control group. The nitrogen balance at the end of the experiment (on the 200th day of lactation) in the control group was 1.70 g, which is 17.76 g lower compared to the experimental group. Protein digestibility was 4.0% more, crude fiber — 10.96% (P <005), fat — 14.71% (P <0.05). Nitrogen was assimilated more efficiently: 40.10% from the accepted one and 64.50% from the digested one. The similar indicators in the control group were 31.70% and 54.40%, respectively. The use of nitrogen for the formation of milk in the experimental group was 33.5% of the accepted and 53.9% of the digested, in the control group these figures were at the level of 31.0% and 53.3%. It was noted that the inclusion in the ration of cows of haylage from Galega orientalis contributed to an increase in milk productivity by 9.2%, the excretion of protein with milk — by 18.4%, the content of carotene in the blood — by 12.3%.

The ‘Traffic Light’ System in the Food Industry
Authors: Berketova L. , Proshina K.
Published: May 2019

The development and implementation of the ‘Traffic Light’ marking was a consequence of the concern of Rospotrebnadzor in connection with the increase in the growth of diseases related to nutrition. In particular, the development of cardiovascular diseases, obesity, hypertension, diabetes leads to increased consumption of sugar, saturated fatty acids, trans isomers of fatty acids, salts. This raised the issue of providing clear and reliable information to the consumer about these substances. The initiator of the project of color marking ‘Traffic Light’ was the CPS. He with the participation of Research Institute of Nutrition and Biotechnology was prepared, developed and published guidelines MR 2.3.0122-18 Color indication on the labelling of food products in order to inform consumers. The purpose of these recommendations is to provide more detailed and visual information about the content of individual substances in the product: salt added sugar and fat. Color indication includes the application of red, yellow and green — depending on the level of salt, sugar and fatty acids, taking into account the daily rate of consumption of these substances. For example, green mark bread products containing table salt less than 0.2 (0.5) g and red — if it contains more than 0.48 (1.2) g. For added sugar, in particular for dairy and cottage cheese products, green identification is put at less than 5 g and red identification — at more than 9 g per day. It should be noted that the system ‘Traffic Light’ does not indicate the harm or danger of the product to human health, and informs the buyer about the color of salt, sugar and fat in this product. Similar markings are used in the USA, Great Britain and Finland. In addition to the ‘Traffic Light’ marking and the indication of food and energy value, the European Union countries are also covered by the indication of allergens, vitamins and minerals on the product package.

Planning the Plan: Around Works by Édouard Levé
Authors: Tremblay Thierry
Published: May 2019

Drawing on Aristotle's concepts of energeia, dunamis, and ergon, this article attempts to articulate a typology of the different works described in Édouard Levé’s Œuvres (2002 (French); 2014 (English)). This is carried out in the context of post-literary literature, i.e. following an aesthetics driven by the dismantling of ‘qualities’, understood as ‘accidents’, of literature's essence (literature's definition). It studies how Levé’s work, and particularly his opus magnum Œuvres (Works), displays a series of short descriptive texts that intend to remain in their potentiality, while, at the same time, actualising this very potentiality (a potentiality ‘in act’, by an operation triggered in the reader's imagination). The question is therefore less the nature of fiction or ‘what makes literature literature’ than ‘how does literature actualise its negation’.

Authors: Beattie-Smith Gillian
Published: May 2019

Dorothy Wordsworth's name, writing, and identity as an author are frequently subsumed in the plural of ‘The Wordsworths’, in her relationship as the sister of the poet, William Wordsworth. But Dorothy was a Romantic author in her own right. She wrote poetry, narratives, and journals. Nine of her journals have been published. In 1803, and again in 1822, she toured Scotland and recorded her journeys in Recollections of a Tour made in Scotland and Journal of My Second Tour in Scotland. This article considers Dorothy's two Scottish journals. It discusses them in the light of historical and literary contexts, and places of memorial.

Published: May 2019

No organization represents community of states more than the United Nations (UN). The UN provides balance, neutrality, security and stability for the international community. States invest more legitimacy in that than any other organization and through its universal membership, it serves as a road and guide to international norms.
In other hand the United Nations doesn’t have the competence to recognize states, but states recognize states. If you’re not a UN member, it doesn’t mean that you’re not a state. The four criteria for being a state are determination of a territory, the populations, the government and ability to reach agreement with others.

In this contest Republic of Kosovo is facing difficulties in joining United Nation, and his
specialized agencies, also facing the difficulties, to join international organizations as a way to secure recognition and complete statehood in international arena. Showing the will and the determination to respect international obligation regulated by each specialized agency and organization, the process of application in UNESCO is the case which shows how the states are divided in international arena, and one of the major failure of Kosovo foreign policy and diplomacy after rejection of Kosovo bid to join UNESCO in 2015.

Space Vector Modulation Strategies for Self-Sensing Three-Phase Radial Active Magnetic Bearings
Authors: Wimmer Dominik , Hutterer Markus , Hofer Matthias , Schrödl Manfred
Published: May 2019

The focus of this study lies on the investigation of the space vector modulation of a self-sensing three-phase radial active magnetic bearing. The determination of the rotor position information is performed by a current slope-based inductance measurement of the actuator coils. Therefore, a special pulse width modulation sequence is applied to the actuator coils by a conventional three-phase inverter. The choice of the modulation type is not unique and provides degrees of freedom for different modulation patterns, which are described in this work. For a self-sensing operation of the bearing, certain constraints of the space vector modulation must be considered. The approach of a variable space vector modulation is investigated to ensure sufficient dynamic in the current control as well as the suitability for a self-sensing operation with an accurate rotor position acquisition. Therefore, different space vector modulation strategies are considered in theory as well as proven in experiments on a radial magnetic bearing prototype. Finally, the performance of the self-sensing space vector modulation method is verified by an external position measurement system.

Published: May 2019

The study aimed to investigate the mass transfer kinetics and nutritional quality during osmotic dehydration (OD) and air-drying of papaya. The papaya was osmotically pretreated by different concentrations of sugar solutions (40, 50 and 60 °Brix) and osmotic solution temperatures (35, 45 and 55 °C). The ratio of fruit to the solution was kept at 1:4 (w/v) and pretreated process duration varied from 0 to 240 min. The present study demonstrated that water loss and the solute gain rate increased with the increasing of osmotic solution temperature, concentration and time. Mass transfer kinetics of osmotically pretreated papaya cubes were investigated based on the Peleg’s and Penetration models. The Peleg model showed the best fitted for water loss and solute gain whereas the Penetration model best described the water loss during osmotic dehydration of papaya. Effective diffusivity of water and solute gain was estimated using the analytical solution of Fick’s law of diffusion. Average effective diffusivity of water loss and solute gain was obtained in the range from 2.25 × 10−9 to 4.31 × 10−9 m2/s and 3.01 × 10−9 to 5.61 × 10−9 m2/s, respectively. Osmotically pretreated samples were dried with a convective method at a temperature of 70 °C. The moisture content, water activity and shrinkage of the dried papaya were decreased when the samples pretreated with a higher concentration of the osmotic solution and greater process temperature. The results also indicated that the highest osmotic solution temperature of 55 °C with the lowest concentration of 40 °Brix resulted in a significant decrease in phenolic content, antioxidant activity, and vitamin C content while higher osmotic solution concentration of 60 °Brix and the lowest temperature of the process (35 °C) retained maximum bioactive compounds.

Authors: Li Hao-Ting , Lin Shih-Chieh , Chen Cheng-Yeh , Chiang Chen-Kuo
Published: May 2019

Motivated by the recently developed distillation approaches that aim to obtain small and fast-to-execute models, in this paper a novel Layer Selectivity Learning (LSL) framework is proposed for learning deep models. We firstly use an asymmetric dual-model learning framework, called Auxiliary Structure Learning (ASL), to train a small model with the help of a larger and well-trained model. Then, the intermediate layer selection scheme, called the Layer Selectivity Procedure (LSP), is exploited to determine the corresponding intermediate layers of source and target models. The LSP is achieved by two novel matrices, the layered inter-class Gram matrix and the inter-layered Gram matrix, to evaluate the diversity and discrimination of feature maps. The experimental results, demonstrated using three publicly available datasets, present the superior performance of model training using the LSL deep model learning framework.

Authors: Dou Yinke , Zuo Guangyu , Chang Xiaomin , Chen Yan
Published: May 2019

China has built four stations in Antarctica so far, and Zhongshan Station is the largest station among them. Continuous power supply for manned stations mainly relies on fuel. With the gradual increase in energy demand at the station and cost of fuel traffic from China to Zhongshan station in Antarctica, reducing fuel consumption and increasing green energy utilization are urgent problems. This research considers a standalone renewable energy system. The polar environments and renewable energy distribution of area of Zhongshan station are analyzed. The physical model, operation principle, and mathematical modeling of the proposed power system were designed. Low-temperature performance and state of charge (SOC) estimation method of the lead–acid battery were comprehensively tested and evaluated. A temperature control strategy was adopted to prevent the battery from low-temperature loss of the battery capacity. Energy management strategy of the power system was proposed by designing maximum power point tracking (MPPT) control strategies for wind turbine and PV array. The whole power system is broadly composed of a power generator (wind turbine and PV array), an uploading circuit, a three-phase rectifier bridge, an interleaved Buck circuit, a DC/DC conversion circuit, a switch circuit, a power supply circuit, an amplifier, a driver circuit, a voltage and current monitoring, a load, battery units and a control system. A case study in Antarctica was applied and can examine the technical feasibility of the proposed system. The results of the case study reveal that the scheme of standalone renewable energy system can satisfy the power demands of Zhongshan Station in normal operation.
A Sequential Approach to Numerical Simulations of Solidification with Domain and Time Decomposition
Authors: Gawronska Elzbieta
Published: May 2019

Progress in computational methods has been stimulated by the widespread availability of cheap computational power leading to the improved precision and efficiency of simulation software. Simulation tools become indispensable tools for engineers who are interested in attacking increasingly larger problems or are interested in searching larger phase space of process and system variables to find the optimal design. In this paper, we show and introduce a new approach to a computational method that involves mixed time stepping scheme and allows to decrease computational cost. Implementation of our algorithm does not require a parallel computing environment. Our strategy splits domains of a dynamically changing physical phenomena and allows to adjust the numerical model to various sub-domains. We are the first (to our best knowledge) to show that it is possible to use a mixed time partitioning method with various combination of schemes during binary alloys solidification. In particular, we use a fixed time step in one domain, and look for much larger time steps in other domains, while maintaining high accuracy. Our method is independent of a number of domains considered, comparing to traditional methods where only two domains were considered. Mixed time partitioning methods are of high importance here, because of natural separation of domain types. Typically all important physical phenomena occur in the casting and are of high computational cost, while in the mold domains less dynamic processes are observed and consequently larger time step can be chosen. Finally, we performed series of numerical experiments and demonstrate that our approach allows reducing computational time by more than three times without losing the significant precision of results and without parallel computing.

Authors: Nguyen Trong-The , Pan Jeng-Shyang , Dao Thi-Kien
Published: May 2019

Everyday, a large number of complex scientific and industrial problems involve finding an optimal solution in a large solution space. A challenging task for several optimizations is not only the combinatorial operation but also the constraints of available devices. This paper proposes a novel optimization algorithm, namely the compact bat algorithm (cBA), to use for the class of optimization problems involving devices which have limited hardware resources. A real-valued prototype vector is used for the probabilistic operations to generate each candidate for the solution of the optimization of the cBA. The proposed cBA is extensively evaluated on several continuous multimodal functions as well as the unequal clustering of wireless sensor network (uWSN) problems. Experimental results demonstrate that the proposed algorithm achieves an effective way to use limited memory devices and provides competitive results.
Implementation and Experimental Verification of Flow Rate Control Based on Differential Flatness in a Tilting-Ladle-Type Automatic Pouring Machine
Authors: Noda Yoshiyuki , Sueki Yuta
Published: May 2019

In this paper, we study an advanced pouring control system using a tilting-ladle-type automatic pouring machine. In such a machine, it is difficult to precisely pour the molten metal into the pouring basin of the mold, as the outflow from the ladle can be indirectly controlled by controlling its tilt. Therefore, model-based pouring control systems have been developed as a part of conventional studies to solve this problem. In the results of a recent study, the efficacy of a pouring flow rate control system based on differential flatness has been verified, by performing a simulation. In this study, we apply the flow rate control system based on differential flatness to a tilting-ladle-type automatic pouring machine, using experiments to verify the efficacy of the flow rate control system in suppressing any disturbances. In these experiments, the tracking performance using the developed flow rate control system was better than the performance obtained using a conventional feed-forward-type flow rate control system.
Mixed-Media Domestic Ensembles in Roman Sicily: The House of Leda at Soluntum
Authors: Berlin Nicole
Published: May 2019

Built in the second to early-first century BCE, the House of Leda at Soluntum, a city on the northwest coast of Sicily, was renovated in the first century CE. The most prominent change to the residence was the inclusion of figural Fourth-Style wall paintings in its dining room. The fresco ensemble reveals a particular interest in the painted depiction of stone, such as an image of Leda and the swan as a marble statue and trompe l’oeil blocks of colored marble and granite from around the Mediterranean. The house renovation was not wholesale since the owner also chose to preserve a number of decorative elements from the earlier, Hellenistic-era phase of the residence, including two sculptures, cut-limestone pavements, and an intricate mosaic of an astronomical instrument. In this article I argue that the tension created between the medium of paint, and its use to mimic marble and stone, resulted in a unified, mixed-media domestic ensemble. The viewer was encouraged to compare and contrast the faux marble and stone in the dining room’s Fourth-Style frescoes with the Hellenistic-era marble and stone artworks throughout the rest of the house. This juxtaposition of older and newer decorative elements reveals that the owner of the House of Leda positioned himself as both a member of the Roman provincial elite as well as a local benefactor and custodian of Sicily’s rich Hellenistic culture.

Published: May 2019

While karst tiankengs have a higher capacity to act as safe havens for biodiversity in changing climates, little is known about their soil microorganisms. To fill this gap, we investigate the distribution and driving factors of the bacterial community in karst tiankeng systems. There is a significant difference in the soil characteristics between the inside and the outside of a karst tiankeng. At the karst tiankeng considered in this study, the bacterial composition, in terms of the operational taxonomic unit (OTU), was found to be significantly different in different soil samples, taken from diverse sampling sites within the collapsed doline or the external area, and showed a high habitat heterogeneity. The dominant phylum abundances vary with the sampling sites and have their own indicator taxa from phylum to genus. Unlike the primary controlling factors of plant diversity, the microclimate (soil moisture and temperature), soil pH, and slope dominated the distribution of the bacterial community in karst tiankeng systems. Our results firstly showed the distribution characteristics of bacterial communities and then revealed the importance of microhabitats in predicting the microbial distribution in karst tiankeng systems.
Suicidal Ideation in Bereavement: A Systematic Review
Authors: Molina Nicolette , Viola Martin , Rogers Madeline , Ouyang Daniel , Gang James , Derry Heather , Prigerson Holly G.
Published: May 2019

Background: Bereavement is associated with impaired mental health, increases in adverse health behaviors, and heightened risk of suicidal ideation, attempts, and death by suicide. The purpose of this literature review was to explore associations between cause of death and suicidal thoughts among bereaved individuals. Our aim was to compare incidence of suicidal ideation by cause of death and identify gaps in this literature to guide future research and clinical intervention. Methods: PRISMA-P guidelines were used to structure an electronic literature search in the PsycINFO, MEDLINE, and Web of Science databases. The search focused on English language studies that were published before February 2019 and sought to compare rates of suicidal ideation among bereaved people who lost a loved one to suicide, accidental overdose, cancer, dementia, cardiovascular disease, and HIV/AIDs. Results: Nine articles were identified with suicide as cause of death, zero articles for accidental overdose, zero articles for cardiovascular disease, seven articles for cancer, one article for dementia, and one article for HIV/AIDs. Given the limited number of articles generated by our search, a formal meta-analysis was not appropriate. However, a comparison of results did suggest that suicide bereavement was associated with the highest rates of suicide ideation (14.1% to 49%). Stigma, isolation, avoidance behaviors, and psychological distress were associated with suicidal thoughts among bereaved individuals, regardless of the deceased’s cause of death. Conclusions: Findings of this literature search revealed significant gaps in the literature, especially regarding thoughts of suicide in bereaved survivors of accidental overdose and cardiovascular disease. Results suggest that multiple causes of death are associated with suicidal ideation in bereavement, but that suicide bereavement may be the cause of death associated with the highest risk of suicidal ideation. More research is needed to understand the ways in which cause of death influences prevalence, risk, and protective factors associated with suicidal thoughts among bereaved individuals.
Evaluation of Repair Costs for Masonry Infills in RC Buildings from Observed Damage Data: the Case-Study of the 2009 L’Aquila Earthquake
Authors: De Risi Maria , Del Gaudio Carlo , Verderame Gerardo
Published: May 2019

The estimation of direct and indirect losses due to earthquakes is a key issue in the Performance Based Earthquake Engineering framework. In commonly adopted loss computation tools, no specific data related to masonry infill panels, widespread in moment-resisting-frame residential buildings, are available to perform a probabilistic assessment of losses. To fill this gap, specific fragility and loss functions have been recently proposed in the last years. To assess their validity and estimate the relevance of the repair costs due to infills after earthquakes with respect to the total reconstruction process, the present work analyses the Reinforced Concrete residential buildings with masonry infills struck by the 2009 L’Aquila (Italy) earthquake, focusing on the dataset of “lightly” damaged buildings, where only damage to masonry infills occurred. Based on available data related to these buildings, the observed damage scenario after L’Aquila earthquake is first obtained. The repair costs for infills are estimated given this damage scenario. The resulting estimated repair costs are then compared with the actual repair costs presented in the available literature. The percentage influence of infills on the total repair costs due to earthquakes for residential buildings is lastly computed, resulting on average equal to the fifty percent.
Review: Targeting the Transforming Growth Factor-Beta Pathway in Ovarian Cancer
Authors: Roane Brandon M. , Arend Rebecca C. , Birrer Michael J.
Published: May 2019

Despite extensive efforts, there has been limited progress in optimizing treatment of ovarian cancer patients. The vast majority of patients experience recurrence within a few years despite a high response rate to upfront therapy. The minimal improvement in overall survival of ovarian cancer patients in recent decades has directed research towards identifying specific biomarkers that serve both as prognostic factors and targets for therapy. Transforming Growth Factor-β (TGF-β) is a superfamily of proteins that have been well studied and implicated in a wide variety of cellular processes, both in normal physiologic development and malignant cellular growth. Hypersignaling via the TGF-β pathway is associated with increased tumor dissemination through various processes including immune evasion, promotion of angiogenesis, and increased epithelial to mesenchymal transformation. This pathway has been studied in various malignancies, including ovarian cancer. As targeted therapy has become increasingly prominent in drug development and clinical research, biomarkers such as TGF-β are being studied to improve outcomes in the ovarian cancer patient population. This review article discusses the role of TGF-β in ovarian cancer progression, the mechanisms of TGF-β signaling, and the targeted therapies aimed at the TGF-β pathway that are currently being studied.

Published: May 2019

Crosstalk between lysosomes and mitochondria plays a central role in Parkinson’s Disease (PD). Lysosomal function may be influenced by mitochondrial quality control, dynamics and/or respiration, but whether dysfunction of endocytic or autophagic pathway is associated with mitochondrial impairment determining accumulation of defective mitochondria, is not yet understood. Here, we performed live imaging, western blotting analysis, sequencing of mitochondrial DNA (mtDNA) and senescence-associated beta-galactosidase activity assay on primary fibroblasts from a young patient affected by PD, her mother and a healthy control to analyze the occurrence of mtDNA mutations, lysosomal abundance, acidification and function, mitochondrial biogenesis activation and senescence. We showed synergistic alterations in lysosomal functions and mitochondrial biogenesis, likely associated with a mitochondrial genetic defect, with a consequent block of mitochondrial turnover and occurrence of premature cellular senescence in PARK2-PD fibroblasts, suggesting that these alterations represent potential mechanisms contributing to the loss of dopaminergic neurons.

Authors: Taha Abdullah , Amani Mahmood
Published: May 2019

This paper provides an integrated overview of the water shutoff operations, starting from the causes to the solutions. The paper begins with explaining the benefits of eliminating excessive water production. Then, the different types of water production and their properties are explained. The paper also focuses in reviewing the disadvantages of producing unwanted water as well as the sources of it, followed by an explanation of the methodology for identifying the problem. Then, the chemical solutions for water shutoff are reviewed which are generally applied to solve the excessive unwanted water production in the reservoir or near the wellbore area. Finally, the paper illustrates the common mechanical solutions for water shutoff within the wellbore. The aim behind this paper is to provide a general description of identifying the unwanted water production sources and the common practices for water shutoff operations.

Rhabdomyolysis is caused by extensive damage to skeletal muscles resulting in elevated creatine phosphokinase (CPK), Lactate dehydrogenase (LDH), and aspartate aminotransferase (AST), leading to life-threatening consequences like acute renal failure, cardiac arrhythmias, and hyperthermia. A variety of causes for muscle damage are known, and one of the most common is drug-induced. Statins and many other agents are known to induce muscle damage, but here we report Entresto™ (Sacubitril/Valsartan) induced rhabdomyolysis which has not been previously reported as solely responsible in the literature.
Emerging Countries and the Effects of the Trade War between US and China

The aim of the paper is to examine the effects of the US–China trade war on both countries and some emerging economies. Two scenarios are examined, one where only US protectionist measures are considered, and another in which Chinese retaliation is taken into account, using the GTAP (Global Trade Analysis Project) Computable General Equilibrium model. The results showed that, on one hand, the trade war would lead to a reduction in US trade deficit and an increase in domestic production of those sectors affected by higher import tariffs and Chinese producers and consumers would bear the lion’s share of the burden of the trade war. But, on the other hand, both countries and the world as a whole would lose in terms of welfare, due to the significant reduction in allocative efficiency, especially in the US, and the loss of terms of trade in the Chinese case. With the increase in protectionism between the two largest global economies, some important emerging countries, not directly involved in the trade war, would benefit by the shift in demand to sectors where they have comparative advantages.
GA-BP in Thermal Fatigue Failure Prediction of Microelectronic Chips
Authors: Han Zhongying , Huang Xiaoguang
Published: May 2019

A thermal fatigue life prediction model of microelectronic chips based on thermal fatigue tests and solder/substrate interfacial singularity analysis from finite element method (FEM) analysis is established in this paper. To save the calculation of interfacial singular parameters of new chips for life prediction, and improve the accuracy of prediction results in actual applications, a hybrid genetic algorithm–artificial neural network (GA–ANN) strategy is utilized. The proposed algorithm combines the local searching ability of the gradient-based back propagation (BP) strategy with the global searching ability of a genetic algorithm. A series of combinations of the dimensions and thermal mechanical properties of the solder and the corresponding singularity parameters at the failure interface are used to train the proposed GA-BP network. The results of the network, together with the established life prediction model, are used to predict the thermal fatigue lives of new chips. The comparison between the network results and thermal fatigue lives recorded in experiments shows that the GA-BP strategy is a successful prediction technique.
Assessment of the Coastal Vulnerability Index in an Area of Complex Geological Conditions on the Krk Island, Northeast Adriatic Sea

Published: May 2019

This study presents a vulnerability assessment methodology that was developed to analyze the Croatian Eastern Adriatic Coast (CEAC), which has extremely complex geomorphology. Local coastal retreat, slope instability phenomena, and the influence of marine erosion play a significant role in coastal geohazards in the southeastern coastal area of the Krk Island (Kvarner area, northeastern channel part of the Adriatic Sea). Recent studies emphasize the need to develop an adequate methodology to monitor its evolution and define adequate risk management strategies. The vulnerability analysis was performed on the basis of the available data, taking into account local geological and oceanographic conditions. The coastal vulnerability analysis of the CEAC presents an adaptation of the existing methodology, emphasizing the significance of the geological factor, and providing novel elements of the parameter analysis (i.e., coastal slope, beach width, and significant wave height). This methodology was adapted and improved for the local rocky coast, but can be used on other complex rocky coasts worldwide. The calculated Coastal Vulnerability Index (CVI) around the Stara Baška settlement should be considered to have priority over the vulnerable areas in further monitoring and investigations.

A new method for sensitivity analysis of water depths is presented based on a two-dimensional hydraulic model as a convenient and cost-effective alternative to Monte Carlo simulations. The method involves perturbation of the probability distribution of input variables. A relative sensitivity index is calculated for each variable, using the Gauss quadrature sampling, thus limiting the number of runs of the hydraulic model. The variable-related highest variation of the expected water depths is considered to be the most influential. The proposed method proved particularly efficient, requiring less information to describe model inputs and fewer model executions to calculate the sensitivity index. It was tested over a 45 km long reach of the Richelieu River, Canada. A 2D hydraulic model was used to solve the shallow water equations (SWE). Three input variables were considered: Flow rate, Manning’s coefficient, and topography of a shoal within the considered reach. Four flow scenarios were simulated with discharge rates of 759, 824, 936, and 1113 m 3 / s . The results show that the predicted water depths were most sensitive to the topography of the shoal, whereas the sensitivity indices of Manning’s coefficient and the flow rate were comparatively lower. These results are important for making better hydraulic models, taking into account the sensitivity analysis.
National Trauma and Romantic Illusions in Percy Shelley’s The Cenci
Authors: Kasmer Lisa
Published: May 2019

Percy Shelley responded to the 1819 Peterloo Massacre by declaring the government’s response “a bloody murderous oppression.” As Shelley’s language suggests, this was a seminal event in the socially conscious life of the poet. Thereafter, Shelley devoted much of his writing to delineating the sociopolitical milieu of 1819 in political and confrontational works, including The Cenci, a verse drama that I argue portrays the coercive violence implicit in nationalism, or, as I term it, national trauma. In displaying the historical Roman Cenci family in starkly vituperous manner, that is, Shelley reveals his drive to speak to the historical moment, as he creates parallels between the tyranny that the Roman pater familias exhibits toward his family and the repression occurring during the time of emergent nationhood in Hanoverian England, which numerous scholars have addressed. While scholars have noted discrete acts of trauma in The Cenci and other Romantic works, there has been little sustained criticism from the theoretical point of view of trauma theory, which inhabits the intersections of history, cultural memory, and trauma, and which I explore as national trauma. Through The Cenci, Shelley implies that national trauma inheres within British nationhood in the multiple traumas of tyrannical rule, shored up by the nation’s cultural memory and history, instantiated in oppressive ancestral order and patrilineage. Viewing The Cenci from the perspective of national trauma, however, I conclude that Shelley’s revulsion at coercive governance and nationalism loses itself in the contemplation of the beautiful pathos of the effects of national trauma witnessed in Beatrice, as he instead turns to a more traditional national narrative.
