Solid-liquid Equilibrium in the System 2-Keto-L-gulonic Acid + Sodium-2-keto-L-gulonate + Water
Authors: Jirasek Fabian , Burger Jakob , Hasse Hans
Published: April 2021

The solid-liquid equilibrium (SLE) in the ternary system 2-keto-L-gulonic acid (HKGA) + sodium-2-keto-L-gulonate (NaKGA) + water was studied experimentally at temperatures between 275 and 313 K and ambient pressure. At these conditions, HKGA and NaKGA precipitate as monohydrates: HKGA H2O and NaKGA H2O, respectively. Phase diagrams with one eutonic point are found for all temperatures. A thermodynamic model of the SLE that is based on an extended version of the Debye-Hückel theory was developed and the dissociation constant of HKGA as well as the solubility products of HKGA H2O and NaKGA H2O were determined. The agreement between the experimental data and the results from the model is excellent.

Thermal, Caloric and Transport Properties of the Lennard–Jones Truncated and Shifted Fluid in the Adsorbed Layers at Dispersive Solid Walls
Authors: Lautenschläger Martin P. , Hasse Hans
Published: April 2021

Fluid properties change when the fluid is adsorbed at a wall. The effect of the adsorption on the fluid properties was studied here by molecular simulation. There is much previous work in this field on fluids in nanochannels that are so small that the adsorbed layers on both walls interfere. In this work, the channel width was so large that the adsorbed layers did not interfere, such that information on the adsorbed layer on single walls was obtained and average values of thermodynamic properties of the fluid in that layer were determined. The studied fluid properties are: pressure p, density ρ, internal energy u, enthalpy h, isobaric heat capacity cp, thermal expansion coefficient αp, thermal conductivity λ, shear viscosity η and self-diffusion coefficient D. For the study, non-equilibrium molecular dynamics simulations were carried out. The fluid and the solid were modelled with the Lennard–Jones potential truncated and shifted at r∗c=2.5σ. The overall density of the fluid was ρ¯=0.8. The overall temperature and the solid–fluid interaction were varied. The corresponding bulk states are liquid or supercritical. The results for the fluid properties in the adsorbed layer were compared to the corresponding bulk values and the deviations are generally below 15%.
The Politics of Cash Transfers in Kenya
Authors: Opalo Ken Ochieng'
Published: April 2021

How does public opinion on the causes of poverty and deservingness condition support for government support for the poor? This paper answers this question with a focus on direct cash transfers. I find minimal partisan differences in perceptions of the causes of poverty and deservingness, but significant differences in opinions on how to finance cash transfers. Supporters of the incumbent president are more likely to support increasing consumption taxes to finance these programs compared to opposition supporters. These findings suggest that partisan differences about social spending may exist even when there is agreement on the causes of poverty and deservingness.

Simultaneous Determination of Thermal Conductivity and Shear Viscosity using Two-gradient Non-equilibrium Molecular Dynamics Simulations
Authors: Lautenschläger Martin P. , Horsch Martin T. , Hasse Hans
Published: April 2021

ABSTRACTA method for the simultaneous determination of the thermal conductivity λ and the shearviscosity η of fluids by non-equilibrium molecular dynamics simulations is presented and testedusing the Lennard-Jones truncated and shifted fluid as example. The fluid is studied under thesimultaneous influence of a temperature gradient∂T/∂y and a velocity gradient ∂v/∂y and the resulting heat flux and momentum flux are measured todetermine λ and η. The influence of the magnitude of ∂T/∂y and ∂v/∂y on λ and η is investigated.The cross-effects are negligible, even for large gradients. The same holds for the influenceof ∂T/∂y on λ. However, there is a significant influence of ∂v/∂y on η, i.e.shear-thinning. The two-gradient method is applied in different ways: for small ∂T/∂ytemperature-averaged values of λ and η are obtained. As ∂T/∂y has no significant influenceon the results, simulations with large ∂T/∂y are evaluated using the local-equilibriumassumption, such that values are obtained at different temperatures in a single simulation. Inaddition to the results for λ and η, also results for the self-diffusion coefficient D aredeterminedared displacement. The new two-gradient method is d yields accurate results.

On the Quantification of Crowd Wisdom, Optimal Crowd Size, and the Mean-Median Dilemma
Authors: Lorenz Jan
Published: April 2021

Crowd wisdom is a fascinating metaphor in the realm of collective intelligence. However, even for the simple case of estimation tasks of one continuous value, the quantification of the phenomenon lacks some conceptual clarity. Two interrelated questions of quantification are at stake. First, how we can quantify the degree of crowd wisdom in a sample and how it can be distinguished from the individual wisdom of its members? Two measures will be presented and discussed. One can also be used to quantify optimal crowd sizes. Even purely statistical, it turns out that smaller crowds are more advisable when intermediate systematic errors in estimating crowds are frequent. In such cases, larger crowds are more likely to be outperformed by a single estimator.Second, how can we best aggregate the collective decision from a sample of estimates, with the mean or the median? Arguments are not only statistical but also related to the question if democratic decision-making can have an epistemic quality.A practical result of this study is that we should usually aggregate democratic decisions by the median, but have a backup with the mean when the decision space has two natural bounds and societies polarize.
Empathy in non-altruistic settings: Conceptualization and operationalization in business
Authors: Bhattacharya Mainak
Published: April 2021

A hundred years since the first mention of the word empathy in the English language, scientists and philosophers have been unable to arrive at a common consensus on its precise definition. Common wisdom associates empathy with vicarious emotional arousal or altruism. This study conducts a systematic review of research work in business studies dealing with empathy. The method used comprises applying lower-level abstract taxonomy to empathy, for the first time, in external business stakeholder interaction situations of sales, marketing, and customer service. The measurement scales used in the studies are analyzed to showcase mental processes at stake during the act of empathy, the theorized functions, and expected business outcomes of empathy. Implications are drawn for various aspects of managerial decision making. The study suggests a novel framework to execute a more nuanced grade examination of processes involved in empathy and reducing subjectivity in conceptual definitions. The study also calls for overhauling empathy measurement scales, mainly to suit adaptations in empirical business studies.

Rain-induced failures on residual soil slopes
Authors: Dodagoudar G. R. , Venkatachalam G.
Published: April 2021

The hilly region of Western Ghats, India, is a site of frequent landslides, which have caused a severe loss of lives and property. The region is characterised by the presence of residual soils, rugged topography, high relief, and medium to steep slopes. During the heavy rainfall, the pore water pressure is built quickly in the residual soils.

This study deals with a probabilistic stability analysis of rain-induced failures on residual soil slopes. A mass movement analysis is also attempted using the momentum transfer law for the Parmachi Landslide. Attention is given to the associated risk of sliding, incorporating important factors, which influence the failure of natural slopes. A landslide hazard prediction procedure is presented and its application to debris flows at Parmachi is shown as an example. The probability of failure is evaluated in conjunction with the consequences of failure. Decision analysis is also tried with the probabilistic slope stability analysis of the Parmachi Landslide. The evaluated risk and decision theory are used to suggest a decision-making process for landslide hazard mitigation.
Problems of river degradation in the Kathmandu Valley
Authors: Pradhananga R. P.
Published: April 2021

The speedy degradation of rivers in the Kathmandu Valley has led to the failure of bridges, historical sites, and riverbanks. The present ad hoc practice of constructing protection measures has to be given a second thought. An integrated approach including engineering, legal, and social aspects can stop the speedy degradation of rivers. The proposed engineering measures include short-, medium-, and long-term stabilisation of the Chobhar Gorge including the construction of a series of check dams at a regular interval. The legal and other measures include banning sand extraction, construction of riverside road, preventing encroachment of floodplain, reducing sand demand, controlling the discharge of acidic effluents into the river, and creating awareness.
Rock Support Design for the Khimti I Hydropower Project
Authors: Sunuwar S. C. , Shrestha G. L. , Neill B. O'
Published: April 2021

The Khimti I Hydropower Project (KHP) is the first project where the Norwegian Method of Tunnelling (NMT) was applied in Nepal. The method was found to be appropriate for drill-and-blast tunnels in jointed, fractured, and sheared rocks, which tend to overbreak. A combination of rock bolting with wet fiber reinforced shotcrete is the main rock support method in the NMT. In exceptionally poor rock (with squeezing conditions) reinforced ribs of shotcrete with a concrete invert were generally found to be a more efficient and cost effective. Cast concrete lining was also used occasionally at the KHP, mainly in overbreak areas with high groundwater discharge.

The main advantage of the NMT is that each stretch of tunnel is evaluated using the Q-System of rock classification and then only the required amount of support is applied. This procedure takes optimum advantage of the self-supporting capacity of the rock.

There were some problems encountered during application of the NMT at the KHP, but the adoption of 10 site -specific design principles made the method more practical and effective. It was generally experienced that the NMT was simple to use and gave appropriate guidelines that could be applied across a very broad range of rock conditions. At Khimti, the peak excavation rates reached 63 m/week and 72 m/week in 25 m2 and 14 m2 tunnels, respectively. The average excavation rates (including full support) were 10 m and 35 m per week in "Extremely Poor" and "Poor to Fair" rock conditions, respectively.
Engineering geological zoning of the Scorillo Dam site, Romania
Authors: Marunteanu Cristian , Durdun Ion
Published: April 2021

A model of engineering geological classification and zoning of the Scorillo Dam site in Romania is proposed to optimise the design of the dam and of the grout curtain. The rock mass was classified into four categories: from 1 (good) to 4 (very poor), according to the rock mass quality (RMQ) at the dam site. Parameters available and used to determine the RMQ were lithology, degree of weathering and fragmentation, rock quality designation (RQD), and modulus of elasticity (E). Based on the study, a new design of the dam, its slopes, and the grout curtain was carried out.
Ash disposal - mine fires - environment- an Indian dilemma
Authors: Michalski S. R. , Gray R. E.
Published: April 2021

Coal combustion ash disposal at mine sites may provide a means to deal with the serious problems of coal mine fires, orphaned mined land and coal ash disposal in India. India produces about 70 million metric tons per annum (Mta) of coal ash from the combustion of 320 Mta of domestically produced coal, the average ash content being about 30-35 per cent as opposed to an average ash content of less than 10 per cent in the U.S. In other words, India produces coal ash at about triple the rate of the U.S. Currently, 95 per cent of this ash is sluiced into gigantic slurry ponds, many located near urban areas and consuming vast amounts of premium land. Conversely, the Jharia Coalfield produces about 30 Mta of this ash and also contains the world's largest complex of underground coal mine fires. The fires occupy an aggregate surface area of about 10 square kilometres where the land surface is extremely degraded. Similarly, the Singrauli Coalfield, suffers from the environmental effects of open cast mining, overburden dumps for mine waste and an enormous coal combustion ash disposal problem, which is probably the largest such problem in India. Coal combustion ash haulback to the Jharia and Singrauli Coalfields as well as to other coalfields in India can find beneficial use by:

- Controlling mine fires through surface and underground sealing with coal combustion ash,

- Filling open-cast mine pits, depressed, and subsided areas,

- Filling abandoned underground workings to control ground subsidence,

- Reducing ground water flow through mine backfill to retard leaching of acid or metals forming constituents, and

- Serving as a soil amendment to restore soil fertility.

Placement of ash in surface and underground mines whether in the Jharia or Singrauli Coalfields or elsewhere in India, can provide an efficient, cost-effective method to remove significant quantities of ash from pond disposal while at the same time contributing to mine fire and subsidence abatement, mined land reclamation and restoration of land productivity. Wise natural resource management suggests a reasonable approach to disposal and beneficial use of coal ash is to return it to its original location – the mine.
GIS for groundwater management in cities on volcanoes: example from the Colli Albani Region, Rome, Italy
Authors: Giordano G. , Mazza R. , Cecili A. , Capelli G. , Rita D. De , Bigi G. , Rodani S.
Published: April 2021

The Colli Albani volcanic complex contains the deposits of Quaternary stratovolcano. They cover over 1500 km2 around the city of Rome and have formed one of the most important aquifers for the city since the Roman age. Presently the volcano is quiescent, although it is characterised by shallow seismicity and gas emissions along the main fault systems.

The area has undergone rapid urbanisation during the last 50 years and is presently characterised by intense, diffuse, and uncontrolled water withdrawal. In this paper we document a significant drop of water table, locally up to 100 m, which occurred during the last ten years. During the same period, there occurred several episodes of CO2 release in air that threatened human and animal life. We suggest a possible interplay between the dynamics of the hydrogeological system and the still active hydrothermal system, and present a Geographic Information System designed for the zonation of the area into various ‘water-yielding capacity’ classes as a function of aquifer depletion, urbanisation, and land use as well as hydrothermal activity and seismicity.
Effect of land use on the development of slope instability in the Neka-Rood Watershed, Iran
Authors: Uromeihy Ali
Published: April 2021

Land use can be considered as one of the most important parameters in the development of slope instability. It is a factor that continuously changes the land surface condition with time. Therefore, it should be considered when analysing the potential of slope instability and preparing a landslide hazard zonation map. Land use influences the characteristics of land surface and may cause changes in its behaviour towards the processes such as weathering and erosion affecting the inherent properties of the ground.

The results show that between 1955 and 1993 more than 30% of the land has been converted from forestland to pastureland in the Neka-Rood Watershed of Iran. This conversion accelerated the slope instabilities in the watershed, where 90% of landslides were recorded in the pastureland and only 8% in the forestland. It was also noted that the geological conditions have greatly influenced the potential of land erosion and consequently the type of land use.
Study and modelling of a heterogeneous debris slide
Authors: Barisone G. , Odetto G.
Published: April 2021

The paper describes a new approach to the study of heterogeneous debris slides. For this purpose, an investigation was carried out in the field as well as the laboratory. The two-dimensional computation techniques of Distinct Element Method were applied for the prediction of the displacements in the landslide. The predictions accord well with the results of inclinometer measurements in the landslide. This technique can he applied with some modifications to many soils that can be treated as heterogeneous debris (silty-clayey matrix with big boulders), such as those found along the Alpine arc. The study also demonstrates that it is possible to adapt the mathematical models implemented in the up-to-date calculation programs for particular needs, even if this is to the validity limits of the theory.
Landslides and their mitigation in Gangtok, Sikkim
Authors: Larsen Jan Otto , Grimstad Eystein , Bhasin Rajinder , Dhawan Ashok K. , Singh Rajbal , Verma S. K.
Published: April 2021

A study of landslides was carried out around Gangtok, the capital city of Sikkim. Apart from a general survey of the area, detailed investigations were made at Chanmari and Tathangchen as well as along the National Highway 31A. Among various landslides, rockslides predominate and they fail mainly along the foliation planes dipping parallel to the hillside. For example, the Burdang Landslide and Tathangchen Landslide are basically rockslides on schist or phyllite.

To monitor the ground movement at the Chanmari Landslide, six control points were set along the existing drainage channel. The movement of the points is recorded twice a month. Also, four piezometers are se t above the landslide scarp to measure the pore water pressure. A similar system with four control points and two piezometers is also established along the main road at the Chanmari Village.

As rainfall is the main triggering factor, control of surface and subsurface runoff is the most important protection measure. The recommended mitigation measures include the construction of drains and retaining walls. It is also recommended to enforce the Government Building Regulations in the landslide-prone areas.

Published: April 2021

Proximal junctional problems are among the potential complications of surgery for adult spinal deformity (ASD) and are associated with higher morbidity and increased rates of revision surgery. The diverse manifestations of proximal junctional problems range from proximal junctional kyphosis (PJK) to proximal junctional failure (PJF). Although there is no universally accepted definition for PJK, the most common is a proximal junctional angle greater than 10° that is at least 10° greater than the preoperative measurement. PJF represents a progression from PJK and is characterized by pain, gait disturbances, and neurological deficits. The risk factors for PJK can be classified according to patient-related, radiological, and surgical factors. Based on an understanding of the modifiable factors that contribute to reducing the risk of PJK, prevention strategies are critical for patients with ASD.

The Law Institute of recognition of a State is one of the most difficult, controversial, and dynamically developing institute of the national and the international law. However, at present there are many states that are not officially recognized by most other states, which since the beginning of the 1990s began to be designated by the term “unrecognized states”, “de facto countries”, “self-proclaimed states”, etc. The presence of unrecognized states is a complex problem in the theory and practice of international relations, since, possessing all other signs of statehood, they do not have international diplomatic recognition and cannot be members of the UN. Today there are about 120 unrecognized states in the political map of the world, which are recognized by the territory of 60 countries. The problem of unrecognized states is also relevant for the post-Soviet space, since after the collapse of the USSR, several territorial entities arose, the status of which has not been recognized at the international level so far. In the proposed article, the authors tried to find out the reasons for the emergence of unrecognized states, identified the main features of such territorial entities and possible options for their further fate as countries that do not have the status of a generally recognized state. The protracted legal uncertainty of the status of the unrecognized states aggravates the problem of further international cooperation of the world community from the point of view of global security and the possible threat of conflicts that could cause a world political crisis.

Inteligência Artificial Em Otimização De Centrais Hidrelétricas
Authors: Neco Diego Correa
Published: April 2021

Este trabalho apresenta a implementação de uma rede neural Multilayer Perceptron para o levantamento do diagrama de colina (diagrama do campo de operação de uma turbina hidráulica) para posteriormente obter o controle do modo operativo do grupo gerador. Esta rede utiliza uma série de dados de ensaios práticos desenvolvidos através do programa Matlab com o algoritmo de Levenberg-Marquadt que é modelado utilizando Inteligência Artificial o comportamento de uma turbina Francis com o intuito de otimizar a central hidrelétrica aumentando a eficiência do grupo gerador. As curvas de colina são usualmente obtidas para a operação tradicional em rotação fixa. Este diagrama determina o campo básico de funcionamento da turbina, entretanto nem sempre é possível fazer o levantamento em campo desse diagrama, ou seja, com a aplicação deste algoritmo otimizamos o tempo e possíveis erros em um levantamento manual de dados.
Le istituzioni dell'uomo, il diritto e l'economia. Una breve riflessione a partire dal pensiero di Giambattista Vico
Authors: Costa Paolo
Published: April 2021

Il rapporto tra istituzioni ed economia è spesso acriticamente rappresentato come rapporto tra Stato e mercato, tra autorità della legge e libertà della concorrenza. Gli intrecci storici e metodologici tra i fenomeni in questione e le relative scienze sono in realtà più profondi. Sembrano condurre, attraverso percorsi epistemici ora più percepibili ora più carsici, a comuni matrici antropologiche, già visibili ad esempio in un autore epocale quale Giambattista Vico.
