Rocking response of liquid-filled cylindrical tanks

The hydrodynamic response of liquid-filled storage tanks subjected to translational earthquake shaking has been the focus of studies for more than 75 years. In service, tanks experience six components of seismic input, with rocking due to support flexibility and/or rotational components of ground motion. Published theory for predicting hydrodynamic responses in rigid cylindrical tanks due to rotational seismic input is examined. Analytical solutions for pressure in the fluid and on the tank wall, and base moment are modified to account for the effects of angular displacements at the base. A finite element model of a water-filled cylindrical tank using the Arbitrary Lagrangian and Eulerian (ALE) solver in LS-DYNA is used to demonstrate the efficacy of the proposed expressions for three base rocking motions. Results from the modified analytical solutions and the finite element model are in excellent agreement.

Torture Experiences and Mental Health Problems among Refugees: The Impact of Repatriation to North Korea on Mental Disorders

ABSTRACT Psychological distress is prevalent among North Korean refugees, but their associations with forced repatriation to North Korea have not been empirically investigated. In this study, we defined forced repatriation as a constellation of torture experiences and investigated whether forced repatriation is associated with various clusters of psychological symptoms among North Korean refugees. Six hundred thirty-two North Korean refugees participated in this study. Significant differences in the psychological symptoms of refugees with and without the experience of forced repatriation were found. As a result of past exposure to torture, refugees who experienced forced repatriation reported more severe psychological symptoms than their counterparts without such experience. The findings suggest that premigration trauma shares differential associations with different clusters of psychological symptoms.
Analysis of ballast breakage in ballast bed when using under sleeper pads

ABSTRACT A breakable model of ballast particle is developed by using the Discrete Element Method (DEM). A method of modelling the Under Sleeper Pad (USP) by using ‘elastic rods’ is proposed. After integrating the model of the sleeper, USP and ballast, the dynamic train load is applied to analyze the dynamic response of the ballast bed. The following results can be drawn: (1) The USP increases the contact area between the sleeper and ballast particles, and effectively reduces the contact stress. Comparing the track using USP to the traditional ballast track, maximum stress in ballast is reduced by 26.10%, and the average stress is reduced by 3.22%. (2) The breakage of ballast particles in the upper part the ballast bed of the traditional ballast track is mostly overall damage, while the breakage in the lower part mainly occurs at the sharp corners. Using the USP can mitigate the overall breakage at the upper part. (3) The USP can reduce both the tensile failure and shear failure of ballast breakage compared to the traditional ballast track. (4) When using the USP, the ballast settlement is faster to be stable and with a smaller value under long-term train loads.
Significance of Measuring Dimensions of Lumbar Lamina and Spinal Canal – A Cadaveric Study

Introduction: The incidence of lumbar nerve root compression and surgeries for its treatment likelaminectomy, laminotomies are increasing. Similarly, intralaminar screw insertion and use of laminar hooksfor stabilization is also gaining popularity. The dimensions of lumbar lamina are of importance for designingof lumbar spinal implants used. Method: The present study was under taken to measure vertical height oflumbar lamina and width of lumbar vertebral canal in cadavers. Lumbar spine was exposed from posteriormidline approach in 20 formalin preserved cadavers. The dimensions of lumbar lamina L1 to L5 wererecorded with the help of Digital Vernier Caliper after removal of soft tissue from the vertebrae. The datawas analyzed using SPSS software version 23. Result: Range of transverse width of vertebral canal ofL1 and L2 was 14-23 mm. It gradually reduces in L3, L4 and L5 (12-21 mm). There was no significantdifference in width of vertebral canal between Male and female. Mean height of lamina at junction withtransverse process at L2 was (25.7±2.8mm) which reduced from L3, L4 and was lowest in L5 (20.8±2). Mean height of lamina at junction with Spinous process increased from L1 to L2 (27.55±3.3) and decreasedfrom L3, L4 and L5 being smallest (24.3±2.7). The gender, right and left differences for the dimensions oflumbar vertebral lamina were statistically insignificant. In 35 percent cases the spinous processes were fusedwhich was an accidental finding. Conclusion: The data so collected will be of great significance for spinalsurgeons and for designing of implant around this region.
Deep Learning Enabled Autoencoder Architecture for Collaborative Filtering Recommendation in IoT Environment

: The era of the Internet of things (IoT) has marked a continued exploration of applications and services that can make people’s lives more con-venient than ever before. However, the exploration of IoT services also means that people face unprecedented difficulties in spontaneously selecting the most appropriate services. Thus, there is a paramount need for a recommendation system that can help improve the experience of the users of IoT services to ensure the best quality of service. Most of the existing techniques—including collaborative filtering (CF), which is most widely adopted when building recommendation systems—suffer from rating sparsity and cold-start problems, preventing them from providing high quality recommendations. Inspired by the great success of deep learning in a wide range of fields, this work introduces a deep-learning-enabled autoencoder architecture to overcome the setbacks of CF recommendations. The proposed deep learning model is designed as a hybrid architecture with three key networks, namely autoencoder (AE), multi-layered perceptron (MLP), and generalized matrix factorization (GMF). The model employs two AE networks to learn deep latent feature representations of users and items respectively and in parallel. Next, MLP and GMF networks are employed to model the linear and non-linear user-item interactions respectively with the extracted latent user and item features. Finally, the rating prediction is performed based on the idea of ensemble learning by fusing the output of the GMF and MLP networks. We conducted extensive experiments on two benchmark datasets, MoiveLens100K and MovieLens1M, using four standard evaluation metrics. Ablation experiments were conducted to confirm the validity of the proposed model and the contribution of each of its components in achieving better recommendation performance. Comparativeanalyses were also carried out to demonstrate the potential of the proposed model in gaining better accuracy than the existing CF methods with resistance to rating sparsity and cold-start problems.
Seeing things differently: How are environmental conditions perceived and why does it matter?

Author(s): Mallette, Angela; Plummer, Ryan; Baird, Julia | Abstract: Parks and protected areas that provide recreational opportunities for visitors are often faced with a set of unique management challenges. Primarily, this includes balancing the preservation of the ecosystem with recreational use, often involving the mitigation of visitor behaviors. As well, various groups that may interact with these areas often have conflicting priorities for or opinions on management actions. In order to promote sustainable visitor behaviors, increase support for management initiatives, and address some of these conflicting opinions, an understanding of how environmental conditions are perceived among user groups is needed. Therefore, this study sought to illuminate how two groups that differ in their levels of experience and knowledge with respect to a protected area with high levels of visitation perceive the state of its environment. A survey was administered to people identified as “experts” on the Niagara Glen Nature Reserve (Ontario, Canada) as well as to those identified as more casual “visitors” to the reserve. Perceptions of ecological conditions are compared to empirical measurements. For both visitors and experts, the overall perceptions of environmental conditions differed significantly from the ecological data, with visitors generally providing higher ratings of ecosystem conditions, whereas experts generally provided lower ones. Visitors and experts also differed significantly from one another in their perceptions—a meaningful finding for understanding intergroup conflicts as well as the basis for support for management initiatives. The findings highlight the importance of considering perceptions of environmental conditions between groups, and of understanding how perceptions relate to measured ecological data.
Potential foraminiferal nitrate transport in sediments in contact with oxic overlying water

Sedimentary denitrification accounts for more than half of the global marine fixed nitrogen loss, but this removal is often restricted by nitrate diffusive supply in sediments. The results of this study showed that foraminiferal nitrate transport may supply nitrate below the nitrate penetration depth and promote nitrogen removal in sediments in contact with oxic overlying water. Six dominant foraminiferal species in the Yellow Sea sediments accumulated high concentrations of intracellular nitrate (25–68 mM), which is 1000 times higher than the maximum pore water nitrate concentration. Notably, this is the first time that Protelphidium tuberculatum, the most dominant species at almost all stations, is reported to have elevated intracellular nitrate. P. tuberculatum contributes 45% to 92% of the foraminiferal intracellular nitrate pools and plays an important role in foraminiferal nitrate transport. The potential foraminiferal denitrification rates below the nitrate penetration depth induced by foraminiferal nitrate transport ranged from 4 to 117 μmol N m−2 d−1 and contributed 3% to 81% of sedimentary denitrification. The intensity of foraminiferal nitrate transport showed a negative correlation with the nitrate penetration depth and positively correlated with the chlorophyll a (Chl a) and chloroplastic pigment equivalent concentrations, which indicate that shallower redox depth (nitrate penetration depth) and increased food supply (Chl a, chloroplastic pigment equivalent) may promote foraminiferal nitrate transport. The trophic oxygen model was modified by adding the pore water nitrate to explain foraminiferal nitrate transport in various marine environments, and this modified trophic oxygen model predicts the observed high foraminiferal nitrate transport intensity.
Good Business Practices Improve Productivity in Myanmar’s Manufacturing Sector

Abstract We investigate the relationship between business practices and enterprise productivity using panel data with matched employer and employee information from Myanmar. The data show that micro, small, and medium-sized manufacturing enterprises in Myanmar typically adopt only a few modern business practices, and the persistence in the use is extremely low. Even so, we find a positive and economically important association between business practices and productivity. Specifically, the empirical results show that a one standard deviation difference in applied business practices (equivalent to applying an additional 4 to 5 of the 20 business practices in focus) is associated with an 8–10 per cent difference in labour productivity. Utilising the employer–employee information to estimate Mincer-type wage regressions, we find that workers receive about half to two-thirds of the productivity gain in higher wages. Overall, our findings support the notion of business practices as a production technology, and we find that workers and managers split the productivity gains evenly.

LINKING DISSOLVED ORGANIC CARBON SPATIAL HETEROGENEITY TO GROUNDWATER DYNAMICS AND SOIL ORGANIC CARBON CONTENT IN A SUBTROPICAL HEADWATER CATCHMENT

Storage and fluxes of dissolved organic carbon (DOC) are triggered by interactions between hydrological and biogeochemical processes in the landscape. However, the relationship between DOC sources and catchment water storage is poorly understood due to uncertainties about the interactions between shallow groundwater (GW) dynamics and soil organic carbon (SOC). To investigate the relationships between catchment functioning and the spatiotemporal variability of DOC concentrations in shallow GW, we monitored a network of 12 shallow GW wells in a 0.24 km² catchment in Southern Brazil using DOC analysis and SOC measurements together with GW and stream gauging and statistical analyses. The greatest DOC concentration was observed in wells in the zero-order basin with highly dynamic saturation of the soil profile (50% with water table level below 0.5 m, mean DOC = 4.83 ± 2.53 mg L -1 ), where GW was characterized by a fast rise and slow decay during storm events. In these areas, the relationship between DOC concentration and GW level followed a decay with soil depth and higher DOC concentrations were found when GW level was within 0.1 m of the soil surface (ranging from 2.00 to 14.8 mg L -1 ). Wells in mid-slope locations were characterized by the lowest SOC content and DOC concentration in GW (1.96 ± 0.91 mg L -1 ). During the driest period, lower slopes showed higher DOC concentrations than riparian zones due to the persistent near saturation of GW and the occurrence of DOC-enriched water due to the high SOC content in superficial layers. When the riparian zone and hillslopes showed a low water storage deficit and a quasi-permanent hydrological connectivity, DOC produced between rainfall events was transported continuously from saturated areas in hillslopes to riparian zones, with a higher DOC concentration in wells near streams. This study demonstrates that spatial sources of DOC in a subtropical headwater system are linked to streamflow generation processes and GW dynamics.
Adaptive Power Point Tracking Control of PV System for Primary Frequency Regulation of AC Microgrid With High PV Integration

With the increasing integration of PV generation in AC microgrids, it is challenging to keep the stability of system frequency due to the intermittent and stochastic nature of PVs. Thus, in order to reduce the investment and maintenance costs of storage systems, the electric utility has shown increasing interest in calling on PVs to provide frequency regulation services. In this paper, a novel sliding mode control (SMC) based adaptive power point tracking (APPT) control strategy is proposed to provide bi-directional primary frequency regulation (BPFR) of an AC microgrid. In this strategy, in order to restrain the variation of frequency, the sliding mode surface is adaptively regulated to provide an adaptive power reserve. Thus, the PVs will have a power headroom to regulate the frequency both up and down through releasing the reserved power or increasing the reserves of the PV systems. Furthermore, the sliding mode surface is adaptively regulated only based on the locally measured frequency of the microgrid without the requirements of communication, detailed PV model, irradiance sensors as well as MPP estimators. Thus, the proposed control strategy shows the advantages of easy to implement and reduces the investment and maintenance costs of installing storage systems or irradiance sensors.
Learning Methods and Motivation Towards Learning Outcomes of Soccer Games

This research is motivated by the results of a survey conducted at school showing that students who play soccer still have a lot of low playing football skills. Both in terms of dribbling, passing, shooting, ball control. The role of motivation in learning can be likened to fuel to move students so that they are adequate and encourage students to learn seriously so that the expected goals can be achieved. This study uses an experimental research method with a 3x2 factorial design. The sampling technique in this study used purposive sampling technique, the research sample amounted to 72 people. The instruments used were heading, passing, dribbling, and shooting skills. The results of the study show that the TGT type of Cooperative method is better in improving the results of football skills compared to the STAD and Jigsaw methods. It is recommended to improve soccer skills at the Senior High School level to use the TGT type Cooperative method.
The Potential of Biophilic Fractal Designs to Promote Health and Performance: A Review of Experiments and Applications

Fractal objects are prevalent in natural scenery. Their repetition of patterns at increasingly fine magnifications creates a rich complexity. Fractals displaying mid-range complexity are the most common and include trees, clouds, and mountains. The “fractal fluency” model states that human vision has adapted to process these mid-range fractals with ease. I will first discuss fractal fluency and demonstrate how it enhances the observer’s visual capabilities by focusing on experiments that have important practical consequences for improving the built environment. These enhanced capabilities generate an aesthetic experience and physiological stress reduction. I will discuss strategies for integrating fractals into building designs to induce positive impacts on the observer. Examples include fractal solar panels, fractal window shades, and fractal floor patterns. These applications of fractal fluency represent a fundamental and potentially impactful form of salutogenesis.
Effects of Manual, Cultural, Botanical and Chemical Treatments of Termite Control in Hamelmalo Agricultural College Area

Termites are the most serious pests of field and horticultural crops, forests, and wooden household furniture. In Hamelmalo Agricultural College (HAC) the infestation of termite is very high resulting in great destruction of crop plants and wooden office and dormitory furniture. The devastating attack of termites should be managed by using best and ecofriendly management method. The purpose of the study was to compare the effectiveness of manual destruction of mounds and killing of termite queen and king, chemical chlorpyrifos, seed and leaves extract of neem and Lantana (as separate experiment) and smoke on termite control. Termite mounds were selected randomly inside HAC compound. The materials used were hand hoe, spade, fork, water, 20 L jar and protective clothes. The treatments were replicated three times. The botanical treatments were prepared at 2 L of highly concentrated extracts per 20 L of water each. Chlorpyrifos was applied at 20 ml per 20 L of water. Dried woody plants were used for smoke treatment. Careful digging was done to avoid king escape and queen rupture and they were killed by burning. Among all, the mechanical destruction and killing of king and queen and chlorpyrifos resulted in a complete control of the termite population. Except in the mounds treated by chlorpyrifos, the activity of termite population was very active and they closed the opened galleries immediately after treatment even though there were dead termite castes in all treatments. Living termite castes were counted by taking a medium size spade of broken mound pieces. The highest count was recorded from mounds treated by smoke. After two weeks the queen and king in every treatment mound were cheeked and killed for those who were alive. Except by the chlorpyrifos and manual destruction of mound (king and queen were killed before) all the royal families were alive and killed. Controlling of termite population in the field (outside their mound) is not possible due to the hidden foraging activity of termites, environmental safety from chemicals and the high egg laying potential of the queen. Finding the best alternative to control from their source mound for the mound building termites resulted in effective control of the population by manual destruction of mounds and killing of queen and king and chlorpyrifos. By the side effect of chlorpyrifos to untargeted organisms and the time consuming and laborious method of manual destruction of mounds, selection to the best from these two control measure is almost the same.
Water-soluble Cation Contents of ‘Jonathan’ Apple Fruit Pulp as an Estimation of Total Content

A method was developed to determine the total Ca, Mg, and K content of apple (Malus domestica Borkh.) pulp based on an assay in the water-extractable fraction. Water-soluble and total levels of each of the three elements in the fruit correlated significantly (P < 0.001) at harvest. The method is accurate (cv = 4.1%, 4.1%, and 2.5% for Ca, Mg, and K, respectively) and time-saving. The total level of minerals determined by the method proposed correlated well (P < 0.001) with that obtained by acid digestion of freeze-dried apple pulp.
