A case of prolonged corneal sulfur foreign bodies and review of literature

BackgroundThis case mainly describes a relatively rare case of an old mineral-like corneal foreign body that existed for up to 20 years, and did not significantly affect the visual quality of the patient.Case presentationA 56-year-old male miner complained of right eye vision loss for 3 years, swollen and painful for 4 months. Admission examination: Best corrected visual acuity was no light perception in the right eye and 20/20 in the left eye. Anterior segment examination: A large number of spot-like grayish-brown mineral foreign bodies in the conjunctiva of the nasal conjunctiva, emulsified silicone oil floating in the anterior chamber, Corneal foreign bodies in the right eye were widely distributed in the upper cortex and the proelastic layer. There were fewer foreign bodies in the left cornea. Previous medical history, 20 years ago due to forging and burning sulphur mine explosion, resulting in a large number of ore foreign bodies in the conjunctiva of both eyes. As these corneal foreign bodies did not affect the visual quality of the patient, we adopted a conservative treatment plan, did not remove these foreign bodies, and only carried out symptomatic treatment for the patient’s secondary ocular hypertension. The patient was followed up normally in the outpatient department, and no cornea-related complications occurred up to now.ConclusionsFirst of all, it is necessary to understand the source and nature of the foreign body in patients with corneal and conjunctival foreign body injuries. In the second, for the old corneal metal foreign body, when the patient’s visual acuity is stable and there are no symptoms of corneal irritation and inflammatory reaction, it can be Conservative treatment or outpatient follow-up observation. In the end, corneal Optical coherence tomography imaging should not be ignored, which is very important for determining the depth of embedding and the location of the corneal foreign body.

Hierarchical syntax model of music predicts theta power during music listening

Linguistic research showed that the depth of syntactic embedding is reflected in brain theta power. Here, we test whether this also extends to non-linguistic stimuli, specifically music. We used a hierarchical model of musical syntax to continuously quantify two types of expert-annotated harmonic dependencies throughout a piece of Western classical music: prolongation and preparation. Prolongations can roughly be understood as a musical analogue to linguistic coordination between constituents that share the same function (e.g., ‘pizza’ and ‘pasta’ in ‘I ate pizza and pasta’). Preparation refers to the dependency between two harmonies whereby the first implies a resolution towards the second (e.g., dominant towards tonic; similar to how the adjective implies the presence of a noun in ‘I like spicy … ’). Source reconstructed MEG data of sixty-five participants listening to the musical piece was then analysed. We used Bayesian Mixed Effects models to predict theta envelope in the brain, using the number of open prolongation and preparation dependencies as predictors whilst controlling for audio envelope. We observed that prolongation and preparation both carry independent and distinguishable predictive value for theta band fluctuation in key linguistic areas such as the Angular, Superior Temporal, and Heschl's Gyri, or their right-lateralised homologues, with preparation showing additional predictive value for areas associated with the reward system and prediction. Musical expertise further mediated these effects in language-related brain areas. Results show that predictions of precisely formalised music-theoretical models are reflected in the brain activity of listeners which furthers our understanding of the perception and cognition of musical structure.

Bilateral Direct Investment and Global Value Chain Climbing

According to the spirit of the 20th National Congress report, China should not only adhere to the depth of embedding in the global value chain, but also enhance the height of embedding in the global value chain. Therefore, China should actively explore and develop towards the high-end of the value chain. This article aims to explore the relationship between two-way direct investment and the climb of the global value chain. According to the research results, two-way direct investment can promote economic development through multiple mechanisms and further achieve China's climb in the global value chain. Currently and even in the future, we need to further strengthen policy coordination, optimize the investment environment, improve the efficiency and quality of two-way investment, in order to promote the global value chain to a higher level.

Experimental investigations the effects of dusty, humidity and temperature conditions on chemical anchors

Chemical anchor applications are frequently used to add new structural elements to existing structures. Chemical anchors can be applied quickly and easily, if anchors apply according to a detailed installation and cleaning procedure depending on environmental conditions and workmanship. In this work, the relationship between the axial tensile capacity of chemical anchors and the effect of dust, humidity, and temperature were examined as adverse conditions. The effect of using different conditions, anchorage diameters and embedment depth on the tensile strength of the anchors was evaluated. In the experimental study, anchors diameter 12, 16 and 20 mm were selected to be used as anchors. The depth of embedding was determined to be 5, 10, 15 and 20 times the diameter of used anchors. The initial stiffness, displacement ductility ratio, energy absorption capacity, failure modes, and safety levels according to ACI 318 were obtained by using the load-displacement curves. According to the parameters considered in the experimental program, the most unfavorable situation was obtained in anchors embedded in a wet environment. In addition, it was observed that the diameter of the drilled holes causes a decrease in the axial tensile capacity by increasing the exposure time of the anchors to water and temperature.

Environmentally friendly material for the construction of pile foundations on permafrost

Modern construction of pile foundations in permafrost conditions includes a cycle of operations: conducting geological and geodesic surveys; developing design and estimate documentation; construction and installation work; monitoring. Six main indicators are considered to determine the organizational and technological reliability of pile foundations for industrial tanks in permafrost soils: environmental performance (EF), intensity (Cf), cost (Cf), innovation (Mf), operational reliability (ORf), quality (Qf). Eco-friendliness depends on the material, the immersion technology, embedding depth, engineering and environmental survey, and other factors. Quality depends on determining the characteristics of the soil, assessing the depth of the hard frozen ground, methods for analyzing the strength characteristics of piles, pile inspection methods, materials, sinking technology, and other factors. The intensity depends on the volume and duration of the work. The duration depends on the depth of the foundation, pile installation technology, climatic conditions, soil characteristics, and other factors. The cost depends on the depth of embedding, immersion technology, material, construction area, the complexity of the project, and other factors. Innovativeness depends on introducing new technologies, resistance to climate change, material, structural changes in piles, and other factors. Operational reliability depends on permafrost soil characteristics, foundation design parameters, material performance characteristics, process parameters, operating conditions, inspection and maintenance, and other factors.

Investigation and substantiation of the parameters of the plow body angle lift

Currently plowing fields from under various agricultural crops is carried out with reverse plows in Uzbekistan. Their use can dramatically reduce labor and money costs for conducting current and capital field planning. With the supply of energy-rich wheeled tractors to the Republic of Uzbekistan, one of the most effective ways to increase the productivity of plowing units at present is to increase the plow's working width by increasing the number of housings. Increasing the number of hulls on revolving ploughs, equipped with pre-ploughs, this leads to a sharp increase in the metal and energy consumption of ploughs, since the latter have a double number of working elements. Therefore, an important role is played by the optimal placement of plow bodies along the plow course and the maximum reduction of distances between them, when using angle plates on the bodies instead of traditional pre-plows. The article discusses experimental influence of the angle-lift radius of curvature, the installation height, and the installation angles in the longitudinally-vertical and transversely-vertical planes on the traction resistance of the hull and the depth of embedding of plant remains was studied by MRI.

Key words: miscanthus, mass of rhizomes, planting density, fertilizers, productivity, proftability.

Talent Flow Network, the Life Cycle of Firms, and Their Innovations.

This paper explores how talent flow network and the firm life cycle affect the innovative performances of firms. We first established an interorganizational talent flow network with the occupational mobility data available from the public resumes on LinkedIn China. Thereafter, this information was combined with the financial data of China’s listed companies to develop a unique dataset for the time period between 2000 and 2015. The empirical results indicate the following: (1) The breadth and depth of firms’ embedding in the talent flow network positively impact their innovative performances; (2) Younger firms’ innovations are mostly promoted by the breadth of network embedding, but this positive effect weakens as firms increase in age; (3) Mature firms’ innovations are primarily driven by the depth of network embedding, and this positive effect strengthens as firms increase in age. This paper enriches and deepens the studies of talent flow networks, and it provides practical implications for innovation management based on talent flow for various types of firms at different development stages.

Classification of Infilled Shells Structures Considering Soil-Construction Interaction

The paper examines retaining structures consisting of thin shells filled with soil or other material (in a varying degree providing structural integrity), keeping the soil from failure and sustaining the complex of technological loads. Filled shells structures serve as a constructive base for retaining structures and are used in various construction areas (industrial, transport, hydraulic engineering). The technique is proposed which allows to determine structural design model at an early design stage considering the key initial design parameters: overall dimensions of the structure, acting loads and the soil base properties. Based on the proposed ratios an example is given of the structure classification and the design model choice depending on its dimensions, depth of embedding and the magnitude of soil base design resistance. Extreme principal dimensions ratios of the structure are shown at which there is a need of fixing the structure in the soil, dependencies for determining setting depth are given.

ЕКСПЕРИМЕНТАЛЬНІ ДОСЛІДЖЕННЯ ПЛУГА З ДИСКОВИМ ПОДРІБНЮВАЧЕМ

Studies were conducted on the operation of a plow with a disk disintegrator in a unit with an MTZ-82 tractor on black soil with a flat relief on soybean stubble with the amount of plant residues from 300 to 400 g/m2. During the research, the following parameters were changed: the disk approach angle, the disk section installation height, and the tractor speed. As a result of the study, it was found that at the speed of a plow with a disk disintegrator from 4 to 5 km/h, the depth of plant residues embedding is maximum and ranges from 15 to 19 cm, while fuel consumption becomes minimal in the range from 18 to 30 kg/ha.

Possessive pronouns, Condition C and Anti-Cataphora Effects

This presentation addresses the following research questions: (a) does Binding Condition C, prohibiting pronouns from occupying positions c-commanding coindexed names, operate in the same manner in the grammars of English and Polish (Slavic)? (b) why do possessive pronouns in Slavic languages cause an effect similar to Condition C?, and (c) which syntactic relation is responsible for the Anti-Cataphora Effect (ACE)? The question of why Condition C does not subsume the Anti-Cataphora Effect is addressed in detail and it is shown to what extent pronominal possessives in Polish and English occupy different structural positions. Other structural factors that influence the ACE are also analysed, such as the depth of embedding of the possessive, the grammatical function of the NP containing the possessive (subject vs. object), the distance between the proximate possessive and the coindexed name and intervention by other possessive NPs. Current theory of syntax relies on two basic structural relations driving morpho-syntacic operations: Agree and Move (Chomsky, 2000, 2001, 2008, 2013). In the context of the ACE, both of these relations will be tested for their accuracy in licensing this effect. In prominent recent accounts (La Terza, 2016; Franks, 2019) the ACE results from movement of the proximate possessive pronoun to some position from which it c-commands the coindexed name. It is argued below that the ACE is rather caused by an instantiation of Agree which presupposes little movement on the part of the proximate possessive.

Numerical analysis of the performance of pile cap on a single pile for a lateral bearing capacity in layered soil

Deep underground infrastructure is booming technology in developing countries, and these construction techniques are mostly used in developed countries at present. Pile foundation among many types of deep structures, it is significantly researched and built to sustain and transfer loads from superstructures to deep soil, in either case, the load from the superstructure is very high or the soil at shallow depth is too weak. Piles are subjected to axial, horizontal, momentary, and combined loading systems as a single pile or pile group system connected to the reinforced pile cap on top of the pile to share or transfer loads through the wall and tip to the surrounding soil. Along with elastic solid pile-pile cap characteristics of materials, a limited number of numerical and analytical studies are published even merely on a homogeneous soil placement of the pile cap model. However, The soil’s natural deposit at a significant site may not always be found homogeneous on which pile-caps and piles are placed. To fill the gap of an intricated multi-physics soil-structure interaction problems, successive analysis is incurred to be proliferated. The study presented a numerical analysis of the influence of the pile cap on the single laterally loaded pile, while the embedding of the pile cap varied on the layered soil profile. The standard linear static numerical analysis software ABAQUS was used to model 3D pile cap-pile and layered soil with subjected lateral load and relevant boundary conditions. The result of the analysis was plotted varying the embedding of the pile cap on clay overlaid sand and sand overlaid clay interchangeably taking into consideration other influencing parameters (pile capsize and vertical load). The increase in pile cap embedment on clay overlaid sand slightly increases the lateral resistance of the pile cap for the first few increments and small non-linear variation for further embedding from the analysis has resulted. However, the performance of the pile cap for lateral load resistance was significantly increased as the depth of embedding of the pile cap is increased on sand overlaid clay. Besides, the size of the pile cap has a direct proportion for lateral resistance, and the vertical load exerted on a pile cap has not had a significant influence. The study comprehensively emphasized the interaction of piles with simple soil physics problems, but multi-soil physics problems with pile interaction should be analyzed for future study.

Improving the energy efficiency of buildings based on the use of integrated solar wall panels

Frequently used facade glazing makes it possible, on the basis of modern trends in the architecture, to increase the energy efficiency of buildings under construction through the organization of passive solar heat supply. Despite the noted relatively low efficiency of the radiation utilization method recommended for the use, it is possible to increase its indicators by integrating the elements of active solar units in the absorbing layer of the accumulating construction structure. For example, the placement of pipes for the coolant in external enclosing structures will allow year-round exploitation of arrays for passive utilization of solar energy and the use of the obtained heat not only for heating rooms during the cold period of the year, but also for heating water, as well as for absorption chillers in the summer season. The application of the latter contributes to the organization of alternative cooling of the internal blocks of air conditioning systems in the warm period of the year. The listed functions require a different approach in the algorithm of the decisions taken in the design of building structures actively involved in the balance of energy supply. One of the main indicators that determine the possible version of the implementation of the solar radiation utilization system is the achieved temperature potential of the heat flux obtained from the surface of the accumulating layer. The use of the method of sources and the principle of the imposition of fields when solving problems of the depth of embedding and step distance integrated into the surface layer of pipes allows determining the rational range of the values of the specified parameters. This, in turn, is aimed at ensuring the possibility of designing energy-efficient exterior enclosing structures that contribute to the maintenance of the thermal regime required by the multifunctional utilization of solar energy.

Discussion: determining the optimal values of the frequency domain range and the depth of embedding of the marker require further experimental studies.

Neural Network Prediction of Daily Relativistic Electrons Fluence in the Outer Radiation Belt of the Earth: Selection of Delay Embedding Method

Prediction of the time series of relativistic electrons fluence in the outer radiation belt of the Earth encounters problems caused by complexity and non-linearity of the “solar wind – the Earth’s magnetosphere” system. Artificial neural networks are a biologically inspired architecture that is a suitable tool to solve problems of such type. This study considers the dependence of the quality of prediction on the type and depth of delay embedding of input features.

Experimental investigation of behaviour and failure modes of chemical anchorages bonded to concrete

In this study, the effect of using different adhesive types, anchorage diameters and embedment depth on the tensile strength of the anchors were evaluated. In the experimental work, concrete blocks on which the anchor was embedded were unreinforced and had a compressive strength of 25MPa. The ribbed construction iron bars with 12, 16, 20 and 24mm diameter were selected to be used as anchors. The depth of embedding is determined to be 5, 10, 15 and 20 times the diameter of the used anchors. The holes, to which the anchors were embedded, were 4mm larger than the anchor’s diameter. 10 different types of chemical adhesives were used in the study. These adhesives are based on 4 epoxy, 3 polyster, 2 epoxy acrylics and 1 vinylester. By using the load-displacement graphs obtained from this study, axial load capacity, failure modes, initial stiffness, displacement ductility ratios and energy dissipation capacities were calculated and important conclusions were obtained from discussing the experimental results regarding the general performances of anchors. Also, capacity and design strength of anchors were calculated according to ACI 318 (2008). As a result, the effect of the chemical adhesive usage on the anchors performance was evident in the anchors with diameters of 16, 20 and 24mm while, at small diameters, the effect wasn’t clear also the best durability was obtained when using epoxy-based adhesives, and the ideal embedding depth was 16mm for 10Ф anchors and 20 and 24mm for 15–20Ф anchors.

Comparison of Ultrasonic Welding and Thermal Bonding for the Integration of Thin Film Metal Electrodes in Injection Molded Polymeric Lab-on-Chip Systems for Electrochemistry.

We compare ultrasonic welding (UW) and thermal bonding (TB) for the integration of embedded thin-film gold electrodes for electrochemical applications in injection molded (IM) microfluidic chips. The UW bonded chips showed a significantly superior electrochemical performance compared to the ones obtained using TB. Parameters such as metal thickness of electrodes, depth of electrode embedding, delivered power, and height of energy directors (for UW), as well as pressure and temperature (for TB), were systematically studied to evaluate the two bonding methods and requirements for optimal electrochemical performance. The presented technology is intended for easy and effective integration of polymeric Lab-on-Chip systems to encourage their use in research, commercialization and education.

Molecular interactions with ice: molecular embedding, adsorption, detection, and release.

The interaction of atomic and molecular species with water and ice is of fundamental importance for chemistry. In a previous series of publications, we demonstrated that translational energy activates the embedding of Xe and Kr atoms in the near surface region of ice surfaces. In this paper, we show that inert molecular species may be absorbed in a similar fashion. We also revisit Xe embedding, and further probe the nature of the absorption into the selvedge. CF4 molecules with high translational energies (≥3 eV) were observed to embed in amorphous solid water. Just as with Xe, the initial adsorption rate is strongly activated by translational energy, but the CF4 embedding probability is much less than for Xe. In addition, a larger molecule, SF6, did not embed at the same translational energies that both CF4 and Xe embedded. The embedding rate for a given energy thus goes in the order Xe > CF4 > SF6. We do not have as much data for Kr, but it appears to have a rate that is between that of Xe and CF4. Tentatively, this order suggests that for Xe and CF4, which have similar van der Waals radii, the momentum is the key factor in determining whether the incident atom or molecule can penetrate deeply enough below the surface to embed. The more massive SF6 molecule also has a larger van der Waals radius, which appears to prevent it from stably embedding in the selvedge. We also determined that the maximum depth of embedding is less than the equivalent of four layers of hexagonal ice, while some of the atoms just below the ice surface can escape before ice desorption begins. These results show that energetic ballistic embedding in ice is a general phenomenon, and represents a significant new channel by which incident species can be trapped under conditions where they would otherwise not be bound stably as surface adsorbates. These findings have implications for many fields including environmental science, trace gas collection and release, and the chemical composition of astrophysical icy bodies in space.

New two-dimensional polymer-metal composites based on highly ordered ensembles of nanoparticles. Design and optical properties

A new method has been proposed for designing composite materials that represent highly ordered two-dimensional metal nanoparticles ensembles having variable geometric parameters and being embedded into the surface layer of a polymer matrix to a predetermined depth. The method is based on diblock copolymer micellar lithography and the effect of decreased glass-transition temperature of a polymer surface as compared with its bulk value. The possibility of independent variations in the depth of embedding of metal nanoparticles (by system annealing) and their size (by seeded growth) has resulted in the systematic study of the influence of the temperature and time of annealing on the kinetics of nanoparticle embedding into a polymer. For the first time, the plasmon-resonant properties of hexagonally ordered ensembles of gold nanoparticles located at a polymer-air interface have been experimentally studied. It has been established that the embedding of an ensemble of nanoparticles into a polymer is accompanied by a bathochromic shift of the maximum of its localized surface plasmon resonance due to a growth in the effective dielectric permittivity of the environment of the nanoparticles. An empirical equation has been proposed, which satisfactorily describes these experimental data.
