Abstract:

Freezing of the water confined in thin pores can be destructive to the porous frame, but the effect of the quasi-liquid layer (QLL) between the confined ice and the pore walls remains still far from being fully understood. In the present study, the physical origins of the intermediate phase of QLL were discussed by thermodynamic analyses. Different interactions on QLL bring different models to estimate its thickness, which generally decays with temperature decreasing. Four representative models of QLL thickness were selected to unveil its effect on the growing rates and extents of ice in a concrete. The engineering consequences of the confined freezing were then discussed in the aspects of effective pore pressures built from the confined ice growth and deformations framed by a poro-elastic model. Overall, thickening QLL depresses ice growing rates and contents and, consequentially, decreases pore pressures and material deformations during freezing. The QLL corrections also narrow the gaps between the predicted and measured freezing deformations. The findings of this study contribute to profound understandings of confined freezing that may bridge over physical principles and engineering observations.

Abstract:

Frame structure building is widely used for its advantages of flexible space, light weight, saving material, building plan can be flexibly arranged and so on. However, researches on frame structure built in the water in cold areas, under horizontal ice pressure, are very few, and there is also no ice pressure calculation method for this structure form. Combining with the damage phenomenon of Jintaizi fishing floor engineering, analyzed the causes of freezing damage from ice pressure, temperature joint, structure form, and put forward a concept of ice pressure influence width for frame structure under the effect of ice. This article provides a reference for ice pressure calculation and the design of frame structure buildings which built in the water.

Abstract:

In this paper we present a novel no-reference video quality measure, NR-FFM (no-reference frame–freezing measure), designed to estimate quality degradations caused by frame freezing of streamed video. The performance of the measure was evaluated using 40 degraded video sequences from the laboratory for image and video engineering (LIVE) mobile database. Proposed quality measure can be used in different scenarios such as mobile video transmission by itself or in combination with other quality measures. These two types of applications were presented and studied together with considerations on relevant normalization issues. The results showed promising correlation values between the user assigned quality and the estimated quality scores.

Abstract:

The article presents the experience of constructing buildings on surface foundations in winter season. Within the frames of the investigation, there were evaluated temperatures in the base composed of heaving soils, as well as foundation displacements during the winter period. There have been were performed calculations of temperature fields and soil heaving deformation using the Termoground program. It is shown that despite the relatively big depth of the base soil freezing, the maximum displacements of the foundations did not exceed 7 mm, which is quite acceptable for a frame building.

Abstract:

The melting and freezing with two different cooling rates of AgN (N= 140, 360, 532, 784, and 952) nanoclusters are simulated by using molecular dynamics technique with the frame work of embedded atom method. The potential energy as a function of temperature is obtained and the structural details are analyzed. The results reveal that the melting and freezing temperature increases almost linearly with the atom number of the clusters except for Ag360. All the silver nanoclusters have negative heat capacity around the phase transition temperature, and the clusters with slow cooling rate have icosahedral structure at 300 K.

Abstract:

PurposeThis paper aims to examine the media coverage of a new reproductive benefit (oocyte cryopreservation) made available to employees at Apple and Facebook in 2014, in light of an ongoing public debate around the conflict experienced by women to be both “ideal workers” and “ideal mothers”.Design/methodology/approachThe study examines the coverage of the new benefit as a news item in major American newspapers and websites. It uses problem/solution frame analysis and provides a qualitative analysis of the leads, journalists’ rhetoric and sources found in 23 news articles on the topic. A rudimentary quantitative analysis of positive and negative solution evaluations is also included.FindingsAll the articles were found to use a problem/solution frame in their presentation of the new benefit as a news item. When biology is presented as at the root of the motherhood/career conflict, as it was by many journalists and their chosen sources, this logically leads to a biotechnological solution, such as egg-freezing. Other potential contributors to motherhood/career conflict, such as rigid and gendered career timelines and inadequate supports for working parents, are largely left out of the discussion – as are potential broader workplace and socio-cultural changes.Research limitations/implicationsThis study was limited to news articles only; the coverage of the issue in opinion pieces and in other media might have different findings. An experimentally designed study might lead to interesting findings on the impact of these framing elements (leads, rhetoric, sources) on readers’ responses to this topic.Originality/valueThis study contributes to research on the media coverage of motherhood and to management scholarship on gender, parenthood and work.

Abstract:

Frame used in XX inertial navigation system has such characters as small scale, thin wall, complicated shape, etc. When it is casted by gravity casting, the defects such as shrinkage, porosity and blow holes are so many that the survival ratio is very low. In this paper, a new differential pressure casting method is designed to cast the frame by realizing self-hardening sand moulding, solving series of problems such as liquid rising pipe freezing and chemical composition being out of range, thus improving the quality of the cast.

In Field guides to exceptionally exposed carbonate outcrops, 265–309. International Association of Sedimentologists, 2021. http://dx.doi.org/10.54780/iasfg3/06.

Full text

Abstract:

The goal of the field itinerary is to illustrate the facies and architecture of a Triassic high-relief carbonate platform (lithostratigraphically known as Esino Limestone; Lombardy, N Italy), similar in age and evolution to the more renowned coeval carbonate platforms of the Dolomites (NE Italy) and the coeval basinal facies. In the central Southern Alps dolomitization is less pervasive with respect to the Dolomites, so that the facies preservation is spectacular, allowing for the observation of detailed depositional and diagenetic features. Furthermore, the visited platform outcrops provide the unique opportunity to observe the sedimentological record of its demise, freezing the architecture of a platform that lasted for about 5 Myr (from close to the Anisian-Ladinian boundary to the Ladinian-Carnian boundary), from the platform top to the basin. The complete section of this Ladinian-Carnian (Middle-Upper Triassic) high-relief carbonate platform is exposed along the Brembana Valley, north of the city of Bergamo. Facies types can be observed in selected outcrops during the field trip, whereas seismic scale geometric and stratigraphic relationships (from the platform top to the slope and basinal setting), can be observed from selected viewpoints. The carbonate platform system reaches a thickness of up to 800 m, with a platform-basin relief of more than 600 m at the end of its evolution. The field itinerary crosses the entire system, from the inner platform to the basin, of one of the best-preserved Triassic carbonate platforms of the Southern Alps of Italy. Inner platform (subtidal to peritidal cycles consisting of oncoidal-bioclastic packstone to grainstone capped by stromatolitic beds), reef (mostly microbial boundstone), slope (clast-supported, early-cemented poorly-selected breccias produced by collapses of the reef-upper slope belt) and basinal facies (dark, well-bedded limestone) facies are exposed in the visited outcrops. During a ‘geological dive’, from the platform top to the basin floor, the diverse subenvironments of the carbonate system can be observed, appreciating the variability of facies along the depositional profile. Each observation is framed in the seismic-scale geometry of the platform that can be appreciated from easily accessible viewpoints. The exceptionally well-preserved facies, as the facies-destructive dolomitization that heavily affects the spectacular coeval platforms of the Dolomites is here rare, permit to document in detail the depositional, early and late diagenetic events. The visited high-relief carbonate system is characterised by a rapid demise, recorded by changes in the facies associations that are exposed in some of the stops representative of different depositional environments: platform top, reef and slope. The abrupt demise of this carbonate system is marked by a major (probably earliest Carnian) sea-level fall associated with a climate change recorded in the different parts of the depositional system by major facies changes. On the platform top the demise is marked by regressive carbonate facies that have different sedimentological characteristics and thickness in the inner platform and in the reef belt. In the basin and on the slope the demise of the carbonate platform is associated with the abrupt input of clay in the basinal setting facing the progradational platform: the seismic-scale onlap relationships between the last prograding clinoform of the Esino Limestone (clast-supported breccias) and the overlying basinal clay can be observed in a spectacular outcrop along the platform slope.

Abstract:

A mathematical model for phase change heat transfer in cryosurgery was established. In this model, a fractal tree-like branched network was used to describe the complicated geometrical frame of blood vessel. The temperature distribution and ice crystal growth process in biological tissue including normal tissue and tumor embedded with two cryoprobes were numerically simulated. The effects of cooling rate, initial temperature and distance of two cryoprobes on freezing process of tissue were also studied. The results show that the ice crystal grows more rapidly in the initial freezing stage and then slows down in the following process, and the pre-cooling of cryoprobes has no obvious effect on freezing rate of tissue. It also can be seen that the distance of 10 mm between two cryoprobes is the most appropriate choice for operation effect in the range of operating conditions presented in this study.

Abstract:

An unsteady, three dimensional Navier-Stokes solution in rotating frame formulation for turbomachinery applications has been described. Casting the governing equations in a rotating frame enables the freezing of grid motion and results in substantial savings in computer time. Heat transfer to a gas turbine blade was computationally simulated by finite element methods and probabilistically evaluated in view of the several uncertainties in the performance parameters. The interconnection between the CFD code and finite element structural analysis code was necessary to couple the thermal profiles with the structural design. The stresses and their variations were evaluated at critical points on the turbine blade. Cumulative distribution functions and sensitivity factors were computed for stresses due to the aerodynamic, geometric, material and thermal random variables. These results can be used to quickly identify the most critical design variables in order to optimize the design and make it cost effective. The analysis leads to the selection of the appropriate materials to be used and to the identification of both the most critical measurements and parameters.

Full text

Abstract:

In the last decade, there has been an increased focus and interest in increasing the utilization of existing raw materials and reducing waste especially due to the increasing global population. In the cod filleting industry up to 60% (w/w) of the biomass end up as side-streams e.g., frame, head and gut, which are either used as low value products such as animal feed or are wasted. An example of animal feed is mink feed. However, in Denmark the mink production is closed due to COVID-19 and new utilization possibilities are needed. The cod side-stream used in this study is from Royal Greenland and is very fresh with the possibility of freezing right after production to maintain quality and increase shelf life before further production. Cod frames still contain meat after filleting and could be used as hydrolysates with bioactive properties such as antioxidative and/or antimicrobial activity for food or feed applications. Previous studies have shown that longer peptides (shorter hydrolysis time) potentially have antimicrobial properties and shorter peptides (longer hydrolysis time) have antioxidative properties. Therefore, an experiment was designed using three different types of proteases (Alcalase, Neutrase and Protamex) and different hydrolysis time (½h, 1, 2, 3 and 6h) to produce different hydrolysates. Produced hydrolysates were evaluated for their antioxidative and antimicrobial activities by in vitro antioxidant assay, radical scavenging (DPPH) and metal chelating activity, and by disc diffusion and minimal inhibitory concentration (MIC) assays, respectively. Furthermore, the hydrolysates were also characterized with respect to yield, protein content and degree of hydrolysis. The produced hydrolysates showed antioxidant properties. Highest DPPH activity was obtained with Protamex, where-as highest metal chelating activity surprisingly was obtained for a control (no enzyme added). Unfortunately, no antimicro-bial activity was detected for the produced hydrolysates independent of enzymes and hydrolysis time applied. BBI JU-funded WASEABI project.

Abstract:

This paper presents the design, selection of equipment, testing, and analysis of a 2 TPD (76 kg/hr) prototype oxygen liquefier that employs a mixed gas refrigeration cycle. Small scale oxygen plants (30–60 TPD) based on VPSA systems (Vapor Pressure Swing Adsorption) periodically require liquid back-up to provide uninterrupted supply of O2 gas to customers during planned plant maintenance. Supply of liquid for back-up, especially to customers in remote locations, is expensive and difficult. Economically designed MGR liquefiers will fulfill this market need. The 2 TPD prototype O2 liquefier is based on the dual loop MGR Rankine cycle (see Figure 1). The forecooler loop provides refrigeration at the warm end (233K). R507 is used as a refrigerant for the forecooler in the warm end loop. The main refrigeration loop uses a mixture of R218, R14 and N2. The main advantage of separating the refrigerants into two different loops is to avoid freezing of high boiling point refrigerants at liquid O2 temperatures in the main refrigeration loop. The process and mixture composition were optimized using the HYSYS process simulation package. Very useful insights were gained in terms of reducing the irreversibilities in the heat exchanger. Low cost innovative designs were adopted for the heat exchangers. For example: (1) plate-and-frame heat exchangers were successfully used for multiple gas streams, (ii) a spirally wound coiled heat exchanger was used to liquefy oxygen. Similarly, the compressors used in the forecooler and main cycle were low cost, off-the-shelf items used in conventional refrigeration systems. The liquefier unit was initially demonstrated and a liquid making capacity of 1.5 TPD at a unit power of 44 kW/TPD was achieved. Subsequent modifications to the heat exchangers resulted in meeting the design expectations at a unit power of 37 kW/TPD.
