Strategies to Reduce Salt Content: PDO and PGI Meat Products Case.

The reduction of sodium chloride (NaCl) content, commonly known as salt, in processed meat products is one of the objectives of health organizations and government authorities to achieve healthier products. This reformulation of traditional meat products with protected designations poses more constraints, as they have a more consolidated quality image and less margin for change, since consumers appreciate the products for their unique sensory characteristics. The aim of this work is to present some of the strategies that have been explored to obtain meat products with low sodium content. Information related to the characteristics of traditional meat products with quality marks and geographical indications in different studies is discussed in opposition to the information recorded in their product specifications. It was found that the product specifications of meat products with Portuguese Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) show a wide variation in the NaCl content, much higher than the recommended values. Thus, one of the requirements to be implemented will be the parameterization of NaCl levels and their monitorization by control and certification organizations as a way to ensure product quality. It is also urgent to examine whether healthy innovation strategies may affect the quality of traditional PDO or PGI meat products and whether they can be included in the respective product specifications.

A Novel Method to Assess Healing of Segmental Bone Defects using the Induced Membrane Technique.

Clinical concerns exist regarding the quality of bony consolidation in the context of the induced membrane technique. This study evaluates the clinical process of bone grafting in the second stage of induced membrane bone union in patients with tibial bone defects to infer the possibility of non-union and establish a reliable and effective evaluation method combined with computed tomography (CT) to assess fracture healing. Patients with tibial bone defects who underwent the induced membrane technique at our hospital between February 2017 and February 2020 were retrospectively analyzed. The Hounsfield unit (HU) values of the patients were evaluated at different times during the second stage of bone grafting. Bone healing at the boundary value of the 120 HU output threshold (-1024 HU-3071 HU) was directionally selected, and the changes in the growth volume of union (new bone volume [selected according to HU value]/bone defect volume) were compared with analyzing individual class bone union. Method 1 involved X-rays revealing that at least three of the four cortices were continuous and at least 2 mm thick, with the patient being pain free. For Method 2, new bone volume (selected according to HU value/bone defect volume) at the stage was compared with analyzing individual class healing. Receiver operating characteristic curve analysis was used for Methods 1 and 2. A total of 42 patients with a segmental bone defect with a mean age of 40.5 years (40.5 ± 8.3 years) were included. The relationship between bone graft volume and time variation was analyzed by single factor repeated variable analysis (F = 6.477, p = 0.016). Further, curve regression analysis showed that the change in bone graft volume over time presented a logarithmic curve pattern (Y = 0.563 + 0.086 × ln(X), Ra2 = 0.608, p = 0.041). ROC curve analysis showed that Method 2 is superior to Method 1 (AUC: 86.3% vs. 68.3%, p < 0.05). The induced membrane technique could be used to treat traumatic long bone defects, with fewer complications and a higher healing rate. The proposed imaging grading of HU (new bone volume/bone defect volume) can be used as a reference for the quality of bony consolidation with the induced membrane technique.

Comparison of limb reconstruction with vascularized fibula flap versus induced membrane technique in 54 pediatric cases over 16 years

BackgroundChildren's bone loss of limbs represents a significant challenge for surgeons, especially given that children are growing individuals. In the pediatric population, we compared bone reconstruction using vascularized fibula flaps with the induced membrane technique. The primary purpose of this study was to evaluate the delay and quality of consolidation. Methods.Data from patients who underwent limb reconstruction using either the fibula flap or the induced membrane were retrospectively collected from files across two centers. Perioperative and long-term complications were documented, along with functional and aesthetic outcome. ResultsBetween 2004 and 2020, 31 children underwent limb reconstruction using a fibula flap, and 13 patients were treated using the induced membrane technique. The etiologies included 76% tumors, 20% congenital pseudarthroses, and 3.7% infections. The median size of the bone resection was 12.5cm (range: 1.8 to 31cm). The median time to consolidation after free fibula flap transfer was 10 months (range: 2 to 55 months) versus 7.5 months (range: 1 to 64 months) for the Masquelet technique (p=0.54). Limb length inequality occured in 52% of fibula cases and 39% of the induced membrane cases (p=0.55). ConclusionsBoth of free fibula flap and the induced membrane technique are effective options for bone reconstructing long bones in children. These techniques yield good functional outcomes and have comparable consolidation times.

Direct consolidation of an oxide dispersion strengthened alloy by hot rotary swaging

AbstractSteels strengthened by alloying elements and precipitates typically maintain their enhanced properties up to the ferrite‐austenite transformation. However, oxide dispersion strengthened ferritic steels are creep resistant even at much higher temperatures given by dispersions of nanosized oxides. To ensure homogeneous dispersion of the oxides, powder metallurgy is used for preparation of the original material. The presented study investigates the effects of direct consolidation of powder of ferritic steel strengthened with yttrium oxide nanoparticles. The powders were mechanically alloyed and sealed into evacuated steel containers, which were subjected to gradual hot consolidation via the industrially applicable intensive plastic deformation method of rotary swaging. Investigations assessing the effects of several reduction ratios showed that the direct consolidation of the oxide dispersion strengthened steel was successful – in the macroscale – at the swaging ratio of 1.03; the quality of consolidation further increased with increasing swaging ratio. At the swaging ratio of 1.83, the consolidated bulk material featured ultra‐fine grains characterized with high angle grain boundaries, homogeneous dispersion of oxide precipitates, and the average Vickers microhardness of 706.6 HV 1.

Characteristics of in-situ automated fiber placement carbon-fiber-reinforced low-melt polyaryl ether ketone laminates part 2: Effect of prepreg composition

This paper presents an investigation into prepreg tape composition and its impact on the consolidation quality of in‐situ Automated Fiber Placement-manufactured laminates. Three different prepreg tape materials were investigated in terms of fiber distribution, porosity and surface roughness. Laminates were manufactured using the in-situ Automated Fiber Placement process and subsequently tested using microanalysis and mechanical testing methods. Higher quality prepreg tape material yielded lower porosity laminates and increased mechanical strength results. The best in-situ Automated Fiber Placement-manufactured laminates achieved 82 % and 88 % of hot-pressed reference tensile- and compressive strength, respectively. Prepreg tape with disadvantageous composition for in‐situ consolidation yielded up to 74 % knockdown compared to the best in-situ consolidated laminates. A five-point bending test was successfully used to determine interlaminar shear strength with significant results relating to consolidation quality. A correlation was successfully established between prepreg composition, resulting laminate consolidation quality and mechanical properties.

Optical properties optimization of carbon fiber reinforced thermoplastic tapes by micro surface texturing for enhanced laser heating efficiency and in-situ consolidation quality during AFP process

The laser-assisted automated fiber placement (L-AFP) process of carbon fiber-reinforced thermoplastic composites suffers from insufficient heating efficiency and in-situ consolidation quality caused by significant reflection on the tape surface. Here, we propose a novel strategy to increase the heating efficiency by refocusing the reflected light, initially scattered to the environment and wasted, onto the tapes for multiple and full absorptions. The method for laser concentration is first validated through light-tracing simulation. Then, three kinds of tapes with different micro textures on the surface are prepared by the hot-embossing process. The transverse V-grooved texture tapes and flat surface tapes absorb 25% more laser energy than the longitudinal V-grooved and commercial tapes due to the reduction in transverse scattering angle from 180° to 2.72°. This leads to a temperature increase of 130 °C at the nip point during the L-AFP process at the lay-down rate of 500 mm/s with 1 kW laser power. Improved in-situ consolidation quality leads to a significant increase in the flexural and shear strength of L-AFP-prepared carbon fiber reinforced polyetheretherketone (CF/PEEK) laminates, with a reduction in porosity to around 2%.

The article is devoted to the study of the didactic foundations of the organization of the stage of consolidation of socio-humanitarian knowledge by secondary school students in order to digestion them. Modern psychological and pedagogical approaches to the consideration of the essence of the process of memorization and consolidation of knowledge are presented and traditional and innovative techniques and methods of consolidating educational ma- terial are described as well. The publication contains a description of experimental work designed to improve the process of consolidating knowledge in the lessons of subjects of the socio-humanitarian cycle. The actual problem of conducting experimental work is determined as the identification of effective techniques and methods of consolidat- ing of socio-humanitarian knowledge, normatively fixed by general education programs. It was assumed that the solution of the presented problem would allow not only to determine the effectiveness of individual techniques and methods of consolidating socio-humanitarian knowledge, but also, in general, would allow for the solid assimilation of the program content in the practice of school education. The course of experimental work including the ascertain- ing, forming and control stages is described. The main project that was carried out at the formative stage consisted in the application of techniques and methods for consolidating socio-humanitarian knowledge of a reproducing na- ture as memorization, retelling, reproduction, and repetition. Productive nature contains conversation, observation, interaction with a textbook, performing exercises and tasks and associative-intellectual nature includes association of images, grouping of material into categories, the use of words that promote memorization, the use of schemes and the use of logical chains. The intermediate and final results of the experimental work are presented on the basis of the establishment of criteria and levels of determining the quality of consolidation of socio-humanitarian knowl- edge. The dynamics of improving the quality of knowledge consolidation is proved as a result of the application of techniques and methods of consolidation of a productive nature. The prospects of applying techniques and methods of fixing associative-intellectual character are recognized.

Role of the inter‐ply microstructure in the consolidation quality of high‐performance thermoplastic composites

AbstractConsolidation of Carbon Fiber (CF)/high‐performance thermoplastic composites is much less understood than the one of their thermoset counterparts. It is usually assumed that the consolidation quality is directly linked to the removal of voids within the sample during consolidation, leading to mechanical properties suitable for aerospace applications. A systematic study of the temporal evolution of CF/polyetherketoneketone (PEKK) samples' microstructure consolidated under low pressure in a rheometer is related to the increase in inter‐laminar shear strength. The results show that despite similar void contents well‐below 1 vol%, samples can present significant differences in ILSS values, from 80 to 95 MPa for cross‐ply samples, and from 98 to 112 MPa for unidirectional (UD) ones. A microstructural analysis shows that, for these materials, consolidation quality is rather related to a reorganization of the inter‐ply, a resin‐rich (~70 vol%) region of typical thickness 10 μm which is slowly repopulated in fibers during consolidation.Highlights Microstructure of CF/PEKK composites is characterized over consolidation time Contrary to thermosets void content cannot be used to predict mechanical properties ILSS increase over consolidation time is related to inter‐ply reorganization Inter‐ply microstructure and ILSS have a direct correlation The repopulation in fibers of the resin‐rich inter‐ply is a slow process

Development of microstructure and properties within oxide dispersion strengthened steel directly consolidated by hot rotary swaging

Steels strengthened with fine oxides maintain favourable mechanical properties at high temperatures. This unique study evaluates the effects of direct consolidation of mechanically alloyed powders of ferritic steel and Y2O3 nanooxides by hot rotary swaging (multiple swaging ratios) on microstrutcures and mechancial properties of final rods. Direct consolidation of the steel powder by the proposed method was successful at the swaging ratio 1.0. However, the quality of consolidation improved with increasing the swaging ratio to 1.4, and finally to 1.8 (no visible pores). The microstructure of the rod processed with swaging ratio 1.8 exhibited homogeneous dispersion of oxide particles and featured ultra-fine (UF) grains, its average Vickers microhardness exceeded 700 HV1.

Prediction of consolidation quality in laser-assisted AFP and effect of blank quality on stamp forming

This paper presents a parameter study into the thermoplastic-automated fibre placement process. The material used was carbon fibre-reinforced LM-PAEK unidirectional tape. The overall objective of this investigation was the derivation of regression models to describe and predict the consolidation quality of laminates in dependence on the main process parameters of the lay-up process. Furthermore, post-consolidation by stamp forming was investigated to analyse the impact of the initial quality of the blank on post-forming laminate quality. With the parameter study performed, prediction models for the degree of bonding and crystallinity could be derived. In addition, a more comprehensive understanding of the process parameter influences and the definition of parameter limits to distinguish between rapid and in situ lay-up processes was achieved. Furthermore, the potential of the process chain consisting of rapid lay-up and stamp forming for producing high-quality laminates was demonstrated for the investigated LM-PAEK tape.

Vacuum-bag-only consolidation of C/PEKK fiber placed preforms with engineered gas evacuation channels

Vacuum-bag-only (VBO) consolidation of automated fiber placed (AFP) thermoplastic composites can be a cost-effective processing route for large and complex thermoplastic composite structures. This paper explores the possibility of two-step AFP and VBO consolidation of advanced thermoplastic composites. Two commercially available carbon fiber reinforced Poly-Ether-Ketone-Ketone (C/PEKK) thermoplastic tapes were evaluated. Different process parameters were needed for the two material systems. Further, for the first time, an attempt was made to create in-plane air evacuation channels by deliberately introducing gaps between the tapes in the preforms during the placement. In the case of one material system, the VBO consolidation of preforms with and without gaps yielded good consolidation quality with less than 1% voids. In the other case, VBO consolidation of preforms with gaps showed a improved consolidation quality with less than 1% voids than the preform without gaps, indicating that the gaps possibly help accelerate the gas evacuation process.

Manufacturing of biodegradable Flax-PLA curvatures using a unique vacuum-temperature profile

In this research, the manufacturing of completely biodegradable composites with a unique single-step sheet consolidation method was discussed. Layers of unidirectional, coarse twill, and fine twill flax; and poly lactic acid (PLA) were used as the material system to manufacture cylindrical and spherical composite half-shells. The three processing parameters were vacuum pressure, temperature and time. Thickness, mass fraction, tensile strength, shear strength, shape conformance and biodegradability of the manufactured composites were experimentally determined. The composite specimens’ cross-sections were also observed under an optical microscope, to assess, the consolidation quality of the manufactured composites, that was represented by the composite thickness, and primarily governed by the polymer viscosity, and the transverse and in-plane fibre reinforcement permeability. Biodegradable Flax-PLA composites were successfully consolidated, within 5% tolerance of the targeted mass fractions and thickness values, conforming within 8% tolerance to the shape of the mould. The highest achieved shear strength, flexural modulus, tensile strength and elastic modulus, were 22 MPa, 19.9 GPa, 179 MPa and 19.5 GPa, respectively. This research will be valuable to develop, flat and curved biodegradable composites, for one-off or small scale productions, at a relatively low capital cost.

Review and analysis of secure energy efficient resource optimization approaches for virtual machine migration in cloud computing

Computing operations such as databases, networks, hardware, programs, analytics, and so on are all part of the cloud computing service. As such, it may serve as an option to in-house hardware and software. However, dynamic consolidation of VMs is required to improve power consumption, load balance, the frequency of migrations, Quality of Service (QoS), and the rate at which SLA violations are addressed, all of which contribute to better resource use. VM technology has quickly become a pillar of data centers and cluster systems because to its utility in partitioning, consolidating, and moving workloads. VM placement is another thing that affects the quality of consolidation. It is important to design a system that improves energy efficiency by allocating resources to applications in a smart way while still meeting QoS requirements for applications. Moreover, the security of information that is being processed during the migration process is also one of the important tasks. Hence, in this paper, review and analysis based on parameters and metrics for the VM migration under the influence of energy optimization, consolidation, and security have been investigated in a wider manner. Moreover, some open issues that are still prevalent in the current field have also been highlighted.

Development of Kevlar®/polypropylene towpregs through optimized commingling nozzle and processing parameters for thermoplastic composites

The current study aims at optimizing nozzle diameter and processing conditions for producing quality Kevlar®/polypropylene commingled towpregs meant for thermoplastic composite applications. ANSYS 3D CFD simulation and various experimental techniques are used for the same purpose. The study also investigates the effect of optimized commingled towpregs on the consolidation quality, void % and flexural properties of the developed UD composites. It is concluded that the nozzle diameter of 7 mm has proven to be ideal for producing quality towpregs as it leads to the formation of high nip frequency at 4.5 bar air pressure. The other nozzle diameters, 3 mm, 5 mm, and 9 mm, performed poorly in forming nips. Among these diameters, the 7 mm nozzle has optimum free space between the internal wall of the nozzle and the feed fibre bundle. This optimum space keeps the filaments within the potential air interaction zone and thus leading to the individual filament displacement and entrapment to form stable nips. The Box-Behnken design expert is used for obtaining ideal commingling conditions. The optimized Kevlar®/PP towpregs are produced using a custom fabricated commingling machine with a 7 mm diameter nozzle at the processing conditions - 4.5 bar air pressure, 2 m/min delivery speed, 3% and 1% overfeed, respectively for Kevlar® and polypropylene (PP). These commingled towpregs are flexible, compact, and regular in structure. These towpregs have the highest nip frequency, nip stability, weavability and homogeneous fibre-matrix mixing quality in yarn cross-section along the length. Using such towpregs makes the textile pre-forming effortless and yields composites with better resin impregnation quality and low void content. The UD Kevlar®/PP composites made through these towpregs offered good consolidation quality with a low void (4.3%). These composites showed flexural strength and modulus of 130 MPa and 28 GPa, respectively.

Sleep-dependent memory consolidation in breast cancer: Use of a virtual reality prospective memory task.

BackgroundPrevious studies have revealed both sleep alterations and prospective memory (PM) impairments in breast cancer (BC) patients. PM refers to memory of intended actions and is crucial for daily living tasks and treatment compliance. As sleep is known to favor memory consolidation, one may expect that changes in sleep quality related to BC would have an impact on PM performance. This study aimed at assessing sleep-dependent consolidation of intentions using an ecological, virtual reality-based PM task in BC patients not treated with chemotherapy.Materials and methodsThirty-seven early stages BC patients and 21 healthy controls (HC) participated in this study. PM was assessed using a virtual reality task, during which participants learnt a list of intentions and recalled them after a retention interval filled with a day awake or a night of sleep monitored by polysomnography. Sleep spindles and slow waves, brain oscillations involved in sleep-dependent memory consolidation, were quantified automatically using the Aseega software (Physip). Subjective sleep disturbances and markers of quality of life (psychological distress, fatigue, and well-being) were assessed by questionnaires.ResultsGreater PM performance was observed after sleep than after an equivalent period of daytime wakefulness for both groups (HC and BC). PM performance after sleep did not differ significantly between groups. Yet, BC patients reported greater sleep disturbances than HC which were related with poorer intentions retrieval, greater psychological distress, fatigue and poorer well-being. The frequency of spindles was higher and the amplitude of slow waves lower in BC patients compared to HC. However, no significant association was observed between polysomnography parameters and PM scores in the whole sample of participants.ConclusionAlthough subtle changes in brain oscillations involved in sleep-dependent memory consolidation were observed, these changes did not significantly impair overnight PM consolidation in BC patients. Nevertheless, poorer PM performance was associated with greater sleep complaints which in turn were related to poorer quality of life. Overall, these data suggest that sleep-dependent PM consolidation mechanisms are not altered in early stages BC patients not treated with chemotherapy. Further investigations are needed to understand the association between markers of quality of life and sleep-dependent memory consolidation.

The Spatiotemporal Changes in Ecological–Environmental Quality Caused by Farmland Consolidation Using Google Earth Engine: A Case Study from Liaoning Province in China

Farmland consolidation (FC) is among the measures to solve farmland issues, such as farmland fragmentation, and its impact on the ecological environment has always been controversial. In terms of long-term series and large-area analysis, the calculation of a large amount of data makes the analysis of the ecological–environmental quality of farmland consolidation very difficult. To solve this problem, our study applied a remote sensing ecological index model on the Google Earth Engine platform to analyze the changes in the ecological–environmental quality in two prefecture-level cities in Liaoning Province over the past 20 years. In addition, we analyzed the impacts of FC projects on the ecological environment from 2006 to 2018 and compared them to farmland without consolidation. The study results show that FC caused negative impacts on the quality of the ecological environment during the FC period (2006–2018) and that the FC’s positive effects take time to develop. In each FC phase, the results showed that FC exhibited negative effects before 2010 because the proportion of ecological–environmental quality reductions (0–47.67%) was higher than the proportion of increases (9.62–46.15%) in those FC phases. Since 2011, the area experiencing positive ecological–environmental benefits (31.96–72.01%) enabled by FC is higher than the area of negative impact (2.24–18.07%). This seems to be triggered by policy evolution. Based on the trend analysis, the proportion of FC areas with improved ecological–environmental quality grew faster (Gini index decreased 0.09) than that of farmland without consolidation (Gini index decreased 0.05) from before FC to after FC. Moreover, the new FC projects (2011–2018) performed better than the early projects (2006–2010), which may be due to policy evolution and technological advancements. However, the new FC projects (2011–2018) caused a dramatic decrease in ecological–environmental quality in a small number of areas due to the study time constraints. In conclusion, we believe that FC could improve the ecological–environmental quality of farmland, whereas some measures are needed to reduce its temporal negative impact on ecological–environmental quality, which may be caused by human interference. The remote sensing ecological index obtained using the Google Earth Engine platform provided an effective and reliable method for detecting the impacts of FC on the ecological–environmental quality of farmland. This could provide the basis and support for the monitoring of ecological–environmental changes in FC areas at a regional level.

Working state determination for concrete internal vibrator using genetic simulated annealing clustering method

The vibration duration is a key parameter for evaluating concrete consolidation quality. Based on the input current changing of internal vibrator drive motor when vibrator was inserted into concrete and pulled out concrete, this paper developed a device and proposed a method to determine the vibrator working state (insert or pull out). The current was collected through transformer and transmitted to single-chip microcomputer after rectified by current input module. The Chebyshev filtering method was adapted to filter the irregular fluctuation of the measured signal. The dual-threshold (idle current threshold and current difference threshold) method was proposed to determine the working state of vibrator. The current difference threshold was calculated using a genetic simulated annealing optimizing fuzzy C-means clustering method and it can distinguish normal current rise caused by inserting concrete and abnormal current rise caused by touching steel bar etc. when pulling out or moving vibrator. Considering vibrating concrete is a continuous process, the minimum vibrating time was flexibly set to correct the inserting state. Two misjudgment conditions were analyzed and proved that they had little effect on the overall accuracy. The identification accuracy and universality of the proposed method and device were verified by on-site application.

Accelerated low-temperature oxidation for sand consolidation and production control

Sand production that occurs in poorly consolidated oil and gas reservoirs causes many serious operational problems. Industry experts have used both chemical and mechanical sand control techniques to overcome this challenge; however, these techniques have various technical and economic limitations. For example, a technique that employed in-situ low-temperature oxidation (LTO) of an asphaltic solution saturating the near-wellbore area helped increase the formation's compressive strength while retaining its permeability; however, this technique was time-consuming at low reservoir temperatures. This study employed thermochemicals to preheat the sand and thereby accelerate the LTO reaction and shorten the consolidation process. First, small packs of loose sand saturated with an asphaltic solution were oxidized via external heating until consolidation. The optimal conditions involved continuous airflow for 6 h at 180 °C, which produced consolidated sand with a compressive strength exceeding 12.4 MPa. Second, a similar but insulated saturated sand pack was flooded with several pore volumes of thermochemicals, which raised its temperature from 75 °C to 188 °C; this was followed by 6 h of air injection. The consolidated sand had a compressive strength of 10.27 MPa and showed excellent stability against acid and crude oil floods as well as prolonged soaking in toluene.This study demonstrated the potential of using thermochemicals for the in situ heating of the wellbore area to elevated temperatures for sand consolidation. By shortening the treatment time, the thermochemicals improved the cost-effectiveness of sand consolidation via LTO without adversely affecting the consolidation quality.

Fast curing unidirectional carbon epoxy prepregs based on a semi-latent hardener: The influence of ambient aging on the prepregs Tg0, processing behavior and thus derived interlaminar performance of the composite

The aging behavior of a fast-curing epoxy resin (EP) was examined over three months in unidirectional carbon fiber prepregs for the first time. The semi-latent, 120 °C curing one-pot formulation was developed based on industry-grade diglycidyl ether of bisphenol A (DGEBA) resins without the necessity of B-staging, to fully monitor the property change by aging without any post-processing influence. To extend the shelf-life compared to standard wet EP systems, the latent dicyandiamide (DICY) and a semi-latent urea-based catalyst were used, leading to full conversion within 15 min. The conversion was monitored by increasing Tg0 and rheology. High quality unidirectional carbon prepregs were manufactured and then investigated over three months regarding tackiness and resin flow. In parallel, laminates were autoclave-manufactured to evaluate the aging influence on the interlaminar properties. Thus, a correlation between decreasing gel-time, interlaminar adhesion and resulting multiple crack growth was observed via GIC and interlaminar shear strength (ILSS) testing. The investigations show a clear influence of the consolidation quality of the prepregs based on ILSS values and GIC values. A decrease of 19% in ILSS and combined with an erroneous increase of 63% of the GIC due to multiple delamination was observed in the worst case.
