Gulag Heritage Conservation, Visualisation and Interpretation for Tourism Development: A Multi-Stakeholder Perspective

ABSTRACT In Kazakhstan, the development of a tourism sector that highlights the repressive historical period of Soviet domination is limited. This study investigates the managerial practices of the conservation, visualisation and interpretation of Gulag heritage for tourism development at Kazakhstani museums from a multi-stakeholder perspective. A qualitative case study research approach based on interviews with museum management, policymakers, NGOs, tour operators and historians of the Kazakhstani Gulags is adopted to examine stakeholders’ positions on practice. Various development and planning implications are identified: increase the cooperation between stakeholders for proactive cooperative fundraising for commercialisation and conservation of sites; and the need to consider the centrality of visual imagery in museum interpretation and initial multimedia development.
Dynamic Response Characteristics of the Structures under Excavation by High-Efficiency Blasting in the Urban Ultradeep Foundation Pit

To ensure the safe and efficient excavation of ultradeep foundation pits in a complex urban environment, the ultradeep foundation pit excavation project of Liuguangmen Urban Complex in Guiyang City was taken as the study point. A high-efficiency blasting method was proposed for the excavation of vibration-isolating slot and electronic detonators, and a three-dimensional spatial calculation model of the foundation pit structure was established. In addition, the field test and numerical simulation of the blasting vibration were developed. The feasibility of the high-efficiency blasting method was demonstrated, and the propagation law of the dynamic response characteristic parameters of the structure was explored using an electronic detonator and vibration-isolating slot. The results show that the electronic detonator carried out peak shaving within the group, unloading waves between the groups, and the blocking effect of the vibration-isolating slot, and all these effectively reduced the peak stress and peak particle vibration velocity, evenly distributed the vibration velocity, and guaranteed the safety of the surrounding existing buildings, proving the feasibility of the efficient blasting method. There is a “wall effect” at the supporting pile, whose propagation velocity is lower than that inside the rock mass, and the PPV is radial X > tangential Y > vertical Z. The peak values of stress, strain, and PPV all decrease with increasing supporting pile height, and there is an inflection point at 20 m. The internal nodes of the pile reciprocate without sharp change and failure in displacement. The peak displacement of different nodes is in the order X > Y > Z with increasing pile height, and the maximum peak value is 0.08 mm.
Economic Analysis of a New Business for Liposome Manufacturing Using a High-Pressure System

Supercritical assisted Liposome formation (SuperLip) is a lab-scale process for the production of liposomes. SuperLip was recognized as being a versatile supercritical assisted technique for the encapsulation of molecules for different industrial applications, such as pharmaceutic, cosmetic, textile, and nutraceutic purposes. The aim of this work was to perform an economic analysis to assess the profitability of the SuperLip process. The liposomes market was analyzed and the SuperLip process was compared to other techniques in terms of manufacturing advantages using the Canvas and Strengths, Weaknesses, Opportunities, and Treats (S.W.O.T.) models. SuperLip Plant Capital Expenditures (CAPEX) were estimated, and plant Operating Expenditures (OPEX) were also evaluated and integrated with personnel cost and other plant goods and services. A profit and loss statement was generated, together with a cash flow analysis. According to the market average selling price, liposome price is 1.8 €/mL; in order to join the market rapidly, the selling price of liposomes produced using SuperLip was set at 1.1 €/mL. A payback time has been identified at the fourth year of business. Economic indexes such as ROI and ROS were calculated on a 10-year business prospect, obtaining about a 230% return on investment and a 26.7% return on sales.
Optical properties of protein monolayers during assembly

Protein monolayers were built up by allowing protein molecules in solution to deposit at the solid/liquid interface. The structural evolution of these layers was followed using optical waveguide lightmode spectroscopy (OWLS). The measured effective refractive indices were interpreted using the uniform thin film model. For a relatively rigid, spheroidal protein (transferrin), the thickness of the layer was already established at very low surface coverages, and the refractive index increased during deposition. For a highly elongated and flexible protein (fibronectin), the converse occurred. The former case is consistent with classical random sequential adsorption. The latter result implies constant conformational rearrangement during deposition producing a compact proteinaceous membrane.
Influence of Structural Defects on the Resistivity and Current Flow Field in Conductive Thin Layers

The paper presents an analysis of the influence of microcracks in textronic conductive layers on their conductive properties. The tested structures were created in the physical vacuum deposition process. The paper presents the results of computer simulations of the current flow field in thin conductive stripes with defects distributed along a line perpendicular to the stripe axis and randomly placed on its entire surface. It was found, inter alia, that a larger number of shorter collinear defects may have many times lower resistance than a small number of longer defects of the same total length (e.g., with 40 collinear cracks with a total length of 90% of the strip width, the sheet resistance is only about 3% greater compared to a track without cracks). It was found that the percolation threshold of the tested models with square proportions and randomly selected defects is close to the value of 0.5. This is consistent with the theoretical calculations for analogous discrete models with infinite sizes. It was also found that the sheet resistance of the conductive strip with randomly distributed defects clearly depends on its length when the defect concentration exceeds 20%. The simulations were carried out on the basis of the integral equation method, with the solution presented in the form of double layer potentials.
Psychometric properties of the Persian version of the 27-item Elderly Attitude Questionnaire on End-of-Life Issues

Background & aims. Elderly people have different issues at the end of their lives. This study was conducted to analyze the psychometric properties of the Persian version of Attitudes of Older People to End of Life Issues (AEOLI) questionnaire. Methods. 189 elderly people participated in this descriptive study. Face, content and construct validity and reliability were assessed for determining the psychometric characteristics of the questionnaire. Construct validity was determined by exploratory factor analysis using principal component analysis with varimax rotation. Results. The results of this study indicate that the questionnaire has an appropriate face and content validity. Internal consistency (Cronbach’s alpha = 0.78, ICC = 0.729) showed a good reliability for the questionnaire. Factor analysis showed the nine items of the questionnaire can measure the attitude of the elderly toward end-of-life issues. Conclusions. The findings of this study showed that the Persian version of the 27-item questionnaire of the elderly attitude toward end-life issues has good validity and reliability.
On the non-homogeneous effect of financial transaction taxes

This paper investigates the impact of a financial transaction tax (FTT) in a classic financial market setting. The benchmark analysis is based on an extension of the model presented in Kyle (1985). Opposed to the existing literature, I am able to find equilibrium values with a linear tax. Results of the benchmark model confirm standard findings of FTTs, such as an increased bidâ€“ask spread and an overall less deep market. Importantly, I find that the introduction of a tax leads to a nonâ€“linear pricing function. In turn, the model predicts a decrease in market depth and trading aggressiveness for small trades, whereas for larger trades the introduction of an FTT only leads to increased prices and spreads.

Mucinous adenocarcinoma associated with anal fistula is a rare variant of adenocarcinoma, presents with delayed diagnosis, locally advanced, low nodal, and no distant metastasis. Adenocarcinoma associated with fistula (ACAF) is rare, has delayed diagnosis and poor prognosis but can be managed with neoadjuvant chemoradiation (NACRT) and complete curative resections with reconstruction by V-Y advancement cutaneous flap.
Healthcare Technology Management Professionals Are Influential for Device Safety and Reliability

Healthcare TechnologyManagement (HTM) professionals are key stakeholders in the medical device ecosystem. When HTMs report medical device concerns to Food and Drug Administration (FDA), they contribute to patient safety, as FDA ensures that medical devices remain safe and effective throughout their use across the continuum of patient care. The HTM's perspective provides valuable context and insights to medical device problems and can lead to device improvements. We present a device concern reported to FDA by HTMs and analyze the strengths of each report. The HTM's perspective, shared clearly and thoroughly, resulted in improvement to the device design to mitigate a recurrent malfunction.
Changing use of Lizard Island over the past 4000 years and implications for understanding Indigenous offshore island use on the Great Barrier Reef

Archaeological records documenting the timing and use of northern Great Barrier Reef offshore islands by Aboriginal and Torres Strait Islander peoples throughout the Holocene are limited when compared to the central and southern extents of the region. Excavations on Lizard Island, located 33 km from Cape Flattery on the mainland, provide high resolution evidence for periodic, yet sustained offshore island use over the past 4000 years, with focused exploitation of diverse marine resources and manufacture of quartz artefacts. An increase in island use occurs from around 2250 years ago, at a time when a hiatus or reduction in offshore island occupation has been documented for other Great Barrier Reef islands, but concurrent with demographic expansion across Torres Strait to the north. Archaeological evidence from Lizard Island provides a previously undocumented occupation pattern associated with Great Barrier Reef Late Holocene island use. We suggest this trajectory of Lizard Island occupation was underwritten by its place within the Coral Sea Cultural Interaction Sphere, which may highlight its significance both locally and regionally across this vast seascape.
Neonicotinoid Sunflower Seed Treatment, While Not Detected in Pollen and Nectar, Still Impacts Wild Bees and Crop Yield

Neonicotinoid seed treatments are commonly used in agricultural production even though their benefit to crop yield and their impact on pollinators, particularly wild bees, remains unclear. Using an on-farm matched pair design in which half of each field was sown with thiamethoxam treated seed and half without, we assessed honey bee and wild bee exposure to pesticides in sunflower fields by analyzing pesticide residues in field soil, sunflower pollen and nectar, pollen-foraging and nectar-foraging honey bees, and a sunflower specialist wild bee (Melissodes agilis). We also quantified the effects of thiamethoxam-treated seed on wild bee biodiversity and crop yield. M. agilis abundance was significantly lower with thiamethoxam treatment and overall wild bee abundance trending lower but was not significantly different. Furthermore, crop yield was significantly lower in plots with thiamethoxam treatment, even though thiamethoxam was only detected at low concentrations in one soil sample (and its primary metabolite, clothianidin, was never detected). Conversely, wild bee richness was significantly higher and diversity was marginally higher with thiamethoxam treatment. Nectar volumes harvested from the nectar-foraging honey bees were also significantly higher with thiamethoxam treatment. Several pesticides that were not used in the sunflower fields were detected in our samples, some of which are known to be deleterious to bee health, highlighting the importance of the landscape scale in the assessment of pesticide exposure for bees. Overall, our results suggest that thiamethoxam seed treatments may negatively impact wild bee pollination services in sunflower. Importantly, this study highlights the advantages of the inclusion of other metrics, such as biodiversity or behavior, in pesticide risk analysis, as pesticide residue analysis, as an independent metric, may erroneously miss the impacts of field realistic pesticide exposure on bees.
Complex Patterns of Antarctic Ice Sheet Mass Change Resolved by Time‐Dependent Rate Modeling of GRACE and GRACE Follow‐On Observations

The Antarctic Ice Sheet (AIS) is a major contributor to current global sea‐level change and the largest potential source of future sea‐level change. Variability in AIS mass balance on a wide range of spatiotemporal scales obscures secular trends, increasing the uncertainty of projections. We introduce a novel approach for analyzing satellite gravity observations to estimate time‐varying mass‐change rates and resolve the time scales and amplitudes of rate fluctuations. The new analysis resolves a higher degree of variability than expected over all AIS sectors. Quantifying rate fluctuations on a range of time scales, we demonstrate that loss from the West AIS is characterized by a multidecadal trend, whereas variations of the East AIS are dominated by substantial, short‐term accumulation changes that impact AIS mass balance as whole. These complex spatiotemporal variabilities highlight the need to include stochastic processes in estimates of loss rates.
Diverticular Disease of the Appendix Is Associated with Complicated Appendicitis

Introduction: Diverticular disease of the vermiform appendix (DDA) has an incidence of 0.004 to 2.1% in appendicectomy specimens. DDA is variably associated with perforation and malignancy. We report a single-center experience of DDA. The primary aim is to validate the association of DDA with complicated appendicitis or malignancy, and the secondary aim is to validate systemic inflammatory response syndrome (SIRS) criteria and quick Sepsis-related Organ Failure Assessment (qSOFA) scores. Methods: The histopathology reports of 2,305 appendicectomy specimens from January 2011 to December 2015 were reviewed. Acute appendicitis was found in 2,164 (93.9%) specimens. Histology of the remaining 141 (6.1%) patients revealed: normal appendix (n = 110), DDA (n = 22), endometriosis of appendix (n = 6), and an absent appendix (n = 3). Patient demographics, clinical profile, operative data, and perioperative outcomes of DDA patients are studied. Modified Alvarado score, Andersson score, SIRS criteria, and qSOFA scores were retrospectively calculated. Results: The incidence of DDA was 0.95%. Ten patients (45.5%) had diverticulitis. The mean age of DDA patients was 39.5 years (range 23–87), with male preponderance (n = 12, 54.5%). The median Modified Alvarado score was 8 (range 4–9), and the median Andersson score was 5 (range 2–8). Fourteen patients (63.6%) had SIRS, and none had a high qSOFA score. Eight patients (36.4%) had complicated appendicitis (perforation [n = 2] or abscess [n = 6]). Eleven (50%) patients underwent laparoscopic appendicectomy. There were three 30-day readmissions and no mortality. Conclusion: DDA is a distinct clinical pathology associated with complicated appendicitis.
FRACTAL MINKOWSKI-SHAPED RESONATOR FOR NONINVASIVE BIOMEDICAL MEASUREMENTS: BLOOD GLUCOSE TEST

This work presents a noninvasive measurement technique to detect the blood glucose level for diabetic individuals using a fractal microwave resonator printed on an FR-4 substrate. The proposed fractal is based on the 1st order of Minkowski open loops (MOL) coupled with an open-stub transmission line (OSTL) to increase the resonator selectivity at 2.45 GHz. Moreover, an air gap in the middle path of the OSTL is filled with multi wall carbon nanotubes patch (CNT) to increase the field fringing at a specific region. The proposed resonator is designed numerically with CST Microwave Studio. The size limitations for biomedical devices are considered to account for wearable applications. Later, an analytical study is presented on the proposed resonator sensitivity. The detection technique is based on the resonant frequency tuning, bandwidth variation, impedance matching change, and phase displacement for the S-parameters in the S11 and S12 spectra. The sample under test is mounted on a CNT patch of the OSTL which employs the characterization of the specimen. The proposed design idea could be generalized for a wide variety of biomedical detection liquids.
Why do small businesses seek support for managing people? Implications for theory and policy from an analysis of UK small business survey data

This article explores the characteristics of small and medium-sized enterprises (SMEs) that seek external human resource (HR) support and the circumstances in which they do so, drawing on the resource-based view (RBV) of the firm and recent growth theories. Original analysis of UK Longitudinal Small Business Survey data indicates that few SMEs seek HR support and that they are more likely to seek information than strategic advice. Resource deficiencies were not found to be a driver for seeking HR support, rather this was associated with business changes or challenges. Theoretically, we develop a model that identifies dynamic capabilities for HR support, integrated within an RBV framework. This is novel in integrating the concepts of ‘human process advantage’ and ‘human capital advantage’ from the strategic HR literature with dynamic capabilities theory. We draw out the implications of the findings and the model for future research and policy development.
Molecular weights and molecular weight distributions of liquefied wood obtained by acid‐catalyzed phenolysis

By means of gel permeation chromatography analysis, the molecular weights and molecular weight distributions of liquefied wood obtained under various liquefaction conditions and species of catalysts were investigated in order to trace the change in the structural characteristics of the liquefied wood. The results indicated that during the liquefaction reaction, wood components were subjected to decomposition, phenolation, and recondensation. The intensities of these reactions depended greatly on the reaction conditions and the species of catalysts, and their competing result determined the structural characteristics of the resulting liquefied wood. © 1997 John Wiley & Sons, Inc.

DBU Catalyzed Phospho-Aldol-Brook Rearrangement for Rapid Preparation of α-Phosphates Amide in Solvent-Free Conditions

The 1,8-diazabicyclo [5.4. 0] undec-7-ene DBU-catalyzed Phospho-Aldol-Brook Rearrangement reaction of α-ketoamide and dialkyl phosphites was developed under solvent-free at room temperature. The novel α-Phosphate Amide derivatives could be obtained with good yield (86–96%), which also exhibited good tolerance of various dialkyl phosphites and α-ketoamide, including isatins. In addition, the reaction was conducted in both gram-scale and mol-scale, and the title compounds could also be obtained in excellent yield (more than 91%) within 5 min.
Inactivation of Enzymatic Browning Reaction Affects Sorption Isotherms of Chilli

The adsorption and desorption isotherms of chilli (Capsicum annuum cv. Huarau Yon) were obtained using the gravimetric method. Blanching was used in order to inactivate enzymatic browning reaction and to determine the equilibrium moisture content of blanched chilli compared with fresh chilli. The experimental data were fitted with the selected models using nonlinear regression. The mean relative deviation, the coefficient of determination, and standard error of estimation were used as the criteria for the validity of each model. Five-parameter and six-parameter GAB models were found to fit sorption isotherms of fresh and blanched chilli, and the modified Oswin model was selected to represent adsorption isotherms of dried chilli. The isothermal data were also used to calculate the energy required for evaporation by means of Othmer plots. The heat of desorption between fresh and blanched chilli was not different at moisture contents of over 10%.
