Microseismic velocity model inversion and source location: The use of neighborhood algorithm and master station method
Authors: Tan Yuyang , He Chuan , Mao Zhonghua
Published: March 2018

The accuracy of the velocity model strongly affects the accuracy of microseismic source location and hence the reliability of fracture imaging. We have developed a systematic methodology for microseismic velocity model inversion and source location. A new misfit function is used for both problems, which yields more reliable result than the conventional ones. Using the same measure of misfit, the location errors resulting from the use of different misfit functions are eliminated. The neighborhood algorithm and master station method (MSM) are adopted for calculating the velocity model and source location, respectively. The reason for using the neighborhood algorithm is that it has fewer tuning parameters and is easy to be tuned, whereas the advantage of the MSM is that it can automatically remove the mispicks. The performance of the proposed methods is illustrated using the ball-hit events with known locations, and the validity of the inversion results is verified by the relocations of these events. We also used the inverted velocity models to locate the microseismic events detected from the monitoring data. The location result indicates that the fractures have an average half-length of 280 m and height of 55 m and the fracture azimuth is approximately N77°W.

Purpose:

Reform of cancer care delivery seeks to control costs while improving quality. Texas Oncology collaborated with Aetna to conduct a payer-sponsored program that used evidence-based treatment pathways, a disease management call center, and an introduction to advance care planning to improve patient care and reduce total costs.

Methods:

From June 1, 2013, to May 31, 2016, 746 Medicare Advantage patients with nine common cancer diagnoses were enrolled. Patients electing for patient support services were telephoned by oncology nurses who assessed symptoms and quality of life and introduced advance care planning. Shared cost savings were determined by comparing the costs of drugs, hospitalization, and emergency room use for 509 eligible patients in the study group with a matched cohort of 900 Medicare Advantage patients treated by non–Texas Oncology providers. Physician adherence to treatment pathways and performance and quality metrics were evaluated.

Results:

During the 3 years of the study, the cumulative cost savings were $3,033,248, and savings continued to increase each year. Drug cost savings per patient per treatment month were $1,874 (95% CI, $1,373 to $2,376; P < .001) after adjusting for age, diagnosis, and study year. Solid tumors contributed most of the savings; hematologic cancers showed little savings. For years 1, 2, and 3, adherence to treatment pathways was 81%, 84%, and 90%, patient satisfaction with patient support services was 94%, 93%, and 94%, and hospice enrollment was 55%, 57%, and 64%, respectively.

Conclusion:

A practice-based program supported by a payer sponsor can reduce costs while maintaining high adherence to treatment pathways and patient satisfaction in older patients.
Sounds of Crossing
Authors: Chávez Alex E.
Published: March 2018

In Sounds of Crossing Alex E. Chávez explores the contemporary politics of Mexican migrant cultural expression manifest in the sounds and poetics of huapango arribeño, a musical genre originating from north-central Mexico. Following the resonance of huapango's improvisational performance within the lives of audiences, musicians, and himself—from New Year's festivities in the highlands of Guanajuato, Mexico, to backyard get-togethers along the back roads of central Texas—Chávez shows how Mexicans living on both sides of the border use expressive culture to construct meaningful communities amid the United States’ often vitriolic immigration politics. Through Chávez's writing, we gain an intimate look at the experience of migration and how huapango carries the voices of those in Mexico, those undertaking the dangerous trek across the border, and those living in the United States. Illuminating how huapango arribeño’s performance refigures the sociopolitical and economic terms of migration through aesthetic means, Chávez adds fresh and compelling insights into the ways transnational music-making is at the center of everyday Mexican migrant life.
Disrupting the three-dimensional regulatory topology of the Pitx1 locus results in overtly normal development

Published: March 2018

Developmental gene expression patterns are orchestrated by thousands of distant-acting transcriptional enhancers. However, identifying enhancers essential for the expression of their target genes has proven challenging. Maps of long-range regulatory interactions may provide the means to identify enhancers crucial for developmental gene expression. To investigate this hypothesis, we used circular chromosome conformation capture coupled with interaction maps in the mouse limb to characterize the regulatory topology of Pitx1, which is essential for hindlimb development. We identified a robust hindlimb-specific interaction between Pitx1 and a putative hindlimb-specific enhancer. To interrogate the role of this interaction in Pitx1 regulation, we used genome editing to delete this enhancer in mouse. Although deletion of the enhancer completely disrupts the interaction, Pitx1 expression in the hindlimb is only mildly affected, without any detectable compensatory interactions between the Pitx1 promoter and potentially redundant enhancers. Pitx1 enhancer null mice did not exhibit any of the characteristic morphological defects of the Pitx1−/− mutant. Our results suggest that robust, tissue-specific physical interactions at essential developmental genes have limited predictive value for identifying enhancer mutations with strong loss-of-function phenotypes.
Evolutionary divergence of the sex-determining gene MID uncoupled from the transition to anisogamy in volvocine algae
Authors: Geng Sa , Miyagi Ayano , Umen James G.
Published: March 2018

Volvocine algae constitute a unique comparative model for investigating the evolution of oogamy from isogamous mating types. The sex- or mating type-determining gene MID encodes a conserved RWP-RK transcription factor found in either the MT− or male mating locus of dioecious volvocine species. We previously found that MID from the isogamous species Chlamydomonas reinhardtii (CrMID) could not induce ectopic spermatogenesis when expressed heterologously in Volvox carteri females, suggesting coevolution of Mid function with gamete dimorphism. Here we found that ectopic expression of MID from the anisogamous species Pleodorina starrii (PsMID) could efficiently induce spermatogenesis when expressed in V. carteri females and, unexpectedly, that GpMID from the isogamous species Gonium pectorale was also able to induce V. carteri spermatogenesis. Neither VcMID nor GpMID could complement a C. reinhardtii mid mutant, at least partly owing to instability of heterologous Mid proteins. Our data show that Mid divergence was not a major contributor to the transition between isogamy and anisogamy/oogamy in volvocine algae, and instead implicate changes in cis-regulatory interactions and/or trans-acting factors of the Mid network in the evolution of sexual dimorphism.

Published: March 2018

To understand the pathology and molecular signatures of microangiopathy in diabetic neuropathy, we systemically and quantitatively examined the morphometry of microvascular and nerve pathologies of sural nerves. In the endoneurium of diabetic nerves, prominent microangiopathy evidenced by reduced capillary luminal area, increased capillary basement membrane thickness, and increased proportion of fibrin(+) blood vessels. Furthermore, capillary basement membrane thickness and the proportion of fibrin(+) blood vessels were correlated with small myelinated fiber density in diabetic nerves. In diabetic nerves, there was significant macrophage and T cell infiltration, and cluster of differentiation 40 (CD40) expression was increased. For molecular alterations in diabetic nerves, hypoxia-inducible factor-1α (HIF-1α), mitogen-activated protein kinase-activated protein kinase 2 (MK2), and phosphatase and tensin homolog (PTEN) were upregulated. In addition, HIF-1α was correlated with small myelinated fiber density and capillary luminal area, while both MK2 and PTEN were correlated with capillary basement membrane thickness in diabetic nerves. The molecular cascades were further demonstrated and replicated in a cell model of microangiopathy on human umbilical vein endothelial cells (HUVECs) exposed to high-glucose medium by silencing of CD40, PTEN and HIF-1α in HUVECs using shRNA. These data clarified the hierarchy of the molecular cascades, i.e., upregulation of CD40 leading to HIF-1α expression in endothelium and nerve fibers. In conclusion, this study demonstrated (1) the association of microangiopathy, thrombosis, and inflammatory infiltrates with nerve degeneration in diabetic nerves and (2) CD40 as a key molecule for the upregulation of HIF-1α and PTEN underlying the severity of microangiopathy.
Wash exhibits context-dependent phenotypes and, along with the WASH regulatory complex, regulates Drosophila oogenesis
Authors: Verboon Jeffrey M. , Decker Jacob R. , Nakamura Mitsutoshi , Parkhurst Susan M.
Published: March 2018

WASH, a Wiskott–Aldrich syndrome (WAS) family protein, has many cell and developmental roles related to its function as a branched actin nucleation factor. Similar to mammalian WASHC1, which is embryonic lethal, Drosophila Wash was found to be essential for oogenesis and larval development. Recently, however, Drosophila wash was reported to be homozygous viable. Here, we verify that the original wash null allele harbors an unrelated lethal background mutation; however, this unrelated lethal mutation does not contribute to any Wash oogenesis phenotypes. Significantly, we find that: (1) the homozygous wash null allele retains partial lethality, leading to non-Mendelian inheritance; (2) the allele's functions are subject to its specific genetic background; and (3) the homozygous stock rapidly accumulates modifications that allow it to become robust. Together, these results suggest that Wash plays an important role in oogenesis via the WASH regulatory complex. Finally, we show that another WAS family protein, SCAR/WAVE, plays a similar role in oogenesis and that it is upregulated as one of the modifications that allows the wash allele to survive in the homozygous state.
Classic and recent advances in understanding amnesia
Authors: Allen Richard J.
Published: March 2018

Neurological amnesia has been and remains the focus of intense study, motivated by the drive to understand typical and atypical memory function and the underlying brain basis that is involved. There is now a consensus that amnesia associated with hippocampal (and, in many cases, broader medial temporal lobe) damage results in deficits in episodic memory, delayed recall, and recollective experience. However, debate continues regarding the patterns of preservation and impairment across a range of abilities, including semantic memory and learning, delayed recognition, working memory, and imagination. This brief review highlights some of the influential and recent advances in these debates and what they may tell us about the amnesic condition and hippocampal function.
segment_liftover : a Python tool to convert segments between genome assemblies
Authors: Gao Bo , Huang Qingyao , Baudis Michael
Published: March 2018

The process of assembling a species’ reference genome may be performed in a number of iterations, with subsequent genome assemblies differing in the coordinates of mapped elements. The conversion of genome coordinates between different assemblies is required for many integrative and comparative studies. While currently a number of bioinformatics tools are available to accomplish this task, most of them are tailored towards the conversion of single genome coordinates. When converting the boundary positions of segments spanning larger genome regions, segments may be mapped into smaller sub-segments if the original segment’s continuity is disrupted in the target assembly. Such a conversion may lead to a relevant degree of data loss in some circumstances such as copy number variation (CNV) analysis, where the quantitative representation of a genomic region takes precedence over base-specific accuracy. segment_liftover aims at continuity-preserving remapping of genome segments between assemblies and provides features such as approximate locus conversion, automated batch processing and comprehensive logging to facilitate processing of datasets containing large numbers of structural genome variation data.
New Lower Bound and Exact Method for the Continuous Berth Allocation Problem
Authors: Xu Zhou , Lee Chung-Yee
Published: March 2018

We study a continuous berth allocation problem, where incoming vessels need to be assigned a mooring time as well as a berth location on a quay. It is a crucial element in port planning to achieve quick turnaround time for vessels. To solve this problem, many solution methods have been developed in the literature. However, gaps between the best-known lower and upper bounds on its optimal solutions are far from close. In this paper, we propose new and more effective solution methods for this important problem. By introducing a novel relaxation of the problem, we have derived a new lower bound that can be computed efficiently in quadratic time. By incorporating this new lower bound with some new heuristic and pruning techniques, we have developed a new exact method, based on a branch-and-bound approach. To demonstrate general applicability of the proposed methods, we have extended them to a more complicated problem, where decisions on berth allocations are restricted by a quay crane constraint. Extensive computational results have shown that, compared with previous state-of-the-art methods, our new methods have significantly reduced gaps between the lower and upper bounds and have solved more and larger instances to optimality in significantly less time. We have also performed sensitivity tests to demonstrate how robust the new solutions are against uncertainties in particular input parameters.

Reframing agency in abusive contexts: beyond ‘free choice’ and ‘open resistance’
Authors: Mirza Nughmana
Published: March 2018

South Asian women’s experiences of family abuse are not fully understood by state policy, particularly in relation to women’s ‘choices’ in response to abuse. Leaving an abusive relationship tends to be deemed the most, if not only, appropriate response. By drawing on the experiences of 11 Pakistani Muslim women, this paper argues that these simplistic assumptions overlook the diverse strategies women employ in response to abuse. These strategies range from compliance to overt forms of resistance, and they are complex and, at times, can be counterproductive and self-destructive. However, they challenge notions of passivity, and bring to light agentive behaviour best understood in the context of subordination and oppression that created the conditions of its enactment. What is important is that this paper should not create complacency in policy makers by reframing women as agents perfectly capable of altering the structures and constraints within which they are embedded. This paper proposes that government policy and service provider practice be shaped by an alternative perspective on women’s agency, one that recognises ‘exit’ as laden with difficulties and consequences for abused women, and one that does not insist upon physical acts of resistance to oppression as markers of agentive behaviour.
Cuckoos and recovery: an exploration of responsibility within UK domestic abuse awareness group programmes
Authors: Dix Laura
Published: March 2018

Major gaps exist in the literature around domestic abuse awareness courses and their aims and effectiveness (Williamson and Abrahams, 2014). This research explores the construction of responsibility within UK domestic abuse awareness programme discourse. Narratives of empowerment and responsibility for recovery for survivors can blur into others that blame the victim by making her responsible for ending future abuse (‘prospective responsibility’, Virkki, 2015) or try to ‘normalise’ or cure her from entering into another abusive relationship. This research demonstrates the need for further consideration around issues of agency, responsibility, temporality and empowerment within domestic abuse group discourse. It also raises concerns around the use of preventative education with women who have already experienced abuse: the underlying narrative of blame and responsibility for future safety is the ‘cuckoo’ in the nest that has the potential to push out the more positive message of recovery. Finally, it highlights the power of domestic abuse awareness discourse as a syllabus of recovery and empowerment and reinforces the need for further reflection on the role of groups within the UK.
Vulnerable bodily integrity: under-recognised sexual violence among girls in residential care institutions
Authors: Parkkila Helena , Heikkinen Mervi
Published: March 2018

Our focus is on under-recognised experiences of sexual violence among adolescent girls in residential care institutions in Finland. Sexual violations of the girls’ bodily integrity were connected to transactional sex and trauma-based behaviour. The girls’ experiences of sexual violence partly appeared to be internalised sexism, a form of collective social violence manifested on a personal level. However, if this phenomenon is discussed only as self-harming or self-abusive behaviour, it may be seen solely as an individual problem of the girls themselves, hiding the society’s and perpetrators’ responsibilities. Based on the feminist theoretical framework and critical evidence-based insights, we propose the term ‘internalised sexual violence’ to describe this phenomenon of under-recognised sexual violence. Recognising the inadequacy of the ‘victim–perpetrator’ view of violent experiences in one’s own life and naming the phenomenon of one’s own involvement are steps towards a proper and nuanced conceptualisation of internalised sexual violence. We recommend that this risk-taking and trouble-seeking form of sexual behaviour be recognised and identified in the World Health Organisation’s typology of violence. Moreover, there is a need to organise more training for both professionals and girls about gendered, sexualised violence and internalised sexual violence.
Evidence of Oxidative Phosphorylation in Zebrafish Photoreceptor Outer Segments at Different Larval Stages

Published: March 2018

Summary

Previous studies on purified bovine rod outer segments (OS) disks pointed to Oxidative Phosphorylation (OXPHOS) as being the most likely mechanism involved in ATP production, as yet not fully understood, to support the first phototransduction steps. Bovine and murine rod OS disks, devoid of mitochondria, would house respiratory chain complexes I to IV and ATP synthase, similar to mitochondria. Zebrafish ( Danio rerio) is a well-suited animal model to study vertebrate embryogenesis as well as the retina, morphologically and functionally similar to its human counterpart. The present article reports fluorescence and Transmission Electron Microscopy colocalization analyses of respiratory complexes I and IV and ATP synthase with zpr3, the rod OS marker, in adult and larval zebrafish retinas. MitoTracker Deep Red 633 staining and assays of complexes I and III–IV activity suggest that those proteins are active in OS. Results show that an extramitochondrial aerobic metabolism is active in the zebrafish OS at 4 and 10 days of larval development, as well as in adults, suggesting that it is probably maintained during embryogenesis. Data support the hypothesis of an extramitochondrial aerobic metabolism in the OS of zebrafish.

Real-world laboratories (RwLs) from an inside perspective: comparing interior design, sustainable development, transformation and learning in three RwLs, we present core issues for the future design of RwLs.Real-world laboratories (RwLs) as a new format within transdisciplinary
science aim at promoting learning for and transformation towards sustainability. However, what are essential aspects to take into account while initiating and stabilizing such processes within RwLs? Comparing lessons learned of three German RwLs (BaWü Labs), we show that for establishing
RwLs as melting pots for transdisciplinary research and societal transformation, four properties are crucial: an interior design that enables transdisciplinary research and intervention (in particular real-world experiments) based on a stable infrastructure; sustainability as guiding and operationalized
principle for differentiating the format “RwL” from other labs; overarching research programs for assessing transformative effects of RwLs and didactic concepts suitable for RwL circumstances. Since RwLs mainly address a long-term cultural change, a long-term funding and research
structure are essential as well.

Various experimental approaches of transformative research in real-world settings have emerged. Yet, similarities, differences, and specific contributions remain unclear. A characteristic-based comparison reveals complementarities and provides orientation.Real-world laboratories
(RwLs, German Reallabore) belong to a family of increasingly popular experimental and transdisciplinary research approaches at the science-society interface. As these approaches in general, and RwLs in particular, often lack clear definitions of key characteristics and their operationalization,
we make two contributions in this article. First, we identify five core characteristics of RwLs: contribution to transformation, experimental methods, transdisciplinary research mode, scalability and transferability of results, as well as scientific and societal learning and reflexivity. Second,
we compare RwLs to similar research approaches according to the five characteristics. In this way, we provide an orientation on experimental and transdisciplinary research for societal transformations, and reveal the contributions of this type of research in supporting societal change. Our
findings enable learning across the different approaches and highlight their complementarities, with a particular focus on RwLs.
What Is It Good For? Reflecting and Systematizing Accompanying Research to Research Programs
Authors: Defila Rico , Di Giulio Antonietta
Published: March 2018

Implementing innovative research formats such as real-world laboratories can be supported by accompanying research. On condition that their specifics are observed, accompanying research inquiring into the processes taking place and accompanying research facilitating the production of
integrated knowledge are particularly beneficial.There is hardly any tradition of accompanying research to running research programs and basically no scientific debate dealing with this kind of research. The paper contributes to this debate by suggesting a typology of accompanying research
based on the authors’ experiences in conducting such research. Given that its independence is preserved, accompanying research to research programs is not a luxury but provides added value. In cases where new or unusual formats of research are adopted, such as the format of transdisciplinary
and transformative real-world laboratories, it might even be a necessity. The paper is conceptual. It discusses the special nature (added value and success factors) of accompanying research to research programs along the dimensions “research” ‐ what kind of scientific knowledge
is produced?, “relationship to the actors” ‐ what is the special relationship to the other projects (and the funding agency)?, and “process-related tasks” ‐ what additional tasks can be incorporated? The accompanying research to the BaWü Lab
program will be presented against this backdrop.

J Strength Cond Res 32(7): 1892–1901, 2018—To investigate the within- and between-session reliability of the isometric midthigh pull (IMTP) in pre– and post–peak height velocity (PHV) female athletes. Nineteen pre- and 19 post-PHV athletes performed bilateral IMTPs using a custom-designed isometric testing system. Participants attended 3 separate testing sessions and performed 3 trials within each session. Peak force, relative peak force, force at 30, 50, 90, 100, 150, 200, and 250 ms, rate of force development (RFD) within time-specific bands, time to peak force (TPF), and time to peak RFD were obtained for analysis. Within- and between-session reliability for each variable was calculated from repeated-measures analysis of variance, intraclass correlation coefficients (ICCs), and coefficients of variation (CV) with 95% confidence intervals. Within- and between-session measures of absolute and relative peak force were found to be reliable for both pre-PHV (CV ≤ 9.4%, ICC ≥ 0.87) and post-PHV (CV ≤ 7.3%, ICC ≥ 0.92), but systematic bias was evident between sessions in the pre-PHV group, from session 1 to 2. Analyses of force at the specific time points revealed CVs between 19–37% and 5–24% for pre-PHV and post-PHV athletes, respectively. Greater variability was evident in TPF, and all RFD-related variables for pre-PHV (CV ≥ 38%) and post-PHV (CV ≥ 27%) athletes, respectively. The IMTP appears a reliable and safe method for evaluating peak force in young female athletes. Overall, post-PHV athletes were more reliable than pre-PHV athletes, with pre-PHV athletes needing additional familiarization to minimize the influence of systematic bias.
Asymmetries of cattle and crop productivity and efficiency during Brazil’s agricultural expansion from 1975 to 2006
Authors: Sparovek Gerd , Guidotti Vinicius , Pinto Luís Fernando Guedes , Berndes Göran , Barretto Alberto , Cerignoni Felipe
Published: March 2018

Brazil has global importance for food production and conservation of natural resources. The country has plans to increase yields and commitments to decrease deforestation that require higher productivity. Plans and policies for the growth of Brazilian agriculture, however, have been made without an integrated analysis of the harvest and not supported by a universal metric regarding its efficiency. Applying methods to model flows of energy and matter along food supply chains for agricultural production from 1975 to 2006, we found that crop and cattle harvests and their productivity have increased during the last four decades in consolidated and deforestation frontier regions. Yet in 2006, crop protein production was 20 times larger than cattle protein, using an area 2.6 times smaller than pastures. Crop protein productivity was 0.25 ton.ha–1 with emissions of 2 ton GHG per ton of protein, while cattle productivity was 0.01 ton.ha–1 with emissions of 283 ton GHG per ton of protein. From 1975 to 2006, the portion of crop protein and energy going to feed increased while the portion going to direct human consumption decreased. Our findings suggest that more efficient food systems would be achieved by a combination of intensification of cattle systems, optimization of feed-meat systems and an increase in the share of the consumption of crops as a source of protein. We suggest an initial road map to the expansion of the cultivated area and intensification of agriculture for zero deforestation, efficient and sustainable land use and food systems where cattle pasture intensification is a transition that will last until the expansion of crops replace all pasture present on suitable arable land. During this transition, pasture area will decrease until it is limited only to marginal non-arable lands. Such change could be achieved by a robust strategy that combines penalties and incentives and prevents the risks of a rebound effect for the intensification of agriculture.

Poseban je naglasak na motivima i likovima preuzetim iz prirode; priroda je izvor inspiracije, poprište čudesnih zbivanja i glavni lik. Oboje kroz likove biljaka, životinja, vjetrova, snijega i snjegovića, godišnjih doba i mjeseci, alegorijom i antropomorfizacijom, progovaraju o ljudima, ljudskim osobinama, patnjama i radostima, iznoseći vlastita životna iskustva, projicirajući ljudske odnose u društvu. Česti su formulaični početci i završetci, skloni su ponavljanju likova i motiva u više priča, oboje imaju notu didaktičnosti i sentimentalnosti, ali se ipak razlikuju poimanjem života i životnih ciklusa te osebujnim i prepoznatljivim stilom.

Članak se bavi problematikom vezanom za bitna svojstva ženidbe, jednost i nerazrješivost. Crkva je oduvijek promatrala ženidbu kao naravni bračni savez koji je među krštenima i sakrament, odnosno naravna stvarnost ženidbenog saveza uzdignuta je u nadnaravni red, u djelotvorni znak milosti. Bitna svojstva, jednost i nerazrješivost, koja su vlastita ženidbi kao naravnom savezu u kršćanskoj ženidbi zadobivaju posebnu čvrstoću. Ova svojstva bitna su i za kršćansku i nekršćansku ženidbu jer proizlaze iz same naravi i bitnih svrha ženidbe. Kršćanska tradicija i nauk svetoga Pavla naučavaju da su ova dva svojstva slika jedinstvene i nerazrješive veze Krista i Crkve. U članku je obrađeno i pitanje isključivanja bitnih svojstava iz ženidbene privole, odnosno dokazivanje ništavosti ženidbe zbog isključenja jednosti i nerazrješivosti pozitivnim činom volje.
Educational Series in Congenital Heart Disease Congenital left-sided heart obstruction

Published: March 2018

Congenital obstruction of the left ventricular outflow tract remains a significant problem and multilevel obstruction can often coexist. Obstruction can take several morphological forms and may involve the subvalvar, valvar or supravalvar portion of the aortic valve complex. Congenital valvar stenosis presenting in the neonatal period represents a spectrum of disorders ranging from the hypoplastic left heart syndrome to almost normal hearts. Treatment options vary dependent on the severity of the left ventricular outflow tract obstruction (LVOTO) and the variable degree of left ventricular hypoplasia as well as the associated lesions such as arch hypoplasia and coarctation.

Published: March 2018

A new approach is developed to study melting kinetics of n-Octadecane. Modelling of heat transfer during the melting of solid particle is described. The calculation results are in good agreement with experimental data on melting duration. The effect of applied electric field on melting kinetics is studied. Almost twofold increase of melting time is found in an electric field of strength E = 82 kv/m. In addition a rotation of a solid core inside a melt is observed, which is a manifestation of Quinke effect. A droplet shape evolution during phase transition is described. It is shown that initially elongated particle is almost spherical near the melting point and elongates again with the temperature rise. This shape evolution is explained by non-monotonous change of surface tension and is connected with rotational phase. Thus a possibility is shown to control a melting rate of normal alkanes using electric field.

The paper studied the elemental composition of lead alloys of appendage stamps and seals of Middle Ages, and the influence of impurity elements in the alloy and conditions for long-term storage of monuments on the course of corrosion processes and the formation of patina phase composition. Due to the influence of salts of orthophosphoric, hydrochloric and carbonate acids dissolved in the water environment on the artifacts surface patina coating is produced formed mainly of pyromorphite or pyromorphite and lead carbonate mixture. It was found that the corrosion rate of monuments depends essentially on the total content of Zn, Cd, Sn and Fe in lead alloy, which provide the protect for the main metal due to the electrochemical oxidation. Pink and brown colour of patina of certain attractions is associated with the pink colour of pyromorphite, which it takes as a result of isomorphic substitution of a small number of Pb atoms on Fe (III) ones. A colour of patine coating also depends on the content FeO, FeOOH and PbCO3∙Pb(OH)2.
