As a continuation of studies of carbacylamidophosphate based coordination compounds a series of the lanthanide and yttrium complexes of general formula PPh4[LnL4], where Ln=La, Nd, Tb and Y; L– = [CCl3(CO)N(PO)(OCH3)2]– has been synthesized. The resulting compounds were characterized by means of thermal gravimetric analysis, IR, 1H NMR, UV-Vis absorption and luminescent spectroscopy. It was found, that each lanthanide ion of the [Ln(L)4]– complex anion is bonded to two oxygen atoms belonging to the phosphoryl and carboxyl groups of four bidentate chelated ligands, completing coordination number of lanthanide ion to eight. Analysis of signals integral intensity in the investigated NMR spectra of coordination compounds PPh4[LnL4] (Ln = La, Y) indicates the molar ratio of dimethyl-N-trichloroacetylamidophosphate ligand and tetraphenylphosphonium cation as 4:1, which corresponds to the proposed structure of the complexes. According to the absorption spectroscopy investigations data there is one type of lanthanide sites in the complexes. Low symmetry of lanthanide ion coordination environment was concluded from bands ratio in the europium complex luminescence spectrum. From the TGA analysis the stability of the coordination compounds till 160°C can be concluded. It was shown that tetraphenylphosphonium cation sensitizes europium ion emission and photo-excitation of PPh4[EuL4] complex by UV light results in red Eu3+ centered luminescence with dominating band of 5D0–7F2 transition in the spectrum and decay time equal one and a half millisecond.

Published: April 2019

Rheumatological illnesses are common differential diagnosis in the evaluation of childhood fever of unknown origin (FUO). We report an 11-year-old female child referred as FUO for eight months, possibly sarcoidosis. Her past records showed treatment for UTI, enteric fever in initial two months of fever. She was referred to tertiary institute due to recurrence of fever, multiple joint pain, right eye pain where she underwent evaluation for FUO. Investigation showed positive anti-nuclear antibody (ANA), elevated ESR. She was diagnosed as a case of juvenile idiopathic arthritis (JIA) with uveitis and treated with steroids, disease-modifying anti-rheumatic drugs (DMARDs). Two months later, she developed fever, multiple joint pain and worsening right eye visual acuity. Ophthalmic reevaluation revealed panuveitis and periphlebitis. CT chest showed mediastinal lymphadenopathy. With the above features, childhood sarcoidosis was suspected and treated with T. Azathioprine. Child was referred to our institute due to return of fever spikes. On examination, she had intermittent fever, plaque like lesion in cheeks? Lupus pernio, but skin biopsy was suggestive of SLE. Investigations showed positive ANA by indirect immunofluorescence (IIF), positive anti dsDNA (IIF), low complement (C3), positive immunoblot for SmD1, U1RNP, SSA/Ro60. Diagnosis was revised as childhood SLE with one clinical and three immunological criteria. She responded to steroids and immunosuppression. We report this case of childhood lupus presenting as FUO, multiple joint pain, uveitis, periphlebitis, without specific skin lesions, renal and hematological manifestations. We emphasize the need for meticulous evaluation and long term follow up for children with FUO diagnosed as rheumatological illness. The slow evolution of disease process and atypical presentation of common illnesses may lead to diagnostic dilemma.

Authors: Fomin A.E. , Bogomolova E.A.
Published: April 2019

In article the problem of metacognitive monitoring of the solution of educational tasks is condemned. The role of heuristic processes as source of possible distortions in metacognitive judgments is shown. Results of pilot study in which influence of reasonings of pupils on own knowledge on characteristics of monitoring (N = 58 is studied are presented; middle age — 19,5 years; 5 young men, 53 girls). It is revealed: 1) the students formulating the arguments disproving their knowledge were less sure of the solution of test tasks, than the students who were putting forward arguments in support of correctness of the knowledge (p = 0,016); 2) students from group which put forward the disproving arguments showed more positive changes of accuracy of monitoring, in comparison with students from group which put forward the arguments confirming their knowledge (p = 0,032); 3) the procedure of reasonings on own knowledge did not reduce influence of heuristic processes on creation of judgments of metacognitive monitoring; 4) students with lower level of subject knowledge showed big changes in indicators of metacognitive monitoring in comparison with the students having more high standard of knowledge (р = 0,043). The prospects of use of the procedure of reasonings on knowledge as development tools of skills of monitoring are discussed. Some restrictions of results and conclusions of a research are specified.

Published: April 2019

Designing a model of autonomy development for adolescents is an important aspect of the research. The article describes the process of Designing and validating the «Adolescents’ Readiness for Independent Living» questionnaire. The «Adolescents’ Readiness for Independent Living» questionnaire is an adaptation of the Ansell-Casey Life Skills Assessment (ACLSA) Youth 4 — Version 4.0 [32].A distinctive feature of the modified questionnaire is the use of a series of focus groups with adolescents attending residential institutions and the formulation of questions that allow us to measure the independence of adolescents in Russia. The questionnaire is based on the concept of hardiness, according to which life skills promote the socialization of adolescents into the world of «adulthood» and uncertainty. An empirical study assessed adolescents’ readiness for independent living; it was conducted in Moscow and the Yamalo-Nenets Autonomous Okrug, with a total sample size of (N = 179) respondents, 76 of them boys, 103 girls, and with an average age of 17 years. Two-factor analysis of variance was used for further analysis. Gender and place of residence (with the family or at boarding school) were taken as independent dichotomous variables. The scores for each scale were the dependent variables. The reliability of the questionnaire was demonstrated, as well as its construct validity and convergent validity. Recommendations are made for researchers working or planning to work with adolescent samples.

Published: April 2019

Dentinogenesis Imperfecta type II (DI2), also known as hereditary opalescent dentin, is one of the most common genetic disorders affecting the structure of dentin, not related with osteogenesis imperfecta, which involves both primary and permanent dentitions. The purpose of this article is to perform a scoping review of the published peer-reviewed literature (1986–2017) on DI2 management in children and to outline the most relevant clinical findings extracted from this review. Forty four articles were included in the present scoping review. According to the extracted data, the following are the most important tasks to be performed in clinical pediatric dentistry: to re-establish the oral mastication, esthetics, and speech, and the development of vertical growth of alveolar bone and facial muscles; to reduce the tendency to develop caries, periapical lesions and pain; to preserve vitality, form, and size of the dentition; to avoid interfering with the eruption process of permanent teeth; to decrease the risk of tooth fractures and occlusion disturbances; to return the facial profile to a more normal appearance; and to prevent or treat possible temporomandibular joint problems. Therefore, Pediatric Dentists should bear in mind that early diagnosis and treatment, together a long-term follow-up of DI2 in children, continue to be the best approaches for achieving enhanced patient psychological well-being and, in consequence, their quality of life.

INTRODUCTION TO SPECIAL ISSUE: UNDERSTANDING AND RESPONDING TO PAIN-BASED BEHAVIOUR IN CHILD AND YOUTH CARE WORK
Authors: Anglin James P. , Zaharieva Lilia M.
Published: April 2019

We are grateful to Dr. Sibylle Artz, Editor of the International Journal of Child, Youth and Family Studies, for the invitation to produce a special issue on pain-based behaviour in child and youth care work. Since the term was created and published in 2002 (Anglin, 2002), the notion has entered the literature, the research, and, perhaps most importantly, the practice of child and youth care internationally. The eight articles in this issue come from Ireland, Australia, the United States, and Canada, and offer a broad range of perspectives.After receiving the invitation to compile this issue, we scanned the recent child and youth care literature and readily identified 13 publications — articles and books — using the term pain-based behaviour. There are undoubtedly many more, however we believed the authors of these publications would present a significant cross-section of perspectives on understanding and responding to pain and pain-based behaviour. We are excited and honoured that the authors represented here were able to contribute articles to this issue.

Published: April 2019

Recognition of the molecular mechanisms of keratinocyte participation in normal skin homeostasis and in pathogenesis may lead to creation of more effective tools for topical application of cosmetics, cosmeceutics and drugs to a particular location within the skin for prevention and therapy of many skin disorders and diseases. For this purpose, the PAMAM G3 dendrimer with amide linkages of 9 biotin molecules and 10 molecules of pyridoxal phosphate (BC-PAMAM) was constructed, and its biological properties and cellular uptake and localization were investigated in the HaCaT keratinocytes. BC-PAMAM is nontoxic for HaCaT cells, as estimated by two assays (Neutral Red and tetrazolium salt reduction, XTT), and revealed low apoptosis induction at up to 50 µM concentration. Fluorescent labeled BC-PAMAM accumulates in HaCaT cells with high efficiency in a concentration–dependent manner. Its mitochondrial localization, estimated as Mander’s colocalization coefficient, is substantially lower than the native PAMAM, and that correlates with its cytotoxicity. The only undesirable, but significant inhibitory effect on cell mobility, evaluated by the wound healing test, was observed at 10 µM BC-PAMAM. The important anti-inflammatory action of BC-PAMAM was clearly documented by decreased production of total IL-1α, assayed with an ELISA test with unstimulated and stimulated by bacterial antigens (LPS and GroEL) HaCaT cells. Thus, it is expected that the biotin pyridoxal phosphate conjugated PAMAM may be considered as a potential carrier for safe delivery of vitamins and drugs into the epidermis.

Authors: Berdalinova A. K. , Umbetov T. Zh. , Shevlyuk N. N. , Zhurabekova G. A.
Published: April 2019

The aim of the study was to clarify the morphological and functional changes in the liver under the effect of sodium tetraborate.

Material and methods. Morphological and functional characteristics of the liver of white outbred rats under single and long-term exposure to sodium tetraborate were studied using histological, histochemical, immunocytochemical and morphometric methods. Experimental animals were divided into 2 groups. Animals of the first group once intragastrically administered sodium tetraborate at a dose of LD50, animals of the second group daily for a month administered sodium tetraborate at a dose of 1/10 LD50. Animals of the first group were removed from the experiment a day after the introduction of sodium tetraborate, animals of the second group – 7, 14, 21 and 30 days after the start of the experiment.

Results. Both single and long-term exposure to sodium tetraborate in the liver lobules marked multiple focal death of hepatocytes, microcirculation, bile stagnation in the biliary tract. The degree of damage and death of hepatocytes increases from the periphery to the center of the lobule. With prolonged exposure to sodium tetraborate in the first half of the experiment, stagnation of the blood elements in the capillaries was rare, and with an increase in the duration of the experiment (from 7 to 30 days), the proportion of intra-lobular sinusoid capillaries with stagnation of the shaped elements in them increased and more than half of the capillaries showed stagnation of the blood elements in them. Destructive changes in the liver were more pronounced when exposed to sodium tetraborate at a dose of LD50.

Conclusion. In the conditions of low concentrations of sodium tetraborate in the liver, both destructive processes and transformations aimed at compensating for damage occur. With an increase in the dose of sodium tetraborate, the adaptive capabilities of the organ are exhausted and do not compensate for the damage to the cell structures of the organ.

Published: April 2019

The aimis to study the structure of the femur of conditionally healthy modern people, as part of the link of the musculoskeletal system, providing bipedal locomotion.

Material and methods.By the original osteometric method was measured 23 structures of 166 femoral  bones with full synostosis of epiphysis without evidence of bone pathology. After the introduction of the coefficient of proportionality for linear parameters and the calculation of confidence intervals for each of them, a multilevel factor analysis was carried out, separately for the right and left femoral bones by the maximum likelihood factor analysis method with Equamax normalized rotation.

Results.Four levels of the structural organization, which characterized by asymmetry of factor loadings, are identified. The parameters forming the 1st level ensure the transfer of the mechanical load along the limb axis from the head through the intertrochantcric crest to the medial condyle. 2nd level parameters provide rotational movements at the knee joint. Parameters of the 3rd and 4th levels reflecting the function of the rotation of the leg in the hip joint when upright and maintaining the vertical position of the body in the sagittal plane.

Conclusion.Thus, the human femur is a multilevel system with asymmetric participation of parameters in its formation. Femur, as part of the musculoskeletal system, has a distinct vertical structural differentiation, which is manifested in the dominance of the right limb in the implementation of the support functions at the level of the proximal epiphysis, and motor functions at the level of the distal epiphysis of the femur.
Adição de cinzas do bagaço da cana-de-açúcar em compósitos cimentícios reforçados com fibras de sisal
Authors: Secchi Maicon , Neves Junior Alex
Published: April 2019

O cimento Portland é o segundo material mais utilizado pelo ser humano, sua fabricação demanda elevado consumo de energia e gera grandes quantidades de gás carbônico. O Brasil tem hoje um fator de emissão de aproximadamente 610 kg CO2/ton cimento produzido, gerando mais de 10 milhões de toneladas de CO2 somente no ano de 2017. Como forma de diminuir o consumo energético e diminuir a emissão do gás carbônico na atmosfera, tem-se como alternativa a incorporação de materiais pozolânicos ao cimento, que geram benefícios tanto tecnológicos, mas também econômicos e ecológicos. Assim, objetivou-se nesse trabalho avaliar, tanto por termogravimetria quanto mecanicamente, a influência da incorporação de cinza do bagaço da cana-de-açúcar (CBC) como material pozolânico em compósitos a base de cimento Portland, reforçados com fibras curtas de sisal. Produziram-se pastas com substituição de cimento por CBC nos teores de 5, 10 e 15%, sendo que estas pastas foram produzidas atingindo o Índice de Consistência Normal determinando o fator água/material cimentante ideal para o nível de consistência requerido. As pastas foram ensaiadas por meio de Termogravimetria e Termogravimetria Derivativa (TG/DTG), bem como avaliada a sua resistência à compressão. Foram produzidas placas de compósitos de matriz cimentícia reforçados com fibras de sisal, com e sem a presença de CBC, as quais foram rompidas à tração na flexão aos 28 dias de idade. Os resultados indicaram que a pasta com teor de 5% de CBC não apresentou diferença significativa de resistência à compressão em relação à referência, porém diminuiu em 30% a quantidade de hidróxido de cálcio aos 28 dias. Os compósitos apresentaram comportamento denominado strain-softening e o mesmo teor de substituição de 5% manteve a carga de primeira fissura e máxima resistência à tração, quando comparado à referência.

É crescente a preocupação com a economia de energia e com a preservação do meio ambiente nos últimos anos. Como consequência, o tema relacionado a desempenho de edificações tem sido amplamente abordado, incluindo a busca por novos materiais e sistemas construtivos que proporcionem melhor habitabilidade e conforto térmico. Nesse sentido, este trabalho tem por objetivo avaliar o impacto da substituição parcial de pó de pedra por argamassa industrializada termoisolante nas propriedades física e mecânica de blocos de concreto de vedação vertical. A metodologia consistiu da realização de ensaios de caracterização dos materiais constituintes, condutividade térmica e resistência mecânica dos blocos confeccionados com a argamassa termoisolante. Inicialmente, foram moldados blocos da família M20 com dimensões 19x19x39cm, a partir do traço de 1:18 (relação cimento: agregados) tradicionalmente utilizado na indústria local. Posteriormente, estes foram confeccionados com substituição no volume do pó de pedra, nos teores de 6%, 12% e 24% de argamassa isolante em relação à massa de pó de pedra. Os resultados evidenciaram que a adição da argamassa isolante no traço dos blocos de concreto, promoveu melhoria no desempenho térmico e influenciou negativamente a resistência mecânica, ocasionando progressiva redução à medida que se elevada a porcentagem de argamassa isolante. Por meio de correlações, foi possível definir que o teor de incorporação de 2% proporciona resistência mecânica adequada e acima do limite normativo, bem como redução média de 9,3% e 40% na condutividade térmica, em relação ao traço de referência e ao valor teórico proposto na norma vigente, respectivamente. Destaca-se, portanto, a importância de caracterizar termicamente os componentes dos sistemas de vedação vertical, considerando os materiais utilizados na região, o que possibilita trabalhar com valores mais realísticos de suas propriedades térmicas.

It is known that tensile strength of soil samples is by three orders of magnitude greater than the shear stresses on the bottom of slope streams responsible for the detachment and transport of soil particles by water current. C.E. Mirtskhulava believed that detachment of soil particles by water current occurs due to the fatigue destruction of bonds between soil particles.Taking this fact into account, tensile strength is lower by two orders of magnitude. M.A. Nearing had an opinion that detachment of soil particles occurs in the points of separation of vortices from the bottom of the stream, where the shear stress is by two orders of magnitude higher than the average. These approaches did not explain overcoming by slope streams of the cohesion forces between soil particles. Studies of the influence of water temperature on the washout rate of model samples have shown that the soil erosion is highly dependent on the water temperature, which is close to the Van’t Hoff’s rule. This means that destruction of bonds between soil particles is probably the result of interaction between the soil solid phase and water molecules. Experiments have also shown that destruction of bonds between soil particles in the sample of chernozem monoaggregate soil occurs under a layer of still water. Upon the start of the water flow, particles that lost bond with the rest of the soil body immediately break away. The number of particles with disrupted bonds grows with the duration of the sample exposure to still water, although with some flattening. Experiments confirm the validity of the hypothesis of non-hydraulic nature of forces that disrupt inter-aggregate bonds during water erosion.

Published: April 2019

Pillar replacement in mining works is a technique of using the pillars that are part of the support structures having a high degree of mineralization, which attracts economic interest. The technique consists of replacing the support pillars of the mineral matrix that contain appreciable and beneficial quantities of mineral by artificial pillars that provide geomechanical structure to the operations, generating support and safety benefits greater than or equal to those provided by the original pillars and thus maximizing the intrinsic economic value of the available rock in the operation. Based on the literature regarding design techniques for the assembly of pillars used in underground gold mining, daily and continuous field inspections were conducted for two months, taking the necessary data for the proposed design following ISRM standards for data collection. The proposed pillars must consider a set of operational economic requirements and meet the geomechanical performance required to guarantee the safety and stability of the site. The design consisted of a combination of two types of pillars, one of concrete and one of mesh, cables and sterile material (granodiorite and dyke). The measurements consisted of RMR determination, the dimensions of the current pillars, and the geomechanical condition using detailed scanlines. Subsequently, the information was refined and correlated, and the degree of fracture and safety factor of the original pillars versus those proposed in the new designs were calculated. As a result, the optimal design for the construction of the replacement pillars should have dimensions of 2 x 1.7 x 1.7 meters, achieving a safety factor of 1.36, complying with the geomechanical requirements of safety and stability and yielding a profit of 405 % as a cost-benefit ratio in replacing the original pillars by those proposed in the design; the sterile material and mesh pillars would have dimensions of 2 x 2 x 2 meters.
Resource–Economic Growth Nexus, Role of Governance, Financial Development, Globalisation and War: Dynamic Approach
Authors: Niknamian Sorush
Published: April 2019

This study reassesses the resource–economic growth nexus by incorporating several channels. Advanced panel time series techniques are used to analyse panel time series data from 1980 to 2015 in 31 oil-rich countries. Results show that oil rent augments economic growth; thus, oil rent is conducive rather than impediment for economic growth. The role of governance in economic growth is significant in the selected countries. Oil rent exerts a positive significant impact on economic growth in countries with good governance compare to countries with poor governance. Financial development is an unimportant channel in the resource–growth nexus because FD is often unable to mobilise oil rent from the government to the private sector in oil-rich countries. Globalisation is advantageous for countries and promote economic growth. Moreover, war exerts a significant negative effect on growth in the long term.
Organizational Justice, Job Stress, and Work-family Conflict: Their Interrelationships in Universities' Personnel
Authors: Niknamian Sorush
Published: April 2019

Presence of justice in an organization plays a crucial role on employees' well-being and remarkable success of the organization itself. This fair environment may be an important factor in lower levels of stress, which is associated with balancing demands between work and family domains among employees at university. The main purpose of this study is to investigate the relationship between distributive, procedural, and interactional dimensions of organizational justice and job stress, between work-family conflict and job stress, and whether the perception of organizational  justice elements do influence work-family conflict. In sum, drawing upon 146 non-academic employees at 5 state universities in Iran, our result indicated that interactional justice had the strongest negative relationship with stress at work and work-family conflict. Moreover, the reciprocal correlation was found between job stress and work-family conflict. Hence, in order to decrease level of stress and to better manage the work and family lives, organizations need to promote justice in workplace.

Se ha analizado para toda Europa la red espacial de conexiones societarias internacionales filtradas en los denominados papeles de Panamá. Esto ha permitido conocer la morfología espacial de la estructura financiera de evasión de capital desde Europa a paraísos fiscales de todo el mundo. También permite elaborar una cartografía de flujos de capital financiero en Europa que identifica sus puntos de origen, tránsito y destino. El resultado revela la existencia de diferentes espacios financieros en el interior del continente, así como territorios fuera de Europa que se encuentran bajo el control geopolítico de la UE, y que constituyen nodos críticos como destino final del capital. El más importante con diferencia pertenece a los restos del imperio colonial inglés. Se trata  de un espacio utilizado por Reino Unido para establecer una red financiera mundial que tiene su epicentro en la City y su destino final en las Islas Vírgenes Británicas.
Wernicke’s encephalopathy in a patient with severe acute pancreatitis after cholecystectomy and exploration of biliary tract
Authors: Du Huihui , Lei Xiaohua , Liu Qiang , Xu Xundi
Published: April 2019

Background

Wernicke’s encephalopathy (WE) is a disease classically associated with thiamine deficiency,and generally presents with the triad of opthalmopathy, ataxia and altered mentality. However, and delayed diagnosis and treatment may lead to severe irreversible neurological damage, or even death. Only about 20% of the cases can be defined from the relevant literature, with the rest unnoticed and thus unreported. Here, we would like to report a case of a patient with severe acute pancreatitis who suffered from Wernicke’s encephalopathy after cholecystectomy and exploratory of biliary tract.

Case presentation

A 37-year-old Chinese male patient diagnosed with severe acute pancreatitis was admitted to our institute’s hospital for further treatment. The patient had a 50-days history of abdominal pain as well as 8-days emesis, and wasn’t addicted in alcohol consumption. He did not receive any regular physical examination or treatment. One months before cholecystectomy and exploratory of biliary tract,he was noted to have abdominal pain, poor appetite, emesis and sclera icterus .He was referred to the local hospital, received supportive treatment, including antibiotics and liver-protection drugs . However, he got worse after those treatment,so transferred from the local hospital to our hospital for further therapy.. After operationhe was admitted in general ward for further treatment. When his vital signs and laboratory examination came to stability. He recovered well with supportive treatments, including antibiotics, liver-protection, protecting gastric mucosa and so on. However,his oral intake was low, and he was solely dependent on total parenteral nutrition without vitamin B1. On the 7th post-operative day, psychiatric and neurological disorders appeared without an obvious cause, symptoms including babbling, irritability, apathy, non-purposeful movements, and dystaxia. On the basic of his clinical manifestations and brain magnetic resonance imaging scan results, Wernicke encephalopathy was eventully diagnosed.

Conclusions

Although extremely rare, this index patient highlights that Wernicke’s encephalopathy could be associated with severe acute pancreatitis. This is very helpful for the therapeutic implications and evaluating curative effect. A multivitamin and thiamine should be provided for patients who have a surgery of cholecystectomy and exploratory of biliary tract so as to prevent and cure Wernicke’s encephalopathy.

Does Fetal Fibronectin Predict the Delivery Route in Nulliparous Women at Postterm Induced by Dinoprostone?
Authors: Goksever Celik Hale , Celik Engin , Yetkin Yildirim Gonca
Published: April 2019

Objective: Digital cervical evaluation has been used to determine the likelihood of vaginal delivery which is considered by many women to be non-tolerable. Recently, alternative approaches such as transperineal ultrasound, fetal fibronectin test in cervicovaginal secretions have been investigating for the prediction of the delivery route. We aimed to study whether the usefulness of qualitative fetal fibronectin test in cervicovaginal secretions for the prediction of vaginal delivery in pregnant women at postterm induced with dinoprostone.Study design: A total of 32 nulliparous pregnant women at postterm were enrolled in this prospective observational study. Fetal fibronectin test was applied to all participated women before the induction with dinoprostone and transvaginal ultrasonography was performed to measure cervical length.Results: The women having positive fetal fibronectin test result gave birth through vaginal route, except one case. Although there is no statistically significant difference, the shorter cervical length was associated with vaginal delivery in our population.Conclusion: Fetal fibronectin test has a predictive value for delivery route in nulliparous women at postterm. Fetal fibronectin test may be used as a “rule out” test because the rate of fetal fibronectin positivity was found to be higher in patients who gave birth via vaginal route. As also shown in our study, although there is no statistically significant difference, the pregnant women with shorter cervical length might have a high possibility to achieve vaginal delivery.
A decision support system for indirect potable reuse based on integrated modeling and futurecasting

Published: April 2019

Optimal operation of water reclamation facilities (WRFs) is critical for an indirect potable reuse (IPR) system, especially when the reclaimed water constitutes a major portion of the safe yield, as in the case of the Occoquan Reservoir located in Northern Virginia. This paper presents how a reservoir model is used for predicting future reservoir conditions based on the weather and streamflow forecasts obtained from the Climate Forecast System and the National Water Model. The resulting model predictions provide valuable feedback to the operators for correctly targeting the effluent nitrates using plant operations and optimization model called IViewOps (Intelligent View of Operations). The integrated models are run through URUNME, a newly developed integrated modeling software, and form a decision support system (DSS). The system captures the dynamic transformations in the nutrient loadings in the streams, withdrawals by the water treatment plant, WRF effluent flows, and the plant operations to manage nutrient levels based on the nitrate assimilative capacity of the reservoir. The DSS can provide multiple stakeholders with a holistic view for design, planning, risk assessments, and potential improvements in various components of the water supply chain, not just in the Occoquan but also in any reservoir augmentation-type IPR system.

Authors: Li Wunan , Liao Xiaoyong , Wang Lingqing , Huang Zhanbin
Published: April 2019

This study determined the adsorption of Cd2+ and Pb2+ (100 mg·L−1 of each) in simulated wastewater by biomass xanthates made from starch, chitosan, wheat stalk and corn stalk. The results showed that the adsorption efficiency of Pb2+ and Cd2+ ions followed the order: corn stalk xanthate > wheat stalk xanthate ≥ chitosan xanthate > starch xanthate. The results of kinetic modeling showed that the adsorption process was characterized by physical-chemical adsorption, and that a second-order kinetics equation described the adsorption process well. The optimum conditions for the adsorption of Cd2+ and Pb2+ by corn stalk xanthate were: adsorption time 2 hours, temperature 20–25 °C, and pH 6–8. The results serve as a reference for treating wastewater containing Cd2+ and Pb2+.

Spherical shape stability of shells and cavities
Authors: Ilgamov M.A.
Published: April 2019

Thin-walled shells characteristic of their light weight and strength are used everywhere – in household items to ocean liners and space rockets. Their applications are so diversified and uncountable that one can safely say, ”The world consists of shells; the world rests on shells.” After all, the Earth’s crust is also a shell. The wide application of thin-walled structures has triggered the need for developing reliable methods to calculate their strength and stability, and this is just the research subject of the shell theory, a new branch of mechanics arisen in the past century. The important role is found to be played by their interaction with working media. The present paper discusses the issues on the stability of spherical thin-walled shells and gas cavities in liquid.

Evolution of small sphericity distortion of a bubble in deuterated acetone with allowing for the vapor density effect
Authors: Toporkov D.Yu.
Published: April 2019

The evolution of a small distortion of the spherical shape of a vapor bubble during its single superstrong expansion and compression in deuterated acetone is studied. The spherical component of the vapor and liquid motion is governed by the hydrodynamics equations, allowing for nonequilibrium evaporation and condensation on the interphase surface. The non-spherical component of the interphase boundary motion is calculated taking into account approximate influence of the vapor density and inhomogeneity of the spatial distribution of the vapor pressure. It is found that the Rayleigh-Taylor instability is practically not appeared in the case with account of the vapor density influence whereas it has a significant effect on the shape of the bubble in the final part of its compression in the case with neglecting this influence.

Autoimmune Hepatitis and Stellate Cells: An Insight into the Role of Autophagy
Authors: Golbabapour Shahram , Bagheri-Lankarani Kamran , Ghavami Saeid , Geramizadeh Bita
Published: April 2019

Autoimmune hepatitis is a necroinflammatory process of liver, featuring interface hepatitis
by T cells, macrophages and plasma cells that invade to periportal parenchyma. In this process, a
variety of cytokines are secreted and liver tissues undergo fibrogenesis, resulting in the apoptosis of
hepatocytes. Autophagy is a complementary mechanism for restraining intracellular pathogens to
which the innate immune system does not provide efficient endocytosis. Hepatocytes with their
particular regenerative features are normally in a quiescent state, and, autophagy controls the accumulation
of excess products, therefore the liver serves as a basic model for the study of autophagy.
Impairment of autophagy in the liver causes the accumulation of damaged organelles, misfolded
proteins and exceeded lipids in hepatocytes as seen in metabolic diseases. In this review, we introduce
autoimmune hepatitis in association with autophagy signaling. We also discuss some genes and
proteins of autophagy, their regulatory roles in the activation of hepatic stellate cells and the importance
of lipophagy and tyrosine kinase in hepatic fibrogenesis. In order to provide a comprehensive
overview of the regulatory role of autophagy in autoimmune hepatitis, the pathway analysis of autophagy
in autoimmune hepatitis is also included in this article.
