Periodic law and system of chemical elements: 150 years from the date of discovery
Authors: Mikhailov Oleg V.
Published: June 2019

The data concerning the formulation of the Periodic Law and certain graphic variants of its interpretation, proposed at different times for 150 years from the moment of the opening of this law, have been presented and discussed. It was stated that, despite the presence of a very significant (several hundred) number of these variants, only two tabular versions of the Periodic Table of chemical elements, namely, the so-called “short-periodic” proposed by Dmitri Mendeleev and the so-called “long-periodic” proposed by Alfred Werner (which was recommended in the fullness of time by the International Union of Pure and Applied Chemistry), received practical applications. A modification of the indicated tabular variants, aimed at overcoming their shortcomings, has been proposed. The question of the existence of the upper boundary of the Periodic System and the probable prospects for obtaining super-heavy elements with a nuclear charge of Z > 110, in particular a new category of them – 5g-elements, has been also discussed.

Background and aims: Organizational support of family members of the patients admitted to intensive care units (ICUs) potentially reduces mental stresses and enables them to better comply with and support the patients. The current study aimed at evaluating the needs of families of the patients admitted to ICUs in teaching hospitals of Iran. Methods: This cross-sectional study was conducted in 2015 using convenience sampling method. The Critical Care Family Needs Inventory (CCFNI) in 5 factors was used as a main data collection tool. The study population included 235 family members of the patients. Results: Total score of CCFNI was 132.32±18.46. Needs of family members of ICU patients decreased 0.428 times following the increase of length of stay in ICU (P<0.001). Moreover, the need for supportive cares was significantly 9.273 times lower among illiterate families, compared with the ones with higher education level (P<0.018). Conclusion: Considering that the highest need was in the area of support and the predictors of the family needs of the patients were the duration of hospitalization and the educational status of their families, the main focus of nurses should be on the support of family members of the patients admitted to the ICU and supporting and paying attention to their needs, who experience stressful conditions, to satisfy them and even to encourage them to give better care to the patient and help health care staff.

Silver fir (Abies alba Mill.) is a keystone conifer of European montane forest ecosystems that has experienced large fluctuations in population size during during the Quaternary and, more recently, due to land-use change. To forecast the species’ future distribution and survival, it is important to investigate the genetic basis of adaptation to environmental change, notably to extreme events. For this purpose, we here provide a first draft genome assembly and annotation of the silver fir genome, established through a community-based initiative. DNA obtained from haploid megagametophyte and diploid needle tissue was used to construct and sequence Illumina paired-end and mate-pair libraries, respectively, to high depth. The assembled A. alba genome sequence accounted for over 37 million scaffolds corresponding to 18.16 Gb, with a scaffold N50 of 14,051 bp. Despite the fragmented nature of the assembly, a total of 50,757 full-length genes were functionally annotated in the nuclear genome. The chloroplast genome was also assembled into a single scaffold (120,908 bp) that shows a high collinearity with both the A. koreana and A. sibirica complete chloroplast genomes. This first genome assembly of silver fir is an important genomic resource that is now publicly available in support of a new generation of research. By genome-enabling this important conifer, this resource will open the gate for new research and more precise genetic monitoring of European silver fir forests.
Criterios ambientales y socioeconómicos para priorizar inversiones en la red vial de Costa Rica
Authors: Arias García Rodrigo , Rodríguez Morera José David
Published: June 2019

Dada la ausencia de la implementación formal de un Sistema de Gestión de Pavimentos para la Red Vial Nacional Pavimentada de Costa Rica, no han existido procesos de planificación de largo plazo sobre la inversión en los pavimentos de esa red. La presente investigación busca demostrar, además de la factibilidad de realizar planes de inversión de largo plazo (20 años) en pavimentos flexibles, también la posibilidad de utilizar índices ambientales, económicos y sociales como criterios de priorización.Para la elaboración de planes de inversión, se estimó la condición del pavimento a través de un índice compuesto por la capacidad funcional y la capacidad estructural, en cada sección de control de la Red Vial Nacional.A cada una de estas secciones se le agregó información de tránsito, jerarquía de la ruta y otras características. Posteriormente, se estimó empleando como referencia los costos de la licitación pública 2014LN- 000018-0C00, el valor de cada una de las intervenciones según la ventana de operación en que se encuentre el pavimento.Utilizando la herramienta informática Woodstock, se emplearon técnicas de optimización lineal para realizar escenarios de inversión incorporando diferentes criterios de priorización. De esta forma se emplearon el Índice de Progreso Social, el Índice de Competitividad Cantonal y la emisión de CO2, como criterios para priorizar las inversiones en las diferentes secciones de control de la Red Vial Nacional Pavimentada de Costa Rica.Con los resultados, es posible confirmar la factibilidad de elaborar planes de inversión de largo plazo a partir de los insumos disponibles en Costa Rica. Además, se observa que los aumentos de presupuesto tienen un mayor efecto en la rapidez con la que se alcanza una mejor condición de los pavimentos que en la condición en sí. Asimismo, la reducción de emisiones de CO2 tendrá un impacto en la condición de la red pues las intervenciones de reconstrucción son las que requieren actividades de mayor emisión de contaminantes.
Contexto de las especificaciones de regularidad superficial en proyectos de rehabilitación costarricense
Authors: Solís Salas Verónica
Published: June 2019

Para garantizar el desempeño del pavimento en proyectos de rehabilitación con sobrecapa asfáltica es necesaria la implementación de especificaciones técnicas, que permitan evaluar la calidad de la construcción. La aplicabilidad de las especificaciones debe ser validada en términos de valores logrados en proyectos previos, en conjunto con referencias de carácter internacional, donde ya hayan entrado en vigencia especificaciones similares y un seguimiento posterior para validar resultados. En el presente proyecto se analiza la aplicabilidad de las especificaciones establecidas en el Manual de especificaciones generales para la construcción de caminos y puentes de Costa Rica y los requisitos del cartel de licitación Nº.2014LN-000018-0CV00, para nueve proyectos en Costa Rica intervenidos con sobrecapa asfáltica en los últimos dos años. De la investigación se concluye que los rangos establecidos para las especificaciones costarricenses concuerdan con los establecidos en países como Chile, Colombia, España y Estados Unidos. Adicionalmente, los resultados mostraron que, pese a que tales especificaciones no eran vigentes en el cartel de licitación, se lograron cumplimientos aceptables, lo que indica la aplicabilidad de la normativa a la realidad costarricense. Finalmente, como producto de la investigación, se definieron mejoras a las especificaciones actuales que pueden ser verificadas posteriormente en los nuevos proyectos que entraran en ejecución.

Numerical simulation of the regime and geometric characteristics influence on the pressure loss of a low-flow aerothermopressor
Authors: Kobalava H. , Konovalov D.
Published: June 2019

In this paper, a study of gasdynamic processes that occur in a low-flow aerothermopressor has been done. The aerothermopressor is a two-phase jet apparatus for contact cooling, in which, due to the removal of heat from the air flow, the air pressure is increased (thermogasdynamic compression) and its cooling is taken place. Highly effective operation of the aerothermopressor is influenced by primarily the flow part design and the water injected method in the apparatus. Constructive factors that influence energy costs to overcome friction losses and local resistances on the convergent-divergent sections of the aerothermopressor are exerted a significant impact on the working processes in the apparatus. In this paper, a study of a number of typical low-flow aerothermopressor models has been conducted by using computer CFD modeling. Determination of the main parameters of the air flow (total pressure, dynamic pressure, velocity, temperature, etc.) has been carried out for a number of taper angles of a confuser a and a diffuser b, as well as for a number of values of the relative air velocity in the working chamber M = 0.4-0.8. Comparison of the obtained data with experimental data has been carried out. The deviation of the calculated values of local resistances coefficients in the confuser and in the diffuser from those obtained by computer CFD modeling does not exceed 7–10%. The recommended angles were determined: confuser convergent angle – 30° and diffuser divergent angle – 6°, corresponding to the minimum pressure loss is 1.0 – 9.5 %, and therefore also to the maximum pressure increase as a result of the thermogasdynamic compression that occurs during injection and evaporation of liquid in the working chamber. Thus, analytical dependences are obtained for determining the local resistance coefficients for the confuser (nozzle) and the diffuser, which can be recommended to use in the design methodology for low-flow aerothermopressors.
Сонячні абсорбційні системи кондиціювання повітря на основі двоступінчастої регенерації абсорбенту
Authors: Дорошенко О. В. , Антонова А. Р.
Published: June 2019

Розроблені принципові схеми багатофункціональних сонячних систем осушення повітря, теплопостачання (гарячого водопостачання та опалення), холодопостачання та кондиціювання повітря на основі відкритого абсорбційного циклу з прямою (безпосередньою) регенерацією абсорбенту. Такі системи базуються на попередньому осушенні повітряного потоку й наступному випарному охолодженні середовищ у сонячних холодильних системах (СХС) и термовологісної обробки повітря в сонячних системах кондиціювання повітря (ССКП). Авторами використовувався принцип двоступінчастої регенерації абсорбенту. Сонячна система складається з автономних осушно-охолоджувальних блоків, причому кожний ступінь регенерації замкнений на відповідний ступінь абсорбера-осушувача повітря, що дозволяє збільшувати концентрацію абсорбенту від ступеня до ступеня (у діапазоні можливих концентрацій використовуваного розчину бромистого літію LiBr). Розроблені принципові рішення для нового покоління газо-рідинних сонячних колекторів, що забезпечують безпосередню (пряму) регенерацію розчину абсорбенту. Робота тепломаcообмінних апаратів, що входять в осушувальний і охолоджувальний контури абсорбційних систем, базується на принципі плівкової взаємодії потоків газу й рідини з використанням багатоканальної структури із полімерних матеріалів для створення насадки. Попередній аналіз можливостей багатофункціональних сонячних абсорбційних систем виконувався на основі експериментальних даних авторів та моделювання процесів тепломасообміну в основних елементах систем, відносно завдань кондиціювання повітря (ССКП). Показано, що практично для будь-яких, «важких» параметрів зовнішнього повітря вирішення завдань забезпечення його комфортних параметрів може бути виконано без використання традиційної парокомпресорної техніки. Розроблені сонячні системи ССКП відрізняються малим споживанням енергії й екологічною чистотою.
Archaeological Studies of M.G. Moshkova in Orenburg Region in the 1950–1960s and Their Significance for the Volga-Ural Region Archaeology
Authors: Evgen’ev Andrey
Published: June 2019

The article considers the activity on studying archaeological sites of the Bronze Age, the Early Iron Age and the era of the Middle Ages in the east of Orenburg region performed by M.G. Moshkova in the 1950th – 1960th. The group of the Southern Ural archaeological expedition under the leadership of M.G. Moshkova investigated Novo-Kumakskiy and Alandskoe I-III burial grounds. Studying the monuments of the east area of Sauromatian culture allowed to specify borders of their distribution and to reveal manifestations of fire cult in the funeral ceremony. The article introduces the idea of formation of the South Ural early Sarmatian culture on the basis of Sauromatian culture with participation of tribes of the forest-steppe Trans-Ural region and the Aral region in this process. Also M.G. Moshkova revealed and investigated burial and settlement sites of Alakul culture that allowed to make adjustments in the periodization of Andronovo cultural and historical community. Studying the burials of medieval nomads in Novo-Kumakskiy burial ground led to specification of the periodization of South Ural history in the first half of the 2nd millennium BC. Thus, works of M.G. Moshkova in the east of Orenburg region promoted the solution of key problems of the Southern Cis-Ural and Trans-Ural history in the 2nd millennium BC – the 2nd millennium AD.

High and Low? The Heritage of Anglican Latitudinarianism in the Thought of John Wesley
Authors: Morris-Chapman Daniel Pratt
Published: June 2019

An increasing number of historians have highlighted the complex nature of much eighteenth-century churchmanship. These writers argue that in this period many clergyman possessed altitudinarian and latitudinarian tendencies simultaneously. While John Wesley's theological heritage has been examined from a variety of different perspectives, a growing body of literature has accentuated the altitudinarian tendencies in his theology and ministry. For this reason, several writers have closely identified Wesley with the Anglican High Church tradition. As a result, even though many of these scholars have compared Wesley's ecclesiology with the work of Edward Stillingfleet, the question as to whether or not Wesley might possess Latitudinarian tendencies has been neglected. Given the equivocal nature of much eighteenth-century churchmanship, this essay concentrates on whether Wesley also exhibits Latitudinarian tendencies by examining whether his focus on the essentials of religion, his tolerance concerning the inessential, and his emphasis on godliness resemble similar emphases in seventeenth-century Latitudinarian writers.
Criminal-Personal Features of Convicted Women of Childbearing Age in Russian Penitentiary Institutions
Authors: Muzychuk Tatyana , Kulakova Svetlana , Suslov Yury , Samoylova Anastasia
Published: June 2019

The paper discusses the criminological characteristics of convicted women in penitentiary institutions. It is based on the authors own observations, the analysis of disciplinary practices and crimes of convicted women and the reports of various departments of the Russian Federal Penitentiary Service in 2015-2017. Due to the social function of women, the problem of female crime and its prevention is currently urgent and requires a prompt solution. Most incarcerated women are of child-bearing age, some of them enter the penitentiary system already being pregnant, others become pregnant after extended visits by their husbands. The authors identify and analyze personal and criminological aspects of convicted womens behavior in the context of their motherhood. The paper stresses the behavioral characteristics of convicted women connected with motherhood in the conditions of isolation (the phenomenon of motherhood in the conditions of penitentiary isolation). The penitentiary system should provide the necessary conditions for mothers and their newborn children, which puts an additional specific burden on penitentiary systems employees responsible for achieving the goals of punishment, correction of inmates, observance of regime and prevention of repeat crimes.
The Institute of Monetary Penalties in Criminal Law: Condition and Prospects
Authors: Zvonov Andrei
Published: June 2019

Ever since the Criminal Code of the Russian Federation was adopted, new amendments have been added to it every year. Thus, the system of criminal law measures has been regularly improved through changes to the existing norms, the abolishment of old norms and the introduction of new ones. On the whole, modern Russian criminal policy is aimed at increasing the number of possible measures of influencing lawbreakers. One of the latest innovations is the institute of court fines introduced by the Federal Law № 323-ФЗ of July 3, 2016. It is a beneficial innovation. Monetary penalties can now be used practically at all stages of court procedures: before delivering a judgment - as a court fine, and as part of the sentence when a fine is a criminal penalty. This could have a positive impact on court procedures and the enforcement of criminal measures, it could also increase income to the budget in the unstable financial conditions. However, the imposition of monetary penalties has some drawbacks, as it may not be always possible to control the payment of fines by the perpetrators, especially when such payments are done one-time. There are some other issues and negative sides connected with the further development of the institute of monetary penalties. The analysis of penalties enforcement allowed the author to identify one vital drawback - a gap in the legal regulation regarding the control that a specially authorized agency has over the perpetrators. While this could be considered acceptable in the case of court fines, it is not adequate for the goals of criminal punishment. The results of the generalized analysis of punitive measures allow the author to conclude that it is necessary to make monetary penalty a measure that is different from criminal punishment; it should be enforced in cases of exemption from criminal liability or as an obligatory addition to criminal punishment.

The issues related to the problem of reducing unproductive water losses in the systems of cold and hot water supply of apartment buildings are considered in the article. The insufficient efficiency of application of known water saving devices, reducing overhead costs, the cause of which is the contradiction between the requirements of rationality and ensuring the maximum demand for a public water supply service, is shown. The recommendations for improving the design of the piston apartment pressure regulator “after itself”, ensuring a reduction in nonproductive costs are developed. The results of an experimental study of a pressure regulator with an improved water saving characteristic are presented.
Study of maternal and perinatal outcome among twin pregnancies with one twin demise
Authors: N. Sunanda , V. Akhila M.
Published: June 2019

Background: To study the incidence, management and to determine maternal and perinatal outcome in cases of twin pregnancy with one twin demise in the second half of the pregnancy.Methods: This retrospective study was carried out at Cheluvamba Hospital, a tertiary care hospital attached to Mysore medical college and research institute between September 2009 and 2014. 19 twin pregnancies complicated by single intrauterine fetal demise (IUFD) after 20 weeks of gestation were identified from the hospital records. Data collected included maternal age, parity, antenatal complications, cause of IUFD, gestational age at diagnosis, time interval between diagnosis of IUFD and delivery, mode of delivery, birth details, type of placentation and neonatal complications.Results: The incidence of twin with one twin demise was 2.056%. Mean gestational age at presentation was 33.86 weeks. Most common cause of death was growth discordance in 7 cases followed by placental insufficiency in 4 cases. 57.89% of cases had monochorionic placentation. Neonatal course was most commonly complicated by prematurity. Maternal course was uneventful in majority (63.15%) of cases with two maternal deaths due to intravascular coagulopathy sequelae.Conclusions: Single fetal death occurs more often in monochorionic twins. The main problem for the surviving twin is prematurity. It is very important to identify the chorionicity by ultrasound examination in early pregnancy and implement specific surveillance of monochorial pregnancies.

Introduction to NJWLS 2019-2
Authors: Buch Anders
Published: June 2019

This issue presents six new articles dealing with central issues in working life research in the Nordic countries. The articles all center around questions related to (the lack of) competencies and skills that are in demand in organizations and in relation to the labor market in general. They illuminate how skills – and skills gaps – are produced in complex dynamics of agency and structure, action and discourse, reflexive and deliberative subjective processes, and objective restraints, how labor market policies and organizational regulations affect working life, and how these policies in turn are counteracted. When I read the six articles, I was struck by the contradictory and often paradoxical nature of working life. The nuanced empirical studies of the six articles in this issue brings this out in fascinating detail. Let me just walk readers through the themes discussed (...)

The Truth and Reconciliation Commission of Canada: Insights into the Goal of Transformative Education
Authors: Czyzewski Karina
Published: June 2019

In 2006, the Government of Canada announced the approval of a final Residential Schools Settlement Agreement with the collaboration of the four churches responsible (United, Anglican, Presbyterian, Catholic), the federal government and residential school survivors. Schedule "N" of the Agreement lists the mandate of the TRC; therein, the TRC states one of its goals as: (d) to promote awareness and public education of Canadians about the system and its impacts. Can education - as the TRC hopes to engender - truly be transformative, renewing relationships and promoting healing in the process of forging these new relationships? The literature reviewed and the conferences attended highlighted that generating empathy may be a necessary ingredient for the instigation of social change, but is insufficient. Transformation through education, or reconciliation through truth-telling, testimonial reading and responsible listening would mean claiming a genuine, supportive responsibility for the colonial past. Educational policy and media initiatives are fundamental to creating awareness, developing public interest and support of the TRC's recommendations. However, authors also stress the importance of critical pedagogy in the whole process of truth and reconciliation, and that real reconciliation would require confronting the racism that initiated these institutions and allowed for a decontextualization of their impacts.

Objetivo: develar las vivencias de mujeres que utilizaron la medicina tradicional para afrontar los efectos de la quimioterapia y radioterapia en la ciudad de Lima. Material y métodos: Investigación cualitativa descriptiva interpretativa. Participaron 10 mujeres con cáncer a quienes se realizó una entrevista en profundidad previo consentimiento informado. Resultados: Emergieron cuatro categorías: I. Aceptando la enfermedad, II. Afrontando los efectos de la quimioterapia y radioterapia, III. Buscando la Medicina tradicional como alternativa y IV. Ser sobreviviente del cáncer. Conclusiones: Las mujeres al recibir el diagnóstico de cáncer experimentan cambios drásticos en su cuerpo como en su patrón habitual de vida, que las colocan como un “Ser vulnerable, frágil y dependiente”, este proceso termina con la aceptación de la enfermedad, lo que implica someterse a los tratamientos. Mientras reciben el tratamiento indicado por los médicos oncólogos, buscan la medicina tradicional, o a los médicos naturistas “Ser ayudados”, como consecuencia de ello modifican hábitos en la alimentación: disminuyen o suspenden el azúcar, la leche y todo alimento en base a frituras. Las plantas medicinales que suelen utilizar son: las hojas y la fruta de la Guanábana, la baba de la sábila; así como las infusiones en base de hierbas como la manzanilla, el cedrón y la yerba luisa. Las frutas secas y las uvas son muy usadas. Las carnes que prefieren son: el cuy, los pichones de paloma y el pescado. El “tocosh de la papa” en algunos fue rechazado por el olor. Uno de los minerales usado fue la “dolomita”.

Based on the geochemical analysis of the volcanic material from the sediment core AMK-340, central zone of the Reykjanes Ridge, we could detect two ash-bearing sediment units accumulated during the Termination I. They correlate to the Ash Zone I in the North Atlantic Late Quaternary sediments having an age of 12170-12840, within the Younger Dryas cold chronozone, and 13600-14540 years, within and Bølling-Allerød warm chronozone. The ash of the Younger Dryas unit is presented mostly by the mafic and persilicic material originated from the Icelandic volcanoes; Vedde Ash is presented in one sediment sample from this unit. The ash of the Bølling-Allerød unit is presented mostly by the mafic shards which are related to the basalts of the rift zone on the Reykjanes Ridge, having presumably the local origin. A detection of Vedde Ash helped to specify the timing of the previously reconstructed paleoceanographic changes for the Termination I in the point of study: a significant warming in the area could occur as early as 300 years prior to the end of the conventional Younger Dryas cold chronozone.

The vegan diet excludes animal-derived products consumption. The objective of the present study is to analyze dietary lipid intake, nine plasmatic fatty acids concentrations (from C14:0 [lauric acid] to C20:4 [arachidonic acid]), and conventional clinical lipid profile among vegan individuals with omnivore controls. A case-control and cross-sectional study was performed between 2016 and 2017. Vegans were paired in a 1:1 ratio with omnivores from Merida, Mexico. A 150-item Semi-Quantitative Food Frequency Questionnaire was conducted to evaluate eating patterns. Serum fatty acids were determined from total blood with a gas chromatography assay. Lower cholesterol, stearic, arachidonic and trans fatty acids intake, but higher consumption of lauric acid were observed in the vegan group (p= <0.001, 0.014, <0.001, 0.005, respectively). Decreased plasma concentrations of stearic, arachidonic and linoleic acids were found (p= 0.017, <0.001 and 0.026, respectively). Following a vegan diet for more than three years generate modifications in serum concentrations of saturated and polyunsaturated ω-6 fatty acids, which could lower inflammatory markers’ biosynthesis. Potential benefits regarding cardiovascular risk may be assumed in favor of vegan individuals.

Psychiatric disorders are mental, behavioral or emotional disorders. These conditions are prevalent, one in four adults suffer from any type of psychiatric disorders world-wide. It has always been observed that psychiatric disorders have a genetic component, however new methods to sequence full genomes of large cohorts have identified with high precision genetic risk loci for these conditions. Psychiatric disorders include, but are not limited to, bipolar disorder, schizophrenia, autism spectrum disorder, anxiety disorders, major depressive disorder, and attention-deficit and hyperactivity disorder. Several risk loci for psychiatric disorders fall within genes that encode for voltage-gated calcium channels (CaVs). Calcium entering through CaVs is key for multiple neuronal processes. In this review, we will summarize recent findings that link CaVs and their auxiliary subunits to psychiatric disorders. First, we will provide a general overview of CaVs structure, classification, function, expression and pharmacology. Next, we will summarize tools and databases to study risk loci associated with psychiatric disorders. We will examine functional studies of risk variations in CaV genes when available. We will review pharmacological evidence of the use of CaV modulators to treat psychiatric disorders. Our review will be of interest for those studying pathophysiological aspects of CaVs.

Penelitian ini bertujuan untuk mendapatkan perbandingan konsentrasi antara soya lesitin dan etanol agar menghasilkan etosom ekstrak etanol biji kopi hijau dengan efisiensi penjerapan terbaik serta mengetahui perbedaan permeasi antara gel etosom ekstrak etanol biji kopi hijau dan gel ekstrak etanol biji kopi. Ekstraksi biji kopi hijau dilakukan dengan metode maserasi menggunakan pelarut etanol 70%. Selanjutnya ekstrak diformulasikan dalam bentuk etosom menggunakan soya lesitin dengan konsentrasi yang divariasikan. Selanjutnya etosom diformulasikan dalam bentuk gel kemudian diuji laju permeasinya dan dibandingkan dengan gel ekstrak etanol biji kopi. Lipid yang digunakan adalah soya lesitin dan alkohol yang digunakan adalah etanol 95%. Perbandingannya dipilih berdasarkan formula yang paling banyak menjerap ekstrak etanol biji kopi hijau. Optimasi penjerapan dilakukan dengan menaikkan konsentrasi soya lesitin dan etanol hingga diperoleh penjerapan optimum. Pengujian permeasi dilakukan dengan sediaan gel etosom berbasis karbopol dan menggunakan kulit manusia secara in vitro. Berdasarkan hasil penelitian, diperoleh etosom ekstrak etanol biji kopi hijau dengan bentuk Large Unilamellar Vesicles (LUV) dengan ukuran 0,63–12,08 µm. Formula dengan perbandingan b/b soya lesitin : etanol (1:10) dapat menjerap ekstrak etanol biji kopi (EEBK). Uji permeasi menunjukkan bahwa total polifenol EEBK dalam sediaan gel etosom adalah 2,03 mg dalam waktu 240 menit dengan kecepatan lintas membran 1,37 mg/menit cm2. Sedangkan permeasi EEBK dalam sedian gel ekstrak adalah 3,12 mg dalam waktu 240 menit dengan kecepatan lintas membran 1,23 mg/menit cm2.

Increasing in frequency and impact in the United States and worldwide, disasters can lead to serious mental health consequences.

Although US census data are essential for disaster preparedness and the identification of community-level risk factors for adverse postdisaster mental health outcomes, the US Census Bureau faces many challenges as we approach 2020 Decennial Census data collection. Despite the utility of the information provided by the Census and American Community Survey (ACS), the 2020 US Census and subsequent ACS data face threats to validity.

As a result, public health funding could be misallocated, and disaster preparedness and response efforts misinformed; this can also contribute to the worsening of mental health inequities, particularly in the context of disaster. Undercutting the Census and the ACS, rich data sources that allow representation of all people in the United States, is a step backward in our effort to mitigate the population mental health consequences of disasters.
