On resonances under quasi-periodic perturbations of systems with a double limit cycle, close to two-dimensional nonlinear Hamiltonian systems
Authors: Kostromina Olga S.
Published: March 2021

The effect of multi-frequency quasi-periodic perturbations on systems close to twodimensional nonlinear Hamiltonian ones is studied. It is assumed that the corresponding perturbed autonomous system has a double limit cycle. Analysis of the Poincar´e–Pontryagin function constructed for the autonomous system makes it possible to establish the presence of such a cycle. When the condition of commensurability of the natural frequency of the corresponding unperturbed Hamiltonian system with the frequencies of the quasi-periodic perturbation is fulfilled, the unperturbed level becomes resonant. Resonant structures essentially depend on whether the selected resonance levels coincide with the levels that generate limit cycles in the autonomous system. An averaged system is obtained that describes the topology of the neighborhoods of resonance levels. Possible phase portraits of the averaged system are established near the bifurcation case, when the resonance level coincides with the level in whose neighborhood the corresponding autonomous system has a double limit cycle. To illustrate the results obtained, the results of a theoretical study and of a numerical calculation are presented for a specific pendulum-type equation under two-frequency quasi-periodic perturbations.

Authors: Mamonov Sergei S. , Ionova Irina V. , Kharlamova Anastasiya O.
Published: March 2021

In the article, the conditions for the existence of limit cycles of the first kind are obtained for self-tuning systems with delay, which, in turn, determine the conditions for the occurrence of hidden synchronization modes in such systems. The principle of the proof is based on constructing a positively invariant toroidal set using two cylindrical surfaces, whose boundaries are determined by the limit cycles of a system of the second-order differential equations. Using the results obtained in the article for limit cycles, the possibility of using the curvature of the cycle for a comparative analysis of the proximity of the cycles of phase and non-phase systems, as well as for determining the mode of hidden synchronization, is shown.

Published: March 2021

Introduction. Grinding sugar beet should be carried out with minimal losses in centrifugal beet cutters with specially designed knives that provide frequent and constant chaotic longitudinal-lateral cutting of circular conductive beet knots. The objective of the work is to increase the reliability of the knives of centrifugal beet cutters by structural and technological strengthening in the process of their production and restoration.
Materials and Methods. The state of the cutting edges of the knives was determined by using the micrometric measurement of the wear and deformation of the edges. Physical and mechanical indicators were analyzed based on the values of wear resistance, microhardness, and bending endurance.
Results. The analyzes of the defective state of the knives of centrifugal beet cutters and theoretical studies of the grinding process have allowed formulating the factors affecting the permeability of the beet chips and the efficiency of their grinding with knives of a special diamond-shaped design. Experimental studies have made it possible to establish dynamically substantiated design parameters of an improved knurled knife.
Discussion and Conclusion. The proposed measures ensured an increase in the durability of knives by 27–30%, the relative wear resistance of cutting edges by 20%, the limit of endurance of cutting edges for bending by 25% and a shift increase in the length of chips by 18–20% with an increase in its permeability by 16–18%.

Published: March 2021

Introduction. When carrying out an energy assessment of agricultural machines and traction tests of tractors, the most important indicator is the value of the tractive effort. The existing methods for determining the tractive effort of tractors imply the use of specialized measuring instruments, such as strain gauges and devices for processing and displaying information. The accuracy of determining the tractive effort is significantly influenced by the physical and mechanical properties of soil. To process the useful signal during the measurement of tractive effort, the data stream of the strain gauge sensor must be subjected to additional digital filtering taking into account the operating conditions of the agricultural unit. Materials and Methods. The functions of changing the tractive effort obtained on the K-744R2 tractor in various gears have been analyzed. An algorithm for digital processing of the signal of a strain gauge force meter based on a median filter has been developed that makes it possible to increase the measurement accuracy. The advantage of the proposed method is the ability to cut off sharp short-term impulse noise and sharp fluctuations in the amplitude of the measured value. Results. A method for determining the amount of tractive effort using median signal processing has been proposed. A device for determining the tractive effort during testing of agricultural tractors and units has been developed. The choice of the main components of the device for determining the magnitude of the tractive effort has been substantiated. As a result of the research, a device for measuring and digital processing of the signal of a force meter based on a microcontroller and specialized software for processing initial data in real time was designed and manufactured. Discussion and Conclusion. The developed method makes it possible to exclude the negative effect of impulse noise arising in the process of measuring the tractive effort of the tractor. The proposed device for measuring the tractive effort of tractors is compatible at the level of the exchange protocol with existing devices, has a high speed of operation in real time, multi-channel operation.

Martensitic transformation in the systems based on Fe-Ni compositions in strong pulsed magnetic fields
Authors: Zolotarevskii I.
Published: March 2021

Purpose of work. To ascertain the causes of the abnormally large displacement of the martensitic point in steels and iron alloys in strong pulsed magnetic fields at low temperatures.
Research methods. Generalization of experimental and theoretical investigations of the strong magnetic field influence on the martensitic transformation in steels and iron alloys, taking into account the magnetic state of austenite.
The obtained results. The distributions of the martensitic point displacement ΔMS from the content of the main component - iron and the temperature of the martensitic γ → α- transformation beginning (martensitic point MS) in
different experiments are obtained. It is shown that the obtained temperature dependence ΔMS(MS) in a strong magnetic field at low temperatures decomposes into two components, one of which correlates with the generalized Clapeyron-Clausius equations, and the other is opposite to it. In addition, it was found that steels and alloys with intense γ → α- transformation in a magnetic field contain at least 72.5% iron (wt), which at low temperatures in the fcc structure is antiferromagnetic.
Scientific novelty. The anomalous temperature dependence of the distribution ΔMS(MS) in a strong magnetic field is explained on the basis of quantum representations of the magnetic interaction of atoms in the Fe-Ni system. This effect is associated with a number of other invar effects, in particular, with an abnormally large spontaneous and forced magnetostriction, a strong dependence of the resulting exchange integral on the interatomic distance. The point of view according to which in these alloys in a magnetic field γ → α- transformation occurs by the type of “magnetic first kind phase transformation” is substantiated. It is assumed that the nucleation of the martensitic phase in a magnetic field occurs in (at) local regions of γ- phase with disoriented atomic magnetic moments (with high compression and increased forced magnetostriction).
Practical value. The information obtained in this work provides grounds for explaining the kinetic features of the transformation of austenite into martensite in steels and iron alloys.

Published: March 2021

Purpose of work. To investigate the features of microscopic kinetics of peritectoid transformation in Fe-Mo system alloys in an isothermal mode.
Experimental part. Microscopic analysis of samples on light (Jenaphot 2000, K. Zeiss) and scanning electron (REM 106I, Selmi) microscopes, X-ray spectral microanalysis of the component’s concentrations distribution between the phases, X-ray phase analysis (Rigaku Ultima IV diffractometer).
Results. Microstructure changes, phase composition and crystal lattices parameters of the phase constituents of the powder alloy during sintering at 920 °C were investigated. Variation in the phase constituents mass fraction during 7 hours of the isothermal exposure is analyzed. The formation of anomalous diffusion porosity at the beginning of the process, the nonmonotonic change in the phase constituents fraction and formation of intermediate phases with an unstable component’s concentration are the main features of the microscopic kinetics. The sintering mechanism is proposed.
Scientific novelty. A local peritectoid transformation existence at the Fe/Mo interface was established by analyzing the local diffusion flows of components atoms. This transformation occurs upon isothermal supply of Mo atoms with the formation of a cooperative peritectoid structural constituents according to the α- Fe + Mo → α + μ scheme with residual Mo crystals.
Formulation of the problem. This work aims to clarify the phenomenological theory of peritectoid transformation during isothermal α-Fe grains enrichment with molybdenum by studying the features of microscopic kinetics in the Fe-Mo system alloys.
Practical value. Peritectoid (α + μ) with branched phase соnstituents of cooperative genesis forms a developed system of local diffusion flows of Mo atoms in α -Fe. This increases the molybdenum peritectoid transformation rate at a relatively low sintering temperature for these alloys and reduces the energy consumption in the technological process.
Relationship between seismicity and active faults in Thanh Hoa province detected by local seismic network
Authors: N. Duong T. , Phong Lai Hop , N. Pham D. , H. Chen C. , T. Dinh V.
Published: March 2021

Thanh Hoa province belongs to the southwest part of Northwest Vietnam, which is considered a tectonically active region. In the area of Thanh Hoa province, there are three deep-seated tectonic faults, namely Son La-Bim Son, Song Ma, and Sop Cop. As predicted by scientists, these faults are capable of producing credible earthquakes that might be the strongest in the territory of Vietnam. Besides the three main seismogenic sources, in the province, there are other smaller active faults such as Thuong Xuan-Ba Thuoc and Thuong Xuan-Vinh Loc but the relationship of these faults with seismic activity is still rather blurred. This may due to the sparseness of the Vietnamese National Seismic Network which can not record adequately small earthquakes in the area. This paper presents new results of additional monitoring from a local seismic network using 12 Guralp - 6TD broadband seismometers that have been deployed in Thanh Hoa province since November 2009. We found that the Thanh Hoa area is not seismically quiet. The average number of earthquakes recorded by the network has reached 80 - 90 events per year and some of them have magnitude from ML 3.0 to 4.0.By integration of the earthquake epicenters derived from the local network and distribution of active faults, we can detect several earthquakes locating near the three active faults, not only along the main faults but also along its subsidiary faults. We focused on the active faults of Thuong Xuan-Ba Thuoc and Thuong Xuan-Vinh Loc by using the recent results of the gravity, seismic, and magnetotelluric data analyses. Several recorded earthquakes distribute along the two small faults and some of them reach magnitude 3.0 or greater on the ML scale. In this study, the Thuong Xuan-Vinh Loc is recognized as a seismogenic source. To identify seismic hazard potential caused by earthquakes generated from the active faults, segmentation of the Thuong Xuan - Ba Thuoc fault had been done based on geological and geomorphological indications and seismic activity, and then the peak ground acceleration was determined for each fault segment. Besides, a large number of earthquake epicenters do not have a good correlation with a specific fault, especially in the area of Thanh Hoa coastal plain, which is covered by thick layers of Neogene - Quaternary sediment. This shows that there may be hidden active faults in the area which are needed to study further.

Published: March 2021

Nineteen sites with 198 oriented-core samples have been collected from the Upper Permian-Lower Triassic volcanic rocks of Vien Nam Formation at Quynh Nhai locality, Son La Province, northwestern Vietnam. The characteristic remanent magnetization components carried by magnetite and hematite were successfully isolated from secondary components reveal a mean paleomagnetic direction Ds = 48.3°, Is = -10.0°, a95 = 8.0°, corresponding to a virtual geomagnetic pole located at l = 35.7°N, f = 217.4°E and a paleo-latitude of study area situated at 5.1°S during the Permian time. Compared with the Late Permian-Early Triassic pole of the South China Block (SCB), the data show that crustal elements of NW Vietnam have been close to, but not unequivocally a coherent part of the SCB, since the Late Permian. Development of the parallel NW-SE striking Song Ma and Song Chay orogenic belts did not involve the closure of wide (> 500 km) ocean basins.

Authors: B. Longpia C.
Published: March 2021

The PVL springs are used for both domestic and agricultural purposes. The seepage from the springs has resulted in producing a large expanse of wetlands and is therefore intensively use for dry season farming. The aim of this study was to determine the hydrogeological, hydrochemical characteristics, origin and their suitability for domestic and irrigation. The hydrogeology of the springs was determined by field mapping. The physico-chemical parameters were determined in the field and by laboratory methods. For the cation and anion analysis the ICP-MS and the wet methods were employed respectively. The stable isotope composition of oxygen (δ18O) and hydrogen (δ2H) were analyzed by Isotope Ratio Mass Spectrometer. The hydrochemical analysis revealed that the PVL springs waters are generally neutral with an average pH value of 7.3. The average TDS and EC values are 127.8mg/l and 246µs/cm respectively. These values fall within fresh water class. The average Mg2+,Ca2+, Na+ and K+ cation concentration values are 16.3mg/l, 15.8mg/l, 10.8mg/l and 5.58mg/l respectively. The average anions concentration of HCO3-, SO4 and Cl- are 140mg/l, 8.6mg/l and 3.4mg/l respectively. Piper trilinear diagram show that the spring waters is predominantly Mg-Ca-HCO3 water type with potable qualities based on WHO drinking water standards. The sodium Adsorption Ratio (SAR) and Sodium Soluble Percentage (SSP) values range between 0.44 to 0.84 and 26.4 to 54% respectively and falls within irrigation quality standards. Stable isotope compositions of δ18O and δ2H ranges from -3.60/00 to -4.90/00 and -200/00 to -280/00 respectively falls within the meteoric water composition. This is further affirmed by the δ2H versus δ18O plot on the correlation diagram with Standard Meteoric Water Line.

Vaccination of the population is one of the most effective countermeasures in responding to the pandemic caused by novel coronavirus infection. Therefore, scientists all over the world have been working to develop effective and safe vaccines. We have developed a synthetic peptide vaccine, EpiVacCorona, against novel SARS-CoV-2 coronavirus, which is a suspension for intramuscular administration containing a composition of chemically synthesized peptide immunogens of the S protein of SARS-CoV-2 coronavirus conjugated to a carrier protein and adsorbed on aluminum hydroxide. Phase I–II clinical trials of the vaccine have started that consist of two stages: Stage 1 is an open study of the safety, reactogenicity, and immunological activity of the vaccine with the involvement of 14 volunteers aged 18–30 years; Stage 2 is a single blind, comparative, randomized placebo-controlled study with the involvement of 86 volunteers. The study involved volunteers aged 18–60 years; the vaccine was injected intramuscularly twice, spaced 21 days apart between injections. All local reactions in response to vaccine administration were mild, such as a short-term pain at the injection site. There were no signs of development of local or systemic adverse reactions. The two-dose vaccination scheme induced the production of antibodies, specific to the antigens that make up the vaccine, in 100% of the volunteers. Seroconversion with a neutralizing antibody titer ≥ 1:20 was reported in 100% of the volunteers 21 days following the second immunization dose. No seroconversion was reported in the groups of volunteers vaccinated with a placebo. The peptide-based EpiVacCorona Vaccine has low reactogenicity and is a safe, immunogenic product. Clinical Trials Identifier: NCT04527575.

ABSTRACT Objectives: to understand how the therapeutic itineraries of people affected by leprosy are processed. Methods: this is a descriptive, qualitative study, conducted in April 2018 in Barão de Grajaú in Maranhão, with interviews in the form of narratives of seven patients who had a late leprosy diagnosis. Results: the search for diagnosis is a major difficulty in accessing health services, resulting in a late diagnosis and, consequently, with the presence of visible deformities. It was noticed that the health units do not have a flow, nor protocols for comprehensive treatment, and these people are referred to a referral unit in another state to perform sputum smear microscopy. Final Considerations: leprosy control actions need reformulations that seek the relationship between operational activities, epidemiological indicators and risk factors, in accordance with the real needs of each region, thus highlighting the gaps evidenced in the therapeutic itineraries.

ABSTRACT Objective: the aim of this study was to identify associated factors with the increased length of hospital stay for patients undergoing surgical treatment for liver trauma, and predictors of mortality as well as the epidemiology of this trauma. Methods: retrospective study of 191 patients admitted to the Cajuru University Hospital, a reference in the treatment of multiple trauma patients, between 2010 and 2017, with epidemiological, clinicopathological and therapeutic variables analyzed using the STATA version 15.0 program. Results: most of the included patients were men with a mean age of 29 years. Firearm injury represents the most common trauma mechanism. The right hepatic lobe was injured in 51.2% of the cases, and hepatorraphy was the most commonly used surgical correction. The length of hospital stay was an average of 11 (0-78) days and the length of stay in the intensive care unit was 5 (0-52) days. Predictors for longer hospital stay were the mechanisms of trauma, hemodynamic instability at admission, number of associated injuries, degree of liver damage and affected lobe, used surgical technique, presence of complications, need for reoperation and other surgical procedures. Mortality rate was 22.7%. Conclusions: the study corroborated the epidemiology reported by the literature. Greater severity of liver trauma and associated injuries characterize patients undergoing surgical treatment, who have increased hospital stay due to the penetrating trauma, hemodynamic instability, hepatic packaging, complications and reoperations.

Abstract: The Atlantic Forest north of the São Francisco River, known as the Pernambuco Endemism Center (PEC), comprises small, poorly-known and, consequently, highly threatened forest remnants, such as Refúgio de Vida Silvestre (RVS) Matas do Siriji, a montane forest located in the municipality of São Vicente Férrer, state of Pernambuco, Northeast Brazil. We provide the results of the first inventory of the squamate fauna of the region with comments on the conservation status of some species, comparisons with other locations in Northeast Brazil and a brief discussion of biogeography. Time-constrained transects, pit-fall traps, occasional encounters and third-party records registered 18 lizard species and 25 snake species, with the rarefaction curve of the former tending to stability. The RVS Matas do Siriji possesses 39.81 % of the lizard and snake species known for the state of de Pernambuco, being the third richest area in species in the State, with a composition similar to that of other areas within PEC. Based on the lists of SEMAS, ICMBio and IUCN, some of the registered species are considered vulnerable to extinction while others have yet to be evaluated. The RVS Matas do Siriji includes a rich, threatened and underestimated fauna of squamate reptiles, indicating that more restrictive protection measures must be adopted in this Conservation Unit.

Published: March 2021

Abstract This article introduces the special issue reflecting on the influence of the book Material culture and mass consumption by Daniel Miller on interdisciplinary debates in social science in Brazil. Here we review the main arguments presented in the book - yet to be translated into Portuguese - while also considering some of the criticism it has received in past decades. Next, we present the connection between Miller’s theory of consumption and his wide-ranging work in digital anthropology. Afterwards, we introduce the four original papers contained in this special issue and which consider, based on empirical research, the on-going relevance of Miller’s theory to current debates on materiality, social media and interdisciplinary exchange, including an interview with the author. Finally, in this introduction, we also present the section Registros de Pesquisa, where different Brazilian researchers discuss the opportunity of working closely with Miller.

A primeira refere-se à discussão de que a obrigatoriedade da pré-escola veio no bojo de outras leis que ampararam o ensino fundamental de nove anos e, por conseguinte, o encurtamento do período dedicado à educação infantil e às questões que envolvem o exercício de vivência do direito à infância das crianças. A segunda relaciona-se às agendas dos organismos multilaterais que buscam por intermédio do status conferido a determinadas evidências científicas, sobretudo àquelas advindas das neurociências, vincular a frequência na pré-escola a um bom resultado no ensino fundamental.  A terceira apresenta as principais estratégias que os municípios lançaram mão para o alcance da universalização da pré-escola, entre elas o aumento dos convênios, a inserção de turmas de pré-escolas em escola de ensino fundamental, a oferta em turno parcial e a privatização da educação.

Quo vadis erdészeti szaporítóanyag-termesztés? II. : Erdészeti szaporítóanyag-termesztés a II. világháború után
Authors: Frank Norbert , Lett Béla
Published: March 2021

A II. világháború után megkezdődött a központilag szervezett szaporítóanyag-gazdálkodás szervezése, kialakítása. A magántulajdonú csemetekerteket felváltották az állami erdőgazdaságok kis vándorcsemetekertjei, melyek a szükséges szaporítóanyagot az erdőfelújítások és erdőtelepítések közelében termelték meg. Az 1955-ben kiadott Csemetetermelési utasítás már a minőségi csemetetermelés gyors javítását tűzte ki célul, ennek érdekében megkezdődött a csemetetermelés koncentrálása, melynek következtében az 1949 és 1979 között a regisztrált csemetekertek száma 1126-ról 566-ra csökkent. Tanulmányunk célja ezen időszakra vonatkozó csemetetermelési és -felhasználási tendenciák elemzése, egyes fafajokra, fafajcsoportokra vonatkozó adatok, változások elemzése. Összességében megállapítható, hogy a vizsgált időszakban jelentős mértékben csökkent a csemetekertek száma, változott a megtermelendő fafajok mennyisége, aránya, és mindezeket az időbeni egyenetlenség jellemzi. Az általunk vizsgált tervgazdálkodásos időszakban az évente megtermelt és felhasznált csemeték mennyiségének különbsége átlagosan 66,89 millió darab volt; a termelési többlet az 1975-ös évben érte el a legalacsonyabb értéket (21,1 millió darab). A vizsgált periódus átlag bruttó csemetekerti területe 3396 hektár; az átlag csemetekerti területnagyság viszont az 1954-1959-es 2,55-2,26 hektárról az időszak végére (1979) elérte a 5,45 hektárt, azaz az időszakra jellemző átlagterületet (3,5 hektár) 1,95 hektárral meghaladta.
Különböző erdészeti beavatkozások hatása egy gyertyános-tölgyes avartakarójára

A Pilis Üzemmód Kísérlet keretében különböző kezelések (tarvágás, bontóvágás, hagyásfacsoport, lékvágás) avar mennyiségére és kémhatására gyakorolt hatását vizsgáltuk. A jelen publikációban ismertetett négyéves időszak alatt a kontrollállományok avarviszonyai nem változtak, ugyanakkor a kezelések az általunk vizsgált mindhárom avarváltozót (tömeg, nedvesség, kémhatás) jelentős mértékben befolyásolták. Az avartömeg a hagyásfacsoportban volt a legmagasabb, azonban ez a terület bizonyult a legszárazabbnak is. A legkevesebb avarmennyiséget a tarvágásokban mértük. A kezelések legerősebb hatással az avar kémhatására voltak: a tarvágásban és kismértékben a lékekben is megemelkedett a pH, amit a megváltozott aljnövényzet eredményezett. Eredményeink alapján megállapítható, hogy a kismértékű bontás nem okoz változást az avarviszonyokban, a hagyásfacsoportok hatékonyan ellensúlyozzák a vágásterületek megváltozott avarviszonyait, illetve a lékek sokkal kisebb mértékben változtatják meg az avarviszonyokat, mint a vágásterületek. Ezek alapján megállapítható, hogy a finom léptékű beavatkozásokon alapuló örökerdő üzemmód kedvezőbb avarviszonyokat biztosít, mint a vágásos erdőgazdálkodás.

Yıldırma hem bireysel hem grupsal etki açısından negatif sonuçları olan soyut ve karmaşık bir yapıdır. Çalışma alanında uygulanan yıldırma, daha çok hem çalışan üzerinde hem de başkalarına karşı yapılan; tahammülsüzlük, psikolojik yıldırma, düşüncülere baskı kurma, farklılıklara karşı kabullenmeme gibi durumlardır. Bu çalışmada yıldırmanın Özel okul öğretmenlerin motivasyonu üzerindeki etkilerine değinilmiş ve bu etki açıklanmaya çalışılmıştır. Araştırmamıza 14 erkek, 27 kadın olmak üzere toplam 41 kişi gönüllü olarak katılmıştır. Bu araştırma, yöntem olarak nicel tarama modeli ve kesitsel tarama tasarımına dayalı olarak hazırlanmıştır. Verilerin elde edilmesinde ‘İş yerinde psikolojik taciz ölçeği’ ile ‘Kişisel Bilgi Formu’ kullanılmıştır. Normallik testi için Kolmogrov-Smirnov (KS) testi uygulanmıştır. P değerleri 0,05 ten küçük çıkmıştır. Bu durum verilerin normal dağılmadığını göstermiştir. Daha sonra betimsel analiz yapılarak frekans, ortalama ve yüzde değerleri hesaplanmıştır. Normal olmayan dağılımlarda paremetrik olmayan analizler yapılır (Yıldırım & Şimşek, 2016). İki değişkenli kategorik bağımsız değişkenlerimiz olan cinsiyetin bağımlı değişken üzerindeki etkisi Mann-Whitney U testi ile analiz edilmiştir. Beş değişkenli olan hizmet süresi ve yaş ile on değişkenli olan branş değişkenlerinin etkileri ise Kruskal – Wallies testi ile yapılmıştır. 28 bağımlı değişken üzerinde; cinsiyet, hizmet süresi, yaş, ve branşa göre anlamlılık ilişkisi aranmıştır. Analiz sonuçları bize yıldrmanın çok düşük miktarda olduğunu göstermiştir. Erkeklerin kadınlara göre, matematik branşının diğer branşlar göre, işe yönelik davranışlar açısından sınıf öğretmenliği branşı diğer branşlara göre, daha fazla, yıldırmaya maruz kalmıştır. Yine benzer şekilde dışlayan davranışlar ile sözlü, yazılı ve görsel saldırılar açısından matematik branşının daha fazla yıldırmaya maruz kaldığı görülmektedir. Hizmet süresi ve yaş değişkenlerine göre boyutlar arsında ve ölçeğin ortalamasında anlamlı farklar bulunmamıştır.

Authors: Araya Alejandra-Ximena , Iriarte Evelyn
Published: March 2021

Objective. The study sought to compare community-dwelling older people with respect to their level of physical activity and to the fear of falls between a group of sedentary elderly and a group of active elderly.

Methods. Cross-sectional descriptive study carried out with 113 community-dwelling older people (45 sedentary and 48 active), users of an outpatient care center of the private health system with a geriatric program in Santiago, Chile. The study measured socio-demographic variables, state of health, comprehensive geriatric assessment, exercise, depression with the Yesavage scale, and fear of falling with the Short Falls Efficacy Scale - International (Short FES-I).

Results. Sedentary older people have significantly higher scores in the Yesavage depression scale compared with active older people (4.2 versus 0.8). No statistically significant differences were found when comparing both groups of sedentary and active participants in terms of socio-demographic variables along with health, and functional and cognitive capacity. Regarding the fear of falling, the sedentary had a slightly higher score than the active (12 versus 11), although not significant.

Conclusion. This study showed that fear of falling was equal in sedentary and active older people who live in the community, although it was found that sedentary individuals had a higher risk of having a positive screening for geriatric depression in those participants who do not perform physical activity.

Published: March 2021

Rawadanau is a tropical mountain swamp located in Serang, Banten, Indonesia. Rawadanau groundwater is the main source of supply for the Cilegon Banten industrial area. Knowing the origin and quality of the groundwater can help preserve existing resources. This paper aims to clarify the origin of Rawadanau groundwater with new evidence of stable isotopes (18O and 2H) and hydrochemical data. Field measurements included pH, temperature, EC, HCO3ˉ, while the analyses of cations, anions and stable isotopes were carried out in the laboratory. The existing water supplies include springs, excavated wells, and river water. Cluster hierarchy analysis based on water chemistry and stable isotopes can be grouped into two clusters, cluster K (K1 and K2) and cluster L. Data δ18O and δ2H springs in Rawadanau indicate that they are of meteoric origin and that there has been evaporation from several springs. Water comes from meteoric water with a stable isotope content of δ18O between -6.39 to -4.82 ‰ and δ2H between -41.35 to -31.30 ‰, which are controlled by two main mechanisms, namely rock dissolution and evaporation dominance. Aquifers are composed of volcanic rocks with a dominant composition of porphyritic andesite, basaltic andesite, and andesite. According to the multivariate statistical analyses results other than pH and SO4 2-, all parameters (cations and anions) showed a significant correlation. There are four hydrochemical facies of groundwater, namely Ca-HCO3, Ca-Mg-HCO3, Mg-Ca-HCO3, and Na-Cl.
