Public Response to Urban Forest in Inner-City Business Districts
Authors: Wolf Kathleen
Published: February 2022

Revitalization programs are under way in many inner-city business districts. An urban forestry program can be an important element in creating an appealing consumer environment, yet it may not be considered a priority given that there are often many physical improvements needs. This research evaluated the role of trees in consumer/environment interactions, focusing on the districtwide public goods provided by the community forest. A national survey evaluated public perceptions, patronage behavior intentions, and product willingness to pay in relationship to varied presence of trees in retail streetscapes. Results suggest that consumer behavior is positively correlated with streetscape greening on all of these cognitive and behavioral dimensions. Research outcomes also establish a basis for partnerships with business communities regarding urban forest planning and management.
Dynamic Loading of Trees
Authors: James Ken
Published: February 2022

The dynamic forces on tree structures during periods of high winds is being studied in order to determine the loads on trees and the responses of the trees to those dynamic loads. Field measurements of dynamic forces on trees, branches, and cables have been conducted on urban trees in an attempt to quantify the magnitude of these forces and to provide a basis for evaluating tree stability. Equipment was constructed to measure the dynamic wind loads on tree trunks and branches in situ. This equipment is described, and results are presented which indicate that tree structure is loaded by highly variable wind gusts and responds by behaving in a complex dynamic manner, which minimizes the energy transfer from the wind to the tree structure. The dynamic response of the tree involves a complex interaction of the natural frequencies of each component of the tree, including the trunk, main branches, sub-branches, and smaller sections. A dynamic model of trees is presented and includes mass damping that minimizes the sway energies and combines with the drag forces of the canopy to help the tree cope with large wind forces. A discussion of windthrow and tree dismantling is presented, based on the information collected from these studies.
Identifying Plant Communities Resistant to Conifer Establishment Along Utility Rights-of-Way in Washington and Oregon, U.S.
Authors: Shatford Jeff , Hibbs David , Norris Logan
Published: February 2022

A program to assess the utility of stable, low-growing plant communities in suppressing conifer seedling establishment along electrical rights-of-way was initiated in the states of Washington and Oregon, U.S., in 1999. The percentage of cover of all woody species and density of tree stems was described at three sites by sampling 1,376 plots, each 2 ´ 2 m. We asked if tree seedlings, principally Douglas-fir (Pseudotsuga menziesii), were distributed randomly among community types defined by growth form and percentage of cover. Douglas-fir seedlings were not randomly distributed and occurred less frequently within communities already occupied by dense vegetation. This included some, but not all, low-growing communitiese.g., areas of dense grass or shrub communities of moderate to high cover. Douglas-fir seedlings were infrequent within patches dominated by trees and tall shrubs, but these do not fit the low-growing requirement of the program. Of particular concern to vegetation managers was the large number of Douglas-fir seedlings that regrew from an uncut lateral branch.
Examining Formulas That Assess Strength Loss Due To Decay In Trees: Woundwood Toughness Improvement In Red Maple(Acer rubrum)
Authors: Kane Brian C.P. , Ryan H. Dennis P.
Published: February 2022

Hazard trees are a concern for anyone who manages trees in a landscape setting, including arborists, urban foresters, and grounds managers. Through research, experience, observation, and common sense, arborists and urban foresters have identified many risk factors that predispose trees to failure. They have also developed thresholds to help determine the degree of hazard, whether a tree is in imminent danger of failing or needs annual (or more frequent) inspections. Two critical factors are involved in strength loss assessment in tree stems with defects. First, it is important to know how much tree strength is lost due to a defect such as a hollow or cavity. Second, the load required to cause failure needs to be considered since the wood of some trees can endure greater mechanical stress than others. Tests of woundwood and normal wood in red maple(Acer rubrum)trees from Massachusetts, U.S., showed woundwood to exhibit consistently greater toughness measures compared to normal wood. There was, however, no correlation between the degree of toughness improvement in woundwood and the severity of decay (calculated as the loss in moment of inertia of the stem). Woundwood toughness improvement appears to be an additional safety factor in red maple trees that reduces the risk of failure due to trunk decay.
Branch-To-Stem Diameter Ratio Affects Strength of Attachment
Authors: Gilman Edward F.
Published: February 2022

Strength of branch attachment inAcer rubrumL. was related to the ratio of diameter of the branch relative to the diameter of the stem to which the branch was attached (aspect ratio). Linear correlation coefficients ranged from –0.25 to –0.90 between aspect ratio and load (force) required to separate branches from stems at the branch union. Slopes of the lines describing this relationship increased with increasing branch diameter. This indicated that larger branches required greater force to pull them from the trunk provided they were small compared to the trunk. However, diameter had less of an influence on force required to pull codominant stems apart. Force per unit of branch cross-sectional area was related (R2= 56%) to aspect ratio, indicating that a branch of a given size was better secured to the tree if it was attached to a much larger stem than to a stem of equal size. Angle of attachment was not related to strength of branch attachment. Codominant stems were far easier to split apart than branches that were small relative to stem size. Codominant stems broke by separating at the union; branches failed by breaking at or near the collar. This information has implications for arborists climbing trees and will help guide development of pruning strategies.
How Urban Residents Rate and Rank the Benefits and Problems Associated with Trees in Cities
Authors: Lohr Virginia , Pearson-Mims Caroline , Tarnai John , Dillman Don
Published: February 2022

Residents of the largest metropolitan areas in the continental United States were surveyed about the benefits and problems of trees in urban areas. The public rated the social, environmental, and practical benefits of trees highly. The ability of trees to shade and cool surroundings was the highest-ranked benefit. Their potential to help people feel calmer was ranked second highest. Potential problems with trees were not considered to be reasons not to use trees. Practical problems, such as causing allergies, were bigger concerns than were financial issues. People who strongly agreed that trees were important to their quality of life rated the benefits of trees more highly than people who did not strongly agree. Those who strongly agreed and those who did not strongly agree ranked the benefits and problems similarly. Responses varied slightly based on demographic factors. For example, those who did not strongly agree that trees were important to life quality were more likely than expected to be 18 to 21 years old or to earn US$20,000 or less per year. The general public in urban areas, not just people who volunteer for tree programs, felt very positively toward trees in cities.
Drought Stress and Paper birch(Betula papyrifera)Seedlings: Effects of An Organic Biostimulant on Plant Health and Stress Tolerance, and Detection of Stress Effects with Instrument-Based, Noninvasive Methods
Authors: Richardson Andrew D. , Aikens Melissa , Berlyn Graeme P. , Marshall Philip
Published: February 2022

We conducted a progressive-drought greenhouse experiment, using potted paper birch (Betula papyrifera) seedlings in their third year of growth, to investigate whether a commercially available organic biostimulant improved plant health and stress tolerance, and to compare four noninvasive, instrument-based methods for monitoring plant stress. In the well-watered (no drought) plants, the biostimulant application significantly increased foliar nitrogen concentrations (P = 0.01) and led to marginally higher rates of photosynthesis (P = 0.10) and slightly higher Fv/Fmfluorescence ratios (P = 0.14). Reflectance indices further indicated that the biostimulant application resulted in increased chlorophyll content (Chl NDI, P = 0.07) and either (depending on interpretation) a significantly higher Chl:carotenoid ratio or a lower proportion of xanthophyll cycle pigments in the de-epoxidated state (PRI, P = 0.02). The PRI results suggest less oxidative stress in the treated plants, which may be related to the fact that the biostimulant used (Roots 3) contained ascorbate, an antioxidant. In the plants exposed to progressive drought, the biostimulant application had similar effects but did not appear to dramatically improve the drought stress tolerance of seedlings, in that impaired physiology occurred at about the same level of soil moisture in both treated and untreated seedlings. Photosynthesis responded to the drought treatment at about 12% to 15% soil moisture content (SMC), whereas PRI did not respond until about 9% to 10% SMC, and Fv/Fmdid not respond until about 4% to 5% SMC. Chl NDI did not show a significant response to SMC.

O Brasil é reconhecido mundialmente pelo seu excelente desempenho econômico e produtivo nos setores agropecuários. Com o crescimento da demanda mundial por alimentos o país ampliou sua área produtivas através da criação da última fronteira agrícola do mundo (MATOPIBA). A fim de apresentar a importância dessa fronteira agrícola no Brasil, construiu-se e analisou-se uma matriz de Insumo-Produto Inter-Regional contendo fluxos comerciais entre as regiões do MATOPIBA, Resto no Norte (RN), Resto do Nordeste (RNDT) e Restante do Brasil (RB). Tal matriz apresentou desagregação para 14 setores nas quatro regiões. Concluiu-se que, os setores do MATOPIBA, apesar de apresentarem menores multiplicadores de produção em relação ao RB, possui as maiores taxas de transbordamento de investimentos para as demais regiões, apresentando assim, capacidade mais elevada em impulsionar a indústria nacional do que qualquer outra região do modelo. E o choque na demanda final, nos principais setores agrícolas da região do MATOPIBA, apresentou grande perspectiva de crescimento em todo modelo, tonando-se provavelmente, grande alvo para investimentos futuros.Abstract: Brazil is recognized worldwide for its excellent economic and productive performance in the agricultural sectors. With the growth in world demand for food, the country expanded its productive area through the creation of the last agricultural frontier in the world (MATOPIBA). In order to present the importance of this agricultural frontier in Brazil, an Inter-Regional Input-Output matrix was constructed and analyzed containing trade flows between the regions of MATOPIBA, Resto no Norte (RN), Rest of Northeast (RNDT) and Rest of Brazil (RB). It was concluded that the MATOPIBA sectors, despite having lower production multipliers in relation to the RB, have the highest investment spillover rates to the other regions, thus presenting a higher capacity to boost the national industry than any other region of the model. And the shock in the final demand, in the main agricultural sectors of the MATOPIBA region, presented great growth perspective in every model.

Poor water quality is associated with various water-related diseases, as well as economic losses due to medical expenses and reduced productive days due to illness. According to him, proper drinking water is not necessarily safe. Sanitation is a public health effort that focuses on monitoring various environmental factors in the provision of clean water, disposal of human waste (latrines), waste management and waste water disposal that affect health status. Stunting is a condition where the child's growth is disturbed so that the child becomes shorter than the normal height of the child's age obtained from height measurements. This study aims to determine the quality of refilled water or drinking water consumed by families from refill drinking water depots or drinking water cooked by stunting families in the working area of ​​Titi Papan Health Center. This type of research is descriptive research, with the research design is cross sectional. The result of this study is that sanitation and drinking water quality are significantly related to the incidence of stunting in the working area of ​​the Titi Papan Public Health Center, Medan Deli District. The most dominant variable related to the incidence of stunting at the Titi Papan Health Center, Medan Deli District, was sanitation with a PR value of 16,212 and p<0.05, this means that good sanitation has 16 times the chance of not having stunting compared to poor sanitation.

Reproducing Arctic springtime tropospheric ozone and mercury depletion events in an outdoor mesocosm sea ice facility
Authors: Gao Zhiyuan , Geilfus Nicolas-Xavier , Saiz-Lopez Alfonso , Wang Feiyue
Published: February 2022

Abstract. The episodic buildup of gas-phase reactive bromine
species over sea ice and snowpack in the springtime Arctic plays an
important role in boundary layer processes, causing annual concurrent
depletion of ozone and gaseous elemental mercury (GEM) during polar sunrise.
Extensive studies have shown that these phenomena, known as bromine
explosion events (BEEs), ozone depletion events (ODEs), and mercury depletion
events (MDEs) are all triggered by reactive bromine
species that are photochemically activated from bromide via multi-phase
reactions under freezing air temperatures. However, major knowledge gaps
exist in both fundamental cryo-photochemical processes causing these events
and meteorological conditions that may affect their timing and magnitude.
Here, we report an outdoor mesocosm study in which we successfully
reproduced ODEs and MDEs at the Sea-ice Environmental Research Facility
(SERF) in Winnipeg, Canada. By monitoring ozone and GEM concentrations
inside large acrylic tubes over bromide-enriched artificial seawater during
sea ice freeze-and-melt cycles, we observed mid-day photochemical ozone and
GEM loss in winter in the in-tube boundary layer air immediately above the
sea ice surface in a pattern that is characteristic of BEE-induced ODEs and
MDEs in the Arctic. The importance of UV radiation and the presence of a
condensed phase (experimental sea ice or snow) in causing such reactions were
demonstrated by comparing ozone and GEM concentrations between the
UV-transmitting and UV-blocking acrylic tubes under different air
temperatures. The ability of reproducing BEE-induced photochemical phenomena
in a mesocosm in a non-polar region provides a new approach to
systematically studying the cryo-photochemical processes and meteorological
conditions leading to BEEs, ODEs, and MDEs in the Arctic, their role in
biogeochemical cycles across the ocean–sea ice–atmosphere interface, and
their sensitivities to climate change.
Evolutionary multi-objective trajectory optimization for a redundant robot in Cartesian space considering obstacle avoidance
Authors: Liu Yong , Li Xiang , Jiang Peiyang , Du Zhe , Wu Zhe , Sun Boxi , Huang Xinyan
Published: February 2022

Abstract. A method of end-effector trajectory planning in Cartesian
space based on multi-objective optimization is proposed in this paper to
solve the collision problem during the motion of the redundant manipulator.
First, a cosine polynomial function is used to interpolate the trajectory of
the end effector, enabling it to reach the desired pose at a specific time.
Then, the joint trajectory of the manipulator is solved by inverse
kinematics, and the null space term is introduced as the joint limit
constraint in the inverse kinematics equation. During the operation of the
manipulator, the collision detection algorithm is employed to calculate the
distance between the obstacle and each arm in real time. Finally, a
multi-objective, multi-optimization model of trajectory that considers the
obstacle avoidance, joint velocity, joint jerk and energy consumption is
established and optimized with a multi-objective particle swarm optimization
algorithm. The simulation results demonstrate that the proposed method can
effectively accomplish the trajectory planning task and avoid obstacles; the
joint trajectories obtained are smooth and meet the limit constraints; the
joint jerk and energy consumption are well suppressed.
Analytical solution of the ray equations of Hamilton for Rossby waves on stationary shear flows
Authors: Gnevyshev Vladimir , Belonenko Tatyana
Published: February 2022

Abstract. The asymptotic behavior of Rossby waves in the ocean interacting with a shear stationary flow is considered. It is shown that there is a qualitative difference between the problems for the zonal and non-zonal background flow. Whereas only one critical layer arises for a zonal flow, then several critical layers can exist for a non-zonal flow. It is established that the integrated ray equations of Hamilton are equivalent to the asymptotic behavior of the Cauchy problem solution. Explicit analytical solutions are obtained for the tracks of Rossby waves as a function of time and initial parameters of the wave disturbance, as well as the magnitude of the shear and angle of inclination of the flow to the zonal direction. On the example of Rossby waves on a shear flow, the ray equations of Hamilton are analytically integrated. The obtained explicit expressions make it possible to calculate in real-time the Rossby wave tracks for any initial wave direction and any shear current inclination angle. It is shown qualitatively that these tracks for a non-zonal flow are strongly anisotropic.

Facing the challenges from different realities: e-learning approaches for Africa and Europe
Authors:   University of Coimbra, de Sousa Bruno , Gomes Dulce ,   University of Évora
Published: February 2022

Given that the UN’s Millennium Development Goals focus on primary education, Guy Pfefferman has observed how higher education was omitted within the African context. He also found that skills development for employment requires a radical change, advocating for eLearning as the only way to accomplish this in a meaningful and relevant way. In Africa we have the fastest growing population in the world with 40% under the age of 15 yet with one of the lowest higher education enrollments in the world, whereas in Europe we note an ageing corps of teachers, who despite being identified as having more experience, tend to suffer from technophobia. How to face the challenge of profiting from this experience and improve teaching practices when no more than 14% of the African population has access to internet? Simple ideas from a pilot study will be presented in order to overcome problems that may arise in less than perfect environments.

Published: February 2022

Through some research projects, studies have been carried out on the contents of essential university textbooks of Basic Statistics. Access to textbooks as “epistemological tutors of wise knowledge” is fundamental at the university level. At that level, instruction in statistics is primarily instrumental. An a priori analysis of the text allows us to identify and anticipate possible epistemological and didactic obstacles that present generalized difficulties and will generate frustrations and errors for some students. In this poster, we use the theoretical framework of Godino to present an analysis of text content that is incorporated into the integral study of the Institutional Meaning of Reference in the topic Confidence Intervals, in the Faculties of the National Universities in Argentina.

As part of the African Data Initiative, this poster focusses on the file menu of R-Instat and in particular the features relating to datasets. Statistical education is brought to life through the use of interesting and relevant data to engage learners in their tasks. The poster illustrates some key aspects of the import facilities and presents the richness of the inbuilt data library. It mentions some of the key ways in which these file features can and have been used for teaching and learning to change this situation. Particular attention will be drawn to the value of a true problem based approach where the students start with a problem and some data and are free to use an appropriate methods for the analysis. The key to this approach is to have data which is rich enough that a combination of approaches yields more insights than any single analysis. Transforming statistics education with R-Instat and projects could be a first step towards an African Data Revolution.

STAGES OF REFORMING THE INSTITUTION OF LOCAL SELFGOVERNMENT ON THE EXAMPLE OF THE REPUBLIC OF POLAND
Authors: D.O. Korotenko
Published: February 2022

The article examines the evolution of the institution of governance and
local self-government in the Republic of Poland. On the example of experience,
an analysis of effective mechanisms for implementing reforms in local selfgovernment of the Republic of Poland, and highlights the positive aspects of such
reforms. In this regard, the study of the institution of self-government in those
countries where the basic conditions of state-building are closest to the
Ukrainian ones are of special interest for domestic political science. It is the
Republic of Poland, where a multi-stage administrative and political reform has
been carried out, which contributes to the "new birth" and further reform of the
institution of local self-government.
Formulation of the problem. The idea of self-government in Poland is not
to manage local affairs in general and to represent the interests of the state, but
to represent the interests of a society that chooses its own government. At the
same time, local governments operate under the supervision of state bodies that
monitor the implementation of laws. Structurally, the system of local selfgovernment in Poland is three-tiered, namely: voivodship, county, gmina. It is the
study of foreign experience of close countries that have shown effective policies in
local government reform, and analysis to use the most effective experience for use
in modern Ukraine.
George Meniuc vs Tatiana Găluşcă: regăsirea spirituală prin folclor
Authors: Butnaru Tatiana
Published: February 2022

În articolul de faţă este dezvăluită colaborarea lui G. Meniuc cu Tatiana Găluşcă pe tărâmul cuvântului artistic, ceea ce l-a determinat să pătrundă mai temeinic în universul spiritualităţii populare, să ajungă la „o sinteză dintre geniul anonim şi valoarea individuală”, oferindu-i noi posibilităţi de resurecţie în modulaţiile codului estetic al poporului, a eticii sale multiseculare de viaţă. Odată ce „lumea asta e o transpunere în mit, vis de care are nevoie omul”, sugestie vehiculată de T. Găluşcă, G. Meniuc a reuşit să sintetizeze nişte imagini poetice, ce se redimensionează în conformitate cu straturile arhaice ale mentalităţii populare, acestea fiind dirijate de o logică mitică interioară, de resorturi şi stări sufleteşti deosebite. Reprezentările populare şi toposurile folclorice prefigurează în viziunea lui G. Meniuc un mediu tradiţional, omniprezent în mai multe versuri, determină aprofundarea anumitor aspecte ale realităţii artistice curente. Dialogul G. Meniuc vs T. Găluşcă, colaborarea lor sufletească pe tărâmul creaţiei artistice a devenit un frumos exemplu de comunicare spirituală, „o creangă de aur” menită să dăinuie dincolo de hotarele existenţei terestre.
Grigore Vieru: poezia pentru copii și poezia despre copii
Authors: Serdesniuc Cristian
Published: February 2022

Grigore Vieru debutează editorial cu o plachetă de versuri consacrate copilului și copilăriei. Prin poezia sa despre (și pentru) copii, poetul îl ajută pe cititorul mic să descopere orizonturile vieții și, totodată, să se descopere pe sine. Poetica viereană nu s-a despărțit de filonul copilăriei nici în abordarea temelor pentru maturi. Creația viereană se încadrează în cele două tipare ale literaturii: pe de o parte poezia pentru copii, prin care înțelegem o literatură pentru toată lumea, pe de altă parte, o poezie despre copii, care este inspirată din universul infantil al ludicului, mirajului și al afecțiunilor puerile. Dezmembrată concludent de conjuncturile regimului ideologic, impuse presant în literatura basarabeană sovietică, creația lui Grigore Vieru a râvnit insistent spre emancipare estetică. Anume poezia sa a marcat sugestiv revigorarea lirismului postbelic în literatura română din Basarabia.

Authors: Villa Romero Tomás , Ibáñez María Costanza , Marengo Hugo , Ibáñez Juan Carlos
Published: February 2022

Objetivo: Describir las fallas en diferentes sistemas de implantes al ser sometidos a fuerzas de torsión creciente, determinar el torque en el cual aparece un daño medible en el implante o alguno de sus componentes y especificar la falla más frecuente.

Materiales y métodos: Se realizó un estudio experimental in vitro. Se utilizaron 88 implantes agrupados según diseño y marca comercial (Federa, Rosterdent, Biomet 3i, Tree-Oss, B&W, ML) en 11 grupos de 8 implantes cada uno. Éstos fueron inmovilizados en acrílico y fijados en una prensa. Se aplicó una fuerza de torsión creciente con torquímetro de precisión digital hasta la aparición de alguna falla en el implante o sus componentes. Se registró el torque en el que se produjo la falla. Se realizó estadística descriptiva para el análisis de datos.

Resultados: El 100% de los implantes o alguno de sus componentes mostraron una falla detectable al ser sometidos a fuerzas de torsión creciente (rango de torque: 83,5 Ncm –implante con conexión cono morse 8 grados– a 384 Ncm –implante de conexión interna sin montar–). El torque promedio más bajo en el que aparecieron los daños fue 103,75 (±8,08) Ncm para implantes de conexión interna tipo cono morse, mientras que el más alto fue 279,87 (±89,73) Ncm para implantes de conexión interna sin montar. La falla más frecuente (28,4%) fue la fractura del tornillo del portaimplante y falseo del hexágono externo simultáneamente.

Conclusión: Las fallas detectables a fuerzas de torsión creciente ocurrieron entre 83,5 Ncm y 384 Ncm. La falla reiterada fue la fractura del tornillo del portaimplante y falseo del hexágono simultáneamente.

Palabras clave: daños mecánicos, fractura por sobrecarga, implantes dentales, resistencia mecánica, torque de inserción.

Published: February 2022

The single tax system reduces transportation time. But, the services of external consultants are used for various tax matters. The country’s taxation system has improved with the help of GST and the government should take more efforts to training and educating public. Due to frequent change in GST law, companies need to change their accounting system. The technical cost and legal cost in GST are very high and not satisfied with available required services of GST. So, transition to GST is very difficult. Some common problems faced by business are increased overhead expense, supply chain structure, excessive compliances and filling, delays in refund, GST filling, decline in business, refund mechanism and rise in input cost. The satisfaction level of GST after implication has not reached the expectation of all Governments, consumers & business. The urgent requirements for improvement in the nation’s interest include rationalizing GST rates, removing excess processes, creating efficiencies and removing debatable aspects. The present study analyzes the awareness and overview of GST in the study area. Key Words: Tax, GST, Revenue, Difficulties, Awareness, Overview, India.
