Published: February 2022

The concentration of radioactive isotopes in honey is an important bioindicator of environmental contamination. For that purpose, a total of 66 samples of different types of honey (acacia, meadow, linden, sunflower, flower, forest, oilseed rape, chestnut) were examined. The samples were collected during 2020 and 2021 at different localities in the Republic of Serbia (Vojvodina, Central Serbia, Kosovo). Gamma spectrometric analysis was used to determine natural radionuclides 40K, 232Th, 226Ra, 238U, 235U and 22Na and anthropogenic radionuclide 137Cs. The obtained results indicate that the predominant radionuclide in all the analyzed honey samples is natural K-40, whose average activity was 74 Bq / kg. The activity of other tested radionuclides ranged as follows: Th-232: <1-2.0; Ra-226: 1.9-15.6; U-238: <1-31.4; U-235: <0.2-1.61 and Na-22: <0.2-2.4 Bq / kg. The activity of the artificial radionuclide Cs-137 was measured in 53% of the tested samples from the territory of Kosovo with the maximum value of 3.63 Bq / kg. Regarding the determined level of radioactive residues, it can be concluded that the honey produced in the Republic of Serbia is healthy and environmentally safe food.

Investment is the process of saving money and putting it somewhere in the hope that it will increase in value. Many people are not familiar with the capital market, and many people who don't know much about it are more likely to invest in it and fall victim to fraud. In order to reduce fraud and feel safe when investing, the Indonesian people need to learn investment knowledge. The growth of Islamic banks has helped Islamic law develop as a part of the financial market. Although Indonesia is currently being hit by the Covid-19 pandemic, it is undeniable that the growth of the Islamic capital market in Indonesia has increased quite significantly. The Millennial generation is now looking for and trying to start investing. The millennial generation has the highest rate of unemployment of any generation in history.

Community Tree Programs In Illinois, U.S.: A Statewide Survey And Assessment
Authors: Schroeder Herbert W. , Green Thomas L. , Howe Timothy J. 
Published: February 2022

AbstractThis article reports the combined results of two surveys of Illinois, U.S., communities about the status and needs of their community tree programs. The surveys were intended primarily to help state and federal agencies and private organizations to more effectively target the support they give to Illinois community tree programs. In 1995, we surveyed individuals responsible for tree care activities in small Illinois communities (population less than 25,000), and in 1999 we extended the survey to communities with populations of 25,000 or greater. Local municipal officials, regardless of community size, have strong positive attitudes toward the value of trees to their communities. Communities vary, however, in their resources, problems, and needs relating to their public trees. In particular, small communities often lack key components of an effective tree program and trained personnel for carrying out these programs. In providing assistance for community tree programs, state, federal, and private organizations should keep in mind the distinct needs and opportunities of communities of different sizes.

Published: February 2022

AbstractThe objective of this research was to compare red maple(Acer rubrumL.) root and canopy growth 5 years after landscape planting from seven different container designs maintained under two irrigation regimes. Trees planted from low-profile air root-pruning containers had larger trunks 5 years after landscape installation than those planted from regular air root-pruning containers, wood boxes with cupric hydroxide coating, or standard black plastic containers with cupric hydroxide coating. Despite significant differences in root weight and amount of deflected roots among container types when trees were planted in the landscape, root number, root depth, and radial root distribution around the trunk were identical 5 years after planting from all container types. However, frequency of irrigation in the first 24 weeks following planting had a significant effect on root system structure even 5 years later. Frequent irrigation resulted in larger trunks, more roots, greater root cross-sectional area, and a more uniform radial root distribution. The increase in root growth on frequently irrigated trees occurred exclusively in the top 30.5 cm of soil. Codominant stems 4 years after planting were equally common, regardless of production method and irrigation treatment. With the exception of the low-profile air root-pruned container, the reduction in root defects on the outer surface of root balls grown in containers designed to reduce defects appeared to provide no measurable benefit to trees 5 months or 5 years after planting into the landscape. Irrigation management after planting had a more positive impact on landscape root growth and distribution than container type.
Evaluation of Extraction Force for Wooden Guy Anchors
Authors: Smiley E. Thomas , LeBrun Elden , Gilbert Elizabeth 
Published: February 2022

AbstractWooden stakes are used to anchor guy lines on many newly transplanted trees. It has been recommended that the angle of the stake be either in-line with the guy (45 degrees toward the tree) or at right angles to the guy (45 degrees from horizontal away from the tree). This trial was conducted to determine which, if either, of these directions will provide the maximum amount of resistance to extraction. Stakes were driven into the soil at two angles and vertically into the soil then were extracted using a measured force. There was no significant difference in force required to extract the stakes driven in-line with the guy or at a right angle to it. There was a significant difference (p <. 05) between angled stakes and those driven straight into the soil. The force required for extraction of the stake driven vertically was more than twice that of the angle-driven stakes. It was hypothesized that the differences in extraction force were due to soil disruption that occurs when driving stakes into the soil. For maximum strength, it is recommended that wooden stakes be driven vertically into the soil.
Eastern Hemlock Recovery From Hemlock Woolly Adelgid Damage Following Imidacloprid Therapy
Authors: Webb Ralph E. , Frank J. Ray , Raupp Michael J. 
Published: February 2022

AbstractHemlock woolly adelgid (Adelges tsugae) is a serious pest of hemlocks (Tsugaspp.) in the eastern United States. A variety of insecticides are capable of controlling hemlock woolly adelgid. The use of a systemic insecticide, imidacloprid, has gained widespread acceptance and use in the plant care industry. While several studies demonstrate the efficacy of imidacloprid in reducing adelgid populations, none have examined how hemlocks recover following imidacloprid therapy. Using specimenTsuga canadensistrees in a residential landscape, we found that hemlocks recovered dramatically with new growth once the pressure of the adelgids was reduced following an application of imidacloprid. Most important, the response of trees to imidacloprid therapy differed in relation to their condition at the onset of the experiment. Trees with the healthiest, most foliated canopy improved the least following the reduction in adelgid populations. Trees with little new growth but no dieback recovered the quickest and most densely. Trees in the poorest condition at the onset recovered impressively but more slowly. Trees left untreated remained sparsely foliated, with dieback. These results confirm the value of imidacloprid therapy in improving the quality of hemlocks under attack by the hemlock woolly adelgid in urban forests.
Integrated Vegetation Management On an Electric Transmission Right-of-Way in Pennsylvania, U.S.
Authors: Yahner Richard H. , Hutnik Russell J. 
Published: February 2022

AbstractIntegrated vegetation management (IVM) has been used for the maintenance of vegetation along an electric utility transmission right-of-way (ROW) at the State Game Lands (SGL 33) Research and Demonstration Area, Centre County, Pennsylvania, U.S., since 1987. In addition, the wire–border zone method was implemented on the ROW in 1987. The wire–border zone method results in forb–grass–shrub cover types in wire zones and shrub cover types in border zones. The SGL 33 Research and Demonstration Area has been studied since 1953, which makes this 51-year-old project the longest continuous study documenting the effects of mechanical and herbicidal maintenance on flora and fauna along an electric transmission ROW. In this paper, our objective is to present target (undesirable) tree density and cover-type development in response to IVM prior to the most recent treatment (2000) and 2 to 3 years after treatment. Results were compared to those obtained from the late 1980s and 1990s. For all units combined (except handcut) in 1999, average target tree densities prior to treatment were 288 trees/ha (117 trees/ac) in wire zones and 759 trees/ha (307 trees/ac) in border zones. Excellent control of target tree density [62 to 124 trees/ha (25 to 50 trees/ac)] was noted in wire zones of mowing plus herbicide, stem–foliage spray, and foliage spray units; moderate control [371 to 680 trees/ha (150 to 275 trees/ac)] was observed in low-volume basal spray, high-volume basal spray units, and mowing units; and poor control (4,818 trees/ha [1,951 trees/ac]) was found in the handcut unit. In 2003, the density of target trees in all treatment units combined was 1,544 trees/ha (625 tree/ac) in wire zones and 1,594 trees/ha (645 trees/ac) in border zones. If the handcut unit was omitted from the calculations, then only 340 target trees/ha (138 trees/ac) in wire zones and 501 trees/ha (203 trees/ac) in border zones were present. IVM of a ROW is not a “tree-proof” but rather a “tree-resistant” means of reducing tree invasion. Competition with existing plants and wildlife predation on tree seeds on a ROW managed via the wire–border zone method minimized but did not eliminate tree invasion. Since 1987, IVM and the wire–border zone method of ROW maintenance has increased the time between treatment cycles, thereby reducing labor and chemical costs at the SGL 33 Research and Demonstration Area.
Relationship Among Tree Canopy Quantity, Community Demographics, and Tree City USA Program Participation in Maryland, U.S.
Authors: Galvin Michael F. , Bleil David 
Published: February 2022

AbstractThe Tree City USA (TCUSA) program is a national program in the United States that provides recognition to communities that meet certain standards, including having a tree ordinance and spending at least US$2.00 per capita on urban forestry. Census data for 2000 were combined with records on TCUSA program participation and tree canopy cover data for 74 communities in Maryland, U.S., to ascertain relationships among tree canopy quantity, community demographics, and Tree City USA program participation. Communities participating in TCUSA had widely varying demographics (2.2% to more than 97% nonwhite) but tended to have larger overall populations and larger nonwhite populations than did nonparticipating communities, with the percentage of nonwhite population slightly higher for nonparticipants. Multivariate statistical analysis showed that the most predictive variable related to the amount of canopy cover is the size of the city in hectares (acres). A combination of city population, hectares (acres) of tree cover, expenditures per capita on trees, and city size in hectares (acres) produced the greatest predictability in whether a city participates in the TCUSA program. The relationship between quantity of tree canopy and total population was stronger in participating than in nonparticipating communities. However, the relationship between land area and quantity of tree canopy was stronger for nonparticipants than for participants, and overall percentage of canopy cover as well as mean percentage of canopy cover were higher in nonparticipating communities. TCUSA participants in Maryland have similar land areas, similar ethnic demographics, higher populations, and canopy coverage more closely related to population than land area when compared to non-TCUSA communities and are most likely to be found in an urban/suburban context, while non-TCUSAs are more likely to be found in a rural (agricultural/forest) context.
Trees and Business District Preferences: A Case Study of Athens, Georgia, U.S.
Authors: Wolf Kathleen L. 
Published: February 2022

AbstractAs a National Main Street program participant, Athens, Georgia, U.S., has included streetscape tree plantings in economic development efforts. The Main Street program assists downtown merchant groups with physical improvements planning in order to create vital retail environments. If comprehensively managed, the urban forest can be a beneficial long-term improvement. Nonetheless, business people and merchants often have negative perceptions about trees (such as debris and reduced sign visibility) and may influence local policy and budget support for urban forest programs. This study utilized an on-site survey to elicit preference and perceptual response from visitors of the Athens central business district. The presence of a full-canopy forest was found to be associated with higher visual quality ratings of the retail district. District visitors also perceived the streetscape canopy to be an integral amenity of the city’s shopping environment. Quantitative and qualitative research outcomes are reported.
Anticorrosive Behaviors of Epoxy Coating Modified by Hydrophobic Nano-Silica and Graphene on Phosphatized Carbon Steel

Published: February 2022

Corrosion of carbon steel causes many losses, hazards, and contaminations to our daily life. In this article, epoxy synergistically added with hydrophobic nano-silica and graphene was prepared to provide corrosion protection for carbon steel. Graphene can act as filler to improve the corrosion resistance of epoxy, but the aggregation of graphene severely affects its application. Embedding hydrophobic nano-silica into graphene sheets contributes to the good dispersity of graphene in an epoxy matrix. Besides, SiO2 can also act as another filler to improve corrosion resistance. Hence, the synergistical addition of hydrophobic nano-silica and graphene into epoxy can provide better corrosion resistance for modified epoxy coating. A scanning electron microscope was used to investigate the microstructures of modified epoxy coating. Coating wettability was measured by a static contact angle measurement instrument. The anticorrosive behaviors of modified coatings were measured by an electrochemical workstation. The corrosion mechanism was analyzed by equivalent circuits simulation. According to the results, the modified coating with impedance of about 108 Ω·cm2 (10 mHz) at 100 d immersion still showed excellent anticorrosive performance. In general, epoxy doped with hydrophobic nano-silica and graphene displays better corrosion protection than epoxy without modification.

Abstract. Understanding the spatiotemporal dynamics of global
urbanization over a long time series is increasingly important for
sustainable development goals. The harmonized nighttime light
(NTL) time-series composites created by fusing multi-source NTL observations provide a long and
consistent record of the nightscape for characterizing and understanding global urban dynamics. In this study, we generated a global dataset of
annual urban extents (1992–2020) using consistent NTL observations and
analyzed the spatiotemporal patterns of global urban dynamics over nearly 30 years. The urbanized areas associated with locally high intensity human
activities were mapped from the global NTL time-series imagery using a new
stepwise-partitioning framework. This framework includes three components:
(1) clustering of NTL signals to generate potential urban clusters, (2) identification of optimal thresholds to delineate annual urban extents, and
(3) check of temporal consistency to correct pixel-level urban dynamics. We
found that the global urban land area percentage of the Earth's land surface
rose from 0.22 % to 0.69 % between 1992 and 2020. Urban
dynamics over the past 3 decades at the continent, country, and city
levels exhibit various spatiotemporal patterns. Our resulting global urban
extents (1992–2020) were evaluated using other urban remote sensing products
and socioeconomic data. The evaluations indicate that this dataset is
reliable for characterizing spatial extents associated with intensive human
settlement and high-intensity socioeconomic activities. The dataset of
global urban extents from this study can provide unique information to
capture the historical and future trajectories of urbanization and to
understand and tackle urbanization impacts on food security,
biodiversity, climate change, and public well-being and health. This dataset
