Annotation:
Područje Općine Vinica karakterizira bogata povijest s mnoštvom očuvane kulturne i prirodne baštine, a cilj ovog rada je predstaviti ove bogate kulturne slojeve kao i sudjelovanje Općine Vinica u projektu „Ruralna detoksikacija upoznavanjem bogatstva kulturne baštine DETOX SLO-HR 98“ koji se provodi u okviru programa prekogranične suradnje INTERREG V-A Slovenija - Hrvatska 2014-2020. U srednjovjekovnom razdoblju Vinica je bila važno trgovište s utvrdom castrum Vinica koja se spominje u 14. stoljeću i crkvom svetog Marka. Na području Općine Vinica u kasnijim je razdobljima izgrađeno nekoliko dvoraca, kurija te drugih građevina svjetovnog karaktera. Među njima se ističu ostatci dvorca Opeka, oko kojeg nastaje i vrijedan perivoj danas poznat kao arboretum Opeka. Značajne građevine su: kurija Patačić, kurija Mattačić-Dolansky, kurija Köröskeny-Rupčić te dvorac Bajnski Dvori s perivojem i kapelicom. Posebno je vrijedan kameni spomenik „Pranger“ nekadašnja mjera za žito i sramotni kamen, jedinstveni takav primjer očuvan na području sjeverozapadne Hrvatske. Od očuvane baštine viničkog kraja valja spomenuti barokni pil sv. Benedikta te barokni zdenac s kipom sv. Ivana Nepomuka. Tradicijska graditeljska baština na području Općine Vinica obilježena je očuvanim stambenim i gospodarskim građevinama koje su građene od kamena vinicita. Kamen vinicit vadio se u prošlosti, a također se vadi još i danas u kamenolomu Marčan na području Općine Vinica. Većina stambenih i gospodarskih građevina ovoga kraja građena je upravo od kamena vinicita. U sklopu INTERREG Programa DETOX SLO-HR 98 kao jedan od partnera sudjelovala je Općina Vinica. Na području Općine Vinica kroz ovaj je program obnovljena i uređena tradicijska vinička kuća građena od kamena vinicita, izrađena je replika nekadašnjeg viničkog sramotnog stupa i kamene mjere tzv. Prangera te je obnovljen barokni kip sv. Ivana Nepomuka.

Annotation:
Each year, more than half a million women are diagnosed with cervical cancer, resulting in about 300,000 deaths a year. In Macedonia cervical cancer is second most common according to the prevalence of malignant neoplasms in women. The most common and most studied cause is Human Papillomavirus (HPV). For the research were used statistical materials obtained from Center for Public Health – Kocani and State Statistical Office of R. Northern Macedonia. For the collected data from the organized screening on the territory of Kocani, Vinica, Berovo, Pehchevo and Delchevo for the period 2016-2020, as well as reported outpatient polyclinic morbidity for the same territory in a period of 10 years, ie from 2011 – 2020, was used statistical method. Screening with Pap smear is the best method to decrease the number of cervical cancer diseased and decrease mortality. Preliminary results from new immunotherapy approaches show promising results for overall survival. The main purpose of this research is to point out the importance of regular examinations and screening for early detection of cervical changes, prevention of invasive forms of cancer, and timely treatment.

Annotation:
In 2000, chlorotic leaves with inconspicuous leaf spots were observed on several Vinca major L. and V. minor L. plants in a 0.8-ha area in Woodside, CA. In August 2001, 80 to 90% of the plants were symptomatic. Uredinia measuring 2 to 3 × 1 mm were present on the lower surface of leaves. Urediniospores were ellipsoidal to oblong, 27 to 36 × 17 to 27 μm, with cinnamon-brown walls 1 to 2 μm thick, echinulate, and with three or four equatorial or slightly supraequatorial germ pores. Telia were produced in the uredinia. Teliospores were 1-septate, ellipsoidal to clavate, slightly constricted at the septum, and 34 to 45 × 19 to 30 μm. Teliospore walls were chestnut brown, 1.5 to 2.5 μm thick, and verrucose, with the verrucae sometimes in longitudinal lines. One germ pore covered by a hyaline papilla was present in each cell, at the apex in the upper cell and adjacent to the short, hyaline pedicel in the lower cell. The rust was identified as Puccinia vincae Berk. (1). P. vincae is widespread in Europe on Vinca species and is common on V. major in the eastern United States, Washington, and Idaho (2). To our knowledge, this is the first report of P. vincae on V. major in California (vouchers BPI 841363, 841364) and on V. minor in the United States (voucher BPI 841365). References: (1) J. C.

Les alcaloïdes de Vinca sont des molécules extraites de la pervenche de Madagascar et connues depuis les années 50 pour leur activité antitumorale. Il existe aujourd’hui quatre substances utilisées en chimiothérapie anticancéreuse dont deux sont d’origine hémisynthétique : la vinorelbine (Navelbine®) et la vindésine. La Navelbine® est aujourd’hui obtenue industriellement par le couplage de deux sous-unités ((+)-catharanthine et (-)-vindoline) extraites des feuilles de la pervenche de Madagascar. Dans la perspective d’une synthèse totale de la Navelbine®, nous nous sommes intéressés à la synthèse de la (+)-catharanthine. La synthèse formelle de la (+)-catharanthine a été réalisée en 19 étapes avec un rendement global de 1% et un excès énantiomérique supérieur à 99%. La vinflunine (Javlor®) est la dernière génération de molécule antitumorale dérivée des alcaloïdes de Vinca. Ses performances thérapeutiques sont supérieures à celles de la Navelbine® et la molécule est aujourd’hui produite industriellement par couplage de la catharanthine et de la vindoline puis fluoration en milieu superacide. La vinflunine se différencie principalement de la Navelbine® par la présence d’un groupement gem-difluoré dans son fragment nord. Nous nous sommes intéressés à la synthèse de dérivés fluorés de la catharanthine (précurseur du fragment nord) afin de développer une stratégie alternative à la synthèse de la vinflunine. Une isomérisation de l’insaturation C15-C20 de la catharanthine suivie de son oxydation nous a permis d’accéder via une étape de fluoration nucléophile à des dérivés mono et difluorés inédits de la catharanthine<br>Vinca alkaloïds are extracted from the leaves of Madagascan Periwinkle ant they are known since 1950 as powerful anticancer agents. Four drugs are currently administrated in cancer chemotherapy. Two of them are from semi-synthetic origin: vinorelbine (Navelbine®) and vindésine. Navelbine® is nowaday produced at an industrial scale through the coupling of two sub-units ((+)-catharanthine and (-)-vindoline) extracted from the leaves of Madagascan Periwinkle. We designed an enantioslective strategy directed toward the synthesis of (+)-catharanthine which is one of the two building block of Navelbine®. Formal synthesis of (+)-catharanthine was performed in 19 steps with an overall yield of 1% and an enantiomeric excess higher than 99%. Vinflunine (Javlor®) is the latest anticancer agent derived from Vinca alkaloïds. It turned out to be a more potent drug than Navelbine®. It is currently produced at an industrial scale through the coupling of catharanthine and vindoline followed by a fluoration step in superacidic conditions. Vinflunine can be distinguished from Navelbine® mostly by the two fluor atoms in its northern sub-unit. We designed a strategy for the synthesis of fluorous derivatives of catharanthine (northern subunit precursor) directed toward an alternative synthesis of vinflunine. Migration of the C15-C20 double bond of catharanthine followed by its oxidation allowed us to synthetize via a nucleophilic fluoration step new mono- and difluoro derivatives of catharanthine

Dentre as aplicações do PVC estão produtos médicohospitalares, os quais necessitam passar por processos de esterilização por radiação gama. Neste trabalho foi realizado um estudo sobre a estabilidade, frente à radiação gama, do PVC aditivado e também sobre a flexibilidade e estabilidade do PVC modificado quimicamente. O PVC foi modificado quimicamente pela substituição de átomos de cloro por grupos alquila e benzila através de reações com reagentes de Grignard; pelo grupo hidroxibenzila através da reação de Barbier em meio aquoso; e por mono éteres de dietileno glicol, através da reação com os reagentes organolítio. O polímero também foi modificado por reação de redução com zinco. Amostras de filmes do PVC aditivado foram expostas à radiação gama e seus parâmetros viscosimétricos, propriedades mecânicas e espectros na região do ultravioletavisível foram analisados para avaliar o efeito da radiação no polímero. Os sistemas poliméricos analisados foram o PVC/plastificante, em que os plastificantes utilizados foram: DOP-(di-2-etilhexil ftalato); DIBP-(di-iso-butil ftalato); TOTM-(trioctil trimelitato); Viernol-(plastificante polimérico), e o sistema PVC/DOP estabilizado com o tinuvin P. Observou-se que a exposição dos filmes PVC/plastificante à radiação gama provoca a degradação do polímero por cisão de cadeia, a diminuição das suas propriedades mecânicas (resistência à tração e percentual de alongamento) e o aumento da absorção a 400nm que caracteriza a degradação evidenciada pelo amarelamento do filme. Dos sistemas PVC/plastificante estudados o PVC/DOP foi o que apresentou maior degradação por cisão de cadeia. A adição do estabilizante tinuvin P ao sistema PVC/DOP diminuiu a degradação por cisão de cadeia, bem como minimizou a redução dos valores das propriedades mecânicas dos filmes submetidos à radiação gama. Os PVCs modificados quimicamente apresentaram, de uma forma geral, maior estabilidade à radiação gama que o PVC puro, com exceção dos PVCs modificados com os mono éteres de dietileno glicol. Os PVCs modificados com a substituição do anel aromático na cadeia do polímero foram os que apresentaram maior estabilidade frente a todas as doses de radiação aplicadas. Os PVCs modificados quimicamente apresentaram temperaturas de transição vítrea mais baixas que o PVC. Desta forma, a substituição de grupos diversos na cadeia do PVC aumentou a sua flexibilidade

Annotation:
La Cathepsine D est une protéase sécrétée dans l’environnement péritumoral des cancers du sein, qui pourrait activer sélectivement des prodrogues d’agents anticancéreux. Après une présentation des médicaments antitumoraux utilisés en clinique, des nouvelles approches chimiothérapeutiques et des prodrogues de cytotoxiques visant à améliorer la sélectivité, la synthèse et les études biologiques préliminaires de prodrogues de S12363, un vinca-alcaloïde développé par Servier, ont été exposées. Au cours de travaux antérieurs, des prodrogues composées d’un peptide substrat de Cathepsine D et de S12363 avaient été étudiées. Mais les fragments libérés après digestion s’étaient révélés inactifs, probablement à cause du fragment peptidique lié au médicament qui empêchait son entrée dans la cellule. Dans le but de contourner ce problème, un peptide vecteur a été intercalé entre le peptide substrat et le médicament, pour améliorer la pénétration du fragment. Mais cette approche n’a pas permis de retrouver l’activité du médicament, le problème semblant provenir d’une distribution cellulaire inadéquate ne lui permettant pas d’atteindre sa cible. Dans une seconde approche, le peptide substrat a été modifié pour qu’après digestion par la Cathepsine D, les acides aminés restants soient éliminés rapidement par formation de dicétopipérazine pour libérer S12363. Des prodrogues activées par la PSA ont également été développées. Ces dernières ont donné des résultats très prometteurs. En effet, les fragments libérés après digestion ont montré sur culture cellulaire une activité cytotoxique proche de celle du médicament. Des études in vivo sont donc envisagées. Des résultats moins favorables ont été obtenus avec les prodrogues de Cathepsine D, probablement à cause d’une libération plus lente du médicament. Le peptide substrat doit donc être optimisé. L’insertion d’un lien autoimmolable entre le peptide substrat et S12363 est envisagé pour éloigner le site de coupure de la protéase et libérer après digestion un composé dipeptidique<br>Cathepsin D is a protease secreted in the peritumoral environment of some breast cancers, which might activate selectively anti-cancer prodrugs. After the presentation of antitumoral drugs used in clinic, of new chemotherapeutic approaches and of cytotoxic’s prodrugs aimed at improving the selectivity, the synthesis and preliminary biological characterization of prodrugs of S12363, a vinca-alkaloïd developped by Servier, have been exposed. During previous studies, prodrugs composed of a Cathepsin D peptide substrate and S12363 have been studied. However the compounds released after digestion were shown inactives, probably because of the peptidic fragment linked to the drug, which would prevent its entrance inside the cell. In order to circumvent this problem, a cell-penetrating peptide was inserted between the peptide substrate and the drug, to improve fragment transduction. However this approach didn’t allow to recover drug activity. The problem seems to come from an inadequate cellular delivery, which prevented it to reach its target. In a second approach, the peptide substrate has been modified so that the remaining aminoacids after Cathepsin D digestion would be fastly eliminated by diketopiperazine formation to free S12363. Prodrugs activated by PSA have also been developped. They have given very promising results. Indeed, the compounds released after digestion have shown cytotoxic activity on cell culture close to that of the drug. In vivo studies are now considered. Less favourable results have been obtained with the Cathepsin D prodrugs, probably because of a slower drug release. The peptide substrate has so to be optimised. The insertion of a self-immolative linker between the peptide substrate and S12363 is considered, in order to take away the substrate scissile bond from the drug and to release a dipeptide compound after digestion

The planning office in Stockholm is currently working on a new mixed-use master plan for the rundown industrial site in Vinsta, Stockholm. Looking at how similar developments are executed, there is reason to believe that a large part of the building stock will be demolished.  There are several arguments that can be made in resistance to such a course of action; sustainability, preservation and cultural values are keywords in the conservative approach to the redevelopment of Vinsta that this thesis explores.  The project includes an analysis of the site and its structures, a proposal for a new urban layout as well as designs for some of the housing blocks that are part of the new configuration.

Devido à importância industrial e tecnológica dos látices estabilizados com poli(álcool vinílico)/PVA e a dificuldade encontrada na etapa de polimerização em emulsão, na presença de monômeros hidrofóbicos e de PVA\'s com alto grau de hidrólise (>92%), a síntese de novos estabilizantes poliméricos derivados de PVA para utilização em reações de polimerização em emulsão e em miniemulsão se torna muito atraente e desafiadora. O objetivo principal deste trabalho foi sintetizar novos estabilizantes poliméricos do tipo poli(álcool vinílico-co-neodecanoato de vinila)/PVA-VV com alto grau de hidrólise e conseqüentemente com propriedades diferenciadas, para serem utilizados como estabilizantes nas reações de polimerização em emulsão e em miniemulsão do acetato de vinila (VAc) com o neo-nonanoato de vinila (VEOVA-9), visando a obtenção de adesivos com propriedades diferenciadas para colagem de madeiras. Os novos estabilizantes poliméricos foram obtidos em duas etapas: i) copolimerização em solução do VAc com o neo-decanoato de vinila (VEOVA-10); ii) hidrólise alcalina (NaOH/Metanol) do poli(acetato de vinila-coneodecanoato de vinila). As miniemulsões de VAc com VEOVA-9 com diferentes tipos de estabilizantes poliméricos foram preparadas em um homogeneizador de alta pressão do tipo \"Manton Gaulin\". Foi estudado o efeito dos estabilizantes poliméricos (PVA e PVA-VV) na etapa de emulsificação (diâmetro médio das gotas, polidispersão, estabilidade das miniemulsões) e na copolimerização em emulsão e em miniemulsão do VAc com o VEOVA-9, em processo batelada. O efeito do tipo de iniciador (persulfato de amônio/APS e hidroperóxido de tércio butila/TBHP e peróxido benzoato de tércio butila/TBPB, juntamente com o formaldeído sulfoxilato de sódio/SFS) na cinética da polimerização em miniemulsão do VAc com o VEOVA-9 foi estudado em processo semi-contínuo. A distribuição dos estabilizantes poliméricos (PVA e PVA-VV) entre a fase aquosa e a superfície das partículas de polímero (adsorvido/enxertado) foi determinada e correlacionada com a viscosidade e a estabilidade coloidal dos látices. Látices na condição ideal de cópia (1:1) das gotas de monômero para as partículas de polímero foram obtidos via polimerização em miniemulsão, apresentando propriedades diferenciadas, tais como, menores valores de viscosidade, menor concentração de coágulos e maior estabilidade de estocagem, em comparação com os látices obtidos em emulsão.<br>Due to the technological and industrial importance of latexes stabilized with poly(vinyl alcohol)/PVA and the difficulties related to the emulsion polymerization of hydrophobic monomers and the use of PVA having a high degree of hydrolysis (> 92%), the synthesis of new PVA based polymeric stabilizers for use in emulsion and miniemulsion polymerizations becomes very attractive and challenging. The aim of this work was to synthesize a new class of polymeric stabilizer, poly(vinyl alcohol-co-vinyl neo-decanoate)/PVA-VV, with a high degree of hydrolysis and differentiated properties to be used as stabilizers in the emulsion and miniemulsion copolymerization of vinyl acetate (VAc) with vinyl neo-nonanoate (VEOVA-9), that can be used as adhesive for wood bonding. New PVA based polymeric stabilizers with high degree of hydrolysis (94 - 98%) were synthesized in two steps: i) solution copolymerization of vinyl acetate (VAc) with vinyl neo-decanoate (VEOVA-10) and ii) alkaline hydrolysis (NaOH/Methanol) of poly(vinyl acetate-co-vinyl neodecanoate). Miniemulsions of VAc/VEOVA-9 were prepared using the different polymeric stabilizers in a \"Manton Gaulin\" high pressure homogenizer. The effect of different initiators (ammonium persulfate/APS or tert-butyl hydro peroxide/TBHP and tert-butyl peroxide benzoate/TBPB in the presence of sodium formaldehyde sulfoxylate/SFS) in the polymerization kinetic was evaluated. The effect of the type and concentration of polymeric stabilizer, in the emulsification step (average diameter of drops, stability of miniemulsions) as well in the polymerizations (rate of consumption of monomers, particle size and particles number) was investigated in this work. The partition of the polymeric stabilizers between the aqueous phase and the polymer particle surface (grafted/adsorbed) was determined and correlated with the viscosity and colloidal stability of latexes. Latexes with differentiated properties such as low-viscosity, lower grits content and improved storage stability, were obtained by miniemulsion polymerization with an ideal condition copy (1:1) of the monomer droplets to the polymer particles.

O descarte inadequado de embalagens poliméricas tem gerado uma grande preocupação mundial. O alto consumo, atrelado ao curto tempo de uso dessas embalagens tem ocasionado um grande passivo ambiental. Diferentemente dos usuais polímeros empregados para este propósito, o poli(ácido lático) ou PLA é de fonte renovável e pode ser degradado no meio ambiente por ação de microrganismos como bactérias e fungos. Possui grande potencial para produzir sustentavelmente novos tipos de embalagens que sejam ambientalmente amigáveis. No entanto, para isso é preciso modificar algumas propriedades mecânicas para satisfazer sua aplicação, como a ductilidade e tenacidade. Uma boa alternativa para superar essas limitações é misturá-lo mecanicamente a um segundo polímero, produzindo blendas com propriedades melhoradas. Neste trabalho foram preparadas blendas poliméricas entre o PLA e o copolímero aleatório poli[(etileno)-co-(acetato de vinila)] (EVA), com teores de acetado de vinila (VA) de 65% (EVA65) e 90% (EVA90). As blendas foram preparadas por extrusão em dupla rosca co-rotacional interpenetrante. A morfologia e miscibilidade das blendas PLA/EVA foram estudadas por microscopia eletrônica de varredura (MEV), calorimetria exploratória diferencial (DSC) e análise termodinâmico-mecânica (DMTA). As propriedades mecânicas foram avaliadas por ensaios de tração, flexão em três pontos e resistência ao impacto Izod com entalhe. A influência do teor de VA na biodegradabilidade do PLA foi avaliada por perda de massa e por propriedades mecânicas em tração dos corpos de prova que foram submetidos ao teste de biodegradação em solo e ficaram enterrados por 0, 30, 90, 120 e 150 dias. As curvas DSC e os resultados de DMA mostram que as blendas PLA/EVA90 apresentam uma única temperatura de transição vítrea (Tg), sendo, portanto, miscíveis. Entretanto, as blendas PLA/EVA65 apresentam duas Tg e nítida separação de fases comprovando que são imiscíveis em todas as frações testadas. Mudanças como deslocamento da temperatura de cristalização do PLA são influenciados pelo aumento do teor de EVA nas blendas. Todas as blendas apresentam melhora nos resultados de flexibilidade e deformação na ruptura, destaque para amostra contendo 20% de EVA65 onde a deformação na ruptura foi 350% maior que o PLA puro. A resistência ao impacto da blenda contendo 30% de EVA65 representou um aumento na tenacidade aproximadamente 2400% em relação ao valor obtido pelo PLA puro. A taxa de biodegradação do PLA foi reduzida com o aumento do teor de EVA nas blendas. Blendas com EVA90 obtiveram maiores perdas de massa que as equivalentes contendo EVA65, revelando também a influência da miscibilidade na taxa de biodegradação do PLA. No entanto, ao final de 180 dias todos os corpos de provas sofreram variação negativa da massa, ou seja, foram biodegradados no solo.<br>The inadequate disposal of packaging materials has led to a major worldwide concern. The high consumption, together with the short usage time of packaging materials, has created a serious environmental issue. Unlike conventional polymers, poly(lactic acid) or PLA comes from a renewable source and can be degraded by microorganisms (e.g., bacteria and fungi) in the environment. PLA has a great potential for the sustainable development of environmentally friendly materials intended for packaging applications. To do so, however, some of its mechanical properties (e.g., ductility and toughness) must be modified to meet the technical requirement for such applications. A feasible alternative of overcoming these limitations is mechanically blending PLA with a second polymer, producing blends featuring improved properties. In this study, we prepared polymer blends by mixing PLA and the random copolymer poly[(ethylene)-co-(vinyl acetate)] (EVA) comprising vinyl acetate (VA) contents of 65% (EVA65) and 90% (EVA90). The blends were prepared through interpenetrating co-rotating twin screw extrusion. PLA/EVA blend morphology and miscibility were investigated through scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and dynamic thermomechanical analysis (DMTA). Mechanical properties were determined through tensile, three-point bending, and notched Izod impact strength tests. The influence of VA content on PLA biodegradability was assessed by weight loss measurements as well as tensile tests in specimens submitted to biodegradation in soil, wherein they remained covered for 0, 30, 90, 120, and 150 days. DSC curves and DMTA data showed that the PLA/EVA90 blends presented a single glass transition temperature (Tg), indicating miscibility. On the other hand, the PLA/EVA65 blends presented two Tg as well as marked phase separation, corroborating the immiscibility of all tested fractions. Shifts on the crystallization temperature of PLA are influenced by increased EVA contents in the blends. All blends showed improved flexibility and deformation at break, particularly that comprising 20% EVA65, which presented an elongation at break 350% higher than pristine PLA. The impact strength of the blend comprising 30% EVA65 evidenced a ca. 2400% increase in toughness in comparison with pure PLA. PLA biodegradation rate was reduced by increased EVA contents. EVA90-containing blends displayed greater weight losses than their EVA65-containing counterparts, also revealing the influence of miscibility on PLA biodegradation rate. Nevertheless, after 180 days, all specimens presented weight loss, that is, were biodegraded in soil.

Apesar de ainda enfrentar grandes desafios, a educação pública no Brasil vinha apresentando uma trajetória favorável na última década: entre 2007 e 2018, a lacuna socioeconômica da taxa de abandono no ensino médio sofreu uma redução de 62%. No entanto, com a pandemia da COVID-19, escolas fecharam e a economia desandou. O Brasil está entre os países com o período mais longo de escolas fechadas e é o sistema educacional com o maior número de estudantes impactados pela ausencia das aulas presenciais. A transição para o ensino remoto obrigou governos locais e famílias a se adaptarem ao novo contexto, mas até maio de 2020, 40% dos municípios ainda no possuíam sequer um plano de ensino remoto. Além disso, dados de conectividade da Anatel mostram que o número de conexões móveis per capita é significativamente menor em municípios com IDH mais baixo. O presente relatório discute os resultados de pesquisas levantadas no Brasil ao longo de 2020 e evidencias empíricas na literatura nacional e internacional sobre os possíveis efeito da pandemia na educação do país. As evidências sugerem que tanto a ausencia de aulas presenciais como a redução na renda das famílias causaram danos sem precedentes nos indicadores de aprendizagem e nas taxas de abandono e amplifiquem as desigualdades socioeconômicas educacionais no país. Diante disso, discute-se algumas recomendações de políticas que podem ajudar a mitigar o impacto da pandemia nos resultados educacionais no Brasil.

Lincoln Boyhood National Memorial celebrates the lives of the Lincoln family including the final resting place of Abraham’s mother, Nancy Hanks Lincoln. Lincoln’s childhood in Indiana was a formative time in the life our 16th president. When the Lincoln family arrived in Indiana, the property was covered in the oak-hickory forest type. They cleared land to create their homestead and farm. Later, designers of the memorial felt that it was important to restore woodlands to the site. The woodlands would help visitors visualize the challenges the Lincoln family faced in establishing and maintaining their homestead. Some stands of woodland may have remained, but significant restoration efforts included extensive tree planting. The Heartland Inventory and Monitoring Network began monitoring the woodland in 2011 with repeat visits every four years. These monitoring efforts provide a window into the composition and structure of the wood-lands. We measure both overstory trees and the ground flora within four permanently located plots. At these permanent plots, we record each species, foliar cover estimates of ground flora, diameter at breast height of midstory and overstory trees, and tree regeneration frequency (tree seedlings and saplings). The forest species composition was relatively consistent over the three monitoring events. Climatic conditions measured by the Palmer Drought Severity Index indicated mild to wet conditions over the monitoring record. Canopy closure continued to indicate a forest structure with a closed canopy. Large trees (&gt;45 cm DBH) comprised the greatest amount of tree basal area. Sugar maple was observed to have the greatest basal area and density of the 23 tree species observed. The oaks characteristic of the early woodlands were present, but less dominant. Although one hickory species was present, it was in very low abundance. Of the 17 tree species recorded in the regeneration layer, three species were most abundant through time: sugar maple (Acer saccharum), red bud (Cercis canadensis), and ash (Fraxinus sp.). Ash recruitment seemed to increase over prior years and maple saplings transitioned to larger size classes. Ground flora diversity was similar through time, but alpha and gamma diversity were slightly greater in 2019. Percent cover by plant guild varied through time with native woody plants and forbs having the greatest abundance. Nonnative plants were also an important part of the ground flora composition. Common periwinkle (Vinca minor) and Japanese honeysuckle (Lonicera japonica) continued to be the most abundant nonnative species, but these two species were less abundant in 2019 than 2011. Unvegetated ground cover was high (mean = 95%) and increased by 17% since 2011. Bare ground increased from less than 1% in 2011 to 9% in 2019, but other ground cover elements were similar to prior years. In 2019, we quantified observer error by double sampling two plots within three of the monitoring sites. We found total pseudoturnover to be about 29% (i.e., 29% of the species records differed between observers due to observer error). This 29% pseudoturnover rate was almost 50% greater than our goal of 20% pseudoturnover. The majority of the error was attributed to observers overlooking species. Plot frame relocation error likely contributed as well but we were unable to separate it from overlooking error with our design.
