Tüketicilerin Geri Dönüştürülmüş Maddelerden Yapılmış Kıyafetleri Satın Alma İsteğini Etkileyen Faktörlerin İncelenmesi
Authors: Yemez İbrahim , Tuna Murat Fatih
Published: March 2022

Çevre bilincinin artmasıyla tüketicilerin doğayı daha fazla koruma bilincine sahip olması, mevcut kaynakların gereksiz yere kullanımını engellemeye ve yenilebilir enerji kaynaklarının kullanımının arttırılmasına yönelik çalışmalara imkân sağlamıştır. Geri dönüştürülmüş maddelerden yapılan ürünleri kullanmak da bu anlayışın bir tezahürüdür. Bu bağlamda bu çalışmada, tüketicilerin geri dönüştürülmüş maddelerden yapılmış kıyafetleri satın alma niyetleri üzerinde etkili olan faktörlerin ortaya konulması amaçlanmıştır. Bu amaçla 25 Ocak-3 Şubat 2021 tarihlerinde çevrimiçi olarak, 18 yaşından büyük toplam 462 kişiden veri toplanmıştır. Çalışmada ilk olarak Türkçeye çevrilen ölçeğin geçerliliği ve güvenirliği ortaya konulmuştur. Daha sonra PLS-SEM ile araştırma modeli Yol Analizine tabi tutulmuştur. Analiz sonucunda tüketicilerin geri dönüştürülmüş kıyafetleri satın alma niyetleri üzerinde çevresel kaygının, ödeme istekliliğinin ve algılanan değerin pozitif bir etkisinin olduğu ama kişisel normların ise bir etkisinin olmadığı görülmüştür. Ancak genel olarak bu dört faktöründe tüketicilerin geri dönüştürülmüş kıyafetleri satın alma niyetleri üzerinde yaklaşık %63 etkisi olduğu görülmüştür.

Nowa bilateralna umowa podatkowa Polski z Gruzją w świetle stanowiska Polski i Gruzji wobec Konwencji Wielostronnej oraz aktualizacji Konwencji Modelowej OECD i Konwencji Modelowej ONZ z 2017 roku
Authors: Kukulski Ziemowit
Published: March 2022

Artykuł dotyczy rozwiązań przyjętych w nowej bilateralnej umowie podatkowej, zawartej 7 lipca 2021 r. między Polską a Gruzją, która zastąpi umowę między tymi państwami z 5 listopada 1999 r. Zgodnie z wolą obu umawiających się stron nie została ona objęta postanowieniami Konwencji wielostronnej implementującej środki prawa traktatowego mające na celu zapobieganie erozji podstawy opodatkowania i przenoszeniu zysku. W związku z tym wprowadzenie do niej klauzul antyabuzywnych oraz sposobów usprawniających rozwiązywanie sporów musiało nastąpić w drodze dwustronnych negocjacji. Autor analizuje wpływ Konwencji wielostronnej, Konwencji Modelowej OECD i Konwencji Modelowej ONZ na kształt zaadaptowanych w niej rozwiązań oraz ich znaczenie dla przyszłości polskiej praktyki traktatowej.
Przemiany zespołu osadniczego Bełchatów-Rogowiec pod wpływem eksploatacji złóż węgla brunatnego
Authors: Gardjan Izabela , Szmytkie Robert
Published: March 2022

Głównym celem niniejszej pracy jest identyfikacja zmian sieci osadniczej w rejonie Bełchatowa, obejmująca zarówno zmiany, którym podlegało samo miasto, jak i przemiany w lokalnym układzie osadniczym. Przełomowym momentem w historii miasta i jego okolic było odkrycie dużych pokładów węgla brunatnego w sąsiedztwie wsi Piaski w gminie Kleszczów na przełomie lat 60. i 70. XX w., co przyczyniło się do ukształtowania zespołu osadniczego Bełchatów-Rogowiec. W toku prowadzonych badań zidentyfikowano cztery główne kierunki przekształceń sieci osadniczej: zmiany osadnicze związane z budową odkrywki i zwałowiska, rozwój miasta Bełchatów jako głównego ośrodka usługowo-mieszkaniowego, rozwój gminy wiejskiej Kleszczów jako głównego ośrodka pracy oraz procesy suburbanizacji w otoczeniu obszaru rdzeniowego. Analiza przekształceń społeczno-ekonomicznych w rejonie Bełchatowa umożliwiła określenie schematu rozwoju zespołu osadniczego.

Published: March 2022

Celem artykułu jest prezentacja targów gier komputerowych GameON zorganizowanych w Kielcach w 2019 r. Problem badawczy stanowiła ocena oddziaływania imprezy na rozwój produktu miejskiego Kielc oraz na promocję miasta. Opracowanie oparto na wynikach badań ankietowych wykonanych w grupie respondentów będących widzami imprezy. Zastosowano dobór dostępnościowy, dlatego rezultaty analizy nie mają charakteru reprezentatywnego. Za podbudowę teoretyczną posłużyła koncepcja event marketingu miast. Przeprowadzone badania wykazały, że zdaniem respondentów targi GameON 2019 to interesujące wydarzenie wzbogacające produkt miejski Kielc (głównie produkt turystyczny), wpływające pozytywnie na promocję miasta, a w konsekwencji na jego markę. Wykorzystana w artykule koncepcja obrazująca proces event marketingu miast znalazła swoje potwierdzenie w wybranym do badań studium przypadku.
Formy i rozmieszczenie wydarzeń z zakresu plenerowej rekreacji twórczej w Łodzi
Authors: Mroczek-Żulicka Aleksandra
Published: March 2022

Celem artykułu jest charakterystyka zjawiska plenerowej rekreacji twórczej oraz jej rozmieszczenia w przestrzeni rekreacyjnej Łodzi. Pojęcie rekreacji twórczej zostało na nowo zdefiniowane przez połączenie założeń geografii turyzmu i geografii rekreacji z psychopedagogicznymi teoriami dotyczącymi twórczości. Wykorzystując definicję operacyjną badanego zjawiska, przeprowadzono kwerendę zawężoną do analizy wydarzeń z zakresu rekreacji twórczej w plenerze Łodzi w 2019 r. Na jej podstawie dokonano analizy przestrzennej rozmieszczenia zjawiska, dzięki której dowiedziono, że badane wydarzenia najczęściej miały charakter aktywności kulturalno-rozrywkowej, odbywały się w porze letniej, zwykle były cykliczne, bezpłatne i organizowane na terenach zieleni i terenach postindustrialnych, znajdujących się przeważnie w centrum miasta. Wskazano także inne istotne czynniki lokalizacji tego typu wydarzeń. Charakterystyka zjawiska rekreacji twórczej i jej rozmieszczenia w plenerze wpisuje się w badania nad jakością organizacji miejskiej przestrzeni rekreacyjnej, która wpływa na wyższy standard życia mieszkańców. Przykład Łodzi, miasta wpisanego do Sieci Miast Kreatywnych UNESCO, pozwala na podjęcie dyskusji na temat znaczenia organizacji miejskiej przestrzeni rekreacyjnej dla rozwoju współczesnych miast.

Rendimiento intelectual de niños-infantes a adolescentes de clase socio-económica media y baja de Lima y de algunas provincias
Authors: Majluf Alegría
Published: March 2022

La recopilación y revisión de un conjunto de estudios comparativos referentes al rendimiento intelectual de niños peruanos (desde la infancia hasta la adolescencia) conducidos por diferentes investigadores, muchos de ellos no publicados, muestran que:Los niños de las zonas marginales o de los Pueblos Jóvenes de Lima y de algunas provincias rinden intelectualmente, tanto en pruebas psicométricas y Piagetianas, en forma disminuida y significativamente más baja que los niños de las clases más acomodadas.La disminución intelectual constatada en estos niños tiende a acentuarse aún más con la edad y en las zonas rurales más que en las urbanas.Los varones, en general, muestran un desempeño mejor que las mujeres, aún en la infancia.El desarrollo físico de los niños de la Clase socio-económica baja es, así mismo, poco satisfactorio. Las medidas antropométricas revelan un deficiente desarrollo físico.Los niños que viven en la altura son de menor peso y estatura que los niños que viven en baja altura o en la Costa.Los pre-escolares de las zonas pauperizadas muestran, en general, inmadurez para el aprendizaje y posteriormente retraso en la lectura y en el rendimiento escolar.En conclusión, la disminución generalizada en el rendimiento intelectual, físico y escolar de los niños de las zonas marginales, la que parece acentuarse aún más con la edad y en las zonas rurales, evidencia la necesidad de estudiar en forma más sistemática el perfil del niño peruano para poder obtener normas nacionales y regionales, las que permitirán una mejor planificación de los programas de intervención integral.

Authors: Singh K.N. , Khalkho D. , Singh R. , Tripathi M.P.
Published: March 2022

Background: Bundelkhand region is far behind in the availability of soil and water both natural resources due to erratic rainfall and hard rock terrains (Tyagi, 1997). Conservation of such type of natural resources for livelihood security with a strong commitment would be the foremost challenge of the 21st century. The home of over 15.62 million humans and 8.36 million livestock, suffers from water scarcity, natural resource degradation, low crop productivity (1-1.5 Mg/ha), low rainwater use efficiency (35-45%), poor soil fertility, frequent droughts, poor irrigation facilities, inadequate vegetation cover and frequent crop failure resulting in scarcity of food, fodder and fuel (Palsaniya et al. 2008). Under such circumstances, the goal of doubling farmer’s income by the year 2022 has been dubbed as impossible and unrealistic by some experts (Gulati and Saini, 2016). Hence, this study was conducted to assess the impact of agroforestry based crop production for provide an economic feasibility as well as perfect diet. Methods: The study was conducted at Garhkundar-Dabar (GKD) watershed located between 78° 52' 39" to 78° 54' 44" E longitude and 25° 26' 23" to 25° 28' 32" N latitude with an altitude varying from 208 to 285 m above mean sea level in Bundelkhand region of central India. The net return was calculated by subtracting the cost of cultivation incurred from sowing to harvesting, for each crop from the gross return and then benefit-cost ratio was estimated by dividing the net returns with cost of cultivation. Result: The study has revealed that after watershed interventions and agroforestry based Crop cultivation, the expenses on irrigation and labour will decrease, crop productivity will improve as well as benefit-cost ratio.
Bruchid Resistance in Pulses: A Review
Authors: Arulselvi S. , Dharani K. , Kamalnathu T. , Kishore S. , Tamilselvi C. , Chitra M. , Velayutham A.
Published: March 2022

The pulse crops are crucial for human nutrition not only because of their rich source of proteins but also for their dietary fibres, complex carbohydrates, resistant starch, vitamin complex and minerals. Pulse crops include mungbean, urdbean, redgram, bengalgram, adzuki bean and cowpea which are agriculturally and economically important crops in tropical and subtropical regions. Bruchid beetles, [Callosobruchus chinensis (L.)] and [C. maculatus (F.)] are the most serious insect pests of Vigna crops especially during storage. Infestation starts in the field and carried to storage godowns, where sometimes it causes total destruction of the seeds within six months. The damage is caused by the grubs, which feed on the entire grain contents leaving only the shell behind. The seeds thus loss its viability and they are rendered unfit for human consumption. Use of resistant cultivars is the best way to manage the bruchids. Hence, the resistant accessions can be effectively used as promising donors for developing bruchid resistant varieties which would ensure food security by reducing postharvest losses under storage conditions.
Amplified Fragment Length Polymorphism based Genetic Diversity of Tropical Legume: Lablab purpureus var. typicus
Authors: Singh Vishwajeet , Wahi Nitin , Garg Gunjan , Singh Anshu
Published: March 2022

Background: Lablab purpureus L. is a legume appropriate to grow in tropical environment as it is adaptable to a broad temperature spectrum, rainfall and altitudes. It develops well under humid and warm conditions at temperatures ranging between 18oC and 30oC. It is a drought hardy crop grown in humid and semi-arid regions. The species is propagated by seed and can be sown alone or intercropped; planted near hedges or near other less leafy plants to climb on. Lablab purpureus L. has a flowering response of short-day, with early and late flowering types. Some landraces flower after sowing as early as 55 days. It is predominantly self pollinated although some out crossing is known to occur. Methods: In this study, Lablab purpureus L. genetic diversity were analyzed utilizing AFLP markers on ten Indian Lablab purpureus L. accessions at Department of Botany, Bundelkhand University, Jhansi during 2019-20. Five primers set were used for checking the diversity in Lablab purpureus L. and the marker performance were measured by using 4 parameters i.e. PIC, Mean resolving Power, Resolving Power and MI. Result: A total of 52 bands were generated, of which 45 bands (88.46%) were polymorphic which varies from 6 (M-CAT/E-ACT ) to 13 (M-CAC/E-ACC, M-CAC/E-ACT) with mean of 9.00 bands per primer. The PIC value ranges between 0.55 and 0.76 with a mean value of 0.64. The average value of matrix index is 3.04. Higher the MI, better the marker is. The value of RP ranges between 2.60 and 7.80 with a mean value of 4.68. In the UPGMA dendrogram, the 10 accessions were separated into two main clusters with all the primers used. In this study, we have shown that molecular markers can be used successfully to understand the genetic structure of the accessions of Lablab purpureus L. and identified a series of sequence-specific markers that potentially could be used in Lablab purpureus L. genetic mapping analyses. Since Lablab purpureus L. has been considered as a promising crop because of its wide spectrum of adaptability to different ecological conditions than other legumes, participatory evaluation at an early breeding stage could shape the variety being developed to increase the productivity and other traits as well as for utilization as food.

Published: March 2022

Background: In conventional agriculture, expensive phosphatic fertilizers were applied in huge quantities to reduce phosphorus deficiency in mungbean. Disproportionate application of these chemical fertilizers over long periods has damaged the natural properties of soils by killing soil micro flora and fauna, leading to reduced agricultural production. Sustainable agriculture based on organics and biological fertilizers is an effective solution for overcoming these problems. Therefore, keeping the above information in view, the present study was undertaken to assess the effect of PROM and microbial inoculants on the growth and yield of mungbean. Methods: In this field-laboratory experiment which was conducted at agronomy farm of Sri Karan Narendra Agriculture University, Jobner, during Kharif season of 2019, 12 treatments involving control, PROM, PSB, VAM, Pseudomonas fluorescens (PF) and their respective combinations were included which was laid out in randomized block design with three replications. The collected samples were determined for growth and yield attributes in the field and laboratory. Result: The results showed that combined application of PROM+PSB+VAM+PF reported the maximum values of most of the growth and yield attributing characters i.e. plant height, number of branches/plant, dry matter accumulation, total and effective number of root nodules per plant, fresh and dry weight of nodules per plant, crop growth rate, chlorophyll content, number of pods/plant, number of seeds/pod, test weight, seed, straw and biological yield of mungbean as compared to other combinations and control, but it was at par with PROM+PSB+VAM.
Between the Material and the Social. Neighborhood Relations of Older People “Inside” the Infrastructure Deficit
Authors: Galkin Konstantin
Published: March 2022

. The article analyzes neighborhood relations in the villages of the Leningrad region. The material was interviews with older people about the peculiarities of rural everyday life and about neighborhood interactions in the context of the infrastructure deficit characteristic of the villages where the study was conducted. Based on the theoretical work of H. Plesner and A. Gelena, the author argues that neighborhood relations can be considered as an important social resource for the older, which is able to adjust and make more comfortable material resources in villages. The adaptability of material and social resources makes it possible to understand the specifics of the meanings of neighborhood relations that are formed in villages, and how aging can be represented based on the key and basic needs of older people. Empirical material was collected in two villages of the Leningrad region.
In the landscape caused by the infrastructure deficit, the usual neighborhood solidarity did not work, but such a landscape itself was part of a new solidarity associated with special interactions in which neighborhood relations create the tunability of material resources and are aimed at reciprocal exchange and neighborly assistance and minimizing the problems of infrastructure deficit.

Authors: Kim Ju-Sub
Published: March 2022

Purpose: This study aims to investigate the effects of noni oil on damaged hair.Methods: Three doses of noni oil, namely, 2, 4, and 6 g, were added to hair quality enhancers and applied to the hairs in a sample bleached at level eight. The sample was then compared with damaged hair. A color meter was used to measure the L* value to identify changes in hair brightness. In addition, tensile strength, absorbance using methylene blue, and glossiness were measured to verify improvement in damaged hair.Results: The mean L* value of the sample increased with increased oil content, which indicated a statistical difference between damaged hair and sample 8L(6). The mean tensile strengths of all the hairs in the sample bleached at level eight and with oil treatment increased when compared with those of the hairs in the untreated damaged hair cohort. Statistical analysis demonstrated significant differences in hairs 8L(2), 8L(4), and 8L(6) from the sample. The mean absorbance of all hairs in the sample increased when compared with that of the damaged hair, with significant differences noted for hairs 8L(2), 8L(4), and 8L(6) from the sample from damaged hair. Last, the mean glossiness of hairs 8L(2), 8L(4), and 8L(6) from the sample increased with significant differences.Conclusion: Statistical analyses of the mean values between damaged hair and the hairs in the sample treated with oil revealed significant differences in brightness for the hair to which 6 g of noni oil were applied [8L(6)], tensile strength, absorbance, and glossiness. This finding indicates the effects of noni oil on damaged hair in terms of quality. Further studies using a variety of oils and natural extracts in this regard are in order.
Effects of Flavonoids on Skin according to Their Structural Characteristics: A Review
Authors: Lee Jaeeun , Park Seyeon
Published: March 2022

Functional materials with anti-aging properties that prevent aging in the human body in advance have been attracting attention in the pharmaceutical, food, and cosmetic industries, and active research regarding cosmetic ingredients employing flavonoids among such substances is underway. Therefore, this general review assessed previous studies regarding the effect of various flavonoids on the skin according to their structural characteristics. In this study, the antioxidant, whitening, and antiinflammatory effects of flavonoids present in natural extracts were analyzed. Among the flavonoids, the collagen activity enhancing, antioxidant, anti-inflammatory, and whitening effects of apigenin, baicalein, genistein, naringenin, hesperetin, proanthocyanidins, quercetin, and kaempferol were evaluated. In addition, a study conducted to increase the bioavailability of flavonoids by converting them into clathrates using the structural characteristics of β-cyclodextrin, which further analyzed the difference in the effects of glycoside-containing and non-glycoside flavonoids, was reviewed. Another study reported that the 3'-hydroxyl functional group of flavonoids plays an important role in their antioxidant and anti-inflammatory activities; hence, effects consequent to the modification of their molecular structure were expected. Therefore, the studies that suggest that structural modifications can supplement the efficacy of verified flavonoids are considered to be valid. In future, flavonoids may be used as a stable anti-aging material on the basis of this study on their effects on the skin according to their structural characteristics.

Detailed studies of the properties and dating (13 14C dates) of peat sections of the Sherstobitovo and Ubinskoe burnt ryams were carried out. The first data on the dynamics of peat and carbon accumulation in the oligotrophic bogs of the Baraba forest-steppe of West Siberia in the Holocene were obtained. The peat deposits of these sections, respectively, are mixed multilayer forest-swamp and high moor fuscum, 2.5 and 3.47 m thick, 5254 and 6472 cal. years ago, with total reserves of absolutely dry peat – 200 and 267 kg m–2 and carbon – 91 and 124 kg C m–2. The long-term peat accumulation rates are 37.6 and 40.9 g m–2 yr–1, carbon – 17.1 and 19.0 g C m–2 yr–1, the limits of variation of peat accumulation rates in various periods of bog formation are 14.2–78.8 and 14.8–59.0 g m–2 yr–1, carbon – 6.7–32.6 and 6.8–27.5 g C m–2 yr–1. The dependence of peat accumulation dynamics on the hydrothermal climate regimes of the second half of the Holocene, the genesis and age of sections, and the local conditions of their formation is revealed. The confirmed deposition of peats on lake sapropels and organomineral deposits of reed inundated plains occurred after periods of climate aridization. Significant differences between the subsequent dynamics of peat accumulation and presence and location of primary lakes in bog massifs were revealed.

The article is devoted to the theoretical substantiation of new direction in geological exploration of the Bazhenov Formation – the technology of pulsed electromagnetic cross-well exploration, which is based on the idea of involving a system of vertical and horizontal wells drilled in target objects of Lower Cretaceous and Upper Jurassic deposits. The high potential and new capabilities of the proposed technology are demonstrated on realistic models of well sections of the East-Surgut field (Latitudinal Ob Region). Based on the results of numerical simulation, it was found that electromagnetic signals have a high level and sensitivity to the geoelectric parameters of the Bazhenov Formation, which ensures its cross-well exploration at a considerable distance between wells with sources and receivers. The performed research significantly expands opportunities of electromagnetic sounding by the method of transient processes as applied to the tasks of oilfield geophysics in new formulations.

The morphology and chemical composition of minerals of the Khorogochi silver ore occurrence (Upper Amur region) were studied by the analytical scanning electron microscopy. The mineral association is represented by high-grade native silver, basically silver minerals (silver sulphide, sulphoantimonites and silver sulfoarsenides), Ag-containing (fahl ore and galenite), as well as a number of associated minerals (pyrite, chalcopyrite, sphalerite, loellingite, ankerite, hydromica-smectite, etc.). Based on the revealed chemical composition of silver minerals and associated minerals, the features of their spatial relationship, as well as experimental data known from the literature on the resistance of silver-containing systems, the formation temperatures of silver mineralization, which fit into the range of 300–100 oC, and the order of crystallization of its constituent minerals were estimated – from multicomponent compositions with a low silver content (Agtennantite-tetrahedrite, proustite) to compositions with a high content of noble metal (stephanite, polybasite, pearceite, acanthite, native silver). The ore body of silver mineralization in the ore-placer cluster Khorogochi-2 is spatially dissociated from the ore sources of gold-silver mineralization.
Usages et représentations du sauvage

Vingt-cinq séminaires ont été organisés à l’UICN sur les usages et représentations du sauvage. La plupart d’entre eux a tenu à préciser soit les attitudes vis-à-vis du sauvage dans les campagnes qui s’ensauvagent, soit les problèmes de coexistence avec des animaux et végétaux sauvages. Il en résulte que les « gens du lieu » déplorent les friches et boisements spontanés comme autant de stigmates de la déprise agricole et pastorale, de la « désertification » du pays. Ils ne dévalorisent pas le sauvage en soi, mais ne l’apprécient que lorsqu’il n’interfère pas avec l’espace domestique, lorsqu’il ne nuit ni aux récoltes, ni au bétail (par la prédation ou la transmission de maladies). Or, parce qu’il est ingouvernable, le sauvage ne saurait rester à sa place : Les insectes ravagent les récoltes, … et les loups n’hésitent pas à se nourrir de brebis. Comment coexister avec ces sauvages non conviviaux ?
La libre évolution, un concept aux multiples facettes
Authors: Barthod Christian , Dupouey Jean-Luc , Larrère Raphaël , Sarrazin François
Published: March 2022

Après une brève mise au point terminologique et sémantique sur le concept de libre évolution, proche de celui de naturalité, les éditeurs de ce numéro thématique en présentent les enjeux forestiers, la spécificité européenne et les attentes variées et parfois contradictoires des divers acteurs, gestionnaires en charge de la forêt et de l’environnement, scientifiques, associations ou grand public. L’objectif de ce numéro est de leur fournir matière à une réflexion la plus ouverte possible sur un sujet encore en évolution rapide et objet de débats parfois passionnés. Sont ensuite introduits les 18 articles qui abordent, sans viser à l’exhaustivité, diverses facettes de la libre évolution : philosophique, historique, scientifique, technique, politique, culturelle, dans un cadre principalement métropolitain avec quelques éclairages d’autres pays européens. L’émergence, récente à l’échelle du temps des forêts, de la prise en compte de la biodiversité dans la gestion rend ces connaissances nécessaires à l’honnête homme forestier.

Divers travaux menés à différentes échelles concernent la distribution des forêts anciennes et matures, mais il n’existe pas à ce jour de cartographie complète au niveau national. Au niveau européen, le récent rapport du Joint Research Centre de l’Union européenne donne quelques éléments. Au niveau national, la cartographie des forêts anciennes (continuité de l’état boisé) progresse, et parallèlement, le projet CARTNAT envisage le niveau de naturalité toutes occupations du sol confondues. Une récente étude de l’INRAE a permis de modéliser la distribution des forêts selon leur date de dernière exploitation. Les réserves biologiques intégrales créées en forêt publique, maintenues en libre évolution sur 27 000 ha en métropole, ont fait l’objet en 2020 d’un bilan complet de leur contenu en termes d’habitats forestiers. En Nouvelle-Aquitaine, une méthode croisant diverses données géographiques et d’inventaires a permis de situer des zones à fort potentiel de naturalité au sein des forêts anciennes. Les forêts récentes, férales, liées à la recolonisation spontanée par une végétation forestière de zones en déprise font maintenant l’objet d’un suivi spécifique dans les protocoles de l’Inventaire forestier national.
Conservation/préservation de la nature « sauvage » : une histoire des savoirs, des imaginaires et des idéologies (XIXe siècle et première partie du XXe siècle)
Authors: Chalvet Martine
Published: March 2022

Les idées de retour à la nature, de libre évolution, de naturalité connaissent actuellement un certain succès. Mais quelle est l’histoire de ces courants de pensées et de leurs applications concrètes aux États Unis d’Amérique mais aussi dans les États européens et leurs colonies ? Du XIXe siècle à la première moitié du XXe siècle, cet article vise à comprendre comment des courants spécifiques de préservation de la nature se dégagent des autres tendances des mouvements de protection de la nature. À travers l’histoire des savoirs écologiques, mais aussi des dimensions culturelles, identitaires et idéologiques de la nature, nous chercherons à comprendre la circulation des connaissances, des pratiques et des modèles à l’échelle transnationale mais aussi à proposer une histoire nationale des imaginaires, des symboliques et des idéologies de la nature.

This research aims to investigate the carbon fiber reinforced polymer (CFRP) when subjected to tensile, bending, and compression. Half of the specimens are also subjected to water to find out how water influences. The CFRP is created using a combination of carbon fiber layers and epoxy resin Bisphenol A Epichlorohydrin with hardener and is formed using the vacuum infusion method. From the water absorption test, it was found that the average weight gain of the specimens was 2.9% and the lowest value was at 0.6%, it was concluded that the increase in wet specimen weight was not too significant and water absorption tended to be slow. Mechanical testing ob-tained the highest average tensile stress, bending stress, compressive stress, and modulus of elasticity of 195 MPa, 295 MPa, 96 MPa, and 8914 MPa were from dry specimens while the lowest average values were 146 MPa, 286 MPa, 81 MPa, and 6160 MPa from wet specimens. The results of micro-photo observations on the tensile test fracture show that the specimen has a XGM fracture character with delamination and splitting fractures happening in multiple areas. In the bending test, the specimens experienced buckling fracture due to the fiber breaking and the inability of the matrix to withstand the additional stress. Shear fracture happened during the compressive test. In conclusion, water absorption has a bad impact towards the composite strength.
Regional Ombrian Curves: Design Rainfall Estimation for a Spatially Diverse Rainfall Regime

Published: March 2022

Ombrian curves, i.e. curves linking rainfall intensity to return period and time-scale, are well-established engineering tools, crucial to the design against storm waters and floods. Whereas at-site construction of such curves is considered a standard hydrological task, it is a rather challenging one when large regions are of interest. Regional modelling of ombrian curves is particularly complex due to the need to account for spatial dependence together with the increased variability of rainfall extremes in space. We develop a framework for the parsimonious modelling of the extreme rainfall properties at any point in a given area. This is achieved by assuming a common ombrian model structure except for a spatially varying scale parameter which is itself modelled by a spatial smoothing model for the 24 h average rainfall maxima that employs elevation as an additional explanatory variable. The fitting is performed on the pooled all-stations data using an advanced estimation procedure (K-moments) that allows both for reliable high-order moment estimation and simultaneous handling of space-dependence bias. The methodology is applied in the Thessaly region, a 13 700 km2 water district of Greece characterized by varying topography and hydrometeorological properties.
A Robust Second-Order Conic Programming Model with Effective Budget of Uncertainty in Optimal Power Flow Problem
Authors: Zhang Lie , Fakhrabadi Reza D. , Khoshkhoo Maryam , Salama Husien
Published: March 2022

Integrating large-scale wind energy in modern power systems is demanding more efficient mathematical models to properly address classical assumptions in power system problems. In particular, there are two main assumptions in power system problems with wind integration that have not been adequately studied yet; First, non-linear AC power flow equations have been linearized in most of the literature. Such simplifications can lead to inaccurate power flow calculations that may result in other technical issues. Second, wind power uncertainties are inevitable and have been mostly modelled using the traditional uncertainty modelling approaches, that may not be suitable for large-scale wind power integration. In this paper, we address both challenges: we present a tight second-order conic relaxation (SOCR) for optimal power flow (OPF) problem, and simultaneously, implement the new effective budget of uncertainty approach for uncertainty modelling that determines the maximum wind power admissibility first and then addresses the uncertainty in the model. To the best of our knowledge, this is the first study that proposes an effective robust second-order conic programming (ERSOCP) model that simultaneously addresses the issues of power flow linearization and wind power uncertainty with the new paradigm on the budget of uncertainty approach. Our numerical results show the merit of the proposed model against traditional linearized power flow equations as well as traditional uncertainty modelling approaches.

Hubungan antara Minat dengan Hasil Belajar Kartografi
Authors: Adiputra Chandra
Published: March 2022

Penelitian ini dilakukan untuk menganalisis hubungan antara minat dengan hasil belajar mata kuliah Kartografi. Mata kuliah ini dikontrak oleh 19 peserta didik Pendidikan IPS pada semester genap tahun akademik 2020/2021. Data terdiri atas minat terhadap mata kuliah Kartografi (angket) serta hasil belajar mata kuliah Kartografi aspek pengetahuan dan keterampilan (studi dokumentasi). Tidak ada hubungan antara minat dengan hasil belajar Kartografi, baik hasil belajar aspek pengetahuan (rhitung ≤ rtabel = 0,0583 ≤ 0,4555 (n = 17; α = 0,05)) maupun keterampilan (-ttabel ≤ t0 ≤ ttabel = -2,11 ≤ 0,88 ≤ 2,11 (n = 17; ½α = 0,025)). Dengan demikian, peserta didik yang memiliki minat tinggi terhadap mata kuliah Kartografi, belum tentu hasil belajar Kartografinya akan tinggi pula (begitu pun sebaliknya), baik hasil belajar aspek pengetahuan maupun keterampilan. Namun, hasil penelitian ini tidak dapat digeneralisasikan apabila ditinjau dari minat, karena data minat diketahui tidak bervarian homogen (F > F critical one-tail = 1.441,30 > 2,27).

 

This research was conducted to analyze the relationship between interest and learning outcomes of Cartography courses. This course is contracted by 19 Social Studies Education students in the even semester of the 2020/2021 academic year. The data consists of interest in Cartography courses (questionnaire) and learning outcomes of the Cartography course aspect of knowledge and skills (documentation studies). There is no relationship between interest and learning outcomes of Cartography, both learning outcomes aspect of knowledge (rcount ≤ rtable = 0,0583 ≤ 0,4555 (n = 17; α = 0,05)) and skills (-ttabel ≤ t0 ≤ ttabel = -2,11 ≤ 0,88 ≤ 2,11 (n = 17; ½α = 0,025)). Thus, students who have a high interest in Cartography courses do not necessarily have high Cartography learning outcomes (and vice versa), both learning outcomes aspect of knowledge and skills. However, the results of this study cannot be generalized in terms of interest, because interest data is known to have no homogeneous variance (F > F critical one-tail = 1.441,30 > 2,27).

High value utilization of renewable biomass materials is of great significance to the sustainable development of human beings. Because biomass contains large amounts of carbon, they are ideal candidates for the preparation of carbon nanotube (CNT) fibers. However, continuous preparation of CNT fibers using biomass as carbon source remains a huge challenge due to the complex chemical structure of biomass. Here, we develop high-performance CNT fibers from lignin by solvent dispersion, high-temperature pyrolysis, catalytic synthesis, and assembly, and realize continuous preparation of CNT fibers. The CNT fibers exhibit a tensile strength of 1.35 GPa and an electrical conductivity of 6.28×105 S m− 1, superior to that of most biomass-derived carbon materials. More importantly, we achieve an unprecedented continuous production of CNT fibers from biomass with a production rate of 120 m h− 1. Our preparation method is extendable to other biomass materials and will greatly promote the high value application of biomass in a wide range of fields.
