description: Abstract: The results of an inventory and evaluation of wetlands of north-eastern Poland (the Olsztyn region) carried out are presented in the paper. A description of the occurrence, utilisation, vegetation and protection of wetlands was produced. The main results of this project are: a wetland map of Poland in the scale of 1:100 000, a database of wetlands and new proposals designed for the legal protection of wetlands. The investigated Olsztyn region was divided into three zones (northern - flat, middle - moraine, south - outwash plain) in which wetlands exhibit specific characteristics.
description: Zusammenfassung: Die Arbeit stellt Ergebnisse einer Bestandsaufnahme und einer Bewertung von Feuchtgebieten im nordöstlichen Teil Polens in der Olsztyner Region vor. Man hat Feuchtgebiete untersucht und zwar Vorkommen, Nutzung, Pflanzendecke und Schutz. Das Ergebnis ist in Karten im Maßstab 1:100 000 mit Erläuterungen dargestellt, die auch Vorschläge für Schutzgebiete enthalten. Das Gebiet von Olsztyn wurde in drei Zonen gegliedert (eine flache Zone im Norden, eine mittlere Moränenhöhenenzone und eine Zone sanderartiges Flachland im Süden), in denen sich die Feuchtgebiete erheblich voneinander unterscheiden.

description: Hölzer hat die im Naturschutz laufenden Bemühungen um die Renaturierung und Wiedervernässung von Hochmooren, die in der Regel mit dem Ziel einer möglichst weitgehenden Regenerierung angestellt werden, generell in Frage gestellt. Die Gründe für die genannten Bemühungen werden genannt. Es wird dargestellt, daß trotz einiger fehlerhaft angelegter Vorhaben diese Aktivitäten für den Naturschutz von großer Bedeutung sind.
description: Hölzer has criticised the attempts of nature conservancy to renaturate and rewet raised bogs with the aim of regenerating them as far as possible. The reasons for these attempts are discussed. It is pointed out that in spite of some projects which indeed were not sufficiently planned, these nature conservancy activities are of great importance.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this paper we examine Casimir effect in the case of tachyonic field, which is connected with particles with negative four-momentum square. We consider here only the case of one dimensional, scalar field. In order to describe tachyonic field, we use the absolute synchronization scheme preserving Lorentz invariance. The renormalized vacuum energy is calculated by means of Abel-Plana formula. Finaly, the Casimir energy and Casimir force as the functions of distance are obtained. In order to compare the resulting formula with the standard one, we calculate the Casimir energy and Casimir force for massive, scalar field.

Das Bollenfenn in Berlin-Tegel
The Mire ”Bollenfenn” in Berlin-Tegel
Creators: name: Brande, Arthur
Publisher: name: FID GEO
Year: 1988

description: Das 1 ha große Bollenfenn ist ein tiefes Randmoor des Tegeler Sees. Es hat sich als meso- bis eutrophes Verlandungsmoor und seit der mittelalterlichen Seespiegelanhebung als mesotrophes Versumpfungsmoor entwickelt. Anthropogene Degradation zum Erlenbruch im 20. Jahrhundert beeinträchtigt durch Vererdung des Torfes die pollenanalytischen Befunde der Neuzeit. Daten zur Geschichte der Natur- und Kulturlandschaft ergeben sich nur unter Einbeziehung weiterer Untersuchungspunkte, besonders des Tegeler Sees. Der Pollenniederschlag der seit zwei Jahrhunderten besonders laubholzreichen Umgebung tritt vor dem Hintergrund kiefernreicher Wälder am ehesten mit den Eichen etwas hervor. Beziehungen des Untersuchungsgebietes und der Methoden seiner Erforschung zu A.von HUMBOLDT werden hervorgehoben. Eine künftige Pflege und Entwicklung des Moores ist aus garten- und kulturlandschaftsgeschichtlichen Gründen und den Erfordernissen des Naturschutzes im großstädtischen Raum geboten.
description: The 1 hectar large Bollenfenn is a deep marginal mire of the Tegel lake. It has developed as a lake-originated meso- to eutrophic overgrowing mire, and since the medieval artificial lake level rise as a mesotrophic paludifying mire. Anthropogenic degradation to an alderfen in the 20th century influences the palynological evaluation of modern times due to peat perturbation. Results on the natural and cultural landscape development include investigations of other nearby sites, especially of the Tegel lake. The pollen precipitation of the surrounding area, which is extremly rich in deciduous woodland since about 200 years, is obviously underrepresented on the background of large pine-rich woodlands, though less pronounced in oak. Relationship of the investigation area and the methods of its investigation to A. von HUMBOLDT are expressed. A management and development of the mire in the future is proposed by reasons of garden and landscape history and by demands of nature conservation in the large city region of Berlin.

Darlington
Creators: name: Frazier, Shawn
Publisher: name: American University
Year: 2023

description: Darlington is a collection of short stories showing the effects of lynching in the past, present and future. These stories and poetry are infused with elements of magical realism, fantasy and science-fiction. I chose to write this narrative through these literary genres because they allow me the freedom to move creatively. Speculative fiction (magical realism, science-fiction and fantasy), permits people to be aware of things that "realistic" literature isn't always able to do. The narratives revolve around a small imaginary town in American and shows how lynching impacts a community over a period of time. By mixing various literary genres and styles, I sought to explore a horrific period in America by showing how various generations within a community have dealt with this dilemma. Often stories that have explored lynching, have examined how it has affected and divided the black community. Darlington attempts to show different prospective on the subject and how the victim and victimizer are forever linked by this tragedy. The chapters in Darlington are called suites to illustrate a linkage that exist with each story. The stories in Darlington are not self contain, but are influenced by previous and ongoing events in the town.
The productivity discourse: constructing the economies of France and the United States during the 20th century
Creators: name: Hiebert, Heidi
Publisher: name: American University
Year: 2023

description: The productivity discourse, constructing the economies of France and the United States during the 20th century analyzes the way in which mathematical models of productivity - as well as the rhetoric of productivity - powerfully influenced policy-making in France and the United States during the last century. The research reveals that social meanings attached to the concept of productivity, and the lens through which we attribute the source of productivity growth shifted, over time, and that these shifts related to changes in the social context. The larger finding exposes the potency of economic indicators to act as organizing principles, with the research showing how countries respond to changes in their relative rankings. The dissertation research is premised on the assumption that the productivity discourse would neutralize divisive interests because of its promise that "more" would be available for less - and for all. The evidence collected from public debates in France and the United States suggests this presumption to be clearly correct. The research additionally reveals the sheer competitive force of a country's relative productivity ranking as an economic organizing principle. Because the numbers and models used to conceptualize productivity tend to shift with changes in the social context, essentialist properties of productivity are placed in doubt, thereby providing the grounds for novel interpretations about how economies are constructed and become transfigured over time. The fact that social meanings attached to productivity translated fairly well across two countries - France and the United States - with very different institutional configurations, more fundamentally, reveals the power of ideas as organizing principles in economies and presents a challenge to the Varieties of Capitalism literature.
Blending palm oil with flaxseed oil or menhaden fish oil to produce enriched omega-3 oils for deep-fat-frying
Creators: name: Soewono, Adri A.
Publisher: name: University of British Columbia
Year: 2011

description: Two of the major dietary food sources of omega-3 fatty acids are flaxseed oil and fish oil; the former being a rich source of PUFA (e.g. α-linolenic acid (α-LA)), while the latter is a source of HUFA (e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)). In this study, palm oil, a commonly used vegetable oil that is widely available in Asian and African countries, was blended with flaxseed (omega 3-PUFA) and fish oil (menhaden oil) (omega-3 HUFA); respectively, to obtain blended oils that both contained a 1: 4 ratio of omega-3 :omega 6 fatty acids. Rosemary extract (0.02% w/w) was added to the oil blends to stabilize the oil during use for deep-fat frying. Eight hours of heating at 180 °C was used to determine the stability of omega-3 fatty acids and uptake from the omega-3 enriched palm oil into fried potatoes. Lipid oxidation and thermal degradation of the palm oil blends, along with retention of α-LA , EPA, and DHA were measure of oil blends stability. Linoleic acid content in flax-palm oil blend did not change during frying when in the presence of different antioxidant treatments. The α-LA content of heated flax-palm oil blend was significantly reduced (P<0.05) after 8 hours of frying. Meanwhile, linoleic acid and EPA content in the fish-palm oil blend revealed significant (P<0.05) decreases in concentration after 8 hours of frying regardless of the presence of antioxidant. The DHA concentration was significantly lower when present in the absence of antioxidant (P<0.05). Totox significantly increased (P<0.05) in the blended oils after 8 hours of frying; albeit the extent of oxidation and thermal degradation was reduced when rosemary extract was added. A significant uptake of omega-3 fatty acids in both the omega-3 PUFA (e.g. α-LA) and HUFA (e.g. EPA and DHA), respectively, occurred in potatoes fried in the respective blended oils. Although omega-3 fatty acid uptake was prevalent in potatoes fried in both blended oils, the effect of heating reduced the optimal 1:4 ratio of omega-3 :omega-6 to a 1:6-l :7 ratio. This loss in omega-3, relative to omega- 6, was attributed to thermal oxidation; a reaction not totally preventable by adding antioxidants to the frying oils. These functional omega-3 enhanced oils when used to process potatoes gave forth products that represented 1/10th suggested intake for EPA+DHA and l/50th the daily requirement for α-LA .

description: The main objective of the study was a comparative analysis of the diversity of the agrarian structure and the productivity of land and labour in the Visegrad Group countries. Additionally, the importance of the Visegrad Group in the European Union was analysed in relation to the size of the production of selected crops and livestock as well as the population and cast of cattle and pigs. According to the conducted analyses, the highest productivity of land among the countries of the Visegrad Group was shown in the years under study by Poland and Hungary (over EUR 600 / ha AL), while the highest dynamics of the growth rate of this parameter - by Slovakia (almost two-fold increase in 2010-2013). Taking into account labour productivity, it should be emphasized, that the greatest labour productivity characterized farms in the Czech Republic and Slovakia. Synopsis. Głównym celem pracy było porównanie zróżnicowania struktury agrarnej oraz produktywności ziemi i pracy w krajach Grupy Wyszehradzkiej. Dodatkowo analizie poddano znaczenie Grupy Wyszehradzkiej w Unii Europejskiej w odniesieniu do wielkości produkcji wybranych ziemiopłodów oraz pogłowia i obsady bydła a także trzody chlewnej. Jak wynika z przeprowadzonych analiz, najwyższą spośród państw Grupy Wyszehradzkiej produktywnością ziemi odznaczały się w badanych latach Polska i Węgry (ponad 600 euro/ha UR), z kolei największą dynamiką wzrostu tej wielkości – Słowacja (niemal dwukrotny wzrost w latach 2010-2013). Biorąc pod uwagę produktywność pracy należy podkreślić, że największą wydajnością pracy charakteryzowały się gospodarstwa rolne w Czechach i na Słowacji.

description: The aim of the article was to determine the changes in foreign trade of farm machinery in Poland in 2004-2015. The article presents the value of exports and imports of farm machinery in total, according to geographical area, as well as for selected types of agricultural machinery. The article uses secondary data from the Ministry of Finance, gathered as part of the Integrated Customs Tariff Information System. In the analyzed period, Poland was characterized by a negative balance of foreign trade. The value of imports of farm machinery increased more than threefold, while the value of exports nearly quadrupled. In 2015, Poland exported most of its farm machinery to the EU-28 (65% of export value), especially to Germany, France and Belgium. Within the EU-28, Poland is also the most imported (87% of import value), and its main trade partners were Germany, Italy and France. Celem artykułu było określenie zmian w handlu zagranicznym środkami mechanizacji rolnictwa w Polsce w latach 2004-2015.

description: Die Akkumulation von Kohlenstoff und Stickstoff ist das prägende Merkmal von Mooren. Mit dem Wasser- und Stickstoffhaushaltsmodell WASMOD werden für ein degeneriertes Verlandungsniedermoor Eintrag und Austrag von Stickstoff quantiﬁziert. Neben den Ernteentzügen wirken vor allem gasförmige Verluste über Denitriﬁkation stickstoffzehrend. Die flächenhafte Darstellung der Quellen-Senkenwirkung verdeutlicht, daß in der Simulation der überwiegende Anteil der Niedermoorböden in der Pohnsdorfer Stauung als Stickstoffquelle wirkt. Akkumulierende Bereiche treten nur kleinflächig auf. Diese Simulationsergebnisse können die Basis für ein zukünftiges Managementkonzept bilden.
description: The accumulation of carbon and nitrogen is an important natural property of mires. In this study, the input and output of nitrogen of a degenerated fen of lacustrine origin are quantified with the water- and nitrogen model WASMOD. Nitrogen gaseous losses by denitrification belong with harvest to the most important output sources. The spatial visualisation of the source and sink function clearly indicates, that actually the majority of the peatsoils in the Pohnsdorfer Stauung acts as nitrogen source. In the simulation only small areas accumulate nitrogen. These simulation results can be used to develop a more sustainable management in the future.

Age-Related Differences in the Retrieval and Definition of Events from Memory
Creators: name: Hohman, Timothy J.
Publisher: name: American University
Year: 2023

description: Older adults often struggle to recall events from a specific time and specific place when presented with a cue word (Piolino et al., 2010). When they are able to successfully retrieve an event, they tend to recall fewer specific details, focusing instead on contextual and factual information (Levine, Svoboda, Hay, Winocur, & Moscovitch, 2002). These age differences are not relegated to the retrieval scenario alone; at encoding older adults also show differences in the way they segment ongoing information into discrete events (Zacks, Speer, Vettel, & Jacoby, 2006). The present work investigated age differences in the retrieval and definition of events from memory. First we delineated the age differences in neural activity during autobiographical recall. Second, we established how age alters event definitions during retrieval. Finally, we explored whether a more global change in event understanding could account for age differences in event memory. Our results highlight key differences in brain activity during autobiographical memory retrieval in the prefrontal cortex and anterior cingulate, and in the functional connectivity between these regions and the hippocampus. Further, our results demonstrate age differences in event definitions during perception and retrieval. We conclude by highlighting how these findings relate to the processes of memory retrieval and event segmentation.

description: In our work we have reconsidered the old problem of diffusion at the boundary of ultrametric tree from a "number theoretic" point of view. Namely, we use the modular functions (in particular, the Dedekind eta-function) to construct the "continuous" analog of the Cayley tree isometrically embedded in the Poincare upper half-plane. Later we work with this continuous Cayley tree as with a standard function of a complex variable. In the frameworks of our approach the results of Ogielsky and Stein on dynamics on ultrametric spaces are reproduced semi-analytically/semi-numerically. The speculation on the new "geometrical" interpretation of replica n->0 limit is proposed.

Patterns of Foreign Direct Investment. An Investigation of FDI in Poland
Creators: name: Kochut, Renata
Publisher: name: American University
Year: 2023

description: Globalization emerged as a very important trend reshaping the economic landscape. One of the major drivers of this process is free capital flow between the geographical regions. In this new competitive environment it is crucial for both the companies and the policy makers to gain a good understanding of Foreign Direct Investment (FDI) processes. In particular, what features of a region are important in attracting and retaining FDI and what are the temporal patterns in FDI development. The novelty of the approach lies in discovering the inter-industry and temporal dependencies in FDI and also in separate analysis of several industry segments. The results give new insights into the location choice patterns used by different types of companies. Also, to the best of my knowledge, it is the first empirical study of the time evolution of the FDI; especially in a sense of what kinds of prior investments influence later ones. The research is conducted at powiat level of territorial division in Poland.

description: Die Rekultivierung von Abbaugebieten für Belange des Naturschutzes (Biotopneuschaffung) und die Pflege von Gebieten mit Sekundärgesellschaften, d.h. die Erhaltung eines bestimmten Zustandes, sind notwendige Ziele des Naturschutzes, die auch für Moore gelten. Die Rekultivierung für den Naturschutz darf jedoch nicht als "Alibi" für einen Abbau herangezogen werden. Pflegeprogramme bedürfen einer sorgfältigen Begründung durch Konzepte des Arten- und Gesellschaftsschutzes, Die natürliche Entwicklung von Beständen verändert zwar ein gewohntes Landschaftsbild, ist aber in vielen Fällen ökologisch nicht negativ zu werten.
description: Management of nature reserves(secondary paludification, grazing, burning etc.) and the regeneration of peat cutting areas, gravel pits etc. are goals of the nature conservancy, landscape planning authorities and private organizations. The planning of new biotopes is no alibi for the exploitation of sites of ecological importance. The management is prerequisite for the conservation of special species and ecosystems. In Southern Germany special problems are meadows of valley bogs (Molinion, Caricion davallianae, Caricion fuscae). In many cases the development of secondary ecosystems gives more aesthetical than ecological problems.

 Vietnamese glomerid species are assigned to five genera: Annameris, Hyleoglomeris, Hyperglomeris, Peplomeris, and Rhopalomeris. While currently close to 100 species of Hyleoglomeris range from the Balkans to Indonesia, members of the genera Annameris (2 species), Hyperglomeris (7 species), and Peplomeris (2 species) are known only from Vietnam. The three species in the genus Rhopalomeris range from Malaysia to northern Vietnam. Three Vietnamese glomerid species are known from females only: R. tonkinensis, A. robusta, and H. triangulifera. Eight species described in the last century (by Verhoeff, Attems, and Silvestri) are known from their type specimen only, and have never been re-collected. Species distributions for these glomerids are unexplored. For the 12 more recently described species, only Peplomeris magna has been recollected twice (see below) in the same geographic region as the original type material. Thus, the current distribution patterns are strongly biased and reflect the limited collecting effort. Due to the lack of specimens for most Vietnamese glomerid species, morphological intra-specific variability cannot be ascertained. Furthermore, the type specimens of the species described by Silvestri, Verhoeff, and Attems have never been examined during more recent work on the group, allowing at most tentative synonymy suggestions (for H. electa and H. maior). Providing a basis for future research with comparative material, numerous illustrations of somatic characters, as well as telopods and vulval features are given here for P. magna, and Hyleoglomeris lobus, new species.

Patterns of Foreign Direct Investment. An Investigation of FDI in Poland
Creators: name: Kochut, Renata
Publisher: name: ProQuest
Year: 2023
Subjects: classificationCode: 38
subject: Economics

description: Globalization emerged as a very important trend reshaping the economic landscape. One of the major drivers of this process is free capital flow between the geographical regions. In this new competitive environment it is crucial for both the companies and the policy makers to gain a good understanding of Foreign Direct Investment (FDI) processes. In particular, what features of a region are important in attracting and retaining FDI and what are the temporal patterns in FDI development. The novelty of the approach lies in discovering the inter-industry and temporal dependencies in FDI and also in separate analysis of several industry segments. The results give new insights into the location choice patterns used by different types of companies. Also, to the best of my knowledge, it is the first empirical study of the time evolution of the FDI; especially in a sense of what kinds of prior investments influence later ones. The research is conducted at powiat level of territorial division in Poland.

description: Genus Hyperglomeris Silvestri, 1917
 Type species. Hyperglomeris lamellosa Silvestri, 1917: 146, by original designation.
 Remarks. The Vietnamese endemic genus Hyperglomeris Silvestri, 1917 is restricted to northern Vietnam, with seven species. All Hyperglomeris species are known exclusively from their type localities, and the distribution of the genus is still poorly known. There are no species that have been recorded in central and southern parts of the country. The genus is very similar to Peplomeris in having only prefemoral trichosteles, and femoral trichosteles strongly reduced or absent on telopods. Hyperglomeris differs from Peplomeris by having antennae with four large, apical sensory cones.
 A key to identify Hyperglomeris species was recently provided by Golovatch (2017).

Die landwirtschaftliche Nutzung von Mooren in Nordwestdeutschland
The agricultural use of peatlands in northwest Germany
Creators: name: Blankenburg, Joachim

Year: 2015

description: Die meisten Moore in Nordwestdeutschland werden seit mehreren Jahrhunderten landwirtschaftlich genutzt. Die Kultivierungsverfahren der Moore entscheiden, welche Nutzungen möglich sind. Tiefumbruchböden lassen sich vielfältig, überwiegend als Acker nutzen. Auf den Schwarzkulturen dominiert heute die standortgerechte Grünlandnutzung, wobei die nicht standortgerechte, ackerbauliche Nutzung in jüngster Zeit zugenommen hat. Mit zunehmender Intensität der Flächenbewirtschaftung verschlechtern sich die Torfeigenschaften und durch Mineralisierung der Torfe treten Höhenverluste auf. Die Grenzen der Befahrbarkeit bzw. Trittfestigkeit werden häufig erreicht. In der Nährstoffdynamik unterscheiden sich Hoch- und Niedermoore. Bei der extensiven Grünlandnutzung, verbunden mit reduzierter Entwässerungsintensität, bereiten häufig Flatterbinse (Juncus effusus) und Rasenschmiele (Deschampsia caespitosa) Probleme. Neue Nutzungsverfahren der Paludikultur befinden sich noch in der Entwicklung und Erprobung. Eine dauerhafte Sicherung der Produktionsstandorte für landwirtschaftliche Nutzungen ist auf Tiefumbruchböden möglich.

description: The DC transport properties of and the radio-frequency (RF) wave absorption (at 2.525 MHz) in a sample of La$_{0.67}$Sr$_{0.33}$MnO$_{3}$ prepared by floating-zone method are measured. The Curie temperature, $T_{c}$, of the sample is about 374 K. Giant temperature and magnetic-field variations in RF absorption are found in the vicinity of $T_{c}$. Relative change of the RF absorption in magnetic field (magnetoabsorption) is about 67% in field 2.1 kOe and about 55% in field 1 kOe. This giant magnetoabsorption effect can be used to develop RF devices controlled by temperature and low magnetic field. A weak temperature dependence of magnetoabsorption for the sample studied in the range from room temperature to about 350 K makes it especially attractive for practical use. The RF study supplemented with transport, magnetoresistive and magnetic measurements enables us to discuss the optimal properties of manganite samples for observation of giant magnetoabsorption in low field.

title: Links between social deprivation and harm to children: a study of parenting in social disadvantage
Creators: name: Tuck, Victor David
Publisher: name: The Open University
Year: 1995

description: What is the nature of the links which may exist between social deprivation and harm to children? In seeking to shed light on the nature of these links this thesis will draw upon a study of parents' perceptions of the problems faced by them in bringing up children in neighbourhoods characterised by high scores on indices of social deprivation and high levels of child protection registrations. It will be demonstrated that parents facing social disadvantage encounter a range of adversities and hindrances which may have a cumulative adverse effect upon the care of children. The problems to which these lead will be shown to be linked by three main strands:- - social deprivation contributes to the existence of socially and economically impoverished neighbourhoods in which it is difficult for parents to provide a safe and healthy environment for children - by creating material, social, interpersonal and intrapersonal barriers in families, social deprivation can prevent parents from achieving the standards of parenting to which they might aspire and which society expects of them - in interaction with many other factors, social deprivation can contribute to high levels of psychosocial stress within families that may lead some parents to physically injure or neglect their children. In these ways the study will develop the argument that harm to children is linked to deficits in material resources and complex, interacting psychosocial stress factors. The study will be seen to have major implications for service-provision under the Children Act 1989 and promoting "partnership with parents".
Consistent S^2 Pauli Reduction of Six-dimensional Chiral Gauged Einstein-Maxwell Supergravity

description: Six-dimensional N=(1,0) Einstein-Maxwell gauged supergravity is known to admit a (Minkowski)_4\times S^2 vacuum solution with four-dimensional N=1 supersymmetry. The massless sector comprises a supergravity multiplet, an SU(2) Yang-Mills vector multiplet, and a scalar multiplet. In this paper it is shown that, remarkably, the six-dimensional theory admits a fully consistent dimensional reduction on the 2-sphere, implying that all solutions of the four-dimensional N=1 supergravity can be lifted back to solutions in six dimensions. This provides a striking realisation of the idea, first proposed by Pauli, of obtaining a theory that includes Yang-Mills fields by dimensional reduction on a coset space. We address the cosmological constant problem within this model, and find that if the Kaluza-Klein mass scale is taken to be 10^{-3} eV (as has recently been suggested) then four-dimensional gauge-coupling constants for bulk fields must be of the order of 10^{-31}. We also suggest a link between a modification of the model with 3-branes, and a five-dimensional model based on an S^1/Z_2 orbifold.

description: We propose an efficient variational method for $Z_2$ lattice gauge theory based on the matrix product ansatz. The method is applied to ladder and square lattices. The Gauss law needs to be imposed on quantum states to guarantee gauge invariance when one studies gauge theory in hamiltonian formalism. On the ladder lattice, we identify gauge invariant low-lying states by evaluating expectation values of the Gauss law operator after numerical diagonalization of the gauge hamiltonian. On the square lattice, the second order phase transition is well reproduced.
