In the endeavor to ascertain the influence of some specific weather and climatic factors on the sucrose content of sugarcane at harvesttime in Puerto Rico, data on past crops of such commercial varieties as, P.R. 902, M. 28, P.R. 905, P.O.J. 2878, and others, were re-examined and re-evaluated. There were significant variations in the sucrose content of the same varieties when grown in the same regions in different crop years. These variations were related to weather conditions. Canes harvested at southern irrigated plantations with low rainfall consistently yielded more sucrose than those grown elsewhere, while those grown in the west were higher in sucrose than those grown in the interior, north, or east. In the former region field-irrigation schedules provide for a drying out of the cane from 45 to 60 days before harvest, while the cane was normally harvested during the drier season of the year in the other regions mentioned.

Data are presented here on the effect of applications of 2,4-D and maleic hydrazide to sugarcane at intervals prior to harvesttime. Field experiments were conducted at Río Piedras in northern Puerto Rico and at Colonia Río Grande, between Caguas and Gurabo, in east-central Puerto Rico. Daily fluctuations in Brix, polarization, purity, and available 96° sugar percent cane were followed for 46- and 72-day periods, respectively. No significant differences were observed between the mean available 96° sugar percent cane that could be ascribed to treatments. Seasonal variations and variations attributable to weather conditions were rather important factors at both locations.

Shakespeare’s tragedies are among the most analyzed and discussed literary works. In his tragedies Shakespeare follows the Aristotelian pattern of drama, so it is easy to notice there all the elements of a tragedy presented in Aristotle’s Poetics. In this paper I will define what climax in literature is and explore the climax of one of the four great tragedies of Shakespeare, that of King Lear. As a masterfully structured play, the central part of the play is the climax itself. But what is the climax of this play, how is it presented, does it have any impact on the characters, how does it change the course of events, etc? Answers to these questions will be given here. As an example of the interactions between men and weather conditions in Shakespeare’s drama, I will explore climate as climax. The climactic moment of the play is the storm, in the 3rd act, when we see the psychological rage of King Lear. Unsurprisingly, Shakespeare exposes the issue of how the local weather durably affects the nature of men as well as by the way their humours are temporarily changed by climate and environment. Yet, I will argue that this issue actually prompts him to reverse traditional points of view in order to show that things also work the other way round. Indeed, in some of his plays, the playwright insists on men’s unfortunate capacities to provoke violent climactic disorders and to generate chaos on earth. So, it is not only the weather and climate that affect the behaviour and humour of people, but the way people feel and behave. The case with King Lear is a perfect example of this problem. The storm that Lear finds himself is actually reflected in his inner state, in his psychological rage due to his disappointment with his two daughters, and facing with the harsh reality for a father, but mostly for being unjust to his younger daughter, Cordelia.

Climate prediction is given a high priority by many countries due to its importance in mitigation of extreme weather conditions. However, the prediction is not an easy task as the climatic parameters not only show spatial variations but also temporal variations. In addition, the climatic parameters are interrelated. To overcome these difficulties, soft computing techniques are widely used in prediction of climate variables with respect to the other variables. On the other hand, Colombo, Sri Lanka, is experiencing adverse or extreme weather conditions over the last few years. However, a climate prediction study is yet to be carried out in this tropical climatic zone. Therefore, this paper presents a study, identifying relationships between the two most impacted climate parameters (atmospheric temperature and rainfall) and other climatic parameters. Artificial neural network (ANN) models are developed to define the relationships and then to predict the atmospheric temperature as a function of other parameters including monthly rainfall, minimum and maximum relative humidity, and average wind speed. Same analysis is carried out to define the prediction model to the monthly rainfall. The best algorithm out of several other ANN algorithms is chosen for the analyses. Results revealed that the atmospheric temperature in Colombo can be presented with respect to the other climatic variables. However, the rainfall does not show a greater relationship with the other climatic parameters.

Plants of two sapogenin-bearing Dioscorea species propagated by two different techniques, were tested at different locations in Puerto Rico over a 3-year period. In an experiment at Mayagüez plants grew best in a loose, well-drained soil, planted on flat beds rather than ridges, and without the addition of organic material (cachaza). In plots at Isabela, Corozal, and Adjuntas sapogenin yields were higher in the Isabela loam than in the heavier clay soils at the other locations. Plants propagated from stem cuttings gave better results in D. floribunda plantings; propagations from tuber pieces gave better results with D. composita. In these trials the propagation method and the effects of climate and soil influenced plant growth and tuber yields, but had little effect on the percentage of sapogenin developed in the tubers. Location effects on total sapogenin production resulted in most cases from differences in tuber yield, rather than in percentage sapogenin. These were the largest controlled experiments conducted with sapogenin-bearing species in Puerto Rico. Although these tests indicate that they are satisfactorily adapted to a wide range of conditions, it is clear that best yields are obtained in good, well-drained soils. Sapogenin yields were sufficiently high to be commercially valuable in all locations tested.

Ahmet Hamdi Tanpinar (1901-1962) is one of the most controversial authors in the 20th century Turkish literature. Literature critics find it difficult to place him in a school of literature and thought. There are many reasons that they have caused Tanpinar to give the impression of ambiguity in his thoughts through his literary works. One of them is that he is always open to (even admires) the "other" thought to a certain age, and he considers synthesis thinking at later ages. Tanpinar states in the letter that he wrote to a young lady from Antalya that he composed the foundations of his first period aesthetics due to the contributions from western (French) writers. The influence of the western writers on him has also inspired his interest in the materialist culture of the West. In 1953 and 1959 he organized two tours to Europe in order to see places where Western thought and culture were produced. He shared his impressions that he gained in European countries in his literary works. In the literary works of Tanpinar, Europe comes out as an aesthetic object. The most dominant facts of this aesthetic are music, painting, etc. In this work, in the writings of Tanpinar about the countries that he travelled in Europe, some factors were detected like European culture, lifestyle, socio-cultural relations, art and architecture, political and social history and so on. And the effects of European countries were compared with Tanpinar’s thought and aesthetics. Keywords: Ahmet Hamdi Tanpinar, Europe, poetry, music, painting, culture, life

Transnational films representing intimacy and inequality disrupt and disgust Western spectators. When wounded bodies within poverty entangle with healthy wealthy bodies in sex, romance and care, fear and hatred combine with desire and fetishism. Works from the Philippines, South Korea, and independents from the United States and France may not be made for the West and may not make use of Hollywood traditions. Rather, they demand recognition for the knowledge they produce beyond our existing frames. They challenge us to go beyond passive consumption, or introspection of ourselves as spectators, for they represent new ways of world-making we cannot unsee, unhear, or unfeel. The spectator is redirected to go beyond the rapture of consuming the other to the rupture that arises from witnessing pain and suffering. Self-displacement is what proximity to intimate inequality in cinema ultimately compels and demands so as to establish an ethical way of relating to others. In undoing the spectator, the voice of the transnational filmmaker emerges. Not only do we need to listen to filmmakers from outside Hollywood who unflinchingly engage the inexpressibility of difference, we need to make room for critics and theorists who prioritize the subjectivities of others. When the demographics of filmmakers and film scholars are not as diverse as its spectators, films narrow our worldviews. To recognize our culpability in the denigration of others unleashes the power of cinema. The unbearability of stories we don’t want to watch and don’t want to feel must be borne.

The purpose of the present study is to investigate the impact of rain, snow and hail on potential gradient (PG), as observed in a period of ten years in Xanthi, northern Greece. An anticorrelation between PG and rainfall was observed for rain events that lasted several hours. When the precipitation rate was up to 2 mm/h, the decrease in PG was between 200 and 1300 V/m, in most cases being around 500 V/m. An event with rainfall rates up to 11 mm/h produced the largest drop in PG, of 2 kV/m. Shortly after rain, PG appeared to bounce back to somewhat higher values than the ones of fair-weather conditions. A decrease in mean hourly PG was observed, which was around 2–4 kV/m during the hail events which occurred concurrently with rain and from 0 to 3.5 kV/m for hail events with no rain. In the case of no drop, no concurrent drop in temperature was observed, while, for the other cases, it appeared that, for each degree drop in temperature, the drop in hourly mean PG was 1000 V/m; hence, we assume that the intensity of the hail event regulates the drop in PG. The frequency distribution of 1-minute PG exhibits a complex structure during hail events and extend from −18 to 11 kV/m, with most of the values in the negative range. During snow events, 1-minute PG exhibited rapid fluctuations between high positive and high negative values, its frequency distribution extending from −10 to 18 kV/m, with peaks at −10 and 3 kV/m.

Ideologically motivated attempts to elucidate Shostakovich’s political views and to determine whether and how they may be coded into his compositions have come to characterize the Western reception of the composer’s works since his death in 1975. Fuelled by the political oppositions of the cold war, Shostakovich’s posthumous reputation in the West has been largely shaped by two conflicting perspectives. These have positioned him on the one hand as a secret dissident, bent and broken under the unbearable strain of totalitarianism, made heroic through his veiled musical resistance to Communism; and on the other hand as a composer compromised by his capitulation to the regime – represented in an anachronistic musical style. Both perspectives surrender Shostakovich and his music to a crude oversimplification driven by vested political interests. Western listeners thus conditioned are primed to hear either the coded dissidence of a tragic victim of Communist brutality or the sinister submission of a ‘loyal son of the Communist Party’.1 For those prepared to accept Shostakovich as a ‘tragic victim’, the publication of his purported memoirs in 1979, ‘as related to and edited by’ the author Solomon Volkov, presents a tantalizing conclusion: bitterly yet discreetly scornful of the Stalinist regime, Shostakovich was indeed a secret dissident and this dissidence was made tangible in his music.

The essay shows how Ezenwa–Ohaeto's poetry in pidgin, particularly in his collection (1988), emblematizes a linguistic interface between, on the one hand, the pseudo-pidgin of Onitsha Market pamphleteers of the 1950s and 1960s (including in its gendered guise as in Cyprian Ekwensi) and, on the other, its quasicreolized form in contemporary news and television and radio dramas as well as a potential first language. While locating Nigerian Pidgin or EnPi in the wider context of the emergence of pidgins on the West African Coast, the essay also draws on examples from Joyce Cary, Frank Aig–Imoukhuede, Ogali A. Ogali, Ola Rotimi, Wole Soyinka, and Tunde Fatunde among others. It is not by default but out of choice and with their 'informed consent' that EnPi writers such as Ezenwa–Ohaeto contributed to the unfinished plot of the pidgin–creole continuum.

ON March 7, 1936, German troops entered the demilitarized zone of the Rhineland. Germany thus violated Articles 42 and 43 of the Treaty of Versailles and Articles 1 and 2 of the Treaty of Locarno of 1925. Remilitarization moved forward for about one hundred miles the areas of concentration for any German armed attack in the west and advanced the defensive line that could be held by the German army. It severely weakened France and, in consequence, all the other powers concerned to maintain the Paris peace settlements and to preserve the peace of Europe.
