Between 2005, 2014–2017, we studied six Elegant Euphonia (Euphonia elegantissima) nests from two sites (urban and suburban) in the city of Xalapa, Veracruz. They were located in a macadamia tree crown, under epiphytic bromeliads, and under hanging fern and Euphorbia pots. The two nests we extracted and measured (7.2 x 7.5 x 5.6 cm; 10.1 x 8.6 x 11 cm), were closed and globular, with a lateral entry and mainly made of plant fibers, leaves, and cobwebs. Our observations included nest construction, egg incubation and chick care (nestling phase). Nest construction took at least 10–11 days, while egg incubation took 14–18 days. Incubation was done by the female in all but one observation, and the male escorted the female to the nest on every occasion. Time of incubation sessions ranged from 36–88 min (mean = 62 min) with shorter out nest sessions (3–18 min, mean = 9 min). There were three eggs in two of the nests, and in one only two eggs hatched; four chicks were observed in another nest. The nestling phase lasted 20 days in two nests, with the male spending more time (35–300 s, mean = 109 s) than the female taking care of the chicks (25–99 s, mean = 53 s). Reciprocal escorting was observed during the nestling phase, with the male always arriving first. Breeding occurred in January, April, May (two nests), June, and July. Observing the male of the Elegant Euphonia escorting the female during the incubation period, corroborates previous observations of this behavior in genera Euphonia and Chlorophonia. Incubation and nestling time periods were similar to other species of these genera.

The main problem of the theory in the arena of islamic architecture is affected by some of its Western<br />thoughts, and stereotyping the islamic architecture according to Western thoughts; this leads to the breakdown<br />of the foundations in the islamic architecture. It is a myth that islamic architecture is subjected to the<br />influence from foreign architectures. This paper will highlight the dialectical concept of islamic architecture or<br />muslim buildings and the areas of recognition in islamic architecture. It will also widen the knowledge in the<br />characteristics of each point in time according to the stages of islamic architecture from the prophetic age<br />moving through the architecture outside the city of Medina, the Caliphs, the Umayyad, Abbasid, and<br />architectural models by spatial and time periods, taking Iraq as the example to explain how the Islam influents<br />on architecture and vice versa.


The article is devoted to the study of the relationship between cultural landscape and architecture. The article considers the development of the city of Almaty since its Foundation as city in the context of relations between architecture and cultural landscape. The master plan is considered in different time periods, issues and problems of modern urbanisation of the city are identified, including the problem of taking into account regional identity in territorial planning.

This essay facilitates a multi-dimensional immersion into the life and rhythms of New Orleans, an entrée to the past that equips us to better understand the present and, from there, critically and creatively to envision our possible futures together. We explore the Faubourg Tremé by traversing layers of its lieux de souvenir - places of remembering, a concept inspired by but distinct from Pierre Nora’s lieux de mémoire - across three time periods. Each lieu de souvenir we visit from 1720 to the present will highlight material and symbolic foundations in Tremé that help us to understand key aspects of New Orleans’s past and present. The object that will guide our travel and meditation through each layer is the lowly but highly serviceable brick. At a purely material level, bricks are the literal building blocks of the city. Roads were paved with them and homes and other buildings were constructed with bricks as well. And at a symbolic level, bricks carry multiple rich and complex significations: Who makes them? How does their manufacturing shape the lives of the laborers who create them? Who buys them, and who profits from their sale? Tracing the brick and its uses throughout each lieu de souvenir sheds light on key social relationships, inequalities, and cultural practices that form the foundation of New Orleans’s past and present.

AbstractDetailed studies on the immature stages of the sorghum head bugs, Eurystylus immaculatus Odhiambo and Creontiades pallidus Rambur, were carried out in the laboratory at Samanko, Mali, during November 1991 to March 1992, and January to April 1993, and in the field in October 1993. Eggs of both species were laid in maturing sorghum (Sorghum bicolor) grains. The egg incubation period was 4–7 days in E. immaculatus, and 5–7 days in C. pallidus. There were five nymphal instars in both species. The total nymphal period was 6–11 days in E. immaculatus and 8–14 days in C. pallidus. The durations of first, second, third, fourth and fifth nymphal instars were 1–3, 1–2, 1–2, 1–3 and 1–3 days, respectively, in E. immaculatus, and 1–3, 1–2, 1–3, 2–3 and 2–4 days, respectively, in C. pallidus. All the immature stages of E. immaculatus are described and sketched.

This article is a study of developments in classical music criticism at the Toronto-based Globe and Mail newspaper from its inception in 1936 to the year 2000. Three distinct time-periods are identified, according to content, style and ideology: 1936-1952, a period of boosterism, when critics often saw it as their role to support Toronto's musicians and musical institutions; 1952-1987, when (during the lengthy tenure of critic John Kraglund) the newspaper took a more detached, non-partisan stance towards musicians and musical activities in the city; and 1987-2000, when critics began to address social, political, and economic issues governing classical music, and to question inherited cultural assumptions about the art form.

BACKGROUNDThe outbreak of the new coronavirus infection in Wuhan City, Hubei Province in December 2019, poses a huge threat to China and even global public health security. Respiratory droplets and contact transmission are the main routes of transmission of new coronaviruses. Compared with SARS and Ebola viruses, new coronavirus infections are infectious during the incubation period. Traditional SEIR (susceptibility-exposure-infection-Removal) There are some differences in conditions for the prediction of the epidemic trend of new coronavirus infection. The outbreak of the new coronavirus infection coincided with the Spring Festival before and after the Chinese Spring Festival.It is necessary to make appropriate optimization and amendments to the traditional model to meet the actual evolution of the epidemic situation.METHODSThe traditional SEIR model assumes that the virus-infected person is not infectious during the incubation period and that the infected person did not take isolation measures during the illness. The transmission of the new coronavirus no longer meets the basic assumptions of the classical kinetic system. Therefore, this article first establishes a modified SEIR model. Predict and analyze the changing trend of the epidemic situation, then estimate the parameters involved in the infection dynamics model, and then use Matlab to simulate the established dynamic equations based on public data and analyze the results. Recommendations for universal prevention and control of infectious diseases.RESULTSThe first case of new coronavirus infection was confirmed in Wuhan on December 8, 2019. When Wuhan City took no action, assuming the average daily number of contacts per infected person k = 5, the number of infected persons will reach about 2,384,803 people; If wuhan adopts the measures of sealing the city on January 22, 2020, under the premise of k=2, the number of infected people decreases by 19,773 compared with that on January 23, and there is no significant change in the time when the number of infected people reaches the peak. Under the premise of k = 1, the number of infected persons was reduced by 14,330 compared with the closure on January 23, and the time to reach the peak of the number of infected persons was reduced by 2 days. If Wuhan City is closed for one day, the number of infected persons will increase from 106,145 to 130,626 under the premise of k = 2; the number of infected persons will increase from 74,369 to 92,010 under the premise of k = 1.CONCLUSIONSComparing the number of confirmed diagnoses actually notified by the department with the number of infected people obtained from the simulation of the model, it can be seen that the city closure measures adopted by the Wuhan Municipal Government on January 23 and the first-level response measures adopted by the country are effective for the epidemic Prevention and control play a vital role. Wearing a mask when going out and avoiding close contact with people can effectively reduce the infection rate.
