NEW AMS 14C DATES OF A MULTICULTURAL ARCHAEOLOGICAL SITE FROM THE PALEO-DELTAIC REGION OF WEST BENGAL, INDIA: CULTURAL AND GEO-ARCHAEOLOGICAL IMPLICATIONS

ABSTRACT This study is on the absolute age dating of a multicultural site of Erenda, East Medinipur district, in coastal West Bengal, India. Charcoal samples were collected and measured using the accelerator mass spectrometry (AMS) facility at the Inter-University Accelerator Centre, New Delhi, India. These samples were collected from secured stratigraphic context of two excavated trenches. A careful collection of samples from two trenches provided us with the first calendar dates, 950 BCE and 1979 BCE, of protohistoric sites in coastal West Bengal. These calibrated calendar dates not only have wider significance in terms of archaeology but also methodological implications to understand the relevance of application of AMS from the dynamic coastal landscape in the humid tropics during the late Holocene period.

Characteristics of Iris pumila and standard and miniature dwarf bearded irises in the collection of the Education and Research Center “Botanical Garden” of Saratov State University

The article presents the results of the study of phenoritmes and introductional evaluation of dwarf irisand its grade forms. During the phenological observations between 2016 and 2020, the Education and Research Center“Botanical Garden” in Saratov established calendar dates of the main development phases, determined the average datesand duration of flowering in the studied samples. The revision showed that the studied species and varieties are stable inthe culture in the Lower Volga region, as they are winter-resistant, immune to diseases and pests, are distinguished by thedecorative flowering. The varieties of toffee are low for a number of observed years successfully grow, preserving theirvarietal characteristics. Assessment of the introduction success showed that the studied species and varieties of iris werepromising for introduction into the culture and can be recommended for landscaping in the conditions of Saratov.

PERUMUSAN KALENDER SYAMSI HIJRI IRAN DAN AHMADIYAH DALAM TINJAUAN AL-SIYASAH AL-SYAR’IYYAH

Calendar had a function as a regulator of community activities, both civil and religious activities. The Islamic calendar which whom established by Prophet Muhammad by adopting Lunar system also had a civil function. The Islamic calendar also had a major element to prescribe the timing of worships such as the time of fasting and Hajj. The Shamsi Hijri Calendar of Iran and the Ahmadiyya Community were calendars based on solar system which the beginning of the year starts from the Hijrah of Prophet Muhammad. The Iranian calendar dates back to ancient Persian times while the Ahmadiyya calendar is an adoption of the Gregorian calendar labeled by the symbols of Islam. Viewed from the perspective of Siyasah Shar'iyyah, the two calendars designed so each of community gets maslahat according to paradigm of each authorities. The Iranian Hijri Shamsi Calendar designed for the Iranians to keep their identity as Persians as well as to show their Islamic identity and shiáh characteristics. The Ahmadiyya calendar designed as an effort to Islamize the Gregorian calendar aside from an effort to internationalize this Jamaah and also as a symbol of relationship between Mirza Ghulam Ahmad, the founder of Ahmadiyya and Prophet Jesus Christ since Mirza Ghulam Ahmad also pronounced as Messiah as what it seems in Prophet Jesus. In the framework of al-siyasah al-Shar'yyah, the Iranian Hijri Shamsi calendar design is not as problematic as this calendar for religious purposes nor to the Ahmadiyya calendar, as both calendars were nothing more than a civil calendars.

Calendar and Dates in Jubilees’ Garden of Eden Story

Calendar dates in Jubilees’ Garden of Eden story have led some to question the nature of the book’s presupposed calendar and others to conclude that the passage is redacted. Close reading of the text shows that the passage was carefully constructed and the work of one author who took pains not to jeopardize the calendar promoted elsewhere in the book. Confusion arises when scholars subordinate the calendar to the book’s chronological system; they should be kept distinct. The author uses the recurrence of calendar dates to connect events to each other typologically and to an underlying narrative pattern, which, like the calendar, is founded on the annual cycle of agricultural labor.

COVID-19 epidemic scenarios into 2021 based on observed key superdispersion events

Key high transmission dates for the year 2020 are used to create scenarios to model the evolution of the COVID-19 pandemic in several states of Mexico for 2021. These scenarios are obtained through the estimation of a time-dependent contact rate, where the main assumption is that the dynamic of the disease is heavily determined by the mobility and social activity of the population during holidays and other important calendar dates. First, changes in the effective contact rate on predetermined dates of 2020 are estimated. Then, using the instantaneous reproduction number to characterize the status of the epidemic (Rt ≈ 1, Rt > 1 or Rt < 1), this information is used to propose different scenarios for the number of cases and deaths for 2021. The main assumption is that the effective contact rate during 2021 will maintain a similar trend to that observed during 2020 on key calendar dates. All other conditions are assumed to remain constant in the time scale of the projections. The objective is to generate a range of scenarios that could be useful to evaluate the possible evolution of the epidemic and its likely impact on incidence and mortality.

On the problem of interrelation between extreme lunisolar tides in 2021 and weather change

The transformations of synoptic processes and severe weather events that sometimes accompany them occur near the extremes (maxima and minima) of tidal fluctuations in the Earth’s angular velocity. A graph of tidal fluctuations in the Earth’s angular velocity for 2021 is presented. The extremes of tidal fluctuations in the Earth’s angular velocity for 2021 are identified and their calendar dates are determined. On these dates, the transformation of synoptic processes and sometimes hydrometeorological hazards may be expected. The case of catastrophic icing in the Vladivostok area during the extreme on November 18, 2020 is described. Keywords: transformation of synoptic processes, weather forecasts, severe weather events, tidal fluctuations in the Earth’s angular velocity
