Learning from biophysical heterogeneity: inductive use of case studies for maize cropping systems in Central America
No full textGlobal society has become conscious that efforts towards securing food production will only be successful if agricultural production increases are obtained through mechanisms that ensure active regeneration of the natural resource base. Production options should be targeted in the sense of that their suitability to improve agricultural production and maintain natural resources is evaluated prior to their introduction. Biophysical targeting evaluates production options as a function of the spatial and temporal variability of climate conditions, in interaction with soil, crop characteristics and agronomic management strategies. This thesis contributes to the development of a system-based methodology for biophysical targeting. Cropping system simulation and weather generator tools are interfaced to geographical information systems. Inductive use of two case studies - a green manure cover crop and reduced tillage with residue management - helped to develop the methodology. Insight is gained into the regional potential for and the soil and climate conditions under which successful introduction of these production options may be achieved. The resulting information supports regional stakeholders involved in agriculture in their analysis and discussion, negotiation and decision-making concerning where to implement production systems. This process can improve the supply of appropriate agricultural production practices that enhance production and conserve soil and water resources

Aim: to improve the outcomes of pregnancy complicated with preterm prelabour rupture of membranes (PPROM) occured between 22 and 34 weeks’ gestation by prescribing antibiotics which are highly effective against the most common microbes in these women.
Patients and Methods: clinical laboratory tests were performed in 60 pregnant women with PPROM occured between 22 and 33 + 6 weeks’ gestation. At admission, uterine secretion analysis and disc diffusion antibiotic susceptibility test were performed in a total of 60 women. Uterine secretion was introduced into the culture medium (blood agar 5% and Sabouraud dextrose agar). Microbial cultures were isolated and identified using standard methods.
Results: in most cases of PPROM, high levels of bacterial contamination of uterine cavity with various microbial associations in high titers (≥105 CFU/ml) were revealed. Among them, the most common bacteria were Enterococcaceae and Enterobacteriaceae spp. Enterococcus faecalis and E. faecium were identified in 83% of uterine secretions, Escherichia coli and Klebsiella pneumoniae were common as well while Staphylococcus aureus and S. epidermidis, Streptococcus agalactiae and Str. bovis, Burkholderia cepacia, Еnterobacter cloacae, Candida spp. were uncommon. Antibiotic susceptibility test has demonstrated that third-generation cephalosporins (cefotaxime and ceftazidime but not ceftriaxone) are highly effective against the most common isolated microbes. Moreover, these antibiotics are approved for their use in the second and third trimesters of pregnancy.
Conclusion: our findings demonstrate that cefotaxime is the first choice for empirical antibacterial treatment for PPROM occured between
22 and 34 weeks’ gestation. Regimens of initial antibacterial preventive treatment for PPROM which were developed on the basis of antibiotic susceptibility test results improve pregnancy outcomes regardless of delivery method.
Keywords: preterm prelabour rupture of membranes, preterm birth, antibacterial preventive treatment, antibiotic susceptibility.

No full textOn the separation of coconuts: a modeling week study
No full textThe modus operandi of "modeling weeks" is explained and illustrated using a classical modeling week problem of subjecting coconuts to an external pressure before splitting them open, in the hope that the coconut meat will then separate easily from the shell. A range of modeling approaches is considered, and a poroelastic model is posed that allows the key problem parameters to be identified and calculated. We conclude that separation by this means is likely to be possible and relatively easy to accomplish
Invitation to David Bishop from the Order of United Americans for a celebration of George Washington's birthday, February 1858
No full textThe Order of United Americans, also known as the Know-Nothings, formed in the mid-1800s to support the rights of native-born Americans over those of immigrants, and to combat what they saw as foreign influences on America. This letter is an invitation to Order member David Bishop, to a celebration in honor of George Washington's birthday. Page 1 shows the actual letter, and page 2 is the transcripts of the letter
Sarmatian Attributes in Archaeological Complexes of Catacombs Burials in Arys Culture of Southern Kazakhstan (1st Century B.C. - 3rd Century A.D.)
No full textThe publication is devoted to archaeological research of monuments of the catacomb of Arys culture of Southern Kazakhstan (1st Century B.C. - 3rd Century A.D.).
Now scientists have a complete understanding of the range and typology, periodization and chronology of monuments of this culture. There are three stages: Karaultobe (4th century B.C. - 1st century A.D.); Karatobe (1st Century B.C. - 4th century A.D.); Altintobe (4th-6th centuries A.D.). These stages are characterized by specific clusters of signs in the form of artifacts. The author also carried out the ethnic attribution of the Arys culture in association with the ancient state Kangiuj. As a result of this work, the ethnicity of the state Kangiuj was revealed: in particular, late Saka’s, Sarmatian, Huns and Kangiuj ethnic components which are relevant to archaeological complexes, were identified.
In the Arys monuments of culture the author discovered complexes of findings which associated with the Sarmatian world of Eurasia by their ethno-cultural parameters.
They include typical for the Sarmatians list of ritual action and the funerary equipment, including weapons, bronze mirrors, ritual and religious objects, signs-tamgas, jewelry (including Egyptian faience), articles in “animal”, gold-turquoise and polychrome style.
The characteristics of the burial complexes of catacombs of the Arys culture discussed in the publication and corresponding to chronological calculations and ethno-cultural interpretations, allow to speak about presence in the territory of South Kazakhstan of the Asian Sarmatians or any local branch of the Union of the Sarmatian tribes in the 1st century B.C. - 3rd century A.D
