    Forty-two years ago, Capra published “The Tao of Physics” (Capra, 1975). In this book (page 17) he writes: “The exploration of the atomic and subatomic world in the twentieth century has …. necessitated a radical revision of many of our basic concepts” and that, unlike ‘classical’ physics, the sub-atomic and quantum “modern physics” shows resonances with Eastern thoughts and “leads us to a view of the world which is very similar to the views held by mystics of all ages and traditions.“ This article stresses an analogous situation in biology with respect to a new theoretical approach for studying living systems, Integral Biomathics (IB), which also exhibits some resonances with Eastern thought. Stepping on earlier research in cybernetics1 and theoretical biology,2 IB has been developed since 2011 by over 100 scientists from a number of disciplines who have been exploring a substantial set of theoretical frameworks. From that effort, the need for a robust core model utilizing advanced mathematics and computation adequate for understanding the behavior of organisms as dynamic wholes was identified. At this end, the authors of this article have proposed WLIMES (Ehresmann and Simeonov, 2012), a formal theory for modeling living systems integrating both the Memory Evolutive Systems (Ehresmann and Vanbremeersch, 2007) and the Wandering Logic Intelligence (Simeonov, 2002b). Its principles will be recalled here with respect to their resonances to Eastern thought

    The amount and quality of station climate data has been declining all over Africa. Despite a noteworthy legacy in the provision of agro-meteorological extension to farmers (Mason, 2015; Dinku, 2016) , the large landlocked country of Mali is no exception: there, a security crisis in the northern half of the country since 2012 has further aggravated the provision of data from an already sparse weather station network. This greatly hinders local decision-making processes that may benefit from the use of climate data, and affects the ability of vulnerable communities to sustain their resilience capacity in a changing environment characterized by population growth, increasing externalization of risk and expected rise in the frequency of extreme events. Restoring the availability and accessibility of quality climate data over space and time is the aim of the ENACTS (Enhancing National Climate Services) initiative, promoted by the International Research Institute for Climate and Society (IRI, at Columbia University). On November 3, 2016, ICRISAT, Mali-Meteo and IRI launched the ENACTS initiative in Mali during a national workshop to i) introduce stakeholders to Mali Meteo’s new data and web interface (Mali Meteo Data Library) and; ii) solicit feedbacks and recommendations from the national community of users. This workshop was a result of collaboration between the CCAFS-funded CASCAID project (Capacitating African Smallholder with Climate Services and Insurance Development) led by ICRISAT and ICRAF, and the USAID-funded project Building Mali Meteo’s Capacity to Deliver Improved Climate Services, led by IRI. During the workshop, participants showed high interest in the new tools and requested additional capacitation through a dedicated follow-up event targeting sectorial applications of the data library and maprooms

    Background: Intra-abdominal infections (IAIs) have different aspects to consider. One important aspectis the microbiological analyses, especially in the era of broad spread of resistant microorganisms. The studywas designed to describe the clinical characteristics and microbiological profiles of community acquired IAIs. Method: An observational study was performed on medical records of 12 months period (January toDecember 2013) in a General Hospital, Karawaci, Tangerang. Adult patients undergoing surgery for IAIs with positive microbiological culture and identification of microorganisms were included. Data collected were clinical characteristics and microbiological profiles and wereanalyzed statisticallyusing the SPSS version 17. Results: In 12 months period of study, 17 patients of IAIs with a total of 17 intra peritoneal specimens were collected. A total of six microorganisms were cultured. All the IAIs were monomicrobial, with aerobicmicroorganism dominantly Gram-negative bacilli. The dominant microorganism was Escherichia coli (E.coli), found in 58.8% of IAIs. The most common site was appendix (41.2%), and none from small intestine. Thesusceptibility test found that piperacillin tazobactam, tigecycline, meropenem and amikacin were the most activeantimicrobial against E. coli. Multi-drug resistant (MDR) E. coli in this study was 40%. The MDR E. coli had66.6% resistance to levofloxacin and ciprofloxacin, 66.6% susceptibility to ceftriaxone and ceftazidime, and100.0% susceptibility to amikacin. Conclusion: The most common site of community-acquired IAIs was appendix (41.2%). E. coli is still adominant microorganism with the MDR E. coli proportion of 40%

    The aim of this work was to formulate and optimize the washing performance of an alkylpolyglucoside-based dishwashing detergent. The liquid detergent was formulated with five ingredients of commercial origin: anionic (linear sodium alkylbenzenesulfonate and sodium laurylethersulfate), nonionic (C12–C14 alkylpolyglucoside) and zwitterionic (a fatty acid amide derivative with a betaine structure) surfactants, and NaCl for viscosity control. In addition to the plate test, other properties were investigated including ‘‘cloud point’’, viscosity, and emulsion stability. Statistical analysis software was used to generate a central composite experimental design. Then, a second order design and analysis of experiments approach, known as the Response Surface Methodology, was set up to investigate the effects of the five components of the formulation on the studied properties in the region covering plausible component ranges. The method proved to be efficient for locating the domains of concentrations where the desired properties were met

    Standard methods for Apis mellifera anatomy and dissection

    An understanding of the anatomy and functions of internal and external structures is fundamental to many studies on the honey bee Apis mellifera. Similarly, proficiency in dissection techniques is vital for many more complex procedures. In this paper, which is a prelude to the other papers of the COLOSS BEEBOOK, we outline basic honey bee anatomy and basic dissection techniques

    Headache yesterday in Europe

    BACKGROUND: Surveys enquiring about burden of headache over a prior period of time (eg, 3 months) are subject to recall bias. To eliminate this as far as possible, we focused on presence and impact of headache on the preceding day (“headache yesterday”). METHODS: Adults (18-65 years) were surveyed from the general populations of Germany, Italy, Lithuania, Luxembourg and the Netherlands, from a work-force population in Spain and from mostly non-headache patient populations of Austria, France and UK. A study of non-responders in some countries allowed detection of potential participation bias where initial participation rates were low. RESULTS: Participation rates varied between 11% and 59% (mean 27%). Non-responder studies suggested that, because of participation bias, headache prevalence might be overestimated in initial responders by up to 2% (absolute). Across all countries, 1,422 of 8,271 participants (15-17%, depending on correction for participation bias) had headache yesterday lasting on average for 6 hours. It was bad or very bad in 56% of cases and caused absence from work or school in 6%. Among those who worked despite headache, 20% reported productivity reduced by >50%. Social activities were lost by 24%. Women (21%) were more likely than men (12%) to have headache yesterday, but impact was similar in the two genders. CONCLUSIONS: With recall biases avoided, our findings indicate that headache costs at least 0.7% of working capacity in Europe. This calculation takes into account that most of those who missed work could make up for this later, which, however, means that leisure and social activities are even more influenced by headache

    Regularly arranged indium islands on glass/molybdenum substrates upon femtosecond laser and physical vapor deposition processing

    Get PDF
    A bottom-up approach is presented for the production of arrays of indium islands on a molybdenum layer on glass, which can serve as micro-sized precursors for indium compounds such as copper-indium-gallium-diselenide used in photovoltaics. Femtosecond laser ablation of glass and a subsequent deposition of a molybdenumfilm or direct laser processing of the molybdenumfilm both allow the preferential nucleation and growth of indium islands at the predefined locations in a following indium-based physical vapor deposition(PVD) process. A proper choice of laser and deposition parameters ensures the controlled growth of indium islands exclusively at the laser ablated spots. Based on a statistical analysis, these results are compared to the non-structured molybdenumsurface, leading to randomly grown indium islands after PVD
