This paper addresses the strategies adopted by science-based start-ups to gain access to knowledge resources at different spatial levels. The goal of the paper is to investigate the presence and relative importance of ties endowed with different types of proximity in firms’ knowledge networks, as well as the role played by non-geographical proximity in gaining access to knowledge sources, both ...

The International Crops Research Institute for the Semi-Arid Tropics conserves 335 accessions of Pennisetum glaucum subsp. monodii originated in 13 countries. In the present study, the collection was evaluated and assessed for diversity and geographical gaps. A wide variation was observed in the collection for total tillers per plant (16 to 609), productive tillers per plant (12 to 368), leaf l...

Chlamydia pneumoniae is a common human and animal pathogen associated with a wide range of diseases. Since the first isolation of C. pneumoniae TWAR in 1965, all human isolates have been essentially clonal, providing little evolutionary insight. To address this gap, we investigated the genetic diversity of 30 isolates from diverse geographical locations, from both human and animal origin (amphi...

Honey authenticity is defined by the Codex Alimentarius standard, the EU Honey Directive and several national legislations. The Codex and EU standards were recently revised. The authenticity of honey and other bee products have two aspects. Authenticity in respect of production i.e. to prevent adulteration by addition of other food ingredients by correct beekeeping practice and processing. The ...

Knowing the geographical origin of economically important plants is important for genetic improvement and conservation, but has been slowed by uneven geographical sampling where relatives occur in remote areas of difficult access. Less biased species sampling can be achieved when herbarium collections are included as DNA sources. Here, we address the history of Cucurbitaceae, one of the most ec...

,~Rs~K:\ ( .T . Developn~ent of' a new turfgrass cultivar requires an evaluation of numerous traits as well as an understanding of environmental factors influencing those traits. Growth or ability to fill in gaps and time of fall dormancy (fall color retention) that indicates cold hardiness are important traits for turfgrasses. This study was initiated to characteri~e variation in saltgrass [IX...

Thermal Ionisation Mass Spectrometry (TIMS) was applied to discriminate a total of 118 tomato samples (berries, "passata", tinned tomatoes, sauce, double and triple concentrate) coming from two different countries. The TIMS technique gave significantly different results for the (87)Sr/(86)Sr ratios and δ‰ values between Chinese and Italian tomato samples, irrespective of the treatment type. Thi...

Radix Pseudostellariae is one of the most popular Traditional Chinese Medicine (TCM) for promoting the immune system, treating asthenia after illnesses with a long history in China and some other Asian countries. Rapid discrimination of R. Pseudostellariae according to geographical origin is crucial to pharmacodynamic action control. FT-NIR spectroscopy and supervised pattern recognition was at...

Many endemic species present disjunct geographical distribution; therefore, they are suitable models to test hypotheses about the ecological and evolutionary mechanisms involved in the origin of disjunct distributions in these habitats. We studied the genetic structure and phylogeography of Tibouchina papyrus (Melastomataceae), endemic to rocky savannas in Central Brazil, to test hypothesis of ...

Online dating sites have become popular platforms for people to look for potential romantic partners. It is important to understand users’ dating preferences in order to make better recommendations on potential dates. The message sending and replying actions of a user are strong indicators for what he/she is looking for in a potential date and reflect the user’s actual dating preferences. We st...
