Review of "System Modeling in Cellular Biology: From Concepts to Nuts and Bolts" by Szallasi, Stelling and Periwal

"System Modeling in Cellular Biology: From Concepts to Nuts and Bolts" by Szallasi, Stelling and Periwal introduces the relevant concepts, terminology, and techniques of this field of science. It emphasises the modelling and computational challenges of taking a multidisciplinary approach to biology. This book provides a comprehensive introduction to systems biology and will form a valuable resource for students, teachers and researchers from both experimental and theoretical disciplines

Benefits of Including SAE Bolts, Nuts, and Washers in the AISI STANDARD S100

The addition of SAE J429 bolts along with their associated nuts and washers into the AISI STANDARD S100, North American Specification for the Design of Cold-Formed Members, would be a significant enhancement to the specification by providing practitioners the opportunity to use a broader range of fasteners for the design of cold-formed steel structures. The design of bolted connections using SAE J429 bolts would be advantageous for many types of structures including mechanical support structures, storage rack systems, photovoltaic support structures, carport structures, and conventional repetitive frame structures that all utilize cold-formed steel members. These structures would benefit by having a more robust range of smaller diameter fasteners available that are not found in ASTM A307 common bolts or ASTM F3125 Grades A325 or A490 high-strength structural bolts. Many industries that require small diameter fasteners already use SAE J429 bolts or have attempted to use SAE bolts in their designs without any specification guidance. Incorporation of SAE J429 bolts into AISI STANDARD S100 requires a comparison between the ASTM bolts currently recognized in the Standard with those SAE bolts looking to be included in the specification. This comparison would need to cover: 1) Geometry of the bolt, nut, and washer,2) Bearing strength of connections,3) Shear strength of SAE bolts,4) Tension strength of SAE bolts, and5) Assurance of quality. This comparison would also need to demonstrate that SAE J429 bolted connections will provide designs with an equivalent level of safety or resistance as do ASTM bolts. The following sections address these issues and provide the reasons or benefits for their proposed inclusion in the next edition of the AISI Standard

Transcription

Transcription, the written representation of spoken human language, is vital to any language documentation and revitalization project. This hands-on workshop introduces participants to a variety of different transcription methodologies for various purposes. The workshop primarily focuses two types of transcription: (i) phonetic transcription using the International Phonetic Alphabet and (ii) discourse transcription where elements of well-known transcription systems are introduced (Conversation Analysis – developed at UC Santa Barbara). The workshop emphasizes the nuts and bolts of these transcription systems and how to apply transcription practices to documentation and revitalization projects.2015 NSF/BCS 1500841: CoLang 2016: Institute on Collaborative Language Research – ALASKA Alaska Native Language Cente

Payments for Environmental Services: Some Nuts and Bolts

Payments for environmental services (PES) are part of a new and more direct conservation paradigm, explicitly recognizing the need to bridge the interests of landowners and outsiders. Eloquent theoretical assessments have praised the absolute advantages of PES over traditional conservation approaches. Some pilot PES exist in the tropics, but many fi eld practitioners and prospective service buyers and sellers remain skeptical about the concept. This paper aims to help demystify PES for non-economists, starting with a simple and coherent defi nition of the term. It then provides practical 'how-to' hints for PES design. It considers the likely niche for PES in the portfolio of conservation approaches. This assessment is based on a literature review, combined with fi eld observations from research in Latin America and Asia. It concludes that service users will continue to drive PES, but their willingness to pay will only rise if schemes can demonstrate clear additionality vis-à-vis carefully established baselines, if trust-building processes with service providers are sustained, and PES recipients' livelihood dynamics is better understood. PES best suits intermediate and/or projected threat scenarios, often in marginal lands with moderate conservation opportunity costs. People facing credible but medium-sized environmental degradation are more likely to become PES recipients than those living in relative harmony with Nature. The choice between PES cash and in-kind payments is highly context-dependent. Poor PES recipients are likely to gain from participation, though their access might be constrained and non-participating landless poor could lose out. PES is a highly promising conservation approach that can benefi t buyers, sellers and improv
