An old horse revived? In-house use of print books at Seton Hall University.

With limited library budgets and declining circulation of print books, it is important to demonstrate library value to multiple stakeholders and to make informed collection development choices. The aim of this one-year study was to gain a complete picture of print book circulation by identifying titles that were used in the library (‘in-house’) but not checked out. We found that almost 30% of circulation transactions were books that were used in-house. Medical and nursing books showed the highest rate of in-house use in both the reference and main (circulating) collection. A close examination of these subject areas indicated that 46% of potentially circulating medical books used in-house were checked out, and 19% of science books used in house were checked out. This suggests that libraries should not assume that titles used in-house are subsequently checked out, or that check out statistics represent the totality of book use. We recommend including in-house use statistics to obtain an accurate picture of total circulation and library value, and to inform collection development

Screening of a HUVEC cDNA library with transplant-associated coronary artery disease sera identifies RPL7 as a candidate autoantigen associated with this disease.

A HUVEC cDNA library was screened with sera from two patients who had developed transplant-associated coronary artery disease (TxCAD) following cardiac transplantation. A total of six positive clones were isolated from a primary screen of 40 000 genes. Subsequent DNA sequence analysis identified these to be lysyl tRNA synthetase, ribosomal protein L7, ribosomal protein L9, beta transducin and TANK. Another gene whose product could not be identified showed homology to a human cDNA clone (DKFZp566M063) derived from fetal kidney. Full-length constructs of selected genes were expressed as his-tag recombinant fusion proteins and used to screen a wider patient base by ELISA to determine prevalence and association with TxCAD. Of these ribosomal protein L7 showed the highest prevalence (55.6%) with TxCAD sera compared to 10% non-CAD

A Paradox Within The Time Value Of Money: A Critical Thinking Exercise For Finance Students

This study presents a paradox within the time value of money (TVM), namely, that the interest-principal sequence embedded in the payment stream of an amortized loan is exactly the opposite of the interest-principal sequence implicit in the present value of a matching annuity.  We examine this inverse sequence, both mathematically and intuitively, and argue that it provides an excellent exercise for finance students to explore, both to enhance their critical thinking skills as well as to strengthen their understanding of TVM concepts.  Additionally, such an exercise will involve them actively in the learning process, as mandated by AACSB International’s Eligibility Procedures and Standards for Business Accreditation

TERPENES PROPERTIES AS BIOPESTICIDES

Biopesticide consists of many different types like plants, fungi, bacteria, microalgae and nowadays it is not yet widely introduced and rarely available in the market; common available pesticides are chemical-based pesticides that harm not only the environment but also humans. Plant essential oils are created from different plant resources, most of them are members of the mint family (Lamiaceae) and a multiple combination of a class of terpenes that consist of two-isoprene units or called monoterpenes composed of oils. It linked an aromatic compound with a molecular formula of C6H5OH or called phenols and a sesquiterpenes. Further research is needed in the emerging or happening of organic pesticides with showing the possible control agents, formulation, delivery and commercialization. Since the availability of biopesticides are minimal, the researchers come up with the idea of synthesizing a prototype of biopesticides from lemon peel, neem leaves, cinnamon bark and garlic using steam distillation as a mode of extraction of the essential property which is terpenes that holds a promising role in killing pest particularly aphids. The findings of this study aim to test the efficacy of the prototype made by the researchers which is the biopesticides that has extracts from lemon peel, neem leaves, garlic and cinnamon bark. The researchers are recommending the application of the prototype to the other pests and insects in order to know the effectiveness of it besides aphids

Magnetoencephalographic Signals Identify Stages in Real-Life Decision Processes

We used magnetoencephalography (MEG) to study the dynamics of neural responses in eight subjects engaged in shopping for day-to-day items from supermarket shelves. This behavior not only has personal and economic importance but also provides an example of an experience that is both personal and shared between individuals. The shopping experience enables the exploration of neural mechanisms underlying choice based on complex memories. Choosing among different brands of closely related products activated a robust sequence of signals within the first second after the presentation of the choice images. This sequence engaged first the visual cortex (80-100 ms), then as the images were analyzed, predominantly the left temporal regions (310-340 ms). At longer latency, characteristic neural activetion was found in motor speech areas (500-520 ms) for images requiring low salience choices with respect to previous (brand) memory, and in right parietal cortex for high salience choices (850-920 ms). We argue that the neural processes associated with the particular brand-choice stimulus can be separated into identifiable stages through observation of MEG responses and knowledge of functional anatomy

Nicaragua Block Press

Friends In Action International (FIA), our project partner, is assisting the Rama people of Nicaragua in relocating from an overpopulated island to the mainland. Our team has developed a manual press for the Rama people to produce compressed earth blocks from local materials for construction of their homes. After testing an initial prototype of the press in Nicaragua it was determined that the press needed more durability. After testing two presses with welded chambers manufactured by E&E Metal Fab Inc., further modifications were required such as welding chamber skirts, adding a lid handle, and applying rust prevention coating. Once both presses reached a workable state, the team made blocks using different mixtures to determine the composition for the highest strength. Blocks were tested for water absorption and for strength in compression, and met published standards for compressed earth blocks (CEB). The team also developed a user manual complete with manufacturing instructions, operating procedures, maintenance suggestions, and exploded subassembly views. Lastly, our team has drafted a one-page user guide for quick reference on-site and will deliver everything to FIA at the end of the semester.https://mosaic.messiah.edu/engr2020/1002/thumbnail.jp

Maximum Power Efficiency and Criticality in Random Boolean Networks

Random Boolean networks are models of disordered causal systems that can occur in cells and the biosphere. These are open thermodynamic systems exhibiting a flow of energy that is dissipated at a finite rate. Life does work to acquire more energy, then uses the available energy it has gained to perform more work. It is plausible that natural selection has optimized many biological systems for power efficiency: useful power generated per unit fuel. In this letter we begin to investigate these questions for random Boolean networks using Landauer's erasure principle, which defines a minimum entropy cost for bit erasure. We show that critical Boolean networks maximize available power efficiency, which requires that the system have a finite displacement from equilibrium. Our initial results may extend to more realistic models for cells and ecosystems.Comment: 4 pages RevTeX, 1 figure in .eps format.

239. Ocena efektu przeciwnowotworowego genetycznie modyfikowanej szczepionki komórkowej w mysim modelu raka nerki

CelGenetycznie modyfikowane szczepionki komórkowe (GMTV) mają za zadanie indukcję efektywnej odpowiedzi przeciwnowotworowej. Postanowiliśmy ocenić efekt protekcyjny dwóch różnych GMTV w mysim modelu raka jasnokomórkowego nerki, oraz rolę komórek dendrytycznych w fazie indukcji przeciwnowotworowej odpowiedzi komórkowej.MetodyPrzy wykorzystaniu wektorów retrowirusowych DCCMV-IRES-Neo-H-6 oraz DCCMV-IRES-Neo-IL-6 wprowadzono do komórek mysiego raka jasnokomórkowego (RenCa) skonstruowano dwa rodzaje GMTV: (i) Komórki RenCa wykazujące ekspresję genu Interleukiny-6, (ii) komórki RenCa wykazujące ekspresję genu Hyper-lnterleukiny-6 (sztuczna cytokina będąca białkiem fuzyjnym składającym się z IL-6 powiązanej sztucznym linkerem z agonistycznym rozpuszczalnym receptorem) W celu oceny efektu protekcyjnego GMTV, myszy Balb/c w wieku 8–12 tygodni (8 osobników w jednej grupie eksperymentalnej) immunizowano podając podskórnie w lewe udo, 1×10^6 naświetlonych (80 Gy) komórek (RenCa w/t, RenCa-IL-6, Renca-H6). Po 14 dniach myszom podawano podskórnie w prawe udo wyjściowe komórki RenCa w/t w ilości 5×10^5. Następnie oceniano dynamikę pojawiania się guzów oraz kinetykę ich wzrostu. W celu oceny mechanizmów indukcji odpowiedzi immunologicznej postanowiono ocenić in situ wpływ poszczególnych rodzajów GMTV na komórki dendrytyczne. Myszy Balb/c otrzymywały w okolicy śródbrzusza, podskórnie 2×10^6 napromienionych (80 Gy) komórek Renca w/t, Renca-IL-6, Renca H-6 zawieszonych w Matrigelu™. Po 7 dniach przy pomocy cytometru przepływowego analizowano komórki naciekające Matrigel.Wyniki i podsumowanieImmunizacja myszy komórkami RenCa-H6 okazała się najbardziej efektywna w porównaniu do komórek RenCa w/t i RenCa-IL-6. Jakkolwiek nie przeciwdziałała wzrostowi guzów. Aktywowane komórki DC naciekały najsilniej komórki RenCa-H6. Efekt protekcyjny wyraźnie korelował z ilością aktywowanych komórek DC naciekających miejsce podania GMTV. Intensywna infiltracja miejsca podania GMTV przez komórki DC o wysokim poziomie aktywacji wskazuje na silną role Hyper-Interleukiny-6 w procesie indukcji funkcjonalnej przeciwnowotworowej odpowiedzi immunologicznej
