Francis Bacon: Of Building, Essay 45, aus: Francis Bacon: The Essayes or Counsels, Civill and Morall, of Francis Lo. Verulam, Viscount St. Alban (London: Printed by Iohn Haviland for Hanna Barret, 1625) (FONTES 16)

Together with 'The Elements of Achitecture' by Henry Wotton (1624), Francis Bacon’s essay 'Of Building' (1625, no. 45) constitutes the earliest significant statement of architectural thought both in printed form and in English. With his opening sentence, “A house is to live in, and not to look on”, Bacon gives expression to a new functionalist and empiricist position that anticipates architectural theories of modern times. Bacon discusses the site of the house (“seat”), and he proposes a verbal model for a “princely palace”. This building is placed within a row of symmetrical courtyards and in a landscape garden. A glossary of technical and archaic terms and words is provided, in addition to: (1) a brief discussion of architectural publications in England before 1625, (2) a biography of Bacon, (3) a brief treatment of Bacon’s utopia, The New Atlantis (1627), (4) a summary bibliography of literature about Bacon and his writings. Full texts are provided of (1) Bacon’s dedication of his Essays in 1625 to the Duke of Buckingham, (2) Bacon’s essay, 'Of Plantations', (3) his essay, ‘Of Beauty’. (The essay, 'Of Gardens', will be the subject of a subsequent number of FONTES.) The full text of Bacon’s 'Of Building' is complemented by an index of ‘notable things’. An anthology of commentaries to Bacon’s 'Of Building' provides excerpts from the critical literature in English and German.

The role of dynamic capabilities in circular economy implementation and performance of companies

Abstract Although most companies perceive that they might not be able to implement a circular economy (CE), some scholars perceive that companies may do so by developing dynamic capabilities (DCs). To empirically investigate the role of DCs in CE implementation, we analyzed a sample of 220 companies in Italy through partial least squares structural equation modeling (PLS‐SEM). Our PLS‐SEM analysis demonstrates that DCs and their underlying organizational activities significantly facilitate CE implementation, which consequently improves the overall performance of companies. Moreover, a circular dynamic environment (CDE) may stimulate companies towards CE implementation. This paper contributes to the literature in the following manner. First, this paper highlights how companies can identify and pursue CE opportunities. Second, this paper contributes to the debate on the role of a dynamic environment and how DCs leads to performance. Third, this paper presents the measurement scales of DCs and shows how to operationalize a hierarchical component model (HCM) in PLS‐SEM.

Pradimicin therapy of disseminated Candida tropicalis infection in the mouse

BMS 181184 (BMS), an analogue of pradimicin, was administered intravenously to neutropenic mice infected with either a fluconazole-susceptible or a fluconazole-resistant clinical isolate of Candida tropicalis. BMS prolonged survival at doses >3 mg kg -1 day-1, and at higher doses reduced tissue counts in mice. BMS was less potent mg for mg than amphotericin B. Combined BMS and amphotericin B were no more effective than either of the individual drugs.

Integration of ethics in e-Learning through Virtual Academic Counsellor

It is vital for e-Learning stakeholders to overcome the factors which affect the students to deviate from educational objective. A Delphi study with the help of e-Learning experts was conducted to investigate and control this issue. Lack of face to face traditional interaction among students and teachers in e-Learning was observed the root cause of ethical dilemma. Moreover, deficiency of counseling and traditional policies in independent e-learning environment also become the cause of this ethical dilemma. Different approaches to control this issue were also discussed and investigated to propose a model. It is recommended to involve members of the society as virtual academic counsellor in e-Learning to develop ethical and moral values of students. The study fulfils an identified need that how ethics can be integrated in e-Learning management system of academic institution to produce ethically competent graduates. It is expected that by following provided guidelines, the passing graduates will have field specific knowledge along with good ethical building to serve not just their families and societies but the entire nation.

Virilizing doses of testosterone decrease circulating insulin levels and differentially regulate insulin signaling in liver and adipose tissue of females

Acute virilizing doses of testosterone administered to females suppress circulating insulin levels, upregulate components of the insulin-signaling pathway in liver, and suppress insulin signaling in white adipose tissue. These results suggest that insulin resistance in transgender men may be due to suppression of the insulin-signaling pathway and decreased insulin sensitivity in white adipose tissue.

Bird species identification based on timbre and pitch features

This study proposes an automatic bird sound identification system to help people learn to identify bird species. The system is built upon a two-stage identification framework. The first stage performs call/song classification. If an unknown sound clip is classified as a call, it is then handled by a call identifier in the second stage; otherwise, it is handled by a song identifier. Both identifiers use two acoustic features, timbre and pitch, to determine which of the bird species the sound clip belong to. In using timbre features, bird sounds are converted into MFCCs and their first derivatives and then analyzed using Gaussian mixture models. In using pitch feature, we convert bird sounds into MIDI note sequences and then use bigram models to analyze the dynamic change information of the notes. Our experiments, conducted using a database including twenty common bird species, show that the proposed system can achieve 90.4% accuracy.

Effects of Jack Pine Plantation Management on Barrens Flora and Potential Kirtland's Warbler Nest Habitat

Abstract Jack pine barrens, once common in northern lower Michigan, mostly have been converted to managed jack pine plantations. Management of the disturbances associated with logging provides the opportunity to maintain the unique plant assemblages of jack pine barrens and nest habitat of the federally endangered Kirtland's warbler. Studies indicate that Carex pensylvanica can develop into dense mats and strongly compete with other barrens species such as Vaccinium angustifolium , which seem to be important species for Kirtland's warbler nest locations. According to forest managers, the most important factors facilitating high cover of V. angustifolium and reducing cover of C. pensylvanica are the amount of shade produced by tree crowns before harvest (pre‐harvest shade), the length of time between harvest and planting (planting delay), and fire. We found that high or low levels of pre‐harvest shade had no effect on cover of either V . angustifolium or C. pensylvanica . Planting delays of at least three years following prescribed burns generally increased cover of V. angustifolium in forest plots, which are important for warbler nesting. Analysis of community composition in openings indicated that burning enhanced the growth of barrens species. We found only weak evidence for a negative correlation between the cover of V. angustifolium and C. pensylvanica on our study sites. The openings created in the jack pine plantation are important refugia for barrens flora that would likely be lost under forests managed strictly for jack pine. Maintenance of jack pine barrens flora and Kirtland's warbler nest habitat is possible within the context of a heavily managed forest plantation system.

Recovering the lost gold of the developing world: case study in Migori County, Kenya

Artisanal & Small-scale Gold Mining (ASGM) is a subsistence level livelihood for many rural communities across the world. In Kenya it provides work for an estimated 40,000 people and produces 5 Tonnes of gold per year. The impact of ASGM is double-edged with the economic benefits offset by damage to the environment and the health of the mining communities due to the widespread use of mercury to recover gold. As a signatory to the Minamata Convention on Mercury (2017), Kenya has agreed to eliminate the use of mercury, formalise the ASGM sector,introduce good practice and protect the health of mining communities. Migori County is a major ASGM centre in southwest Kenya where gold is produced from quartz–carbonate reefs in the Migori greenstone belt. Recovery of gold involves extraction of the ore by mining and processing. The deep mine shafts are unstable and there are regular reports of fatalities due to mine collapse. The gold is recovered by manual crushing, ball milling, sluice box concentration and mercury amalgamation. Residual gold is recovered by cyanidation of the tailings. The local ASGM communities are concerned about the safety of the mining, the environmental impact of mercury and poor gold recovery. The British Geological Survey (BGS) worked with the University of Nairobi and the Migori County Artisanal Miners Co-operative (MICA) to promote good ASGM practice, reduce mercury use and improve gold recovery using appropriate technology. On average hard rock gold is finer than 100 microns. This makes the use of a sluice box a very inefficient recovery method with expected recoveries as low as 20% for gold of 100 microns or finer. This paper outlines preliminary good practice guidance for ASGM in Migori, Kenya. The guidance includes advice on sluice box design including the use of longer sluice channels (at least 3 metres or preferably more) and appropriate sluice box gradients; closed circuit milling; size classification and conditioning of the sluice box feed material; and alternative gravity processing methods to enhance gold recovery; and mercury recovery using retorts. This BGS research was part of the BGS Official Development Assistance (ODA) research project “From source to sink: Quantifying the local and downstream environmental impacts of ASGM”.

Is Hypoalbuminemia a Predictor for Acute Kidney Injury after Coronary Bypass Grafting in Diabetes Mellitus Patients?

Abstract Objective: Acute kidney injury (AKI) is one of the most important complications after coronary artery bypass grafting (CABG) procedure. Serum albumin, which is an acute phase reactant, is suggested to be associated with AKI development subsequent to various surgical procedures. In this study, we research the relation between preoperative serum albumin levels and postoperative AKI development in diabetes mellitus (DM) patients undergoing isolated CABG. Methods: We included a total of 634 diabetic patients undergoing CABG (60.5±9.1 years, 65.1% male) into this study, which was performed between September 2009 and January 2014 in a single center. The relation between preoperative serum albumin levels and postoperative AKI development was observed. AKI was evaluated and diagnosed using the Kidney Disease: Improving Global Outcomes (KDIGO) classification. Results: AKI was diagnosed in 230 (36.3%) patients. Multiple logistic regression analysis was performed to determine the independent predictors of AKI development. Proteinuria (odds ratio [OR] and 95% confidence interval [CI], 1.066 [1.002-1.135]; P=0.043) and low preoperative serum albumin levels (OR and 95% CI, 0.453 [0.216-0.947]; P=0.035) were found to be independent predictors of AKI. According to the receiver operating characteristic curve analysis, albumin level &lt;3mg/dL (area under the curve: 0.621 [0.572-0.669], P&lt;0.001) had 83% sensitivity and 10% specificity on predicting the development of AKI. Conclusion: We observed that a preoperative low serum albumin level was associated with postoperative AKI development in patients with DM who underwent isolated CABG procedure. We emphasize that this adjustable albumin level should be considered before the operation since it is an easy and clinically implementable management for the prevention of AKI development.

Policies Governing Educational Objectives in Professor Motahari’s Epistemology and its Application in the Islamic Republic of Iran

Education and, consequently, trying to determine and explain the policies governing the objectives of the Islamic education is as old as Islam’s 1400 -year-old life. But these objectives in Imami Shiism have not been derived from Shiite scholars’ opinions because Shiites have been away from government and political power. Therefore, written works based on policies governing educational objectives from the epistemology of thinkers such as Professor Motahari in order to apply them in the Islamic Republic of Iran are not available. The present research after explaining the basics of Professor Motahari’s epistemology answers this fundamental question: What are the policies governing educational objectives in Professor Motahari’s epistemology? And how should it be applied in the Islamic Republic of Iran? (Question) The present writing assumes that policies like promoting spirituality, self improvement and developing creativity can be perceived from the foundations of Professor Motahari’s epistemology, policies which can dominate educational objectives. (Hypothesis) The aim is to present the policies governing educational objectives in Professor Motahari’s epistemology. (Objective) Data collection for the present research was done through library research. Then, data were evaluated based on description and analysis and using analytic-inferential method. (Methodology) Presenting the fourteen policies derived from Professor Motahari’s epistemology is new. (Finding)

Outcomes of staged conjunctival flap and corneal transplantation for infectious keratitis resistant to medical treatment

Background/Aims To explore the outcomes of conjunctival flap (CF) followed by keratoplasty in patients with severe infectious keratitis (IK) unresponsive to medical treatment. Methods This is a retrospective monocentric study including 29 eyes of 29 patients with IK resistant to antibiotic treatment associated with stromal ulcer deepening to ≥50% of corneal thickness. All eyes underwent Gundersen’s CF procedure and penetrating keratoplasty (PK), deep anterior lamellar keratoplasty (DALK) or mushroom keratoplasty (MK), at least 4 months thereafter. Outcome measures included corrected distance visual acuity (CDVA), endothelial cell count (ECC), graft survival and complications. Results IK healed in all eyes following CF. The mean time interval between CF and keratoplasty was 16.3±16.1 months. 55% of patients underwent PK, 35% MK and 10% DALK. Mean follow-up duration was 39.6±34.3 months. At the last available follow-up, a CDVA≥20/200 was obtained in 50%, 33.3% and 70% of cases, respectively after PK, DALK and MK. Mean annual endothelial cell loss was 24.5% following PK and 10.7% following MK. Overall, graft failure occurred in 75% of cases after PK, 100% after DALK and 20% after MK. The most frequent complications were endothelial decompensation without immunological rejection (34.5%, after 31.1±25.1 months) and graft rejection (17.2%, after 10.2±7.9 months, all in the PK group). Conclusion CF surgery followed by staged keratoplasty represents an alternative therapeutic approach to avoid high-risk keratoplasty ‘a chaud’ in cases of severe IK.
