The Weave: A Suburban Work

As first a spectator, the architect is always already an agent at work in the creation of the difference of which Duchamp speaks. This occurs through the simple misreading of an idea-philosophy offered forth for contemplation

High turnover in electro-oxidation of alcohols and ethers with a glassy carbon-supported phenanthroimidazole mediator.

Glassy carbon electrodes covalently modified with a phenanthroimidazole mediator promote electrochemical alcohol and ether oxidation: three orders of magnitude increase in TON, to ∼15 000 in each case, was observed compared with homogeneous mediated reactions. We propose the deactivation pathways in homogeneous solution are prevented by the immobilization: modified electrode reversibility is increased for a one-electron oxidation reaction. The modified electrodes were used to catalytically oxidize p-anisyl alcohol and 1-((benzyloxy)methyl)-4-methoxybenzene, selectively, to the corresponding benzaldehyde and benzyl ester, respectively

Center Pivot Rental Rates With and Without Adjustments for Dryland Corners

Cash rental rates on irrigated land have been on a strong upward trend in recent years, which has continued into 2013. Obviously, with heavy demand tenants have tended to bid aggressively. In an effort to obtain leases, the practice of bidding on a straight per acre rate for both the irrigated cropland and the dryland crop acres in the corners has become more common by tenants. After several years with normal or above rainfall, yield differentials on dryland corner acres were small enough to convince some tenants to bid essentially a per acre irrigated cash rent for the whole cropland parcel

Herschel Observations of Debris Discs Orbiting Planet-hosting Subgiants

Debris discs are commonly detected orbiting main-sequence stars, yet little is known regarding their fate as the star evolves to become a giant. Recent observations of radial velocity detected planets orbiting giant stars highlight this population and its importance for probing, for example, the population of planetary systems orbiting intermediate mass stars. Our Herschel survey observed a subset of the Johnson et al program subgiants, finding that 4/36 exhibit excess emission thought to indicate debris, of which 3/19 are planet-hosting stars and 1/17 are stars with no current planet detections. Given the small numbers involved, there is no evidence that the disc detection rate around stars with planets is different to that around stars without planets. Our detections provide a clear indication that large quantities of dusty material can survive the stars' main-sequence lifetime and be detected on the subgiant branch, with important implications for the evolution of planetary systems and observations of polluted or dusty white dwarfs. Our detection rates also provide an important constraint that can be included in models of debris disc evolution.Comment: 12 pages, MNRAS, accepte

Revised Innocent Spouse Rules Offer Greater Tax Relief

When a married couple files a joint tax return, both spouses become jointly and severally liable for the income taxes due, including any additional taxes, interest, and penalties determined at a later date. In the event of an underpayment of income tax, the IRS can proceed against either spouse to collect the entire tax deficiency. This places a spouse in a precarious position in situations where the other spouse deliberately omits income or overstates deductions on a jointly filed income tax return, even if the spouse is totally unaware of the other\u27s transgressions. Relief from joint and several liability is available to spouses that signed and filed a joint return for the year in which an income tax deficiency is assessed and who satisfy requirements under one of the following 3 areas: 1. innocent spouse relief under section 6105(b), 2. separate liability relief under section 6015(c), or 3. equitable relief under section 6015(f)
