Microcrystalline iron sulfide particles in coal: A Moessbauer study: Final report, March 1, 1986-February 28, 1987

Field: Chemistry (Physical Sciences)

This report presents progress achieved in the first eight months of a continuing project. In this time, new equipment has been installed and tested, and preliminary experiments on all sample types to be investigated have been completed. Collection of data for iron sulfide standards and for one microcrystalline iron oxide sample is nearly complete. Analyses of the data are in progress. The objective of this research project is to employ Moessbauer spectroscopy to examine microcrystalline iron sulfides in coal chars to determine the extent to which highly dispersed iron sulfide catalysts may be present in the chars. The Moessbauer spectrometer used in this project is a Ranger Scientific MS-900. All the data have been collected in a symmetric mode at velocities of 9.8 mm/s and 11.3 mm/s. Low temperatures (4.3K) are obtained with a liquid He dewar made by Lakeshore Cryotronic. A typical low-temperature experiment lasts about 7 days. The Moessbauer spectra are analyzed using the program MOSFIT, which employs an iterative least-squares fitting method to find the best fit of Lorentzian functions to the experimental spectrum. Fourier smoothing techniques are employed. Analysis of the spectra of two char samples indicates that the concentration of iron sulfides is small. Superparamagnetismmore » in the char spectra is evident; however, particle size estimates will be obtained. One of the standard samples of iron oxide was studied at different temperatures. The blocking temperature for the preparation of this sample is between 9.6 and 24K. Particle size estimates are between 94 and 128 A. 10 refs., 7 figs.« less
Process Pad

Field: Computer Science (Physical Sciences)

This paper introduces Process Pad, an interactive, low-cost multi-touch tabletop platform designed to capture students' thought process and facilitate their explanations. The goal of Process Pad is to elicit students' think-aloud narratives that would otherwise be tacit, in other words, "learn to explain," and "explain to learn." Our focus is on identifying and understanding key design factors in creating opportunities for students to externalize and represent their mental models using multimodal data. From our user observations, we gleaned four design principles as essential criteria based upon which we refined our design: flexibility, tangibility, collaboration and affordability.
Input substitution and technological development on Finnish dairy farms for 1965-1991: Empirical application on bookkeeping dairy farms

Field: Arts and Humanities (Social Sciences)

The study presents an attempt to gain a better understanding of the input substitution and technological development on Finnish dairy farms. The dual approach of the neoclassical production and cost theory is applied. A system of derived demand and cost functions is estimated using a representative dairy farm data and panel data of bookkeeping Finnish dairy farms. The flexible translog cost function is utilized to solve the empirical research problem. The cost function study is chosen, because it makes it possible to study production of farms operating in the area of decreasing average costs. According to the results, inputs are for the most part substitutes with each other. With the existing production technology, the substitution of inputs for other inputs is inelastic. The own price elasticities are also inelastic. Technical change is purchased feed-saving and other inputs-using. The average annual rate of technical change was 1.3 percent. The new production chains resulting from technical change have made it possible to increase the size of dairy farms. Increasing the size of dairy farms should be allowed so in order to make it possible to utilize the advantages related to the economies of size.

THE ROLE OF THE KIDNEY IN THE REGULATION OF PLASMA CALCIUM

Field: Medicine (Health Sciences)

Parathyroid hormone increases calcium absorption from the gut, increases calcium resorption from bone and increases tubular reabsorption of calcium by the kidney. These actions of parathyroid hormone all result in a rise in blood calcium. This rise in calcium concentration subsequently inhibits hormone secretion by the parathyroid glands. Such a negative feed-back mechanism maintains the blood calcium within narrow limits in the face of fluctuations in calcium intake utilisation and loss.

Efficacy of Soil Insecticides Against Sucking Pests of Potato

Field: Agricultural and Biological Sciences (Life Sciences)

Field experiments were conducted at three locations for two seasons, 2018 to 2020 to evaluate the efficacy of soil insecticides against sucking pests of potato. Lowest cumulative mean number of whiteflies was observed with fipronil 0.3G @ 25 kg/ ha, and it was on par with its dose of 20 kg/ ha, cartap hydrochloride 4G @ 20 and @ 25 kg/ ha; overall reduction in whiteflies over control ranged between 56.70 and 59.04% at Jalandhar; 53.17 to 60.89% at Modipuram, and 57.33 to 62.40% at Gwalior. Similar trends were noted for aphids, leaf hoppers and thrips. Based on tuber yield and benefit cost ratio, cartap hydrochloride 4G @ 20 kg/ ha (2.62) and fipronil 0.3G @ 20 kg/ ha (2.47) were found to be the most effective against the sucking pests of potato. Hence, both these can be recommended in potato in place of phorate 10G.

A trial of idazoxan and yohimbine in erectile dysfunction

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Abstract Forty successive referrals to the York Psychosexual Clinic suffering from erectile dysfunction were placed randomly on a double blind crossover trial of idazoxan, which is a new α2-adrenoreceptor antagonist, or on to a matched placebo. The patients were rated over a period of four weeks; after a week's wash out period a further four weeks' treatment with the alternative preparation was commenced, the rating scales being continued. At the end of the nine week period non-responders were then placed on yohimbine 5 mg tds to 10 mg tds and rated for a further four weeks to establish whether any of the failure group improved on a standard drug currently in use for the treatment of impotence at some clinics. Fifty percent of the idazoxan programme failures made a response to yohimbine.
Uniform Formation of Fine Grained Ferrite Structure through Multi-directional Deformation

Field: Materials Science (Physical Sciences)

A multi-directional deformation thermo-mechanical treatment simulator was designed and developed to verify the prediction by the FE-analysis on the effect of bi-directional deformation which can introduce a large plastic strain widely in a specimen. Using this simulator, both uni-directional and bi-directional deformations were performed for a 0.16%C-0.4%Si-1.4%Mn steel with a prior austenite grain size of 300 μm at 1073K at a strain rate of 1/s. The microstructure was composed of polygonal ferrite and intragranular Widmanstätten ferrite in the uni-directional deformation specimen. On the other hand, the half thickness of the specimen was composed of fine polygonal ferrite in the bi-directional deformation specimen. This region corresponds well to the region having a plastic strain of more than 2. The uniform formation of the fine polygonal ferrite due to the wide introduction of the large plastic strain was verified for the bi-directional deformation.
A giant cause of a low pressure headache

Field: Medicine (Health Sciences)

We present an unusual case of low pressure headaches in a patient with Marfan’s Syndrome caused by a giant anterior sacral meningocele. The patient, a lady with Marfan’s Syndrome and previous cardiac and ocular complications, presented initially with recurrent postural headaches, worse on standing, occurring over a 5 year period. During these periods she would develop pulsatile tinnitus on standing and also felt the headaches improved when she breathed in. CT brain scans, MRI scans of head and neck and recurrent lumbar punctures done during this period where normal although opening pressures were not recorded. Since 2007 she has had a chronic daily headache with no associated features. Neurological examinations were normal throughout her presentations. A MRI of her lumboscaral spine was performed in 2011 with showed a massive fluid filled structure in the pelvis and a diagnosis of a giant dural ectasia or anterior sacral meningocele was made. Anterior sacral meningoceles are an uncommon congenital abnormality consisting of a spinal fluid filled sac in the pelvis communicating with the subarachnoid space. They are associated with Currarino’s syndrome (presacral mass, a sacral defect and an anorectal malformation) and Marfan’s syndrome. Patients most often present with abdominal symptoms, symptoms of cauda equina or with headaches (both high and low pressure). Neurological symptoms may respond to surgical treatment of the meningocele.

Recent Advances in Cross‐Dehydrogenative Couplings (CDC) of C−H Bond in Aqueous Media

Field: Chemistry (Physical Sciences)

Abstract To develop highly efficient synthetic reactions is quite important in organic chemistry. Cross dehydrogenative couplings (CDC) utilize C−H bonds of substrates to construct new C−X (X=C, S, O, N, P) bonds. For CDC, the pre‐functionalization of reaction substrates can be avoided and the C−X (X=C, S, O, N, P) bonds can be newly formed by simple and efficient synthesis routes. Meanwhile, water is increasingly used as a substitute for organic solvents in cross‐dehydrogenative coupling because of its rich content, non‐toxicity, and non‐ flammability. In recent years, organic chemists are devoted their efforts to explore the cross dehydrogenative couplings (CDC) in aqueous phase which feature high atom utilization rate and environmental friendliness. Herein, we summarized the recent advances in the construction of C−C, C−S, C−O, C−N, and C−P bonds through CDC reactions of C−H bonds in water. magnified image
PPP1CC2 levels are highly regulated in testis to ensure normal spermatogenesis and male fertility

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

PPP1CC2 is one of the four isoforms of type 1 serine/threonine protein phosphatase (PP1). PPP1CC1 and PPP1CC2 are two alternatively spliced isoforms of Ppp1cc gene. Targeted deletion of Ppp1cc gene causes male infertility; females are normal suggesting that PPP1CC isoforms are indispensable in testis. To determine the specific role of the two PPP1CC isoforms, we transgenically expressed PPP1CC2 driven by the testis specific Pgk2 promoter. The results show that fertility as determined by sperm number, morphology and motility is restored in Ppp1cc null mice in lines where transgene expression was relatively high. The goal of the present work was to determine if overexpression of PPP1CC2 in wildtype (+/+) testis affected spermatogenesis and sperm function. Wild type mice were crossed with Ppp1cc2 transgenic mice (+/−; Tg+) to derive lines with three copies of Ppp1cc2 gene (two endogenous and one transgenic copy; +/+, Tg+). Analysis of +/+;Tg+ adult mice show that they are phenotypically indistinguishable from +/+ and +/− control littermates in terms of sperm morphology, motility and number. Western blot analysis showed there was no increase in PPP1CC2 levels despite a dramatic increase in Ppp1cc2 mRNA levels in testis of +/+;Tg+ compared to +/+ mice. We suggest that homeostatic mechanisms operating post‐transcriptionlly limit the steady state amounts of testis PP1CC2 levels. (NIH ……..)
Anti-inflammatory and gastroprotective activity of Hypericum perforatum oil extracts

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Oil extracts of flowering tops of Hypericum perforatum are popular remedies in traditional medicine of many countries. They are used externally for the treatment of wounds, first-degree burns, acute and contused injuries, myalgia and internally for dyspeptic complaints [1]. We prepared H. perforatum oil extracts in three different ways: by maceration of the fresh flowering tops in sunflower oil exposed to sunlight for 40 days (extract A) [2], by maceration of dried flowering tops with 96% EtOH followed by evaporation of the solvent in the presence of sunflower oil (extract B) [3], and by digestion of dried flowering tops in sunflower oil for 3h (extract C) [4]. Carrageenan-induced rat paw oedema test has been used as an experimental model for screening the anti-inflammatory activity according to the modified method of Oyanagui and Sato [5]. The extracts were administered p.o. in a dose of 1.25ml/kg to rats and compared with indomethacin, which was used as a reference at a dose of 8mg/kg p.o. Statistical analysis was performed by the Mann-Whitney exact test, and P<0.05 was considered as significant. The obtained anti-inflammatory effect was 88%, 96% and 77% for extract A, B and C, respectively. Indomethacin had an anti-inflammatory effect of 81%, but large gastric lesions were detected. When the investigated extracts (1.25ml/kg p.o.) were concomitantly given with indomethacin (8mg/kg p.o.), the gastric lesions were significantly reduced. Extract B showed the highest gastroprotective activity.
