Trophic interactions between puma and endemic culpeo fox after livestock removal in the high mountains of central Argentina
Authors: Pia Mónica V. 
Published: March 2013

Abstract
This study presents the first data on the diet of the puma (Puma concolor) and an endemic culpeo fox (Pseudalopex culpaeus smithersi) in the high mountains of central Argentina, based on scat analysis. Trophic interactions of both carnivores were examined from 2003 to 2008 inside a protected area after livestock removal. A total of 604 scats were analyzed. Native species (small cavids and cricetine rodents) were most frequently consumed (58%–100%) by both carnivores. Exotic prey were consumed more in 2003 than in other years by both carnivores. Culpeo foxes consumed a higher number of prey items and a lower mean weight of mammalian prey than pumas. Niche breadth was high for pumas in 2003 and for culpeo foxes in 2004, decreasing in subsequent years with the same tendency in both carnivores. Diet overlap was high in all years. Pumas seemed to prey on available prey items, suggesting a trend toward diet specialization in small prey in both carnivores. Native prey are the most important food items for both carnivores inside the park; these results are encouraging in terms of the resilience of at least some components of the predator-prey assemblage in the high mountains of central Argentina.
Collaborative Writing and Ethical Know-how
Authors: Speedy Jane 
Published: March 2013

It may seem incongruous to come across a ‘sole authored’ text amidst a journal special issue on collaborative writing. For my part the contradiction ‘plays’ eloquently with what it might mean to be/come a singular-yet-silted-up-accumulation of a human being. This paper represents not so much an assemblage (although that, too) as a collectively auto/biographical constellation, accumulation, and distillation of the traces that have remained lying around and about after many decades spent engaged with collective, collaborative and participatory writing. By themselves these sediments and dregs do not amount to much and certainly do not fit together, but as they have accumulated over time they have come to represent something of a body of work. Hence, the conditions of possibility surface for me to give an account of the very particular kinds of ethical know-how that I have witnessed emerging from many groups of people writing together collaboratively within (and to some extent against) the Academy. This paper draws on feminist sensibilities, narrative and poststructuralist ideas, therapeutic practices, Utopian methodologies and multiple writing accumulations over time to suggest that the continued and explicit practice of collaborative writing amongst social researchers alters the academic spaces they inhabit and the ethical know-how that they come by. In time the (albeit fragile) emergence of this different sense of scholarship and scholarly work and even, perhaps, of what it means to be a human being amidst human beings and other elements can begin to rework and expand the social imagination.

ObjectiveIn the field of fine-needle aspiration cytology, the category of suspicious for malignancy (SM) thyroid lesions, that bears 55–85% risk of malignant histology, is a challenging topic in which morphology alone is not always able to make a correct diagnosis. Recently, immunocytochemistry (ICC) has been referred to as helpful in differentiating low- and high-malignant risk lesions andBRAFactivating mutations have been identified in a significant amount of papillary thyroid carcinomas (PTC). The introduction of the liquid-based cytology (LBC) may simplify the application of these techniques to thyroid cytology.DesignOur aim is to evaluate the diagnostic and prognostic role of both ICC andBRAFmutation for the SM category on LBC.MethodsFrom October 2010 through June 2011, 113 LBC cytological cases (including 37 SM and 76 PTC) underwent surgery. All cases were studied forBRAFmutation and ICC.ResultsICC resulted positive in 26 (86.6%) histologically malignant SM with 15 of which (40.5%) expressing aBRAFmutation. Overall, 63 cases showed aBRAFmutation resulting in PTC. Concerning the prognostic role ofBRAFmutation for the two categories, we reported a significant correlation with multifocality, nodal involvement and extra-capsular invasion (P<0.0001).ConclusionsSpecial techniques such as ICC and molecular markers might be successfully carried out on LBC-processed material. For both categories, ICC is more sensitive whereasBRAFanalysis is an interesting support due to its high specificity adding a prognostic value in both SM and PTCs.

Abstract

Objective
To assess the efficacy and safety of laser-assisted percutaneous coronary interventions (PCI) in an unselected population.

Methods
One hundred consecutive patients, who underwent a laser assisted PCI between January 2008 and March 2012, were included in the present study. Fifty-one patients underwent laser ablation for thrombus vaporization (Group 1), 36 patients for neointima/plaque debulking (Group 2) and 13 patients for lesion compliance modification in calcified lesions (Group 3).

Results
The rate of in-hospital serious events was 2%. The cumulative laser success was 82%, and it was significantly higher for Group 1 and Group 2 in comparison with Group 3 (p=0.001). Furthermore, the need for repeat revascularization was significantly higher in the Group 3 compared with the others two groups (46% vs. 8% for Group 1 and 11% for Group 2, p=0.03). The MACE rate was 14%. There was a trend toward a higher MACE rate in the Group 3 compared with others two groups (p=0.05).

Conclusions
Laser ablation is an effective and safe tool for complex PCI. Patients underwent laser for thrombus vaporization or for neointima/plaque debulking had better immediate success and better outcome at follow-up than patients underwent laser for lesion compliance modification.
Laser-assisted myringotomy versus conventional myringotomy with ventilation tube insertion in treatment of otitis media with effusion: Long-term follow-up
Authors: Youssef Tarek Fouad , Ahmed Mohamed Rifaat 
Published: March 2013

Abstract

Background
Otitis media with effusion is the most common cause of conductive hearing loss in the pediatric population. Insertion of ventilation tubes with or without adenoidectomy is the accepted and standard surgical procedure. CO2 laser myringotomy without tube placement has been advocated as an alternative treatment.

Aim
To compare long-term follow-up results of laser versus classical myringotomy with ventilation tube insertion over five years.

Materials and Methods
86 patients with bilateral otitis media with effusion were divided into two groups: laser myringotomy group and myringotomy with ventilation tube insertion group, with follow-up in hearing results and recurrence rates over five years.

Results
The mean patency time of myringotomy in laser group was 23 days, while the mean patency time of the ventilation tubes ears was 4.0 months in myringotomy group. Twelve patients in laser group (13.9%) showed a recurrent otitis media with effusion compared to 9 patients in myringotomy group (10.4%).

Conclusion
Laser fenestration is a less effective alternative to myringotomy and tube placement. The recurrence rates after both procedures did not show statistical significance over long follow-up. It might be considered as an effective alternative to classical surgery and ideal for short-term ventilation.

Abstract

Objective
To investigate the perinatal outcomes of cases with idiopathic polyhydramnios.

Study Design
Retrospective analysis of 160 singleton pregnancies that were under routine surveillance at the department of obstetrics from 2008 to 2010 was performed to assess perinatal outcomes. Finally, 59 cases were included as idiopathic polyhydramnios, and 101 cases were included as controls. Preterm delivery (<37 weeks), gestational age at birth, low birth weight (<2500 g), very low birth weight (<1500 g), macrosomia (>4000 g), 1- and 5-min APGAR scores <7, small for gestational age (SGA) fetuses, large for gestational age (LGA) fetuses, C-section rates, number of fetal distress, admission to neonatal intensive care unit (NICU) after delivery, neonatal death within the first 7 days, and deaths before the age of 1 year were selected as perinatal outcome variables.

Result
Significantly higher preterm labors and low 1- and 5-min APGAR scores were noted in the idiopathic polyhydramnios group compared with the control group.

Conclusion
Although perinatal outcomes are conflicting in literature, idiopathic polyhydramnios warrants close surveillance especially near term.

Published: March 2013

ABSTRACTThe plastic deformation behaviour of single crystals of Pt3Al with a chemical composition of Pt-27 at.%Al was investigated in compression from 77K to 1,273K. The L12 structure is not stable below around 220 K, transforming into either D0c, D0c’ or Pt3Ga structures. {001} slip system was operative for most loading axis orientations while {111} slip system was operative for a narrow orientation region close to [001]. The CRSS for {111} slip gradually decreases in the temperature range where the L12 structure is stable, followed by a sharp decrease above 1,073 K, without showing positive temperature dependence. On the other hand, the CRSS for {001} slip gradually decreases below 673 K and moderately increases above 673 K. Dislocations on {111} tend to align along their screw orientation, suggesting high Peierls stress for their motion, while those on {001} are edge-oriented and fairly curved on a local scale, suggesting relatively low Peierls stress. Dislocations on both {111} and {001} with a Burgers vector b = [$\bar 1$01] dissociate into two collinear superpartials with b = 1/2[$\bar 1$01] separated by an anti-phase boundary.

Published: March 2013

ABSTRACTThe effect of oxygen vacancy (VO) on the electronic and magnetic properties of ZnCoO was studied with first principle methods based on density functional theory (DFT). Calculations were performed, on a periodic 3×3×3 wurtzite supercell of ZnO which consists of 108 atoms with two Co ions substituted for two Zn atoms, using the generalized gradient approximation with Hubbard U correction method (GGA+U). We have studied the interatomic exchange interaction with and without VO for different configurations with different magnetic atom lattice arrangements. The total energies, electronic structures and magnetic moments were calculated for each configuration.

Published: March 2013

ABSTRACTThe accident of the TEPCO Fukushima Dai-ichi Nuclear Power Plant occurred by the 2011 off the Pacific coast of Tohoku Earthquake on 11 Mar. 2011. It is estimated that totally 1.2-1.5x1016 Bq for 137Cs and 1.5-1.6x1017 Bq for 131I were released until the beginning of Apr. and those radionuclides (RN) were deposited on soil surface and forest etc. widely around Fukushima Pref. This work was carried out as one of the investigations for making the distribution maps of radiation dose rate and soil contaminated by RNs which the MEXT promotes. The Geoslicer investigation on the depth distribution of RNs in soil was performed after 3 months from the accident. The investigation was conducted at 11 locations in Nihonmatsu City, Kawamata Town and Namie Town, and soil samples of depth 50 cm to 1 m were taken. Both of 134Cs and 137Cs were detected in all investigated locations, and 129mTe and 110mAg were detected only in locations where radiation dose rates are high. At many locations investigated, radiocaesium more than 99 % distributed within a depth of 10 cm in soil in the surface layer. On the other hand, RNs tended to distribute to deeper part in soil at locations that are supposed to have been used as farmland than in soil in the surface layer, and radiocaesium more than 99 % in soil at locations that are supposed to have been used as farmland also distributed within a depth of around 14 cm. The apparent diffusion coefficients (Da) of RNs derived from penetration profiles near the surface layer showed a tendency to be higher in soil at locations that are supposed to have been used as farmland (Da=0.1-1.5x10-10 m2/s) than in soil in the surface layer (Da=0.65-4.4x10-11 m2/s), and most Da-values were nearly 10-11 m2/s. The distribution coefficients (Kd) by a batch method were in the range of Kd=2,000-61,000 ml/g for Cs and Kd=0.5-140 ml/g for I. Although the Kd-values are different between cation (Cs+) and anion (I-), the Da-values (134Cs, 137Cs, 129mTe and 110mAg) were similar levels. This is considered to be due to that the Da-values were controlled by dispersion by flow of rain water.

Published: March 2013

Abstract
The work was dedicated to investigation of dynamics of epileptic activity in conditions of extremely high frequency electromagnetic waves (EHF) radiation (7,1 mm, 0,1 mW/cm2) upon focal epileptic activity. Epileptic activity was penicillin-induced (10,000 IU/ml) in the frontal region of the brain cortex in myorelaxed and artificially ventilated rats under acute experimental condition. Thermal effects were absent as far as absorbed dosage of energy did not exceed 0,1 J/ animal. It was established that preliminarily performed hypogeomagnetic period (3,0 h) with the inductivity of geomagnetic field at 5×10−8 Tesla caused the intensification of antiepileptic effects of EHF (15,0 min of exposure). It was pronounced in the form of decrease of foci intensity and significant reduction of lifespan of foci — up to 115,3±13,4 minutes, which was both significant when compared with separate effects of hypogeomagnetic influence (187,3±12,5 min) and EHF (15,0 minutes of exposure) effect (164,2±12,5 minutes) (P<0,05). Besides, EHF (15,0 min) which was made after 3,0 h exposure to hypogeomagnetic influence suppressed generalized seizures in amygdalarly kindled rats.
Comparison of anthocyanins present in grapes of Vitis vinifera L. varieties and interspecific hybrids grown in the Czech Republic
Authors: Balík Josef , Kumšta Michal , Rop Otakar 
Published: March 2013

AbstractAnthocyanins present in the grapes of nine grapevine (Vitis vinifera L.) varieties and ten interspecific hybrids were compared. Total anthocyanin levels were determined in fresh grapes and the values ranged from 0.50 g kg−1 to 4.99 g kg−1. A total of twenty-two different anthocyanins were identified. Malvidin 3-glucoside was the most abundant anthocyanin, with concentrations ranging from 30 % to 64 % of the totals observed. The ratio of acetylated to coumaroylated malvidin and peonidin derivatives ranged from 0.09 (variety: Regent) to 1.34 (variety: Cerason), depending on the variety. Diglucosylated anthocyanins were not found in particular interspecific hybrids such as the teinturier XIV 26–56, Laurot, Merlan, and Nativa.

Published: March 2013

Unpalatable and unwanted native or invasive plants that have adverse impact on the forage in the grazing area are rangeland weed. Climate change, introduction of new species, disturbance and fragmentation of land are causative factors for spreading native or invasive weed infestation on rangelands. Senecio chrysanthemoides is a serious obnoxious weed on Himalayan rangeland area. It is densely populated on plain and left places of shed constructed area consequent rangeland degraded, displacing desirable species, degrading systems, decreasing productivity and increase management costs. To arrest infestation of weed, mechanical control measure was followed but unplanned mechanical control measure was inadequate. Up-rooting weed earlier flowering was more effective than other life form of weed.DOI: http://dx.doi.org/10.3126/on.v10i1.7745
Field Observations on Stone Curlews in and around Kurukshetra, Haryana, India
Authors: Gupta R.C. , Kaushik T.K. 
Published: March 2013

Stone Curlew, albeit claimed to be a wader bird of wetlands, is more biased towards dry or semi-dry shores of wetlands and open grasslands in Kurukshetra environs. Although, reported to be a nocturnal bird, it was often observed in day time here. The diurnal visibility of nocturnal Stone Curlews in Kurukshetra certainly points towards its distracted, disturbed, fragmented, scarce habitat so as to compel it to take shelter beside walls in a most unsafe state. The present studies hint towards the fact that, they are summer migratory often seen between April to September but certainly not in November, December and January. They shuttle between different spot in a given area indicating its habitat range up to 1 to 3 km or so. They are facing difficult circumstances due to loss of habitat; so much so, their feeding spots are not traceable at all. This study proves that the scattered and isolated groups of a nocturnal bird like Stone Curlew are compelled to retire in full view of one and all during daytime and hence are immensely vulnerable. Their survival is threatened. Given the continuance of present adverse conditions, they will no more be seen in the next 10-15 years in Haryana, specially in Kurukshetra.

Published: March 2013

In this study, the effects of various kinds of sawdust and supplements on the yield of Ganoderma lucidum were investigated in artificial cultivation. The sawdust of Alnus nepalensis, Shorea robusta and Dalbergia sisoo and supplements of rice bran , wheat bran, corn flour and gram flour were used as substrates in Ganoderma lucidum cultivation . Sawdust alone was used in control as a substrate media in the cultivation. Significant differences (P< 0.05) were found among varieties of sawdusts and supplements. Similarly significant differences (P<0.05) were found in sawdust with supplements and without supplements in yield and biological efficiency. Dalbergia sisoo sawdust could not give yield in ambient condition; Shorea robusta gave very low yield and biological efficiency. Alnus nepalensis gave good yield and biological efficiency compared to the other sawdust.The highest yield and Biological efficiency were obtained from gram flour compared to the other brans. Alnus nepalensis sawdust supplemented with gram flour showed higher yield among all treatments. Supplementation showed positive role in mycelia growth and yield of mushroom.DOI: http://dx.doi.org/10.3126/on.v10i1.7781
Experimental and numerical investigation of the sintering rate of snow
Authors: Herwijnen Alec Van , Miller Daniel A. 
Published: March 2013

AbstractSintering rates in snow were investigated by measuring changes in penetration resistance with time and by using a numerical snow metamorphism model. Periodic Snow Micro Penetrometer (SMP) measurements were performed on uniform snow samples covering a wide range of densities. The mean penetration resistance of snow increased with time according to a power law with an average exponent of 0.18. Simulated changes in the bond-to-grain ratio for simplified spherical ice grains followed a power law with an average exponent of 0.18, showing that the mean penetration resistance, as measured with the SMP, closely relates to bond-to-grain ratio in snow. For lower-density snow samples, consisting mostly of dendritic snow morphologies, the measured increase in penetration resistance was lower. This is likely the result of two competing processes: (1) strengthening of the snow sample due to the creation and growth of bonds and (2) weakening of the snow sample due to the formation of unbonded small rounded particles at the expense of larger dendritic forms. On the other hand, the rate of increase in penetration resistance for snow samples consisting of closely packed depth hoar was similar to that of rounded grains.
