Authors: Tret’yakov Aleksey , Tyrtyshnikov Eugene , Ustimenko Aleksey 
Published: July 2017

Abstract
The existence of a nonsingular matrix is proved for any space of square symmetric matrices with a trivial quadratic kernel. Some corollaries from this result are obtained for construction of solvers of nonlinear equations and problems of conditional optimization with a Jacobi matrix of incomplete rank based on the theory of p-regularity for p = 2. Some remarks for the case p ⩾ 3 are presented.

Published: July 2017

Abstract
This paper presents physical and mechanical properties of cementitious composites/plasters containing cellulosic fibers in portion 2.0% and 5.0% of filler replacement after 28 days of hardening. Cellulosic fibers (Greencel) originated from bleached wood pulp and unbleached waste paper used in this experimental work were characterized from the point of view cellulose structure. Experimental investigations reveal that adding cellulosic fibers reduces composites density (up to 8.2 %) in comparison with composites without any fibers. Moreover, the presence of wood pulp and recycled fibers in composites cause higher values of water absorbability than sample without fibers. Also, the decrease in compressive strength values for tested fiber cement plasters was observed (14.1 - 18.0 MPa) in comparison to reference sample (26.6 MPa). But the identified compressive strength values are in accordance with European standard (5 MPa) for plasters.

Abstract
Doing the replacement of old wooden windows in a new plastic windows, in the old buildings, we get the great reducing of the building heat loss. Simpler maintenance and attendance of window is the next advantage. New windows are characterized by better tightness. The aim of the article is determination due to the performed experimental measurements, how much more are reduce the uncontrolled ventilation that is caused of the infiltration windows. In the article there is presented the experimental measurement of indoor air quality in the room in two phases. In the first phase there is the room installed by 55 year old wood window. In the second phase there is the same room installed by new plastic window. Due to the experimental measurement of indoor air quality it is calculated intensity of ventilation - infiltration. These results of ventilation intensity are reciprocally compared.
Property and Sovereignty: How to Tell the Difference
Authors: Ripstein Arthur 
Published: July 2017

AbstractProperty and sovereignty are often used as models for each other. Landowners are sometimes described as sovereign, the state’s territory sometimes described as its property. Both property and sovereignty involve authority relations: both an owner and a sovereign get to tell others what to do — at least within the scope of their ownership or sovereignty. My aim in this Article is to distinguish property and sovereignty from each other by focusing on what lies within the scope of each. I argue that much confusion and more than a little mischief occurs when they are assimilated to each other. The confusion can arise in both directions, either by supposing that property is a sort of stewardship, or that sovereignty is a large-scale form of ownership. One of the great achievements of modern (i.e., Kantian) political thought is recognizing the difference between them.
Numerical Study on the Secondary Air Performance of the Film Holes for the Combined Impingement and Film Cooled First Stage of High Pressure Gas Turbine Nozzle Guide Vane

Published: July 2017

Abstract
The present numerical investigation of Leading Edge (LE) Nozzle Guide Vane (NGV) is considered with five rows of impingement holes combined with five rows of film cooled for the secondary coolant flow path analysis. The coolant mass flow rate variations in all the LE rows of the film holes externally subjected to the hot main stream were obtained by making a three-dimensional computational analysis of NGV with a staggered array of film cooled rows. The experiments were carried out for the same NGV using Particle Image Velocimetry technique to determine the effused coolant jet exit velocity at the stagnation row of film holes as mentioned in reference [Kukutla PR, Prasad BVSSS. Secondary flow visualization on stagnation row of a combined impingement and film cooled high pressure gas turbine nozzle guide vane using PIV technique, J Visualization, 2017; DOI: 10.1007/s12650-017-0434-6]. In this paper, results are presented for three different mass flow rates ranges from 0.0037 kg/s to 0.0075 kg/s supplied at the Front Impingement Tube (FIT) plenum. And the mainstream velocity 6 m/s was maintained for all the three coolant mass flow rates. The secondary coolant flow distribution was performed from SH1 to SH5 row of film holes. Each row of a showerhead film hole exit coolant mass flow rate varied in proportion to the amount of coolant mass rates supplied at the FIT cooling channel. The corresponding minimum and maximum values and their film hole locations were altered. The same behaviour was continued for the coolant pressure drop and temperature rise from SH1 to SH5 row of film holes. Owing to the interaction between hot main stream and the coolant that effuses out of the film holes, occasional presence of hot gas ingestion was noticed for certain flow rates. This caused nonlinear distribution in mass flow, pressure drop and temperature rise. The minimum flow rate results estimate oxidation of NGV material near the film cooled hole. And the effect of hot gas ingestion on the ejected film cooled jet which would recommends effective oxidation resistant material which in turn leads to better durability of the NGV surface.

ObjectiveAutoimmune thyroid disease (AITD) and psoriatic disease share auto-immunological components. Few studies have investigated the link between both, yielding inconclusive results.DesignWe assessed the association of AITD with psoriatic disease in a prospective cohort study and performed a systematic review and meta-analysis.Methods8214 participants of the Rotterdam Study (RS) with thyroid peroxidase antibodies (TPO-Abs), thyroid-stimulating hormone (TSH) and/or free thyroxine (FT4) measurements and information on psoriatic disease were included. We performed logistic and Cox regression analyses and a systematic literature search in several electronic databases on AITD and psoriatic disease. We pooled odds ratios (ORs) of included studies using the Mantel-Haenszel method, while adding RS data on prevalent psoriatic disease.ResultsWithin the RS, we found no association between TPO-Ab positivity and psoriatic disease. There was a positive trend between TSH and prevalent psoriatic disease, and between FT4 and incident psoriatic disease, although not significant. Out of 1850 articles identified, seven were included in the systematic review and four in the meta-analysis. The risk of psoriatic disease (pooled OR) was 1.71 (confidence interval (CI): 1.27–2.31) for TPO-Ab positivity, 1.25 (CI: 1.14–1.37) for AITD and 1.34 (CI: 1.16–1.54) respectively, and 1.17 (CI: 1.03–1.32) for hypothyroidism and hyperthyroidism.ConclusionsOur meta-analysis suggests that TPO-Ab positivity, hypothyroidism and hyperthyroidism might be associated with prevalent psoriatic disease. However, there are only few studies with large heterogeneity regarding psoriatic disease definition and indication of publication bias. Additional prospective data are needed to assess the association of AITD with incident psoriatic disease.
Integrity changes of cement sheath due to contamination by drilling fluid

Published: July 2017

Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), thermogravimetric analysis (TGA), infrared spectroscopy and x-ray diffraction were used to explore the effects of drilling fluid contamination on the mechanical and porosity–permeability properties of cement stone. The experimental results showed that the mechanical and porosity–permeability properties deteriorated due to contamination by drilling fluid. The deterioration in properties was found to be more serious with an increase in drilling fluid content: for a drilling fluid content of 30%, mechanical properties were reduced by about 50% compared with those of pure cement stone, and porosity and permeability were increased by 7·9% and 0·369 millidarcy (3·6 × 10−12 cm2). SEM, EDS and TGA revealed that chemical incompatibility between drilling fluid additives and cement slurry is the main reason for contamination: the additives contain many functional groups that are not compatible with cement slurry (e.g. carboxylate (–COO−) and amide groups (–CONH2)). These additives easily generate a flocculation mechanism when in contact with cement slurry. They are adsorbed onto the surfaces of cement grains, thus coating the cement particles, reducing the hydration reaction rate and destroying development of the cement stone microstructure, leading to a reduction in strength and an increase in porosity and permeability.
Scientific and non-scientific information in the uptake of health information: The case of Ebola
Authors: Falade Bankole A. , Coultas Clare J. 
Published: July 2017

The Ebola virus disease outbreak in West Africa (2013–2016) claimed over 10 000 lives in less than 18 months. Low levels of familiarity with the disease, ease of transmission, scale of infection, gruesomeness of symptoms, lack of cure and high fatality rate created a global panic. From the perspective of the social psychology of communication and content analysis, this study examines media coverage of the crisis in Africa with a view to unpacking the scientific and non-scientific information that may have framed public understanding of the disease. Findings show that accepting scientific advice was not unproblematic, because of the similarity of early symptoms with known diseases such as Lassa, dengue and malaria fevers. Cultural and religious actors and beliefs posed a paradox for believers as the public assimilated disease prevention information into existing norms and practices. Rumours and conspiracy theories about Western governments and pharmaceuticals also contributed to the rejection of the scientific explanation of its origin. Fear of the devastating effects of the disease and the lack of a cure led to the stigmatisation of the infected and treatment centres and ultimately to public revolts. Findings show the importance of non-scientific information and actors in matters of health and illness in Africa.

Significance:

Scientific knowledge is not enough to change health behaviour. Non-scientific knowledge and actors, traditional and religious practices, rumours and conspiracy theories must all be factored into efforts to address behavioural change.

Authors: S. Chandrashekar , Muralidhar Suraj 
Published: July 2017

Background: India is one of the top ten diabetes mellitus (DM) countries. Thus, the aim of this study was to survey the prevalence of DFU risk factors and DFU prevalence among type 2 diabetes mellitus (T2DM) patients.Methods: An epidemiological study was conducted on an outpatient basis in K. R. hospital, Mysuru. All T2DM participants were ≥ 18 years were included. Demographic and foot care behavior were assessed using minimum data sheet (MDS). Meanwhile, presence of risk factors was evaluated for neuropathy and presence of angiopathy was evaluated with ankle brachial index (ABI) by using a hand-held doppler both dorsal and posterior tibial.Results: At the end of study, 249 T2DM participants were enrolled. The prevalence of DFU risk factors was 55.4% (95% CI: 53.7% - 57.0%), and prevalence of DFU was 12% (95% CI: 10.3% - 13.6%).Conclusions: Even though the prevalence of DFU is high, identification associated factors for presence of risk and DFU has not been integrated into national guideline. Thus, preventive strategies should be introduced at early stage to prevent presence of risk and DFU.

Published: July 2017

Background: Acute rheumatic fever (ARF) is a multisystem disease resulting from an autoimmune reaction to infection with group A beta haemolytic streptococcus. Acute rheumatic fever commonly occurs between 5-14 years of age.1 The major concern relating to acute rheumatic fever is often not the episode itself but the long-term consequences of damage to heart valves (Rheumatic heart disease (RHD) that often results from recurrent episodes of acute rheumatic fever. Rheumatic heart disease (RHD) continues to be a major public health problem and a common cause of morbidity and mortality in many parts of India.2Methods: 50 consecutive patients admitted with the diagnosis of acute rheumatic fever in Medicine Department, Katihar Medical College and Hospital, Bihar, India were studied. A detailed clinical history of these patients including presenting symptoms were noted. Physical examination of all systems was done and a diagnosis of acte rheumatic fever was made according to WHO Criteria (2002-2003) for the diagnosis of rheumatic fever and rheumatic heart disease (Based on the Revised Jones Criteria). Echocardiography of all 50 patients were done.Results: Mean age of patients diagnosed with ARF was 14.20±7.02 years. Out of 50 patients, 32 (64%) were female and 18 (36%) were male. Joint pain was the commonest presenting complain, 35 (70%) patients, followed by fever in 21 (42%) patients. Among Jones major manifestations 36 (72%) cases had carditis, 32 (64%) had arthritis, 6 (12%) had subcutaneous nodules, 5 (10%) had erythema marginatum and5(10%) had Sydenham’s chorea. In patients with carditis, 25 (69.44%) had mitral regurgitation (MR) only while 10 (27.77%) had MR with aortic regurgitation (AR) and 1 (2.77%) patient had organic tricuspid regurgitation (TR) with mitral regurgitation and aortic regurgitation. Out of 36 patients with carditis, 10 (27.77%) patients did not have any clinical evidence of carditis and were detected by echocardiography only.Conclusions: Commonest complain in patients with rheumatic fever was joint pain followed by fever. In patients with carditis, all had mitral regurgitation(MR), with 1/3rd of these patients having associated aortic regurgitation(AR). 1/3rd of patients with carditis were detected by echo only and therefore, echo should be included in diagnostic criteria for acute rheumatic fever. None of the patients who developed rheumatic fever was on penicillin prophylaxis.

Pearl Millet and Cowpea Intercrop Response to Applied Nutrients in West Africa
Authors: Maman Nouri , Dicko Mohamed , Abdou Gonda , Kouyate Zoumana , Wortmann Charles 
Published: July 2017

Core Ideas
Pearl millet and cowpea intercrop production is important in the Sahel.
Inadequate nutrient supply constrains crop growth.
Pearl millet sole crop nutrient response information is applicable for intercropping.
Application of N and P to intercrop compared to sole crop has more profit potential.
In the Sahel, crop production is dominated by pearl millet [Pennisetum glaucum (L.) R. Br.] cropping systems including intercropping with cowpea [Vigna unguiculata (L.) Walp]. The research objectives were to determine pearl millet sole crop (PMSC) and intercrop nutrient response functions, profit opportunities from fertilizer use, and a means of relating intercrop to PMSC response. Pearl millet–cowpea trials were conducted in Niger and Mali. The treatment structure was an incomplete factorial with five, four, and four levels of P, N, and K, respectively. Response functions were determined for intercropping with cowpea yield converted to a pearl millet grain yield equivalent for ratios of cowpea to pearl millet grain value (CpPm) ranging from 1 to 5 kg kg−1. Response functions were also determined in consideration of fodder value. A method of adjusting PMSC response coefficients with CpPm as the independent variable was developed for determination of intercrop response functions. Yields and responses to nutrients were low but adequate for profitable N and P use. Value of intercrop production ranged from 50 to 125% more compared with PMSC for CpPm of 2 and 4, and the respective response to 10 kg ha−1 P was 28 and 135% more with intercrop. Consideration of fodder added 23% to the yield value. Application of N and P for intercrop compared with PMSC production has much more profit potential. The ability to apply PMSC functions in determination of pearl millet–cowpea responses to applied nutrients offers a means to improve fertilizer use for the intercrop.
Does Liquid Swine Manure Application Timing and Nitrapyrin Affect Corn Yield and Inorganic Soil Nitrogen?
Authors: Vetsch Jeffrey A. , Scherder Eric F. , Ruen David C. 
Published: July 2017

Core Ideas
Nitrapyrin (Instinct) effectively slowed nitrification of swine manure.
Delaying fall application of swine manure increased corn yields and N availability.
Instinct enhanced corn production in years with greater than normal precipitation.
Fall application of liquid swine (Sus scrofa) manure (LSM) is preferred but it can increase N loss potential. Delaying application of LSM or adding a nitrification inhibitor could reduce N losses. This study measured the effects of LSM application timing and nitrapyrin [2‐chloro‐6‐(trichloromethyl) pyridine] as Instinct on soil inorganic N and corn (Zea mays L.) production. Field experiments were conducted from 2010 through 2014 on clay loam soils (Aquic Hapludolls). Treatments consisted of two fall application timings (early and late) and three rates (0, 2.56, and 5.11 L ha−1) of Instinct. Manure was injected 10‐cm deep at 134 kg of available N ha−1. Additional treatments included a control and 134 kg ha−1 of N as anhydrous ammonia (AA) with and without nitrapyrin as N‐Serve. Treatments were arranged in a randomized‐complete block design with four replicates. Late fall application of LSM and Instinct use resulted in greater fall and early spring NH4–N concentrations in manure bands. When averaged across years, LSM applied late increased corn grain yields 0.5 Mg ha−1 compared with early application and yields were 0.5 to 0.7 Mg ha−1 greater with Instinct than without. An interaction between main effects showed the yield response to Instinct was greatest when LSM was applied early. Total N uptake and removal were greater with Instinct than without Instinct. In this study, delaying LSM application until late fall (November) and using nitrapyrin (Instinct) increased corn yields and N uptake in years with greater than normal spring precipitation.
