Internal Combustion Wave Rotors for Gas Turbine Engine Enhancement

Recent research in internal combustion wave rotor technology proposed operating cycles with declarative and detonative Combustion. Earlier research, examining primarily deflagration, sought to improve on pressure exchanger wave rotor cycles topping a conventional gas turbine. Turbulent premixed combustion with reasonable flame speeds is predicted to allow operating frequency comparable to pressure exchanger cycles. Cycles that completely evacuate the wave channel to highand low-pressure turbines may require faster combustion. More recent research on detonation cycles followed developments in pulse detonation engine technology. While detonative combustion is extremely fast, the wave cycle must isolate peak pressures and velocities from Turbo machinery. Ignition presents a degree of uncertainty for all designs, and fuel distribution control is a critical strategy. The relative merits and challenges of various modes of combustion and cycles are discussed for typical applications in propulsion and Power generation. Research and development needs, and recommended experimental strategies are described and evaluated.
Effects of Prolonged Consumption of Water with Elevated Nitrate Levels on Certain Blood Serum Trace and Macro Elements of Dairy Cattle and Use of Clinoptilolite for their Amelioration

Elevated levels of nitrates in feed and water can pose a significant risk for dairy cattle, due to their cumulative action. The effect of prolonged consumption of water naturally contaminated with nitrates on the serum concentrations of calcium (Ca), phosphorus (P), magnesium (Mg), copper (Cu), iron (Fe) and zinc (Zn) was investigated at the present study. Concurrently, it was evaluated whether the combination of in-feed inclusion of clinoptilolite and of consumption of water naturally contaminated with nitrates, could have any effect on these elements. Two experiments were run simultaneously in two farms each. In the first trial (Trial 1), farm 1 and farm 2 were assigned into two groups according to the nitrate levels in the borehole water. The first group (nitrate group; NG) consisted of the farm 1that had nitrate levels >40 ppm and the second one (control group; CG) of the farm 2 that had water nitrate levels <40 ppm. Similarly, in the second trial (Trial 2) the first group (nitrate – clinoptilolite group; NC) consisted of the farm 3 that had nitrate levels >40p pm and used clinoptilolite as feed additive at the rate of 2.5% of concentrates. The second one (control group; CCG) consisted of the farm 4that had water nitrate levels <40 p pm and did not incorporate clinoptilolite in the ration. The results indicate that the prolonged consumption of water with increased nitrate levels either alone or in combination with clinoptilolite feeding does not have any adverse effects on the serum concentrations of the macro and trace elements evaluated in dairy cattle.
Highly Agglutinative Staphylococcin Therapy for Malignant Pleural Effusions: A Systematic Literature Review and Meta-analysis

Object: The purpose of our study was to evaluate the therapeutic effect and safety of highly agglutinative staphylococcin (HAS) intreatment of malignant pleural effusion (MPE). Materials and Methods: A computerized and manual search was performed of scientific studies published before October2016 in the electronic databases. Three categories of treatment comparisons underwent meta-analysis separately for therapeutic effects and safety. Results: There sults showed that thetherapeutic effect of HAS plus chemotherapy was greater than that of chemotherapy alone (OR, 1.475; 95% CI, 1.14-1.909). The rate of fever was higher in patients treated with HASthan in those treated with lentinan/elemene (OR, 3.791; 95% CI, 1.346-10.687) or chemotherapy (OR, 6.528; 95% CI, 2.331-18.284). The results indicated that the symptom of fever may be a manifestation of HAS stimulating the immune system. Conclusion: HAS combined with chemotherapy has a better therapeutic effect against MPE compared with chemotherapy alone. 1Departments of Pathology and Medical Oncology, The University of Texas MD Anderson Cancer Center, Houston, Texas, USA 2Department of Pathology, Shanxi Cancer Hospital, Taiyuan, Shanxi, China 3Shenyang Xiehe Biopharmaceutical Company, Shenyang, China *Corresponding author Dongfeng Tan, Departments of Pathology and Medical Oncology, The University of Texas MD Anderson Cancer Center, Houston, Texas, USA, e-mail: dtan@mdanderson.org Submitted: 07 Oct 2017; Accepted: 24 Nov 2017; Published: 04 Jan 2018
Impact of water-ph values on the consumption capacity of certain aquatic insects preying on different medical snails

The main aim of this work was to determine the consumption capacity of five aquatic insects (as predators) on four species of medical snails (as preys) tested under four values of pH at a constant and controlling temperature in the laboratory. The predators were represented by adults of two hemipterous species (Limnogeton fieberi Mayr, Sphaerodema urinator Duf.) and three nymph odonatous species (Anax imperator Leach, Crocothemis erythraea Brulle and Ischnura pumilio Charp.). Moreover, the four water-pH values were 5, 7, 9, and 11 at 30°C. On the other hand, the four prey of the medical snails were Bulinus truncates Audouin, Biomphalaria alexandrina Ehrenb, Cleopatra bulimoides Olivier and Melanoides tuberculata Muller. All of individual fauna were collected from the River Nile in Qena. The acidic media were adjusted as a mixture of three acids phosphoric acid acetic acid boric acid. In contrast, the alkalinic solution was prepared by sodium hydroxide. The results illustrate that, the maximum predation occurred under 7 pH and 9 pH at 30°C regardless of the laboratory conditions. It appeared that Bulinus truncates was highly preferable snail species to these predators. Biomphalaria alexandrina which is the intermediate host of Schistosoma mansoni Bilharz, may be the lastly preferable snail species to these predators. The belostomatids (Limnogeton fieberi and Sphaerodema urinator), and the odonats (Anax imperator, Crocothemis erythraea and Ischnura pumilio), could be the highest successful predators on the harmful snails (Bulinus truncates, Melanoides tuberculata, Biomphalaria alexandrina and Cleopatra bulimoides). Therefore, its use should be encouraged to be reared in large numbers and then released in the natural places of snails under 7 to 9 range values of water pH.
Impact of Road Infrastructure on Agricultural Development and Rural Road Infrastructure development programmes in India

Agriculture plays an essential role in the process of economic development of less developed countries like India. Besides providing food to nation, agriculture releases labour, provides saving, contributes to market of industrial goods and earns foreign exchange. Agricultural development is an integral part of overall economic development. Road transport plays an important role in agricultural development. This is because it is the major means of transporting agricultural produce from the farms to the markets as well as to various urban communities. Development of road infrastructure is imperative for agriculture and overall economic growth as also improving the quality of life. Better roads can reduce transaction costs associated with agricultural activities and in so doing have the potential to reduce the costs of acquiring inputs, to increase output prices, and to permit entry into new and more profitable activities. Governments frequently are involved in other dimensions of agricultural activities, and there is an a priori strong case for governments to undertake these investments given the public goods nature of roads. Public investments can play several roles in creating the enabling environment necessary to stimulate agricultural growth.

Respiratory effects of air pollutants among non-smoking traffic policemen: An analytical cross sectional study

Background: Automobile exhaust related air pollution have become a major health hazard. Traffic police personnel, due to their continuous and prolonged exposure are likely to be the worst affected group in this regard. Many studies in the past have documented impaired respiratory function among traffic policemen. Studies from India, exploring the relationship between duration of exposure and respiratory function is necessary. Objective: To compare the pulmonary function parameters between controls and traffic police exposed to air pollutants for variable duration Materials and methods: The study was a community based analytical cross sectional study in Telangana state from August 2012 to November 2013. A total of 120 study participants, including 30 controls and 90 traffic police (30 in each of decadal age groups from 21 to 50 years) were studied. Lung functions were measured by Spirowin. FVC (L), FEV1 (L), FEV1 / FVC ratio, FEF 25 75 (L/Sec) and PEFR (L/Sec) were measured and compared. Results: The absolute and percentage predicted values of FEV1 were higher in control group, compared to traffic police and they have shown gradually decreasing trend with increasing age band which was statistically significant. The mean FVC value and percentage predicted was highest in 21 to 30 age group traffic police and showed gradually declining trend with increasing age band. The other pulmonary function parameters like FEV1/FVC, FEF 25-75 and PEFR have also shown gradually declining trend with increasing age group among traffic police.

Capital Structure and Performance: Empirical Evidence from Vietnam

Capital structure decisions are very important with business because of their impact on firm performance. The purpose of this research was to use panel data regression model to examine the impact of capital structure on 448 Vietnam listed firm’ performance in the period from 2010 to 2016 with 3136 observations. The study used return on assets (ROA) and return on equity (ROE) as the measure of firm’s performance, total debt to total assets (TD) as the measure of capital structure, and control variables as firm size (SIZE), asset tangibility (AS), and liquidity (LQ). The findings indicated that there is a negatively significant impact of total debt (TD) on financial performance measured by ROA, but no significant impact of TD on financial performance measured by ROE. These results may indicate that capital structure decisions have a weak to no impact on Vietnam firm’s performance. ___________________________________________________________________________
Review on The Expected Role of Climate Smart Agriculture on Food System in Ethiopia

This paper reviews various articles, reports and documents on expected role of climate smart agriculture on food system and factors affecting its adoption in Ethiopia. Climate change is global phenomena and is already negatively impacting agricultural production globally and locally. Climate risks to cropping, livestock and fisheries are expected to increase in coming decades, particularly in low-income countries where adaptive capacity is weaker. By 2030, 90% of the world’s major crops, including maize, rice and wheat, will experience reduced or stagnant growth rates as a result of climate change. Climate change is expected to have a greater impact in low-income countries such as Ethiopia because of low numbers of trained people, poor infrastructures and limited economic capability to respond to the challenges. Developing countries such as Ethiopia are less capable of mitigating or adapting to the changes due to their poverty and high dependence on the environment for subsistence. The mainstay of the Ethiopian economy is rain fed agriculture, which is heavily sensitive to climate variability and change. So, this climate change risks require changes in agricultural technologies and approaches to improve the lives of those still locked in food insecurity and poverty and to prevent the loss of gains already achieved. To achieve food security and agricultural development goals, adaptation to climate change will be necessary. Climate-smart agriculture (CSA) is an integrative approach to address the interlinked challenges of food security and climate change. CSA practices in Ethiopia includes proven practical techniques such as mulching, intercropping, conservation agriculture, crop rotation, integrated crop-livestock management, agroforestry, improved grazing and improved water management. CSA has great role in improving food system by addressing food security, reducing poverty and addressing the relationship between climate change and agriculture. Access to information, access to finance and insurance, access to Agricultural input and access to Credit service are some factors that affecting Adoption of CSA. Therefore climate-smart agriculture is essential approach that farmers are supported to adopt to sustain their livelihoods.

Impact of Long Jetties on Shoreline Evaluation (Case Study: Eastern Coast of Bandar Abbas)

The long Jetty at Eastern coast of Bandar Abbas was designed to provide marine access from Bandar Abbas to Hormoz Island, Hormozgan province. Due to local bathymetry, the jetty was designed with relatively large length that may cause significant changes on the hydrodynamic and consequently morphological pattern in coastal area. In this study, tidal currents and wind generated waves were separately simulated using MIKE 21 numerical model in a global scale. The global tidal and wave model were calibrated using available field data and the outputs of the models were applied as the boundary conditions in the main local model. After verification of hydrodynamic model, MIKE 21/3 coupled model was applied to simulate morphological variation around the study area. In the coupled model HD (hydrodynamics), SW (spectral wave) and sediment transport modules were run concurrently and the wave-wave and wave-current interaction has been considered. Shoreline changes due to jetty were assessed and were comparing with mathematical model LITSTP (LITPACK) for more verification of the coupled model. The results of simulations and evaluation of wind effect on the current pattern revealed all three components of wind, tide and wave have significant effects on hydrodynamic regime and therefore, ignoring each component may has a large impact on the sediment transport model. Then wave propagation, wave-induced currents; tidal currents and sedimentation and erosion pattern before and after construction of the Jetty were simulated. The effect of the construction of the jetty on the current regime and sediment transport rate, were also evaluated. The morphological results showed good agreement between the two mentioned models. It can be seen that there is approximately no bed level change before construction of the jetty. In addition, the sedimentation occurs at east side and erosion at west side of jetty after construction of it. The direction of sediment transport is consistent with the dominant waves in the area.
Spinal Interbody Fusion with Unilateral Pedicle Screw Fixation

Transforaminal lumbar interbody fusion (TLIF) was originally described by Harms and Rolinger in 1982 [1]. It has turn out to be one of the ordinary standard techniques for the decompression of the ipsilateral foramen and an appropriate interbody fusion. This procedure is frequently accompanied by the placement of bilateral transpedicular screws in the corresponding segment; this results in immediate rigid segment stabilization that will last while fusion takes places [2,3]. Some authors have proven that excessive stiffness of such a construct can jeopardize the fusion process due to graft resorption that is in hand due to the lack of stress against end plates [4–6].
IMPROVEMENT OF SOIL ENGINEERING PROPERTIES WITH SEWAGE SLUDGE ASH

A laboratory study was conducted to improve the soil engineering properties with sewage sludge ash (SSA) that can be used in different engineering applications. Primarily proctor compaction, grain size distribution, Atterberg limits, and unconfined compressive strength tests were conducted. Proctor compaction test was conducted to determine the optimum moisture content and maximum dry density of soil samples with 0%, 5%, 7.5%, and 10% SSA content. Atterberg limits and grain size distribution tests were conducted to classify the soil. Unconfined compressive strength test was conducted with air-dry curing periods of 0, 10, 14, 28, and 56 days to determine the strength. It was obvious from this study that the addition of SSA improved the soil type as well as the engineering properties. The optimum soil to SSA mixture was a mixture of soil with 7.5% SSA for a curing period of 28 days, which is expected to perform better as engineering materials. A mixture of soil with 5% SSA content for the same curing period could also be used as a viable alternative. The addition of SSA with soil decreased plasticity index that indicated more pronounced reduction in volumetric swelling. wjert, 2019, Vol. 5, Issue 3, 216-233.

Morphology and neurovascular supply of extensor digitorum brevis muscle of the foot in humans: Implications for reconstructive surgeries

Introduction: Extensor digitorum brevis (EDB) is a small muscle present on the dorsum of the foot assisting in the extension of toes. The use of EDB in various plastic surgery procedures has renewed interest of clinicians to study the variations in EDB, its arterial supply and nerve supply. However, a review of literature highlights the paucity of anatomical studies comprehensively describing the morphology of EDB and its variations. The aim was to study the origin, insertion and morphological variants of EDB with emphasis on its arterial supply in embalmed human cadavers, which may have bearing on the use of EDB in various reconstructive surgical procedures. Methods: EDB muscle was carefully dissected to display the attachments, arterial supply and nerve supply, by retracting the tendons of extensor digitorum longus and peroneus tertius muscles. Results: EDB demonstrated many variations in its origin and insertion, had additional bellies and also had additional tendinous slips connecting its muscle bellies and having attachment over fascia covering the dorsal interossei and the metatarsals. Extensor hallucis brevis was the most prominent belly. In 13 cases, two lateral tarsal arteries supplied the muscle. Variations in the origin of dorsalis pedis artery were also observed. Accessory deep peroneal nerve was found to supply the muscle in addition to the lateral terminal branch of deep peroneal nerve in three specimens. In view of wide usage of EDB for clinical procedures, the knowledge of variations in its morphology, especially arterial supply and nerve supply is essential.

Comparative Efficacy of Physico-Chemical and Biological Treatments on Seed Germination and Mycoflora of Sesamum indicum L

Sesamum indicum L. is among the oldest oilseed crops of the world. Its production and storage are affected by a vast group of microbes, primarily the fungi. The present investigations were conducted with the aim to address agronomic performance traits of seed quality. Many deteriorative microbes, particularly fungi, create problems in its production and storage. So, the present study was designed to evaluate the effect of different treatments to increase the germination and inhibit the mycoflora of sesame seeds. Sesame seeds were subjected to various treatments, including, thermotherapy (by incubation at 50oC, 60oC and 70oC), application of fungicides (Mancozeb, Thiophante Methyl and Carbendazim), plant extracts (Melia azedarach, Cannabis sativa and Pongamia pinnata) and bioagents (Trichoderma viride, T. harzianum, Pseudomonas fluorescens, Bacillus subtilis and Saccharomyces cerevisiae). Seed germination was tested by following the protocol of International Seed Testing Association. Antifungal activity was tested by poisoned food technique. The results revealed that the germination increased effectively, due to thiophanate methyl up to 46%, followed by Cannabis sativa (37%). Thermotherapy increased germination (28%) at 60oC but caused harmful effect on seeds at 70oC, whereas, Pseudomonas fluorescens, Bacillus subtilis and Trichoderma harzianum increased germination up to 40%. Out of 7 fungi tested against fungicides and plant extracts, 4 fungi, namely Aspergillus flavus, Aspergillus niger, Fusarium oxysporum and Penicillium egyptiacum, were inhibited up to 100% by Carbendazim and Thiophanate Methyl, while Mancozeb inhibited Penicillium egyptiacum (100%), only. Cannabis sativa inhibited Alternaria alternata (100%) and Rhizopus oryzae (55.6%). Overall treatment with fungicides gave best results but they were not eco-friendly. So, this study recommends the use of plant extracts and bioagents, which may increase seed germination and inhibit seed-borne fungi without any harmful effect.
