The trial was conducted at the research block of Crop Improvement, GBPUAT, Hill Campus, Ranichauri using randomized block design (RBD) to characterize finger millet germplasm for morphological characters viz., plant height, flag leaf length, number of tiller plant-1, number of finger ear-1, ear length, no. of grain finger-1, no. of grain ear-1 and grain yield plant-1. Among all germplasms, number of finger ear-1, number of grain finger-1 and grain yield plant-1(g) had recorded highest in VL 149 which were 9.96, 150.66, 2.63 g respectively. The germplasm GEC 1406 attained lowest plant height (75.89 cm), GEC 961 had recorded higher flag leaf length (40.96 cm), GEC 268 had recorded maximum number of tiller plant-1 (3.30), GEC 199 had recorded higher ear length (9.20 cm), GEC 1044 had recorded maximum number of grain ear-1 (663) among all germplasm of finger millet. This study is helpful to identify superior germplasm so they can be used for further finger millet crop improvement programs.

Detailed analysis of five gas emission craters (GEC) found in the north of West Siberia is presented. Remote sensing data used in the study is verified by field surveys. Previous studies show that all of the GECs were preceded by mounds 2 to 6 m high and 20 to 55 m in diameter. GECs initially were 20–25 m in diameter, which increased in the first years of their existence. GECs are found in various environmental (shrublands or moss-grass tundra) and geomorphic (river valley, terrace, slopes) conditions. The objective of the paper is to identify common and differing geomorphologic and environmental characteristics of all the five GEC, and their mound-predecessors. The study is based on a compilation of DSMs before and after the GEC formation using very high-resolution satellite imagery stereo pairs compared to ArcticDEM project data. Diversity of terrain and environmental settings along with rather a narrow range of GEC and mound-predecessor morphometric parameters allows concluding that the mechanism of GEC formation is most likely similar for all the GEC and is controlled rather by internal geologic and cryolithologic structure than by any surface properties.

In arid and semi-arid lands like Iran water is scarce, and not all the wastewater can be treated. Hence, groundwater remains the primary and the principal source of water supply for human consumption. Therefore, this study attempted to spatially assess the groundwater potential in an aquifer in a semi-arid region of Iran using geographic information systems (GIS)-based statistical modeling. To this end, 75 agricultural wells across the Marvdasht Plain were sampled, and the water samples’ electrical conductivity (EC) was measured. To model the groundwater quality, multiple linear regression (MLR) and principal component regression (PCR) coupled with elven environmental parameters (soil-topographical parameters) were employed. The results showed that that soil EC (SEC) with Beta = 0.78 was selected as the most influential factor affecting groundwater EC (GEC). CaCO3 of soil samples and length-steepness (LS factor) were the second and third effective parameters. SEC with r = 0.89 and CaCO3 with r = 0.79 and LS factor with r = 0.69 were also characterized for PC1. According to performance criteria, the MLR model with R2 = 0.94, root mean square error (RMSE) = 450 µScm−1 and mean error (ME) = 125 µScm−1 provided better results in predicting the GEC. The GEC map indicated that 16% of the Marvdasht groundwater was not suitable for agriculture. It was concluded that GIS, combined with statistical methods, could predict groundwater quality in the semi-arid regions.

Transcapillary adenosine transport was studied in isolated guinea pig and rat hearts perfused with a colloid-free solution. High-performance liquid chromatography techniques were used to measure adenosine concentration of venous and interstitial (epicardial surface) fluid during steady-state perfusion with various concentrations of adenosine. A mathematical model was used to analyze these data to obtain estimates of the following parameters of transcapillary adenosine transport: PSg, permeability-surface area product for adenosine movement through interendothelial cell channels; PSecl, permeability-surface area product for adenosine movement through the luminal plasma membrane of endothelial cells; and Gec, clearance rate constant for endothelial cell metabolism and/or sequestration of adenosine. In both guinea pig and rat hearts, PSg was estimated to be less than or equal to 3 ml.min-1.g-1. Estimates of PSecl and Gec of guinea pig hearts (7.2 +/- 0.4 and 230 +/- 157 ml.min-1.g-1) were significantly less than those of rat hearts (66 +/- 11 and 2,490 +/- 1,360 ml.min-1.g-1). That PSecl is greater than PSg in both species indicates that endothelial cells represent an important pathway for transcapillary adenosine transport. That Gec is much greater than PSecl in both species implies that endothelial cells act as a sink for adenosine from surrounding areas. Our results indicate that endothelium is a stronger sink for adenosine in rat hearts than in guinea pig hearts. Inosine infusion (10(-4)M) had little effect on the estimated PSecl and Gec in guinea pig hearts but reduced these parameters several-fold in rat hearts, suggesting that different transport mechanisms for adenosine exist in endothelia of guinea pig and rat hearts.

Abstract Suitability of isotope-selective nondispersive infrared spectrometry (IRIS) for evaluation of [13C]octanoic acid gastric-emptying breath test was assessed and compared with standard isotope ratio–mass spectrometry (IRMS). The estimated bias of IRMS and IRIS measurements of baseline-corrected 13CO2exhalation amounted to ± 0.1 and ± 0.6 Δδ values (n = 360), respectively. In breath tests performed on 60 diabetic patients, the gastric emptying parameters were calculated by nonlinear regression analysis of the time course of 13CO2exhalation: half-emptying time (t1/2,breath, 90 ± 39 min), lag phase (tlag,breath, 34 ± 27 min), and gastric emptying coefficient (GEC, 2.9 ± 0.5). A reasonable linear correlation was found between the two methods (y = IRIS, x = IRMS) with respect to Δδ values (y = 0.35 + 0.92x, r = 0.985, Sy|x = ±0.6, n = 1116) and a rather good agreement of the computed gastric emptying parameters was obtained (t1/2,breath: y = 0.99x + 4.06, Sy|x = ±6.3; tlag,breath: y = 0.97x + 0.96, Sy|x = ±3.4; GEC: y = 0.97x − 0.01, Sy|x = ±0.09).

101 Background: Inspired by the promising results seen in patients (pts) with chemo-resistant metastatic colorectal cancer we evaluated a biweekly schedule of cetuximab (cet) and irinotecan (iri) (Cetiri) (Pfeiffer et al. Ann Oncol 2008) in platinum resistant GEC. Methods: We treated and evaluated 111 consecutive pts with histological verified GEC adenocarcinoma and documented failure to first-line platinum-based treatment. Pts received cet 500 mg/m2 and iri 180 mg/m2 day 1 every 2nd week until progression or unacceptable toxicity. Toxicity was evaluated according to NCI-CTCAE v. 3.0. Response rate (RR) was evaluated according to RECIST v. 1.0 every 8th week. Clinical parameters and blood samples at baseline were analyzed in order to find prognostic and predictive values for prolonged overall survival (OS). Results: Pts were included from December 2007 to August 2010. Median age was 61 years (range 33-80). Performance status (PS) was 0-1 in 95 % of the pts. Thirty-six (46%) pts had more than two organs involved. Median number of courses was 8 (1-46). RR was 14% (2 CR, 13 PR) and 63% had stable disease for at least 2 months. Median PFS and OS were 3.2 months (CI 2-4) and 5.6 months (CI: 5-7) respectively. Seventy six (68%) pts had treatment induced skin toxicity, rash. In a univariate analysis PS 0-1, normal baseline haematology and skin rash was associated with significantly increased survival. These parameters retained significance in a multivariate analysis. One patient had a curative resection after end of treatment and four pts are still alive. Conclusions: Biweekly Cetiri is a convenient and well-tolerated second-line (SL) regimen in pts with GEC adenocarcinoma. Good performance status, normal baseline and development of skin rash indicate increased survival. Based on our findings biweekly Cetiri can be recommended as SL treatment to GEC pts in a good PS. Further studies into the role of rash are warranted.

Abstract. Non-electrified clouds in the fair-weather part of the Global Electric Circuit (GEC) reduce conductivity because of the limited mobility of charge due to attachment to cloud water droplets, effectively leading to a loss of ions. A high-resolution GEC model, which numerically solves the Poisson equation, is used to show that in the fair-weather region currents partially flow around non-electrified clouds, with current divergence above the cloud, and convergence below the cloud. An analysis of this effect is presented for various types of non-electrified clouds, i.e. for different altitude extents, and for different horizontal dimensions, finding that the effect is most pronounced for high clouds with a diameter below 100 km. Based on these results, a method to calculate column and global resistance is developed that can account for all cloud sizes and altitudes. The CESM1(WACCM) Earth System Model as well as ISCCP cloud data are used to calculate the effect of this phenomenon on global resistance. From CESM1(WACCM), it is found that when including non-electrified clouds in the fair-weather estimate of resistance the global resistance increases by up to 73%, depending on the parameters used. Using ISCCP cloud cover leads to an even larger increase, which is likely to be overestimated because of time-averaging of cloud cover. Neglecting current divergence/convergence around small clouds overestimates global resistance by up to 20%, whereas the method introduced by previous studies underestimates global resistance by up to 40%. For global GEC models, a conductivity parametrization is developed to account for the current divergence/convergence phenomenon around non-electrified clouds. Conductivity simulations from CESM1(WACCM) using this parametrization are presented.

Abstract. Clouds in the fair weather return path of the global electric circuit (GEC) reduce conductivity because of the limited mobility of charge due to attachment to cloud water droplets, effectively leading to a loss of ions. A high-resolution GEC model, which numerically solves the current continuity equation in combination with Ohm's law, is used to show that return currents partially flow around clouds, with current divergence above the cloud and convergence below the cloud. An analysis of this effect is presented for various types of clouds, i.e., for different altitude extents and for different horizontal dimensions, finding that the effect is most pronounced for high clouds with a diameter below 100 km. Based on these results, a method to calculate column and global resistance is developed that can account for all cloud sizes and altitudes. The CESM1(WACCM) (Community Earth System Model – Whole Atmosphere Community Climate Model) as well as ISCCP (International Satellite Cloud Climatology Project) cloud data are used to calculate the effect of this phenomenon on global resistance. From CESM1(WACCM), it is found that when including clouds in the estimate of resistance the global resistance increases by up to 73%, depending on the parameters used. Using ISCCP cloud cover leads to an even larger increase, which is likely to be overestimated because of time averaging of cloud cover. Neglecting current divergence/convergence around small clouds overestimates global resistance by up to 20% whereas the method introduced by previous studies underestimates global resistance by up to 40%. For global GEC models, a~conductivity parameterization is developed to account for the current divergence/convergence phenomenon around clouds.

High velocity impact analysis of natural fiber reinforced composites is essential as the trend is focused towards the development of light weight, environment-friendly, non-corrosive and economical materials. At present, the defence, aerospace and automobile sectors are using synthetic fiber composites which are expensive and non-eco-friendly. In the present study ballistic impact of jute-epoxy (JEC), glass-epoxy (GEC), jute-epoxy-rubber (JERC) sandwich composites are simulated with different thickness (1, 2 and 3 mm) and velocity variations (100, 200 and 300m/s) using Finite Element analysis software. Although different approaches to the analysis of the effect response of composite structures are available, numerical modeling is based on strict constitutive models is often preferred because it can provide valuable detailed information about the spatial and temporal distribution of damage during the impact. The ballistic parameters such as energy absorption, ballistic limit and fracture behaviors are predicted. The composite is made of 8 noded linear brick elements and the bullet/projectile is modeled as a discrete rigid element in which deformation behavior, energy absorption and penetration behaviors obtained are clearly represented. The simulation results predicted match well with the analytical results obtained. Among all the combination of the materials simulated, the sandwiches have better ballistic qualities. Energy absorption of sandwich (JERC) was found 67 percentage higher than GEC and 56 percentage higher than JEC laminate. In future, these materials can be the alternative materials for defence sector for bullet proofing.

Streszczenie:
Les incertitudes épistémiques peuvent être réduites via des études supplémentaires (mesures labo, in situ, ou modélisations numériques, etc.). Nous nous concentrons ici sur celle "paramétrique" liée aux difficultés à évaluer quantitativement les paramètres d’entrée du modèle utilisé pour l’analyse des aléas géotechniques. Une stratégie de gestion possible est l’analyse de sensibilité, qui consiste à identifier la contribution (i.e. l’importance) des paramètres dans l’incertitude de l’évaluation de l’aléa. Des approches avancées existent pour conduire une telle analyse. Toutefois, leur application au domaine des aléas géotechniques se confronte à plusieurs contraintes : 1. le coût calculatoire des modèles numériques (plusieurs heures voire jours) ; 2. les paramètres sont souvent des fonctions complexes du temps et de l’espace ; 3. les données sont souvent limitées, imprécises voire vagues. Dans cette thèse, nous avons testé et adapté des outils statistiques pour surmonter ces limites. Une attention toute particulière a été portée sur le test de faisabilité de ces procédures et sur la confrontation à des cas réels (aléas naturels liés aux séismes, cavités et glissements de terrain)
Importance ranking of parameter uncertainties in geo-hazard assessments Epistemic uncertainty can be reduced via additional lab or in site measurements or additional numerical simulations. We focused here on parameter uncertainty: this corresponds to the incomplete knowledge of the correct setting of the input parameters (like values of soil properties) of the model supporting the geo-hazard assessment. A possible option tomanage it is via sensitivity analysis, which aims at identifying the contribution (i.e. the importance) of the different input parameters in the uncertainty on the final hazard outcome. For this purpose, advanced techniques exist, namely variance-basedglobal sensitivity analysis. Yet, their practical implementation faces three major limitations related to the specificities of the geo-hazard domain: 1. the large computation time cost (several hours if not days) of numerical models; 2. the parameters are complex functions of time and space; 3. data are often scarce, limited if not vague. In the present PhD thesis, statistical approaches were developed, tested and adapted to overcome those limits. A special attention was paid to test the feasibility of those statistical tools by confronting them to real cases (natural hazards related to earthquakes, cavities and landslides)

The objective of this work of thesis is the refined estimations of source parameters. To such a purpose we used two different approaches, one in the frequency domain and the other in the time domain. In frequency domain, we analyzed the P- and S-wave displacement spectra to estimate spectral parameters, that is corner frequencies and low frequency spectral amplitudes. We used a parametric modeling approach which is combined with a multi-step, non-linear inversion strategy and includes the correction for attenuation and site effects. The iterative multi-step procedure was applied to about 700 microearthquakes in the moment range 1011-1014 N•m and recorded at the dense, wide-dynamic range, seismic networks operating in Southern Apennines (Italy). The analysis of the source parameters is often complicated when we are not able to model the propagation accurately. In this case the empirical Green function approach is a very useful tool to study the seismic source properties. In fact the Empirical Green Functions (EGFs) consent to represent the contribution of propagation and site effects to signal without using approximate velocity models. An EGF is a recorded three-component set of time-histories of a small earthquake whose source mechanism and propagation path are similar to those of the master event. Thus, in time domain, the deconvolution method of Vallée (2004) was applied to calculate the source time functions (RSTFs) and to accurately estimate source size and rupture velocity. This technique was applied to 1) large event, that is Mw=6.3 2009 L’Aquila mainshock (Central Italy), 2) moderate events, that is cluster of earthquakes of 2009 L’Aquila sequence with moment magnitude ranging between 3 and 5.6, 3) small event, i.e. Mw=2.9 Laviano mainshock (Southern Italy).

In recent years, thanks to the technological advances, electromagnetic methods for non-invasive shallow subsurface characterization have been increasingly used in many areas of environmental and geoscience applications. Among all the geophysical electromagnetic methods, the Ground Penetrating Radar (GPR) has received unprecedented attention over the last few decades due to its capability to obtain, spatially and temporally, high-resolution electromagnetic parameter information thanks to its versatility, its handling, its non-invasive nature, its high resolving power, and its fast implementation. The main focus of this thesis is to perform a dielectric site characterization in an efficient and accurate way studying in-depth a physical phenomenon behind a recent developed GPR approach, the so-called early-time technique, which infers the electrical properties of the soil in the proximity of the antennas. In particular, the early-time approach is based on the amplitude analysis of the early-time portion of the GPR waveform using a fixed-offset ground-coupled antenna configuration where the separation between the transmitting and receiving antenna is on the order of the dominant pulse-wavelength. Amplitude information can be extracted from the early-time signal through complex trace analysis, computing the instantaneous-amplitude attributes over a selected time-duration of the early-time signal. Basically, if the acquired GPR signals are considered to represent the real part of a complex trace, and the imaginary part is the quadrature component obtained by applying a Hilbert transform to the GPR trace, the amplitude envelope is the absolute value of the resulting complex trace (also known as the instantaneous-amplitude). Analysing laboratory information, numerical simulations and natural field conditions, and summarising the overall results embodied in this thesis, it is possible to suggest the early-time GPR technique as an effective method to estimate physical properties of the soil in a fast and non-invasive way.

Basically, if the acquired GPR signals are considered to represent the real part of a complex trace, and the imaginary part is the quadrature component obtained by applying a Hilbert transform to the GPR trace, the amplitude envelope is the absolute value of the resulting complex trace (also known as the instantaneous-amplitude). Analysing laboratory information, numerical simulations and natural field conditions, and summarising the overall results embodied in this thesis, it is possible to suggest the early-time GPR technique as an effective method to estimate physical properties of the soil in a fast and non-invasive way.

Streszczenie:
Grinding is a critical manufacturing process and is often the only alternative when producing precision components or when machining brittle materials such as ceramics. Characterizing and modeling the surface finish in the grinding process is a difficult task due to the stochastic nature of the size, shape and spatial distribution of abrasive grains that make up the surface of grinding wheels. Since the surface finish obtained in grinding is a direct function of the wheel surface topography, which is conditioned by a single point dressing process, understanding the effects of dressing parameters on the wheel topography is essential. Therefore, the main objectives of this thesis are: 1) to experimentally characterize the three-dimensional surface topography of a conventional grinding wheel including attributes such as the abrasive grain height distribution, grain geometry and spacing parameters and their respective statistical distributions, 2) to determine the effects of single point dressing conditions on the three-dimensional wheel surface topography parameters and their distributions, 3) to model and simulate the three-dimensional wheel surface topography, and 4) to experimentally validate the wheel topography model. In this research, new and existing characterization methods are used to characterize the wheel surface and the individual abrasive grains. The new techniques include the use of X-ray micro-tomography (μCT) to obtain a better understanding of the grinding wheel's internal micro-structure, and a focus variation based optical measurement method and scanning electron microscopy to characterize previously ignored attributes such as the number of sides and aspect ratio of individual grains. A seeded gel (SG) vitrified bond conventional grinding wheel is used in the study. A full factorial design of single point wheel dressing experiments is performed to investigate the effects infeed and lead dressing parameters on the grinding wheel surface topography. A custom wheel indexing apparatus is built to facilitate precision relocation of the grinding wheel surface to enable optical comparison of the pre- and post-dressing wheel surface topography to observe wheel surface generation mechanisms such as macro-fracture and grain dislodgement. Quantitative descriptions of how each dressing parameter affects the wheel surface characteristics are given in terms of the wheel surface roughness amplitude parameters (Sp, Ssk, Sku) and areal and volume parameters (Spk, Sk, Vmp, Vmp, Vvc, Smr1) derived from the bearing area curve. A three-dimensional wheel topography simulation model that takes as input the abrasive grain height distribution and the statistical distributions for the various abrasive grain geometry parameters is developed and experimentally validated. The results of wheel characterization studies show that the actual abrasive grain height distribution in the SG wheel follows a beta distribution. The μCT work shows that the abrasives are polyhedral in shape, as opposed to the spherical or conical shapes commonly assumed in grinding literature. Grain spacing is found to follow a beta distribution while the number of sides of the grain and the grain aspect ratio are found to follow the gamma and the Weibull distribution, respectively. The results of the dressing study show that the lead dressing parameter has the strongest effect on wheel topography. Using statistical distributions for the key parameters (e.g. grain height, number of sides, grain spacing), a stochastic three-dimensional model is developed to simulate the wheel surface topography under different dressing conditions. The resulting model is shown to yield realistic results compared to existing models mainly due the fact that additional abrasive grain geometry parameters and more realistic assumptions of the different grain attributes are used in the model. It is shown that the model follows the overall wheel surface topography trends during dressing but has difficulty in accurately simulating some of the wheel characteristics under specific dressing conditions. The thesis then concludes with a summary of the main findings and possible future research avenues including extending the model to rotary dressing and simulation of wheel-workpiece interaction.

Streszczenie:
Power transformers are a key element in the transmission and distribution of electrical energy and as such need to be highly reliable and efficient. In power system networks, transformer core saturation can cause system voltage disturbances or transformer damage or accelerate insulation ageing. Low frequency switching transients such as ferroresonance and inrush currents, and increasingly what is now known as geomagnetic induce currents (GIC), are the most common phenomena to cause transformer core saturation. This thesis describes extensive simulation studies carried out on GIC and switching ferroresonant transient phenomena. Two types of transformer model were developed to study core saturation problems; one is the mathematical transformer magnetic circuit model, and the other the ATPDraw transformer model. Using the mathematical transformer magnetic circuit model, the influence of the transformer core structure on the magnetising current has been successfully identified and so have the transformers' responses to GIC events. By using the ATPDraw transformer model, the AC system network behaviours under the influence of the DC bias caused by GIC events have been successfully analysed using various simulation case studies. The effects of the winding connection, the core structure, and the network parameters including system impedances and transformer loading conditions on the magnetising currents of the transformers are summarised. Transient interaction among transformers and other system components during energisation and de-energisation operations are becoming increasingly important. One case study on switching ferroresonant transients was modelled using the available transformer test report data and the design data of the main components of the distribution network. The results were closely matched with field test results, which verified the simulation methodology. The simulation results helped establish the fundamental understanding of GIC and ferroresonance events in the power networks; among all the influential parameters identified, transformer core structure is the most important one. In summary, the five-limb core is easier to saturate than the three-limb transformer under the same GIC events; the smaller the side yoke area of the five-limb core, the easier it will be to saturate. More importantly, under GIC events a transformer core could become saturated irrespective of the loading condition of the transformer.

Neural substrate for changes in neuromotor skills of typically developing children involves the complex and organized maturation of underlying brain structures. This article gives an overview of the changes that occur in motor function, as children get older and those aspects of central nervous development which may form the neural substrates of motor function development. It describes those TMS evoked parameters, related to the motor system, that have been studied in both typically developing children and in those who have suffered perinatal insults to the central nervous system. TMS has its limitations and is especially useful when used in combination with other neurophysiological modalities. The focus for future studies should be on correlating TMS evoked parameters with behavioural measures in typically developing children and explanation of the neural substrates of the motor abnormalities in children with perinatal insults and developmental disabilities.

This text is grounded in Barba’s lived experience as a dancer trained in Quito and Brussels. He begins by examining an instance in which a dance is said to look old-fashioned even though it has been recently created. When this judgment occurs across continental boundaries, Barba notes that from a Eurocentric and historicist perspective, working outside the parameters of the so-called centers for contemporary dance can be perceived as traveling back in time. This dismissal of a particular dance, or even of an entire dance tradition, as not really contemporary when identified from within the borders of European modernity is examined and questioned. To navigate through the varied hetero-temporalities enacted in and through different geo-cultural locations, the concepts of historicism (Dipesh Chakrabarty), denial of coevalness (Johannes Fabian), and temporal discrimination (Rolando Vázquez) are applied to this situation of dance and danced reenactment.

This chapter deals with the signals produced by particles that are being absorbed in a calorimeter. The calorimeter response is defined as the average signal produced per unit energy deposited in this absorption process, for example in terms of picoCoulombs per GeV. Defined in this way, a linear calorimeter has a constant response. Typically, the response of the calorimeter depends on the type of particle absorbed in it. Also, most calorimeters are non-linear for hadronic shower detection. This is the essence of the so-called non-compensation problem, which has in practice major consequences for the performance of calorimeters. The origins of this problem, and its possible solutions are described. The roles of the sampling fraction, the sampling frequency, the signal integration time and the choice of the absorber and active materials are examined in detail. Important parameters, such as the e/mip and e/h values, are defined and methods to determine their value are described.

This volume is about how human languages get to be the way they are, why they are different from one another in some ways and not others, and why they change in the ways that they do. Given that language is a universal creation of the human mind, the puzzle is why there are different languages at all, why we don’t all speak the same language. And while there is considerable variation, there are ways in which grammars show consistent patterns. The solution to these puzzles, the author proposes, is a constructional one. Grammars consist of constructions that carry out the function of expressing universal conceptual structure. While there are in principle many different ways of accomplishing this task, the constructions that languages actually use are under pressure to reduce complexity. The result is that there is constructional change in the direction of less complexity, and grammatical patterns emerge that reflect conceptual universals. The volume consists of three parts. Part I establishes the theoretical foundations: situating universals in conceptual structure, formally defining constructions, and characterizing constructional complexity. Part II explores variation in argument structure, grammatical functions, and A′ constructions, drawing on data from a variety of languages, including English and Plains Cree. Part III looks at constructional change, focusing primarily on English and German. The study ends with some observations and speculations on parameter theory, analogy, the origins of typological patterns, and Greenbergian ‘universals’.

Introduction: Cervical cancer has a high incidence in developing countries including India. Brachytherapy (BT) is an important component in the curative management of carcinoma of the cervix, and significantly improves survival. In gynaecologic BT, correlation between the radiation dose and the normal tissue effects have been assessed using point doses. Since 1985, these points have been defined in the international commission of radiation units and measurements (ICRU-38) report. However GEC-ESTRO recommended volume based treatment planning in their respective series (I-IV). For cervical cancer BT, the correlation of ICRU point doses and volume based treatment planning is investigational till date. Analysis becomes feasible when cross sectional image-based treatment planning for BT using computerized tomography (CT) or magnetic resonance imaging (MRI) is utilised as per GEC-ESTRO recommendation. Methods: It is a retrospective pilot study includes patients (pts.) of carcinoma cervix treated with high dose rate (HDR) BT 9 Gy in 2 fractions 1 week apart. All volume based dosimeteric parameters regarding high risk clinical target volume (HRCTV), intermediate risk clinical target volume (IRCTV) like D90, D100 and for organ at risk (OAR) D 0.1 cc, D 1.0 cc and D 2.0 cc were delineated and dose coverage was analysed in point dose based planning. Results: We have analysed twenty pts. of squamous cell carcinoma (SCC) cervix. The median age was 52 yrs. (41-65 yrs), stage II B 10 pts. & III B 10 pts. The mean value of D90 & D100 in HRCTV during I and II session were 8.64, 6.75 and 5.76, 4.36 Gy respectively. Same values for IRCTV were 6.31, 4.91 and 3.68, 3.15 Gy respectively. Analysis of OARs demonstrated that mean dose received by 0.1, volume of bladder during I and II session received 10.68, 9.47, by 1 cc volume 8.39, 7.57 and by 2 cc volume 6.84, 6.21 Gy respectively. The mean dose received by 0.1 cc of rectum were 11.59, 10.12, by 1 cc volume 9.53, 8.19 and by 2 cc volume 7.76, 6.81 Gy respectively. In point based analysis mean dose delivered to bladder point during I and II session were 5.63, 6.02 and to rectum point were 5.98, 5.46 Gy respectively. Doses to 0.1 cc volume of bladder and rectum were higher in volume based BT as compared to point based BT in respective fractions. Conclusion: Both HRCTV and IRCTV had better dose coverage in 1st fraction as compared to 2nd fraction. Point doses to bladder and rectum is underestimated in point based (ICRU-38) BT. We need more number of pts in prospective randomized trial for more consistent result.

Streszczenie:
Injecting a polymer solution into a porous medium significantly increases the modeling complexity, compared to model a polymer bulk solution. Even if the polymer solution is injected at a constant rate into the porous medium, the polymers experience different flow regimes in each pore and pore throat. The main challenge is to assign a macroscopic porous media “viscosity” to the fluid which can be used in Darcy law to get the correct relationship between the injection rate and pressure drop. One can achieve this by simply tabulating experimental results (e.g., injection rate vs pressure drop). The challenge with the tabulated approach is that it requires a huge experimental database to tabulate all kind of possible situations that might occur in a reservoir (e.g., changing temperature, salinity, flooding history, permeability, porosity, wettability etc.). The approach presented in this report is to model the mechanisms and describe them in terms of mathematical models. The mathematical model contains a limited number of parameters that needs to be determined experimentally. Once these parameters are determined, there is in principle no need to perform additional experiments.

To reduce financial risk and N losses to the environment, fertilization methods are needed that improve NUE and increase the quality of wheat. In the literature, ample attention is given to grid-based and zone-based soil testing to determine the soil N available early in the growing season. Plus, information is available on in-season N topdressing applications as a means of improving GPC. However, the vast majority of research has focused on wheat that is grown under N limiting conditions in sub-humid regions and irrigated fields. Less attention has been given to wheat in dryland that is water limited. The objectives of this study were to: (1) determine accuracy in determining GPC of HRSW in Israel and SWWW in Oregon using on-combine optical sensors under field conditions; (2) develop a quantitative relationship between image spectral reflectance and effective crop physiological parameters; (3) develop an operational precision N management procedure that combines variable-rate N recommendations at planting as derived from maps of grain yield, GPC, and test weight; and at mid-season as derived from quantitative relationships, remote sensing, and the DSS; and (4) address the economic and technology-transfer aspects of producers’ needs. Results from the research suggest that optical sensing and the DSS can be used for estimating the N status of dryland wheat and deciding whether additional N is needed to improve GPC. Significant findings include: 1. In-line NIR reflectance spectroscopy can be used to rapidly and accurately (SEP <5.0 mg g⁻¹) measure GPC of a grain stream conveyed by an auger. 2. On-combine NIR spectroscopy can be used to accurately estimate (R² < 0.88) grain test weight across fields. 3. Precision N management based on N removal increases GPC, grain yield, and profitability in rainfed wheat. 4. Hyperspectral SI and partial least squares (PLS) models have excellent potential for estimation of biomass, and water and N contents of wheat. 5. A novel heading index can be used to monitor spike emergence of wheat with classification accuracy between 53 and 83%. 6. Index MCARI/MTVI2 promises to improve remote sensing of wheat N status where water- not soil N fertility, is the main driver of plant growth. Important features include: (a) computable from commercial aerospace imagery that include the red edge waveband, (b) sensitive to Chl and resistant to variation in crop biomass, and (c) accommodates variation in soil reflectance. Findings #1 and #2 above enable growers to further implement an efficient, low cost PNM approach using commercially available on-combine optical sensors. Finding #3 suggests that profit opportunities may exist from PNM based on information from on-combine sensing and aerospace remote sensing. Finding #4, with its emphasis on data retrieval and accuracy, enhances the potential usefulness of a DSS as a tool for field crop management. Finding #5 enables land managers to use a DSS to ascertain at mid-season whether a wheat crop should be harvested for grain or forage. Finding #6a expands potential commercial opportunities of MS imagery and thus has special importance to a majority of aerospace imaging firms specializing in the acquisition and utilization of these data. Finding #6b on index MCARI/MVTI2 has great potential to expand use of ground-based sensing and in-season N management to millions of hectares of land in semiarid environments where water- not N, is the main determinant of grain yield. Finding #6c demonstrates that MCARI/MTVI2 may alleviate the requirement of multiple N-rich reference strips to account for soil differences within farm fields. This simplicity will be less demanding of grower resources, promising substantially greater acceptance of sensing technologies for in-season N management.

Streszczenie:
CGE models are utilized for the evaluation of trade policy reforms, yet they are typically highly aggregated, limiting their usefulness to trade negotiators interested in impacts at the tariff line. Partial Equilibrium (PE) models used for disaggregate analysis lack the benefits of an economy-wide analysis required to examine the overall impact of trade policy reforms. This suggests the need for a PE-GE, nested modeling framework to support trade policy analysis. In this paper, we develop a PE model that captures international trade, domestic consumption and output, using CET and CES structures, market clearing conditions and price linkages, nested within the standard GTAP Model. In addition, we extend the welfare decomposition of Huff and Hertel (2001) to this PE-GE model to contrast the sources of welfare gain among models. To illustrate the value-added of this model, we examine the impact of multi-lateral tariff liberalization on the Indian economy, with special focus on the auto sector, using PE, GE and PE-GE models. The PE model does not predict the change in overall size and price level for the industry well, while the GE model underestimates the aggregate welfare gain due to tariff averaging. It also fails to account for the change in industry composition resulting from trade reform. These findings are robust to wide variation in model parameters. We conclude that the linked model is superior to both the GE and PE counterparts.
