A Review On The Science Of Growing Crops Without Soil ( Soilless Culture ) – A Novel Alternative For Growing Crops

Soil-based agriculture is facing some major challenges with the advent of civilization all over the world, such as decrease per capita land availability. Apart from this, due to rapid urbanization and industrialization as well as threats from climate change and its related adverse effect, the land cultivation is going to further facing challenging threats. Under such circumstances, in the near future it becomes intricate to feed the entire population using the production from soil field system. Naturally, soil-less culture is becoming more relevant in the present scenario, to cope-up with these challenges. ―Soilless Culture‖ is the growing of plants that imitate soilbase gardening by using many kinds of growing media as for example inorganic substance, organic substance and synthetic substrates. Soilless culture is the fastest growing sector of agriculture, and it could be impetus to food production in the future. The industry is expected to grow exponentially also in future, as conditions of soil growing becoming difficult. The application of a soilless culture system using artificial substrates would result in efficient and effective use of water and fertilizers and minimize the use of chemicals for pest and disease control. Plants grown in soil less culture has consistently superior quality, high yield, rapid harvest, and high nutrient content. But in case of under developing countries there is a lack of its customary acquaintance and poor dissemination of its available technologies. For popularization of soilless culture at global level, it is very imperative to provide scientific proven technology to gardeners and create mass awareness in potential areas at global level.
Functional hemispheric asymmetries in humans: electrophysiological evidence from preterm infants

In recent years, magnetic resonance imaging has allowed researchers to individuate the earlier morphological development of the right hemisphere compared with the left hemisphere during late‐gestational development. Anatomical asymmetry, however, does not necessarily mean functional asymmetry, and whether the anatomical differences between hemispheres at this early age are paralleled by functional specialisations remains unknown. In this study, the presence of lateralised electrical brain activity related to both pitch detection and discrimination was investigated in 34 prematurely‐born infants [24–34 gestational weeks (GWs)] all tested at the same post‐conceptional age of 35 weeks. By means of a frequency–change oddball experimental paradigm, with ‘standard’ tones at 1000 Hz (P = 90%) and ‘deviant’ tones at 2000 Hz (P = 10%), we were able to record higher right event‐related potential activity in the interval windows between 350 and 650 ms after stimulus onset. An explorative hierarchical cluster analysis confirmed the different distribution of the hemispheric asymmetry score in newborns < 30 weeks old. Here, we show electrophysiological evidence of the early functional right lateralisation for pitch processing (detection and discrimination) arising by 30 GWs, but not before, in preterm newborns despite the longer environmental sensorial experience of newborns < 30 GWs. Generally, these findings suggest that the earlier right structural maturation in foetal epochs seems to be paralleled by a right functional development.
Tukey's Paper After 40 Years

The paper referred to is “The Future of Data Analysis,” published in 1962. Many authors have discussed it, notably Peter Huber, who in 1995 reviewed the period starting with Hotelling's 1940 article “The Teaching of Statistics. ” I extend the scope of Huber's remarks by considering also the period before 1940 and developments since 1995. I ask whether statistics is a science and suggest that to attract bright students to our subject, we need to show them the excitement and rewards of applied work.
Molecular Genetics of Spinocerebellar Ataxia Type 8 (SCA8)

Spinocerebellar Ataxias (SCAs) belong to a group of autosomal dominant, late-onset neurodegenerative disorders characterized by slowly progressive ataxia that eventually leads to severe gait, speech, coordination and sensory loss. The majority of these diseases result from expanded polyglutamine tracts in the encoded protein as seen in SCA1, SCA2, SCA3, SCA6, SCA7 and Dentatorubral-Pallidoluysian Atrophy (DRPLA). However, two novel forms of SCAs, SCA8 and SCA12, are associated with trinucleotide repeat expansions in non-translated regions of the genes. In the case of SCA8, the CUG expansion occurs at the 3’end of a processed non-coding RNA. While understanding of how expanded polyglutamine tracts compromise or alter protein function has advanced rapidly in the last five years, understanding of how trinucleotide repeat expansions alter the function of the non-coding SCA8 RNA and lead to human disease remains quite limited. Encouragingly, as discussed in this review, recent studies from murine and Drosophila models have provided new insights into both the cellular context in which SCA8 normally operates and the potential role of CTG expansion in the disease. Continued exploration of these genetically tractable model systems will further illuminate the biology underlying SCA8 disease, ultimately providing the necessary foundation on which to develop effective therapeutic interventions.

We present a 4-year-old boy in whom magnetic resonance imaging showed complete agenesis of the corpus callosum, which has not been presented in the literature. (J Child Neurol 2005;20:691—693).
A low power bandgap voltage reference for Low-Dropout Regulator

A low power Bandgap Voltage Reference (BGR) is designed to supply a voltage reference for a low voltage Low-Dropout Regulator (LDO). This bandgap design consists of a bandgap core circuit, an output stage and a start-up circuit. The output of the bandgap adopted sub-1V voltage reference through the output stage circuit. The bandgap is simulated using 0.13 μm CMOS process. This BGR circuit provides voltage reference of 64mV± 1mV over -25°C to 120°C temperature range. The power supply of this BGR circuit is 1.20 V and the total current is 20 μA, thus resulting a low total power consumption of 24μW. The total layout area for this bandgap design is 66μm × 100μm.
Head Mounted Device for Real World Text to Speech Conversion

There is no low-cost aid for visually impaired people despite several advances in technology. This paper presents a mobile head-mounted device to detect and convert text in natural scenes to speech. The major components of the device are a Raspberry Pi, a high definition webcam, earphones and a portable power bank. The Raspberry Pi is connected to the webcam which captures the image. A text detection algorithm using Class Specific Extremal Regions (CSERs) is implemented to detect the text in complex natural scenes. The segmented image is passed to the Tesseract OCR engine for text detection. The identified text is converted to audio using the espeak Python module in the Raspberry Pi. Thus, a visually impaired person can use this device to hear all the text in his surroundings like the name of a shop, public notices, billboards, road directions, etc.
The role of Helicobacter pylori infection in the development of allergic asthma

Asthma is one of the most prevalent chronic diseases in developed countries, with steady increases in asthma prevalence evident, particularly in the last few decades. As genetic factors are unlikely to contribute to the rise in asthma prevalence, changes in lifestyle and exposure to environmental stimuli have been proposed to account for this trend. The ‘disappearing microbiota’ hypothesis postulates that major shifts in the human microbiome, resulting from dramatic lifestyle changes, account for the increase in asthma prevalence. In this context, persistent gastric colonization with the human-specific pathogen Helicobacter pylori has been negatively associated with the occurrence of asthma in epidemiological studies. In addition, experimental models of allergic airway disease revealed a direct link between infection with H. pylori and suppression of allergic airway disease through the induction of regulatory T cells. These and other new insights hold the promise of opening up new avenues toward the development of innovative, new strategies directed at asthma treatment and prevention.
Identification of Chromosomal Shigella flexneri Genes Induced by the Eukaryotic Intracellular Environment

ABSTRACT Upon entry into the eukaryotic cytosol, the facultative intracellular bacterium Shigella flexneri is exposed to an environment that may necessitate the expression of particular genes for it to survive and grow intracellularly. To identify genes that are induced in response to the intracellular environment, we screened a library containing fragments of the S. flexneri chromosome fused to a promoterless green fluorescent protein gene (gfp). Bacteria containing promoter fusions that had a higher level of gfp expression when S. flexneri was intracellular (in Henle cells) than when S. flexneri was extracellular (in Luria-Bertani broth) were isolated by using fluorescence-activated cell sorting. Nine different genes with increased expression in Henle cells were identified. Several genes (uhpT, bioA, and lysA) were involved in metabolic processes. The uhpT gene, which encoded a sugar phosphate transporter, was the most frequently isolated gene and was induced by glucose-6-phosphate in vitro. Two of the intracellularly induced genes (pstS and phoA) encode proteins involved in phosphate acquisition and were induced by phosphate limitation in vitro. Additionally, three iron-regulated genes (sufA, sitA, and fhuA) were identified. The sufA promoter was derepressed in iron-limiting media and was also induced by oxidative stress. To determine whether intracellularly induced genes are required for survival or growth in the intracellular environment, we constructed mutations in the S. flexneri uhpT and pstS genes by allelic exchange. The uhpT mutant could not use glucose-6-phosphate as a sole carbon source in vitro but exhibited normal plaque formation on Henle cell monolayers. The pstS mutant had no apparent growth defect in low-phosphate media in vitro but formed smaller plaques on Henle cell monolayers than the parent strain. Both mutants were as effective as the parent strain in inducing apoptosis in a macrophage cell line.
Comparison and validation of SRTM and ASTER GDEM for a subtropical landscape in Southeastern China

This paper evaluates the quality characteristics of existing versions of 3-arc-second SRTM and 1-arc-second GDEM over Anji County, Zhejiang, China using reference elevations from a high-quality 1:10 k topographic map. Results show that SRTM has higher accuracy (RMSE =12.44 m) than GDEM (RMSE=14.20 m for Version 1, 12.76 m for Version 2); however, unsatisfactory void filling and an overall 1/2 pixel shift exits in SRTM version 4.1. Although spurious elevations over omitted water bodies still persist, GDEM Version 2 demonstrated significant improvement over Version 1. Accuracies of both SRTM and GDEM decrease on steeper slopes. Aspect also influences both the magnitude and the sign of errors. DEM accuracy in non-forested areas is considerably higher than that in forested areas. SRTM version 4.1 and GDEM version 2 possessed actual spatial resolutions of 90 m, despite both of them failed to match their nominal accuracies. SRTM Version 4.1 could be the first choice, while ASTER GDEM Version 2 would be a good alternative for areas where extensive voids exist in SRTM.
Isolation and characterization of a herpeslike (Hsiung-Kaplow) virus from guinea pigs.

Recently, Hsiung and Kaplow reported the isolation of a herpeslike agent from strain 2, but not from strain 13 or from "Hartley strain," guinea pigs [1]. Since strain 2 guinea pigs are highly susceptible to transmissible acute lymphoblastic leukemia (LoC) [2], it was inferred that there may be a causal relationship between the herpeslike agent and the leukemia. In June, 1967, we established colonies of strains 2 and 13 guinea pigs in our laboratory; the original animals were obtained from Dr. Maurice
Single-negative (SNG) metamaterials for mutual coupling reduction in high-profile antennas

In this paper, electromagnetic coupling between closely-spaced high-profile antennas is investigated with particular focus on multiple-input multiple-output (MIMO) systems. Monopole, and axial model helical antennas are considered in this study. Singlenegative (SNG) metamaterials insulator were designed and placed between the antenna elements. Numerical and Experimental results show that better impedance matching can be achieved when using the magnetic resonators, as compared to the air case. Moreover, an almost 20 dB reduction in mutual coupling between antenna elements has been achieved.
Risk Factors and Outcomes for Intestinal Carriage of AmpC-Hyperproducing Enterobacteriaceae in Intensive Care Unit Patients

ABSTRACT In a cohort of 1,209 intensive care unit (ICU) patients, the prevalence of intestinal colonization with high-level expressed AmpC cephalosporinase-producing Enterobacteriaceae (HLAC-PE) rose steadily from 2% at admission to 30% in patients with lengths of stay (LOS) exceeding 4 weeks. In multivariate analysis, LOS was the main predictor of carriage acquisition after adjustment on antimicrobial exposure. HLAC-PE infection occurred in 15% of carriers. Carriage and infection were associated with a marked increase in carbapenem consumption.
CPP-GMR Film With ZnO-Based Novel Spacer for Future High-Density Magnetic Recording

A new type of CPP-GMR film, which has ZnO-based novel spacer, was studied. A high MR ratio of 21.4% at RA of about 0.2 ¿¿m2 at room temperature was obtained by optimization of the fabrication condition of ZnO layer. Based on HRTEM observation, the ZnO spacer is crystalline which have c-axis orientation with wurtzite structure, and there are no metallic portions. The measured noise is in good agreement with Johnson noise fitted at T = 400(K). This result suggests that the contact at our ZnO-based spacer interface with magnetic electrode is ohmic. First principle calculations that used a simple model supported the existence of large spin dependent scattering at the interface of ZnO layer. These results indicate that higher signal to noise ratio can be achieved in this type of CPP GMR head even with lower MR ratio than MTJ head and it is very attractive candidate of future magnetic read sensor in HDDs.
Pertussis Immunization in the Global Pertussis Initiative North American Region: Recommended Strategies and Implementation Considerations

In North America, children currently receive 5 doses of a combined diphtheria-tetanus-acellular pertussis vaccine between the ages of 2 months and 6 years. Although this schedule has reduced the incidence of childhood pertussis, it has not led to the development of herd immunity in the total population, largely because pertussis immunity wanes with time. The time course over which immunity wanes is uncertain; however, high pertussis antibody titers in adolescents and adults indicate unrecognized infection in these groups. There is evidence that this group serves as a source of infection for young infants who are not fully immunized. Therefore, of the potential strategies reviewed by the North American Global Pertussis Initiative group, universal adolescent immunization would in theory reduce the risk of pertussis in this age group and may reduce transmission to young infants. However, because immunity probably wanes at the same rate in adolescents and children, the burden of disease will likely shift to older age groups, including young adults (parents of vulnerable infants). Therefore the ideal would be immunization of adolescents and adults, particularly those who are in contact with young infants. Adolescent immunization is already recommended in Austria, France, Germany and Canada, and participants in the Global Pertussis Initiative recommend that this strategy be implemented across North America with a view to eventually extending immunization to ínclude adults. The final decision to implement such a strategy will depend on pertussis surveillance studies and analysis of the effectiveness and tolerability of adolescent and adult pertussis immunization as well as program considerations related to feasiblity and economics.
Evaluation of a switched reluctance motor with magnetic slot wedges

The switched reluctance motor is a good candidate for electrical traction and more specifically in automotive applications. The conventional switched reluctance motor presents two major drawbacks which are torque ripple and stator vibrations. In this work, a solution to limit these problems is proposed: a switched reluctance motor with magnetic slot wedges is used to reduce the impact of vibrations through the analysis of the radial forces applied on the stator teeth, and their harmonic content. Indeed, these forces cause an undesirable vibro-acoustic behavior. In addition, it is shown that the proposed design allows the reduction of torque ripple which are the cause of power-train vibrations.
Identifying patients with suspected colorectal cancer in primary care: derivation and validation of an algorithm.

BACKGROUND Earlier diagnosis of colorectal cancer could help improve survival so better tools are needed to help this. AIM To derive and validate an algorithm to quantify the absolute risk of colorectal cancer in patients in primary care with and without symptoms. DESIGN AND SETTING Cohort study using data from 375 UK QResearch® general practices for development and 189 for validation. METHOD Included patients were aged 30-84 years, free at baseline from a diagnosis of colorectal cancer and without rectal bleeding, abdominal pain, appetite loss, or weight loss in the previous 12 months. The primary outcome was incident diagnosis of colorectal cancer recorded in the next 2 years. Risk factors examined were age, body mass index, smoking status, alcohol status, deprivation, diabetes, inflammatory bowel disease, family history of gastrointestinal cancer, gastrointestinal polyp, history of another cancer, rectal bleeding, abdominal pain, abdominal distension, appetite loss, weight loss, diarrhoea, constipation, change of bowel habit, tiredness, and anaemia. Cox proportional hazards models were used to develop separate risk equations in males and females. Measures of calibration and discrimination assessed performance in the validation cohort. RESULTS There were 4798 incident cases of colorectal cancer from 4.1 million person-years in the derivation cohort. Independent predictors in males and females included family history of gastrointestinal cancer, anaemia, rectal bleeding, abdominal pain, appetite loss, and weight loss. Alcohol consumption and recent change in bowel habit were also predictors in males. On validation, the algorithms explained 65% of the variation in females and 67% in males. The receiver operating curve statistics were 0.89 (females) and 0.91 (males). The D statistic was 2.8 (females) and 2.9 (males). The 10% of patients with the highest predicted risks contained 71% of all colorectal cancers diagnosed over the next 2 years. CONCLUSION The algorithm has good discrimination and calibration and could potentially be used to help identify those at highest risk of current colorectal cancer, to facilitate early referral and investigation.

Imaging for Concealed Weapon Detection

In today’s world, security forms an integral part in every aspect of life. The detection of weapons concealed underneath a person’s clothing is very much important to the improvement of the security of the general public as well as the safety of public assets like airports, building and railway stations, etc. Manual screening procedures for detecting concealed weapons are common in controlled access settings like airports, entrance to sensitive buildings and public events. It is desirable sometimes to be able to detect concealed weapons from a standoff distance, especially when it is impossible to arrange the flow of people through a controlled procedure. In this project we propose an automated weapon detection using millimeter wave imagining method. The millimeter wave scans the entire body, without causing any side-effects, for concealed weapon. We enhance the millimeter wave image and follow it up with segmentation. The system has built-in intelligence to detect the concealed weapon after segmentation. We also use wavelet based fusing techniques to pin-point the position of the concealed weapon General Terms Image Denoising, Algorithms et.
