Shielding Effectiveness Estimation of a Metallic Enclosure with an Off-center Aperture for Obliquely Incident and Arbitrary Polarized Plane Wave

─ A circuit model for the shielding effectiveness (SE) estimation of a metallic enclosure is proposed, whose off-center aperture is irradiated by the obliquely incident and arbitrary polarized plane wave. This new model has advantages in the following aspects. First, it can deal with the arbitrary angular and polarized incident wave other than the normal incident wave. The incident wave angle and polarization direction are considered in the proposed analytical formulas. Second, higher-order modes such as TEmn and TMmn are included to enable the model to be applicable in higher frequencies. Third, the impedance of the enclosure wall is considered rather than the perfect conductor assumption used in the published literatures, which removes the deficiency that the aperture impedance is zero when the length of the aperture is equal to an integral number of the wavelengths. The influences on the SE from different parameters such as the incident wave angle, the polarization direction as well as the enclosure wall thickness are investigated. Finally, the accuracy of the proposed model is validated by measurements, simulations and comparisons with other literatures. The proposed method is particularly useful for the shielding enclosure design in the electronic manufacturing industry. Index Terms ─ Circuit model, higher-order modes, obliquely incident, rectangular enclosure, shielding effectiveness.
Optimizing of Synthetic Seed of Malling apple (Malusdomestica) Rootstocks cv. M26 and cv. MM106

Malling Increasing demands for apple across the world requires its rapid production. Agricultural biotechnology has met this need and has prevented some problems during adolescence period and long generation. We investigated embryonic and non-embryonic callus through cultivating apical and lateral buds on different treatments with MS base culture and BAP (0-2.5 mg/l) and IBA (0-5 mg/l) hormones Kin and NAA hormones. The highest percent of embryogenesis related to T11 treatment (IBA 4 mg/l, BAP 1 mg/l) and T23 (IBA 4 mg/l, BAP 2.5 mg/l). The embryos were in corpuscular stage. Then third sub-culture was performed and all calluses and embryos were delivered to their corresponding treatments. K5 (NAA 1 mg/l, Kin 0.5 mg/l) and K8 (NAA 3 mg/l, Kin 1 mg/l) yielded the highest amount of callus (5.3 mm). The embryos remained in corpuscular stage and they did not show reproductive ability and developmental process. After preparation of artificial seed no regeneration was seen. By embryogenesis of MM.106 and M.26, the purpose of this research is improving a protocol for generation of two somatic cultivars.
Evaluation of antioxidant activity of Murraya koenigii (L.) Spreng using different in vitro methods

The present study investigates the phytochemical composition and antioxidant potential of three different extracts of Murraya koenigii. Murraya koenigii (Linn.) Spreng, locally known as “curry veppila” (curry leaf tree) belonging to the Rutaceae family, is commonly used as raw material for traditional medicinal formulation in India. Evaluating the phytochemical composition and antioxidant potential becomes essential if it is to be consumed as a drug. Three different extracts (Methanol, Hydro alcohol and Aqueous) of Murraya koenigii leaves were screened for their phytochemical composition and antioxidant activity using standard protocols. The results of phytochemical analysis reveals the presence of tannins, saponins, flavonoids, phenolic compounds, alkaloids, cardiac glycosides, phytosterols and triterpenoids in various extracts. The total phenolics and flavonoids were rich in hydroalcoholic extracts. Hydroalcoholic extract shows strong antioxidant activity. Result of the present study shows that hydroalcoholic extract of Murraya koenigii was rich in phenolics and flavonoids and have strong antioxidant potential. The strong antioxidant potential of the plant may be due to its high phenolics and flavonoids content.
Dwingeloo surveys and the Galactic magnetic field

Aims. We investigate the structure of the Galactic magnetic field in the 2nd Galactic quadrant using radio continuum polarization data from the 325 MHz WENSS (WEsterbork Northern Sky Survey) survey in combination with earlier single-dish observations. Methods. We study gradients in polarization angle along Galactic longitude and latitude in the region 130◦ <∼ l <∼ 173◦ and −5◦ <∼ b <∼ 31◦. These gradients were determined with a new method that we developed to efficiently and reliably fit linear gradients to periodic data like polarization angles. Since the WENSS data were obtained with a synthesis array they suffer from the “missing short spacing” problem. We have tried to repair this by adding an estimate of the large-scale emission based on the single-dish (Dwingeloo) data obtained by Brouw and Spoelstra. Combining all available data we derive a rotation measure map of the area, from which we estimate all 3 components of the magnetic field vector. Results. In the part of WENSS where large-scale structure in polarized intensity is relatively unimportant, we find that the magnetic field is predominantly perpendicular to the line-of-sight, and parallel to the Galactic plane. The magnetic field components along the line-of-sight and along Galactic latitude have comparable values, and the strength of these components is much smaller than the strength of the total magnetic field. Our observations also cover part of the so-called “fan” region, an area of strong polarized intensity, where large-scale structure is missing from our WENSS data. We tentatively show that Faraday rotation occurring in front of the Perseus arm is causing both the WENSS RM and the RM towards the fan region observed in previous single-dish surveys, and we suggest that the fan is formed by local emission that originates in front of the emission we see in WENSS.

Boy-Child Participation and Retention in Public Secondary Schools: The Role of Socio-Economic Factors with Examples from Baringo County, Kenya

This paper is premised on the findings of a study that sought to investigate factors that influence the participation and retention of the boy-child in public secondary schools in Baringo County, Kenya. Specifically, the study aimed at evaluating the effects of socio-economic factors on boy-child participation and retention in public secondary schools in Baringo County. Principles of the education production function theory guided the study. The study adopted a pragmatic world view (mixed method approach) with a sample size of 573 comprising form three boys’ students, teachers and Quality Assurance and Standards Officers from Baringo County. The researcher adopted stratification, simple random sampling and purposive strategies for setting up samples. Questionnaires, interview schedules and document analysis were used for data collection and data analyzed using SPSS (ver 20). The study established that there are socio-economic and school-related factors affecting participation and retention of boys. In particular, poverty, family size and number of siblings per household, child labour and desire for earnings, and educational attainment of parents determine boy participation and retention in public secondary schools in Baringo County. The paper concludes that financial constraints hinder the participation and retention of boys in public secondary schools in Baringo County due to the fact that the meagre resources that are available are channelled to catering for basic survival. The paper recommends that measures should be put in place to ensure that needy students receive financial aid towards achieving their educational goals.
The mnemic neglect model: Experimental demonstrations of inhibitory repression in normal adults

Normal adults recall poorly social feedback that refers to them, is negative, and pertains to core self-aspects. This phenomenon, dubbed the mnemic neglect effect, is equivalent to inhibitory repression. It is instigated under conditions of high self-threat, it implicates not-thinking during encoding, and it involves memories that are recoverable with such techniques as recognition accuracy.
Trace Elements in Common Potatoes, Sweet Potatoes, Cassava,Yam and Taro

The paper reports on the results of a survey of trace elements in common potatoes, sweet potatoes, cassava, yam and taro. The levels of aluminum, chromium, manganese, nickel, cobalt, molybdenum and cadmium in common potatoes, sweet potatoes, cassava, yam and taro consumed in Mato Grosso do Sul state, Brazil were evaluated. The concentrations were measured using a Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES, iCap 6000 ® Thermo Scientific, USA). It was shown that the levels of biometals in tubers, with the exception of aluminum and chromium, vary in a broad range, but do not exceed the limits established by the Brazilian and International legislation when available. No major concerns were identified for the health of consumers. The concentrations of aluminum in all tubers (1.53 2.9 mg/kg) and chromium in taro (0.41 mg/kg) are higher, possibly reflecting the local soil characteristics or contamination and needing geochemical information.
Bacterial Flora from Healthy Clarias Gariepinus and their Antimicrobial Resistance Pattern

The antibiotic resistance of bacteria isolated from Clarias gariepinus from 3 farms in Ago-Iwoye, Nigeria was investigated. Morphological and biochemical characteristics of isolates revealed that majority of the bacteria belonged to the family Enterobacteriaceae. Staphylococcus aureus and Pseudomonas aeruginosa were also recovered. E. coli strains were highly resistant to ampicillin, chloramphenicol and oxytetracycline (82.4%). Majority of the Pseudomonas aeruginosa were resistant to ampicillin (63.6%), amoxycillin (54.5%), nalidixic acid (63.6%) and oxytetracycline (72.7%), whereas most of the Salmonella spp. were resistant to erythromycin (85.7%), gentamycin (71.4%), amoxicillin (57.1%), chloramphenicol (57.1%) and sulphamethoxazole (57.1%). All isolates were highly sensitive to ciprofloxacin, novobiocin and ofloxacin. While the presence of potentially pathogenic bacterial species as observed in the study may not present a serious human health hazard because of heat treatment accorded fish before consumption, the presence of antibiotic resistant strains should not be ignored because of the potential for horizontal gene transfer in the food chain.
Labour Commitment and Firm's Productivity in Nigeria: A Case Study of Global Soap and Detergent Industries Limited, Ilorin, Kwara State.

This study attempts to find the relationship that exists between labour commitment and firm's productivity. It also examines the impact of employees' sex, marital status and occupational status on commitment to work. One hundred workers were drawn as sample from Global Soap and Detergent Industries Limited, Ilorin, to aid the research. An instrument title "Labour commitment and productivity Questionnaire" (LCPQ) was used for collecting data which was analyzed with statistical tables, simple percentage and chi- square statistics. The findings showed a high positive relationship between labour commitment and productivity. Also, the study revealed a significant difference in the commitment to work of married and single employees, male and female employees as junior and senior company employees. Therefore, the management should shelve away the idea of leadership styles who believes that productivity and profit are the goals of an enterprise without considering the plight of the workers. Rather they should try as much as possible to make sure that workers are credited for a job well done. Apart from giving workers more pay, their promotion must also be regular. Lastly, the agreement ever reached with the union should be met.
An Optimal Linearization Method of Parameter Design for NTC Thermister Interface Circuit

The thermister based temperature measurement scheme is widely applied for its low cost, strong stability and well flexibility. As the property between resistance and temperature is nonlinear, the practical application of thermister usually relies on the method of table look-up. Inevitably, that leads to the problems of poor versatility and large memory cost. Based on the analyses of resistance and temperature property, we propose an optimal linearization method of parameter design for NTC thermister interface circuit in this paper. The proposed approach is simple, but has a good linearity and high sensitivity. Test results are given to support the theoretical analyses and conclusions.
Comparative Genomics of Pseudomonas aeruginosa PAO1 and Pseudomonas putida KT2440: Orthologs, Codon Usage, Repetitive Extragenic Palindromic Elements, and Oligonucleotide Motif Signatures

Pseudomonas aeruginosa PAO1 and Pseudomonas putida KT2440 were compared for global genome features. About half of the coding sequences share more than 50% amino acid sequence identity. The alignment of orthologs shows an X-type pattern, with large sections of conserved gene order indicative of symmetric inversions around the origin and terminus of replication since the two taxa diverged from a common ancestor. However, codon usage patterns are different in the two type I pseudomonads, as indicated by unrelated genome codon index and codon adaptation index pro les. The P. aeruginosa and P. putida chromosomes share similar fractions of global repeats and contain several hundred repetitive extragenic palindromic (REP) elements, part of which are organized in regularly spaced clusters as bacterial interspersed mosaic elements. The frequency and map position of all 2-meric to 14-meric oligonucleotides were determined in the two genomes. Among the short oligonucleotides the universally rare TA, CTA, TAG, and CTAG and stretches of oligoG and oligoC are strongly counterselected in the GC-rich pseudomonads. Frequent words encode peptides with strong codon bias, such as the tripeptide LLL.
Isolation and Characterization of a Cytochrome P450 Gene from Muscari armeniacum

Flavonoid 3’5’-hydroxylase (F3’5’H), a member of the cytochrome P450 family, is the key enzyme for the expression of blue or purple flower color. By a polymerase chain reaction (PCR)-based strategy using a degenerate primer designed from the conservative region of the F3’5’H genes, a full-length cDNA (accession number AB127340) was cloned from blue flower tepals of Muscari armeniacum ‘Blue Pearl’, and its genomic clone designated MaP450 (accession number AB127341), was isolated from leaves. Nucleotide sequence analysis revealed that MaP450 contains an open reading frame (ORF) of 1512 bp, which consists of two exons (888 and 624 bp) encoding a polypeptide of 503 amino acid residues. The deduced amino acid sequence of MaP450 has several conserved regions of the cytochrome P450 proteins, but shows only 34-37% identities with those of previously reported F3’5’H genes. Southern blot analysis showed that there are 5-6 copies of MaP450 in the genome of M. armeniacum ‘Blue Pearl’. High-performance liquid chromatography (HPLC) and reverse transcription-polymerase chain reaction (RT-PCR) analyses revealed that MaP450 is expressed developmentally paralleling anthocyanidin accumulation in the tepal. The expression pattern of MaP450 is similar to those of the majority of genes involved in the flavonoid biosynthetic pathway. Transcripts of MaP450 were markedly detected in tepals of Muscari genotypes with colored flowers, but only slightly detected in those of genotypes with white flowers. These results indicate that MaP450 may be a P450 gene involved in the flavonoid biosynthetic pathway in Muscari species.
Effects of Multiple Doppler Radar data assimilation on the numerical simulation of a Flash Flood Event during the HyMeX campaign

An analysis to evaluate the impact of assimilating multiple radar data with a three dimensional variational (3D-Var) system on a heavy precipitation event is presented. The main goal is to establish a general methodology to quantitatively assess the performance of flash-flood numerical weather prediction at mesoscale. In this respect, during the first Special Observation Period (SOP1) of HyMeX (Hydrological cycle in the Mediterranean Experiment) campaign several Intensive Observing Periods (IOPs) were launched and nine occurred in Italy. Among them IOP4 is chosen for this study because of its low predictability. This event hit central Italy on 14 September 2012 producing heavy precipitation and causing several damages. Data taken from three C-band radars running operationally during the event are assimilated to improve high resolution initial conditions. In order to evaluate the impact of the assimilation procedure at different horizontal resolution and to assess the impact of assimilating multiple radars data, several experiments using Weather Research and Forecasting (WRF) model are performed. Finally, the statistical indexes as accuracy, equitable threat score, false alarm ratio and frequency bias are used to objectively compare the experiments, using rain gauges data as benchmark.
Reversible Capture of CO 2 by Cucurbit [ 7 ] uril Absorbent

Traditional amine absorbents for CO2 are oftentimes corrosive to equipment and degrade through oxidation, thus severely restricting the wide application in CO2 capture. Herein, a supramolecular approach to CO2 capture by cucurbit[7]uril (CB[7]) complex was developed. NH2(CH2)6NH2CB[7] complex can convert CO2 to bicarbonate product. Furthermore, the CB[7] complex can be reused to absorb CO2 over 5 times in solid state, thereby providing a green absorbent to CO2 with regard to high stability, non-corrosiveness and convenient transportation.

Utilization of hydrogen gas production for electricity generation in fuel cell by Enterobacter aerogenes ADH 43 with many kinds of carbon sources in batch stirred tank reactor

Enterobacter aerogenes ADH-43 is a hydrogen gas (H 2 ) producing mutant bacterium and a facultative anaerobic microbe. This double mutant was obtained by classical mutagenetically treated in order to enhance H 2 production. In addition, this mutant has ability to degrade molasses from sugar factory as well as other carbon sources. The main goals of this research were to use E. aerogenes ADH-43 for fermentation in order to decide the best carbon sources and optimum concentration from molasses, glucose, cassava sugar, glycerol and biodiesel waste media in vial bottle. Moreover, to stabilize H 2 production, it was operated at 37°C and an initial pH 6.8. Performing the research in batch and fed-batch culture, utilizing it by converting to electricity using fuel cells in 50 ml vial bottle, 2% total sugar concentration of sugar cane molases was found to be the highest H 2 production (9.38 L H 2 /L medium) during 24 h fermentation. It was also observed that in batch culture at 12 h fermentation, the volume, flow rate maximum, and the yield of H 2 production were 1.6 L H 2 /L sugar molases, 73.4 ml H 2 /min, and 2.99 mol H 2 /mol sugar molases, respectively. Both sugar was consumed perfectly, colony count was 1.7 10 7 cfu/ml, pH was nearly constant at 6.0, and finally the H 2 was drifted to fuel cell to generate electrical power until 4 V 0.25 A. Moreover, the volume, flow rate maximum, and the yield of H 2 production were 2.12 L H 2 /L sugar molases, 107.7 ml H 2 /min, and 3.84 mol H 2 /mol sugar molases, respectively when the fed-batch culture was performed. This means nearly 1.3- fold yield of H 2 as compared to batch culture was obtained by adding 0.5 L of 2% sugar cane molasses at 5 and 12 h of fermentation in order to reach 7.0 V, 5.3 W and 0.38 A by a fuel cell. Keywords: Enterobacter aerogenes ADH-43, H 2 production, molasses and fuel cell
