Compact Switched-Beam Array Antenna with a Butler Matrix and a Folded Ground Structure

A compact switched-beam array antenna, based on a switched Butler matrix with four folded ground antennas, is presented for unmanned aerial vehicle (UAV) applications. The folded ground structure, including a slotted patch radiator surrounded by multiple air-gapped ground layers, is adopted to maximize compactness. The extra ground layers provide extra capacitive coupling around the patch antenna, resulting in a down-shift of resonant frequency and a reduction in the antenna size. Also, to optimize aerial operation with a wider beam coverage, the 1 × 4 array is integrated with a switched Butler matrix controlled by a microcontroller unit (MCU). The choice of the Butler matrix reduces the complexity of beamforming circuitry and avoids the use of high-cost phase shifters requiring extra control-bit signals. Further, the array antenna is optimized for high isolation among the antenna ports and a minimal UAV body effect. Then, the proposed structure was verified at 1.96 GHz for test purposes only, and the array size, excluding the antenna case, was 2. 16λo × 0. 54λo × 0. 07λo. The measured 10 dB impedance bandwidth for all antenna elements in the array was always better than 3.4%, and the isolation among the antenna ports was also better than 19 dB. The measured peak gain, excluding the loss of the switched Butler module, was about 9.98 dBi, on average. Lastly, the measured peak scan angles were observed at −39°, −17°, 9° and 31° according to switching modes.

The evaluation of the high peak of speed in footballers: Survey of all category from an amateur youth academy

The analysis of youth football performance can help and increase the selection of talents and help coaches to work better during training, this can be possible with a multifactorial analysis of footballers using even specific hardware such as GPS, video-tracking and accelerometer. The aim of this study was to investigate the high peak speed (H.P.S) in youth football category and to determinate, how much times, footballers reach it during matches. Were analysed 120 athletes belonging to an amateur academy, 30 for each category U-12, U-14, U-16 and U-18. Was performed a sprint test on 30 meters in order to assess the average HPS, for each category from the academy, and in the end analyse how much the H.P.S is reached during one test match performed for every category. The sprint tests on 30 meters were performed using GPS 10Hz (K-Sport Universal, Montelabbate, Italy), each athlete repeats the test 3 times the best performance was selected. The calculation of the average events for players during matches (AE-P) was calculated dividing the HPS events by the numbers of players (9 for U-12, 11 for U-14, U-16 and U-18). Results shows of events upper the H.P.S are growing exponentially by U-16 to U-18, with a difference of 72%. The AE-P shows in average how much events are expected by players; no particular difference was showed from U-12 to U-16 (with a value starting from 0,5 and a maximum of 0,6 events). In the U-18 the events exponentially grow and reach the value of 1,3. All the results let to assume that the maturation ratio in the academy, influence the variations and differences in the results. The analysing of the PPM even for young footballers can be the way to rationalize performance evaluation, as regards the study of H.P.S between category, it can provide useful information to evaluate, predict and help the talents research.
The Indo-Pacific Sergeant Abudefduf vaigiensis (Quoy & Gaimard, 1825) (Perciformes: Pomacentridae) in Libya, South-Central Mediterranean Sea

The Indo-Pacific Sergeant Abudefduf vaigiensis (Quoy & Gaimard, 1825) (Chordata: Pisces: Actinopterygii: Perciformes: Pomacentridae) is first recorded in the south-central Mediterranean Sea (Libya), based on the external morphology and the barcoding of a fragment of the cytochrome c oxidase subunit I gene. Present sightings from field surveys and social media include juveniles, sub-adults, and a single adult specimen, suggesting that the species is now established in Libyan waters. No certainties occur regarding timing and possible pathway of arrival of this species in the area, and it may have simply gone undetected for years. The joint effort of field studies and citizen science projects in collaboration with international organizations continues shedding light on bioinvasions in Libya, with valuable outcomes for the Mediterranean marine biology as a whole.
Model reduction for nonlinear aeroelasticity using the Discrete Empirical Interpolation Method

A novel surrogate model is proposed in lieu of computational fluid dynamic (CFD) code for fast nonlinear aerodynamic modeling. First, a nonlinear function is identified on selected interpolation points defined by discrete empirical interpolation method (DEIM). The flow field is then reconstructed by a least square approximation of flow modes extracted by proper orthogonal decomposition (POD). The proposed model is applied in the prediction of limit cycle oscillation for a plunge/pitch airfoil and a delta wing with linear structural model, results are validate against a time accurate CFD-FEM code. The results show the model is able to replicate the aerodynamic forces and flow fields with sufficient accuracy while requiring a fraction of CFD cost.

Breastfeeding Encouragement and Support of Health Professionals in the Hospitals

The purpose of this study was to investigate encouragement experience on breastfeeding of health professionals, and the support in their hospitals on breastfeeding.A questionnaire on breastfeeding was administered to the obstetricians. pediatricians and nurses at the department of pediatrics or obstetrics of university hospital and private hospital in Seoul and Choong-Chung Province in South Korea. Total numbers of study subjects were 346 (pediatrician 67, obstetrician 41, nurse 238). Data was statistically analyzed according to descriptive statistics. Chi-square test and multivariant analysis.The results were as follows: 1. Most of the respondents (93. 6%) had a knowledge regarding breastfeeding which had more advantage than formula-feeding. But their experience to educate the mother about breastfeeding was very limited(34.8%). The major problems were insufficient concern of healthcare professionals. no trained personnels and lack of education programs on breastfeeding.2. Most of the respondents(82%) had learned breastfeeding management in class at the university. But 2/3 of them had not been educated on breastfeeding management after graduation.3. More than half of the hospitals had no breastfeeding education programs. And they recommended the formula-feeding to the mothers.4. Seventy percent of the respondents recognized that breastfeeding information offered to the mothers in their hospitals might help to increase the rate of breastfeeding. But only 40% of hospital had offered breastfeeding information using pamphlets or brochures.In our study, a majority of respondents had not been educated on breastfeeding after graduation. A personal experience in breastfeeding is known predictor of confidence in breastfeeding. Educational programs may have an effect to change the health professionals behavior. Therefore, it is necessary to assist health professionals in obtaining more knowledge about breastfeeding. Continuing education programs to health professionals should be offered by nation and regional organization.
Study on the antimicrobial activity and synergistic / antagonistic effect of interactions between antibiotics and some spice essential oils against pathogenic and food-spoiler microorganisms 1

Spices and herbs containing essential oils (EOs) in the range of 0.05–0.1% have demonstrated antimicrobial activity against pathogenic and spoilage micro-organisms. The aim of the present study is (1) to investigate invitro antimicrobial effects of five spices and herbs, namely, Piper nigrum (Black pepper), Coriandrum sativum (coriander), Cuminum cyminum (cumin), Mentha piperita (Peppermint) and Rosmarinus officinalis (Rosemary) against different bacteria and fungi species, and (2) to discuss the in-vitro possible effects between the essential oils and antibiotics. The microorganisms used in this study were Micrococcus luteus, Bacillus cereus, Salmonella typhimurium, Listeria monocytogens, Escherichia coli, Lactobacillus acidophilus, Staphylococcus aureus, Streptococcus pneumoniae, bacteria and Candida albicans fungi. The results indicated that essential oils of Rosmarinus officinalis, Coriandrum sativum, Piper nigrum, Cumium cyminum and Mentha piperita showed antimicrobial activity in the range of 6-50 mm 2μlinhibition zone to the microorganisms tested, using disc diffusion method. Standard antibiotics such as Gentamicin (10 μg), Amoxicillin/clavulanic acid (20/10) (30 μg), Erythromycin (15 μg), Norfloxacin (10 μg) discs were used for comparison with the antimicrobial activities of essential oils of these plants. In addition, antibacterial activity of essential oils of these plants was investigated effects when used together with these standard antibiotics in vitro. However, antibacterial activity changed also by in vitro interactions between these standard antibiotics and essential oils of these plants. Synergic, additive or antagonist effects were observed in antibacterial activity.
Lateral Column of the Foot Arthroplasty With Interpositional Fascia Lata Graft: A New Technique

Tarsometatarsal reconstruction is common after a traumatic event as joint pain develops and progresses to chronic arthritis. Often, the surgeon elects to reconstruct the foot, performing arthrodesis of the medial, middle, and lateral columns. However, debate exists regarding whether lateral column reconstruction should consist of arthrodesis or arthroplasty at this joint level. This is attributed to the greater amount of motion present to the lateral versus the medial and middle columns. Although many sources advocate joint salvage through arthroplasty, few techniques are described in the literature as to how to accomplish this. We present a review of the literature pertaining to lateral column arthroplasty as well as a technique performed by the authors utilizing a tensor fascia lata allograft as an interpositional spacer after joint resection. The senior author has used this technique with great success for many years. Level of Evidence: Diagnostic Level 4. See Instructions for Authors for a complete description of levels of evidence.
Breeding and quality of soft-textured durum wheat

Kernel hardness in common wheat exerts a strong impact on yield and granularity of flour, starch damage and water absorption, rheological and baking properties. Durum wheat cultivars are characterized by an extra-hard kernel. This extremely hard texture is mainly due to the absence of puroindolines A and B, two basic, tryptophanand cysteinerich polypeptides encoded by two closely linked genes named Pina-D1 and Pinb-D1, located in the short arm of chromosome 5D. In order to insert puroindoline genes, durum wheat line «Cappelli M» lacking the Ph1 locus was used as the female parent in a cross with the 5D(5B) substitution line of durum wheat cv Langdon carrying puroindolines wild-type alleles. F9 lines, three Soft Durum Lines (SDL) homozygous for wild-type alleles Pina-D1a and PinbD1a, and three Hard Durum Lines (HDL), lacking the Pina-D1 and Pinb-D1 genes, were selected. Microsatellites located on 5D chromosome suggested that SDLs contain only a small 5DS fragment, inferior to 14.4 cM in size. Accumulation of puroindolines reduced SDLs hardness indexes to those typical of soft-textured common wheat cultivars. Flour extraction rate of SDLs was approximately 60% higher than that of HDLs and grain softness strongly decreased farinograph and alveograph parameters. On the contrary, reduction in kernel hardness did not significantly affect global quality score of spaghetti, whereas SDL showed a small, but significant, increase of the bread loaf volume. These results suggest that modulation of kernel hardness in durum wheat does not impair its pasta-making potential and may improve its baking performance. Availability on the wheat scenario of soft-textured durum wheat genotypes may have important practical and useful implications for breeding multiple-purpose durum wheat (pasta, bread, biscuits). Crosses are on going to improve the yellow index which are consistently lower in the finer flour and semolina of soft-textured durum wheat.
The Influence of Laser Sintering Modes on the Conductivity and Microstructure of Silver Nanoparticle Arrays Formed by Dry Aerosol Printing

The demand for the development of local laser sintering of nanoparticle arrays is explained by the expanding needs for printed electronics for functional microstructure formation, on heat-sensitive substrates in particular. This work is based on the research into the sintering of arrays of silver nanoparticles synthesized in a spark discharge and deposited on a substrate by focused aerosol flow. The sintering was done by continuous and pulsed lasers with wavelengths 527, 980 and 1054 nm. Sintered samples were studied by measuring the resistivity, cross-section profile area and microstructure features. The highest average conductivity, equal to the half of the bulk silver conductivity, was achieved when sintering by continuous radiation with a wavelength 980 nm. The results showed that when using pulsed radiation the direct heating of nanoparticles in the sample surface layer dominates with the formation of a pore-free conductive layer of around 0.5 μm thick and crystallite of 70–80 nm size. It was found that laser sintering by radiation with a wavelength 527 nm required an order of magnitude lower specific energy costs as compared to the longwave laser radiation. The high energy efficiency of laser sintering is explained by special conditions for radiation absorption at plasmon resonance.

Assessment of Genetic Variations Associated With Susceptibility to Psoriasis Among Iraqi Population

ackground: Psoriasis is an immune –mediated, chronic hyperproliferative disease of the skin. Genetic association studies have identified multiple psoriasis risk loci; however, the frequency of variations at these loci differs quite strikingly among the populations, suggesting heterogeneity in the genetic susceptibility to psoriasis. Aim of the study: to assess the possible association of selected genetic variants with psoriasis among Iraqis. Methodology: In this case-control study, 50 psoriasis patients and 40 control subjects were enrolled. Peripheral blood was obtained from all patients and control subject and used for extraction of genomic DNA. Amplification Refractory Mutation System (ARMSPCR) was used to detect 3 SNPs in IL-20RA(Rs1184860, Rs1167846 and Rs1167849), whereas convention PCR was used to assess deletions in late cornified envelope 3B and late certified envelope 3C (LCE3B and LCE3C) genes. Results and Discussion: Nine haplotypes were identified by SNPs atIL-20RA gene; the haplotype TTA (Rs1184860, Rs1167846 and Rs1167849, respectively) was associated with psoriasis 19(38%), whereas the CTA haplotype had a protective effect 12(30%). The frequencies of LCE3B deletion in both patients and control groups were 14(28%) and 20(50%) respectively, while the frequencies of LCE3C deletion were 16(32%) and 20(50%) among patients and control respectively. Statistical analysis revealed a significant association between LCE3B deletion and susceptibility to the psoriasis (P < 0.05). The frequencies of homozygous deletion (LCE3B_LCE3C del) in both patients and control groups were 13(26%) and 9(22.5%) respectively. The statistical analysis had revealed a non significant (P > 0.05) association between LCE3C deletion and homozygous deletion (LCE3B_LCE3C del) with susceptibility to psoriasis. Conclusion:The haplotype TTA of IL-20RA gene has a role in the susceptibility to the psoriasis among Iraqi population.In addition, no association was found between LCE3B_LCE3C deletion and psoriasis in Iraqi population. Keywords; psoriasis, IL-20RA, LCE3C, LCE3B, SNPs,deletion
Efficient and cost-effective dye-sensitized solar cells using MWCNT-TiO2 nanocomposite as photoanode and MWCNT as Pt-free counter electrode

In the present study, a new cost-effective and efficient configuration [n-MWCNT-TiO2/N3/MWCNT] of dyesensitized solar cell (DSSC) is proposed and fabricated, where n-MWCNT-TiO2 is the nano composite of multiwall carbon nanotube (MWCNT), and titanium dioxide (TiO2) in different mass proportions, sensitized by N3 dye used as a photo anode, and MWCNT is the material for the counter electrode. In the [n-MWCNT-TiO2/N3/ MWCNT] configuration, the photo anode with four mass proportions (n=0.03%, 0.06%, 0.09% and 0.12%) were used as a design variant, and it was found that the photovoltaic efficiency as high as 7.15% was achieved when the nano composite of 0.06%-MWCNT-TiO2 was applied as a photoanode in the proposed DSSC configuration. Besides achieving a 13% photovoltaic efficiency enhancement compared to the ubiquitous [TiO2/N3/ Pt] DSSC configuration, the replacement of Pt with inexpensive MWCNT in the [n-MWCNT-TiO2/N3/MWCNT] DSSC ensures the cost effectiveness of the proposed configuration. The morphological and optical characterization of the n-MWCNT-TiO2 photoanode (nanocomposite) films, the stability and catalytic activity of MWCNT counter electrode, UV–VIS absorption spectroscopy, current-voltage characteristics, incident photon to electron conversion efficiency and the electrochemical impedance spectroscopy of the fabricated DSSCs were performed in order to elucidate the improved performance of the [n-MWCNT-TiO2/N3/MWCNT] configuration. Based on these characterization studies, it was found that the observed enhancement of light absorbance in the visible spectral region, the improved electron transportation, decreased recombination of electrons with oxidized dye and redox mediator, better catalytic activity of MWCNT counter electrode are the key contributory factors for the increased photovoltaic efficiency of the [n-MWCNT-TiO2/N3/MWCNT] DSSC configuration.
