Mode NASA blade used to calculate the power generator for (VAWT) by drag and lift coefficients

One of the confrontations with increasing demand on power in the entire world the methodologies of provided power divided into traditional methods against renewable methods. This article presents a simulation model to estimate the integrated power from vertical access wind turbine (VAWT) stages of development of a simulation model of local power supply system (LPSS) with (VAWT). However, wind power is one of the quickest developing advances for the sustainable power age. Disturbingly, in the ongoing years a few instances of corruption on telecommunication systems frameworks have emerged because of the presence of wind ranches, and costly and in fact complex restorative estimations needed. The grade of variation of power verified according to the grid size. The parameters were taken in the study through the preparation of the model are (efficiency, cost, and system response) compared to the benefits against disadvantages when combining the two systems to achieve a high performance of the power stability

UPOTREBA POLIETILENSKOG GLIKOLA (6000) ZA DEAKTIVIRANJE TANINA U LIŠĆU DRVEĆA ZA BRŠĆENJE U ISTOČNOJ LIBIJI

This study was conducted to investigate the effect of different levels of Polyethylene glycol (PEG) on in vitro gas production of some tree leaves grown in Eastern Libya. The samples used were Ceratonia siliqua, Pistacia lentiscus, and Acacia cyanophylla. They were incubated anaerobically with rumen liquor from growing male sheep equipped with a permanent cannula. Cumulative gas production was measured after 3, 6, 12, 24, 48 and 72 hours from the incubation of samples with rumen liquor. PEG was added at levels 15, 30 and 45 mg per 0.2 g dry matter. The chemical analysis showed that the crude protein (%) was 8.2, 9.5, 13.4, for P. lentiscus, C. siliqua and A. cyanophylla, respectively, and that of the ether extracts were nearly the same in all the studied samples. The NDF contents were ranged between 44.5% for C. siliqua and 37% for A. cyanophylla with P. lentiscus lie in the middle (39.8%). The percentages of condensed tannins were 25.4, 21.5 and 4.1 for A. cyanophylla, P. lentiscus and C.siliqua respectively. The average cumulative gas production (ml/0.2 g DM) after 48h of incubation was higher (P<0.05) for C. siliqua then P. lentiscus followed by A. cyanophylla (22.9, 12.6 and 8.2) respectively. Addition of Polyethylene glycol (15, 30 and 45 mg PEG/0.2 g DM) increased (P<0.05) the cumulative gas production compared with control (13.5, 16.4 and 20 vs. 8.4). The current study concluded that PEG can be used to alleviate the undesirable effects of anti-nutritional Polyphenols found in some grazing tree leaves.Ovo je istraživanje provedeno radi ispitivanja djelovanja raznih razina polietilenskog glikola (PEG) na in vitro proizvodnju plina lišća nekog drveća što raste u Istočnoj Libiji. Upotrijebljeni uzorci bili su Ceratonia siliqua, Pistacia lentiscus i Acacia cyanophylla. Uzorci su inkubirani anaerobno s tekućinom iz buraga muških ovaca u porastu s trajno ugrađenom kanilom. Nakupljeni plin mjeren je nakon 3, 6, 12, 24, 48 i 72 sata od inkubacije uzoraka s tekućinom iz buraga. PEG je dodan u razinama od 15,30 i 45 mg na 0,2 g suhe tvari. Kemijska analiza je pokazala da su vrijednosti sirovih bjelančevina iznosile 8.2, 9.5 i 13.4 za P.lentiscus, C.siliqua odnosno A.cyanophylla, a bjelančevine drugih ekstrakata bile su gotovo iste u svim ispitivanim uzorcima. Sadržaj NDF iznosio je 44,5% za C.siliqua i 37% za A.cyanophylla dok je P.lentiscus bio u sredini (39,8%). Ostatci kondenziranih tanina bili su 25.4, 21.5 i 4,1 za A.cyanophylla, P.lentiscus odnosno C.siliqua. Prosječni nakupljeni plin (ml/0,2 g DM) nakon inkubacije od 48h bio je viši(P<0,05) za C.siliqua zatim slijede P.lentiscus i A.cyanophylla (22.9,12.6 i 8.2).Dodavanje polietilenskog glikola (15,30 i 45 mg PEG/0.2 g DM) povisilo je (P<0,05) ukupnu proizvodnju plina u usporedbi s kontrolom (13.5,16.4 i 20 vs.8.4). Prema ovom istraživaanju PRG se može upotrijebiti za ublažavanje nepoželjnog djelovanja antinutritivnih polifenola što se nalaze u lišću drveća za bršćenje

Quiver Theories from D6-branes via Mirror Symmetry

We study N=1 four dimensional quiver theories arising on the worldvolume of D3-branes at del Pezzo singularities of Calabi-Yau threefolds. We argue that under local mirror symmetry D3-branes become D6-branes wrapped on a three torus in the mirror manifold. The type IIB (p,q) 5-brane web description of the local del Pezzo, being closely related to the geometry of its mirror manifold, encodes the geometry of 3-cycles and is used to obtain gauge groups, quiver diagrams and the charges of the fractional branes.Comment: 30 pages, citations adde

Dark quark domains

Formation of stable domains filled with strongly correlated coherent quark matter is discussed in general terms and is exemplified further in the framework of the Generalised Nambu-Jona-Lasinio model. It is argued that such domains, if exist in the Universe, appear dark to an external observer.Comment: LaTeX2e, 5 pages, uses jetpl.cls (included), to appear in JETP Let

Practice of wound closure techniques among emergency physicians and surgeons in Makkah City Hospitals in Saudi Arabia

Background: Wound suturing is a procedure performed by medical and surgical specialists. While there are many different suturing techniques and materials used to treat patients, the choice of which to employ depends on different variables that affect the outcome of the procedure.Design and Methods: This is a cross-sectional study conducted to provide descriptive data regarding the practice of wound closure techniques, and to develop an awareness of scar formation factors. A total of 172 general surgery (GS) surgeons and emergency (EM) physicians in Makkah city hospitals in Saudi Arabia participated in the study.Results: More than 50% of the practitioners favored the simple interrupted technique for the treatment of all types of studied wounds. The other most common techniques among participants were the subcuticular and vertical mattress methods, respectively, while the use of a stapler was limited to certain wound types. Regarding suturing material, polyglycolic acid was the most frequent material used by 50.1% of participants, whereas only 22% of the participants selected nylon material for wound suturing. However, this study showed a good level of awareness among participants, with significant p-values (p&lt;0.05) of strongly agree and agree regarding the essential factors affecting wound healing and scar formation.Conclusions: The result provides insight into the most common suture techniques and materials used in wound closure. There are wide variations in selecting these techniques and materials among the participants. Also, we found that there is good awareness among participants about factors that lead to scar formation

Isolation and characterization of phenol degrading bacterium strain Bacillus thuringiensis J20 from olive waste in Palestine

This study aimed at isolation of phenol degrading bacteria from olive mill wastes in Palestine. The efficiency of phenol removal and factors affecting phenol degradation were investigated. A bacterial strain (J20) was isolated from solid olive mill waste and identified as Bacillus thuringiensis based on standard morphological, biochemical characteristics and 16SrRNA sequence analysis. The strain was able to grow in a phenol concentration of 700 mg/L as the sole carbon and energy source. The culture conditions showed a significant impact on the ability of these cells to remove phenol. This strain exhibited optimum phenol degradation performance at pH 6.57 and 30 C . Under the optimized conditions, this strain could degrade 88.6% of phenol (700 mg/L) within 96 h when the initial cell density was OD600 0.2. However, the degradation efficiency could be improved from about 88% to nearly 99% by increasing the cell density. Immobilization of J20 was carried out using 4% sodium alginate. Phenol degradation efficiency of the immobilized cells of J20 was higher than that of the free cells, 100% versus 88.6% of 700 mg/L of phenol in 120 h, indicating the improved tolerance of the immobilized cells toward phenol toxicity. The J20 was used in detoxifying crude OMWW, phenolic compounds levels were reduced by 61% compared to untreated OMWW after five days of treatment. Hence, B. thuringiensis-J20 can be effectively used for bioremediation of phenol-contaminated sites in Palestine. These findings may lead to new biotechnological applications for the degradation of phenol, related to olive oil production.The authors thank Prof. Charles Greenblatt from Department of Microbiology and Molecular Genetics, Hebrew University – Hadassah Medical School, Jerusalem, Israel for his help.

Diagnostic accuracy of PremaQuick in detection of preterm labor in symptomatic women

Objectives: Failure to identify women at risk of preterm labor (PTL) leads to failure to implement standard measures. This study designed to evaluate the accuracy of PremaQuick test in detection of PTL in women presented with threatened preterm labor (TPTL). Material and methods: One hundred and twenty-two (122) pregnant women, singleton pregnancy, &lt; 37 weeks, admitted with TPTL included in this study, and were compared to 122 controls. After thorough evaluation, participants were examined using sterile vaginal speculum for cervico-vaginal fluid (CVF) sampling, and PremaQuick test. The CVF sampling was followed by trans-vaginal sonographic (TVS) assessment of cervical length (CL). Participants were managed according to hospitals policy thorough their admission, and after discharge in the ante-natal clinics till delivery. After delivery, the delivery data were compared by the recorded participants` data on admission. Results: The PremaQuick test had 95.1% sensitivity, 97.5% specificity, 97.5% positive predictive value, 95.2% negative predictive value, and 96.3% accuracy in detection of PTL. The PremaQuick had significantly higher true negative rate, specificity, positive predictive value, and overall accuracy in detection of PTL compared to CL &lt; 25 mm (p = 0.005, 0.005, 0.01, 0.002; respectively). Conclusions: The PremaQuick is an accurate bedside test in detection of PTL in women presented with TPTL. It had 95.1% sensitivity, 97.5% specificity, 97.5% positive predictive value, 95.2% negative predictive value, and 96.3% overall accuracy in detection of PTL. The PremaQuick had significantly higher true negative rate, specificity, positive predictive value, and overall accuracy in detection of PTL compared to CL &lt; 25 mm

Protein/Creatinine ratio versus 24-hours urine protein in preeclampsia

Objectives: Proteinuria is one of the diagnostic criteria of preeclampsia (PE). Measurement of 24-hour urine protein is the gold standard method for detection of proteinuria in PE. The 24-hour urine sampling is time-consuming, and inconvenient. To evaluate the accuracy of protein/creatinine (P/C) ratio in detection of significant proteinuria ( &gt; 1 g/24-hours urine) in PE. Material and methods: One hundred and ten (110) preeclamptic women were included in this study and admitted for blood pressure monitoring, 24-hour urine collection, fetal well-being assessment and spot urine sample for measuring of P/C ratio. After thorough history and clinical examination, routine antenatal investigations were done for the women included in the study according to the hospital protocol, and to excluded pre-existing chronic renal disease. Twenty-four-hour urine collection started on the morning following hospital admission. Spot urine samples were obtained shortly before the 24-hour urine collection for measuring of P/C ratio. Collected data statistically analyzed to evaluate the accuracy of P/C ratio in detection of significant proteinuria in PE. Results: The P/C ratio of 1.35 ± 2.54 had 94.4% sensitivity, 94.9% specificity, 97.1% positive predictive value (PPV), 90.2% negative predictive value (NPV), and 94.5% overall accuracy in detection of significant proteinuria ( &gt; 1 g/24-hour urine) in PE. Conclusions: The P/C ratio of 1.35 ± 2.54 had 94.4% sensitivity, 94.9% specificity, 97.1% PPV, 90.2% NPV, and 94.5% overall accuracy in detection of significant proteinuria ( &gt; 1 g/24-hour urine) in PE. This study suggests the use of P/C ratio as an alternative to 24-hour urine protein to detect significant proteinuria in PE

Quantum Deconstruction of a 5D SYM and its Moduli Space

We deconstruct the fifth dimension of the 5D SYM theory with SU(M) gauge symmetry and Chern-Simons level k=M and show how the 5D moduli space follows from the non-perturbative analysis of the 4D quiver theory. The 5D coupling h=1/(g_5)^2 of the un-broken SU(M) is allowed to take any non-negative values, but it cannot be continued to h<0 and there are no transitions to other phases of the theory. The alternative UV completions of the same 5D SYM -- via M theory on the C^3/Z_2M orbifold or via the dual five-brane web in type IIB string theory -- have identical moduli spaces: h >= 0 only, and no flop transitions. We claim these are intrinsic properties of the SU(M) SYM theory with k=M.Comment: 46 Page
