(R1992) RBF-PS Method for Eventual Periodicity of Generalized Kawahara Equation

In engineering and mathematical physics, nonlinear evolutionary equations play an important role. Kawahara equation is one of the famous nonlinear evolution equation appeared in the theories of shallow water waves possessing surface tension, capillary-gravity waves and also magneto-acoustic waves in a plasma. Another specific subjective parts of arrangements for some of evolution equations evidenced by findings link belonging to their long-term actions named as eventual time periodicity discovered over solutions to IBVPs (initial-boundary-value problems). Here we investigate the solution’s eventual periodicity for generalized fifth order Kawahara equation (IBVP) on bounded domain in combination with periodic boundary conditions numerically exploiting mesh-free technique called as Radial basis function pseudo spectral (RBF-PS) method

Currencies analysis based on stability using apriori-algorithm

This paper presents the stability of currency that is more stable with respect to other currencies. Various currencies are studied and graphs are plotted with reference to dates on a yearly basis and analyze its patterns. The stability of a currency was determined by using Apriori-algorithm. This algorithm maneuver in continues manner unless the desired results are achieved.

Multi-organ dysfunction secondary to yellow scorpion sting

Scorpion stings are common in tropical and subtropical regions. The history and clinical manifestation warrant urgent recognition and treatment. The incidence of scorpion stings in Pakistan is not known as there is no published data available in literature. We report our experience of a yellow scorpion sting victim who required intensive care admission after developing multi-organ dysfunction

Hydrido/chloroaluminium alkoxides and metal (Al, Ge) alkoxides-synthesis, characterization and applications for preparation of novel hydrogen storage nano-materials

In first part of this work, efforts are made to prepare structurally characterized molecular compounds of the general formulae [HnAl(OR)3-n]x (n = 2 {1, 2, 5}, 1 {3, 6} or 0 {4, 7}; x = 2 {5, 6 7}, 4 {4}, 5 {1} or ∞ {2, 3}; R = cHex {1-4} or cHexMe 1 {5-7}), [ClAl(H)(OR)]2 (R = cHexMe 1 {8}), [ClnAl(OR)3-n]2 (n = 1 {9} or 2 {10}; R = cHexMe 1 {9-10}), [Ge(OR)2]2 (R = cHex {11} or cHexMe 1 {12}, iPr {13}); [HAl(OR)(NR\u27)]2 (R = tBu {14}, cHexMe 1 {15; R\u27 = SiMe3 {14-15}). The molecular compounds 1, 2, 4, 5, 7, 8 - 12, 14 and 15 are obtained as crystalline powders and characterized by single crystal X-ray analysis as well as 1H, 13C NMR and IR spectroscopy. Crystals suitable for X-ray analysis could not be grown for compound 3, 6 and 13. However, these compounds were characterized by NMR and IR spectroscopy. Molecular compounds containing Al as central metal atoms were also characterized by 27Al NMR spectroscopy. The elemental compositions of all compounds were determined by CHN analysis as well as by other complexometric titration techniques wherever suitable. In the second part of this thesis, the results of hydrogen adsorption studies with Al/Al2O3-composite nano-wires (NWs) and Ni/Al2O3-composite nano-powders (NPs) using a modified Sievert apparatus are presented. Al/Al2O3-composites were prepared as thin films by the decomposition of a molecular precursor, [H2Al(OR)]2, both upon steel as well as glass substrates in a cold wall CVD reactor. Ni/Al2O3-composites were prepared as powders by the decomposition of Ni(acac)2 under a steady stream of [H2Al(OR)]2 in the same CVD set up, using an adapted sample holder. Both types of materials, Al/Al2O3 NW and Ni/Al2O3 NP, were characterized by XRD, SEM, TEM, EDXS, SAED and IR spectroscopy. Volumetric hydrogen storage measurements with variable temperature and pressure showed a maximum hydrogen uptake of 6.5(±0.2)wt.% with Al/Al2O3-composite NWs. The adsorption kinetics was followed by DSC and IR spectroscopy. The adsorption of hydrogen at the Al/Al2O3-composite NWs is controlled by pure physisorption at temperatures below 100°C while above 100°C, desorption occurs as a result of increasing temperature.Im ersten Teil der Arbeit werden Versuche zur Synthese und strukturellen Charakterisierung von molekularen Verbindungen der allgemeinen Formeln [HnAl(OR)3-n]x (n = 2 {1, 2, 5}, 1 {3, 6} or 0 {4, 7}; x = 2 {5, 6 7}, 4 {4}, 5 {1} or ∞ {2, 3}; R = cHex {1-4} or cHexMe 1 {5-7}), [ClAl(H)(OR)]2 (R = cHexMe 1 {8}), [ClnAl(OR)3-n]2 (n = 1 {9} or 2 {10}; R = cHexMe 1 {9-10}), [Ge(OR)2]2 (R = cHex {11}, cHexMe 1 {12}, iPr {13}); [HAl(OR)(NR\u27)]2 (R = tBu {14} or cHexMe 1 {15; R\u27 = SiMe3 {14-15}) beschrieben. Die molekularen Verbindungen 1, 2, 4, 5, 7, 8 - 12, 14 und 15 werden als kristalline Pulver erhalten und durch Einkristallröntgenstrukturanalyse sowie 1H, 13C NMR- and IR-Spektroskopie charakterisiert. Für die Verbindungen 3, 6 and 13 konnten keine für die Röntgenstrukturanalyse brauchbaren Einkristalle erhalten werden. Molekulare Verbindungen mit Al als Zentralatom wurden mittels 27Al NMR-Spektroskopie untersucht. Diese Verbindungen wurden allerdings durch NMR- und IR_Spektroskopie charakterisiert werden. Von allen Verbindungen wurden Elementaranalysen angefertigt. Wo möglich wurden komplexometrische Titrationen zur Metallgehaltsbestimmung durchgeführt. Im zweiten Teil der Arbeit werden die Wasserstoff-Absorption von Al/Al2O3-kompositären Nano-Drähten (NWs) und Ni/Al2O3-kompositären Nano-Pulvern (NPs) mit einer modifizierten Sievert-Apparatur präsentiert. Al/Al2O3 Komposite wurden als dünne Schichten durch die Zersetzung einer molekularen Vorstufe, [H2Al(OR)]2, auf Stahl und Glas-Substraten in einem Kaltwand-Reaktor erzeugt. Ni/Al2O3-Komposite wurden als Pulver durch die Zersetzung von of Ni(acac)2 unter einem stetigen Fluss von [H2Al(OR)]2 in der selben CVD-Apparatur, allerdings mit angepasstem Substrathalter gewonnen. Beide Materialtypen,Al/Al2O3 NW and Ni/Al2O3 NP, wurden durch XRD, SEM, TEM, EDXS, SAED and IR-Spektroskopie charakterisiert. Volumetrische Wasserstoff-Speicher Untersuchungen mit variablem Druck und variabler Temperatur zeigten eine maximae Wasserstoff-Aufnahme von 6,5(±0.2)wt.% für Al/Al2O3-Komposit NWs. Die Absorptions-Kinetik wurde mittels DSC und IR-Spektroskopie verfolgt. Die Waserstoof-Aufnahme der Al/Al2O3-Komposit NWs ist unterhalb von 100°C durch reine Physisorption bestimmt, während über 100°C aufgrund der steigenden Tempertur Desorption vorherrscht

Anaesthesia at remote location: use of modified Bain circuit (Mapleson D) at Kunri Christian Hospital (KCH)

OBJECTIVE: To develop a safe general anaesthesia technique for remote areas with lack of facilities. METHODS: Four types of anaesthesia techniques using TIVA and modified Bain circuit were planned. Monitoring facility was limited to manual sphygmomanometer, palpation of radial pulse and monitoring of colour of skin and blood. Depth of anaesthesia was assessed using EVANs, RPST scoring system. Patients were asked in recovery room for awareness. RESULTS: Surgeries done were cesarean sections, laparotomies, gynaecological, urological, hernia and burn contractures. Six patients had RPST score of 5 or more and three patients in recovery room complained of awareness. Cost per Anaesthesia was Rs225. CONCLUSION: TIVA with modified Bain circuit provided effective anaesthesia in remote area at low cost
