New Nickel(II) Complexes with N-donor Ligands and Anions as Coligands. Structures and Optical Properties

The aim of this thesis was the preparation of new Ni(II) coordination compounds with Ndonor ligands and anions as co-ligands. In total, five different ligands were used in the course of this work and these are 2,4,6-Tri(2-pyridyl)-1,3,5-triazine (tptz), Pyridine-2,6dicarboxylic acid (2,6-pda), 4,4'-Bipyridine (4,4-bipy), 2,2'-Bipyridine (2,2-bipy) and 1,10Phenanthroline (phen). All coordination compounds were analyzed by single-crystal XRD and UV-VIS measurements. Almost all coordination compounds described in this work exhibit H-bonding or π−π stacking, in some cases both. The ligands tptz and 2,6pda represent multimodal ligands, which can be of great interest for the production of supramolecules, and were thus extensively used in this work. This resulted in the four new coordination compounds [Ni(tptz)2](BF4)2(H2O), [Ni(tptz)2](I)2(H2O), [Ni(tptz)2](I)2(H2O)2 and [Ni(tptz)2](NO3)2(H2O)7. By using SCN as a co-ligand, the new mixed-ligand complex [Ni(SCN)2(tptz)(H2O)] was obtained. Similarly, a mixed ligand coordination compound [Ni(2,6-pda)(tptz)](H2O)5 resulted from the reaction of both multimodal ligands tptz and 2,6-pda with nickel acetate. 4,4’-bipy was successfully used as a linker ligand in the preparation of the first tptz containing dimeric coordination compound [Ni2(4,4’-bipy)(tptz)2(H2O)4](NO3)4(H2O)2. The use of the 2,2’-bipy isomer yielded the new coordination compounds [Ni(2,6-pda)(2,6-pdaH)]2[Ni(2,2’bipy)2(H2O)2](H2O)6 and [Ni(2,6-pda)(2,2’-bipy)(H2O)](H2O)2. The presence of 2,2’-bipy in [Ni(2,6-pda)(2,6-pdaH)]2[Ni(2,2’-bipy)2(H2O)2](H2O)6 and [Ni(2,6-pda)(2,2’bipy)(H2O)](H2O)2 as a chelating ligand, while 4,4’-bipy is a linker ligand in [Ni2(4,4’bipy)(tptz)2(H2O)4](NO3)4 (H2O)2, is a typical example of the effect of isomers on the type of coordination mode. Phen, which is an N-heterocyclic ligand related to 2,2’bipy, was also extensively used in this work. This resulted in the preparation of [Ni(Phen)3](BF4)2(H2O), [Ni(phen)3](pda)(H2O)11, [Ni(phen)3](I3)2(H2O), [Ni(Cl)(phen)2H2O)](Cl)(H2O)2 and [Ni(2,6-pda)2]2[Ni(phen)2(H2O)2](H2O)9. The novel coordination compound [Ni(2,6-pda)2]2[Ni(phen)2(H2O)2](H2O)9 is the first example of a mixed 2,6-pda/phen ligand system with three crystallographically independent Ni(II) metal centers. The multimodal 2,6-pda ligand acts mainly as a tridentate chelating ligand coordinating in a k N,O,O’ mode to the Ni(II) metal center. In contrast, the 2,6pda ligand in [Ni(phen)3](2,6-pda)(H2O)11 is non coordinating and exists as a counter ion. An attempted synthesis of a bimetallic Ni(II)/Nd(III) complex was not feasible, where only the [Nd(2,6-pda)3][Nd(2,6-pda)(H2O)6](H2O)7 complex was obtained. Interestingly, the 2,6-pda ligand shows both chelating and bridging coordination modes, linking the three Nd(III) metal centers through the oxygen atoms.

Development of Low-Cost Functional Adsorbents for Control of Mercury (Hg) Emissions from Coal Combustion

A range of environmentally advantageous low-cost carbon materials, including pulverized fuel ashes (PFA) and chars derived from different waste streams, were examined as the potential sorbents for use in mercury capture by sorbent injection. The test results demonstrated large variations in mercury retention among the fly ash samples examined, with those generated from burning bituminous coals having the best performance in general. By and large, the mercury retention capacity of fly ash appears to be mainly determined by its unburned carbon content and, to some extent, also by the chemical and morphological properties of its mineral matter. For the char samples examined, it was found that those from the gasification of paper waste materials displayed the best performance. Without any further treatment, the wastepaper-derived char materials outperformed the benchmark Norit-Darco FGD carbon by a factor of 2, in terms of mercury retention capacities. Although steam activation and KMnO4 impregnation can both.

Objective: The aim of the study was to estimate the action atorvastatin(20mg/day) on bone biochemical markers dyslipidemic men. Methodology: This study was conducted between May 2015 and November 2015 in Al-Basrah General hospital in Basra, Iraq, to evaluate important role of atorvastatin (20mg/day)(Lipitor® Pfizer Pharma GmbH.Germany) on bone biochemical markers. Thirty men patients who had been admitted for a variety of medical problems included in the study. All the patients had previously been diagnosed with Dyslipidemia by specialist physician in internal medicine and all patients age below 55 years . the inclusion criteria for the experimental group was use of atorvastatin for at least three months; the study group was then compared to age-matched healthy men . bone biochemical markers were compared between groups. Results are expressed mean ± SD; statistically Student’s t test was used to compare variables. Results: The mean age of the statin group was 44.5 ± 5.9 and control group was 45.7 ± 4.4. After 3 months treatment with atorvastatin, as in table (1) and figures (1-8) Surprisely level of serum total cholesterol remain significantly higher than value of normal healthy group. LDL value significantly reduced by treatment but still significantly higher than values of normal group. HDL value were significantly higher than that of its initial values, but level of HDL ;after treatment; was not significantly different from that of normal group. Triglycerides was not significantly changed by treatment and its value still significantly higher than normal group. Vit D level was not significantly change by treatment and its value was significantly lower than normal group. Osteocalcin was elevated significantly by treatment; and this elevation was significantly as compared with its initial value and with that of normal group. Amino Terminal telopeptide procollagen type I (NTX-I) was not significantly change by treatment and its value still significantly higher than normal group and before treatment values. Also body mass index value was not significantly changed by treatment. Recommendations: Further studies are recommended to confirm the positive effects of atorvastatin and other statins on bone biochemical markers with larger number of patients and longer period of follow up. Also other bone formation and resorption markers are recommended to determine the expected mechanisms of action of statins on bone remodeling processes.
Mixing Behaviors of Jets in Cross-Flow for Heat Recovery of Partial Oxidation Process

Abstract In our previous work, a new technology has been proposed that the cooled synthetic gas (syngas) produced in the partial oxidation process can be used as quenching medium. The mixing of the hot product gas and cold syngas is critical to this new quenching approach. In this work, both experimental measurements and CFD simulations were conducted to study the mixing behavior of the jets in cross-flow (JICF). A mixing apparatus with four jets was set up. Methane was used as the tracing gas and the concentration distribution was measured using an FID detector. The realizable k-ε model was found to give better predictions of the experimental data among the three k-ε models. The effects of jet incident angle θ, jet velocity to mainstream velocity ratio VR and Reynolds number on the mixing behavior were investigated. The results showed that the optimum jet incident angle was 145°. For configuration with jet incident angle smaller than 130°, increasing the velocity ratio VR in the range of 1–3 improves the mixing. When the jet incident angle is larger than 130°, the optimized range of velocity ratio VR is 1.8–2.4. The Reynolds number has insignificant effect on the spatial distribution of mixedness, indicating that the optimum design parameters obtained at low Reynolds number can be used to guide the choosing of industry operating conditions with Reynolds number as high as 3.13×105–6.26×105.
Mechanism of Polymerization During the Solidification of Flyash-based Geopolymers

Geopolymers,with good mechanical properties and resistance to acid attacks,were prepared using(flyash) and kaolin.Geopolymer could be equivalents of the Portland cement products.The mechanism of polymerization was deduced from the analytical data of XRD,IR,SEM,and NMR of the geopolymeric products cured each for 3 days,7 days,14 days,and 28 days,which can be described as follows:(1) the glassy parts of the flyash were dissolved in the high molar alkaline solution and some Si-O,Al-O bonds were broken;(2) at the presence of OH~(-)and Na~(+),these broken bonds formed aluminosilicate gel and then transformed into zeolitic precursors with changing compositions and concentrations of the solution;(3) by dehydration,these(zeolitic) precursors were changed into the amorphous phase materials.NMR analysis indicated that in the geopolymeric products cured for 28 days,Q~(4) was the principal form of Si element.The experimental results provided a good basis for understanding the reactive mechanism of polymerization during processing of geopolymer products.
Evaluation of Seed Bio-priming against Chilli (Capsicum frutescence L.) Diseases in vivo

An experiment was to know the efficacy of various seed bio-priming against chilli diseases in vivo. Chilli (Capsicum frutescence L.) damping-off, anthracnose and fusarium wilt can be common mainly caused by Pythium sp. , Colletotrichum capsici and Fusarium solani. Seed bio-priming of chilli seeds in vivo revealed maximum per cent seed germination 59.4% in P. fluorescens applied at imbibition @10gm/kg and these treatment was also found significantly superior over the rest and also reduce per cent disease incidence damping off, anthracnose and fusarium wilt of chilli by 21.6%, 9.0% and 18.9%, respectively. Seed bio-priming with P. fluorescens applied at imbibition @10gm/kg was also found promoting plant growth activity significantly higher after 10, 20 and 30 days of seed sowing in seedling height, shoot length and root length.
Drying and Rehydration Behaviour of Bamboo (Bambusa bambos) Shoots during Convective Tray Drying

This study investigated the thin-layer drying characteristics of bamboo slices in a convective tray dryer with three different temperatures viz., 75, 80 and 85°C. Four mathematical models were investigated for describing the thin-layer drying behaviour of bamboo shoot slices. The performance of these models was investigated by comparing the coefficient of determination (R2), reduced chi-square (c2) and root mean square error (RMSE). All the four models showed good fit but Page model reflected the drying mechanism at 80°C temperature the better. The drying air temperature had the significant effect on the drying kinetics of bamboo shoot slices. Effective moisture diffusivity varied from 4.22×10-12 to 5.56×10-12 m2/s over the temperature range studied, with an activation energy of 28.60 kJ/mol. Rehydration ratio elevated when the salt solution used for rehydration and the weight gain was more irrespective of temperature. Superior rehydration was noticed when the slices were dried at 80°C, and it was relatively poor at 85°C and 75°C.
Vacancy durations : search or selection?

In van Ours and Ridder (1992), the authors showed that employers use a nonsequential search strategy when filling job vacancies. In this paper, they explicitly decompose a vacancy duration into an applicant period and a selection period. The authors formulate a simple theory for the determination of the application period. By making some distributional assumptions, they obtain estimates of the average application and selection period. The authors conclude that vacancy durations are devoted to selection.

R-25788 Effects on Chlorsulfuron Injury and Acetohydroxyacid Synthase Activity

Chlorsulfuron {2-chloro-N-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino] carbonyl]-benzenesulfonamide} applied preemergence or postemergence as a soil drench retards the growth of four corn (Zea mays L.) genotypes in soil with 50% inhibition in each case at a rate of approximately 5 g ai/ha. R-25788 (N,N-diallyl-2,2-dichloroacetamide), applied at 1.0 kg ai/ha to the soil preemergence with chlorsulfuron or postemergence 2 days prior to chlorsulfuron treatment, reverses shoot growth inhibition induced by the herbicide in varying degree in ‘XL25A’ and ‘XL72B’ corn hybrids and ‘FRM017’ and ‘FR619’ inbreds, but not in soybean [Glycine max (L.) Merr. , var. ‘Amsoy-71’]. Under similar conditions, flurazole [2-chloro-4-(trifluoromethyl)-5-thiazolecarboxylic acid (phenylmethyl ester)] and CGA-92194 [α-(1,3-dioxolan-2-yl-methoxy)-imino-benzeneacetonitrile] are less effective than R-25788 in protecting corn genotypes from chlorsulfuron injury. R-25788 also partially reverses chlorsulfuron-induced root growth inhibition in XL25A and FR619 corn but not in pea (Pisum sativum L. var. ‘Dwarf Gray Sugar’). Acetohydroxyacid synthase (AHAS) is higher in both activity and the proportion that is very sensitive to in vitro chlorsulfuron inhibition when prepared from XL25A shoots than from the roots. R-25788 does not reverse the in vitro inhibition of corn acetohydroxyacid synthase (AHAS) by chlorsulfuron. Pretreatment of 5-day-old XL25A corn with R-25788 at 24 or 48 μM significantly increases AHAS activity by approximately 25% in both shoots and roots but does not change its in vitro sensitivity to chlorsulfuron. This antidote also increases the glutathione (GSH) content in roots and etiolated shoots. The R-25788-induced elevation of AHAS activity may contribute to its antidotal effect in corn.
How does the COVID-19 pandemic affect housing prices in China?

COVID-19 was first reported in Wuhan in late December 2019, and then spread throughout China, which has had great influence on many aspects of the economy. This paper uses the two-way fixed effects model to investigate the non-linear relationship between the death toll of COVID-19 and the changes in housing prices using monthly panel data from November 2019 to May 2020. The results suggest that there is a U-shaped relationship between monthly death toll of COVID-19 and the percentage changes of housing prices in cities. In addition, the housing markets of New First-tier cities are more sensitive to the COVID-19 pandemic than Second and Third-tier cities, which the pandemic has had little effect on. Similarly, monthly confirmed cases of COVID-19 come to the same conclusions.
Physico-chemical changes during development of safeda guava fruit.

Guava fruits of the variety Safeda (Allahabad) were examined at 10-day intervals during initial growth and at 5-day intervals during ripening in 1964-66 for physical and chemical changes during development. The period from fruit set to full ripe stage was covered. The growth curve as shown by fruit weight was of sigmoid type. Fruit length-width ratio, specific gravity, colour and firmness showed marked changes during development. Soluble solids, sugars, titratable acidity, ascorbic acid and total pectins showed peaks just before fruit drop. All chemical constituents showed consistent patterns of change during fruit development suggesting several discrete physiological stages; viz., prematuration, maturation, ripening and senescence.
Density, Speed of Sound, and Refractive Index Measurements for the Binary Mixture (1, 4‑Dioxane + Isobutyric Acid) at T = (295.15, 298.15, 301.15, 304.15, 307.15, 310.15, and 313.15) K

Density, speed of sound, and refractive index for the binary mixture (1,4-dioxane (1) + isobutyric acid (2)) were measured over the whole composition range at temperatures T = (295.15, 298.15, 301.15, 304.15, 307.15, 310.15, and 313.15) K and at the atmospheric pressure. From the experimental data, excess molar volume VE, excess isentropic compressibility κSE, excess speed of sound cE, excess refractive index nE, molar refraction R, and deviation in molar refraction ΔR were calculated. These results have been fitted to the Redlich–Kister polynomial equation. The excess molar volume, excess isentropic compressibility, and deviation in molar refraction were found to be negative, whereas excess speed of sound and excess refractive index were found to be positive for all temperatures. The thermodynamic properties have been discussed in terms of nature of molecular interactions between the components of the mixture.
Closure of "Longitudinal Dispersion in Sinuous Channel with Changes in Shape"

Results are presented from a series of laboratory experiments conducted on a large scale channel with sinuous planform geometry. These have been used to obtain the magnitude of the longitudinal dispersion coefficient. A constant trapezoidal cross section and a variable cross-sectional "natural" shape under different discharges have been studied. Temporal concentration distributions recorded for the trapezoidal section tend towards Gaussian form and provide values of a longitudinal dispersion coefficient comparable with previous similar studies. The more "natural" cross-sectional geometry channel exhibits strongly skewed distributions and increases the value of a longitudinal dispersion parameter by over 150%. Variation of a longitudinal dispersion coefficient with discharge has been observed and has been explained by the effects of the longitudinally varying cross-sectional shape. A comparison between observed and predicted distributions from a simple routing procedure emphasizes the need for an improved method for incorporating the effects of longitudinal variations in cross-sectional shape.
An experimental study of the load and heat influence from combustion on engine friction

The friction power losses of a turbo-charged heavy-duty diesel engine of the 13 litre class are investigated both by fired engine tests as well as by pressurized motoring tests. During pressurized motoring compressed air is applied to the engine intake which creates loads comparable with fired operation but without the strong and changing thermal influence of combustion. By using this combined approach the influence of the load and the thermal influence of the combustion can be studied separately for the first time. It is found that pressurized motoring yields comparable but generally a bit higher friction power losses as in fired operation. In particular, for full load operation, the agreement between the two methods is very good which supports the reasoning that for full load operation the mechanical load is the dominant factor for the friction power losses. However, for part load operation significant differences arise. Without the thermal influence from combustion, increasing the load on the engine leads to a rather linear increase in the friction power losses as is seen from pressurized motoring. This is in contrast to the fired engine tests, where the friction power losses stay almost constant over a rather large range of part loads and only increase for full load operation. It is argued that the reason for this different behaviour is the thermal impact from combustion.

Elastic constants of glasses in the system P2O5-Na2O-ZnO

The elastic moduli of five different compositoins of the P 2 O 5 -Na 2 O-ZnO glass system were measured using an ultrasonic pulse-echo method. The variations in elastic constants are attributed to the structural changes occurring with the change in composition. In addition to the elastic moduli, Debye temperature, density, molar volume, microhardness and acoustic impedance of these glass samples are also reported
