Adsorption of Remazol Birilliant blue R dye (RBBR) from aqueous solutions on
activated carbon prepared from coconut shell was compared, and where coconut shell
was investigated in terms of adsorbent dose, dye concentration, temperature, and pH.
The results were compared for all parameters. The equilibrium adsorption
data were interpreted using Langmuir, Freundlich, and Temkin models. The
adsorption of of RBBR dye was better represented by the Freundlich equation.
The change in the thermodynamic parameters, like standard free energy (ΔG°),
standard enthalpy (ΔH°), and standard entropy (ΔS°) of the adsorption process were
calculated, from the results show adsorption process was endothermic.

Semiemperical calculations were performed on some compounds of the three
types of Diels-Alder reactions,normal,neutral and inverse electron demand reactions.
Bivariate and partial correlation matrices ,and multivariant correlation between log
k(k,rate constant collected from literature) and the calculated quantum descriptors.
Also the data were subjected to ridge regression to obtain models with better
predictive power and to reduce correlation among predicator variables.

Quantitative Structure–Property Relationship (QSPR) models method have
been used for the prediction intrinsic viscosity of (poly ethylene oxide) in solution.
Several models for the prediction of intrinsic viscosity have been drawn up by using
the multiple regression technique. Penta models with R2 ranges from 0.87-0.99 by
using MLR based on descriptors calculated from molecular structure have been
developed present in this study. The results show excellent model with high
correlation coefficient, minimum standard of error by using five parameters, which
indicate that these parameters Total Energy T.E, capacity heat of organic solvent Cp(s),
Van Der Waals Area V.W.AREA, The energy of Highest Occupied Molecular Orbital
HOMO and The energy of Lowest Unoccupied Molecular Orbital LUMO, play an
important role in effect on intrinsic viscosity of polymer in these solvents .

The synthesis of dinuclear transition metal(II) macrocyclic dithiocarbamate
complexes and there characterisation are reported. The dithiocarbamate complexes
were prepared via a one pot reaction by mixing the secondary amine {N1,N4
dibenzhydrylbenzene-1,4-diamine}, CS2, KOH, and metal chloride. The modes of
bonding and overall geometry of the compounds were determined through
physicochemical and spectroscopic methods; elemental analysis, FTIR, UV-Vis,
magnetic susceptibility, conductance, melting points, mass spectroscopy and 1H-, 13C
, DEPT, 1H- 1H COSY, 1H- 13C HQMC NMR spectroscopy. These studies revealed
the formation of dimetal bisdithiocarbamate complexes of the general formula
[M(L)]2 with tetrahedral geometry about Co(II) and Ni(II) atoms. However, square
planar geometries have been suggested for Cu(II) complex in a solid state but its
exhibited octahedral ina liquid states.

The ligand 2,2◌-(Terephthaloyl) bis (azanediyl) bis (3-mercapto propanoic acid)
(TAMPA) was synthesized from the reaction of terephthaloyl chloride with cysteine, it
has been characterized and its structure was elucidated depending upon elemental
analysis (CHNS) and spectral data (IR , UV-Vis) . Series of metal complexes of the
deprotenated ligand with ions such as Mn(II) , Co(II) , Ni(II) , Cu(II) and Zn(II) have
been synthesized and characterized by (FT-IR) , (UV-Vis) spectroscopy , flame atomic
absorption technique, magnetic susceptibility and conductivity measurements. The
following general formula were suggested [M2(TAMPA)(H2O)4] .

New series view of ethyl2-(pyridin-2-ylamino) acetate compounds were
synthesized by react 2-amino pyridine with ethyl chloro acetate and KOH, then the
ethyl2-(pyridin-2-ylamino)acetate react with hydrazine hydrate (99%)to give 2
(pyridin-2-ylamino)acetohydrazide[2], which the 2-(pyridin-2-ylamino)
acetohydrazide treated with different substituted aromatic aldehydes formed various
substituted arylidine derivatives [3a-d]. These arylidine derivatives on treatment with
triethyl amine and chloroacetyl chloride yielded different azetidine derivatives [4a
d].Reaction of 2-aminopyridin with different aromatic aldehyde and CuCN formed
various substituted cyanic [5a-c] .Reaction of [5a-c] compound with NaN3,NH4Cl and
DMF afford tetrazole derivatives [6a-c].Also 2-amino pyridine reacted with 2
mercaptobenzoxazole,2-mercaptopyrimidin and 2-mercapto benzo thiazole to give the
new derivatives of compounds[7,8,9].The molecular structure were characterized by
FTIR,1HNMR.

2-(3-(tert-Butoxycarbonylamino)propyl)-5-methylthiophene and its 4-deuterio
derivative have been synthesized by a simple and convenient method in a six step
sequence from 2-methylthiophene. The final step involved bromine-lithium exchange
on 4-bromo-2-(3-(tert-butoxycarbonylamino)propyl)-5-methylthiophene at low
temperature in anhydrous tetrahydrofuran followed by treatment with water or D2O.

The study was conducted in Ninava governorate to show the evaluation of
oxidants, antioxidants and some biochemical parameters in vegetarianisms and ova
lacto vegetarianisms parameters which include: vitamin E, vitamin A, β-carotene,
vitamin C, ceruloplasmin (Cp), total protein, albumin, calcium, total bilirubin, uric
acid, creatinine, total iron binding capacity (TIBC), iron, glutathione(GSH),
malondialdehyde (MDA), peroxynirate (ONOO-), cholesterol, glucose, glutathione
S-transferase (GST) . The study included (182) persons represented in three groups
(Male and nonsmokers): the first group as a vegetarianism (54), the second group
represented for ova-lacto vegetarianisms (62) and the three group omnivores (Non
vegetarianisms) (66) .
The results showed a significant increase in vegetarianisms in comparison
with non-vegetarianisms for: vitamin E, vitamin A, β-carotene, vitamin C, total
protein, albumin, calcium, TIBC, GSH and glucose. While a significant decrease in
total bilirubin, MDA, ONOO-, cholesterol, GST and body mass index(BMI). The
results also showed a significant increase of ova-lacto vegetarianism in: vitamin E, β
carotene, vitamin C, GSH and glucose when compared with non-vegetarianisms.
While a significant decrease in: Cp., total protein, calcium, TIBC, MDA, ONOO-,
GST and BMI. On the other hand, the results revealed a significant increase of
vegetarianism most antioxidants when compared with ova-lacto vegetarianisms, while
a significant decrease in oxidants compounds
In conclusion, vegetarianisms and ova-lacto vegetarianisms persons had an
increase (Vegetarianism Especially) antioxidants levels compared with omnivores
leading to a decrease in their oxidative stress, disease and its complication from
oxidants.
