The wastewater resulting from slaughtering and meat processing in slaughterhouses contains a high amount of organic matter. The discharge of these wastewaters into rivers, sewage networks or soil creates significant environmental pollution. In the present study, the treatment of wastewater from Erbil cattle and poultry slaughterhouse through an electrochemical coagulation method has been investigated. In experimental studies, the effects of current density, initial pH, and support electrolyte concentration (Na2SO4) on chemical oxygen demand (COD) removal efficiency have been investigated. Through numerous treatment investigations with main slaughterhouse wastewater samples, the aluminum electrodes exhibited a removal efficiency of 82.43%. at an electric current density of 20.00 mA/cm2 and pH 5. While by using iron electrodes a COD removal efficiency reached 92.52% at an electric current density of 20 mA/cm2 and pH 9. Despite the electrocoagulation (EC) lower COD, the system's effectiveness cannot be evaluated without taking the toxicity into account. for such cases, Microtox evaluations were done for the most efficient COD removal level. The electrocoagulation technique was shown to lower both toxicity and COD. As a result, it has been found that EC with iron and aluminum electrodes is an appropriate technique for treating slaughtering wastewater containing high levels of organic contaminants in terms of COD reduction and toxicity minimization.

This study deals with the comparison of Theoretical Sunshine Hours (TSH) and Actual Sunshine Hours (ASH) in different meteorological stations in Iraq, and its relation to climatic factors (Maximum Air Temperature, Relative Humidity and Wind Speed), during the period between 1979 and 2019. The results indicate that the lowest monthly value of theoretical sunshine hours (TSH) was obtained at Mosul Station for the month of December with a value of 9.57 hours and the lowest monthly value for actual sunshine hours (ASH) was obtained at Mosul Station for the month of January with a value of 4.5 hours. The maximum monthly value of theoretical sunshine hours (TSH) at Mosul station for the month of June was obtained as 14.43 hours, and the maximum monthly value of actual sunshine hours (ASH) at Rutba station for July was obtained as 12.4 hours. The average annual values of theoretical sunshine hours (TSH) ranged between 11.77 hours - 12.15 hours, while the average annual values of actual sunshine hours (ASH) ranged between 8.19 hours - 9.19 hours. Simple regression equations were reached at the various study stations between theoretical and actual hours of sunshine and different climatic factors.

One hundred ear swabs were collected from patients attending Hawija
General Hospital, Azadi Teaching Hospital, and outpatient clinics in
Kirkuk Governorate, for ages ranging between 2-45 years, During the
period from October 27, 2022 to January 3,2023. The results showed
that 91(91%)of samples have positive growth on MacConkey , mannitol
and blood agar. While the remaining samples 9 (9%) had no growth.
The samples that showed positive bacterial growth were identified as
139 isolates. The number of Gram positive isolates was 91(65.5%),
while the number of negative isolates was 48 34.5%. The isolates were
identified by routine biochemical tests, and the diagnosis was confirmed
by Vitek2 compact system device. The percentage of isolated bacterial
species were Staphylococcus aureus 34.53%, Staphylococcus epidermidis 22.30%, Proteus mirabilis 8.63%, Morganella morganii 6.47%,
Enterobacter sakazakii 6.47%, Staphylococcus saprophyticus 4.32%,
E.coli 3.60%, Klebsiella pneumonia 3.60% and each of Kocuria kristinae,
Proteus vulgaris, Comamonas testosterone 2.88%, and Staphylococcus
lentus 1.44%. The results of the sensitivity test to ten types of antibiotics,
namely Amikacin, Ceftazidime, Nitrofurantion, Imipenem, Azithromycin,
Tetracycline, Cefotaxime, Tobramycin, Ofloxacin, Oxacillin, showed
that all isolates were 100% resistant to the antibiotics Cetazidime and
Cefotaxime, while they showed varying resistance to the rest of the
antibiotics. Antibiotics: All isolates showed 100% sensitivity to Antiimipenem

The isoscalar giant dipole resonance (ISGDR) of the even-even Tin
isotopes 112,114,116,118,120,122,124Sn has been investigated by using fully
self-consistent quasiparticle random phase approximation (QRPA)
based on Bardeen Cooper Schriffer-Hartree Fock (HF-BCS). We depend
on five sets of Skyrme-type interactions (T5, SKM, SLY4, SGII, and SKX)
with varying effective mass m ∗/m and nuclear matter incompressibility
coefficient KNM. Furthermore, the calculations incorporate the effects
of several pairing force types, such as volume, surface, and mixed.
The calculated strength distributions, scaled energies Es
, constrained energies Econ, and centroid energies Ecen of the ISGDR for the
investigated isotopes are compared with the available experimental data.
Analysis is done on the relationships between KNM and m ∗/m, and the estimated properties.

In this study, Four types of vegetables were collected from Erbil city of
Iraq, some grown locally and some imported. The vegetables they studied were Pepper (Capsicum annuum), Eggplant (Solanum melongena),
Tomato (Lycopersicon esculentum), and Zucchini (Cucurbita pepo),
which are commonly found both locally and imported. Additionally, they
looked at 3 local vegetables: Radish (Raphanus raphanistrum), Cress
(Lepidium sativum), and Parsley (Petroselinum crispum). They collected
12 samples of each vegetable from the Erbil market The heavy metals
found in vegetables, such as silver (Ag), aluminum (Al), cadmium (Cd),
chromium (Cr), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), zinc
(Zn), and arsenic (As), were examined using inductively coupled plasma
(ICP). To identify health problems, the following metrics were calculated:
carcinogenic risks (CR), daily intake (DI), and target hazard quotient
(THQ). The majority of veggies generally had metal levels that were
under daily dietary guidelines. The amounts of cadmium and silver
in imported pepper, local and imported eggplant, imported zucchini,
imported tomatoes, radish, cress, and parsley were greater than those
deemed safe for daily use. There may be health dangers associated
with this. These veggies were determined to be unhealthy when we
examined several health hazard indices.

An estimated 12–20% of couples struggle with infertility, It is described
as not becoming pregnant after a year of trying. About one-third of
these couples are infertile because of female factors, and another third
are infertile because of male factors. A combination of the two may
be experienced by couples in the remaining one-third. Its distributed
into two groups, primary and secondary. A total of 60 participants,
30 of whom were older women (>35) and 30 of whom were younger
women (<35). In this study the results were showed statistically highly
significant positive correlation-r between GH and both serum and
follicular fluid (FF) FSH (0.84, 0.81 mIU/ML), LH (0.76, 0.74 mIU/ML)
and AMH (0.89, 0.86 mIU/ML), and there was highly significant positive
correlation between GH and number of retrieval Oocyte (0.47, 0.46
mIU/ML), negatively significant correlation was found between GH and
number of abortion (-0.10, -0.14 mIU/ML). Notably, the vast majority
of the assessments GH hormone levels in serum and follicular fluid
revealed a statistically significant positive correlation with FSH, LH, AMH,
the frequency of miscarriages, the retrieval of oocytes and infertility
duration. These findings imply a strong positive correlation between GH
and female fertility. As a result, much research is required to assess,
estimate the importance of GH levels on women’s fertility, and to get
an early hormone level assessment before beginning a GH-containing
therapy program
