TAZKIYATUN NAFS CURRICULUM DEVELOPMENT IN JUNIOR HIGH SCHOOL (Analysis of Concepts Tazkiyatun Nafs by Ahmad Anas Karzon and its Implementation in Junior High School)
Authors: Mursalin Hisan
Published: January 2020

Islam considers that education is not only as a process of transfer and transformation of knowledge naturally, but also a mandate that aims to make students to be a person who has divine personality (robbani), good moral and makes his life be more qualified due to the increase of spirit of faith in his soul; worthwhile both in the world and in the hereafter for him. Purification of soul or Tazkiyatun nafs is very important in the life of a human being. The soul determines whether an action is good or bad because a clean soul will produce taintless behavior while a bad soul will produce bad behavior and morals.This is certainly related to the tazkiyatun nafs concepts which have been explained by the scholars in which the concept of purification of soul is a spiritual need in the form of the teaching of din (Islam), tarbiyah, and tazkiyah for the soul. The human orientation today that prioritizes material does not guarantee the happiness of life. Facts have spoken that life's confusion and mental drought have mushroomed everywhere.The purpose of applying the concept of tazkiyatun nafs to the education is to lead the formation of a noble Muslim figure, with the same educational goals; human perfection in terms of taqarrub (to closer) to Allah, and happiness in  the world and the hereafter. While the difference is when education is oftentimes merely taught without any guidance and direction in carrying out the morality or worship taught. Therefore, current education should do the soul purification at first so as the worship performed imprints on human heart and behavior.The focus of the problem in this study is to develop the Tazkiyatun Nafs curriculum appropriate with the age of junior high school students. Development of the curriculum is focused on developing goals, materials, methods, learning techniques, evaluation techniques, patterns of interaction and its implementation in everyday life. In conducting this research, the writer applied field study type since the data needed to compile scientific work was obtained from the research field. The research used a qualitative approach aimed at understanding social phenomena from the view of or perspective of participants. The Participants were those who were invited to interview, observed, asked to provide data, opinions, thoughts and perceptions. In terms of the presentation of material was descriptive analysis because this study attempted to sharpen the analysis of the full description related to the concept of tazkiyatun nafs which was then implemented to junior high school students.The result of the observation about the implementation of the tazkiyatun nafs curriculum at Darussofa IT Junior High School showed that the implementation of curriculum in everyday life needs to be taken into account by fostering the inner piece experienced by students so that a sense of being watched by Allāh ﷺ will be grown.

Authors: Dumitru Gabriela , Ciornea Elena Todirascu , Sandu Ion
Published: January 2020

In recent years, commercial glyphosate herbicide formulations have been widely used in agriculture to control aquatic and terrestrial weeds. These pesticides may result in disruption of ecological balance, causing damage to nontarget organisms, including fish. Carassius auratus L. specimenes were exposed to glyphosate herbicide in concentration of 2.5mg/L and, respectively, 5 mg/L for 120 h, in laboratory condition. Thus, the effects of this chemical agent on both hematological parameters (hemoglobin, hematocrit, number of red blood cells) and on oxidative status indices (SOD, CAT, GPX, MDA) at Prussian carp experimental lots were analyzed. Our results showed, in comparison with the reference batch, the influence of glyphosate on the analyzed hematological and biochemical parameters, in close correlation with the administered pesticide dose.

In order to solve and clarifying certain aspects of the clay content (particles [0.002 mm) sands and sandy soils, humus, respectively, the process of bioaccumulation and mineralization the organic matter of the land, in the Research and Development Centre for Plant Growing on Sand Dabuleni, have initiated research aimed at finding methods and means for accumulating and thus the increase in the content of clay in the soil, respectively humus.Therefore, to improve radical of sandy soils, we found it necessary to resort to what is called loess process. It consists in enriching the horizon the surface soil (20-25 cm) the fraction with 8-10% clay, to 1.5-5%, as currently it contains. It is primarily intended to influence various amounts loess material on physical, hydro- physical and chemical properties of soils, then the plant response to changes products in the soil, increasing the guaranteed potential fertility of these soils, which will result in production high and constant.Obtaining appropriate agricultural production on sandy soils (eutric psamosol) it is limited not only by the soil, but also other factors such as relief, drainage and even climate. Because coarse texture, water-holding capacity in the case of sandy soils it is very low in all soils, the clay content below 5% production capacity of soils it is particularly low in the absence of agropedoameliorative measures and especially irrigation. Wind erosion occurs in all perimeters sandy soils, with higher intensity is observed in Oltenia Plain (Dabuleni Field).
Titanium Influence on the Microstructure of FeCrAl Alloys Used for 4R Generation Nuclear Power Plants
Authors: Geanta Victor , Voiculescu Ionelia , Stefanoiu Radu , Jianu Adrian , Milosan Ioan , Stanciu Elena Manuela , Pascu Alexandru , Vasile Ion Mihai
Published: January 2020

4R generation nuclear power plants should work with metallic material of the highest quality, capable to resist in maximum safe conditions for 25-30 years. FeCrAl alloys are capable of such performance, because of the resistance to: oxidation at high temperatures, corrosion, erosion and penetrating radiations in liquid metal environments. In addition, such materials are capable of forming on their surface some oxide layers, textured and self-renewable, with high adhesion to metallic substrates. These properties can be improved by microalloying with metal elements such as Ti, Zr, Y, Hf in amounts of 1 to 3%. These chemical elements have high affinity to oxygen, being able to stabilize the structure of the superficial layer of oxide (alumina) and to increase adhesion to the metallic substrate. The FeCrAl alloys microalloyed with titanium were obtained in a VAR (Vacuum Arc Remelting) equipment in argon atmosphere (99.99% purity). There were obtained three batches microalloyed with 0.5%, 1% and 1.5% titanium, preserving the same Fe-14Cr-5Al metal matrix. In order to determine the chemical composition of the oxide layer and of the sample bulk, the EDAX analysis was performed. Microstructural features were revealed using SEM analysis. The results showed the capacity of the FeCrAl alloy to form oxide layers, with different textures and rich in elements such as Al and Ti. The compositional analysis performed on FeCrAl samples microalloyed with 0.5, 1.0 and 1.5% Ti in the central zone shows a relatively similar composition compared to the technological calculations made, reflecting the homogeneity of the alloy. The microhardness measurements performed on the cross sections of the metallic samples attest values in the range 163-183 HV0.2, falling within the normal range for these materials. These values are influenced by the presence of the alloying elements in the metallic matrix and by the homogeneous arrangement of constituents.

Authors: Dinu Cornel , Zaharia Sorin Eugen , Pietreanu Casandra Venera
Published: January 2020

On-ground de-icing activity represents a need to protect the aircraft under low-temperature operating conditions, with a high degree of saturation of suspended water vapor or in precipitation conditions that may favor depositions on aircraft surfaces. This activity determines the use of de-icing and anti-icing agents in significant quantities, which leads to compliance with environmental protection standards. In this paper the authors identify solutions for the management of the residues resulting from de-icing activities that lead to soil contamination with different chemical compounds from the fluids used for de-icing.

Published: January 2020

Aldolase (ALD) (fructose-1,6-bisphosphate aldolase ) is a 160 kDa, enzyme which catalyzes the conversion of fructose 1-6-biphosphate in glyceraldehyde 3-phosphate and dihydroxyacetone phosphate in the glycolytic metabolic pathway. There are also experimental data suggesting that nuclear ALD isoenzyme A might play an important role in cell proliferation. At the present time, the most useful serum markers of muscle injury following intense, prolonged exercise are: creatine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase myoglobin and troponin. Although serum ALD is not usually measured yet, it may be used together with CK to evaluate the status of muscle adaptation to training. Recent studies offered ALD a new perspective, as a future valuable biomarker in monitoring the evolution of muscle crush injuries, in order to prevent silent, but progressiv muscle fibers necrosis after injury. It has also been shown that ALD was an independent clinical prognostic marker in many other human cancers, being involved in some well-known signaling pathways.

Authors: Negreanu-Pirjol Bogdan-Stefan , Negreanu-Pirjol Ticuta , Sirbu Rodica , Popoviciu Dan Razvan
Published: January 2020

Aluminium toxicity is one of the major factors that limit plant growth and development in many acid soils, by multiple, and still poorly understood mechanisms. In this paper, the aluminium content determinations were done through atomic absorption spectrometry method, on seedlings of three culture plants, Helianthus annuus L. (sunflower), Sinapis alba L. (white mustard) and Triticum aestivum L. (wheat), grown in hydroponic conditions with different aluminium concentrations (50, 100 and 250 mg/kg) expose. AAS data were correlated with biometrical determinations (shoot length and dry biomass) and leaf pigments concentration assessment. Results emphasize that none of the selected species accumulates aluminium in aboveground organs such as shoots and leaves, indicating that root exclusion and/or sequestration are the strategies employed by all three species for limiting aluminium toxicity. In all three studied species, both average shoot length and dry biomass tended to be lower at higher aluminium concentration. Due to high variations among seedlings grown at the same aluminium concentration expose, these differences are not statistically significant. In sunflower seedlings, chlorophyll a and carotenoids had maximum values at the highest aluminium concentration (250 mg/kg), while chlorophyll b was more abundant at 100 mg/kg. In mustard, all pigments had their maximum concentrations at 100 mg/kg, while in wheat, an aluminium concentration increase progressively lead to a drop in pigments concentration.

The extrapyramidal symptoms (EPS) are commonly associated with antipsychotic treatment of schizophrenic patients. Accumulated evidence has shown that pathways of homocysteine and folate metabolism are linked to neurodegeneration and schizophrenia. The purpose of our study was to evaluate the homocysteine, vitamin B12 and folate serum levels in relation to drug-induced EPS in schizophrenic patients. The blood levels of homocysteine, vitamin B12 and folic acid were measured by chemiluminescent and electrochemoluminescence immunoassay methods in 34 patients diagnosed with schizophrenia (19 patients with severe EPS and 15 controls without EPS), recruited from Clinical Hospital of Neuropsychiatry Craiova, Romania. A significant association has been observed between EPS and vitamin B12 levels, the patients with severe EPS showed a reduced vitamin B12 levels (p=0.02). No correlation was observed between severe EPS and homocysteine or folate levels (p=0.2, respectively p=0.37). Our study suggests that deficiency of vitamin B12 blood levels is correlated with severe EPS in schizophrenic patients. Further studies included more patients and functional experiments are required to clarify the role of these biomarkers in relation with antipsychotic-induced EPS in schizophrenia.

Primary hyperparathyroidism is a common hormonal disorder, third in the order of importance after diabetes and hyperthyroidism. The aim of this study is to quantify qualitatively and quantitatively the effects of parathyroid hormone hypersecretion in a group of patients diagnosed with primary hyperparathyroidism. The study, was conducted on 200 patients with hyperparathyroidism, admitted in St. Spiridon Emergency Clinical Hospital in Iasi. In the study, we noted that primary hyperparathyroidism is three times more common in women than in males, being twice as many cases in patients older than 55 years as among the youngest. The most common forms are based on genetic determinism or are associated with other endocrinopathies. The obtained results encourage us to continue the research and, at the same time, we must point out that there is a high percentage of undiagnosed people among the apparently healthy population.

Published: January 2020

Our research is focused on improving the detection capabilities of single nucleotide polymorphisms (SNPs) with pathological significance within breast cancer 1, early onset gene (BRCA1). We employed the BRCA1 canonical probe sequence containing the common C allele and probes including the mismatches caused by C replacement with any of the other nucleotides (A, G or T). Two immobilization buffers with distinct pH and salt concentration were involved in the experimental and statistical analyses in order to assess the detection specificity and stability over time of the tethered probes in oligonucleotide microarrays. A high spreading of data points (standard deviation 0.16) was acquired from the fluorescent hybridization signal of the DNA probes diluted in Phosphate Buffered Saline (PBS), while the Disodium Phosphate (Na2HPO4) buffer was recommended by a standard deviation of 0.08 for further investigations. The high specificity of mismatch detection of DNA probes diluted in Na2HPO4 buffer was established by Student�s t test, revealing the statistical reliability of the DNA-printed slides after 1, 4, 8 and 21 days.

In the management of preeclampsia/eclampsia, it would be useful at least at European level, to have clear protocols for early detection and approach of cases with hypertension, as well as to create an algorithm to identify the predisposition to hypertensive pregnancy pathology. The aim has been to identify the favorable factors and the evolution of the pregnancy in the 100 patients admitted to the obstetrics clinic between January 2014 and December 2018, aged between 15-44 years, who have been diagnosed with preeclampsia. In recent years, the management of pregnant women with preeclampsia has improved a lot due to a better understanding of the pathogenesis and a refinement of adequate pregnancy monitoring. Obesity has been shown to be a risk factor in preeclampsia. Several studies have identified preeclampsia as an inflammatory condition. A large number of inflammatory markers, such as C-reactive protein (PCR) and Interleukin 6 (IL-6), have been shown to be elevated in pregnant women with preeclampsia.

Authors: Stanescu George , Badanoiu Alina , Nicoara Adrian , Voicu Georgeta
Published: January 2020

Autoclaved aerated concrete (AAC) is a light building material with high porosity, used to improve thermal and sound insulation of the buildings. AAC have a much better thermal efficiency than traditional masonry materials (bricks) or reinforced concrete elements; its use reduces the energy consumption (up to 7%) and consequently the carbon footprint of construction sector. The main constituents of autoclaved aerated concretes are portland cement, siliceous material (aggregate), water and different types of admixtures and additives (lime, foaming agent etc.). The aim of the research presented in this paper is to reduce the environmental impact of the technological process of ACC manufacturing; in this respect, one of the main components of AAC i.e. sand (natural raw material) was substituted with two types of inorganic waste i.e. glass (cullet) and waste brick; the sand substitution rate was comprised between 12.5-100% wt. The results indicate that both glass and brick waste can be incorporated into the autoclaved aerated concrete (AAC) structure without major modifications of apparent density (maximum 10% increase in correlation with substitution amount). For similar values of the apparent density, the AACs prepared with glass waste have higher values of compressive strength and thermal conductivity as compared with AAC with brick waste.

Polyvinyl alcohol is a biocompatible polymer used very commonly both in pharmaceutical and medical fields. Being a water-soluble polymer, it is suitable for the manufacture of hydrogels as well as cryogels used for various medical applications. The present work describes the preparation, structural and physico-mechanical characterization of polyvinyl alcohol cryogels loaded with ketoprofen. By cryogenic technique the polymeric solutions are transformed under certain conditions into porous, elastic and very compressible structures. They are able to absorb a large amount of liquids that they give off by gentle compression. The prepared cryogels were evaluated for different physical, chemical and structural properties, as following: internal morphology, equilibrium swelling ratio and mechanical testing. The cryogel structures show good elasticity and optimal swelling at different temperatures. Due to these properties the studied cryogels are suitable for use in various medical applications involving liquid absorption, mechanical resistance and anti-inflammatory effect.

Combustion inside diesel engine cylinders is the critical factor that controls the emission and combustion gases. Fuel injection in the engine cylinder is the decisive factor in the combustion of diesel engines and, consequently, combustion can be effectively controlled if the fuel injection process is efficiently controlled. From this perspective, the simulation of the complex processes of fuel injection in diesel engines in various situations can make a positive contribution to the optimization of marine propulsion systems. Also, correct dimensioning of the injection system components and its optimization and, implicitly, the combustion parameters, can have positive results in the context of reducing the impact of combustion gases of internal combustion engines, on the greenhouse effect and global warming.

Published: January 2020

Furosemide is a drug that has not only a renal effect, but also a vascular one, resulting in decreased left atrial and ventricularfilling pressure accompanied by an increase in venous compliance, all of this with significant effects on central cardiac hemodynamics.In dialysis patients, it is still unclear the efficiency of furosemide, a diuretic drug that inhibits the Na+, K+, 2CL� cotransporter in the renal tubular system. Also, furosemide need to be used at much higher doses because of its pharmacokinetic changes in the context of impaired renal clearance.The aim of our study was to investigate whether furosemide induces changes in cardiovascular hemodynamics in end-stage renal disease (ESRD) patients, using standard echocardiography and Tissue Doppler Imaging (TDI).We foundcorrelations between furosemide useand improved cardiac parameters, assessed by multiple echocardiographic variables, and we consider that furosemide has complementary effects in dialysis patients with residual diuresis.

The Intrauterine Device (IUD) is a modern method of intrauterine contraception, with high efficiency and long lasting uninterrupted use. The study of IUD dropout rate in first year of use and the frequency of unexpected pregnancies A prospective study was conducted within the Buna Vestire Galati Obstetrics and Gynecology Hospital during 2014 - 2015, which tracked women who had requested the installation of an IUD via the Family Planning Practice in the hospital ambulatory and who observed the recommended control visits. Various types of IUDs, most of them T-Cooper 380 and with progestagen (LNG-IUD), less with Gold were fitted. Of the total number of IDUs in that period, 67.6% returned to the indicated annual check or when some issues were reported. As a complaint to the method, there was only one case of intrauterine pregnancy and two IUDs lost. Three women gave up the IUD to have a pregnancy, and two requested extraction of an LNG-IUD due to repeated bleeding. One case had a PID that required admission and removal of IUD.

Regarding the rate of chromosomal abnormalities in spontaneous abortions, the data varies between 50 and 80% for first trimester miscarriages but there are several factors that may influence the rate of chromosomal aberrations as the selection bias of the cases for which cytogenetic analysis is done, the gestational age distribution, the maternal age distribution, the tissue samples analyzed, the expertise in cytogenetic methods. The aim of the research is to establish the incidence of chromosomal aberration in our study lot for the patients from the Western part of Romania, as there are no studies available for this specific population. In the present study, patients were included with pregnancy loss between 4 to 14 weeks of gestation for whom cytogenetic evaluation of the fetus was done in the University of Medicine and Pharmacy Timisoara. Of all results, 48.57% (34 out of 70) aborted fetuses had an abnormal karyotype. The gestational age of the aborted fetuses varied between 5 and 14 weeks of gestation, with a mean of 8.95 weeks of gestation. A higher incidence of chromosomal anomalies was observed in the group including patients � 35 years as compared with the group patients aged under 35 years old (55.5% vs 45.5%). The results of cytogenetic analysis of first trimester miscarriage is an important tool that can enhance diagnostic evaluation, and represent a critical information for counselling infertile couples. Post-miscarriage genetic and psychological counselling and appropriate treatment are crucial for the prevention of high psychological distress, psychiatric symptoms and psychopathology in these patients.

The aim of this study is to highlight the importance of percutaneous nephrolithotomy (PCNL) in the treatment of kidney stones with different chemical composition. We included in this study 200 patients with kidney stones who underwent PCNL. In most of the cases the stones were composed by calcium, usually calcium oxalate followed by struvite and uric acid component. The stones were mostly localized in the renal pelvis (142), inferior calyx (46) and ureteropelvic junction (4) and 28 cases with staghorn stones. Intraoperative complications were: migrating fragments (22%), hemorrhage (12%), lesions of the renal pelvis and difficulties of percutaneous access or dilatation (6%). The postoperative complications were: bleeding (20%), obstruction caused by stone fragments (22.5%), hydronephrosis (18%), fistula (13%). The average length of hospitalization after PCNL was 5.58 +/- 2.69 days SD. Stone-free rate was: 77.5%. PCNL is a safe and effective method of treatment for large and complex stones. Intra and postoperative complications after PCNL are not influenced directly by the chemical composition of the stones. It is important to evaluate the chemical composition of the stones in order to establish the treatment management and to recommend a proper conservative treatment in order to prevent the recurrence of the disease.

Because of its histological and embryological complex development, the ovary can be the source of a large variety of tumors, ovarian cancer being the fifth female neoplasia as a frequency. A major clinical significance is that the ovarian tumor is asymptomatic for a long period of time.Ovarian proliferative pathology raises a number of important issues from both theoretical and practical point of view. The change in the therapeutic attitude, especially in the areas of surgery and chemotherapy, has led in the last decades to an improvement in the survival rate. Our retrospective study included the analysis of 64 patients with ovarian cancer. Ovarian neoplasms should have a multidisciplinary approache with individualized treatment for each patient. The long-term survival remains, however, the detection of the tumor at an early stage, the undetectment in the initial stages leading to a survival rate of 5 years less than 20%.

The serum level of uric acid (UA) appears to be associated with a variety of cardiometabolic risk factors; however, direct association with the metabolic syndrome (MetS) remains controversial. The aim of this study is to investigate the association between serum levels of UA and the components that define MetS, differentiated by gender. 262 patients were enrolled (132 women and 130 men); mean value of the age: 58.7�16 year. Hyperuricemia was considered when the level of serum UA �7mg/dL in men, and � 6mg/dL in women; MetS was defined according to the IDF criteria. The prevalence of MetS in the studied group was 35.11% and the prevalence of hyperuricemia was 16.79%. Men with hyperuricemia had the highest prevalence of abdominal obesity (87.5% vs. 66.32%, p [0.001) and hypertriglyceridemia (65.62% vs. 45.91%, p [ 0.001) versus men with normal level of serum UA. Women with hyperuricemia also had a significantly higher incidence of abdominal obesity (75% vs. 57.51%, p [0.001), hypertriglyceridemia (58.33% vs. 38.33%, p [0.001), decreased HDL (50% vs. 33.33%, p [0.001) and hyperglycemia (66.66% versus 50%, p [0.001) compared to those with normal levels of serum UA. The majority of men with hyperuricemia have more than 4 of the MetS components. Hyperuricemia had a higher prevalence in patients with MetS, it may be considered as a causal factor of MetS. Elevated levels of serum uric acid were significantly more associated with the increasing number of MetS components. Early detection and treatment of hyperuricemia is essential for preventing the metabolic syndrome and its complications.

Steiger N-acylation of a-alanine with 4-(4-bromophenylsulfonyl)benzoyl chloride led to 2-[4-(4-bromophenylsulfonyl)benzamido]propanoic acid. This compound underwent intramolecular cyclization in the presence of N-methylmorpholine and ethyl chloroformate or acetic anhydride to the corresponding saturated azlactone. Then acylaminoacylation of dry aromatic hydrocarbons with 2-[4-(4-bromophenylsulfonyl)phenyl]-4-methyloxazol-5(4H)-one or 2-[4-(4-bromophenylsulfonyl) benzamido ]propanoyl chloride in the presence of anhydrous aluminum chloride led to corresponding a-acylamino ketones. These new intermediates were heterocyclized under the action of phosphorus oxychloride or concentrated sulfuric acid in the presence of acetic anhydride to the corresponding oxazoles. The newly synthesized compounds were characterized by spectral studies (FT-IR, UV-Vis, MS, 1H- and 13C-NMR) and elemental analysis. The purity of the new compounds was evaluated by RP-HPLC. The experimental research regarding to the in vitro cytotoxic activity of the new compounds were performed using Daphnia magna bioassay.

Nicotine and its main metabolite cotinine have been suggested to have psychoactive properties in humans and animals. The present study aims to investigate comparatively the psychoactive profile, as antidepressant and anxiolytic effects, of cotinine and nicotine in NMRI mice. The animalswere orally treated with nicotine (0.5mg/kg) and cotinine (5 mg/kg) for 14 days. Pharmacological tests (forced swimming test (FST) and tail suspension test (TST) for the antidepressant activity, as well as elevated maze test for the anxiolytic activity) were performed after 1, 7 and 14 days. Imipramine (25 mg/kg) was used as a control for the antidepressant activity. Imipramine and cotinine bothexerted comparable and statistically significant antidepressant effectsafter 7 days of treatment, while no effect was observedin the animals treated with nicotine. An important anxiogenic effect was revealed for imipramine after 14 days treatment. Nicotine was shown to have an axiolytic effect after 14 days treatment. The study highlighted some psychotropic effects of nicotine and cotinine in mice, depending on the treatment regimen.
