Abstrak Fenomena pacaran adalah hal yang wajar bagi mahasiswa, di mana ada dua lawan jenis menghabiskan waktu bersama. Dalam prefektif psikologi pacaran sendiri dapat menimbulkan konsentrasi yang baik dan juga dapat menimbulkan konsentrasi yang buruk, bukan hanya konsentrasi yang akan terpengaruh, Kesehatan fisik, gangguan mental, dll juga akan terpengaruh. Tergantung hubungan pasangan yang di jalani. Namun pacaran ini termasuk hal yang diharamkan dalam Islam. Pada jurnal ini hal yang akan dibahas yaitu mengenai pengaruh pacaran terhadap konsentrasi mahasiswa di PENS. Metode penelitian yang digunakan dalam jurnal ini yaitu berupa metode kualitatif. Data didapatkan dengan menanyakan pendapat kepada partisipan tentang pengaruh pacaran terhadap prestasi belajar mereka. Hasil penelitian yang telah dilakukan menunjukkan bahwa pacaran memang memiliki pengaruh terhadap konsentrasi belajar mahasiswa. Mengganggu konsentrasi belajar, menurunkan prestasi kuliah, dapat memengaruhi hubungan seseorang baik dengan teman maupun keluarga, juga menyebabkan lupa hal-hal karena memikirkan pacar. Berbagai metode ada di dalam islam maupun di luar untuk meningkatkan konsentrasi belajar. Bisa dengan melakukan olahraga dan meditasi secara rutin, berdoa ketika ingin belajar, dan juga berwudhu sebelum melakukan sebuah kegiatan.   Abstract The phenomenon of dating is a natural thing for students, where there are two opposite sexes spending time together. In prefective psychology, dating itself can cause good concentration and can also cause poor concentration, not only concentration will be affected, physical health, mental disorders, etc. will also be affected. It depends on the couple's relationship. However, this courtship is forbidden in Islam. In this journal, what will be discussed is the influence of courtship on the concentration of students in EEPIS. The research method used in this journal is a qualitative method. The data was obtained by asking participants' opinions about the effect of courtship on their learning achievement. The results of the research that have been carried out show that dating does have an influence on the concentration of student learning. Disrupts learning concentration, lowers college achievement, can affect one's relationships with friends and family, also causes forgetting things because of thinking about a boyfriend. Various methods exist within Islam as well as outside to increase the concentration of learning. You can do sports and meditation regularly, pray when you want to study, and also perform ablution before doing an activity.

Milk thistle's extract by an organic solvent is known as silymarin, which is a mixture of about 75% flavolignan and trace content of flavonoid (mainly taxifolin), other ingredients involve fatty acids and polyphenolic compounds. The major flavolignans are silybin, isosilybin, silydianin, and silychristin, quantitatively silybin is considered as the major compound followed by isosilybin, and both are represent approximately 60% of silymarin. This study was designed to determine the concentration of silybin in different parts of the plant and to study the effect of extraction methods, solvents and the time of collection on silybin concentration, which have been done by HPLC instrument. The results show that the higher yield of silybin is obtained from the seed using ethanol in the soxhlet apparatus and that all other parts of the plant which are produced in huge amount by the plant also contain a good concentration of silybin when compared with seeds, So they can be used as an alternative source for silybin production.

Abstract Background Anti-myeloperoxidase antibody (anti-MPO) is an important biomarker for anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAVs). However, the complicated operation procedures and insufficient sensitivity of conventional anti-MPO detection methods limit their application in monitoring efficacy of AAVs in clinical diagnosis. Herein, a dual amplified electrochemiluminescence (ECL) immunosensor based on multi-function PtCo nanozymes/CdS nanocrystals@graphene oxide (PtCo/CdS@GO) luminophores and K2S2O8/H2O2 coreactants has been fabricated for ultrasensitive detection of anti-MPO. Results PtCo/CdS@GO luminophores as novel signal amplification labels and nanocarriers to load rabbit anti-mouse IgG were synthesized by co-doping with Pt and Co nanozymes simultaneously with several considerable advantages, including astonishing peroxidase-like catalytic activity, high-efficiency luminescence performance and superior stability in aqueous solutions. Meanwhile, upon the K2S2O8/H2O2 coreactants system, benefiting from the efficient peroxidase-like activity of the PtCo/CdS@GO toward H2O2, massive of transient reactive intermediates could react with K2S2O8, thus obtaining higher ECL emission. Therefore, the developed ECL immunosensor for anti-MPO detection displayed good analytical performance with good concentration linearity in the range of 0.02 to 1000 pg/mL and low detection limit down to 7.39 fg/mL. Conclusions The introduction of multi-function PtCo/CdS@GO luminophores into the established ECL immunoassay not only was successfully applied for specific detection of anti-MPO in clinical serum samples, but also provided a completely new concept to design other high-performance luminophores. Meaningfully, the ECL immunoassay strategy held wide potential for biomarkers detection in clinical diagnosis. Graphic abstract

Carboxylate anions are analytical targets with environmental and biological relevance, whose detection is often challenging in aqueous solutions. We describe a method for discrimination and quantitation of carboxylates in water buffered to pH 7.4 based on their differential interaction with a supramolecular fluorescent sensor, self-assembled from readily available building blocks. A fifth-generation poly(amidoamine) dendrimer (PAMAM G5), bound to organic fluorophores (calcein or pyranine) through noncovalent interactions, forms a [dye•PAMAM] complex responsive to interaction with carboxylates. The observed changes in absorbance, and in fluorescence emission and anisotropy, were interpreted through linear discriminant analysis (LDA) and principal component analysis (PCA) to differentiate 10 structurally similar carboxylates with a limit of discrimination around 100 μM. The relationship between the analytes’ chemical structures and the system’s response was also elucidated. This insight allowed us to extend the system’s capabilities to the simultaneous identification of the nature and concentration of unknown analytes, with excellent structural identification results and good concentration recovery, an uncommon feat for a pattern-based sensing system.

To evaluate if the combined foliar application of nitrogen (N) and zinc (Zn) in broccoli improves the efficiency of the single Zn biofortification, five treatments were tested: (i) control; (ii) one Zn application at the beginning of flowering (0.5M1); (iii) combined 0.5M1 with N application (0.5M1N); (iv) two Zn applications, one at the beginning of the flowering and other after two weeks (0.25 + 0.25) and (v) combined 0.25 + 0.25 with N (0.25N + 0.25N). The Parthenon cultivar showed a good concentration of Ca, Fe, Mg, and Zn, with good bioavailability and glucosinolates, mainly in the florets, and high antioxidant activity and total phenols, mainly in the leaves, showing their potential not only as regards to human consumption, but also for the use of their by-products. All the studied treatments increased floret growth (19%), antioxidant capacity and total phenol content, not affecting Ca, Fe, and Mg concentrations. Glucosinolate content was mostly independent from the studied treatments, decreasing slightly in terms of glucoiberin and the Zn concentration in the florets increased in >50 mg Zn kg−1 in the split treatments and ~40 mg Zn kg−1 when the application was unique, with excellent bioavailability, measured as PA:Zn ratio. Therefore, 0.25 + 0.25 and 0.25N + 0.25N applications have been confirmed as the applications that improve more both growth and accumulation of Zn and biocompounds in broccoli.

AbstractWe consider the recovery of square-integrable signals from discrete, equidistant samples of their Gabor transform magnitude and show that, in general, signals can not be recovered from such samples. In particular, we show that for any lattice, one can construct functions in $$L^2({\mathbb {R}})$$ L 2 ( R ) which do not agree up to global phase but whose Gabor transform magnitudes sampled on the lattice agree. These functions have good concentration in both time and frequency and can be constructed to be real-valued for rectangular lattices.

Metals in the form of salts or as such have a profound effect on development and growth of crops. Various soil samples at different regions of Dehradun (India) have been analysed analytically for the concentration of various metal ions in relation to the growth and development of wheat, mustard and barley. The various metal ions have been found in a good concentration range at which the concerned crops could show maximum growth and development. The concentration of various salts like phosphate ion as determined spectrophotometrically was found to be in between 0.732 to 1.610, for NO3- the concentration was found in between 0.210 to 0.998 mg/kg, and the concentration of NO22- was found to be 0.138 to 0.475 mg/kg. The metal ions were determined analytically and the concentration of various metals like Pb2+ was found in the range of 0.101 - 0.265 mg/kg, Zn in the range of 0.047 – 0.175 mg/kg, Cu in the range of 0.015 – 0.101 mg/kg and the concentration of Fe was found in the range of 0.120 – 0.462 mg/kg. Na, K, Li and Ba were analysed by flame-photometry and the concentration of Na was found in the range 0.10- 0.47 ppm, K in the range of 0.70 – 2.4 ppm, Li 0.00 – 0.01 ppm and the Ba in the range of 0.00 – 0.03 ppm. Also the data reveals the distributions of heavy metals in the agricultural land of the concerned region and can be used to estimate the risks associated with the consumption of crops grown on such soils. So the soil samples which have been examined can be opted for the production of various crops as the soil samples show a good quality and quantity of various mineral ions. The Dehradun in total bears a good range of forests and soil is rich of various types of mineral salts so could be used for the growth of multiple crops.

The present study was conducted to assess the empowerment level of women in the fisheries sector in the Ganjam district of Odisha. In the inland sector, the highest numbers of women are of the fishermen population in Ganjam district i.e. 29476 out of a total 263514 number of female fisheries population of the state (Directorate of Fisheries, Government of Odisha, 2015). A very good concentration of women is involving in fisheries activities in this district. But when sector-specific cases are concerned, there are very few studies found where different dimensions of women empowerment through fisheries are discussed. The results revealed that the majority of the respondents (66.60%) in the Inland sector are grouped under a medium level of empowerment followed by low and high-level empowerment (16.70%). These results indicated that there is a significant move towards the empowerment of women in the case of inland fisheries. However, in the Marine sector equal percentage of respondents belonged to both medium and high levels of women empowerment i.e. each 30 (50.00%) and low level of empowerment was nil which indicates the level of empowerment in the marine fisheries activities compared to inland fisheries. With this background, the overall empowerment score was categorized into the low, medium, and high level of empowerment where a majority of the respondents (71.6%) were under the medium level of empowerment followed by the equal percentage of the low and high level of empowerment (14.2%). The composite score of empowerment of women is also encouraging. However, efforts are needed to bring women empowerment from medium level to a higher level. There is also a need to uplift a section of women who are still in the lower category of empowerment.
