A gas-rich AGN near the centre of a galaxy cluster at z ~ 1.4

The formation of the first virialized structures in overdensities dates back to ~9 Gyr ago, i.e. in the redshift range z ~ 1.4 - 1.6. Some models of structure formation predict that the star formation activity in clusters was high at that epoch, implying large reservoirs of cold molecular gas. Aiming at finding a trace of this expected high molecular gas content in primeval clusters, we searched for the 12CO(2-1) line emission in the most luminous active galactic nucleus (AGN) of the cluster around the radio galaxy 7C 1756+6520 at z ~ 1.4, one of the farthest spectroscopic confirmed clusters. This AGN, called AGN.1317, is located in the neighbourhood of the central radio galaxy at a projected distance of ~780 kpc. The IRAM Plateau de Bure Interferometer was used to investigate the molecular gas quantity in AGN.1317, observing the 12CO(2-1) emission line. We detect CO emission in an AGN belonging to a galaxy cluster at z ~ 1.4. We measured a molecular gas mass of 1.1 x 10^10 Msun, comparable to that found in submillimeter galaxies. In optical images, AGN.1317 does not seem to be part of a galaxy interaction or merger.We also derived the nearly instantaneous star formation rate (SFR) from Halpha flux obtaining a SFR ~65 Msun/yr. This suggests that AGN.1317 is actively forming stars and will exhaust its reservoir of cold gas in ~0.2-1.0 Gyr.Comment: 5 pages, 3 figures, accepted for publication in Astronomy & Astrophysic

Evaluation of the sleep modulating effects of methanolic extracts of Strychnos spinosa and Strychnos innocua fruits in mice

This study aimed to evaluate the sleep modulating properties of Strychnos spinosa and Strychnos innocua fruits in Swiss albino mice. The depressant effect of the extracts on the central nervous system was studied using a diazepam-induced sleep model in mice. The mice were divided into four groups of six mice each. The test groups received Strychnos spinosa and Strychnos innocua fruits extracts at the doses of 250, 500, and 1000 mg/kg body weight intraperitoneally. In contrast, the control group received distilled water at 10 ml/kg. Diazepam (Ranbaxy®, India) was used as a standard drug and administered 30 minutes after the initial treatment. The lethal doses (LD50) of the two extracts were estimated to be >5000 mg/kg. The results obtained from the onset of sleep of rats administered methanol extracts of Strychnos spinosa, and Strychnos innocua fruits showed that the extracts at 250, 500, and 1000 mg/kg, respectively, did not significantly (p >0.05) alter the onset of sleep when compared with the control. The onset of sleep in the groups treated with Strychnos spinosa fruit extracts indicated a dose-dependent decrease pattern. The study also revealed a prolonged duration of sleep in all the experimental groups treated with the two extracts compared to the control group. The treated groups of 250, 500 and 1000 mg/kg significantly (p <0.05) prolonged the duration of diazepam-induced sleep in a dose-dependent manner when compared to the control group. The group treated with 1000 mg/kg of Strychnos innocua fruit extract was significant (p <0.05) compared to the control group. In conclusion, the high LD50 observed in this study suggests that the two extracts are relatively safe and contain promising bioactive ingredients that cause sleep modulation in mice

Hubungan Antara Citra Diri Dengan Intensi Membeli Produk Fashion Bermerek Tiruan Pada Mahasiswa Tahun Pertama Fakultas Ekonomika Dan Bisnis Universitas Diponegoro

Penelitian ini bertujuan mengkaji hubungan antara citra diri dengan intensi membeli produk fashion bermerek tiruan pada mahasiswa tahun pertama Fakultas Ekonomika dan Bisnis Universitas Diponegoro. Citra diri adalah penilaian seseorang terhadap segala hal yang berkaitan dengan dirinya meliputi penampilan (fisik), psikologi, sosial akan kondisinya saat ini atau pun kondisi yang dicita-citakan sebagai hasil pengalaman. Intensi membeli produk fashion tiruan bermerek adalah keinginan, niat seseorang untuk melakukan pembelian produk fashion (baju, tas, sepatu, aksesoris) bermerek tiruan (KW) tertentu dalam rangka untuk memenuhi kebutuhan dan keinginannya.Jumlah populasi penelitian 600 mahasiswa tahun pertama Fakultas Ekonomika dan Bisnis Universitas Diponegoro. Sampel penelitian yang digunakan ialah 221 mahasiswa. Teknik pengambilan sampel menggunakan teknik convenience sampling. Data dianalisis mengunakan uji statistik non parametrik yaitu uji korelasi Spearman rho. Berdasarkan hasil perhitungan statistik diperoleh koefisien korelasi Spearman rho (rs) sebesar -0,055 dengan nilai p= 0,413 (p > 0,05) yang berarti tidak ada hubungan antara citra diri dengan intensi membeli produk fashion bermerek tiruan pada mahasiswa tahun pertama Fakultas Ekonomika dan Bisnis Universitas Diponegoro

Assessing the Emotional Intelligence and Academic Performance of Quantity Surveying Students

Previous studies have established that Emotional Intelligence (EI) has an effect on the performance of students. EI of construction students has been found to be lower than their counterparts in other disciplines. These studies, however did not evaluate the EI in relation to performance. Thus this creates a gap with regards to the relationship of EI and the academic performance of construction students. Therefore, this study assessed the emotional intelligence and academic performance among quantity surveying students. Data were collected by means of closed–ended questionnaires, which were administered online. Data gathered were analysed using descriptive (Mean, Frequency and Standard Deviations) and inferential (Analysis of Variance) statistics through the use of Statistical Package for the Social Sciences (SPSS software). The 16-item Wong and Law Emotional Intelligence Scale was used to evaluate the level of emotional intelligence and explore the effect on academic performance. The results of the study indicated that quantity surveying students have a high level of EI, and a significant difference was found between students EI and academic performance. Students with higher Academic performance were found to have higher level of Self-Emotion Appraisal (SEA) and Use of Emotions (UOE). However, the results did not show a significant difference under Others’ Emotion Appraisal (OEA) and Regulation of Emotions (ROE). Thus this study concluded that EI of quantity surveying students gave an indication of the level of academic performance (CGPA) and therefore recommends that EI should be incorporated into academic curricula to improve the EI level of constructionstudents.&nbsp
