Die im Jahr 2020 in Deutschland praktizierte Siedlungs- und Wohnungspolitik erhält in Anbetracht ihrer Auswirkungen auf die soziale und ökologische Lage einen bitteren Beigeschmack. Arm und Reich driften weiter auseinander und einer zielgerichteten ökologischen Transformation der Art und Weise, wie Stadtentwicklung und Wohnungspolitik gestaltet werden, stehen noch immer historisch und systemisch bedingte Pfadabhängigkeiten im Weg. Diese werden nur durch eine integrierte Betrachtung sozialer und ökonomischer Aspekte sichtbar und deuten auf eine der ursprünglichen Fragen linker Gesellschaftsforschung hin: Die Auseinandersetzung mit dem Verhältnis von Eigentum und Gerechtigkeit.
Im Ergebnis stehen drei wesentliche Befunde: Der Diskurs zum Schutz des Klimas und der Biodiversität berührt direkt die Parameter Dichte, Nutzungsmischung und Flächeninanspruchnahme; zweitens steigt letztere relativ zu erhöhtem, individuell verfügbarem Kapital und insbesondere im selbstgenutzten Eigentum gegenüber Mietwohnungen; und drittens wächst der Eigentumsanteil mit fortschreitender Finanzialisierung des Wohnungsmarktes, sodass das Risiko sozialer und ökologischer Krisen sich verschärft.
Sintesis Graphene Melalui Iradiasi Microwave Sebagai Sensor Metanol
Authors: Rahayu Endah Fitriani , Amalia Alfi Nurul 
Published: April 2020

Graphene merupakan material 2 dimensional yang mempunyai sifat unik salah satunya memiliki luas permukaan sangat tinggi (~2630 m2g-1) yang dapat mengadsorbsi gas target. Tidak seperti sensor gas lainnya, sensor graphene dapat dioperasikan di bawah kondisi sekitar dan pada suhu kamar. Interaksi antar gas metanol dengan graphene menghasilkan perubahan pada sifak konduktifitas dan resistensinya yang membuat graphene menjadi elemen sensor yang baik. Struktur dan sifat elektronik graphene tergantung pada proses sintesisnya. Metode Hummers dan microwave irradiation dipilih karena biaya produksi efektif, menghasilkan graphene dengan sensitifitas tinggi terhadap target gas. Dari ketiga variasi pembuatan graphene dari Graphene Oxide (GO) melalui microwave irradiation yaitu 0,1 g-450 Watt, 0,1 g-630 Watt dan 0,02 g-450 Watt menunjukkan sensitifitas paling tinggi pada variasi graphene 0,02 g-450 Watt. Hal ini mengindikasikan semakin kecil massa GO dan semakin tinggi daya microwave membentuk sifat graphene yang lebih optimal terlebih untuk sensor gas.

Published: April 2020

Este artigo apresenta o resultado da investigação realizada no Curso de Qualificação em Auxiliar Administrativo, Proeja, Câmpus Iporá, do Instituto Federal de Educação, Ciência e Tecnologia Goiano. A pesquisa teve como foco investigar se a evasão ocorrida no referido curso estava relacionada, dentre outros fatores, com o ensino de Matemática. A metodologia aplicada foi de natureza qualitativa. O tipo de pesquisa foi o estudo de caso, quanto aos objetivos, exploratória. Realizou-se a coleta de dados por meio de aplicação de questionários semiestruturados e entrevistas com gravação em áudio. Observou-se nas respostas que a evasão escolar, além das questões de ordem socioeconômicas, tem-se as dificuldades no processo ensino-aprendizagem. Os dados indicaram fatores intra e extraescolares que contribuem na decisão de evasão escolar. A disciplina de Matemática, que é o foco dessa análise, não se confirmou como um fator relevante na decisão do aluno em evadir-se do curso. Identificou-se dificuldades no processo ensino-aprendizagem e falta de formação pedagógica específica para os professores da EJA. Acredita-se que esta pesquisa tem relevância social por abordar a questão da evasão como sendo um termômetro que indica a necessidade de ação política e escolar, para que o sujeito da EJA se aproprie de uma educação emancipadora.

Published: April 2020

Non-severe hypothyroidism has no strong association with hyponatremia. However, thyroid function tests (TFT) continue to be ordered as a first-line investigation. The objective of this study was to establish the prevalence of inpatient hyponatremia and to reiterate the association between thyroid disorders and hyponatremia based on study findings and current literature. A cross-sectional study on 3,478 in-patients adults of both gender admitted to a Malaysian tertiary hospital was carried out. Age, gender, sodium levels, thyroid stimulating hormone (TSH), free thyroxine (fT4) and clinical notes between 1/11/17-31/12/17 were extracted from the hospital’s information system. Bivariate analysis was performed using Mann-Whitney U, Chi-square and Spearman correlation tests. 21.9% of inpatients had hyponatremia of which 52% were mild. 359 (69%) of hyponatremic patients had a TFT sent where 71.9% were euthyroid. Sodium level is significantly correlated with age (R=-0.257, P<0.001). No correlations were found between sodium and TSH and fT4. Sodium was significantly lower in the non-thyroidal illness (NTI) group compared to the hypothyroid group. No significant differences in sodium were found between the hypothyroid group and other thyroid states. Hence it was conclude that in hyponatremia, TFT is indicated when there is clinical evidence of severe hypothyroidism, suspicion of hypothalamus-pituitary-axis disorder or when no cause of SIADH is apparent. Otherwise, TFT is unnecessary and costly as a first-line investigation.

Betel quid chewing is a detrimental recreational habit amongst Asians and a risk factor for oral cancer. Arecoline, a component of areca nut (a major constituent of betel quid) is a known carcinogen. However, the effect of areca nut crude extract is not much studied. To evaluate the cytotoxicity and morphologic effects of areca nut aqueous extract on mouse fibroblast cell line (L929). Dried raw areca nut obtained from a local market in Kota Bharu, Kelantan was prepared and suspended in DMEM (Dulbecco’s Modified Eagle’s medium), prior to serial dilution of 1.56, 0.781, 0.39, 0.195, 0.0976, 0.0488, and 0.0244 mg/ml. The L929 was then exposed to each of the aqueous areca nut extract dilutions and incubated at 37 °C for 24, 48 and 72 hours. Following incubation, the cytotoxicity level of treated L929 was measured using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium] assay. Five highest concentrations of areca nut extract showed significantly decreased L929 cell viability (1.56, 0.781, 0.39, 0.195, 0.0976 mg/ml) for all incubation periods compared to untreated cells (p<0.05). The IC50 values of aqueous areca nut extract on L929 were 0.1516, 0.1040, and 0.09136 mg/ml at 24, 48 and 72 hours, respectively. The L929 cell showed altered morphology when cultured in the extract for 24 hours. Higher concentrations of the areca nut aqueous extract is cytotoxic to L929. Prolonged exposure to the extract reduced the IC50 value. Investigation on the role of areca nut in cell proliferation could be further undertaken to assess its association with oral cancer.

Christia vespertilionis (L.F) Bakh. F. (red butterfly wing) is commonly used as a herbal medicine to treat symptoms of many diseases. The present study aimed to determine the in vitro antimalarial and cytotoxic activities as well as investigate the chemical compositions of the methanolic extract of C. vespertilionis leaves (CVME). The antimalarial activity of CVME against a chloroquine-sensitive (3D7) strain of Plasmodium falciparum was assessed by using a malarial SYBR Green I fluorescence-based (MSF) assay. The cytotoxic effect of CVME on cancerous (MDA-MB-231 and MCF-7) and noncancerous (NIH/3T3) cell lines were evaluated by using methyl tetrazolium (MTT) assay. Chemical constituents of CVME were analysed by using a gas chromatography/mass spectrometry (GCMS). CVME exhibited a moderate antimalarial activity with an IC50 value of 43.87 ± 2.04 µg/mL. CVME is considered as weak cytotoxic and significantly inhibited proliferation of MDA-MB-231 cells with an IC50 value of 37.45 ± 1.05 µg/mL (p<0.05) as compared to standard MCF-7 (IC50>100 μg/mL) and NIH/3T3 cells (IC50>100 μg/mL). This effect is selectively cytotoxic towards certain cancerous cells only. GCMS analysis suggests that CVME potentially contains several pharmacologically bioactive compounds such as tetrahydro-2-methyl- thiophene (61.77%), phytol (8.59%), 10-undecenoic acid (5.00%), 6-methyl heptyl-2-propanoate (4.96%) and 2-(2-benzothiazolylthio)-1-(3,5-dimethylpyrazolyl)-ethanone (2.70%) that might possess antimalarial and cytotoxic activities. It implies that CVME has selective cytotoxic activity against the breast cancer cell line (MDA-MB-231) and possesses an antimalarial activity against the 3D7 malaria parasite, suggesting the presence of bioactive compounds in C. vespertilionis leaves that could be a potential source of phytochemicals with high medicinal value to be used in cancer and malaria treatment.

The treatments are common carp (Cyprinus carpio), nilem carp (Osteochilus hasselti) and nilem carp (O. hasselti) padjadjaran strain that intraperitoneally challenged by A. hydrophila with 108 cfu ml-1. Parameters observed are mortality hours, gross pathological symptoms and haematological profile for 24 hour. Nilem padjadjaran strain mortality reached 100% after 10th hour postchallenge, while common carp and nilem reached 100% mortality in 14th hour postchallenge. Gross pathological symptoms showed reddish lesions, abdominal dropsy and exopthalmia, with first sign of reddish lesions is appeared in nilem padjadjaran strain at 3rd hour postchallenge. Feed responses of all fish are lost in 7th hour postchallenge. Nilem padjadjaran strain has no shock responses in 9th hour postchallenge. Total erythrocyte counts of common carp, nilem and nilem padjadjaran strain before challenged are 2,15 x 106, 2,45 x 106 dan 2,14 x 106 cells mm3-1, after 10th hour postchallenge becomes 1,2 x 106, 1,69 x 106 dan 1,21 x 106 cells mm3 -1. Total leukocyte count of common carp, nilem and nilem padjadjaran strain before challenged are 6,48 x 104, 7,36 x 104 and 6,56 x 104 cells mm3-1, and tend to increase in 3rd and 7th hour postchallenge (8,8 x 104, 9,12 x 104 dan 105 cells mm3-1 and 1,26 x 105, 1,3 x 105, 1,27 x 105 cells mm3-1), but in 10th hour postchallenge the total leukocyte count becomes decreased again (1,24 x 105, 1,26 x 105, 1,18 x 105 cells mm3 -1). Thus, nilem carp padjadjaran strain has no better immune performance than its parents.

In the current study, a total of 86 soccer’s players with mean age of 14 years drawn from Terengganu soccer academy were tested in performing 10 parameters aiming at determining the performance of those players based on assessing the contribution of each activity and its corresponding significant level. The 10 performance related parameters involved anthropometry (BMI), fitness test (agility, coordination, muscular endurance (push and sit up), power, YoYo level), and football skill test (dribbling with ball, dribbling without ball and juggling). All the parameters testing is carried out based on international standard and performed by well-trained staff. The Pearson correlation analysis was used to achieve the objective in this study. Result shows a positive correlation between the two types of muscular parameters; the power is influenced by BMI and coordination; the specific football tests are highly impacted by the power and agility. The coefficient of determination and the significance level -values show that the parameters that can be significantly considered are the anthropometric BMI (0.020), agility (0.025), muscular endurance (0.039 and 0.043), power (0.039), special football test without the ball (0.041), and juggling (0.046). The coordination, YoYo, football special test with the ball were not found to be significantly accounted for preparing the young players to achieve the required performance. Based on the results of the coefficient of determination and the significance -values of the parameters, a model was proposed to determine the highest and lowest parameters that play important roles in the selection of young players.
