Authors: JAMIR TEMSURENLA , T AJUNGLA 
Published: May 2020

Objectives: The objective of the study was to estimate the seasonal variations in the antioxidant capacities, total polyphenol content (TPC), total flavonoid content (TFC), and tannin content (TC) of tea leaf extracts from two different plantation sites.
Methods: Samples were collected from two tea gardens in Tuli and Ungma situated at N 26°39’19.3 E 094°39’22.7 and N 26°17’30.6 E 094°28’29.2, respectively, under the Mokokchung district of Nagaland, India. TPC, TFC, and TC from sample extracts were determined using Folin–Ciocalteu reagent, aluminum chloride colorimetric, and Folin–Ciocalteu assay. Apart from these, antioxidant capacities were analyzed using ferric reducing ability of plasma (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay.
Results: The concentrations of total polyphenol, flavonoid, and tannin varied from 552.029±8.079 to 305.647±1.744 mg gallic acid equivalent/g, 238.770±0.508–148.457±1.653 mg catechin equivalent/g, and 26.453±0.485–20.173±0.173 mg tannic acid equivalent/g, respectively. FRAP and DPPH assay displayed value ranging from 2.564±0.023 to 1.074±0.023 mmol Fe(II) equivalent/g and 3.612±0.053–2.076±0.028 mmol Trolox equivalent/g. Significant seasonal variations in concentrations of these compounds were observed and a positive correlation between antioxidant capacities and phenolics of tea leaf extracts was established.
Conclusion: Tea (Camellia sinensis (L.) O. Kuntze) has been regarded as a plant of immense medicinal and therapeutic value since time immemorial. The tea leaf extracts analyzed in this study gave high TPC, TFC, and TC, as well as high antioxidant activity in terms of DPPH and FRAP value. Studying such properties in tea leaves contributes more to our understandings of health benefit potentials in tea leaves and the quality of tea leaves on the basis of seasons and sites where they are planted.

Zooplanktonik
organizmalar pelajik besin ağının şekillenmesinde ve biyokimyasal döngülerin
gerçekleşmesinde anahtar rol oynamaktadır. Zooplankton biyokütlesi ve dağılımı
hakkında bilgi sahibi olmak, bu canlıların ekosistemdeki organik madde ve enerji akışına katkılarını
tahmin etmek için önem arzetmektedir. Bu bağlamda, 2008 yılının Nisan ve Ekim
aylarında Türk Boğazlar Sistemi’nde tek hat boyunca belirlenen istasyonlardan WP-2
plankton kepçesi (ağ göz açıklığı 200µm) ile zooplankton örnekleri toplanmıştır.
Bu örneklerden ölçülen biyokütle değerlerinin epipelajik bölgedeki alansal ve
dikey dağılımı belirlenerek bölgedeki bu konuyla ilgili bilgi eksikliği
giderilmeye çalışılmıştır.

TBS’de ortalama
mesozooplankton mevcut stoğu alansal ve dikey olarak farklılık göstermiştir. Mesozooplankton
biyokütlesi genel itibariyle ilkbaharda yüzey karışım tabakasında yoğunlaşmış,
derinlik ile birlikte azalmıştır. Sonbahar periyodunda ise geçiş tabakası
ortalama mesozooplankton biyokütle değerleri bakımından daha yüksek bulunmuştur.
Genel olarak boğazlarda yüksek olan bu değerler, Marmara Denizi’nin iç
bölgelerinde özellikle kuzey batısında oldukça düşmüştür. Bölgedeki biyokütle
dağılımında istasyon derinliği, derinlik tabakaları ve oksijenin miktarı etkili
olmakla birlikte, örnekleme periyodu boyunca gerçekleştiği bildirilen musilaj
olayının sıcaklık ve tuzluluk gibi önemli parametrelerin etkisini büyük ölçüde
maskelediği düşünülmektedir.
Para valorizar a dimensão da vida cotidiana: articulações ao debate das sustentabilidades
Authors: Martins Gabriel Dos Santos 
Published: May 2020

Propomos a valorização da dimensão do cotidiano enquanto enfoque de análise que exerce importância para o debate que constrói a necessidade de novos padrões de sustentabilidades frente às segregações socioambientais. A discussão ambiental comumemente está relacionada ao privilégio das grandes dimensões, dos grandes eventos (catástrofes) ambientais, relacionadas aos resultados sociais advindos dos mesmos. A supervalorização de tais processos são entendidos, aqui, enquanto produtores de alienações que negam e camuflamam processos de injustiças ambientais promovidas no dia-a-dia. Valorizar o cotidiano, nos embasamentos de Lefebvre e Heller, para a compreensão mais sólida da realidade, se faz de suma importância para entrelaçar redes e propostas de sustentabilidades que privilegiam o plano da vida comum, a autonomia territorial e a participação ativa dos sujeitos.

ABSTRACT Tamarind (Tamarindus indica) is a multipurpose tree that can be developed either vegetative or generative propagation. Vegetative propagation of tamarind can produce abundant fruit if the plant organs derived from superior parent trees. However, due to the rare availability of natural tamarind stands now days, then the generative propagation by seed, can be the right choice for its cultivation. Generally, tamarind seeds are dormant, so it requires a pre-treatment to break its dormancy. One way to break it was using potassium nitrate (KNO3). This study aimed to determined the response of soaking treatment to the germination of tamarinds seeds with KNO3 solution at various concentrations and the most effective concen-tration of KNO3 solution to stimulate tamarind seeds germination. The experiment was con-ducted at the Greenhouse Seed Control and Certification Institute of Food Crops and Horticulture (BPSBTPH) Lampung Province, from July to August 2013. This research used Completely Randomized Design (CRD), with 5 treatment of KNO3 solution soaking (0,1%, 0,2%, 0,3%, 0,4% and without KNO3) and 3 replications. Every unit of experiments con-sisted of 100 seeds. Observed parameters included percentage of germination, mean of day germination and percentage of germination seeds per day. Bartlett test was employed to figure out the homogenity of datas. Then, analysis of variance was used to analyse datas. Honestly Significant Difference (HSD) was used to the advanced analysis. The entire data tested on 5% significant level. The result showed that soaking of tamarind seeds in water (without KNO3) during 24 hours gave the best response to break its dormancy, and the most effective concentration to break dormancy of tamarind seeds was 0,4%.
