Considering the significant role of alpha tocopherol (α-Toc) under different environmental cues, experiments were conducted on mungbean plants under varying water regimes. First experiment was planted in plastic pots in order to check the influence of foliage spray of α-Tocopherol in terms of growth, gas exchange and different physio-biochemical characteristics in mungbean plants under water deficit stress. After three weeks of seed germination, both mungbean cultivars (Cyclone 7008 and Cyclone 8009) were subjected to drought treatment (60% and 100% field capacity). The 0, 100, 200 and 300 mg L-1 were the alpha tocopherol levels treated as foliage spray after 30 days of water stress treatment. Water deficit conditions retard morphological parameters, photosynthetic pigments such as chlorophyll a and b levels, relative water contents (RWC), gas exchange characteristics and total soluble proteins (TSP), yield per plant, while an increase was observed in the relative membrane permeability (RMP), glycinebetaine (GB), proline, sugars, H2O2, AsA, phenolics, MDA, TFAA and the actions of antioxidants in both mungbean lines. Foliarly appliedα-Toc significantly improved plant growth, plant height, chlorophyll b, RWC, GB, non-reducing sugars, E, gs, Ci, Ci/Ca, AsA, TSP, TFAA and catalytic actions of peroxides and catalase enzymes. The inconsistent behavior was depicted by both mungbean cultivars to externally used tocopherol and drought stress to relative water contents and different gas exchange characteristics. The cv. Cyclone 7008 was significantly showed improved reducing, non-reducing sugars, Hydrogen peroxide and total soluble protein while cv. Cyclone 8009 in leaf proline and total phenolics. Overall, externally applied Toc particularly 300 mg L-1 was effective in developing plant growth of both mungbean cultivars. In case of green pods different biochemical analyses, as a whole, the external application of 200 and 300 mg L-1 of α-Toc significantly increased the chlorophyll a & b, proline and total phenolics concentrations and actions of SOD, POD and CAT enzymes in used mungbean varieties. In field experiment, under normal and withheld irrigations, the exogenous treatment of α-Toc effectively increased growth parameters, chlorophylls, total soluble phenolics, free proline, glycine betaine, TSG, sugars, TSP, TFAA, antioxidants and invivo Toc and harvest attributes but significantly decreased MDA and H2O2 levels. In short, of various used different concentrations of α-Toc levels, last two concentrations were better convenient for both mungbean cultivars under applied field conditions.

دھی دی خوشی

دھی دی خوشی

پرانے زمانے دی گل اے کہ کسے ملک اتے اک بہت رحم دل بادشاہ حکومت کردا سی۔ اپنی رعایا دا خیال رکھدا تے اوہناں نوں ودھ توں ودھ سہولتاں دیون دی کوشش کردا۔ پر ربّ دا کرنا انج ہویا کہ ویاہ دے ویہہ سال بعد وی اوس گھر کوئی اولاد نہ ہوئی۔ ایس کر کے اوہ بہت پریشان رہندا سی۔ اوس کئی حکیماں توں اپنا تے ملکہ دا علاج وی کروایا ربّ نے اوس نوں اولاد دی نعمت عطا نہ کیتی۔

اک دن اوہ اکلا اپنے محل دے بوہے تے کھڑا بالاں نوں کھیڈ دا ویکھ رہیا سی۔ اوہدیاں اکھاں وچ اولاد نہ ہوون پاروں اتھرو آ گئے۔ اچانک بادشاہ نوں کھڑا ویکھ کے اک فقیر اوہدے کول آ گیا تے افسردہ ہوون دی وجہ پچھی۔ بادشاہ نے دسیا کہ بابا میرے کول اولاد نئیں اے۔ بابے نے آکھیا میں کئی دناں دا بھکھا آں۔ توں مینوں روٹی کھلا دے۔ ربّ تینوں اولاد دیوے گا۔ بادشاہ اوس فقیر نوں بڑے ادب نال لے کے محل اندر آیا تے شاہی برتناں وچ اوس نوں کھانا پیش کیتا۔ جان لگیا بادشاہ نے نذرانے دے طور تے کجھ پیسے دے دتے۔ فقیر اولاد دی دُعا دیندے ہوئے چلا گیا۔

ربّ نے فقیر دی دُعا قبول کر لئی تے اک سال بعد ربّ نے بادشاہ نوں اک سوہنی دھی دا تحفہ دتا۔ اوہ تے ملکہ دھی دی آمد تے بہت خوش سن۔ جدوں رعایا نوں شہزادی دا پتہ لگا تاں اوہ وی بہت خوش ہوئی۔ بادشاہ نے سارے ملک وچ خیرات ونڈی۔ ایس توں غریباں نوں کھانا کھاون دا وی انتظام کیتا۔ خود اک وڈی دعوت دا انتظام اپنے شہر وچ کیتا۔ مقررہ تاریخ تے بہت سارے لوک ایس دعوت وچ آئے اوہناں شہزادی نال کپڑے، کھڈو نے تے...

The Third Party Involvement in Resolving River Water Disputes between Pakistan and India

Water and related issues are gaining importance in the present world politics. It is believed that water would be the source of some major future conflicts in many regions including South Asia. Water distribution between Pakistan and India has become a serious political issue since independence. The problem has its roots in the partition of the Indian Subcontinent in 1947. Although the issue was resolved amicably by the two states in 1960 and a treaty was signed, even then number of other issues developed after the treaty. One of the important aspects of the settlement route was the Indian refusal and Pakistan’s insistence on the presence and participation of any third neutral party. Despite the Indian policy of bilateralism on many regional issues, water disputes and resolution remained a classical example of multilateralism, where at least on four major occasions the settlements were reached with the involvement of a third neutral party.

Leadership and Community Mobilization for Education Access to Marginalized Communities: the Case of an Ngo in Sindh, Pakistan

Education can uplift individuals, families and nations from poverty and enable their socio-economic mobility, and for that reason, achieving universal access to education has been included in several international and national memorandums. The United Nations, in 1948, declared education a basic human right. World’s leaders came together in Dakar (2000), then in New York (2015) and set the global ‎agenda for ensuring equitable education access for all. Generally, it is state’s responsibility to ensure education provision but sadly, the current education situation in Pakistan shows the bleak picture of government’s interventions and successes in the sector. For decades, Pakistan has faced serious challenges and setbacks to fulfill its promises on the above commitments, as around 22.6 million children are out of schools today. Non-government organizations (NGOs) have emerged as alternatives to help the government and communities to catch up and fulfill the local-global promises. Like the government, NGOs have also been contested in the literature between being solution and problem to providing affordable, relevant, quality and sustainable education to the marginalized communities. Against these local-global realities and theorizations, this qualitative case study explored how a local educational NGO, through its leaders’ thoughts and actions mobilized underprivileged communities to increase their children’s access to quality education. The study’s findings are consistent in describing NGO’s and its schools’ positive role in making education accessible. It is found that providing education access in the economically deprived, religiously fragile and politically charged conditions of rural Sindh demand more complex, creative and yet contextualized approaches. The NGO (AAS, pseudonym) and its schools considerably expanded access of quality education to the public through the clear policy-practice match in maintaining standard education, social mobilization, inclusiveness, subsidized-fee and social capacity-building projects. Apart from these, (a) the schools’ proximity, (b) excellent infrastructural facilities, (c) safe learning environment, (d) educational opportunities and (e) committed local female teachers, -- all improved access, quality, sustainability, relevance and community’s emotional engagement and advocacy of the schools. An important finding was the establishment of schools’ direct relationships with communities and individuals instead of using specially designed structures like school management committees. Community mobilization took place and sustained due to highly committed and culturally informed NGO’s and schools’ leadership. They aligned their organizational mission and policies with the contextual nuances. As a result, schools’ interventions were not seen a threat to local traditions and norms. AAS’s schools accomplishments to reach out poor families ultimately depended
