Impact of Climate, Climate Change and Modern Technology on Wheat Production in Nepal: A Case Study at Bhairahawa
Janak Lal Nayava,Rabi Singh,Madan Raj Bhatta
Journal of Hydrology and Meteorology , 2009, DOI: 10.3126/jhm.v6i1.5479
Abstract: The relation between climate and wheat production in Nepal was studied for the period 1970/71-2007/08. Due to the topographical differences within short north-south span of the country, Nepal has wide variety of climatic condition. About 70 to 90% of the rainfall occurs during the summer monsoon months (June to September) in Nepal and the rest of the months are almost dry. Wheat is cultivated during the dry winter period and therefore, the supplementary irrigation plays a vital role in its cultivation. Varieties of wheat have been developed to suit the local climatic conditions. Due to the availability of improved seeds, modern cultivation practice and a supplementary irrigation; the wheat cultivation has increased substantially throughout Nepal. The national area and production of wheat has remarkably increased from 228,000 ha to 706,481 ha and 193360 mt to 1,572,065 mt during 1970/71 to 2007/2008 respectively. Future planning to increase the wheat production in Nepal should give due consideration to the effect of global warming also. The present rate of annual increase of temperature was 0.06°C in Nepal. Trends of temperature rise were not uniform in Nepal. An increase of annual temperature at Bhairahawa during 1970-2008 was only 0.018°C. However, the wheat growing seasons at Bhairahawa, the trend of annual maximum temperature during November to April was -0.0068°C during the study period. Though modern facilities such as irrigation, improved seeds and fertilizers are available to some extent, weather and climate still plays an important role in the increase of area and production of wheat in Nepal
Prime Energy Challenges for Operating Power Plants in the GCC  [PDF]
Mohamed Darwish, Rabi Mohtar
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.51011

There is a false notion of existing available, abundant, and long lasting fuel energy in the Gulf Cooperation Council (GCC) Countries; with continual income return from its exports. This is not true as the sustainability of this income is questionable. Energy problems started to appear, and can be intensified in coming years due to continuous growth of energy demands and consumptions. The demands already consume all produced Natural Gas (NG) in all GCC, except Qatar; and the NG is the needed fuel for Electric Power (EP) production. These countries have to import NG to run their EP plants. Fuel oil production can be locally consumed within two to three decades if the current rate of consumed energy prevails. The returns from selling the oil and natural gas are the main income to most of the GCC. While NG and oil can be used in EP plants, NG is cheaper, cleaner, and has less negative effects on the environment than fuel oil. Moreover, oil has much better usage than being burned in steam generators of steam power plants or combustion chambers of gas turbines. Introducing renewable energy or nuclear energy may be a necessity for the GCC to keep the flow of their main income from exporting oil. This paper reviews the GCC productions and consumptions of the prime energy (fuel oil and NG) and their role in electric power production. The paper shows that, NG should be the only fossil fuel used to run the power plants in the GCC. It also shows that the all GCC except Qatar, have to import NG. They should diversify the prime energy used in power plants; and consider alternative energy such as nuclear and renewable energy, (solar and wind) energy.

Manish Kiran, Rabi Jee
Open Journal of Orthopedics (OJO) , 2012, DOI: 10.4236/ojo.2012.24027

Gap non-union of the tibia is frequently associated with deformity, infection and shortening. Ilizarov’s method of bone transport was used in the management of twenty-five cases of gap non-union of the tibia. The mean bone gap was 6.53 cm (range 4 to 12 cm). Union was achieved in all cases within a mean period of 11.12 months. The mean time taken for union, per centimeter of bone gap was found to be 1.7 months/cm. Pin tract infection was the commonest complication, seen in 9 cases (36%). The other complications encountered were neuropraxia (n = 3) deviation of the transported bone segment (n = 7), buckling of skin at the advancing side of bone (n = 4), traumatic corticotomy (n = 3), incomplete corticotomy (n = 1), equinus deformity (n = 4), knee stiffness (n

Rajbir Singh, Jagadeesh Panduri, Devendra Kumar, Deepak Kumar, Hardik Chandsana, Rachumallu Ramakrishna, Rabi Sankar Bhatta
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0072517
Abstract: Bacopa monniera is a traditional Ayurvedic herbal medicine used to treat various mental ailments from ancient times. Recently, chemically standardized alcoholic extract of Bacopa monniera (BM) has been developed and currently available as over the counter herbal remedy for memory enhancement in children and adults. However, the consumption of herbal drugs has been reported to alter the expression of drug metabolizing enzymes and membrane transporters. Present study in male Sprague-Dawley rat was performed to evaluate the effect of memory enhancing standardized extract of BM on hepatic and intestinal cytochrome P450 3A and P-glycoprotein expression and activity. The BM (31 mg/kg/day) was orally administered for one week in BM pre-treated group while the control group received the same amount of vehicle for the same time period. The BM treatment decreased the cytochrome P450 3A (CYP3A) mediated testosterone 6β-hydroxylation activity of the liver and intestine by 2 and 1.5 fold, respectively compared to vehicle treated control. Similarly pretreatment with BM extract decreased the expression of intestinal P-glycoprotein (Pgp) as confirmed by Western blot analysis but did not alter the expression of hepatic Pgp. To investigate whether this BM pretreatment mediated decrease in activity of CYP3A and Pgp would account for the alteration of respective substrate or not, pharmacokinetic study with carbamazepine and digoxin was performed in BM pre-treated rats and vehicle treated rats. Carbamazepine and digoxin were used as CYP3A and Pgp probe drugs, respectively. Significant increase in AUC and Cmax of carbamazepine (4 and 1.8 fold) and digoxin (1.3 and 1.2 fold), respectively following the BM pre-treatment confirmed the down regulation of CYP3A and Pgp.
Epidemic of Hysteria in a School of Rural Eastern Nepal: A Case Report
Rabi Shakya
Journal of Indian Association for Child and Adolescent Mental Health , 2005,
Abstract: IntroductionThe headmaster of a school (NRMV) in rural eastern Nepal, pleaded for help from the public health Departmentof Psychiatry, BKIHS, Dharan, Nepal, to prevent closure of his school as guardians of many students refused tosend their children to his school, which was supposedly haunted by evil spirits. The author, along with his staff,from Department of Psychiatry, BKIHS, visited the school and investigated the matter.FindingsThe first case involved a 16 years old girl, daughter of the head master of a school. After hearing the death of a“mad” (psychotic) woman, whom she had met 2 weeks ago, the girl developed a brief spell of disorganisedbehaviour beside the tube well in her school. Soon after, other girls manifested almost similar behaviour inschool at different places. In all 70 girls out 300 were afflicted with problem. Boys were spared. Out of 15 suchincidents investigated, only 3 cases were precipitated by stressful events. Even though they were heterogenousin terms of diagnosis, the victims and carers believed that they were all the same, the effect of the evil spirit ofthe “mad woman”.Education was the main intervention strategy. It focused on the nature of the problem (medical illness) and itsmanagement. This was done by delivering a series of lectures, distributing pamphlets, and appropriate coverageof the events in the local newspaper and radio stations. 6 months later, follow-up was undertaken. There wereonly 4 new incidents. Thus there was a marked reduction in the incidence of new cases by 3.4 / month.Conclusion: Classical mass hysteria still occurs in rural setting of developing countries. Planned psychoeducationis an effective intervention.

Abstract: controlled, randomized nonblinded clinical trial to assess the efficacy of amphotericin B deoxycholate as compared to pentamidine for the treatment of antimony unresponsive visceral leishmaniasis cases in Bihar, India Original Research (3569) Total Article Views Authors: Vidya Nand Rabi Das, Niyamat Ali Siddiqui, Krishna Pandey, Vijay Pratap Singh, Roshan K Topno, et al Published Date December 2008 Volume 2009:5 Pages 117 - 124 DOI: http://dx.doi.org/10.2147/TCRM.S3581 Vidya Nand Rabi Das1, Niyamat Ali Siddiqui2, Krishna Pandey3, Vijay Pratap Singh2, Roshan K Topno4, Dharmendra Singh5, Rakesh Bihari Verma2, Alok Ranjan2, Prabhat Kumar Sinha1, Pradeep Das6 1Department of Clinical Medicine, Rajendra Memorial Research Institute of Medical Sciences, Indian Council of Medical Research, Patna, Bihar, India; 2Department of Biostatistics; 3Department of Clinical Medicine; 4Department of Epidemiology; 5Department of Molecular Biology; 6Director and Institutional Head, Rajendra Memorial Research Institute of Medical Sciences, Indian Council of Medical Research, Patna, Bihar, India Background: There is significant variation in Amphotericin B (AMB) efficacy and relapses in antimony unresponsive visceral leishmaniasis (VL) cases over a period of time (10–15 years). Keeping in mind the above mentioned view this study was undertaken with an objective to assess the magnitude of cure and relapse rates of AMB in the treatment of antimony unresponsive VL cases. Methods: In a controlled, randomized nonblinded clinical trial, we evaluated the cure and relapse rate of Amphotericin B deoxycholate as compared to pentamidine. A total of 82 sodium stibogluconate (SSG) unresponsive and parasitologically confirmed VL cases were included in this study and randomized into two groups, test (Amphotericin B) and control (Pentamidine). Both the groups were treated with recommended dosages (as per World Health Organization guidelines) of respective medicines. All the patients were followed up on 1st, 2nd, and 6th month after end of treatment. Results: Apparent cure rate in the Amphotericin B group was found to be 95% (39/41) compared with 83% (34/41) in the Pentamidine group, which shows significant statistical difference (p = 0.05). The ultimate cure rate was found 92% (38/41) in the Amphotericin B group compared to 73% (30/41) in the Pentamidine group, which shows a significant statistical difference (Yates corrected chi-square = 4.42, p = 0.04). Similarly, significant statistical difference was observed in the relapse rate of the Amphotericin group compared to the Pentamidine group (p = 0.03). Conclusions: AMB may still be the drug of choice in the management of resistant VL cases in Bihar, India. This is due to its consistent apparent cure rate (95%), low relapse rate (2.5%), and cost effectiveness compared with other available antileishmanial drugs. It is a safe drug even in case of pregnancy. Efforts should be taken to form a future strategy so that this drug and coming newe

The utility solar power plants were reviewed and classified by two basic groups: direct thermal concentrating solar power (CSP) and photovoltaic (PV). CSP as Parabolic Trough Collector (PTC) of 100 MW solar power plants (SPP) is suggested and suitable to provide solar thermal power for Qatar. Although, LFC had enough experience for small projects, it is still need to work in large scale plant such as 100 MW and couple with multi effect distillation (MED) to confirm costs.

Abstract: Savanna grassland of Northern Nigeria is blessed with ample tree resources that were of ample benefits to mankind most of which their multi-purpose uses have been exploited, but still there are potential uses on the pipeline. Baobab (Adansonia digitata) tree have been identified as tree of multi-purpose use for a long period of time by rural and urban dwellers. This has made Baobab among the most important economic tree that receives meaningful attention. Uses as human food, animal fodder, medicine were among the major ones identified with it in the study area. Access to this tree is generally private, because of its importance, the tree is highly managed through regular pruning, fencing and planting new seedlings. It was recommended that Governmental and nongovernmental organizations should improve the tree and make it available to rural dwellers and farmers.
