bananas are climacteric fruits and controlling ripening is effective in reducing loss. this experiment studied the effect of packaging (plastic bag, edible wax and plastic bag, plastic bag and 2 or 4 g/kg potassium permanganate) over 5 weeks of cold storage on the quality and characteristics of cavendish cultivar bananas. the samples were removed from storage at 8, 16, 24, 32 and 40 days and fr...
Overcroping, shading and short growing season can reduce the pool of carbohydrate reserves, and consequently reduce the quality of crop in grapevines. An experiment was conducted in order to study the effects of cluster number and different levels of cane topping on balanced yield and qualitative traits of table grape (Vitis vinifera L.) cv. Askari. The design of experiment was factorial in com...
اثر پنج نوع محلول غذایی با نسبتهای متفاوت نیتروژن آمونیومی به نیتروژن کل بر خصوصیات کیفی و کمیو غلظت عناصر نیتروژن، پتاسیم و کلسیم میوه سیب در ارقام گالا و گلاب در یک فصل رشد مورد مطالعه قرار گرفت. نسبت آمونیوم به نیتروژن کل در محلولهای غذایی شماره 1 تا 5 به ترتیبmeq l-1 03/0، 14/0، 10/0، 07/0، 04/0 بود. ph محلولهای غذایی روی 1/0± 5/6 تنظیم گردید و آزمایش بهصورت فاکتوریل در قالب طرح بلوکه...
the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
The waste generated by the dentist clinic is in form of non-medical and medical waste. Medical liquid containing blood can develop disease if not processing properly before entering environment. Aquaponic system a combination hydroponics aquatics, also resirculation process using plants animals as: convolvulus land (Ipoema Reptans) catfishes (Clarias spp.) that able to survive extremes. has pot...
STUDY DESIGN A retrospective observational study. OBJECTIVE We evaluated the prevalence and clinical characteristics of tandem spinal stenosis (TSS) in patients with cervical myelopathy including ossification of the posterior longitudinal ligament of the cervical spine (C-OPLL). SUMMARY OF BACKGROUND DATA Concurrent cervical and lumbar spinal canal stenosis is generally reported as TSS. Mos...
Wastewaters from three different sources, private residence (domestic), medical clinic (institutional) and polymer industry (industrial) were characterised for their pollution potentials. The results of analysis show pH of 7.6, 6.5 and 6.3 for domestic, institutional and industrial wastewater, respectively. The DO, BOD and COD was found to be 4.01, 66 and 114 mg/l for the domestic wastewater, 3...
Palm oil mill effluent (POME) is wastewater containing dissolved materials with concentrations above the threshold. Generally, POME processing in Indonesia uses an open pond system. It less efficient because it requires large areas and causing greenhouse gas effects. This research aims to improve processing, three methods were studied; bioremediation using enrich indigent lypholitics bacteria (...
Wetlands are land areas that are wet during part or all of the year. Constructed wetlands are man-made systems that mimic the functions of natural wetlands applied for wastewater treatment. The aim of this research is to investigate the feasibility of using a constructed wetland for treatment of kitchen waste water from hostel mess. The wetland plant species grown in the constructed wetland is ...
