A Critical Study of the Library Facilities Provided by the Private Engineering Colleges in Kolkata
Get PDFResearch study encompasses the library facilities provided by the engineering colleges to its stakeholders. To pursue this study, combination of methods was adopted step by step. The survey method was employed to collect the required data. A structured questionnaire was prepared and a sample study has been done for this purpose. Besides these, relevant data are collected from observation of the libraries, annual report of the libraries, etc. Quantitative data collected in this study were analyzed, using descriptive statistics. It also highlights the gaps between available library services and information demand of the users. Basically, the entire paper summarizes different areas associated with the library services, such as, the frequency of library use, type of library material used, standard of library documents, sources used for wanting required information, users’ satisfaction, etc. Finally, it is concluded that the library and information science professionals are to make them relevant by reaching out to users

Manuscript received 13 May 1992, accepted 16 July 1992
Xanthones isolated during the period 1980 to mid-1991 are tabulated under different classifications along with their plant sources. CMR data of xanthones in general have also been incorporated. The importance of xanthones as possible chemotherapeutic agents, has been discussed. In addition, the plant sources that are known to produce xanthones uptil now have been presented in a tabular form indicating the families to which they belong

is
very much important due to its major role in environmental pollution,
biomedical research, and food safety applications. In this study,
an electrochemical NO sensor has been fabricated using gold nanoparticle
(Au NP)-modified tungsten oxide (WO3) nanoflakes. WO3 nanoflakes were grown hydrothermally on fluorine doped tin
oxide (FTO) substrates, and Au NPs were attached by a photoreduction
method. The sensing characteristics of pristine WO3 and
Au NP-coated WO3 electrodes have been studied by amperometric
techniques. The sensor performance has been optimized at various Au
NP loadings. The optimized sensor demonstrated a high sensitivity
(∼39.37 μA cm–2 mM–1) over a wide linear range (∼10 μM to 5.78 mM) with
a low detection limit (∼0.12 μM). The Au NP-coated WO3 sensing electrode demonstrated high stability. The sensor
current only decreases 7.54% after 31 days of continuous measurements.
The sensor also showed fast response (1.7 s) and high selectivity
toward NO detection. NO detection in fruit samples (apple and orange)
has been studied with the Au NP-modified WO3 electrode
for fruit quality monitoring application
Phosphorus dose and potassium source on yield and export quality of potato
Get PDFSAARC J. Agric., 20(2): 199-210 (2022)In Bangladesh, potato (Solanum tuberosum L.) lacks optimum quality for export or processing
industries. Optimum utilization of specific plant nutrients can improve quality. The experiment
was conducted to evaluate the best dose(s) of phosphorus in combination with potassium sources
as they affect potato tuber quality. The experiment consisted the factors: phosphorus dose(4); P1
= 200 kg ha-1 TSP @ 42.55 kg ha-1 P; P2 = 220 kg ha-1 TSP @ 46.81 kg ha-1 P, P3 = 240 kg
ha-1 TSP @ 51.06 kg ha-1 P and P4 = 260 kg ha-1 TSP @ 55.32 kg ha-1 P, and potassium
sources (3); K1= KCl (250 kg ha-1 KCl @130 kg ha-1 K), K2 = KH2PO4 (452.19 kg ha-1
KH2PO4 @130 kg ha-1 K) and K3 = K2SO4 (288.6 kg ha-1 K2SO4 @130 kg ha-1 K). The
interaction of phosphorus doses and potassium sources affected most parameters studied. The
highest yield (35.35 t ha-1), caned (10.35 t ha-1), chips (28.06 t ha-1), and French fry (0.367 t
ha-1) were from P3K2, P4K2, P3K2, P3K1 respectively; the lowest yield (30.90 t ha-1), caned
(5.59 t ha-1) and chips (20.01 t ha-1) were from P1K3, P4K1, P1K3 respectively. The highest
dry matter (22.85%), starch (17.936%), antioxidant (630.12 Trolox μMol/100 g FW), and
polyphenol (92.994 GA mg/100 g FW) were from P1K3; the lowest reducing sugar (0.1713 mg
g-1 FW) and non-reducing sugar (0.3290 mg g-1 FW) were from P1K3. It appeared that 200 kg
ha-1 TSP @ 42.55 kg ha-1 P as a dose of phosphorus and K2SO4 as sources of potassium may
be a suitable combination to produce export and processing quality potato
