Physical and mechanical properties of cement-bonded particleboard made from squander of paper

The objectives of this study were to assess and explain the usage of squander paper as a selective crude material in the production of cement-bonded particleboard (CBP) and to decide its physical and mechanical properties. The two treatment factors were used such as squander of paper types (A4 paper sheets, newspaper and cardboard) and CaCl2 as chemical accelerator agents (in concentrations of 2%, 4% and 6% according to the weight of cement) with proportions mixed of cement - squander of paper - water about 2.5:1:1,25. The result indicated that the squander of paper types and the concentration of CaCl2 have affected the physical and mechanical properties of CBP. The board which produced using cardboard with the proportions of materials (2.5:1:1.25) and accelerator CaCl2 about of 6% were satisfied all the requirement standard of JIS A 5417 1992 and have the most physical and mechanical properties values.

Promotion of Growth, Chlorophyll Content and Yield of Rice by a New Drug at Ultra High Dilution

Application of synthetic fertilizers reduces natural fertility of soil and contaminates ground water. Some photosynthesis inhibitors at ultra-high dilution (UHD) increase photosynthesis, growth and yield of crops. A weedicide Paraquat at UHD enhanced growth and yield of potatoes in fields. This weedicide was serially diluted with distilled water and manually succussed in 30 steps following the method of preparation of homeopathic dilutions called potencies. In this way the 30th potency of Paraquat called Paraquat 30cH was prepared and preserved in 90 % ethanol. Paraquat 30cH was diluted with water 1:1000 (v/v) and sprayed on rice plants in a field measuring 0.3125 acre. The control plot of the same area was situated 300 meters away from the test plot. Three treatments were given at an interval of 7 days. Treated plot showed increased growth, chlorophyll content and yield of rice significantly as compared to control. The UHD of the weedicide produced exactly the opposite effect of the crude material on plants. The increased growth and yield of rice by Paraquat 30cH may be due to enhancement of photosynthesis of treated plants. The UHD of Paraquat increased yield of rice by 19.35% over the control.

Spore Forming Bacteria Responsible for Food Spoilage: A Review

In this article we investigate about the different sort of spore framing microorganisms engaged with deterioration of different edibles either cooked or without cooked. The organisms which are exceptionally heat safe can be disconnected in low - corrosive canned nourishments.The species which are dominating species are by and large Geo bacillus stearothermophilus, Morellathermoacetica and Thermonaro bacterium spp. The items which are in pastry shop or distillery are explicitly ruined by Bacillus species. The primary microorganism revealed for ruining the bread kitchen stuffed food are Bacillus amyloliquefaciens. The different sorts of vacuum pressed meats which are refrigerated are exceptionally get ruined by Clostridium species. Milk is another crude material to be ruined effectively by the microorganisms, presently how it is being ruined by them? So essentially they make ascend in the measure of corrosiveness in the milk itself which makes the milk and its items much preceding turn sour without any problem. It is a direct result of the two genera which is been distinguished from milk when it goes through additional means like sanitization, cleansing, drying out or aging and furthermore likewise can be separated based on heat treatment and capacity temperature. In this review article investigation we came across many research papers. Different types of food and edibles are surveyed giving us various samples about different type of spoilage due to spore in them. We have examined various dairy products meat, fish, canned foods various bakery products and many more things. Our investigation showed that a slimy layer, foul smell sour odour, changes in the colour and structure, changes due to weather conditions proved as a boon for various bacterial spores to hit them with spoilage. This work concludes the study of all the above mentioned topics.

Shortage of Construction Materials A Case Study of Lahore, Islamabad and Peshawar, Pakistan

The fundamental focus of this qualitative study is to explore the contributing factors responsible for construction material shortage specifically in major cities of Pakistan's such as Lahore, Peshawar, and Islamabad. Further, the study has concentrated to discover the potential remedies to overcome the barriers resulting in a shortage of construction material availability. Data sampling methods are utilized to apprehend the participant’s opinion. The participant’s opinions were recorded to make them efficiently analyze through inductive thematic investigation. For sound results, the current condition of material shortage, relevant reasons, and deficiency of key items are examined in detail. The research findings proposed that the unavailability of materials is associated with the deficiency of a customary delivery system, fluctuations in demand, complications in the import of materials, significant expense, limited share portion in raw material, constrained suppliers of crude material, political clashes, administrative limitations, and maintenance of realistic prices. The result obtained, the recommended remedies are to extend flexibility and guideline for the manufacturers, the maintenance of realistic prices, and boosts the record control system, improvement in stock control framework, and establishment of a reserve system in the country. This study believes in contributing to the shortage of construction materials: a case study of Lahore, Islamabad, and Peshawar, Pakistan

Step-Economical C–H Activation Reactions Directed by In Situ Amidation

Owing to the inherent ability of amides to chelate transition-metal catalysts, amide-directed C–H activation reactions constitute a major tactic in directed C–H activation reactions. While the conventional procedures for these reactions usually involve prior preparation and purification of amide substrates before the C–H activation, the step economy is actually undermined by the operation of installing the directing group (DG) and related substrate purification. In this context, directed C–H activation via in situ amidation of the crude material provides a new protocol that can significantly enhance the step economy of amide-directed C–H activation. In this short review, the advances in C–H bond activation reactions mediated or initiated by in situ amidation are summarized and analyzed.1 Introduction2 In Situ Amidation in Aryl C–H Bond Activation3 In Situ Amidation in Alkyl C–H Bond Activation4 Annulation Reactions via Amidation-Mediated C–H Activation5 Remote C–H Activation Mediated by Amidation6 Conclusion

Financial Performance of Hi-Tech Arai Private Limited

Based on information examination done on investigation of money related execution of Hi Tech Arai it very well may be presumed that the organization's in general budgetary exercises is attractive. Since the greater part of the crude materials are being imported, the organization needs to keep up a support stock for crisis cases. So a great deal of reserve is put resources into crude material inventories which at last influence the liquidity and benefit of the worry and consequently the liquidity pattern of the organization is expanding step by step which is a decent marker. The organization the greater part of incomes from the fare things of different nations. They will urging the fare to the remote counters. The money and bank parity of the organization is declining so the organization must have an eye on it. Installment to the lenders is deferred because of the inaccessibility of money close by.

Materijalna baza proizvodnje – nekoliko napomena o virtualnosti

The difference between the “real,” “authentic” life and its mere representation has saturated the philosophical discourse from its very onset. Debord’s The Society of the Spectacle usually gets categorized as a further elaboration on this issue. The essential misapprehension of such an understanding lies in the disregard of Debord’s constitutive thesis: “the spectacle is not a collection of images; it is a social relation between people that is mediated by images.” (§ 4) In cultural perspectives, the “real” material dynamics of life – relations between people – is replaced by a purported exchange of images which lack any authenticity. The concept of cognitive capitalism (Vercellone, 2005), with its theses on the contemporary domination of information and knowledge within capitalist reproduction, further validates this opposition. According to Doogan’s (2009) thoroughly researched and empirically founded insights, our world is still heavily dominated by crude material production which precludes any notion of a new, post-Fordist, virtual, immaterial, post-work stage of capitalism. Similarly, Huws (2003, 2014) warns of the dubious status of the concepts of fluid identities, or hybrid subjectivities, and stresses the prevalence of class and gender issues which still substantially affect the working spheres. Drawing on Davis’s (2013) insights on the necessity of class analysis for the comprehension of the artistic field, I will present the modes in which “creativity” functions as a neoliberal buzzword. More specifically, I will outline the ways in which systemic exploitation, as an intrinsic feature of capitalism, still structures the dynamics of the art field, particularly areas that are fashionably known as “creative industries”.
