Abstract:

The purpose of this note is to outline a system of celestial navigation which is both decimal and coherent. In a decimal system there can only be one unit, with its decimal multiples and submultiples, for measuring any quantity. It follows that a decimal system of celestial navigation requires one unit for measuring time and one unit for measuring arc. In a coherent system these units must be related by a factor of one.

Abstract:

Decimal digit number computation, through bit compression methodology, offers space and time saving, which can be incurred by the Chen-Ho and Densely Packed Decimal (DPD) coding techniques. Such coding techniques have a property of bit compression, like, three decimal digits can be represented by 10 bits instead of 12 bits in binary coded decimal (BCD) format. The compression has been obtained through the elimination of the redundant 0’s from BCD representation. This manuscript reports the pros and cons of the techniques mentioned above. The logic level functionalities have been examined through MATLAB, whereas circuit simulation has been erified through Cadence Spectre. Performance parameters (such as delay, power consumption) have been evaluated through CMOS gpdk45 nm technology. Furthermore, the best design has been chosen from them, and the decimal adder design technique has been incorporated in this paper.

Abstract:

This essay examines the problem of basqaqs and the Mongol decimal system in Appanage Rus’. It surveys the functions of the basqaqs or daruγas and the importance of the divisions of ten thousand and thousands in the Mongol Empire. In Appanage Rus’ the decimal system was of less importance for the organization of the Rus’ian armies than it was for the administration of the tribute and the collection of other taxes, especially on the local rural level. In Rus’ the Mongol division of ten thousand (tümen) was separated from its military connotations and became associated with the rural district of the volost and rural officials known as the hundredmen and tenmen. The essay reviews the various functions the hundredmen played in Europe and their place, together with the tenmen, in Appanage Rus’ for the collection of the tribute. At the same time, the thousandman or chiliarch gradually disappeared in northeastern Rus’.

Abstract:

AbstractThis article traces the idea of decimalized systems of time reckoning, from their first articulated designs and implementation in the French revolution to our day. The paper analyzes how decimal time was the product of a broader rationalizing project that successfully reformed weights and measures (with the invention of the decimal metric system) and money (with the introduction of the franc as a decimal currency), but failed in bringing the chronological and calendrical reform into fruition. Finally, some hypotheses are suggested to explain why contrary to the global success of the metric system and decimal currency, plans for a fully decimalized time system were never accepted.

Abstract:

The number system is the representation method of numbers, and number system conversion is the most basic function of a computing system. The decimal system is the most commonly used number system; however, it may not necessarily be the most suitable number system in a computing system. This paper investigates the conversion methods between different number systems and designs corresponding cells, such as P systems, to implement them. The P systems we designed include Π10_2 and Π2_10 to implement conversion between decimal and binary, Π10_m and Πm_10 to implement conversion between decimal and m-base. The operation process of each P system was explained through examples, and their feasibility and effectiveness were verified through simulation software, UPSimulator.

Abstract:

The 1/Z expansion for the ground state energy of the Coulomb system of an infinitely massive center of charge Z and two electrons (two-electron ionic sequence) is studied. A critical analysis of the 1/Z coefficients presented in Baker et al. (Phys. Rev. A, 41, 1247 (1990)) is performed and its numerical deficiency is indicated, leading, in particular, to unreliable decimal digits beyond digits 11–12 of the first coefficients. We made a consistency check of the 1/Z-expansion with accurate energies for Z = 1–10: the weighted partial sums of the 1/Z expansion with Baker et al. coefficients reproduce systematically the ground state energies of two-electron ions with Z ≥ 2 up to 12 decimal digits and for Z = 1 up to 10 decimal digits calculated by Nakashima and Nakatsuji (J. Chem. Phys. 127, 224104 (2007)) with unprecedented accuracy. This rules out the presence of non-analytic terms at Z = ∞ contributing to the first 10–12 decimal digits in the ground state energy; it agrees with the Kato theorem about convergence of the 1/Z expansion within that accuracy. The ground state energy of two-electron ions Z = 11 (Na9+) and Z = 12 (Mg10+) is calculated with 12 decimal digits. This study can be considered as the independent confirmation of the correctness of 10 decimal digits in all 401 coefficients of 1/Z-expansion printed in Baker et al. (Phys. Rev. A, 41, 1247 (1990)).

Abstract:

Long, almost 3500 years delay was observed, until the notion of positional number system originating from Babylon was introduced in Western Europe and, afterwards, in aIl over the modern world. This proves that acquaintance with such a complex concept as decimal fraction is must be started long before the arithmetic of decimal fractions is introduced. Teachers working experience using A. Bakštys and G. Bakštys textbook [5] in the 5-th grade is described in this paper.

Abstract:

Abstract In this paper we compare the efficiency of the decimal system to the efficiency of different mixed radix representations. We use as a starting point for our study the duodecimal systems suggested by Pascal and the Maya “Long Count” system. Using the quality index we experimentally show that two slight deviations from the duodecimal system are more efficient than the previous two systems and also than the decimal system.

Abstract:

How do we foster computational fluency with rational numbers when this topic is known to pose so many conceptual challenges for young students? How can we help students understand the operations of rational numbers when their grasp of the quantities involved in the rational-number system is often very limited? Traditional instruction in rational numbers focuses on rules and memorization. Teachers often give students instructions such as, “To add fractions, first find a common denominator, then add only the numerators” or “To add and subtract decimal numbers, line up the decimals, then do your calculations.”

This Paper Presents a Classification System for Managing and Indexing Hardcopy Engineering Drawings, Referred to, in this Paper, as Drawings Library Management System (DLMS), Developed for an Appropriate Technology Research Centre in Botswana. the System Is Akin to Common Library Cataloguing and Classification Systems such as the Dewey Decimal Classification (DDC), Universal Decimal Classification and Others, which, though Are Well-Known and Have Been around for many Years, Are yet to Be Exploited for the Classification and Management of Paper Drawings. in Fact, Hardcopy Drawings Appear to Be Neglected Compared to the Softcopy Type, for which Various Scholarly Articles Have Been Done on their Classification, Retrieval and Management. this Is Unfortunate as, Invariably, it Is Hardcopy/paper Drawings that Are Mostly Used in Production, Especially in Developing Countries where the Power of CAD/CAM Is yet to Be Fully Harnessed. Accordingly, the DLMS, a Model Successfully Used in a Research Centre in Botswana for over Ten Years Is Proposed.The System Was Further Analysed against and Compared to Three Main Library Classification Systems, Namely, the Dewey Decimal, the Universal Decimal and the Library of Congress Systems. Results Show that the DLMS Is a Better Classification System for Managing Hardcopy Drawings.

Abstract:

A study was conducted to assess the effects of different kinds of inorganic fertilizers on the production of fishes in six ponds during October to December 2011. There were three treatments with two replications under each treatment and each of the ponds was stocked with 80 fish fry. In treatments I, II and III, ponds were fertilized fortnightly @ urea 100 g decimal-1, T.S.P. 100 g decimal-1 and urea 50 g decimal-1 + T.S.P. 50 g decimal-1, respectively. Selected water-quality parameters of ponds under study were more or less similar and within the productive range. Mean phytoplankton and zooplankton densities under treatments I, II and III were 57.08 ± 1.35, 8.80 ± 0.09 and 77.29 ± 3.72, 12.88 ± 0.74 and 98.93 ± 1.61, 16.16 ± 1.75 (x103) cells L-1, respectively. The net and gross fish productions of the ponds under treatments I, II and III were 0.85 and 3.11 t ha-1 yr-1 and 1.32 and 3.58 t ha-1 yr-1 and 1.85 and 4.11 t ha-1 yr-1, respectively. Fish production under treatment III was better than those under treatments I and II because plankton population densities under treatment III was the highest. Therefore, the mixed fertilization is suitable for production of plankton that enhance growth and production of fishes. DOI: http://dx.doi.org/10.3329/ijarit.v4i2.22639 Int. J. Agril. Res.

Abstract:

In the past, the CN was determined through SCS handbook. In order to determine runoff prediction using SCS-CN model, selection of CN is important. However, the conventional CN methodology with inappropriate CN selection often produces inconsistent runoff estimation. Thus, the new direct curve number derivation technique based on rainfall-runoff datasets with supervised numerical optimization technique under the guide of inferential statistics was developed to improve the accuracy of surface runoff prediction. Furthermore, the two decimal point CN system was proposed in this study. The optimum CN of Melana site is 90.45 at alpha 0.01 with BCa 99 % confidence interval range from 90.45 to 95.12. The regional specific calibrated SCS-CN model with two decimal point CN derivation technique is out-performed the runoff prediction of conventional SCS-CN model and the asymptotic curve number fitting method.

Abstract:

The objective of this research was to assess the status of cattle in respect of breeding system, quality of breeding services, their production, reproduction, health status, management system and marketing system using an in-depth baseline survey. The mean of homestead land owned by the farmers was 36.17± 32.94 decimal and most of them (48.3%) own very low homestead land (11-50 decimal). Average cultivable land owned was found as 101.52±61.044 decimal and a considerable number of farmers have medium (51-150 decimal) to high (151 onward decimal) land area. From the collected data, it is clear that most of the households have cattle and chicken. But among cattle owners, about 77.62% have lower number (1-3). Most of the farmers 69.8% use locally available grass and only 3.2 % fed exotic grass to their cows. Milk sale and consumption (52.13%) was found as main objective behind cattle rearing. Semi-intensive method of rearing was found most acceptable (77.62%) among the peri-urban farmers. Disease problem was quite high because of lack of routine vaccination where vaccination was found to be practiced by only 38.46% farmers. Indigenous cattle are of high preference among the farmers (52.45%) because of its easy management and high resistance to disease, 41.2% percent farmers preferred crossbred cattle. Main reasons behind preference for Deshi cattle were easy management (24.48%) and lower feed requirement (12.59%) whereas, reason behind crossbred preference (35.66%) was higher milk production. Artificial Insemination (AI) was preferred (61.06%) over natural service (38.94%). For artificial insemination, semen of Holstein Friesian (43.07%) was preferred where Deshi was the second most choice (32.12%). Most of the farmers (82.9%) have no idea about genotype, quality & merit of semen. Average milk yield of Deshi and crossbred genotype were found as 1.72±0.80 and 6.65±5.05 liter per day respectively whereas lactation period and dry period were found respectively as 243.98±113.13 and 92.37±63.14 days in crossbred, 249.69±106.93 and 96.58±32.06 days in Deshi cows.

Abstract:

The article describes in detail the methods of extracting square and cube roots in the binary number system. The method for extracting the square root of a binary number is similar to the corresponding method for decimal numbers, which is called the "column method". As for decimal numbers, when choosing the next digit of the root, twice the current value of the root, represented in the binary system, is used. When extracting the cube root (also "column"), there are two differences from the decimal system. The first is that instead of 300 (the product of 3 and 100), the binary number 1100 is used (that is, the product of the binary equivalents of the numbers 3 and 4). The second difference is that instead of the number 30 (the product of 3 and 10), the binary number 110 is used (that is, the product of binary analogs numbers 3 and 2). To facilitate the selection of the next root digit (0 or 1), a number of standard values have been calculated, depending on the current root value. Assignments for independent work of students are offered.

Abstract:

An experiment was conducted to determine the impacts of fish population density on the growth and production of sarpunti (Barbonemus gonionotus), mrigal (Cirrhinus mrigala) and tilapia (Oreochromis niloticus) in polyculture system for a period of 90 days in six earthen pond .The experiment was carried out under three treatments each with two replications. The stocking density was 50 fish per decimal (sarpunti 20, mrigal 20 and tilapia 10) under treatment-I, 75 fish per decimal (sarpunti 30, mrigal 30 and tilapia 15) under treatment-II and 150 fish per decimal (sarpunti 60, mrigal 60 and tilapia 30) under treatment- III and all the ponds under three treatments supplementary feed was not used. The average initial length and weight of the fingerlings of sarpunti, mrigal and tilapia were 13.29 cm, 12.80 cm, 4.55cm and 22.7g, 23.75g and 3.84 g respectively. The ponds were fertilized fortnightly with cowdung, urea and TSP at the rates of 5 kg, 100 g and 200g per decimal, respectively. Mean survival rates of fish under treatment-I, treatment-II and treatment-III were 87.50%, 88.16% and 81.30% respectively. The specific growth rates (SGR, % per day) of fish under treatment-I, treatment-II and treatment-III were 1.13%, 1.03% and 0.80%. The calculated net fish production of the ponds under treatment-I was 1.61 ton/ha/yr and that of the ponds under treatment-II was 1.97 ton/ha/yr and 2.5 ton/ha/yr in treatment-III.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22095 J.

This article describes and identifies the personal meanings that the multigrade schoolteacher has in the teaching of the decimal metric system, through the facets of didactic mathematical knowledge. In various investigations supported by this theory, the need to apply the notion of facets or didactic suitability as an instructional process in which teachers are knowledgeable and competent in an academic setting, has been visualized. In this sense, the research is framed in teachers of different areas of knowledge that guide mathematics in which ten teachers participated. The data collection is based on the analysis of a diagnostic test and a semi-structured interview. Finally, as one of the relevant results of the research, three epistemic configurations are obtained from the personal meanings identified in the teachers interviewed.

Abstract:

The article discusses the concept of "decimal number system". Based on the analysis of a number of sources, it is concluded that this concept can be used in two cases: 1) when 10 characters (numbers) are used to write numbers, this option will be positional in nature; 2) when the number is represented as signs corresponding to powers of 10 (this will be a non-positional decimal system). In this regard, such a concept of informatics as "mixed number system" is also specifed. It is argued that we can talk about two types of mixed number systems: 1) "mixed" in terms of the positional nature of individual systems; 2) "mixed" in terms of the basis of individual systems. Attention is drawn to an erroneous example of a mixed number system given in a number of sources related to school informatics (on teacher sites, forums, etc.) and on the popular Wikipedia website.

Abstract:

Abstract Introduction/Objective Our multi-hospital system recently adopted uniform use of 2 decimal places for reporting of creatinine (mg/dL), in accordance with NIH guidelines. Surprisingly, this change in patient reports fostered complaints from clinicians. Use of 2 decimal places is both analytically appropriate and reduces imprecision in calculations of estimated glomerular filtration rate (eGFR). Primary literature is devoid, however, of a delineation of the scale of the effect of using 1 vs. 2 decimal places to calculate eGFR. We examined this effect for both the Modified Diet in Renal Disease (MDRD) and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) eGFR equations. Methods/Case Report Creatinine is an input to a single multiplicative creatinine factor in eGFR calculations for MDRD and CKD-EPI equations. We calculated the creatinine factor for these equations for creatinine=0.6-10 mg/dL, and evaluated the % difference in this factor when using increments of 0.1 mg/dL (1 decimal place) compared to increments of 0.1±0.05 mg/dL (viz., the 2 decimal place boundaries of a rounded 1 decimal place report). The observed % differences reflect those that would be observed in associated eGFR results. Results (if a Case Study enter NA) Input of 1 vs. 2 decimal places for creatinine in eGFR calculations, using either MDRD or CKD-EPI, produces differences in eGFR of greater than ±5% only for creatinine <1.2 mg/dL, and greater than ±10% only for creatinine <0.6 mg/dL (MDRD only). These ranges for creatinine are within or near-to reference ranges for both males (0.7-1.4 mg/dL) and females (0.6-1.0 mg/dL), and encompass approximately 70% of all patient reports for our patient population. For comparison, eGFR has a 95% confidence interval of approximately ±30% across all eGFR’s. Conclusion The ±5% reduction in precision in eGFR for such a large fraction of results by use of only 1 decimal place for creatinine was deemed unwarranted. Clinician complaints were handled by one-to-one discussions.

Abstract:

The authors analyze the process of transmission of discrete messages in a residue number system, i.e., the efficiency of the representation of decimal numbers in a residue number system for different values of the module, that is. It is noted that it is characteristic of modern information transmission systems that the information is contained in the information parameter at a fixed interval of the Nyquist element. The increase in the capacity is achieved by increasing the number of states of the information parameter in this interval, i.e., the number of different amplitudes, phases and frequencies of the carrier oscillation. In addition, using a residue number system when representing decimal numbers, the sum of the digits of individual numbers in most cases is less than 10 (except for the number N104) and an increase in the probability of not using moduli Е 3; 5; 7 leads to an increase in the entropy of the corresponding events.

Abstract:

Objective – To determine the extent to which knowledge is currently addressed by the Library of Congress (LCC), Dewey Decimal (DDC), and Universal Decimal (UDC) classification systems. Design – Comparative analysis of the LCC, DDC, and UDC systems using Zin’s 10 Pillars of Knowledge. Setting – The Faculty of Philosophy and Science at a Brazilian university. Subjects – Forty one subject-related classes and 386 subclasses from the first two levels of the LCC, DDC, and UDC systems. Methods – To evaluate the LCC, DDC, and UDC systems, the researchers employed the 10 Pillars of Knowledge, a “hierarchical knowledge tree” developed by the lead author of this study (p. 878). According to the authors, the 10 Pillars of Knowledge seek to illustrate relationships between fields of knowledge while capturing their breadth. The first level of the Pillars consists of the following categories: Knowledge, Supernatural, Matter and Energy, Space and Earth, Nonhuman Organizations, Body and Mind, Society, Thought and Art, Technology, and History. Each of the 10 Pillars is further subdivided, resulting in a four level hierarchical structure of 76 categories. Of the 76 categories, 55 are unique subject areas. A selection of subject-based classes and subclasses from the first two levels of the LCC, DDC, and UDC systems were then mapped to the relevant subclasses within the Pillars. Analysis was limited to the first two levels of LCC, DDC, and UDC, except for the LCC categories of BF and BL where further subclasses were analyzed. Classes or subclasses in LCC, DDC, or UDC that were not subject based (for example, those based on publication type) were excluded from the study. In total, 41 main classes and 386 subclasses from LLC, DDC, and UDC were categorized using the 10 Pillars. Main Results – The LLC, DDC, and UDC systems were deemed to be complete and systematic in their coverage of only three of the 10 Pillars: Matter and Energy, Thought and Art, and History. This means that there was at least one class or subclass in each of the three systems that corresponded to the subclasses in these pillars. The remaining seven pillars were only partially covered by the three systems to varying degrees. For example, the coverage of religion in LCC and DDC show evidence of a bias towards Christianity and incomplete coverage of other faiths. In addition to the lack of completeness in terms of subject coverage, the researchers found inconsistencies and problems with how relationships between subjects were illustrated by the systems. For example, botany should be a subclass of biology, but the subjects occupy the same level in the LCC, DDC, and UDC systems. Researchers also noted cases where subclasses on the same level were not mutually exclusive e.g., the BR (Christianity) and BS (The Bible) subclasses in LCC. Overall, LLC performed slightly better than DDC or UDC, covering 47 of the 55 unique subject categories in the 10 Pillars. It was followed by UDC with 44 out of 55, and DDC with 43 out of 55. Some of the 55 unique subject categories in the 10 Pillars system were not represented by any of the systems: 3 subclasses under Society (Society at Large – Area Based, Social Groups – Age, and Social Groups – Ethnicity), 2 under Technology (Technologies – Materials and Technologies – Processes), and 1 under Foundations (Methodology). Conclusion – The researchers conclude that none of the three major classification systems analyzed provides complete and systematic coverage of the world of knowledge, and call for the library community to move to new systems, such as the 10 Pillars of Knowledge.

Abstract:

The article describes a number of little-known methods for translating natural numbers from one number system to another. The first is a method for converting large numbers from the decimal system to the binary system, based on multiple divisions of a given number and all intermediate quotients by 64 (or another number equal to 2n ), followed by writing the last quotient and the resulting remainders in binary form. Then two methods of mutual translation of decimal and binary numbers are described, based on the so-called «Horner scheme». An optimal variant of converting numbers into the binary number system by the method of division by 2 is also given. In conclusion, a fragment of a manuscript from the beginning of the late 16th — early 17th centuries is published with translation into the binary system by the method of highlighting the maximum degree of number 2. Assignments for independent work of students are offered.

Abstract:

In a positional number system, the numerical value of each symbol depends on its position in the sequence of digits representing the number. Any integer greater than 1 may serve as a base, and in a base b system there are b digits represented conventionally by the digits 0,1,2,..., b-1. In this paper we introduce the following four positional number systems: decimal (base-10), binary (base-2), Octal (base-8) and hexadecimal (base-16). We focus on representations of these number systems together with arithmetical operations defined on them. The study of this paper ends with the conversions of number from one system into another with examples.

Abstract:

The processing conditions of computer numerical control (CNC) equipment are learned through practical experience over many years. However, it is currently difficult to train professional experts in the field of machining because of the “demographic cliff” phenomenon. To solve this issue, it is necessary to study how to transfer the experience of current experts to new people who desire to use CNC equipment. An “expert system for CNC equipment” is proposed using artificial neural networks (ANNs) and machine-learning data is made available in decimal rather than binary so that mechanical engineers can easily access artificial intelligence. Assuming that an aluminum alloy (AL6063) is machined by a beginner using a lathe, when the tensile strength, cutting speed, and desired surface roughness are input into the ANN, the rotation speed (revolutions per minute) of the spindle and the feed rate are output by the proposed expert system for CNC equipment setting. This study demonstrates that decimal data about aluminum can be used for learning by an ANN, and it is judged that learning by using decimal data is possible for various materials and in various processing situations.

Abstract:

The article is devoted to the analysis of the ethnic composition of the population of the north-western districts of Novgorod land according to the toponymy and anthroponymy of the cadastres of the Vodskaya Pyatina 1499/1500. Orekhovsky district had several areas where the Baltic-Finnic oikonyms and anthroponyms were concentrated - these were Korboselsky district in the north of the Neva, Lopsky and Terebuzhsky districts in the southern Ladoga, as well as Dudorovsky and Izhora districts south of the Neva. The presence of Karelians is noted in the north of the Neva and in southern Ladoga. On the southern coast of Ladoga there were districts of the Ladoga district, where the Baltic-Finnish oikonymy is also found. Its percentage is declining to the east, towards the city of Ladoga. An analysis of the cadastres of the Koporsky, Yamsky and Novgorod districts allows us to conclude that the Baltic-Finnic onomastic tradition was concentrated primarily in the Toldozhsky and Kargalsky districts. This area is bordered by the valleys of the rivers Toldoga, Suma and Sista, the northwestern part of the Izhora plateau and the Soikinskiye hills. Slavic naming prevailed throughout the Vodskaya Pyatina. It turns out that in the villages where the Baltic-Finnish population lived, there was the so-called decimal system, the lowest governing layer of which was the decimal. As anthroponymy and oikonymy show, some of the decimals must have belonged to Votes and Izhora. In the middle of the 15 century Votes and Izhora had their own nobility, which is called «boyars». This nobility was incorporated into the socio-political system of Novgorod.

Laser point set has a massive quantity of data, which not only increases system load, but greatly reduces the follow-up processing efficiency as well. Considering the difficulty of mass point cloud data organization and management, grid index of point cloud data based on the decimal linear quadtree is proposed in this paper, point cloud data is segmented and encoded by means of linear quadtree based on decimal system, which will be stored in SQL Server, then, we can block and index point cloud in terms of Morton code or rectangular region, combine with the advantages of both spatial index and database to manage point cloud efficiently and safely. The results show that the proposed method ideally solves the problem of point cloud data organization and management.

Abstract:

Recording devices formed of knotted cords, known askhipus, are a well-known feature of imperial administration among the Inka of Andean South America. The origins and antecedents of this recording system are, however, much less clearly documented. Important insights into that ancestry are offered by a group of eight khipus dating from the later part of the Middle Horizon period (AD 600–1000), probably used by the pre-Inka Wari culture of the central Andes. This article reports the AMS dating of four of these early khipus. A feature of the Middle Horizon khipus is the clustering of knots in groups of five, suggesting that they were produced by a people with a base five number system. Later, Inka khipus were organised instead around a decimal place-value system. Hence the Inka appear to have encountered the base five khipus among Wari descendant communities late in the Middle Horizon or early in the Late Intermediate period (AD 1000–1450), subsequently adapting them to a decimal system.

Abstract:

The experiment was conducted to determine the effects of population densities of tilapia (Oreochromis niloticus) on the growth and production of tilapia in monoculture system. Fish population density was 80 fish per decimal under treatment-I, 160 fish per decimal under treatment-II and 320 fish per decimal under treatment-III. In the ponds under three treatments supplementary feed was not used. The average initial length and weight of the fry of tilapia was 4.48 cm and 0.067 g, respectively. The ponds were fertilized fortnightly with urea and TSP at the rates of 60 g, and 90 g per decimal, respectively. Mean survival rates of fish under treatment-I, treatment-II and treatment-III were 91.12%, 82.82% and 66.23%, respectively. The specific growth rates (SGR, % per day) of fish under treatment-I, treatment-II and treatment-III were 5.49%, 4.95% and 4.61%, respectively. The calculated net fish production of the ponds under treatment-I was 2.65 ton ha-1 yr-1 and that of the ponds under treatment-II was 2.55 ton ha-1 yr-1 and that of the ponds under treatment-III was 2.68 ton ha-1 yr-1. The net fish production under treatment-I and treatment-III were 2.65 ton ha-1 yr-1 and 2.68 ton ha-1 yr-1 higher than that of treatment-II, taking net fish production under treatment-I for 100%. According to survival rates and specific growth rates treatment-I is the best. So, the population density of 80 fish per decimal (under treatment-I) might be considered the best among the three treatments. Int. J. Agril. Res. Innov. Tech. 9(2): 76-83, December 2019

Abstract:

Children learn much mathematics in everyday life. When they buy things, for example, they have to count their money and calculate their change. Counting money is a special type of counting. On the one hand, when children count objects, they establish a one-to-one correspondence bet ween objects and number words; only absolute value, as opposed to relative value, is involved. On the other hand, when counting money children must bear in mind both types of value; while they deal with the coins one by one (absolute value), they must also take into account the relative value of the coins. Counting money thus helps children understand the decomposition of numbers; a large amount (for example, sixty-eight) is made up of smaller amounts—tens and ones—that can be repeated (six tens and eight one). All these ideas—relative and absolute value, decomposition, and repetition of equal values—are basic both to the understanding of the decimal system and to the undertanding of important properties of arithmetic operations.
