Preparation of Manuscript

General Requirement:

Prepare manuscripts preferably using MS Word, double spaced, on an A4 (210×297 mm) page format. Do not leave extra space between paragraphs .Only a single font (e.g., Times New Roman) should be used in 12 point or over. All manuscript sheets must be numbered successively at the mid of the bottom. The continuous line number throughout the manuscript should be given. Abstract, tables, and figure legends should be on separate sheets. Normally all parts of a manuscript should not exceed 40 pages. Use lettering of professional quality for drawings. Typewriter labels are unacceptable. Manuscript style should conform to that of recent issues and IJTHF manuscript format can be downloaded and available for authors.

Manuscript Structure:

The desirable organization of manuscript is as follows: Title Page, Abstract & Keywords, Introduction, Materials and methods, Results, Discussion, Acknowledgements, References, Tables, Figure Legends and Figures. Results and Discussion could be combined.

Title page: Provide contribution type of manuscript (e.g., full article, review, short communication, etc.), a full title of the article, a short one for use as a running head, and full names and affiliations of all the authors. If some of the authors are in different affiliations, place numbers as superscripts 1, 2, 3 … after the surname of authors and before the name of their affiliations. Place an asterisk (*) after the name of the corresponding Author. At the bottom of the title page, give full contact information (the name, telephone and fax numbers, and e-mail address) for the corresponding author.

Abstract and Keywords: On a separate page, an abstract of the manuscript should provide a clear and succinct statement (not exceeding 300 words). Authors should avoid non-standard abbreviations, unfamiliar terms and symbols and references. Keywords should be given at the end of the abstract in 4 to 6 words or phrases.

Main Manuscript: The manuscript will generally include an Introduction, Materials and methods, Results (or Results and Discussion), a Discussion and/or Conclusion, and Acknowledgments, but some manuscripts (e.g., reviews) may follow a somewhat different format. Following the main body of the manuscript, the following information should be provided (in order):

  1.  Full references for all literature cited (see below for specific instructions on citation)
  2.  Tables
  3.  Figure captions and legends
  4.  Figures (one table or figure per page)

References: References should be cited in the text at the appropriate places. All references cited in the text should be listed at the end of the text on a separate page, and arranged in alphabetical order according to the name of the first author. Cite all references in parentheses in the text by last name and year of publication [e.g., (John 2008) and (John and Rui 2004)]. When there are more than two authors, the reference should be cited using the first author’s name, followed by “et al.” [e.g., (John et al. 1997)]. When multiple sources are cited together, the references should be listed in chronological order from the earliest to the most recent [e.g., (John and Rui 2009; John et al. 1997; Rui 2010a, 2010b; Mark 2011; Lin 2012)]. Cite an article as “in press” only if it has been accepted for publication and cite the journal in which it will appear. References should be arranged in alphabetical order by year in the “References” section. Do not list unpublished data, articles in preparation, articles in review, and personal communications in the “References” section, but refer to them parenthetically in the text [e.g.,(John, personal communication)]. Reference information should be listed as follows:

Tables: All tables should be made with MS-word files or. Tables should be numbered consecutively with Arabic numerals, and referenced in the text in an appropriate location. Each table should have a concise heading, should be typed on a separate sheet of paper, and must have an explanatory title and sufficient explanatory material. Ruling in tables, especially vertical or oblique line should be avoided. Please use the table function in your word processor to build tables so that the cells can be easily re-sized to fit the page by the typesetters. Never use the Tab key to type tables, nor use space bar to adjust space. Use lower case letters in super- scripts a, b, c … for special remarks.

Figures: Figures should be made with JPG, GIF,  EMF, TIFF or PowerPoint files and numbered consecutively with Arabic numerals, and referenced in the text (e.g., Fig. 1, Fig. 1A-C, Figs. 1, 2) in an appropriate location. All figures should be termed “Figures” (not “plates,” but it is allowed in the supple- ments) and labeled with numbers. Within each figure, labels should begin from A, B, C, a, b, c, ••••. The preferred location of the figures should be indicted in the margin of the manuscript. Figures in color may be published at the author’s expense. Figures and illustrations should be prepared professionally.

Additional requirements to consider

Supplementary data:

The IJTHF accepts electronic supplementary material to support and enhance your scientific research. Supplementary files supplied will be published online alongside the electronic version of your article in IJTHF. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file.

Nomenclature and Units:

Scientific Names: The full formal Latin name for a taxon (e.g., Catla catla) should be provided the first time that the taxon is mentioned, and should be italicized. In sub- sequent sentences, the scientific name of all taxa in the samegenus should be abbreviated to the first initial of the generic name and the species name (e.g., C. Catla), except where this usage creates confusion or ambiguity. When common names are used, the scientific name should be provided the first time the taxon is mentioned in the abstract, and again the first time that taxon is mentioned in the main manuscript [e.g., nut pine (Catla catla)].

Abbreviations:

Abbreviations for SI units, common molecular, chemical, immunological, and hematological terms can be used without definition in the title, abstract, text, ta- bles, and figure legends (e.g., bp, kb, kDa, DNA, cDNA, RNA, mRNA, PCR, SDS-PAGE, ELISA, IgG, RBC, and WBC). Other common abbreviations are as follows (the same abbreviations are used for plural forms): hr (hour; use 0-24:00 h for time), sec (second), min (minute), day (not ab- breviated), week (not abbreviated), month (not abbreviated), year (not abbreviated), L (liter), mL (milliliter), μL (microliter), g (gram), kg (kilogram), mg (milligram), μg (microgram), ng (nanogram), pg (picogram), g (gravity; not × g), n (sample size), SD (standard deviation of the mean), SE (standard error of the mean).

Units:

The International System of Units (SI) should be employed for measurements. When one unit appears in a de- nominator, the unit should be presented as a fraction (g/m2); for two or more units in a denominator, use negative ex- ponents (g m-2 d-1). Insert one space between figures and units, except for % and units of temperature, latitude, and longitude (e.g., 5 m, 55 ºC, 500 kg). Times of day should be presented using a 24 hour clock (e.g., 0800 hr, 2.030 hr). Dates should be presented as for example, 31 Jan 2012. In the text, numbers should be Arabic numerals, except when beginning a sentence. Numbers greater than 999 should have commas (e.g., 10,000).

Statistical Conventions:

Means and standard errors/standard deviations should be presented with their associated sample sizes (e.g., mean ± SD = 18.0 ± 1.5 g, N = 75). For significance tests, provide the name of the test, the test statistic and its value, the degrees of freedom or sample size, and the p-value, separated by commas (e.g., Mann-Whitney U test, U = 41, N1 = 3, N2 = 22, p < 0.05). For tests with which degrees of freedom are traditionally presented, present the degrees of freedom in subscript (e.g., ANOVA, F2, 22 = 5.72, p = 0.01).

Proofs:

The IJTHF provides corresponding author with galley proofs for their correction. Corrections should be kept to minimum. The editor retains the prerogative to question minor stylistic alterations and major alteration that might affect the scientific content of the paper. Fault found after publication is a responsibility of the authors. The corresponding author may be contacted by IJTHF Editorial Office, depending on the nature of correction in proof. If the proof is not returned to IJTHF Editorial Office within 48 hours, it may be necessary to reschedule the paper for a subsequent issue. Extensive alteration in proof may cause delays in publication.
