Effect of Parallelepipedic and Spherical Shapes Dimensions on Convective Drying Characteristics of Sweet Potato | Chapter 1 | Science and Technology: Recent Updates and Future Prospects Vol. 12

 

The aim of this work is to determine the characteristic dimension governing transfers during convective drying. Parallelepipedic and cylindrical form of sweet potato was used. This present work determines this characteristic dimension for the samples of sweet potatoes of parallelepipedal and cubic shapes. We have fixed the characteristic dimension in the direction of the thickness of the samples of parallelepiped shape and of the radius for the samples of cylindrical shape. For the parallelepidic form P_L-l-e, the thickness e is set to 1cm while the length L and the width l vary. The results show that the variation of the dimensions other than the thickness e does not influence the transfers in a considerable way. The same observation is made for the cylindrical samples c_H-R by keeping the radius R constant. From the foregoing, the thickness of the parallelepiped samples turns out to be the dimension that best governs the transfers versus its length and width. Likewise, with regard to cylindrical samples, the fixed radius smaller than the height is the characteristic dimension of the transfers in the product during its convective drying. If we know that the initial size is an important factor for transfers during convective drying (Ouoba, 2013), this present work therefore allows us to conclude that the thickness of the parallelepiped-shaped samples and the radius of the cylindrical shapes, all being the smallest dimensions, characterize the transfers. This work highlights the importance and the existence of a characteristic dimension that dictated the transfers during the convective drying of organic products such as sweet potatoes.

Age, Size, and Sectors in IPO Performance: A Comprehensive Analysis | Chapter 10 | An Overview on Business, Management and Economics Research Vol. 4

 This study offers a new perspective on the stock price conduct of firms that went public through IPOs between 2009 and 2019. It tests the impact of their size, age and for-profit businesses on future performance. The analysis surrounds data from 1611 IPOs extending across 11 economic sectors, engaging the event study plan. The findings provide solid evidence that a firm's size and age be a part of predictors for both temporary and long-term price performance. In addition, skilled is a significant alternative in the long-term performance middle from two points sectors and 'tween small and large firms inside each sector, accompanying smaller firms exhibiting more distinct underperformance over time. This wonder can be assign to differences in publicly feasible information, seen risk, and resource availability betwixt older, best firms and their younger, smaller matches. Notably, the study reveals specific sector-distinguishing patterns in the age of firms going public. There is a clear tendency for firms in the healthcare and science sectors to make known at a relatively younger age than those in additional sectors, emphasize the strategic advantages of early IPOs for these rules. These findings hold suggestions for asset pricing and offer valuable acumens for investors busy in IPOs.

Total Body Rings Increase with Latitude and Decrease with Precipitation in Forest Millipedes Centrobolus Cook, 1897| Chapter 13 | New Visions in Biological Science Vol.9

 Juliformia's size is determined by two factors: body diameter and number of rings. The researchers wanted to see if there were any links between latitude and precipitation and body rings and sexual size dimorphism (SSD) in Centrobolus. The number of body rings in females and latitude (r=-0.53, Z score=-2.35, n=19, p0.01) and the number of body rings in males and latitude (r=-0.41, Z score=-1.74, n=19, p=0.04) had a significant link. The number of body rings in females and precipitation (r=-0.60, Z score=-2.76, n=19, p0.01), as well as the number of body rings in males and precipitation (r=-0.60, Z score=-2.76, n=19, p0.01). The number of body rings differed somewhat between males and females (W=22.5, Z=-1.61, n=19, p=0.05); females had more rings. Lower precipitation, not temperature, is connected to an anamorphic rise in the number of body rings in higher latitudes (South).

Why Sexual Size Dimorphism Increases with Longitude, Precipitation and Temperature and Decreases with Latitude in Forest Millipedes Centrobolus Cook, 1897| Chapter 9 | New Visions in Biological Science Vol.9

 The goal of this research was to see what happened when Bergmann's Rule collided with Rensch's Rule Sexual Size Dimorphism (SSD) and body size varied as a result of eco-geographical factors. In the woodland millipede genus Centrobolus, body size and SSD were associated with latitude, longitude, precipitation, and temperature. SSD and longitude (r=0.37, Z score=1.71, n=22, p=0.04), precipitation (r=0.29, Z score=1.28, n=22, p0.010), and temperature (r=0.34, Z score=1.49, n=22, p0.07) all had significant positive relationships. SSD and latitude had a significant relationship (r=-0.44, Z score=2.05, n=22, p=0.02). Larger females and greater SSD exist in warmer, wetter north-eastern settings, indicating eco-geographical variation in polygynandrous reproductive systems.

The Relationships between Sexual Size Dimorphism and Precipitation and Female Size and Temperature in Sphaerotherium Brandt, 1833 | Chapter 8 | New Visions in Biological Science Vol.9

 Sexual Size Dimorphism (SSD) was reversed in Diplopoda, as it was in the majority of invertebrates. The goal was to examine SSD in the Sphaerotherium genus. Male and female morphological data for S. cinctellum, S. commune, S. compressum, S. punculatum, S. spinatum, S. tenuitarse, and S. tuberosum were gathered from the literature, including male and female width, volume, and SSD. The five morphological variables were regressed against latitude, precipitation, and temperature using linear regressions. SSD was substantially associated to the mating system, seasonality, and oviposition (r=0.76, Z score=1.97, n=7, p=0.02) and was strongly correlated with precipitation (r=0.76, Z score=1.97, n=7, p=0.02). Female breadth was associated to temperature (r=0.75, Z score=1.93, n=7, p=0.03) and fecundity selection (r=0.75, Z score=1.93, n=7, p=0.03). Temperature was only moderately associated to SSD (r=0.61, Z score=1.42, n=7, p=0.08).

Copulation duration Allometry in Worm-like Millipedes (Diplopoda: Chilognatha: Helminthomorpha) | Chapter 5 | New Visions in Biological Science Vol.9

 Copulation duration variance in mate-guarding worm-like millipedes was examined as one of many determining factors of copulation duration across arthropods. In worm-like millipedes, the goal was to compute copulation duration allometry. The null hypothesis was that mean copulation duration and variance were unaffected by body mass. The length of copulation and the standard deviation squared for 20 millipede populations were taken from the literature. The length of copulation was highly associated to variation (r=0.87, Z score= 5.74, n=21, p0.01). These included forest species such as Gigantowales chisholmi (0.09) and Alloporus uncinatus (Mazowe-Hwange) (4238.01). (C. anulatus, C. inscriptus, C. ruber). Female mass (r=0.68, Z score=2.89, n=15, p0.01) was shown to be linked with copulation duration variance (r=0.68, Z score=2.89, n=15, p0.01). Male mass (r=0.80, Z score=3.85, n=15, p0.01) was shown to be linked with copulation length variance (r=0.80, Z score=3.85, n=15, p0.01). These relationships were not significantly different (z=-0.67, n=15, 15, p=0.50). Male mass was only slightly linked with copulation duration (r=0.40, Z score=1.55, n=16, p=0.06). Female mass was not associated to copulation duration (r=0.33, Z score=1.22, n=16, p=0.11). These correlation coefficients were identical (z=0.23, n=16, 16, p=0.82). When intraspecific variation in copulation length was controlled, it was shown that it was negatively related to size and connected with the severity of sperm competition (equal). The duration of copulation is controlled by males based on the mass and intensity of sperm competition.
