This study aims to examine the variability of rainfall and temperature based on spatio-statistical analysis. Data for the study was gotten from the Nigerian Meteorological Agency and subjected to statistical analysis using mean, standard deviation, time series analysis, t-test and correlation. The results of the study revealed that the mean rainfall in the area is 108.6 mm, mean temperature is 28o C and mean sunshine is 4.7 hours. The result further revealed that mean onset date in the state is 13th march, mean cessation date is 10th October while the mean length of rainy season is 223 days. The result also showed that rainfall anomaly index in the area ranged between -2.12 and 2.28 while temperature anomaly ranged between -2.31 and 1.73.  The correlation coefficient showed that cessation (0.408) and Length of rainy season (0.406) is significantly related to rainfall, sunshine hours (0.380) and Average temperature (0.867) is significantly related to minimum temperature, sunshine hours (-0.389) and average temperature (0.749) is significantly related to maximum temperature while onset (-0.642) and cessation (0.509) is significantly related to length of rainy season. However,there is a significant difference in onset dates, cessation dates and length of rainy season in the area. The area is experiencing a significant increase in temperature, rainfall and sunshine hours and recommends that more tress should be planted in the area and Nigerian meteorological agency should also inform farmers about the onset of the rains so as to help the farmers prepare for the planting season.

Hatching Rates

This study investigated the boreal digging frog, Kaloula borealis, to determine the egg hatching period and whether the hatching period is affected by incubation temperature. The results of this study showed that all the eggs hatched within 48 h after spawning, with 28.1% (±10.8, n=52) hatching within 24 h and 99.9% (±0.23, n=49) within 48 h after spawning. A significant difference was noted in the mean hatching proportion of tadpoles at different water temperatures. The mean hatching rates between 15 and 24 h after spawning was higher at a water temperature of 21.1 (±0.2) °C than at 24.1 (±0.2) °C. These results suggest that incubation temperature affected the early life stages of the boreal digging frog, since they spawn in ponds or puddles that form during the rainy season.

Length Of Gestation

1. A survey and. statistical analysis of the records of litters born in the N.I.R.D. herd of Large White pigs over a period of 16 years are presented.2. The mean length of gestation was 114 days for both gilts and sows.3. The mean numbers of pigs born alive and born dead per litter from gilts, 10·0 and 0·2 respectively, were both significantly smaller than the corresponding figures for sows, 11·8 and O·8. No seasonal differences were found.4. The mean total losses of pigs from birth to weaning at 8 weeks were 29·5% of pigs born alive. The losses in litters from gilts, 23·0%, were significantly smaller than in litters from sows, 31·0%. The losses during the winter months both for gilts, 32·5%, and for sows, 35·9%, were significantly higher than during the summer months, 19·4% and 26·7% for gilts and sows respectively.5. Over 50% of the total losses were due to crushing by the dam, 74·1% of the losses from this cause occurring during the first 48 hr. after birth.6. The mean number of pigs weaned per litter was 8·0. The difference between the number weaned per litter from gilts, 7·7, and per litter from number of pigs was weaned per litter from sows during the summer months, 8·7, than during the winter months, 7·4.7. There was no significant difference between the number of male and of female pigs weaned.8. The mean weight at weaning was 29·9 lb., male pigs, 30·3 lb., being significantly heavier than females, 29·51b. Pigs in litters from gilts, 27·81b., were significantly lighter at weaning than those from sows, 30·0 lb., and for both gilts and sows, pigs reared during the summer months, 29·7 and 31·8 lb. respectively, were significantly heavier than those reared during the winter months, 25·9 and 28·2 lb. respectively.

This experiment was carried out to study the internal temperature regulation of a colony of Africanized honey bees (AFR), compared with hybrid Caucasian (CAU), Italian (ITA), and Carniolan (CAR) bees, during the period of one year and different size hives located in a sub-tropical region. The instant internal temperature, 33.7 ± 1.5° C for the AFR, 33.5 ± 1.4° C for the CAU, 33.7 ± 1.5° C for the ITA and 33.8 ± 1.4° C for the CAR, did not show any significant difference (P>0.05). The maximum temperature (36.1 ± 2.3° C) was statistically different (P<0.05) from the minimum (27.6 ± 5.3° C). There was no difference (P>0.05) in the mean internal temperature, between the nucleus (31.7 ± 6.3° C) and the brood nest (32.1 ± 5.3° C) measured between two and four o'clock in the afternoon.

Perivascular wall tumors (PWTs or haemangiopericytomas) are common in dogs, and they are clinically important in veterinary oncology, but there is no data on the occurrence of these tumors in dogs in Poland. The aim of the present study was an epidemiological analysis of canine perivascular wall tumors. The study included 136 dogs with recognized PWTs (whose frequency of occurrence was the same in females and males). The mean age of the dogs was 9.8±3.0 years, with no statistically significant difference between sexes. Among the dogs, 40.7% were mongrels, and 59.3% were purebred. Among the purebred dogs, 21 (26.3%) were German Shepherds, 17 (21.3%) were Boxers, 5 (6.3%) were Doberman pinchers and Rottweilers. Statistical analysis revealed that four breeds were predisposed to perivascular wall tumors in comparison to the general dog population: German Shepherds, Boxers, Doberman pinchers and Rottweilers. Moreover, large-breed (but not giant-breed) dogs were shown to be predisposed to PWTs. Tumors were located in the skin or subcutis of the entire body, mostly on the legs, more seldom on the trunk or the head. The most typical location for PWTs was the elbow area (11% of all cases).

The use of novel stimuli for obtaining nasalance measures in young children was the focus of this study. The subjects were 20 children without a history of communication disorders and 20 children at risk for velopharyngeal insufficiency (VPI). Each subject recited three passages; the standard Zoo Passage, and two novel stimuli that were named the Turtle Passage and the Mouse Passage. Like the Zoo Passage, the Turtle Passage contained no normally nasal consonants. The Mouse Passage was about 11% nasal consonants, which is similar to the Rainbow Passage. Statistical analysis showed no significant difference between the mean nasalance for the Zoo Passage and the Turtle Passage for either the subjects without risk of VPI (15.4% vs 15.7%) or for those at risk (30.4% vs 28.8%). Nasalance measures for the Mouse Passage were significantly higher than for either the Zoo Passage or the Turtle Passage. Listeners rated the stimuli on a 5-point equal-appearing intervals scale. The correlation coefficient between listener judgments of hypernasality and nasalance was significant for the Zoo Passage (r = 0.70) and for the Turtle Passage (r = 0.51) but not significant for the Mouse Passage (r = 0.32). Using cut-off scores of 22% for nasalance and 2.25 for hypernasality, the sensitivity for the Zoo Passage was 0.72, and for the Turtle Passage, 0.83.

Objective: To determine the number and pattern of palatal rugae in Nepalese subjects and to find the association of gender with the number and pattern of palatal rugae. Materials & Method: 200 Nepalese subjects comprising of 100 male and 100 female were randomly selected and their maxillary casts were examined for the palatal rugae length applying the classification proposed by Thomas and Kotze and palatal rugae pattern was recorded using the classification given by Kapali. Statistical analysis using Student t-test was applied for comparing the number of palatal rugae between right and left sides. Chi square test was used to find the association between gender and number of rugae as well as the pattern. Result: The study demonstrated that the mean number of primary palatal rugae on left side was predominant, similarly wavy pattern was the most predominant in Nepalese subjects. No statistical significant difference was noticed in the palatal rugae number and pattern between the gender groups. Conclusion: The study found predominant palatal form in Nepalese subjects which might have superior effectiveness in population differentiation and may be used as an effective tool in forensic odontology identification.

The rubber borers, called of the bark beetles, is the most important pest of the rubber trees in the world. The effect of the pheromone releasing measure, a kind of ecological control method, was investigated over 2 years in Nanbao Farm, Lingao county, Hainan, China. The pheromone used was (s)-(+)-Ipsidenol, a commercially available rubber borers aggregation pheromone. There were 6 treatments, including 10m, 20m, 30m, 40m, 50m and 100m distance. Pheromone lures were changed monthly at which time the traps were moved to a different location within the stand. There were no significant differences in 30m distance catches of the rubber borers per traps. Meanwhile, there was no significant difference in plant damage between the pheromone treatment of 2.5 mg/mL and 3 mg/mL traps. The results also showed that the relationship between the mean number of the rubber borers per 5 days and average temperature was not significant.
