Tropical Pastures For Dairy Heifers In The South-Eastern Region Of Brazil, S Aronovich, S R. De Carvalho, Mm Aronovich Jan 2025

Tropical Pastures For Dairy Heifers In The South-Eastern Region Of Brazil, S Aronovich, S R. De Carvalho, Mm Aronovich

IGC Proceedings (1977-2023)

A number of experiments using improved tropical pastures (mostly Digltaria decumbems cv. Transvala) for heifers were made in the south-eastern region of Brazil from 1970. The results are presented as: (A) experiments with heifers during· the nursing period, (B) experiments with heifers after. weaning and (C) experiments with heifers older than 6 months. The results and the economical analyses lead to the following conclusions: ( 1) the use of well managed, improved tropical pastures enables adequate growth and development of dairy heifers, (2) the heifers reach sexual maturity before 20 months of age, and (3) the cost of replacement heifers …

Mineral Supplementation And Phosphorus Fertilizer Application On Native Pastures In North-East Argentina, R M. Pizzio, O Royo Pallares Jan 2025

Mineral Supplementation And Phosphorus Fertilizer Application On Native Pastures In North-East Argentina, R M. Pizzio, O Royo Pallares

IGC Proceedings (1977-2023)

Extensive cattle production systems in north-east Argentina are based on the use of native pastures. One of the most important limiting factors to improve production is the acute phosphorus deficiency of soils and pastures. A large experiment was set up to study the effect of phosphorus fertiliser and mineral supplementation on the live­weight gain of steers of 2 ages grazing native pastures. Supplementation with a mixture of bone meal and salt, residual effect of P fertilisation, and both treatments applied together increased the annual animal live-weight gain by 60, 66 and 106%, respectively. The response of younger steers to fertiliser …

Climate Change Aggravates Bird Mortality In Pristine Tropical Forests, Jared Wolfe, David A. Luther, Vitek Jirinec, Jeremy Collings, Erik I. Johnson, Robert O. Bierregaard, Philip C. Stouffer Jan 2025

Climate Change Aggravates Bird Mortality In Pristine Tropical Forests, Jared Wolfe, David A. Luther, Vitek Jirinec, Jeremy Collings, Erik I. Johnson, Robert O. Bierregaard, Philip C. Stouffer

Michigan Tech Publications

Stable understory microclimates within undisturbed rainforests are often considered refugia against climate change. However, this assumption contrasts with emerging evidence of Neotropical bird population declines in intact rainforests. We assessed the vulnerability of resident rainforest birds to climatic variability, focusing on dry season severity characterized by hotter temperatures and reduced rainfall. Analyzing 4264 individual bird captures over 27 years, we found that harsher Amazonian dry seasons significantly reduced apparent survival for 24 of 29 species, with longer-lived species being more strongly affected. Our model predicted that a 1°C increase in average dry season temperature would reduce the mean apparent survival …

Crosstalk Between Nnos/No And Cox-2 Enhances Interferon-Gamma-Stimulated Melanoma Progression, Anika Patel, Shirley Tong, Moom R. Roosan, Basir Syed, Amardeep Awasthi, Richard B. Silverman, Sun Yang Jan 2025

Crosstalk Between Nnos/No And Cox-2 Enhances Interferon-Gamma-Stimulated Melanoma Progression, Anika Patel, Shirley Tong, Moom R. Roosan, Basir Syed, Amardeep Awasthi, Richard B. Silverman, Sun Yang

Pharmacy Faculty Articles and Research

Background/Objectives: Interferon gamma (IFN-γ) in the melanoma tumor microenvironment plays opposing roles, orchestrating both pro-tumorigenic activity and anticancer immune responses. Our previous studies demonstrated the role of neuronal nitric oxide synthase (nNOS) in IFN-γ-stimulated melanoma progression. However, the underlying mechanism has not been well defined. This study determined whether the nNOS/NO and COX-2/PGE2 signaling pathways crosstalk and augment the pro-tumorigenic effects of IFN-γ in melanoma. Methods: Bioinformatic analysis of patient and cellular proteomic data was conducted to identify proteins of interest associated with IFN-γ treatment in melanoma. Changes in protein expression were determined using various analytical techniques including …

The Role Of Gsk-3Α Inhibition In Attenuating Lps-Induced Inflammation In Raw 264.7 Cells, Oluwaseyi Oyewole Jan 2025

The Role Of Gsk-3Α Inhibition In Attenuating Lps-Induced Inflammation In Raw 264.7 Cells, Oluwaseyi Oyewole

Theses and Dissertations

Glycogen synthase kinase-3 (GSK-3), an enzyme that modulates glucose metabolism, has been recognized as an essential target in major inflammatory diseases based on its great specificity in substrate recognition. GSK-3β has been connected to cancer, obesity, liver diseases, and neurological diseases. Nonetheless, the other GSK-3 isoform, GSK-3α, is much less studied. Previous studies from our laboratory showed that inhibiting GSK-3α potentially confers an anti-inflammatory response when tested on microglia. However, little has been documented regarding the exact mechanism by which GSK-3α exerts its effect. One of the potential mechanisms involving its anti-inflammatory effect could be partially attributed to activating the …

Evaluating The Performance Of Broccoli (Brassica Oleracea Var. Italica) In The Sandponics System Using Brackish Water With Biochar And Compost, Gabriel Oyebode Jan 2025

Evaluating The Performance Of Broccoli (Brassica Oleracea Var. Italica) In The Sandponics System Using Brackish Water With Biochar And Compost, Gabriel Oyebode

Theses and Dissertations

Some of the most pronounced effects of climate change on agricultural output include the depletion of freshwater resources and heightened salinization of arable land, especially in arid and semi-arid regions, adversely affecting crop yields. Many economic vegetable crops including members of the brassica family are sensitive to salt-stress. The use of organic soil amendments such as biochar and compost as complimentary nutrient sources in the sandponics system can improve the performance of crops. The study aimed to evaluate the effect of organic amendment on the growth performance and yield of broccoli and Nile tilapia (Oreochromis niloticus) under brackish …

Under The Bay: Analysis Of Green Sea Turtle (Chelonia Mydas) Dive Behavior In The Urban San Diego Bay, Emily Carter Jan 2025

Under The Bay: Analysis Of Green Sea Turtle (Chelonia Mydas) Dive Behavior In The Urban San Diego Bay, Emily Carter

Theses

Sea turtles are air-breathing marine reptiles that spend their lives performing dives to travel, forage, and rest. Several dive types have been previously recorded for sea turtles, each type being associated with a different set of behaviors. U-dives, or Type 1 dives are widely characterized by extensive benthic periods preceded by and concluding with abrupt descent and ascent phases respectively (Minamikawa et al. 1997; Houghton et al. 2002; Seminoff et al. 2006). These dives are widely affiliated with turtle resting behavior though can be indicative of additional activities including benthic travel and foraging. Previous research of green turtle dive behavior …

Determining The Physiological And Behavioral Tolerance To Hypoxia In Two Species Of Rockfish (Sebastes Spp.), Makenna Chan Jan 2025

Determining The Physiological And Behavioral Tolerance To Hypoxia In Two Species Of Rockfish (Sebastes Spp.), Makenna Chan

Theses

In the eastern North Pacific, the oxygen minimum zone naturally shoals seasonally and impacts demersal fish habitat along the continental margins and on offshore seamounts. This hypoxic layer has been shoaling in recent decades, likely affecting the habitat and distribution of commercially-important fish species such as rockfishes (genus Sebastes). Respirometry and shuttle box behavioral experiments were used to determine the hypoxia sensitivities of two rockfish species with contrasting movement patterns and habitat use: cowcod (Sebastes levis) and bocaccio (Sebastes paucispinis). Although both species inhabit similar deep-water, rocky-reef habitat, they have different lifestyles, in which cowcod …

The Molluscs From The French School On Yefet Street, Yafo (Jaffa) (Pp. 529–532), Inbar Ktalav Jan 2025

The Molluscs From The French School On Yefet Street, Yafo (Jaffa) (Pp. 529–532), Inbar Ktalav

'Atiqot

An assemblage of 76 malacological remains was retrieved from the French School in Yafo. It includes 11 species of local Mediterranean seashells and land snails, one indo-pacific bivalve, one bivalve from the Nile River and two fragments of freshwater bivalves. A cross made of mother of pearl was found in a soil accumulation of the late Ottoman period. The shells were used as construction material and as objects of aesthetic or symbolic value, possibly amulets.

The Zooarchaeological Assemblage From The French School On Yefet Street, Yafo (Jaffa) (Pp. 513–527), Nimrod Marom

'Atiqot

A small assemblage of 158 identified animal bones was retrieved from Crusader- and late Ottoman-period contexts at the French School. The bone samples from both periods consisted mainly of cattle and caprines, as well as some pig, donkey, horse and chicken bones. The relative frequency of pig bones in the Ottoman period might point to a religious tolerance toward the consumption of equid and wild boar. This may attest to a poverty-stricken Muslim population, or to the presence of immigrants from the Maghrebi Islam.

Remains From The Crusader And Late Ottoman Periods At The French School On Yefet Street, Yafo (Jaffa) (With Contributions By Edna J. Stern, Brigitte Ouahnouna, Alexander Glick And Polina Spivak) (Pp. 469–496), Yoav Arbel, Limor Talmi Jan 2025

Remains From The Crusader And Late Ottoman Periods At The French School On Yefet Street, Yafo (Jaffa) (With Contributions By Edna J. Stern, Brigitte Ouahnouna, Alexander Glick And Polina Spivak) (Pp. 469–496), Yoav Arbel, Limor Talmi

'Atiqot

The French School excavation encompassed three areas (A, B, C): Area A yielded a substantial volume of Crusader-period pottery, perhaps alluding to the existence of a Crusader-period moat, and late Ottoman-period building remains and a water reservoir; in Area B, a Crusader-period pedestal, as well as a late Ottoman-period well, channels and wall foundations, were exposed; and in Area C were found the remains of Crusader-period pedestals, late Ottoman-period wall remains and two pit graves of uncertain date. The remains from the late Ottoman period point to Yafo’s orderly spatial organization during the nineteenth century.

The Animal Bones From Ben Gamli’El Street, Yafo (Jaffa) (Pp. 461–464), Nimrod Marom

'Atiqot

The excavation on Ben Gamli’el Street yielded a small assemblage of 40 animal bones retrieved from the ashy fill of a large Hellenistic-period ash pit (Stratum III). The bones represent farm animals, mostly goats, cattle and pigs, possibly indicating the economy of the rural hinterland that supported the urban settlement of Yafo. The presence of the dog burial and the high occurrence of pig bones probably attests to a non-Jewish community.

Building Remains From The Hellenistic, Byzantine And Late Ottoman Periods On Ben Gamli’El Street, Yafo (With A Contribution By Polina Spivak) (Jaffa) (Pp. 389–402), Yoav Arbel

'Atiqot

Two areas (A, B) were excavated on Ben Gamli’el Street, yielding building remains and a waste pit from the Hellenistic period (fourth–second centuries BCE), a large quantity of Byzantine-period pottery (fourth–seventh centuries CE) and two late Ottoman-period walls (late nineteenth–early twentieth centuries CE). During the Hellenistic period, which appears to have spanned both the Ptolemaic and Seleucid periods, the city seems to have been settled by a pagan population. During the Byzantine period, the area was exploited for intensive agricultural activities and industries and served as the hinterland of the city. Urban construction in this area was resumed on a …

Faunal Remains From The Magen Avraham Compound, Yafo (Jaffa) (Pp. 379–383), Nimrod Marom

'Atiqot

A small faunal assemblage dating to the Byzantine–Early Islamic and Ottoman periods was uncovered in the Magen Avraham Compound. The animal bones were deposited in an area that used to be part of the agricultural periphery of the town and consist mainly of caprine, cattle and equids. The presence of a relatively high number of equid remains suggests that the assemblage represents the disposal of whole animal carcasses outside the city.

'Atiqot

Human skeletal remains of at least ten adult individuals were found in the Magen Avraham Compound. Some of the bones were found scattered, while others were anatomically articulated, indicating primary burials, possibly in simple pit graves. The graves’ layout could not be traced, and no burial goods were retrieved; therefore, the dating of the finds is problematic.

Pottery Vessels And An Oil Lamp From The Persian, Hellenistic And Early Roman Periods In The Magen Avraham Compound, Yafo (Jaffa) (Pp. 279–287), Peter Gendelman

'Atiqot

A small amount of pottery from the Persian, Hellenistic and Roman periods was retrieved from mixed contexts in the Magen Avraham Compound. The pottery and oil lamp ascribed to the Early Roman period provide a glimpse into a period which is generally poorly represented at Yafo, perhaps attesting to a Jewish settlement in Yafo prior to the First Jewish Revolt. The pottery assemblage of the Mid- and Late Roman periods consisted almost exclusively of imported amphorae, reflecting Yafo’s engagement in Mediterranean trade.
