The optim.m.levels of Lysine and Glutam.ne needed for growth perform.nce and m.intenance of the chicken broilers were evaluated in a random.zed 3 × 4 factorial arrangem.nt of dietary treatm.nts. The battery cages m.asured 99 × 66 × 25 cm.that can be sufficient for 5 birds. Day old Chicken broilers totaling 180 were assigned to dietary treatm.nts com.rising of 3 concentrations of Lysine (0.85, 1.14, and 1.42) each in com.ination with 4 concentrations of Glutam.ne (0, 1, 2, and 3). Each dietary treatm.nt was replicated 3 tim.s and each replication had 5 birds. The birds were given feed and water ad libitum.with a 23-hour light regim.n for a period of 4 weeks. Then, the experim.ntal birds were evaluated for body weight gain, feed consum.tion, and feed conversion in order to determ.ne their optim.m.requirem.nt for dietary Lysine and Glutam.ne. Based on the findings of this study, the highest perform.nce was observed in birds fed the diet supplem.nted with 1.42 lysine and 1% glutam.ne, but the highest im.rovem.nt in feed conversion was observed in diet contain 1.14 and 1.42 with 1% and 3% glutam.ne, respectively. Birds fed 1.42 lysine and 1% glutam.ne had the highest total body weight gain and feed consum.tion. The lysine requirem.nts in the diet for Chicken are between 1.14 and 1.42 with glutam.ne level of 1%.

Healthcare wastes contain potentially harm.ul m.croorganism., inorganic and organic com.ounds that pose a risk to hum.n health and the environm.nt. Incineration is a com.on m.thod em.loyed in healthcare waste m.nagem.nt to reduce volum., quantity, toxicity as well as elim.nation of m.croorganism.. However, som. of the substances rem.in unchanged during incineration and becom. part of bottom.ash, such as heavy m.tals and persistent organic pollutants. m.nitoring of pollution by heavy m.tals is im.ortant since their concentrations in the environm.nt affect public health. The goal of this study was to determ.ne the levels of Copper (Cu), Zinc (Zn) Lead (Pb), Cadm.um.(Cd) and Nickel (Ni) in the incinerator bottom.ash in five selected County hospitals in Kenya. Bottom.ash sam.les were collected over a period of six m.nths. Sam.le preparation and treatm.nt were done using standard m.thods. Analysis of the heavy m.tals were done using atom.c absorption spectrophotom.ter, m.del AA-6200. One-Way Analysis of Variance (ANOVA) was perform.d to determ.ne whether there were significant differences on the m.an levels of Cu, Zn, Pd, Cd and Ni in incinerator bottom.ash from.the five sam.ling locations. A post-hoc Tukey’s Test (HSD) was used to determ.ne if there were significant differences between and within sam.les. The significant differences were accepted at p ≤ 0.05. To standardize the results, overall m.an of each m.tal from.each site was calculated. The m.tal m.an concentration values were com.ared with existing perm.ssible levels set by the WHO. The concentrations (m./kg) were in the range of 102.27 - 192.53 for Cu, Zn (131.68 - 2840.85), Pb (41.06 - 303.96), Cd (1.92 - 20.49) whereas Ni was (13.83 - 38.27) with a m.an of 150.76 ± 77.88 for Copper, 131.66 ± 1598.95 for Zinc, 234.60 ± 262.76 for Lead, 12.256 ± 10.86 for Cadm.um.and 29.45 ± 18.24 for Nickel across the five sam.ling locations.

We have previously evaluated asbestos exposure associated with various m.intenance procedures on light aircraft. The purpose of this study was to evaluate asbestos exposure during engine m.intenance on light aircraft. This test was designed to evaluate the potential for asbestos exposure to m.chanics and others who rem.ve asbestos-containing engine gaskets from.reciprocating style aircraft engines. Utilized in this test was an air cooled, horizontally opposed, aviation gasoline burning engine, assem.led during 1986 and operated interm.ttently up into 2015, having accum.lated 1680 hours run tim.. Nearly 75% of the asbestos-containing gaskets installed during 1986 were still in place at the tim. of testing. Chrysotile asbestos contents of such gaskets ranged from.55% to 60% by area, for those of sheet style and 5% by area, for the spiral wound m.tal/asbestos style. Despite the levels of effort required to effect gasket rem.vals, the professional aircraft m.chanic was not exposed to airborne asbestos fibers at the lower lim.ts of sam.ling and analytical detection achieved;all of which were substantially less than the current Occupational Safety and Health Adm.nistration Perm.ssible Exposure Lim.ts for asbestos. The results of this testing indicate an absence of gasket related asbestos exposure risk to m.chanics who work with light aircraft engines, including those having asbestos-containing gaskets. These results are consistent with the findings of m.yarek and Van Orden who studied the asbestos exposure risk occasioned during overhaul of larger radial style reciprocating aircraft engines [1].

Corrosiveness or scaling is an inherent threat to oil operations. The prim.ry cause for this threat is the presence of water having com.lex geochem.cal m.trix. Unanticipated water production, particularly if it contains unwanted im.urities, can significantly im.act hydrocarbon production. The current paper discusses the degree of threat posed to oil operation facilities based on the water characteristics. m.thodology involved the collection and analysis of water sam.les from.m.jor sources in oil industry such as groundwater, wellheads and seawater. The param.ters tested include geochem.cal, m.crobiological and pollutants. The lab data was used to develop scaling and corrosion prediction indices such as Langelier Saturation Index (LSI), Ryznar Stability Index (RSI) and Puckorius Scaling Index (PSI). The study indicated varying water chem.stry for different sources. m.xing of those waters m.y lead to ionic saturation and scaling in different facilities. Presence of the SRB and GAB in som. water sources also posed threat to water system.by form.ng fouling and corrosion. Seawater used for offshore oilfields water injection to m.intain reservoir pressure and im.rove oil recovery showed scaling tendency, whereas under different reservoir pressure, it can cause corrosion. Som. of the sam.les also had corrosion residuals such as iron, which indicated active corrosion. Current study showed higher alkalinity with high sulfate for one groundwater sam.le with presence of active corrosion residuals such as dissolved iron and m.nganese. The study showed positive value for LSI which indicated supersaturation of the water sam.les with respect to calcium.carbonate (CaCO3) and scale form.ng. Sim.larly, for RSI and PSI, the value was below six which confirm.d the scaling potential for all the sam.les. Even though the index value was pointing towards scaling potential, the geochem.stry, m.crobiology and presence of other im.urities indicated corrosion threat to the oil and g

This cross-sectional study investigates a connection between fem.le infertility and obesity across various regions of the United States, utilizing data from.the NIH’s “All of Us” Researcher Workbench. Analysis suggested that the Southern region exhibited the highest percentage of concurrently infertile and obese fem.les at 32.3%, in contrast to the lowest in the Western region at 28.7%. The findings underscore the significant regional disparities in obesity-related infertility, particularly in m.dically underserved areas where healthcare access is lim.ted. The study highlights the urgent need for targeted public health interventions, particularly in the Southern United States, to address the rising prevalence of obesity and its im.act on infertility. Further, these results advocate for enhanced public health education and policies aim.d at im.roving healthcare accessibility, with the goal of m.tigating the adverse effects of obesity on reproductive health.
