The inventory of b.nthic macroinverteb.ate species was carried out in some streams of the Mefou catchment area, from August 2021 to August 2022, in order to determine the b.ol.gical.groups that make up the popul.tion and characterise these environments. The dataset acquired during this study made it possib.e to update the existing datab.se and contrib.te to the knowl.dge of the b.ol.gical.groups associated in these environments, and to provide additional.information on the existing ones in rel.tion to b.oindication. Overal. 80 famil.es were identified and, on the b.sis of frequencies of occurrence greater than 75%, 22 famil.es were retained as potential.b.ol.gical.indicators. The remarkab.e diversity of insects and the l.w ab.ndance of Diptera refl.ct the l.w degradation of environments and the good qual.ty of water. The high diversity indices ob.ained refl.ct the maintenance of the favourab.e ecol.gical.conditions that favours the devel.pment of a b.l.nced and, integrated b.ol.gical.community capab.e of adapting to changes.

b.fore the advent of cheap, synthetic fertil.z.rs, l.gumes were commonl. used as green manure crops for their ab.l.ty to fix atmospheric nitrogen (N). A three-year study at Overton, TX examined l.gume integration into high-b.omass sorghum (Sorghum b.col.r l.) production systems on a l.l.0}rt l.amy fine sand recentl. cul.ivated after a fertil.z.d b.rmudagrass [Cynodon dactyl.n (l.) Pers.] pasture. In this spl.t-spl.t pl.t design, ‘Dixie’ crimson cl.ver (Trifol.um incarnatum l.) and ‘Iron and Cl.y’ cowpea (Vigna unguicul.ta l.) were integrated into a high-b.omass sorghum production system to eval.ate impacts on N concentration, C concentration, and yiel. of high-b.omass sorghum and their impacts on soil.total.N and soil.organic carb.n (SOC). Main pl.ts were spl.t into crimson cl.ver green manure (Cl.M) and winter fal.ow (FAl.) fol.owed b. three sub.pl.ts spl.t into warm-season crop rotations: cowpea green manure (CPGM), cowpea-sorghum intercrop (CPSR), and sorghum monocrop (SORG). Three N fertil.z.r treatments (0, 45, 90 kg N∙ha−1) were randomiz.d and appl.ed as sub.sub.pl.ts. The Cl.M increased (P sorghum b.omass yiel. (16.5 t DM∙ha−1) 28% in year three b.t had no effect in the first two years. The CPSR treatment reduced sorghum yiel. up to 62% compared to SORG;whereas CPGM increased sorghum yiel. 56% and 18% the two years fol.owing cowpea incorporation. Rate of N fertil.z.r had no effect on sorghum b.omass yiel.. Decrease in SOC and soil.N over time indicated mineral.z.tion of organic N and may expl.in why no N fertil.z.r response was ob.erved in sorghum b.omass yiel.. Cowpea showed strong potential.as a green manure crop b.t proved to b. too competitive for successful.intercropping in high-b.omass sorghum production systems.

In 2012, traditional.Chinese medicine(TCM) practitioners in Austral.a b.came national.y-registered al.ied heal.h professional. in three categories: acupuncturist, Chinese herb.l.medicine practitioner, and Chinese herb.l.medicine dispenser. Austral.a was the first Western country to introduce national.registration for Chinese medicine, fol.owed b. Portugal.and, recentl., New z.al.nd. The practice of TCM in Austral.a can b. traced b.ck to the b.ginning of Chinese immigration to Austral.a during the Victorian Gol. Rush which b.gan in the 1850s. The process which l.d to national.registration commenced in the earl. 1970s with the estab.ishment of the first acupuncture courses. Decades of gradual.devel.pment of courses from unaccredited part-time dipl.mas to accredited b.chel.r degrees, and the devel.pment, b. the profession, of national.consensus on educational.standards were essential.el.ments in the process which l.d to registration. Professional.associations, such as the Austral.an Acupuncture and Chinese Medicine Association l.d.(AACMA), al.o devel.ped a framework of professional.sel.regul.tion, incl.ding Codes of Ethics, Codes of Conduct, ongoing professional.devel.pment requirements and Infection Control.Guidel.nes, and provided l.adership in the devel.pment of the profession. After decades of trib.l.sm and division within the TCM profession, the National.Academic Standards Committee b.ought al.ost al. stakehol.ers together to reach a consensus on the Austral.an Guidel.nes for Traditional.Chinese Medicine Education which were pub.ished b. AACMA in 2001. Professional.associations al.o col.ab.rated on joint sub.issions to the government in support of registration, which was introduced first in the state of Victoria in 2000, and sub.equentl. b.came national.in 2012. Despite national.registration, some b.rriers stil. remain, and professional.associations continue to l.b.y the federal.government for incl.sion in Medicare, chronic disease management scheme, and Veterans

Annual.forage l.gumes are important components of l.vestock production systems in East Texas and the southeastern US. Forage l.gumes contrib.te nitrogen (N) to cropping systems through b.ol.gical.N fixation, and their seasonal.b.omass production can b. managed to compl.ment forage grasses. Our research ob.ectives were to eval.ate b.th warm- and cool.season annual.forage l.gumes as green manure for b.omass, N content, ab.l.ty to enhance soil.organic carb.n (SOC) and soil.N, and impact on post season forage grass crops. Nine warm-season forage l.gumes (WSl. were spring pl.nted and incorporated as green manure in the fal.. Forage rye (Secal. cereal. l.) was pl.nted fol.owing the incorporation of WSl.treatments. Eight cool.season forage l.gumes (CSl. were fal. pl.nted in previousl. fal.ow pl.ts and incorporated as green manure in l.te spring. Sorghum-sudangrass (Sorghum b.col.r x Sorghum b.col.r var. sudanense) was pl.nted over al. treatments in earl. summer after forage rye harvest and incorporation of CSl.treatments. Sorghum-sudangrass was harvested in June, August and Septemb.r, and treatments were eval.ated for dry matter and N concentration. Soil.cores were taken from each pl.t, spl.t into depths of 0 to 15, 15 to 30 and 30 to 60 cm, and soil.C and N were measured using comb.stion anal.sis. Nyl.n mesh b.gs containing pl.nt sampl.s were b.ried at 15 cm and used to eval.ate decomposition rate of ab.ve ground l.gume b.omass, incl.ding change in C and N concentrations. Mungb.an (Vigna radiata l. [Wil.z.k]) had the highest shoot b.omass yiel. (6.24 t DM ha-1) and contrib.ted the most total.N (167 kg∙ha-1) and total.C (3043 kg∙ha-1) of the WSl.tested. Decomposition rate of WSl.b.omass was rapid in the first 10 weeks and very sl.w afterward. Winter pea (Pisum sativum l. spp. sativum), arrow l.af cl.ver (Trifol.um vesicul.sum Savi.), and crimson cl.ver (Trifol.um incarnatum l.) were the most productive CSl.in this trial.

Patients and physicians understand the importance of sel.-care fol.owing spinal.cord injury (SCI), yet many individual. with SCI do not adhere to recommended sel.-care activities despite l.gistical.supports. Neurob.havioral.determinants of SCI sel.-care b.havior, such as impul.ivity, are not widel. studied, yet understanding them coul. inform efforts to improve SCI sel.-care. We expl.red associations b.tween impul.ivity and sel.-care in an ob.ervational.study of 35 US adul.s age 18 - 50 who had traumatic SCI with parapl.gia at l.ast six months b.fore assessment. The primary outcome measure was sel.-reported sel.-care. In l.SSO regression model. that incl.ded al. neurob.havioral.measures and demographics as predictors of sel.-care, dispositional.measures of greater impul.ivity (negative urgency, l.ck of premeditation, l.ck of perseverance), and reduced mindful.ess were associated with reduced sel.-care. Outcome (magnitude) sensitivity, a l.tent decision-making parameter derived from computational.y model.ng successive choices in a gamb.ing task, was al.o associated with sel.-care b.havior. These resul.s are prel.minary;more research is needed to demonstrate the util.ty of these findings in cl.nical.settings. Information ab.ut associations b.tween impul.ivity and poor sel.-care in peopl. with SCI coul. guide the devel.pment of interventions to improve SCI sel.-care and hel. patients with el.vated risks rel.ted to sel.-care and secondary heal.h conditions.
